    In the present study, 217 rhizobacterial isolates were obtained from six different tea estates of Assam, India and subjected to preliminary in vitro plant growth promotion (PGP) screening for indole acetic acid (IAA) production, phosphate solubilization, siderophore production and ammonia production. Fifty isolates showed all the PGP traits and five isolates did not exhibit any PGP traits. These 50 potential isolates were further analyzed for quantitative estimation of the PGP traits along with the aminocyclopropane-1-carboxylate (ACC) deaminase, protease and cellulose production. After several rounds of screening, four rhizobacteria were selected based on their maximum ability to produce in vitro PGP traits and their partial 16S rRNA gene sequence analysis revealed that they belong to Enterobacter lignolyticus strain TG1, Burkholderia sp. stain TT6, Bacillus pseudomycoides strain SN29 and Pseudomonas aeruginosa strain KH45. To evaluate the efficacy of these four rhizobacteria as plant growth promoters, three different commercially important tea clones TV1, TV19, and TV20 plants were inoculated with these rhizobacteria in greenhouse condition and compared to the uninoculated control plants. Though, all the rhizobacterial treatments showed an increase in plant growth compared to control but the multivariate PCA analysis confirmed more growth promotion by TG1 and SN29 strains than the other treatments in all three clones. To validate this result, the fold change analysis was performed and it revealed that the tea clone TV19 plants inoculated with the E. lignolyticus strain TG1 showed maximum root biomass production with an increase in 4.3-fold, shoot biomass with increase in 3.1-fold, root length by 2.2-fold and shoot length by 1.6-fold. Moreover, two way ANOVA analysis also revealed that rhizobacterial treatment in different tea clones showed the significant increase (P < 0.05) in growth promotion compared to the control. Thus, this study indicates that the

    Sugarcane (Saccharum L. spp. hybrids) growers depend on breeding programs for new, high-yielding cultivars that have resistance to abiotic and biotic stresses, so breeders continually seek out widely adapted, high yielding germplasm to be used as parents for their programs. Cultivars are sometimes used for this purpose, but their use may be minimized to prevent genetic diversity erosion. The purpose of this study was to determine the importance of cultivars as parents in three USA (one in Florida and two in Louisiana) sugarcane breeding programs by quantifying the percentage of cultivars that had these parental groupings based on published registrations and crossing records. The percentage of cultivars with at least one commercial parent for each program was 81.8%, 77.5%, and 64.3% for the Houma (Ho), Louisiana, Canal Point (CP), Florida and Louisiana State University (LSU) programs, respectively, but cultivars were recently used as parents in only 11.8% (Ho), 16.39% (CP), and 34.3% (LSU) of crosses. The results indicate that the CP and Ho programs should consider increasing the use of cultivars as parents in their breeding programs to increase the probability of selecting potential commercial genotypes, but this should be balanced with high diversity crosses to avoid the loss of diversity.

  12. Identification of major QTLs underlying tomato spotted wilt virus resistance in peanut cultivar Florida-EP(TM) '113'.

    2016-09-06

    Spotted wilt caused by tomato spotted wilt virus (TSWV) is one of the major peanut (Arachis hypogaea L.) diseases in the southeastern United States. Occurrence, severity, and symptoms of spotted wilt disease are highly variable from season to season, making it difficult to efficiently evaluate breeding populations for resistance. Molecular markers linked to spotted wilt resistance could overcome this problem and allow selection of resistant lines regardless of environmental conditions. Florida-EP(TM) '113' is a spotted wilt resistant cultivar with a significantly lower infection frequency. However, the genetic basis is still unknown. The objective of this study is to map the major quantitative trait loci (QTLs) linked to spotted wilt resistance in Florida-EP(TM) '113'. Among 2,431 SSR markers located across the whole peanut genome screened between the two parental lines, 329 were polymorphic. Those polymorphic markers were used to further genotype a representative set of individuals in a segregating population. Only polymorphic markers on chromosome A01 showed co-segregation between genotype and phenotype. Genotyping by sequencing (GBS) of the representative set of individuals in the segregating population also depicted a strong association between several SNPs on chromosome A01 and the trait, indicating a major QTL on chromosome A01. Therefore marker density was enriched on the A01 chromosome. A linkage map with 23 makers on chromosome A01 was constructed, showing collinearity with the physical map. Combined with phenotypic data, a major QTL flanked by marker AHGS4584 and GM672 was identified on chromosome A01, with up to 22.7 % PVE and 9.0 LOD value. A major QTL controlling the spotted wilt resistance in Florida-EP(TM) '113' was identified. The resistance is most likely contributed by PI 576638, a hirsuta botanical-type line, introduced from Mexico with spotted wilt resistance. The flanking markers of this QTL can be used for further fine mapping and marker

    2003-02-01

    Using 15 simple sequence repeat (SSR) microsatellite DNA loci, we analyzed genetic variation within Cocos nucifera germplasm collections at two locations in south Florida, representing eight cultivars. The loci were also used in a parentage analysis of progeny of the 'Fiji Dwarf' variety at both locations. A total of 67 alleles were detected, with eight the highest number at any one locus. These loci identified 83 of the 110 individual palms. Gene diversity of the 15 loci ranged from 0.778 to 0.223, with a mean of 0.574. 'Fiji Dwarf', 'Malayan Dwarf', 'Green Niño' and 'Red Spicata' cultivars resolve as distinct clusters in a neighbor joining tree using modified Rogers distance, while the tall varieties form two aggregates. The highest gene diversity was found in the tall cultivars (H = 0.583 cumulatively), and the lowest in the 'Malayan Dwarf' (H = 0.202). After the tall coconuts, the 'Fiji Dwarf' was most genetically diverse (H = 0.436), and had the largest number of unique alleles. Genetic identity is highest among the 'Malayan Dwarf' phenotypes, and between the tall varieties. The 'Red Malayan Dwarf' is genetically distinct from the 'Green' and 'Yellow Malayan Dwarf' phenotypes, which cannot be distinguished with the SSR loci used. Off-type 'Malayan Dwarf' phenotypes (putative hybrids with talls) can be identified genotypically. Parentage analyses of 30 'Fiji Dwarf' progeny propagated from five adults surrounded by other cultivars estimate that only 20% of the progeny were out-crossed to the other varieties, while 40-46% were possible selfs. This suggests that a seed-production orchard of the variety maintained at reasonable distance from other varieties, will likely yield only 'Fiji Dwarf' genotypes. Our data are discussed in the context of hypotheses of coconut dissemination around the world.

    Tea (Camellia sinensis L.) leaf contains a large amount of catechins (a group of very active flavonoids) which contribute to major quality attributes of black tea. Based on morphological characters tea plants were classified as Assam, China, and Cambod varieties. The present study is an attempt for biochemical fingerprinting of the tea varieties based on catechin composition in green leaf of cultivars grown in Northeast India. Assam variety cultivars contained the highest level of catechins followed by Cambod and China. The average catechin contents were 231 ± 7 mg g−1, 202 ± 5 mg g−1, and 157 ± 4 mg g−1 of dry weight of green leaf for Assam, Cambod, and China cultivars, respectively. Among the individual catechins the variations in epigallocatechin gallate (EGCG) and epigallocatechin (EGC) were the most prominent among the varieties. High EGC content was found to be a characteristic of Assam variety which was further corroborated through multivariate analysis. PMID:22448135

    Wuchereria bancrofti has shown nocturnal periodicity in India and other endemic countries of the world except pacific regions where non-periodic or diurnal sub-periodic forms have been reported. Presence of sub-periodic form of W. bancrofti in Andaman and Nicobar Islands, India and a case report of sub- periodic form of W. bancrofti from Mysore, India provide basis for exploring the periodicity pattern of microfilaria of W. bancrofti prevalent in Assam, Northeastern region of India. State of Assam has unique geographical location as its Northeastern region shares international boundaries with Nepal, China, Bhutan, Myanmar and Bangladesh. Evolutionary association of W. bancrofti found in Assam is not known and possibility of its link with W. bancrofti form, prevalent in neighbouring countries may not be ruled out. Hence, this study was undertaken to know the microfilarial periodicity of W. bancrofti in Assam. Ten microfilaria positive adult male individuals having moderate to high microfilaraemia were selected. Informed written consent from each participant was obtained. The presence of microfilaria was observed at two hourly intervals over a period of 24 h using 50 μl of finger prick peripheral blood samples. Peripheral blood smears were processed, stained and examined under microscope and microfilaria counts were recorded. Data collected were calculated and analyzed using modified statistical method, and the periodicity curve was prepared. Typical nocturnal periodicity was observed at a peak time of 0003 hrs with a periodicity index of 136.2. Analysis of the data revealed nocturnal periodicity of the W. bancrofti prevalent in the Assam with peak periodicity about one hour ahead of the other states in India. Findings will be helpful in evaluation and monitoring of ongoing MDA programme for elimination of LF in Assam.

    In the northern states, there is hardly any scientific study except road traffic accidents (RTAs) statistics obtained by the Ministry of Home whereas the main way of transportation is by road. There is the increasing load of motor vehicles on the already dilapidated roadways which has resulted in the increasing trend of RTAs in Assam. To find out the prevalence, probable epidemiological factors and morbidity and mortality pattern due to RTAs in Dibrugarh district. Descriptive study was carried out in Dibrugarh district from September 1998 to August 1999 under the department of Community Medicine. The information was collected from Assam Medical College and Hospital and cross checked with the police report. A medical investigation including interview, clinical and radiological investigation was carried out; in case of fatality, post-mortem examination was examined in details. An on the spot investigation was carried out in accessible RTAs to collect the probable epidemiological factors. RTAs affected mainly the people of productive age group which were predominantly male. Majority of the RTAs were single vehicle accidents and half of the victims were passengers. Accident rate was maximum in twilight and winter season demanding high morbidity and mortality. Head and neck, U.limb and L.limb were commonly involved. RTAs is a major public health problem in Assam which needs more scientific study.

    Being one of the most common types of life threatening diseases in Southern Assam, India, the digestive system disorders (DSD) have gained much attention in recent decades. Traditional beliefs and inadequate income of mass population result in the use of alternative phytotherapies to treat the diseases. The present paper documents the medicinal knowledge and utilization of plants for treatment of digestive system disorders in Southern Assam, India by Disease Consensus Index (DCI). It also determines the most suitable plant species used to treat digestive system disorders in the study area. The study was based on ethnomedicinal field survey covering a period of 1 year from 2014-2015. The ethnomedicinal information was collected by using semi-structured questionnaires from different traditional Bengali people having knowledge on medicinal plants. Collected data were analyzed by calculating DCI. During the survey, 29 informants were interviewed and a total of 49 plants under 46 genera belonging to 33 families were listed. Data analysis revealed that Litsea glutinosa, Momordica charantia, Andrographis paniculata, Lawsonia inermis, Cleome viscosa, Psidium guajava, Ageratum conyzoides, Cuscuta reflexa, Cynodon dactylon and Carica papaya are the most prominent plants among the people of Southern Assam for treating DSD. This explorative survey emphasizes the need to preserve and document the traditional healing practices for managing DSD inviting for more imminent scientific research on the plants to determine their efficacy as well as safety. With the help of statistical analysis (DCI), we propose 10 priority plants for DSD in present work. Systematic pharmacological study with these plants may contribute significant result.

    This paper investigates the relationships between welfare and geographical factors derived from remotely sensed satellite data within Assam, India. The pressure that natural resources experience from population growth is a significant barrier to sustainable human development and ecological conservation. Integrating social and geographic data offers the potential to increase our understanding of population-environment relationships. We construct a village welfare index for an extensive area of Assam in Northeast India. Classification and regression tree techniques were used to model the relationships between welfare and geographic conditions derived from remotely sensed data. Geographic metrics accounted for 61% of the variation in the lowest welfare quintile and 57% in the highest welfare quintile. Travel time to market towns, percentage of a village covered with woodland and winter crop were significantly related to welfare. These results support findings in the literature across a range of different developing countries which have used socioeconomic and geographic data derived only from household surveys. Model accuracy is unprecedented considering that the majority of information for the prediction is derived from remotely sensed data. As satellite data can provide continually updated geographic metrics, the results indicate the potential for substantially increasing our understanding of poverty-environment relationships by coupling remotely sensed and socioeconomic datasets. Further studies should be conducted using time series analysis as knowledge of population-environment inter-linkages will be required to help foster more effective policies for sustainable human development and ecological conservation.

    Diphtheria is still a significant child health problem in countries with low immunization coverage. Reports of diphtheria in adult population are also increasing. Here we describe three recent outbreaks of diphtheria in Dibrugarh district, Assam in two consecutive years. The study was undertaken in Assam Medical College & Hospital, Dibrugarh after the diagnosis of two Diphtheria cases in the month of September and October 2015 and another in January 2016. Outbreak investigation was done after defining operational definition and throat swabs were collected from thirty three (33) individuals including three (3) index cases and thirty (30) close contacts. Diagnosis was done by clinical findings, direct microscopy, bacteriological culture and in-house designed multiplex Polymerase Chain Reaction (PCR) of the isolates for the expression of Corynebacterium diphtheriae specific rpoB gene and tox gene. Out of the 10 confirmed cases, 2 and 7 were in the first two outbreaks while only one in the third outbreak respectively. All the cases were of age > 10 years, unimmunized or partially immunized. The overall mortality was 20%. PCR results revealed all the culture positive isolates to be tox gene positive. Diphtheria is a resurgent problem in our region with a significant age shift towards adult. PMID:27630847

    Streptococcus mutans, a gram-positive oral bacterium, has been identified as one of the principal etiological agents of human dental caries. To clarify the nature of the difference anti-biofilm effect against S. mutans between Assam tea from Camellia sinensis var. assamica, partially fermented, and green tea from Camellia sinensis, non-fermented, active agents from the teas were purified. Effects of Assam tea and green tea samples on biofilm were assessed by using the conventional titer plate method and the human saliva-coated hydroxyapatite discs. The purification and identification of inhibitors were performed by using ultrafiltration with centrifugal filter devices and high performance liquid chromatography. Assam tea has stronger biofilm inhibition activity against S. mutans than green tea. A substance of <10kDa in mass in Assam tea had a high concentration of galloylated catechins and a stronger biofilm inhibiting activity than green tea. In contrast, substances >10kDa in mass from green tea included higher concentrations of polysaccharides composed of galacturonic acid, such as pectin, that enhance biofilm formation. The higher concentrations of galloylated catechins in Assam tea may assist in prevention of dental caries, whereas in green tea, this mode of inhibition was likely offset by the presence of pectin. Purification of catechins in partially fermented Assam tea with lower-molecular-weight polysaccharide than pectin may be useful for developing oral care products such as toothpaste and oral care gel pastes.

    Introduction Prevalence of haemoglobinopathies and β-thalassaemia are very high in India but information about its status among the tribals working in the tea gardens of Assam is very less. Aim The present study was carried out to determine the prevalence of haemoglobinopathies and β-thalassaemia among the tribals working in the tea gardens of Assam. Materials and Methods A total 1204 samples from the tribals working in tea gardens of Assam were analysed for both Complete Blood Count (CBC) and High Pressure Liquid Chromatography (HPLC) for detection of haemoglobinopathies and β-thalassaemia. Results This study showed that the prevalence of sickle cell anaemia and β-thalassaemia were very high among this population. Our results indicated a higher prevalence of β-thalassaemia (3.07%) among the Munda ethnic group and higher prevalence of sickle cell anaemia (4.73%) among the Lohar ethnic group. This was the first study to report the presence of HbE among the tribals working in the tea gardens of Assam. Conclusion Based on the present findings, sickle cell anaemia and β-thalassaemia were major health problem for the tribals working in the tea gardens of Assam. Proper diagnostic facilities for haemoglobinopathy and thalassaemia should be established in these areas, including establishment of haemoglobinopathy and thalassaemia database collection, haematological analysis laboratories, genetic counselling clinics, prenatal diagnosis centres and neonatal screening centres.

    Talukdar, Naba Kumar

    The study deals with various aspects of flood hazard in Barpeta district of Assam, Northeast India. It is broadly confined to three basic themes - general perspectives, environmental perspectives and flood hazard mitigation. The first theme includes the study on flow characteristics of the major rivers of the district during rainy season and zoning of flood prone areas. The second theme deals with some environmental aspects of floods in the district, such as river water quality during floods, effects of floods on soil quality, human health and socioeconomic losses. Flood mitigation study includes discussion on measures adopted for flood mitigation in the district and suggested management strategies. The study covers a wide range of database generated from both primary and secondary sources. Primary data on relevant parameters of soil and water are generated by using proper sampling procedures and standard laboratory methods. Suitable graphical and statistical methods have been used to analyze and interpret different kinds of data. All the relevant data and surveyed information on the perspective of the flood plain dwellers of the district are integrated together in formulating flood management strategies. The Barpeta District of Assam covers an area of 3245 sq. km. comprising 4.2% of the total area of the state. The district has fascinating diversified landscape sloping from north to south which includes highlands covered by forests, plain fertile lands suitable for agricultural activities and low lying areas containing-water bodies and swamps. Flood is a perennial problem and all kinds of common flood damages prevail in the district. Floods cause large-scale damages to the socio-economic life of the people as well as to the ecology and environment of the district to a certain extent. The rivers Manas, Beki, Pahumara and Kaldia and their tributaries, which emerge from Eastern Himalaya, create flood havocs in the district. During monsoon period, these rivers are

    2010-07-01

    The primary objective of this study is to present a statistically significant water quality database of Dhemaji district, Assam (India) with special reference to pH, fluoride, nitrate, arsenic, iron, sodium and potassium. 25 water samples collected from different locations of five development blocks in Dhemaji district have been studied separately. The implications presented are based on statistical analyses of the raw data. Normal distribution statistics and reliability analysis (correlation and covariance matrix) have been employed to find out the distribution pattern, localisation of data, and other related information. Statistical observations show that all the parameters under investigation exhibit non uniform distribution with a long asymmetric tail either on the right or left side of the median. The width of the third quartile was consistently found to be more than the second quartile for each parameter. Differences among mean, mode and median, significant skewness and kurtosis value indicate that the distribution of various water quality parameters in the study area is widely off normal. Thus, the intrinsic water quality is not encouraging due to unsymmetrical distribution of various water quality parameters in the study area.

    An investigation on the water quality and aquatic insect community of an oxbow lake (Phulbari anua) of south Assam, North-East India was carried out during February to April, 2010. Aquatic insect community of the oxbow lake was represented by 9 species belonging to 9 families and 4 orders during the study period. Order Ephemeroptera and Hemiptera were found to be dominant. Record of 5 species and 5 families from the order Hemiptera showed that this is the largest order in terms of aquatic insect diversity of the lake. Computation of dominance status of different species of aquatic insects of the lake based on Engelmann's Scale revealed that Anisops lundbladiana and Cloeon sp. were eudominant in the system. The Shannon- Weiner's Diversity Index (H') and Shannon evenness values (J') were found to range from 0.3-0.69 and 0.53 -0.97, respectively indicating perturbation of the system. Again in terms of physico-chemical properties of water the lake is in a satisfactory condition where all the parameters are well within the range of IS 10500. The DO values were found to range from 6.8 to 14.8 mgl(-1). Free CO2 fluctuated from 1 to 4.98 mgl(-1) and nitrate in water ranged from 0.4 to 2.1 mgl(-1). Margalef's water quality index values of most of the samplings also indicated clean water condition of the lake. Correlation coefficient analyses of the environmental variables, aquatic insect diversity and density of the lake revealed that aquatic insect diversity of the lake is mainly governed by dissolved oxygen, nitrate, and free carbon dioxide.

    Similarities in the 3D patterns of amino acid side chains can provide insights into their function despite the absence of any detectable sequence or fold similarities. Search for protein sites (SPRITE) and amino acid pattern search for substructures and motifs (ASSAM) are graph theoretical programs that can search for 3D amino side chain matches in protein structures, by representing the amino acid side chains as pseudo-atoms. The geometric relationship of the pseudo-atoms to each other as a pattern can be represented as a labeled graph where the pseudo-atoms are the graph's nodes while the edges are the inter-pseudo-atomic distances. Both programs require the input file to be in the PDB format. The objective of using SPRITE is to identify matches of side chains in a query structure to patterns with characterized function. In contrast, a 3D pattern of interest can be searched for existing occurrences in available PDB structures using ASSAM. Both programs are freely accessible without any login requirement. SPRITE is available at http://mfrlab.org/grafss/sprite/ while ASSAM can be accessed at http://mfrlab.org/grafss/assam/. PMID:22573174

    Aim: To determine the prevalence and diversity of Eimeria spp. in dairy cattle present in and around Guwahati, Kamrup district, Assam, India. Materials and Methods: A total of 2339 fecal samples of calves (535), heifer (641) and adult (1163) cattle were screened for 1 year present in and around Guwahati, Assam for detection of Eimeria oocysts by flotation techniques. Sporulation of the oocyst was done in 2.5% potassium dichromate solution for identification of the Eimeria species. Results: Examination of fecal samples revealed an overall prevalence of 11.97% Eimeria infection in dairy cattle of Guwahati, Assam. Age-wise, 33.2%, 45.4%, and 21.4% infections were recorded in calves (<1 year), heifer (1-3 years) and adult (>3 years) cattle, respectively. Season-wise, infection was recorded highest during post-monsoon (16.29%), followed by monsoon (15%), winter (9.44%), and pre-monsoon (7.49%) season. Seven species of Eimeria were recorded viz. Eimeria bovis, Eimeria zuernii, Eimeria subspherica, Eimeria bukidnonensis, Eimeria auburnensis, Eimeria ellipsoidalis and Eimeria alabamensis. The oocyst count per gram of feces ranged from 50 to 1500 in infected cattle. Conclusion: This study indicates that there is the prevalence of seven species of Eimeria in dairy cattle of Guwahati, Assam and mostly prevalent during the post-monsoon season. PMID:27047181

  14. Surrogate mother – praiseworthy or stigmatized: a qualitative study on perceptions of surrogacy in Assam, India

    Arvidsson, Anna; Vauquline, Polly; Johnsdotter, Sara; Essén, Birgitta

    2017-01-01

    ABSTRACT Background: Surrogacy is a reproductive practice that has been strongly marketed in India as a solution for childless couples. As a result, the number of surrogacy clinics is increasing. Meanwhile, a global discourse on surrogacy, originating from a Western perspective, has characterized surrogacy as being exploitative of women in low-income settings, where poverty drives them to become surrogate mothers. Objective: This study explored perspectives on surrogacy from men and women in Assam, an Indian state known to be a low-income setting. Surrogacy arrangements in Assam are still uncommon. It can be expected that the dominant global discourses on surrogacy will be unfamiliar to the general population, and the objective was also to position the results within the divergent global discourses of surrogacy. Methods: In order to explore local views on surrogacy, we conducted individual interviews and focus group discussions with people from various socioeconomic groups in Assam. Results: Our findings reveal that people in Assam perceive surrogacy as a good option for a childless couple, as it would result in a child who is a ‘blood’ relation – something highly desirable for sociocultural reasons. However, the part played by the surrogate mother complicates local views on surrogacy. Most people consider payment to the surrogate mother contrary to societal norms. A surrogate mother is also often judged in a moral light, either as a ‘bad mother’ for selling her child, or as a ‘noble woman’ who has helped a childless couple and deserves payment for her services. Conclusions: In order to decrease the stigmatization of women, a regulatory policy is needed that will take into account the complex understandings of surrogacy and perceptions of surrogate mothers in Indian society. In policy, the possible effect of the dominant exploitation discourse needs to be modulated by local understandings of this reproduction method. PMID:28604252

    Assam is the highest tea producer state in the country. There is scarcity of reliable information on health and nutritional status among tea garden population of Assam to enable initiating public health response to their health needs. To describe health problems and nutritional status among tea garden population of Assam. Community-based cross-sectional survey in eight randomly selected tea gardens of Dibrugarh district of Assam. Socio-demographic and behavioral characteristics of participants were recorded. Health problems and nutritional status were assessed through medical examination, evaluation of medical records, anthropometry and laboratory investigations. Percentage prevalence; Chi-square test was applied wherever applicable. Out of 4,016 participants, 1,863 were male and 2,153 were female. They were mostly illiterate and nearly 52.9% (1,197 of 2,264) of adults were manual workers in the garden. Alcohol and oral tobacco use were common. Prevalence of underweight among children was 59.9% (357 of 596) and thinness among adults was 69.9% (1,213 of 1,735). Anemia was widespread. Worm infection (65.4%, 217 of 332); skin problems; respiratory infections, including tuberculosis; filariasis were present in a significant way. Children suffered more in various diseases. Major noncommunicable diseases like hypertension, stroke were emerging in the community and were associated with modifiable risk factors like alcohol and tobacco use. Health status of the population can be ameliorated through better hygienic practices, environmental sanitation, creating health awareness, nutritional intervention and overall improvement of socioeconomic conditions of the population.

    Water soluble polysaccharides are most effective oncotic agents which are used for treatment of intravascular volume deficiency. Nowadays, they are used as basic material for plasma volume expander. Plasma volume expander based on starch has lower tendency to remain in any major organ of body in comparison to other plasma volume expander. Branched component of starch amylopectin is very similar in structure to glycogen, the reserve polysaccharides of animal; for all this reason starch is compatible with body tissues. Physicochemical properties of raw starch and amylopectin, isolated from Assam Bora rice were characterized for use as plasma volume expander. Characterization involves the determination of ash value, weight average molecular mass, viscosity and resistance towards enzymatic (amylase) hydrolysis. Amylose content was almost negligible. The X-ray diffraction pattern of Assam Bora rice starch was typically A type. High degree of crystallinity of Assam Bora rice starch reflects its resistance towards enzymatic hydrolysis which is of therapeutic advantage for using it as a plasma volume expander.

  19. Effect of flaring of natural gas in oil fields of Assam on rice cultivation.

    Sharma, K K; Hazarika, S; Kalita, B; Sharma, B

    2011-07-01

    Assam (India) is endowed with natural resources like oil, coal and natural gas. The crude oil, one of the most precious natural resources, is found in the districts of upper Assam. During the process of extraction of crude oil, low-pressure natural gas is burnt in the air. Most of the oil wells in upper Assam are located near rice fields and therefore, rice crop grown near the oil wells is exposed to light uninterruptedly causing grain sterility resulting significant loss in grain yield. To identify promising varieties for these areas, we studied the effect of flare on rice varieties with different photoperiod sensitivity. The high light intensity and increased light hours were the factors responsible for substantial loss in grain yield near the flare resulting from delay in flower initiation, reduction of panicle length, having less number of grains per panicle and more grain sterility. To prevent significant loss in yield, photoperiod-sensitive traditional and improved rice varieties should not be grown up to the distance of 80 and 100 m, respectively from the boundary wall of the flare pit. Modern weakly-photoperiod sensitive varieties like Ranjti and Mahsuri can be grown 40 m away from the wall while modern photoperiod insensitive variety like Jaya, can be cultivated 20 m away from the wall without significant loss in yield.

    This study investigated the osteon structure of adult humans and Assam macaques, which served as a nonhuman primate model, to find an adequate key for species identification. Samples of compact bone from humans (n=5) and Assam macaques (n=5) - including humerus (n=20), radius (n=20), ulna (n=20), femur (n=20), tibia (n=20) and fibula (n=20) - were processed using conventional histological techniques. 100 secondary osteons from each sample were evaluated under light microscopy. Parameter measurements included: diameter, perimeter and area of Haversian canal and osteon; distance between centers of Haversian canals; and ratio between diameter of Haversian canal and osteon. Four parameters, including diameters and areas of Haversian canal and osteon, demonstrated significantly higher (P<0.05) values in humans than in Assam macaques. Therefore, compact bone microstructure could thus be used as a potential tool to differentiate human and nonhuman primates. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Belonolaimus longicaudatus and Helicotylenchus spp. are damaging nematode species on bermudagrass (Cynodon spp.) and seashore paspalum (Paspalum vaginatum) in sandy soils of the southeastern United States. Eight bermudagrass and three seashore paspalum cultivars were tested for responses to both nematode species in field plots for two years in Florida. Soil samples were taken every three months and nematode population densities in soil were quantified. Turfgrass aboveground health was evaluated throughout the growing season. Results showed that all bermudagrass cultivars, except TifSport, were good hosts for B. longicaudatus, and all seashore paspalum cultivars were good hosts for H. pseudorobustus. Overall, bermudagrass was a better host for B. longicaudatus while seashore paspalum was a better host for H. pseudorobustus. TifSport bermudagrass and SeaDwarf seashore paspalum cultivars supported the lowest population densities of B. longicaudatus. Seashore paspalum had a higher percent green cover than bermudagrass in the nematode-infested field. Nematode intolerant cultivars were identified. PMID:23430148

    Japanese encephalitis (JE) outbreaks are common in Assam, northeastern State of India. Information on resistance in known JE vectors in the affected area is important for effective control measures. This study was undertaken to determine the species abundance of JE vectors endemic to Sibsagar district of Assam, and their susceptibility against DDT and deltamethrin. Adult mosquitoes were collected using CDC light trap and aspirators from human dwellings from 13 endemic villages falling under three Primary Health Centres. Collected mosquitoes were identified and unfed female mosquitoes were used for DDT and deltamethrin sensitivity bioassay. The bioassay was performed following WHO protocol using standard susceptibility test kit. Knockdown time (KDT) was monitored at every 10 minutes intervals, whereas mortalities were recorded 24 h post-exposure. Vector density and resistance status were mapped using geographic information system (GIS) technique. A total of 7655 mosquitoes were sampled under three genera, i.e. Anopheles, Culex and Mansonia, and nine species, the JE vector Cx. vishnui group (31.78%) was the most predominant species, followed by Ma. uniformis (16.81%) and Ma. indiana (16.45%). All vector species were suspected to be resistant to DDT and sensitive to deltamethrin, except Ma. indiana, which was suspected to deltamethrin resistant. The KDT50 and KDT95 values of vector mosquitoes for DDT were significantly higher as compared to deltamethrin. The probit model used to estimate KDT50 and KDT95 values did not display normal distribution of percentage knockdown with time for all the vectors tested for DDT and deltamethrin, except for Ma. indiana for deltamethrin assay and Cx. gelidus for the DDT assay. Differences in insecticide resistance status were observed between insecticides and vector species. The results of this study provided baseline data on insecticide resistance in known JE vectors of Sibsagar, Assam. The maps generated may allow better

    Tea production has a measurable impact upon millions of people's livelihoods in northeast India. The region is experiencing changes in climate characteristics which are placing added pressure on the tea industry for sustaining livelihoods. To increase understanding of the role of tea within the Assam landscape, this research has engaged with multiple local tea-producing stakeholders. Approximately 65% of Assam's tea is produced in large plantations, with the remaining 35% produced in smallholdings. Questionnaires were used to obtain information on land management practices operationalised by plantation managers and smallholders. Focus group sessions using the Delphi technique were conducted with tea workers (labourers for the plantations) to ascertain the level of importance of the tea sector to sustaining their livelihoods. Questionnaires and focus group surveys also attempted to establish stakeholder understanding of climate change. Data were analysed using spatial statistics to investigate intra- and inter-region variation in responses. Focus group responses were categorised to determine the livelihood asset base available to tea workers within plantations, with patterns of (dis)similarity observed spatially. Results indicate that land management practices (e.g. fertiliser and pesticide application), tea processing methods (e.g. onsite factory and energy generation), and social provisions for tea workers (e.g. sanitation and education facilities) varied greatly across the main tea growing regions of Assam. Tea workers listed numerous environmental and social factors as important for sustaining livelihoods, with the top ranked factors similar across some plantations (e.g. drinking water availability and access). Plantation managers are highly concerned with how climate conditions are affecting tea production, and although workers were aware of climate change issues in some plantations, socioeconomic conditions seemed of more pressing concern to their livelihoods.

    A new measure of diversification index is proposed taking the correlation structures of the shares into consideration. This index is a generalization of the Herfindahl-Hirschman Index (HHI) proposed in the context of concentration in industries. When this index is applied in the crop production along with other related data in Assam, India, it is seen that many of the interrelations are changed from that of found by HHI. The analysis helps us to plan for improvement of crop patterns in a region prudently.

    A fossil leaf resembling Poeciloneuron indicum Bedd. (Clusiaceae) is described from the Late Oligocene (Chattian 28.4-23 Myr) sediments of Assam. The modern analogue is endemic to the Western Ghats which is situated in the same palaeolatitude. Its presence, along with other known fossil records, indicates that the seasonality in temperature was less pronounced and CMMT (cold month mean temperature) was not less than 18°C with plenty of rainfall, in the region during the period of deposition. The study also indicates that the plant phenology is sensitive towards climate change. The present study is in congruence with the global data.

    Preliminary random and mass blood surveys undertaken between 2000-0100 h in a tea garden of Upper Assam revealed more than 8 per cent positivity for microfilaria (mf) of Wuchereria bancrofti. The mf carriers were considerably high among males (73) as compared to females (48). Culex quinquefasciatus was incriminated as a vector with man hour density of 68.5 in human dwellings (indoors). The detection of mf in children who had never moved from the area and filaria larvae in vector mosquitoes collected from human dwellings indicate that indigenous transmission is going on in the garden and that filariasis has become a local health problem.

    Introduction Japanese encephalitis (JE) is a major cause of high morbidity and mortality in several states across India. However, in 2014, a sharp rise was observed in the number of cases of JE in north-eastern Assam state, and 51% of the total cases of JE in India were reported from the Assam in the same year. In this regard, a study was conducted to evaluate the knowledge and attitudes of healthcare workers in Darrang, a district of Assam highly affected by JE. Methods A cross sectional study was conducted for 2 months among HCWs in the major district hospital of Darrang, Assam. A pre-tested, self-administered questionnaire was used to collect data from the participants. Convenience sampling approach was used to collect data from different departments of the hospitals. Descriptive and logistic regression analyses were used to express the results. Results The knowledge of HCWs regarding JE was poor with a mean knowledge score of 11.02±2.39 (out of 17), while their attitudes were positive with a mean attitudes score of 43.16± 2.47 (ranging from 13 to 52). Overall, 40.4% and 74.3% of participants demonstrated good knowledge and positive attitudes respectively. Cut-off score for good knowledge and positive attitudes toward JE was set as ≥12 and >40 respectively. Older participants (40–49 years) and experienced workers (>10 years) were significantly associated with good knowledge as compared to their referent group (p<0.05), while knowledge of nurses and other orderlies were significantly lower than physicians (p<0.01). Similar factors were associated with the positive attitudes of the participants with the exception of experience. Television was the major source of information regarding JE reported by HCWs (79%). Conclusion Although the knowledge was not optimized, HCWs exhibited positive attitudes towards JE. Future research is required to design, implement and evaluate interventions to improve the knowledge of JE among HCWs. PMID:26296212

    Strawberry (Fragaria × ananassa) is an economically important soft fruit crop with polyploid genome which makes the breeding of new cultivars difficult. Simple and efficient method for transformation and regeneration is required for cultivars improvement in strawberry. In the present study, adventitious shoot regeneration has been investigated in three cultivated strawberry plants, i.e., Festival, Sweet Charly and Florida via direct organogenesis using the in vitro juvenile leaves as explants. Explants were collected after sub-culturing on a propagation medium composed of MS supplemented with 0.5 mg/l BA; 0.1 mg/l GA3 and 0.1 mg/l IBA. To select the suitable organogenesis, the explants of the three cultivars were cultured on MS medium supplemented with different concentrations of TDZ (1, 2, 3, and 4 mg/l), then incubated at a temperature of 22 °C ± 2. Medium containing 2 mg/l TDZ revealed the best regeneration efficiency with the three cultivars (72% for Festival, and 73% for Sweet Charly and Florida). After 4 weeks, the produced shoots were cultured on MS medium with different concentrations of BA and Kin to enhance shoot elongation. Results showed that the medium containing 1.5 mg/l BA and 0.5 mg/l Kin revealed highest elongation efficiency (88% and 94%) for Festival and Sweet Charly, respectively. On the other hand, medium containing 1.5 mg/l BA and 0.1 mg/l Kin showed highest elongation efficiency (90%) in Florida. Elongated shoots were successfully rooted on MS medium containing 1.5 mg/l NAA. Furthermore, transformation of the two cultivars, Festival and Sweet Charly, has been established via Agrobacterium strain LBA44404 containing the plasmid pISV2678 with gus-intron and bar genes. Three days post co-cultivation, GUS activity was screening using the histochemical assay. The results showed 16% and 18% of the tested plant materials has changed into blue color for Festival and Sweet Charly, respectively. Out of 120 explants only 13 shoots were developed on

    Effects of yard waste compost and maize (Zea mays) cultivar on population densities of plant-parasitic nematodes were examined in four experiments in north Florida. In one experiment, eight maize cultivars were evaluated; the other three experiments involved split-plot designs with compost treatments as main plots and maize cultivars as subplots. The three compost treatments used in these experiments were: 269 mt/ha of a yard-waste compost applied to the soil surface as a mulch, 269 mt/ha of compost incolporated into the soil, and an unamended control. No interactions between compost treatment and cultivar occurred in any experiment. Effects of compost treatment on Mesocriconema spp., Meloidogyne incognita, and Pratylenchus spp. were inconsistent, whereas significant effects of compost on population densities of Paratrichodorus minor were found on four of six sampling occasions. Cultivar affected final population densities (Pf) of M. incognita. In two tests, Pf of M. incognita on a Florida subtropical experimental hybrid (Howard III) were only 36% and 23% of Pf on the standard tropical hybrid (Pioneer Brand X304C). In an integrated approach to management of nematodes in maize, the effects of compost amendment and culfivar choice acted independently. Apparently, cultivar choice is more important than amendment with yard waste compost for management of M. incognita population levels in a maize rotation crop. PMID:19274277

    Outbreaks of contagious ecthyma (caused by a Parapox virus) in goats were investigated in 6 districts of Assam, a north eastern state of India. Diagnosis of the disease was carried out employing both standard virological as well as molecular methods. Four representative isolates from different places were selected for phylogenetic analysis. The major envelop protein (B2L) of Orf virus was targeted for molecular analysis. The sequencing and phylogenetic analysis of the selected sequences at nucleotide level revealed that the Orf virus isolates were closely related to each other (97.6-100 %) and showed highest similarity to the Orf virus isolate 82/04 (98.4 %), reported from Shahjahanpur, India. The data will provide an insight in transmission of the virus from northern to North eastern part of the country.

    Pregnancy is a critical time in the course of life, having both health and social impacts for individuals, family, and society. The prevalence of undernutrition among pregnant women in a rural area of Assam, India, was examined using anthropometric and biochemical assessments. Key socioeconomic factors that affect nutritional status were examined. A cross-sectional study with a sample of 285 women from all three trimesters was done. The results found that 48% of the women were below normal for Body Mass Index (BMI), indicating a high level of undernutrition. The age of the mother and husband's occupation showed a strong positive correlation with BMI, while family size and income level showed a negative correlation. The results of the biochemical analysis showed that 62% of the women were anemic, and copper and zinc levels were 29% and 12% below normal levels, respectively. The study findings indicate that undernutrition is far higher than national and global standards.

This study was conducted to assess prevalence and level of modifiable cardiovascular risk factors among tea-garden and general population in Dibrugarh, Assam. A community-based cross-sectional study using the World Health Organization's (WHO) Stepwise methodology was conducted in Dibrugarh District of Assam. A multistep random sampling was done to include adults aged 35 years and above, with an intended equal sampling from tea-garden and general population. INTERHEART modifiable non-laboratory based risk score was estimated. Salt consumption was estimated using questionnaire-based methods in both subgroups. A total of 2826 individuals participated in the study (1231 [43.6%] tea-garden workers; 1595 [56.4%] general population). Tobacco consumption was higher in tea-garden workers as compared with general population (85.2% vs. 41.7% (p < 0.0001). Mean daily per-capita salt consumption was also significantly higher among tea-garden workers (29.60 vs. 22.89 g, p = 0.0001). Overall prevalence of hypertension was similar (44.4% vs. 45.2%), but among those who had hypertension, prevalence of undiagnosed hypertension was higher in tea-garden workers (82.8% vs. 74.4%, p < 0.0001). Tea-garden workers had lower BMI, were more physically active, and had a lower prevalence of diabetes mellitus and metabolic syndrome. Their INTERHEART modifiable risk score was also lower (1.44 [2.5] vs. 1.79 [2.8], p = 0.001). High prevalence of modifiable risk factors like tobacco consumption, high salt intake and high prevalence of hypertension indicates the need for early implementation of preventive actions in this population.

    Aim: To know the prevalence of gastrointestinal nematode larvae (L3) in the grazing land of cattle in Guwahati, Kamrup district, Assam. Materials and Methods: Pastures were collected and examined for the presence of nematode larvae (L3) from six localities of Guwahati at monthly interval from August 2012 to July 2013. The counted larvae were then expressed as per kg dry matter of herbage (L3/kg DM). Results: Examination of pastures revealed presence of nematode larvae (L3) in pastures throughout the year which varied from 4.5 L3/kg DM in January to a maximum of 106.33 L3/kg DM in August. The L3 of Haemonchus contortus, Trichostrongylus spp., Oesophagostomum spp., Cooperia spp., and Mecistocirrus spp. were recovered from pastures. The average pasture larval burden (PLB) was 34.75±3.48 L3/kg DM. Season-wise PLB revealed the presence of 23.89±3.01, 67.54±5.41, 26.67±1.92, and 7.28±0.89 L3/kg DM during pre-monsoon, monsoon, post-monsoon, and winter seasons, respectively. Monsoon season has significant (p<0.05) effect on PLB. However, analysis of variance of different locations with respect to season revealed that there was no significant difference but season-wise it was highly significant (p<0.01). Pearson correlation of environmental variables (temperature, relative humidity, and rainfall) with PLB revealed correlation was statistically significant with rainfall (p<0.05). Conclusion: This study reveals the presence of five nematode larvae (L3) in the pastures of Guwahati, Assam throughout the year, statistically significant during monsoon season. PMID:28096603

    Cancer of the oesophagus is the most commonly diagnosed cancer in males in Assam, in north-eastern India, and ranks second for females. The chewing of betel nut, with or without tobacco and prepared in various ways, is a common practice in the region and a case-control study has been designed to study the pattern of risk associated with different ways of preparing and chewing the nuts. 358 newly diagnosed male patients and 144 female have been interviewed together with 2 control subjects for each case chosen at random from among the attendants who accompanied patients to hospital. There were significant trends in risk ratios associated with the frequency of chewing each day, with the duration of chewing in years and with the age at which the habit was started that were apparent for both males and females and which remained significant after allowance was made for other known risk factors, notably tobacco smoking and alcohol consumption. The adjusted ratios, in comparison with non-chewers, were 13.3 M and 5.7 F for chewing more than 20 times a day, 10.6 M and 7.2 F for persons who had chewed for more than 20 years and 10.3 M and 5.3 F for those who had started before the age of 20. Among the different combinations of ingredients that were chewed the adjusted odds ratios were highest for those who had been using fermented betel nut with any form of tobacco (7.1 M and 3.6 F). The risk associated with tobacco smoking and alcohol consumption, which are high in some parts of the world, were less in Assam than those associated with the chewing of betel nut.

    Aim: The aim of the present study was to investigate the presence of Theileria in blood samples of crossbred and indigenous adult cows raised under unorganized small scale farming system in a Babesia and Anaplasma endemic geographical area from Assam, India and to see its transmission through Rhipicephalus (Boophilus) microplus ticks. Materials and Methods: For the present study, 57 clinical cases of cattle suspected to be of hemoparasitic infections were taken into consideration. The parasites were identified based on morphology in giemsa stained blood smear followed by polymerase chain reaction (PCR). Sera samples were tested for T. annulata antibodies in plate and Dot-ELISA. PCR was also conducted in eggs of Rhipicephalus (Boophilus) microplus tick collected from a Theileria orientalis positive animal. Results: PCR amplified 1124, 776, and 160 bp DNA fragments of B. bigemina (64.91%), T. orientalis (21.05%) and A. marginale (14.03%), respectively. This assay further conducted in 12 T. orientalis positive blood samples with primers of Buffeli, Chitose, and Ikeda variants of T. orientalis showed 3 samples positive to Ikeda type and none for Buffeli and Chitose. Babesia bovis and Theileria annulata specific primers also did not amplify any fragment during the PCR assay of the blood samples. Further, all sera samples tested negative to T. annulata antibodies in Plate and Dot-ELISA. PCR conducted in eggs of R (B).microplus tick collected from a T. orientalis positive animal revealed presence of the parasite DNA. Gradual improvement in physical condition leading to complete recovery in 10 out of 12 T. orientalis infected clinical cases treated with buparvaquone(at 2.5mg/kg.b.wt I/M) was the feedback obtained from field veterinarians and the cattle owners. Conclusion: The present investigation represents the first report of occurrence of T. orientalis in cattle of Assam with involvement of pathogenic Ikeda strain in clinical outbreaks and its possible natural

    Low birth weight (LBW) infants suffer more episodes of common childhood diseases and the spells of illness are more prolonged and serious. Longitudinal studies are useful to observe the health and disease pattern of LBW babies over time. This study was carried out in rural areas of Assam to assess the morbidity pattern of LBW babies during their first 6 months of life and to compare them with normal birth weight (NBW) counterparts. Total 30 LBW babies (0-2 months) and equal numbers of NBW babies from three subcenters under Boko Primary Health Centre of Assam were followed up in monthly intervals till 6 months of age in a prospective fashion. More than two thirds of LBW babies (77%) were suffering from moderate or severe under-nutrition during the follow up. Acute respiratory tract infection (ARI) was the predominant morbidity suffered by LBW infants. The other illnesses suffered by the LBW infants during the follow up were diarrhea, skin disorders, fever and ear disorders. LBW infants had more episodes of hospitalization (65%) than the NBW infants (35%). Incidence rate of episodes of morbidity was found to be higher among those LBW infants who remained underweight at 6 months of age (Incidence rate of 49.3 per 100 infant months) and those who were not exclusively breast fed till 6 months of age (Incidence rate of 66.7 per 100 infant months). The study revealed that during the follow up, incidence of morbidities were higher among the LBW babies compared to NBW babies. It was also observed that ARI was the predominant morbidity in the LBW infants during first 6 months of age.

    2016-01-01

    Introduction: Chronic noncommunicable diseases (NCDs) including cardiovascular diseases (CVDs) are the leading cause of death in the world, and their incidence is rising rapidly due to increasing rates of risk factors such as hypertension, dyslipidemia, diabetes, obesity, physical inactivity, and tobacco use. These risk factors track from childhood to adulthood, and their distribution varies among males and females; hence, there is a need to determine risk factor prevalence among adolescent age group so as to plan preventive strategies. Objective: To determine the distribution of risk factors of CVDs amongst high school boys and girls of urban Dibrugarh, Assam. Subjects and Methods: A cross-sectional study was conducted from October 2012 to June 2013 in the schools of urban Dibrugarh, Assam wherein data was collected from 1000 students of Class 8–10 using multistage random sampling and risk factors were assessed using WHO steps methodology. Statistical Analysis: Statistical analysis was done using SPSS 16 software and test of differences used were Chi-square test and t-test. Results: The prevalence of ever tobacco use was 32.3% among boys and 6.6% among girls (P < 0.001) while ever alcohol use was reported by 11.9% boys and 1% girls (P < 0.001). Prevalence of overweight and hypertension was found to be higher among girls (11.7% and 24.1%) as compared to boys (6.8% and 18.1%). Prevalence of hypercholesterolemia was higher among boys while high triglycerides levels were more prevalent among girls. Conclusion: The study revealed a high prevalence of various risk factors among boys and girls. There is a need to reduce the risk factor prevalence of CVD among this group of the population to address the future epidemic of NCD. Different health promotional activities need to be implemented to target boys and girls as the risk factor distribution among these groups is different. PMID:27453853

    The emergence of antimalarial drug resistance malaria parasite is widespread in North eastern region of India. During January 2012-December 2013, we conducted active surveillance for detection of antifolate resistance-associated genetic polymorphisms in Plasmodium falciparum malaria parasite from different malaria endemic areas of Assam. A total of 281 field samples were collected from suspected malaria patients of which 106 malaria P. falciparum positive cases were detected in microscopic slide examination. A nested PCR was done for amplification of a 648 bp portion of the dhfr gene and 710 bp portion of the dhps gene. Mutation analysis revealed existence of three different haplotypes of the P. falciparum dhfr gene of which ANRNI was highly prevalent (90%). Triple mutant haplotypes AIRNI (N51I+C59R+S108N) of the dhfr gene associated with pyrimethamine resistance were prevalent in Chirang district of Assam. Whereas, dhps mutation study revealed that triple mutant haplotype AGEAA (S436A+A437G+K540E) associated with Sulphadoxine resistance was found among 26% of P. falciparum field isolates. However, P. falciparum dhfr-dhps two locus mutation analysis showed that there were a total of nine dhfr-dhps genotypes. It was noticed that 93.62% (88/94) isolates had mutations in the sequences of both enzymes, which is an indication of prevalence of high grade of Sulphadoxine - pyrimethamine resistance in P. falciparum malaria parasites in Assam.

    Aim: The objective of this study was to screen the prevalence of contagious ecthyma (CE) among the goat population of Assam owing to its high prevalence rate. Materials and Methods: In this study, a total of 231 serum samples were collected from 12 districts of Assam during September 2013 to July 2014. The serum samples were tested for the presence of antibodies against Orf virus (ORFV) by indirect enzyme-linked immunosorbent assay (ELISA). Indirect ELISA was standardized using purified Orf reference virus produced in bulk in primary lamb testes cells. Results: Studies on seroprevalence showed 76.62% of goats were seropositive. The total number of animals were divided into different age groups starting from 0-2 months, 2-4 months, 4-6 months, and above 8 months and accordingly highest prevalence of antibodies against ORFV was recorded in the age-group above 8 months of age. Significantly, lower rates of infection were observed in goats of age group 2-4 months. This study recorded that seropositivity from naturally infected animals and in contact apparently healthy animals to be 53.67% and 46.32%, respectively. Conclusion: The results indicated that CE is a prevalent infection in goats of Assam, and the healthy population is at increased risk of infection. PMID:27733808

    Cholera is often caused when drinking water is contaminated through environmental sources. In recent years, the drastic cholera epidemics in Odisha (2007) and Haiti (2010) were associated with natural disasters (flood and Earthquake). Almost every year the state of Assam India witnesses flood in Brahamputra River valley during reversal of wind system (monsoon). This is often followed by outbreak of diarrheal diseases including cholera. Beside the incidence of cholera outbreaks, there is lack of experimental evidence for prevalence of the bacterium in aquatic environment and its association with cholera during/after flood in the state. A molecular surveillance during 2012-14 was carried out to study prevalence, strain differentiation, and clonality of Vibrio cholerae in inland aquatic reservoirs flooded by Brahamputra River in Assam. Water samples were collected, filtered, enriched in alkaline peptone water followed by selective culturing on thiosulfate bile salt sucrose agar. Environmental isolates were identified as V. cholerae, based on biochemical assays followed by sero-grouping and detailed molecular characterization. The incidence of the presence of the bacterium in potable water sources was higher after flood. Except one O1 isolate, all of the strains were broadly grouped under non-O1/non-O139 whereas some of them did have cholera toxin (CT). Surprisingly, we have noticed Haitian ctxB in two non-O1/non-O139 strains. MLST analyses based on pyrH, recA and rpoA genes revealed clonality in the environmental strains. The isolates showed varying degree of antimicrobial resistance including tetracycline and ciprofloxacin. The strains harbored the genetic elements SXT constins and integrons responsible for multidrug resistance. Genetic characterization is useful as phenotypic characters alone have proven to be unsatisfactory for strain discrimination. An assurance to safe drinking water, sanitation and monitoring of the aquatic reservoirs is of utmost importance for

    Aqueous leaching of high sulfur sub-bituminous coals from Ledo and Baragolai collieries of Makum coal fields, in Assam, India, has been investigated with respect to time at different temperatures. Leaching at 25{sup o}C up to 120 h showed that the physicochemical characteristics viz., conductivity, acidity, TDS, and SO{sub 4}-2 ions, increase with the increase in time of leaching. The generation of highly acidic leachates at 1-1.5 h (pH 2.5) and 2 h (pH 3.1) for Ledo and Baragolai coals was observed, respectively. However, it remains stable up to 120 h. The concentration of major, minor, and trace elements and their mobility along with the loss of pyritic sulfur or depyritization were also reported. The release of metals (Fe, Mg, Bi, Al, V, Cu, Cd, Ni, Pb, and Mn) above the regulatory levels during leaching was evidenced. Depyritization was found to be 79.8, 82.9, 84.7, and 89.7% for Ledo and 70.49, 73.77, 75.41, and 77.05% for Baragolai coal at 15, 25, 35, and 45 {sup o}C, respectively. A pseudo-first-order kinetic relationship with activation energies (E) of 8.1477 and 5.2378 kJ mol{sup -1} with frequency factors (A) of 8.8405 x 10{sup -4} and 2.6494 x 10{sup -4} dm{sup 3} mol{sup -1} s{sup -1} was attributed to aqueous oxidation of pyrites in Ledo and Baragolai coals, respectively. The X-ray diffraction analysis and Fourier transform infrared spectroscopy patterns indicate the presence of illite, {alpha}-quartz, hematite, chlorite, rutile, calcite, and albite as mineral phases. This investigation justifies the formation of acid mine drainage by weathering of pyrites from coal during the mining of high sulfur Makum coal fields, in Assam, India, and demonstrates one of the possible routes for its formation. 39 refs., 3 figs. 9 tabs.

  14. Microwave propagation characteristics a study over Assam valley with respect to hydrometeors

    Thimothy, K. Isaiah

    The basic aim of the research work is to study the microwave propagation characteristics with respect to hydrometeors (specially rain) and to analyse system responses towards microwave attenuation. This aim is built on the fact that the radiowaves above 10GHz suffer attenuation due to absorption and scattering by raindrops. This study has been carried out at Guwahati (260 12''N, 920E), over a line-of-sight (LOS), short haul (3.2 kms) microwave link operating at 11 GHz by P&T department. A standard observational procedure is adopted to impliment the aim. Microwave field strength measurements are taken during the period 1991-93, by tapping the AGC output of the receiver. In order to associate the attenuation with rainfall rate and raindrop size distribution, the data on rainfall and raindrop size and shape are collected simulteneously by the instruments developed for the purpose. The observational study on rainfall, raindrop size, shape and microwave attenuation is presented. Correlation between rainfall rate and microwave attenuation is computed. The observed results are then studied under the light of standard existing models like CCIR, Negative exponential, Lognormal and Global model. The observed results are also compared with those reported from various stations. Modelling on thunderstorm rain attenuation is made with an aid of dipole polarisation in raindrops of different shapes. Based on the observed results on rainfall, the rainfall rate distribution over Assam is modelled in which the rain climatic zones of Assam are classified. The thesis is organized into six chapters: CHAPTER 1: GENERAL INTRODUCTION CHAPTER 2: THEORIES AND NUMERICAL MODELS ON RAIN ATTENUATION : A REVIEW CHAPTER 3: EXPERIMENTAL TECHNIQUES CHAPTER 4: OBSERVATIONS AND ANALYSES CHAPTER 5: COMPARISON OF OBSERVED RESULTS WITH STANDARD MODELS AND MODELLING OF RAIN ATTENUATION AND RAINFALL RATE CHAPTER 6: RESULTS, DISCUSSIONS AND CONCLUSIONS CHAPTER 1 gives a brief introduction to the present

    Background & objectives: Dengue is an arboviral disease of public health importance in many parts of India and recently many cases have been reported from northeastern India. Aedes mosquitoes, which are the vectors of dengue, are widely prevalent in the region. A study was initiated in Sonitpur district of Assam to understand the spatiotemporal distribution and seasonal prevalence of dengue vectors and to identify the high risk zones. Methods: Ovitrap surveys were conducted in three randomly selected villages under each of the eight public health centres (PHC) in district Sonitpur of Assam, northeastern India during March 2011 - February 2012. Three risk zones (high, medium and low) were identified on the basis of per trap density of Aedes mosquitoes. Meteorological data were collected to study the temporal distribution of dengue vectors. Results: Aedes albopictus (99.3%) was the predominant dengue vector followed by Ae. aegypti (0.7%) recorded in the ovitraps. The highest vector density was observed during the post-monsoon (60.1 ± 18 per trap) while the lowest during the winter (7.6 ± 4.9 per trap) and the season-wise differences in the vector density were significant (P=0.005). Maximum temperature (correlation coefficient, r = 0.45) and minimum temperature (r = 0.408) showed the highest positive correlation with the vector density, whereas the number of rainy days showed high positive correlation (r = 0.185) than the total rainfall (r = 0.117). The high risk zone (Dekhiajuli, Behali, Bihaguri and Gohpur PHC) as indicated by the high larval densities of dengue vectors, 45.3 ± 18, 42.1 ± 22.3, 36.9 ± 29.1, 35.3 ± 22.6 per trap, respectively, was validated by dengue epidemiological data collected during 2012. Interpretation & conclusions: Yearlong monitoring of dengue vectors was done for the first time in this region. Monthly maximum temperature and the number of rainy days could be used for the prediction of larval density of Aedes mosquitoes. The

    Insect growth regulators (IGRs) namely, Isopropyl (E-E)-(RS)-11-methoxy-3,7,11-trimethyldodeca-2, 4-dinoate (Methoprene) and 1-(4-cyclophenyl)-3-(2,6-diflerobenzoyl) urea (Diflubenzuron) were evaluated against mosquito larvae in laboratory as well as in different breeding habitats in Tezpur, Assam. LC90 values of diflubenzuron against Culex quinquefasciatus and Aedes albopictus were 0.0022 and 0.0027 ppm respectively, while it was 0.0027 and 0.0022 ppm respectively in case of methoprene. However, LC50 values of both the IGRs were almost same in case of Ae. albopictus and Cx. quinquefasciatus (varies between 0.0009 and 0.0011 ppm). In case of methoprene, maximum mortality was observed in pupal stage though the exposure was given in all the cases to the III instar larvae. Field trials were conducted in cemented drains, small ponds and ditches. At 0.2 ppm (0.020 kg/ha) both diflubenzuron and methoprene were found to eliminate 92-96 per cent Culex and Anopheles larvae. Methoprene and diflubenzuron were found equally effective for control of mosquito breeding in different breeding habitats and provide better efficacy than conventional larvicides and biocides.

    A study was made on the physico-chemical properties of water and phyto and zooplankton communities of Baskandi anua, an oxbow lake of South Assam during March to August, 2009. Analyses of water showed acidic to slightly alkaline pH (5.4-7.9) with dissolved oxygen ranging from 4.26 to 11.83 mgl(-1) and total alkalinity from 31.25 to 65 mg l(-1), indicating the productive nature of water. Free CO2 fluctuated from 2.93 to 15.04 mgl(-1). PO4 and NO3 concentration ranged from 0.15 to 1.4 mg l(-1) and 0.06 mg l(-1) to 4.94 mg l(-1), respectively. Conductivity, pH and free CO2 were found higher at the sites surrounded by paddy fields. Mean values of physico-chemical parameters significantly varied between the sites and were found to be influenced by one or more of the following factors viz. rainfall, depth and influx from adjacent paddy field. A total of 30 phytoplankton taxa and 12 zooplankton taxa with qualitative dominance of Chlorophyceae were recorded. The study revealed that water quality of the lake was good for aquaculture. Hence, the lake should be protected and best management practices should be implemented for sustainable production.

    This study was undertaken to assess the heavy metal concentration of the drinking water with respect to zinc, copper, cadmium, manganese, lead and arsenic in Kamrup district of Assam, India. Ground water samples were collected from tube wells, deep tube wells and ring wells covering all the major hydrogeological environs. Heavy metals in groundwater are estimated by using Atomic Absorption Spectrometer, Perkin Elmer Analyst 200. Data were assessed statistically to find the distribution pattern and other related information for each metal. The study revealed that a good number of the drinking water sources were contaminated with cadmium, manganese and lead. Arsenic concentrations although did not exceeded WHO limits but was found to be slightly elevated. Copper and zinc concentrations were found to be within the prescribed WHO limits. An attempt has also been made to ascertain the possible source of origin of the metals. Positive and significant correlation existing between manganese with zinc and copper indicates towards their similar source of origin and mobility. In view of the present study and the level of heavy metal contamination, it could be suggested to test the potability of the water sources before using it for drinking purpose.

    An inventory of tree diversity in traditional homegardens of Meitei community was conducted in a Bontarapur village in Cachar district of Barak Valley, Assam. Meitei homegarden locally called Ingkhol exhibits a wide diversity in size, shape, location and composition. Seventy one tree species were enumerated from 50 homegardens belonging to 60 genus and 35 families. Among the families encountered, Rutaceae was the dominant family (4 genus and 7 species) followed by Meliaceae (5 genus and 5 species), Arecaceae (4 genus and 4 species) and Moraceae (3 genus and 5 species). Total 7946 tree individuals were recorded, with the density of 831 No ha(-1) of and total basal area of 9.54 m2 ha(-1). Areco catechu was the dominant species with the maximum number of individuals. Other dominant trees include Mangifera indica, Artocarpus heterophyllus, Citrus grandis, Parkia timoriana, Syzygium cumini and Psidium guajava. Being a cash crop, the intensification of betel nut has been preferred in many homegardens. Homegardens form an important component of land use of Meitei community which fulfills the socio-cultural and economic needs of the family and helps in conserving plant diversity through utilization.

    Hemoglobin E (HbE) is estimated to affect at least one million people around the world. Carrier frequency of hemoglobin E/β-thalassemia (HbE/β-thalassemia) is highest in Southeast Asia, reaching as high as 60% in parts of Thailand, Laos, and Cambodia. In the Indian subcontinent, highest frequency is observed in The Northeast regions, but relatively rare in rest of the country. Increasing migration of population from highly affected areas is resulting in rising prevalence in The South and other parts of India. HbE/β-thalassemia is characterized by marked clinical diversity, phenotypic instability, and age-related changes in adaptation to anemia. This paper reports a case of HbE disease in an adult immigrant from Assam and documents the difficulties encountered in the definitive subtyping of HbE hemoglobinopathy. Distinguishing between homozygous HbE disease and HbE/β-thalassemia is a challenge to hematopathologist as both are clinically and hematologically similar. PMID:27365922

    Tea industry is a labor intensive agro-industry and filariasis is mostly localized among the tea garden workers in Assam. The workers live inside the gardens in colonies. Studies conducted in two cosecutive years revealed that among the host seeking Culex quinquefasciatus average infection rate was 4.6% and with 2.1 larvae per mosquito. The overall prevalence of infective mosquitos was 0.8% with average L3 load of 2.0 per mosquito. The probability of infected mosquitos surviving to have complete development of filarial larvae (13 days) was 0.17. The expectation of infective life was 1.416 days for man biting Cx. quinquefasciatus and the estimated adult survival rate of was 87.6%. It has been estimated that a total of 22,569 mosquito bites were received/man/year in tea garden environment out of which 182 bites/man/year were infective (0.806%). The monthly biting rate varied from 310-4,758.5 bites per man (mean 1,846 +/- 1,389.7 SD). Monthly transmission index of W. bancrofti filaria showed two periods of transmission. In both the year no infection was detected during February and March and infection rate remained low up to May (average infection in April 0.72% and in May 0.48%).

    Introduction Co-infection of Japanese Encephalitis (JE) and Cysticercosis is attributed mainly to the common epidemiological features between the two diseases. Not much is known about the clinical implications of one infection over the other. Aim The study aimed at establishing whether JE-Cysticercosis co-infection is prevalent in the Upper Assam districts and to explore additional details about such co-infections both clinically and epidemiologically. Materials and Methods The present study was a retrospective cross-sectional hospital based study conducted between July 2013 and June 2014 and included 272 Acute Encephalitis Syndrome (AES) patients. Out of this, 137 JE positive and 135 non-JE Acute encephalitis patients were taken as cases and controls respectively. The diagnosis of JE and Cysticercosis was established by ELISA. Statistical Analysis EpiInfo ver. 7 was used for statistical analysis. Chi-square was used and p-value < 0.05 was considered to be statistically significant. Results The association of Cysticercosis with JE was found to be statistically significant (14.6%, p = 0.0019) in the cases with reference to the controls (3.7%). Moreover, the co-infections were found to be more common in case of adults (19.32%, p = 0.0360); with males having a greater odds (5.25, p = 0.0008) of harbouring the parasite as compared to females. Conclusion The study proves that the association of Cysticercosis and JE holds true in this region. PMID:27437215

    Salmonella enterica serovar Weltevreden has been a rare cause of acute gastroenteritis occurring worldwide. Here, we report an outbreak of food poisoning in a tea garden. To determine the aetiological agent and risk factors responsible for the outbreak and to take necessary steps for prevention of future outbreaks. Affected area was visited by a team of microbiologists for collecting stool samples/rectal swabs from affected patients. Samples were processed by culture followed by confirmation of the isolates biochemically, automated bacterial identification system, conventional serotyping and molecular typing. Water samples were also processed for detection of faecal contamination. Antimicrobial susceptibility testing was performed by Kirby-Bauer disc diffusion technique according to the Clinical Laboratory Standard Institute guidelines. The isolates were confirmed as S. enterica subspecies enterica serovar Weltevreden. They were found sensitive to ampicillin, amoxycillin-clavulanic acid, ciprofloxacin, ofloxacin, norfloxacin, cefotaxime, ceftriaxone, co-trimoxazole and doxycycline. Water samples showed high-level faecal contamination. Source of outbreak was found to be drinking water contaminated with dead livestock. House to house visit was made for early diagnosis and treatment of the cases, awareness campaigning and chlorination of drinking water. This report emphasises the geographical distribution of this organism in Assam. As S. Weltevreden is widely distributed in domestic animals, people should be made aware of immediate reporting of any unusual death among the livestock and their safe disposal which can significantly reduce the incidence of non-typhoidal salmonellosis in the country.

    Malaria is endemic and a major public health problem in north east (NE) region of India and contributes about 8-12 % of India's malaria positives cases. Historical morbidity pattern of malaria in terms of API (Annual Parasite Incidence) in the state of Assam has been used for delineating the malaria incidence hotspots at health sub centre (HSC) level. Strong spatial autocorrelation (p < 0.01) among the HSCs have been observed in terms of API (Annual Parasite Incidence). Malaria incidence hot spots in the state could be identified based on General G statistics and tested for statistical significance. Spatial correlation of malaria incidence hotspots with physiographic and climatic parameters across 6 agro-climatic zones of the state reveals the types of land cover pattern and the range of elevation contributing to the malaria outbreaks. Analysis shows that villages under malaria hotspots are having more agricultural land, evergreen/semi-evergreen forests with abundant waterbodies. Statistical and spatial analyses of malaria incidence showed a significant positive correlation with malaria incidence hotspots and the elevation (p < 0.05) with villages under malaria hotspots are having average elevation ranging between 17 to 240 MSL. This conforms to the characteristics of two dominant mosquito species in the state Anopheles minimus and An. baimai that prefers the habitat of slow flowing streams in the foot hills and in forest ecosystems respectively.

    The spatial distribution of arsenic (As) concentrations along three classified hydrogeomorphological zones in the Brahmaputra River Valley in Assam (India) have been investigated: zone I, comprising the piedmont and alluvial fans; zone II, comprising the runoff areas; and zone III, comprising the discharge zones. Groundwater (150 samples) from shallow hand-pumped and public water supply wells (2-60 m in depth) was analysed for chemical composition to examine the geochemical processes controlling As mobilization. As concentrations up to 0.134 mg/L were recorded, with concentrations below the World Health Organization and the Bureau of Indian Standards drinking-water limits of 0.01 mg/L being found mainly in the proximal recharge areas. Eh and other redox indicators (i.e., dissolved oxygen, Fe, Mn and As) indicate that, except for samples taken in the recharge zone, groundwater is reducing and exhibits a systematic decrease in redox conditions along the runoff and discharge zones. Hydrogeochemical evaluation indicated that zone I, located along the proximal recharge areas, is characterized by low As concentration, while zones II and III are areas with high and moderate concentrations, respectively. Systematic changes in As concentrations along the three zones support the view that areas of active recharge with high hydraulic gradient are potential areas hosting low-As aquifers.

    Trends in rainfall, rainy days and 24 h maximum rainfall are investigated using the Mann-Kendall non-parametric test at twenty-four sites of subtropical Assam located in the northeastern region of India. The trends are statistically confirmed by both the parametric and non-parametric methods and the magnitudes of significant trends are obtained through the linear regression test. In Assam, the average monsoon rainfall (rainy days) during the monsoon months of June to September is about 1606 mm (70), which accounts for about 70% (64%) of the annual rainfall (rainy days). On monthly time scales, sixteen and seventeen sites (twenty-one sites each) witnessed decreasing trends in the total rainfall (rainy days), out of which one and three trends (seven trends each) were found to be statistically significant in June and July, respectively. On the other hand, seventeen sites witnessed increasing trends in rainfall in the month of September, but none were statistically significant. In December (February), eighteen (twenty-two) sites witnessed decreasing (increasing) trends in total rainfall, out of which five (three) trends were statistically significant. For the rainy days during the months of November to January, twenty-two or more sites witnessed decreasing trends in Assam, but for nine (November), twelve (January) and eighteen (December) sites, these trends were statistically significant. These observed changes in rainfall, although most time series are not convincing as they show predominantly no significance, along with the well-reported climatic warming in monsoon and post-monsoon seasons may have implications for human health and water resources management over bio-diversity rich Northeast India.

    Severe flooding of the Brahmaputra River during the monsoon season and continuous rainfall in the northeast region (NER) of India cause an enormous loss of ginger crop every year. In this context, the present study investigates the variation in the essential oil composition and oleoresin and [6]-gingerol contents in 10 different fresh ginger cultivars harvested at 6- and 9-month maturity from five different states of NER. Monoterpenes, sesquiterpenes, and citral composition in the essential oil were evaluated to ascertain their dependence upon the maturity of ginger. Except Mizoram Thinglaidum, Mizoram Thingria, Nagaland Nadia, and Tripura I ginger cultivars, all other cultivars showed an increase in the citral content during the maturity that was observed for the first time. At 6-month maturity, a higher undecanone level was found in Nagaland Nadia (7.36 ± 0.61%), Tripura I (6.23 ± 0.61%), and Tripura III (9.17 ± 0.76%) cultivars, and these data can be used as a benchmark to identify those immature varieties. Interestingly, the Nagaland Nadia cultivar showed higher ar-curcumene (9.57 ± 0.58%) content than zingiberene (5.84 ± 0.24%), which was unique among all cultivars. Ginger harvested at 9-month maturity from the Tripura II cultivar had the highest citral content (22.03 ± 0.49%), and the Meghalaya Mahima cultivar had the highest zingiberene content (29.89 ± 2.92%). The oleoresin content was found to decrease with maturity in all cultivars, except Assam Fibreless and Manipur I. Moreover, the highest oleoresin (11.43 ± 0.58 and 9.42 ± 0.63%) and [6]-gingerol (1.67 ± 0.03 and 1.67 ± 0.05 g) contents were observed for Tripura II and Nagaland Nadia, respectively. This study suggests that Tripura and Nagaland are the most ideal locations in NER for ginger cultivation to obtain high yields of oleoresin and [6]-gingerol contents and harvesting at the 6-month maturation will compensate for the loss of ginger crop caused by the Brahmaputra River flooding in NER

    Background The present study addresses the use of zootherapy in the traditional healthcare system of the Biate tribe of Dima Hasao district, Assam, India. It sought to identify the different species used for zootherapeutic use with the detailed methods of usages to create awareness and contribute to the conservation and sustainable utilization of the resources. Method 15 Biate villages within the district of Dima Hasao were surveyed through semi-structured questionnaires and informal interviews. Detailed information on the uses of each animal was recorded. Species were identified using standard literature. Fidelity level (FL) was calculated to demonstrate the percentage of respondents claiming the use of a certain animal for the same major purposes. Result The study documents 34 species for the treatment of about 34 different ailments. The largest number of species reported was mammals with17 species. Maximum number of species has been reported for the treatment of diabetes and its high fidelity levels warrants in-depth studies to establish its pharmacological activity. The usages documented herein are unique to the Biate tribe. Very often, these animals are hunted and sold openly at the local markets in the lure of quick money. A 300 gm live Gekko gecko may fetch a sum of 2,50,000 Indian Rupees (INR), and smoked meat of Hoolock hoolock cost approximately 250–300 INR per kg. Animals are also hunted for its hide. The unrestricted hunting of species like Capricornis sumatraensis has almost wiped out the population within the district. Some species are also reared as pets while some are used for display as a sign of expertise in hunting. The present study has documented the usage of at least 15 animals listed in the IUCN Red List. Conclusion The study illustrates the in-depth knowledge of the Biate tribe on zootherapy. Systematic investigation to identify the active ingredient may lead to the development of new drugs, which would prompt protection of these valuable

    Background & objectives: Typhoid fever is a global health problem and is also endemic in India. An outbreak of fever occurred in January 2014 in Jorhat Town in Assam, India. Here we report the results of an investigation done to find out the aetiology and source of the outbreak. Methods: The affected areas were visited on January 23, 2014 by a team of Jorhat district Integrated Disease Surveillance Project personnel. A total of 13 blood samples from patients with fever as first symptom and six water samples were collected from the affected areas. The blood samples were cultured and isolates were identified using standard biochemical tests. Isolates were also tested for antimicrobial sensitivity. Widal test was performed on 10 of the 13 blood samples collected. Sanitary survey was carried out to find any leakage in the water supply and also the sewage system of the Jorhat town. Results: Blood culture yielded Salmonella enterica serovar Typhi in six (46.15%) patients whereas Widal test was positive in 10 (76.9%) of 13 patients. Water culture showed presumptive coliform count of >180/100 ml in two out of the six samples tested. Salmonella Typhi was also isolated from water culture of these two samples. Sanitary survey carried out in the affected places showed that the water supply pipes of urban water supply were in close proximity to the sewage drainage system and there were few leakages. Interpretation & conclusions: The outbreak occurred due to S. Typhi contaminating the water supply. Sanitation and immunization are the two most important components to be stressed to prevent such outbreaks. PMID:28256469

    Water, most precious natural resource on earth, is vital to sustain the natural system and human civilisation on the earth. The Assam state located in north-eastern part of India has a relatively good source of ground water due to their geographic and physiographic location but there is problem deterioration of groundwater quality causing major health problem in the area. In this study, I tried a integrated study of remote sensing and GIS and chemical analysis of groundwater samples to throw a light over groundwater regime and provides information for decision makers to make sustainable water resource management. The geospatial modelling performed by integrating hydrogeomorphic features. Geomorphology, lineament, Drainage, Landuse/landcover layer were generated through visual interpretation on satellite image (LISS III) based on tone, texture, shape, size, and arrangement of the features. Slope layer was prepared by using SRTM DEM data set .The LULC of the area were categories in to 6 classes of Agricultural field, Forest area ,River, Settlement , Tree-clad area and Wetlands. The geospatial modelling performed through weightage and rank method in GIS, depending on the influence of the features on ground water regime. To Assess the ground water quality of the area 45 groundwater samples have been collected from the field and chemical analysis performed through the standard method in the laboratory. The overall assessment of the ground water quality of the area analyse through Water Quality Index and found that about 70% samples are not potable for drinking purposes due to higher concentration Arsenic, Fluoride and Iron. It appears that, source of all these pollutants geologically and geomorphologically derived. Interpolated layer of Water Quality Index and geospatial modelled Groundwater potential layer provides a holistic view of groundwater scenario and provide direction for better planning and groundwater resource management. Study will be discussed in details

    The Samchampi-Samteran alkaline igneous complex (SAC) is a near circular, plug-like body approximately 12 km2 area and is emplaced into the Precambrian gneissic terrain of the Karbi Anglong district of Assam. The host rocks, which are exposed in immediate vicinity of the intrusion, comprise granite gneiss, migmatite, granodiorite, amphibolite, pegmatite and quartz veins. The SAC is composed of a wide variety of lithologies identified as syenitic fenite, magnetite ± perovskite ± apatite rock, alkali pyroxenite, ijolite-melteigite, carbonatite, nepheline syenite with leucocratic and mesocratic variants, phonolite, volcanic tuff, phosphatic rock and chert breccia. The magnetite ± perovskite ± apatite rock was generated as a cumulus phase owing to the partitioning of Ti, Fe at a shallow level magma chamber (not evolved DI = O1). The highly alkaline hydrous fluid activity indicated by the presence of strongly alkalic minerals in carbonatites and associated alkaline rocks suggests that the composition of original melt was more alkalic than those now found and represent a silica undersaturated ultramafic rock of carbonated olivine-poor nephelinite which splits with falling temperature into two immiscible fractions—one ultimately crystallises as alkali pyroxenite/ijolite and the other as carbonatite. The spatial distribution of varied lithotypes of SAC and their genetic relationships suggests that the silicate and carbonate melts, produced through liquid immiscibility, during ascent generated into an array of lithotypes and also reaction with the country rocks by alkali emanations produced fenitic aureoles (nephelinisation process). Isotopic studies (δ18O and δ13C) on carbonatites of Samchampi have indicated that the δ13C of the source magma is related to contamination from recycled carbon.

    Present investigation was carried out in Cachar district of Assam over a period of two years (May 2007-April 2009) to understand the seasonal ecology of Isotomina thermophila (Axelson, 1900) in secondary succession and homegarden ecosystems. Population was found to be maximum during July 2008 (7949.05 No. m(-2)) and September 2008 (7949.05 No. m(-2)) in homegarden whereas the peak was recorded in secondary succession during September 2008 (13656.05 No. m(-2)). Least population was encountered during March 2008 (1222.93 No. m(-2)) and April 2008 (1630.57 No. m(-2)) in homegarden and secondary succession, respectively. It may be due to the fact that, vital activity of this species effected in the dry period or migrate towards lower soil profile in search of food and moisture. Linear regression analysis established the hypothesis that all the environmental variables showed positive and significant influence on the population dynamics whereas in homegarden, rainfall (r = 0.36, p > 0.05) did not show any influence. In multiple regression analysis positive and significant influences (p < 0.05) were recorded for both the investigated sites. Rainfall, relative humidity and temperature facilitated the soil moisture, microbial activity, litter decomposition may favour the reproduction and growth rate of the species. Among microclimatic conditions except soil pH all other parameters exhibited significant correlations (p < 0.05) with population. Based on the present investigation, it can be concluded that I. thermophilia does not differ much with the general ecology of collembolans in this sub humid climate.

    Assam is very rich in plant biodiversity as well as in ethnic diversity and has a great traditional knowledge base in plant resources. It is inhabited by the largest number of tribes and they lead an intricate life totally dependent on forest plants. The Mising is the major section and second largest tribal community of Assam and have a rich tradition of religion and culture. Their religious practices and beliefs are based on supernaturalism. A study of the plants related to magico religious beliefs in Dobur Uie of Mising is carried out. The results revealed the use of 30 plants belonging to 23 families. All plant species are used both in religious purpose as well as in the treatment of different ailments. Details of the uses of plants and conservational practices employed in Dobur Uie are provided. Our findings on the use of plants in Dobur Uie ritual reflect that some plants are facing problems for survival and they need urgent conservation before their elimination. Because this elimination may threat the rich tradition of Mising culture. Most of the plants that are domesticated for different rituals are almost same in all Mising populated areas.

  6. Evaluation of media used in indigenous household iron filter units of rural and semi-urban Assam, India.

    2007-10-01

    Ground water, the major source of drinking water in rural and semi-urban areas of Assam, contains an excessive amount of iron varying from 1 to 10 mg/L or more. People in Assam invariably use household iron filter units-indigenously developed using locally available wooden charcoal and river sand as filter media. The present work is aimed to evaluate effectiveness of wooden charcoal and river sand for its iron adsorption capacity. The experiments were carried at a fixed pH of 5.5 with zero dissolved oxygen levels. Batch kinetic studies indicated rapid uptake of Fe(II) by wooden charcoal in the first 20 min. while the uptake with sand was relatively slower. The adsorption seemed to govern by diffusion within pores of adsorbents and Fe(II) removal mechanism appeared to be complex. Equilibrium studies indicated favorable adsorption of Fe(II) on both adsorbents and followed Langmuir isotherm. Column studies indicated relatively quicker breakthrough through sand bed as compared to charcoal bed. Overall, wooden charcoal and sand both seemed to have potentials for Fe(II) removal.

    Subcutaneous mycoses are a group of fungal infections of dermis and subcutaneous tissue which consist of sporotrichosis, chromoblastomycosis, phaeohyphomycosis, hyalohyphomycosis, mycetoma, subcutaneous zygomycosis, rhinosporidiosis, lobomycosis and disseminated penicilliosis. A total of 46 consecutive patients with clinically suspected subcutaneous mycoses attending various departments of Assam Medical College and Hospital were included in this prospective study to know the prevalence of subcutaneous mycoses in this eastern part of Assam. Direct microscopy in 10 and 40 % KOH, histopathological examination of biopsied tissue, colony characteristics on Sabourauds dextrose agar media both at 25 and 37 °C and detailed morphology of each fungus on lactophenol cotton blue mount were the basis of identification of the fungi. Subcutaneous mycoses were confirmed in 32.6 % (n = 15) cases. Out of 15 positive cases of subcutaneous mycoses, chromoblastomycosis was detected in six cases (n = 40 %), hyalohyphomycosis in three cases (n = 20 %), and lymphocutaneous sporotrichosis, disseminated penicilliosis and mycetoma in two cases each (n = 13.3 % each). In this study, seven different species of fungus were found to be responsible for five different clinical types of subcutaneous mycosis. Cladosporium cladosporioides, Bipolaris spicifera and Curvularia lunata were responsible for chromoblastomycosis, Fusarium oxysporum and Aspergillus terreus for hyalohyphomycosis, C. lunata for mycetoma, Sporothrix schenckii for lymphocutaneous sporotrichosis and Penicillium marneffei for disseminated penicilliosis. C. cladosporioides and C. lunata were the commonest black fungi causing subcutaneous mycosis in this sub-Himalayan belt. Rare species C. cladosporioides, B. spicifera and C. lunata were found to be causing chromoblastomycosis in this study.

    The colon and rectum are the parts of digestive system of human beings. Cancer affecting either of these organs may be called colorectal cancers. Conventional cancer chemotherapy is not very effective for treatment of colorectal cancer, as the drug molecule does not reach the target site at therapeutic concentration, on the other side they produces sever systemic toxic effect. Aim of this study was to develop a novel colon targeted Assam Bora rice starch compression coated tablet for site specific delivery of 5-FU to the colon without the drug being released in stomach or small intestine. Core tablet of 5-FU was prepared using microcrystalline cellulose (MCC) and spray dried lactose by direct compression method. The in vitro drug release study in different physiological environment confirmed insignificant release of 5-FU in physiological condition of stomach and small intestine further fast and major drug release in caecal content. In vivo drug absorption of optimized formulation was performed in order to establish its targeting potential in colon. It is concluded from the present study that Assam Bora rice starch can be used as a drug carrier for an effective colon targeted delivery system for drugs effective against the large intestine resident disease condition.

    1999-01-01

    Two hundred eighty-two soybean cultivars from the variety testing programs of Arkansas and Mississippi were tested in greenhouse pot experiments during summer 1998 to identify soybean cultivars with resistance to the reniform nematode, Rotylenchulus reniformis. Also included in the tests were the resistant cultivars Forrest and Hartwig, the susceptible control Braxton, and fallow infested soil, which were used as controls. Numbers of reniform nematode extracted from the soil and roots and the ratio of the numbers reproducing on each cultivar compared to the number reproducing on Forrest are reported. Cultivars with reproduction not significantly different from Forrest were classified resistant, whereas those with greater reproductive indices were considered susceptible. One of the 18 cultivars of relative maturity group (RMG) ≤4.4 was classified as resistant. For the 86 cultivars of RMG 4.5-4.9, 18 were found to be resistant. Of the 43 cultivars of RMG 5.0-5.4, 16 were resistant, while 43 of the 91 cultivars of RMG 5.5-5.9 were resistant. Fifteen of the cultivars with an RMG of ≥6.0 were classed as resistant. These data will be useful in the selection of soybean cultivars to use in rotation with cotton to help control the reniform nematode. PMID:19270934

    2014-11-01

    Several outbreaks of Salmonella enterica infections have been linked to tomatoes. One cost-effective way to complement on-farm preventive Good Agricultural Practices is to identify cultivars with inherent decreased susceptibility to Salmonella colonization. Fruit and leaves of 13 tomato cultivars with distinct phenotypes were screened to evaluate their susceptibility to Salmonella epiphytic colonization. Field-grown fruit or gnotobiotically grown seedling leaves were spot inoculated in replicate with either Salmonella Typhimurium LT2 or a tomato outbreak-associated strain of Salmonella Newport. Initial loads of the Salmonella inocula were 2.5 log CFU per fruit and 3.5 or 7.0 log CFU per seedling. Salmonella cells were retrieved and enumerated using direct plating after 24 h of incubation at room temperature for fruit and 72 h at 26°C during the day and 18°C at night for seedling leaves. Epiphytic colonization of fruit by S. enterica was cultivar-dependent and serotype-specific, but did not necessarily correlate with leaf colonization. Fruit of cultivar Heinz-1706 were the least colonized by Salmonella Newport, while the highest populations were retrieved from fruit of Nyagous. By contrast, seedling leaves supporting the lowest populations were Florida 91 VF and the highest were Virginia Sweets for Salmonella Newport. For Salmonella Typhimurium the lowest was Nyagous and the highest was Heinz-1706 and Moneymaker. The tomato outbreak strain of Salmonella Newport attained higher population densities on fruit than did Salmonella Typhimurium, suggesting better adaptation to tomato fruit colonization. Salmonella Newport populations were significantly lower on leaves, but not fruit of the near-isogenic line Movione, compared with the parent cultivar Moneymaker, suggesting the immunity conferring gene Pto could be responding to this outbreak strain. Susceptibility of tomato fruit to Salmonella colonization is highly variable and could be one criterion for cultivar

Found only in Florida and Georgia, this species is related to the common snapping turtle. It is considered a dangerous turtle because it can snap very quickly with its extremely strong jaws. Its tail, which is almost as long as its shell, has saw-edges along the top. The shell also has rough points down the middle. The shell is tan to dark brown and may have green algae growing on it. It can grow to 17 inches long and weigh 45 pounds. Snapping turtles usually live in ponds under the shadows and don’t like to rest in the sun like most turtles. They eat almost anything: water bugs, fish, lizards, small birds, mice, plants and even dead animals

    2007-10-01

    A hydrobiological study conducted in nine different ponds of a rural area of Barak Valley, Assam, showed that the concentrations of chemical parameters like dissolved oxygen, free carbon dioxide, pH, conductivity alkalinity nitrate, phosphate, calcium, magnesium, copper and zinc are within the permissible levels of drinking water quality standard of WHO and ISI. However iron content was higher in most of the ponds. A clear indirect relationship between iron concentration and euglenoids has been observed. Major phytoplankton taxa present in the ponds are Chlorophyceae, Cyanophyceae, Bacillariophyceae and Euglenophyceae. The study reveals that rural ponds can be a very good source of water for drinking, domestic use and fishery and should be conserved at any cost.

    1999-12-01

    Temporal changes in the biting density and host-seeking periodicity of Culex quinquefasciatus, the vector of bancroftian filariasis, were studied for two years in the tea agro-ecosystem of Assam, India. Average biting density of the vector varied from 0.8/hour in December to 13.3/hour in March. Minimum temperature was found to have a limiting effect on the biting density of the vector mosquitos. Multiple regression analysis showed that the rainfall and minimum temperature were significant factors influencing biting density of this vector mosquito. The biting rhythm of Cx. quinquefasciatus was found to be nocturnal with two distinct peak periods of biting activity. The first peak was around 19.00 to 20.00 hours and the second peak period was around 22.00 to 23.00 hours. Biting activity however was seen throughout the night with declining trend as the night proceeded.

    One of the key goals of the Florida Center is to obtain a maximum of useful information on propagation behavior unique to its subtropical weather and subtropical climate. Such weather data is of particular interest when it is (or has the potential to become) useful for developing and implementing techniques to compensate for adverse weather effects. Also discussed are data observations, current challenges, CDF's, sun movement, and diversity experiments.

    On the basis of a mineral survey the Savannah Roadless Area in Florida was appraised to offer little promise for the occurrence of mineral resources. The commodities identified in the area are deposits of sand and gravel; however, they are deeply buried, far from potential markets, and more readily accessible material exists outside the roadless area. The possibility that oil and gas might occur in the Jurassic Smackover Formation or in other formations at depth cannot be ruled out.

    Much of central Florida, including this detailed view of Orlando (28.5N, 81.0W) can be seen in this single photo. Disney World is at the top center of the scene and the crescent shaped Lake Tohopekaliga is near the bottom. The large round lakes are believed to be sinkholes formed during glacial times when ocean levels were several hundred feet lower than the present. Linear patterns east of Orlando are thought to be ancient shoreline ridges.

  9. Use of multiline cultivars and cultivar mixtures for disease management.

    PubMed

    Mundt, C C

    2002-01-01

    The usefulness of mixtures (multiline cultivars and cultivar mixtures) for disease management has been well demonstrated for rusts and powdery mildews of small grain crops. Such mixtures are more useful under some epidemiological conditions than under others, and experimental methodology, especially problems of scale, may be crucial in evaluating the potential efficacy of mixtures on disease. There are now examples of mixtures providing both low and high degrees of disease control for a wide range of pathosystems, including crops with large plants, and pathogens that demonstrate low host specificity, or are splash dispersed, soilborne, or insect vectored. Though most analyses of pathogen evolution in mixtures consider static costs of virulence to be the main mechanism countering selection for pathogen complexity, many other potential mechanisms need to be investigated. Agronomic and marketing considerations must be carefully evaluated when implementing mixture approaches to crop management. Practical difficulties associated with mixtures have often been overestimated, however, and mixtures will likely play an increasingly important role as we develop more sustainable agricultural systems.

  10. Surface Break and Coseismic Slip of the Great 1950 Assam Earthquake and Previous Events along the Eastern Himalayan Syntaxis

    The Eastern Himalayan Syntaxis (EHS) is a complex tectonic region where the nearly orthogonal Himalayan and Burmese ranges meet. The Indian plate (or Assam block) subducts beneath the Tibetan plateau while sliding northwards relative to northwest Myanmar and Yunnan. Present-day deformation in this 200 x 200 km2 wide zone is mostly accommodated by two nearly orthogonal thrust systems: the North dipping, N60E striking Himalayan Main Frontal Thrust (MFT) and the NE dipping, N130E striking Mishmi Thrust (MST). We have shown that the great M8.6, 1950 Assam earthquake, which triggered huge landslides and numerous aftershocks along both thrusts, ruptured the surface from at least Wakro to Pasighat, a minimum distance of ≈ 200 km. Here, we map more carefully and characterize quantitatively the surface rupture of that event. We analyze the heights, shapes, and slopes of topographic profiles leveled using Total Station and kinematic GPS across steep scarps, and atop uplifted Quaternary alluvial terraces, to document 1950 co-seismic and older cumulative surface uplifts. Co-seismic vertical throws differ between the two thrusts (≈ 7 m and ≈ 2 m, along the MST and MFT, respectively). The stratigraphy along freshly cut terrace risers and along paleo-seismological trench walls is used to constrain the distinctly different dips of the two thrusts (≈ 14° and < 8° along the MST and MFT, respectively). Both 14C and 10Be dating results are combined to assess the ages of uplifted surfaces. The results are then used to evaluate the rates of Quaternary surface uplift and shortening across both active thrusts. At two sites, our data suggests characteristic slip on either thrust for at least the last two large events, improving our estimate of the return time (≈ 1300 ± 500 at Wakro) of recent great earthquakes along these connected thrusts of the Himalayan and Burmese ranges.

  11. Socio-Economic Appraisal of Flood Hazard among the Riparian Communities: Case Study of Brahmaputra Valley in Assam; India

    2017-04-01

    Brahmaputra valley of Assam is one of the most hazard prone areas of the Indian subcontinent. Recurring floods have severely affected the riparian communities of the region since time immemorial. But, the frequency of the problem has been intensified after the great earthquakes of 1897 and 1950. These two extreme earthquakes have disturbed the geological setting of the basin and the channel morphology has been altered henceforth. The impact of floods on riparian communities in Brahmaputra valley has been abysmal. During the monsoon season almost 30 per cent of the valley has been inundated with floods and the riparian communities are mostly affected. Large chunk of people have been uprooted from their native lands due to recurring floods in the low lying areas of the region. Although it is impossible to quantify the human tragedy during the natural disasters, but one can easily understand the situation by the facts that about 1.8 million people and 200,000 hectares of farmland were affected in the 2016 floods of Assam. In the present study, an attempt has been made to assess the spatio-temporal changes of the morphology of Brahmaputra River and its impact on the livelihood of the riparian communities. For that, LANDSAT and SENTINEL imageries have been used to examine the shifting of bank lines of three decades. CARTOSAT DEM has been used to prepare the FLOOD HAZARD ZONATION map of the Brahmaputra valley to examine the flood vulnerable areas of the region. The present study also tries to explain the livelihood condition of the Internally Displaced Persons and their social cohesion.

  12. Alcohol use among school-going adolescent boys and girls in an industrial town of Assam, India

    PubMed Central

    Mahanta, Beauty; Mohapatra, P. K.; Phukan, N.; Mahanta, J.

    2016-01-01

    Background: Some people in Northeast India prepare rice-based alcoholic drinks in the household. People use these drinks in religious and social functions, and these are taken even in the presence of parents and elders. Easy access to illicit substances in industrial towns and lack of social inhibition for intake of homemade alcohol might increase the vulnerability of youth to these habits. Objective: To estimate the prevalence of alcoholic drink user among school-going adolescent students in an industrial town of Assam. Materials and Methods: A cross-sectional survey was designed to collect the data using a predesigned questionnaire. Personal interview was conducted to collect the data about pattern of alcohol use, type of alcoholic drinks they use, duration, and information about parents and peer. Data were analyzed using Epi-info 17 and Statistical Package for Social Sciences-17.0 (Chicago, USA, SPSS Inc.). Results: About 36% out of 1285 students have tasted/used homemade alcoholic drinks (HADs) and 12.3% used commercially available alcoholic drinks (CADs). Significantly higher numbers (P < 0.001) of adolescent students (≥15 years) used CAD in comparison to children (<15 years). However, the number of younger students was higher in using HAD. Minimum age at first experience of CAD was 7 years and that of HAD was 4 years; the duration varied from 1 to 8 years and 1–15 years, respectively. Parent's behavior of taking tobacco and/or alcohol influenced the habit of their children. Father's habit was found to be associated with male offspring's habit of taking CAD. About 16% of the students used one or more substances along with alcohol. Conclusion: High percentage of adolescents in the industrial town of Assam use alcoholic drinks with a male preponderance. They taste alcoholic drinks at a very young age. Parent's indulgence in taking tobacco, alcohol, or both was found to influence higher intake by their offspring. PMID:27385848

  13. Contribution of Immunization Weeks toward improving coverage, access to services, and completion of recommended childhood vaccinations in Assam, India.

    Recommended childhood vaccines have typically been provided through routine immunization programs. Recently, implementation of strategies that use campaign-like features for providing all the recommended childhood immunizations have been utilized to increase vaccination coverage. Between January 2006 and January 2008, Assam, India, conducted Immunization Weeks (IWs), a periodic campaign-like approach for providing the recommended childhood vaccines generally administered through the routine Universal Immunization Program (UIP). Using data from a household vaccination coverage survey conducted in 5 districts of Assam in late-2007/early-2008 among children 12-28 months of age, a secondary analysis was conducted for a subset of children with vaccination cards to assess the impacts of implementing the IW-strategy. Sixty-five percent of the 3310 surveyed children received at least one vaccine dose through an IW. Without IWs, coverage would likely have been lower for all vaccines (e.g., 75% measles vaccine coverage including IWs doses and an estimated 61% without IWs). The proportion of children receiving at least one IW dose was significantly different depending on the child's residence; 72% in hard-to-reach char areas, 66% in rural areas and 53% in urban areas (p=0.01). Overall, 2085 (63%) of children were fully vaccinated; of these 60% received a combination of IW and UIP doses, 35% received doses only through the UIP, and 5% received doses only through IWs. A delay in administration later than the recommended ages was found for both UIP doses and for IW doses (e.g., for measles vaccine, UIP doses were 6.9 weeks delayed and IW doses 13.6 weeks delayed). Among this sample of vaccinated children, IWs appeared to increase vaccination coverage and improve access to services in hard-to-reach areas. However, the UIP appeared to be a better system for ensuring that children received all doses in the recommended vaccination series.

    On 8 November 1968 in Gainesville, Florida, I removed a male Bronzed Cowbird (Tangavius a. aeneus) from a blackbird decoy trap containing a large number of Brown-headed Cowbirds (Malothrus ater). Oliver L. Austin, Jr., at the Florida State Museum, verified the species identification by noting the notched inner webs of the outer three primaries, a characteristic of the genus. The subspecific identification was made at the U. S. National Museum where the bird is now specimen number 531666. The subspecies normally ranges from southcentral Texas and the Yucatan Peninsula south through Central America to Panama (Check-list of North American birds, fifth ed., Baltimore, Amer. Ornithol. Union, 1957, p. 542). This Gainesville specimen apparently is the first Bronzed Cow- bird taken in Florida. Alexander Sprunt, Jr., (Florida bird life. In Addendum to Florida bird life, New York, Coward-McCann, 1963, p. 18) lists three photographed sightings at Sarasota, Florida, in April 196

  2. Cannabis - from cultivar to chemovar.

    Hazekamp, A; Fischedick, J T

    2012-01-01

    The medicinal use of Cannabis is increasing as countries worldwide are setting up official programs to provide patients with access to safe sources of medicinal-grade Cannabis. An important question that remains to be answered is which of the many varieties of Cannabis should be made available for medicinal use. Drug varieties of Cannabis are commonly distinguished through the use of popular names, with a major distinction being made between Indica and Sativa types. Although more than 700 different cultivars have already been described, it is unclear whether such classification reflects any relevant differences in chemical composition. Some attempts have been made to classify Cannabis varieties based on chemical composition, but they have mainly been useful for forensic applications, distinguishing drug varieties, with high THC content, from the non-drug hemp varieties. The biologically active terpenoids have not been included in these approaches. For a clearer understanding of the medicinal properties of the Cannabis plant, a better classification system, based on a range of potentially active constituents, is needed. The cannabinoids and terpenoids, present in high concentrations in Cannabis flowers, are the main candidates. In this study, we compared cultivars obtained from multiple sources. Based on the analysis of 28 major compounds present in these samples, followed by principal component analysis (PCA) of the quantitative data, we were able to identify the Cannabis constituents that defined the samples into distinct chemovar groups. The study indicates the usefulness of a PCA approach for chemotaxonomic classification of Cannabis varieties.

  6. Plant volatile-induced aphid resistance in barley cultivars is related to cultivar age.

    PubMed

    Kellner, Martin; Brantestam, Agnese Kolodinska; Ahman, Inger; Ninkovic, Velemir

    2010-10-01

    Recent studies have shown that volatile chemical interaction between certain barley (Hordeum vulgare) cultivars can cause reduced host plant acceptance by the aphid Rhopalosiphum padi, and that certain cultivars can induce this effect while others can respond. In this study, we tested whether inducing and responding capabilities are linked to year of release in Swedish two-rowed spring barley. Eighteen cultivars released between 1897 and 1992 were tested in randomly selected subsets with pairwise combinations of volatile emitters and receivers. Significantly reduced aphid acceptance as a result of exposure to volatiles from plants of a different cultivar were found in 24% of the cultivar combinations. In general, older cultivars had a higher degree of aphid resistance after barley volatile treatment than did younger cultivars. The inducing effect of the emitter was also related to date of emitter cultivar release but the time relationship was reversed. Combinations with a younger volatile emitter and an older volatile receiver gave the strongest reduction in aphid acceptance of treated plants. Linear relationships between microsatellite diversity of emitting cultivars and their efficiency as inducers indicated that younger cultivars might have a more unique odour, whereas older cultivars may be more sensitive to induction.

    The present study reports the contemporary deformation of the tectonically complex northeast India using 11 years (2002-2013) of GPS observations. The central Shillong Plateau and few sites north of Plateau located in Assam Valley behave like a rigid block with 7 mm/year India-fixed southward velocity. The Euler pole of rotation of this central Shillong Plateau-Assam Valley (SH-AS) block is estimated to be at -25.1° ± 0.2°N, -97.8° ± 1.8°E with an angular velocity of 0.533° ± 0.10° Myr-1 relative to India-fixed reference frame. Kopili fault located between Shillong Plateau and Mikir massif records a dextral slip of 4.7 ± 1.3 mm/year with a locking depth of 10.2 ± 1.4 km indicating the fragmentation of Assam Valley across the fault. Presently, western edge of Mikir massif appears to be locked to Assam block indicating strain accumulation in this region. First-order elastic dislocation modelling of the GPS velocities estimates a slip rate of 16 mm/year along the Main Himalayan Thrust in Eastern Himalaya which is locked over a width of 130 km from the surface to a depth of 17 km with underthrusting Indian plate. Around 9 mm/year arc-normal convergence is accommodated in Lesser Himalaya just south of Main Central Thrust indicating high strain accumulation. Out of 36 mm/year (SSE) India-Sunda plate motion, about 16 mm/year motion is accommodated in Indo-Burmese Fold and Thrust Belt, both as normal convergence ( 6 mm/year) and active slip ( 7-11 mm/year) in this region.

    A significant number of children die each year from acute respiratory tract infections especially in developing countries. Human respiratory syncytial virus (RSV) is the most common virus identified in such cases. Genetic characterization and the circulation pattern of RSV is important for future selection of appropriate vaccine strains. Limited information is available on the circulation of RSV in developing countries including India. The present study aimed to provide baseline information on the genetic variability of RSV in the Dibrugarh district of Assam, northeast India. Clinical specimens collected from children aged ≤6 years for routine influenza surveillance in the Dibrugarh district of Assam during the period 2009-2012, were screened for RSV by real-time reverse transcription-polymerase chain reaction. Genotyping was based on partial sequencing of the RSV attachment glycoprotein gene. RSV was detected in 7.9% (39/493) of cases. Only RSV group A viruses were detected during the study period with predominance of NA1 genotypes (89%). Two RSV GA5 genotypes were found to be co-circulating during 2012. The specific amino acid substitutions characteristics of the NA1 genotypes were distinct from RSV strains reported from the rest of India. It is concluded that the circulating genotypes of RSV in Assam, northeast India are NA1 and GA5. To our knowledge this is the first report of circulation of the NA1 genotype in India.

    Florida posseses climatic, land, and water resources favorable for abundant biomass production. Therefore, a statewide program has been initiated to determine adapted species for the available array of production sites. Plant resources under investigation include woody, aquatic, grasses, hydrocarbon, and root crop species. The goal is to produce a continuous stream of biomass for the various biofuel conversion options. Preliminary yields from energy cropping experiments range from about 10 to nearly 90 metric tons per hectare per year, depending on the crop and the production systems employed. (Refs. 15).

    NASA Technical Reports Server (NTRS)

    2000-01-01

    Multi-angle Imaging SpectroRadiometer (MISR) images of Florida acquired on April 9, 2000 during Terra orbit 1650. The image at the top is a color view acquired by the vertical (nadir) camera. It has been reoriented so that the flight path is from left to right, to facilitate comparison with the lower image, a stereo 'anaglyph' generated using 275-m resolution red band data from the cameras viewing 45.6 degrees and 70.5 degrees aft of nadir. The anaglyph provides a three-dimensional effect when viewed using red/blue glasses with the red filter placed over the left eye. This stereoscopic 'depth perception' and the variation in brightness as a function of view angle enables scientists to assess the climate impact of different types of cloud fields. The plume from a large brush fire that burned about 15,000 acres is visible at the western edge of the Big Cypress Swamp in southern Florida. East is toward the top.

    MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

    The Florida Footprint experiments were a series of field programs in which perfluorocarbon tracers were released in different configurations centered on a flux tower to generate a data set that can be used to test transport and dispersion models. These models are used to determine the sources of the CO{sub 2} that cause the fluxes measured at eddy covariance towers. Experiments were conducted in a managed slash pine forest, 10 km northeast of Gainesville, Florida, in 2002, 2004, and 2006 and in atmospheric conditions that ranged from well mixed, to very stable, including the transition period between convective conditions at midday to stable conditions after sun set. There were a total of 15 experiments. The characteristics of the PFTs, details of sampling and analysis methods, quality control measures, and analytical statistics including confidence limits are presented. Details of the field programs including tracer release rates, tracer source configurations, and configuration of the samplers are discussed. The result of this experiment is a high quality, well documented tracer and meteorological data set that can be used to improve and validate canopy dispersion models.

    Florida (USA), particularly the southern portion of the State, is in a precarious situation concerning arboviral diseases. The geographic location, climate, lifestyle, and the volume of travel and commerce are all conducive to arbovirus transmission. During the last decades, imported dengue cases have been regularly recorded in Florida, and the recent re-emergence of dengue as a major public health concern in the Americas has been accompanied by a steady increase in the number of imported cases. In 2009, there were 28 cases of locally transmitted dengue in Key West, and in 2010, 65 cases were reported. Local transmission was also reported in Martin County in 2013 (29 cases), and isolated locally transmitted cases were also reported from other counties in the last five years. Dengue control and prevention in the future will require close cooperation between mosquito control and public health agencies, citizens, community and government agencies, and medical professionals to reduce populations of the vectors and to condition citizens and visitors to take personal protection measures that minimize bites by infected mosquitoes.

    Tuberculosis (TB) is one of the major public health concerns in Assam, a remote state located in the northeastern (NE) region of India. The present study was undertaken to explore the circulating genotypes of Mycobacterium tuberculosis complex (MTBC) in this region. A total of 189 MTBC strains were collected from smear positive pulmonary tuberculosis cases from different designated microscopy centres (DMC) from various localities of Assam. All MTBC isolates were cultured on Lowenstein-Jensen (LJ) media and subsequently genotyped using spoligotyping and 24-loci mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR) typing. Spoligotyping of MTBC isolates revealed 89 distinct spoligo patterns. The most dominant MTBC strain belonged to Beijing lineage and was represented by 35.45% (n = 67) of total isolates, followed by MTBC strains belonging to Central Asian-Delhi (CAS/Delhi) lineage and East African Indian (EAI5) lineage. In addition, in the present study 43 unknown spoligo patterns were detected. The discriminatory power of spoligotyping was found to be 0.8637 based on Hunter Gaston Discriminatory Index (HGDI). On the other hand, 24-loci MIRU-VNTR typing revealed that out of total 189 MTBC isolates from Assam 185 (97.9%) isolates had unique MIRU-VNTR profiles and 4 isolates grouped into 2 clusters. Phylogenetic analysis of 67 Beijing isolates based on 24-loci MIRU-VNTR typing revealed that Beijing isolates from Assam represent two major groups, each comprising of several subgroups. Neighbour-Joining (NJ) phylogenetic tree analysis based on combined spoligotyping and 24-loci MIRU-VNTR data of 78 Non-Beijing isolates was carried out for strain lineage identification as implemented by MIRU-VNTRplus database. The important lineages of MTBC identified were CAS/CAS1_Delhi (41.02%, n = 78) and East-African-Indian (EAI, 33.33%). Interestingly, phylogenetic analysis of orphan (23.28%) MTBC spoligotypes revealed that majority of these orphan

    The development of Casparian strips (CSs) on the endo- and exodermis and their chemical components in roots of three cultivars of rice (Oryza sativa) with different salt tolerance were compared using histochemistry and Fourier transform infrared (FTIR) spectroscopy. The development and deposition of suberin lamellae of CSs on the endo- and exodermis in the salt-tolerant cultivar Liaohan 109 was earlier than in the moderately tolerant cultivar Tianfeng 202 and the sensitive cultivar Nipponbare. The detection of chemical components indicated major contributions to the structure of the outer part from aliphatic suberin, lignin and cell wall proteins and carbohydrates to the rhizodermis, exodermis, sclerenchyma and one layer of cortical cells in series (OPR) and the endodermal Casparian strip. Moreover, the amounts of these major chemical components in the outer part of the Liaohan 109 root were higher than in Tianfeng 202 and Nipponbare, but there was no distinct difference in endodermal CSs among the three rice cultivars. The results suggest that the exodermis of the salt-tolerant cultivar Liaohan 109 functions as a barrier for resisting salt stress. PMID:21248477

    Popcorn cultivars were evaluated in field and greenhouse tests for resistance to the Columbia root-knot nematode, Meloidogyne chitwoodi, as potential resistant crops in potato rotations. A nematode reproductive factor (Rf) was calculated for each cultivar. Reproductive factor values also were compared on a relative basis as percentages of the Rf on a susceptible field corn standard, Pioneer 3578. Popcorn cultivars W206 and Robust 33-77 consistently supported low population densities of M. chitwoodi in repeated tests. However, WOC 9508 had the greatest resistance in any of the field tests, with an Rf value of 0.04. Cultivars with a mean field and greenhouse Rf value less than 50% of the value for Pioneer 3578 were WOC 9508 (8%), WOC 9554 (13%), W206 (15%), WOX 9512 (23%), Robust 33-77 (30%), Robust 20-70 (38%), WOC 9510 (41%), and WOC 9504 (42%). If these cultivars were used in rotation, M. chitwoodi population densities at the end of the popcorn season would be between 58% and 92% less than if Pioneer 3578 were grown. In greenhouse tests, WOX 9511, WOX 9528, WOC 9556, and WOX 9531 also had low Rf values (7-46% that of Pioneer 3578), but field testing of these cultivars is needed. PMID:19274265

  14. Seismic landscape from Sarpang re-entrant, Bhutan Himalaya foredeep, Assam, India: Constraints from geomorphology and geology

    Geomorphic landscape and late Quaternary geological attributes from the Raidak-Manas interfluve in the Bhutan-Himalayan foothills, Kokrajhar District, Assam led towards documenting the east-west trending, south dipping, 30 km long active Frontal Back Thrust (FBT), well within the foredeep south of the Main Frontal Thrust (MFT). Spectacular north facing 6-50 m high tectonic-scarp generated by the north-propagating emerging thrust front along with a complementary subdued south-facing scarp defines the terrain as a pop-up structure. The entire belt is made up of 5 to 8 km wide six distinct blocks, separated by antecedent rivers/streams. Scarp parallel east-west drainage along with linear lakes characterises the emerging thrust front. Field evidence for a major fault-propagation fold structure along with thrust faulting within the late-Quaternary fluvial sediments is ubiquitous. Clay beds deposited in lakes along the footwall of FBT have formed due to blockade of south flowing rivers by episodic upliftment of the hanging wall block; three such episodes of uplift since 16 k years correspond to three morphogenic earthquakes of magnitude ~ 6.9 rupturing the FBT during late Pleistocene-Holocene. In light of geomorphological and geological studies, neotectonic activity has been modelled as an active south dipping backthrust that originates at shallow crustal depth from south vergent basal Himalayan Decollement in response to the advancing Himalayan wedge.

    The objectives of this research were to investigate the antioxidant effect of Assam tea extract (ATE) and whether it is fit to utilise ATE by fortification in rice bran breakfast cereal (RBC). The increasing ATE powder from 0.1 to 0.3mg/g affected to be decreased. The ATE powder at 0.3mg/g was proved to have decreased the hexanal content (0.21μg/ml) and thiobarbituric acid reactive substances (TBARS) (2.56μg/g) within 28days, and provided the highest antioxidant ability (EC50) (2481.44mg/kg). The fortified 0.3mg/g of ATE powder showed that increasing ATE significantly increased the total phenolic content and decreased TBARS and EC50 of breakfast cereal (p<0.05). The suitable amount ATE powder added in RBC was 0.5%. The consumer acceptance (n=200) of final product showed the sensory scores in the range of 6.3-6.8, with the percentages of acceptance and purchase intention at 98.0% and 89.0%, respectively.

    A bacterial strain designated as BPM3 isolated from mud of a natural hot water spring of Nambar Wild Life Sanctuary, Assam, India, strongly inhibited growth of phytopathogenic fungi (Fusarium oxysporum f. sp. ciceri, F. semitectum, Magnaporthe grisea and Rhizoctonia oryzae) and gram-positive bacterium (Staphylococcus aureus). The maximum growth and antagonistic activity was recorded at 30°C, pH 8.5 when starch and peptone were amended as carbon and nitrogen sources, respectively. In greenhouse experiment, this bacterium (BPM3) suppressed blast disease of rice by 30-67% and protected the weight loss by 35-56.5%. The maximum disease protection (67%) and weight loss protection (56.5%) were recorded when the bacterium was applied before 2 days of the pathogen inoculation. Antifungal and antibacterial compounds were isolated from the bacterium which also inhibited the growth of these targeted pathogens. The compounds were purified and on spectroscopic analysis of a purified fraction having R(f) 0.22 which showed strong antifungal and antibacterial activity indicated the presence of C-H, carbonyl group, dimethyl group, -CH(2) and methyl group. The bacterium was characterized by morphological, biochemical and molecular approaches and confirmed that the strain BPM3 is Brevibacillus laterosporus.

    2013-08-01

    In the present study the occurrence of two heavy metals, arsenic and cadmium, have been reported in the drinking water and seminal plasma of infertile male patients as compared to a control group. The study originated from a survey of geogenic groundwater contamination with the heavy metals arsenic and cadmium in Southern Assam, India as an increase in the incidence of male infertility was being reported from these areas. According to WHO protocol, patients with sperm concentration < 20 x 10(6)/ml were selected as cases (oligozoospermic and azoospermic), and those with > 20 x 10(6)/ml, without any extreme pathological disorders and having fathered a child within 1-2 years of marriage were the control (normozoospermic) group. The study reports an inverse relationship between total sperm count and heavy metal content in drinking water as well as seminal plasma of the subjects. Moreover, a high correlation between altered semenological parameters and lower expression of accessory sex gland markers like fructose, acid phosphatase, and neutral α-glucosidase in the seminal plasma of patients is reported. The study also highlights significant differences of the sperm function parameters like hypo-osmotic swelling, acrosome reaction, and nuclear chromatin decondensation in the patient group as compared to controls. These findings are significant as they address a likely association between heavy metal stress and altered sperm function as well as seminal enzyme inhibition.

    2013-09-01

    Groundwater in the Brahmaputra river basin is known to contain an elevated concentration of naturally occurring Arsenic (As). To better understand the mobilization processes responsible for the As enrichment in the groundwater of the alluvial plains of the Brahmaputra river, the hydrochemical characteristics of the groundwater were studied in two districts, namely the Darrang and Jorhat districts of Assam. A total of 217 groundwater samples were analyzed for 20 water quality parameters. A lower As concentration was observed in the Darrang district with a mean concentration of 0.02 μg l(-1), while the Jorhat district had a higher As concentration (mean 100 μg l(-1)). The groundwater in the study areas is characterized by high concentrations of dissolved Fe, Mn, HCO3(-) and PO4(3-) and low concentrations of NO3(-) and SO4(2-). The redox potential and the groundwater composition showed reducing conditions in the groundwater. A difference in the groundwater geochemistry between the two districts was observed and was mainly controlled by the redox conditions in the subsurface, which control the mobility of As in the floodplains. The saturation indices of various As associated minerals were calculated using the geochemical code PHREEQC. The mobilization of As into the groundwater was anticipated to be largely controlled by the reductive dissolution of Fe-oxides and Mn-oxides and partly by competitive anions viz. PO4(3-).

    We present crustal anisotropy estimates constrained by shear wave splitting (SWS) analysis using local earthquakes in the Shillong plateau and Assam valley area, North East India (NE India) region. Splitting parameters are determined using an automated cross-correlation (CC) method. We located 330 earthquakes recorded by 17 broadband seismic stations during 2001-2014 in the study area. Out of these 330 events, seismograms of 163 events are selected for the SWS analysis. Relatively small average delay times (0.039-0.084 s) indicate existence of moderate crack density in the crust below the study area. It is found that fast polarization directions vary from station to station depending on the regional stress system as well as geological conditions. The spatial pattern of crustal anisotropy in the area is controlled mostly by tectonic movement of the Indian plate towards NE. Presence of several E-W and N-S trending active faults in the area also play an important role on the observed pattern of crustal anisotropy.

    Amongst host genetic factors, cytokine gene polymorphism can be anticipated to be an important factor as qualitative, quantitative and time of secretion play an important role in disease outcome. We have investigated association of cytokine promoter SNPs with risk of Plasmodium falciparum malaria and disease severity in a case control study in malaria endemic Karbi Anglong district of Assam, India. Frequency of IL-8-251T/A (p=0.03 and p=0.01) and TGF-β1-509C/T (p=0.02 and p=0.03) was higher in malaria in comparison to control participants and non-malarial fever controls. Interestingly, a higher frequency of mutant allele of IL-10-819T/C was observed in non-malarial fever controls compared to malaria thus suggesting its role as a distinguishing marker of the two disease groups. Higher IL-8 expression and increased frequency of IL-8-251T/A in complicated malaria (p=0.002) was reported indicating its role in susceptibility to complicated malaria. In conclusion, our study suggests the role of mutant genotype of IL-8-251T/A as a marker of complicated malaria in our population. Surprisingly, decreased expression of TGF-β1 in uncomplicated malaria even in presence of high expressing mutant genotype was observed and needs to be investigated in context of the pool of activated cells producing the cytokine.

    This is the first report on the microbial diversity of xaj-pitha, a rice wine fermentation starter culture through a metagenomics approach involving Illumine-based whole genome shotgun (WGS) sequencing method. Metagenomic DNA was extracted from rice wine starter culture concocted by Ahom community of Assam and analyzed using a MiSeq(®) System. A total of 2,78,231 contigs, with an average read length of 640.13 bp, were obtained. Data obtained from the use of several taxonomic profiling tools were compared with previously reported microbial diversity studies through the culture-dependent and culture-independent method. The microbial community revealed the existence of amylase producers, such as Rhizopus delemar, Mucor circinelloides, and Aspergillus sp. Ethanol producers viz., Meyerozyma guilliermondii, Wickerhamomyces ciferrii, Saccharomyces cerevisiae, Candida glabrata, Debaryomyces hansenii, Ogataea parapolymorpha, and Dekkera bruxellensis, were found associated with the starter culture along with a diverse range of opportunistic contaminants. The bacterial microflora was dominated by lactic acid bacteria (LAB). The most frequent occurring LAB was Lactobacillus plantarum, Lactobacillus brevis, Leuconostoc lactis, Weissella cibaria, Lactococcus lactis, Weissella para mesenteroides, Leuconostoc pseudomesenteroides, etc. Our study provided a comprehensive picture of microbial diversity associated with rice wine fermentation starter and indicated the superiority of metagenomic sequencing over previously used techniques.

    Drinking water quality with respect to lead, iron, fluoride, and arsenic has been carried out in and around tea gardens of Darrang district of Assam, India. The district lies between 26 degrees 25(') and 26 degrees 55(') northern latitude and 91 degrees 45(') and 91 degrees 20(') east longitude and covers an area of 3,465.30 km(2). Twenty-five different sampling stations were selected for the study. Iron, lead, and arsenic were analyzed by using an atomic absorption spectrometer, Perkin Elmer AA 200, while fluoride was measured by the SPADNS method using a UV-VIS spectrometer, Shimadzu 1240 model. The study revealed that the water sources in the area are heavily polluted with lead. Statistical analysis of the data is presented to determine the distribution pattern, localization of data, and other related information. Statistical observations imply non-uniform distribution of the studied parameters with a long asymmetric tail either on the right or left side of the median.

    The study is aimed at the remediation of soil spiked with crude oil (5%) by employing Fenton oxidation, biological treatment and combined Fenton-biological treatment. A spiked concentration of 5% crude oil was selected on the basis of contamination levels of 0-5% as found in the soil of upper Assam oil fields (India). The degradation of the aliphatic fraction (C14-C28) of the crude oil was investigated by gas chromatography. Fenton oxidation was carried out at different pH (3 to 8) in a laboratory batch reactor and maximum oxidative degradation was observed at pH 3-5. At pH 3, single Fenton oxidation resulted in 36 and 57% degradation in 5 and 10 days respectively. Biological treatment (with Fusarium solani) and combined Fenton-biological treatment were carried out with a one month incubation period. Biological treatment alone brought about 61% degradation of the crude oil while the combined process could achieve as much as 75% degradation of the aliphatic fractions of the crude oil.

    The morphological variations of the thyroid gland have been reported from different parts of the world. The variations are due to remnant or non-specific development of the parts of the thyroid gland. Surgical operation of the thyroid gland has been the treatment of choice in various thyroid pathologies. Prior knowledge of the morphological variation is important to ensure better results from these surgical operations. To study the prevalence of morphological variations seen in the thyroid glands in the upper Assam region of Northeast India. This was a hospital based cadaveric study. Total number of Thyroid glands dissected were 80. The thyroid gland was examined properly for the presence of pyramidal lobe, levator glandulae thyroideae and complete absence of isthmus. Statistical analysis was done by SPSS 21.0. It was found that 17 (21.25%) cadavers did not show an isthmus. The pyramidal lobe was present in 31(38.75%) cases and frequently arising from the left side (74.2%) of the isthmus. Levator glandulae thyroideae was found in 15 (18.75%) of the thyroid specimens. In all cases, it was extended from the apex of the pyramidal lobe to the hyoid bone. Morphological variation of the thyroid gland is very common hence requires detection prior to any surgery on the thyroid gland.

    In Florida, southern highbush (SHB) blueberries (Vaccinium corymbosum L. x Vaccinium darrowi Camp) are grown for a highly profitable early season fresh market. Flower thrips are the key pest of SHB blueberries, and Frankliniella bispinosa (Morgan) is the most common species found. Flower thrips injure blueberry flowers by feeding and ovipositing in all developing tissues. These injuries can lead to scarring of developing fruit. The objectives of this study were to determine the relationship between thrips and yield in different SHB blueberry cultivars and to determine an action threshold. Experiments were conducted during early spring 2007 and 2008 on four farms; a research farm in Citra, FL; and three commercial farms, two in Hernando Co., FL., and one in Lake Co., FL. At the Citra farm, 'Emerald', 'Jewel', 'Millennia', and 'Star' blueberries were compared in 2007, and all but Star were compared in 2008. On the Hernando and Lake Co. farms, two treatment thresholds (100 and 200 thrips per trap) and an untreated control and four cultivars (Emerald, Jewel, Millennia, and 'Windsor') were compared. Emerald consistently had more thrips per trap and per flower than the other cultivars on all four farms. However, this did not always lead to an increase in fruit injury. Thrips numbers exceeded the threshold on only one farm in 2007, and there was a significantly lower proportion of injured and malformed fruit in the 100 thrips per trap threshold treatment compared with the control on this farm.

    The genetic relationships among 27 pineapple [Ananas comosus (L.) Merr.] cultivars and lines were examined using 16 simple sequence repeat (SSR) markers. The number of alleles per locus of the SSR markers ranged from 2 to 6 (average 3.19), for a total of 51 alleles. Similarity coefficients were calculated on the basis of 51 amplified bands. A dendrogram was created according to the 16 SSR markers by the unweighted pair-group method. The banding patterns obtained from the SSR primers allowed most of the cultivars and lines to be distinguished, with the exception of vegetative clones. According to the dendrogram, the 27 pineapple cultivars and lines were clustered into three main clusters and four individual clusters. As expected, the dendrogram showed that derived cultivars and lines are closely related to their parental cultivars; the genetic relationships between pineapple cultivars agree with the genealogy of their breeding history. In addition, the analysis showed that there is no obvious correlation between SSR markers and morphological characters. In conclusion, SSR analysis is an efficient method for pineapple cultivar identification and can offer valuable informative characters to identify pineapple cultivars in Taiwan.

    Peak daily pumpage from the highly permeable, unconfined Biscayne aquifer for public water-supply systems in southeast Florida in 1975 was about 500 million gallons. Another 165 million gallons was withdrawn daily for irrigation. Recharge to the aquifer is primarily by local rainfall. Discharge is by evapotranspiration, canal drainage, coastal seepage, and pumping. Pollutants can enter the aquifer by direct infiltration from land surface or controlled canals, septic-tank and other drainfields, drainage wells, and solid-waste dumps. Most of the pollutants are concentrated in the upper 20 to 30 feet of the aquifer; public supply wells generally range in depth from about 75 to 150 feet. Dilution, dispersion, and adsorption tend to reduce the concentrations. Seasonal heavy rainfall and canal discharge accelerate ground-water circulation, thereby tending to dilute and flush upper zones of the aquifer. The ultimate fate of pollutants in the aquifer is the ocean, although some may be adsorbed by the aquifer materials en route to the ocean, and some are diverted to pumping wells. (Woodard-USGS)

  12. Andrew spares Florida Coast

    When geologists heard of the intensity of Hurricane Andrew, which struck the Florida coast on August 25 and then moved on to southern Louisiana, they were expecting the same kinds of coastal damage that Hurricane Hugo brought to the Caribbean and Carolina shores in 1989. Both storms were category 4 hurricanes, having winds of 131-155 mph and surges of 13-18 feet. However, the coastal damage never materialized, leaving geologists to analyze the factors that lessened the impact of the storm. “For minimum coastal damage, you couldn't have designed a better storm,” said Orrin Pilkey, director of the Program for the Study of Developed Shorelines (PSDS) in Durham, N.C. This was due in part to the nature of the storm itself and where it hit land, and in part to the regional geology, said Rob Thieler of PSDS. Despite the huge amounts of damage to buildings, there was virtually no evidence of coastal process destruction, he said.

    In recent years, heavy metal pollution in agricultural soil in China has received public concern. The concept of low-accumulation cultivars (LACs) was proposed to minimize the influx of pollutants to the human food chain. Variations in Cd and Pb accumulation, distribution, and tolerance among 30 wheat (Triticum aestivum L.) cultivars were studied in a hydroponic experiment to preliminary identify LACs of Cd or Pb for further field experiments. Of the 30 wheat cultivars tested, 27 and 26 wheat cultivars showed no effect of the Cd/Pb treatments on the shoot and root biomass, respectively. The results showed that the tested wheat cultivars had considerable tolerance to Cd and Pb toxicity. Significant (p < 0.05) differences in shoot Cd concentration were observed among the tested wheat cultivars under treatments Cd1.0 and Cd1.0Pb15, ranging from 0.91 to 6.74 and from 0.87 to 5.96, with the mean of 3.83 and 2.94 mg kg(-1) DW, respectively. Significant (p < 0.05) differences in shoot Pb concentration were also observed among the tested wheat cultivars under treatments Pb15 and Cd1.0Pb15, ranging from 22.18 to 94.03 and from 18.30 to 76.88, with the mean of 50.38 and 41.20 mg kg(-1) DW, respectively. Low accumulation and internal distribution may both affect the cultivar differences in Cd and Pb accumulation in wheat shoots. Overall, wheat cultivars LF-13, LF-16, and LF-21 had lower Cd-accumulating abilities in their shoots. Wheat cultivars LF-13, LF-23, LF-26, and LF-27 showed low Pb accumulation characteristics in their shoots. An antagonistic interaction occurred between Cd and Pb in accumulation in wheat roots and shoots, which will be further studied in field experiments.

    ABSTRACT Alternaria spp. were sampled from brown spot lesions in several geographically separated citrus groves and different grapefruit and tangerine x grapefruit hybrid cultivars in Florida and screened for variation at 16 putative random amplified polymorphic DNA loci. Populations of the pathogen on two hybrids, Minneola and Orlando, in five locations throughout Florida were moderately differentiated (Nei's coefficient of gene differentiation [G(ST)] = 0.12) among locations. The hypothesis that host-specialized forms of Alternaria spp. cause brown spot on different Citrus spp. and cultivars was tested by estimating genetic differentiation among isolates sampled from different hosts and by pathogenicity assays. Isolates sampled from grapefruit and the hybrid cv. Nova were genetically distinct from isolates sampled from other hybrid cultivars including Robinson, Sunburst, Minneola, Orlando, and Murcott. No differentiation could be detected among isolates sampled from this latter group of hybrids. Quantitative pathogenicity assays on leaves using spray inoculation revealed that 'Nova' isolates were not significantly more pathogenic on 'Nova' compared with isolates from 'Minneola' and 'Orlando'. Similarly, grapefruit isolates were not significantly more pathogenic on grapefruit compared with isolates from 'Minneola'. Isolates from all hosts had similar disease rankings on each inoculated cultivar, with 'Minneola' the most susceptible, followed in decreasing order of susceptibility by 'Orlando', 'Sunburst', 'Nova', and 'Duncan' grapefruit. Rough lemon was generally immune to all isolates tested; however, occasional brown spot lesions were observed on leaves of this host with isolates from grapefruit. No evidence was found to support the hypothesis that unique genotypes of the pathogen, which are more virulent on 'Sunburst' or grapefruit, have been introduced to Florida.

    Final densities (Pf) of Meloidogyne incognita and Pratylenchus spp. increased more than ten-fold over initial densities (Pi) on corn (Zea mays) cultivars grown at three sites in north Florida. The Pf of M. incognita following sorghum (Sorghum bicolor) were much lower (P ≤0.001) than Pf following corn at the two sites in which sorghum was grown. At one of these sites, Pf of M. incognita was ≤ 5/100 cm³ soil, and at the other site Pf < Pi. At one site, population densities of Criconemella sphaerocephala increased to higher levels on sorghum than on corn, but Pf of Pratylenchus spp. were greater (P ≤ 0.01) on corn. Few differences in nematode densities were observed among the different corn cultivars tested. PMID:19283182

    A comprehensive risk factor profile of non-communicable diseases (NCDs) as suggested by the World Health Organization (WHO) has not been reported from tribal population in India. This survey was carried out to assess the prevalence of NCD risk factors among Mishing tribes in Assam using the WHO STEPs approach. A total of 332 individuals of the Mishing tribe (men 54%) aged 25-64 yr were selected from Tinsukia district by multistage cluster sampling. Using the WHO STEPs approach information was collected on demographics, STEP 1 variables (tobacco, alcohol, physical activity, diet) and measured STEP 2 variables (weight, height, waist circumference and blood pressure). Multivariate analysis was used to find the relation between STEP 1 and STEP 2 variables. Overall, tobacco use was 84 per cent (men 94%; women 73%, p0 <0.001) and alcohol use was 67 per cent (men 82%; women 50%, p0 <0.05); 86 per cent reported vigorous physical activity, (men 91%, women 82%; p0 < 0.05). Sixty eight per cent reported to consume unhealthy diet (less than five servings of fruits and vegetables/day), 11 per cent had abdominal obesity, 16 per cent were overweight and 26 per cent had hypertension. Non users of tobacco and those who consumed more fruits and vegetables had higher prevalence of overweight ( p0 <0.05). Among the hypertensives, 24 per cent were aware, 17 per cent treated and 2.4 per cent controlled their hypertension. Older individuals had higher hypertension prevalence ( p0 <0.05) compared to younger individuals. Tobacco use, alcohol use and unhealthy diet habits were high among men and women in this population and were major NCD risk factors. An integrated approach of culturally appropriate population level and high risk strategies are warranted to reduce these risk factors and to enhance adequate control of hypertension.

    Diversity of culturable bacterial populations within the Arsenic (As) contaminated groundwater of North Eastern state (Assam) of India is studied. From nine As contaminated samples 89 bacterial strains are isolated. 16S rRNA gene sequence analysis reveals predominance of Brevundimonas (35%) and Acidovorax (23%) along with Acinetobacter (10%), Pseudomonas (9%) and relatively less abundant (<5%) Undibacterium, Herbaspirillum, Rhodococcus, Staphylococcus, Bosea, Bacillus, Ralstonia, Caulobacter and Rhizobiales members. High As(III) resistance (MTC 10-50 mM) is observed for the isolates obtained from As(III) enrichment, particularly for 3 isolates of genus Brevundimonas (MTC 50 mM). In contrast, high resistance to As(V) (MTC as high as 550 mM) is present as a ubiquitous property, irrespective of isolates' enrichment condition. Bacterial genera affiliated to other groups showed relatively lower degree of As resistance [MTCs of 15-20 mM As(III) and 250-350 mM As(V)]. As(V) reductase activity is detected in strains with high As(V) as well as As(III) resistance. A strong correlation could be established among isolates capable of reductase activity and siderophore production as well as As(III) tolerance. A large number of isolates (nearly 50%) is capable of anaerobic respiration using alternate inorganic electron acceptors [As(V), Se(VI), Fe(III), [NO(3)(2), SO(4)(2), S(2)O(3)(2). Ability to utilize different carbon sources ranging from C2-C6 compounds along with some complex sugars is also observed. Particularly, a number of strains is found to possess ability to grow chemolithotrophically using As(III) as the electron donor. The study reports for the first time the identity and metabolic abilities of bacteria in As contaminated ground water of North East India, useful to elucidate the microbial role in influencing mobilization of As in the region.

    The great Assam earthquake (08/15/1950, Mw.8.7) shook border regions between northeastern Indian, Tibet, and China for several minutes, triggering large landslides and numerous aftershocks over a wide area in the Abor and Mishmi Hills. Using morpho-tectonic field observations and high-resolution satellite images analysis we show that the earthquake produced a >200 km-long surface rupture along the Eastern Himalayan Syntaxis. It ruptured both the Main Himalayan Frontal Thrust (MFT) and the Mishmi Thrust (MST) all the way to the surface, producing clear tectonic scarps cutting Quaternary alluvial terrace risers at high angle. We analyse the geometry, height, shape, and slopes of these scarps with high-resolution topographic profiles levelled using Total Station and kinematic GPS, to document 1950 co-seismic and older cumulative surface uplifts. The co-seismic vertical throws differ between the two thrusts from ≈ 7 m and ≈ 3 m, along the MST and MFT, respectively. We stack series of parallel topographic profiles extracted from high-resolution data (eg. ALOS and Pleiades) to document the morphology of uplifted Quaternary alluvial terraces in order to identify past earthquakes. Our results show occurrence of 2 and 6 past earthquakes, along the MST and the MFT, respectively. We combine these results with radiocarbon and cosmogenic dating to assess the ages of these uplifted surfaces and constrain uplift rates of 3 ± 1 mm/yr on both thrusts and a recurrence interval of 1500 ± 300 yr between large events along the Eastern Himalayan Syntaxis. We discuss the possibility that our results suggest characteristic slip along both thrusts through Quaternary time scale.

    India is an important non-breeding ground for migratory waterfowl in the Central Asian Flyway. Millions of birds visit wetlands across the country, yet information on their distribution, abundance, and use of resources is rudimentary at best. Limited information suggests that populations of several species of migratory ducks are declining due to encroachment of wetland habitats largely by agriculture and industry. The development of conservation strategies is stymied by a lack of ecological information on these species. We conducted a preliminary assessment of the home range and habitat use of Ruddy Shelduck Tadorna ferruginea in the northeast Indian state of Assam. Seven Ruddy Shelducks were fitted with solar-powered Global Positioning System (GPS) satellite transmitters, and were tracked on a daily basis during the winter of 2009-2010. Locations from all seven were used to describe habitat use, while locations from four were used to quantify their home range, as the other three had too few locations (2 (range = 22-87 km2) and an average home range (95% contour) of 610 km2 (range = 222-1,550 km2). Resource Selection Functions (RSF), used to describe habitat use, showed that the birds frequented riverine wetlands more than expected, occurred on grasslands and shrublands in proportion to their availability, and avoided woods and cropland habitats. The core use areas for three individuals (75%) were on the Brahmaputra River, indicating their preference for riverine habitats. Management and protection of riverine habitats and nearby grasslands may benefit conservation efforts for the Ruddy Shelduck and waterfowl species that share these habitats during the non-breeding season.

    Japanese encephalitis (JE) is one of the dreaded mosquito-borne viral diseases mostly prevalent in south Asian countries including India. Early warning of the disease in terms of disease intensity is crucial for taking adequate and appropriate intervention measures. The present study was carried out in Dibrugarh district in the state of Assam located in the northeastern region of India to assess the accuracy of selected forecasting methods based on historical morbidity patterns of JE incidence during the past 22 years (1985-2006). Four selected forecasting methods, viz. seasonal average (SA), seasonal adjustment with last three observations (SAT), modified method adjusting long-term and cyclic trend (MSAT), and autoregressive integrated moving average (ARIMA) have been employed to assess the accuracy of each of the forecasting methods. The forecasting methods were validated for five consecutive years from 2007-2012 and accuracy of each method has been assessed. The forecasting method utilising seasonal adjustment with long-term and cyclic trend emerged as best forecasting method among the four selected forecasting methods and outperformed the even statistically more advanced ARIMA method. Peak of the disease incidence could effectively be predicted with all the methods, but there are significant variations in magnitude of forecast errors among the selected methods. As expected, variation in forecasts at primary health centre (PHC) level is wide as compared to that of district level forecasts. The study showed that adopted forecasting techniques could reasonably forecast the intensity of JE cases at PHC level without considering the external variables. The results indicate that the understanding of long-term and cyclic trend of the disease intensity will improve the accuracy of the forecasts, but there is a need for making the forecast models more robust to explain sudden variation in the disease intensity with detail analysis of parasite and host population

    Objectives: The aim of this study is to evaluate the prescribing pattern of analgesics and analyze the rational use of analgesic in orthopedic in-patient department of tertiary care teaching hospital, Guwahati, Assam. Subjects and Methods: An observational and cross-sectional study was carried out for 1 month from April to May 2014. Collected data included age, sex, diagnosis and line of management during the study. The generic name and the average cost of treatment per patient were evaluated using Indian Drug Review, 2014. The prescribed drugs were assessed with respective National Model List of Essential Medicines (NLEM), 2011 and the rationality of prescriptions was determined using the World Health Organization indicators of drug utilization. The patients’ details were recorded in a predeigned data collection form and results were analyzed by descriptive statistics. Results: Out of 200 patients, 123 were male and 77 were female. The average number of analgesic per prescription was 1.46. In this study, 55.5% of patients had received single analgesic. Diclofenac was the most commonly prescribed analgesic (43.49%). During hospitalization, majority of the patients have received parenteral preparation. Gastroprotective agents and antimicrobials were frequently prescribed along with analgesics. Out of 292 analgesics prescribed, 183 (62.67%) were from the NLEM, India. Furthermore, 176 (57.19%) analgesics were prescribed by generic name. The average cost of treatment per patient was 2151.72 INR. Utilization of analgesic in terms of defined daily dose/100 bed-days was 104.01. Conclusion: The percentages of analgesics prescribing from NLEM and the use of analgesic by generic name were found satisfactory. Regular educational interventions to improve prescribing practices among physicians at different levels may further promote rational prescribing. PMID:27756947

Out of 292 analgesics prescribed, 183 (62.67%) were from the NLEM, India. Furthermore, 176 (57.19%) analgesics were prescribed by generic name. The average cost of treatment per patient was 2151.72 INR. Utilization of analgesic in terms of defined daily dose/100 bed-days was 104.01. The percentages of analgesics prescribing from NLEM and the use of analgesic by generic name were found satisfactory. Regular educational interventions to improve prescribing practices among physicians at different levels may further promote rational prescribing.

    The Kolong River of Nagaon district, Assam has been facing serious degradation leading to its current moribund condition due to a drastic human intervention in the form of an embankment put across it near its take-off point from the Brahmaputra River in the year 1964. The blockage of the river flow was adopted as a flood control measure to protect its riparian areas, especially the Nagaon town, from flood hazard. The river, once a blooming distributary of the mighty Brahmaputra, had high navigability and rich riparian biodiversity with a well established agriculturally productive watershed. However, the present status of Kolong River is highly wretched as a consequence of the post-dam effects thus leaving it as stagnant pools of polluted water with negligible socio-economic and ecological value. The Central Pollution Control Board, in one of its report has placed the Kolong River among 275 most polluted rivers of India. Thus, this study is conducted to analyze the seasonal water quality status of the Kolong River in terms of water quality index (WQI). The WQI scores shows very poor to unsuitable quality of water samples in almost all the seven sampling sites along the Kolong River. The water quality is found to be most deteriorated during monsoon season with an average WQI value of 122.47 as compared to pre-monsoon and post-monsoon season having average WQI value of 85.73 and 80.75, respectively. Out of the seven sampling sites, Hatimura site (S1) and Nagaon Town site (S4) are observed to be the most polluted sites.

    A study was conducted to evaluate the heavy metal contamination status of groundwater in Brahmaputra flood plain Barpeta District, Assam, India. The Brahmaputra River flows from the southern part of the district and its many tributaries flow from north to south. Cd, Fe, Mn, Pb, and Zn are estimated by using atomic absorption spectrometer, Perkin Elmer AA 200. The quantity of heavy metals in drinking water should be checked time to time; as heavy metal accumulation will cause numerous problems to living being. Forty groundwater samples were collected mainly from tube wells from the flood plain area. As there is very little information available about the heavy metal contamination status in the heavily populated study area, the present work will help to be acquainted with the suitability of groundwater for drinking applications as well as it will enhance the database. The concentration of iron exceeds the WHO recommended levels of 0.3 mg/L in about 80% of the samples, manganese values exceed 0.4 mg/L in about 22.5% of the samples, and lead values also exceed limit in 22.5% of the samples. Cd is reported in only four sampling locations and three of them exceed the WHO permissible limit (0.003 mg/L). Zinc concentrations were found to be within the prescribed WHO limits. Therefore, pressing awareness is needed for the betterment of water quality; for the sake of safe drinking water. Statistical analysis of the data was carried out using Special Package for Social Sciences (SPSS 16).

    2015-01-01

    Ciguatera is the most commonly reported marine food-borne illness worldwide. Because there is a biological plausibility that ciguatera may be impacted by long-term climate variability and Florida is on the northern border of the geographic distribution of ciguatera, it is important to update our understanding of its epidemiology in Florida. We performed an analysis of 291 reports in Florida from 2000 to 2011 and an e-mail survey of 5,352 recreational fishers to estimate incidence and underreporting and identify high risk demographic groups, fish types, and catch locations. Incidence was 5.6 per 100,000 adjusted for underreporting. Hispanics had the highest incidence rate (relative risk [RR] = 3.4) and were more likely to eat barracuda than non-Hispanics. The most common catch locations for ciguatera-causing fish were the Bahamas and Florida Keys. Cases caused by fish from northern Florida were infrequent. These results indicate that ciguatera incidence is higher than estimated from public health reports alone. There is little evidence that incidence or geographic range has increased because of increased seawater temperatures since earlier studies. PMID:26123957

  12. Troubled waters: a Florida nightmare

    SciTech Connect

    Cooper, W.

    1984-12-01

    Results of studies of pollution of groundwater in Florida are reported. Vast amounts of the underground water were found to be polluted with ethylene dibromide (EDB) used by Florida farmers since the 1950s as an insecticide. Pollution levels of water in the middle of the citrus belt were found to be as high as 775 ppB when 0.02 ppB has been set by the Florida Agriculture Department as the level for concern. EDB can be removed using activated charcoal filters, or new wells can tap aquifers separated from contaminated ones by beds of impermeable clay. Evidences of contamination of water in specific sites by cresote, sulfuric acid, and heavy metals such as lead and arsenic are mentioned.

    The tectonic model of the Shillong plateau and Assam valley in the northeast India region, the source area for the 1897 great earthquake (Ms ~ 8.7) and for the four (1869, 1923, 1930 and 1943) large earthquakes (M. ≥ 7.0), is examined using the high precision data of a 20-station broadband seismic network. About 300 selected earthquakes M ≥ 3.0 recorded during 2001-2009 are analysed to study the seismicity and fault plane solutions. The dominating thrust/reverse faulting earthquakes in the western plateau may be explained by the proposed pop-up tectonics between two active boundary faults, the Oldham-Brahmaputra fault to the north and the Dapsi-Dauki thrust to the south, though the northern boundary fault is debated. The more intense normal and strike-slip faulting earthquakes in the eastern plateau (Mikir massif) and in the Assam valley, on the other hand, are well explained by transverse tectonics at the long and deep rooted Kopili fault that cuts across the Himalaya and caused the 2009 Bhutan earthquake (Mw 6.3). It is conjectured that the complex tectonics of the Shillong plateau and transverse tectonics at the Kopili fault make the region vulnerable for impending large earthquake(s).

    Cercarial dermatitis of paddy field workers in Assam is very common. However, it is not known which species of animal schistosomes, is its causative agent in Assam. Studies in two dermatitis affected villages of Dibrugarh district revealed that cercariae of Schistosoma spindale were involved in its aetiology. Indoplanorbis exustus was the only snail species found infected with apharyngeate brevifurcate schistosome cercarie. Experimental infection of the laboratory animals with the dermatitis causing schistosome cercariae revealed that duckling and chicken were refractory to infection. However, Swiss albino mice were successfully infected. The number of adult flukes per infected mice ranged from 6-321 (mean intensity = 68.1; S.D. = +/- 112.96). Histopathological study of infected mice liver revealed that there was mild inflammation of infected portal triads towards the presence of male flukes in the intra hepatic portal vessels. Kuppffer cells showed hyperplasia and contained large amounts of black pigment. No eggs or egg granulomas were detected in the liver parenchyma. There was no evidence of thrombophlebitis, septal fibrosis or pipe stem fibrosis.

  15. Maternal and socio-demographic determinants of low birth weight (LBW): A community-based study in a rural block of Assam

    PubMed Central

    Borah, M; Agarwalla, R

    2016-01-01

    Background and Rationale: Low birth weight (LBW) leads to high neonatal and infant deaths. There is also high prevalence of childhood morbidities and mortalities that are consequences of LBW. Objectives: To find out the prevalence of LBW babies among the study population and to find out the effect of certain maternal and socio-demographic characteristics on birth weight. Materials and Methods: This cross-sectional study was carried out in a rural block of Assam. Cluster sampling was done to choose 30 villages and 15 infants were selected randomly from each village to get a sample size of 450. Results: Prevalence of LBW was found to be 21.8%. Percentage of LBW babies was more among the teenage mothers (36%) and primipara mothers (27%). Maternal anemia [odds ratio (OR) 1.93; confidence interval (CI) 1.3-2.9], short interpregnancy interval (OR 3.93; CI 2.16-7.13), and teenage pregnancy (OR 3.93; CI 2.16-6.45) were found to be the independent risk factors associated with LBW of the babies. Discussion: The study findings indicated the high prevalence of LBW babies in rural areas of Assam and illiterate teenage mothers, grand multipara, anemic mothers, and short interpregnancy intervals were the important risk factors for LBW.

    The study aims to ascertain the hypothesis on the rich rotifer biodiversity of the floodplain lakes (beels) of the Brahmaputra river basin and to use these metazoans to assess trophic status or to characterize habitat variations of wetlands. The plankton samples collected from four beels of lower Assam revealed 160 Rotifera species belonging to 35 genera and 19 families. The richness is of biodiversity value as 38.0% and 57.0% of the rotifer species known till date from India and northeast India (NEI), respectively. One species each is new to the Oriental region and NEI, and three species are new to Assam; 23 species merit global biogeography interest and several exhibit distribution values in the Indian sub-region. The diverse Lecanidae > Brachionidae > Lepadellidae > Trichocercidae and speciose littoral-periphytic Lecane > Lepadella > Trichocerca, and richness of Brachionus spp. following removal of aquatic macrophytes are noteworthy. Overall rotifer composition showed homogeneity amongst beels while lower monthly richness and community similarities affirmed heterogeneity within individual beels. We propose L/B quotient based on Lecane: Brachionus species ratios to characterize habitat variations of the sampled wetlands. Sládeček's B/T quotient based on Brachionus: Trichocerca species ratios affirmed general' meso-trophic' status of diff erent beels. Our results provided little insight on the influence of individual abiotic factors but the canonical correspondence analyses asserted higher cumulative influence of ten abiotic parameters on Rotifera richness in each beel.

    2013-09-01

    More than 80% of the world's almonds are grown in California with several dozen almond cultivars available commercially. To facilitate promotion and sale, almond cultivars are categorized into marketing groups based on kernel shape and appearance. Several marketing groups are recognized, with the Nonpareil Marketing Group (NMG) demanding the highest prices. Placement of cultivars into the NMG is historical and no objective standards exist for deciding whether newly developed cultivars belong in the NMG. Principal component analyses (PCA) were used to identify nut and kernel characteristics best separating the 4 NMG cultivars (Nonpareil, Jeffries, Kapareil, and Milow) from a representative of the California Marketing Group (cultivar Carmel) and the Mission Marketing Group (cultivar Padre). In addition, discriminant analyses were used to determine cultivar misclassification rates between and within the marketing groups. All 19 evaluated carpological characters differed significantly among the 6 cultivars and during 2 harvest seasons. A clear distinction of NMG cultivars from representatives of the California and Mission Marketing Groups was evident from a PCA involving the 6 cultivars. Further, NMG kernels were successfully discriminated from kernels representing the California and Mission Marketing Groups with overall kernel misclassification of only 2% using 16 of the 19 evaluated characters. Pellicle luminosity was the most discriminating character, regardless of the character set used in analyses. Results provide an objective classification of NMG almond kernels, clearly distinguishing them from kernels of cultivars representing the California and Mission Marketing Groups.

    2013-03-15

    Diets high in fruit and vegetables are known to have significant health benefits. This is in part due to the presence of phytochemicals, which possess potential protective health benefits. This study focuses on the ability of strawberries to be bred for higher anthocyanin content. This is a major contributor to the characteristic colour and nutritional value of ripe strawberries, together with phenolic acids, ascorbic acid and total antioxidant capacity. Anthocyanins in five commercial strawberry cultivars and three breeding lines were assessed. This led to the discovery of one breeding line (BL 2006-221) as an exceptional source of anthocyanins (~1 g kg(-1) fresh weight), with approximately double the levels of current commercial cultivars. Temperature was shown to influence anthocyanin extraction, with 40 °C being the best extraction temperature using the accelerated solvent extraction (ASE) method. Hue angle and anthocyanin concentration showed a good correlation (r(2) = 0.69). The new breeding line BL 2006-221 has the potential to be used in the development of phytochemically rich strawberry cultivars. Using hue angle as a screening tool for total anthocyanin concentration and extraction of anthocyanins from strawberries by ASE at 40 °C would support such cultivar development. © 2012 Commonwealth of Australia.

    2011-11-01

    Three hydroxybenzoic acids: p-hydroxybenzoic acid, vanillic acid and syringic acid; six hydroxycinnamic acids: p-coumaric acid, ferulic acid and four ferulic acid derivatives and a flavonoid (apigenin) were identified and quantified in 34 accessions corresponding to 19 cultivars of wheat applying HPLC coupled to diode array detector. Considerable differences between the wheat cultivars were observed in the phenolic contents. Some cultivars (Colorado, Del País, Barbilla, Jallado, Raspinegro Canario and Plaganudo) could be selected according to the high levels of phenolic compounds. Ferulic acid was the major phenolic acid compound followed by syringic and p-hydroxybenzoic acids. The proportion of ferulic acid present as dimeric forms ranged from 4.2 to 8.6% across all of the wheat cultivars analyzed. Apigenin, p-hydroxybenzoic and syringic acids did not show significant correlations. Many correlations between the determined hydroxycinnamic acids were observed. The ferulic acid and all the ferulic acid derivatives showed highly significant correlations, suggesting that the concentrations of diferulic acids depend on the concentration of ferulic acid.

    PubMed

    Hara, Masakazu; Ito, Fumio; Asai, Tatsuo; Kuboi, Toru

    2009-09-01

    The radish (Raphanus sativus) is a root vegetable of the Brassicaceae family which shows amylolytic activity in the taproot. However, there is little information about differences in these amylolytic activities among radish cultivars. We analyzed the amylase activities and starch contents of 7 kinds of radish cultivars. The Koshin cultivar showed the highest amylase activity, with a level approximately 6 times higher than that of the Sobutori cultivar, which had the lowest. Cultivars with higher amylase activities showed higher starch contents. These results suggest that there are intraspecies variations in amylolytic activities in radishes, and positive correlations between amylase activity and starch content.

    A total of 33 carnation cultivars cultured in Korea were screened for resistance to the southern root-knot nematode, Meloidogyne incognita. Carnations were tested by either inoculating with 5,000 eggs or by transplanting into a mixture of bedding medium and soil infested with an average of 435 second-stage juveniles/300 cm(3) soil. Cultivars, Desio, Castelaro, Kappa, Rara, Izu Pink, Target, and Antalia were highly resistant to M. incognita. Twelve cultivars were moderately resistant, and the remaining 14 cultivars were susceptible. These results were similar to those obtained when the cultivars were subjected to field populations of the condition on a carnation farm.

    To solve the malpractice problem, the Florida Medical Association has attempted during the last decade to bring about tort reform through the legislative process, but early successes were declared unconstitutional or ignored by the courts. In 1984, the FMA organized a constitutional initiative campaign called REASON '84, and secured a record 630,000 signatures of registered Florida voters to place a constitutional amendment on the 1984 Florida General Election ballot. The Florida Supreme Court in October 1984 removed the Association's constitutional Amendment 9 from the ballot. Dr. Coleman, past president of the Florida Medical Association, wrote the following during his term as president about the malpractice problem and its grave implications.

    1992-09-07

    This paper reports that Florida Gas Transmission Corp. (FGT), Houston, appears to have taken the lead in competition to serve Florida's growing gas markets. Florida Power and Light (FPL), Miami, decided to reserve transportation capacity on FGT's proposed Phase III expansion rather than the Sun Coast pipeline proposed by United Gas Pipe Line Co. (UGPL), Houston, and Coastal Corp. unit ANR Pipeline Co., Detroit (OGJ, Aug. 31, p. 31). Withdrawal of FPL, Florida's largest electric utility, from Sun Coast left the proposed 560 mile, 400 MMcfd intrastate gas transmission pipeline with only one major prospective client, Florida Power Corp., St. Petersburg. That forces UGPL and ANR to dissolve the partnership.

  16. Sustainability of transgenic insecticidal cultivars: integrating pest genetics and ecology.

    PubMed

    Gould, F

    1998-01-01

    This review examines potential impacts of transgenic cultivars on insect population dynamics and evolution. Experience with classically bred, insecticidal cultivars has demonstrated that a solid understanding of both the target insect's ecology and the cultivar's performance under varied field conditions will be essential for predicting area-wide effects of transgenic cultivars on pest and natural enemy dynamics. This experience has also demonstrated the evolutionary capacity of pests for adaptive response to insecticidal traits in crops. Biochemical and genetic studies of insect adaptation to the Bacillus thuringiensis (Bt) toxins expressed by currently marketed transgenic cultivars indicate a high risk for rapid adaptation if these cultivars are misused. Theoretical and practical issues involved in implementing strategies to delay pest adaptation to insecticidal cultivars are reviewed. Emphasis is placed on examining the "high dose"/refuge strategy that has become the goal of industry and regulatory authorities.

    Human populace of Assam, India repeatedly exposed to high concentration of iron in groundwater results in adverse health effects like hemochromatosis, liver cirrhosis and siderosis. In the present study, human hair and nail analysis were carried out to establish a possible relationship between iron toxicity and its deposition among the residents. Nail and hair iron concentrations ranged from 28.2 to 1046μgg(-1) (n=114) and 26.5-838 (n=108)μgg(-1) levels, respectively, among all the study participants. The iron content of the groundwater (421-5340μgL(-1)) (n=64) used for drinking purposes was positively correlated with both nail (r=0.788, p<0.0001) and hair (r=0.709, p<0.0001) iron concentrations. Age- and sex-matched controls corresponding to each group were selected from population residing in other parts of the country where groundwater does not have excess iron. All the study groups included population drinking iron-contaminated water above the WHO/BIS limit (>300µgL(-1)) for 5 years (Group 1), for more than 5-10 years (Group 2) and for more than 10 years (Group 3). Results suggested that the participants consuming groundwater exceeding the WHO limit of iron had significantly more iron accumulation than those using groundwater containing ≤300μgL(-1) iron (p<0.01). There was statistically higher concentration of iron in the nail samples than the hair samples in all the study groups (p<0.01). There was a positive correlation in iron concentration and the residence time of the participants (p<0.01). Iron levels in the male participants were significantly higher than the female participants in the present study (p<0.01). The current findings are sufficiently compelling to warrant more extensive study of iron exposure through drinking water and adverse effects to the human in the areas where iron concentration is high.

    2017-03-01

    The state of Assam in north-east India gained popularity in Asia because of discovery of oil. Pollution due to petroleum and gas exploration is a serious problem in Assam. Oil and gas exploration by various agencies in Assam resulted in soil pollution due to hydrocarbons (HCs) and heavy metals (HMs). Bioremediation gained considerable significance in addressing petroleum hydrocarbon polluted sites in various parts of the world. In this investigation, we have observed 15 species of plants belonging to grass growing on the contaminated soils. Among 15 species of grasses, 10 species with high important value index (IVI) were found to be better adapted. The highest IVI is exhibited by Axonopus compressus (21.41), and this grass can be identified as key ecological tool in the rehabilitation of the degraded site. But no definite correlation between the IVI and the biomass of the various grass existed in the study sites. Chemical study of rhizosphere (RS) and non-rhizosphere (NRS) soil of these grasses revealed both aromatic and aliphatic compounds (M.W. 178-456). Four-ring pyrene was detected in NRS soil but not in RS soil. Microbiological study of RS and NRS soil showed high colony-forming unit (CFU) of HC-degrading microbes in RS compared to NRS. The increased microbial catabolism in RS soil established the fact that pyrene is transformed to aliphatic compounds. Metals in RS soil ranged from (in mg kg(-1)) 222.6 to 267.3 (Cr), 854 to 956 (Pb) and 180 to 247 (Ni), but despite the very high total metal concentration in RS and NRS soil, the CaCl2-extracted metals were relatively low in RS soil (1.04 for Cr, 0.56 for Pb, 0.35 for Ni). Plants with the highest uptake of metals were Leersia hexandra (36.43 mg Cr kg(-1)) and Kyllinga brevifolia (67.73 mg Pb kg(-1) and 40.24 mg Ni kg(-1)). These plant species could be potentially exploited for biomonitoring and bioremediation. Out of 15 plant species, 8 of them have high percentages of cellulose, crude fibres, lignin

    Firmness and toughness of fruit, peel and pulp of seven different mango cultivars were studied over a ripening period of ten days to investigate the effects of harvesting stages (early, mid and late) on fruit quality. Parameters were measured at equatorial region of fruits using TA-Hdi Texture Analyzer. The textural characteristics showed a rapid decline in their behaviour until mangoes got ripened and thereafter, the decline became almost constant indicating the completion of ripening. However, the rate of decline in textural properties was found to be cultivar specific. In general, the changes in textural attributes were found to be significantly influenced by ripening period and stage of harvesting, but firmness attributes (peel, fruit and pulp) of early harvested mangoes did not differ significantly from mid harvested mangoes, while peel, fruit and pulp firmness of late harvested mangoes were found to be significantly lower than early and mid harvested mangoes.

The bulbs of cultivar '74-x' had the highest phenolic content (total phenolic, flavonoids) and the strongest antioxidant capacity (DPPH, FRAP, and CUPRAC), followed by bulbs of cultivar 'Hanzhong purple'; the bulbs of cultivar 'Gailiang' had the lowest phenolic content and antioxidant capacity (FRAP, CUPRAC, MCA). The bolts of 'Hanzhong purple' also had higher phenolic content. Principal components analysis (PCA) separated the cultivars into 3 groups according to phenolic and flavonoid contents and strength of antioxidant activity. The first group had higher HRSC, FRAP, and flavonoid content; the second group had higher total phenolic content and MCA; some cultivars in the third group had higher HRSC and FRAP. All 8 test garlic bulb extracts successfully prevented Human Vascular Endothelial Cell death and significantly prevented reactive-oxygen species (ROS) formation in oxidative stress model, in which cultivar '74-x' had highest protection capability, following by cultivar 'Hanzhong purple', and the bulbs of cultivar 'No. 105 from Korea' had the lower protection capability against cell death and ROS formation.

    Florida has approximately 593 mi of shoreline fronting on the Atlantic Ocean and Straits of Florida and approximately 673 mi of shoreline fronting on the Gulf of Mexico with an additional 5,000 mi of bay and estuary shoreline. Of a statewide total of 818.9 mi of open coast sandy beaches, 337.2 mi or 41.2% of the beaches are identified as erosion problem areas. These erosion problem areas include those beaches with a moderate or low erosion rate, but with a narrow width fronting a highly developed area, and those restored beaches with an active maintenance nourishment program. Of these erosion problem areas, 217.8 mi or 26.6% of the statewide beach length are areas of critical erosion; that is, segments of the shoreline where substantial development or recreation interests are threatened by the erosion processes. On a shorewide basis, the Atlantic Ocean beaches of Florida typically have historical erosion rates of between 0 and {minus}3 ft per year, while the Gulf of Mexico beaches typically have historical erosion rates of between 0 and {minus}2 ft per year. Many of the problem areas have shoreline erosion rates in the magnitude of between {minus}3 and {minus}5 ft per year. The most extreme erosion rates are occurring along the southern portion of St. Joseph Peninsula at Cape San Bias where the annual shoreline recession exceeds {minus}20 ft. Erosion conditions in Florida are most apparent as a result of storm tides and storm wave activity. Extreme meteorological events inflict significant erosion conditions in all beach areas of the state. Historical shoreline changes are often the cumulative effect of a number of storm events and their cycles of poststorm recovery. Erosion and damage from recent storms as well as efforts to mitigate storm damage have heightened the erosion problems and incited a public response through coastal construction regulation and beach management planning.

    Coral disease is a major cause of reef decline in the Florida Keys. Bacterium has been defined as the most common pathogen (disease-causing organism). Although much is being done to catalog coral diseases, map their locations, determine the causes of disease, or measure the rates of coral demise, very little research has been directed toward actually preventing or eliminating the diseases affecting coral and coral reef decline.

    A detailed survey of Hoolock hoolock was carried out in the Inner-Line Reserve Forest and the adjoining areas of Cachar district of southern Assam, India, from July 2010 to December 2011. About 150 km2 of the area was covered. In direct sighting, groups and individuals were counted in 7 localities (39.7 km2). Only 3.96 km2 of the actual forest area were occupied by these gibbons. Nine family groups and a solitary subadult, 33 individuals in all, made up the total count. Of these, adult males and females comprised 54.5% of the population while the subadults, juveniles and infants comprised 27.3, 12.1 and 6.1%, respectively. Each family group's home range was 0.31-0.51 km2. Of the 7 localities, only 1 had more than 1 family group. Habitat destruction and diverse threats to the hoolock gibbon in this area are examined in this paper.

    Background There is a growing interest in the role of allelic variants of the APOA1 gene in relation to a number of disorders. We described two common polymorphisms of the APOA1 gene, G-75A and C+83T and investigated their potential influence on the serum apolipoprotein A-I (apo A-I) levels in the native population of Assam — a region that is ethnically distinct and from where no information is hitherto available. Methods Blood samples were collected from 150 healthy volunteers. Apo A-I levels were estimated by immunoturbidometry. Genotyping was done by a PCR-RFLP method that involved DNA extraction from whole blood, followed by polymerase chain reaction and digestion of the PCR product by MspI restriction enzyme, and analysis of fragment sizes in 12% polyacrylamide gel. Results The GG variant at G-75A locus and CC variant at C+83T locus were the most prevalent. GG/CC was the most common combination. Homozygous TT genotype was not detected in any of the subjects. The rare allele frequencies for the G-75A and C+83T sites were found to be 0.22 and 0.06 respectively, which significantly differed from those reported in some other populations in neighbouring regions. Serum apo A-I concentrations did not vary significantly across the detected genotypes. These findings were consistent in both sexes. Conclusion We described the distribution of the G-75A and C+83T polymorphisms of the APOA1 gene in the population of Assam for the first time. These polymorphisms were not found to directly influence apo A-I concentrations in this population either individually or synergistically. PMID:26702398

    Assam is the highest tea producing state in India. A large number of workers are engaged in various units of tea industry. There are few reports on the health status of the tea garden workers. The present cytogenetic biomonitoring study was undertaken to investigate the genotoxic effect associated with workers in tea industries in southern Assam. Smokeless tobacco chewing along with betel nut is very common practice among the workers. Workers also get exposed periodically to mixture of pesticides. Employing buccal micronucleus cytome assay, exfoliated buccal cells were analyzed in 90 female tea garden and compared to 90 age and sex matched non-chewer control as well as 70 chewers who are not tea garden workers. Statistically significant (p<0.001) increase in genotoxic and cell death parameters was observed in tea garden workers compared to both the control groups. The frequency of cell proliferation biomarkers was highest in the chewer controls whereas genotoxic and cell death parameters were highest in tea garden workers. Linear correlation analysis revealed strong positive correlation between the duration of occupation and the frequency of micronucleus (r=0.597; p<0.001) as well as cell death parameters (r=0.588; p<0.001). Amount of chewing also had significant positive correlation with micronucleus frequency (r=0.243 or 5.9%; p<0.05) and cell death parameters (r=0.217; p<0.05). A statistically significant decrease in total RBC count, haemoglobin content as well as acetylcholine esterase in the blood of exposed individuals was observed. The average BMI among the tea garden workers was relatively lower compared to the control group. Pesticide exposure and chewing areca nut along with smokeless tobacco use may be responsible for changes in cytome parameters in exfoliated buccal cells.

    Machine vision or image analysis is an important tool in the study of morphology of any materials. This technique has been used successfully to differentiate the eleven oats cultivars based on morphological characters. The geometry of seeds was measured through image analyzer and the variation was observed and recorded. From the recorded data, the cluster analysis was carried out and it revealed that the cultivars could be grouped into two main clusters based on similarity in the measured parameters. Cultivar Sabzar, UPO 212, OL 9 and OL 88 formed one main cluster. The another main cluster includes cv. Kent, OS 6, UPO 94, HFO 114, OS 7, HJ 8 and JHO 822 with many sub clusters. Among the cultivars HJ 8 and JHO 822 has more similarity in all measured parameters than other cultivars. Thus morphological characterization through seed image analysis was found useful to discriminate the cultivars.

    In Brazil, there are numerous blackberry cultivars under cultivation, however, only a few cultivars, such as the Guarani, are displayed/used for processing. In this context the aim of this work was to study the effects of different Brazilian blackberry cultivars (Guarani, Brazos, Comanche, Tupy, Cherokee, Caingangue, and Choctaw) on the physicochemical characteristics, texture profiles and the consumer acceptance of the resulting jelly to identify the potential use of these cultivars in the jelly industry. It is feasible to produce blackberry jellies with the Tupy, Comanche, Brazos, Guarani, and Choctaw cultivars because these jellies demonstrated good acceptability combined with good productivity. Consumers were shown to have a preference for a less adhesive, more acidic jelly. This study provides a useful insight about the Brazilian blackberry cultivar potential in jelly processing.

    Reproductive problems are becoming the most predominant health care problems in many countries. World Health Organization (WHO), in 2012, also exemplified maternal illnesses, for instance, birth asphyxia and post birth difficulties are rising at an alarming rate. In addition, not all abnormalities of the human reproductive system have the same origin; the effects of reproductive problems would likely been affected by both male and female. For easy accessibility and affordability, medicinal plants are playing crucial role in primary healthcare services in India and their use is moreover, an integral part of the cultural heritage. However, our growing understanding of the human reproductive problems are segregated and scanty for herbal medications. To document the local name of the medicinal plants used by both male and female from indigenous knowledge for the treatment of reproductive ailments and to explore their biological and pharmacological confirmation and to address the class of secondary metabolites present therein. The results stem in September 2015-April 2016 from an array of informations that were collected by direct interviews of the traditional medicinal practitioners in three villages, viz. Jaha, Niz-Bahjani and Madhupur of the southern Nalbari district, Assam. Both semi-structured and open-ended interview schedule was carried out with purposively selected individuals and focus group discussion (FGD) in the three selected sites for this study. Systematic analysis of fidelity level percentage (FL %), preference ranking percentage (PR %) and formulation scoring (FS) were calculated. Electronic databases such as Google, Google Scholar, and ScienceDirect were also been used to search existing pharmacological citations. Finally, qualitative chemical profiling were executed for the plants whose PR % scores ≥ 65. A total of 71 plant species belonging to 48 families and 64 genera are reported to be used for the treatment of several reproductive problems such

    Knowing yield potential and yield stability of sugarcane cultivars is of significance in guiding sugarcane breeding and rationalising regional distribution of sugarcane cultivars. In the present study, a heritability-adjusted genotype main effect plus genotype × environment (HA-GGE) biplot program was used to analyze the cane and sucrose yields of 44 newly released sugarcane cultivars at eight pilot test sites. The cane and sucrose yields of nine cultivars were higher than those of the control cultivar ROC22. From the perspective of cane yield, cultivars FN 40 and YZ 06–407 were well adapted to a wider range of conditions and produced relatively high cane yields in several pilot sites. From the perspective of sucrose yield, cultivars LC 03–1137, FN 38, FN 41, MT 01–77 and LC 05–136 were well adapted to a wide range of conditions and produced relatively high sucrose yields. Based on these results, three high yielding and widely adapted cultivars, namely, FN 39, LC 05–136, and YZ 05–51 were recommended for production in three major Chinese sugarcane planting areas. The results will provide a theoretical basis for recommending the effective use and rational regional distribution of sugarcane cultivars in China. PMID:26499905

    Shein, K. A.

    2009-12-01

    Southern Florida is home to the unique Everglades ecosystem that feeds into the Florida Bay. Heavy precipitation events, either over the Everglades or the Bay can introduce pollutants and excessive fresh water into the bay, while prolonged drought reduces water levels in the wetlands and can contribute to hypersalinity events in the bay. Systematic changes in precipitation frequency and intensity can result in long-term negative impacts to these southern Florida ecosystems. This paper examines the historical in situ record of precipitation over southern Florida, with special emphasis on evaluating the behavior of heavy precipitation events and periods of deficit.

  14. Belonolaimus longicaudatus: An Emerging Pathogen of Peanut in Florida

    Kutsuwa, Kanan; Dickson, D. W.; Brito, J. A.; Jeyaprakash, A.; Drew, A.

    2015-01-01

    Sting nematode (Belonolaimus longicaudatus) is an economically important ectoparasitic nematode that is highly pathogenic on a wide range of agricultural crops in sandy soils of the southeastern United States. Although this species is commonly found in Florida in hardwood forests and as a soilborne pathogen on turfgrasses and numerous agronomic and horticultural crops, it has not been reported infecting peanut. In the summers of 2012 and 2013, sting nematode was found infecting three different peanut cultivars being grown on two separate peanut farms in Levy County, FL. The damage consisted of large irregular patches of stunted, chlorotic plants at both farms. The root systems were severely abbreviated and there were numerous punctate-like isolated lesions observed on pegs and pods of infected plants. Sting nematodes were extracted from soil collected around the roots of diseased peanut over the course of the peanut season at both farm sites. Peanut yield from one of these nematode-infested sites was 64% less than that observed in areas free from sting nematodes. The morphological characters of the nematode populations in these fields were congruous with those of the original and other published descriptions of B. longicaudatus. Moreover, the molecular analyses based on the sequences of D2/D3 expansion fragments of 28S rRNA and internal transcribed spacer (ITS) rRNA genes from the nematodes further collaborates the identification of the sting nematode isolates as B. longicaudatus. The sequences were deposited in GenBank (accession no. KF963097, KF963098 for ITS, and KF96399, KF963100 for D2-D3). The results of the phylogenetic analysis using the sequences of these isolates from peanut compared with those of other isolates from Florida suggests that the sting nematode from both peanut farms are genetically close to B. longicaudatus populations occurring in the state. Peanut plants inoculated with both nematode isolates showed punctate-like isolated lesions on pods

  8. Reproduction of the Reniform Nematode on Thirty Soybean Cultivars

    PubMed Central

    Robbins, R. T.; Rakes, L.; Elkins, C. R.

    1994-01-01

    In greenhouse experiments conducted in 1991 and 1992, the 30 soybean (Glycine max) cultivars most commonly grown in Arkansas in 1990 were tested for resistance to the reniform nematode, Rotylenchulus reniformis. 'Forrest' was the most resistant cultivar, whereas 'Braxton' was the most susceptible to R. reniformis. Cultivars Coker 485, Centennial, Stonewall, and Sharkey did not differ from Forrest (P = 0.01). Cultivars Lee 74, Coker 6955, Waiters, Davis, Pioneer 9442, and Narow did not differ from Braxton (P = 0.01). Cultivar Lloyd had the second highest reproductive index (Pf/Pi) in 1992 and for the combined test, but was significantly different from Braxton in 1991. The remaining cultivars were inconsistent in their reproductive indices. Two cultivars, Leflore and Lloyd, exhibited large variation in Pf/Pi. This may be due to multiple resistance genes and (or) segregation for resistance among individual seedlings. Segregation is possible because these varieties were not selected or tested for reniform nematode resistance during the cultivar development process. PMID:19279944

    Breeding high-yielding rice cultivars through increasing biomass is a key strategy to meet rising global food demands. Yet, increasing rice growth can stimulate methane (CH4 ) emissions, exacerbating global climate change, as rice cultivation is a major source of this powerful greenhouse gas. Here, we show in a series of experiments that high-yielding rice cultivars actually reduce CH4 emissions from typical paddy soils. Averaged across 33 rice cultivars, a biomass increase of 10% resulted in a 10.3% decrease in CH4 emissions in a soil with a high carbon (C) content. Compared to a low-yielding cultivar, a high-yielding cultivar significantly increased root porosity and the abundance of methane-consuming microorganisms, suggesting that the larger and more porous root systems of high-yielding cultivars facilitated CH4 oxidation by promoting O2 transport to soils. Our results were further supported by a meta-analysis, showing that high-yielding rice cultivars strongly decrease CH4 emissions from paddy soils with high organic C contents. Based on our results, increasing rice biomass by 10% could reduce annual CH4 emissions from Chinese rice agriculture by 7.1%. Our findings suggest that modern rice breeding strategies for high-yielding cultivars can substantially mitigate paddy CH4 emission in China and other rice growing regions. © 2017 John Wiley & Sons Ltd.

Numerous outreach materials, including Frequently Asked Question (FAQ) cards, exhibits for local museums and aquaria, public beach signs, and numerous websites have been developed to disseminate information to the public about this natural hazard. In addition, during intense onshore blooms, a great deal of media attention, primarily via newspaper (print and web) and television, is focused on red tide. However to date, the only measure of effectiveness of these outreach methods has been counts of the number of people exposed to the information, e.g., visits to a website or number of FAQ cards distributed. No formal assessment has been conducted to determine if these materials meet their goal of informing the public about Florida red tide. Also, although local residents have the opinion that they are very knowledgeable about Florida red tide, this has not been verified empirically. This study addressed these issues by creating and administering an evaluation tool for the assessment of public knowledge about Florida red tide. A focus group of Florida red tide outreach developers assisted in the creation of the evaluation tool. The location of the evaluation was the west coast of Florida, in Sarasota County. The objective was to assess the knowledge of the general public about Florida red tide. This assessment identified gaps in public knowledge regarding Florida red tides and also identified what information sources people want to use to obtain information on Florida red tide.

    Background Green tea has various health promotion effects. Although there are numerous tea cultivars, little is known about the differences in their nutraceutical properties. Metabolic profiling techniques can provide information on the relationship between the metabolome and factors such as phenotype or quality. Here, we performed metabolomic analyses to explore the relationship between the metabolome and health-promoting attributes (bioactivity) of diverse Japanese green tea cultivars. Methodology/Principal Findings We investigated the ability of leaf extracts from 43 Japanese green tea cultivars to inhibit thrombin-induced phosphorylation of myosin regulatory light chain (MRLC) in human umbilical vein endothelial cells (HUVECs). This thrombin-induced phosphorylation is a potential hallmark of vascular endothelial dysfunction. Among the tested cultivars, Cha Chuukanbohon Nou-6 (Nou-6) and Sunrouge (SR) strongly inhibited MRLC phosphorylation. To evaluate the bioactivity of green tea cultivars using a metabolomics approach, the metabolite profiles of all tea extracts were determined by high-performance liquid chromatography-mass spectrometry (LC-MS). Multivariate statistical analyses, principal component analysis (PCA) and orthogonal partial least-squares-discriminant analysis (OPLS-DA), revealed differences among green tea cultivars with respect to their ability to inhibit MRLC phosphorylation. In the SR cultivar, polyphenols were associated with its unique metabolic profile and its bioactivity. In addition, using partial least-squares (PLS) regression analysis, we succeeded in constructing a reliable bioactivity-prediction model to predict the inhibitory effect of tea cultivars based on their metabolome. This model was based on certain identified metabolites that were associated with bioactivity. When added to an extract from the non-bioactive cultivar Yabukita, several metabolites enriched in SR were able to transform the extract into a bioactive extract

    Ground water is the principal source of drinking water in Assam. Ground water contamination of arsenic in drinking water is a great concern for human health and considered as a human carcinogen. The present cytogenetic biomonitoring study was undertaken to investigate the genotoxic effects associated with people of southern Assam consuming arsenic contaminated water and chewing tobacco. Employing the buccal cytome assay, exfoliated cells were analyzed in 138 individuals of age range 22-42 years and divided into four groups. Group I (n=54) are participants residing in localities where ground water contains arsenic concentration below the permissible limit (<10μg/l) and without any tobacco chewing history. Group II (n=32) participants from the same area but they are tobacco chewers. Group III (n=24) participants from localities where significantly high arsenic contamination in ground water were observed. Whereas the Group IV (n=28) consists of participants from the arsenic contaminated area and also tobacco chewers. Body mass index (BMI) in all the groups are found to be nearly same and in normal range. Statistically significant (P<0.001) increase in genotoxic, cell death parameters and cell proliferation biomarkers were observed in the Group IV compared to other groups. In the comet assay, percent of tail DNA gradually increases among the groups and has statistical significance. Spearman correlation revealed strong positive correlation between the arsenic exposed peoples and the binucleated cells (r=0.4763; P<0.001). Amount of chewing tobacco had significant positive correlation with micronucleus frequency (r=0.268; P<0.05) and karyolitic cells (r=0.217; P<0.05) and also in the percentage of tail DNA (r=0.5532, P<0.001). A statistically significant increase in glucose content and decrease in hemoglobin content as well as acetylcholine esterase in the blood of exposed individuals was observed.

    Lymphatic filariasis (LF) is endemic in the state of Assam and mass drug administration (MDA) programme for LF elimination is being implemented in the state since 2004. A study on prevalence of microfilaria (mf), disease endemicity and vector infection was carried out in a tea garden population of Dibrugarh, Assam (India) to assess the effect of ongoing MDA programme on elimination of LF. Finger prick thick blood smears (20 mm3) were made from individuals aged ≥2 yr old during night blood survey in between 2000-0000 hrs during the period of November 2012 to February 2013. Blood smears were dehaemoglobinised, stained with Giemsa and examined under microscope for presence of mf. Indoor resting mosquitoes were collected during 0600-1000 hrs and female Culex quinquefasciatus were dissected and examined under microscope for larval forms of the parasite. A total of 634 blood smears were collected and screened for mf and 47 (7.41%) individuals were found microfilaraemic, with predominance of males (74.5%). Highest mf rate (20.0%) was seen in the males of 30-39 yr age group while in females, age group of 10-19 yr recorded maximum mf rate (5.48%). Entomological collection and dissection of Cx. quinquefasciatus revealed presence of larval stages of the parasite and infection and infectivity rates recorded were 13.20 and 3.70%, respectively. Chronic clinical manifestations in the form of elephantiasis and hydrocele were recorded in 33 (5.73%) subjects of the 575 examined. Mass drug administration data showed six rounds of MDA with drug distribution coverage in between 63.42 and 95.93% in the study population. Out of 634 individuals examined 47 were found microfilaraemic giving an overall infection rate of 7.41%. Mosquito vector infection and infectivity rates were 13.20 and 3.70%, respectively. Presence of high mf rate, vector infectivity rate and clinical cases in the study population after six rounds of MDA warrants concerted efforts to be made for effective

    1984-01-01

    Mineral surveys of the Natural Area Roadless Area, Florida, identified a substantiated resource potential for scattered low-grade phosphate deposits. The area has little promise for the occurrence of other mineral resources or oil and gas, although the possibilities for the occurrence of these two hydrocarbons cannot be ruled out. The only mineral material that has been produced in the area is clayey sand used in stabilizing roads. Peaty material is present in swamps in the roadless area, but none of it is thick or pure and no resource potential was identified. Limestone underlies all of the Natural Area Roadless Area but is under too much overburden for quarrying. Heavy minerals are present in the area but are not sufficiently concentrated to consider the area as having resource potential.

    Lake County includes a 1,150 square-mile area consisting of ridges, uplands, and valleys in central-peninsular Florida. About 32 percent of the county is covered by lakes, swamps, and marshes. Water requirements in 1970 averaged about 54 million gallons per day. About 85 percent of the water was obtained from wells; about 15 percent from lakes. The Floridan aquifer supplies almost all the ground water used in Lake County. Annual recharge to the Floridan aquifer averages about 7 inches over the county; runoff average 8.5 inches. The quality of ground and surface water in Lake County is in general good enough for most uses; however, the poor quality of Floridan-aquifer water in the St. John River Valley probably results from the upward movement of saline water along a fault zone. Surface water in Lake County is usually less mineralized than ground water but is more turbid and colored. (Woodard-USGS)

    On the basis of a mineral survey the Clear Lake Roadless Area, Florida was concluded to offer little or no promise for the occurrence of mineral resources. The only commodity that has been mined in the area is clayey sand used in stabilizing roads and in highway construction. No peat more than a few inches thick occurs in the area. Limestone underlies all of the Clear Lake area but is under thick overburden. The region has been explored for heavy minerals and phosphate, but no resources have been found. There appears to be little promise for discovery of oil and gas in the Clear Lake area. However, the area and nearby lands have not been thoroughly tested for oil and gas, and the possibilities for discovery cannot be ruled out.

    The physicochemical (pH, texture, Vitamin C, ash, fat, minerals) and sensory properties of banana were correlated with the genotype and growing conditions. Minerals in particular were shown to discriminate banana cultivars of different geographical origin quite accurately. Another issue relates to the beneficial properties of bananas both in terms of the high dietary fiber and antioxidant compounds, the latter being abundant in the peel. Therefore, banana can be further exploited for extracting several important components such as starch, and antioxidant compounds which can find industrial and pharmaceutical applications. Finally, the various storage methodologies were presented with an emphasis on Modified Atmosphere Packaging which appears to be one of the most promising of technologies.

    2009-07-01

    This research integrates theoretical frameworks of risk perception, social amplification of risk, and the role of place-specific contexts in order to explore the various perceptions surrounding Florida red tides. Florida red tides are naturally occurring events that are increasing in frequency, duration, and severity. This has implications for public health, the local economy, and ecosystem health. While many of the negative impacts of Florida red tides are not easily controlled, some of the secondary impacts may be mitigated through individuals' responses. However, public perception and consequent reactions to Florida red tides have not been investigated. This research uses questionnaire surveys, and semi-structured interviews, to explore the various perceptions of the risk surrounding red tides. Surveys and interviews were conducted along two Florida west coast beaches. The results indicate that the underlying foundations of the social amplification of the risk framework are applicable to understanding how individuals form perceptions of risk relative to red tide events. There are key differences between the spatial locations of individuals and corresponding perceptions, indicating that place-specific contexts are essential to understanding how individuals receive and interpret risk information. The results also suggest that individuals may be lacking efficient and up-to-date information about Florida red tides and their impacts because of inconsistent public outreach. Overall, social and spatial factors appear to be influential as to whether individuals amplify or attenuate the risks associated with Florida red tides.

  10. Mysterious Black Water off Florida's Gulf Coast

    NASA Technical Reports Server (NTRS)

    2002-01-01

    In mid-December last year, a mysterious black water overtook the normally bluish green waters of Florida Bay. Over the course of the winter, the extent of the water grew to encompass an area as big as Lake Okeechobee, Florida, before subsiding over the last few weeks. These images taken by the Sea-viewing Wide Field-of-View Sensor (SeaWiFS), flying aboard the Orbview-2 satellite, show the progression of the black water over the last three months. The affected water sits along the southeastern coast of Florida about fifty miles north of the Florida Keys. As of now, scientists do not know why the water appears black in satellite and aerial images or whether the water is harming the wildlife. They speculate that it could be due to an exotic algae bloom, an underwater fountain pushing up sediments from the ocean floor, or possibly chemical and sediment run-off from the nearby Shark River. Researchers at the Florida Marine Research Institute in St. Petersburg and the Mote Marine Research Institute in Sarasota are running tests to determine the chemical make-up of the water. No big fish kills have been reported in the area. But fishermen say the catch has been low this winter. In addition, the black water sits just north of the Florida Keys National Marine Sanctuary, which is home to one of the largest coral reef habitats in the United States. Toxic run-off from the Florida coastline and motor boats in the area have already destroyed many of Florida's reefs. Scientists are concerned that if the extent of the black water grows again, it could endanger these reefs. Information provided by the Naples Daily News.

    There is a significant potential to improve the plant-beneficial effects of root-colonizing pseudomonads by breeding wheat genotypes with a greater capacity to sustain interactions with these bacteria. However, the interaction between pseudomonads and crop plants at the cultivar level, as well as the conditions which favor the accumulation of beneficial microorganisms in the wheat rhizosphere, is largely unknown. Therefore, we characterized the three Swiss winter wheat (Triticum aestivum) cultivars Arina, Zinal, and Cimetta for their ability to accumulate naturally occurring plant-beneficial pseudomonads in the rhizosphere. Cultivar performance was measured also by the ability to select for specific genotypes of 2,4-diacetylphloroglucinol (DAPG) producers in two different soils. Cultivar-specific differences were found; however, these were strongly influenced by the soil type. Denaturing gradient gel electrophoresis (DGGE) analysis of fragments of the DAPG biosynthetic gene phlD amplified from natural Pseudomonas rhizosphere populations revealed that phlD diversity substantially varied between the two soils and that there was a cultivar-specific accumulation of certain phlD genotypes in one soil but not in the other. Furthermore, the three cultivars were tested for their ability to benefit from Pseudomonas inoculants. Interestingly, Arina, which was best protected against Pythium ultimum infection by inoculation with Pseudomonas fluorescens biocontrol strain CHA0, was the cultivar which profited the least from the bacterial inoculant in terms of plant growth promotion in the absence of the pathogen. Knowledge gained of the interactions between wheat cultivars, beneficial pseudomonads, and soil types allows us to optimize cultivar-soil combinations for the promotion of growth through beneficial pseudomonads. Additionally, this information can be implemented by breeders into a new and unique breeding strategy for low-input and organic conditions.

    Tropical soils are particularly vulnerable to fertility losses due to their low capacity to retain organic matter and mineral nutrients. This urges the development of new agricultural practices to manage mineral nutrients and organic matter in a more sustainable way while relying less on fertilizer inputs. Two methods pertaining to ecological engineering and agroecology have been tested with some success: (1) the addition of biochar to the soil, and (2) the maintenance of higher earthworm densities. However, modern crop varieties have been selected to be adapted to agricultural practices and to the soil conditions they lead to and common cultivars might not be adapted to new practices. Using rice as a model plant, we compared the responsiveness to biochar and earthworms of five rice cultivars with contrasted selection histories. These cultivars had contrasted responsivenesses to earthworms, biochar, and the combination of both. The mean relative increase in grain biomass, among all treatments and cultivars, was 94% and 32%, respectively, with and without fertilization. Choosing the best combination of cultivar and treatment led to a more than fourfold increase in this mean benefit (a 437% and a 353% relative increase in grain biomass, respectively, with and without fertilization). Besides, the more rustic cultivar, a local landrace adapted to diverse and difficult conditions, responded the best to earthworms in terms of total biomass, while a modern common cultivar responded the best in term of grain biomass. This suggests that cultivars could be selected to amplify the benefit of biochar- and earthworm-based practices. Overall, selecting new cultivars interacting more closely with soil organisms and soil heterogeneity could increase agriculture sustainability, fostering the positive feedback loop between soils and plants that has evolved in natural ecosystems.

    The present study was undertaken to find out any correlation between serum zinc concentration and HbA1C% in patients with type 2 diabetes mellitus (DM). The study was carried out on 50 newly diagnosed patients of type 2 diabetes and controls in the Department of Biochemistry, Assam Medical College and Hospital, Dibrugarh. Analyses of blood glucose (fasting and postprandial), glycated hemoglobin (HbA1c), serum zinc, urea, and creatinine concentrations were performed by standard methods. Concentrations of fasting and postprandial blood glucose were significantly higher in the diabetic group than controls (P < 0.001) and the mean HbA1c% was also higher in cases (8.32% ±1.58%). The mean serum zinc concentration in cases was found to be significantly lower than controls (79.85 ± 13.4 vs. 109.74 ± 9.72 μg/dL) and P < 0.001 with correlation coefficient r = -0.804. Present study revealed an inverse relationship between HbA1C% and serum zinc concentration in patients with type 2 DM, substantiated by regression analysis.

    Introduction Health Management Information System (HMIS) is one of the important components of National Rural Health Mission (NRHM). The web portal of HMIS was launched by the Ministry of Health and Family Welfare (MOHFW), Govt. of India (GOI) in 21st Oct. 2008 to enable capturing of public health data from both public and private institutions in rural and urban areas across the country. Aim The aim of the study was to assess the quality perspectives and challenges among HMIS officials in implementing HMIS at their respective levels, i.e. district and block level. Materials and Methods We conducted a pilot qualitative study in two districts of Assam. HMIS officials working at district and block level were interviewed in-depth with the help of a semi-structured interview schedule which lasted from May to July 2014. Results Both HMIS and MCTS (Mother and Child Tracking System) formats were considered useful, by the HMIS officials, for data collection, planning at various levels, tracking maternal and neonatal deaths, institutional deliveries. HMIS officials reported that MCTS is useful for monitoring individual health status especially the status of the mother and child and HMIS being helpful as a health facility monitoring tool. Conclusion The study used a small sample size, hence similar type of studies are required with large sample size to understand the perspectives and challenges of HMIS officials in the implementation of HMIS.

    The aim of this study was to assess the regional impacts of heavy metals (Mn, Fe, Mg, Ca, Cu, Zn, Cd, Cr, Pb and Ni) on water, sediment and a native, teleost fish species, Labeo angra, inhabiting a flood plain wetland of Barak River in Assam, India. Heavy metal concentrations in the water, sediments and fish were measured; bioaccumulation factor, metal pollution index as well as condition indices were calculated, to assess the pollution load and health status of the fish. Multivariate statistical analysis was used on wetland water and sediment heavy metals to ascertain the possible sources and seasonal variations of the pollutants. Results showed that most heavy metals in the wetland water and sediments exceeded the water (drinking and irrigation) and sediment quality guidelines, respectively. Seasonal variations were observed for geogenic heavy metals, Mn, Fe, Mg and Ca while no seasonal variations were observed for anthropogenic heavy metals, Cu, Cd, Cr, Pb and Ni. Multivariate statistical analysis showed that there was strong correlation between geogenic and anthropogenic heavy metals in water and sediment, both originating from the common anthropogenic sources. Accumulation of most of the metals in all the tissues was above the safe limits as recommended by the Food and Agriculture Organization. High bioaccumulation factors and metal pollution index for these metals in the different tissues revealed that metals were extensively bio-accumulated and bioconcentrated. Condition indices in fish from the wetland suggested metabolic abnormalities.

    A new fossil leaf impression of Alphonsea Hk. f. & T. of the family Annonaceae is described from the Late Oligocene sediments of Makum Coalfield, Assam, India. This is the first authentic record of the fossil of Alphonsea from the Tertiary rocks of South Asia. The Late Oligocene was the time of the last significant globally warm climate and the fossil locality was at 10°-15°N palaeolatitude. The known palaeoflora and sedimentological studies indicate a fluvio-marine deltaic environment with a mosaic of mangrove, fluvial, mire and lacustrine depositional environments. During the depositional period the suturing between the Indian and Eurasian plates was not complete to facilitate the plant migration. The suturing was over by the end of the Late Oligocene/beginning of Early Miocene resulting in the migration of the genus to Southeast Asia where it is growing profusely at present. The present study is in congruence with the earlier published palaeofloral and molecular phylogenetic data. The study also suggests that the Indian plate was not only a biotic ferry during its northward voyage from Gondwana to Asia but also a place for the origin of several plant taxa.

    Solid-stemmed spring wheat cultivars (Triticum aestivum L.) are resistant to the stem sawfly (Cephus cinctus Nort.) and lodging. Anthers of 24 spring wheat cultivars with varying content of pith in the stem were used in the experiment. All were classified into three groups: solid, medium-solid and hollow stems. There was considerable influence of the cultivar on callus formation and green plant regeneration. The highest efficiency of green plant regeneration (24%) was observed for the solid-stemmed AC Abbey cultivar. There was no regeneration from the explants of four cultivars: CLTR 7027, Alentejano, Marquis and Bombona. Principal component analysis showed no differences between the cases under observation (callus induction and green plant regeneration) in their response to pre-treatment temperatures (4 and 8°C). The examination of the effects of various auxin types in the induction medium on callus formation and green plant regeneration revealed that the strongest stimulation of these processes was observed in the C17 medium with 2,4-D and dicamba. The efficiency of callus formation and green plant regeneration was greater in solid-stemmed cultivars than in hollow-stemmed cultivars.

    This study evaluated the degree of sediment contamination in several South Florida estuaries. During the 2010 National Condition Assessment, Florida Fish and Wildlife Research Institute collected water column, sediment and biotic data from estuaries across the entire state of Florida. Sediments were analyzed for arsenic, cadmium, chromium, lead, mercury, zinc and total polychlorinated biphenyls and were compared relative to empirically derived sediment quality guidelines. As a result of this data collection and assessment effort, it was determined that the degree of contamination with respect to sediment was low for all southern Florida estuaries assessed, except the Miami River which was determined to be considerably contaminated. However only one monitoring location was used to assess the Miami River, and as such should be viewed with caution. A low degree of contamination was determined for Biscayne Bay sediments, possibly indicating a recovery from its previously reported higher contaminant level.

    INTRODUCTION Lakes are among the most valued natural resources of central Florida. The landscape of central Florida is riddled with lakeswhen viewed from the air, it almost seems there is more water than land. Florida has more naturally formed lakes than other southeastern States, where many lakes are created by building dams across streams. The abundance of lakes on the Florida peninsula is a result of the geology and geologic history of the State. An estimated 7,800 lakes in Florida are greater than 1 acre in surface area. Of these, 35 percent are located in just four counties (fig. 1): Lake, Orange, Osceola, and Polk (Hughes, 1974b). Lakes add to the aesthetic and commercial value of the area and are used by many residents and visitors for fishing, boating, swimming, and other types of outdoor recreation. Lakes also are used for other purposes such as irrigation, flood control, water supply, and navigation. Residents and visitors commonly ask questions such as Whyare there so many lakes here?, Why is my lake drying up (or flooding)?, or Is my lake spring-fed? These questions indicate that the basic hydrology of lakes and the interaction of lakes with ground water and surface water are not well understood by the general population. Because of the importance of lakes to residents of central Florida and the many questions and misconceptions about lakes, this primer was prepared by the U.S. Geological Survey (USGS) in cooperation with the St. Johns River Water Management District and the South Florida Water Management District. The USGS has been collecting hydrologic data in central Florida since the 1920s, obtaining valuable information that has been used to better understand the hydrology of the water resources of central Florida, including lakes. In addition to data collection, as of 1994, the USGS had published 66 reports and maps on central Florida lakes (Garcia and Hoy, 1995). The main purpose of this primer is to describe the hydrology of lakes in central

    Local water managers usually rely on information produced at the State and regional scale to make water-resource management decisions. Current assessments of hydrologic and water-quality conditions in Polk County, Florida, commonly end at the boundaries of two water management districts (South Florida Water Management District and the Southwest Florida Water Management District), which makes it difficult for managers to determine conditions throughout the county. The last comprehensive water-resources assessment of Polk County was published almost 40 years ago. To address the need for current countywide information, the U.S. Geological Survey began a 3?-year study in 2002 to update information about hydrologic and water-quality conditions in Polk County and identify changes that have occurred. Ground-water use in Polk County has decreased substantially since 1965. In 1965, total ground-water withdrawals in the county were about 350 million gallons per day. In 2002, withdrawals totaled about 285 million gallons per day, of which nearly 95 percent was from the Floridan aquifer system. Water-conservation practices mainly related to the phosphate-mining industry as well as the decrease in the number of mines in operation in Polk County have reduced total water use by about 65 million gallons per day since 1965. Polk County is underlain by three principal hydrogeologic units. The uppermost water-bearing unit is the surficial aquifer system, which is unconfined and composed primarily of clastic deposits. The surficial aquifer system is underlain by the intermediate confining unit, which grades into the intermediate aquifer system and consists of up to two water-bearing zones composed of interbedded clastic and carbonate rocks. The lowermost hydrogeologic unit is the Floridan aquifer system. The Floridan aquifer system, a thick sequence of permeable limestone and dolostone, consists of the Upper Floridan aquifer, a middle semiconfining unit, a middle confining unit, and

  7. Jurassic hydrocarbon exploration of southern Florida

    Mitchell-Tapping, H.J.

    1994-09-01

    South Florida Jurassic exploration has been overlooked as a viable exploration target due to lack of data and plate-tectonics application. In Florida, {open_quotes}basement{close_quotes} is defined as crystalline, igneous, metamorphic, and unmetamorphosed sediments of Paleozoic age. Age-dating of zircons has proven that the Florida lower Paleozoic terrane is not akin to that of North America but is part of the West African Guinean shield. Previous published reconstructions of late Paleozoic fits of crustal plates and continents have failed to account for the differences in peninsula Florida basement and the geologic and tectonic continuities of peninsula Florida, Yucatan, Cuba, Hispaniola, and Bahamas. Pre-Atlantic reconstruction of the Gulf of Mexico in this study proposes that there was a Florida connection to Yucatan-Cuba-Africa during the Triassic. This reconstruction also shows that the Jurassic sediments that are well known in the northern Gulf Coast should have been deposited in similar depositional environments in southern Florida. Deep drilling on the Florida peninsula has confirmed this hypothesis. By using plate tectonic reconstruction based on the rising of the North Atlantic Ocean and evidence from petrology of basement samples from deep wells together with petrographic analyses of Jurassic sediments, a Smackover-equivalent exploration play can be developed. Petrographic and petrophysical analysis of these wells that have encountered Jurassic marine shales, anhydrite, dolomite, carbonate, and elastic sediments has determined that these sediments are from shallow-water subtidal, tidal, intertidal, and supratidal environments. Excellent gas shows, oil stain in the pores and high TOC values in the marine shales, indicate that large accumulations of hydrocarbon are present.

    1985-01-18

    Annual and interannual variations in the Florida Current, Caribbean and subtropical Atlantic are investigated with the use of historical sea level differences and wind field data. Observational and model evidence suggests that the seasonal transport cycle of the Florida Current is locally forced, either upstream in the Caribbean or downstream over topography. Although at seasonal and shorter periods sea level or bottom pressure fluctuations on the left side of the Florida Current contribute almost all of the variance of sea level difference across the Florida Straits and hence transport, this relation does not seem to apply at interannual time scales. Using results from the Subtropical Atlantic Climate Studies, it is estimated from historical sea level data that interannual transport fluctuations of the Florida Current are only of order 1 x 10/sup 6/ cubic meters per second. Interannual fluctuations in the 2- to 3-year period range in the Florida Straits seem to be correlated with sea level differences across the Caribbean and the subtropical Atlantic but not with Sverdrup transport fluctuations in the subtropical Atlantic. 26 references, 2 figures.

    This chapter discusses the geology and hydrogeology of the Florida Keys, and focuses on the islands formed of Pleistocene limestone. These islands, which are crossed when driving from Miami to Key West, are typically regarded as "the Florida Keys." The outstanding and fragile character of ecosystems on and around the Florida Keys has prompted State and Federal efforts to protect and preserve the remaining public portions of the region. The Florida Keys were largely ignored during the sixteenth, seventeenth, and eighteenth centuries, although the waters just offshore provided a major shipping thoroughfare to and from the New World. The Florida Keys are now recognized as one of the great recreational and environmental resources of the United States. The islands are outposts of a laid-back, tropical resort culture that has as its foundation warmth and clear water. A significant part of the attraction is fishing, diving, and boating around the area's coral reefs, which the islands protect. But the reefs were not always so highly valued. The Florida Keys that have protected the reefs for millennia, may now be the source of the agents that may accomplish what Agassiz thought was beyond man's power a century ago.

  11. Late quaternary sequence stratigraphy, South Florida margin

    SciTech Connect

    Locker, S.D.; Hine, A.C.

    1995-12-01

    Late Quaternary sea-level change and the Florida Current have combined to produce a progradational shelf-slope margin along the western portion of the south Florida Platform facing the Straits of Florida. Analysis of high resolution seismic reflection profiles suggest at least eight 5th order late Quaternary sequences downlap onto the Pourtales Terrace at 250 m water depth. Along most of the south Florida margin, this Late Quaternary section is very thin, and only where significant accumulations occur can the stratigraphic patterns produced by sea-level change be clearly observed. Recognition of systems tracts and their boundaries from high-resolution seismic data is important for prediction of sedimentary facies and stratigraphic development of margins. Many south Florida seismic boundaries can be fit to the Exxon sequence stratigraphy model. Others appear to reflect the added effect of bottom-current erosion that complicates the signal produced by sea-level change. Overall, the sea-level signal appears to dominate the stratigraphic record, especially from the 2-dimensional perspective of dip-oriented seismic profiles. However, the 3-dimensional geometry of deposits are strongly influenced by along slope accumulation patterns controlled by the Florida Current. This study provides new insight on the importance of both geostrophic boundary currents and sea-level change in controlling stratigraphic development of a carbonate platform margin. Similar anomalously thick slope deposits in ancient sequences may indicate similar controls on accumulation and could lend to predictions of related paleo-platform configurations.

    Research Objective To evaluate the design, development, and implementation of Florida's Medicaid provider service network (PSN) demonstration, and the implications of that demonstration for subsequent Medicaid Reform in Florida. Data Sources, Data Collection Organizational analyses were based on archival and enrollment data obtained from Florida's Medicaid program and the South Florida Community Care Network, as well as key informant interviews. Closely related fiscal analyses utilized Medicaid claims data from March 1999 through October 2001 extracted from the Florida Medicaid Management Information System. Study Design The organizational analyses reported here were based on a structured case study research design. Principal Findings Almost every aspect of the development of the new organizational form (PSN) took longer and was more difficult than anticipated. Prior organizational experience with insurance functions proved to be an asset. While fiscal analyses indicated that the program saved the state of Florida a significant amount of money, tracking the precise origin of the savings proved to be challenging. Conclusions By most standards, the PSN program was observed to meet its stated objectives. Based in part on this conclusion, the state chose to extend the use of PSNs within its 2006 Medicaid Reform initiative. PMID:18199192

    The chemical composition, physicochemical, functional and sensory properties of mucilages, extracted from seven Italian flax cultivars, were evaluated. All samples were composed of neutral and acidic sugars, with a low protein content. From the NMR data, a rhamnogalacturonan backbone could be inferred as a common structural feature for all the mucilages, with some variations depending on the cultivar. All the suspensions showed a poor stability, which was consistent with a low zeta potential absolute value. The viscosity seemed to be positively correlated with the neutral sugars and negatively with the amount of proteins. Functional properties were dependent on the cultivar. The sensory analysis showed that most mucilages are tasteless. All these outcomes could support the use of flaxseed mucilages for industrial applications. In particular, Solal and Festival cultivars could be useful as thickeners, due to their high viscosity, while Natural, Valoal and Kaolin as emulsifiers for their good surface-active properties.

    Organic solvent extracts from fresh twig bark of Japanese pear cultivars (Pyrus serotina) Shinko and Nijisseiki, and European pear cultivar (P. communis) Le Lectier were obtained by maceration with n-hexane and EtOAc, and analyzed in GC-EIMS experiments. In these two Japanese cultivars, the lupeol, betulin, epifriedelinol, friedelin and arbutin contents of Nijisseiki were higher than those of Shinko. In the case of the lupane-type triterpenes, lupeol and betulin, the lupeol content of Japanese pears Shinko and Nijisseiki was higher than that of European pear Le Lectier. The betulin content of Le Lectier was higher than those of Shinko and Nijisseiki. Friedelane-type triterpenes, epifriedelinol and friedelin, were not detected in twig bark of Le Lectier. Quantitative and qualitative differences in the constituents of these three pear cultivars were observed.

    Chemical content in peels of fruits belonging to cultivars of Clementine mandarin (Fino, Loretina and Marisol), Satsume mandarin (Owari), Navel orange (Navelate and Navelina) and Common orange (Valencia Late) groups have been analyzed. The influence of the variety on the content of bioactive constituents at the varietal level is discussed. Rind contents showed similar tendencies for the majority of compounds although Satsume group presented the highest amounts on the flavanone glycosides hesperidin and narirutin, as well as the highest amounts of the carotenoid and β-cryptoxanthin, comparing with the remaining varieties studied. Both mandarin and orange varieties studied showed similar tendencies concerning to other phenolic compounds and total ascorbic acid concentrations. Limonene was the most abundant peel essential oil in all cultivars studied, followed by myrcene. Calcium and potassium were the dominant macronutrients for each cultivar studied, although the proportion of the individual nutrients ranged among different cultivars.

    Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested in the greenhouse. P. zeae, P. brachyurus, P. coffeae and P. scribneri decreased or increased only slightly in most instances. C. xenoplax increased as much as 330-fold and reproduced on all cultivars tested. In a field experiment with six peach cultivars and moderate numbers of P. brachyurus, P. vulnus, C. xenoplax, and M. incognita, only M. incognita caused significant stunting in 30 months. This nematode increased only on root-knot susceptible cultivars, whereas the other nematodes followed the same patterns observed in the greenhouse. In a second field experiment, seedlings were stunted significantly by high numbers of C. xenoplax during an 18-month period. PMID:19319348

The measured factors were primarily influenced by cultivar, and seasonal variations had relatively minor effects. The late-ripening cultivars 'Velluto Blue' and 'Centra Blue' had the highest fruit yields, anthocyanin contents and estimated total anthocyanin harvestable from a given area. 'Blue Moon' and 'Sky Blue' had the largest fruit sizes. The early-ripening cultivars 'Blue Bayou', 'Blue Moon' and 'Sunset Blue' had the lowest anthocyanin contents. The yield, fruit size and total anthocyanin content results obtained from any single year were highly correlated with the average of the three years, which makes pursuing the evaluation for these traits from a single year and at an early stage of plant development a practical proposition.

    Barley has a low glycemic index (GI), but it is unknown whether its GI is affected by variation in carbohydrate composition in different cultivars and by food processing and food form. To examine the effect of these factors on GI, 9 barley cultivars varying in amylose and β-glucan content were studied in 3 experiments in separate groups of 10 healthy participants. In Expt. 1, 3 barley cultivars underwent 2 levels of processing: hull removal [whole-grain (WG)] and bran, germ, and crease removal [white pearled (WP)]. GI varied by cultivar (CDC Fibar vs. AC Parkhill, [mean ± SEM]: 26 ± 3 vs. 53 ± 4, respectively; P < 0.05) and pearling (WG vs. WP: 26 ± 4 vs. 35 ± 3, respectively; P < 0.05) with no cultivar × pearling interaction. In Expt. 2, the GI of 7 WG cultivars ranged from 21 ± 4 to 36 ± 8 (P = 0.09). In Expt. 3, WG and WP AC Parkhill and Celebrity cultivars were ground and made into wet pasta. The GI of AC Parkhill pasta (69 ± 3) was similar to that of Celebrity pasta (64 ± 4) but, unlike in Expt. 1, the GI of WP pasta (61 ± 3) was less than that of WG pasta (72 ± 4) (P < 0.05). Pooled data from Expts. 1 and 2 showed that GI was correlated with total fiber (r = -0.75, P = 0.002) but not with measures of starch characteristics. We conclude that the GI of barley is influenced by cultivar, processing, and food form but is not predicted by its content of amylose or other starch characteristics.

    Resistance to soybean rust (SBR), caused by Phakopsora pachyrhizi Syd. & Syd., has been identified in many soybean germplasm accessions and is conferred by either dominant or recessive genes that have been mapped to six independent loci (Rpp1 –Rpp6), but No U.S. cultivars are resistant to SBR. The cultivar DT 2000 (PI 635999) has resistance to P. pachyrhizi isolates and field populations from the United States as well as Vietnam. A F6:7 recombinant inbred line (RIL) population derived from Williams 82 × DT 2000 was used to identify genomic regions associated with resistance to SBR in the field in Ha Noi, Vietnam, and in Quincy, Florida, in 2008. Bulked segregant analysis (BSA) was conducted using the soybean single nucleotide polymorphism (SNP) USLP 1.0 panel along with simple sequence repeat (SSR) markers to detect regions of the genome associated with resistance. BSA identified four BARC_SNP markers near the Rpp3 locus on chromosome (Chr.) 6. Genetic analysis identified an additional genomic region around the Rpp4 locus on Chr. 18 that was significantly associated with variation in the area under disease progress curve (AUDPC) values and sporulation in Vietnam. Molecular markers tightly linked to the DT 2000 resistance alleles on Chrs. 6 and 18 will be useful for marker-assisted selection and backcrossing in order to pyramid these genes with other available SBR resistance genes to develop new varieties with enhanced and durable resistance to SBR.

    Soybean is one of the main sources of foreign exchange credits for Brazil in the agricultural sector. There is increasing interest in growing this leguminous crop, especially in the southern region of Minas Gerais, due to its importance as an alternative for crop rotation with maize. In this respect, the study of the adaptability of new cultivars to the region is indispensable so as to obtain high yields. Thus, the aim of this study was to evaluate the performance of 38 soybean cultivars for growing in the summer season in the municipality of Lavras, MG, Brazil, in the 2010/2011 and 2011/2012 crop years. The experiments were conducted in a randomized block design with 3 replications and the treatments consisted of 38 cultivars. At the time of harvest, the following assessments were made: grain yield (kg/ha), height of the lowest pod (cm), plant height (cm), and lodging. The data were subjected to individual and combined analysis of variance. The phenotypic mean values were clustered, adopting the Scott and Knott test. For simultaneous selection of multiple traits, the sum of rank index of Mulamba and Mock was adopted. The cultivar TMG 801 RR had the best yield performance; the cultivars Monsoy 8001, MGBR-46 (Conquista), and BRSMG 68 (Vencedora) also stood out. Considering simultaneous selection for grain yield, plant height, height of the lowest pod, and lodging, the cultivar TMG 801 RR is recommended for growing in the summer season in the southern region of Minas Gerais.

    Viroids are the smallest infectious agents, and their genomes consist of a short single strand of RNA that does not encode any protein. Chrysanthemum stunt viroid (CSVd), a member of the family Pospiviroidae, causes chrysanthemum stunt disease. Here, we report the genomic variations of CSVd to understand the sequence variability of CSVd in different chrysanthemum cultivars. We randomly sampled 36 different chrysanthemum cultivars and examined the infection of CSVd in each cultivar by reverse transcription polymerase chain reaction (RT-PCR). Eleven cultivars were infected by CSVd. Cloning followed by Sanger sequencing successfully identified a total of 271 CSVd genomes derived from 12 plants from 11 cultivars. They were further classified into 105 CSVd variants. Each single chrysanthemum plant had a different set of CSVd variants. Moreover, different single plants from the same cultivar had different sets of CSVd variants but identical consensus genome sequences. A phylogenetic tree using 12 consensus genome sequences revealed three groups of CSVd genomes, while six different groups were defined by the phylogenetic analysis using 105 variants. Based on the consensus CSVd genome, by combining all variant sequences, we identified 99 single-nucleotide variations (SNVs) as well as three nucleotide positions showing high mutation rates. Although 99 SNVs were identified, most CSVd genomes in this study were derived from variant 1, which is identical to known CSVd SK1 showing pathogenicity. PMID:28149699

    In the cut flower market, traditional breeding is still the best way to achieve new rose cultivars. The geographical delocalization of cultivar constitution (generally made in Europe and North America) and plant cultivation (large areas in Africa and South America) represents a limit point for crossing and selection. Rose breeders often need to overcome geographical distances, resulting in asynchrony in flowering among crossing parents, by storing and sending pollen. Hence, a key aspect in breeding programs is linked to pollen availability and conservation, jointly with the identification of parameters related to pollen fertility. In this study we present the results of three different trials. In the first, pollen diameter and pollen viability were chosen as fertility predictors of 10 Rosa hybrida commercial cultivars. In the second trial, aliquots of dried pollen grains of six R. hybrida cultivar were stored under two different temperatures (freezer at T = -20 °C and deep freezer at T = -80 °C) and after a wide range of conservation period, their viability was measured. In the third trial, the effective fertilization capacity of frozen pollen of 19 pollen donor cultivars was evaluated during 2015 crossing breeding plan, performing 44 hybridizations and correlating the number of seeds and the ratio seeds/crossing, obtained by each cultivar, with in vitro pollen germination ability.

    Green tea and black tea are manufactured using appropriate tea cultivars in China. However, the metabolite differences relating to the manufacturing suitability of tea cultivars are unclear. In the present study, we performed a non-targeted metabolomic analysis on 13 Chinese tea cultivars using ultra-high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry to investigate comprehensively the metabolite differences between cultivars suitable for manufacturing green tea (GT cultivars) and cultivars suitable for manufacturing both green tea and black tea (G&BT cultivars). Multivariate statistical analysis and cluster analysis divided the 13 cultivars into two groups, namely GT cultivars and G&BT cultivars, which correlated with their manufacturing suitability. The GT cultivars contained higher levels of flavonoid glycosides, whereas the G&BT cultivars contained higher levels of catechins, dimeric catechins, phenolic acids and alkaloids. Metabolic pathway analysis revealed that the flavonoid pathway inclined toward the synthesis of flavonoid glycosides in GT cultivars, whereas it inclined toward the synthesis of catechins and phenolic acids in G&BT cultivars. The results of the present study will be helpful for discriminating the manufacturing suitability of tea cultivars and investigating their breeding. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Two cultivars Buram-3-ho (susceptible) and CR-Hagwang (moderate resistant) of kimchi cabbage seedlings showed differential defense responses to anthracnose (Colletotrichum higginsianum), black spot (Alternaria brassicicola) and black rot (Xanthomonas campestris pv. campestris, Xcc) diseases in our previous study. Defense-related hormones salicylic acid (SA), jasmonic acid (JA) and ethylene led to different transcriptional regulation of pathogenesis-related (PR) gene expression in both cultivars. In this study, exogenous application of SA suppressed basal defenses to C. higginsianum in the 1st leaves of the susceptible cultivar and cultivar resistance of the 2nd leaves of the resistant cultivar. SA also enhanced susceptibility of the susceptible cultivar to A. brassicicola. By contrast, SA elevated disease resistance to Xcc in the resistant cultivar, but not in the susceptible cultivar. Methyl jasmonate (MJ) treatment did not affect the disease resistance to C. higginsianum and Xcc in either cultivar, but it compromised the disease resistance to A. brassicicola in the resistant cultivar. Treatment with 1-aminocyclopropane-1-carboxylic acid (ACC) ethylene precursor did not change resistance of the either cultivar to C. higginsianum and Xcc. Effect of ACC pretreatment on the resistance to A. brassicicola was not distinguished between susceptible and resistant cultivars, because cultivar resistance of the resistant cultivar was lost by prolonged moist dark conditions. Taken together, exogenously applied SA, JA and ethylene altered defense signaling crosstalk to three diseases of anthracnose, black spot and black rot in a cultivar-dependent manner. PMID:25289020

    Densities of plant-parasitic nematodes were compared on six crops grown for forage during the summer of 1991 at seven sites in north central Florida. The cropping treatments were 'Howard' soybean (Glycine max), 'Deltapine 105' soybean, velvetbean (Mucuna deeringiana), 'California Blackeye #5' cowpea (Vigna unguiculata), 'Pioneer 3098' tropical corn (Zea mays), and 'Asgrow Chaparral' sorghum (Sorghum bicolor). Highest final densities (Pf) of Meloidogyne incognita and Criconemella spp. were obtained following corn or sorghum at most sites. The lowest Pf of M. incognita occurred after velvetbean at all seven sites, but Pf after cowpea were equivalent to Pf after velvetbean at four of seven sites. Cultivar choice is critical in planning rotations to suppress M. incognita because results obtained here and elsewhere have shown great differences among sorghum and cowpea cultivars. The Pf of Pratylenchus spp. were lowest following velvetbean at four of seven sites. There were no differences in densities of Paratrichodorus minor among crops, but populations increased at a greater rate if initial density (Pi) was low. Multiplication rates (Pf/Pi) of most nematode species on most crops varied inversely with Pi. An accurate impression of nematode multiplication and host status could not be obtained unless a range of Pi was examined. PMID:19283048

    Magnetic, gravity, seismic, and deep drill hole data integrated with plate tectonic reconstructions substantiate the existence of a transform plate boundary across southern Florida during the Jurassic. On the basis of this integrated suite of data the pre-Cretaceous Florida-Bahamas region can be divided into the pre-Jurassic North American plate, Jurassic marginal rift basins, and a broad Jurassic transform zone including stranded blocks of pre-Mesozoic continental crust. Major tectonic units include the Suwannee basin in northern Florida containing Paleozoic sedimentary rocks, a central Florida basement complex of Paleozoic age crystalline rock, the west Florida platform composed of stranded blocks of continental crust, the south Georgia rift containing Triassic sedimentary rocks which overlie block-faulted Suwannee basin sedimentary rocks, the Late Triassic-Jurassic age Apalachicola rift basin, and the Jurassic age south Florida, Bahamas, and Blake Plateau marginal rift basins. The major tectonic units are bounded by basement hinge zones and fracture zones (FZ). The basement hinge zone represents the block-faulted edge of the North American plate, separating Paleozoic and older crustal rocks from Jurassic rifted crust beneath the marginal basins. Fracture zones separate Mesozoic marginal sedimentary basins and include the Blake Spur FZ, Jacksonville FZ, Bahamas FZ, and Cuba FZ, bounding the Blake Plateau, Bahamas, south Florida, and southeastern Gulf of Mexico basins. The Bahamas FZ is the most important of all these features because its northwest extension coincides with the Gulf basin marginal fault zone, forming the southern edge of the North American plate during the Jurassic. The limited space between the North American and the South American/African plates requires that the Jurassic transform zone, connecting the Central Atlantic and the Gulf of Mexico spreading systems, was located between the Bahamas and Cuba FZ's in the region of southern Florida.

    A greenhouse experiment was conducted to compare the plant-tissue accumulation of Cd and Zn by four cultivars of barley (Hordeum vulgare L.) grown on three soils amended with 20 and 100 t/ha dried Imhoff tank sludges. Results indicated that metal uptakes by four cultivars of barley (Barsoy, Briggs, Florida 103, and Larker) were not significantly different when they were grown on both sludge-treated and non-sludge-treated (control) soils. The Cd and Zn concentrations of the plant tissue from sludge-treated soils, however, were significantly influenced by the sludge application and the soil type. For four cultivars of barley grown on the Ramona sandy loam soil, the Cd content of grain averaged <0.04 (<0.04-0.03) ..mu..g/g at the control and increased to 0.38 (0.19-0.53) ..mu..g/g at the 100-t/ha sludge treatment. Under the same conditions, the average Zn concentrations of barley grain were 41, 67, and 92 ..mu..g/g for the control, 20-t/ha, and 100-t/ha treatments, respectively. Both soil texture and pH influenced Cd and Zn contents of barley. Crops grown on the Domino loam soil (fine, mixed, thermic Xerollic Calciorthid) accumulated the least amounts of Cd and Zn. At heavy sludge applications, higher levels of plant-tissue Cd and Zn were often found in barley grown on soils of coarser texture (Ramona sandy loam (fine, mixed, thermic Typic Haploxeralf) and Greenfield sandy loam (coarse, mixed, thermic Typic Haploxeralf)) and lower pH (Ramona sand loam, pH = 6.0).

    The concentrations of the polymethoxylated flavones (PMFs) in peels of selected citrus cultivars grown in Jamaica and Mexico were determined. The PMFs were extracted from sun-dried citrus peels with reagent-grade methanol. Analyses were carried out by reverse-phase HPLC and UV detection. The column used was a C(18) 5 microm (150 x 4.6 mm) Discovery column. Elution was in the gradient mode, using a ternary mobile phase. The results showed that all the citrus cultivars used contained at least three of the six major PMFs quantified. Ortanique peel contained the highest quantity of PMFs (34,393 +/- 272 ppm), followed by tangerine (28,389 +/- 343 ppm) and Mexican sweet orange (sample 1; 21,627 +/- 494 ppm). The major PMFs, i.e. sinensetin, nobiletin, tangeretin, heptamethoxyflavone, tetramethylscutellarein and hexamethyl-o-quercetagetin, present in the peels of 20 citrus cultivars, was quantified. The results were compared with those of Florida citrus peels. A large amount of citrus peels and byproducts are produced in the Caribbean which could provide a cheap and convenient source of PMFs.

    Ten sulphur volatiles were observed in two Florida tomato cultivars ('Tasti-Lee' and 'FL 47') harvested at three maturity stages (breaker, turning, and pink) using gas chromatography with a pulsed flame photometric detector (GC-PFPD). Eight PFPD peaks were identified using retention values from authentic sulphur standards and GC-MS characteristic masses. Seven were quantified using an internal standard combined with external calibration curves. Dimethyl sulphide, dimethyl disulphide, dimethyl trisulphide 2-propylthiazole and 2-s-butylthiazole were newly identified in fresh tomatoes. Principal component analysis of sulphur volatiles indicated that there were appreciable maturity stage differences clustered in separate quadrants. GC-olfactometry (GC-O) identified 50 aroma-active compounds in 'Tasti-Lee', with 10 reported as odorants in fresh tomatoes for the first time. Four sulphur volatiles exhibited aroma activity, including two of the newly-reported fresh tomato sulphur volatiles, 2-s-butylthiazole and dimethyl sulphide. GC-O aroma profiling indicated that the most intense aroma category was earthy-musty, followed by fruity-floral, green-grassy, sweet-candy and sweaty-stale-sulphurous. Copyright © 2014 Elsevier Ltd.

  2. West Florida shelf upwelling: Origins and pathways

    2016-08-01

    Often described as oligotrophic, the west Florida continental shelf supports abundant fisheries, experiences blooms of the harmful alga, Karenia brevis, and exhibits subsurface chlorophyll maxima evident in shipboard and glider surveys. Renewal of inorganic nutrients by the upwelling of deeper ocean water onto the shelf may account for this, but what are the origins and pathways by which such new water may broach the shelf break and advance toward the shoreline? We address these questions via numerical model simulations of pseudo-Lagrangian, isopycnic water parcel trajectories. Focus is on 2010, when the west Florida shelf was subjected to an anomalously protracted period of upwelling caused by Gulf of Mexico Loop Current interactions with the shelf slope. Origins and pathways are determined by integrating trajectories over successive 45 day intervals, beginning from different locations along the shelf break and at various locations and depths along the shelf slope. Waters upwelling across the shelf break are found to originate from relatively shallow depths along the shelf slope. Even for the anomalous 2010 year, much of this upwelling occurs from about 150 m and above, although waters may broach the shelf break from 300 m depth, particularly in the Florida Panhandle. Such interannual renewal of west Florida shelf waters appears to have profound effects on west Florida shelf ecology.

  3. Genealogy of wine grape cultivars: "Pinot" is related to "Syrah".

    2006-08-01

    Since the domestication of wild grapes ca 6000 years ago, numerous cultivars have been generated by spontaneous or deliberate crosses, and up to 10 000 are still in existence today. Just as in human paternity analysis, DNA typing can reveal unexpected parentage of grape cultivars. In this study, we have analysed 89 grape cultivars with 60 microsatellite markers in order to accurately calculate the identity-by-descent (IBD) and relatedness (r) coefficients among six putatively related cultivars from France ("Pinot", "Syrah" and "Dureza") and northern Italy ("Teroldego", "Lagrein" and "Marzemino"). Using a recently developed likelihood-based approach to analyse kinship in grapes, we provide the first evidence of a genetic link between grapes across the Alps: "Dureza" and "Teroldego" turn out to be full-siblings (FS). For the first time in grapevine genetics we were able to detect FS without knowing one of the parents and identify unexpected second-degree relatives. We reconstructed the most likely pedigree that revealed a third-degree relationship between the worldwide-cultivated "Pinot" from Burgundy and "Syrah" from the Rhone Valley. Our finding was totally unsuspected by classical ampelography and it challenges the commonly assumed independent origins of these grape cultivars. Our results and this new approach in grape genetics will (a) help grape breeders to avoid choosing closely related varieties for new crosses, (b) provide pedigrees of cultivars in order to detect inheritance of disease-resistance genes and (c) open the way for future discoveries of first- and second-degree relationships between grape cultivars in order to better understand viticultural migrations.

Cross sectional data on 1034 women belonging to the age group of 19 years and above were collected following internationally accepted standards. The fertility of mothers by BMI range was found to be highest (6.50 (mean) +/- 0.14 (SE) and range being 1-11) amongst underweight mothers. The one-way analysis of variance (ANOVA) test of BMI and fertility shows significant relation between different BMI groups withp < 0.01. Highest haemoglobin levels were recorded in the age group of < or = 23 years with a mean of 11.61 +/- 0.06 g/dl, the range being 9.8-13.9 g/dl. Whereas lowest levels of haemoglobin were found in the age groups of 44+ years having a mean value of 10.26 +/- 0.04 g/dl and a range of 9.2-11.8 g/dl. The ANOVA analysis for haemoglobin content and corresponding fertility rates show significant difference between different hemoglobin levels with their live births at p < 0.01. The summary of ANOVA analysis for haemoglobin and BMI range shows the significant difference between groups i.e., normal, overweight and underweight. The t-value and F-ratio is 118.61 and 14068.42, respectively, which is significant at 1% probability. The authors conclude a general trend in the study population of women with high fertility having poor nutritional status. These findings might be important in formulating responsive health policies in an underdeveloped region.

    The hereditary hemoglobin (Hb) disorders are the most commonly encountered single gene disorders in India. Data pertaining to the pattern of hemoglobinopathies and thalassemias is scarce in North East India, and hence it was considered worthwhile to study these disorders using a large series of patients referred to a clinical diagnostic laboratory. A total of 9000 patients referred for Hb variant analysis were studied to identify hemoglobinopathies and thalassemias in Upper Assam region of North East India. This study was performed by high performance liquid chromatography (HPLC) using BIORAD variant Hb typing system. Out of 9000 patients studied, abnormal Hb fractions were seen in 5320 patients. The HbE gene was detected in 4315 patients of which HbE trait was seen in 2294 followed by HbE disease in 1892. There were 114 HbE beta thalassemia patients and 15 double heterozygotes of HbE with HbS or HbD. Beta thalassemia trait was seen in 313 patients and beta thalassemia homozygous in 32. HbS gene was detected in 460 patients comprising of HbS trait in 189, HbS disease in 203, S beta thalassemia in 53 and double heterozygotes of SD and ES in 15. The rest comprised of HbD trait in 6, delta beta thalassemia in 33, hereditary persistence of fetal hemoglobin trait in 5 and J chain hemoglobinopathy in 8 patients. Evidence of alpha thalassemia though suspected, could not be confirmed. A high incidence of hemoglobinopathies and thalassemias and their combinations is unique for this part of the country.

    Three sweet potato cultivars (TNG57, TNG66, and TNG73), provided by the Taiwanese Agricultural Research Institute (TARI), were stored at either 15 °C or under ambient conditions (23.8 ~ 28.4 °C and 77.1 ~ 81.0 % of relative humidity). Sweet potato roots were randomly chosen from each replicate and evaluated for measurement of weight loss, sugar content analysis, and sprouting after 0, 14, 24, 48, 56, 70, 84, and 98 days of storage. Fresh sweet potato roots were baked at 200 °C for 60 min then samples were taken for sugar analysis. After 14 days of ambient condition storage, the sprouting percentages for TNG57, TNG66, and TNG73 were 100, 85, and 95 % respectively. When sweet potatoes were stored at 15 °C, the weight loss became less and no sweet potato root sprouted after 14 days of storage. Because manufacturers can store sweet potatoes at 15 °C for almost 2 month without other treatments, the supply capacity shortage in July and September can be reduced. The total sugar content slowly increased along with increasing the storage time. After baking, the total sugar content of sweet potatoes significantly increased due to the formation of maltose. Maltose became the major sugar of baked sweet potatoes. Raw sweet potatoes stored at 15 °C had higher total sugar contents after baking than those stored under ambient conditions. Raw sweet potatoes were recommended to be stored at 15 °C before baking.

    Changes in the biosynthesis of individual carotenoid pigments have been investigated during fruit ripening of five cultivars of red pepper (Capsicum annuum L.): Mana, Numex, Belrubi, Delfin, and Negral (a chlorophyll-retaining mutant when ripe). The study was carried out throughout the ripening process, and with special emphasis on the ripe stage, to discover possible differences between cultivars and to characterize these by their carotenoid pattern and content for selecting the best varieties for breeding programs. Ripening fruit of the five cultivars showed the typical and characteristic pattern of carotenoid biosynthesis for the Capsicum genus. In the five cultivars, lutein and neoxanthin, both characteristic chloroplast pigments, decreased in concentration with ripening and eventually disappeared. beta-Carotene, antheraxanthin, and violaxanthin increased in concentration, and other pigments were biosynthesized de novo: zeaxanthin, beta-cryptoxanthin, capsanthin, capsorubin, capsanthin-5,6-epoxide, and cucurbitaxanthin A. A pool of zeaxanthin stands out of the rest of pigment during ripening, which reveals the importance of this pigment as a branching point in the carotenoid biosynthesis in Capsicum. Quantitatively, Negral cultivar showed the highest increase in total carotenoid content (48. 39-fold), followed by Mana and Delfin with 38.03- and 36.8-fold, respectively, and by Belrubi and Numex with 28.03- and 23.48-fold, respectively. In all the red varieties, there was an inverse relationship between total carotenoid content and the red to yellow isochromic pigment fraction ratio (R/Y) and the capsanthin-to-zeaxanthin ratio (Caps/Zeax). This seems to be related to the carotenogenic capacity of the cultivar, and thus selection and breeding should not only seek a higher total carotenoid content but also attempt to increase these ratios. In the present study, the cultivar Mana had the highest total carotenoid content (13 208 mg/kg dwt), but the lowest R/Y (1

  8. Florida lineament: Key tectonic element of eastern Gulf of Mexico

    The origin of the Florida lineament, a major basement lineament that strikes northwest-southeast across the West Florida Shelf and southern Florida, is a key to the history of the Gulf of Mexico. Regional magnetic and gravity trends are truncated along the Florida lineament. New geologic data from recent wells on the West Florida Shelf and magnetic anomaly data indicate that pre-Mesozoic basement terranes on opposite sides of the Florida lineament were contiguous prior to Triassic-Jurassic volcanism and exhibit only minimal lateral offset across the Florida lineament at present. The lack of major lateral offset of pre-Mesozoic basement terranes across the Florida lineament and lithologic and geophysical data suggest that the lineament represents a Triassic-Jurassic extensional rift margin. The Florida lineament is interpreted to be the southeastward continuation of the well-documented peripheral fault system, which delineates the rifted continental margin of the northern Gulf basin. The continuation of the peripheral fault system along the Florida lineament suggests that the tectonostratigraphic terranes associated with the Mesozoic producing trends of the northern Gulf basin may extend southeastward along the Florida lineament. The interpretation of the Florida lineament as an extensional rift margin places significant constraints on any tectonic model of the Gulf of Mexico region. A tectonic interpretation consistent with the constraints suggests that the West Florida Shelf and southern Florida region formed as the result of Triassic-Jurassic extension around a pole of rotation in central Florida. The central Florida pole of rotation is intermediate to the poles of rotation counterclockwise of Yucatan out of the northern Gulf basin. This suggests that the region south of the Florida lineament underwent extension synchronous with the rotation of the Yucatan block.

    Florida's Everglades is a region of broad, slow-moving sheets of water flowing southward over low-lying areas from Lake Okeechobeeto the Gulf of Mexico. In places this remarkable 'river of grass' is 80 kilometers wide. These images from the Multi-angle Imaging SpectroRadiometer show the Everglades region on January 16, 2002. Each image covers an area measuring 191 kilometers x 205 kilometers. The data were captured during Terra orbit 11072.

    On the left is a natural color view acquired by MISR's nadir camera. A portion of Lake Okeechobee is visible at the top, to the right of image center. South of the lake, whose name derives from the Seminole word for 'big water,' an extensive region of farmland known as the Everglades Agricultural Area is recognizable by its many clustered squares. Over half of the sugar produced in United States is grown here. Urban areas along the east coast and in the northern part of the image extend to the boundaries of Big Cypress Swamp, situated north of Everglades National Park.

    The image on the right combines red-band data from the 46-degree backward, nadir and 46-degree forward-viewing camera angles to create a red, green, blue false-color composite. One of the interesting uses of the composite image is for detecting surface water. Wet surfaces appear blue in this rendition because sun glitter produces a greater signal at the forward camera's view angle. Wetlands visible in these images include a series of shallow impoundments called Water Conservation Areas which were built to speed water flow through the Everglades in times of drought. In parts of the Everglades, these levees and extensive systems such as the Miami and Tamiami Canals have altered the natural cycles of water flow. For example, the water volume of the Shark River Slough, a natural wetland which feeds Everglades National Park, is influenced by the Tamiami Canal. The unique and intrinsic value of the Everglades is now widely recognized, and efforts to restore

    Pecan (Carya illinoensis) has been introduced to East China for over one hundred years, but its planting is still only occurring at a small scale. The key limiting factor is its low yield. To enhance the yield pecan in East China, two pecan cultivars, Mahan and Western, were examined. Twenty traits describing phasic development, yield, nut quality, and cultural practice were investigated. We found that pecan cultivar Mahan gives a higher yield and nut quality than cultivar Western. We recommend interplanting of cultivar Pawnee to act as a pollinator tree. Appropriate cultivation practices that can be implemented to enhance fruit yield of cultivars Mahan and Western include soil-applied paclobutrazol (PBZ) at certain concentrations, pinching, and supplementary pollination. For example, the addition of 1.25 g/m(2) of PBZ inhibits pecan branch growth and stimulates short bearing branches, which promotes fruit yield. We found that soil-applied PBZ reached optimal performance 82 days after application. A pinching length of 40 cm resulted in a fruit yield increase. In addition, grafting and transplantation may promote male flowering, but delays female flowering. These cultural practices may provide insights that can be used to improve pecan cultivation in East China.

    Banana cultivars––Luvhele (MusaABB), Mabonde (MusaAAA), and Muomva-red (Musa balbisiana) ––were characterized for morphological, physicochemical, and antioxidant properties. All three cultivars varied significantly (P < 0.05) in their morphology, pH, titratable acidity and total soluble solids with no significant difference in their ash content. Individual cultivars showed variations in flour starch granule when observed using a scanning electron microscope. Characterization of cultivars for total polyphenols (TPs) and antioxidant activity upon pretreatment with ascorbic, citric, and lactic acid shows that the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay of samples varied significantly as Muomva-red cultivar (1.02 ± 0.01 mg GA/g) expressed the highest DPPH activity at lactic acid concentration of 20 g/L. Total polyphenol content was also highest for Muomva-red [1091.76 ± 122.81 mg GAE/100 g (d.w.)]. The high amount of TPs present in these cultivars make them suitable source of bio-nutrients with great medicinal and health functions. PMID:25987997

    Historically occurring throughout the southeastern United States, the Florida panther is now restricted to less than 5% of its historic range in one breeding population located in southern Florida. Using radio-telemetry data from 87 prime-aged (≥3 years old) adult panthers (35 males and 52 females) during the period 2004 through 2013 (28,720 radio-locations), we analyzed the characteristics of the occupied area and used those attributes in a random forest model to develop a predictive distribution map for resident breeding panthers in southern Florida. Using 10-fold cross validation, the model was 87.5 % accurate in predicting presence or absence of panthers in the 16,678 km2 study area. Analysis of variable importance indicated that the amount of forests and forest edge, hydrology, and human population density were the most important factors determining presence or absence of panthers. Sensitivity analysis showed that the presence of human populations, roads, and agriculture (other than pasture) had strong negative effects on the probability of panther presence. Forest cover and forest edge had strong positive effects. The median model-predicted probability of presence for panther home ranges was 0.81 (0.82 for females and 0.74 for males). The model identified 5579 km2 of suitable breeding habitat remaining in southern Florida; 1399 km2 (25%) of this habitat is in non-protected private ownership. Because there is less panther habitat remaining than previously thought, we recommend that all remaining breeding habitat in south Florida should be maintained, and the current panther range should be expanded into south-central Florida. This model should be useful for evaluating the impacts of future development projects, in prioritizing areas for panther conservation, and in evaluating the potential impacts of sea-level rise and changes in hydrology.

    Women, particularly pregnant women, are the most vulnerable population of the society and their health status is one of the major indicators of development. There were enough studies on pre pregnancy body mass index (IPBMI) and inadequate weight gain during pregnancy (IWGP) of women in other part of the world and India, but none in Assam. In Assam a large number of population are in the category of low socio-economic group, a group most vulnerable to under nutrition. Thus this study was framed with the said indicators to throw light on the factors affecting the health status of pregnant women to accordingly address the situation. A cross sectional study using multistage sampling design with probability proportional to size was made comprising of 461 pregnant women belonging to low socio-economic status. Responses regarding their socio-economic, socio-cultural, health, diet and environmental background were collected and coded. The study revealed that although IPBMI (34.06%) was slightly lower than the reported state, national and global percentage the revealed IWGP (82%) was an astounding figure. The blood samples analyzed showed a high degree of inadequacy in almost all micronutrients (iron 63.1%, calcium 49.5% and copper 39.9%) studied in our survey.

    Florida has the highest degree of endemicity for eastern equine encephalitis virus (EEEV) of any state in the United States and is the only state with year-round transmission of EEEV. To further understand the viral population dynamics in Florida, the genome sequence of six EEEV isolates from central Florida were determined. These data were used to identify the most polymorphic regions of the EEEV genome from viruses isolated in Florida. The sequence of these polymorphic regions was then determined for 18 additional Florida isolates collected in four geographically distinct regions over a 20-year period. Phylogenetic analyses of these data suggested a rough temporal association of the Florida isolates, but no clustering by region or by source of the isolate. Some clustering of northeastern isolates with Florida isolates was seen, providing support for the hypothesis that Florida serves as a reservoir for the periodic introduction of EEEV into the northeastern United States.
