Developing COSHH Essentials: dermal exposure, personal protective equipment and first aid.  

PubMed

The 'control banding' approach in COSHH Essentials combines the potential for harm with the potential for exposure by inhalation to band measures to control exposure at source, as generic strategies. These are simply adapted to specific tasks and circumstances to produce specific control advice. Where it is not possible or practical to use this control advice, the control bands can suggest adequate respiratory protective equipment using 'protection factors'. Proposals in the paper enable the user to identify the right level of respiratory protective equipment (RPE), and to begin selecting suitable RPE. Selection is made through a formatted questionnaire, enabling the user to give the right facts to the supplier. COSHH Essentials applies mainly to exposure by inhalation. However, skin exposure is very common and uptake via the skin can be an important contributor to body dose. This paper examines the factors concerning skin exposure, and the options for banding the potential for harm to the skin or via the skin. Proposals have then been made for dermal exposure control. Planning for emergencies is an important facet of risk control. Proposals are outlined to band chemical hazards for emergency planning according to a minimum of information, i.e. the danger symbol on a product label. PMID:14530184

SLOPE STABILITY EVALUATION AND EQUIPMENT SETBACK DISTANCES FOR BURIAL GROUND EXCAVATIONS  

SciTech Connect

After 1970 Transuranic (TRU) and suspect TRU waste was buried in the ground with the intention that at some later date the waste would be retrieved and processed into a configuration for long term storage. To retrieve this waste the soil must be removed (excavated). Sloping the bank of the excavation is the method used to keep the excavation from collapsing and to provide protection for workers retrieving the waste. The purpose of this paper is to document the minimum distance (setback) that equipment must stay from the edge of the excavation to maintain a stable slope. This evaluation examines the equipment setback distance by dividing the equipment into two categories, (1) equipment used for excavation and (2) equipment used for retrieval. The section on excavation equipment will also discuss techniques used for excavation including the process of benching. Calculations 122633-C-004, 'Slope Stability Analysis' (Attachment A), and 300013-C-001, 'Crane Stability Analysis' (Attachment B), have been prepared to support this evaluation. As shown in the calculations the soil has the following properties: Unit weight 110 pounds per cubic foot; and Friction Angle (natural angle of repose) 38{sup o} or 1.28 horizontal to 1 vertical. Setback distances are measured from the top edge of the slope to the wheels/tracks of the vehicles and heavy equipment being utilized. The computer program utilized in the calculation uses the center of the wheel or track load for the analysis and this difference is accounted for in this evaluation.

Stability of essential drugs during shipment to the tropics.  

PubMed Central

OBJECTIVE--To determine whether present methods of international transport of essential drugs by sea adversely affect their quality. DESIGN--Controlled longitudinal study of drug shipments sent by sea from Unicef in Copenhagen to Lagos; to Mombasa and by land to Kampala; and to Bangkok. 11 essential drugs were stored in four locations on board the ships. SETTING--Main shipping routes from Unicef, Copenhagen, to tropical countries. MAIN OUTCOME MEASURES--Temperature and relative humidity in the test packs during the journey. Amount of active ingredient in the drugs before and after shipment. RESULTS--Temperatures recorded within the test packs range from -3.5 degrees C to 42.4 degrees C and were 3-12 degrees C higher than the ambient temperature. Relative humidity within the packs ranged from 20% to 88%. Differences between the locations on board were negligible. Ergometrine injection, methylergometrine injection, and retinol capsules lost 1.5-5.8% of their activity. Ampoules of ergometrine showed a large variation in the amount of active ingredient after shipment, with three of 80 samples having concentrations 60% below those stated. Ampicillin, benzylpenicillin, phenoxymethylpenicillin, and tetracycline were not affected by transport. CONCLUSIONS--Drugs were exposed to a much higher temperature and humidity than is recommended by the manufacturer, especially in tropical harbours and during inland transport. Except for ergometrine and methylergometrine the transport would not affect clinical effectiveness.

DDB1 is essential for genomic stability in developing epidermis  

PubMed Central

The mammalian epidermis is maintained by proliferation and differentiation of epidermal progenitor cells in a stereotyped developmental program. Here we report that tissue-specific deletion of the UV-damaged DNA-binding protein 1 (DDB1) in mouse epidermis led to dramatic accumulation of c-Jun and p21Cip1, arrest of cell cycle at G2/M, selective apoptosis of proliferating cells, and as a result, a nearly complete loss of the epidermis and hair follicles. Deletion of the p53 tumor suppressor gene partially rescued the epithelial progenitor cells from death and allowed for the accumulation of aneuploid cells in the epidermis. Our results suggest that DDB1 plays an important role in development by controlling levels of cell cycle regulators and thereby maintaining genomic stability.

Methods for thermal stability enhancement of leaf essential oils and their main constituents from indigenous cinnamon (Cinnamomum osmophloeum).  

PubMed

The thermal stability of leaf essential oils from various Cinnamomum osmophloeum and their constituents was investigated for the first time. The results indicated that trans-cinnamaldehyde (Cin) content in eugenol-free essential oil from C. osmophloeum was affected by high temperatures. The retention of Cin (RC) decreased to 17.4% after the essential oil was incubated for 8 h at 100 °C. In contrast, essential oils containing eugenol showed greater thermal stability. Seven kinds of antioxidants were added to Cin to improve its thermal stability. Among them, eugenol endowed Cin with the best thermal stability. We also investigated the influence of various amounts of eugenol on the thermal stability of both essential oil and Cin. Both essential oil and Cin showed excellent thermal stability when 0.62 and 2.60% (v/v) eugenol were added. In short, the thermal stability of essential oil and Cin could be effectively improved by adding appropriate amounts of eugenol. PMID:23738884

DEVELOPMENT OF EQUIPMENT FOR THE RETRIEVAL & STABILIZATION & ENCAPSULATION OF RADIOACTIVE SLUDGE AT THE HANFORD SITE  

SciTech Connect

This poster presentation describes and illustrates some of the equipment and tools that Fluor Hanford and BNG America have developed and designed to remove, transport, stabilize and encapsulate radioactive sludge from the K Basins at the Hanford nuclear site in Washington State, U.S.A. K Basins were built in the early 1950s to temporarily store irradiated nuclear fuel prior to chemical processing to remove plutonium for nuclear weapons. The sludge is the result of corrosion of these fuel elements and its removal is the final stage before the basin water can be drained and the basins decommissioned. The sludge is hydrogen-generating because of its uranium metal content and account has to be taken also of its heat generating capacity and criticality potential as it is moved from one containment to another. The paper describes all stages of sludge treatment from the use of vacuum wands to suck up the sludge, through consolidating the sludge in temporary underwater containers, transporting it though flexible, temporary pipe systems, acceleration of the corrosion of uranium to reduce hydrogen generation, measuring the fissile content and finally encapsulation in a cement grout. Emphasis is placed on the use of existing, transportable and temporary equipment. This not only saves initial costs but it also reduces the total amount of equipment needed to be disposed of as radioactive waste at the end of the job. The processes, equipment and tools described potentially have a broad applicability to nuclear site decommissioning and cleanup worldwide.

Improving Efficiency with 3-D Imaging: Technology Essential in Removing Plutonium Processing Equipment from Plutonium Finishing Plant Gloveboxes  

SciTech Connect

The Plutonium Finishing Plant at Hanford, Washington began operations in 1949 to process plutonium and plutonium products. Its primary mission was to produce plutonium metal, fabricate weapons parts, and stabilize reactive materials. These operations, and subsequent activities, were performed in remote production lines, consisting primarily of hundreds of gloveboxes. Over the years these gloveboxes and processes have been continuously modified. The plant is currently inactive and Fluor Hanford has been tasked to clean out contaminated equipment and gloveboxes from the facility so it can be demolished in the near future. Approximately 100 gloveboxes at PFP have been cleaned out in the past four years and about 90 gloveboxes remain to be cleaned out. Because specific commitment dates for this work have been established with the State of Washington and other entities, it is important to adopt work practices that increase the safety and speed of this effort. The most recent work practice to be adopted by Fluor Hanford D&D workers is the use of 3-D models to improve the efficiency of cleaning out radioactive gloveboxes at the plant. The use of 3-D models has significantly improved the work planning process by providing workers with a clear image of glovebox construction and composition, which is then used to determine cleanout methods and work sequences. The 3-D visual products enhance safety by enabling workers to more easily identify hazards and implement controls. In addition, the ability to identify and target the removal of radiological materials early in the D&D process provides substantial dose reduction for the workers.

Crosslinking renders bacteriophage HK97 capsid maturation irreversible and effects an essential stabilization  

PubMed Central

In HK97 capsid maturation, structural change (‘expansion') is accompanied by formation of covalent crosslinks, connecting residue K169 in the ‘E-loop' of each subunit with N356 on another subunit. We show by complementation experiments with the K169Y mutant, which cannot crosslink, that crosslinking is an essential function. The precursor Prohead-II passes through three expansion intermediate (EI) states en route to the end state, Head-II. We investigated the effects of expansion and crosslinking on stability by differential scanning calorimetry of wild-type and K169Y capsids. After expansion, the denaturation temperature (Tp) of K169Y capsids is slightly reduced, indicating that their thermal stability is not enhanced, but crosslinking effects a major stabilization (?Tp, +11°C). EI-II is the earliest capsid to form crosslinks. Cryo-electron microscopy shows that for both wild-type and K169Y EI-II, most E-loops are in the ‘up' position, 30 Å from the nearest N356: thus, crosslinking in EI-II represents capture of mobile E-loops in ‘down' positions. At pH 4, most K169Y capsids remain as EI-II, whereas wild-type capsids proceed to EI-III, suggesting that crosslink formation drives maturation by a Brownian ratchet mechanism.

Influence of spike lavender (Lavandula latifolia Med.) essential oil in the quality, stability and composition of soybean oil during microwave heating.  

PubMed

Lipids oxidation is one of the main factors leading to quality losses in foods. Its prevention or delay could be obtained by the addition of antioxidants. In this sense the present work intend to monitor the protective effects of Lavandula latifolia essential oil during soybean oil microwave heating. To achieve the proposed goal quality parameters (free acidity, peroxide value, specific coefficients of extinction and ?K), fatty acids profile, tocopherols and tocotrienols composition, antioxidant activity and oxidative stability were evaluated in soybean oil with and without spike lavender essential oils (EO) submitted to different microwave heating exposure times (1, 3, 5, 10 and 15 min; 1000 Watt) with a standard domestic microwave equipment. Microwave heating induced severe quality and composition losses, mainly above 3 min of microwave heating, regardless the sample tested. However, spike lavender EO addition counteracts the oxidation comparatively to control oils, by presenting enhanced values in quality parameters. A higher protection in unsaturated fatty acids loss was also observed as well as a higher antioxidant activity and oxidative stability. The microwave heating effects were clearly different in the samples with essential oils addition, allowing discrimination from plain soybean oils by a principal component analysis, being also capable to discriminate the different heating times tested within each sample.

Essential role of Pin1 in regulation of TRF1 stability and telomere maintenance  

PubMed Central

Telomeres are essential for maintaining cellular proliferative capacity and their loss has been implicated in aging. A key regulator in telomere maintenance is the telomeric protein TRF1, which was also identified as Pin2 in a same screen for Pin1. Pin1 is a unique prolyl isomerase that regulates protein conformation and function after phosphorylation. However, little is known about the role of Pin1 in telomere regulation and the modulation of TRF1 by upstream signals. Here we identify TRF1 as a major conserved substrate for Pin1 during telomere maintenance and aging. Pin1 inhibition renders TRF1 resistant to protein degradation, enhances TRF1 binding on telomeres, and leads to gradual telomere loss in human cells and in mice. Pin1-deficient mice also display widespread premature aging phenotypes within just one generation similar to those in telomerase-deficient mice after 4–5 consecutive generations. Thus, Pin1 is an essential novel regulator of TRF1 stability, telomere maintenance and aging.

Hybrid nanomaterial for stabilizing the antibiofilm activity of Eugenia carryophyllata essential oil.  

PubMed

The aim of the present study was to demonstrate that Fe(3)O(4)/oleic acid core/shell nanostructures could be used as systems for stabilizing the Eugenia carryophyllata essential oil (EO) on catheter surface pellicles, in order to improve their resistance to fungal colonization. EO microwave assisted extraction was performed in a Neo-Clevenger (related) device and its chemical composition was settled by GC-MS analysis. Fe(3)O(4)/oleic acid-core/shell nanoparticles (NP) were obtained by a precipitation method under microwave condition. High resolution transmission electron microscopy (HR-TEM) was used as a primary characterization method. The NPs were processed to achieve a core/shell/EO coated-shell nanosystem further used for coating the inner surface of central venous catheter samples. The tested fungal strains have been recently isolated from different clinical specimens. The biofilm architecture was assessed by confocal laser scanning microscopy (CLSM). Our results claim the usage of hybrid nanomaterial (core/shell/coated-shell) for the stabilization of E. carryophyllata EO, which prevented or inhibited the fungal biofilm development on the functionalized catheter, highlighting the opportunity of using these nanosystems to obtain improved, anti-biofilm coatings for biomedical applications.

Histone Chaperone Asf1 Plays an Essential Role in Maintaining Genomic Stability in Fission Yeast  

PubMed Central

The histone H3-H4 chaperone Asf1 is involved in chromatin assembly (or disassembly), histone exchange, regulation of transcription, and chromatin silencing in several organisms. To investigate the essential functions of Asf1 in Schizosaccharomyces pombe, asf1-ts mutants were constructed by random mutagenesis using PCR. One mutant (asf1-33(ts)) was mated with mutants in 77 different kinase genes to identify synthetic lethal combinations. The asf1-33 mutant required the DNA damage checkpoint factors Chk1 and Rad3 for its survival at the restrictive temperature. Chk1, but not Cds1, was phosphorylated in the asf1-33 mutant at the restrictive temperature, indicating that the DNA damage checkpoint was activated in the asf1-33 mutant. DNA damage occured in the asf1-33 mutant, with degradation of the chromosomal DNA observed through pulse-field gel electrophoresis and the formation of Rad22 foci. Sensitivity to micrococcal nuclease in the asf1-33 mutant was increased compared to the asf1+ strain at the restrictive temperature, suggesting that asf1 mutations also caused a defect in overall chromatin structure. The Asf1-33 mutant protein was mislocalized and incapable of binding histones. Furthermore, histone H3 levels at the centromeric outer repeat region were decreased in the asf1-33 mutant and heterochromatin structure was impaired. Finally, sim3, which encodes a CenH3 histone chaperone, was identified as a strong suppressor of the asf1-33 mutant. Taken together, these results clearly indicate that Asf1 plays an essential role in maintaining genomic stability in S. pombe.

Human single-stranded DNA binding proteins are essential for maintaining genomic stability  

PubMed Central

The double-stranded conformation of cellular DNA is a central aspect of DNA stabilisation and protection. The helix preserves the genetic code against chemical and enzymatic degradation, metabolic activation, and formation of secondary structures. However, there are various instances where single-stranded DNA is exposed, such as during replication or transcription, in the synthesis of chromosome ends, and following DNA damage. In these instances, single-stranded DNA binding proteins are essential for the sequestration and processing of single-stranded DNA. In order to bind single-stranded DNA, these proteins utilise a characteristic and evolutionary conserved single-stranded DNA-binding domain, the oligonucleotide/oligosaccharide-binding (OB)-fold. In the current review we discuss a subset of these proteins involved in the direct maintenance of genomic stability, an important cellular process in the conservation of cellular viability and prevention of malignant transformation. We discuss the central roles of single-stranded DNA binding proteins from the OB-fold domain family in DNA replication, the restart of stalled replication forks, DNA damage repair, cell cycle-checkpoint activation, and telomere maintenance.

Stabilization of emulsion and butter like products containing essential fatty acids using kalonji seeds extract and curcuminoids.  

PubMed

Owing to the tendency of essential fatty acids (EFAs) to undergo autoxidation, their storage becomes a key problem. Generally, they are stabilized by synthetic antioxidants like TBHQ that are toxic in nature. Recently many studies were reported where these EFAs are stabilized by natural antioxidants. In the present study, curcuminoids and kalonji seeds ethanol extract (KEE) were used to stabilize these EFAs in refined sunflower oil (RSFO), water-in-oil (w/o) emulsion and butter like products (BLPs). In RSFO, though curcuminoids alone exerted pro-oxidant effect, KEE and curcuminoids showed synergistic antioxidant activity that was comparable to TBHQ. KEE exhibited good antioxidant activity in emulsions and BLPs, providing fine physical properties like slipping point, dropping point and spreadability. EFAs increased the nutritional value of BLPs and antioxidants added for their stabilization provided their medicinal benefits. PMID:22188801

Effects of dietary oregano essential oil and vitamin E on the lipid oxidation stability of cooked chicken breast meat.  

PubMed

The antioxidant effect of oregano essential oil and vitamin E was evaluated in cooked chicken breast meat. In total, 480 broilers were randomly assigned to 6 treatments and 4 replications. Broilers were raised with a corn-soybean meal diet including either crude soybean oil or acidulated soybean oil soapstock, each supplemented with vitamin E at 10 or 100 mg or oregano essential oil at 100 mg/kg of feed. At 42 d, broilers were slaughtered and their breast meat was prepared into strips (1.5 × 10 cm) or patties (150 g). Fatty acid composition of the muscle was determined. For lipid oxidation stability, both meat strips and patties were cooked to an internal temperature of 74°C and malonaldehyde contents were assessed during 0, 3, 6, and 9 d of storage at 4°C. Each storage day had 4 replications per treatment. The meat lipid oxidative stability was estimated by content of malonaldehyde values. Results showed that feed consumption, weight gain, and feed conversion were not affected by the dietary oils or antioxidants, except for the mortality in acidulated soybean oil soapstock with the 10-mg vitamin E treatment. The fatty acid composition of the meat was similar between the 2 diets given the same antioxidant supplement. The oxidation stability of meat lipids in both types of meats showed a significant (P < 0.05) interaction between oils, antioxidants, and storage time. In the crude soybean oil oil diet, the malonaldehyde value in the 10-mg vitamin E treatment was the highest, followed by oregano essential oil, and then the 100-mg vitamin E treatment at 9 d of storage, whereas the value of oregano essential oil in the acidulated soybean oil soapstock diet was the highest, followed by the 10-mg vitamin E, and then the 100-mg vitamin E treatment during the 9 d of storage. In conclusion, the dietary oils and antioxidants used can be included in broiler diets without negative effects on their productivity. The antioxidant effect of vitamin E was higher with a higher supplementation level, regardless of the oil treatment, whereas the antioxidant effect of oregano essential oil was better in crude soybean oil than in the acidulated soybean oil soapstock diet.

Replication Fork Stability Is Essential for the Maintenance of Centromere Integrity in the Absence of Heterochromatin  

PubMed Central

Summary The centromere of many eukaryotes contains highly repetitive sequences marked by methylation of histone H3K9 by Clr4KMT1. This recruits multiple heterochromatin proteins including Swi6 and Chp1 to form a rigid centromere and ensure accurate chromosome segregation. In the absence of heterochromatin, cells show increased rate of recombination in the centromere, and chromosome loss. These defects are severely aggravated by loss of replication fork stability. Thus, heterochromatin proteins and replication fork protection mechanisms work in concert to prevent abnormal recombination, preserve centromere integrity, and ensure faithful chromosome segregation.

Lis1 is essential for cortical microtubule organization and desmosome stability in the epidermis  

PubMed Central

Desmosomes are cell–cell adhesion structures that integrate cytoskeletal networks. In addition to binding intermediate filaments, the desmosomal protein desmoplakin (DP) regulates microtubule reorganization in the epidermis. In this paper, we identify a specific subset of centrosomal proteins that are recruited to the cell cortex by DP upon epidermal differentiation. These include Lis1 and Ndel1, which are centrosomal proteins that regulate microtubule organization and anchoring in other cell types. This recruitment was mediated by a region of DP specific to a single isoform, DPI. Furthermore, we demonstrate that the epidermal-specific loss of Lis1 results in dramatic defects in microtubule reorganization. Lis1 ablation also causes desmosomal defects, characterized by decreased levels of desmosomal components, decreased attachment of keratin filaments, and increased turnover of desmosomal proteins at the cell cortex. This contributes to loss of epidermal barrier activity, resulting in completely penetrant perinatal lethality. This work reveals essential desmosome-associated components that control cortical microtubule organization and unexpected roles for centrosomal proteins in epidermal function.

O-GlcNAcase is essential for embryonic development and maintenance of genomic stability.  

PubMed

Dysregulation of O-GlcNAc modification catalyzed by O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA) contributes to the etiology of chronic diseases of aging, including cancer, cardiovascular disease, type 2 diabetes, and Alzheimer's disease. Here we found that natural aging in wild-type mice was marked by a decrease in OGA and OGT protein levels and an increase in O-GlcNAcylation in various tissues. Genetic disruption of OGA resulted in constitutively elevated O-GlcNAcylation in embryos and led to neonatal lethality with developmental delay. Importantly, we observed that serum-stimulated cell cycle entry induced increased O-GlcNAcylation and decreased its level after release from G2/M arrest, indicating that O-GlcNAc cycling by OGT and OGA is required for precise cell cycle control. Constitutively, elevated O-GlcNAcylation by OGA disruption impaired cell proliferation and resulted in mitotic defects with downregulation of mitotic regulators. OGA loss led to mitotic defects including cytokinesis failure and binucleation, increased lagging chromosomes, and micronuclei formation. These findings suggest an important role for O-GlcNAc cycling by OGA in embryonic development and the regulation of the maintenance of genomic stability linked to the aging process. PMID:22314054

Essential Roles of BCCIP in Mouse Embryonic Development and Structural Stability of Chromosomes  

PubMed Central

BCCIP is a BRCA2- and CDKN1A(p21)-interacting protein that has been implicated in the maintenance of genomic integrity. To understand the in vivo functions of BCCIP, we generated a conditional BCCIP knockdown transgenic mouse model using Cre-LoxP mediated RNA interference. The BCCIP knockdown embryos displayed impaired cellular proliferation and apoptosis at day E7.5. Consistent with these results, the in vitro proliferation of blastocysts and mouse embryonic fibroblasts (MEFs) of BCCIP knockdown mice were impaired considerably. The BCCIP deficient mouse embryos die before E11.5 day. Deletion of the p53 gene could not rescue the embryonic lethality due to BCCIP deficiency, but partially rescues the growth delay of mouse embryonic fibroblasts in vitro. To further understand the cause of development and proliferation defects in BCCIP-deficient mice, MEFs were subjected to chromosome stability analysis. The BCCIP-deficient MEFs displayed significant spontaneous chromosome structural alterations associated with replication stress, including a 3.5-fold induction of chromatid breaks. Remarkably, the BCCIP-deficient MEFs had a ?20-fold increase in sister chromatid union (SCU), yet the induction of sister chromatid exchanges (SCE) was modestly at 1.5 fold. SCU is a unique type of chromatid aberration that may give rise to chromatin bridges between daughter nuclei in anaphase. In addition, the BCCIP-deficient MEFs have reduced repair of irradiation-induced DNA damage and reductions of Rad51 protein and nuclear foci. Our data suggest a unique function of BCCIP, not only in repair of DNA damage, but also in resolving stalled replication forks and prevention of replication stress. In addition, BCCIP deficiency causes excessive spontaneous chromatin bridges via the formation of SCU, which can subsequently impair chromosome segregations in mitosis and cell division.

KIFC1 is essential for bipolar spindle formation and genomic stability in the primary human fibroblast IMR-90 cell.  

PubMed

Kinesin family member C1 (KIFC1) is the only member of the minus-end-directed kinesin-14 family in human cells. In cancer cells, KIFC1 plays an essential role in bipolar spindle formation by clustering the multiple poles during mitosis. However, it has not been clearly demonstrated whether KIFC1 also functions to mediate bipolar spindle formation and to maintain genomic stability in normal cells. In this study, by using human primary lung fibroblast IMR-90 cells, we showed that KIFC1 knock-down with lentiviral KIFC1 shRNA induced 17% of cells with multiple microtubule organizing centers (MTOCs) and delayed cyclin A degradation for more than 2 hr in early mitosis. However, these cells eventually carried out mitosis, resulting in 24% of cells with lagging chromosomes and 9% of cells with micronuclei after mitosis. Karyotyping of KIFC1-depleted IMR-90 cells demonstrated that cells with various abnormal numbers of chromosomes are produced. When IMR-90 cells treated with KIFC1 or the control shRNA for 60 hr were compared, 20% less cells were observed in KIFC1-depleted cells without an obvious immediate cell death. As reported for Mad2 depletion in IMR-90 cells, KIFC1-depleted IMR-90 cells showed typical features of senescence, like senescence-associated (SA) ?-galactosidase expression, when incubated 6 days or more. However, IMR-90 cells knocked down with both KIFC1 and Mad2 underwent apoptosis, suggesting that KIFC1 and Mad2 likely function in different pathways during mitosis. Taken together, we suggest that KIFC1 plays an essential role for bipolar MTOC formation and maintaining chromosomal stability in the mitosis of human primary fibroblast IMR-90. PMID:23318213

Essential Developmental, Genomic Stability, and Tumour Suppressor Functions of the Mouse Orthologue of hSSB1/NABP2  

PubMed Central

Single-stranded DNA binding proteins (SSBs) regulate multiple DNA transactions, including replication, transcription, and repair. We recently identified SSB1 as a novel protein critical for the initiation of ATM signaling and DNA double-strand break repair by homologous recombination. Here we report that germline Ssb1?/? embryos die at birth from respiratory failure due to severe rib cage malformation and impaired alveolar development, coupled with additional skeletal defects. Unexpectedly, Ssb1?/? fibroblasts did not exhibit defects in Atm signaling or ?-H2ax focus kinetics in response to ionizing radiation (IR), and B-cell specific deletion of Ssb1 did not affect class-switch recombination in vitro. However, conditional deletion of Ssb1 in adult mice led to increased cancer susceptibility with broad tumour spectrum, impaired male fertility with testicular degeneration, and increased radiosensitivity and IR–induced chromosome breaks in vivo. Collectively, these results demonstrate essential roles of Ssb1 in embryogenesis, spermatogenesis, and genome stability in vivo.

Preferential solubilization behaviours and stability of some phenolic-bearing essential oils formulated in different microemulsion systems.  

PubMed

The solubilization behaviour of a number of essential oils (EOs) containing volatile phenolic constituents was investigated in five different micellar solutions. These oils include clove bud (Eugenia caryophyllata), thyme (Thymus serpyllum) and oregano (Thymus capitatus). Ternary and pseudo-ternary phase diagrams were constructed to assess the ability for microemulsion formation and dilutability of each system using non-ionic surfactants. Results showed that Tween 20 (T20) was more suitable to solubilize these oils compared with Tween 80 (T80). Clove EO was found to be easily microemulsifiable compared with the other EOs, whereas oregano showed the least tendency to form a microemulsion. Particle sizes measured at different dilution lines ranged between 5.9 and 16.9 nm. The chemical composition of each EO was revealed by gas chromatography and was correlated with the observed solubilization behaviour. The presence of solubilization enhancers like poly-ols and short-chain alcohols improved solubilization of all EOs; however, establishment of new dilution lines was controlled by EO type. Physical stability assessment showed that all microemulsions were stable against alternate freeze/thaw cycles which extended for 1 week. On the contrary, each system showed different temperature sensitivity in the thermal stress assessment. The results of this investigation can be useful in fabrication of thermodynamically stable aqueous system carrying aromatic and bioactive phenolics for different applications in personal hygiene, cosmetic, fragrance and pharmaceutical products.

Small cis-Acting Sequences That Specify Secondary Structures in a Chloroplast mRNA Are Essential for RNA Stability and Translation  

PubMed Central

Nucleus-encoded proteins interact with cis-acting elements in chloroplast transcripts to promote RNA stability and translation. We have analyzed the structure and function of three such elements within the Chlamydomonas petD 5? untranslated region; petD encodes subunit IV of the cytochrome b6/f complex. These elements were delineated by linker-scanning mutagenesis, and RNA secondary structures were investigated by mapping nuclease-sensitive sites in vitro and by in vivo dimethyl sulfate RNA modification. Element I spans a maximum of 8 nucleotides (nt) at the 5? end of the mRNA; it is essential for RNA stability and plays a role in translation. This element appears to form a small stem-loop that may interact with a previously described nucleus-encoded factor to block 5??3? exoribonucleolytic degradation. Elements II and III, located in the center and near the 3? end of the 5? untranslated region, respectively, are essential for translation, but mutations in these elements do not affect mRNA stability. Element II is a maximum of 16 nt in length, does not form an obvious secondary structure, and appears to bind proteins that protect it from dimethyl sulfate modification. Element III spans a maximum of 14 nt and appears to form a stem-loop in vivo, based on dimethyl sulfate modification and the sequences of intragenic suppressors of element III mutations. Furthermore, mutations in element II result in changes in the RNA structure near element III, consistent with a long-range interaction that may promote translation.

Identification of two residues essential for the stringent substrate specificity and active site stability of the prokaryotic l-arginine:glycine amidinotransferase CyrA.  

PubMed

A novel prokaryotic l-arginine:glycine amidinotransferase (CyrA; EC2.1.4.1) is involved in the biosynthesis of the polyketide-derived cytotoxin cylindrospermopsin in the cyanobacterium Cylindrospermopsis raciborskii AWT250, and was previously characterized with regard to kinetic mechanism and substrate specificity [Muenchhoff J et al. (2010) FEBS J277, 3844-3860]. In order to elucidate the structure-function-stability relationship of this enzyme, two residues in its active site were replaced with the residues that occur in the human l-arginine:glycine amidinotransferase (h-AGAT) at the corresponding positions (F245N and S247M), and a double variant carrying both substitutions was also created. In h-AGAT, both of these residues are critical for the function of this enzyme with regard to substrate binding, ligand-induced structural changes, and stability of the active site. In this study, we demonstrated that both single residue replacements resulted in a dramatic broadening of substrate specificity, but did not affect the kinetic mechanism. Experiments with substrate analogues indicate that donor substrates require a carboxylate group for binding. Evidence from initial velocity studies suggests that CyrA undergoes ligand-induced structural changes that involve Phe245. Stability parameters (T(opt) and T(max) ) of the CyrA variants differed from those of wild-type CyrA. Structural flexibilities of the wild type and all three variants were comparable on the basis of dynamic fluorescence quenching, indicating that changes in T(opt) are most likely attributable to localized effects within the active site. Overall, the results indicated that these two residues are essential for both stringent substrate specificity and the active site stability and flexibility of this unique cyanobacterial enzyme.

Pmt-Mediated O Mannosylation Stabilizes an Essential Component of the Secretory Apparatus, Sec20p, in Candida albicans  

PubMed Central

Sec20p is an essential endoplasmic reticulum (ER) membrane protein in yeasts, functioning as a tSNARE component in retrograde vesicle traffic. We show that Sec20p in the human fungal pathogen Candida albicans is extensively O mannosylated by protein mannosyltransferases (Pmt proteins). Surprisingly, Sec20p occurs at wild-type levels in a pmt6 mutant but at very low levels in pmt1 and pmt4 mutants and also after replacement of specific Ser/Thr residues in the lumenal domain of Sec20p. Pulse-chase experiments revealed rapid degradation of unmodified Sec20p (38.6 kDa) following its biosynthesis, while the stable O-glycosylated form (50 kDa) was not formed in a pmt1 mutant. These results suggest a novel function of O mannosylation in eukaryotes, in that modification by specific Pmt proteins will prevent degradation of ER-resident membrane proteins via ER-associated degradation or a proteasome-independent pathway.

The spectrin-based membrane skeleton stabilizes mouse megakaryocyte membrane systems and is essential for proplatelet and platelet formation.  

PubMed

Megakaryocytes generate platelets by remodeling their cytoplasm first into proplatelets and then into preplatelets, which undergo fission to generate platelets. Although the functions of microtubules and actin during platelet biogenesis have been defined, the role of the spectrin cytoskeleton is unknown. We investigated the function of the spectrin-based membrane skeleton in proplatelet and platelet production in murine megakaryocytes. Electron microscopy revealed that, like circulating platelets, proplatelets have a dense membrane skeleton, the main fibrous component of which is spectrin. Unlike other cells, megakaryocytes and their progeny express both erythroid and nonerythroid spectrins. Assembly of spectrin into tetramers is required for invaginated membrane system maturation and proplatelet extension, because expression of a spectrin tetramer-disrupting construct in megakaryocytes inhibits both processes. Incorporation of this spectrin-disrupting fragment into a novel permeabilized proplatelet system rapidly destabilizes proplatelets, causing blebbing and swelling. Spectrin tetramers also stabilize the "barbell shapes" of the penultimate stage in platelet production, because addition of the tetramer-disrupting construct converts these barbell shapes to spheres, demonstrating that membrane skeletal continuity maintains the elongated, pre-fission shape. The results of this study provide evidence for a role for spectrin in different steps of megakaryocyte development through its participation in the formation of invaginated membranes and in the maintenance of proplatelet structure.

ESSENTIAL ROLE OF SURFACE HYDROXYLS FOR THE STABILIZATION AND CATALYTIC ACTIVITY OF TiO2-SUPPORTED GOLD NANOPARTICLES  

SciTech Connect

We report the investigation of titania supported gold catalysts prepared by magnetron sputtering. Catalysts grown on natural fumed titania were structurally unstable resulting in the rapid coarsening of 2.3 nm gold clusters into large ~20 nm gold clusters in a few days at room temperature under normal atmospheric conditions. However, treating the titania support powder to a mock-deposition-precipitation process, at pH 4 or pH 10, followed by the subsequent deposition of gold onto this treated powder produced a remarkable enhancement in gold particle stability and a 20-40 fold enhancement of catalytic activity respectively. This enhancement can not be attributed to the formation of oxygen vacancies on the TiO2 surface. Instead, it appears to be associated with the formation of strongly bound hydroxyl species on the TiO2 surface. The formation of surface hydroxyls during the deposition-precipitation method is coincidental and contributes significantly to the properties of Au/TiO2 catalysts.

A nuclear-encoded protein of prokaryotic origin is essential for the stability of photosystem II in Arabidopsis thaliana.  

PubMed Central

To understand the regulatory mechanisms underlying the biogenesis of photosystem II (PSII) we have characterized the nuclear mutant hcf136 of Arabidopsis thaliana and isolated the affected gene. The mutant is devoid of any photosystem II activity, and none of the nuclear- and plastome-encoded subunits of this photosystem accumulate to significant levels. Protein labelling studies in the presence of cycloheximide showed that the plastome-encoded PSII subunits are synthesized but are not stable. The HCF136 gene was isolated by virtue of its T-DNA tag, and its identity was confirmed by complementation of homozygous hcf136 seedlings. Immunoblot analysis of fractionated chloroplasts showed that the HCF136 protein is a lumenal protein, found only in stromal thylakoid lamellae. The HCF136 protein is produced already in dark-grown seedlings and its levels do not increase dramatically during light-induced greening. This accumulation profile confirms the mutational data by showing that the HCF136 protein must be present when PSII complexes are made. HCF136 homologues are found in the cyanobacterium Synechocystis species PCC6803 (slr2034) and the cyanelle genome of Cyanophora paradoxa (ORF333), but are lacking in the plastomes of chlorophytes and metaphytes as well as from those of rhodo- and chromophytes. We conclude that HCF136 encodes a stability and/or assembly factor of PSII which dates back to the cyanobacterial-like endosymbiont that led to the plastids of the present photosynthetic eukaryotes.

Fis Is Essential for the Stability of Linear Plasmid pBSSB1 and Affects the Motility of Salmonella enterica Serovar Typhi  

PubMed Central

pBSSB1 is a 27 kb non-bacteriophage-related linear plasmid first found in Salmonella enterica serovar Typhi (S. Typhi), but the mechanism underlying the replication of pBSSB1 is currently unknown. Previous reports showed that the factor for inversion stimulation (Fis) encoded by fis can affect the replication, transcription and other processes through binding DNA. Here, a fis deletion mutant of S. Typhi (?fis) was prepared through the homologous recombination mediated by suicide plasmid and the loss of pBSSB1 in ?fis was observed surprisingly by pulsed field gel electrophoresis (PFGE). Subsequently, the loss of pBSSB1 was verified by PCR and Southern blot. In addition, the motility of ?fis was deficient and the flagellin of ?fis could not be detected by 2-dimensional polyacrylamide gel electrophoresis. All these results show that Fis is essential for the stability of pBSSB1 and affects the motility of S. Typhi.

The Smallest Capsid Protein Mediates Binding of the Essential Tegument Protein pp150 to Stabilize DNA-Containing Capsids in Human Cytomegalovirus.  

PubMed

Human cytomegalovirus (HCMV) is a ubiquitous herpesvirus that causes birth defects in newborns and life-threatening complications in immunocompromised individuals. Among all human herpesviruses, HCMV contains a much larger dsDNA genome within a similarly-sized capsid compared to the others, and it was proposed to require pp150, a tegument protein only found in cytomegaloviruses, to stabilize its genome-containing capsid. However, little is known about how pp150 interacts with the underlying capsid. Moreover, the smallest capsid protein (SCP), while dispensable in herpes simplex virus type 1, was shown to play essential, yet undefined, role in HCMV infection. Here, by cryo electron microscopy (cryoEM), we determine three-dimensional structures of HCMV capsid (no pp150) and virion (with pp150) at sub-nanometer resolution. Comparison of these two structures reveals that each pp150 tegument density is composed of two helix bundles connected by a long central helix. Correlation between the resolved helices and sequence-based secondary structure prediction maps the tegument density to the N-terminal half of pp150. The structures also show that SCP mediates interactions between the capsid and pp150 at the upper helix bundle of pp150. Consistent with this structural observation, ribozyme inhibition of SCP expression in HCMV-infected cells impairs the formation of DNA-containing viral particles and reduces viral yield by 10,000 fold. By cryoEM reconstruction of the resulting "SCP-deficient" viral particles, we further demonstrate that SCP is required for pp150 functionally binding to the capsid. Together, our structural and biochemical results point to a mechanism whereby SCP recruits pp150 to stabilize genome-containing capsid for the production of infectious HCMV virion. PMID:23966856

NaStEP: a proteinase inhibitor essential to self-incompatibility and a positive regulator of HT-B stability in Nicotiana alata pollen tubes.  

PubMed

In Solanaceae, the self-incompatibility S-RNase and S-locus F-box interactions define self-pollen recognition and rejection in an S-specific manner. This interaction triggers a cascade of events involving other gene products unlinked to the S-locus that are crucial to the self-incompatibility response. To date, two essential pistil-modifier genes, 120K and High Top-Band (HT-B), have been identified in Nicotiana species. However, biochemistry and genetics indicate that additional modifier genes are required. We recently reported a Kunitz-type proteinase inhibitor, named NaStEP (for Nicotiana alata Stigma-Expressed Protein), that is highly expressed in the stigmas of self-incompatible Nicotiana species. Here, we report the proteinase inhibitor activity of NaStEP. NaStEP is taken up by both compatible and incompatible pollen tubes, but its suppression in Nicotiana spp. transgenic plants disrupts S-specific pollen rejection; therefore, NaStEP is a novel pistil-modifier gene. Furthermore, HT-B levels within the pollen tubes are reduced when NaStEP-suppressed pistils are pollinated with either compatible or incompatible pollen. In wild-type self-incompatible N. alata, in contrast, HT-B degradation occurs preferentially in compatible pollinations. Taken together, these data show that the presence of NaStEP is required for the stability of HT-B inside pollen tubes during the rejection response, but the underlying mechanism is currently unknown.

Thin, a Trim32 ortholog, is essential for myofibril stability and is required for the integrity of the costamere in Drosophila  

PubMed Central

Myofibril stability is required for normal muscle function and maintenance. Mutations that disrupt myofibril stability result in individuals who develop progressive muscle wasting, or muscular dystrophy, and premature mortality. Here we present our investigations of the Drosophila l(2)thin [l(2)tn] mutant. The “thin” phenotype exhibits features of the human muscular disease phenotype in that tn mutant larvae show progressive muscular degeneration. Loss-of-function and rescue experiments determined that l(2)tn is allelic to the tn locus [previously annotated as both CG15105 and another b-box affiliate (abba)]. tn encodes a TRIM (tripartite motif) containing protein highly expressed in skeletal muscle and is orthologous to the human limb-girdle muscular dystrophy type 2H disease gene Trim32. Thin protein is localized at the Z-disk in muscle, but l(2)tn mutants showed no genetic interaction with mutants affecting the Z-line–associated protein muscle LIM protein 84B. l(2)tn, along with loss-of-function mutants generated for tn, showed no relative mislocalization of the Z-disk proteins ?-Actinin and muscle LIM protein 84B. In contrast, tn mutants had significant disorganization of the costameric orthologs ?-integrin, Spectrin, Talin, and Vinculin, and we present the initial description for the costamere, a key muscle stability complex, in Drosophila. Our studies demonstrate that myofibrils progressively unbundle in flies that lack Thin function through progressive costamere breakdown. Due to the high conservation of these structures in animals, we demonstrate a previously unknown role for TRIM32 proteins in myofibril stability.

Arabidopsis BRICK1/HSPC300 is an essential WAVE-complex subunit that selectively stabilizes the Arp2/3 activator SCAR2.  

PubMed

The actin cytoskeleton dynamically reorganizes the cytoplasm during cell morphogenesis. The actin-related protein (Arp)2/3 complex is a potent nucleator of actin filaments that controls a variety of endomembrane functions including the endocytic internalization of plasma membrane , vacuole biogenesis , plasma-membrane protrusion in crawling cells , and membrane trafficking from the Golgi . Therefore, Arp2/3 is an important signaling target during morphogenesis. The evolutionarily conserved Rac-WAVE-Arp2/3 pathway links actin filament nucleation to cell morphogenesis . WAVE translates Rac-GTP signals into Arp2/3 activation by regulating the stability and/or localization of the activator subunit Scar/WAVE . The WAVE complex includes Sra1/PIR121/CYFIP1, Nap1/NAP125, Abi-1/Abi-2, Brick1(Brk1)/HSPC300, and Scar/WAVE : Defining the in vivo function of each subunit is an important step toward understanding this complicated signaling pathway. Brk1/HSPC300 has been the most recalcitrant WAVE-complex protein and has no known function. In this paper, we report that Arabidopsis brick1 (brk1) is a member of the "distorted group" of trichome morphology mutants, a group that defines a WAVE-ARP2/3 morphogenesis pathway . In this paper we provide the first strong genetic and biochemical evidence that BRK1 is a critical WAVE-complex subunit that selectively stabilizes the Arp2/3 activator SCAR2. PMID:16584883

Transcription factor TFIIF is not required for initiation by RNA polymerase II, but it is essential to stabilize transcription factor TFIIB in early elongation complexes.  

PubMed

Transcription factors TFIIB and TFIIF are both required for RNA polymerase II preinitiation complex (PIC) assembly, but their roles at and downstream of initiation are not clear. We now show that TFIIF phosphorylated by casein kinase 2 remains competent to support PIC assembly but is not stably retained in the PIC. PICs completely lacking TFIIF are not defective in initiation or subsequent promoter clearance, demonstrating that TFIIF is not required for initiation or clearance. Lack of TFIIF in the PIC reduces transcription levels at some promoters, coincident with reduced retention of TFIIB. TFIIB is normally associated with the early elongation complex and is only destabilized at +12 to +13. However, if TFIIF is not retained in the PIC, TFIIB can be lost immediately after initiation. TFIIF therefore has an important role in stabilizing TFIIB within the PIC and after transcription initiates. PMID:21896726

An evolutionarily conserved fission yeast protein, Ned1, implicated in normal nuclear morphology and chromosome stability, interacts with Dis3, Pim1/RCC1 and an essential nucleoporin.  

PubMed

We identified a novel fission yeast gene, ned1(+), with pleiotropic mutations that have a high incidence of chromosome missegregation, aberrantly shaped nuclei, overdeveloped endoplasmic reticulum-like membranes, and increased sensitivity to a microtubule destabilizing agent. Ned1 protein, which was phosphorylated in a growth-related manner, interacted in a yeast two-hybrid system with Dis3 as well as with Pim1/RCC1 (nucleotide exchange factor for Ran). Ned1 also interacted with an essential nucleoporin, a probable homologue of mammalian Nup98/96. The ned1 gene displayed a variety of genetic interactions with factors involved in nuclear transport and chromosome segregation, including the crm1 (exportin), spi1 (small GTPase Ran), pim1, and dis genes. A substitution mutation that affected the two-hybrid interaction with Dis3 increased chromosome instability, suggesting the functional importance of the interaction. Overproduction of Ned1 protein induced formation of an abnormal microtubule bundle within the nucleus, apparently independently of the spindle pole body, but dependent on pim1(+) activity. The ned1(+) gene belongs to an evolutionarily conserved gene family, which includes the mouse Lpin genes, one of whose mutations is responsible for lipodystrophy. PMID:12376568

Histone Acetyl Transferase 1 Is Essential for Mammalian Development, Genome Stability, and the Processing of Newly Synthesized Histones H3 and H4  

PubMed Central

Histone acetyltransferase 1 is an evolutionarily conserved type B histone acetyltransferase that is thought to be responsible for the diacetylation of newly synthesized histone H4 on lysines 5 and 12 during chromatin assembly. To understand the function of this enzyme in a complex organism, we have constructed a conditional mouse knockout model of Hat1. Murine Hat1 is essential for viability, as homozygous deletion of Hat1 results in neonatal lethality. The lungs of embryos and pups genetically deficient in Hat1 were much less mature upon histological evaluation. The neonatal lethality is due to severe defects in lung development that result in less aeration and respiratory distress. Many of the Hat1?/? neonates also display significant craniofacial defects with abnormalities in the bones of the skull and jaw. Hat1?/? mouse embryonic fibroblasts (MEFs) are defective in cell proliferation and are sensitive to DNA damaging agents. In addition, the Hat1?/? MEFs display a marked increase in genome instability. Analysis of histone dynamics at sites of replication-coupled chromatin assembly demonstrates that Hat1 is not only responsible for the acetylation of newly synthesized histone H4 but is also required to maintain the acetylation of histone H3 on lysines 9, 18, and 27 during replication-coupled chromatin assembly.

Essential tremor.  

PubMed

Essential tremor (ET) is one of the most common neurological diseases; although it is a disease about which we are only beginning to develop an understanding. Effective treatment options for the disorder are severely limited. The traditional view of ET as a benign, familial, monosymptomatic disorder is being replaced by one of ET as a disease or family of diseases with aetiological, clinical, and pathological heterogeneity. Recent identification of putative environmental toxins linked to ET provide hope for disease prevention through a reduction in exposure to risk factors. Pathological and genetic studies will yield new insights into disease pathogenesis and mechanisms, which may result in the development of more effective symptomatic therapies developed with an understanding of the disease biology. These insights also have the potential to form the basis for neuroprotective therapies. PMID:15664542

Characterization of in-frame proteins encoded by cvaA, an essential gene in the colicin V secretion system: CvaA* stabilizes CvaA to enhance secretion.  

PubMed Central

Colicin V (ColV), an antibacterial peptide toxin, uses a dedicated signal sequence-independent export system for its extracellular secretion in Escherichia coli. The products of at least three genes (a chromosomal tolC gene and two plasmid-born cvaA and cvaB genes) are involved in this process. To characterize the gene products, the cvaA gene was subcloned and expressed under the control of T7 RNA polymerase promoter. Two in-frame proteins, CvaA and CvaA*, were expressed and identified. DNA sequences predicted that both proteins have two potential translational initiation sites. N-terminal peptide sequencing showed that the translation of CvaA starts from a TTG, 11 amino acids upstream of the previously proposed ATG initiation site. CvaA* is translated from an upstream ATG. Expression of both CvaA and CvaA* was induced by the iron chelator 2,2'-dipyridyl, indicating that cvaA is negatively regulated at least partially by Fur. CvaA*-depleted cells were found to secrete less ColV, based on reduced activity in the supernatant, than did wild type, which was recovered by the addition of a plasmid producing CvaA*. Interestingly, CvaA*-depleted and wild-type cells had similar levels of intracellular ColV activity. Translational fusions showed that the syntheses of ColV and CvaA are not affected by CvaA* depletion. However, CvaA in CvaA*-depleted cells was less stable than that in wild-type cells, indicating that CvaA* may directly or indirectly affect the stability of CvaA. We conclude that CvaA* is not essential for ColV secretion but that it enhances the ColV secretion by stabilizing the CvaA protein.

Essential thrombocythemia  

PubMed Central

Essential thrombocythemia (ET) is an acquired myeloproliferative disorder (MPD) characterized by a sustained elevation of platelet number with a tendency for thrombosis and hemorrhage. The prevalence in the general population is approximately 30/100,000. The median age at diagnosis is 65 to 70 years, but the disease may occur at any age. The female to male ratio is about 2:1. The clinical picture is dominated by a predisposition to vascular occlusive events (involving the cerebrovascular, coronary and peripheral circulation) and hemorrhages. Some patients with ET are asymptomatic, others may experience vasomotor (headaches, visual disturbances, lightheadedness, atypical chest pain, distal paresthesias, erythromelalgia), thrombotic, or hemorrhagic disturbances. Arterial and venous thromboses, as well as platelet-mediated transient occlusions of the microcirculation and bleeding, represent the main risks for ET patients. Thromboses of large arteries represent a major cause of mortality associated with ET or can induce severe neurological, cardiac or peripheral artery manifestations. Acute leukemia or myelodysplasia represent only rare and frequently later-onset events. The molecular pathogenesis of ET, which leads to the overproduction of mature blood cells, is similar to that found in other clonal MPDs such as chronic myeloid leukemia, polycythemia vera and myelofibrosis with myeloid metaplasia of the spleen. Polycythemia vera, myelofibrosis with myeloid metaplasia of the spleen and ET are generally associated under the common denomination of Philadelphia (Ph)-negative MPDs. Despite the recent identification of the JAK2 V617F mutation in a subset of patients with Ph-negative MPDs, the detailed pathogenetic mechanism is still a matter of discussion. Therapeutic interventions in ET are limited to decisions concerning the introduction of anti-aggregation therapy and/or starting platelet cytoreduction. The therapeutic value of hydroxycarbamide and aspirin in high risk patients has been supported by controlled studies. Avoiding thromboreduction or opting for anagrelide to postpone the long-term side effects of hydrocarbamide in young or low risk patients represent alternative options. Life expectancy is almost normal and similar to that of a healthy population matched by age and sex.

NaStEP: A Proteinase Inhibitor Essential to Self-Incompatibility and a Positive Regulator of HT-B Stability in Nicotiana alata Pollen Tubes1[W][OA  

PubMed Central

In Solanaceae, the self-incompatibility S-RNase and S-locus F-box interactions define self-pollen recognition and rejection in an S-specific manner. This interaction triggers a cascade of events involving other gene products unlinked to the S-locus that are crucial to the self-incompatibility response. To date, two essential pistil-modifier genes, 120K and High Top-Band (HT-B), have been identified in Nicotiana species. However, biochemistry and genetics indicate that additional modifier genes are required. We recently reported a Kunitz-type proteinase inhibitor, named NaStEP (for Nicotiana alata Stigma-Expressed Protein), that is highly expressed in the stigmas of self-incompatible Nicotiana species. Here, we report the proteinase inhibitor activity of NaStEP. NaStEP is taken up by both compatible and incompatible pollen tubes, but its suppression in Nicotiana spp. transgenic plants disrupts S-specific pollen rejection; therefore, NaStEP is a novel pistil-modifier gene. Furthermore, HT-B levels within the pollen tubes are reduced when NaStEP-suppressed pistils are pollinated with either compatible or incompatible pollen. In wild-type self-incompatible N. alata, in contrast, HT-B degradation occurs preferentially in compatible pollinations. Taken together, these data show that the presence of NaStEP is required for the stability of HT-B inside pollen tubes during the rejection response, but the underlying mechanism is currently unknown.

[Antioxidant properties of essential oils].

By the method of capillary gas-liquid chromatography we studied antioxidant properties and stability during the storage of hexane solutions of 14 individual essential oils from black and white pepper (Piper nigrum L.), cardamom (Elettaria cardamomum L.), nutmeg (Myristica fragrans Houtt.), mace (Myristica fragrans Houtt), juniperberry (Juniperus communis L.), seed of fennel (Foeniculum vulgare Mill., var. dulce Thelling), caraway (Carvum carvi L.), dry leaves of cinnamon (Cinnamomum zeylanicum Bl.), marjoram (Origanum majorana L.), laurel (Laurus nobilis L.), ginger (Zingiber officinale L.), garlic (Allium sativum L.), and clove bud (Caryophyllus aromaticus L.). We assessed the antioxidant properties by the oxidation of aliphatic aldehyde (trans-2-hexenal) into the according carbon acid. We established that essential oils of garlic, clove bud, ginger and leaves of cinnamon have the maximal efficiency of inhibition of hexenal oxidation (80-93%), while black pepper oil has the minimal (49%). Antioxidant properties of essential oils with a high content of substituted phenols depended poorly on its concentration in model systems. We studied the changes in essential oils content during the storage of its hexane solutions for 40 days in the light and out of the light and compared it with the stability of essential oils stored for a year out of the light.

Medical equipment management strategies.

Clinical engineering professionals need to continually review and improve their management strategies in order to keep up with improvements in equipment technology, as well as with increasing expectations of health care organizations. In the last 20 years, management strategies have evolved from the initial obsession with electrical safety to flexible criteria that fit the individual institution's needs. Few hospitals, however, are taking full advantage of the paradigm shift offered by the evolution of joint Commission standards. The focus should be on risks caused by equipment failure, rather than on equipment with highest maintenance demands. Furthermore, it is not enough to consider risks posed by individual pieces of equipment to individual patients. It is critical to anticipate the impact of an equipment failure on larger groups of patients, especially when dealing with one of a kind, sophisticated pieces of equipment that are required to provide timely and accurate diagnoses for immediate therapeutic decisions or surgical interventions. A strategy for incorporating multiple criteria to formulate appropriate management strategies is provided in this article. PMID:16796335

The sophistication and reliability of its technology also won it worldwide export markets -- which is just as well since former major domestic mining sectors such as coal and potash have declined precipitously, and others such as ore mining have all but disappeared. Today, German mining equipment suppliers focus strongly on export sales, and formerly unique German mining technologies such as continuous mining with bucket wheel excavators and conveyors for open pits, or plowing of underground coal longwalls are widely used abroad. The status of the German mining equipment industry is reviewed.

Equipment Operational Requirements  

SciTech Connect

The Iraq Department of Border Enforcement is rich in personnel, but poor in equipment. An effective border control system must include detection, discrimination, decision, tracking and interdiction, capture, identification, and disposition. An equipment solution that addresses only a part of this will not succeed, likewise equipment by itself is not the answer without considering the personnel and how they would employ the equipment. The solution should take advantage of the existing in-place system and address all of the critical functions. The solutions are envisioned as being implemented in a phased manner, where Solution 1 is followed by Solution 2 and eventually by Solution 3. This allows adequate time for training and gaining operational experience for successively more complex equipment. Detailed descriptions of the components follow the solution descriptions. Solution 1 - This solution is based on changes to CONOPs, and does not have a technology component. It consists of observers at the forts and annexes, forward patrols along the swamp edge, in depth patrols approximately 10 kilometers inland from the swamp, and checkpoints on major roads. Solution 2 - This solution adds a ground sensor array to the Solution 1 system. Solution 3 - This solution is based around installing a radar/video camera system on each fort. It employs the CONOPS from Solution 1, but uses minimal ground sensors deployed only in areas with poor radar/video camera coverage (such as canals and streams shielded by vegetation), or by roads covered by radar but outside the range of the radar associated cameras. This document provides broad operational requirements for major equipment components along with sufficient operational details to allow the technical community to identify potential hardware candidates. Continuing analysis will develop quantities required and more detailed tactics, techniques, and procedures.

Remote maintenance lessons learned'' on prototypical reprocessing equipment  

SciTech Connect

Hardware representative of essentially every major equipment item necessary for reprocessing breeder reactor nuclear fuel has been installed and tested for remote maintainability. This testing took place in a cold mock-up of a remotely maintained hot cell operated by the Consolidated Fuel Reprocessing Program (CFRP) within the Fuel Recycle Division at Oak Ridge National Laboratory (ORNL). The reprocessing equipment tested included a Disassembly System, a Shear System, a Dissolver System, an Automated Sampler System, removable Equipment Racks on which various chemical process equipment items were mounted, and an advanced servomanipulator (ASM). These equipment items were disassembled and reassembled remotely by using the remote handling systems that are available within the cold mock-up area. This paper summarizes the lessons learned'' as a result of the numerous maintenance activities associated with each of these equipment items. 4 refs., 3 figs., 1 tab.

Divertor Stabilization in Mirrors  

SciTech Connect

Divertor stabilization is considered as an alternative MHD stability concept for mirror-based plasma confinement systems. The discussed concept is based on thermodynamics and self-organization of magnetized plasmas, contrary to the conventional MHD stabilization, based on the presence of averaged 'magnetic well'. We show that self-organized plasma maintenance near a relaxed marginally-stable state with decreasing pressure profile can be realized in essentially non-paraxial longitudinally linked mirror cells restricted by a joint divertorlike magnetic separatrix with one or several magnetic field nulls at the plasma edge. Brief history, basic principles, and main advantages of the divertor stabilization concept are discussed.

Secure authenticated video equipment  

SciTech Connect

In the verification technology arena, there is a pressing need for surveillance and monitoring equipment that produces authentic, verifiable records of observed activities. Such a record provides the inspecting party with confidence that observed activities occurred as recorded, without undetected tampering or spoofing having taken place. The secure authenticated video equipment (SAVE) system provides an authenticated series of video images of an observed activity. Being self-contained and portable, it can be installed as a stand-alone surveillance system or used in conjunction with existing monitoring equipment in a non-invasive manner. Security is provided by a tamper-proof camera enclosure containing a private, electronic authentication key. Video data is transferred communication link consisting of a coaxial cable, fiber-optic link or other similar media. A video review station, located remotely from the camera, receives, validates, displays and stores the incoming data. Video data is validated within the review station using a public key, a copy of which is held by authorized panics. This scheme allows the holder of the public key to verify the authenticity of the recorded video data but precludes undetectable modification of the data generated by the tamper-protected private authentication key.

Seismic qualification of unanchored equipment  

SciTech Connect

This paper describes procedures used to design and qualify unanchored equipment to survive Seismic events to the PC = 4 level in a moderate seismic area. The need for flexibility to move experimental equipment together with the requirements for remote handling in a highly-radioactive non-reactor nuclear facility precluded normal equipment anchorage. Instead equipment was designed to remain stable under anticipated DBE floor motions with sufficient margin to achieve the performance goal. The equipment was also designed to accommodate anticipated sliding motions with sufficient. The simplified design criteria used to achieve these goals were based on extensive time-history simulations of sliding, rocking, and overturning of generic equipment models. The entire process was subject to independent peer review and accepted in a Safety Evaluation Report. The process provides a model suitable for adaptation to similar applications and for assessment of the potential for seismic damage of existing, unanchored equipment In particular, the paper describes: (1) Two dimensional sliding studies of deformable equipment subject to 3-D floor excitation as the basis for simplified sliding radius and sliding velocity design criteria. (2) Two dimensional rocking and overturning simulations of rigid equipment used to establish design criteria for minimum base dimensions and equipment rigidity to prevent overturning. (3) Assumed mode rocking analyses of deformable equipment models used to establish uplift magnitudes and subsequent impacts during stable rocking motions. The model used for these dynamic impact studies is reported elsewhere.

Quantitative determination of protein stability and ligand binding using a green fluorescent protein reporter system.  

PubMed

Information about the stability of proteins is paramount to determine their optimal storage or reaction conditions. It is also essential to determine protein stability in high-throughput when screening for new or improved functions of proteins obtained from large mutant libraries. In drug discovery programs, monitoring of ligand-induced stabilization effects can be used to identify lead compounds in high-throughput. These studies require expensive biophysical instrumentation and large quantities of purified proteins. To address these issues, we developed a new method, using GFP as a reporter system to quantify the stability of a protein and its ligand-associated stabilization effects that requires neither special equipment nor extensive purification steps. Here, GFP is fused to a protein of interest (POI) through a linker and is used as a reporter system for protein unfolding and aggregation. The three POIs used in this study include the Ter-binding protein Tus, glycerol kinase and chloramphenicol acetyl transferase. The fluorescent fusion protein is subjected to irreversible thermal denaturation leading to formation of aggregates, which are eliminated by a centrifugation step. The residual fluorescence of the soluble fraction can be directly related to the stability of the POI and can be quantitatively monitored using a fluorescence plate reader. The GFP-based stability assay (GFP-Basta) was able to identify stabilizing compounds and afforded a new quantitative method for the screening and ranking of ligands for three different proteins. These applications are particularly useful for drug discovery, directed evolution, structural and functional genomics. PMID:20454718

Essential drugs programmes in Africa.  

PubMed

The essential drugs concept encompasses national drug policy, selection, quantification, quality assurance, procurement, inventory control and distribution, financing, rational drug use, and training. People from all sectors and levels were involved in developing Tanzania's national drug policy which was approved in 1991. The process developing a policy in Kenya continues. The policy will allow Kenya's Ministry of Health to implement various operational changes (e.g., improvements in hospital drug management). 40 sub-Saharan African (SSA) countries have a national essential drug list (EDL). A synergistic effect results when EDLs are merged with standard treatment guidelines (STGs) (e.g., in Tanzania and Zimbabwe) or constructed with STGs and a national formulary. The Federal Ministry of Health in Nigeria designated 209 drugs as essential drugs, while Nigerian states determined their own EDLs based on these 209 drugs. Spreadsheet models use morbidity patterns, past consumption, and population to help countries quantify drug needs which are then used to determine drug procurement. Various problems with quality assurance in regional and national quality control laboratories in SSA include staff turnover, limited equipment maintenance, and lack of reagents and laboratory standard solutions. A database, structured, flexible drug registration system allows countries (e.g., Zimbabwe) to monitor drug suppliers and agents. Drug procurement has improved in countries with established procurement systems. Computers help control and manage drug inventories. Kenya, Mozambique, Tanzania, and Uganda distribute ration kits of prepackaged drug selections. Cash and carry in Ghana, hospital fees in Kenya, and community insurance schemes in Guinea Bissau are some financing schemes in SSA. The International Network for the Rational Use of Drugs is operating in Ghana, Nigeria, the Sudan, and Tanzania. Training courses in drug supply management are held in Ghana, Tanzania, and Zimbabwe.

Unattended optical surveillance equipment  

NASA Astrophysics Data System (ADS)

In many security situations, it is necessary to utilize unattended optical surveillance systems. Sandia National Laboratories has developed three optical surveillance systems which operate in the unattended surveillance mode. The first of these systems is known as the Modular Integrated Video System (MIVS). The MIVS is a microprocessor controlled video system which records scenes at selectable intervals. Each scene consists of six to ten frames recorded on a 8 mm videotape. A MIVS video recorder has the capacity to record approximately 26,000 scenes. Scenes can be recorded at intervals ranging from 1 to 99 minutes between recordings. The unit has been designed for permanent installation with facility power. The camera can be located up to 30 m from the recording module with the authentication technology protecting the cable connecting the camera to the recording unit. The Portable Surveillance unit (PSU) is a second system which has been designed for unattended operation. The PSU is designed for situations where quick set up of an optical surveillance device is required. The PSU operates in a manner similar to the MIVS and can be operated off of facility power for long time periods, or from an internal battery pack for short term surveillance applications. The Video Surveillance Unit (VSU) provides similar capabilities for permanent rack mounted installations. This paper describes the MIVS, the PSU, and the VSU, and discusses potential applications for the system. Equipment for reviewing the videotapes produced by the systems is also described.

Laptop image transmission equipment  

NASA Astrophysics Data System (ADS)

Imagery and other visual information have become a critical element in planning and performing modern military operations. The effectiveness of this imagery information is often directly tied to the time it takes to get from the collector of this imagery to the user of the imagery. Hard copy distribution of annotated imagery to the tactical commander is hampered by the lack of effective communications paths, and the tactical use of hand held imagery is restricted by the lack of film processing facilities. The military has begun to rely on electronic imagery and digital communications technology for answers, with some success. The new obstacles created by applied electronic imagery are interoperability standards and effective use of communications bandwidth in a tactical environment. New technological developments in computer hardware/software have changed this situation by allowing for the gathering, dissemination, and transfer of near-real-time information to various intelligence audiences at any location. The Naval Air Development Center (NAVAIRDEVCEN) has coupled commercial-off-the-shelf (COTS) technology with National Image Transmission Formats (NITF) Standards to develop a Secondary Imagery Dissemination System (SIDS) package that is designed to meet the flexibility challenge of the tactical military environment. This tailorable SIDS package is called Laptop Image Transmission Equipment (LITE). The LITE system is an extension of the Navy's existing Fleet Imagery Support Terminal (FIST) into the man-portable tactical environment. As such, LITE development is focused on developing flexible imagery input (from sources such as filmless cameras) and connectivity to tactical communications paths and ruggedization/miniaturization issues. The LITE system, in prototype form, has already found application through operational use in special operations, counter narcotics operations, and classic air/ground/sea military operations. This paper provides an overview of the LITE components, specifications, operations, and future developments for the system.

The vast majority of essential genes were categorized in relatively few domains of cell metabolism, with about half involved in information processing, one-fifth involved in the synthesis of cell envelope and the determination of cell shape and division, and one-tenth related to cell energetics. Only 4% of essential genes encode unknown functions. Most essential genes are present throughout a wide range of Bacteria, and almost 70% can also be found in Archaea and Eucarya. However, essential genes related to cell envelope, shape, division, and respiration tend to be lost from bacteria with small genomes. Unexpectedly, most genes involved in the Embden-Meyerhof-Parnas pathway are essential. Identification of unknown and unexpected essential genes opens research avenues to better understanding of processes that sustain bacterial life. PMID:12682299

A compact equipment package for vestibular experiments during spaceflight  

NASA Astrophysics Data System (ADS)

A compact measurement and stimulus equipment package for vestibular testing is described. The package is designed on a modular concept so that a customized version can be assembled for each experimental situation. Although primarily conceived for space-related research, the equipment has also been introduced successfully into the clinical diagnostic procedure. An essential function of the equipment is the recording and evaluation of eye movements. This is performed by a video-based measurement system which permits evaluation of horizontal, vertical and torsional components of eye movement. Objective testing of the vestibulo-ocular reflex in all three orthogonal planes is therefore possible. Furthermore evaluation of the otolithic function in weightlessness is made feasible by the possibility of measuring dynamic ocular counterrolling. Some applications of the equipment are described.

Gene knockout using transcription activator-like effector nucleases (TALENs) reveals that human NDUFA9 protein is essential for stabilizing the junction between membrane and matrix arms of complex I.  

PubMed

Transcription activator-like effector nucleases (TALENs) represent a promising approach for targeted knock-out of genes in cultured human cells. We used TALEN-technology to knock out the nuclear gene encoding NDUFA9, a subunit of mitochondrial respiratory chain complex I in HEK293T cells. Screening for the knock-out revealed a mixture of NDUFA9 cell clones that harbored partial deletions of the mitochondrial N-terminal targeting signal but were still capable of import. A cell line lacking functional copies of both NDUFA9 alleles resulted in a loss of NDUFA9 protein expression, impaired assembly of complex I, and cells incapable of growth in galactose medium. Cells lacking NDUFA9 contained a complex I subcomplex consisting of membrane arm subunits but not marker subunits of the matrix arm. Re-expression of NDUFA9 restored the defects in complex I assembly. We conclude that NDUFA9 is involved in stabilizing the junction between membrane and matrix arms of complex I, a late assembly step critical for complex I biogenesis and activity. PMID:23223238

Nutritional essentiality of vanadium  

SciTech Connect

Evidence to support the essentiality of vanadium is inconclusive. Thus, it cannot be unequivocally stated that vanadium is an essential nutrient. The basis for this statement can be appreciated more fully if the following definitions are accepted. In this section, a substance is considered nutritionally essential if a dietary deficiency consistently results in a suboptimal biological function that is preventable or reversible by physiological amounts of the element. In this definition, physiological is construed as those quantities usually found in biological material. For vanadium, the usual amounts are measured in nanograms per gram, or parts per billion. The other term that should be defined is pharmacologic action. Here it means the effect of a relatively high dietary intake of a substance that alleviates an abnormality caused by something other than a nutritional deficiency.

Psychological essentialism in children.  

PubMed

Psychological essentialism is the idea that certain categories, such as "lion" or "female", have an underlying reality that cannot be observed directly. Where does this idea come from? This article reviews recent evidence suggesting that psychological essentialism is an early cognitive bias. Young children look beyond the obvious in many converging ways: when learning words, generalizing knowledge to new category members, reasoning about the insides of things, contemplating the role of nature versus nurture, and constructing causal explanations. These findings argue against the standard view of children as concrete thinkers, instead claiming that children have an early tendency to search for hidden, non-obvious features. PMID:15350241

Quality assurance for diagnostic imaging equipment  

SciTech Connect

This report addresses factors that influence production of an image. It contains the necessary information to enable the imaging physician to report the diagnostic findings to the referring physician. Some of these factors are human, other are inherent to technique and equipment. The subject of the report is quality assurance, i.e., all of the management practices instituted by the imaging physician, to assure highest quality medical care, but an essential element of quality assurance is quality control. The first three sections are concerned with quality assurance in general and the remainder with quality control in specific circumstances. This report provides a systematic approach to procedures which can ensure that the physician and the imaging facility consistently achieve their optimal performance. This in turn, ensures that there is optimal use of radiation and that radiation exposures to patient and staff are maintained at a level consistent with the principles of optimization of radiation protection espoused by the NCRP.

Measurements and Modelling of Plasma Ashing Equipment  

NASA Astrophysics Data System (ADS)

Ashing is an important stage of certain plasma-aided manufacturing processes, such as production of printer components. Ashing is essentially a dry surface cleaning process, which may also change the chemical character of the surface in desirable ways. The ashing equipment under consideration consists of two regions separated by a diffuser plate or showerhead. A mixture of oxygen and nitrogen gases at a pressure of approximately 850 mTorr flows into the upstream region where a plasma is excited by a microwave source with a power of about 1 kW. The efflux from this microwave discharge flows though a showerhead into the downstream chamber with a volume of approximately 11.5 l. This chamber contains the workpiece, which is attached to radio-frequency powered electrode excited at a frequency of 13.56 MHz with a power of approximately 200 W. The workpiece is therefore exposed to energetic ions produced by the downstream capacitive discharge and a flux of radicals produced predominantly in the upstream source. In this paper we will present an experimental characterisation of the downstream plasma using Langmuir probes, mass spectrometry and optical emission spectroscopy. We will also discuss a global model representation of this equipment, in which the problem of transport through the showerhead will be addressed.

Gender and Psychological Essentialism  

PubMed Central

SUMMARY When individuals reason in an essentialist way about social categories, they assume that group differences reflect inherently different natures (Gelman, 2003; Rothbart & Taylor, 1992). This paper describes the psychological and social implications of essentialist beliefs, and examines the extent to which children exhibit psychological essentialism when reasoning about gender. The authors discuss reasons young children as well as older children show essentialist reasoning in some contexts, but not in others. Finally, the authors suggest directions for future research, and discuss a primary challenge to many working in this field: reduction of rigid gender beliefs.

Guanfacine in essential hypertension  

PubMed Central

1 The acute and chronic effects of guanfacine on blood pressure, plasma noradrenaline concentration and plasma renin activity were investigated in 23 patients (15 males, 8 females) with essential hypertension (WHO grade I-II). 2 Guanfacine induced a decrease in plasma noradrenaline concentration and plasma renin activity concomitant with a fall in blood pressure and heart rate in both the acute and the chronic study. 3 The adrenergic response to upright posture, reflected by an increase in plasma noradrenaline concentration and plasma renin activity, was not abolished after chronic guanfacine therapy. 4 The decrease in blood pressure 15 min after intravenous administration of guanfacine was inversely correlated with the basal sympathetic activity before treatment and with the decrease in plasma noradrenaline. 5 After chronic treatment with guanfacine no significant correlation existed between blood pressure reduction and the concomitant changes in peripheral sympathetic and/or plasma renin activity. 6 Despite the lack of a close correlation it is suggested that the antihypertensive effect of guanfacine in patients with essential hypertension is at least partially mediated by an inhibition of the sympathetic nervous and plasma renin activity.

Technical support for biomedical equipment decision making.  

PubMed

Biomedical equipment in a hospital is diagnostic, therapeutic, monitoring, communication, and recordkeeping equipment that is directly or indirectly connected to the patient. This equipment continues to proliferate as developments in microcircuitry allow it to be smaller, more flexible, and thus more adaptable. One result of the equipment's increased flexibility is the ability to integrate individual equipment, clinician-users, patients, and hospital facilities into complex systems that enable the hospital to enhance patient care. Therefore, decision making regarding the acquisition and use of new equipment in the hospital must take into account the potential impact of the equipment on all the other elements of the system, including clinical and support staffs.

Effects of equipment loadings on geosynthetic-lined slope behaviour.  

PubMed

When combined in the lining and covering of waste-containment facilities, soil and geosynthetic components protect the environment by acting as a hydraulic barrier. Equipment loading may significantly increase the tensile stress induced in geosynthetic components, leading to a potential stability problem. Large equipment loadings may also result in a localized circular slip surface during construction operations. New analytical method based on discrete element modelling is proposed for estimating the distribution of tensile force developed in the individual geosynthetic components of the lining system and for evaluating the safety factor of slope failure due to equipment loading. The analytical results of an example are presented to demonstrate the applicability of the analytical method for the lining system of a waste landfill. The analyses of the example show that equipment loading provide a substantial increase in the tensile forces of the geosynthetic components of a lining system and that the possibility of shallow failure due to equipment loading increases as the slope becomes steeper. This method is a useful tool for analysing the lining system of waste landfills with complex lining components. PMID:15988943

Network Stability  

NASA Astrophysics Data System (ADS)

Stability resembles intelligence: easy to imagine and hard to define. Here I will assess network stability at three different levels. First I will describe network perturbations and the concept of local dissipation and global connections. Later a number of different scenarios will be shown, where the perturbation is big or persistent enough to change the stability of the underlying bottom networks, and therefore, the structure of the current network is not preserved. Then stability relationships between the bottom and top networks will be discussed using the example of synchrony. Finally, I will describe the two basic design alternatives: evolution and engineering.

Genetics of essential tremor.  

PubMed

Essential tremor (ET), the cause of which remains poorly understood, is one of the most common neurological disorders. While environmental agents have been proposed to play a role, genetic factors are believed to contribute to its onset. Thus far, three gene loci (ETM1 on 3q13, ETM2 on 2p24.1 and a locus on 6p23) have been identified in patients and families with the disorder. In addition, a Ser9Gly variant in the dopamine D3 receptor gene on 3q13 has been suggested to be a risk factor. Moreover, genetically deficient animal models express a phenotype that overlaps with some clinical characteristics of the human form of the illness. Further analyses of these genetic abnormalities may lead to the identification of causative mutations and a better understanding of the molecular mechanisms in this common movement disorder.

Headache in essential thrombocythaemia  

PubMed Central

Headache is frequently reported as one of the neurological manifestations of essential thrombocythaemia (ET) and other myeloproliferative neoplasms. It is associated with considerable morbidity; yet, it is a frequently under-recognised symptom. In patients with ET, headaches may be attributable to the disease, to the prescribed ET treatment, or unrelated to ET. The majority of headaches in ET are self-limiting and can be managed with standard headache therapies such as paracetamol, but it is vital that the clinician managing these conditions is able to recognise the headaches with a more sinister pathology. In this article, we will review the incidence and management of headaches in ET, whether they are primarily related to the disease or a result of its treatment. Identification of specific headache types in patients with ET may enable physicians to employ the most effective headache medication. This would enhance the patient-physician relationship, increasing patient compliance and thus reducing the risk of adverse outcomes.

This is an introduction to the major concepts in total quality management, a loose collection of management approaches that focus on continuous improvement of processes, guided by routine data collection and adjustment of the processes. Customer focus and involvement of all members of an organization are also characteristics commonly found in TQM. The seventy-five-year history of the movement is sketched from its beginning in statistical work on quality assurance through the many improvements and redefinitions added by American and Japanese thinkers. Essential concepts covered include: control cycles, focus on the process rather than the defects, the GEAR model, importance of the customer, upstream quality, just-in-time, kaizen, and service quality.

Computing absolute and essential spectra using continuation  

NASA Astrophysics Data System (ADS)

A continuation approach to the computation of essential and absolute spectra of differential operators on the real line is presented. The advantages of this approach, compared with direct eigenvalue computations for the discretized operator, are the efficient and accurate computation of selected parts of the spectrum (typically those near the imaginary axis) and the option to compute nonlinear travelling waves and selected eigenvalues or other stability indicators simultaneously in order to locate accurately the onset to instability. We also discuss the implementation and usage of this approach with the software package AUTO and provide example computations for the FitzHugh Nagumo and the complex Ginzburg Landau equation.

Strategy Guideline: HVAC Equipment Sizing  

SciTech Connect

The heating, ventilation, and air conditioning (HVAC) system is arguably the most complex system installed in a house and is a substantial component of the total house energy use. A right-sized HVAC system will provide the desired occupant comfort and will run efficiently. This Strategy Guideline discusses the information needed to initially select the equipment for a properly designed HVAC system. Right-sizing of an HVAC system involves the selection of equipment and the design of the air distribution system to meet the accurate predicted heating and cooling loads of the house. Right-sizing the HVAC system begins with an accurate understanding of the heating and cooling loads on a space; however, a full HVAC design involves more than just the load estimate calculation - the load calculation is the first step of the iterative HVAC design procedure. This guide describes the equipment selection of a split system air conditioner and furnace for an example house in Chicago, IL as well as a heat pump system for an example house in Orlando, Florida. The required heating and cooling load information for the two example houses was developed in the Department of Energy Building America Strategy Guideline: Accurate Heating and Cooling Load Calculations.

Impacts of Voltage Sags and Protection Coordination on Sensitive Equipment in Distribution Systems  

NASA Astrophysics Data System (ADS)

Nowadays, a lot of sensitive electronic equipment is widely used in modern power systems such as power converters and adjustable speed drivers. Voltage sags have gained more interest due to their consequences on the performance of sensitive equipment (SE). Malfunction or failure of the equipment that leads to work or production losses can be caused by voltage sags. As a result, it is essential to have information on equipment sensitivity. If the magnitude and duration of voltage sag exceed the equipment sensitivity threshold, the equipment can malfunction, and such a consequence can affect an entire automatic process, resulting in high economical losses. Reclosers and fuses are the main overcurrent protection devices in distribution systems. Poor coordination may adversely impact on the sensitive equipment. This paper presents a method to analyze impacts of voltage sags and protection coordination on sensitive equipment. A fault position method and mathematical equations describing characteristics of protection devices are used to calculate voltage sags and the protection settings. Voltage tolerance thresholds and protective device characteristics are used to analyze protection and sensitive equipment coordination. Based on the results, new settings for protective devices can be adjusted for sensitive equipment in distribution systems. The Roy Billinton Test System (RBTS) bus 2 is used to analyze impacts of voltage sags and protection coordination.

Zinc: An Essential Micronutrient  

PubMed Central

Zinc is an essential micronutrient for human metabolism that catalyzes more than 100 enzymes, facilitates protein folding, and helps regulate gene expression. Patients with malnutrition, alcoholism, inflammatory bowel disease, and malabsorption syndromes are at an increased risk of zinc deficiency. Symptoms of zinc deficiency are nonspecific, including growth retardation, diarrhea, alopecia, glossitis, nail dystrophy, decreased immunity, and hypogonadism in males. In developing countries, zinc supplementation may be effective for the prevention of upper respiratory infection and diarrhea, and as an adjunct treatment for diarrhea in malnourished children. Zinc in combination with antioxidants may be modestly effective in slowing the progression of intermediate and advanced age-related macular degeneration. Zinc is an effective treatment for Wilson disease. Current data do not support zinc supplementation as effective for upper respiratory infection, wound healing, or human immunodeficiency virus. Zinc is well tolerated at recommended dosages. Adverse effects of long-term high-dose zinc use include suppressed immunity, decreased high-density lipoprotein cholesterol levels, anemia, copper deficiency, and possible genitourinary complications.

Liquid-Liquid Extraction Equipment  

SciTech Connect

Solvent extraction processing has demonstrated the ability to achieve high decontamination factors for uranium and plutonium while operating at high throughputs. Historical application of solvent extraction contacting equipment implies that for the HA cycle (primary separation of uranium and plutonium from fission products) the equipment of choice is pulse columns. This is likely due to relatively short residence times (as compared to mixer-settlers) and the ability of the columns to tolerate solids in the feed. Savannah River successfully operated the F-Canyon with centrifugal contactors in the HA cycle (which have shorter residence times than columns). All three contactors have been successfully deployed in uranium and plutonium purification cycles. Over the past 20 years, there has been significant development of centrifugal contactor designs and they have become very common for research and development applications. New reprocessing plants are being planned in Russia and China and the United States has done preliminary design studies on future reprocessing plants. The choice of contactors for all of these facilities is yet to be determined.

Problem Stabilization  

PubMed Central

Background Public health nurse (PHN) home visiting programs have been widely employed to improve life course trajectories for high risk mothers. Home visiting programs are often lengthy, during which PHNs simultaneously address multiple problems using diverse interventions over several client encounters. To manage PHN caseloads it is critical to understand the trajectory of client improvement and the optimal duration or services. PHN documentation data enable intervention trajectory research for specific client problems. A new metric called problem stabilization is proposed for evaluating interim improvement during PHN home visiting. Problem stabilization is an intervention pattern for a client problem that is characterized by co-occurring actions (i.e. teaching, guidance, and counseling; treatments and procedures; case management; and/or surveillance) during a client encounter; followed by surveillance actions only for that problem during a subsequent client encounter. The purpose of the study was to investigate problem stabilization during home visiting services for high risk mothers. Methods A retrospective cohort was created using family home visiting intervention documentation data from a local Midwest public health agency over a six year period (2000–2005). The data set consisted of Omaha System interventions for 720 high risk mothers. Analysis was conducted using descriptive statistics and Kaplan Meier curves. Results On average 30.1% of the time, client problems stabilized before discharge. Stabilization patterns differed by problem. Time to stabilization was longest for Caretaking/parenting and Antepartum/postpartum problems, and shortest for Residence and Mental health problems. Conclusions Problem stabilization, a proposed intermediate outcome of PHN home visiting care, appears to be meaningful in describing client response to PHN intervention. This metric is an example of meaningful use of structured clinical electronic health record data for program evaluation and clinical decision support.

Next-generation automatic test equipment for military support  

NASA Astrophysics Data System (ADS)

The underlying philosophy and design of automatic testing equipment (ATE) for military systems have undergone modification in view of the increasingly important requirement of forward deployment. ATE stations must accordingly become smaller and lighter for the sake of transportability, as well as hardier and easily reconfigurable. Ease of operation and maintenance also become critical. Among the technologies identified as essential for the implementation of these stringent ATE design requirements are the IEE-488, MIL-STD-1553, VME, VXI, and SCSI data buses, 'instruments on a card' technology, optical disk drives, touch-screen technology, and expert system-related software.

Techniques in bone densitometry have made remarkable progress in the past quarter-century and are now widely used in the daily practice of osteoporosis. Since the skeletal site and the method of measurement differ among the type of equipments, several types are adopted to suit the situation of each medical institute. Central DXA is used to provide a thorough examination of osteoporosis in large hospitals, whereas in general clinics the radial DXA or radiographic photodensitometry of metacarpus is mainly used. Quantitative ultrasound of calcaneus is mostly used for screening osteoporosis. DXA is also going to be applied to vertebral fracture assessment, hip structural analysis and micro-architectural analysis of vertebral trabecular bone. PMID:23445883

Purex: process and equipment performance  

SciTech Connect

The Purex process is the solvent extraction system that uses tributyl phosphate as the extractant for separating uranium and plutonium from irradiated reactor fuels. Since the first flowsheet was proposed at Oak Ridge National Laboratory in 1950, the process has endured for over 30 years with only minor modifications. The spread of the technology was rapid, and worldwide use or research on Purex-type processes was reported by the time of the 1955 Geneva Conference. The overall performance of the process has been so good that there are no serious contenders for replacing it soon. This paper presents: process description; equipment performance (mixer-settlers, pulse columns, rapid contactors); fission product decontamination; solvent effects (solvent degradation products); and partitioning of uranium and plutonium.

Drebrin preserves endothelial integrity by stabilizing nectin at adherens junctions.  

PubMed

Regulation of cell-cell contacts is essential for integrity of the vascular endothelium. Here, a critical role of the F-actin-binding protein drebrin in maintaining endothelial integrity is revealed under conditions mimicking vascular flow. Drebrin knockdown leads to weakening of cell-cell contacts, characterized by loss of nectin from adherens junctions and its subsequent lysosomal degradation. Immunoprecipitation, FRAP and mitochondrial re-targeting experiments show that nectin stabilization occurs through a chain of interactions: drebrin binding to F-actin, interaction of drebrin and afadin through their polyproline and PR1-2 regions, and recruitment of nectin through the PDZ region of afadin. Key elements are modules in drebrin that confer binding to afadin and F-actin. Evidence for this was obtained using constructs containing the PDZ region of afadin coupled to the F-actin-binding region of drebrin or to lifeact, which restore junctional nectin under knockdown of drebrin or of both drebrin and afadin. Drebrin, containing binding sites for both afadin and F-actin, is thus uniquely equipped to stabilize nectin at endothelial junctions and to preserve endothelial integrity under vascular flow.

Visual stability.

Our vision remains stable even though the movements of our eyes, head and bodies create a motion pattern on the retina. One of the most important, yet basic, feats of the visual system is to correctly determine whether this retinal motion is owing to real movement in the world or rather our own self-movement. This problem has occupied many great thinkers, such as Descartes and Helmholtz, at least since the time of Alhazen. This theme issue brings together leading researchers from animal neurophysiology, clinical neurology, psychophysics and cognitive neuroscience to summarize the state of the art in the study of visual stability. Recently, there has been significant progress in understanding the limits of visual stability in humans and in identifying many of the brain circuits involved in maintaining a stable percept of the world. Clinical studies and new experimental methods, such as transcranial magnetic stimulation, now make it possible to test the causal role of different brain regions in creating visual stability and also allow us to measure the consequences when the mechanisms of visual stability break down.

Aging assessment of essential HVAC chillers used in nuclear power plants  

SciTech Connect

The Pacific Northwest Laboratory conducted a comprehensive aging assessment of chillers used in the essential safety air-conditioning systems in nuclear power plants (NPPs). The chillers used, and air-conditioning systems served, vary in design from plant to plant. The review of operating experience indicated that chillers experience aging degradation and failures. The primary aging factors of concern for chillers include vibration, excessive temperatures and pressures, thermal cycling, chemical attack, and poor quality cooling water. The evaluation of Licensee Event Reports (LERs) indicated that about 38% of the failures were primarily related to aging, 55% were partially aging related, and 7% of the failures were unassignable. About 25% of the failures were primarily caused by human, design, procedure, and other errors. The large number of errors is probably directly related to the complexity of chillers and their interfacing systems. Nearly all of the LERs were the result of entering plant Technical Specification Limiting Condition for Operation (LCO) that initiated remedial actions like plant shutdown procedures. The trend for chiller-related LERs has stabilized at about 0.13 LERs per plant year since 1988. Carefully following the vendor procedures and monitoring the equipment can help to minimize and/or eliminate most of the premature failures. Recording equipment performance can be useful for trending analysis. Periodic operation for a few hours on a weekly or monthly basis is useful to remove moisture and non-condensable gases that gradually build up inside the chiller. Chiller pressurization kits are available that will help minimize the amount of moisture and air ingress to low-pressure chillers during standby periods. The assessment of service life condition monitoring of chillers indicated there are many simple to sophisticated methods available that can help in chiller surveillance and monitoring.

Better metallurgy for process equipment  

SciTech Connect

Metallurgy choices have expanded significantly for process equipment and pumps used for handling difficult corrosive fluids. If they have been specifying the austenitic AISI types 316, 316L, 317, 317L or the newer first generation alloy 329 in their pumps, there is a strong message in recent literature. Based on tests and experience there are better, often less costly alternatives. In the case of CD[sub 4]MCu, N08020 and 904L, there are lower-cost material alternatives for many applications. For SA S31254 and SA N08367, there are some less aggressive can be substituted. These alternatives are the new second generation duplex steels. The lower cost of the duplex alloys is a result of the reduced nickel content, which is about half that of the standard austenitics. Also, their carbon content is low; the same as 316L and 317L for most alloys, including S31803. The second generation duplex alloys offer significant value improvement in a vast majority of applications over the common austenitics and ferritics. Further, their improved resistance to corrosion and improved physical properties relative to the expensive. and in many cases proprietary, highly corrosion-resistant, super-ferritics and super-austenitics, means that they can and should be considered as an alternative for applications where those materials are now overqualified. Strength, toughness and wide corrosion resistance are all-important properties and considerations for process pump materials. Combine these with competitive cost and there is an opportunity that must be investigated.

Export of electronics equipment waste.  

PubMed

Electronics equipment waste ("e-waste") includes discarded computers, computer monitors, television sets, and cell phones. Less than 10% of e-waste is currently recycled. The United States and other developed countries export e-waste primarily to Asia, knowing it carries a real harm to the poor communities where it will be discarded. A 2006 directive bans the use of lead, mercury, cadmium, hexavalent chromium, and certain brominated flame retardants in most electronics products sold in the EU. A similar directive facilitates the development and design of clean electronics products with longer lifespans that are safe and easy to repair, upgrade, and recycle, and will not expose workers and the environment to hazardous chemicals. These useful approaches apply only regionally and cover only a fraction of the hazardous substances used in electronics manufacture, however. There is an urgent need for manufacturers of electronics products to take responsibility for their products from production to end-of-life, and for much tighter controls both on the transboundary movement of e-waste and on the manner in which it is recycled. Manufacturers must develop clean products with longer lifespans that are safe and easy to repair, upgrade, and recycle and will not expose workers and the environment to hazardous chemicals.

ISS qualified thermal carrier equipment  

NASA Astrophysics Data System (ADS)

Biotechnology is undergoing a period of rapid and sustained growth, a trend which is expected to continue as the general population ages and as new medical treatments and products are conceived. As pharmaceutical and biomedical companies continue to search for improved methods of production and, for answers to basic research questions, they will seek out new avenues of research. Space processing on the International Space Station (ISS) offers such an opportunity! Space is rapidly becoming an industrial laboratory for biotechnology research and processing. Space bioprocessing offers exciting possibilities for developing new pharmaceuticals and medical treatments, which can be used to benefit mankind on Earth. It also represents a new economic frontier for the private sector. For over eight years, the thermal carrier development team at SHOT has been working with government and commercial sector scientists who are conducting microgravity experiments that require thermal control. SHOT realized several years ago that the hardware currently being used for microgravity thermal control was becoming obsolete. It is likely that the government, academic, and industrial bioscience community members could utilize SHOT's hardware as a replacement to their current microgravity thermal carrier equipment. Moreover, SHOT is aware of several international scientists interested in utilizing our space qualified thermal carrier. SHOT's economic financing concept could be extremely beneficial to the international participant, while providing a source of geographic return for their particular region. Beginning in 2000, flight qualified thermal carriers are expected to be available to both the private and government sectors. .

Temporary equipment may be brought onto a plant site for a variety of process needs. The risk profile of the facility is altered by use of such temporary equipment, but since the time durations of temporary equipment usage are generally small, usually fewer than 90 days per year, the risk increase is also small and is typically not modeled in a probabilistic risk assessment. This article describes some risk issues with temporary equipment in long-term use, gives a case study of a temporary, diesel-driven air compressor under extended use at the Idaho National Laboratory, and suggests the need to model temporary equipment in the facility risk assessment if the equipment is used more than a few months.

Anesthesia equipment malfunction: origins and clinical recognition.  

PubMed Central

Equipment malfunction is a problem of particular importance during anesthesia and resuscitation. A review of published reports shows that the most common clinical events involve endotracheal tubes, the inspired oxygen concentration, the volume of inspired anesthetic vapours and gases, and pressures in the breathing or ventilation system. It is concluded that protection of a patient from equipment malfunction depends on: (a) appropriate application of standards set by a national standards association; (b) careful evaluation of equipment prior to purchase; (c) comprehension of equipment function by the user; (d) conscientious routine servicing of all systems concerned with anesthesia and resuscitation, and checking after service and before clinical use; (e) preanesthesia testing of equipment, including the use of an oxygen analyser in the breathing circuit; (f) early inclusion of equipment malfunction in the differential diagnosis of events during anesthesia; and (g) rapid action that cannot present a new hazard to the patient to correct the results of apparatus malfunction.

[Quality evaluation of essential oils].  

PubMed

Essential oils on the market were analyzed using GC-MS and the main ingredients of each essential oil were quantified. Analysis of the essential oil of Lavandula officinalis (lavender oil) showed that each sample had a different ratio of the contents of main ingredients, such as linalool, linalyl acetate, and camphor. In addition, some commercial lavender oils were analyzed by GC-MS for comparison with the Lavandula flagrans (lavandin oil) and the reference standard. As a result of this analysis, although the components of almost all commercial lavender oils were approximately the same as those of the reference standard, there were a few products that contained more than 0.5% of the amount of camphor in lavandin oil. This suggests that some lavender oil samples are mixed with lavandin oil to lower the price. Commercial essential oils of Melaleuca alternifolia (teatree oil) and Mentha piperita (peppermint oil) were also analyzed by GC-MS. Each of the peppermint oil samples had a different ratio in the content of its main ingredient. With respect to teatree oils, the amount of terpinens in each sample differed. These results led to concern about the efficacy of essential oils. For achieve the expected efficacy of essential oils, correct information on their ingredients should be available and quality control using instrumental analysis should be introduced. PMID:11905050

Seismic qualification of equipment by means of probabilistic risk assessment. [PWR  

SciTech Connect

Upon the sponsorship of the Equipment Qualification Branch (EQB) of NRC, Brookhaven National Laboratory (BNL) has utilized a risk-based approach for identifying, in a generic fashion, seismically risk-sensitive equipment. It is anticipated that the conclusions drawn therefrom and the methodology employed will, in part, reconcile some of the concerns dealing with the seismic qualification of equipment in operating plants. The approach taken augments an existing sensitivity analysis, based upon the WASH-1400 Reactor Safety Study (RSS), by accounting for seismicity and component fragility with the Kennedy model and by essentially including the requisite seismic data presented in the Zion Probabilistic Safety Study (ZPSS). Parametrically adjusting the seismic-related variables and ascertaining their effects on overall plant risk, core-melt probability, accident sequence probability, etc., allows one to identify those seismically risk-sensitive systems and equipment. This paper describes the approach taken and highlights the results obtained thus far for a hypothetical pressurized water reactor (PWR).

Office information technologies are using an increasing amount of energy in commercial buildings. During recent forecasting hearings in California, the office equipment end use has been a major source of differences among forecasts of commercial sector energy use. Not only are there major differences in forecasted load growth resulting from the energy use of office equipment, but there are also differences in interpretations of historical and base-year estimates. Understanding office equipment energy use is particularly important because office equipment is widely believed to be the fastest growing electrical end use in the fastest growing sector. This report describes the development and application of a spreadsheet to estimate current and future energy use by office equipment. We define the term ``office equipment`` to mean information processing technologies used in buildings. The seven categories of office equipment relate to categories found in our analysis of utility surveys and industry sales reports. These seven categories of equipment are examined for eleven types of commercial buildings.

The evolution of biomedical equipment technology.  

PubMed

This feature article presents an overview of how the biomedical equipment technology field developed. It begins with some of the early medical equipment breakthroughs, such as the discovery of X rays. The article then traces the key role of the military in electronic technology design, leading to the concept of specially trained individuals to maintain medical equipment. The Technical Education Research Center is discussed, along with the evolution of BMET schools. Formal BMET education had a strong advocate in Ralph Nader, whose concerns about electrical safety in hospitals supported the need for trained technicians to test medical equipment. BMET certification, BMET careers, and Clinical Engineering are discussed. The article concludes with some speculation on healthcare reform and its possible effect on the biomedical equipment profession. PMID:10143263

An essential memory trace found.  

PubMed

I argue here that we have succeeded in localizing an essential memory trace for a basic form of associative learning and memory-classical conditioning of discrete responses learned with an aversive stimulus-to the anterior interpositus nucleus of the cerebellum. We first identified the entire essential circuit, using eyelid conditioning as the model system, and used reversible inactivation, during training, of critical structures and pathways to localize definitively the essential memory trace. In recognition of the 30th anniversary of Behavioral Neuroscience, I highlight 1 paper (Tracy, Thompson, Krupa, & Thompson, 1998) that was particularly significant for the progress of this research program. In this review, I present definitive evidence that the essential memory trace for eyelid conditioning is localized to the cerebellum and to no other part of the essential circuit, using electrical stimulation of the pontine nuclei-mossy fibers projecting to the cerebellum as the conditional stimulus (CS; it proved to be a supernormal stimulus resulting in much faster learning than with any peripheral CS) and using an electrical stimulus to the output of the cerebellum as a test, which did not change. Pontine patterns of projection to the cerebellum were confirmed with retrograde labeling techniques. (PsycINFO Database Record (c) 2013 APA, all rights reserved). PMID:24128356

Radiotherapy equipment--purchase or lease?  

PubMed

Against a background of increasing demand for radiotherapy equipment, this study was undertaken to investigate options for equipment procurement, in particular to compare purchase with lease. The perceived advantages of lease are that equipment can be acquired within budget and cashflow constraints, with relatively low amounts of cash leaving the NHS in the first year, avoiding the necessity of capitalizing the equipment and providing protection against the risk of obsolescence associated with high technology equipment. The perceived disadvantages of leasing are that the Trust does not own the equipment, leasing can be more expensive in revenue terms, the tender process is extended and there may be lease conditions to be met, which may be costly and/or restrictive. There are also a number of technical considerations involved in the leasing of radiotherapy equipment that influence the financial analysis and practical operation of the radiotherapy service. The technical considerations include servicing and planned preventative maintenance, upgrades, spare parts, subsequent purchase of "add ons", modification of equipment, research and development work, commencement of the lease period, return of equipment at the end of the lease period and negotiations at the end of the lease period. A study from Raigmore Hospital, Inverness is described, which involves the procurement of new, state-of-the-art radiotherapy equipment. This provides an overview of the procurement process, including a summary of the advantages and disadvantages of leasing, with the figures from the financial analysis presented and explained. In addition, a detailed description is given of the technical considerations to be taken into account in the financial analysis and negotiation of any lease contract. PMID:11511499

Turbulence stabilization  

NASA Astrophysics Data System (ADS)

We recently developed a new approach to get a stabilized image from a sequence of frames acquired through atmospheric turbulence. The goal of this algorihtm is to remove the geometric distortions due by the atmosphere movements. This method is based on a variational formulation and is efficiently solved by the use of Bregman iterations and the operator splitting method. In this paper we propose to study the influence of the choice of the regularizing term in the model. Then we proposed to experiment some of the most used regularization constraints available in the litterature.

Cultural transmission of social essentialism  

PubMed Central

Social essentialism entails the belief that certain social categories (e.g., gender, race) mark fundamentally distinct kinds of people. Essentialist beliefs have pernicious consequences, supporting social stereotyping and contributing to prejudice. How does social essentialism develop? In the studies reported here, we tested the hypothesis that generic language facilitates the cultural transmission of social essentialism. Two studies found that hearing generic language about a novel social category diverse for race, ethnicity, age, and sex led 4-y-olds and adults to develop essentialist beliefs about that social category. A third study documented that experimentally inducing parents to hold essentialist beliefs about a novel social category led them to produce more generic language when discussing the category with their children. Thus, generic language facilitates the transmission of essentialist beliefs about social categories from parents to children.

CE Marking - the Essential Requirements  

NASA Astrophysics Data System (ADS)

The European Union (EU) harmonisation project introduced the CE marking of products to enable the free, unhindered movement of goods throughout the European market. The CE mark replaced the EC mark in the mid 1990s and is fundamental to the New Approach Directives. When a product falls within the scope of a New Approach Directive the manufacturer must comply with the 'goal setting' essential requirements of the directive, to follow one of the conformity assessment procedures provided for, and to draw up the technical documentation specified. Although not mandatory, a manufacturer can choose to satisfy the essential requirements through the application of European harmonised standards.

SCADA Data Visualization Using Equipment Graphs  

NASA Astrophysics Data System (ADS)

We present a method to visualize a large mount of monitored values of Supervisory Control And Data Acquisition (SCADA) systems on small screens of cell phones using supervised equipment and its relations. The aim is to provide easy views and navigation on small screens for operators to obtaining information about plants and to ascertain plant status in cases of emergency. In this method, pieces of equipment and relations between them form an equipment graph, and closely related pieces of equipment are shown by extracting them from the graph based on a focused piece of equipment. The relations have two characteristics: (i) there are various kinds of relations, and (ii) closeness of relations varies by viewpoints. The result of the extraction depends on the relation closeness. Users can check related pieces of equipment by a simple operation selecting another piece of equipment from displayed items and setting a viewpoint. Our experiments show the advantage of this method. The counts of screens shown to check plant status reduced to 40 %, extracted items were appropriate to show, and viewpoints were easy to select.

Remote equipment control through virtual reality feedback  

NASA Astrophysics Data System (ADS)

This paper presents a method for remotely controlling articulated equipment such as robot arms through a 'manipulation' of their virtual representation by hand held actuators. The object is to take advantage of the superior hand/eye coordination of humans together with the flexibility of scale and imagery of virtual visualization. The main difficulty lies in effectively representing control limits to the operator. This is resolved through animated representations in the virtual space. The proposed technique has applications for high resolution equipment control in hostile environments or the control of very large or very small scale equipment.

Field surveys of office equipment operating patterns  

SciTech Connect

This paper presents the results of 11 after-hours walk-throughs of offices in the San Francisco CA and Washington D.C. areas. The primary purpose of these walk-throughs was to collect data on turn-off rates for various types of office equipment (computers, monitors, printers, fax machines, copiers, and multifunction products). Each piece of equipment observed was recorded and its power status noted (e.g. on, off, low power). Whenever possible, we also recorded whether power management was enabled on the equipment. The floor area audited was recorded as well, which allowed us to calculate equipment densities. We found that only 44 percent of computers, 32 percent of monitors, and 25 percent of printers were turned off at night. Based on our observations we estimate success rates of 56 percent for monitor power management and 96 percent for enabling of power management on printers.

Survey of equipment in general practice.  

PubMed Central

Partners in general practice have to buy any equipment they want themselves. As a result partners in high investing practices have lower net incomes. Of the 297 practices in Devon and Cornwall, 265 responded to a questionnaire listing 115 possible items of practice equipment. Overall, practices seemed to be fairly well equipped. Key findings were that 193 of those who responded had an electrocardiograph, 206 had a kit for minor operations, 119 owned a computer, and less than one third owned a microscope. Most of these practices were high investors. There seems to be a shift away from some traditional instruments towards expensive information technology. Government policies are encouraging the use of computers and such equipment, though funds are not necessarily being made available for this purpose.

Understanding And Addressing Equipment Limitations Through Testing  

SciTech Connect

Safeguards demands have brought about the use of new, advanced equipment. These new systems are typically more complex than previous systems sometimes making use of dense circuitry and complex controls that can bring out previously unseen susceptibilities to various environmental conditions. In addition to possibly being susceptible to ambient conditions such as temperature and humidity, there may be a misunderstanding regarding the operational limitations of the equipment. Will a radiation detector respond to a moving source? Will other types of radiation overwhelm the response of the detector to the radiation of interest? Will the electronics survive or become incapacitated after exposure to radiation? These questions and others need to be addressed through the use of a systematic testing program. The program should not be used as a tool for criticism, but as a method of improving the reliability of equipment in the field and as a technique for improving the operation of the equipment. This document presents some of the information that was obtained at Oak Ridge National Laboratory where a series of tests were performed on various types of equipment with differing functions. Equipment tested included data transmission devices and radiation sensors. Tests performed included ionizing radiation to test for effects from interfering radiation and as a characterization tool for such things as response to moving sources. Other tests involved the use of non-ionizing radiation to determine whether interference could occur when equipment is exposed to radio frequency or magnetic field environments. The remaining tests were performed to establish whether susceptibilities exist when equipment is exposed to various temperature and humidity environments. Although more testing may be needed, the test methodologies used could provide a direction to future qualification plans.

Control and Operational Models for Vacuum Equipment  

NASA Astrophysics Data System (ADS)

Operational models which describe the behaviour and the physical values associated with the vacuum equipment as seen by an operator have been studied for some time at CERN. Recently, they have been completed by control models, which define in a formal way the data structures required to access the physical values described in the operational model. The control models also define the operations that an application program has to send to the vacuum equipment to modify its state. Object Modelling Techniques (OMT) have been used to formalise the description of the models. In order to test the validity of the concepts, we have made a working prototype in the LEP accelerator. This prototype is being built on top of the CERN SL-Equip equipment access package and uses the "cdev" C++ library, developed at TJNAF, for the interface to application programs. SL-Equip is used for data transmission between front-end computers and vacuum equipment. We use the "cdev" networking facilities to communicate between the workstation and the front-end computers, and the "cdev" generic server as the framework for implementing the vacuum controls software. These packages were used in order to minimise the required software investment, but also to prove that these models are hardware and software independent.

Essential mixed cryoglobulinemia type II.

We report a rare case of essential mixed cryoglobulinemia type II with membrano-proliferative glomerulonephritis (MPGN) type I in which HCV was not found. Long-term history of palindromic rheumatism, skin leukocytoclastic vasculitis attacks and micro-normocytic anemia preceded the appearance of cryoglobulinemia. Cryoprecipitate consisted of monoclonal IgMk-RF and polyclonal IgG (essential mixed type II). The newly appreciated cryoglobulinemia was associated with Coombs positive hemolytic anemia. The MPGN in this case had a benign course and responded to complex simple therapies including prevention of exposure to cold, low antigen content diet, treatment of provoking factors such as UTI, and maximal dose of ACE inhibitor. Responsiveness of skin vasculitis to colchicine therapy was restored after a two-month colchicine withdrawal period and therefore corticosteroid and immunosuppressive therapy was postponed.

The equipment identified in this study is based on Viability Assessment (VA) design. The ''Monitored Geologic Repository Test and Evaluation Plan'' (MGR T&EP), Reference 5.1, was used as a basis for this study. The MGR T&EP reflects the extent of test planning and analysis that can be conducted, given the current status of the MGR requirements and latest VA design information. The MGR T&EP supports the appropriate sections in the license application (LA) in accordance with 10 CFR 60.2 1(c)(14). The MGR T&EP describes the following test activities: site characterization to confirm, by test and analysis, the suitability of the Yucca Mountain site for housing a geologic repository; development testing to investigate and document design concepts to reduce risk; qualification testing to verify equipment compliance with design requirements, specifications, and regulatory requirements; system testing to validate compliance with MGR requirements, which include the receipt, handling, retrieval, and disposal of waste; periodic performance testing to verify preclosure requirements and to demonstrate safe and reliable MGR operation; and performance confirmation modeling, testing, and analysis to verify adherence to postclosure regulatory requirements. Development test activities can be planned and conducted by the appropriate design organization as part of the design process. The scope of this study, therefore, will address only surface development testing activities that will be performed prior to detail design and procurement of the MGR surface waste handling equipment. Testing to support development of additional MGR surface equipment and operations, such as cooling of shipping casks and dual-purpose canisters (DPCs) prior to pool entry, decontamination of disposal containers (DCs), and recovery systems for various equipment, is not addressed in this study. These equipment items/systems were not developed for VA and are not currently identified as specific MGR surface waste handling equipment.

Development of controller strategies for a robotized filament winding equipment  

NASA Astrophysics Data System (ADS)

The composites reinforced with continuous fibers of polymeric material are increasingly used in applications where it is essential to reduce weight, mainly due to their high ratio of strength/weight and rigidity/weight. A conventional application are pressure vessels, used for storing liquids or gases subjected to low or high pressure, where the tape continuous fiber-reinforced polymeric matrix material is wound around a mandrel defining the final geometry. In this context the filament winding process is a very attractive process for the production of composite components. For optimal structural performance, and greater weight saving, an optimal path should be adopted, resulting only in axial tension in the longitudinal direction (slip). Such path is the geodesic winding and diverse equipment may be used to guarantee the process automation of the winding. This work herein presented is focused on the study and development of the controller program for a robotized filament winding equipment, taking into account customization of possible trajectories controlling filament winding. The automation of the custom path according to user needs increases exponentially the capabilities, where the use of a robotized solution increases process flexibility and repeatability.

Neurological disorders in essential thrombocythemia  

PubMed Central

Patients with essential thrombocythemia often complain of various subjective neurological symptoms. This prospective study aims to assess their incidence and response to therapy. Among 37 consecutive patients with essential thrombocythemia, 11 presented with neurological symptoms. Among them 4 had thrombotic events, 7 complained of transient or fluctuating subjective symptoms, and one had both. Brain magnetic resonance imagery failed to detect any substratum in patients with subjective symptoms. JAK2V617F mutation was found in 9 of 11 patients with neurological symptoms versus 14 of 26 patients without symptoms. Ten patients received low-dose aspirin for these symptoms: complete resolution was observed in 3, improvement with persisting episodes in 2, and resistance to aspirin in 2 patients, in whom addition of cytoreductive therapy became necessary to resolve those disabling symptoms. In this prospective cohort, 30% of patients with essential thrombocythemia presented neurological symptoms. Aspirin was fully efficient in only 30% of cases. JAK2V617F mutation could be a risk factor for such symptoms.

Experimental Study on the Performance of Quenching Mesh for an Equipment Protection during a Hydrogen Combustion  

SciTech Connect

An igniter has been used as one of the important tools for the control of the hydrogen concentration in the containment. However, the hydrogen control method using an igniter is accompanied essentially with a combustion, which may result in damaging the equipment that should be operated during/after severe accidents. In this paper, an equipment protection test during a hydrogen combustion was carried out using a quenching mesh which is a kind of flame arrester. The temperatures at the surface of the model equipment were measured during the hydrogen combustion when the quenching mesh with about a 0.3 mm gap distance surrounded the model equipment. The effects of the initial pressure and the flame velocity were investigated. The surface temperatures of the model equipment were increased with the initial pressure rise for a 10% hydrogen concentration. The flame velocity with 25 m/s had not an effect on the increase of the surface temperatures of the model equipment for a 9% hydrogen concentration. (authors)

Airway equipment in Scottish emergency departments.  

PubMed

Airway management is the cornerstone of resuscitation. Emergency endotracheal intubation is more likely to be difficult in the accident and emergency (A&E) department setting compared with the operating room. A&E departments must have an appropriate selection of equipment to deal with difficult airway problems. The aim of this study was to determine the type and range of equipment for airway management in A&E departments in Scotland, UK. A two-page postal survey was sent to consultants in charge of 24 A&E departments covering 98% of major trauma patients in Scotland. The response rate was 96% (23/24). Every department had equipment for basic airway management and all had laryngoscopes, stylets, gum elastic bougies and capnography. Ninety-six per cent (22/23) had equipment for performing a surgical airway and 74% (17/23) possessed laryngeal mask airways suitable for adults; only one department did not possess a suitable rescue device. Thirty per cent (7/23) of departments did not use capnography routinely to confirm correct placement of endotracheal tubes. It is concluded that airway equipment in Scottish A&E departments is adequate for basic airway care and endotracheal intubation. Nearly all departments have access to a suitable rescue device for the failed or difficult airway. Capnographic confirmation of tube placement should be mandatory in A&E. PMID:12637855

MHD stability of tokamak plasmas  

SciTech Connect

This paper will give an overview of the some of the methods which are used to simulate the ideal MHD properties of tokamak plasmas. A great deal of the research in this field is necessarily numerical and the substantial progress made during the past several years has roughly paralleled the continuing availability of more advanced supercomputers. These have become essential to accurately model the complex configurations necessary for achieving MHD stable reactor grade conditions. Appropriate tokamak MHD equilibria will be described. Then the stability properties is discussed in some detail, emphasizing the difficulties of obtaining stable high {beta} discharges in plasmas in which the current is mainly ohmically driven and thus demonstrating the need for tailoring the current and pressure profiles of the plasma away from the ohmic state. The outline of this paper will roughly follow the physics development to attain the second region of stability in the PBX-M device at The Princeton Plasmas Physics Laboratory.

Physical security equipment for combating terrorism  

NASA Astrophysics Data System (ADS)

The objective of the Department of Defense Physical Security Equipment (DoD PSE) RDT&E program is to provide end users within the four Services with the most efficient and productive physical security (PS) at the most reasonable cost to ensure the effective protection of DoD resources. These resources include personnel, nuclear weapons, classified information, materiel, and readiness assets. As a result of the1996 Khobar Towers terrorist bombing incident, the DoD PSE program began to receive additional funding in 1997 for Force Protection Commercial-Off-The-Shelf (FP COTS) equipment evaluation and testing. The FP COTS testing applies to all available technologies, which are considered effective for DoD use. Successive terrorist incidents occurring since Khobar Towers have resulted in increasing focus on the demonstration and validation of equipment necessary to combat the ubiquitously asymmetric terrorist threat.

LESSONS LEARNED IN TESTING OF SAFEGUARDS EQUIPMENT.  

SciTech Connect

The International Atomic Energy Agency's (IAEA) Department of Safeguards uses complex instrumentation for the application of safeguards at nuclear facilities around the world. Often, this equipment is developed through cooperation with member state support programs because the Agency's requirements are unique and are not met by commercially available equipment. Before approving an instrument or system for routine inspection use, the IAEA subjects it to a series of tests designed to evaluate its reliability. In 2000, the IAEA began to observe operational failures in digital surveillance systems. In response to the observed failures, the IAEA worked with the equipment designer and manufacturer to determine the cause of failure. An action plan was developed to correct the performance issues and further test the systems to make sure that additional operational issues would not surface later. This paper addresses the steps taken to address operation issues related to digital image surveillance systems and the lessons learned during this process.

Low vision often results in impairment of daily activities, loss of independence, increased risk of fractures, excess health care expense, and reduced physical functioning, quality of life, and life expectancy. Vision rehabilitation can enable more independent functioning for individuals with low vision. The Centers for Medicare and Medicaid Services recognizes the importance of rehabilitation for achieving medically necessary goals but has denied Medicare coverage for vision assistive equipment that is necessary to complete these goals, although they provide coverage for assistive equipment to provide compensation for other disabilities. We believe that this is discriminatory and does not comport with congressional intent. The Centers for Medicare and Medicaid Services should provide coverage for vision assistive equipment, allowing beneficiaries with vision loss to benefit fully from Medicare-covered rehabilitation to achieve the cost-effective results of these services.

Equipment Choices at Connecticut College's Olin Observatory  

NASA Astrophysics Data System (ADS)

In a small college environment where money, time, astronomers and technical support personnel are in short supply, the choice of observatory instrumentation is further constrained by the needs of research topics accessible to undergraduates and by the observatory's local environment. This talk will begin by reviewing the equipment first selected for Connecticut College Olin Observatory to co-exist with these criteria, and how well it met our needs for astronomical undergraduate research and training. The equipment that is now being considered/installed for the next generation of work at this facility will then be discussed.

PCB equipment, operations, and management reference manual  

SciTech Connect

Organizational support and personnel assignment are major factors in managing polychlorinated biphenyl (PCB) contamination of electrical equipment. This requires a recordkeeping and reporting system to keep all parties informed and to assist with decision making. The manual outlines the management tools and procedures for planning a response to PCB spills and managing the transport, storage, and disposal of contaminated equipment. It also describes the health and safety aspects, and analyzes the economics of PCB management. Three appendices define terms and present PCB regulations and occupational-exposure guidelines. 17 figures, 14 tables. (DCK)

Singer HVAC users hit equipment, service  

SciTech Connect

Users report in a survey of heating, ventilating, and air-conditioning (HVAC) systems that they found that Singer's packaged Climate Control rooftop systems are unreliable and the company's service is poor. Respondents ranked Singer 9th in a field of 10 in the survey. Company spokesmen deny the charges, although they acknowledge some distribution problems, and are still marketing the equipment that was criticized. Climate Control users report an inordinate number of maintenance problems and equipment failures, which they blame on poor basic construction and poor-quality parts. (DCK)

Measuring and Test Equipment through barcode technology  

SciTech Connect

Over the past several years, the use, trace methodology, and documentation of Measuring and Test Equipment has become a major concern. Current regulations are forcing companies to develop new policies, providing use history and traceability of Measuring and Test Equipment. The US Department of Energy and Environmental Organizations are driving Westinghouse Hanford Company to comply with the more stringent environmental guidelines and recent modifications in Department of Energy Orders. This paper discusses how the Fast Flux Test Facility at Westinghouse Hanford Company overcame these obstacles by using a computerized system through barcode technology.

Genetic mouse models of essential tremor: are they essential?  

PubMed

The causative genes for essential tremor (ET), one of the most common genetic neurological disorders, have eluded scientists despite intensive search. Two gene loci linked to ET, one on chromosome 3q13 and another on chromosome 2p24.1, have been identified, and a missense mutation in the HS1-BP3 gene on the 2p has been suggested as the cause of the disorder in about 10% of American ET patients. Therefore, the genetic basis for the vast majority of familial ET is still unknown. In this issue of the JCI, the gene coding for the gamma-aminobutyric acidA (GABA(A)) receptor alpha1 subunit is suggested as a potential candidate gene for ET, as mice lacking the gene express a phenotype that overlaps with some clinical characteristics of the human condition.

Stability of large offensive force reductions  

SciTech Connect

The effect of decreasing offensive forces with fixed defenses is much like that of increasing defenses with fixed offenses as studied in Crisis Stability.'' Both increase stability. Even moderate boost-phase defenses strongly attrit first-strike missiles. Preferential attrition by downstream interceptors reduces missile strikes on value is larger with defenses than without, because of the increased survivability of non-alert aircraft. Without defenses the fraction of the defender's Inter-Continental Ballistic Missiles (ICBMs) that survive the first strike is essentially zero. With defenses the number that survive and penetrate boost-phase defenses is significant, but the number that penetrate the preferential defenses downstream rapidly falls to zero. Without defenses the second-strike aircraft are limited to alert aircraft. With defenses the number is essentially the full number of aircraft, which is much larger. Without defenses the total restrike is the sum of missiles and alert aircraft; with defenses it is all of the aircraft. The cost for striking first without defenses differs, but other strike costs are clustered. With defenses the stability index rapidly goes to unity; without them the stability index remains lower throughout. With defenses, the expected number of missile weapons on value drops rapidly to zero; without defenses it remains high to low levels of offensive forces. This pattern holds for various combinations of defenses and attacks. Without defenses, offensive reductions could lead to large reductions in stability; with defenses, large reductions would increase stability. 3 refs.
