Test results: Halon 1301 versus water sprinkler fire protection for essential electronic equipment  

NASA Astrophysics Data System (ADS)

This report describes results of testing two contending extinguishants, Halon 1301 and water, for fire protection of essential electronic equipment. A series of controlled fires in a facility housing an operational electronic data processing system sought to establish immediate and long term effects of exposure of sensitive electronic equipment and stored data to fire extinguishment atmospheres. Test results lead to the conclusion that Halon 1301 is superior to water as an extinguishant for fires occurring in essential electronic equipment installations.

Essentials of Airway Management, Oxygenation, and Ventilation: Part 1: Basic Equipment and Devices  

PubMed Central

Offices and outpatient dental facilities must be properly equipped with devices for airway management, oxygenation, and ventilation. Optimizing patient safety using crisis resource management (CRM) involves the entire dental office team being familiar with airway rescue equipment. Basic equipment for oxygenation, ventilation, and airway management is mandated in the majority of US dental offices per state regulations. The immediate availability of this equipment is especially important during the administration of sedation and anesthesia as well as the treatment of medical urgencies/emergencies. This article reviews basic equipment and devices essential in any dental practice whether providing local anesthesia alone or in combination with procedural sedation. Part 2 of this series will address advanced airway devices, including supraglottic airways and armamentarium for tracheal intubation and invasive airway procedures. PMID:24932982

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.

Essential role of Duox in stabilization of Drosophila wing.  

PubMed

NADPH oxidase produces reactive oxygen species (ROS). Drosophila melanogaster has two homologs of NADPH oxidase, dNox and dDuox, with functions that remain unclear in vivo. To clarify these functions, two independent transgenic fly lines expressing dsRNA targeted for different portions of dDuox mRNA were used. In both flies, en-GAL4> UAS-dDuoxIR(976-1145) and en-GAL4> UAS-dDuoxIR(370-518), in which dDuox was knocked down selectively in the posterior area of the wing disc, the posterior compartment of the adult wings became paler and more fragile with wing veins that were indistinct by comparison with the anterior one. Fluorescence staining of the en-GAL4> UAS-dDuoxIR(976-1145) adult wings revealed that the ROS concentration in the posterior compartment was significantly lower than that in the anterior compartment. Moreover, in these flies, the posterior compartment of the wing imaginal disc showed a greater number of apoptotic cells detected by immunostaining with anti-cleaved caspase-3 antibody than those in the anterior compartment. Respective knockdown of tyrosine hydroxylase or dopa-decarboxylase showed paler wing blades in the posterior compartment similar to the phenotype of dDuox-knockdown files. Along with this observation, analysis of the catecholic and dityrosine components in the wings of adult flies proved that dDuox plays important roles in the stabilization of the cuticle structure of the wings via tyrosine cross-linking, the sclerotization and melanization processes possibly through ROS production. These dDuox-knockdown fly lines would be useful tools for further studying dDuox functions during the development of Drosophila. PMID:21808060

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

Stability of the Martian atmosphere: Is heterogeneous catalysis essential?  

NASA Technical Reports Server (NTRS)

A comprehensive homogeneous gas phase photochemical model is developed to study the problem of stability of the Martian atmosphere. The one-dimensional model extends from the ground up to 220 km, passing through the homopause at 125 km. The model thus couples the lower (neutral) atmosphere to the ionosphere above which provides significant downward flux of carbon monoxide and oxygen atoms. It is concluded on the basic of currently accepted values for globally and seasonally averaged water vapor abundance, dust opacity and the middle atmospheric eddy mixing coefficient, as well as the relevant laboratory data (particularly the temperature dependence of CO2 absorption cross section and the rate constant for CO+OH reaction), that the rate of re-formation of carbon dioxide exceeds its photolytic destruction rate by about 40%. Furthermore, it is found that this result is virtually independent of the choice of eddy mixing coefficient, unless its value in the middle atmosphere exceeds 10(exp 8) sq cm/sec or is far smaller than 10(exp 5)sq cm/sec, or the dust opacity, unless it exceeds unity, or the water vapor mixing ratio at the surface, unless it is far smaller (less than or = 1 ppm) or far greater (greater than or = 500 ppm) than the average value (approximately 150 ppm). Since none of these extremes represent globally and seasonally averaged conditions on Mars, we propose that the present model requires existence of a mechanism to throttle down the recycling rate of carbon dioxide on Mars. Therefore, it is suggested that a heterogeneous process which provides a sink to the species that participate in the recycling of CO2, i.e., H2O, H2O2, OH, CO or O, in particular, may be necessary to bring about the balance between the CO2 recycling rate and its photolytic destruction rate. Aerosols of dust or ice (pure or doped water or carbon dioxide ice present in the atmosphere of Mars) can provide the appropriate adsorption sites for the above heterogeneous process. Despite our conclusion that some heterogeneous process may be needed, it is important to recognize that one-dimensional models can only provide first-order results which, most likely, represent globally and seasonally averaged conditions. However, it is only after actual temporal, latitudinal and longitudinal variations of relevant atmospheric parameters are included in the model that one can determine fuly whether the problem of atmospheric stabiltiy still continues to persist and whether some heterogeneous process is required to correct it.

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.

The essentials of the Kerr effect for polymer-stabilized blue phase liquid crystal  

NASA Astrophysics Data System (ADS)

The essentials of the Kerr effect of the polymer-stabilized blue phase liquid crystal (PS-BPLC) are examined using the director model. The Kerr effect describes that the induced birefringence is proportional to the square of the magnitude of the electric field E. The formula should be corrected when E is large. In contrast, the director model can describe the induced birefringence for any magnitude of E. From the director model, it can be found that the birefringence value essentially has a linear relationship with the averaged direction cosine of the directors with respect to the direction of the electric field.

Thermal and oxidative stability of the Ocimum basilicum L. essential oil/?-cyclodextrin supramolecular system  

PubMed Central

Summary Ocimum basilicum L. essential oil and its ?-cyclodextrin (?-CD) complex have been investigated with respect to their stability against the degradative action of air/oxygen and temperature. This supramolecular system was obtained by a crystallization method in order to achieve the equilibrium of complexed–uncomplexed volatile compounds in an ethanol/water solution at 50 °C. Both the raw essential oil and its ?-CD complex have been subjected to thermal and oxidative degradation conditions in order to evaluate the protective capacity of ?-CD. The relative concentration of the O. basilicum L. essential oil compounds, as determined by GC–MS, varies accordingly with their sensitivity to the thermal and/or oxidative degradation conditions imposed. Furthermore, the relative concentration of the volatile O. basilicum L. compounds found in the ?-CD complex is quite different in comparison with the raw material. An increase of the relative concentration of linalool oxide from 0.3% to 1.1%, in addition to many sesquiterpene oxides, has been observed. ?-CD complexation of the O. basilicum essential oil modifies the relative concentration of the encapsulated volatile compounds. Thus, linalool was better encapsulated in ?-CD, while methylchavicol (estragole) was encapsulated in ?-CD at a concentration close to that of the raw essential oil. Higher relative concentrations from the degradation of the oxygenated compounds such as linalool oxide and aromadendren oxide were determined in the raw O. basilicum L. essential oil in comparison with the corresponding ?-CD complex. For the first time, the protective capability of natural ?-CD for labile basil essential oil compounds has been demonstrated. PMID:25550747

Sde2: A novel nuclear protein essential for telomeric silencing and genomic stability in Schizosaccharomyces pombe  

SciTech Connect

Research highlights: {yields} Sde2 is essential for telomere silencing. {yields} Sde2 is involved in the maintenance of genomic stability. {yields} Sde2 promotes the recruitment of SHREC, a histone deacetylase complex, to telomeres. -- Abstract: Telomeres, specialized domains assembled at the ends of linear chromosomes, are essential for genomic stability in eukaryotes. The formation and maintenance of telomeres are governed by numerous factors such as telomeric repeats, telomere-binding proteins, heterochromatin proteins, and telomerase. Here, we report Sde2, a novel nuclear protein essential for telomeric silencing and genomic stability in the fission yeast Schizosaccharomyces pombe. A deficiency in sde2 results in the derepression of the ura4{sup +} gene inserted near telomeric repeats, and the noncoding transcripts from telomeric regions accumulate in sde2{Delta} cells. The loss of Sde2 function compromises transcriptional silencing at telomeres, and this silencing defect is accompanied by increased levels of acetylated histone H3K14 and RNA polymerase II occupancy at telomeres as well as reduced recruitment of the SNF2 ATPase/histone deacetylase-containing complex SHREC to telomeres. Deletion of sde2 also leads to a higher frequency of mitotic minichromosome loss, and sde2{Delta} cells often form asci that contain spores in abnormal numbers, shapes, or both. In addition, sde2{Delta} cells are highly sensitive to several stresses, including high/low temperatures, bleomycin, which induces DNA damage, and thiabendazole, a microtubule-destabilizing agent. Furthermore, Sde2 genetically interacts with the telomere regulators Taz1, Pof3, and Ccq1. These findings demonstrate that Sde2 cooperates with other telomere regulators to maintain functional telomeres, thereby preventing genomic instability.

Effect of downhole assembly and cutter geometry on stability of drillstrings equipped with polycrystalline diamond compact (PDC) cutters  

SciTech Connect

Stability of drillstrings equipped with PDC cutters depends on many factors such as the design of the drillstring, design of the cutter, and formation type. In this paper, the authors show that the drill pipe plays a minor role in stability in comparison with that of the drill collars. They also show that the number of cutter blades affects the location of the stability pockets, while their spacing affects the size of these pockets. Using this data, a combination of drill collar and cutter design can be used to provide operating speeds resulting in maximum stability of the drillstring.

GIT1 and ?PIX are essential for GABA(A) receptor synaptic stability and inhibitory neurotransmission.  

PubMed

Effective inhibitory synaptic transmission requires efficient stabilization of GABA(A) receptors (GABA(A)Rs) at synapses, which is essential for maintaining the correct excitatory-inhibitory balance in the brain. However, the signaling mechanisms that locally regulate synaptic GABA(A)R membrane dynamics remain poorly understood. Using a combination of molecular, imaging, and electrophysiological approaches, we delineate a GIT1/?PIX/Rac1/PAK signaling pathway that modulates F-actin and is important for maintaining surface GABA(A)R levels, inhibitory synapse integrity, and synapse strength. We show that GIT1 and ?PIX are required for synaptic GABA(A)R surface stability through the activity of the GTPase Rac1 and downstream effector PAK. Manipulating this pathway using RNAi, dominant-negative and pharmacological approaches leads to a disruption of GABA(A)R clustering and decrease in the strength of synaptic inhibition. Thus, the GIT1/?PIX/Rac1/PAK pathway plays a crucial role in regulating GABA(A)R synaptic stability and hence inhibitory synaptic transmission with important implications for inhibitory plasticity and information processing in the brain.

Hdac3 is essential for the maintenance of chromatin structure and genome stability  

PubMed Central

Summary Hdac3 is essential for efficient DNA replication and DNA damage control. Deletion of Hdac3 impaired DNA repair and greatly reduced chromatin compaction and heterochromatin content. These defects corresponded to increases in histone H3K9,K14ac, and H4K5ac and H4K12ac in late S phase of the cell cycle, and histone deposition marks were retained in quiescent Hdac3-null cells. Liver-specific deletion of Hdac3 culminated in hepatocellular carcinoma. While HDAC3 expression was down regulated in only a small number of human liver cancers, the mRNA levels of the HDAC3 cofactor NCOR1 were reduced in 1/3 of these cases. siRNA targeting of NCOR1 and SMRT (NCOR2) increased H4K5ac and caused DNA damage, indicating that the HDAC3/NCOR/SMRT axis is critical for maintaining chromatin structure and genomic stability.

Dimerization is essential for 14-3-3zeta stability and function in vivo.  

PubMed

Members of the conserved 14-3-3 protein family spontaneously self-assemble as homo- and heterodimers via conserved sequences in the first four (alphaA-alphaD) of the nine helices that comprise them. Dimeric 14-3-3s bind conserved motifs in diverse protein targets involved in multiple essential cellular processes including signaling, intracellular trafficking, cell cycle regulation, and modulation of enzymatic activities. However, recent mostly in vitro evidence has emerged, suggesting functional and regulatory roles for monomeric 14-3-3s. We capitalized on the simplicity of the 14-3-3 family in Drosophila to investigate in vivo 14-3-3zeta monomer properties and functionality. We report that dimerization is essential for the stability and function of 14-3-3zeta in neurons. Moreover, we reveal the contribution of conserved amino acids in helices A and D to homo- and heterodimerization and their functional consequences on the viability of animals devoid of endogenous 14-3-3zeta. Finally, we present evidence suggesting endogenous homeostatic adjustment of the levels of the second family member in Drosophila, D14-3-3epsilon, to transgenic monomeric and dimerization-competent 14-3-3zeta.

Dishevelled stabilization by the ciliopathy protein Rpgrip1l is essential for planar cell polarity  

PubMed Central

Cilia are at the core of planar polarity cellular events in many systems. However, the molecular mechanisms by which they influence the polarization process are unclear. Here, we identify the function of the ciliopathy protein Rpgrip1l in planar polarity. In the mouse cochlea and in the zebrafish floor plate, Rpgrip1l was required for positioning the basal body along the planar polarity axis. Rpgrip1l was also essential for stabilizing dishevelled at the cilium base in the zebrafish floor plate and in mammalian renal cells. In rescue experiments, we showed that in the zebrafish floor plate the function of Rpgrip1l in planar polarity was mediated by dishevelled stabilization. In cultured cells, Rpgrip1l participated in a complex with inversin and nephrocystin-4, two ciliopathy proteins known to target dishevelled to the proteasome, and, in this complex, Rpgrip1l prevented dishevelled degradation. We thus uncover a ciliopathy protein complex that finely tunes dishevelled levels, thereby modulating planar cell polarity processes. PMID:22927466

Stabilization of sunflower oil with Carum copticum Benth & Hook essential oil.  

PubMed

In this study, application of various concentrations (0.025%, 0.05% and 0.075%) of Carum copticum essential oil (EO) were examined on oxidative stability of sunflower oil and there were compared to Butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) during storage at 37 and 47 °C. The main compounds of EO were identified as thymol (50.07%), ?- terpinene (23.92%) and p-cymene (22.9%). Peroxide value (PV), anisidine value (AnV) and thiobarbituric acid (TBA) value measurement in sunflower oil showed that all concentrations of EO had antioxidant effect in comparison to BHA and BHT. Samples added with EO at 0.075% were the most stable during storage at both temperatures (P?stabilization factor (F) and antioxidant power (AOP) determination confirmed efficacy of this EO as antioxidant in sunflower oil. EO also was able to reduce the stable free radical 2, 2-diphenyl-1-picrylhydrazyl (DPPH) with a 50% inhibition concentration (IC50) of 20.3?±?0.9 ?g/mL. Therefore, the results indicate that EO could be used as a natural antioxidant in food lipids. PMID:24426060

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

Evaluation of thermal-oxidative stability and antiglioma activity of Zanthoxylum tingoassuiba essential oil entrapped into multi- and unilamellar liposomes.  

PubMed

Zanthoxylum tinguassuiba essential oil (ZtEO) contains ?-bisabolol, a known antiglioma sesquiterpene, among other potentially active substances. Medical applications of this essential oil require advances in the design of distinctive carriers due to its low water solubility and easy degradation by heat, light, and oxygen. The aim of this work was to evaluate enhancement in oxidative stability and the ability to reduce glioblastoma cell viability of ZtEO loaded into liposomes. Multi- and unilamellar vesicles were prepared to carry ZtEO. By using thermal analysis, it was observed that thermal-oxidative stability of the liposomal ZtEO was enhanced, when compared to its free form. Liposomal ZtEO also presented significant apoptotic-inducing activity for glioma cells. These results show that liposomal systems carrying ZtEO may be a potential alternative for gliobastoma treatment. PMID:21548711

We have developed an interferometer for gauge block calibration based on phase shifting evaluation. The measurement process can provide flatness, parallelism and longitude. The employed wavelengths need to be corrected according to the refractive index of the air the light beams passes through. In our case, this correction is obtained indirectly using readings of temperature, pressure and relative humidity taken by high resolution sensors. To preserve stability, the interferometer is encapsulated in a chamber with active temperature control. The design, measurement principle, calibration, stability and reproducibility are analyzed. Since one of our goals is to employ robust and cheap diode lasers as light sources, this paper describes also the system we are developing to carry out a red diode laser stabilization using a mode locking technique. The instruments and assembly employed to avoid the Doppler effect in the gas cells, which limit wavelength resolution, are described as well. Several experimental tests have been carried out that show the great susceptibility of this assembly to changes in environmental conditions, which affect the iodine cell's absorption spectrum.

The high molecular weight neurofilament subunit plays an essential role in axonal outgrowth and stabilization  

PubMed Central

ABSTRACT Neurofilaments (NFs) are thought to provide structural support to mature axons via crosslinking of cytoskeletal elements mediated by the C-terminal region of the high molecular weight NF subunit (NF-H). Herein, we inhibited NF-H expression in differentiating mouse NB2a/d1 cells with shRNA directed against murine NF-H without affecting other NF subunits, microtubules or actin. shRNA-mediated NF-H knockdown not only in compromised of late-stage axonal neurite stabilization but also compromised early stages of axonal neurite elongation. Expression of exogenous rat NF-H was able to compensate for knockdown of endogenous NF-H and restored the development and stabilization of axonal neurites. This rescue was prevented by simultaneous treatment with shRNA that inhibited both rat and murine NF-H, or by expression of exogenous rat NF-H lacking the C-terminal sidearm during knockdown of endogenous NF-H. Demonstration of a role for NF-H in the early stages of axonal elaboration suggests that axonal stabilization is not delayed until synaptogenesis, but rather that the developing axon undergoes sequential NF-H-mediated stabilization along its length in a proximal–distal manner, which supports continued pathfinding in distal, unstabilized regions.

Tensin-4-dependent MET stabilization is essential for survival and proliferation in carcinoma cells.  

PubMed

Inappropriate MET tyrosine kinase receptor signaling is detected in almost all types of human cancer and contributes to malignant growth and MET dependency via proliferative and antiapoptotic activities. Independently, Tensin-4 (TNS4) is emerging as a putative oncogene in many cancer types, but the mechanisms of TNS4 oncogenic activity are not well established. Here, we demonstrate that TNS4 directly interacts with phosphorylated MET via the TNS4 SH2-domain to positively regulate cell survival, proliferation, and migration, through increased MET protein stability. In addition, TNS4 interaction with ?1-integrin cytoplasmic tail positively regulates ?1-integrin stability. Loss of TNS4 or disruption of MET-TNS4 interaction triggers MET trafficking toward the lysosomal compartment that is associated with excessive degradation of MET and triggers MET-addicted carcinoma cell death in vitro and in vivo. Significant correlation between MET and TNS4 expression in human colon carcinoma and ovarian carcinoma suggests TNS4 plays a critical role in MET stability in cancer. PMID:24814316

CHL-1 provides an essential function affecting cell proliferation and chromosome stability in Caenorhabditis elegans.  

PubMed

A family of helicases that are important in maintaining genome stability is the iron-sulfur group. Members of this family include DOG-1/FANCJ, RTEL1, XPD and Chl1p/DDX11. In Caenorhabitis elegans, the predicted gene M03C11.2 has orthology to the CHL1 (Chromosome loss 1) gene in Saccharomyces cerevisiae and DDX11 (DEAD/H box polypeptide 11) in humans. In this paper, we show that the chl-1 gene in C. elegans is required for normal development and fertility. Mutants have lineage-independent cell proliferation defects that result in a Stu (sterile uncoordinated) phenotype, characterized by gonadal abnormalities and a reduced number of D motor neurons and seam cells. A chromosome stability defect is present in the germ cells, where an abnormal number of DAPI-staining chromosomes appear in diakinesis. CHL-1 function is required for the integrity of poly-guanine/poly-cytosine DNA in the absence of DOG-1/FANCJ: the loss of CHL-1 alone does not result in the deletion of G-tracts, but it does increase the number of deletions observed in the dog-1; chl-1 double mutant, indicating a role for CHL-1 during replication and repair. In addition, we observed that cohesin defects increased the number of deletions in the absence of DOG-1/FANCJ. Our results demonstrate a role for CHL-1 in cell proliferation and maintaining normal chromosome numbers, and implicate CHL-1 in chromosome stability and repair of unresolved secondary structures during replication.

[RTEL1 (regulator of telomere elongation helicase 1), a DNA helicase essential for genome stability].  

PubMed

RTEL1 (regulator of telomere length helicase 1) is a DNA helicase that has been identified more than 10 years ago. Many works since, mainly in the nematode Caenorhabditis elegans and the mouse, have highlighted its role in chromosomal stability, maintenance of telomere length, and DNA repair. Recently, four laboratories have characterized RTEL1 mutations in patients with dyskeratosis congenita (DC) and Hoyeraal-Hreidarsson (HH) syndrome, a rare and severe variant of DC. We here summarize the current knowledge on RTEL1 and discuss the possible other functions that RTEL1 could play. PMID:24356145

Enhancing stability of essential oils by microencapsulation for preservation of button mushroom during postharvest.  

PubMed

Fresh button mushrooms (Agaricus bisporus L.) are sensitive to browning, water loss, and microbial attack. The short shelf-life of mushrooms is an impediment to the distribution and marketing of the fresh product. Essential oils outstand as an alternative to chemical preservatives and their use in foods meets the demands of consumers for natural products. To resolve controlled release of oil and increase in antioxidant and antimicrobial activities, the oil was incorporated into microcapsules. Effects of microcapsulated thyme (Thymus vulgaris L.) and rosemary (Rosmarinus officinalis L.) on quality of fresh button mushroom were compared. Physicochemical qualities were evaluated during 15 days of storage at 4 ± 0.5°C. All treatments prevented product weight loss and decrease in polyphenoloxidase and peroxidase activities during storage. Color and firmness, microbiological analysis, and total phenolic content caused the least change. With use of microencapsulated oils, mushrooms were within acceptable limits during 10 days of storage. Microencapsulated rosemary oil produced the highest beneficial effects and has potential to improve quality of button mushrooms and extend shelf-life. PMID:25473510

Retinoic Acid is essential for Th1 cell lineage stability and prevents transition to a th17 cell program.  

PubMed

CD4(+) T cells differentiate into phenotypically distinct T helper cells upon antigenic stimulation. Regulation of plasticity between these CD4(+) T-cell lineages is critical for immune homeostasis and prevention of autoimmune disease. However, the factors that regulate lineage stability are largely unknown. Here we investigate a role for retinoic acid (RA) in the regulation of lineage stability using T helper 1 (Th1) cells, traditionally considered the most phenotypically stable Th subset. We found that RA, through its receptor RAR?, sustains stable expression of Th1 lineage specifying genes, as well as repressing genes that instruct Th17-cell fate. RA signaling is essential for limiting Th1-cell conversion into Th17 effectors and for preventing pathogenic Th17 responses in vivo. Our study identifies RA-RAR? as a key component of the regulatory network governing maintenance and plasticity of Th1-cell fate and defines an additional pathway for the development of Th17 cells.

Stability of essential drugs in the field: results of a study conducted over a two-year period in Burkina Faso.  

PubMed

To evaluate the stability of essential drugs stored in realistic tropical conditions, we have carried out a two-year prospective study in western Burkina Faso. Twenty-seven essential drugs were stored in a rural site and a urban one where temperature and hygrometry were recorded daily. Samples of each drug were taken for further analysis to the World Health Organization Collaborative Center for the Study of Stability of Drugs in Nantes, France every three months. Quantitative analysis showed that the majority of samples suffered no significant loss of their active ingredient. In contrast, ampicillin, erythromycin, sulfaguanidine, injectable furosemide, penicillin G, trimethoprim, and chloroquine showed more than a 10% quantitative loss of their active ingredient. Thus, it is not recommended that these essential drugs be stored for more than one year in a tropical climate. PMID:9242314

Phytophthora infestans effector AVR3a is essential for virulence and manipulates plant immunity by stabilizing host E3 ligase CMPG1  

PubMed Central

Fungal and oomycete plant pathogens translocate effector proteins into host cells to establish infection. However, virulence targets and modes of action of their effectors are unknown. Effector AVR3a from potato blight pathogen Phytophthora infestans is translocated into host cells and occurs in two forms: AVR3aKI, which is detected by potato resistance protein R3a, strongly suppresses infestin 1 (INF1)-triggered cell death (ICD), whereas AVR3aEM, which evades recognition by R3a, weakly suppresses host ICD. Here we show that AVR3a interacts with and stabilizes host U-box E3 ligase CMPG1, which is required for ICD. In contrast, AVR3aKI/Y147del, a mutant with a deleted C-terminal tyrosine residue that fails to suppress ICD, cannot interact with or stabilize CMPG1. CMPG1 is stabilized by the inhibitors MG132 and epoxomicin, indicating that it is degraded by the 26S proteasome. CMPG1 is degraded during ICD. However, it is stabilized by mutations in the U-box that prevent its E3 ligase activity. In stabilizing CMPG1, AVR3a thus modifies its normal activity. Remarkably, given the potential for hundreds of effector genes in the P. infestans genome, silencing Avr3a compromises P. infestans pathogenicity, suggesting that AVR3a is essential for virulence. Interestingly, Avr3a silencing can be complemented by in planta expression of Avr3aKI or Avr3aEM but not the Avr3aKI/Y147del mutant. Our data provide genetic evidence that AVR3a is an essential virulence factor that targets and stabilizes the plant E3 ligase CMPG1, potentially to prevent host cell death during the biotrophic phase of infection.

Experimental Verification of the Rudder-Free Stability Theory for an Airplane Model Equipped with Rudders Having Negative Floating Tendency and Negligible Friction  

NASA Technical Reports Server (NTRS)

An investigation has been made in the Langley free-flight tunnel to obtain an experimental verification of the theoretical rudder-free stability characteristics of an airplane model equipped with conventional rudders having negative floating tendencies and negligible friction. The model used in the tests was equipped with a conventional single vertical tail having rudder area 40 percent of the vertical tail area. The model was tested both in free flight and mounted on a strut that allowed freedom only in yaw. Tests were made with three different amounts of rudder aerodynamic balance and with various values of mass, moment of inertia, and center-of-gravity location of the rudder. Most of the stability derivatives required for the theoretical calculations were determined from forced and free-oscillation tests of the particular model tested. The theoretical analysis showed that the rudder-free motions of an airplane consist largely of two oscillatory modes - a long-period oscillation somewhat similar to the normal rudder-fixed oscillation and a short-period oscillation introduced only when the rudder is set free. It was found possible in the tests to create lateral instability of the rudder-free short-period mode by large values of rudder mass parameters even though the rudder-fixed condition was highly stable. The results of the tests and calculation indicated that for most present-day airplanes having rudders of negative floating tendency, the rudder-free stability characteristics may be examined by simply considering the dynamic lateral stability using the value of the directional-stability parameter Cn(sub p) for the rudder-free condition in the conventional controls-fixed lateral-stability equations. For very large airplanes having relatively high values of the rudder mass parameters with respect to the rudder aerodynamic parameters, however, analysis of the rudder-free stability should be made with the complete equations of motion. Good agreement between calculated and measured rudder-free stability characteristics was obtained by use of the general rudder-free stability theory, in which four degrees of lateral freedom are considered. When this assumption is made that the rolling motions alone or the lateral and rolling motions may be neglected in the calculations of rudder-free stability, it is possible to predict satisfactorily the characteristics of the long-period (Dutch roll type) rudder-free oscillation for airplanes only when the effective-dihedral angle is small. With these simplifying assumptions, however, satisfactory prediction of the short-period oscillation may be obtained for any dihedral. Further simplification of the theory based on the assumption that the rudder moment of inertia might be disregarded was found to be invalid because this assumption made it impossible to calculate the characteristics of the short-period oscillations.

The Influence of Process Equipment on the Properties of Suspension Plasma Sprayed Yttria-Stabilized Zirconia Coatings  

NASA Astrophysics Data System (ADS)

Suspension plasma-sprayed YSZ coatings were deposited at lab-scale and production-type facilities to investigate the effect of process equipment on coating properties. The target application for these coatings is solid oxide fuel cell (SOFC) electrolytes; hence, dense microstructures with low permeability values were preferred. Both facilities had the same torch but different suspension feeding systems, torch robots, and substrate holders. The lab-scale facility had higher torch-substrate relative speeds compared with the production-type facility. On porous stainless steel substrates, permeabilities and microstructures were comparable for coatings from both facilities, and no segmentation cracks were observed. Coating permeability was further reduced by increasing substrate temperatures during deposition or reducing suspension feed rates. On SOFC cathode substrates, coatings made in the production-type facility had higher permeabilities and more segmentation cracks compared with coatings made in the lab-scale facility. Increased cracking in coatings from the production-type facility was likely caused mainly by its lower torch-substrate relative speed.

Structural Stability of Human Fibroblast Growth Factor-1 Is Essential for Protective Effects Against Radiation-Induced Intestinal Damage  

SciTech Connect

Purpose: Human fibroblast growth factor-1 (FGF1) has radioprotective effects on the intestine, although its structural instability limits its potential for practical use. Several stable FGF1 mutants were created increasing stability in the order, wild-type FGF1, single mutants (Q40P, S47I, and H93G), Q40P/S47I, and Q40P/S47I/H93G. This study evaluated the contribution of the structural stability of FGF1 to its radioprotective effect. Methods and Materials: Each FGF1 mutant was administered intraperitoneally to BALB/c mice in the absence of heparin 24 h before or after total body irradiation (TBI) with {gamma}-rays at 8-12 Gy. Several radioprotective effects were examined in the jejunum. Results: Q40P/S47I/H93G could activate all subtypes of FGF receptors in vitro much more strongly than the wild-type without endogenous or exogenous heparin. Preirradiation treatment with Q40P/S47I/H93G significantly increased crypt survival more than wild-type FGF1 after TBI at 10 or 12 Gy, and postirradiation treatment with Q40P/S47I/H93G was effective in promoting crypt survival after TBI at 10, 11, or 12 Gy. In addition, crypt cell proliferation, crypt depth, and epithelial differentiation were significantly promoted by postirradiation treatment with Q40P/S47I/H93G. The level of stability of FGF1 mutants correlated with their mitogenic activities in vitro in the absence of heparin; however, preirradiation treatment with the mutants increased the crypt number to almost the same level as Q40P/S47I/H93G. When given 24 h after TBI at 10 Gy, all FGF1 mutants increased crypt survival more than wild-type FGF1, and Q40P/S47I/H93G had the strongest mitogenic effects in intestinal epithelial cells after radiation damage. Moreover, Q40P/S47I/H93G prolonged mouse survival after TBI because of the repair of intestinal damage. Conclusion: These findings suggest that the structural stability of FGF1 can contribute to the enhancement of protective effects against radiation-induced intestinal damage. Therefore, Q40P/S47I/H93G is pharmacologically one of the most promising candidates for clinical applications for radiation-induced gastrointestinal syndrome.

Effect of thyme/cumin essential oils and butylated hydroxyl anisole/butylated hydroxyl toluene on physicochemical properties and oxidative/microbial stability of chicken patties.  

PubMed

In this study, effects of thyme/cumin essential oils (EO) and butylated hydroxyl anisole (BHA)/butylated hydroxyl toluene (BHT) on physicochemical properties and storage stability of chicken patties were compared in different storage periods (0, 3, 7, 14, 21, and 28 d). It was found that there were significant (P < 0.05) differences between physicochemical properties of patty samples treated with EO and the synthetic antioxidants. The EO showed similar performance to those of BHA and BHT in limiting TBARS values of chicken patty samples. Similarity in performance was also the case for microbial stability (total aerobic mesophilic, psychrotrophic, lactic acid, and coliform bacteria as well as molds and yeasts); namely, their effects were significant (P < 0.05). Effect of thyme EO was significant (P < 0.05) and remarkable, not allowing any coliform bacteria to grow in the samples. Given that EO were obtained from natural sources, the data suggested that the EO might be more useful than their synthetic counterparts, BHA and BHT, as additives for chicken patties to maintain oxidative/microbial stability and increase shelf life.

Fabrication, stability and efficacy of dual-component antimicrobial nanoemulsions: essential oil (thyme oil) and cationic surfactant (lauric arginate).  

PubMed

The influence of a cationic surfactant (lauric arginate, LAE) on the physical properties and antimicrobial efficacy of thyme oil nanoemulsions was investigated. Nanoemulsions prepared from pure thyme oil were highly unstable due to Ostwald ripening, but they could be stabilized by adding a ripening inhibitor (corn oil) to the oil phase prior to homogenisation. The loading capacity and antimicrobial efficacy of thyme oil nanoemulsions were significantly increased by adding LAE. In the absence of LAE, at least 60 wt% corn oil had to be added to the lipid phase to inhibit Ostwald ripening; but in the presence of 0.1 wt% LAE, only 30 wt% corn oil was needed. LAE addition substantially increased the antimicrobial efficacy of the thyme oil nanoemulsions: 200 ?g/ml thyme oil was needed to inhibit growth of a spoilage yeast (Zygosaccharomyces bailii) if LAE was added, whereas ? 400 ?g/ml was needed in the absence of LAE.

Essential role of the N- and C-terminals of laccase from Pleurotus florida on the laccase activity and stability.  

PubMed

POXA1b is the most thermostable laccase isoenzyme from Pleurotus ostreatus. POXA1b is remarkably stable at alkaline pH (the t1/2 at pH 10 was 30 days), and its C-terminal affects its catalytic and stability properties. We cloned POXA1c from P. florida, which showed 99 % identity with POXA1b. POXA1c was functionally expressed in Pichia pastoris. The functions of the N and C termini of POXA1c were investigated using site-directed mutagenesis. Compared with POXA1c, the N-terminal R5V site effectively increased the specific activities for 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and guaiacol by 2- and 3.5-fold, respectively. A C-terminal truncated mutant, POXA1c?13, also increased the specific activities for ABTS and guaiacol by 2.3- and 3.4-fold, respectively. A double mutant, POXA1c?13-R5V, combined the R5V and ?13 effects. The specific activity of this double mutant for ABTS was 1,321 U/mg, which indicated a 4-fold increase compared with the wild type. The role of residue V5 on laccase catalytic properties was also observed for laccases from Trametes versicolor and Rigidoporus lignosus. The specific activities of the V5R of the laccases from T. versicolor and R. lignosus were half of that of the wild type. The pH and thermal stability analysis of POXA1c and its mutants showed that the enzymes were remarkably stable because they showed 63 % residual activity after incubation for 108 h at 30 °C over a pH range of 4.5 to 9.0. Similar results were observed for POXA1c?13-R5V. POXA1c?13-R5V can be widely used in industrial biotechnology because of its excellent catalytic properties. PMID:25161036

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.

Anti-rancidity effect of essential oils, application in the lipid stability of cooked turkey meat patties and potential implications for health.  

PubMed

Abstract Twenty-three commercial essential oils were tested for their anti-rancidity effect and potential implications to prolong the induction time of corn oil and extend the shelf life of cooked turkey patties. Moreover, the potential health benefit was investigated through DPPH, ABTS, ?-carotene bleaching, FRAP, and ?-amylase inhibitory assays. Essential oils' composition was investigated by GC-MS. Cumin, thyme, clove, and cinnamon oils improved oxidative stability and increased the induction time of the corn oil 1.5-3 fold. Clove and cinnamon oils were particularly effective in delaying lipid oxidation of cooked turkey patties (time of induction 11.04 and 9.43?h) compared with the plain burger (5.04?h). Both oils are also characterized by a potent radical scavenging activity in ABTS test (IC50 values of 1.43 and 2.05??g/ml for cinnamon and clove, respectively). In the ?-amylase inhibitory assay, cumin and grape fruits were the most potent with IC50 values of 21.88 and 23.95 ?g/ml, respectively. PMID:25265207

CK2 phospho-dependent binding of R2TP complex to TEL2 is essential for mTOR and SMG1 stability.  

PubMed

TEL2 interacts with and is essential for the stability of all phosphatidylinositol 3-kinase-related kinases (PIKKs), but its mechanism of action remains unclear. Here, we show that TEL2 is constitutively phosphorylated on conserved serines 487 and 491 by casein kinase 2 (CK2). Proteomic analyses establish that the CK2 phosphosite of TEL2 confers binding to the R2TP/prefoldin-like complex, which possesses chaperon/prefoldin activities required during protein complex assembly. The PIH1D1 subunit of the R2TP complex binds directly to the CK2 phosphosite of TEL2 in vitro and is required for the TEL2-R2TP/prefoldin-like complex interaction in vivo. Although the CK2 phosphosite mutant of TEL2 retains association with the PIKKs and HSP90 in cells, failure to interact with the R2TP/prefoldin-like complex results in instability of the PIKKs, principally mTOR and SMG1. We propose that TEL2 acts as a scaffold to coordinate the activities of R2TP/prefoldin-like and HSP90 chaperone complexes during the assembly of the PIKKs. PMID:20864032

Suitable features selection for monitoring thermal condition of electrical equipment using infrared thermography  

NASA Astrophysics Data System (ADS)

Monitoring the thermal condition of electrical equipment is necessary for maintaining the reliability of electrical system. The degradation of electrical equipment can cause excessive overheating, which can lead to the eventual failure of the equipment. Additionally, failure of equipment requires a lot of maintenance cost, manpower and can also be catastrophic- causing injuries or even deaths. Therefore, the recognition processof equipment conditions as normal and defective is an essential step towards maintaining reliability and stability of the system. The study introduces infrared thermography based condition monitoring of electrical equipment. Manual analysis of thermal image for detecting defects and classifying the status of equipment take a lot of time, efforts and can also lead to incorrect diagnosis results. An intelligent system that can separate the equipment automatically could help to overcome these problems. This paper discusses an intelligent classification system for the conditions of equipment using neural networks. Three sets of features namely first order histogram based statistical, grey level co-occurrence matrix and component based intensity features are extracted by image analysis, which are used as input data for the neural networks. The multilayered perceptron networks are trained using four different training algorithms namely Resilient back propagation, Bayesian Regulazation, Levenberg-Marquardt and Scale conjugate gradient. The experimental results show that the component based intensity features perform better compared to other two sets of features. Finally, after selecting the best features, multilayered perceptron network trained using Levenberg-Marquardt algorithm achieved the best results to classify the conditions of electrical equipment.

Efficiency of vanilla, patchouli and ylang ylang essential oils stabilized by iron oxide@C14 nanostructures against bacterial adherence and biofilms formed by Staphylococcus aureus and Klebsiella pneumoniae clinical strains.  

PubMed

Biofilms formed by bacterial cells are associated with drastically enhanced resistance against most antimicrobial agents, contributing to the persistence and chronicization of the microbial infections and to therapy failure. The purpose of this study was to combine the unique properties of magnetic nanoparticles with the antimicrobial activity of three essential oils to obtain novel nanobiosystems that could be used as coatings for catheter pieces with an improved resistance to Staphylococcus aureus and Klebsiella pneumoniae clinical strains adherence and biofilm development. The essential oils of ylang ylang, patchouli and vanilla were stabilized by the interaction with iron oxide@C14 nanoparticles to be further used as coating agents for medical surfaces. Iron oxide@C14 was prepared by co-precipitation of Fe+2 and Fe+3 and myristic acid (C14) in basic medium. Vanilla essential oil loaded nanoparticles pelliculised on the catheter samples surface strongly inhibited both the initial adherence of S. aureus cells (quantified at 24 h) and the development of the mature biofilm quantified at 48 h. Patchouli and ylang-ylang essential oils inhibited mostly the initial adherence phase of S. aureus biofilm development. In the case of K. pneumoniae, all tested nanosystems exhibited similar efficiency, being active mostly against the adherence K. pneumoniae cells to the tested catheter specimens. The new nanobiosystems based on vanilla, patchouli and ylang-ylang essential oils could be of a great interest for the biomedical field, opening new directions for the design of film-coated surfaces with anti-adherence and anti-biofilm properties.

Heat Shock Protein 90 Functions to Stabilize and Activate the Testis-specific Serine/Threonine Kinases, a Family of Kinases Essential for Male Fertility*  

PubMed Central

Spermiogenesis is characterized by a profound morphological differentiation of the haploid spermatid into spermatozoa. The testis-specific serine/threonine kinases (TSSKs) comprise a family of post-meiotic kinases expressed in spermatids, are critical to spermiogenesis, and are required for male fertility in mammals. To explore the role of heat shock protein 90 (HSP90) in regulation of TSSKs, the stability and catalytic activity of epitope-tagged murine TSSKs were assessed in 293T and COS-7 cells. TSSK1, -2, -4, and -6 (small serine/threonine kinase) were all found to associate with HSP90, and pharmacological inhibition of HSP90 function using the highly specific drugs 17-AAG, SNX-5422, or NVP-AUY922 reduced TSSK protein levels in cells. The attenuation of HSP90 function abolished the catalytic activities of TSSK4 and -6 but did not significantly alter the specific activities of TSSK1 and -2. Inhibition of HSP90 resulted in increased TSSK ubiquitination and proteasomal degradation, indicating that HSP90 acts to control ubiquitin-mediated catabolism of the TSSKs. To study HSP90 and TSSKs in germ cells, a mouse primary spermatid culture model was developed and characterized. Using specific antibodies against murine TSSK2 and -6, it was demonstrated that HSP90 inhibition resulted in a marked decrease of the endogenous kinases in spermatids. Together, our findings demonstrate that HSP90 plays a broad and critical role in stabilization and activation of the TSSK family of protein kinases. PMID:23599433

AIPL1, A protein linked to blindness, is essential for the stability of enzymes mediating cGMP metabolism in cone photoreceptor cells  

PubMed Central

Defects in the photoreceptor-specific gene encoding aryl hydrocarbon receptor interacting protein like-1 (AIPL1) are linked to blinding diseases, including Leber congenital amaurosis (LCA) and cone dystrophy. While it is apparent that AIPL1 is needed for rod and cone function, the role of AIPL1 in cones is not clear. In this study, using an all-cone animal model lacking Aipl1, we show a light-independent degeneration of M- and S-opsin containing cones that proceeds in a ventral-to-dorsal gradient. Aipl1 is needed for stability, assembly and membrane association of cone PDE6, an enzyme crucial for photoreceptor function and survival. Furthermore, RetGC1, a protein linked to LCA that is needed for cGMP synthesis, was dramatically reduced in cones lacking Aipl1. A defect in RetGC1 is supported by our finding that cones lacking Aipl1 exhibited reduced levels of cGMP. These findings are in contrast to the role of Aipl1 in rods, where destabilization of rod PDE6 results in an increase in cGMP levels, which drives rapid rod degeneration. Our results illustrate mechanistic differences behind the death of rods and cones in retinal degenerative disease caused by deficiencies in AIPL1. PMID:24108108

FAP20 is an inner junction protein of doublet microtubules essential for both the planar asymmetrical waveform and stability of flagella in Chlamydomonas.  

PubMed

The axoneme-the conserved core of eukaryotic cilia and flagella-contains highly specialized doublet microtubules (DMTs). A long-standing question is what protein(s) compose the junctions between two tubules in DMT. Here we identify a highly conserved flagellar-associated protein (FAP), FAP20, as an inner junction (IJ) component. The flagella of Chlamydomonas FAP20 mutants have normal length but beat with an abnormal symmetrical three-dimensional pattern. In addition, the mutant axonemes are liable to disintegrate during beating, implying that interdoublet connections may be weakened. Conventional electron microscopy shows that the mutant axonemes lack the IJ, and cryo-electron tomography combined with a structural labeling method reveals that the labeled FAP20 localizes at the IJ. The mutant axonemes also lack doublet-specific beak structures, which are localized in the proximal portion of the axoneme and may be involved in planar asymmetric flagellar bending. FAP20 itself, however, may not be a beak component, because uniform localization of FAP20 along the entire length of all nine DMTs is inconsistent with the beak's localization. FAP20 is the first confirmed component of the IJ. Our data also suggest that the IJ is important for both stabilizing the axoneme and scaffolding intra-B-tubular substructures required for a planar asymmetrical waveform. PMID:24574454

Filamin A (FLNA) plays an essential role in somatostatin receptor 2 (SST2) signaling and stabilization after agonist stimulation in human and rat somatotroph tumor cells.  

PubMed

Somatostatin receptor type 2 (SST2) is the main pharmacological target of medical therapy for GH-secreting pituitary tumors, but molecular mechanisms regulating its expression and signaling are largely unknown. The aim of this study was to investigate the role of cytoskeleton protein filamin A (FLNA) in SST2 expression and signaling in somatotroph tumor cells. We found a highly variable expression of FLNA in human GH-secreting tumors, without a correlation with SST2 levels. FLNA silencing in human tumoral cells did not affect SST2 expression and localization but abolished the SST2-induced reduction of cyclin D1 (-37% ± 15% in control cells, P < .05 vs basal) and caspase-3/7 activation (+63% ± 31% in control cells, P < .05 vs basal). Overexpression of a FLNA dominant-negative mutant that specifically prevents SST2-FLNA binding reduced SST2 expression after prolonged agonist exposure (-55% ± 5%, P < .01 vs untreated cells) in GH3 cells. Moreover, SST2-induced apoptotic effect (77% ± 54% increase of caspase activity, P < .05 vs basal) and SST2-mediated ERK1/2 inhibition (48% ± 17% reduction of ERK1/2 phosphorylation, P < .01 vs basal) were abrogated in cells overexpressing another FLNA mutant that prevents FLNA interaction with partner proteins but not with SST2, suggesting a scaffold function of FLNA in somatotrophs. In conclusion, these data demonstrate that FLNA is involved in SST2 stabilization and signaling in tumoral somatotrophs, playing both a structural and functional role. PMID:24828612

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.

Gene expression of heat shock protein 70 and antioxidant enzymes, oxidative status, and meat oxidative stability of cyclically heat-challenged finishing broilers fed Origanum compactum and Curcuma xanthorrhiza essential oils.  

PubMed

Heat stress in poultry is a serious problem in many countries and has been associated with oxidative stress. Hence, nutritional interventions with antioxidants might be beneficial. Therefore, the effects of dietary Curcuma xanthorrhiza (CX) and Origanum compactum (OC) essential oils on mRNA levels of heat shock protein 70 and antioxidant enzymes, oxidative status, and meat oxidative stability of heat-challenged broilers were studied. Starting on d 25 of age, a control diet and 4 diets containing 200 or 400 mg/kg feed of CX or OC (CX200, CX400, OC200, OC400 diets) were fed to 3 pen replicates of 20 Ross 308 chickens each. From d 28 of age on, the temperature was increased from 22 to 34°C with 50% RH for 5 h daily during 2 wk. Dietary CX or OC did not affect zootechnical performance. Feeding CX400 and both levels of OC increased the a* value in stored breast meat (P < 0.05), and OC diets tended to decrease the thiobarbituric acid reactive substances values in fresh breast meat (P = 0.061). Compared with control, at d 31, feeding CX400 and OC400 reduced mRNA levels of heat shock protein 70 and increased mRNA levels of catalase in kidney and liver (P < 0.05). The mRNA levels of superoxide dismutase were increased at d 31 on the OC400 diet in kidney and on the CX400 diet in heart (P < 0.05). In heart, at d 31, both dietary levels of CX and OC200 resulted in higher glutathione peroxidase activity (P < 0.05). Feeding CX400 increased superoxide dismutase activity in liver, kidney, and heart at d 31 (P < 0.05). Catalase activity was increased in the CX200 and OC400 groups at d 42 (P < 0.05). Feeding CX at both levels and OC200 decreased plasma malondialdehyde concentrations at d 42 (P < 0.05). In conclusion, dietary essential oils rich in simple phenolic compounds offer potential for improving the antioxidant defense against heat stress-induced changes. PMID:24931966

Development of the flatness standard equipment  

NASA Astrophysics Data System (ADS)

Flatness is an important parameter of independent transmission in geometric metrology. The flatness standard is by interferometer and optical flats to implement transmission. Main parts of the flatness standard equipment are composed of a laser point diffraction interference system, one phase shifts system and one image acquisition system. The equipment is three PZTs to drive the ? 300mm reference optical flat to move, only one CCD to adjust attitudes of the optical flats by reflecting spots and capture a series of interference pictures. The whole equipment is placed on a one 1200mm×800mm optical platform, and the optical platform is placed on a ?1800mm vibration-free base. The optical system of the flatness standard equipment is very simple, which only needs a frequency stabilized He-Ne laser and a space filter to construct a point source, one reflecting mirror, one beam splitter, one ? 300mm transparent collimating system, one needle-hole stop, one CCD and its lens.

Drawing Evaluation Report for Sampling Equipment  

SciTech Connect

This document presents the results of a task to update the evaluation of River Protection Project (WP) sampling equipment drawings and updates the assigned drawings category as either essential, support, or general drawings. This report updates the drawing evaluation that was originally done per Engineering Task Plan For Truck 3 & 4 Drawing Compliance and Evaluation. The scope of this report is limited to updating the evaluation and identification of drawing category for drawings of certain tank waste sampling equipment for which the RPP Characterization Project has been assigned custody, including: vapor sampling, grab sampling, auger sampling, all core sampling equipment, and Light Duty Utility Arm (LDUA) (see LMHC contract No. 519, release 10). This report does not address drawings for other waste tank deployed equipment systems having similar assigned custody, such as, Cone Penetrometer system, or Long Length Contaminated Equipment (LLCE). The Cone Penetrometer system, which is depicted on vendor drawings, (not H- series), is not currently turned over to operations for deployment. The LLCE equipment was just recently assigned to Characterization Project and was not included in the original scope for this update and will be addressed in the evaluation update scheduled for later in fiscal year 1999, when equipment ownership is determined.

Development of medical equipment alarm monitoring system.  

PubMed

In a hospital, we use a large number of medical equipment. In these use, I support the safe use by the alarm such as errors from medical equipment. There is the instrument notifying of alarm in communication, but there is the instrument by a sound and the light. For the medical safety management, confirmation of the alarm is important. We thought that stability was improved by integrating alarm from the instrument of the different type. Therefore, we thought that we integrated alarm from medical equipment. We decided to transmit an alarm signal from medical equipment by adding radio module program unit. The type of the radio used IEEE 802.15.4 (ZigBee) at a point of view of low power, International Standard, simple radio equipment. This system deals with only alarm information from medical equipment and does not handle the data. However, we understood that we were helpful very much even if it was only alarm information. We were able to in this way reduce the number of incidents. PMID:23920969

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.

Dairy Equipment Lubrication  

NASA Technical Reports Server (NTRS)

Lake To Lake Dairy Cooperative, Manitowoc, Wisconsin, operates four plants in Wisconsin for processing milk, butter and cheese products from its 1,300 member farms. The large co-op was able to realize substantial savings by using NASA information for improved efficiency in plant maintenance. Under contract to Marshall Space Flight Center, Midwest Research Institute compiled a handbook consolidating information about commercially available lubricants. The handbook details chemical and physical properties, applications, specifications, test procedures and test data for liquid and solid lubricants. Lake To Lake's plant engineer used the handbook to effect savings in maintenance labor and materials costs by reducing the number of lubricants used on certain equipment. Strict U.S. Department of Agriculture and Food and Drug Administration regulations preclude lubrication changes n production equipment, but the co-op's maintenance chief was able to eliminate seven types of lubricants for ancillary equipment, such as compressors and high pressure pumps. Handbook data enabled him to select comparable but les expensive lubricants in the materials consolidation process, and simplified lubrication schedules and procedures. The handbook is in continuing use as a reference source when a new item of equipment is purchased.

What is essential tremor?  

PubMed Central

Classic essential tremor is a clinical syndrome of action tremor in the upper limbs (at least 95% of patients) and less commonly the head, face/jaw, voice, tongue, trunk, and lower limbs, in the absence of other neurologic signs. However, the longstanding notion of that essential tremor is a monosymptomatic tremor disorder is being challenged by a growing literature describing associated disturbances of tandem walking, personality, mood, hearing and cognition. There is also epidemiologic, pathologic and genetic evidence that essential tremor is pathophysiologically heterogeneous. Misdiagnosis of essential tremor is common because clinicians frequently overlook other neurologic signs and because action tremor in the hands is caused by many conditions, including dystonia, Parkinson disease and drug-induced tremor. Thus, essential tremor is nothing more than a syndrome of idiopathic tremulousness, and the challenge for researchers and clinicians is to find specific etiologies of this syndrome. PMID:23591755

Essential medicines for children.  

PubMed

Millions of children die every year before they reach the age of 5?years, of conditions largely treatable with existing medicines. The WHO Model List of Essential Medicines was launched in 1977 to make the most necessary drugs available to populations whose basic health needs could not be met by the existing supply system. During the first 30?years of the Model List of Essential Medicines, children's needs were not systematically considered. After adoption of the 'Better medicines for children' resolution by the World Health Assembly, things changed. The first WHO Model List of Essential Medicines for Children was drawn up by a Paediatric Expert Subcommittee and adopted in October 2007. The most recent, 4th Model List of Essential Medicines for Children was adopted in 2013. Data from country surveys show that access to essential medicines for children is still generally poor; much more work is needed. PMID:25613966

Essential Bacillus subtilis genes  

PubMed Central

To estimate the minimal gene set required to sustain bacterial life in nutritious conditions, we carried out a systematic inactivation of Bacillus subtilis genes. Among ?4,100 genes of the organism, only 192 were shown to be indispensable by this or previous work. Another 79 genes were predicted to be essential. 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

Ultrahigh vacuum equipment described  

NASA Astrophysics Data System (ADS)

Ultrahigh vacuum equipment for filming with a blockade value and a substrate at the temperature of liquid nitrogen. The equipment has the following characteristics: (1) the vacuum chamber is exposed to the atmosphere, the lockade valve can maintain a vacuum of 1 to 10 to the -9 power torr for a long period of time; (2) it greatly reduces the working cycle compared to before the blockade valve was installed; and (3) the temperature of the sample substrate in the vacuum chamber can be adjusted continuously between 77 K and room temperature. The ultrahigh vacuum filming equipment China now produces does not have an ultrahigh vacuum valve, when inserting and removing samples, the pump casing is exposed to the atmosphere so that even after the pump has operated for a time, its limited vacuum is 10 to the -8 power torr. A bakeable metallic blockade valve is installed between the vacuum pump intake and the vacuum chamber to form a fliming device. The device is simple, the vacuum is increased several levels, and it can make samples at different substrate temperatures.

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.

Artifacts and essentialism  

PubMed Central

Psychological essentialism is an intuitive folk belief positing that certain categories have a non-obvious inner “essence” that gives rise to observable features. Although this belief most commonly characterizes natural kind categories, I argue that psychological essentialism can also be extended in important ways to artifact concepts. Specifically, concepts of individual artifacts include the non-obvious feature of object history, which is evident when making judgments regarding authenticity and ownership. Classic examples include famous works of art (e.g., the Mona Lisa is authentic because of its provenance), but ordinary artifacts likewise receive value from their history (e.g., a worn and tattered blanket may have special value if it was one's childhood possession). Moreover, in some cases, object history may be thought to have causal effects on individual artifacts, much as an animal essence has causal effects. I review empirical support for these claims and consider the implications for both artifact concepts and essentialism. This perspective suggests that artifact concepts cannot be contained in a theoretical framework that focuses exclusively on similarity or even function. Furthermore, although there are significant differences between essentialism of natural kinds and essentialism of artifact individuals, the commonalities suggest that psychological essentialism may not derive from folk biology but instead may reflect more domain-general perspectives on the world.

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 Central

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

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.

Orbital construction support equipment  

NASA Technical Reports Server (NTRS)

Approximately 200 separate construction steps were defined for the three solar power satellite (SPS) concepts. Detailed construction scenarios were developed which describe the specific tasks to be accomplished, and identify general equipment requirements. The scenarios were used to perform a functional analysis, which resulted in the definition of 100 distinct SPS elements. These elements are the components, parts, subsystems, or assemblies upon which construction activities take place. The major SPS elements for each configuration are shown. For those elements, 300 functional requirements were identified in seven generic processes. Cumulatively, these processes encompass all functions required during SPS construction/assembly. Individually each process is defined such that it includes a specific type of activity. Each SPS element may involve activities relating to any or all of the generic processes. The processes are listed, and examples of the requirements defined for a typical element are given.

Stabilized Zeeman split laser  

NASA Technical Reports Server (NTRS)

The development of a stablized Zeeman split laser for use in a polarization profilometer is discussed. A Hewlett-Packard laser was modified to stabilize the Zeeman split beat frequency thereby increasing the phase measurement accuracy from the Hewlett-Packard 3 degrees to an accuracy of .01 degrees. The addition of a two layered inductive winding converts the laser to a current controlled oscillator whose frequency is linearly related to coil current. This linear relationship between coil current and laser frequency permits phase locking the laser frequency to a stable crystal controlled reference frequency. The stability of the system is examined and the equipment operation procedures are outlined.

Overview of essential tremor  

PubMed Central

Essential tremor (ET) is one of the most common movement disorders in the world. Despite this, only one medication (propranolol) is approved by the Food and Drug Administration (FDA) to treat it. Fortunately, recent studies have identified some additional medications as treatment of ET. Surgical procedures, such as deep brain stimulation of the ventral intermediate nucleus of the thalamus, offer treatment for refractory tremor. The epidemiology, pathogenesis, and medical and surgical treatment of ET will be discussed in this paper. PMID:20856604

Pharmacotherapy of Essential Tremor  

PubMed Central

Essential tremor (ET) is a common movement disorder but its pathogenesis remains poorly understood. This has limited the development of effective pharmacotherapy. The current therapeutic armamentaria for ET represent the product of careful clinical observation rather than targeted molecular modeling. Here we review their pharmacokinetics, metabolism, dosing, and adverse effect profiles and propose a treatment algorithm. We also discuss the concept of medically refractory tremor, as therapeutic trials should be limited unless invasive therapy is contraindicated or not desired by patients. PMID:24385718

Unattended optical surveillance equipment  

SciTech Connect

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 8mm 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. 7 refs., 4 figs.

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.

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. PMID:21528097

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.

Equipment for thoracoscopy.  

PubMed

The combining of miniaturized video technology with thoracoscopy now allows surgeons to perform a variety of thoracic procedures percutaneously. Both rigid and flexible video thoracoscopes are available. The rigid endoscope has a camera located proximally at the eye-piece and is capable of excellent resolution. However, visualization of the entire pleural cavity is difficult because of the rigid chest wall. Placing the video camera at the distal end of a flexible thoracoscope, as in the electronic video thoracoscope (EVE-L; Fujinon, Wayne, NJ), yields better visualization of these relatively inaccessible areas. However, disadvantages of the flexible thoracoscope include increased expense and complexity, reduced resolution as compared to rigid systems, and the need for a strobed light source, thus making video-assisted surgery more difficult. Thoracoscopic wedge excisions of the lung are now possible because of the adaptation of gastrointestinal staplers for percutaneous use. The initial design consisted of a reloadable 30-mm disposable stapler. Newer models, however, have a longer staple line and some are reusable. Future refinements may allow the head of the instrument to articulate, thus permitting it to be applied to the lung at various angles. Thoracoscopic ports that provide an air-tight seal are available but are not essential; therefore, standard thoracotomy instruments can be utilized through small open incisions. Specialized disposable thoracoscopic instruments are also available, including scissors, dissectors, and fan retractors. It is hoped that the future will bring improved optics, better staplers, and refined percutaneous instrumentation. PMID:8379754

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.

Difficult airway equipment: a survey of standards across metropolitan Perth.  

PubMed

The importance of appropriate equipment to manage the difficult airway has been highlighted by the publication of the Australian and New Zealand College of Anaesthetists (ANZCA) guidelines in 2012. We set out to audit compliance with these guidelines in all public and private sites providing general anaesthesia in metropolitan Perth. Public and private health care websites identified 39 sites of which 37 were studied. Institutional and ethics approval was obtained. A tick-box design audit tool, based on the ANZCA guidelines, was used to collect information regarding the dedicated difficult airway container (DDAC) at each site. As recommended in the guidelines, only equipment within the DDAC was considered. Further data about each site, including the number of theatre suites, satellite anaesthetic areas, use of capnography and categories of patients treated (adult, obstetric and paediatric) were collected. An adult DDAC was found at 92% of all sites, but none of the sites had all the essential equipment listed in the ANZCA guidelines. There was limited provision of adult difficult airway equipment within private sites compared to public, and less provision of paediatric difficult airway equipment across all sites treating paediatric patients in metropolitan Perth. Capnography was available in 76% of post anaesthesia care units and used regularly in 27%. Adherence to the ANZCA guidelines regarding the DDAC could be improved. Standardised equipment across a metropolitan region would be of value in the management of the difficult airway. PMID:25233181

Personal protective equipment and decontamination of adults and children.  

PubMed

Accurate identification of the hazardous material is essential for proper care. Efficient hospital security and triage must prevent contaminated victims from entering the emergency department (ED) and causing secondary contamination. The decontamination area should be located outside the ambulance entrance. Decontamination priorities are protection of the health care worker, utilization of Level C personal protective equipment, and proper decontamination of the exposed patient. Decontamination proceeds in a head-to-toe sequence. Run-off water is a hazardous waste. Hospital and Community Management Planning for these emergencies is essential for proper preparation and effective response to the hazardous materials incident. PMID:25455662

Near equipment magnetic field verification and scaling  

NASA Astrophysics Data System (ADS)

Magnetic field measurements are essential to the success of many scientific space missions. Outside of the Earth's magnetic field the biggest potential source of magnetic field contamination of these measurements is emitted by the spacecraft. Spacecraft magnetic cleanliness is enforced through the application of strict ground verification requirements for spacecraft equipment and instruments. Due to increasingly strict AC magnetic field requirements, many spacecraft units cannot be verified on the ground using existing techniques. These measurements must instead be taken close to the equipment under test (EUT) and then extrapolated. A traditional dipole power law of -3 (with a field fall-off proportional to r-3) cannot be applied at these close distances without risk of underestimating the field emitted by the EUT, but we demonstrate that a power law of -2 is too conservative. We propose a compromise that uses a power law of -2 up to a distance equal to 3 times the unit size, beyond which a dipole power law can be applied. When extrapolating from a distance of 0.20 to 1.00 m from the centre of a 0.20 m wide EUT, we demonstrate that this method avoids an underprediction of the field, and is at least twice as accurate as performing the extrapolation with a fixed power law of -2.

Laser Frequency Stabilization  

NASA Technical Reports Server (NTRS)

Laser ranging and interferometry are essential technologies allowing for many astounding new spacebased missions such as the Laser Interferometer Space Antenna (LISA) to measure gravitational radiation emitted from distant super massive black hole mergers or distributed aperture telescopes with unprecedented angular resolution in the NIR or visible regime. The requirements on laser frequency noise depend on the residual motion and the distances between the spacecraft forming the interferometer. The intrinsic frequency stability of commercial lasers is several orders of magnitude above these requirements. Therefore, it is necessary for lasers to be stabilized to an ultrastable frequency reference so that they can be used to sense and control distances between spacecraft. Various optical frequency references and frequency stabilization schemes are considered and investigated for the applicability and usefulness for space-based interferometry missions.

Essentials of glomerulotubular balance.  

PubMed

In the proximal tubules, fractional reabsorption remains essentially unchanged during variations in glomerular filtration rate (GFR). Glomerulotubular balance (GTB), defined as the linear relationship between proximal tubular reabsorption and GFR, is quantitatively the most important regulator of tubular reabsorption, which may be stopped by inhibiting Na, K-ATPase activity completely. However, ouabain in doses inhibiting 80% of the Na, K-ATPases, exerts no effect on proximal reabsorption of water, NaCl and NaHCO3. At constant plasma pH, the same relationship between filtered and reabsorbed bicarbonate is obtained whether bicarbonate reabsorption is altered by varying GFR or plasma concentration of bicarbonate. In contrast, a selective rise in plasma NaCl concentration at constant plasma pH (hypernatremia) reduces NaHCO3 reabsorption and fails to stimulate NaCl reabsorption. Other characteristics of proximal tubular reabsorption are that nonreabsorbable solutes, such as mannitol, inhibit water and NaCl reabsorption with little or no change in NaHCO3 reabsorption and renal oxygen consumption. Mannitol reduces the slope of the GTB curve for NaCl but not for NaHCO3. Hypertonic NaHCO3 exerts an osmotic effect on proximal water and NaCl reabsorption comparable to that of mannitol, whereas hypertonic NaCl is without osmotic effect. By reducing plasma pH (hypercapnia at high plasma bicarbonate concentration), the slope of the GTB curves for NaCl and NaHCO3 can be greatly increased. By raising plasma pH either by hypocapnia or bicarbonate loading, proximal reabsorption of NaHCO3 and NaCl is greatly depressed and remains almost unaltered during variations of GFR (abolished GTB). Similarly, carbonic anhydrase inhibitors, such as acetazolamide, reduce the reabsorption of NaCl and NaHCO3 in the same proportion as a rise in plasma pH, and abolish GTB. Examinations of proximal tubular oxygen consumption indicate that the energy requirement for NaHCO3 reabsorption is as expected for transcellular transport by Na, K-ATPases, whereas proximal NaCl reabsorption requires no additional energy. These data indicate that transcellular energy-requiring NaHCO3 reabsorption provides the main osmotic force across the tight junction for paracellular reabsorption of proximal tubular fluid containing NaCl and other solutes of low reflection coefficient. The main factors influencing GTB are the filtered load of bicarbonate, plasma pH and nonreabsorbable solutes in the proximal tubular fluid. PMID:2672697

Analyzing the dynamic behavior of downhole equipment during drilling  

SciTech Connect

Advanced geothermal drilling systems will require a bottom hole assembly (BHA) which utilizes sophisticated electronic and mechanical equipment to accomplish faster, more trouble free, smarter drilling. The bit-drill string/formation interaction during drilling imposes complex, intermittent dynamic loading on the downhole equipment. A finite element computer code, GEODYN, is being developed to allow analysis of the structural response of the downhole equipment during drilling and to simulate the drilling phenomena (i.e. penetration, direction, etc.). Phase 1 GEODYN, completed early in 1984, provides the capability to model the dynamic response of a polycrystalline diamond compact (PDC) bit interacting with a non-homogeneous formation. Succeeding development phases will allow inclusion of stabilizers and, eventually, the entire drill string in addition to facilitating drill ahead simulation.

Greenhouse heating equipment selection spreadsheet  

SciTech Connect

A large percentage of the projects in which the Geo-Heat Center has participated have been greenhouses. In most cases, our involvement has been related to the selection of heating equipment for the structure. The wide variety of equipment, growers preferences and resource temperatures can make the selection a complicated process. As with any project, the cost of the equipment is a primary consideration. To manually evaluate the cost of five or six alternate systems for each project is prohibitive due to the time required. As a result of these issues, the Geo-Heat Center has developed a spreadsheet entitled [open quotes]Greenhouse Heating Equipment Selection[close quotes] (GHS). GHS is a tool for evaluating the cost (both capital and operating) of six types of greenhouse heating systems: unit heaters, finned pipe, bare tube, fan coil, combination bare tube/fan coil and low temperature unit heaters. A future modification of the spreadsheet will allow a propane unit heater peaking system to be added to any of the above systems.

The conventional method to stabilize the spine is to suspend the rostral and caudal cervical spine via clamps attached to cervical spinous processes.  However, this method of stabilization fails to prevent tissue yielding during the contusion as the cervical spinal processes are too short to be effectively secured by the clamps (Figure 1).  Here we introduce a new method to completely stabilize the cervical vertebra at the same level of the impact injury.  This method effectively minimizes movement of the spinal column at the site of impact, which greatly improves the production of consistent SCIs.  We provide visual description of the equipment (Figure 2-4), methods, and a step-by-step protocol for the stabilization of the cervical 5 vertebra (C5) of adult rats, to perform laminectomy (Figure 5) and produce a contusive SCI thereafter.  Although we only demonstrate a cervical hemi-contusion using the NYU/MASCIS impactor device, this vertebral stabilization technique can be applied to other regions of the spinal cord, or be adapted to other SCI devices.  Improving spinal cord exposure and fixation through vertebral stabilization may be valuable for producing consistent and reliable injuries to the spinal cord.  This vertebral stabilization method can also be used for stereotactic injections of cells and tracers, and for imaging using two-photon microscopy in various neurobiological studies.

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

Neuroimaging essentials in essential tremor: A systematic review  

PubMed Central

Background Essential tremor is regarded to be a disease of the central nervous system. Neuroimaging is a rapidly growing field with potential benefits to both diagnostics and research. The exact role of imaging techniques with respect to essential tremor in research and clinical practice is not clear. A systematic review of the different imaging techniques in essential tremor is lacking in the literature. Methods We performed a systematic literature search combining the terms essential tremor and familial tremor with the following keywords: imaging, MRI, VBM, DWI, fMRI, PET and SPECT, both in abbreviated form as well as in full form. We summarize and discuss the quality and the external validity of each study and place the results in the context of existing knowledge regarding the pathophysiology of essential tremor. Results A total of 48 neuroimaging studies met our search criteria, roughly divided into 19 structural and 29 functional and metabolic studies. The quality of the studies varied, especially concerning inclusion criteria. Functional imaging studies indicated cerebellar hyperactivity during rest and during tremor. The studies also pointed to the involvement of the thalamus, the inferior olive and the red nucleus. Structural studies showed less consistent results. Discussion and conclusion Neuroimaging techniques in essential tremor give insight into the pathophysiology of essential tremor indicating the involvement of the cerebellum as the most consistent finding. GABAergic dysfunction might be a major premise in the pathophysiological hypotheses. Inconsistencies between studies can be partly explained by the inclusion of heterogeneous patient groups. Improvement of scientific research requires more stringent inclusion criteria and application of advanced analysis techniques. Also, the use of multimodal neuroimaging techniques is a promising development in movement disorders research. Currently, the role of imaging techniques in essential tremor in daily clinical practice is limited. PMID:25068111

Stabilizing Microwave Frequency of a Photonic Oscillator  

NASA Technical Reports Server (NTRS)

A scheme for stabilizing the frequency of a microwave signal is proposed that exploits the operational characteristics of a coupled optoelectronic oscillator (COEO) and related optoelectronic equipment. An essential element in the scheme is a fiber mode-locked laser (MLL), the optical frequency of which is locked to an atomic transition. In this scheme, the optical frequency stability of the mode-locked laser is transferred to that of the microwave in the same device. Relative to prior schemes for using wideband optical frequency comb to stabilize microwave signals, this scheme is simpler and lends itself more readily to implementation in relatively compact, rugged equipment. The anticipated development of small, low-power, lightweight, highly stable microwave oscillators based on this scheme would afford great benefits in communication, navigation, metrology, and fundamental sciences. COEOs of various designs, at various stages of development, in some cases called by different names, have been described in a number of prior NASA Tech Briefs articles. A COEO is an optoelectronic apparatus that generates both short (picosecond) optical pulses and a steady microwave signal having an ultrahigh degree of spectral purity. The term "coupled optoelectronic" in the full name of such an apparatus signifies that its optical and electronic oscillations are coupled to each other in a single device. The present frequency-stabilization scheme is best described indirectly by describing the laboratory apparatus used to demonstrate it. The apparatus (see figure) includes a COEO that generates a comb-like optical spectrum, the various frequency components of which interfere, producing short optical pulses. This spectrum is centered at a nominal wavelength of 1,560 nm. The spectrum separation of this comb is about 10 GHz, as determined primarily by the length of an optical loop and the bandpass filter in the microwave feedback loop. The optical loop serves as microwave resonator having a very high value of the resonance quality factor (Q). The optical frequency of MLL is then stabilized by locking it to an atomic transition as described below. The COEO contains a tunable 1-nm band-pass optical filter and a piezoelectric-transducer (PZT) drum over which a stretch of fiber is wound. The 1-nm-wide pass band of the filter provides coarse tuning to overlap the frequency comb with the atomic transition frequency. Controlled stretching of the fiber by means of the PZT drum can be used in conjunction with temperature control for locking the laser frequency. To reference to an atomic resonance at 780 nm in this demonstration setup, the optical output of the COEO at 1,560 nm is fed through an erbium-doped-fiber amplifier (EDFA) to a frequency doubler in the form of a periodically poled lithium niobate (PPLN) crystal. The frequency-doubled output is combined with the output of a separate frequency-stabilized diode laser at a photodetector. As described thus far, the two 780-nm laser subsystems are nominally independent of each other and can, therefore, operate at different frequencies. Hence, at the photodetector, the two laser beams interfere, so that the output of the photodetector includes a beat note (a component at the difference between the two laser frequencies).

Essential Spaceflight Dynamics and Magnetospherics  

NASA Astrophysics Data System (ADS)

The present book Essential Spaceflight Dynamics and Magnetospherics describes, in the first instance, some of the key aspects of celestial mechanics and spaceflight dynamics. It begins with classical two- and three-body problems illustrative of the aesthetic aspects of applying analytical methods of investigation to celestial mechanics. Then, osculating orbital elements are introduced as well as analysis techniques sufficient to evaluate the influence of various disturbing forces on spacecraft. Next a theory of manoeuvres is outlined and the methodology of making interplanetary trajectory corrections. Ideas involving various approaches to orbital element determinations using measured data are also considered. The forces applied to a spacecraft can result in the development of torques that influence attitude motion and the effects of the most important of these are described in terms of equilibrium positions, periodic motions, steady-state and transient motions. Also considered is the problem of attitude control of a spacecraft using active and/or passive methods of orientation and stabilization. In addition, a more advanced treatment of the development of attitude control systems is provided. A description of the Earth's magnetic and gravitational fields allows clarification of the relationship between natural features of the Earth's environment and the requirements of mission design, orbit construction and approaches to attitude control. A detailed Addendum provides an overview of circumstances on the Sun that render interplanetary space a very hazardous environment for spacecraft and for `man in space'. The influence of this environment on spacecraft performance and survival is then presented, together with an outline of some of the mitigating strategies that can be invoked. A feature of this Addendum is the indication it provides of the challenges that the next generation of space experiments will pose to mission designers. It is accompanied by a separate set of references since if refers to ongoing work in space physics rather than to classical material. Rauschenbakh, Boris Victorovich (1915-2001).

Assessment of HYGAS mechanical equipment  

SciTech Connect

The HYGAS process, which converts coal to substitute natural gas, is being developed by the Institute of Gas Technology (IGT) using an 80 ton per day pilot plant located in Chicago, Illinois. Plant design started in 1967 and testing began in October 1971. Since then, 18,000 tons of both Eastern and Western coal have been gasified. Assessment of the mechanical equipment was made by Mechanical Technology Incorporated (MTI) in collaboration with a DOE on-site representative and a representative from IGT, the operating contractor. Data for the assessment were obtained by reviewing all available maintenance records, by interviewing key personnel from maintenance and operations, and by observing repairs and maintenance procedures where possible. While operating the plant, a variety of equipment problems were addressed, many of which are generic to HYGAS as well as other coal conversion processes. Some problems were solved completely while others were solved to suit the limited needs of the pilot plant. Accordingly, the emphasis of this study is on the degree of success in dealing with equipment failures, the unresolved problems and the implication to future coal conversion plants.

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.

Complete sodium removal from equipment  

SciTech Connect

Proving that metallic sodium could be successfully removed from the complex internal and external geometries of equipment (such as breeder reactor components) was one goal of the US Department of Energy's (DOE's) Sodium Waste Technology Program. A pilot-plant facility was designed and built for sodium removal at the Argonne National Laboratory-West (ANL-W) site. The pilot plant is called the Sodium Process Demonstration (SPD) Facility. It uses a combination of melt-drain-evaporate-calcine (MEDEC) processes to remove metallic sodium from large (up to 1.4-m-diam x 2.2-m-long) nonradioactive-sodium-bearing equipment. The sodium-free equipment can then be reused or disposed of using normal waste disposal methods. The sodium can be converted to storable sodium monoxide or disposed of by other means. Evaluating the effectiveness of this MEDEC process was the object of a methodical test program. After this test program proved successful, the MEDEC process was used on a production scale to remove metallic sodium from a variety of sodium-bearing items as described.

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.

Effect of firefighters' personal protective equipment on gait.  

PubMed

The biomechanical experiment with eight male and four female firefighters demonstrates that the effect of adding essential equipment: turnout ensemble, self-contained breathing apparatus, and boots (leather and rubber boots), significantly restricts foot pronation. This finding is supported by a decrease in anterior-posterior and medial-lateral excursion of center of plantar pressure (COP) trajectory during walking. The accumulation of this equipment decreases COP velocity and increases foot-ground contact time and stride time, indicating increased gait instability. An increase in the flexing resistance of the boots is the major contributor to restricted foot pronation and gait instability as evidenced by the greater decrease in excursion of COP in leather boots (greater flexing resistance) than in rubber boots (lower resistance). The leather boots also shows the greatest increase in foot contact time and stride time. These negative impacts can increase musculoskeletal injuries in unfavorable fire ground environments.

Preventive Maintenance Prioritization Index of Medical Equipment Using Quality Function Deployment.  

PubMed

Preventive maintenance is a core function of clinical engineering and it is essential to guarantee the correct functioning of the equipment. The management and control of maintenance activities are equally important to perform maintenance. As the variety of medical equipment increases, accordingly the size of maintenance activities increases, the need for better management and control become essential. This article aims to develop a new model for preventive maintenance priority of medical equipment using quality function deployment (QFD) as a new concept in maintenance of medical equipment. We developed a 3 domain framework model consisting of requirement, function, and concept. The requirement domain is the house of quality matrix (HOQ). The second domain is the design matrix. Finally, the concept domain generates a prioritization index for preventive maintenance considering the weights of critical criteria. According to the final scores of those criteria, the prioritization action of medical equipment is carried out. Our model proposes 5 levels of priority for preventive maintenance. The model was tested on 200 pieces of medical equipment belonging to 17 different departments of 2 hospitals in Piedmont province, Italy. The data set includes 70 different types of equipment. The results show a high correlation between risk - based criteria and the prioritization list. PMID:25029522

The use of bulk-acoustic-wave (BAW) time-delay lines in stability testing equipment for S- and L-band MTI radars is discussed. The importance of radar stability for MTI performance and the need for time delays in stability testing are explained; the disadvantages of using echo returns from known targets are reviewed; and it is pointed out that BAW devices operating at S or L band have a maximum delay time of 15 microsec. Calculations are presented which demonstrate that this delay is adequate for accurate stability measurements. The BAW-based system has been applied successfully to an airport surveillance radar, a terminal Doppler weather radar, and a NEXRAD weather radar; its compact design makes it suitable for inclusion in built-in test equipment.

Thermal design and flight validation for laser communicator equipment  

NASA Astrophysics Data System (ADS)

Laser communicator equipment, designed for advanced optical communication, with a large capacity communication, good encryption and lightweight structures, etc., has a wide range of applications. As for the special transmission characteristic of optical communication, laser phase in the transmission path should be accurate, and less thermal deformation for the optical parts is required in the working process, so the laser communicator equipment has a high level requirement for temperature. Large power units cooling, outer two-dimensional rotating units, temperature control for rotating cable, and high temperature stability and equality, bring a challenge for thermal design. Using structure -electric-thermo-optical integration technology, active and passive thermal control methods are adopt in thermal design for laser communicator equipment: heat-conducted plate and heat pipe were adopted for heat transfer of high heat-flux parts, a new passive and active thermal control method to solve cable cryogenic problems, and high precision temperature control methods were applied for key parts. In-orbit data were analyzed, and the results prove the thermal design correct, and bring a way to thermal control for the equipment with high heat flux and running parts.

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. PMID:22869722

General aviation avionics equipment maintenance  

NASA Technical Reports Server (NTRS)

Maintenance of general aviation avionics equipment was investigated with emphasis on single engine and light twin engine general aviation aircraft. Factors considered include the regulatory agencies, avionics manufacturers, avionics repair stations, the statistical character of the general aviation community, and owners and operators. The maintenance, environment, and performance, repair costs, and reliability of avionics were defined. It is concluded that a significant economic stratification is reflected in the maintenance problems encountered, that careful attention to installations and use practices can have a very positive impact on maintenance problems, and that new technologies and a general growth in general aviation will impact maintenance.

Fire suppression and detection equipment  

SciTech Connect

Inspection and testing guidelines go beyond the 'Code of Federal Regulation'. Title 30 of the US Code of Federal Regulations (30 CFR) contains requirements and references to national standards for inspection, testing and maintenance of fire suppression and detection equipment for mine operators. However, federal requirements have not kept pace with national standards and best practices. The article lists National Fire Protection (NFPA) standards that are referenced by the US Mine Safety and Health Administration (MSHA) in 30 CFR. It then discusses other NFPA Standards excluded from 30 CFR and explains the NFPA standard development process. 2 refs., 3 tabs., 5 photos.

Dara vestibular equipment onboard MIR  

NASA Astrophysics Data System (ADS)

We have described the vestibular and visuo-oculomotoric equipment which has been developed under various DARA contracts since 1991, and used aboard MIR in the frame of the following missions: • German MIR'92 mission (VOG) • Extensions to MIR '92, e.g. the use of VOG by V. Polyakov during his record stay in space from 1993 to 1994 • EUROMIR'94 (VOG) • EUROMIR'95 (VOG, OKS and BIVOG) • Joint German /Russian experiments in 1997/98 (BIVOG) The hardware is supplemented by various stimuli and measurements. New developments for a next generation BIVOG, which may become the Space Station 3D eye tracking system, have shortly been addressed.

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.

The area of biocatalysis itself is in rapid development, fueled by both an enhanced repertoire of protein engineering tools and an increasing list of solved problems. Biocatalysts, however, are delicate materials that hover close to the thermodynamic limit of stability. In many cases, they need to be stabilized to survive a range of challenges regarding temperature, pH value, salt type and concentration, co-solvents, as well as shear and surface forces. Biocatalysts may be delicate proteins, however, once stabilized, they are efficiently active enzymes. Kinetic stability must be achieved to a level satisfactory for large-scale process application. Kinetic stability evokes resistance to degradation and maintained or increased catalytic efficiency of the enzyme in which the desired reaction is accomplished at an increased rate. However, beyond these limitations, stable biocatalysts can be operated at higher temperatures or co-solvent concentrations, with ensuing reduction in microbial contamination, better solubility, as well as in many cases more favorable equilibrium, and can serve as more effective templates for combinatorial and data-driven protein engineering. To increase thermodynamic and kinetic stability, immobilization, protein engineering, and medium engineering of biocatalysts are available, the main focus of this work. In the case of protein engineering, there are three main approaches to enhancing the stability of protein biocatalysts: (i) rational design, based on knowledge of the 3D-structure and the catalytic mechanism, (ii) combinatorial design, requiring a protocol to generate diversity at the genetic level, a large, often high throughput, screening capacity to distinguish 'hits' from 'misses', and (iii) data-driven design, fueled by the increased availability of nucleotide and amino acid sequences of equivalent functionality.

A simplified spatial model for BWR stability  

SciTech Connect

A spatial reduced order model for the study of BWR stability, based on the phenomenological model of March-Leuba et al., is presented. As one dimensional spatial dependence of the neutron flux, fuel temperature and void fraction is introduced, it is possible to describe both global and regional oscillations of the reactor power. Both linear stability analysis and numerical analysis were applied in order to describe the parameters which govern the model stability. The results were found qualitatively similar to past results. Doppler reactivity feedback was found essential for the explanation of the different regions of the flow-power stability map. (authors)

Subsea production equipment standardization initiative  

SciTech Connect

This paper examines Shell Expro`s work in simplifying and standardizing its subsea production systems on 10,000 psi, 300 F rated equipment through the use of proven technology and configured to meet common interface requirements. A modular ``building block`` approach to design was adopted, whereby trees are easily converted from one style to another (oil, water or gas lift) by the addition or removal of bolt-on, pre-engineered packages. Standardization of associated control systems has also been applied, together with series hook-up of trees for small developments. A common top-of-tree interface enables vendor interchangeability of tooling. The use of ROV compatible designs for choke and control module change out are expected to provide significant operational cost savings. Common interfaces allow cross-sharing of tooling systems between projects and potentially other operators, and are the catalyst for vendors to develop rental tooling pools.

Leukemic transformation in essential thrombocythemia.  

PubMed

Essential thrombocythemia patients develop acute myeloid leukemia (AML) at a rate of 1-4% during a median follow-up of 7-10 years. The risk increases with advanced age, anemia, platelet count ? 1000 × 10(9)/l, the presence of ? 2 somatic mutations and after the first decade of diagnosis. The use of alkylating agents and (32)radiophosphorus, particularly in higher doses, but not hydroxyurea and anagrelide, increases the risk. AML in essential thrombocythemia patients is frequently associated with unfavorable cytogenetics and poor prognosis. In young and fit patients, AML-type induction chemotherapy followed by allogeneic stem cell transplantation may offer the best chance of long-term disease control. In select elderly patients with poor performance status, hypomethylating agent such as azacytidine may prolong survival. PMID:25531047

Stability Tunnel  

NASA Technical Reports Server (NTRS)

Engineers operate the controls of the Stability Tunnel: Plans for a new tunnel to study stability problems began in the late thirties. The Stability Tunnel was authorized in 1939 and began operations in June 1941. The installation was completed in December that year with the completion of a new 10,000 Horsepower Diesel-electric generating plant. It was a single return, closed jet tunnel with a 6-foot square test section. The tunnel was disassembled and shipped to Virginia Polytechnic Institute and State University in 1958. The tunnel had two separate test sections: one for curved flow, the other for rolling flow. 'The facility...simulates the motion of the aircraft in curved or rolling flight. This is done by actually curving or rolling the airstream as it passes over the model and at the same time providing the proper velocity distribution.' (From AIAA-80-0309) >From Alan Pope, Wind-Tunnel Testing: 'The only tunnel directly designed for dynamic stability work is located at the Langley Field branch of the NACA. Its most vital feature is its ability to subject the models to curving air streams that simulate those actually encountered when an airplane rolls, pitches, or yaws. the rotating airstream for simulating roll is produced by a motor-driven paddle just ahead of the test section. Curved air of properly varying velocity for simulating pitch and yaw is produced by a combination of a curved test section and velocity screens. The proper use of this apparatus makes possible the determination of the stability derivatives.' (pp. 13-14)

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. .

MOV surge arresters: improved substation equipment protection  

SciTech Connect

The introduction of metal-oxide-varistor (MOV) surge arresters has added a new dimension to substation equipment protection. Through the optimal use of these arresters, it is possible to lower surge arrester ratings and thereby improve protective margins, resulting in a possible reduction of the insulation levels (BIL) of substation equipment. This reduction in BIL can lead to a significant reduction in the cost of substation equipment. General methods are delineated for selecting MOV surge arresters for substation protection and the resulting effect on substation equipment insulation levels.

Stability of casein micelles in milk  

NASA Astrophysics Data System (ADS)

Casein micelles in milk are proteinaceous colloidal particles and are essential for the production of flocculated and gelled products such as yogurt, cheese, and ice-cream. The colloidal stability of casein micelles is described here by a calculation of the pair potential, containing the essential contributions of brush repulsion, electrostatic repulsion, and van der Waals attraction. The parameters required are taken from the literature. The results are expressed by the second osmotic virial coefficient and are quite consistent with experimental findings. It appears that the stability is mainly attributable to a steric layer of ?-casein, which can be described as a salted polyelectrolyte brush.

Economic demand and essential value.  

PubMed

The strength of a rat's eating reflex correlates with hunger level when strength is measured by the response frequency that precedes eating (B. F. Skinner, 1932a, 1932b). On the basis of this finding, Skinner argued response frequency could index reflex strength. Subsequent work documented difficulties with this notion because responding was affected not only by the strengthening properties of the reinforcer but also by the rate-shaping effects of the schedule. This article obviates this problem by measuring strength via methods from behavioral economics. This approach uses demand curves to map how reinforcer consumption changes with changes in the "price" different ratio schedules impose. An exponential equation is used to model these demand curves. The value of this exponential's rate constant is used to scale the strength or essential value of a reinforcer, independent of the scalar dimensions of the reinforcer. Essential value determines the consumption level to be expected at particular prices and the response level that will occur to support that consumption. This approach permits comparing reinforcers that differ in kind, contributing toward the goal of scaling reinforcer value. PMID:18211190

Clonal evolution in essential thrombocythemia  

SciTech Connect

Essential thombocythemia is a myeloproliferative disorder characterized by an increased production of platelets and marrow megakaryocytes. It is generally believed to be a clonal disorder involving a multipotent stem cell for granulocytes, erythrocytes and platelets. To date, no consistant chromosomal rearrangement has been associated with this disease. We present a case in clonal evolution, having one population of cells with a complex rearrangement involving duplication of chromosome 11 dup(11)(q13q25) in 50% of the dividing marrow population. A second population of cells that evolved from the first population, representing the remaining 50% of the marrow cells, had the derivative 11 with the duplication on the q arm plus an additional translocation with chromosome 17q on the p arm, der(11)t(11;17)(q15;q21) dup(11)(q13q25). Whole chromosome 11 and whole chromosome 17 painting probes (Oncor, Gaitersburg, MD) were applied to verify the 11 duplication and the 17 translocation and to determine the percentage of each clone in the marrow population. It is essential to determine the percentage of each clone to assess disease progression. It is also important to identify the derivative 11 in this case for the myeloproliferative disorders have a tendency to progress to acute nonlymphatic leukemia (ANLL) and the involvement of chromosome 11 in that disease is well-documented.

Essential Tremor: A Neurodegenerative Disease?  

PubMed Central

Background Essential tremor (ET) is one of the most common neurological disorders among adults, and is the most common of the many tremor disorders. It has classically been viewed as a benign monosymptomatic condition, yet over the past decade, a growing body of evidence indicates that ET is a progressive condition that is clinically heterogeneous, as it may be associated with a spectrum of clinical features, with both motor and non-motor elements. In this review, I will describe the most significant emerging milestones in research which, when taken together, suggest that ET is a neurodegenerative condition. Methods A PubMed search conducted in June 2014 crossing the terms “essential tremor” (ET) and “neurodegenerative” yielded 122 entries, 20 of which included the term “neurodegenerative” in the article title. This was supplemented by articles in the author's files that pertained to this topic. Results/Discussion There is an open and active dialogue in the medical community as to whether ET is a neurodegenerative disease, with considerable evidence in favor of this. Specifically, ET is a progressive disorder of aging associated with neuronal loss (reduction in Purkinje cells) as well as other post-mortem changes that occur in traditional neurodegenerative disorders. Along with this, advanced neuroimaging techniques are now demonstrating distinct structural changes, several of which are consistent with neuronal loss, in patients with ET. However, further longitudinal clinical and neuroimaging longitudinal studies to assess progression are required. PMID:25120943

[Antioxidant properties of essential oils from lemon, grapefruit, coriander, clove, and their mixtures].  

PubMed

Antioxidant properties of individual essential oils from lemon (Citrus limon L.), pink grapefruit (Citrus paradise L.), coriander (Coriandrum sativum L.), and clove (Caryophyllus aromaticus L.) buds and their mixtures were studied by capillary gas-liquid chromatography. Antioxidant activity was assessed by oxidation of the aliphatic aldehyde hexanal to the carboxylic acid. The lowest and highest antioxidant activities were exhibited by grapefruit and clove bud essential oils, respectively. Mixtures containing clove bud essential oil also strongly inhibited oxidation of hexanal. Changes in the composition of essential oils and their mixtures in the course of long-term storage in the light were studied. The stability of components of lemon and coriander essential oils in mixtures increased compared to individual essential oils. PMID:18924419

Office equipment energy use and trends  

SciTech Connect

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.

Automatic monitoring of vibration welding equipment  

DOEpatents

A vibration welding system includes vibration welding equipment having a welding horn and anvil, a host device, a check station, and a robot. The robot moves the horn and anvil via an arm to the check station. Sensors, e.g., temperature sensors, are positioned with respect to the welding equipment. Additional sensors are positioned with respect to the check station, including a pressure-sensitive array. The host device, which monitors a condition of the welding equipment, measures signals via the sensors positioned with respect to the welding equipment when the horn is actively forming a weld. The robot moves the horn and anvil to the check station, activates the check station sensors at the check station, and determines a condition of the welding equipment by processing the received signals. Acoustic, force, temperature, displacement, amplitude, and/or attitude/gyroscopic sensors may be used.

DARA vestibular equipment onboard MIR.  

PubMed

In space, the weightless environment provides a different stimulus to the otolith organs of the vestibular system, and the resulting signals no longer correspond with the visual and other sensory signals sent to the brain. This signal conflict causes disorientation. To study this and also to understand the vestibular adaptation to weightlessness, DARA has developed scientific equipment for vestibular and visuo-oculomotoric investigations. Especially, two video-oculography systems (monocular--VOG--and binocular--BIVOG, respectively) as well as stimuli such as an optokinetic stimulation device have successfully been employed onboard MIR in the frame of national and European missions since 1992. The monocular VOG was used by Klaus Flade during the MIR '92 mission, by Victor Polyakov during his record 15 months stay onboard MIR in 1993/94 as well as by Ulf Merbold during EUROMIR '94. The binocular version was used by Thomas Reiter and Sergej Avdeyev during the 6 months EUROMIR '95 mission. PIs of the various experiments include H. Scherer and A. Clarke (FU Berlin), M. Dieterichs and S. Krafczyk (LMU Munchen) from Germany as well as C.H. Markham and S.G. Diamond from the United States. Video-Oculography (VOG) is a technique for examining the function of the human balance system located in the inner ear (vestibular system) and the visio-oculomotor interactions of the vestibular organ. The human eye movements are measured, recorded and evaluated by state-of-the-art video techniques. The method was first conceived and designed at the Vestibular Research Laboratory of the ENT Clinic in Steglitz, FU Berlin (A. Clarke, H. Scherer). Kayser-Threde developed, manufactured and tested the facilities for space application under contract to DARA. Evaluation software was first provided by the ENT Clinic, Berlin, later by our subcontractor Sensomotoric Instruments (SMI), Teltow. Optokinetic hardware to support visuo-oculomotoric investigations, has been shipped to MIR for EUROMIR '95 and has successfully been used in conjunction with VOG by ESA astronaut Thomas Reiter. Most recently, BIVOG aboard MIR will be reused in the frame of German/Russian joint experiment sessions employing two Russian cosmonauts from August 1997 to January 1998. PMID:11541933

Antioxidant activity of essential oils.  

PubMed

Essential oils (EOs) are liquid mixtures of volatile compounds obtained from aromatic plants. Many EOs have antioxidant properties, and the use of EOs as natural antioxidants is a field of growing interest because some synthetic antioxidants such as BHA and BHT are now suspected to be potentially harmful to human health. Addition of EOs to edible products, either by direct mixing or in active packaging and edible coatings, may therefore represent a valid alternative to prevent autoxidation and prolong shelf life. The evaluation of the antioxidant performance of EOs is, however, a crucial issue, because many commonly used "tests" are inappropriate and give contradictory results that may mislead future research. The chemistry explaining EO antioxidant activity is discussed along with an analysis of the potential in food protection. Literature methods to assess EOs' antioxidant performance are critically reviewed. PMID:24156356

Assuming that a state is passive for an observer travelling along certain (essential) worldlines, we show that this state is invariant under the isometry group, is a KMS-state for the observer at a temperature uniquely determined by the structure constants of the Lie algebra involved and fulfills (a variant of) the Reeh-Schlieder property. Also the modular objects associated to such a state and the observable algebra of an observer are computed and a version of weak locality is examined.

Medical Treatment of Essential Tremor  

PubMed Central

Essential tremor (ET) is the most common pathological tremor characterized by upper limb action—postural tremor (PT)/kinetic tremor (KT). There are no specific neuropathological or biochemical abnormalities in ET. The disability is consequent to amplitude of KT, which may remain mild without handicap or may become disabling. The most effective drugs for sustained tremor control are propranolol and primidone. Symptomatic drug treatment must be individualized depending on the circumstances that provoke the tremor-related disability. Broad guidelines for treatment are discussed in this review. Patients may be treated intermittently only on stressful occasions with propranolol, clonazepam, or primidone monotherapy, or an alcoholic drink.

[Changes in the composition of the essential oil in stored marjoram].  

PubMed

The composition of volatile components of the essential oil of marjoram plants (Majorana hortensis M.) and its stability during storage were studied by capillary gas chromatography and gas chromatography/mass spectrometry. Storage in the dark for 1 year was associated with insignificant changes in the composition of the essential oil, and its organoleptic characteristics remained largely unaffected. Storage in the light produced considerable changes in the composition of the oil, due to chemical transformation of terpenoids. PMID:12754836

Chitosan beads loaded with essential oils in cosmetic formulations.  

PubMed

The aim of this work is to evaluate the stability and release of chitosan beads loaded with volatile molecules of Mentha piperita essential oil (E.O.) in a cosmetic formulation. The ability of the beads to quickly release Mentha piperita E.O. during use of a cosmetic formulation such as a bath foam is also assessed. The chitosan beads were produced with three different chitosan dispersions gelled with two different gelling solutions: (a) a 10% solution of sodium hydroxide (NaOH) and (b) a 4% solution of sodium tripolyphosphate (TPP). A few properties of six bead samples loaded with Mentha piperita E.O. are assessed. The properties are morphology, size, swelling ability, encapsulation efficiency, stability in time, and fast release of Mentha piperita E.O. during the use phase of the cosmetic formulation.

[Suggestions for buying medical equipment in hospitals].  

PubMed

TO THE EDITOR: Both in Greece and in other European countries there are plans to buy more medical equipment. If the whole procedure is not effective, it may result to a large deficit in the hospital budget. The total hospital deficit now in Greece is about 2.5 billion euros. It is suggested that in every hospital, the Authorized Committee for Medical Equipment Purchasing, should include the following: One Director of a Medical Department related to the equipment to be bought and another Director of a Medical Department, unrelated. One accountant. One legal advisor specialized in hospital affairs. One economical advisor specialized in banking who will be able to suggest leasing or other means of financing the purchase of the relevant equipment. A cost accounting analysis described by a detailed report, should be provided to secure that the equipment to be bought should be cost-effective and leaving a reasonable surplus after not more than 10 years from the time it is installed. Finally, the possibility of using one expensive equipment to cover the needs of more than one hospitals either by moving the equipment (i.e. the PET/CT camera by a large vehicle) or by transferring the patients to a central hospital, may be provided by the above Authorized Committee.

Subsea equipment marriage is top ROV priority  

SciTech Connect

Interfacing subsea equipment with remotely operated vehicles (ROV's) and the further development of arctic-class units are the primary challenges facing manufacturers. Worldwide use of the ROV for drilling support has exploded during this decade as oil companies continue their search in deeper waters. If the unmanned vehicles are to become an even more integral tool of the oilman, experts say they must be able to perform more complex tasks. The evolution of more multi-purpose ROVs, however, hinges on the redesigning of subsea equipment. The severe limitations on subsea support (by ROVs) is the obsolete design associated with the subsea equipment itself. These limitations are discussed.

Incidents of chemical reactions in cell equipment  

SciTech Connect

Strongly exothermic reactions can occur between equipment structural components and process gases under certain accident conditions in the diffusion enrichment cascades. This paper describes the conditions required for initiation of these reactions, and describes the range of such reactions experienced over nearly 50 years of equipment operation in the US uranium enrichment program. Factors are cited which can promote or limit the destructive extent of these reactions, and process operations are described which are designed to control the reactions to minimize equipment damage, downtime, and the possibility of material releases.

Stabilizing brokerage  

PubMed Central

A variety of social and economic arrangements exist to facilitate the exchange of goods, services, and information over gaps in social structure. Each of these arrangements bears some relationship to the idea of brokerage, but this brokerage is rarely like the pure and formal economic intermediation seen in some modern markets. Indeed, for reasons illuminated by existing sociological and economic models, brokerage is a fragile relationship. In this paper, we review the causes of instability in brokerage and identify three social mechanisms that can stabilize fragile brokerage relationships: social isolation, broker capture, and organizational grafting. Each of these mechanisms rests on the emergence or existence of supporting institutions. We suggest that organizational grafting may be the most stable and effective resolution to the tensions inherent in brokerage, but it is also the most institutionally demanding. PMID:22198763

Silas Weir Mitchell's essential tremor.  

PubMed

Silas Weir Mitchell (1829-1914) is recognized as an important American neurologist. Biographers refer in brief to a tremor. The objective of this review was to characterize Mitchell's tremor using handwriting samples, to examine handwriting samples of family members to determine whether this tremor was familial, and study Mitchell's allusions to tremor in personal, scientific, and fictional writings. Primary sources were the Papers of S. Weir Mitchell, College of Physicians of Philadelphia, and Mitchell's scientific and fictional writings. Mitchell's early handwriting was tremor-free yet, by 1873, the writing was tremulous. Handwriting in the 1880s and 1890s shows clear oscillations of moderate-amplitude. By the first decade of the 20th century, his handwriting was virtually illegible. Letters written by two siblings, his mother, and maternal grandfather also reveal tremor. Tremor was not prominent in Mitchell's personal or scientific writings and Mitchell referred to tremor in only 4 of 27 fictional writings. In conclusion, Mitchell had a familial action tremor that began when he was in his early 40's and worsened considerably with age. The likely diagnosis was essential tremor. Curiously, Mitchell rarely alluded to tremor in personal writings and tremor was not prominently featured in his scientific or fictional works. PMID:17516486

Essentially nonoscillatory postprocessing filtering methods  

NASA Technical Reports Server (NTRS)

High order accurate centered flux approximations used in the computation of numerical solutions to nonlinear partial differential equations produce large oscillations in regions of sharp transitions. Here, we present a new class of filtering methods denoted by Essentially Nonoscillatory Least Squares (ENOLS), which constructs an upgraded filtered solution that is close to the physically correct weak solution of the original evolution equation. Our method relies on the evaluation of a least squares polynomial approximation to oscillatory data using a set of points which is determined via the ENO network. Numerical results are given in one and two space dimensions for both scalar and systems of hyperbolic conservation laws. Computational running time, efficiency, and robustness of method are illustrated in various examples such as Riemann initial data for both Burgers' and Euler's equations of gas dynamics. In all standard cases, the filtered solution appears to converge numerically to the correct solution of the original problem. Some interesting results based on nonstandard central difference schemes, which exactly preserve entropy, and have been recently shown generally not to be weakly convergent to a solution of the conservation law, are also obtained using our filters.

Essential interventions for child health  

PubMed Central

Child health is a growing concern at the global level, as infectious diseases and preventable conditions claim hundreds of lives of children under the age of five in low-income countries. Approximately 7.6 million children under five years of age died in 2011, calculating to about 19 000 children each day and almost 800 every hour. About 80 percent of the world’s under-five deaths in 2011 occurred in only 25 countries, and about half in only five countries: India, Nigeria, Democratic Republic of the Congo, Pakistan and China. The implications and burden of such statistics are huge and will have dire consequences if they are not corrected promptly. This paper reviews essential interventions for improving child health, which if implemented properly and according to guidelines have been found to improve child health outcomes, as well as reduce morbidity and mortality rates. It also includes caregivers and delivery strategies for each intervention. Interventions that have been associated with a decrease in mortality and disease rates include exclusive breastfeeding, complementary feeding strategies, routine immunizations and vaccinations for children, preventative zinc supplementation in children, and vitamin A supplementation in vitamin A deficient populations.

US Department of Energy's Efforts in Intelligent Processing Equipment  

NASA Technical Reports Server (NTRS)

The Department of Energy (DOE) uses intelligent processing equipment (IPE) technologies to conduct research and development and manufacturing for energy and nuclear weapons programs. This paper highlights several significant IPE efforts underway in DOE. IPE technologies are essential to the accomplishment of DOE's missions, because of the need for small lot production, precision, and accuracy in manufacturing, hazardous waste management, and protection of the environment and the safety and health of the workforce and public. Applications of IPE technologies include environmental remediation and waste handling, advanced manufacturing, and automation of tasks carried out in hazardous areas. DOE laboratories have several key programs that integrate robotics, sensor, and control technologies. These programs embody a considerable technical capability that also may be used to enhance U.S. industrial competitiveness. DOE encourages closer cooperation with U.S. industrial partners based on mutual benefits. This paper briefly describes technology transfer mechanisms available for industrial involvement.

Coaxial Control of Injection Equipments by Master Slave Scheme for a Parallel Speed Control System  

NASA Astrophysics Data System (ADS)

In this paper, a novel master-slave system is proposed for the coaxial control of injection equipments constituted with two or more drive axes. Each drive axis is basically controlled by the PI speed control system and a new master-slave scheme is introduced for the tracking control of the angles of the two parallel subsystems. The adequacy of the scheme is supported by the controllability of the system. Easiness of the parameter tuning of the controller is clarified from the viewpoint of stability, tracking property, and disturbance rejection property. Simulation result and experimental result are also given for the test 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.
