Detection of early pregnancy in domestic ruminants. (1987)

Tests for the detection of pregnancy early after insemination have not yet reached their full potential. Currently, the milk progesterone assay provides the earliest possible test, at an interval of one oestrous cycle after insemination, i.e. 17, 21 and 21 days in sheep, goats and cows respectively. This assay is pregnancy non-specific and rate of detection of pregnant animals is acceptable but less than desirable. Detection of activity of early pregnancy factor may develop into an excellent early test for many species, but the rosette inhibition test which is currently required has limited development and use. Pregnancy-specific protein B has been developed as a radioimmunoassay and is reliable under laboratory situations for ruminants. It can be used after 24 days of gestation in the cow. Application to field testing awaits development. Other pregnancy-associated or specific substances which are found in maternal body fluids might develop as pregnancy markers. Ultrasonic devices might provide very early detection in cattle but the expense of a test will limit application. All tests for pregnancy early after insemination have an inherent inaccuracy. Presence of an embryo at the time the test is applied will not assure pregnancy at the time of a confirmatory test, such as birth of live young or rectal examination in cows after 35 days of gestation. Therefore, no matter how early the test, a follow-up examination might be desirable in intensively managed herds or flocks. The animal industry is on the verge of new biotechnological approaches to reproductive management. The potential seems as great as the imagination.
Heat and Mass Transfer Analysis of Mine Exhaust Air Heat Exchanger (2013)

As a good energy resource, Mine exhaust air has an important value of recycling. In this paper, the heat and mass exchange mechanism and potential of the mine exhaust air heat exchanger (MEAHE) is mainly researched. The heat exchanger efficiency is affected by water and air temperature and flow in terms of double efficiency method. The result can provide the basis for the further determine the thermal calculation method for MEAHE, and lays the foundation for the mine comprehensive utilization of waste heat recovery system design.

INTERACTION BETWEEN THYROTROPHIN, CORTICOTROPHIN AND GROWTH HORMONE SECRETION IN MAN (1971)

SUMMARY Thyrotrophin (TSH) release in response to intravenous synthetic thyrotrophin releasing hormone (TRH) was unaltered by simultaneous corticotrophin (ACTH) and growth hormone secretion induced by hypoglycaemia or methylamphetamine in normal subjects. Secretion of growth hormone was the same whether or not TSH was secreted. While the increments in plasma corticosteroids and ACTH after methylamphetamine administration were not different whether TRH or a control injection was given, they rose more during insulin-induced hypoglycaemia when TRH was given as well. This could have been due to a slightly greater degree of stress after TRH + insulin than insulin alone. Overnight dexamethasone suppression of basal ACTH secretion did not alter the TSH response to TRH. Unlike the rat, there is no evidence suggesting competition between pituitary mechanisms involved in ACTH, growth hormone and TSH release in man.
Thermal Resistance of Egg‐Associated Epidemic Strains of Salmonella enteritidis (1991)

ABSTRACT Seventeen strains of Salmonella enteritidis isolated from patients and various implicated products from 5 egg‐associated outbreaks of salmonellosis were investigated for plasmid content, phage type and thermal resistance. D values obtained at 57.2 and 60°C in liquid whole egg for all strains were within ranges reported by previous investigators. Sublethal heat shock at 40°C for 2 hr or 48°C for 30 min increased thermotolerance 2‐ to 3‐fold. The induced thermotolerance decayed to control levels after 2–3 cycles of cell duplication at a lower temperature. Most strains contained a 39‐Mda plasmid and were phage type 8. No correlation was observed between thermotolerance and presence or absence of plasmid or phage type.
A BIOLOGICAL NAMED ENTITY RECOGNIZER (2002)

In this paper we describe a new named entity extraction system. Our system is based on a manually developed set of rules that rely heavily upon some crucial lexical information, linguistic constraints of English, and contextual information. This system achieves state of art results in the protein name detection task, which is what many of the current name extraction systems do. We discuss the need for detection of chemical names and show that we not only obtain a high degree of success in recognizing chemicals but that this task can help improve the precision of protein name detection as well. We use context and surrounding words for categorization of named entities and find the results obtained are encouraging.
Constitutive Expression of Pluripotency-Associated Genes in Mesodermal Progenitor Cells (MPCs) (2010)

MPCs express many pluripotency-associated genes and show a peculiar Oct-4 molecular circuit. Understanding this unique molecular mechanism could lead to identifying MPCs as feasible, long telomeres, target cells for reprogramming with no up-regulation of the p53 pathway. Furthermore MPCs are easily and inexpensively harvested from human bone marrow.
Does Inulin Reduce Postprandial Free Fatty Acid Rebound (2010)

High fibre diets are associated with reduced risk of type 2 diabetes mellitus (T2DM). This may be due to short-chain-fatty-acids (SCFA) influencing insulin resistance and secretion via changes in free-fatty-acids (FFA) and specific gut hormones. We aimed to determine the postprandial effects of inulin, a fermentable, soluble fibre in healthy subjects. Twelve fasted subjects were studied for 6 hours after either 80g high fructose corn syrup (HFCS), 56g HFCS plus 24g inulin, or 56g HFCS drinks using a randomized, cross-over design. SCFA were higher after inulin beginning at 4 hours. FFA were lower 4 hours after inulin than 56gHFCS. GLP-1 was higher 30 minutes after inulin than 56 and 80HFCS, while ghrelin was lower from 4-6 hours after inulin. The results support the hypothesis that inulin and SCFA generated from colonic fermentation of dietary fibre may improve insulin resistance and secretion via modulation of FFA and specific gut hormones.
Asphalt: Just More Portable (2014)

This article describes asphalt pellets, a portable, solid form of asphalt that is composed of asphalt and modifiers, additives, and fillers. They are shipped in small bags, one-ton “super sacks,” or in bulk and can be mixed with heated aggregate for conventional paving. They are also particularly useful when a job requires mixing on the paving site, e.g., pothole and utility cut patching. The author discusses the delivery system used for asphalt pellets, the formulation of the pellets, transportation and storage, mixing with aggregates, the use of pellets in remote locations, and the place of asphalt pellets in other environmentally-friendly (“green”) approaches, such as warm mix and recycling. The author concludes that asphalt pellets, while not appropriate for all paving situations, can be a useful alternative to traditional liquid asphalt moved by truck and barge. The article includes photographs of bulk asphalt pellets.
Investigations on the Recovery of Oil from Sandstones by Gas Drive (1936)

In the past few years a great deal of precise information has been obtainedabout the relation of natural gas to oil production. The improvement of ourunderstanding has been of great value, both in prolonging the life of wells andin providing a much needed technical background for the legal problem ofproration. But there are two principal aspects of the problem of production. Itis necessary to consider not only the energy available, in the form ofcompressed and dissolved gas and in the pressure of driving water, but also thetenacity with which the sandstone holds the oil. The amount of oil that eachsand condition will produce under given conditions of gas content should bedetermined. Hitherto the effect of the sand have been judged by a study of theflow of each well coupled with a procedure for extrapolating the productioncurve; but, as is well known to evaluation engineers, such production curvesare subject to changes that are not well understood, and often are affected byoutside disturbances. On the whole, the concept of "potential production" is vagueprincipally because the influence of the sand in production is not known beyondthe simple ideas of porosity and permeability. The permeability is a quantitythat has only inference value where mixtures of gas and oil or of gas, oil andwater are present. Excellent studies of the production of oil from reservoir packed withunconsolidated sand are available, but there studies treat largely ofsmall-scale analogies to a producing field, and the conclusions to he derivedfrom them are necessarily of a qualitative character because it is not known inwhat way these miniature oil fields resemble large ones.
Three-Dimensional Printing of Hollow-Struts-Packed Bioceramic Scaffolds for Bone Regeneration (2015)

Three-dimensional printing technologies have shown distinct advantages to create porous scaffolds with designed macropores for application in bone tissue engineering. However, until now, 3D-printed bioceramic scaffolds only possessing a single type of macropore have been reported. Generally, those scaffolds with a single type of macropore have relatively low porosity and pore surfaces, limited delivery of oxygen and nutrition to surviving cells, and new bone tissue formation in the center of the scaffolds. Therefore, in this work, we present a useful and facile method for preparing hollow-struts-packed (HSP) bioceramic scaffolds with designed macropores and multioriented hollow channels via a modified coaxial 3D printing strategy. The prepared HSP scaffolds combined high porosity and surface area with impressive mechanical strength. The unique hollow-struts structures of bioceramic scaffolds significantly improved cell attachment and proliferation and further promoted formation of new bone tissue in the center of the scaffolds, indicating that HSP ceramic scaffolds can be used for regeneration of large bone defects. In addition, the strategy can be used to prepare other HSP ceramic scaffolds, indicating a universal application for tissue engineering, mechanical engineering, catalysis, and environmental materials.
Socialized Word Embeddings (2017)

Word embeddings have attracted a lot of attention. On social media, each user’s language use can be significantly affected by the user’s friends. In this paper, we propose a socialized word embedding algorithm which can consider both user’s personal characteristics of language use and the user’s social relationship on social media. To incorporate personal characteristics, we propose to use a user vector to represent each user. Then for each user, the word embeddings are trained based on each user’s corpus by combining the global word vectors and local user vector. To incorporate social relationship, we add a regularization term to impose similarity between two friends. In this way, we can train the global word vectors and user vectors jointly. To demonstrate the effectiveness, we used the latest large-scale Yelp data to train our vectors, and designed several experiments to show how user vectors affect the results.
Construction of TnphoA gene fusions in Rhodobacter sphaeroides: isolation and characterization of a respiratory mutant unable to utilize dimethyl sulfoxide as a terminal electron acceptor during anaerobic growth in the dark on glucose (1989)

We have constructed a suicide vector, pU1800, containing the transposable element TnphoA (Tn5 IS50L::phoA), for the purpose of producing protein fusions in vivo between the Escherichia coli alkaline phosphatase (APase) and proteins of the facultative photoheterotroph, Rhodobacter sphaeroides. We introduced TnphoA into the genome of R. sphaeroides at a coupled conjugation-transposition frequency of approximately 1 x 10(-6). Fusions giving rise to APase expression, as judged by blue-colony pigmentation when exconjugants were plated on growth medium containing the chromogenic indicator 5-bromo-4-chloro-3-indolyl phosphate, were observed in about 1% of the exconjugants. Numerous, distinguishable mutant phenotypes have been generated by this method, including those which lack the ability to use dimethyl sulfoxide as a terminal electron acceptor during anaerobic respiration, as well as those which are photosynthetically incompetent or altered in pigment synthesis, and others that express resistance to chlorate. The growth and spectral characteristics of several of these mutants, as well as the localization and quantitation of subcellular APase activity under different physiological conditions, have been examined. The presence of TnphoA in the host genome has been confirmed for each mutant analyzed, and specifically tagged DNA fragments containing TnphoA have been identified and localized; cosmids containing R. sphaeroides genomic DNA capable of complementing individual mutants have also been isolated. The usefulness of this approach in studying gene activity in R. sphaeroides is discussed.
Short-Term impacts of pulsed electromagnetic field therapy in middle-aged university’s employees with non-specific low back pain: A pilot study (2019)

PEMT therapy may decrease pain, LBP disability, increase lumbar spine mobility, and improve HRQOL in middle-aged university's employees with nonspecific LBP.
Extracellular Acidosis Protects Ehrlich Ascites Tumor Cells and Rat Renal Cortex against Anoxic Injury (1974)

The present study indicates that extracellular acidosis protects Ehrlich ascites tumor cells and rat kidney cortex cells against injury from anoxia. Parameters measured included cell potassium, adenosine 5'-triphosphate, and uptake of vital dyes. Cells survived longer at a pH of 5.6 to 6.5 than at a pH of 7.4; pH 7.9 was most detrimental. These findings indicate that production of protons by anoxic cells may be a protective feedback mechanism.
High Speed TSV Filling Technology by using Molten Solder and Fabrication of Composite Solder as Filler Material (2012)

. 따라서 빠른 충진 시간을 갖는 충진 기술이 필요하며 빠른 충진 시간은 곧 생산성 증가로 연결되어 공정 비용을 낮추는 효과가 있다. 본 연구의 용융 솔더 충진 방법은 수초 이내의 짧은 시간내에 결함 없는 비아 충진이 가능한 방법이다. 웨이퍼 양단의 압력차를 이용하여 용융 솔더를 충진하는 방법으로 TSV 직경의 변화가 있더라도 압력만을 제어하여 빠른 충진이 가능하다는 장점을 가지고 있다. 또한 본 연구의 또 다른 이슈로 낮은 열팽창계수를 가지는 충진소재를 연구하였다. 기존의 TSV내에 충진된 Cu는 Si과의 열팽창계수 차이에 따라 Cu와 Si 간의 계면에 높은 Stress가 발생하게 된다. 이러한 Stress는 Cu의 Pop-up현상 및 Crack, Void 발생 등의 문제와 Si내의 Stress는 device의 성능저하를 일으키는 원인이 된다
STRUCTURE-INDUCED OPTICAL ANISOTROPY IN THIN FILMS. (1983)

Evaluation of real-time PCR and conventional diagnostic methods for the detection of Clostridium difficile-associated diarrhoea in a prospective multicentre study (2006)

In this prospective multicentre study, an enzyme-linked fluorescent assay (VIDAS CDA2; bioMérieux), an enzyme-linked assay [Premier Toxins A and B (PTAB); Meridian] and an in-house real-time PCR amplifying the tcdB gene were compared with the cell cytotoxicity assay used as the 'gold standard' for diagnosis of Clostridium difficile-associated diarrhoea (CDAD). Faecal samples from patients with a request for C. difficile diagnosis and samples from patients with diarrhoea hospitalized for at least 72 h were collected for 3 consecutive months from four university medical centres in The Netherlands. In total, 547 faecal samples were obtained from 450 patients. Of 540 samples available for all of the assays, 84 (15.6 %) showed a positive result in one or more assays. The cell cytotoxicity assay was positive in 31 samples (5.7 %) from 28 patients. A diagnosis of CDAD was not considered by the physician in 5 (23.8 %) of 21 patients with CDAD who were hospitalized for at least 72 h. Compared with the cell cytotoxicity assay, the sensitivity of VIDAS, PTAB and PCR was 83.9, 96.8 and 87.1 %, respectively. The specificity of VIDAS, PTAB and PCR was 97.1, 94.3 and 96.5 %, respectively. The positive and negative predictive values for VIDAS, PTAB and PCR were 63.4 and 99.0 %, 50.9 and 99.8 %, and 60.0 and 99.2 %, respectively. Of 61 samples that were positive in one, two or three of the assays, 56 were available for discordance analysis. Discordance analysis was performed by culture of toxinogenic strains. The concordance of VIDAS, PTAB and PCR with culture was 53.6 % (30/56), 55.4 % (31/56) and 71.4 % (40/56), respectively. It was concluded that real-time PCR had the highest concordance with toxinogenic culture and is therefore the preferred method for diagnosing CDAD in faecal samples. It was also concluded that diagnosis of patients with diarrhoea who have been hospitalized for more than 72 h should focus mainly on the detection of C. difficile, irrespective of the physician's request.
Conclusion (2010)

Abstract This concluding chapter discusses the key insights of this research on the Philippine state’s international migration within the context of globalization. It characterizes developing forms of labor brokerage outside the Philippines, along with the alternative meanings of rights and membership offered by migrant workers’ groups such as Migrante International. It shows how migrant activists continually establish important visions of more impartial ways of being and belonging that are proved to be important aspects in today’s neoliberal global order.
GPCA method for fraud detection in mobile communication networks (2006)

To improve the fraud detection accuracy by SVM (support vector machine), a feature extraction method named GPCA based on IG (information gain) and PCA (principal component analysis) is proposed. It analyzes the data on CDR (call detail record), customer information, paying and arrear information etc in mobile communication networks, and then the data can be used by the classifier SVM to build the fraud detection model and the user can predict the potential fraud customers. Despite of its simplicity, GPCA outperforms some of the most popular feature extraction methods such as BS (bivariate statistics), IG and PCA in predicting accuracy and training time. To get the higher predicting accuracy, a binary SVM using RBF (Radial Basis Function) kernel is used. The experiments show that the classifier with GPCA has fine predicting accuracy.
A reflector antenna corrected for spherical, coma, and chromatic aberrations (1971)

Characterization of polymer surfaces and polymer–metal interfaces by static secondary ion mass spectrometry (1992)

Abstract The applicability of Time‐of‐Flight SIMS (TOFSIMS) to the study of adhesion phenomena is discussed. The technique is especially powerful for the study of interactions at polymer–metal interfaces. This is demonstrated by a number of examples of TOFSIMS analysis of polymer surfaces, metal pretreatments and paint–metal interfaces of materials used in the automotive industry. The TOFSIMS high‐resolution spectrum of a film of Nylon‐6® is interpreted in some detail. The metal pretreatments that are discussed are by functional silanes. Thin organic films deposited on metals by plasma polymerization of silanes have also been analyzed. It is demonstrated that such films can be characterized by TOFSIMS. In several cases surface analyses by XPS and AES were also carried out in order to illustrate the complementary information that can be obtained by the application of these three major surface analysis techniques. The analysis of the paint–metal interfaces by TOFSIMS allows conclusions to be drawn about the state of cure of the paint and about preferential segregation of low‐molecular‐weight paint constituents to the metal surface.

Age- and Hormone-Dependent Ganglioside Patterns of Rat Hepatocytes in Primary Culture (1985)

Using an improved procedure for the quantitative extraction of all glycolipids from small tissue samples the hepatic ganglioside pattern of rats was analysed during development. While this parameter remained fairly constant in adult animals, hepatocytes in primary culture showed drastic changes both in content and relative distribution among the various ganglioside species. The content of lipid-bound sialic acid increased several-fold during 6 days in monolayer and the pattern changed in favour of the higher sialylated forms. Dexamethasone delayed this transition and enhanced the content of GD1a and GM1 relative to GM3. The ganglioside content was also dependent on the density of hepatocytes in the primary culture. If the cell density was insufficient for formation of a confluent monolayer, higher ganglioside-sialic acid contents were found and the relative amount of GD3 increased after 3-4 days. These results support the notion that gangliosides are involved in cellular differentiation and cell-cell contact.
