New data on long term stabilization of polyethylene for telecommunication wire insulation (1983)

Abstract : Medium density polyethylene is widely used for the insulation of telecommunication wires. A lifetime of 40-50 years is generally desired. Thus the stabilization of the polyethylene in contact with copper is of prime importance. In this paper new data pertaining to the long term heat stabilization are presented. The loss of stabilizers as a function of time is examined and aging data on actual wires are shown. There is evidence that polyethylene stabilized with a combination of a sterically hinderd phenolic antioxidant (pentaerythrityl tetrakis (3.5-di-t-butyl-4-hydroxyphenyl propionate)) and a copper deactivator (N, N'-bis (beta-3.5-di-t-butyl-4-hydroxyphenyl-propiono) hydrazide) has good chances of reaching the expected lifetime.

Introduction of a Streptococcus cremoris plasmid in Bacillus subtilis (1983)

Streptococcus cremoris Wg2 plasmid pWV01 was introduced in Bacillus subtilis by protoplast transformation. The yield of pWV01 isolated from B. subtilis was low. pWV01 contains a unique site for the restriction endonuclease MboI.
Establishment by enzyme-linked immunosorbent assay of seronegative range for herpes simplex virus and cytomegalovirus antibodies and evaluation of heterologous responses to live varicella vaccine (1988)

Cord serum samples treated with staphylococcus protein A and an immune affinity column to remove immunoglobulin G were used to establish a seronegative range for herpes simplex virus and cytomegalovirus. No seroconversions or increased heterologous antibody levels to herpes simplex virus or cytomegalovirus were found in live varicella vaccine recipients.
A TARGET FOR CRITICS (1934)

Surprise at the methods followed and vigorous dissent from the conclusions reached are greeting the publication of the Thorndike study of the possibility of predicting vocational success. The subjoined review by Dr. Paterson criticizes the investigators for failure in so elementary a matter as the establishing of adequate criteria of vocational success. From across the sea comes a review of the sort commonly characterized as “devastating.” Written by Angus Macrae of the British National Institute of Industrial Psychology, published in the organ of the Institute , The Human Factor, and here reprinted by permission, the article points out—we quote from its own introduction—that the methods used in the Thorndike experiment “are a travesty of scientific vocational guidance.” It adds: “The failure of such methods was to be expected; but it is quite unjustifiable to argue from their failure to the uselessness of vocational guidance in general.” Dr. Paterson agrees. His review precedes that of Mr. Macrae.
Femtosecond thin disk laser oscillator with pulse energy beyond the 10-microjoule level (2008)

We report on a passively mode-locked Yb:YAG thin disk laser oscillator that generates 11.3-microJ pulses without the use of any additional external amplification. A repetition rate of 4 MHz is obtained using a 23.4-m-long multiple-pass cavity that extends the resonator length to a total of 37 m. The nearly transform-limited pulses at 45 W of average output power have a duration of 791 fs with a 1.56-nm-broad spectrum centered at 1030 nm. The laser is operated in a helium atmosphere to eliminate the air nonlinearity inside the resonator that previously limited the pulse energy.
Level shifter embedded in drive circuits with amorphous silicon TFTs (2006)

A drive circuit embedded with a level shifter was fabricated with conventional a-Si:H thin-film transistor (TFT) process. Two cascaded bootstrapped inverters were fabricated for the level shifter. The proposed level shifter shifts an input signal to a high voltage, for example, from 5 to 30 V. The level shifter embedded driver with a-Si:H TFT operates well for the input 5-V start pulse and clocks, and the 4th output of the driver shows 30.3-V output. The level shifter is stable under operation even though there is a threshold voltage shift of a-Si:H TFT. The stability of the driver was also investigated.
Thermoelectrochemically Activated MoO[sub 2] Powder Electrode for Lithium Secondary Batteries (2009)

The high temperature lithiation behavior of the MoO2 electrode is examined, which is lithiated by one-electron reduction (by\naddition reaction) at room temperature. At elevated temperatures, this electrode is lithiated with four-electron reduction by addition\nand continued conversion reaction. As a result of four-electron reduction, the initial crystalline MoO2 phase is decomposed into a\nnanosized mixture of metallic Mo and Li2O, which is in turn converted to nanosized MoO2 upon forthcoming delithiation. An\ninteresting feature here is that as-generated nanosized MoO2 is now fully lithiated up to four-electron reduction even at room\ntemperature. This phenomenon is named thermoelectrochemical activation because the extension from one- to four-electron\nreduction is achieved by a simple charge–discharge cycling made at elevated temperatures. The thermoelectrochemically activated\nMoO2 electrode delivers a reversible specific capacity that is close to the theoretical four-electron capacity (838 mAh g−1) with\nan excellent cycle performance at room temperature.
Comparative Activity of Adenosine Deaminase Acting on RNA (ADARs) Isoforms for Correction of Genetic Code in Gene Therapy (2018)

The Khartoum connection (2005)

Analysis found no support to the suggestion that TUGSE with atypical cells represents the oral counterpart of lymphomatoid papulosis or predisposes the lesions for a hematolymphoid malignancy. Suggestions for radical therapeutic approach and long-term follow-up are probably unjustified, with no recurrences or malignancy recorded following conservative treatment alone for a period of up to 9 years of follow-up. Staining for CD30 and PCR for TCR gene rearrangement should be reserved only for rare cases with abundant large atypical cells and/or unusual clinical behavior.
Effect of microstructure on impact toughness of duplex and superduplex stainless steels (2009)

Purpose: of this paper is to study the effect of heat treatments and resulting changes in microstructure on mechanical properties, mainly impact toughness, of commercial 2205 duplex stainless steel and higher alloy superduplex 2507 grade. Design/methodology/approach: Both steels were submitted to ageing treatments in the temperature range of 500-900 °C with exposure time periods 6 minutes, 1 hour and 10 hours. Light microscope examinations, hardness measurements and impact toughness tests were performed in order to reveal microstructure and changes in mechanical properties. Findings: Obtained results confirm that high temperature service of duplex stainless steels should be avoided. Precipitations of secondary phases (mainly σ phase) strongly deteriorate mechanical properties of steels but some amounts of these phases could be acceptable in the microstructure depending upon the application of the steel. Research limitations/implications: Presence of secondary phases in duplex stainless steel microstructure can be very harmful for its corrosion resistance. This phenomenon is not considered in this study. Practical implications: The accidents during exploitation and errors in processing of duplex stainless steels can result in undesired temperature growth over 500°C. Such events brings question whether the steel can be still exploited or not. The aim of present study is to reveal the effect of thermal cycles on structural changes and mechanical properties of duplex stainless steel and establish the highest acceptable time-temperature conditions for safe operation of the steel. Originality/value: Information available in literature does not clearly indicate what amount of secondary phases existing in duplex stainless steel microstructure can be acceptable. The current study shows that duplex 2205 steel affected by thermal cycles and containing about 10% of sigma phase still exhibit acceptable mechanical properties.
Factors influencing stem cell differentiation into the hepatic lineage <i>in vitro</i> (2005)

A major area of research in transplantation medicine is the potential application of stem cells in liver regeneration. This would require well-defined and efficient protocols for directing the differentiation of stem cells into the hepatic lineage, followed by their selective purification and proliferation in vitro. The development of such protocols would reduce the likelihood of spontaneous differentiation of stem cells into divergent lineages upon transplantation, as well as reduce the risk of teratoma formation in the case of embryonic stem cells. Additionally, such protocols could provide useful in vitro models for studying hepatogenesis and liver metabolism. The development of pharmokinetic and cytotoxicity/genotoxicity screening tests for newly developed biomaterials and drugs, could also utilize protocols developed for the hepatic differentiation of stem cells. Hence, this review critically examines the various strategies that could be employed to direct the differentiation of stem cells into the hepatic lineage in vitro.
The Effects of Light Intensity and Spectral Quality on Growth and Shoot Initiation in Tobacco Callus (1975)

The effects of eight different narrow band-emitting fluorescent lamps (371-750 nm) and four commercial broad band-emitting fluorescent sources upon growth and shoot initiation in tobacco callus (Nicotiana tabacum var. Wisconsin 38) have been characterized. Wavelength and intensity are equally important parameters in determining morphogenic changes. Near ultraviolet light (371 nm) was found to stimulate (0.024 mw/cm(2)) or inhibit (above 0.15 mw/cm(2)) callus growth and shoot initiation, depending on the light intensity. Stimulation of growth and shoot production occurs also in blue light region, but at higher intensity than in the near ultraviolet. Red and far red light (up to 1.7 mw/cm(2)) do not appear to affect callus growth or stimulate shoot initiation. The enhancement of callus growth and the stimulation of shoot initiation are controlled by the same near ultraviolet-absorbing photoreceptor system present in a small enough concentration that it cannot be recognized in the absorption spectrum of the intact tissue. Carotenoids, porphyrins, and phytochrome associated with the high irradiance response do not appear to qualify as the photoreceptor. Flavonoids are possible candidates. Radiation emitted by fluorescent lamps outside the near visible region was determined, and we concluded that energy levels were not sufficient to affect the reported results. The spectral output of several commercial lamps in the visible and near visible regions is such that there could be different effects on growth and development of tissue cultures.
High-Speed Maskless Laser Patterning of Thin Films for Giant Microelectronics (1999)

Maskless patterning of indium tin oxide (ITO) thin films was studied using a diode pumped Q-switched Nd:YLF laser. The wavelength was systematically varied from infrared to ultraviolet to investigate the effect of different conditions for light absorption by the ITO film and the glass substrate. Electrically isolating lines could be etched at all wavelengths used. However, residue-free removal of the ITO film could be achieved only when the glass substrate was strongly absorbing the incoming laser light. In all other cases, i.e., strong light absorption by the film only, weak absorption by the film and transmission by the substrate, or strong absorption by the film but weak absorption by the substrate, a ripple-like morphology in the etched groove was produced due to incomplete material removal. In case of ITO films on fused quartz substrates, therefore, the ripple-like morphology in the etched groove was observed at all wavelengths used. The results are consistent with thermal vaporization as the mechanism for the material removal which was confirmed by the predictions of numerical computations for the laser-induced temperature rise.

Biomimetic Foams of High Mechanical Performance Based on Nanostructured Cell Walls Reinforced by Native Cellulose Nanofibrils (2008)

A bioinspired foam in which cellulose nanofibrils are used to reinforce cell walls (ca. 3 µm) is presented. The nanocomposite foams are prepared by a lyophilization technique and show composite structure at the cell-wall scale. The nanocellulosic network shows remarkable mechanical performance, expressed in much-improved modulus and yield strength compared with the neat starch foam.
Association between Estrogen Receptor-β Gene Polymorphisms and Ovulatory Dysfunctions in Patients with Menstrual Disorders (2001)

Estrogen plays a significant role in human ovulation. It acts as an important positive regulator of the preovulatory gonadotropin surge necessary to initiate the cascade of events leading to ovulation. The steroid hormone exerts its physiological responses through the estrogen receptor (ER), of which two subtypes, ERalpha and ERbeta, are known. ERbeta messenger ribonucleic acid occurs maximally in the ovaries and granulosa cells; thus, ERbeta may be essential for normal ovulation. In a recent gene knockout study, it has been shown that ERbeta gene null female mice develop normal reproductive tract and ovaries during pre- and neonatal periods, but have an abnormal frequency of spontaneous ovulation in adulthood. In the present case-control study, we explored the association of two recently described ERbeta gene polymorphisms, RSAI and ALUI, with ovulatory dysfunctions. The respective frequencies of these polymorphisms were significantly higher in patients than in controls (P= 0.009 and P= 0.059). The polymorphisms were significantly associated with ovulatory dysfunctions, especially in patients homozygous for the polymorphisms (P = 0.016 and P = 0.038, respectively). The compound homozygosity of the polymorphisms was seen only in patients (n = 5) and not controls (P = 0.009). The serum levels of LH, FSH, and progesterone were lower in the homozygous and compound homozygous than in the respective nonpolymorphic patients. All five compound homozygous patients had ovulatory dysfunctions with no etiological pathology. Our results suggest that ERbeta gene RSA:I and ALU:I polymorphisms may be associated with ovulatory defects in some patients, especially those with unknown causes.

Tumor and organ biochemical profiles determined in vivo following uptake of a combination of radiolabeled substrates: potential applications for PET. (1992)

This paper describes a method which generates an in vivo metabolic profile of tumors and organ tissues derived from the tissue uptake of a combination of radiotracers. Metabolic substrates labeled with carbon-11, a positron-emitting radionuclide (T1/2 = 20.4 min) have been used to probe tumor metabolism in vivo using positron emission tomography (PET). Carbon-11 labeled radiotracers which have been used include alpha-aminoisobutyric acid (AIB), 2-deoxy-D-glucose (2-DG), and thymidine (TdR). This paper reports data on the tissue distribution of carbon-14 labeled analogues of AIB, 2-DG, and TdR. Tissue distribution studies were carried out in normal male Copenhagen rats, in rats bearing Dunning R3327G or R3327H prostatic adenocarcinomas, and in tumor rats that have been treated with difluoromethylornithine and methylglyoxal-bisguanylhydrazone, or with diethylstilbestrol. A combination of the tissue distribution data of these radiolabeled agents is used to provide a metabolic description of the state of a tumor or tissue in vivo. This approach to defining a tissue's biochemical profile may be useful for the assessment and prediction of a therapeutic response, even at low tracer concentrations in a tumor, and may be useful in relating the biochemical characteristics of one tissue to that of another.
Managing UI pattern collections (2005)

A large number of user interface (UI) pattern collections have been developed by different researchers. This paper discusses the main requirements for a tool to be used by researchers and user interface designers that can manage a repository of possibly disparate pattern collections. An analysis of the main requirements and specifications for such a tool has been carried out. Pattern tools have been surveyed to identify the functionality they provide. A framework for a UI pattern management tool has been developed in the light of the analysis and the survey.
[Transmission electron microscopy of tegument and digestive tract of Schistosoma japonicum during long-term cultivation in vitro]. (1992)

The article reports the result of the observation on the ultrastructure of the tegument and digestive tract of Schistosoma japonicum schistosomula cultured 130 days in vitro in 841 medium, and the 42-day-old adults from infected animal cultured 23 days in 851 medium by transmission electron microscopy. The results showed that the ultrastructure of the tegument including sensory papillae and flame cells was normal. The matrix seemed to have no vacuolization. The surface of the esophagus was highly rugous. Many laminae and lipid droplets filled the lumen of the digestive tract and the tubules-like depressions from basal lamina were occurred. All these structures seemed to have less variation as compared with the prior authors' data from normal worms. It is considered that the above two media which we cesigned were suitable for the growth and development of the schistosomes due to the tegument and digestive tract maintained their metabolic function in the long-term cultivation in vitro. (Figs 1-10).
A 300V/&amp;#181;s monolithic voltage follower (1979)

An open-loop monolithic buffer with 90MHz bandwidth will be reported in this paper. Biasing of source and emitter followers insures accurate unit gain with 10mA load current. Quasi-quad FET layout provides matching and thermal gradient cancellation without sacrificing speed.
Importance of the Major Histocompatibility Complex (Swine Leukocyte Antigen) in Swine Health and Biomedical Research (2019)

In pigs, the major histocompatibility complex (MHC), or swine leukocyte antigen (SLA) complex, maps to <i>Sus scrofa</i> chromosome 7. It consists of three regions, the class I and class III regions mapping to 7p1.1 and the class II region mapping to 7q1.1. The swine MHC is divided by the centromere, which is unique among mammals studied to date. The SLA complexspans between 2.4 and 2.7 Mb, depending on haplotype, and encodes approximately 150 loci, with at least 120 genes predicted to be functional. Here we update the whole SLA complex based on the Sscrofa11.1 build and annotate the organization for all recognized SLA genes and their allelic sequences. We present SLA nomenclature and typing methods and discuss the expression of SLA proteins, as well as their role in antigen presentation and immune, disease, and vaccine responses. Finally, we explore the role of SLA genes in transplantation and xenotransplantation and their importance in swine biomedical models.
Jarisch – Herxheimer Reaction in a Patient with Disseminated Lyme Disease (2013)

A 61-year-old man presented with a 2 week history of intermittent fever, recurrent headaches, arthralgia's and a non-pruritic erythematous macular rash on his right lower abdomen. The patient underwent an uncomplicated lumbar puncture and was commenced on antibiotics for suspected early disseminated Lyme disease. Few hours after the first antibiotic dose he had abrupt onset of high fevers, chills, hypotension and tachycardia requiring fluid resuscitation and antipyretics. Jarisch-Herxheimer reaction (JHR) is a transient shock-like syndrome that typically follows initiation of antibiotics and is classically associated with penicillin treatment of syphilis. We discuss a patient of disseminated Lyme disease who developed JHR after commencing antibiotic therapy.
Volatile Organic Compounds in Small- and Medium-Sized Commercial Buildings in California (2011)

While small- and medium-sized commercial buildings (SMCBs) make up 96% of the commercial buildings in the U.S., serving a large variety of uses, little information is available on indoor air quality (IAQ) in SMCBs. This study investigated 37 SMCBs distributed across different sizes, ages, uses, and regions of California. We report indoor concentrations and whole building emission rates of a suite of 30 VOCs and aldehydes in these buildings. There was a considerable range in the concentrations for each of the contaminants, especially for formaldehyde, acetaldehyde, decamethylcyclopentasiloxane, d-limonene, 2-butoxyethanol, toluene, 2,2,4-trimethylpentanediol diisobutyrate, and diethylphthalate. The cause of higher concentrations in some building categories generally corresponded to expected sources, for example, chloroform was higher in restaurants and grocery stores, and formaldehyde was higher in retail stores and offices. Factor analysis suggests sources in SMCBs include automobile/traffic, cleaning products, occupant sources, wood products/coating, and plasticizers. The comparison to health guidelines showed that formaldehyde concentrations were above the chronic RELs required by the OEHHA (9 μg/m³) in 86% of the buildings. Data collected in this study begins to fill the knowledge gap for IAQ in SMCBs and helps us understand the indoor sources of VOCs to further improve indoor air quality in SMCBs.
