Time Course of Sensitivity of Golden Hamsters to Melatonin Injections Throughout the Day1 (1983)

Twenty-four groups of adult male golden hamsters, housed on 14 h of light, 14L:10D, received daily injections of melatonin, each at a different hour of the day. Injections (15 micrograms melatonin/0.1 ml ethanol:saline, 1:10, s.c.) persisted for 27 weeks. At the beginning of this investigation and every 2-4 weeks thereafter, laparotomies were performed on a few animals of each group and the testes measured to assess the efficacy of the melatonin injections in causing testicular regression. Two periods of melatonin sensitivity were identified. The first was brief, of 1-h duration, immediately prior to lights on (0500-0600 h). The second period extended for 6 h throughout late afternoon and early evening (1500-2100 h; lights out 2000 h). Regression was complete in all these groups except that injected at 1500 h in which the testes regressed to only 950 mg before recrudescence occurred. In all other affected groups, testes regressed to less than 400 mg. In those groups where melatonin did not cause full testicular regression, daily injections resulted in partial regression, usually to approximately 2000 mg prior to regrowth.
[The probiotic correction of microecological and immune disorders in gastroduodenal pathology in children]. (1996)

The state of microbiocenosis was studied and the level of immunoglobulins was determined in the gastric juice and feces of children with chronic diseases of the digestive system. In 20% of patients an increase in the contamination of the gastric biotope with opportunistic microflora was established. The isolation rate of Helicobacter pylori was 56%. The detection of H. pylori was found to be accompanied by the aggravation of the form and course of gastritis. In cases of Helicobacter-associated pathology the deficiency of Lactobacillus sp. in the stomach was established, which was accompanied by their deficiency and absence in feces. The study also revealed a decrease in the population level of Bifidobacterium sp. with a simultaneous increase in the population of opportunistic enterobacteria and changes in the state of local immunity: the decreased level of SIgA in most samples and the decreased level of IgG in the presence of H. pylori. The correction of microecological and immune disturbances with probiotic preparations, containing bifidobacteria (bifidumbacterin-forte) and lactobacilli, yielded good results.
Comparative bactericidal effects of azlocillin and ticarcillin against Pseudomonas aeruginosa (1980)

Azlocillin was relatively ineffective against actively growing cultures of Pseudomonas aeruginosa in tests of bacteriolytic and bactericidal activity in which ticarcillin demonstrated pronounced bactericidal effects over a wide range of concentrations. Microscopic observation showed that azlocillin generally induced the formation of filamentous cells of P. aeruginosa which lysed only slowly, but ticarcillin caused the production of spheroplasts and subsequent rapid lysis. During the course of the bactericidal tests, azlocillin was inactivated, presumably by the beta-lactamase produced by P. aeruginosa, and the filamentous cells resumed normal cell division and growth. In contrast, there was no loss of ticarcillin activity, and there was no evidence of resumption of growth of P. aeruginosa in the presence of ticarcillin. These results suggest that the different bactericidal effects demonstrated by azlocillin and ticarcillin against P. aeruginosa are related primarily to dose-related differences in inhibition of cell wall synthesis and secondarily to the instability of azlocillin to pseudomonal beta-lactamase.
Record Linkage (2001)

Abstract Record linkage is the methodology of identifying pairs of records associated with entities from two or more files. Entities may be persons or businesses. Record linkage also refers to finding duplicates within files. Sometimes, records are linked using unique identification numbers such as a Social Security Number. Typically, non‐unique identifiers such as names, addresses, and other information are used. These methods of record linkage are called exact matching. Methods for exact matching may be based on ad hoc rules that may be applicable in a limited number of situations. Methods may also be based on a formal mathematical model as discussed in this article.
The Holy Trinity with Saints John the Baptist, Mary Magdalen, Tobias and Raphael by Botticelli and assistants: A technical examination for attribution (1997)

Abstract The “Holy Trinity with Saints John the Baptist, Mary Magdalen, Tobias and Raphael” has been the subject of controversy regarding both its provenance and its attribution as a workshop product. This article outlines critical opinions and examines the extent to which an analysis of the materials, technique and condition allow a reassessment of these points of view. It is suggested that the division of labour is likely to be confined to the insertion of the cherubs. A major revision in the composition is also discussed within the context of the practical processes involved in fulfilling the patron's requirements for this large altarpiece commission.
<u>The Search for a Whole Life: II</u>Turning Toward the Professions (1974)

say frightening/' President Brewster explains, not because I think there are too many doctors and lawyers, but because there are too many applicants and too few places. Students trying to get through the bottleneck of admissions have become so preprofessional in a grim and frenetic way that the value of a free-floating exploratory experience is being squeezed out/' Such diverse Yale entities as campus radicals, visiting alumni, professors, and administrators share Brewster's view. They regard grim professionalism as a threat to the ideal college experience of adventurous academic and extracurricular life.
<b>STUDIES ON SOLVENT EXTRACTION OF FREE HYDROGEN CYANIDE FROM RIVER WATER</b> (2007)

A method for free and strongly complexed cyanide measurement in river water was developed. Recovery tests from solution with and without river water, using various solvent combinations and background control were investigated to obtain an accurate and precise extraction method for the measurement of hydrogen cyanide in Kaduna River, Nigeria. The method enhanced the determination of undissociated hydrogen cyanide and the equilibria between hydrogen cyanide, cyanide ion and complex cyanides. A small portion of the hydrogen cyanide was extracted by equilibrating the sample with methylchloroform (1,1,1-trichloroethane), methanol, hexane and 2-octanol inclusions, respectively, in the solvent matrix with 2.5 M NaOH. The extracted hydrogen cyanide is transferred into tetrasodium pyrophosphate solution and determined colorimetrically. A total cyanide concentration of 0.03 mg/L in the river water and 0.40 mg/L in an effluent water sample, respectively, were obtained by the proposed method compared to 0.020 and 0.45 mg/L from the established diffusion method. The proposed method was sensitive and reproducible in the range of 0 to 5 mgL-1 of hydrogen cyanide with detectable limit of about 0.01 mgL-1.

Methods for Measuring the Characteristics of Movements of Motor-Impaired Children (1990)

An economical video-based movement monitoring system has been developed as a tool for the non-contact monitoring of the movement patterns of persons with impaired motor function. Measurements of movements in a plane normal to the camera may be made at a rate of 50 observations per second, with a positional resolution of 0.5 min in a field of view 675 mm wide by 500 mm deep. Trials were conducted on six children with cerebral palsy and 15 age-matched children with no motor impairment. Observations were made of the trajectories of a wrist-mounted marker while subjects performed prompted switch-activation tasks. Data were analyzed in an attempt to identify characteristics that would allow subjects' intentional movements to be distinguished and recognized despite the presence of involuntary movements. Regression analysis identified two significant trajectory characteristics, the average lateral position and average direction, that were suitable for predicting which of two switches a subject was intending to activate. Intended actions were predicted with an average certainty of 88.5% for the children with cerebral palsy and 98.7% for those with no obvious impairment. More sophisticated measures may be required when attempting to recognize a larger set of unprompted switch-activation movements in the presence of other voluntary or involuntary movements. Selected combinations of movement attributes should enable deliberate actions to be more readily and accurately recognized and used for control purposes.
Market Potential of Oriented Strand Board (OSB) & Laminated OSB (Lami-OSB) in Asia Pacific (2001)

Formaldehyde (HCHO) produces DNA-protein crosslinks both in vitro and in vivo. Simian virus 40 (SV40) chromosomes that have been fixed by prolonged incubation with HCHO either in vitro or in vivo (within SV40-infected cells) can be converted to nearly protein-free DNA by limit-digestion with Pronase in the presence of NaDodSO4. The remaining Pronase-resistant DNA-peptide adducts retard the DNA upon gel electrophoresis, allowing resolution of free and crosslink-containing DNA. Though efficiently crosslinking histones to DNA within nucleosomes both in vitro and in vivo, HCHO does not crosslink either purified lac repressor to lac operator-containing DNA or an (A + T)-DNA-binding protein (alpha-protein) to its cognate DNA in vitro. Furthermore, a protein that does not bind to DNA, such as serum albumin, is not crosslinked to DNA by HCHO even at extremely high protein concentrations. These properties of HCHO as a DNA-protein crosslinker are used to probe the distribution of nucleosomes in vivo. We show that there are no HCHO-crosslinkable DNA-protein contacts in a subset of SV40 chromosomes in vivo within a 325-base-pair stretch that spans the "exposed" (nuclease-hypersensitive) region of the SV40 chromosome. This replication origin-proximal region has been found previously to lack nucleosomes in a subset of isolated SV40 chromosomes. We discuss other applications of the HCHO technique, including the possibility of obtaining base-resolution in vivo nucleosome "footprints."

OPERATING STRATEGY FOR MAINTAINING AN OPTIMUM POWER DISTRIBUTION THROUGHOUT LIFE (1964)

A method of operation developed for maintaining a minimum power peaking factor throughout the operating cycle of a power reactor is described. The basic operating principle for peaking factor minimization is presented, and its use in the design phase to compare and set design parameters and in the operational phase to establish control rod patterns is outlined. The method will (hopefully) increase the power density in the Big Rock Point Reactor. (D.C.W.)
Post‐transcriptional regulation of the transferrin receptor and 4F2 antigen heavy chain mRNA during growth activation of spleen cells (1991)

The expression of several cell surface proteins including the transferrin receptor and 4F2 antigen is induced when quiescent cells are activated and proliferate. We have studied this induction in mouse spleen cells after stimulation with 4 beta-phorbol 12-myristate 13-acetate (PMA), the Ca(2+)-ionophore, ionomycin and recombinant interleukin-2 (IL-2). The 4F2 antigen heavy chain and transferrin receptor mRNA were barely detectable in resting cells, but increased 60-fold within 4 h of growth stimulation. The corresponding proteins became measurable at the cell surface after 6 h, prior to the S phase. In run-on transcription assays the transferrin receptor gene was transcribed to almost the same extent in resting and growth-stimulated cell populations and the 4F2 antigen heavy chain gene was induced fivefold. This suggests that post-transcriptional control mechanisms are mainly responsible for the accumulation of the respective mRNA at the onset of cell proliferation. In the case of the transferrin receptor, the induction correlated with an activation of the mRNA-binding iron-regulatory factor which is known to increase the stability of the cytoplasmic transferrin receptor mRNA.
Interactive Tactile Maps for Blind People using Smartphones? Integrated Cameras (2014)

Tactile maps may support blind persons in orientation and understanding geographical relations, but their availability is still very limited. However, recent technologies such as 3D printers allow to autonomously print individual tactile maps which can be linked with interactive applications. Besides geographical depictions, textual annotation of maps is crucial. However, this often adds much complexity to tactile maps. To limit tactile complexity, interactive approaches may help to complement maps by the auditive modality. The presented approach integrates barcodes into tactile maps to allow their detection by standard smartphones' cameras. Automatically, more detailed map data is obtained to auditively support the exploration of the tactile map. Our experimental implementation shows the principal feasibility and provides the basis of ongoing comprehensive user studies.
The Performance of the U.S. Market for Independent Electricity Generation (1996)

We examine recent evidence on the economic performance of the U.S. independent electricity generation market. A sample of power purchase contracts for 26 independent power facilities is used as the basis of this assessment. The contracts were executed in various years between 1987-94. We describe qualitative features of the contracts, including dispatchability and allocation of fuel price risk. We standardize the price formulas of the contract sample and conduct a simple statistical analysis. Because of residual price variation and an indication that buyer willingness-to-pay is highly correlated with price, we conclude that bulk power sold by independent power producers is a heterogeneous product, and evidence for competition in market prices is weak.
Comparative Study on Monotherapy with Sustained-Release Diltiazem 300 mg and Enalapril 20 mg in Mild to Moderate Arterial Hypertension (1990)

The antihypertensive efficacy of sustained-release diltiazem 300 mg at a single daily dose was evaluated and compared to that of enalapril 20 mg at a single daily dose, and to a combination therapy of enalapril 20 mg with sustained-release diltiazem 300 mg in patients with mild to moderate arterial hypertension (supine diastolic blood pressure between 95 and 115 mm Hg). After a washout period and a placebo period, each lasting 2 weeks, 96 patients were randomized in this double-blind study to three parallel groups that were treated for 28 days. In the groups treated with diltiazem, enalapril, or the combination of both, the drop in arterial blood pressure was 20, 11, and 19 mm Hg for supine diastolic blood pressure (supine DBP): 18, 12, and 19 mm Hg for standing diastolic blood pressure (standing DBP); 22, 20, and 23 mm Hg for supine systolic blood pressure (supine SBP); and 21, 19, and 24 mm Hg for standing systolic blood pressure (standing SBP), respectively. The reduction in DBP was significantly more pronounced in the group treated with sustained-release diltiazem 300 mg than in the group treated with enalapril 20 mg. Cardiac tolerance was good for patients treated with sustained-release diltiazem 300 mg alone or the combination therapy: no orthostatic hypotension or lengthening of the PR interval in the electrocardiogram was observed. Although side effects of sustained-release diltiazem 300 mg occurred more frequently, they were not severe and disappeared immediately when treatment was suspended.
Utilization based duty cycle tuning MAC protocol for wireless sensor networks (2005)

In this paper, we propose U-MAC, a medium access control protocol designed for wireless sensor networks. Nowadays, wireless sensor network are formed by a great quantity of sensor nodes, which are generally battery-powered and may not recharge easily. Consequently, how to prolong the lifetime of the nodes is an important issue while designing a MAC protocol. However, lowering the energy consumption may result in higher latency. Addressing on such tradeoff, U-MAC balances the tradeoff by utilization based tuning of duty cycle and selective sleeping after transmission. The experiment results show that our proposed U-MAC saves energy about 43% and reduce latency by 65% from S-MAC in a chain topology. In the cross topology, U-MAC also achieves 32% energy saving and 45% latency reduction from S-MAC.

A synthetic workload model for a distributed system file server (1991)

The accuracy of the results of any performance study depends largely on the quality of the workload model driving it. Not surprisingly then, workload modelling is an area of great interest to those involved in the study of computer system performance. While a significant amount of research has focussed on the modelling of workloads in a centralized computer system, little has been done in the context of distributed systems. The goal of this research was to model the workload of a distributed system file server in a UNIX/NFS environment. The resulting model is distribution-driven and generates workload components in real time. It runs externally to the system it drives, thus eliminating any interference at the server. The model was validated for different workload intensities to ensure that it provides the flexibility to vary the workload intensity without loss of accuracy.
Identification and Characterization of an Archaeon-Specific Riboflavin Kinase (2008)

The riboflavin kinase in Methanocaldococcus jannaschii has been identified as the product of the MJ0056 gene. Recombinant expression of the MJ0056 gene in Escherichia coli led to a large increase in the amount of flavin mononucleotide (FMN) in the E. coli cell extract. The unexpected features of the purified recombinant enzyme were its use of CTP as the phosphoryl donor and the absence of a requirement for added metal ion to catalyze the formation of FMN. Identification of this riboflavin kinase fills another gap in the archaeal flavin biosynthetic pathway. Some divalent metals were found to be potent inhibitors of the reaction. The enzyme represents a unique CTP-dependent family of kinases.
Diversity dual‐band planar inverted‐F antenna for WLAN operation (2003)

Abstract A printed diversity dual‐band planar inverted‐F antenna (PIFA) mounted vertically at the edge of a PCMCIA network card (such that the protruded portion of the network card from the housing of the laptop has a minimum length) for WLAN operation in the 2.4‐GHz band (2400–2484 MHz) and 5.2‐GHz band (5150–5350 MHz) is presented. The diversity antenna studied comprises two back‐to‐back stacked PIFAs and has a low profile of 10 mm to the network card. Across the two operating bands, the measured reflection coefficient S 11 and isolation S 21 are all less than −14 dB (1.5:1 VSWR) and −24 dB, respectively. In addition, the measured radiation patterns of the two stacked PIFAs in general cover complementary space regions, thereby making it possible for providing spatial diversity for WLAN operation. © 2003 Wiley Periodicals, Inc.

Transesophageal low-energy cardioversion in an animal model of life-threatening tachyarrhythmias. (1989)

The purpose of this study was to determine the feasibility and efficacy of terminating life-threatening ventricular tachyarrhythmia by low-energy synchronous or asynchronous shocks delivered through a transesophageal catheter that had both an anode and a cathode. Forty-three episodes of ventricular fibrillation or flutter (Vf or VF) were provoked by transesophageal asynchronous random shocks occurring during the vulnerable period of the ventricular cycle in seven dogs and seven pigs that were healthy adults. The 43 episodes of Vf or VF were terminated by the transesophageal technique. The defibrillation energy thresholds were 23.11 +/- 6.28 J (range, 5-30 J). Seven episodes of ventricular tachycardia (VT) with a cycle length of 360 msec or less (330 +/- 27 msec) were provoked by ventricular pacing stimuli during acute myocardial ischemia resulting from delayed resuscitation in two dogs and three pigs. Five of the seven VTs had a duration of 31 seconds or more, and they were all terminated by transesophageal synchronous shocks, the cardioversion thresholds being 1.71 +/- 2.25 J (range, 0.25-5 J). Fourteen episodes of idioventricular tachycardia (IVT) with a cycle length of 400 msec or more (445 +/- 33.5 msec) spontaneously occurred after the use of adrenaline and after defibrillation in four dogs and five pigs. We also succeeded in terminating seven episodes of IVT with a duration of 34 seconds or more by the same means of treating VT, although IVT is not an indication for cardioversion in the clinical setting.(ABSTRACT TRUNCATED AT 250 WORDS)
Prevalencia de parasitismo intestinal y situación nutricional en escolares y adolescentes de Tunja (2011)

Objective: To determine the prevalence of intestinal parasitism and nutritional status in children and adolescents aged 6 to 18 enrolled in public and private schools from urban Tunja, Colombia. Materials and methods: This is a prevalence study made in 507 schoolchildren of Tunja, included from February to December 2005. Fecal sample was taken; also social, demographic and anthropometric data. Tables of frequency and nutritional indicators were calculated by following the anthropometry WHO tables. Results: The prevalence of intestinal parasites was 89.7 %. Blastocistis hominis occurred in 67,9% of the children, Entamoeba histolytica / Entamoeba dispar in 8.66 %, Giardia intestinalis, 7.82 %; Trichuris trichiura, with 0.84 % and Fasciola hepatica, with 0.28 %. Hemoglobin showed normal average values for children and adolescents (Hb: 14.7 ±-0.82 g/dl and 15.45±1.18 g/dl), respectively. Chronic malnutrition was found in 21.6 % for boys and 34.3% for girls), 16.7 % of boys and 11.1 % of girls were overweight Conclusions: Given the current situation exist poliparasitism in children of Tunja, and indicators of acute and chronic malnutrition are higher than the national total. According to the law , must be protected and campaigns should be made to eradicate these two scourges.
