Authors: HACIHASANOĞLU ÇAKMAK Neziha , YARDİBİ Hasret
Published: May 2019

Hereditary diseases cause yield and economic loses. It is important to examine hereditary diseases at the molecular level and to remove diseases from the herd. In our study, it was aimed to determine allele frequencies of genes that cause bovine leukocyte adhesion deficiency, factor XI deficiency and complex vertebral malformation diseases in Holstein cattle. Blood samples were randomly taken from 300 Holstein cattle in different dairy farms in Kocaeli, Sakarya and Balıkesir provinces. Deoxyribonucleic acid samples were isolated from blood samples by using the standard ammonium acetate salt-out method. The target regions were amplified by polymerase chain reaction to determine the mutant alleles causing bovine leukocyte adhesion deficiency, factor XI deficiency and complex vertebral malformation. According to the nucleotide chromotograms of the samples subjected to bovine leukocyte adhesion deficiency analysis, it was determined that 4 out of 300 cattle were heterozygous and 296 were homozygous. Polymerase chain reaction procedure for factor XI deficiency disease was sufficient, while samples amplified by polymerase chain reaction for complex vertebral malformation disease were subjected to restriction particle length polymorphism. Factor XI deficiency and complex vertebral malformation disease genes were all homozygous normal.

Authors: Usta Hikmet Aysın , GÜVENÇ Gökçen , Savcı Vahide , Yalçın Murat
Published: May 2019

Nesfatin-1 has a role in appetite control and energy balance. The activity of the cholinergic system also is able to affect feeding behavior. Moreover, the central cholinergic system interacts with central nesfatinergic systems. The main goal of the study was to determine the effect of intracerebroventricular (icv) and intravenous (iv) administrated CDP-choline (0.5 ve 1 μmol; icv ve 250 mg / kg; iv) on levels of plasma nesfatin-1 in the homogeneous number of male and female fasted and the satiated Wistar albino rats. The polyethylene cannula was inserted into the carotid artery and jugular vein of the rats anesthetized with sevoflurane (2–4%/100% O2) to collect blood samples and to make iv injection, respectively. For icv treatment, the lateral ventricle of rats was cannulated with guide cannula. The basal levels of plasma nesfatin-1 in the satiated rats were higher than those observed in the fasted animals. While 0.5 and 1 μmol dose of icv and/or 250 mg/kg dose of iv injected CDP-choline increased the level of plasma nesfatin-1 in the satiated rats, plasma nesfatin-1 level of the fasted animals decreased after the same dose and route of CDP-choline injection. The current findings show that CDP-choline can influence the level of plasma nesfatin-1 in the rats. The effect of the drug was different according to the food intake of the rats. These data might suggest a potential role in CDP-choline on plasma nesfatin-1 concentration.

Diffusion des rayons X par un cristal moléculaire (cas de H. M. T.) Mise en évidence de pouvoirs diffusants d'ordres supérieurs
Authors: Damien Jean-Claude , Devos Liévin
Published: May 2019

The aim of this work is to explain some difficulties encountered in a previous work, in the interpretation of the thermal scattering power P[th] of the molecular crystal of H. M. T. If the scattering power of the second-order P₂ is considered as a correction term of P₁ and the scattering powers of the sth order P[s] (s > 2) are neglected, we find a discrepancy between the calculated and the measured quantities for large values of |X| and T = 295° K (X being along the axes [-4] and 3). The following are therefore developed :

— the method used to make an accurate calculation of P₂ with a computer ;

— a simple method giving an approximate value of P₃.

The results thus obtained show that the series (P₁+P₂+P₃) is not yet equal to the measured thermal scattering power when |X| > 0.6 Å⁻¹. We state then the condition that |X| must fulfill to ensure the convergence of the series (P₁+P₂+P₃).

Since a temperature decrease of the crystal leads to more favourable conditions, measurements were made at T # 78° K. The experimental conditions and results are stated. It is shown that P₁+P₂+P₃ is now equal to P[th] within the limit of the experimental errors.

Published: May 2019

El objetivo de este trabajo es analizar la composición mineralógica y la microestructura del gasterópodo “Borus” (Megalobulimus lorentzianus) que habita en la provincia de Córdoba y compararla con una cuenta ornamental procedente de un sitio arqueológico de cazadores-recolectores del noroeste de la misma provincia y de esta manera contar con nuevas herramientas para identificar las materias primas utilizadas en su fabricación. El análisis de difracción de rayos X en base a un ejemplar actual indicó que la concha de “Borus” está compuesta en su totalidad de aragonita, polimorfo de carbonato de calcio (CaCO3) que cristaliza en el sistema ortorrómbico. Además, el análisis de su microestructura, a través de microscopía electrónica y láser confocal, mostró una disposición prismática de los cristales. Por otro lado, este último análisis realizado en una cuenta proveniente del sitio arqueológico Alero Deodoro Roca (valle de Ongamira, provincia de Córdoba) también indicó la misma composición mineralógica y disposición prismática, lo que se interpreta como un elemento de afiliación al taxón mencionado. Con la incorporación de nuevos materiales este tipo de análisis podrá, a futuro, mejorar el conocimiento respecto a la especialización en la confección de cuentas y posibles redes de intercambio en la región central de Argentina.
Tafonomía de conjuntos arqueológicos en superficie: el caso de P 37 (desembocadura del río Santa Cruz), Patagonia meridional
Authors: Cañete Mastrángelo Daniela S. , Muñoz A. Sebastián
Published: May 2019

En este trabajo se analiza desde una perspectiva tafonómica el depósito arqueológico P 37, ubicado en la desembocadura del río Santa Cruz, Patagonia meridional. Se discuten las implicaciones que la dinámica de exposición/enterramiento de materiales arqueológicos puede tener en la interpretación de depósitos arqueológicos en superficie, para lo cual se consideran tanto los restos orgánicos como los inorgánicos, ya que ambos ofrecen distintos tipos de evidencias en lo que se refiere a la información ambiental, conductual y tafonómica. El análisis de los restos óseos y del material lítico recuperados en superficie y estratigrafía pone en evidencia que la historia tafonómica del depósito incluye momentos de mayor y menor estabilidad que están vinculados con eventos de exposición y enterramiento de los materiales. Es decir, se trata de una estructura dinámica que no se explica necesariamente por procesos direccionales de pérdida de información como sugeriría a primera vista el hecho de que se encuentran en ambientes altamente impactados por procesos erosivos. Se concluye que la utilización de líneas de evidencia independientes, pero complementarias, resulta una herramienta eficiente para discutir la naturaleza y la historia tafonómica de depósitos arqueológicos costeros afectados por ciclos alternativos de exposición y enterramiento.

Published: May 2019

Humans can see and visually sense the world around them by using their eyes and
brains. Computer vision works on enabling computers to see and process images in the same way that human vision does. Several algorithms developed in the area of computer vision to recognize images. The goal of our work will be to create a model that will be able to identify and determine the handwritten digit from its image with better accuracy. We aim to complete this by using the concepts of Convolutional Neural Network and MNIST dataset. We will also show how MatConvNet can be used to implement our model with CPU training as well as less training time. Though the goal is to create a model which can recognize the digits, we can extend it for letters and then a person’s handwriting. Through this work, we aim to learn and practically apply the concepts of Convolutional Neural Networks.

Authors: Koc Władysław
Published: May 2019

The paper presents the analytical method of modelling the diverging track of railway turnout with nonlinear curvature sections. These sections were used for smoothing the graph of curvature in the extreme areas of turnout. The problem of the curvature distribution was identified with the use of differential equations. The resulting solutions are of universal nature for example the ability of assuming any values of curvature at the beginning and ending of the layout. The comparative analysis was performed for two cases with nonlinear curvature and corresponding cases where linear curvature was used. As a result, the analysis of selected cases showed a beneficial curvature distribution in a nonlinear variant, the extreme areas of circular arc are smoothed as well as the curvature at both ends of the layout is equal to zero.

Modeling variable curvature on the turnout diverging track length
Authors: Koc Władysław
Published: May 2019

The paper presents three variants of variable curvature application on the entire length of the turnout diverging track. One linear and two nonlinear curvature cases: described by the function of C1 and C0 class were considered. It turned out that both linear curve and the function of C1 class requires a significant (even twice) length of diverging track extending with respect to the base turnout. The curvature described by the function of class C0 proved to be far more favorable, although the necessary extension of the turnout is still considerable. In the turnouts with variable curvature of diverging track it is possible to shape the horizontal ordinates flexibly by manipulating the crossing angle and radius. The study shows the effects of such a procedure, the aim of which was to obtain an appropriate value of the final ordinate.

A lot of examination on eWOM effectiveness has been done, but it is still fragmented and overlook the potential of Visual eWom (VeWOM). Departing from the electronic word-of-mouth communication framework this research attempts to provide empirical evidence on the eWOM credibility-forming aspect and its implications toward eWOM adoption rate in the context of VeWOM video "unboxing". This research was conducted by a descriptive-explanatory approach using primary data, collected through a cross-sectional online survey. The hypothesis testing is performed by analyzing structural model estimation result through Structural Equation Modeling (SEM) approach on 105 sample data of YouTube video-sharing site viewers. The proposed structural model involves three exogenous variables and three endogenous variables. The estimation results of the structural model indicate that VeWOM argument quality has a positive impact on VeWOM usefulness. Meanwhile, communicator expertise and trustworthiness proved to encourage the formation of VeWOM credibility. On the other hand, this study also proved the positive impact of VeWOM credibility on VeWOM adoption, however, the positive effect of VeWOM usefulness on VeWOM adoption was not proven in this study

New determinations are presented of the cosmic infrared background monopole brightness in the Planck HFI bands from 100 to 857 GHz. Planck was not designed to measure the monopole component of sky brightness, so cross-correlation of the 2015 HFI maps with COBE/FIRAS data is used to recalibrate the zero level of the HFI maps. For the HFI 545 and 857 GHz maps, the brightness scale is also recalibrated. Correlation of the recalibrated HFI maps with a linear combination of Galactic H i and Hα data is used to separate the Galactic foreground emission and determine the cosmic infrared background brightness in each of the HFI bands. We obtain CIB values of 0.007 ± 0.014, 0.010 ± 0.019, 0.060 ± 0.023, 0.149 ± 0.017, 0.371 ± 0.018, and 0.576 ± 0.034 MJy sr−1 at 100, 143, 217, 353, 545, and 857 GHz, respectively. The estimated uncertainties for the 353–857 GHz bands are about 3–6 times smaller than those of previous direct CIB determinations at these frequencies. Our results are compared with integrated source brightness results from selected recent submillimeter and millimeter wavelength imaging surveys.

The binary emission-line system, particularly the binary broad-line emission system, is considered the most effective indicator of the black hole binary. A plausible example of such a system, SDSS J153636.22+044127.0, was reported as the first known object with two hydrogen Balmer broad-line systems, which are interpreted to be the result of broad-line regions around a pair of black holes. Here, we show the follow-up optical and near-infrared spectral observations of SDSS J153636.22+044127.0 and its analogs. In these objects, the broad hydrogen Balmer and Paschen, He i, and Mg ii lines share the same peculiar emission-line profile (including a blue system, a red system, and a double-peaked disk-line component); however, the invariance in the large time interval, the absence of the blue system in He i
λ10830 profile, and the abnormally strong emission of the hydrogen Paβ blue system oppose the binary proposal. We suggest that these unique broad lines arise from the active galactic nucleus emission-line region and the shock-heated outflowing gases rather than a binary system of two active black holes.

Published: May 2019

BACKGROUND: Hospital Information System (HIS) is a type of health information system which is widely used in clinical settings. Determining the success rate of HISs is an ongoing area of research since its implications are of interest for researchers, physicians and managers.
AIM: In the present study, we develop a novel instrument to measure HIS success rate based on users’ viewpoints in a teaching hospital.
METHODS: The study was conducted in Ebnesina and Dr Hejazi Psychiatric Hospital and education centre in Mashhad, Iran. The instrument for data collection was a self-administered structured questionnaire based on ISSM, covering seven dimensions, which includes system quality, information quality, service quality, system use, usefulness, satisfaction, and net benefits. The verification of content validity was carried out by an expert panel. The internal consistency of dimensions was measured by Cronbach’s alpha. Pearson’s correlation coefficient was calculated to evaluate the significance of associations between dimensions. The HIS success rate on users’ viewpoints was determined.
RESULTS: A total of 125 users participated in the study. The instrument was validated by an expert panel with the Content Validity Index (CVI): 0.85 and Content Validity Ratio (CVR): 0.86. The overall Cronbach’s alpha value of the instrument was 0.93. The Pearson correlation coefficient showed significant positive relationships among the investigated dimensions. On average, HIS success rate in the hospital under study was 65% (CI: 64%, 67%). The dimensions of “usefulness”, “system quality”, and “net benefits” showed the highest rates of success, respectively.
CONCLUSION: The instrument used in this study can be adopted for HIS evaluation in future studies. In the current study, a method was developed to determine the HIS success rate based on users’ viewpoints. This method allows for the comparison of HIS success rates in various hospitals. As well, our findings underscore the viewpoints of HIS users in a developing country.
Impact of Early Postnatal Weight Gain on Retinopathy of Prematurity in Very Preterm Infants in Southwestern Ontario
Authors: Li Yingxiang , Shah Meera , Miller Michael R. , Lee David S. C. , Sharan Sapna
Published: May 2019

Purpose:

To examine the relationship between post-natal growth and development of retinopathy of prematurity (ROP) among preterm infants in southwestern Ontario.

Methods:

The medical records of 431 preterm infants, born between January 1, 2008, and June 1, 2015, with a gestational age (GA) of less than 31 weeks or birth weight (BW) of less than 1,250 g were reviewed. Information collected included pregnancy and birth history, neonatal characteristics, ROP status, comorbidities, and postnatal weight measurements at specified intervals. Infants diagnosed as having ROP and no ROP were compared.

Results:

Low weight velocity from day 7 to day 28 (
P
< .001), high weight velocity from birth to first day of full enteral feeding (FEF) (
P
< .001), long duration from birth to FEF (
P
< .001), and long duration from FEF to discharge/transfer (
P
< .001) were associated with ROP. After controlling for GA and BW, the durations, birth to FEF, and FEF to discharge/transfer remained significant (
P
< .05). In a multivariable logistic regression analysis adjusting for GA, bronchopulmonary dysplasia, and surgical ligation for patent ductus arteriosus, the only independent risk factor of ROP was duration from FEF to discharge/transfer (
P
< .05).

Conclusions:

Low weight velocity from day 7 to day 28 may be a useful predictor for the development of ROP but is dependent on GA and BW. A delay to reach FEF, which is associated with comorbidities of ROP, appears to be a risk factor for ROP that is independent of GA and BW.

A Cluster of Cyclic Esotropia: White Matter Changes on MRI and Surgical Outcomes
Authors: Merrill Kimberly , Anderson Jill , Watson Daniel , Areaux Raymond G.
Published: May 2019

Purpose:

To report a series of patients with cyclic esotropia, their surgical outcomes, and incidental findings.

Methods:

The medical records of five patients with cyclic esotropia presenting over 17 months were reviewed. Age at onset, ocular and motility examinations, brain magnetic resonance imaging (MRI), acetylcholine receptor antibodies, thyroid hormone levels and antibodies, calendars documenting phases, surgical treatments, postoperative alignment, and fusion were documented.

Results:

Three boys and two girls presented at 3 to 4 years old in 2015–2016. Typical periodicity followed a 48-hour cycle. Duration of cycling varied from 1 to 9 weeks. Mean maximum deviation was 37 prism diopters (PD) of esotropia (range: 35 to 40 PD of esotropia). All patients had normal laboratory studies. MRIs showed an abnormal white matter signal in the frontal lobes in 2 patients and were normal in the others. Bilateral medial rectus recessions for the maximum angle were successful in 4 patients at a minimum follow-up of 13 months; the other patient required reoperation for a residual esotropia. Fusion was present in 4 patients preoperatively and all postoperatively. Stereopsis was stable or improved in all postoperatively.

Conclusions:

This is the first report of frontal white matter changes occurring in the setting of cyclic esotropia. MRI with attention to frontal lobe white matter might be considered in the work-up of cyclic esotropia to determine if this is a common finding. Bilateral medial rectus recessions can restore fusion in these patients.

Security Challenges and Resolution in Cloud Computing and Cloud of Things
Authors: Rath Mamata
Published: May 2019

Cloud computing is a developing zone of computing innovation that shapes the handling power and the computing assets of many associated, topographically separated PCs associated by means of internet. Cloud computing wipes out the need of having a total framework of equipment and programming to meet clients' prerequisites and applications. It very well may be thought of as a total or an incomplete outsourcing of equipment and programming assets. To get to cloud applications, a great internet association and a standard internet program are required. Cloud computing has its own particular downside from the security perspective; this chapter addresses the vast majority of these dangers and their conceivable arrangements. Cloud computing gives its client numerous abilities like getting to an expansive number of utilizations without the requirement for having a permit, acquiring, introducing, or downloading any of these applications.
Failure Detectors of Strong S and Perfect P Classes for Time Synchronous Hierarchical Distributed Systems
Authors: Verma Anshul , Singh Mahatim , Pattanaik Kiran Kumar
Published: May 2019

Present failure detection algorithms for distributed systems are designed to work in asynchronous or partially synchronous environments on mesh (all-to-all) connected systems and maintain status of every other process. Several real-time systems are hierarchically connected and require working in strict synchronous environments. Use of existing failure detectors for such systems would generate excess computation and communication overhead. The chapter describes two suspicion-based failure detectors of Strong S and Perfect P classes for hierarchical distributed systems working in time synchronous environments. The algorithm of Strong S class is capable of detecting permanent crash failures, omission failures, link failures, and timing failures. Strong completeness and weak accuracy properties of the algorithm are evaluated. The failure detector of Perfect P class is capable of detecting crash failures, crash-recovery failures, omission failures, link failures, and timing failures. Strong completeness and strong accuracy properties of the failure detector are evaluated.

Published: May 2019

Under industrial conditions, it is common to avoid undesirable costly modernization of the existing equipment and increase the production efficiency. That is why as a basis of the solution to the scientific-applied problem, the authors took the idea of the adjustment of temperature-deformation regimes of metal-roll thick plate rolling for building constructions of the certain assignment in the way to initiate heterogeneous origination of ferrite on the polygonal boundaries of austenite as well as to form, before the finish rolling, as much as possible dispersed grain of hypoeutectoid ferrite. It must guarantee the formation of highly-dispersed final ferrite-perlite structure and the high level of strength and plasticity of the thick plate.
