Cyclical Fluctuations in the Banking Services Market and the Changes in the Situation of Entities from the Financial Services Sector
Authors: Skikiewicz Robert , Garczarczyk Józef 
Published: July 2019

Abstract
Section K of the services sector includes entities conducting financial and insurance activities and, among others, banks. Fluctuations in the whole economy and its individual sectors’ situation are interrelated; hence, one may also expect similarities of cyclical fluctuations in the banking sector and in the entire financial sector. The analyses in the article concern the connections between the cyclical fluctuations on the banking services market and in the entire K section of the services sector, grouping entities conducting financial and insurance activities in Poland. The analyses proved that changes in the economic situation appear earlier in the banking sector than in section K of the services sector. The time range of analyses covered the period from the first quarter of 2003 to the first quarter of 2018. Conclusions on relationships were formulated on the basis of cross-correlation analysis and the analysis of the turning points in the time series of variables describing the cyclical fluctuations in the banking market and in the K section of the services sector.
Comparison of the method of variation of parameters to semi-analytical methods for solving nonlinear boundary value problems in engineering
Authors: Moore Travis J. , Ertürk Vedat S. 
Published: July 2019

AbstractSolutions to nonlinear boundary value problems modelling physical phenomena in engineering applications have traditionally been approximated using numerical methods. More recently, several semi-analytical methods have been developed and used extensively in diverse engineering applications. This work compares the method of variation of parameters to semi-analytical methods for solving nonlinear boundary value problems arising in engineering. The accuracy and efficiency of the method of variation of parameters are compared to those of two widely used semi-analytical methods, the Adomian decomposition method and the differential transformation method, for three practical engineering boundary value problems: (1) the deflection of a cantilevered beam with a concentrated load, (2) an adiabatic tubular chemical reactor which processes an irreversible exothermal reaction, and (3) the electrohydrodynamic flow of a fluid in an ion drag configuration in a circular cylinder conduit. The accuracy and convergence of each method is investigated using the error remainder function. The method of variation of parameters is significantly more efficient than both the semi-analytical methods and traditional numerical methods while maintaining comparable accuracy. Unlike the semi-analytical methods, the efficiency of variation of parameters is independent of the nonlinearity. Variation of parameters is shown to be an attractive alternative to semi-analytical methods and traditional numerical methods for solving boundary value problems encountered in engineering applications in which solution efficiency is important.

Published: July 2019

Abstract
Expansive clayey soils cover wide areas in Syria. Their undesirable properties have caused serious damage to infrastructure. Many attempts have been made to stabilize the expansive clayey soils, most common of which was the use of lime. No detailed work on using calcined expansive clay as a soil stabilizing agent was found in the literature. The objective of this article is to investigate the effect of nanocalcined clay and nanolime on some geotechnical properties of the expansive clayey soil. Three expansive clayey soil specimens quarried from three different sites in the south of Syria have been investigated. They were thermally treated at three different levels (450°C, 650°C, and 850°C) for 3 h. Then, they were ground to have a particle size of less than 100 nm. Three replacement levels of nanocalcined clay were used, i.e., 0, 1, and 2 %. The X-ray diffractometer technique was employed to detect the crystalline and glassy phases in the clayey samples before and after the thermal treatment. Pozzolanic activity of the thermally treated clayey soil was studied using the modified Chapelle test at each of the temperature levels. Atterberg limits, compaction, free swell, swelling pressure, linear shrinkage, and shear strength have particularly been investigated. Test results revealed the positive effect of nanocalcined clay when added to the original soil. Plasticity index was reduced by more than 50 % when 2 % nanocalcined clay was added to the original soil. In addition, 0.6 % nanolime has been added to further investigate the combined effect of nanolime and nanocalcined clay on the properties of the clayey soil. All investigated properties have significantly been improved when nanocalcined clay and nanolime were added together, i.e., swelling pressure and linear shrinkage values were reduced to less than 15 % when compared with those of the original soil.

Published: July 2019

Abstract
The present study attempts to investigate the thermal performance of five types of mild steel air channels in the photovoltaic thermal hybrid system. This system has been designed, fabricated, and tested in the tropical climatic condition of Chennai, India. There are five kinds of air channels studied in this work, namely, reference air channel, single-fin channel, multifin channel, fin with T baffle channel, and fin with V baffle channel. These channels are studied and compared. The experiments were accomplished with two mass flow rates, m˙: 0.00565 and 0.00847 kg/s. The photovoltaic thermal hybrid system performance was enhanced by increased air velocity, enhanced heat transfer between the absorber surface and air, and physical geometry of the channel. This optimal performance has been attained in the present study, with strong agreement with previously published findings. The photovoltaic thermal hybrid system experimentally proved to enhance thermal and photovoltaic efficiencies with increasing air mass flow rate, and the maximum electrical efficiency was found to be 13.70 % at the mass flow rate of 0.00565 kg/s and 14.27 % at the mass flow rate of 0.00847 kg/s; similarly, the thermal efficiency was 14.12 % at m˙ = 0.00565 kg/s and 20.81 % at m˙ = 0.00847 kg/s.

Abstract
Slurry seals are a hard wearing surface for pavement preservation. The main purpose of this study is to investigate the effects of nanomaterials and styrene butadiene rubber (SBR) latex on fatigue and rutting performance, wet cohesion properties, abrasive performance, and raveling resistance of the fiber-reinforced slurry seal. Firstly, the optimal slurry seal composition was determined under the effect of SBR polymer and synergistic nanomaterials. Results showed that simultaneous addition of nanolime and nanoclay significantly improves the fatigue life and rutting resistance of slurry seal mixtures. In addition, the simultaneous addition of nanomaterials reduces the amount of abrasion by about 63 % and significantly enhances the resistance of a slurry seal mixture. Moreover, the combination of nanomaterials, in particular, nanoclay, with 4 % modified asphalt binder, increases the raveling resistance and ultimately improves the friction resistance of the slurry seal. Finally, after comparing the performance of different mixtures, the slurry seal modified with polyester fiber with 8 % asphalt binder emulsion containing 6 % latex, 3 % nanoclay, and 3 % nanolime was determined as the optimum mixture. The analysis of variance showed that the nanomaterials have a significant effect on the fatigue and rutting properties, adhesion and cohesion resistance and abrasion performance of slurry seal at the confidence level of 95 %.

Authors: Marashdeh Mohammad W. 
Published: July 2019

Abstract
The linear and mass attenuation coefficients of raw Rhizophora spp. wood, binderless particleboard, and Perspex were measured at gamma ray energies of 59.54, 88.0, and 356 keV. Americium-241, cadmium-109, and barium-133 point sources were used to produce gamma rays in this work. Results were compared with the theoretical values of water calculated using the XCOM program. The mass attenuation coefficients of binderless particleboard and water showed good agreement, with discrepancies of approximately 0.1, 0.6, and 0.1% at 59.54, 88.0, and 356 keV, respectively. The measurements of raw Rhizophora spp. wood and water had discrepancies of 0.7, 0.9, and 0.8% at 59.54, 88.0, and 356 keV, respectively, and those of Perspex and water had discrepancies of 0.3, 0.9, and 0.2% at the same photon energies. Moreover, Rhizophora spp. binderless particleboard was compared with water in terms of effective atomic number (Zeff), and a close match was noticed. In addition, the half-value layers of the experimental samples were measured at 59.54, 88.0, and 356 keV. The calculated values of water and the experimental results of binderless particleboard were in good agreement, indicating that binderless particleboard can be used as a phantom material in the range of photon energy 59.54–356 keV.

Abstract
Femoral stem fractures in total hip arthroplasty (THA) are a problem in clinical practice that results in great morbidity and high cost of revision hip surgery. Stem fractures are multifactorial events that are usually related to a combination of factors that increase the mechanical stress on the stem or decrease the mechanical strength of the implant. Failure analyses of hip prosthesis have identified that the presence of inadequate grain size may lead to implant failure. The aim of this article is to develop a rational to set specific sites to perform grain size measurements along stems used in THA as well as appropriate procedures to evaluate the heterogeneity of the microstructure related to the grain size distribution. In the present study, nonmodular femoral stems from three manufacturers with different wrought materials were chosen: stainless steel ISO 5832-1 (Manufacturer I), high nitrogen stainless steel ISO 5832-9 (Manufacturer II), and cobalt-chromium-molybdenum alloy ISO 5832-12 (Manufacturer III). The results of this study showed a great variability of grain size number depending on the cross section and fields evaluated. Therefore, the current technical standards for evaluating THA stems need to be modified. Analyses of grain sizes at different cross sections and inside each cross section of the stem is necessary to ensure the safety of hip stems.

Abstract
Infectious pancreatic necrosis (IPN) is a viral disease with considerable negative impact on the rainbow trout (Oncorhynchus mykiss) aquaculture industry. The aim of the present work was to detect genomic regions that explain resistance to infectious pancreatic necrosis virus (IPNV) in rainbow trout. A total of 2,278 fish from 58 full-sib families were challenged with IPNV and 768 individuals were genotyped (488 resistant and 280 susceptible), using a 57K SNP panel Axiom, Affymetrix. A genome-wide association study (GWAS) was performed using the phenotypes time to death (TD) and binary survival (BS), along with the genotypes of the challenged fish using a Bayesian model (Bayes C). Heritabilities for resistance to IPNV estimated using genomic information, were 0.53 and 0.82 for TD and BS, respectively. The Bayesian GWAS detected a SNP located on chromosome 5 explaining 19% of the genetic variance for TD. The proximity of Sentrin-specific protease 5 (SENP5) to this SNP makes it a candidate gene for resistance against IPNV. In case of BS, a SNP located on chromosome 23 was detected explaining 9% of the genetic variance. However, the moderate-low proportion of variance explained by the detected marker leads to the conclusion that the incorporation of all genomic information, through genomic selection, would be the most appropriate approach to accelerate genetic progress for the improvement of resistance against IPNV in rainbow trout.

Abstract
Binge eating (BE) is a heritable trait associated with eating disorders and involves episodes of rapid, large amounts of food consumption. We previously identified cytoplasmic FMR1-interacting protein 2 (Cyfip2) as a genetic factor underlying compulsive-like BE in mice. CYFIP2 is a homolog of CYFIP1 which is one of four paternally-deleted genes in patients with Type I Prader-Willi Syndrome (PWS), a neurodevelopmental disorder whereby 70% of cases involve paternal 15q11-q13 deletion. PWS symptoms include hyperphagia, obesity (if untreated), cognitive deficits, and obsessive-compulsive behaviors. We tested whether Cyfip1 haploinsufficiency (+/−) would enhance compulsive-like behavior and palatable food (PF) intake in a parental origin- and sex-dependent manner on two Cyfip2 genetic backgrounds, including the BE-prone C57BL/6N (Cyfip2N/N) background and the BE-resistant C57BL/6J (Cyfip2J/J) background. Cyfip1+/− mice showed increased compulsive-like behavior on both backgrounds and increased PF intake on the Cyfip2N/N background. In contrast, maternal Cyfip1 haploinsufficiency on the BE-resistant Cyfip2J/J background induced a robust escalation in PF intake in wild-type Cyfip1J/J males while having no effect in Cyfip1J/- males. Notably, induction of behavioral phenotypes in wild-type males following maternal Fmr1+/− has previously been reported. In the hypothalamus, there was a paternally-enhanced reduction in CYFIP1 protein whereas in the nucleus accumbens, there was a maternally-enhanced reduction in CYFIP1 protein. Nochange in FMR1 protein (FMRP) was observed in Cyfip1+/− mice, regardless of parental origin. To summarize, Cyfip1 haploinsufficiency increased compulsive-like behavior and induced genetic background-dependent, sex-dependent, and parent-of-origin-dependent effects on PF consumption and CYFIP1 expression that could have relevance for neurodevelopmental and neuropsychiatric disorders.

Abstract: Tacrolimus is an important part of immunosuppressive therapy after solid organ transplantation. The therapeutic range of the drug from the calcineurin inhibitor group is narrow. Adjustment of the blood concentration can be very complicated but to be able to avoid the occurrence of side effects or ineffective immunosuppression it is inevitable. This article summarizes the properties of tacrolimus pharmacokinetics, pharmacogenetics and pharmacodynamics. We will focus on individual variations of cytochrome enzymes. In the following part, a new method for screening high risk patients will be introduced. We will present the publications of the determination of the concentration/dose (C/D) ratio. By determining the C/D ratio, researchers identify fast and slow metabolizing patient groups. Fast metabolizers require higher doses in general and the occurrence of complications is also more frequent in this group. Long-term results are lagging behind the slow metabolizing group. The long-term results of renal transplantation nowadays contribute to the postoperative period and the later years rather than the surgery itself. It includes the proper management of previous illnesses (e.g., hypertension, diabetes, endocrinological problems), detection of complications (e.g., infections, malignancies), and the precise regulation of immunosuppressive therapy.
