A thermodynamic investigation of the LiBH4–NaBH4 system

The LiBH4–NaBH4 pseudo-binary system has been investigated by X-ray diffraction, temperature-programmed photographic analysis, and differential scanning calorimetry, in order to establish the phase diagram. The polymorphic orthorhombic-to-hexagonal phase transition of LiBH4 was observed at 94 °C in samples containing NaBH4, i.e. 15 °C lower than for pure LiBH4, which indicates the dissolution of sodium into LiBH4. The formation of solid solutions was confirmed by powder X-ray diffraction measurements performed as a function of temperature. A new eutectic composition between Li0.65Na0. 35BH4 and Li0.70Na0. 30BH4, with a melting temperature of 216 °C, is observed. Ab initio calculations have been performed to establish the relative stabilities of the pure compounds in orthorhombic, hexagonal and cubic structures. The obtained experimental and calculated data were compared with available literature values and they were used for a thermodynamic assessment of the LiBH4–NaBH4 system by the calphad method. The enthalpy of mixing for solid and liquid solutions has been estimated on the basis of experimental data.
Wpływ procesu KOBO na właściwości stopu CuCr1Zr Influence of KOBO process on the properties of CuCr1Zr alloy

The authors of this article conducted tests on CuCr1Zr alloy for the purpose of improving its mechanical properties and determining their stability at elevated temperatures. An unconventional plastic working method was utilized – KOBO extrusion. The idea of the KOBO method is based on external forcing of localized plastic flow in shear bands through the superposition onto the unidirectional operational force action of forming tools of an additional, cyclically variable action in a direction different from the direction of the given process’s operating direction. A rod in T6 state was extruded (unsuccessfully), followed by a extrusion of rod after hyperquenching from temperatures of 900 and 1030°C (test successful). KOBO extrusion was performed for hyperquenched rods with two cooling variants (in air and in water). During the KOBO extrusion process, the cross-section of rods was reduced from φ40 mm to approx. φ 12 mm, which yielded a reduction ratio of approx. 11.1 for an actual deformation of approx. 2.4. Rods, in original state and after KOBO extrusion, were subjected to hardness tests, static compression testing at room temperature and elevated temperature up to 450°C. Based on the obtained test results, it can be stated that the application of the method of plastic deformation (KOBO extrusion) makes it possible to harden the extent that the values of its strength properties exceed the values obtained after heat treatment (T6 state). However, at 450°C, strength properties decrease by 25 to 40%.
DETECTION OF SUBSURFACE CAVITIES BY THE ELECTROMAGNETIC METHOD (Case Study at Haditha Area)

Two EM techniques, terrain conductivity and VLF-Radiohm resistivity (using two different instruments of Geonics EM 34-3 and EMI6R respectively) have been applied to evaluate their ability in delineation and measuring the depth of shallow subsurface cavities near Haditha city. Thirty one survey traverses were achieved to distinguish the subsurface cavities in the investigated area. Both EM techniques are found to be successfiul tools in study area. INTRODUCTION The development in Iraq has necessitated a new vast areas for housing, construction and agriculture. Most of the new land is characterized by high gypsum content and various geotechnical problems. So the obtaining of the required subsurface geotechnical informations prior to the erection of any large engineering construction are very important from both economic and safety point of view. For this reason. geophysical methods play an increasingly important role in the providing of this informations (such as assessment of the top layers; location, trend and depth of the shallow subsurface anomalies features). Of the many different surface geophysical methods; the one which has been used in the present study is the electromagnetic method. It falls in two categories: the fixedsource technique and moving source-receiver technique. These techniques have several advantages over other geophysical surveys. The most important of these do not require the use of potential field and current electrodes as in the gravity survey and resistivity sounding. Therefore; field measurements are very rapid and data acquisition includes low cost, easy operation, speed and accuracy. Also the instruments give readings directly in mappable units. The most of successful applications of these two EM techniques were published in different parts of the world including different studies such as: Stewart (1982), Ritsema (1983), Baker and Zaynal (1985,1986 & 1987), Baker and Abdul Razzak (1985,1986 a&b), Stewart and Bretnall (1986), Zaynal and Tobia (1989), Al-Naib et al (1989), Al-Omari et al (1989). This work has investigated location and depth of the subsurface cavities (filled with water) in Haditha area within the skin depth through using the electromagnetic method. The electrornainetic method and the measuring instruments Electromagnetic induction methods utilize current flow induced in the subsurface material by a surface transmitter. An alternating electric current produced in a transmitter coil generates an alternating magnetic field, which in turn induces current flow through the earth material. The secondary magnetic field generated by the induced current is sensed by a receiver coil. The secondary field sensed at the coil depends on the strength of the primary
Morphometric analysis and prioritization of sub‑watersheds for soil erosion using Geomatics technologies in Megech River catchment, Lake Tana Basin, North Western Ethiopia

Soil erosion is one of the most critical environmental problems in the sustainable development of agriculture and natural resources. Ethiopia is facing severe soil erosion problems. The present study was carried out in the Megech River catchment, Lake Tana Basin, North Western Ethiopia. The present study aims to identify the sensitive soil erosion-prone sub-watersheds in the Megech River catchment. ASTER-DEM (Advanced Space-borne Thermal Emission and Reflection), a 30 m spatial resolution digital elevation model (DEM), was used to delineate the sub-watersheds and drainage networks through spatial Analyst and ArcHydro extension of ESRI ArcGIS v10.6. 1 software. The cloud-free optical satellite data got from Landsat-8 Operational Land Imager (OLI) has been used to update the drainage network of the present study area. The study area was divided into four sub-watersheds: WS-1, WS-2, WS-3, and WS-4. The primary, linear, and areal drainage morphometric parameters were calculated by applying the standard formula. Furthermore, the ranks were allocated to each drainage morphometric parameter of the four sub-watersheds based on their soil erosion proneness. The compound factor value was calculated for the sub-watersheds. The lower value of the compound factor has a high possibility of soil erosion and vice versa. The compound factor of the present study area's sub-watersheds is 2.33 (WS-1), 2.88 (WS-2), 2.11(WS-3), and 2.67 (WS-4). Based on the compound factor value, the present study area's sub-watersheds 3,1,4 and 4 were classified into very high, high, medium, and low priority sub-watersheds, respectively. Through morphometric drainage analysis, the sub-watershed-3 has been identified as a very high-priority ranked watershed in the present study. It needs immediate soil conservation measures for efficient watershed planning and management. Further, the present study shows the effectiveness of the drainage morphometric analysis using the satellite image and GIS techniques in prioritizing the sub-watersheds for soil resource conservation and management in the Megech River catchment, Lake Tana Basin, North Western Ethiopia.
Liquid Biopsy in Prostate Cancer Diagnosis and Prognosis: A Narrative Review

Prostate cancer involves a considerable percentage of men worldwide and as be postulated; prostate cancer epidemiology is not restricted to a specific country. Despite tremendous efforts that have been made regarding prostate cancer diagnosis and treatment, this issue remains challenging for urologists and oncologists by far. The routine method for the diagnosis of prostate cancer is a prostate biopsy, which may accompany by several complications that may be detrimental to patients’ health. Consequently, an alternative method with lower rates of complications is necessitating. For almost two decades liquid biopsy, an alternative method for cancer diagnosis with obvious benefits in comparison with previous methods of cancer diagnosis, has been at the center of interest of many studies, in particular, studies with prostate cancer subjects. The applicability of liquid biopsy which primarily includes cell-free DNA, circulating tumor cells, RNAs, and exosomes in prostate cancer is the main area of research of recent research. However, using liquid biopsy in routine clinical practices yet has not occurred and further studies with more firm evidence are warranted. Herein, we provided a brief report of advancements that have occurred in prostate cancer.

FEB-Stacking and FEB-DNN Models for Stock Trend Prediction: A Performance Analysis for Pre and Post Covid-19 Periods

In this paper, stock price prediction is perceived as a binary classification problem where the goal is to predict whether an increase or decrease in closing prices is going to be observed the next day. The framework will be of use for both investors and traders. In the aftermath of the Covid-19 pandemic, global financial markets have seen growing uncertainty and volatility and as a consequence, precise prediction of stock price trend has emerged to be extremely challenging. In this background, we propose two integrated frameworks wherein rigorous feature engineering, methodology to sort out class imbalance, and predictive modeling are clubbed together to perform stock trend prediction during normal and new normal times. A number of technical and macroeconomic indicators are chosen as explanatory variables, which are further refined through dedicated feature engineering process by applying Kernel Principal Component (KPCA) analysis. Bootstrapping procedure has been used to deal with class imbalance. Finally, two separate Artificial Intelligence models namely, Stacking and Deep Neural Network models are deployed separately on feature engineered and bootstrapped samples for estimating trends in prices of underlying stocks during pre and post Covid-19 periods. Rigorous performance analysis and comparative evaluation with other well-known models justify the effectiveness and superiority of proposed frameworks.
β-elemene Induces Caspase-Dependent Apoptosis in Human Glioma Cells in Vitro-Changes in Bax, Fas/FasL and Bcl-2

Gliomas are the most common and malignant type of primary brain tumor in adult central nervous system, representing over 50% of all primary intracranial tumors. Despite recent advances in the development of surgery and adjuvant therapy, it remains difficult to completely remove gliomas by conventional approaches. And the prognosis for patients with glioma is only 10-14 months on average (Louis et al., 2007; Buonerba et al., 2011). Elemene, extracted from a traditional Chinese herb medicine Curcuma wenyujin, is a mixture of β-, γ-, and
Comprehensive In silico Analysis of Single Nucleotide Polymorphisms (SNPs) in Human BDNF Gene

Since a number of single nucleotide polymorphisms (SNPs) are associated with the BDNF gene mutations involved in different diseases. Hence, it is important to find out the probable functional SNPs before planning a larger population study. So, to look out for the functional nsSNPs (non-synonymous single nucleotide polymorphisms) in BDNF gene, existing data present in the dbSNP database and different bioinformatics tools like SIFT, PolyPhen, nsSNPAnalyzer, F-SNP, I-mutant, Pymol were used for the analysis. The results showed that out of the total 2929 SNPs, 58 were nsSNPs (non-synonymous single nucleotide polymorphisms), 44 occurred in the mRNA 3′ UTR, 108 occurred in 5′ UTR region, 257 occurred in intronic regions and the rest were other types of SNPs. SIFT and PolyPhen programs predicted 3 out of 58 nsSNPs (rs8192466, rs1048218, and rs77787410) as not tolerable, deleterious and damaging. F-SNP revealed that the rs1048221, rs1048220, rs1048218, rs6265 and rs8192466 SNP in the non-synonymous coding region may have protein-coding and splicing regulator functions. PDBSum and UniProtKB predicted the number of protein structures, sharing 100% similarity with the BDNF amino acid sequence. Moreover, I-Mutant and nsSNPAnalyzer showed a decrease in stability for these nsSNPs upon mutation. Protein structural analysis with these amino acid variants was performed by using I-Mutant and PyMOL. This study suggested that three nsSNPs, rs8192466, rs1048218, and rs77787410 were identified as deleterious, thus destabilizing the protein stability, amino acid interactions, and hydrogen bond networks of the protein directly or indirectly. Hence, these SNPs can explain the functional deviation of protein to some extent.
Analytical Model for Data Consistency on Private Cloud Storage System

Cloud computing paradigm contains many shared resources such as infrastructures, data storage, various platforms and software. In cloud storage service, consistency not only influences the performance and availability of the systems but also the overall operational cost. This paper is proposed an analytical model using MM1 queuing for data consistency on private cloud storage system to evaluate the discarding probability based on update requests to handle update conflict. After updating data, replicas can be active or inactive in the system. In this paper, Markov Chain is applied for a replica to improve the readability and consistency of storage on the cloud environment.

The Effect of Eight-week Caffeine Supplementation and High-Intensity Interval Training on the Serum Urea and Creatinine Levels and Morphological Changes of Glomerular Unit in Diabetic Rats

Background: Glomerulonephritis is the one of disorders associated with diabetes. The present study was conducted to investigate the effect of 8-week high-intensity interval training (HIIT) and caffeine supplementation on the levels of serum creatinine (Cr) and blood urea nitrogen (BUN) and morphological changes of kidney tissue in diabetic rats. Methods: 50 diabetic rats as streptozotocin (STZ)-induced diabetic rats were randomly assigned to 5 equal groups including control, diabetic, diabetic + caffeine, diabetic + training, and diabetic + training + caffeine. The groups were given supplements (intraperitoneal injection of 70 mg/kg of caffeine powder for five days in each week) and underwent training (5 sessions including 6 to 12 times of 2-minutes training at the rate of 85-90% of maximal speed each week ) for 8 weeks. The serum Cr and BUN levels and the morphological changes of kidney tissue after 48 hours of the last training session were measured. Statistical analysis was performed by one- and two-way ANOVA (P<0.001). Results: It was revealed that HIIT reduced the levels of Cr (P=0.001) and BUN (P=0.013), as well as the urinary tract area (P=0.015) in diabetic rats. Although caffeine supplementation significantly reduced glomerular area (P=0.001) but increased BUN level (P=0.001) and Bowman's capsule (P=0.001) in them. There was a significant interaction between treatments regarding BUN level and urinary tract area changes (P=0.001, P=0.014, respectively). Conclusion:HIIT and caffeine supplementation had significant effects on the serum Cr and BUN levels and morphological changes in rats' kidney tissues, but given doses and time of consumption of caffeine, as well as duration and intensity of training were more effective than the other indicators.
Multilocus Sequence Typing of Pasturella multocida Isolates from Different Animal Species

The present study was carried out to characterize six Pasteurella multocida isolates obtained from sheep, duck, pig, cow, poultry, and P. multocida P52 vaccine strain by multilocus sequence typing (MLST). All the isolates were first confirmed positive for P. multocida by culturally first and then by a biochemical method. The Deoxyribonucleic acid (DNAs) were extracted from the isolates and PM-PCR was carried out, which confirmed all the isolates as P. multocida, and further studied for capsular typing. Among them three isolates of P. multocida were typed as capsular type A (sheep, duck and poultry), and the other two were typed as capsular type B (cow and pig). Specific primers and protocols described in the Rural Industries Research and Development Corporation (RIRDC) MLST scheme for P. multocida were used to amplify the seven house-keeping genes, viz., adk, est, pmi, zwf, mdh, gdh, and pgi. The purified PCR products were subjected to sequencing by Sanger's method. The total length sequences of genes were trimmed to the length of 466 bp, 535 bp, 602 bp, 500 bp, 521 bp, 530 bp, and 560 bp for adk, est, pmi, zwf, mdh, gdh and pgi genes, respectively, as described in the RIRDC MLST scheme. Isolates of sheep, duck, pig, cattle, poultry, PAS-506/06, PAD-914/11, PAP-721/09, PAC-93/15, PAP-87/13 and P52 vaccine strain were grouped to sequence type 122, 307, 308, 309, 129 and 122, respectively.
Boosting of Tolerance for Disagreement and Need to Belong Via Satisfaction, Psychological Well Being and Resilience among University Undergraduate Students

The present study examines the presence of satisfaction with life, psychological well-being and resilience will boost up tolerance for disagreement and need to belong among undergraduate students of university. To test the model, three factors (satisfaction with life, psychological well-being and resilience) are used to predict student’s tolerance for disagreement and need to belong which are important variables in academic achievement and constructive life. We administered scales of tolerance for disagreement, need to belong, satisfaction with life, Ryff’s psychological well-being and resilience. Using correlation and regression (path analysis) analysis, findings of the study explored that life satisfaction, PWB and resilience are predicting disagreement tolerance and belongingness need. This study is limited to one public university. Applied significance of the study is, it will help policy makers, educational planners, parents, counselors etc. to devise strategies which increase the satisfaction, psychological well-being and resilience will ultimately increase the disagreement tolerance and sense of belonging among students.
Isoform profile of NOS enzyme in structure of rats’ solitary-vagal complex in arterial hypertension of various origin

Materials and methods. The study was performed on 30 aged male rats. Among them, 20 Wistar rats were divided into two groups – control (10 rats) and 10 rats with simulated endocrine-salt AH (ESAH) and 10 SHR rats. An immunohistochemical method was used to study the of nitric oxide synthase isoforms expression features in DMN and NTS. The following parameters were determined: the content of immunoreactive material (IRM) for the studied peptides (Uif), the relative area of the IRM (%) and the IRM concentration in 1 μm2 (Uif/μm). Results. It was found that in rats with both models of AH, the expression indices of all three nitric oxide synthase (NOS) isoforms in the studied structures increased. In our opinion, this is due to the activation of the studied structures in AH conditions. This must be considered as an important element of high blood pressure compensating. It is achieved through the implementation by a complex of mechanisms like reducing of the sympathetic tone and increasing of the parasympathetic tone by activating a system of secondary messengers; improving neurotrophy due to the high activity of constitutive NOS isoforms; iNOS-mediated NO overproduction, as a factor in compensating for its bioavailability in conditions of local ischemia in AH.
Some of Ecological, Behavioral Aspects and Control of Mediterranean Fruit Flies, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in Grape Orchards

Experiments conducted in table grape orchard, variety crimson (late-ripening, red seedless table grape variety) at Nubaria-district, Beheira-Governorate-Egypt, during blooming and fruiting periods (May to October) of seasons, 2019-2020. Results showed that, medfly males were most active during morning 7:0010:00am (0.98. and 0.905 males/trap/hour in 1 and 2 seasons, respectively) than other day. Lowest trapped males number (0.012 and 0.028 males/trap/hour in 1 and 2 seasons, respectively) recorded during period from 19.00pm-7.00am of next-day (night-hours). Results cleared that, high traps captured more male fly's number than low and appropriate trap height for medfly males in grape orchard at 2.5m above ground (0.451 and 0.524 males/trap/hour in 1 and 2 season, respectively). Minimum trap catch recorded in traps which kept at height 0.5m above ground (0.216 and 0.201 males/trap/hour in 1 and 2 season, respectively). Infestation grape bunches and berries by medfly studied in relation to adult flies trapping by McPhail traps. Proportion of infested grape bunches and berries increased as grapes maturity, harvest date approached and as increasing of C. capitata population. Linear regression equations fitted worked out and coefficient determination (R) mostly showed higher indication, hence predictions and forewarning infestation rate by pheromone traps were reliable. Control results showed, significant differences between treatments and control and most effective was spinosad (conserve) insecticide.
