Bol’shoi Ilek locality yields an edentulous fragment of the maxillary of Docodonta indet. A fragment of dentary without teeth attributed to Mammalia indet. (presumably eutriconodontan or symmetrodontan) is presented in the Berezovaya River locality. New localities fill the geographical gap between previously known mammalian localities of Ilek Formation in the basins of Kiya and Bol’shoi Kemchug rivers.
Comparative geochemical characteristics and genesis of large polystage plutons in the core and periphery of the different age areas of the Mongol-Okhotsk fold belt
Authors: Antipin V. S. , Kuzmin M. I. , Odgerel D. , Kousch L. V. , Sheptyakova N. V.
Published: August 2019

The Early Mesozoic Baga-Khentey pluton is the fragment of the Dauria-Khentey batholith, which could have formed due by the mantle plume action on lower horizons of the continental crust within the zone of collisional compression by closing of the Mongol-Okhotsk ocean. The batholith and their peripheral zones possibly formed from the mantle and crustal sources of magma. The Ikh-Narotin-Khid Massif is located on the border of the rifting zones on periphery of the Late Mesozoic area. The petrographic and geochemical affinity of granitoids of the Ikh-Narotin-Khid massif and composition of gneisses from the country rocks might indicate that this was the substratum in formation of palingenic granites of the calc-alkali series. The distinctions in rock composition of the large plutons consist in minor differentiation of the Baga-Khentey Massif rocks probably related to the anatexis conditions and origin of melts in the collisional compression setting. The granites of the Ikh-Narotin-Khid Massif formed in the extension setting favorable for deep differentiation of magmatic melts.
Feature of formation of the Black Sea surface layer temperature during air cold intrusions
Authors: Sizov A. A. , Bayankina T. M.
Published: August 2019

Application of the results of the drifter observations performed in the western Black Sea permitted to show that during air cold intrusions (CI) in winter accompanied by the wind (10 m/c and more), the upper mixed layer (UML) was cooled by 0,1-0,2 °C in course of a day. At that the seasonal thermocline (ST) and the cold intermediate water (CIW) sink deeper; after CI is over these layers rise to the depths smaller than their previous ones. It results in decrease of temperature in UML and its increase, as compared to the period preceding CI, in the layer below ST. The process of the sea upper layer mixing is explained by the fact that anti-cyclonic mesoscale vortices are involved in it.

Authors: Faris Hamid Abdulmahdi , Abd Lubna Mohammed
Published: August 2019

The "flat slab" is a reinforced concrete slab bolstered, by a number of columns. Punching, shear is a category for collapse for reinforced concrete slabs exposed to great confined forces. In "flat slab" constructions the shear failure happens, at column bolster joints. To avoid this, collapse two methods are used, first method is increasing the column dimensions and, the other is to use drop panel if the first method leads to uneconomical, design. Two examples are used to find the effect, of column dimensions, increase on the punching shear failure of "flat slab". The first example, is a "flat slab" of span (5 by 5) m and the other is of span (6 by 6) m. The column which examined is the interior, edge and corner columns, and the interior column is the most dangerous case. It is concluded that, the increase of column dimensions are lead to avoid of punching shear failure in "flat slab" and the drop panel is enlarge the area of the critical shear perimeter and this avoiding punching shear failure.

Published: August 2019

Penyakit kolera merupakan salah satu penyakit yang sering menyerang manusia. Penyebaran penyakit ini disebabkan oleh bakteri vibrio kolera yang berkembang biak pada kotoran manusia. Program sanitasi merupakan upaya pencegahan untuk mengurangi jumlah individu terinfeksi. Model matematika yang digunakan untuk pola penyebaran penyakit tersebut adalah model Suspectible, Infected and Recovered (SIR) dengan vaksinasi, sanitasi, dan treatment. Pada model ini diasumsikan adanya tingkat perilaku perlindungan, tingkat kekebalan tubuh dan laju kematian yang disebabkan oleh penyakit. Analisis kestabilan pada model menghasilkan 2 titik ekuilibrium, yaitu titik ekuilibrium bebas penyakit dan titik ekuilibrium endemik penyakit. Masing-masing titik ekuilibrium diuji kestabilannya dengan kriteria nilai eigen dan Routh-Hurwitz. Semakin tinggi tingkat sanitasi  maupun laju kesembuhan, dapat menurunkan jumlah individu terinfeksi menjadi semakin kecil. Akan tetapi semakin tinggi laju kontak, mengakibatkan individu terinfeksi semakin besar. Penyelesaian sistem menunjukan bahwa jumlah individu untuk tiap kelompok tidak berubah sepanjang waktu

 

Cholera is a common human disease. The spread of disease is caused by the Vibrio cholera bacteria that grow in human feces. The sanitation program is a prevention effort to reduce the number of infected individuals. The mathematical model used for the spread pattern of the disease is the Suspectible, Infected and Recovered (SIR) model with vaccination, sanitation, and treatment. In this model it is assumed that there are levels of protective behavior, immune levels and mortality rates caused by disease. Stability analysis on the model produces 2 equilibrium points, namely disease-free equilibrium point and endemic equilibrium point of disease. Each equilibrium point was tested for stability using eigenvalues ​​and Routh-Hurwitz criteria. The higher the level of sanitation and the rate of recovery, can reduce the number of infected individuals to be smaller. However, the higher the contact rate, the greater the infected individual's rate. Completion of the system shows that the number of individuals for each group does not change over time.

Inductively Coupled Plasma Mass Spectrometry: Introduction to Analytical Aspects
Authors: Wilschefski Scott , Baxter Matthew
Published: August 2019

Inductively coupled plasma mass spectrometry (ICP-MS) is an analytical technique that can be used to measure elements at trace levels in biological fluids. Although older techniques such as atomic absorption and atomic emission are still in use by some laboratories, there has been a slow shift toward ICP-MS, particularly in the last decade. As this shift is likely to continue, clinical scientists should be aware of the analytical aspects of ICP-MS, as well as the potential for both spectroscopic and non-spectroscopic interference, and strategies that can be employed to eliminate or mitigate these issues.
ASSESSING THE INFLUENCE OF SERVICE RECOVERY STRATEGIES ON DISTRIBUTIVE JUSTICE IN HIGHER EDUCATION INSTITUTIONS
Authors: Msosa Steven K. , Govender Jeevarathnam P.
Published: August 2019

In recent times, students in higher education institutions have raised their expectations and are becoming less tolerant to poor service. The reality is that service failures are bound to happen. However, effective service recovery strategies could minimise the impact of service failure. The aim of this research was to analyse the influence of service recovery strategies on distributive justice in higher education institutions. A total of 430 students from three public universities in South Africa participated in this research as respondents. The research adopted a quantitative, descriptive and cross-sectional approach. The findings of this research showed that compensation and explanation have a positive and significant influence on distributive justice. Furthermore, the results showed a positive and insignificant influence of apology on distributive justice. The findings of this research are a wake up call to higher education institutions to focus on the two strategies of service recovery, namely explanation and compensation to achieve distributive justice. Thus, higher education institutions should firstly, focus on the use of an explanation to achieve distributive justice because it is offered at no cost compared to compensation which normally wears a financial face. This is based on the fact that higher education institutions are non profit making institutions such that they cannot afford to offer financial compensation on regular basis to address student problems. Ultimately, higher education institutions are advised to consider the severity of service failure before offering any form of service recovery to avoid double deviation.
Keywords: distributive justice, field-based research, higher education institutions, service failure, service recovery strategies.

Assessing Contingent Convertible Bonds for Bank Recapitalization in Nigeria
Authors: Katata Kabir
Published: August 2019

This study estimates the parameters of credit derivatives, equity derivatives and structural models for bank recapitalisation in Nigeria by employing contingent convertibles (CoCos) and using the Nigeria Treasury Bill rate for 2009 as the risk-free rate, estimated recapitalisation requirements for the banks as at 2009 and relevant banks’ share prices for 2008 and 2009. The study finds the structural approach as the preferred model for CoCo pricing, as it reported the least pricing errors and also builds asset values of the banks from publicly-available quoted stock prices as well as deposit components of bank’s balance sheet information. The study also finds that CoCo bonds are likely to be fully subscribed when issued given the high stock price volatility coupled with high credit spreads in Nigeria. The paper suggests that CoCos could have been issued by the banks to recapitalise themselves without the need for regulatory actions. Therefore, usage of CoCos by banks can reduce the possibility of a bailout with public funds and lessen regulatory actions, if properly implemented, to boost the troubled banks’ capital.

Background: Nurses have a key role in promoting patients’ involvement in decision-making process of palliative care to improve their dignity and satisfaction. However, there is a dearth of studies exploring this involvement, especially in public health centers in Indonesia.

Objective: This study aimed to explore the perception of nurses in decision-making process and to understand what type of decision-making made by health care providers in palliative care.

Methods: This was a descriptive explorative study with qualitative approach. Participants were selected using purposive and snowball sampling. Data were collected using Focus Group Discussion (FGD) and in-depth interview. Content analysis method by inductive approach was used for data analysis. Consolidated criteria for reporting qualitative research (COREQ) was also used.

Results: Eight themes emerged in this study, namely: (1) Collecting information about patients’ current physiological condition, (2) Creating alternative strategies according to the patients’ current physiological condition, (3) Establishing implementation type to be performed, (4) Providing information to the patients, (5) Discussing decision-making between patients and family, (6) Choosing/rejecting an action by patients,  (7) Performing selected actions, and (8) Evaluating action. Three points that are different from the existing theory were: (i) there was a discussion between patients and family, (ii) the absence of the process of collecting information after a patient rejects to act, and (iii) there were three types of decision-making: paternalistic, shared, and informed decision-making.

Conclusion: This study serves as an input for nurses to pay more attention in decision-making process in palliative care in patients with cancer, and to encourage patients to give contribution in decision-making as part of shared decision-making.

Ensuring the food and nutritional demand of the ever-growing human population is a major sustainability challenge for humanity in this Anthropocene. The cultivation of climate resilient, adaptive and underutilized wild crops along with modern crop varieties is proposed as an innovative strategy for managing future agricultural production under the changing environmental conditions. Such underutilized and neglected wild crops have been recently projected by the Food and Agricultural Organization of the United Nations as ‘future smart crops’ as they are not only hardy, and resilient to changing climatic conditions, but also rich in nutrients. They need only minimal care and input, and therefore, they can be easily grown in degraded and nutrient-poor soil also. Moreover, they can be used for improving the adaptive traits of modern crops. The contribution of such neglected, and underutilized crops and their wild relatives to global food production is estimated to be around 115–120 billion US$ per annum. Therefore, the exploitation of such lesser utilized and yet to be used wild crops is highly significant for climate resilient agriculture and thereby providing a good quality of life to one and all. Here we provide four steps, namely: (i) exploring the unexplored, (ii) refining the unrefined traits, (iii) cultivating the uncultivated, and (iv) popularizing the unpopular for the sustainable utilization of such wild crops as a resilient strategy for ensuring food and nutritional security and also urge the timely adoption of suitable frameworks for the large-scale exploitation of such wild species for achieving the UN Sustainable Development Goals.
Factors Affecting Capacity Design of Lithium-Ion Stationary Batteries
Authors: Chang Choong-koo
Published: August 2019

Lead-acid batteries are currently the most popular for direct current (DC) power in power plants. They are also the most widely used electric energy storage device but too much space is needed to increase energy storage. Lithium-ion batteries have a higher energy density, allowing them to store more energy than other types of batteries. The purpose of this paper is to elaborate on the factors affecting the capacity design of lithium-ion stationary batteries. Factors that need to be considered in calculating the capacity of stationary lithium-ion batteries are investigated and reviewed, and based on the results, a method of calculating capacity of stationary lithium-ion batteries for industrial use is proposed. In addition, the capacity and area required for replacing the lead-acid batteries for nuclear power plants with lithium-ion batteries are reviewed as part of this case study.
A Deep Learning approach for Diagnosis of Mild Cognitive Impairment Based on MRI Images
Authors: Taheri Gorji Hamed , Kaabouch Naima
Published: August 2019

Mild cognitive impairment (MCI) is an intermediary stage condition between healthy people and Alzheimer’s disease (AD) patients and other dementias. AD is a progressive and irreversible neurodegenerative disorder, which is a significant threat to people, age 65 and older. Although MCI does not always lead to AD, an early diagnosis at the stage of MCI can be very helpful in identifying people who are at risk of AD. Moreover, the early diagnosis of MCI can lead to more effective treatment, or at least, significantly delay the disease’s progress, and can lead to social and financial benefits. Magnetic resonance imaging (MRI), which has become a significant tool for the diagnosis of MCI and AD, can provide neuropsychological data for analyzing the variance in brain structure and function. MCI is divided into early and late MCI (EMCI and LMCI) and sadly, there is no clear differentiation between the brain structure of healthy people and MCI patients, especially in the EMCI stage. This paper aims to use a deep learning approach, which is one of the most powerful branches of machine learning, to discriminate between healthy people and the two types of MCI groups based on MRI results. The convolutional neural network (CNN) with an efficient architecture was used to extract high-quality features from MRIs to classify people into healthy, EMCI, or LMCI groups. The MRIs of 600 individuals used in this study included 200 control normal (CN) people, 200 EMCI patients, and 200 LMCI patients. This study randomly selected 70 percent of the data to train our model and 30 percent for the test set. The results showed the best overall classification between CN and LMCI groups in the sagittal view with an accuracy of 94.54 percent. In addition, 93.96 percent and 93.00 percent accuracy were reached for the pairs of EMCI/LMCI and CN/EMCI, respectively.
Current Status of Gene Therapy in Hepatocellular Carcinoma
Authors: Reghupaty Saranya Chidambaranathan , Sarkar Devanand
Published: August 2019

Hepatocellular carcinoma (HCC) is the fifth most common cancer and the second leading cause of cancer related deaths world-wide. Liver transplantation, surgical resection, trans-arterial chemoembolization, and radio frequency ablation are effective strategies to treat early stage HCC. Unfortunately, HCC is usually diagnosed at an advanced stage and there are not many treatment options for late stage HCC. First-line therapy for late stage HCC includes sorafenib and lenvatinib. However, these treatments provide only an approximate three month increase in survival. Besides, they cannot specifically target cancer cells that lead to a wide array of side effects. Patients on these drugs develop resistance within a few months and have to rely on second-line therapy that includes regorafenib, pembrolizumab, nivolumab, and cabometyx. These disadvantages make gene therapy approach to treat HCC an attractive option. The two important questions that researchers have been trying to answer in the last 2–3 decades are what genes should be targeted and what delivery systems should be used. The objective of this review is to analyze the changing landscape of HCC gene therapy, with a focus on these two questions.
Weighting Factor Selection of the Ensemble Model for Improving Forecast Accuracy of Photovoltaic Generating Resources
Authors: Kim Kihan , Hur Jin
Published: August 2019

Among renewable energy sources, solar power is rapidly growing as a major power source for future power systems. However, solar power has uncertainty due to the effects of weather factors, and if the penetration rate of solar power in the future increases, it could reduce the reliability of the power system. A study of accurate solar power forecasting should be done to improve the stability of the power system operation. Using the empirical data from solar power plants in South Korea, the short-term forecasting of solar power outputs were carried out for 2016. We performed solar power forecasting with the support vector regression (SVR) model, the naïve Bayes classifier (NBC), and the hourly regression model. We proposed the ensemble method including the selection of weighting factors for each model to improve forecasting accuracy. The forecasted solar power generation error was indicated using normalized mean absolute error (NMAE) compared to the plant capacity. For the ensemble method, the results of each forecasting model were weighted with the reciprocal of the standard deviation of the forecast error, thus improving the solar power outputs forecast accuracy.

Published: August 2019

In the light of the alarming impending energy scene, energy efficiency and exergy efficiency are unmistakably gathering momentum. Among efficient process design methodologies, literature suggests pinch analysis and exergy analysis as two powerful thermodynamic methods, each showing certain drawbacks, however. In this perspective, this article puts forward a methodology that couples pinch and exergy analysis in a way to surpass their individual limitations in the aim of generating optimal operating conditions and topology for industrial processes. Using new optimizing exergy-based criteria, exergy analysis is used not only to assess the exergy but also to guide the potential improvements in industrial processes structure and operating conditions. And while pinch analysis considers only heat integration to satisfy existent needs, the proposed methodology allows including other forms of recoverable exergy and explores new synergy pathways through conversion systems. A simple case study is proposed to demonstrate the applicability and efficiency of the proposed method.

Background: Older adults experience physical and psychological declines affecting independency. Adapted and structured combined interventions composed of cognitive stimulation and physical exercise contribute to comorbidities’ reduction. Methods: Multicenter single-blinded two-arm cluster randomized controlled trial conducted to assess effectiveness of a combined intervention (CI), composed of a cognitive stimulation program (CSP) and a physical exercise program (PEP), on psychological and physical capacities of frail older adults as to on their activities of daily living. Were recruited 50 subjects from two elderly end-user organizations. Of these, 44 (65.9% females, mean age of 80.5 ± 8.47 years) were considered eligible, being randomly allocated in experimental (EG) or control group (CG). Data collected at baseline and post-intervention. EG received CI three times a week during 12 weeks. CG received standard care. Non-parametric measures were considered. Results: At baseline, groups were equivalent for study outcomes. The comparison of pre- and post-intervention data revealed that subjects receiving CI reduced depressive symptomatology and risk of fall based on gait and balance, and improved gait speed. Simultaneously, in the CG a significant decline on activities of daily living was observed. Significant results were found among biomechanical parameters of gait (BPG). EG’ effect size revealed to be small (0.2 ≤ r < 0.5). CG’ effect size was also small; but for activities of daily living there was an evident decrease. Conclusion: The CI is effective on managing older adults’ psychological and physical capacities.
Roaming the Neighbourhood: Influences of Independent Mobility Parenting Practices and Parental Perceived Environment on Children’s Territorial Range

Children’s independent mobility (IM), their freedom to move about their neighbourhood without supervision by adults, has been in steady decline in recent decades. Previous research has linked perceptions of the environment with various measures of IM, but recently concerns have been raised regarding inconsistency in measuring IM. This study used various measures of IM and aimed to address how parental perceptions of the neighbourhood environment are associated with children’s territorial range (actual IM), as well as how this relationship is mediated by IM parenting practices (allowed IM). A sample of 105 child/parent dyads from Vancouver, Canada participated in this study. Children (age 10–13) wore a global positioning system (GPS) watch and an accelerometer and completed an activity diary for seven days to assess their territorial range. Parents completed a questionnaire that assessed perceptions of their neighbourhood environment and IM parenting practices—license for IM and roaming allowance. Path analyses were used to address the research aims. License for IM and roaming allowance mediated the relationship between perceived walking facilities, crime safety, and neighbourhood relations and children’s territorial range. Findings suggest that future interventions to increase children’s territorial range should focus primarily on attitude and behaviour change among parents to grant children more freedom.

Spirometric restriction in herbicide-exposed U.S. Army Chemical Corps Vietnam War veterans was examined because no published research on this topic in Vietnam War veterans exists. Spirometry was conducted on 468 veterans who served in chemical operations in a 2013 study assessing the association between chronic obstructive pulmonary disease (COPD) and herbicide exposure. Exposure was verified based on blood serum values of 2,3,7,8-tetrachlorodibenzo-p-dioxin. Further, the association between herbicide exposure and spirometry restriction (forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) ≥ lower limit of normal (LLN) and FVC < LLN) was tested after adjustment for military characteristics, selected anthropometrics, and other predictors using multivariable regression. Spirometric restriction in herbicide sprayers (15.7%, 95% CI: 10.6, 20.9) was almost twice that of nonsprayers (9.91%, 95% CI: 5.9, 13.9) (p = 0.081). While spirometric restriction was not significantly associated with herbicide exposure (adjusted odds ratio (aOR) = 1.64, 95% CI: 0.82, 3.29) despite the greater prevalence of restriction in sprayers versus nonsprayers, spirometric restriction was significantly associated with race/ethnicity (aOR = 3.04, 95% CI: 1.36, 6.79) and waist circumference (aOR = 2.46, 95% CI: 1.25, 4.85). Because restrictive pulmonary disease may result from chemically-induced inflammation or sensitivity, research on chemical exposures and restriction in veterans should continue. Future study should include full pulmonary function testing, targeted research designs, and a wider set of explanatory variables in analysis, such as other determinants of health.
