Estimation of Calorific Values of Some of the Turkish Lignites by Artificial Neural Network and Multiple Regressions
Authors: Özdemir Engin , Sarici Didem Eren 
Published: November 2019

Background:
The calorific value is the most important and effective factors of
lignites in terms of energy resources. Humidity, ash content, volatile matter and sulfur content
are the main factors affecting lignite's calorific values.

Objective:
Determination of calorific value is a process that takes time and cost for businesses.
Therefore, estimating the calorific value from the developed models by using other
parameters will benefit enterprises in term of time, cost and labor.

Method:
In this study calorific values were estimated by using artificial neural network
and multiple regression models by using lignite data of 30 different regions. As input parameters,
humidity, ash content and volatile matter values are used. In addition, the mean
absolute percentage error and the significance coefficient values were determined.

Results:
Mean absolute percentage error values were found to be below 10%. There is a
strong relationship between calorific values and other properties (R2> 90).

Conclusion:
As a result, artificial neural network and multiple regression models proposed
in this study was shown to successfully estimate the calorific value of lignites without performing
laboratory analyses.
Steel Corrosion and Control in Concrete Made with Seawater
Authors: Goyal Arpit , Karade S.R. 
Published: November 2019

Background:
Water scarcity is amongst the biggest problems the world is facing in the 21st
century. To reduce the consumption of Potable Water (PW) in construction industries and to make
concrete construction more sustainable, its replacement with Seawater (SW) has been explored. Technical
literature on this subject is not widely available. Such investigations are necessary for determining
suitable remedial measures for the effective utilization of seawater for making sustainable concrete.

Objective:
In the present study, use of Seawater (SW) has been explored as both mixing and curing
water in concrete. To counter the adverse effects of seawater on strength and corrosion resistance, use of
Fly Ash (FA) and Red Mud (RM) as cement replacements in the seawater concrete had been investigated.

Methods:
The possibility of the use of seawater in making concrete has been explored by literature
and experimental investigations. The obtained results are discussed in light of the information available
in the literature. Various tests were performed such as compressive strength, Half-cell potential,
electrochemical impedance spectroscopy and microstructural analysis using SEM and XRD.

Result:
Results showed higher compressive strength and improved corrosion resistance for Seawater
Concrete (SWC) with FA & RM as compared to Potable Water Concrete (PWC) specimens. SWC
specimens without supplementary cementitious materials show lower electrical resistivity and potential
more negative than -450 mV indicating severe corrosion. 30% FA and 5% RM is identified as the
optimum combination for the most favorable response in terms of mechanical strength and electrical
resistivity of seawater concrete. After 90 days, the compressive strength of 35.77 MPa was achieved.

Conclusion:
Combination of both FA and RM in SWC reduces chloride migration and increases chloride
binding by the formation of Friedel’s salt. Half-cell potential (HCP) and Electrochemical Impedance Spectroscopy
(EIS) results confirmed a reduction in corrosion rate in SWC specimens with fly ash and red mud.

The widespread and prolonged violent conflict in Aceh has passed down negative legacy within a vulnerable communities. One of the most-exposed the social capital elements is the mutual trust or the excessive manifestation of hate. Although suspicion often provides a sense of security in violent conflict, yet when peace is present, the inherent feeling of distrust can disrupt the construction of community coexistence towards reconciliation. However, with the development of a fairly massive coffee culture, promising opportunities to construct coexistence in post-conflict societies in Aceh emerged. Therefore, this study uses a narrative approach in describing the potentials of coffee culture in constructing the coexistence of post-conflict communities in Aceh.

Improving the quality of liquid insulation of oil-filled electrical equipment by introducing new additives
Authors: Gainullina L. R. , Tutubalina V. P. 
Published: November 2019

Stable and reliable operation of oil-filled electrical equipment at power facilities depends largely on the quality of liquid insulation — transformer oil, which is influenced by environmental and operational factors, as a result of which it is flooded, aging with precipitation and oxidation products, which leads to short circuits and breakdowns. About 85% of transformer failures are due to a violation of the insulation system. To increase the service life of transformer oil, it is traditionally added an antioxidant additive ionol, the drawback of which is its high sensitivity to organosulfur compounds. Improving the quality of transformer oil is possible due to a more effective antioxidant additive. Previous studies have shown the ambiguous effect of organosulfur compounds on the performance of transformer oil. In this regard, as well as taking into account an increase in the production and processing of sulfur and sour crude oils, the effect of individual sulfides of various structural group composition on operational indicators, such as stability indicators against oxidation of the oil fraction, saponification number, ether number, absorbed oxygen amount, and corrosion activity, was studied at operating temperatures and in an electric field of 30 kV/cm.During the study, it was found that cyclohexyldecylsulfide is the most active inhibitory additive to the oil fraction among individual organosulfur compounds. However, diphenylsulfide and diphenyldisulfide reduce stability against oxidation of the fraction, worsening its quality.It was established that when aromatic cycles in a sulfide molecule are replaced by cyclohexyl cycles, the inhibitory ability increases, increasing the quality of transformer oil and, accordingly, the reliability of operation of electrical equipment as a whole.
Assessment of farmer’s awareness of agricultural insurance packages: evidence from “Farming is our pride” communities of Zamfara State, Nigeria
Authors: Jatto Ayoyinka Nurudeen 
Published: November 2019

Abstract
Agricultural insurance has been one of the most crucial instruments in modern agricultural value chain financing. This study assesses farmer’s awareness of agricultural insurance packages available in the farming communities of Zamfara State. The study uses a primary source of data collected through a structured questionnaire. From the ten listed common crops majorly grown in the state, ten farmers were purposively selected from each association to make up 100 farmers for the study. The results showed that the majority of the farmers were males with mean age of 40 years and they were educated. Majority of the farmers were married, most of them having a mean family size of seven persons, average farm size of three hectares, average farm experience of about 16 years and majority (61 %) was combining farming with other occupation. Most of the respondents belonged to a cooperative society with eight years of membership. The binary logistic regression showed that the only factor responsible for farmers' awareness of agricultural insurance packages is membership in a cooperative society. It was concluded that farmers' awareness of agricultural insurance packages is significantly influenced only by membership of cooperative association. It is recommended that policy makers, agricultural insurance firms, and other actors in agricultural activities should put cogent effort in awareness and symposiums on agricultural insurance packages to enable farmers be aware of different agricultural insurance packages that can mitigate the uncertainty they face in their agricultural activities.

Authors: Peedosaar Laura , Põldveer Eneli , Kollo Joonas , Kangur Ahto 
Published: November 2019

Abstract
With the rapid development in data acquisition and presentation, there is a growing interest in virtual forests and computer visualization tools. Forest owners have become more aware about their property and are interested in applying different forest management methods and silvicultural techniques. The tools are also applicable in assessment of the changes to the landscape as a result of natural and anthropogenic disturbances. Virtual reality offers a good opportunity to test and compare different management options before implementing decisions which can lead to irreversible consequences. Advances in spatial and temporal data collection enable new and practical solutions for analysis and visualization of long-term natural processes with new forestry applications. In the near future, forest owners and managers will have the possibility to make management decisions without the direct need to exit the office. Furthermore, the learning process is more enthralling and also more profound through augmented reality, helping to foster better working practices even before starting a job in the forest sector.

Abstract
Vitamin D is known to affect the functions of pancreatic beta cells, but the effects of vitamin D deficiency on glucoregulatory mechanisms are still inconclusive. The aim of this study was to link vitamin D levels with parameters of insulin resistance and insulin secretion. The study included 70 male and female participants, 40 newly diagnosed patients with type 2 diabetes mellitus (T2DM) and 30 healthy controls. All participants were tested for fasting glucose, hemoglobin A1c, fasting insulin, vitamin D levels, and the HOMA indexes were calculated using HOMA2 calculator. Fasting glucose levels, insulinemia, hemoglobin A1c levels and HOMA IR were all significantly higher in the diabetic group (p<0.001), while vitamin D levels and HOMA S index were significantly lower (p<0.001). HOMA-B values did not differ between the two groups (p=0.31). Vitamin D levels moderately correlated with HOMA S and HOMA B indexes (r=0.466, p<0.001; r=0.394, p<0.001, respectively), whereas a negative correlation was found between vitamin D levels and HOMA IR (r=−0.285; p<0.001). Multiple regression analysis showed that vitamin D levels significantly predicted the values of HOMA B index (p=0.001), but they had no predictive value on HOMA IR (p=0.26). In conclusion, the group of newly diagnosed patients with T2DM showed significantly lower vitamin D values compared to the healthy control group. The connection between vitamin D, glucose levels, hemoglobin A1c and insulin secretion index underlines the role of this vitamin in glucoregulation.

Published: November 2019

Abstract
Healthcare professionals should serve as promoters of rational antibiotic use in attempt to decrease antibiotics misuse within the process of self-medication. Current pilot study was undertaken with the aim to identify potential predictors of self-medication with antibiotics (SMA) and to describe SMA practice among nursing students in Serbia. Data have been collected during the period March-May, 2016 in Medical school of bachelor degree, in Belgrade. Self-reported questionnaire served as a data source. Descriptive statistic was used to analyse study sample characteristics. Chi-square test was used to test differences between groups. Study sample have included 138 participants. Almost half of them, 43.8%, practice SMA. Life style (smoking, alcohol consumption, sleeping habits and physical activity) and socio-demographic characteristics (excepted school grade) were not shown as SMA determinants. Time & money savings were stated as the most frequent reason for SMA, while common cold, sore throat and cough were the most common conditions cured through SMA. Pharmacists’ recommendations and previous positive experience were specified as the most important in the process of antibiotics selection, indicated by 50.0% and 37.5% participants, respectively. Amoxicillin was the most frequently used antibiotic in SMA, used by 50% of participants who practice SMA. High proportion of SMA and observed practice among nursing students in Serbia call for efforts with regards to relevant education about rational antibiotic use, actual clinical guidelines and potential consequences of misuse.

Published: November 2019

Abstract
One of the key elements for rural development is the connectivity using proper roads, which enhances the passage for economic and social utilities with overall socio-economic development. Socio-economic impact assessment (SEIA) forms one of the significant measures to evaluate the outcome received through infrastructure development in rural areas. SEIA modeling under computational intelligence coupled with fuzzy framework provides significant ground to deal with both qualitative and quantitative data. This study proposes a novel methodology by using Adaptive Neuro-Fuzzy Inference System (ANFIS) with Fuzzy Delphi method (FDM) to evaluate socio-economic impacts. The effectiveness of the methodology is presented through a case study for 27 habitations connected with all-weather rural roads constructed under Pradhan Mantri Gram Sadak Yojana (PMGSY) scheme in Jhunjhunu district of Rajasthan State, India. 33 key-parameters under five different criteria are considered for SEIA. For a comprehensive view of the impacts, the results are depicted using ArcGIS tool.

Published: November 2019

Abstract
Information and communication technology (ICT) has revolutionized almost all aspects of human life. Thus, examining the effect of this technology on social problems such as traffic congestion, environmental pollution, urban design, land use etc. is of immense importance for transportation planning. Using 303 questionnaires completed correctly by residents of Tehran, this study applied Structural Equation Modelling to investigate the effect of ICT usage in a broader definition on 27 types of out-of-home activities, which were classified into three categories of subsistence, maintenance and leisure activities. The results showed the complementary/generation effect of ICT usage on travel demand. The use of ICT was also found to increase the time spent on subsistence activities and decrease the time spent on maintenance activities, as out-of-home maintenance activities can be carried out more easily and rapidly by Internet, and so people naturally prefer to follow this approach.

Published: November 2019

Background:
Following spine surgery, different types of inhalational anesthetic agents can result in postoperative delirium (POD) that can increase perioperative/postoperative morbidity. Here, we compared the incidence of POD in adults undergoing spine surgery anesthetized with isoflurane versus desflurane.

Methods:
A prospective randomized double-blind clinical trial for patients undergoing spinal surgery was performed in 60 adults (aged 18–65 years); they were randomized to receive isoflurane or desflurane. On postoperative days 1 and 3, the diagnosis and severity of POD utilized 3D-Confusion Assessment Method (CAM) and CAM-severity delirium severity scores to assess patients’ status. Multiple other variables which may have influenced the frequency/severity of POD were also studied.

Results:
For the two groups, the incidence of POD utilizing isoflurane and desflurane was similar on postoperative days 1 (10% vs. 13.3%, P > 0.05) and 3 (6.6% vs. 0%, P > 0.05). The severity scores of POD for both anesthetic agents were also similar on postoperative days 1 (1.5 vs. 1) and 3 (0.5 vs. 0.5). In addition, there was no significant association of POD with other perioperative factors.

Conclusion:
A significant number of patients undergoing spine surgery experience POD. However, the incidence and severity of POD remained similar when utilizing either isoflurane or desflurane.
