Published: December 2020

The experimental verification of the calculated flash point temperatures of solvent mixtures used in industry is presented, and the evaluation of the adequacy of the methods for calculating the rate of its evaporation is given. To verify these methods, acetone-benzene and acetone-chloroform mixtures were experimentally studied, for which a deviation from Raoult's law could be assumed. The dependences of the evaporated substance on time at room temperature are obtained. An increase in the saturated vapor pressure and an increase in the evaporation rate are observed in the first mixture, and a decrease in the second. In the first case, the amount of substance that is taking part in the explosion increases and must be taken into account when calculating the room pressure increase during explosion, and the second can be used to reduce the potential explosive hazard of solvent mixtures. The problem of predicting fire and explosion hazard of solvents is associated with the identification of the fact of the formation of explosive concentrations of their vapors and change of flash point temperatures of the mixed liquids. By the example of a number of binary mixtures of flammable liquids, the influence of the interaction of their components on the flash point is shown, the calculated and experimental (reference) data in a closed crucible are compared for the ratio of components in the range from 0 to 100 % in benzene-toluene and benzene-ethanol mixtures. It is noted that for mixtures with a similar molecular structure, the results of calculating the flash point are in good agreement with the experiment, otherwise, the calculation gives overestimated values for liquids of various classes. Therefore, for mixtures of solvents used in industry, the number of components of which is three or more, it is required to check the flash point experimentally in order to more accurately predict their fire and explosion hazard.

Statistics confirm the facts that the human factor is involved in the emergence of hazards in the technosphere. Its negative role is manifested in the negative effect of service personnel on the industry areas that are part of the integrated safety and security system of the enterprise. The services created at the enterprise are the guides in the implementation of the departmental requirements, and to ensure the reliable functioning of the presented industry areas (subsystems) of safety, they need high-quality organizational interaction with each other. Moreover, this applies not only to the period of the emergency, but also to the everyday conditions of the functioning of an industrial enterprise. To solve this problem, a methodological justification is presented in the application of indicators of the effect of the human factor on complex safety and security. It allows to calculate the coefficient of influence of each of the services through their managerial effect on the assigned branch area of safety. Approaches are analyzed using the existing methods of organizing the integrated safety and security of the enterprises, the features of their application are considered. At the stage of conducting analytical studies, the application of the method of direct deterministic factor analysis is proposed, which makes it possible to detail the indicators of the influence of factors, break them into components. At the stage of synthesizing the obtained analytical results, it is proposed to use the goal tree method based on the inverse calculations, which allows us to obtain the coefficients of increment (decrease) of gaps (erroneous actions) of service personnel that arise in the dynamic process of fulfilling their job functions.

Published: December 2020

Aim: Placental invasion anomalies are rare, but it causes serious fetomaternal morbidity and mortality. In our study, we aimed to evaluate the fetomaternal results of cases with Abnormal Invasive Placenta ( Placenta Percreata).

Methods: Patients who underwent a peripartum hysterectomy or whose placenta was left in uterin cavity due to placenta percreata in our hospital were retrospectively analyzed. Data of 20 patients were noted.

Results: The mean age of the patients was ± SD (min-max) 33 ± 5,704 (25-46) and 60% (n = 12) of the patients had additional diseases. Fifty five percent of patients (n=11) were operated in emergency conditions and 45% (n = 9) in elective conditions. Surgical complications were 65% (n = 13) bladder injuries, 30% (n = 6) disseminated intravascular coagulation (DIC), 20% (n = 4) infection, 15% (n = 3) relapartomy and 5% (n = 1) was pulmonary embolism. Mortality increased three times (OR; 3.003 (95% CI, 0.372-24.390) in patients with a comorbidity, while 4.7 times (OR; 4.784) in emergency operations. Operations under elective conditions and previously ultrasonographic diagnosis (Odd ratio values ; 0,219 (95% CI, 0,021-2,447) and 0,615 (95% CI, 0,043-8,695), recpectively) decreased maternal mortality.

Conclusion: Prenatal diagnosis and performing elective surgeries in percreata cases are important to reduce maternal mortality. Although there are various surgical complications, we think that DIC development is important in mortality and massive transfusion does not decrease the mortality.

Presently, scientific knowledge on the association between urinary lead concentration and renal profile is limited, especially on the characteristic of urinary lead that could aggravate existing kidney disease. This study aims to determine the concentration of urinary lead with serum creatinine and blood urea nitrogen in chronic kidney disease patients and to identify the influences of confounding factors and the blood pressure on the chronic kidney disease patients. Graphite Furnace Atomic Absorption Spectrometer was used to determine the urinary lead concentration. The differences and correlation of urinary lead with serum creatinine, blood urea nitrogen and diastolic blood pressure between the chronic kidney disease patients and control groups were assessed using Mann Whitney U and Spearman correlation tests. Our findings indicated a significantly higher urinary lead concentration in the chronic kidney disease group compared to the control group (p-=0.002). Nevertheless, there is a weak relationship between urinary lead with serum creatinine, blood urea nitrogen and diastolic blood pressure in the chronic kidney disease group (r values: -0.123, 0.101, and 0.127). In addition, sociodemographic factors did not influence the concentration of urinary lead (p>0.05). The urinary lead concentration in the chronic kidney disease group is not substantial, thus the evidence of urinary lead accumulation in chronic kidney disease group who have yet to start renal replacement therapy is inconclusive.

Published: December 2020

This paper presents the results of a geophysical investigation of groundwater quality in parts of Akwa Ibom State, Southern Nigeria. A total of 11 vertical electrical soundings (VES) was carried out in the study area using the Schlumberger electrode configuration. The results of the interpretation show that the area comprises 4 geoelectric layers. The third layer constitutes the major economic hydrogeological unit in the area and has resistivity of between 50.3 Ωm and 2088.9 Ωm and thickness of between 36.8 m and 149.0m respectively. The groundwater quality was assessed through estimates of the electrical conductivity and total dissolved solids in water. The conductivity ranges from 74.5 to 604.4µS/cm with an average value of 244.0µS/cm while the TDS values range from 47.7 to 386.8 ppm with an average value of 156.1 ppm. Based on these values, which are within the permissible limits, the water is considered to be fresh and suitable for drinking and other domestic/agricultural usages. The results show excellent correlation between the estimated TDS and the Dar-zarrouk parameters (longitudinal conductance and transverse resistance) on one hand and the aquifer bulk resistivity on the hand which demonstrate the ease of deriving TDS from surface resistivity data.
SEISMO – IONOSPHERIC INDUCED PERTURBATIONS PRIOR TO THE SEPTEMBER 28, 2007 M7.5 NORTHERN MARIANA U.S.A. GEOQUAKE FROM GPS, TEC AND DEMETER DATA
Authors: Thomas Jewel E.
Published: December 2020

Data from DEMETER (IAP and ISL sensors) and GPS (TEC), were used to decipher variations of electron density, electron temperature and ion density within the seismogenic zone of a seismic event that occurred on September 28, 2007 at Northern Mariana U.S.A, through statistical analysis. The study revealed both pre and post ionospheric perturbations from both sets of data. The observed anomalous variations were screened for false alarm using the geomagnetic indices of kp and Dst. It was observed that the abnormal TEC on -10, – 7, -3 and -2 days occurred under quiet geomagnetic conditions while all pre-seismic (-15, -10, – 9 -7 days) ionospheric variations from the DEMETER data were also obtained during quiet geomagnetic conditions suggesting them to be seismo-ionospheric induced perturbations. Interestingly, the perturbations on -10 and -7 days were simultaneously observed from both GPS and DEMETER datasets under quiet geomagnetic ionospheric conditions offering a strong pointer to the impending geo-quake.
ASSESSMENT OF SOIL EROSION BY RUSLE MODEL USING GIS: A CASE STUDY OF CHEMORAH BASIN, ALGERIA
Authors: K. Khanchoul , F. Balla , O. Othmani
Published: December 2020

Soil erosion by water is one of the major sources of land degradation. Erosion contributes to the temporary or permanent lowering of the productive capacity of agricultural land and sedimentation of dams. The purpose of this study is to assess soil loss rate using a GIS/RUSLE approach at the Chemorah basin by focusing on two catchments, namely, Reboa and Soultez. The assessment of soil erosion aims thus to identify the lands more prone to erosion which are vital for erosion management process. RUSLE model supported by GIS software is to predict the spatial variability of erosion occurring in the Chemorah basin and its sub-basins. Five inputs such as rainfall erosivity, soil erodibility, slope and length of slope, plant cover and anti-erosion practices, are used in the model to compute the erosion loss rates. The mean annual soil loss in Chemorah river basin is estimated at 7.52 T/ha/year, and varying between 3.78 T/ha/year in Soultez catchment and 6.06 T/ha/year in Reboa sub-basin. The study shows that low erosion (≤ 7 T/ha/year) covers 52% and high to very high erosion (> 7 T/ha/year) which does not exceed 23% of the Chemorah basin area. The results indicate that Reboa catchment faces the greatest risk of soil erosion compared to Soultez one, with contributions of 44 % and 32 % of their basin areas respectively. Use of the erosion factors’ information coupled with GIS/RUSLE program can help to design the appropriate land management to minimize soil erosion in the basin.

Published: December 2020

This work presents the interpretation of the aeromagnetic data over Soko and Ankpa area using spectral analysis method. The study area was divided into eight (8) equal spectral blocks in order to estimate the depth to the top boundary, centroid, Curie point depth, heat flow and geothermal gradient of the study area. The result of the analysis shows the range of the depths to the top boundary and centroid varies between 1.085 to 1.984 km and 6.151 to 8.730 km respectively. The Curie temperature isotherm ranges between 11.112 km and 15.476 km and the geothermal gradients associated with it ranges from 39.967 and 52.196 0 𝐶⁄𝑘𝑚. The corresponding values of heat flow ranges from 93.697 𝑚𝑊𝑚􀀀 and 130. 49􀀁 𝑚𝑊𝑚􀀀. From this analysis, it was observed that areas with high geothermal gradient correspond to high heat flow and an inverse relationship exists between the heat flow and the Curie point depth. With the high geothermal gradient especially at the southeastern part of the study area, there is a possibility of enough geothermal energy for exploration in order to boost and generate clean energy for electricity.

Published: December 2020

Nepal faces a significant risk of invasive species posing a direct threat to food security and native biodiversity. With the potentiality of causing a considerable loss in yield and quality, invasive pest species can lead to significant damage in the Nepalese agricultural sector. Fall armyworm is a polyphagous, transboundary invasive pest that invaded Nepal in August 2019. They have a wide host range, the potentiality to establish rapidly and are highly migratory. Maize is the major host of fall armyworm which comes second in terms of production and area cultivated in Nepal. Spread and establishment of this pest are enhanced during the monsoon season of the country with favorable climate and temperature. This review presents an introductory pathway of the invasive pest, biology, lifecycle, status, and management of fall armyworm in Nepal. Integrated pest management can be the best approach for the management of this pest. Control of this invasive pest requires early monitoring, scientific research, and management strategy with awareness, knowledge, and technical support to Nepalese farmers.

Beekeeping with Apis cerana is a vehicle to run livelihood of rural farmers in Nepal. Honey production is major source of cash income for them. This study was conducted in Dang, Nepal, with the aim to analyze production and marketing economics of honey form A. cerana. Total 55 beekeepers, two beekeeping groups, two collectors and five retailers were selected randomly for interview. The results showed that on average farmers holding 14.55 bee hive with productivity of honey 6.12 kg per hive. The benefit cost ratio was 3.71 and average annual net profit was NRs. 2,646.96 (USD 23.06) per hive. Human labour hours in colony management, number of beehives and number of honey harvest per year were significant factors affecting honey production. Ninety two percent of honey produce was actually marketed through three major marketing channels. Most of the producers directly sold honey to consumer and had higher farm gate price. Overall farm gate price, price spread, producer’s share and marketing efficiency index of honey was NRs. 671.06/kg, NRs. 93.15/kg, 84.12 percent and 5.30 respectively. Absconding behavior of A.cerana was the top production problem and lack of wholesale marketing points was top most marketing problem perceived by farmers.

Published: December 2020

Radiotherapy is one of the most important treatment methods of cancer, which is the worldwide disease nowa-days. It is essential to protect the critical organs and healthy tissue inside the radiated area during the radiotherapy. For this reason, Cerrobend block (lipowitz alloy), which is made specifically for each patient, are commonly used in the hospitals. In the clinical application, the acceptable level of the gamma-ray transmission for Cerrobend blocks must be less than 5%. In this research, GEANT4 based GATE simulation program modelled to compare between gamma-ray transmissions of the standard Cerrobend block and newly designed Cerrobend blocks formed by adding the various number of the pure lead marbles. Experimental measurements were carried out with Alcyon II model Co-60 teletherapy machine for various field sizes by using Farmer type 0,6 cc ion chamber, PTW Unidos Dosimeter and solid phantom in Dr. Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital in 2010. The gamma-ray transmission of the newly designed Cerrobend block was found less than the standard block, therefore the protection of the critical organs for the patient could be better. The dose acquired by GEANT4 based GATE simulation program is consistent in experimentally measured radiation dose. Furthermore, the values of the linear attenuation coefficient theoretically obtained from XCOM software agree with the values acquired by experiment and simulation

Memory about the 1993 Crisis and Emergence of the Russian Constitution in the Political Discourse of 2000—2010s
Authors: Malinova O.Yu.
Published: December 2020

The article continues the project devoted to framing the memory of the “nineties” in the Russian political discourse. It examines one of the most dramatic moments in the history of the post-Soviet transformation — the political crisis of 1993, which resulted in adopting the Constitution that formally is still in use today. The author examines the process of framing the memory of the events of 1993, analyzing publications of the federal print media in the post-Yeltsin period. She focuses on three time periods that reflect different stages in the development of the Russian polity — the tenth, twentieth and twenty-fifth anniversaries of the crisis, which makes it possible to trace the evolution of the revealed narratives. The analysis shows a noticeable change in the official discourse when V.Putin became a President — the narratives proposed by B.Yeltsin about the victory of the reformers over the counter-reforms and the suppression of an armed rebellion / prevention of civil war were discarded, while the main attention shifted to the Constitution as a “historic choice of the Russian people”. At the same time, Putin uses the dramatic events of 1993 to emphasize the current “stability”, which is supposed to be the main achievement of his rule. The narratives articulated by the communists and other successors of the memory of the defenders of the White House have not undergone significant changes. The author explains it by the fact that for this ideological segment the events of 1993 represent a “myth of the foundation” of Putin’s regime. In liberal discourse, critical versions of the crisis narrative eventually trumped the apologetic ones. In recent years it has become especially clear that liberals and communists tend to converge on their interpretation of the consequences of the crisis (but not its causes or the assessments of the actors). However, the symbolic conflict that plays an essential role in constructing their political identities still remains.

Authors: Arrondo Guillermo , Gómez Daniel , Joannas Germán , Martín-Oliva Xavier , Iglesias Matías , Casola Leandro
Published: December 2020

Objective: Impingement syndromes are recognized as an important cause of chronic ankle pain, which results from the entrapment of an inflamed soft-tissue component between the osteophytes. The predominant site of occurrence is the anterolateral aspect of the ankle for soft-tissue impingement, and anteromedial aspect for bony impingement. Symptoms related to the physical impact of bone or soft-tissue pain often result in limited ankle range of motion. Methods: We conducted a retrospective study of 34 patients (34 ankles) with anteromedial bony impingement. All patients underwent arthroscopy, with a mean follow-up of 34 months. Results: All osteophytes were removed, and the ankle range of motion improved. The AOFAS score improved from 73 preoperatively to 95 postoperatively. Conclusion: The arthroscopic removal of the anteromedial osteophytes of the ankle had excellent functional results. It is an effective procedure that allows rapid patient recovery.

Objective: This work performs a critical review of the different causes described to explain the etiopathogenesis of hallux valgus. Methods: The authors divide the causal factors into two groups: extrinsic and intrinsic factors. In the first group, footwear and mechanical overload caused by different causes such as ballet, trauma, long walks, obesity, etc., should be considered. In the second group we include a series of factors: constitutional ones, such as heredity, sex and age; anatomical aspects, among which we must highlight the morphology and obliquity of the metatarsocuneiform joint; hypermobility of the first ray; metatarsus primus varus; muscle function; and atavism. Results: Hallux valgus probably has a multifactorial etiology whose triggering factor is unknown at the moment. Conclusion: If we know the etiopathogenesis of a deformity, in this case hallux valgus, we can perform a treatment as early and effective as possible.

Objective: To present the clinical and radiographic results of surgical treatment of patients with moderate to severe hallux valgus (HV) by minimally invasive Chevron - Akin osteotomy (MICA). Methods: The case series comprises 25 patients (30 feet) with diagnoses of moderate to severe HV treated surgically with the MICA technique. All patients answered the American Orthopedic Foot and Ankle Score (AOFAS) and rated pain on visual analogue scale (VAS) at preoperative assessment and at the last follow-up consultation. Radiological assessment included measurement of the valgus angles of the hallux (HVA) and the 1st and 2nd ray intermetatarsal angle (IMA). Complications and satisfaction ratings were also documented. Results: Mean follow-up was 14.6 months. Mean AOFAS increased from 42.8 to 90 and VAS reduced from 8.6 to 1.7. Mean HVA reduced from 31.7o to 8.4o and IMA from 14o to 5o. All these improvements were statistically significant (p<0.001). The most common complication observed was discomfort caused by hardware, affecting five feet (16.6%). Two patients (6.6%) had transitory neurapraxia and one patient (3.3%) developed reflex sympathetic dystrophy. There were no cases of infection, relapse, pseudarthrosis, or malunion of osteotomies. Subjective satisfaction ratings classified 93.3% of results as good or excellent. Conclusion: Minimally invasive Chevron-Akin osteotomy is a safe and reproducible technique that achieves good clinical and radiographic results for treatment of moderate to severe hallux valgus.

Introduction: Preeclampsia is one of the causes of maternal mortality. In preeclampsia, endothelial dysfunction triggers the emergence of inflammatory cytokines and increases the expression of the molecular adhesion of ICAM-1. Inflammation of the preeclampsia can be controlled with the administration of anthocyanins. Java plum (Syzygium Cumini) contains anthocyanins that serve as antioxidants and anti-inflammatory.

Purpose: This research aims to prove the influence of the administration of java plum (Syzygium Cumini) extracts on the expression of ICAM-1 on the model of HUVECs preeclampsia.

Method: The research is conducted experimentally. It is done within the glass in a laboratory with two control groups namely negative control, three positive control, and six experimental groups (100ppm dose, 200ppm and 400ppm, incubation 1 hour, 3 hours, and 24 hours). HUVECs preeclampsia as a model of HUVECs preeclampsia within the glass. The ICAM-1 expression is used in the immunohistochemistry. The statistical analysis uses Two Way Anova test and regression test.

Result: at the time of incubation of 1 hour, 3 hours, and 24 hours, there is no meaningful difference in the expression ICAM-1 (p = 0.392 > ∝). At the dose ICAM-1 of java plum, there is a meaningful difference between the positive control group with the dosage group of (p = 0.000 < ∝).

Conclusion: An expression of ICAM-1 increases in preeclampsia conditions, administering java plum at a dose of 100 ppm, 200 ppm, and 400 ppm may decrease the expression of ICAM-1 in preeclampsia condition.

One of the actions that can be taken to prevent hypertension is to develop knowledge about the level of vulnerability on several factors that influence it. It is expected that with enough knowledge to feel the level of vulnerability can increase awareness of hypertension. The purpose of this study was to determine the effect of the level of vulnerability on factors of sleep quality, stress, and eating patterns on hypertension in online-based transportation drivers in Kediri City. The research design used is quantitative research using the "cross sectional" approach. The sampling technique used was simple random sampling with a sample of 164 respondents. The data analysis technique uses a logistic regression multivariate test. The results showed that the sleep quality variable a significance value of 0,000 <(α = 0.05), meaning that H0 is rejected and H1 is accepted which means that there is an influence between sleep quality on the incidence of hypertension. In the stress variable it is known a significance value of 0.004 <(α = 0.05), meaning that H0 is rejected and H1 is accepted, which means that there is an influence between stress levels on the incidence of hypertension. In the variable eating patterns it is known a significance value of 0,000 <(α = 0.05), meaning that H0 is rejected and H1 is accepted which means that there is an influence between eating patterns on the incidence of hypertension. Knowledge of the level of vulnerability to the causes of hypertension can increase one's awareness of the dangers of the disease so that they can take early precautions and protect themselves from the threat of the disease.

Background: Staying at home during Covid-19 pandemic is no longer a safety aspect. During lockdown there is clustering of all the family members at home. Parents or caregivers must manage their children’s schooling as well as their own work and parenting responsibilities. Some articles mention that Covid-19 pandemic turning into “broader child crisis” such as violence against on children. Child abuse can take place in a home environment under the care of parents or other family members.

Purpose: Analyze the impact of isolation policies caused the spread of COVID-19 and evidence of child abuse during Covid-19 pandemic

Methods: This literature review is arranged based on literatures studies from 5 databases last 6 years, such as DOAJ, Google Scholar, ResearchGate, SpringerLink, and Elsevier Open Access Journals. This literature review searched for studies with the keyword “child abuse” or “child neglected” or “covid-19 pandemic impact”. Based on a search using these keywords, 8 articles were found from the data base.

Results: Building awareness about child abuse and neglect during Covid-19 pandemic is vital, because children are often vulnerable and require careful consideration by parents or caregivers and health care system. So, to protecting children from violence during Covid-19 pandemic requires all sectors to undertake coordinate measure (parents or caregiver, school, community and health profession).

Conclusion: The health profession has a duty to provide support with public health approach in overcoming about child abuse and neglect.

Through dynamic transactional processes between genetic and environmental factors, childhood and adolescence involve reorganization and optimization of the cerebral cortex. The cortex and its development plays a crucial role for prototypical human cognitive abilities. At the same time, many common mental disorders appear during these critical phases of neurodevelopment. Magnetic resonance imaging (MRI) can indirectly capture several multifaceted changes of cortical macro- and microstructure, of high relevance to further our understanding of the neural foundation of cognition and mental health. Great progress has been made recently in mapping the typical development of cortical morphology. Moreover, newer less explored MRI signal intensity and specialized quantitative T2 measures have been applied to assess microstructural cortical development. We review recent findings of typical postnatal macro- and microstructural development of the cerebral cortex from early childhood to young adulthood. We cover studies of cortical volume, thickness, area, gyrification, T1-weighted (T1w) tissue contrasts such a grey/white matter contrast, T1w/T2w ratio, magnetization transfer and myelin water fraction. Finally, we integrate imaging studies with cortical gene expression findings to further our understanding of the underlying neurobiology of the developmental changes, bridging the gap between ex vivo histological- and in vivo MRI studies.
