New data about geomorphological structure and neotectonic movements of the Lena Delta is presented. Thet are based on results of the Russian-German expeditions Lena-2013, Lena-2014, Lena-2015 and Lena-2018 and include geomorphological profiling with high quality satellite instruments and a number of radiocarbon dates on the Sobo-Sise, Kurungnakh, Jangylakh-Sis and Khardang-Sise islands. These islands consist of the Late Pleistocene Ice Complex (IC) remnants eroded by river and sea, and the first terrace of the Delta, which adjoins the remnants. The first terrace started to form 8,000 years ago in the western part of the Delta and was finally formed in the last millennium in the eastern part of the Delta. From the previous works, it is known that the western part of the Delta is higher than the eastern part. In our work, we explain it by the eneven movements of the Earth’s crust in this region. The aim of the paper is to study the quantitative characteristics of the tectonic movements in the Lena River Delta. For this purpose we present the geomorphological schemes and descriptions of the islands mentioned and compare the terraces heights in the different parts of the Delta. In the Late Pleistocene, according to the heights of the IC remnants, the western part of the Delta rose 1 mm per year faster than its eastern part. In the Holocene the speed difference increased to approximately 2 mm per year, which is shown by the terrace surface’s altitude. The amplitude between the western and eastern parts of this surface is about 4 m. Finally, according to 60-years observation period of the water level in the Laptev Sea, the modern speed difference of the western and eastern parts movement in the Lena Delta is 2 mm per year. As a result, we can observe changes in the main flow direction in the Delta channels from the Olenekskaya branch at the beginning of Holocene to the Bykovskaya branch today.

Fundamental Equation of Triangles
Authors: as Jayaram
Published: July 2019

This paper establishes a fundamental equation a^n+b^n=c^n, applicable for any triangle, having a, b and c as the sides with ‘c’ being the longest side and n is a number varying from 1 to infinity. Here, a, b, c and n need not always be integers. It also arrives at a relation between largest angle C (opposite to the longest side ‘c’) and sides of the triangle with the equation given by cosC=(〖(1+r^2)-〖{(1+r^n)}〗^(2/n))/2r, where r= b/a. The paper graphically and mathematically illustrates the relation between the angle C and ‘n’, for different values of ‘n’ and ‘r’ both varying from 1 to infinity. The paper also shows that Pythagoras theorem is a particular case of the above fundamental equation, when n=2. The paper shows that the above fundamental equation is valid even when a, b and c are integers for non-integer values of n>2. This gives a new way of looking at Fermat’s Last Theorem.

Interindividual Age Differences in Personality Structure
Authors: Beck Emorie D , Condon David M , Jackson Joshua James
Published: July 2019

Most investigations in the structure of personality traits do not adequately address age; instead they presuppose a constant structure across the lifespan. Further, few studies look at the structure of personality traits a-theoretically, often neglecting to examine the relationship among indicators within a trait (coherence) and across traits (differentiation). Using a network approach, the present study examines (1) age differences in differentiation and coherence, (2) the similarity between the Big Five and network structures, and (3) the consistency of network structure across age groups in a large, cross-sectional sample. Results indicate that coherence shows early gains in adolescence with few changes across the lifespan, while differentiation mostly weakens across adulthood. The result of these age-related changes is that Big Five indicators only parallel the Big Five structure among young but not older adults. The structure of young adults tends to be quite similar while the network structures of older adults appear to greatly differ from one another. These results suggest that older adults have a different structure of personality than younger adults and suggest that future research should not assume consistency in personality structure across the lifespan.
Displaying spatial epistemologies on web GIS: using visual materials from the Chinese local gazetteers as an example
Authors: Lin Nung-yao , Chen Shih-Pei , Wang Sean H. , Yeh Calvin
Published: July 2019

In this paper, we introduce a web GIS platform created expressly for exploring and researching a set of 63,467 historical maps and illustrations extracted from 4,000 titles of Chinese local gazetteers. We layer these images with a published, geo-referenced collection of Land Survey Maps of China (1903–1948), which includes the earliest large-scale maps of major cities and regions in China that are produced with modern cartographic techniques. By bringing together historical illustrations depicting spatial configurations of localities and the earliest modern cartographic maps, researchers of Chinese history can study the different spatial epistemologies represented in both collections. We report our workflow for creating this web GIS platform, starting from identifying and extracting visual materials from local gazetteers, tagging them with keywords and categories to facilitate content search, to georeferencing them based on their source locations. We also experimented with neural networks to train a tagger with positive results. Finally, we display them in the web GIS platform with two modes, Images in Map (IIM) and Maps in Map (MIM), and with content- and location-based filtering. These features together enable researchers easy and quick exploration and comparison of these two large sets of geospatial and visual materials of China.

An Organization, a Family, and Fifty Years of Homecomings: A Historical Reflection of American Peanut Research and Education Society
Authors: Beasley K.L.
Published: July 2019

From its early days when the Peanut Improvement Working Group (PIWG) became the American Peanut Research and Education Association (APREA), and later, the American Peanut Research and Education Society (APRES), this organization has evolved into a vital foundation within the peanut industry. For the past fifty years, the APRES meeting has become a juncture that brings together a diverse group of individuals from industry, academia, research, and business, to name a few, creating a space where the latest research, ideas, and concepts are produced, discussed, and shared. Most importantly, APRES is also about family. It is like having a yearly family reunion. This family-centric orientation makes the society and its yearly meeting very different from other organizations. Each year means seeing old friends, as well as watching children and grandchildren grow up, and strengthening that bond of being part of the APRES family through this connection. The evolution of APRES and the subsequent generations of new graduate students, scientists, researchers, and others continues to shape the direction of the society. APRES facilitates this connection between science, industry and friendship in an environment that mentors and cultivates the next generation of scientists and individuals in peanut production. By tracing the history of APRES, the role of the society emerges as a reflection of how the peanut industry is evolving, and with it, how the function and role of APRES evolves alongside it. For fifty years, this society and its yearly meeting continues to develop its place as a cornerstone of the peanut industry, as well as create a family atmosphere among its membership.
THE RESEARCH OF PETROLEUM JET PUMP OUTLOOK
Authors: Panevnyk O. V.
Published: July 2019

The development trends of hydraulic jet pumps used for the oil-fields exploitation are analyzed. The ambitionto optimize the process of mixing flows has led to the emergence of numerous designs of jet pumps, in which swirling flows are used instead of direct flows. The creation of circulation flows in the pump wet end promotes alignment of coaxial flows velocities, intensifies the process of energies exchange in the liquid, and increases the efficiency of the mixing process. The combination of direct and circulation flows gives a possibility to improve the technical characteristics of jet pumps up to 30%. The dimensions and the mutual orientation of the elements of the pump wet end have a decisive influence on the energy efficiency of the ejection technologies implementation. The optimization of dimensions and orientation of the components of the jet pump necessitates multifactorial experimental studies, which, in addition to the design factors, should also take into account the working mode of the ejection system in the well. The task of optimizing the design and mode parameters of a well ejection system can be solved by simulating the work process of the jet pump using modern software complexes Solid Works and ANSYS, which provide the necessary accuracy of the calculation operations. The efficiency of the ejection system also depends on the depth of its location in the well. Determining the optimum depth of installation of the ejection system in the well presupposes the use of iterative calculation methods with the aid of appropriate computer programmes (for example, Matchad). The development of the hydro-jet operation of oil wells is characterized by the tendency of a joint arrangement of the ejection system and traditional types of downhole pumping equipment. In the design of the combined oil-producing system the jet pump creates a low pressure zone in the bottom and intensifies the inflow ofhydrocarbons from the production horizon, while the traditional downhole pump transports them to the surface. The presence of an additional (jet) pump in the well optimizes the conditions of the main pump use. It improves the energy characteristics of the bottom-hole assembly and increases the efficiency of oil production. The analysis of the hybrid ejection technologies application indicates the prospects of this trend of oil and gas equipment.
MEIOS ADEQUADOS DE SOLUÇÃO DE CONFLITOS TRABALHISTAS E A PREVALÊNCIA DA VONTADE DOS SUJEITOS DA RELAÇÃO DE EMPREGO: COMPREENDENDO A DICOTOMIA ENTRE INDISPONIBILIDADE ABSOLUTA E INDISPONIBILIDADE RELATIVA DE DIREITOS TRABALHISTAS
Authors: Teixeira Sergio Torres , Cabral Delmiro Borges
Published: July 2019

Com as recentes alterações promovidas na legislação trabalhista pela Lei 13.467 de 2017 (Reforma Trabalhista), o legislador procurou incentivar o uso de outros meios de solução de conflitos fora do processo judicial contencioso da Justiça do Trabalho, como a arbitragem privada e a negociação extrajudicial direta entre empregado e empregador. O estímulo à ideia de um modelo multiportas de acesso à justiça, entretanto, tem enfrentando uma certa resistência por parte de magistrados e advogados já ambientados no sistema adversarial de embate beligerante entre os litigantes. E dentre as dificuldades levantadas pelos refratores, se encontra o dogma da indisponibilidade dos direitos trabalhistas, por meio do qual se nega a possibilidade do empregado de se despojar de um direito trabalhista assegurado em uma norma de ordem pública, considerando que o trabalhador é a parte hipossuficiente na relação empregatícia e como tal o destinatário de uma tutela jurídica especial. O presente texto almeja proceder a uma análise crítica de tal dogma, mediante uma incursão no ambiente da dicotomia envolvendo a indisponibilidade absoluta e a indisponibilidade relativa de direitos trabalhistas, examinando como a conscientização acerca de tal bifurcação pode contribuir para viabilizar a proposta legislativa, assegurando a prevalência da vontade das partes sem ferir as normas que norteiam o ordenamento jurídico trabalhista pátrio. Utilizando o método dedutivo por meio de uma pesquisa qualitativa da literatura especializada, o objetivo será conduzir um exame técnico dos novos instrumentos introduzidos pelo legislador de 2017 à luz de uma visão sem preconceitos acerca da autonomia da vontade das partes dentro dos filtros tipificados de um modelo normativo trabalhista brasileiro que se encontra em evidente evolução.

Published: July 2019

Cancer registration is an organization for the systematic collection, storage, analysis, interpretation and reporting of data on subjects with cancer. Cancer Registry was initiated in 1995 and expanded as National Cancer Registry Program since 2003 by BP Koirala Memorial Cancer Hospital with the support of World Health Organization. NCRP currently includes 12 hospital-based registries. First time in Nepal, BPKMCH piloted population-based cancer registry in 2013, which included 15 districts covering 25.8% of total population of Nepal. NCRP is important to assure the quality of data from all the registries to ensure the availability of reliable and valid data of cancer cases. This will further help policymakers to develop prevention and control strategies of cancer. This paper reviews the current status of cancer registries in Nepal and discusses challenges and future prospective related to NCRP. National cancer registry should further include major hospitals in Nepal to give scientific information on cancer trends by community, provinces and regions and analyze on survival of cancer cases.

Methods: It was descriptive cross-sectional study conducted from November 2017 till June 2018.Ethical approval was taken from Ethical Review Board, Nepal Health Research Council. Informedand written consent was taken. Patients undergoing hemodialysis at Nepal Medical College for >3 months duration were included in study. Patients on hemodialysis were asked to fill validatedNepali translated version of Patient Health Questionnaire -9. Psychiatrist administered MaxHamilton Rating scale for diagnosis and categorization of depression and confirmed depressionbased on International Classification of Disease -10. Statistical Package for Social Sciences version 20was used for statistical analysis.

Results: Total of 100 patients completed study. Median age was 47.5 years. Prevalence of depressionwas 78 (78%) using Patient Health Questionnaire-9 and 65 (65%) using Max Hamilton Rating scaleand 51 (51%) using International Classification of Disease -10. Mean depression in males using PatientHealth Questionnaire -9 was 7±4.33 and in females was 11.04±5.90. The most common symptom wasfatigue among 82 (82%).

Conclusions: There is a high prevalence of depression in patients with Chronic Kidney Disease onhemodialysis compared to general population.

Published: July 2019

Introduction: Poor dental hygiene has been associated with various perinatal complications in studiesdone worldwide but few studies in Nepal have explored the knowledge of pregnant ladies regardingdental hygiene. The aim of the study was to know the knowledge and practices of pregnant womenregarding oral health in a tertiary care center in Nepal.

Methods: A qualitative study was carried out in Nobel Medical College and Teaching Hospital fromJanuary 15, 2018 to June 15, 2018 after approval from the Institutional Review Committee of NobelMedical College. Convenience sampling was done. Fifty pregnant women admitted in antenatalward were interviewed regarding their knowledge of dental care in pregnancy, the common dentalproblems they faced and the treatment taken. A predesigned proforma was used and results wereanalyzed using SPSS version 17.

Results: Twenty two (44%) patients reported dental problems during pregnancy. Bleeding gumswas seen in 7 (14%) and toothache in 7 (14%) were commonly reported dental problems. Forty seven(94%) patients acknowledged that routine dental care was needed for health, only 6 (12%) wereaware that poor dental health could affect baby weight. Oral health not seen as priority in 24 (48%)was the main barrier to seeking dental care in pregnancy followed by costs of treatment in 18 (36%)and safety concerns in pregnancy in 8 (16%) cases.

Conclusions: Though dental problems were a common occurrence in pregnancy, utilization ofservices was low for the same. The participants reported significant barriers to obtaining dental careincluding lack of knowledge about the importance of maternal oral health and the treatment costs.

Published: July 2019

Introduction: Perinatal mortality indicates quality of maternal and neonatal care and is high inNepal. This study was conducted to find out the prevalence of perinatal deaths in a tertiary carecenter.

Methods: This descriptive cross-sectional study was conducted from July 2017 to June 2018 at KISTMedical College and Teaching Hospital. Details of each perinatal death were filled in predesignedproforma from hospital in-patient records within 24 hours of perinatal death. The total of 1088 caseswere selected for the study and convenience sampling was done. Statistical analysis was done withStatistical Package for Social Sciences (SPSS 17.0).

Results: Out of 1088 births selected for the study, there were 16 cases of perinatal deaths. Hence,the prevalence of the perinatal deaths in KIST Medical College and Teaching Hospital is found to be1.47%. In the same way, perinatal mortality rate, stillbirth rate and early neonatal mortality rate werecalculated and found to be 14.61 per 1000 births, 8.21 per 1000 births and 6.44 per 1000 live birthsrespectively. Preterm neonates constituted of 71.4% of early neonatal deaths.

Conclusions: Perinatal mortality rate was 50% lower than that of national survey, however comparablewith study at another tertiary care center at Kathmandu. Stillbirth and prematurity contributedsignificantly to perinatal mortality. Provision of good antenatal surveillance, identification of highrisk pregnancies and good neonatal care to preterm neonates would be required to reduce perinatalmortality.

Authors: Shah Prishita , Manandhar Rosina , Thapa Meena , Saha Rachana
Published: July 2019

Cesarean scar pregnancy is a rare variant of ectopic pregnancy where the fertilized ovum gets implanted in the myometrium of the previous cesarean scar. The incidence of CSP among ectopic pregnancies is 6.1% and it is seen in approximately 1 in 2000 normal pregnancies.As trophoblastic invasion of the myometrium can result in uterine rupture and catastrophic hemorrhage termination of pregnancy is the treatment of choice if diagnosed in the first trimester. Expectant treatment has a poor prognosis and may lead to uterine rupture which may require hysterectomy and subsequent loss of fertility. We present a case report of a 24year old femaleG2P1L1with ruptured cesarean scar pregnancy who underwent emergency laparotomy and subsequently hysterectomy. In this case report, we aim to discuss ruptured cesarean scar pregnancy as obstetric emergency and methods by which we can make an early diagnosis that can be managed appropriately as to prevent maternal morbidity and mortality.

Published: July 2019

Microphthalmos results from incomplete invagination of the optic vesicle or closure of theembryonic fissure. We present three patients with unilateral congenital microphthalmia withcyst. None of them had vision in the affected eye since birth, with gradually increasingmass encroaching towards lower fornix and lower eyelid ectropion. On examination andinvestigations, patients had large orbital cyst with microphthalmia pushing the eyeball superiorlyand posteriorly in affected orbit. Microphthalmic globe with cyst was surgically excised andhistopathologically studied. Orbital cavity was big enough to occupy the conformer and theprosthetic eye after 6 weeks. Diagnosis was confirmed by large communicating orbital cyst withmicrophthalmia without systemic association in all the patients. None of the mothers of patientshad (antenatal care) ANC check up. All the parents had consanguineous marriage. ANC checkup with ultrasound at 14-16 weeks of pregnancy is important for genetic counselling.
Pore space of carbonate tidalites — paleoclimatic aspect
Authors: Kuznetsov V. G. , Zhuravleva L. M.
Published: July 2019

Carbonate deposits of tidal zones are characterized by micritic structures, considerable content of clay material, wide development of cyanobacterial formations. Under arid climate conditions, dolomite tidalites are formed in association with evaporites, which contain numerous interlayers of stromatolites. Dolomitic tidalites make up the lower and upper elements of three-membered transgressive-regressive cyclites, and talidites deposited in a humid climate lie at the base of two-membered cyclites composed of limestone. The pore space is very specific in both cases, due to the wide development of bacterial formations, and this determines the sharp permeability anisotropy.

Published: July 2019

The data are given on the structure, chemical composition, and content of microelements in the ferromanganese and siliceous crusts of Pervenets Rise (the Sea of Japan). The crusts resulted from the cementation of small fragments of green clays (celadonite) with hydroxides of manganese (todorokite and birnessite) or silica. Initial was the formation of celadonite deposited during the eruption of ore-bearing hydrothermal solutions in the volcano caldera or on its slopes.The features of the crust structure show that they were originated through the diffusive infiltration of gas-hydrothermal solutions along the fractures or weakened zones in volcanic rocks and subsequent cementation of the celadonite already formed occurrences with manganese or siliceous oxides. The manganese and siliceous mineralization is separated in time and often in space and demonstrate more local distribution.
Volcanism and geochemistry of soil and vegetation cover of Kamchatka. Communication 3. Elemental composition of vegetation of volcanic ecosystems
Authors: Zakharikhina L. V. , Litvinenko Yu. S.
Published: July 2019

The link of the chemical composition of the plant with the active volcanism of Kamchatka, is determined by the stable occurrence into the composition of the priority chemical elements for plants, volcanic ashes and soils: Ca, Mg, Mn, P, Cu, Zn and Sr. An elevated geochemical background of Kamchatka plants relative to the bulk chemical composition of the peninsula’s soils was established. The contents of Br, Hg, Hf, Sb, Ga, W, K relative to the clarks for living matter in the plants of the region are exceeded by 3–5 times. Against the background of small variations in the contents of chemical elements in plants of different regions, the relatively rich biogeochemical background of the Western region of the southern province (the western coast of Kamchatka) is determined, where most ancient near-surface volcanic ashes for Kamchatka are transformed into humus-accumulative horizons. On the territory of young volcanic ash fallout in the immediate vicinity of volcanoes, the relative richness of vegetation with chemical elements and the poverty of soils by mobile forms of elements have been established. On the contrary, at a distance from the volcanoes in the zone of far transfer fallout ashes, there is a marked relative poverty of plants and soil richness of available chemical elements.
The labor potential of Russia: demographic and socioeconomic problems of formation and usage
Authors: Topilin A. V.
Published: July 2019

The article clarifies the term "labor potential", considering modern scientific approaches. The peculiarities of the formation of labor potential are reflected in the conditions of the second wave of depopulation. The main directions of employment expansion due to the increase of labor activity of social and demographic population groups are considered. These groups include youth, invalids, and pensioners. The specificity of structural shifts in employment in comparison with developed Western countries is revealed. The role of re-emigration and external and internal labor migration in achieving a balance of demand and supply of labor is noted. Proposals on the main directions of the strategy of development and usage of labor potential are also given.

Published: July 2019

Über die personal- und arbeitspolitischen Besonderheiten in den Unternehmen der Erneuerbaren Energiewirtschaft ist vergleichsweise wenig bekannt. Dabei bieten insbesondere diese neu entstehenden bzw. entstandenen Branchen eine hervorragende Möglichkeit, die Verankerung in arbeitspolitischen Institutionen im Allgemeinen und im deutschen Kontext kollektiver Arbeitsbeziehungen im Besonderen zu erkunden. Der vorliegende Beitrag zielt daher auf die Beantwortung der Frage, ob und auf welche Weise im Zuge einer sich herausbildenden Personalpolitik auch eine arbeitspolitische Verankerung erfolgt und inwieweit inner- und überbetriebliche Kontextbedingungen auf diese Entwicklung einwirken.
Die Motivation von Arbeitnehmervertreterinnen und -vertretern zur Übernahme eines Aufsichtsratsmandats: Ein qualitativer Ansatz
Authors: Walther Axel , Möltner Hannah , Morner Michèle
Published: July 2019

Der Beitrag untersucht auf Basis der Selbstbestimmungstheorie, wie Einflussgrößen des sozialen Kontexts Arbeitnehmervertreter und Arbeitnehmervertreterinnen zur Übernahme eines Aufsichtsratsmandats motivieren. Die Analyse von 29 teilstrukturierten Interviews zeigt ein breites Motivationsspektrum bei Arbeitnehmervertreterinnen und -vertretern in deutschen Aufsichtsräten börsennotierter Unternehmen. Wir zeigen, dass sich je nach Ausprägung einzelner Motivationsfaktoren drei unterschiedliche Motivationsprofile ergeben, die wir in ein „identifiziert/intrinsisches“, ein „ausgeglichenes“ und ein „introjiziert/externes“ Profil unterteilen. Mittels unserer qualitativen Analyse kristallisieren sich die Unterstützung durch persönliche Netzwerke und die Heranführung an ein Mandat als zwei wichtige Einflussgrößen des sozialen Kontexts heraus, wie Arbeitnehmervertreterinnen und -vertreter zur Übernahme eines Aufsichtsratsmandats motiviert werden können.
