Published: June 2020

This article is dedicated to examination of the history of emergence of Greek mercenaries during the riling time of XXVI Sais Dynasty. The author reviews the status and role of Greek mercenaries in the armed forced of Sais rulers, organization of their service and living conditions. Considering the fact that the use of Greek mercenaries in Egypt army was a part of the traditional policy of Sais rulers and carried mass character, the author refers to the problem  of social origin of the phenomenon of mercenarism in the Greek society of Archaic era. The research applies comparative-historical method that allows viewing the phenomenon of mercenarism in the historical context – based on the comparative data analysis of ancient written tradition. By the time of Sais Dynasty, control over regions that traditionally provided mercenaries to the Egypt army was lost. Under the circumstances, in order to compensate such losses, Egypt conscripted into military service the hailed from the Greek world. Mercenaries became the first Greeks settled on the Egyptian land. The conclusion is made that the Greek colonization, in absence of other ways to enter the formerly closed to the Greeks Egypt, at its initial stage manifested in such distinct form.

The peculiarities of marriage leadership and psychological climate in a family
Authors: Iakimanskaia Irina
Published: June 2020

Psychological microclimate of a family is an important factor determining health, social and work activity of family members and society overall. The following traits are characteristic for a favorable psychological climate – team spirit, opportunity for personal growth for each spouse, kindness to each other, feeling of security and emotional satisfaction, pride for being a part of their family, responsibility. The basis for favorable climate of a family is marital relations, namely such manifestations as leadership and domination. In accordance with this, the research divided the families into three groups: with traditional leadership (patriarchy), nontraditional leadership (matriarchy), and egalitarian leadership (equal partnership); and then compared the psychological climate and wellbeing of family members. Based on the acquired results, the article states that in family relations women demonstrate higher level of frustration than men do. Women desire emotional closeness, aspire to achieve understanding, experiencing anxiety, tension and guilt. The highest level of anxiety and tension is noticed in couples with patriarchy. The article suggests that subordination leads to decrease of self-confidence of women, fear to end up alone and lose support of their husbands. Inclination to the feeling of guilt manifests among women who demonstrate leadership in family relations, as well as among those who desire to avoid it.

Authors: Riora Haswinta
Published: June 2020

Reading poetry is one of the skills in the field of literature included in the learning of Indonesian language and literature in high school. Reading poetry is not the same as reading in general. Reading poetry requires a special skill, namely a reading expression skill. Reading expression trains students to be creative in expressing a poetic text and creating appreciation, vocal techniques, and appearance that are following the contents of the poetry. Unfortunately, based on the field observation, it found that the poetry reading skills of students in class XII Social Science 1 at SMAN 16 Pekanbaru were still low, as seen from the lack of students’ ability in ensouling, vocal techniques, and performances that did not match the contents of the poetry they read. The problem formulation of this study was whether the use of basic outdoor training techniques can improve students' poetry reading skills and how the changes of students’ behaviors in reading poetry learning after applying basic outdoor training techniques in class XII Social Science 1 at SMAN 16 Pekanbaru? This study aimed to describe the improvement of students' ability in reading poetry and to investigate the changes of students’ behaviors in reading poetry learning after applying basic outdoor training techniques in class XII Social Science 1 at SMAN 16 Pekanbaru. The type of this research was classroom action research. The results of this study show that there was an improvement of students' poetry reading skills with an average score of the cycle I was 69.32 and an average score of the cycle II was 82.97. In other words, there is an increase from cycle I to cycle II of 13.65 points or 19.69%.

Published: June 2020

Enantiodivergence is an important concept in asymmetric catalysis that enables access to both enantiomers of a product relying on the same chiral source. This strategy is particularly appealing as an alternate approach when only one enantiomer of the required chiral ligand is readily accessible but both enantiomers of the product are desired. Despite their potential significance, general catalytic methods to induce reversal in enantioselectivity remain underdeveloped. Herein we report our studies focused on elucidating the origin of enantioselectivity reversal in Lewis acid-catalyzed Michael additions relying on the same enantiomer of ligand as the chiral source. Our results provide a detailed mechanistic understanding of this transformation based on experimental and computational investigations which reveal the important interplay between kinetics and thermodynamics responsible for the observed enantiodivergence.
Chemical Compositions in Salinity Waterflooding of Carbonate Reservoirs: Theory
Authors: Yutkin Maxim , Radke Clayton J. , Patzek Tadeusz
Published: June 2020

Higher oil recovery after waterflood in carbonate reservoirs is attributed to increasing water wettability of the rock that in turn relies on complicated surface chemistry. However, calcite mineral reacts with

aqueous solutions, and can alter substantially the composition of injected water by mineral dissolution. Care-

fully designed chemical and/or brine flood compositions in the laboratory may not remain intact while the

injected solutions pass through the reactive reservoir rock. This is especially true for a low-salinity waterflood

process, where some finely-tuned brine compositions can improve flood performances, whereas others cannot.

We present a 1D reactive transport numerical model that captures the changes in injected compositions dur-

ing water flow through porous carbonate rock. We include highly coupled bulk aqueous and surface carbonate-

reaction chemistry, detailed reaction and mass transfer kinetics, 2:1 calcium ion exchange, and axial dispersion.

At typical calcite reaction rates, local equilibrium is established immediately upon injection. Using an open-

source algorithm (Charlton and Parkhurst 2011), we present a design tool to specify chemical/brine flooding

packages that correct for composition alteration by carbonate rock.

Here, we present a comprehensive 1D reactive transport model and validate it against analytic solutions

for rock dissolution, ion exchange, and longitudinal dispersion, each considered separately. A companion paper

compares the proposed theory against experiments on core plugs of Indiana limestone that serve as high velocity

probes for reaction-controlled and mass-transfer-controlled dissolution. Finally, in another companion paper,

we give examples of how injected salinity compositions deviate from those designed in the laboratory for water-

wettability improvement based on contact angles, zeta potentials, surface charge densities, and ion exchange.

How to correct the design chemical packages for exposure to reactive rock is also discussed in there.

Diabetes mellitus ‘the disease of modern civilization’ is characterized by chronic hyperglycaemia. The management of elevated post prandial glucose is critical to control the sequale of complications and α-amylase, α-glucosidases are responsible for elevated plasma glucose. Enzyme inhibitors in current clinical practice like acarbose, voglibose etc. are known to cause various gastrointestinal side effects. The present study was aimed to screen for potential α-amylase and α-glucosidase inhibitors from natural sources by in–vitro antidiabetic assays to overcome the side effects and toxicity. Different concentrations of leaf juice of Plectranthus amboinicus Lour. (20, 40, 60, 80 &100 μg/ml) were tested against fungal α-amylase and α-glucosidases isolated from albino rat small intestine and a prominent dose dependent inhibition of the enzymes was observed comparable with the marketed product, Acarbose. The IC50 values of LJPA and acarbose on fungal α-amylase was found to be 83.15 &52.15 μg/ml respectively. The IC50 values of LJPA and acarbose on α-glucosidase was found to be 92.44 &54.84 μg/ml respectively. The protein concentration of leaf juice was found to be 10.6 mg/ml.
Identification of the mutated sites present in the transmembrane regions of SCN1A_HUMAN (Sodium Voltage-Gated Channel Alpha Subunit 1) using Insilico techniques
Authors: Balaji Munivelan
Published: June 2020

Mutations in numerous genes which encode for voltage-gated sodium channels give rise to various epilepsy syndromes in humans. Our research investigation mainly focuses on the identification of the integral membrane protein of the SCN1A (Sodium Voltage-Gated Channel Alpha Subunit 1) in humans. Secondary, we focus on the transmembrane membrane (TP) amino acids directly involved in the epilepsy-involved mutated regions. Using Insilico protocols, we identify the TP proteins and amino acids and elucidate the Transmembrane Helix and the inside and outside amino acids regions of the SCN1A. With the help of Insilico proteomics server, the amino acids in the mutated regions involved in the TP were identified. Finally, 3D structure prediction was performed using homology modelling server and the modelled structure was cross validated for the TP and validated. The identified results were validated using molecular visualization tools. We prove that the mutated amino acids are present in the outer membrane of the TP regions. Thus, the outer membrane of sodium channel and the amino acids present in the outer membrane (T875M, R859C, and R1648H) play a vital role in Structure-Based Drug Designing and Drug Docking studies.

Published: June 2020

Silver nanoparticles have their demand in various fields of science and technology and their applications extend even in medical and pharmaceutical arenas. They have been used as preservatives, diagnosing aids and potent antibacterial agents. But their production is a serious matter of concern when it comes to cost, efficacy and toxicity issues. Overcoming these limitations green synthesis has taken its advantage for their commercial and large scale synthesis. This research concentrates on the preparation of silver nano particles by using purified leaf extract of Lannea coromandelica and evaluation of the same using UV-Vis Spectrophotometry, FTIR, EDXS, SEM and particle size analysis. The produced nanoparticles exhibited surface plasmon resonance at 420nm in UV spectroscopy. EDS Spectrum showed the presence of metallic silver in the solution. They are roughly cubic in shape, smooth surfaced and measure about 10-20nm in diameter which is evident from the particle size analysis. FTIR studies revealed the presence of O-H groups indicating polyphenols and also confirms capping of proteins over the nanoparticles. The results proved the eco-friendly synthesized silver nanoparticles. The prepared nanoparticles have been analyzed using sophisticated analytical instruments. The results confirm the formation of silver nanoparticles. The bio-mimetic synthesis of silver nanoparticles is relatively safer and cost effective. The potency and effect of silver nanoparticles was determined yet the toxicity was to be considered for establishing it as a therapeutic agent.

Published: June 2020

The demand for mixed joints of hard-welded steels used in civil engineering and transport is increasing. An example of this can be welding of pins of high-strength steel S690 QL (1.8928) with the arms of a movable platform made of DOCOL 1200M steel from the AHSS group. This joint is difficult to make properly, due to significant differences in the thickness of welded elements and different chemical composition of both steels. The thickness of the cylindrical pin is 40 mm, the diameter of the pin is 50 mm. The thickness of the metal sheet used for the mobile platform arm is 2 mm. . Joints of varying thickness and chemical composition may have cracks in the heat affected zone and in the weld. The purpose of the article is to determine the most appropriate welding parameters and the selection of filler materials that will allow to obtain the correct joint without welding defects.

Published: June 2020

With the development of microprocessors, actuators and structural micro-components, new concepts of micro-electro-mechanical systems/machines are constantly being introduced. One of the consequences of this tendency is seeking for best techniques to connect metal micro-components. Because of tools simplicity, no additional fastening parts and the undisturbed structure of the material, clinching appears to be a promising method for joining in micro-scale. A procedure for the analysis of micro-clinching process is proposed in the paper, and unique, support flexible tooling system designed. This system allows to easily change key parameters of the process. With the use of flexible micro-tooling, a successful micro-clinching of silver sheets of thickness 0.18 mm has been conducted. An effective numerical method - Rapid Numerical Strength Test - for modelling the process of tearing the joints has been presented. Compliance of key phenomena recognized in modelling with experimental results was obtained.
A beginner’s guide to molecular identification of seaweed
Authors: Zuccarello Giuseppe , Paul NA
Published: June 2020

© 2019, Squalen BMFPB. The most rapidly expanding areas for seaweed production in the world are the tropics, including Indonesia, yet these areas are also where molecular identification of local marine flora has only been sporadically employed. Furthermore, a goal for the Government of Indonesia is to diversify the types of seaweed that are being utilized, targeting valuable products and, hand in hand, to develop aquaculture techniques for these species. Morphological methods for species identification in algae are complex or unreliable, due to simple morphologies and plasticity. Therefore, it is crucial that the correct identification is made for species and varieties of commercial interest so that growth and biochemical results can be compared and contrasted between locations, across environments and over time without taxonomic ambiguity. This guide presents entry level methodologies for sample collection, DNA preservation, DNA extraction, PCR, and analyses of DNA sequence data, as a first step in the genetic characterization of both well-known cultivated species and identification of different species with potential economic properties.
Effect of activity states on habitat selection by black-tailed deer
Authors: Bose S , Forrester TD , Casady DS , Wittmer Heiko
Published: June 2020

© The Wildlife Society, 2018 Habitat selection is a complex hierarchical process and in ungulates typically varies at broad spatial and temporal scales and among individuals. Recent advancements in the ability of global positioning system (GPS)-collars to collect activity data provide opportunities to understand underlying mechanisms or trade-offs responsible for fine-scale variation in habitat selection. Based on data from 64 female black-tailed deer (Odocoileus hemionus columbianus) fitted with GPS-collars in northern California, USA, between 2004 and 2013, we first investigated habitat selection at the home range scale. We then used data from a subset of 27 individuals to determine if habitat selection within home ranges was influenced by activity states (active or inactive). Habitat selection by black-tailed deer varied between summer and winter and was mostly explained by differences in elevation, terrain, and vegetation. Within their home ranges, black-tailed deer showed fine-scale selection for habitats that varied with activity states. In summer, selection for edge density and forest types varied across activity states highlighting important fine-scale selection patterns. Activity state also affected our conclusions about the selection of habitats including slope, canopy cover, and forest types by black-tailed deer in winter. During both seasons, deer selected for apparently secure habitat when inactive, likely to minimize risk of predation. These results highlight the importance of considering activity states when evaluating habitat selection from animal location data. This is particularly important in multi-use landscapes such as national forests where habitat needs of ungulates are important considerations in management decisions, including timber harvest. © 2018 The Wildlife Society.
Predator occurrence and perceived predation risk determine grouping behavior in guanaco (Lama guanicoe)
Authors: Iranzo EC , Wittmer Heiko , Traba J , Acebes P , Mata C , Malo JE
Published: June 2020

© 2018 Blackwell Verlag GmbH Grouping behavior of social ungulates may depend on both predator occurrence and perceived predation risk associated with habitat structure, reproductive state, and density of conspecifics. Over 3 years, we studied grouping behavior of guanaco (Lama guanicoe) families in Chilean Patagonia during the birthing season and determined their response to variation in predator occurrence and perceived predation risk (habitat structure, calf/adult rate, and density of conspecifics). We considered the effect of two predators, puma (Puma concolor) and culpeo fox (Lycalopex culpaeus). We measured two common (family group size and vigilance) and one novel (family group cohesion) behavioral responses of guanaco. Our results show that guanaco family groups adapted their grouping behavior to both predator occurrence and perceived predation risk. Larger family groups were found in open habitats and areas with high puma occurrence, while guanacos stayed in small family groups in areas with high shrub cover or low visibility. Group cohesion increased in areas with higher occurrence of pumas and culpeo foxes, and also increased in smaller family groups and in areas with low guanaco density. Vigilance (number of vigilant adults) was mainly related to group size and visibility, increasing in areas with low visibility, while residual vigilance (vigilance after removing the group-size effect) did not vary with the explanatory variables examined. Our results suggest that a mix of predator occurrence and perceived predation risk influences guanaco grouping behavior and highlights the importance of evaluating different antipredator responses together and considering all predator species in studies aimed at understanding ungulate behavior.

Covid-19 revolutionising higher education: An educator’s viewpoint of the challenges, benefits and the way forward
Authors: Cheema Manraj Singh
Published: June 2020

The global COVID-19 pandemic has radically change the higher education landscape that caused closures of all education institutions in adherence to social distancing. It has forced the education sector to adopt online teaching and learning, and reminded educators that a flexible and robust education system is needed as the future is unpredictable. This paper focuses on educator’s viewpoint in adapting and adopting online teaching and learning, highlights the challenges experienced and the ways to overcome it that could serve as a reference for other educators to assimilate in similar circumstances. This paper also explores and discusses the benefit brought by these changes to higher education and the way forward in progressing, revolutionising and sustaining quality online teaching and learning where globalised, borderless and seamless teaching and learning with technology may become “the new normal” in higher education.
Orbita medial duvarındaki kemik dehissansların bilgisayarlı tomografi ile görüntülenmesi ve literatürdeki terminolojik hataların değerlendirilmesi

Orbita medial duvarını oluşturan kemik yapılar lakrimal kemiğin lateral ya da orbital yüzü, maksiller kemiğin frontal prosesi, ethmoid kemiğin lamina papyracea’sı ve sfenoid kemiğin korpusudur. Paranazal sinüsler (PNS) çok fazla varyasyonun görüldüğü bir bölgedir. Kemik yapılar çok ince olup dehisanslar sık görülür [ONODİ 1909].

Bu çalışmamızda standart PNS BT incelemesi yapılan hastalarda kemik devamlılığın bozulduğu vakaların sıklığını,  yaş ve cinsiyet ilişkisini araştırmayı, orbita medial duvarındaki kemik defektlerin saptanması konusunda Bilgisayarlı Tomografi etkinliğinin ortaya konulmasını, ayrıca geniş bir literatür taraması ile bu malformasyon konusunda yapılan paylaşımlardaki terminolojik farklılıkların vurgulanmasını amaçladık. Paranazal sinüslere yönelik olarak uygun şartlarda çekilen Bilgisayarlı Tomografi (BT) sinonazal anatomi ve varyasyonları hakkında detaylı bilgiler verir.

Çekimler GE marka IQ model 32 dedektörlü spiral cihaz ile, 130 kV voltaj ve 80-120 mAs değerleri kullanılarak kemik protokolüne uygun olarak yapılmıştır. 115 hastaya (59 erkek, 56 kadın) ait 230 orbita medial duvar incelemesinde 71 adet (%30.9) kemik defekt saptandı (34 erkek, 37 kadın). Bu vakaların 8’inde (4 erkek, 4 kadın) (% 3.5) orbital yağ dokusunun etmoid sinüs içerisine herniasyonu mevcuttur.

Çalışmamızda herniasyon bulunmayan kemik devamlılık kaybı literatürde bahsedilenden fazla bulunmuştur. BT incelemelerinde belli kalınlığın altındaki düşük dansiteli kemik yapının dansite farklılığının ayırt edilememesinin bu sayıdaki büyüklüğün sebebi olabileceği ve bulguların BT çekilen kadavra spesimenlerinde dehisans saptanan  örneklere mikrodiseksiyon yapılarak teyit edilebileceği düşünülmüştür.

Sonuç olarak radyolojistlerin PNS CT değerlendirmesinde herniasyon olsa da olmasa da mutlaka bu dehisansların varlığını araştırmaları gerektiği, yapılan yorum ve çalışmalarda herniasyon ve dehisans / Gap kelimelerinin doğru kullanılmasına daha fazla özen gösterilmesi gerektiği kanaatindeyiz.

The farm is an important sector that affects economic growth. El-Nino and La-Nina climate anomalies have an impact on the farm such as drought. Actions to overcome the limiting factors on marginal land need to be done through technologies application on soil conservation and water management, balanced soil nutrient management and a better understanding of climate anomalies. Therefore, mitigation models development and anticipation of the effects of drought need to be carried out to provide an alternative technology. The research stages was biophysical conditions analysis, hydrological and geological data analysis, and formulation of drought mitigation technology. Based on the research, there is a drought potential that needs to be anticipated. Technology that could be applied are water reservoirs, dykes, infiltration canals, rorak, slot mulch, and reservoir.

In this study, fruit properties of 19 rose hip (Rosa spp.) genotypes selected from a large number of genotypes in the natural rose hip population in Akkuş district (Ordu province) in 2014-2015 were determined. The genotypes belonged to Rosa dumalis Bechst., Rosa gallica L. and Rosa canina species. They had a range of 1.22-3.47 g in fruit weight, 10.2-16.9 mm in fruit width, 13.2-25.2 mm in fruit length, 1.25-2.09 in fruit shape index, 62-72% in fruit flesh ratio, 16-35 in seed number, 13.6-24.4% in total soluble solids, 560-1025 mg 100g-1 in C vitamin content, and 1.06-2.48 Brix° in titratable acidity. The five genotypes were less thorny plants. The two genotypes (AK-75 and AK-20) were evaluated as promising in terms of fruit weight and fruit flesh ratio. In addition, AK-63 for TSS content and AK-16 for vitamin C content were found remarkable. Findings revealed that some genotypes could be valuable as genetic material for future breeding efforts.
