Authors: Alvarez Ma. Lourdes C. 
Published: August 2020

This study aimed to determine and describe the conceptual understanding in chemical equilibrium among selected freshman students who were classified as surface and deep learners. Data were gathered utilizing study process questionnaire and conceptual understanding test. This study involved two intact classes of 58 engineering students enrolled in General Chemistry II and was conducted for three weeks. Using the study process questionnaire, students were classified as either surface or deep learners. After the lesson on chemical equilibrium, conceptual understanding test was given to the students. Students were then grouped into six based on their learning approaches and level of conceptual understanding.
The findings of the study revealed that majority of the class (53%) are deep learners while 47% are surface learners. Using t-test analysis, surface and deep learners differ in the scores they obtained on concepts about factors affecting equilibrium. Chi square test of independence also showed that surface and deep learners significantly differ from each other in terms of their level of conceptual understanding on factors affecting equilibrium concepts.
The results of t-test and chi-square test revealed that there could be times that differences between surface and deep learners could only be seen when tested across different concepts within a certain topic.

Published: August 2020

The investigation purpose is life increase of clutch couplings in rotary pump units by means of designing an advanced clutch coupling.
For that there were defined the reasons of failure and short life of an elastic sleeve-pin clutch for joining a rotary pump and electromotor. As a result of industrial tests of a rotary pump unit there were revealed the following factors decreasing life and hence equipment reliability: a wrong alignment with the pump; half-coupling imbalance (pin wear, non-coaxiality (misalignment) of holes for pins or half-coupling misalignment); bearing unit gaps (bearing defects); pump and electromotor rotor balancing; mounts and abutments of a frame base.
For elimination of drawbacks revealed there was developed an updated design of an elastic sleeve-pin clutch for the rotary pump of 200D90 type having no counterparts in Russia. During the investigation there were carried out industrial tests at PC “Samotlorneftegas”. Due to the updated design offered the clutch ensures life increase and a more reliable working capacity in the course of operation.

Published: August 2020

The purpose of this work consists in ensuring the required quality of micro-geometry and mechanical characteristics of a surface layer in rolling mill parts, in particular, surface roughness no more than Ra=2.5mkm and micro-hardness no less than 900 kgs/mm2.
To ensure such micro-hardness in samples of 60HN steel there were applied coatings
With the method of electrospark alloying with the use as an electrode synthetic hard tool materials based on titanium diboride (STIM-11) and titanium carbide (STIM-40NA) made by the method of self-propagating high-temperature synthesis. EIL-coatings made of thses materials are characterized with the thickness of 30mkm, micro-hardness up to 980 kgs/mm2, that exceeds four times micro-hardness of a non-hardened sample, and with roughness Ra=5…10mkm.
To decrease roughness of EIL-coatings made of STIM materials for the first time there was used surface plastic deformation with smoothing that is a novelty of this investigation. Smoothing was carried out on a screw-cutting lathe with the aid of a flattener with TC6 tungsten-cobalt hard alloy indenter (r=6mm) at the rotational frequency n=70rev/min and at the indenter longitudinal feed S=0.05mm/rev and the smoothing force P=500N. As a result of smoothing the micro-hardness of surface layers made 990kgs/mm2, and roughness – Ra=1.6…1.8mkm.
Conclusion: smoothing contributes to the decrease of surface layer roughness from 3 times (STIM-40NA) to 5.5 times (STIM-11) at the conservation of their mechanical characteristics that proves the outlook in use of such a technology for finishing parts surfaces strengthened with SVS-electrode materials by STIM method of electrospark alloying.

Introduction. Performing flights on modern types of aircraft is accompanied by an increase in the role of process automation, changes in the structure of the pilot’s information field, an increase in the number of controlled indicators throughout the flight time and, as a result, an increase in sensory loads that contribute to the development of chronic depletion of functional reserves of the body and fatigue of the pilot, which can cause accidents and plane crashes.The aim of the study is to assess the sensory loads of members of flight crews of civil aviation aircraft when they perform regular operating procedures in a Training center on fully functional complex simulators for training cadets, flight, dispatcher and technical personnel of civil aviation.Materials and methods. A hygienic study was conducted to assess the sensory loads of pilots in the framework of performing simulation flights on full-featured complex simulators in strict step-by-step accordance with the manual for flight operation of the aircraft (33 flights were performed with the participation of 66 pilots aged 30–55 years).Results. The data obtained indicate high levels of sensory loads in pilots, which are 9.5 times higher than the maximum values set by the Management of R 2.2.2006–05 and MI NTP. INT–17.01–2018. For 4 of the 6 evaluated indicators, sensory loads corresponded to class 3.2.Conclusions. The general assessment of the labor intensity class for members of flight crews of civil aviation aircraft on the set of sensory loads corresponds to harmful strenuous work of the 3rd degree (4 indicators of sensory loads with class 3.2). The results of the study are the basis for the approval of new hygienic criteria for establishing a class of working conditions for certain indicators of sensory loads for members of flight crews of the aircraft of the civil aviation (CA) with the addition of their class 3.3. A real assessment of the pilot’s labor intensity should be obtained only on the basis of time-based measurements performed as part of a step-by-step analysis of the aircraft’s flight operation manual.

Introduction. The profession of “machine operator in metalworking”, one of the most common professions in various industries, characterized by a large volume of abrasive operations, accompanied by dust formation, which creates a potential for the occurrence of diseases of the visual organ.The aim of the study is to provide a hygienic assessment of working conditions and occupational risk of visual organ pathology in metalworking machine operators.Materials and methods. Observation groups — machine operators for metalworking of two training groups (experience up to 5 years, experience of 6–20 years). Two comparison groups (administrative and technical personnel of the enterprise) are formed according to the same age-experience principle.Results. The working conditions of machine operators were classified as class 3.2. taking into account the severity and intensity of the work process and the noise level (80 dBA) in the workplace. Nitrogen oxide, carbon monoxide, and manganese were registered in the air of the working area in concentrations below the permissible concentration (PC), and the aerosol dihydroxide was registered above the PC in 25.8% of cases. In the main working groups, diseases of the anterior segment of the eye were more often registered, among which dry eye syndrome (DYS) prevailed (94.1%), chronic blepharoconjunctivitis (79.9%), persistent corneal opacification (21.7%). There was an increase in the prevalence of detected diseases with an increase in work experience (p≤0.05). In machine operators, the frequency of inhibition of lacrimal formation and decreased stability of the tear film was recorded significantly more often, with increasing work experience, the degree of violation of lacrimal formation and stability of the tear film increased. The chances of detecting pathology of the anterior segment of the eye in machine operators are 5.9 and 3.5 times higher than in the comparison group. There are different forces of connection, increasing with the increase of work experience in the profession, between the working conditions of machine operators and the occurrence of SHG (relatively strong), with chronic blepharoconjunctivitis and persistent corneal opacity (medium strength), which suggests the professional conditionality of this pathology.Conclusions. The results obtained suggest that the pathology of the anterior segment of the eye is professionally conditioned in metalworking machine operators and necessitate the introduction of preventive measures aimed at protecting the visual organ.
Comparative Study of Vegetable Biodiversity in Terai and Hilly Belts of Chitwan, Nepal
Authors: Devkota P. , Mishra S. 
Published: August 2020

The study was conducted to assess biodiversity and conservation aspects of vegetable crops in two different geographical areas of the Chitwan district. The household survey was carried out in Kailash (hill) and Nayabasti (terai) of Chitwan. Descriptive analysis, mean comparison, correlations, and biodiversity indices were used for data analysis. On the basis of biodiversity index, evenness, the adequate number of species, and Sorenson’s coefficient, open-pollinated (OP) (nonhybrid) vegetables were more diverse in hills than in terai, while hybrid vegetables are more diverse in terai than in hills. Hybrid vegetables were mostly grown in terai, where the use of chemical fertilizers and pesticides was also higher. OP vegetables dominated hilly areas. Gurung ethnic community had a significant role in the conservation of indigenous vegetable biodiversity. The primary source of seed was home storage in the case of OP vegetables in hills. However, in terai, agro-concerns were used as a significant source of seeds, followed by co-operatives. Co-operatives’ involvement was high in terai as compared to hills, but the role was not significant in vegetable farming.
In contrast, assistance in vegetable farming from agriculture service provider organizations was higher in hills as compared to terai. The major problem in vegetable farming was lack of irrigation in both areas, followed by market inaccessibility in hills, whereas climate change was rising as a problem in terai. Markets of produced goods were farm gate, local markets, and distant markets. A middleman mostly did the price determination of the products. Off-season vegetable farming was not practiced in the study areas. However, off-farm vegetable production was typical in hilly areas. Indigenous and OP vegetable biodiversity has been facing various challenges despite their roles in nutrition, indigenous knowledge promotion, and food security. Hence, it is suggested to strengthen government policy toward irrigation facility development, gene bank establishment, marketing facilities, and technology transfer and develop on-farm community based intense organizations for sustainable vegetable diversity conservation.
Features and properties of tangerine hybrids derived from distant hybridization (Citrus var. unshiu×Poncirus trifoliata)
Authors: Kulyan R. V. 
Published: August 2020

Among citrus crops in the subtropical zone of the of the Russian Federation Black Sea coast of Krasnodar Territory, only tangerines can be grown (Citrus reticulata Blanco var. unshiu Tan.). The expansion of planting is hindered by poor winter hardiness, that’s why breeders are faced with a task of creating new forms of mandarin that are maximally adapted to the extreme climatic conditions of the region. By using of a distant hybridisation it is possible to create such forms. Purposeful distant hybridization allows transferring the properties of one genus to another, which is leading to phenotypic and genotypic changes in hybrid generation. The article emphasizes the importance of distant hybridization. For the period 1995-2019, distant, recurrent and inter-hybrid hybridizations were carried out to create a new hybrid fund. The results of 19 combinations of crossing by using Poncirus trifoliata Raf., and hybrids which were obtained with the participation of this genus, as well as hybrid species: C.×insitorum, C.×citrangeqwa and the genus Fortunella Sw. Expanded forms were selected for further breeding with an early term of fruit ripening (I decade of October): YuМR-97; YuКR-22; ККR-27; ККR-22; МRКR-97-25; МRКR-97-25-1; КRМR-25-97, with later ripening (II decade of October: КVI-1, КVI-3, YuI-12 received with C. insitorum. Also with late maturity hybrids were revealed: КРF-25; КРF-22; МРF-97; TsКR-25; YuTs-8 with the immixture of Fortunella margarita and C. citrangeqwat. From recurrent and inter-hybrid hybridization were marked out promising forms of mandarin with positive features such as early ripening, average fruit mass and a high tasting assessment. The greatest breeding value is represented by hybrids derived with the immixture of the most frost-resistant ccongeners of the citrus Poncirus trifoliata, however, from 5.0 % to 6.25 % of promising samples were selected in these families. All forms have breeding value for further work on creating winter hardiness varieties of mandarin.
Ecological features of the association between mortality and determinants or salient risk factors of cardiovascular disease
Authors: Chukwuma Sr Chrysanthus 
Published: August 2020

The multifactorial emergence of the association between mortality and major risk factors of cardiovascular disease is not clearly established. Diverse countries have been monitoring and evaluating mortality and risk factors associated with cardiovascular disease as the levels and trajectories undergo continuous changes. Understanding the combined impacts of these alterations are crucial in taking precautionary measures in counteracting and managing cardiovascular disease. Mortality and risk factor data have been applied expansively for the monitoring and evaluation of cardiovascular disease issues and the spatiotemporal variations across populations. There are extant inequitable distribution of resources in the disparate regions and populations around the world in the quantification and analysis of the mortality, morbidity, risk factors or determinants of cardiovascular disease. The diagnosis of cardiovascular disease tends to be devoid of diagnostic tests of high specificity and sensitivity in certain instances. Poor diet is a leading etiologic factor of suboptimal health in cardiovascular disease. Diet, nutrition and scientific policy measures have accelerated, resulting in ambiguities, and also creating opportunities to obviate the excruciating health and economic burden in cardiovascular disease and other cardiometabolic disorders in vulnerable populations. These indicate that expansive spatiotemporal variations in the incidence between populations are attributable to inter alia certain contradictions in the modalities of event ascertainment, culture, and economic burden. This paper enhances and introduces novel issues, challenges and opportunities in the ecological presentations of the association between mortality and determinants or risk factors of cardiovascular disease.
