Published: May 2023

Background: Surfing is a sport that requires alternating high, medium, and low intensity at one time. Surfing combines three phases, namely paddling, pop-up, and wave-ride. The surf pop-up phase is characterized by a change from a paddling position to a standing position on the surfboard in one dynamic motion. During this transition, a surfer must move 75% of his body weight in less than one second. Pop-up movement is a unique challenge for the human motor system because it must be done quickly, with sufficient strength, on a moving and unstable surface that requires the readiness of the bio motoric component to avoid injury. This study aimed to see the relationship between core muscles, leg arches, hamstring, and lumbar flexibility on pop-up ability among surfers.

Methods: The research uses analytic observational with a cross-sectional approach. The number of samples was 80 people with inclusion criteria, men aged 20-40 years and at least one year of surfing experience. Core muscles were measured using the curl-up test, the footprint test measured leg arches, hamstring flexibility by the sit and reach test, lumbar flexibility by the modified Schober's test, and pop-up ability using the time to pop-up. The research was conducted in Badung regency.

Results: This study showed a significant and strong relationship between core muscles (r= 0,57, p-value< 0.001), leg arches (rs= 0.33-0.43, p-values= 0.009 - <0.001), hamstring and lumbar flexibility (rs= 0.31-0.50, p-values= 0.013 - <0.001) on pop-up ability among surfers.

Conclusion: There were significant relationships between the core muscles, leg arches, hamstring and lumbar flexibility on pop-up ability among surfers.

Соціально-особистісна криза при ідентифікації територіальних громад
Authors: Лазор Катерина
Published: May 2023

Саме національна ідентичність перетворює народ чи кілька народів, які проживають на певній території на націю, шляхом створення або поглиблення загальної культурної парадигми мислення, загального набору цінностей, ідеалів, спільного світогляду; які, своєю чергою, є тими ключовими і основними чинниками, які у результаті визначають нерозривний зв'язок нашого суспільства та держави. Саме національна ідентичність відповідає за цілісність суспільства, що визначає всю існуючу в державі політико-економічну систему. Національна ідентичність може виникнути в будь-якому соціумі, але для цього потрібна низка обставин – певний рівень соціально-економічного розвитку та цілеспрямована на загальний благоустрій політика еліт. Така важлива консолідація постає як процес інтеграції суспільства та його політичної системи довкола найважливіших суспільних цінностей, які втілені, передусім, у відповідних соціальних та політичних інститутах. Крім того, для успішного державотворення необхідно, щоб його складові компоненти були підготовлені до об'єднання досвідом попереднього історичного розвитку. Спроба ж об’єднання в єдине ціле складових частин часто веде до соціально-особистої кризи. На жаль, сьогодні практично немає соціальних груп населення, які почували б себе соціально захищеними, кризові стани сформували серед частини громадян зневіру та песимізм. Але є певні результативні методи, які можуть допомогти згуртуватися територіальній команді задля загального суспільного блага та розвитку усієї нації.

Positive temperature feedback loop in the catalytic cycle of heterogeneous catalysis
Authors: Kaplunenko Volodymyr , Kosinov Mykola
Published: May 2023

The mechanism of heterogeneous catalysis taking into account the influence of temperature is briefly considered in the development of the concept "electron as a catalyst". Here the catalytic cycle includes the heat transfer and electron generation besides the mass transfer. The mechanism of temperature influence in heterogeneous catalysis is realised through the generation of electrons in a positive feedback loop. This mechanism involves the Edison and Seebeck thermoelectronic effects. The catalytic cycle of heterogeneous catalysis is supplemented with a thermoelectronic stage. The thermoelectronic stage of catalysis involves heat transfer and electron generation. Energy transfer to the active centre of the catalyst is an integral part of the catalytic cycle. Energy transfer is considered as a positive temperature feedback loop. The generation of electrons in the positive feedback loop and their transfer to the reactants leads to an increase in reactivity of the reactants. The positive temperature feedback loop leads to an exponential (sigmoidal) dependence of the reaction rate.
Methods of determining the drought resistance of plants

Published: May 2023

This article presents methods for determining the drought resistance of plants at different stages of development. To determine drought resistance at the early stages of plant development, when creating breeding material, it is necessary to use the most accessible and common laboratory methods, which include modeling moisture deficit in solutions with increased osmotic pressure, which consists in the ability of germinated seeds of a variety to use low moisture reserves in the soil and predict resistance genotypes to soil moisture deficiency in the early stages of ontogenesis. At various stages of plant vegetation, recently, indirect assessment of drought resistance using physiological methods is becoming increasingly common. The most informative are methods of studying the water regime of leaves, namely: determination of tissue hydration, water deficit and water-holding capacity of leaves. Leaf water loss reflects the water status of plants and is key to their survival in drought conditions. The indicator of water-holding capacity characterizes the plant's ability to resist dehydration for a more or less long time, the length of which depends on its level. The water status of the plant is determined by the water deficit, which is an important indicator of drought resistance. Watering plants indicates that they are supplied with water, which is necessary for the flow of biochemical reactions (that is, for vital activity) and is one of the important indicators of the water regime of plants. The water content in the leaves indicates the attitude of the plants to the lack of moisture. To differentiate genotypes by drought resistance, various selection indices are used, based on the productivity of plants in optimal and stressful conditions for the selection of drought-resistant genotypes.

Cannabis sativa: Release of Volatile Organic Compounds (VOCs) Affecting Air Quality
Authors: Malabadi Ravindra B. , Kolkar Kiran P. , Chalannavar Raju K. , Mondal Moumita , L Lavanya , Abdi Gholamreza , Baijnath Himansu
Published: May 2023

This review paper highlights about the emission of volatile organic compounds (VOCs) of Cannabis plants. Volatile organic compounds (VOCs) are a large group of chemicals harmful to human health that are readily released into the atmosphere and participate in atmospheric photochemical reactions. Floral Volatile organic compounds (VOCs) are often involved in defence and pollinator attraction. Cannabis cultivation and consumption may lead to additional environmental impacts. Studies found out that Cannabis plants emit a significant amount of biogenic volatile organic compounds (BVOCs) which could cause indoor air quality issues. Indoor Cannabis cultivation is energy-consuming, mainly due to heating, ventilation, air conditioning, and lighting. Energy consumption leads to greenhouse gas emissions. Common compounds to all the tested hemp cultivars include β-myrcene, ϒ-caryophyllene, α-pinene, β-pinene and limonene, reflecting species specificity in the emission of these compounds. β-Myrcene was the most abundant compound in most of the outside hemp cultivars. The terpenes had an earthy musky, and fruity smell may contribute to the odour in Cannabis samples at the vegetative stage, flowering stage, and drying/curing stage. All hemp cultivars are the prolific emitters of terpenoids. The oxidation of highly reactive Biogenic Volatile organic compounds (BVOCs) from Cannabis plants can lead to the formation of ozone and secondary Volatile organic compounds (VOCs) (e.g., formaldehyde and acrolein). In hemp production, considerable odorous emissions occur during field retting. However, more research is needed to address how outdoor air quality is influenced by Cannabis cultivation facilities (CCFs) emissions.

Published: May 2023

According to studies conducted abroad, the HVAC system is to blame for 70% or more of all IAQ problems, and most of these problems are brought on by inadequate system care and maintenance. The lungs of a building, the air ducts, can accumulate deposits of construction grime, dust, tar from cigarettes, insects, smoke and other airborne contaminants. These distribution systems need to be inspected frequently in order to maintain the high efficiency of the air conditioners and lower effect losses. There is evidence that ventilation ducts in HVAC systems can accumulate dust and serve as breeding grounds for microbes even when they are operating normally. The building’s AC duct placement makes it impossible to clean by hand. An assessment of the current state of knowledge and comprehension about the employment of robots for air duct cleaning is what this review paper intends to do. The various varieties of air duct cleaning robots, as well as their capabilities and effectiveness in comparison to more conventional cleaning techniques, will be examined in this study. The cost, effectiveness, and safety of deploying robots to clean air ducts will also be discussed in this study, along with some of their benefits and drawbacks. The review will also look at the state of research and development in the area and identify any potential trends or difficulties in the use of robots for cleaning air ducts in the future. The paper will include a full evaluation of previous research on the subject, including studies, publications, and reports, as well as the methodology employed. The study will include findings and suggestions about the usage of robots for cleaning air ducts for facility managers, researchers, and air duct cleaning specialists. The paper’s overall goal is to present a thorough overview of the status of technology today and some of its prospective air duct cleaning applications.

De la foule aux masses : Philippe Soupault, grand-reporter dans l’Allemagne des années 30
Authors: Mallart Brussosa Myriam
Published: May 2023

Philippe Soupault, après son expulsion du surréalisme, se consacra au journalisme pour gagner sa vie. De 1932 à 1936, il se rendit régulièrement en Allemagne pour rendre compte des événements qui secouaient le pays voisin, comme reporteur envoyé spécial de journaux comme Vu et surtout Excelsior. Dans une indifférence générale, le poète devint un spectateur lucide de la montée du nazisme. Même si les questions politiques sont abordées, ce sont davantage les anonymes qui intéressèrent le poète. Afin de mesurer l’étendue du désespoir des Allemands et en quête du moindre signe de révolte, il observa la foule, interrogea étudiants, bourgeois, paysans, intellectuels, chômeurs. Au fil de ses articles et de la pression grandissante sur les journalistes étrangers, les dialogues disparurent de ses écrits : la foule prit peu à peu l’aspect de masse, symptôme d’une fracture entre le poète et le peuple allemand.
أثر حجم الشركة على العلاقة بين الملكية العائلية وسلوك التصاق التكلفة (دراسة تطبيقية على الشركات المدرجة في السوق المالية السعودية)

هدفت الدراسة إلى اختبار أثر الملكية العائلية على سلوك التصاق التكلفة، كما هدفت أيضًا إلى اختبار ما إذا كان هناك تأثير لحجم الشركة على العلاقة بين الملكية العائلية وسلوك التصاق التكلفة. ولتحقيق ذلك، تم اختيار 52 شركة من الشركات غير المالية المدرَجة بالسوق المالية السعودية خلال فترة خمسة أعوام، وذلك من 2017 إلى 2021. وقد توصلت الدراسة إلى وجود سلوك التصاق التكلفة بالشركات السعودية خلال فترة الدراسة، بالإضافة إلى وجود أثرٍ إيجابي للملكية العائلية على سلوك التصاق التكلفة، بما يدل على ارتفاع درجة التصاق التكلفة في الشركات العائلية المدرَجة بالسوق المالية السعودية مقارنةً بالشركات غير العائلية. وقد يرجع ذلك إلى وجود محدِّدات ودوافع لنمط الملكية العائلية من التحكم بالموارد تماشيًا مع التغيُّر في المبيعات. يُضاف إلى ذلك، أن أثر الملكية العائلية على سلوك التصاق التكلفة يختلف باختلاف حجم الشركة؛ إذْ تم التوصل إلى وجود علاقة معنوية بين الملكية العائلية وسلوك التصاق التكلفة في الشركات كبيرة الحجم مقارنةً بالشركات صغيرة الحجم. وأخيرًا، توصلت الدراسة إلى وجود تأثير معنوي للملكية العائلية على سلوك التصاق التكلفة في الفترة 2020-2021 (خلال جائحة COVID-19)، بالإضافة إلى وجود سلوك التصاق التكلفة بدرجة أكبر في الشركات العائلية كبيرة الحجم مقارنةً بالشركات الصغيرة. وتوصي الدراسة بضرورة تفعيل آليات الحوكمة بما يساهم في فرض رقابة أكثر صرامة على الشركات العائلية للحد من ممارسات هدر الموارد لتحسين الطلب، ومراقبة القرارات التي تقود بالنهاية لاحتكار المنتجات، بالإضافة إلى نشر التوعية بشأن السلوك غير المتماثل للتكلفة بين أصحاب المصلحة والمستثمرين في الشركات؛ حتى يكونوا على دراية بنمط التكاليف، وتقديراتها، ومحدِّداتها، ونتائجها على الربحية.

To minimize the missing seeds in groundnut planting, an Infra Red (IR) technology based sensor system was developed for a tractor drawn 9- row groundnut planter. This system could detect the number of groundnut seeds falling through a seed tube and provides visual and audible indications of missing drop(s). Laboratory evaluation of the planter with sensor system indicated that the variations of actual number of seeds dropped and display reading varied from 4.97% to 6.72% when operating speed varied from 2.5 km.h-1 to 3.5 km.h-1. The seed rates were 118.53 kg.ha-1 at 2.5 km.h-1, 100.10 kg.ha-1 at 3.0 km.h-1 and 93.20 kg.ha-1 at 3.5 km.h-1 operating speed. Under field condition, the planter without sensor system had lowest (22.60%) missing seeds at speed of 2.5 km.h-1, and highest (32.85%) missing seeds at higher speed of 3.5 km.h-1; while the planter with sensor system had 5.92% - 10.84% missing seeds with forward speed varying from 2.5 km.h-1 to 3.5 km.h1 . The missing index of seed thus, reduced by 16-22% with incorporation of the sensor device with the planter. With increase in forward speed, seed rate decreased irrespective of use of the sensor with the planter due to higher planter vibration as well as the seeds dropping back from the metering cells in the seed box before being discharged in seed tube. However, using the sensor system, no significant effect of speed on seed rate was observed.

Small-scale farmers in India and other developing countries have been using traditional stone local dehuller (chakki) for pulse milling, which is extremely slow and less effective. In this study, a low-cost and easy-to-operate farm-level pulse dehuller was developed to enhance farm mechanization in the processing sector. The performance of the developed dehuller was evaluated using three independent parameters, namely roller speed (19.47, 22.72, 25.97 m.s-1), feed rate (60, 90, 120 kg.h-1), and two emery rollers (Grit No. 40, Grit No. 50). To optimize the parameters, results were fitted in multi-level categorical general factorial design using design expert software. The maximum dehulling efficiency (84.62 %), maximum whole dehulled kernel (48.45 %), and minimum loss (2.78%) were obtained at roller speed of 19.47 m.s-1 and feed rate of 90 kg.h-1 with Grit No.50 roller. Compared to the traditional pulse dehulling process, the developed pulse dehuller could save 2.29 ₹ .Kg-1 in cost and 10.24 min.kg-1 in time.

In this study, test reports of materials used for soil/crop engaging components of agricultural machinery were collected from some Agricultural Machinery Testing Centres situated in different agro-climatic zones across India. The study revealed that only 39.87% and 37.72% of tested soil engaging components conformed with the standards of Bureau of Indian Standards (BIS) for material hardness and chemical composition, respectively. Furthermore, 38.5% fast-wearing components were made of high carbon steel, followed by medium carbon steel (33.0%), low carbon steel (25.0%), and tool steel (3.5%). It was observed that reputed manufacturers used high carbon and tool steel for fabricating critical components, and also heat-treated them for getting desirable product properties. Accordingly, four types of steel (D-2, M-4, EN-31, EN-8 with heat treatments) easily available in market were used for fabricating soil engaging blades suitable for conservation agriculture (CA) machinery. Wear test results showed lowest wear rate for D-2 and highest for EN-8 steel. Furthermore, D-2 also had highest relative life, and found most suitable for manufacturing soil engaging components of conservation agriculture machinery.

The role of irrigation is important in mitigating the challenges involved in food production under the changing climate scenarios. Adequacy and equity in water distribution are the primary concern regarding the performance of any irrigation scheme. Conveyance efficiency and two adequacy indicators, namely, Relative Water Supply and Adequacy were used to evaluate the performance of Chalakudy River Diversion Scheme (CRDS) located in central Kerala, India, in the present study, Water withdrawal data collected from Irrigation Department, and data collected from field measurements of canal discharge and seepage loss were used in the study. Irrigation requirement of the canal command area was worked out using the FAO’s CROPWAT 8.0 software. The results revealed that the average annual irrigation demand of the CRDS command area is 46.90 Mm3. Measured flow rate through the canal system showed that the flow decreases towards the tail end. Loss of water through seepage from the canal was high in the irrigation scheme due to the highly damaged condition of canal lining and poor maintenance. The CRDS canal system’s overall conveyance efficiency was found to be 51%. Based on Relative Water Supply and Adequacy Indicator, functioning of the irrigation scheme falls in the category of ‘fair’. Apart from proper repair and maintenance of canal system, conjunctive use of groundwater and canal water for irrigation is suggested towards the tail reaches to alleviate irrigation water inadequacy problems in the CRDS command area.

A field experiment was conducted during consecutive Rabi seasons of 2019-2020 and 2020-2021 in coastal saline soils at Khar Land Research Station, Panvel, Maharashtra, India to study the effect of different sowing dates and irrigation levels on the production potential of field bean. The experiment was laid out in factorial randomized block design (FRBD) with four replications, comprising three dates of sowing viz., immediately after harvest of paddy (D1), 10 days after harvest of paddy (D2), and 20 days after harvest of paddy (D3); and three irrigation levels viz., no irrigation (I0), one irrigation at flowering (I1), and one irrigation each at flowering and at pod formation (I2). The results showed that the treatment D1 recorded significantly higher seed yield of field bean (915 kg.ha-1) over D2 (713 kg.ha-1) and D3 (605 kg.ha-1). Among the irrigation levels, treatment I1 resulted in significantly higher seed yield of field bean (856 kg.ha-1) over I2 (726 kg.ha-1) and I0 (650 kg.ha-1). The treatment combination I1D1 produced significantly higher seed yield of field bean (1065 kg.ha-1) with higher net realization (1,06,500 ₹.ha-1), net income (55,222 ₹.ha-1) and benefit cost ratio (2.08). Both sowing date and irrigation level played important role in management of root zone soil moisture and soil salinity which influenced the seed yield. Sowing of field bean immediately after the harvest of paddy and providing one irrigation at the time of flowering is recommended to obtain better yield and returns from the field beans cultivated in Konkan region of Maharashtra.
