Adoption of Improved Buffalo Husbandry Practices in Peri-Urban Areas of Surat City, Gujarat

The present study was carried out in the peri urban areas of Surat city of Gujarat to find out the adoption of improved buffalo husbandry practices. A random sample of 50 buffalo farm owners were selected and interviewed for the interview schedule prepared about adoption of improved dairy husbandry practices in six major aspects of housing, feeding, breeding, health care, milking and calf rearing management was studied. Housing in separate located place (100%), providing proper floor space (98%) and proper height and ventilation (90%) were more adopted in housing practices. Provision of clean and fresh drinking water (100%), feeding extra ration to advance pregnant animals (64%) and feeding balance concentrate mixture on the basis of milk production (64%) were more adopted in feeding management. In adoption of breeding management, keeping watch on oestrus cycle and heat symptoms of animals (100%), artificial insemination of animals (100%) and practicing pregnancy diagnosis between 60-90 days after service (91%) were more adopted by buffalo owners. Observing animals daily for signs of sickness (100%), timely and regularly vaccination (100%) and treatment of reproductive disorders (75%) were more adopted by respondents in health care management practices. In milking and calf rearing practices, washing pails and hands before milking (100%) and regularity in milking time (100%), early solid feeding (100%) and milk feeding to calves up to three months of age (96%) were more adopted by the buffalo owners.

Dynamics of elevated dodecane jets in crossflow at supercritical pressure

In advanced aero-engines, kerosene is often transversely injected into the combustor at supercritical pressure, where the shorter jet penetration depth may result in poor mixing and the local hot spots near the combustor wall. Elevating the jet nozzle is proposed to remedy these issues, where the flowfield complexity increases as a result of the intricate interactions among the jet, crossflow, and stack wake. The distinct flow dynamics of elevated dodecane jets in crossflow (EJICF) at supercritical pressure are numerically investigated using large eddy simulation. The effects of various parameters, including ambient pressure, elevation stack thickness, and stack height are studied. The results reveal that, the jet-wake recirculation bubble is prominently evident at low supercritical pressure, attributed to the strong real-fluid effect resulting from significant density stratification in the jet's upstream shear layer. Analysis of streamline patterns and vorticity budgets underscores the role of the real-fluid effect in delaying the shift of the flow pattern from the transitional regime to the jet-dominated regime. Increasing stack thickness mitigates the impact of jet upshear effects and has the potential to eliminate the lock-in phenomena between jet wake and stack wake. A reduction in stack height leads to the diminishment of the stack wake vortex shedding. In contrast to conventional JICF, the EJICF configuration exhibits a heightened tendency for recirculation bubble formation in the jet wake region. An analysis of spatial mixing deficiencies demonstrates that incorporating an elevation stack with proper thickness and height can dramatically improve the jet-crossflow mixing efficiency.

Russian Legal Education: The Present and the Future

The paper examines the issues of modern Russian legal education that developed under the auspices of the Bologna educational system. Since the introduction of the Bologna rules, which Russian innovators interpreted exclusively in a subjective way, domestic education has not improved. On the contrary, all those positive characteristics that education possessed within the Russian borders began to gradually disappear, striving to blindly copy foreign variants. Many problems have appeared in education, mainly due to the departure from Russian cultural values and the attempt to replace them with foreign standards. As a result, educational levels have appeared, which, in theory, require an original educational approach. But such an approach requires saturation of the curriculum material of one level to the detriment of another, which is hardly feasible. It is emphasized that Russian traditions in education, their reanimation, including a return to specialist’s degree, are able to raise the educational level of Russia to the proper height again. The paper briefly comments on the efforts of Russian scientists, mainly professors of the Higher School of Economics, in the field of improving the educational process. The problem of the effectiveness of lecturing in conditions of simplified information acquisition is raised. As the main sketch from this area, the author gives a review of the work by Maria S. Shakaryan, who proposed a certain algorithm for reading introductory lectures.

Pruning as a production factor of the cacao tree (Theobroma cacao l.)

Pruning is one of the main tasks that must be taken into account in the management of a cacao plantation. Its proper application stimulates production, facilitates the harvest of ripe fruits and the removal of fruits and organs diseased by Cacao frosty pod rot and Witches´ Broom. Essentially, pruning consists of removing suckers, branches that grow downwards and to the sides, intertwined branches, twigs that form inside the crown, and the tipping of upper branches to preserve the proper height of the trees.

Potential and Limitations of Research Battery Cell Types for Electrochemical Data Acquisition

AbstractDeveloping new electrode materials and/or electrolytes for lithium‐ion batteries requires reliable electrochemical testing thereof. For this purpose, in academic research typically hand‐made coin‐type cells are assembled. Their advantage is a rather cheap and facile assembly, and possibility to prepare full‐cells as well as half‐cells, meaning cathode‐anode or electrode‐elemental lithium configurations. Critical parameters for testing data quality and the potential and limitations of cell tests in half‐cell configuration are discussed. Further, on the basis of a round robin test, using highly homogenous commercial electrodes, where graphite is used as anode and LiNi0.33Mn0.33Co0.33O2 (NMC111) as the cathode material, it is shown that data acquired is highly influenced by assembling parameters. Besides known variables such as the amount of electrolyte or electrode positioning, the proper height of the cell stack and the steel grade of the housing material are identified as decisive variables. Finally, it is demonstrated that under proper conditions coin cells can show a great cycle stability of >2200 cycles using 1 C as dis‐/charge rate while retaining a capacity of 80 %. This performance is close to pouch‐type cells containing the same electrodes and electrolyte, which were used as a benchmark system and showed >3500 cycles of lifetime.

A simple KPFM-based approach for electrostatic- free topographic measurements: the case of MoS2 on SiO2

A simple implementation of Kelvin probe force microscopy (KPFM) is reported that enables recording topographic images in the absence of any component of the electrostatic force (including the static term). Our approach is based on a close loop z-spectroscopy operated in data cube mode. Curves of the tip-sample distance as a function of time are recorded onto a 2D grid. A dedicated circuit holds the KPFM compensation bias and subsequently cut off the modulation voltage during well-defined time-windows within the spectroscopic acquisition. Topographic images are recalculated from the matrix of spectroscopic curves. This approach is applied to the case of transition metal dichalcogenides (TMD) monolayers grown by chemical vapour deposition on silicon oxide substrates. In addition, we check to what extent a proper stacking height estimation can also be performed by recording series of images for decreasing values of the bias modulation amplitude. The outputs of both approaches are shown to be fully consistent. The results exemplify how in the operating conditions of non-contact AFM under ultra-high vacuum (nc-AFM), the stacking height values can dramatically be overestimated due to variations in the tip-surface capacitive gradient, even though the KPFM controller nullifies the potential difference. We show that the number of atomic layers of a TMD can be safely assessed, only if the KPFM measurement is performed with a modulated bias amplitude reduced at its strict minimum or, even better, without any modulated bias. Last, the spectroscopic data reveal that certain kind of defects can have a counterintuitive impact on the electrostatic landscape, resulting in an apparent decrease of the measured stacking height by conventional nc-AFM/KPFM compared to other sample areas. Hence, electrostatic free z-imaging proves to be a promising tool to assess the existence of defects in atomically thin TMD layers grown on oxides.

A micro-vibration-driven direct ink write printing method of gallium–indium alloys

Combining liquid fluidity and metallic conductivity, gallium–indium (Ga–In) alloys are making a splash in areas such as stretchable electronic circuits and wearable medical devices. Due to high flexibility, direct ink write printing is already widely employed for printing Ga–In alloys. Currently, pneumatic extrusion is the main method of direct ink write printing, but the oxide skin and low viscosity of the Ga–In alloys make it challenging to control after extrusion. This work proposed a method for direct ink write printing of Ga–In alloys utilizing micro-vibration-driven extrusion. Micro-vibration reduces the surface tension of Ga–In alloy droplets and avoids the appearance of random droplets during printing. Under micro-vibration, the nozzle tip pierces the oxide skin to form small droplets which have a high moldability. The droplet growth process is significantly slowed down by optimizing suitable micro-vibration parameters. Therefore, the Ga–In alloy droplets with high moldability can be maintained at the nozzle for a long period, which improves printability. Furthermore, better printing outcomes were obtained with micro-vibrations by choosing the proper nozzle height and printing speed. Experiment results demonstrated the superiority of the method in terms of Ga–In alloys extrusion control. With this method, the printability of the liquid metals is enhanced.

Reducing Environmental Hazards of Prismatic Storage Tanks under Vibrations

Regular operation, pre-repair and repair work on tanks, as well as outflows of oil products and other flammable liquids under the influence of seismic loads, fires and explosions on tanks are the source of technogenic impact on the environment. Therefore, the influence treatment of the fluctuations and vibrations on the storage tanks for environmentally hazardous liquids and the assessment of reducing the load on nature is a very relevant scientific and practical issue to improve the environmental safety of areas adjacent to the tanks. This paper treats free and forced liquid vibrations in prismatic tanks filled with an incompressible ideal liquid. The developed method allows us to estimate the level of the free surface elevation in prismatic tanks under suddenly enclosed loadings. The proposed method makes it possible to determine a suitable place with a proper height for installation of the baffles in tanks by using numerical simulation and thus shortening the expensive field experiments. The proposed approach could be applied to various environmentally hazardous liquids. This will increase the environmental safety level of the territories adjacent to stationary tanks with environmentally hazardous liquid. It will also be possible to prevent emergencies.

Revisional Asian Blepharoplasty of the High Eyelid Fold: Tarsus-Orbicularis Fixation Combined With Orbital Fat Repositioning Technique.

Abnormally high eyelid fold is a common unsatisfactory esthetic outcome after double eyelid surgery. At present, successful correction of high eyelid fold among Asians remains one of the most challenging procedures for eyelid plastic surgeons. This article aims to propose a novel technique for correcting high eyelid fold to improve the cosmetic outcomes and patient satisfaction. This is a retrospective study of 86 patients (154 eyelids) with high eyelid folds who underwent revision blepharoplasty. A new proper height incision line was designed during the operation, and the adhesion between skin and levator aponeurosis was fully released. The residual orbital fat was adequately separated. If necessary, orbital fat from lower eyelid will be harvested for free fat grafting. The tarsus-orbicularis fixation combined with orbital fat repositioning technique was used to create a double eyelid fold and reconstruct the gliding zone. The surgical outcome and patient satisfaction are reviewed. Among the 154 eyelids with high eyelid fold, mean lid crease height decreased from 9.8mm preoperation to 6.8mm ( P <0.001) and mean pretarsal show decreased from 3.5mm preoperation to 1.9mm 6 months postoperation ( P <0.001). The esthetic outcome was fully satisfied in 78 patients (90.7%) and basically satisfied in 6 patients (7.0%). Two patients (2.3%) were unsatisfied because of ptosis undercorrection in 1 patient and asymmetry in the other. They both got satisfied results after reoperation. The tarsus-orbicularis fixation combined orbital fat repositioning technique is a simple and effective method to correct high eyelid folds with high satisfaction and rare complications.

Mothers’ Perceived Susceptibility and Severity of Maternal Behavior in Stunting Prevention

BACKGROUND: Nutritional problem is still a significant public health issue worldwide, and Indonesia is not exempted. Stunting is the failure of a child to grow to the proper height of their age due to unbalance nutritional intake (more calories and less protein) when they are still in the womb, baby, and toddlers. The mother’s lack of awareness about the susceptibility and severity of the stunting is the contributing factor. AIM: Purpose of this study is to investigate mothers’ perceived susceptibility and severity toward stunting and their association with mothers’ behavior to prevent stunting. METHODS: It is a quantitative study using an analytical observation design with a cross-sectional approach. This population is 120 mothers with under 5 years of children in East Surabaya Health Center, Indonesia. They were all taken as research samples. The independent variables are perceived susceptibility and severity of stunting, whereas stunting prevention is the dependent variable. The Likert scale is used to develop a questionnaire as a data collection tool. The logistic regression test was carried out to identify mothers’ perceived susceptibility and severity level to protect their children from stunting. RESULTS: The study found that mothers generally have a good perception of the susceptibility and severity of stunting. The logistic regression test shows that the value of significant = 0.000 for the susceptible variable and significant = 0.003 for the severity factor. CONCLUSION: The study concluded that the strong association between mothers’ perception of susceptibility and severity of stunting affects their stunting prevention behavior. SUGGESTION: The study advises mothers to improve their awareness of the danger of stunting and take necessary action to prevent it. Health promotion efforts should focus on empowering and enhancing the participation of mothers to take pre-emptive steps to prevent stunting.

AIMS: to assess radiological and clinical outcomes, in terms of safety and efficacy, of symptomatic vertebral fractures with and without posterior wall and\or both endplates involvement, treated with vesselplasty technique (Vessel-X, Dragon Crown Medical Co., Ltd Shandong, China).&#x0D; MATERIALS AND METHODS: We retrospectively evaluated 66 Patients who underwent 92 vesselplasty procedures, performed for the treatment of symptomatic vertebral body fractures from March 19 to September 2020. We divided the fractures in two subgroups: 36 vertebral fractures with posterior wall and/or both endplates involvement, which we defined complex, while all the others were defined simple. Numerical Rating Scale (NRS) and Oswestry Disability Index (ODI) values has been registered 1 day before the procedure and at 1, 6 and 12 months follow-up. We also evaluated vertebral height restoration by comparing pre-interventional with post-interventional imaging.&#x0D; RESULTS: 92 vertebrae were treated (58 lumbar, 34 thoracic), with 24 multilevel procedures. We observed a technical success rate of 100%, without major complications; a single case of asymptomatic paravertebral cement leak was reported. Both simple and complex subgroups registered a significative statistical difference in NRS and ODI between preoperative and at 1, 6 and 12 months (p 0.05). A significant statistical difference was demonstrated in vertebral height comparing pre-operative and post-operative data (p 0.05). No significant difference in vertebral height restoration was observed between simple and complex vertebral fractures groups.&#x0D; CONCLUSIONS: Vesselplasty represents a safe and effective technique for the treatment of both simple and complex painful vertebral fractures, granting a significant reduction of symptoms, excellent cement leakage control and proper vertebral height restoration.

Dual-polarized elliptic-H slot-coupled patch antenna for 5G applications

A dual-polarized, slot-coupled dielectric patch antenna design is presented in sub-6 GHz for 5G base stations. Proposed antenna is implemented using two dielectric patch layers (main patch and parasitic patch) above a feeding line layer. Excitation is realized by crossed elliptic-H slots in order to create orthogonal ± 45$^{\circ}$ polarizations. Through the use of patches at proper heights together with elliptic-H slots, significant improvement in impedance bandwidth, matching level, isolation and front-to-back ratio is acquired. Prototype antenna has an impedance bandwidth of 18.5\% (3.23--3.85 GHz) for $ S_{11} $, $ S_{22} $ $

Flutter Modelling and Computation of a Flying Wing Aircraft

Flying wing aircraft has many encouraging advantages, but there still were many unsteady aerodynamic uncertainty of the structures. Dynamic stability is a most significant analysis object. This paper wants to propose the flutter characteristic of a real flying wing aircraft. Firstly, an efficient finite element modelling method was taken to find basic dynamic features of the presented aircraft with effective mode analysis. Typical dynamic characteristics including bending and twisting modes of the structure were analyzed to propose possible dynamic stability of the aircraft. Secondly, a frequency domain fluid-structure interaction method was proposed to solve flutter analysis problem of the aircraft. With different heights and Ma number, flutter features of the aircraft were presented. It was seen from the computational results that dynamic stability analysis is necessary for the flying wing aircraft with proper flight velocity and height. The present dynamic modelling method and flutter computation process can give an effect reference for the design of flying wing aircraft. Also it can provide useful suggestions for existing flying wing aircraft structures.

The Intrinsic Thermodynamic Difficulty and a Step-Guided Mechanism for the Epitaxial Growth of Uniform Multilayer MoS2 with Controllable Thickness.

Multilayer MoS2 shows superior performance over the monolayer MoS2 for electronic devices while the growth of multilayer MoS2 with controllable and uniform thickness is still very challenging. It is revealed by calculations that monolayer MoS2 domains are thermodynamically much more favorable than multilayer ones on epitaxial substrates due to the competition between surface interactions and edge formation, leading accordingly to a layer-by-layer growth pattern and non-continuously distributed multilayer domains with uncontrollable thickness uniformity. The thermodynamics model also suggests that multilayer MoS2 domains with aligned edges can significantly reduce their free energy and represent a local minimum with very prominent energy advantage on a potential energy surface. However, the nucleation probability of multilayer MoS2 domains with aligned edges is, if not impossible, extremely rare on flat substrates. Herein, a step-guided mechanism for the growth of uniform multilayer MoS2 on an epitaxial substrate is theoretically proposed. The steps with proper height on sapphire surface are able to guide the simultaneous nucleation of multilayer MoS2 with aligned edges and uniform thickness, and promote the continuous growth of multilayer MoS2 films. The proposed mechanism can be reasonably extended to grow multilayer 2D materials with uniform thickness on epitaxial substrates.

Design and Analysis of Flood Resisting Residential Building: A Case Study in Malappuram-KERALA

Structural analysis and design are the backbone or the crucial aspects in civil engineering. The foremost important requirement in civil engineering is to design all of the members related to a building such as slabs, beams, columns and footings. The residential building is situated in Malappuram district of Kerala state. Flooding and its adverse effects on the structure has been a cause of concern affecting the safety of humans for a major cause of time. This paves way for the sustainability constraint and the concerns over climatic change and the worry of environmental causes are also taken as a major concern in people's minds. Flood resistant buildings must comply with all major health and safety constraints and must begin from the primary planning and must continue in each of the upcoming stages. Structural analysis and designing of the building is done according to the relevant IS codes and STAAD.Pro software. There are higher chances and risks embarking greater polls for the structure to fail due to waterlogging or the pressure imbibed due to the movement of course of water thus paving out the environmental constraint. Proper height must be allowed for the retaining walls, taking into account the future floods of greater magnitude and higher flow. Manufacturability constraint accounts to improper design of structural elements. Taking into account all these constraints proper designing must be done as per IS 456:2000 and modelling using REVIT Architecture.

Comparison of Characteristics of Posyandu Services During the Covid-19 Pandemic Before and after Revitalization of Posyandu and Empowerment of Cadres through Integrated Program

The Covid-19 pandemic has disrupted maternal and child health services at the Integrated Health Center (Posyandu). Posyandu play central role for early detection of stunting when a child fails to grow to the proper height for his or her age inchildren under five (toddler). Currently Posyandu target to reach at least 80% attendance rate has also not met. Before pandemic, Posyandu has started to even become less attractive, as evidenced by the increasing number of community absenteeism at the Posyandu, from 25.5% (2007) to 34.3% (2018). Weak implementation of Posyandu and the lack cadres’ ability in carrying out their task as one of the factors for the low level of community participation. We aim to provide a pilot intervention to address these issues. The purpose of this study was to compare the characteristics of Posyandu services during the Covid-19 pandemic and after Covid-19 pandemic with interventions given in the form of revitalizing posyandu and empowering cadres. This research method useds descriptive research with survey research design. The population in this study were 85 targeted children in four 4 Posyandus across Ende district. The sampling technique is simple random sampling. The results showed that before the intervention 78.8% of respondents received more than one type of health service and increased to 80% after the intervention. The visiting frequency to posyandu increased from 57.6% to 82.5%, There is a slight decrease in Posyandu’s attendance due to Pandemic, from 77.6% to 75%. It can be concluded that the intervention in the form of revitalizing posyandu and empowering cadres through an integrated program is one solutions to provide improvement in Posyandu services.

Ergonomic Consideration in Pillow Height Determinants and Evaluation.

(1) Background: Sleep problems have become one of the current serious public health issues. Pillow height affects the alignment of the cervical spine and is closely related to the mechanical environment of the cervical spine. An appropriate pillow height can provide adequate support for the head and neck to reduce the stress in the cervical spine and relax the muscles of the neck and shoulder, thereby relieving pain and improving sleep quality. (2) Methods: We reviewed the current trends, research methodologies, and determinants of pillow height evaluation, summarizing the evidences published since 1997. In particular, we scrutinized articles dealing with the physiological and mechanical characteristics of the head-neck-shoulder complex. (3) Results: Through the investigation and analysis of these articles, we presented several quantitative and objective determinants for pillow height evaluation, including cervical spine alignment, body dimension, contact pressure, and muscle activity. The measurement methods and selection criteria for these parameters are described in detail. However, the suggested range for achieving optimal cervical spine alignment, appropriate pressure distribution, and minimal muscle activity during sleep cannot yet be identified considering the lack of sufficient evidence. Moreover, there remain no firm conclusions about the optimal pillow height for the supine and lateral positions. (4) Conclusions: A comprehensive evaluation combining the above determinants provides a unique solution for ergonomic pillow design and proper pillow height selection, which can effectively promote the public sleep health. Therefore, it is necessary to develop a reasonable algorithm to weigh multiple determinants.

Research on the Decompression Effects of Shaft Explosion-Proof Door at Different Lifting Heights

To study the decompression effects of shaft explosion-proof door at different lifting heights, this paper designed the gas explosion testing system. Based on the test results, this paper made a numeric analysis of the change regularities of the shock wave overpressure when the shaft explosion-proof door was lifted at different heights. Finally, this paper determined the proper lifting height of the shaft explosion-proof door and put forward the active decompression concept. The research showed that (1) the shock wave overpressure at the explosion-proof door decreased in a power exponential relationship as the lifting height increased. When the lifting height increased from 0 cm to 5 cm, the peak overpressure at the explosion-proof door decreased from 36.06 kPa to 22.47 kPa, dropping by 37.7%. When it was lifted at a height of 40 cm, the overpressure dropped to 11.20 kPa and the decompression reached 68.9%. (2) The overpressure at the ventilator decreased in a power exponential relationship as the lifting height increased. When the lifting height of the explosion-proof door increased from 0 cm to 5 cm, the decompression ratio reached the maximum 18.4%. After that, the decompression effect became worse and worse. (3) The explosion-proof door could depressurize and protect the ventilator at gas explosion but with limited effects. To protect the ventilator and the explosion-proof door to the maximum, it was suggested that the pressure sensor was set up somewhere in the mine where the gas explosion is likely to occur. In this way, the explosion was sensed in time and the explosion-proof door could be actively lifted for decompression. This paper was of great guiding significance in optimizing the design of the explosion-proof door equipment, reducing the loss of gas explosion accidents as well as carrying out the emergency rescue.

According to Sternberg'y (Zeit, f. Geb., Bd. 84), the microbes found in the female genital canal remain innocent saprophytes only as long as the body's defenses are at the proper height, with the weakening of the same microbes can in a short time, acquire the properties of parasites and infect the body.

Numerical study of liquid sloshing in 3D LNG tanks with unequal baffle height allocation schemes

Tank sloshing is a hotspot issue in the design of a vessel. The liquid in a partially filled tank sloshes along with the ship. Except the negative effects to the stability of the ship, the sloshing phenomena may damage the wall of the tank due to the attacking pressure. Therefore, the control of the tank sloshing is one of the researches emphasizes. While the baffles in tanks have positive effect on the control of the tank sloshing, so we compare influence of different baffle factors, such as the number of baffles, the liquid rate, excitation frequency. Then compare the effect by investigating the wave height, spectrum, hydrodynamic force and the velocity vector. The simulation processes are executed in STAR-CCM+. In the numerical simulation of the tank sloshing, we obtained a deformation at the peak of the wave height by adjusting the factors in the k−ε model, which is more approximate to the experimental results. Moreover, in order to obtain the wave height through the direct measurement of the liquid height, we derive the relationship between the liquid height and the wave height. Finally, we proposed an unequal baffle height (UBH) allocation scheme. Then compared the performance of UBH scheme with the equal baffle height (EBH) scheme which has the same baffle number under the condition that the total height of all baffles is the same. The performance of different baffle height allocation schemes are compared by setting different baffle height gradient. Numerical simulation results showed that the allocation of the baffle height has effect on the control of tank sloshing. The UBH scheme with the proper baffle height gradient performs better than the EBH scheme when we take no account of the baffle strength.
