Nepal and COVID-19: A strange case and the Dilemma
Authors: Thapa Amit
Published: April 2020

COVID-19 caused by SARS-CoV-2 started as an outbreak in Wuhan, China in December 2019. Despite strict measures put up by China, its silent but highly contagious nature led to widespread dissemination which made World Health Organization (WHO) declare it as a global pandemic on 11 March 2020. With 152,523 people dying among 2,347,060 affected in 213 countries and territories due to the disease, nations are fighting to “flatten the curve of epidemic.

The situation in Nepal has been rather strange. Due to its geographical proximity to China and porous borders, WHO quickly declared it a high-risk country for COVID-19, however, only few cases had been reported till date with no record of local transmission (except for one with direct contact) even after testing 8081 samples. It appears as if Nepal has been able to keep the pandemic in early phase for this long!

Authors: Sangoli Shashank
Published: April 2020

Background: Cervical disc disease and spondylosis is a common pathological entity and is characterised by increasing degeneration of the intervertebral disc with subsequent changes in the bones and soft tissues.

Aim: To determine functional outcome of anterior cervical discectomy with fusion and plating in single level degenerative cervical disc prolapse.

Methods and Materials: This study was done at the Department of Neurosurgery, Medical Trust Hospital, Kochi over a period of three years after receiving institutional ethical clearance. 60 patients aged between 20 to 60 years, both male and female, who had degenerative disc disease with single level herniation with worsening or non-improving neck pain with radiculopathy, corresponding neurologic deficit, who were admitted in our unit were included in the study. Baseline data like name, age and gender were recorded for all the patients included in the study. Clinical examination consisted of history, thorough neurological examination and corresponding radiological evaluation. A visual analogue scale was used to make a subjective assessment of the patient’s complaints (pre-operative and post-operative).

Results: A total of 60 patients were included in the present study, among them 40 were males and 20 were females with male to female ratio of 2:1. All of them showed a significantly better improvement in visual analogue scale score of neck pain and UE radicular pain (p<0.05). The post-operative improvements in the clinical presentation of the patients were also noted.

Conclusion: A single level of anterior discectomy and cervical fusion for degenerative cervical disc prolapse with and without radiculo-myelopathy is an effective, successful and safe operation with minimal complication rate. The visual analogue scale following surgery was significantly improved.
Open surgery of complex long segment (giant) glomus spinal arteriovenous malformation
Authors: Deo Alok , Aryal Sameer , Sharma Gopal Raman
Published: April 2020

Spinal arteriovenous malformation occurring in the pediatric population (under 15 years) initially complain of pain as the first symptom which is often over looked. In almost all, diagnosis is delayed resulting in weakness. Angiogram provides correct diagnosis in all cases. Radical microsurgical excision tends to offer best long-term result.

Here we present a 7-year-old girl referred to us for lumbar puncture with provisional suspicion of meningitis. She had history of fever for two days and signs of meningism were present. On examination, she was stable and had complains of headache. Her previous history suggested she had continuous backache since childhood and had visited multiple centers previously for the problem. A detailed work up revealed a long segment spinal space occupying lesion. CT angiogram showed spinal arteriovenous malformation. Laminoplasty and open microsurgical excision of arteriovenous malformation was performed. Her hospital stay was uneventful and was discharged in stable condition. Early recognition, accurate diagnosis and prompt surgical treatment may result in significant improvement of neurological function.

Authors: Kaplychna Liudmyla
Published: April 2020

У статті вперше проаналізовано ліро-епічні твори О. Гай-Головка «Коханіяда», «Майдан св. Софії» з точки зору жанрово-стильових особливостей моделювання «вічної теми». У цьому контексті осібно закцентовано на зображально-виражальних засобах, які усебічно розкривають талант поета. Засо­би образності мови сприяли літератору втілити в словесну форму конкретні уяв­лення про предмети і явища, увиразнити особисте ставлення до них. Доведено, що тропи в поемах виконують роль художнього обрамлення, художньої довершеності, адже слова і словосполучення, вжиті у переносному значенні, корелюють естетичну функцію та художню реальність й у такий спосіб ємко розкривають світ і людину в ньому.

Authors: Belokobylskij S.A. , Lin Ch.-Sh.
Published: April 2020

A short review of the genera Ecphylus Foerster, 1863 and Sycosoter Picard et Lichtenstein, 1917 is given. A new species, Ecphylus lini sp. nov., from Taiwan Island is described. Unlike all other species in the genus, it has the strongly striate second metasomal tergite. The species was reared from the bark beetle Scolytus japonicus Chapuis, 1875 (Coleoptera: Curculionidae: Scolytinae). The genus Ecphylus is recorded in the Oriental fauna for the first time. The following new combinations are suggested: Sycosoter alboapicalis (Belokobylskij, 1993), comb. nov.; S. brevitergum (Belokobylskij, 1993), comb. nov.; S. conformis (Belokobylskij, 2009), comb. nov.; S. hahajimus (Belokobylskij et Maeto, 2008), comb. nov.; S. konishii (Belokobylskij, 2009), comb. nov.; S. medianus (Belokobylskij, Iqbal et Austin, 2004), comb. nov.; S. subtropicalis (Belokobylskij, 2009), comb. nov.; and S. topali (Papp, 1993), comb. nov.

Published: April 2020

Geographic distribution and habitat preferences of Saxicola rubicola rubicola (Linnaeus, 1766), S. maurus variegatus (S.G. Gmelin, 1774), and S. m. armenicus (Stegman, 1935) inhabiting the Caucasian Isthmus and adjacent areas are described in detail. We examined the individual, sexual, age, seasonal and geographical variations of seven main diagnostic features of both plumage and morphometrics (exactly, the length of wing and tail) using 381 skin specimens. Substantially improved diagnoses of S. m. variegatus and S. m. armenicus are provided. After a thorough examination of the materials and history of the expedition of Samuel Gmelin in 1768–1774, and his description of Parus variegatus, it was concluded that the type locality of this taxon was the vicinity of Shamakhi in Azerbaijan not Enzeli in North-Western Turkey. It is also shown the fallacy of the recently proposed attribution of the holotype of the northern subspecies S. m. variegatus to the southern taxon S. m. armenicus and synonymisation of these names, as well as the replacement of the name S. m. variegatus by its junior synonym S. m. hemrichii Ehrenberg, 1833 for the northern subspecies.

Abstract: Bojongsoang Village as one of the areas in Bojongsoang District is a densely populated area, where there is a shift and transfer of green functions to built up land (such as: new housing, industry / factories and others). Land for the green lane has become built up land (built into a house), this makes what should be productive land become unproductive land. In addition, with the increasing pressure of green land into developed land, demanding the community to optimize the land they have as productive land.The understanding of space which is only understood as a horizontal plane as land that can be used as productive land must be changed. Space is not only implemented in the horizontal plane but can also utilize the vertical plane to have high flexibility as land that can be processed as productive land. The urban farming model as an urban agriculture program that has long been developing is a potential activity in supporting the sustainability and survival of a district.The purpose of this study is to determine the Eco Village model in the Paralon village area as an Eco-Architecture concept in supporting the development of Sustainable Cities, as one of the eco-architecture models in urban villages by utilizing their respective land and space.Keyword: Eco-Architecture, Eco Village, Green SettlementAbstrak: Desa Bojongsoang sebagai salah satu wilayah di Kecamatan Bojongsoang merupakan kawasan yang padat penduduk, di mana terdapat pergeseran dan pengalih fungsilahan hijau menjadi lahan terbangun (seperti: perumahan baru, industri/pabrik dan lain-lain).

Published: April 2020

Today, the properties of rapeseed oil, affecting the fuel supply processes in a tractor diesel, are density, kinematic and dynamic viscosity, as well as surface tension. The purpose of this research is to expand the limits of the fuel base of tractor diesel engines by using mixed fuels with insufficient low-temperature properties. In this regard, the determination of the optimal composition of mixed fuel for the operation of the fuel supply equipment of tractor diesels is a very urgent task. To solve this problem, theoretical studies were conducted to determine the effect of rapeseed oil additives on the properties of mixed fuels, as well as testing a diesel fuel injector. As a result of the studies, the dependences of the viscosity of the mixed fuel, the pressure of injection beginning, the tightness of the locking cone, and the hydro-density of the spray nozzle on the addition of rapeseed oil with an additive were determined. Based on theoretical calculations, the value of the viscosity of mixed fuel that meets the requirements of the manufacturer's specifications for fuel injectors is obtained. An analysis of the experimental dependences showed that with an increase in the proportion of rapeseed oil in mixed fuel from 0 to 100 %, there increased: the pressure at the beginning of injection from 20,88 to 21,08 MPa, the time until a drop of fuel comes off from the nozzle of the spray from 18 to 104 s, and pressure reduction time decreased from 5,2 to 11,3 s. Tests shown that for all mixed fuel compositions, the injection start pressure, tightness on the locking cone, spray water density and spray needle mobility meet the requirements of GOST 10579-2017, however, the spray quality corresponds to mixed fuel compositions with rapeseed oil up to 60 %. Thus, the use of the proposed fuel compositions will improve the low-temperature properties of mixed fuels with additives of rapeseed oil, and thus expand the fuel base of tractor diesels.
Stabilization of the load mode of the internal combustion engine of the tractor through the use of a hybrid power plant
Authors: Rakov V. A , Litvinov V. I
Published: April 2020

It is known that the main costs in the operation of agricultural machinery are associated with fuels, lubricants and spare parts. The attempts are made to improve the performance of the machinery by reducing operating costs. This happens due to the increasing competitive requirements of the final product. For example, during daily operation of the MTZ-82 tractor, the most widespread tractor in the Eurasian Economic Union, when delivering feed and driving a feeder for a year of operation, just the fuel costs will amount to approximately 20 % of its initial cost (300 thousand Russian rubles). In addition, to ensure the tractor is in a working condition, it will require spare parts and other consumables for another hundreds of thousands of rubles in Russian currency. The diesel engine used in tractors idles most of the time and, as a result, is underloaded. In peak loads, on the contrary, more power is required and, accordingly, it is necessary to create a sufficient energy reserve. This in turn inevitably leads to increased fuel consumption. Hence, there is a need to stabilize the load mode of the engine, reduce its operation in underloaded modes and at maximum loads. This problem can be solved in various ways. One of them is a combination of a diesel engine and an electromechanical transmission. Such power plants are usually called combined or hybrid. Among several typical structural schemes in agricultural machinery, hybrid power plants of the mild hybrid type and full hybrid type were most widely used. The presented methodology will allow to analyze the proposed schemes of a hybrid power plant, assess possible losses and calculate the required engine power, and ultimately determine a more rational scheme for the given operating conditions. The authors also presented the results of a comparative calculation of the required power of an internal combustion engine of hybrid power plants.

Published: April 2020

In grain self-propelled harvesters, when performing technological processes of mowing grain crops and cleaning grain, the oscillating working bodies are used. Having advantages in carrying out technological processes, they are a source of alternating load caused by the inertia forces of the masses of the elements of these organs and leading to the dynamic loading of their drives and vibration of the combine frame. One way to overcome these shortcomings is the recovery of energy in the drives of the working bodies. The authors of the article have proposed a method that, due to the use of a regenerative drive, can reduce its dynamic loading, as well as reduce the vibration of the machinery frame. Based on the proposed method, a method for balancing a single-knife cutting apparatus has been developed. For an experimental assessment of the legitimacy of the theoretical developments underlying the presented technical solution, a prototype drive of oscillating working bodies was developed and manufactured, which allows simulating the operation of traditional and regenerative cutting machine drives. The experimental studies of the prototype model confirmed the validity of the theoretical background of the developed method for balancing a single-knife cutting apparatus and allowed to deepen the theoretical and empirical knowledge in the field of regenerative drives. An analysis of the results of experimental studies of prototype samples showed that, compared with a traditional drive, a regenerative drive can reduce the load and vibration activity by more than 1,5 times. The factors affecting the efficiency of the regenerative drive of a single-knife cutting device have been established, which include: the presence of higher harmonics in the law of motion of the knife provided by the rolling washer mechanism, resonance phenomena in the drive of oscillating masses and structural elements of the header, simplification of the design of the drive of the recuperator counterweight.

Published: April 2020

In the process of operation, the interval coefficient of readiness of technical systems in the agro-industrial complex should correspond to the strategy of trouble-free operation in the interval of time required to perform the required amount of work, or technological operation in the production of agricultural products. Improving and maintaining the reliability of technical systems in the agro-industrial complex is largely determined by the perfection of methods and reliability management system. Currently, a lot of models of reliability management have been developed, which allow to quantify the results of management and purposefully influence these results in the required direction. The issues of reliability management at the stages of design and serial production of technical systems are most fully developed in them and much less - at the stage of their operation. However, the management of the reliability of technical systems at the stage of their operation, which consists in maintaining the level of reliability of the devices provided by the manufacturer, implemented by means of justification, appointment and execution for the available or specified time of the complex of measures for their technical and technological maintenance, is no less important task. The structural scheme of management of reliability of technical systems in agro-industrial complex, including strategic management of reliability, carried out at the stages of design and production of technical systems and operational management of reliability, carried out at the stage of operation of technical systems in the real conditions of agro-industrial enterprises. Introduced the concept of «Functional operational diagnosis» - a complex of measures, directed on increase of reliability of technical systems and their elements due to technology and means of rapid diagnosis, redundant from the point of view of classical domestic strategies of maintenance and repair of machinery, but is necessary to ensure absolute reliability interval. The block diagram of functional operational diagnostics of technical systems in the agro-industrial complex and their elements is developed.
The way to improve the quality of the application of lime fertilizers
Authors: Sedashkin A. N , Kostrigin A. A , Milyushina E. A
Published: April 2020

The article presents some results of comparative tests conducted at the N.P. Ogarev Mordovia State University of the unit when introducing pulverized calcareous fertilizers with serial and experimental centrifugal working body. The influence of the uneven distribution of fertilizers along the width of the capture unit was obtained. The observations showed that upon mechanical spreading (for example, a centrifugal disk) of fertilizers with different particle size characteristics, large particles fly further under the influence of the initial velocity acquired during the falling of the disk, and small (dusty) particles fall on the soil near the center of the disk. Therefore, it is proposed to use a differential feed, both mechanical and pneumatic, for the introduction of ameliorants. Many studies examine in detail the influence of kinetic energy on a fertilizer particle when it leaves the centrifugal working body, and there is insufficient research on the influence of the kinetic energy of an inclined air flow on the additional dispersal of dispersed particles and on the uniformity of their application. To test this hypothesis, the experiments to determine the uneven distribution of fertilizers along the width of the aggregate when introduced by the experimental and serial working body were conducted. For experiments, the base model of the MVU-6 spreader was taken. On this machine, a pneumocentrifugal working body developed by authors was installed in place of the serial working body. As experiments showed, the experimental working body allowed to increase the width of the capture from 6 to 10 m and reduce the uneven distribution of calcareous ameliorants on the total width of the capture from 45,0 to 25,0 %. Overlapping adjacent passages for the experimental setup with half or more of the total working width allows to obtain uniform distribution up to ± 25 %, and an increase in the working speed from 1,5 to 2,0 m/s at a working width of 8 m leads to a deterioration in the uniform distribution of fertilizers on the surface of the field.
Telemedicine and ehealth to empower patients with diabetes mellitus, fostering and enhancing the results of a functional diet
Authors: Cipolla Maurizio , Capello Fabio , Gaddi Antonio V.
Published: April 2020

Functional food is considered to be effective in promoting health and wellbeing. Patients with Type 2 Diabetes Mellitus strongly depend on diet to achieve better glycaemic control and to reduce the burden of the disease. However, adherence to a controlled diet and to proper monitoring of the disease may be challenging for the patients and their family. The use of electronic devices and software together with the implementation of a tailored telemedicine model can help to overcome some of the issues related to the management of this complex disease. To better understand how a telemedicine system can be useful in empowering patients with diabetes so as to enhance the effects of a therapeutic diet, we propose a research protocol as part of the Diabete Calabria 2.0 project, aimed to study a working model in a real-life setting.
A decade of Semantic Web research through the lenses of a mixed methods approach

Published: April 2020

The identification of research topics and trends is an important scientometric activity, as it can help guide the direction of future research. In the Semantic Web area, initially topic and trend detection was primarily performed through qualitative, top-down style approaches, that rely on expert knowledge. More recently, data-driven, bottom-up approaches have been proposed that offer a quantitative analysis of the evolution of a research domain. In this paper, we aim to provide a broader and more complete picture of Semantic Web topics and trends by adopting a mixed methods methodology, which allows for the combined use of both qualitative and quantitative approaches. Concretely, we build on a qualitative analysis of the main seminal papers, which adopt a top-down approach, and on quantitative results derived with three bottom-up data-driven approaches (Rexplore, Saffron, PoolParty), on a corpus of Semantic Web papers published between 2006 and 2015. In this process, we both use the latter for “fact-checking” on the former and also to derive key findings in relation to the strengths and weaknesses of top-down and bottom-up approaches to research topic identification. Although we provide a detailed study on the past decade of Semantic Web research, the findings and the methodology are relevant not only for our community but beyond the area of the Semantic Web to other research fields as well.
