Experimental Study of Bond Strength between Existing Roof Slab and Concrete Support of Flat Roof Mounted Solar Arrays
Authors:   Department of Civil Engineering, Z.H.C.E.T., A.M.U., Aligarh–202002, India, Agarwal Ashish , Irtaza Hassan
Published: March 2021

Rooftop mounted solar array systems are connected to the existing concrete roof using casting concrete blocks over the existing concrete roof surface or by using precast concrete blocks. Since fixing the mounting system directly on the roof surface using a bolted connection is not advisable since it can affect roof strength, concrete blocks, either precast or cast in situ, are desirable to support the mounting system. To better understand the bonding mechanism at the interface between old and new concrete surfaces, overlaid specimens were fabricated to measure the various bond strengths. Three different bonding methods, which include cement slurry, casting over existing concrete, and epoxy, were used. The tests performed found that epoxy bonding provides better bond strength for new and existing concrete. To withstand wind loads, the foundation of the solar system should resist horizontal drag and vertical lift forces safely. Self-weight of supporting concrete blocks significantly reduces drag and lift forces coming over the solar system due to wind loads. The bonding strength between the existing concrete roof surface and array supporting concrete blocks also plays a vital role in resisting drag and lift forces. Since the weight of concrete blocks cannot exceed the design load for the roof, drag and lift forces can be resisted by increasing bond strength either by increasing the surface area of blocks (which would increase weight thus may defy purpose) or by using a superior bonding agent.

"Advance design and day to day up-gradation of communication system is the requirement of international telecommunication. The optical communication systems involve the effective fiber coupling or splicing to meet the need of long communication channel. When the studies on both the intensive and extensive properties of optical fiber are exploring new research horizons, the effectiveness of such systems can be calibrated with transmission parameters like transmitted fractional power, which is a function of ‘spot size’ as well. Our study of fiber junctions based on fundamental parameters like wavelength, fiber profile index etc. has touched some unrevealed areas and explored some interesting results. The profile index of optical fiber has received less attention compared to other structural parameters of optical fiber but our study at important wavelengths for different profiles has shown that the less-used fiber profiles has some interesting premier outcomes, which can introduce some significant impact on optical fiber based system design and engineering. We have observed almost frequency or wavelength independent transmitted fractional power around the most used 1.55 micrometer wavelengths at some rarely used fiber profile index. Our study predicts the best and worst fiber profiles for transmitted fractional power (T ), at the same time, we have observed the fiber profile index independent region for a band of ‘T’ values. The reporting and its approach are found to be premier in this field. So, our work is reporting a comparison of effective fiber-to-fiber coupling, based on fiber profile index of different fibers. It is also giving a clear view of the wavelength dependency of effective fiber coupling for different fibers having wide range of graded fiber profiles."

Published: March 2021

The piezo-viscous effect is crucial in fluid flows under high-pressure applications such as fluid film lubrication, microfluidics, and geophysics. We have investigated the combined influences of piezo-viscous dependence and non-Newtonian couple stresses on the performance of circular plate squeeze film bearings using Stokes Micro-Continuum theory of couple stress fluids together with the exponential variation of viscosity with pressure. A closed-form solution for film pressure has been obtained using the homotopy analysis method. The numerical results for pressure and load capacity with different values of the viscosity-pressure parameter have been calculated and compared with iso-viscous couple stress and Newtonian lubricants. An enhanced pressure and load capacity are observed in the analysis. The response time for the bearing (plate approach time) has also been calculated and a significant increase is observed.

Published: March 2021

Shebel Berenta district is one of the highland areas of Ethiopia highly prone to land degradation and drought by the report of the UN Office for the Coordination of Humanitarian Affairs, (OCHA). Assessment of community participation to combat land degradation was the main objective of this study. Mixed research approach with concurrent triangulation design was followed. The target kebeles and the number of respondents were selected purposively. The sample size was found to be 368, which was determined by the Yemaneh (1967) formula and addressed through geographical listing method. Primary data was collected through Questionnaire, interview and FGD; whereas secondary data was also gained from researches, reports and different documents. The quantitative data was analyzed descriptively, and the qualitative data was analyzed using thematic analysis. The result shows that the trend of community participation is found to be decreasing/passive and dominated by the top down or planner centered approach of community participation as it was supported by 72.4% and 86.3% out of 149 and 219 total respondents from vulnerable and less vulnerable kebeles respectively. Incentives to inspire community participation are low and not adequate and resulted in the lack of willingness of the community. Lack of awareness, expansion of open grazing lands, lack of commitment from the people and government side, lack of consistency of Sustainable Land Management Practices (SLM), geographical barriers and others are the observed challenges of CP in the area.

The Unidirectionality of Grammaticalization in Modern Linguistics
Authors: Novospasskaya Natalia V. , Avagyan Asmik A.
Published: March 2021

The present article contains the results of study on unidirectionality of grammaticalization which is understood as a shift from lexical to grammatical signs. The research aims to find out and describe present approaches to the unidirectionality idea and identify the current tendency in attitudes towards this property of grammaticalization. The research methodology includes a content analysis of approaches to the unidirectionality issue, their generalization and analysis of some units questioning the unidirectionality of grammaticalization. The relevance of grammaticalization studies is due to a growing interest of Russian and foreign linguists in grammatical changes, current differences in identifying the main properties of such change as grammaticalization and terminological variation. The theoretical framework of this study is based on the research by T. Givn, Ch. Lehmann, T. Lindstrm, E. Traugott, B. Heine and other famous linguists working in the field of grammaticalization. It is noted that the issue of unidirectionality of grammaticalization is almost ignored in Russian linguistics where unidirectionality is often seen as an integral property of this process. The study results have shown the tendency to accepting the unidirectionality idea and a controversial nature of some examples used to overturn this idea. Such examples include English infinitival to , the verb to dare and the suffix -ish . It has been established that the terms degrammaticalization and lexicalization used to refer to processes opposite to grammaticalization can be considered reasonable depending on their understanding and the meaning of the term grammaticalization. This study is a part of a more extensive research aimed to describe and analyze the mechanisms of grammaticalization in Germanic languages.
System-synergetic approach to studying the essence of state power
Authors: Zyrianov Aleksey V.
Published: March 2021

This article is devoted to the problem of cognition and understanding of the essence of state power. Actualization is carried out by searching for a new paradigm approach in order to determine the fundamental principles that are correlated with the idea to optimize and increase the efficiency of the corresponding sphere of public relations. Acting as an alternative to the substantial and relativistic approach to the study of state power, the system-synergetic approach analyzes the phenomenon of power based on the definition of system, within which the functions of communication and regulation of public relations are assigned to power. As a result, power is seen as a property or function of a social, in particular, political system, the need for which is determined by the presence of society itself and the task of maintaining its integrity. The analysis allows stating that in most modern concepts there is a consistent rejection of the traditional interpretation of power as the result of subject-object relations, where the subject of power is an active, energetic principle, and the object undergoes impact. In contrast to the position of traditionalism, there is a tendency to interpret power as a complex polysystem permeating the entire social structure of society. As a structural and synergistic effect of the system, power is not a property of its individual element, since each element must certainly be correlated with other units of the given system. Power is an intrasystem relatedness of all elements. As a structural principle, power is realized on the basis of equivalent exchange, which means not the equivalence of the exchanged elements, but a situation in which one element is unconceivable without the other, i.e. one element exists in relation to the other, and co-develops with it. Thus, power really fulfills the function of streamlining socio-political ties, making their separation and differentiation expedient. Power, therefore, is the beginning, creating structures, increasing heterogeneities in a continuous social environment and connecting them together. Such a view allows interpreting power as a principle of functioning of the state system: if the state system, with the help of some value proposition, manages to reproduce the corresponding content of consciousness, then it functions quite stably.

Published: March 2021

The aim of this work is to study the etiological and epidemiological features of infectious hemocolites (IG) in hospitalized children of different ages.

Materials and methods of research. An analysis of the results of a survey of 3103 children admitted to hospital treatment for acute intestinal infections (AII) from January to December 2018, among which patients with IG were identified. The etiology of the disease was determined based on the results of the bacteriological method, PCR studies of faeces with Amplicens ® OKI screen-FL reagents, serological and immunological methods. Microscopic examination of faeces was performed to identify protozoa. Patients were divided into age groups: infant (n=78; 30%); early (n=74; 28,5%); preschool (n=63; 24,2%), school (n=45; 17,3%).

Results. The incidence of IG in hospitalized children with AII was 8,4%. Bacterial pathogens of IG were detected in 66,5% of children, IG of unspecified etiology was diagnosed in 24,2%. Viral and bacterial infections were rarely detected (9,2%). Among intestinal viruses, rotavirus (37,5%), norovirus (29,2%) and enterovirus (20,8%) were more frequently detected in hemocolitis of combined viral and bacterial etiology. In the IG age structure, infants (30%), young children (28,5%) and pre-school children (24,2%) made up the majority. The maximum number of IG patients was detected in the summer (10,9% of all cases of AII). Salmonellosis was more often detected in autumn (31,6%), campylobacteriosis – in summer (17.9%) and autumn (24,1%), escherichiosis and shigellosis – in summer (11,5% and 6,4%, respectively). The maximum detection of IG in infants was observed in June (14,1%) and October (12,8%), in young children – in July (17,6%), in preschoolers – in June (12,7%) and November (15,9%), in schoolchildren in May (13,3% of cases) and in October (15,6%).

Conclusion. The incidence of infectious hemocolites in hospitalized children with acute intestinal infections was 8,4%. The bacterial etiology of the disease was detected in 66,5% of children. The age structure of the IG was dominated by children of infant, early and preschool age. The maximum detection of patients with IG was observed in the summer.

The most advanced technology for growing fruit crops, both stone and pome, today is intensive gardening. If the intensive garden is properly organized, its economic efficiency may be several times higher than in the case of traditional technologies, which are not very efficient in modern conditions. This is especially noticeable in the zone of risky farming, where climate and other factors that negatively affect the yield of garden crops make them not attractive from an economic point of view. This is partly why a number of regions have seen a reduction in farmland used for orchards. Bookmark of gardens of intensive type in many respects solves this problem.

Presidentes y orquestadores: la gobernanza de la pandemia de Covid-19 en las Américas
Authors: Legler Thomas
Published: March 2021

Este artículo se propone analizar tendencias contradictorias en la gobernanza hemisférica y regional de la pandemia de Covid-19. Basado en un extenso ejercicio de mapeo de las dinámicas institucionales de cooperación, en él se describe una mezcla de tendencias de gobernanza conflictivas, tanto negativas como positivas, así como desarticuladas y colaborativas. El autor sostiene que la gobernanza de la pandemia en el hemisferio surge de la convergencia histórica y de la vinculación de dos pautas de gobernanza en la seguridad sanitaria, en las últimas décadas: el interpresidencialismo y la orquestación de las organizaciones regionales. A pesar de la impresión de que las respuestas fueron nacionales e individualizadas y de que resaltaron las disfuncionalidades de los esquemas de gobernanza existentes, observamos una efervescencia de formas heterogéneas de cooperación y creación de instituciones hemisféricas y regionales contra el virus y sus consecuencias más amplias. Gracias a su capacidad de resistencia y organización, varios organismos regionales formales y bancos de desarrollo lograron compensar al menos parcialmente las pautas perturbadoras del interpresidencialismo patológico a través de sus funciones como orquestadores de gobernanza. Sobre la base de sus hallazgos, en el artículo se hace un llamado al intercambio fecundo de ideas entre el regionalismo comparativo, el institucionalismo neoliberal y los estudios de gobernanza global, así como la construcción de un interpresidencialismo en red para contrarrestar los peores impulsos de los jefes de estado y de gobierno.

Authors: Parlagreco Elena , Persano Irene , Salvia Anna La , Pia Anna , Scagliotti Giorgio Vittorio , Brizzi Maria Pia
Published: March 2021

Background:

Glucagonoma is a rare functional pancreatic neuroendocrine tumor. Necrolytic migratory erythema (NME) is a paraneoplastic manifestation of glucagonoma and is often the first presenting symptom. The misdiagnosis of this rare entity can affect the patient’s quality of life and his life expectancy.

Case Presentation:

We report a case of a 48-year-old man presenting with pruritic scaly rash, ulcerated skin lesions, and periorbital edema, who was diagnosed and treated for atopic eczema for a 7-year period. Despite treatment, his dermatitis and general conditions progressively worsened, until he was admitted to the emergency department due to weight loss and fatigue. An uncontrolled diabetes was found and the computer tomography scan of the abdomen revealed a tumor located in the tail of the pancreas with liver metastases. Subsequently, liver biopsy and high levels of glucagon confirmed the diagnosis of glucagonoma. The patient was treated with short-acting subcutaneous octreotide for 2 weeks and then with intramuscular slow-release octreotide every 28 days, with a significant improvement of the symptoms.

Conclusion:

This case provides further knowledge about NME, since a timely recognition and treatment of this misleading disease can prevent morbidity from the dermatitis and mortality from the malignancy itself.

Published: March 2021

Background:

Craniofacial teratoma is a rare congenital malformation. We present a case of an intracranial expanding orofacial teratoma, where pathological examination revealed the findings of remarkable ultrasonographic signs and magnetic resonance imaging (MRI).

Case Presentation:

In the 23-week ultrasound examination, a solid cystic mass lesion was revealed in the craniofacial region. MRI showed that the mass had an intracranial extension and spread to the fetal face, and also revealed a marked nasopharyngeal obstruction by the mass. There was a growing tumor protruding from the fetus’s mouth. Slight polyhydramnios was also detected.

Conclusion:

In detecting prenatal anomaly, although the ultrasound is the first scan method applied, MRI in prenatal diagnosis is very useful for evaluating the extent, nasopharyngeal obstruction degree, and extension into the intracranial region of craniofacial teratoma.
