Гликированный гемоглобин: механизмы образования и клиническое значение (обзор литературы и собственные исследования)
Authors: Radchenko O.M. , Korolyuk O.Ya.
Published: May 2020

Уровень гликированного гемоглобина (HbA1c) свидетельствует о содержании в организме конечных продуктов усиленного гликозилирования (advanced glycation end products, AGE), однако на практике необходимость в его определении недооценивается. С целью обсуждения диагностического и прогностического значения HbA1c проведен обзор литературы, проанализованы результаты обследования 116 больных ишемической болезнью серца с детальным анализом метаболизма углеводов, включая проспективное наблюдение за ними на протяжении 40 месяцев. Установлено, что уровень HbA1c свидетельствует о содержании AGE, которые стимулируют продукцию свободных радикалов и окислительную модификацию белков и липидов, уменьшают клеточный транспорт, активируют воспалительные цитокины и хемокины, вызывают иммунные реакции и мутации, повышают активность молекул адгезии и нарушают функцию рецепторов. Обсуждается их роль в патогенезе многих заболеваний — артериальной гипертензии, диабетических сосудистых осложнений, нефропатии, атеросклероза, болезни Альцгеймера, деменции, катаракты, преждевременного старения, потери мышечной массы, плохого заживления ран и злокачественных опухолей и др. По собственным данным, HbA1c является маркером неудовлетворительного метаболического контроля в течение последних трех месяцев, сосудистых осложнений сахарного диабета, коронарной патологии, дислипидемий, инсулинорезистентности, системного воспаления и высокой вероятности возникновения сахарного диабета в ближайшие три года. Этот показатель позволяет дифференцировать острую стрессовою и хроническую гипергликемии. Содержание HbA1c следует контролировать не только у больных сахарным диабетом, но и у лиц пожилого и старческого возраста, курящих, пациентов с атеросклеротическим поражением сосудов и хеликобактерной инфекцией.
La disputa por el Parque Nacional Rapa Nui
Authors: Concha Mathiesen Roberto
Published: May 2020

This paper refers to the dispute process between the Rapanui ethnic group and the National Forestry Corporation (CONAF), for the administration of the Rapa Nui National Park (PNRN), which for decades has been incorporated into the National System of Protected Wildlife Areas of the State. The Rapanui ethnic group assumes as one of its main claims against the State of Chile that the administration of the park be transferred to it, following the example of the lican antai indigenous communities (San Pedro de Atacama, Chile). The actions taken to achieve the transfer of the administration and the results reached by the rapanui part account for the political and economic uses of the Park, as an identity reference and source of income, in a context of increasing differentiation with respect to the State of Chile. The PNRN has various declarations of heritage since it concentrates monumental archeology sites on the island. We analyze the economic use of heritage from the perspective of ethnoeconomics (Comaroff & Comaroff, 2009), and its interaction with the political use of heritage. Our hypothesis is that both uses of the patrimony (economic and political)

This study is done to explore learning difficulties when students are given trig problems in solving math problems. Learning difficulties that encounter during learning and results in less than optimal learning. Trigonometric materials given are just about the number and ratio of sine cosine. Trigonometric materials are given based on the results of a study in student mathematics problem. The ability to solve mathematical problems based on 4 indicators is to understand problems, plan ideas to use, solve problems and reexamine them. This research was tested in praise of the sophomores science class 2 MAN Cimahi. This method of research with qualitative research with students analyzes answer results. The results of this research have found some difficulty with learning problem-solving skills. As for the fourth problem he gave, many of the students had difficulty solving the trigonometry problem.
Mutuality Talk in a Family-Owned Multinational
Authors: Gilbert Paul Robert , Dolan Catherine
Published: May 2020

This article draws on work carried out as part of a collaboration between an elite business school and a family-owned multinational corporation, concerned with promoting ‘mutuality in business’ as a new frontier of responsible capitalism. While the business school partners treated mutuality as a new principle central to an emergent ethical capitalism, the corporation claimed mutuality as a long-established value unique to their company. Both interpretations foreground a central problem in recent writing on the anthropology of business/corporations: the tension between the claim that economic life is always embedded within a moral calculus, and the shift towards increasingly ethical behaviour among many corporations. Further, recent work in the anthropology of business rejects normative evaluations of corporate ethicizing. When corporations lay claim to ethical renewal, but maintain a commitment to competition and growth, then anthropologists must balance a sympathetic engagement with corporate ethicizing, and critical engagement with growth-based strategies.
Erasmus Syllogisms in Cognition and Facilitation of Organizational Innovation
Authors: Bye Rolf Johan , Johansen Stein Erik
Published: May 2020

By use of an empirical example from a planned organizational change program within an international company, we examine how specific characteristics of objects (forms) used to represent ideas –  in interaction with “hard-wired” aspects of human cognition –  may contribute to explain outcomes of translation processes and the extent of alteration of the design of the future organization.  We argue that a type of syllogism judged as invalid by criteria of formal logics – denoted as Erasmus syllogism – could be rather common in reasoning, and that these logically invalid interferences may contribute to significant innovations. Situations where syllogisms are not recognized as invalid by the involved actors seem to be more prevalent when e.g. the actors are unfamiliar with the semantic content (as e.g. abstract symbols). We argue that understanding of semiotic conditions for occurrence of formal logically invalid syllogism, as well as of the neglect of their invalidity by involved actors in ongoing discourses and reasoning, may contribute to a better understanding of how ideas and objects are translated, within organizations as well as in general. The discussion is a contribution to better understanding of why and how ideas are altered as part of ongoing sense making processes within organizations.
Practicing Life Worlds: Theory and Reality in Teaching Design Anthropology Through Entrepreneur Collaboration
Authors: Fabio Mattioli  , Harriette Richards
Published: May 2020

In the contemporary neoliberal university, practice-based learning is increasingly necessary as a means to foster dynamic thinking and bolster student employability. However, for students who feel like customers, this type of ‘messy’ practical experience is difficult to reconcile with their expectations and anxieties about the future. Students who embrace the ‘customer’ education approach expect their learning to be packaged in a manner that practice-based programs are ill-equipped to provide. Based on our qualitative observations teaching a collaborative design anthropology subject at the University of Melbourne, we unpack the various ironies and disconnections between theory and practice around practice-based learning. While experimental, practice-based courses such as ours entail multiple challenges, they are nevertheless worthwhile and necessary, not only for the continued evolution of anthropology but also for our students.
Development of an Integrated Tool for Small-scale Maize Farming in Uganda
Authors: Obura Juma Louis Mahd , Kambugu Robert Kyeyune , Kiggundu Nicholas , Balimunsi Hussein Kivumbi , Kyamanywa Samuel
Published: May 2020

About 62% of the maize produced in developing countries is cultivated manually owing to limited access to appropriate technology. Available technologies perform a single operation, necessitating farmers to buy multiple implements, which is expensive. In this study, an ox-drawn tool integrating a plough, planter and cultivator for small-scale maize farming was developed and its performance evaluated. Planting and cultivating units were designed and fabricated for assembly onto an existing standard ox-plough beam. The integrated tool was tested in the field to assess the effectiveness and efficiency of cultivation and planting of maize. Results showed that the planting unit had an average seed rate of 35.4 kg ha-1 with a seed damage of 4% and an effective field capacity of 0.15 ha h-1 at a field efficiency of 87.3%. The cultivating unit had an effective field capacity of 0.1 ha h-1 and a weeding efficiency of 86%. The efficiency, effectiveness and reliability for field operations are superior to manual operations currently used by farmers and are comparable to single-unit prototypes developed in other countries. This demonstrates the technical feasibility of integrating planting and cultivation units onto an existing mouldboard plough instead of buying multiple tools.
Fresh and Hardened Properties of Styrene Butadiene Rubber (SBR) Modified Concrete
Authors: Qadri Muhammad Ahmed , Hameed Huzaifah , Bhutta Osama
Published: May 2020

The durability of concrete has been studied ever since it was first used. Researchers have incorporated several materials to make concrete strong and durable. This research focuses on the infusion of styrene butadiene rubber polymer (SBR) as a partial replacement of cement and studies its effects on fresh and hardened properties of concrete. Samples were prepared using partial replacement of SBR in proportions of 0%, 5%, 10% and 20%. Results showed that the fresh density of concrete decreased with the addition of SBR whereas the trends of workability showed an increase with cement replacement. Compressive strength increased at lower percentage replacements however the flexural and tensile strength increased till 15% SBR addition after which it decreased. The total porosity in terms of water absorption decreased which makes SBR modified concrete feasible for concretes exposed to moist conditions and the decreased porosity would increase its durability against chloride induced corrosion.

How to Prevent Crowdsourcing Disasters and Leverage Positive Side Effects of Open Innovation
Authors: Füller Johann , Hutter Katja , Kröger Niclas
Published: May 2020

The gains from crowdsourcing can be high, but so can the risks. Contests may become a nightmare for the sponsoring organization if the innovators do not behave as planned. When contest managers act in undesirable ways from a participant’s perspective, community members might bash, shame or ridicule a company. To prevent “firestorms” – negative, often highly emotional posts in social media that are eagerly taken over by traditional media – project sponsors need to ensure fairness throughout the contest. The value of the price and the procedures for selecting winners must be fair and transparent – and companies need to stick to predefined rules. Organizations that succeed in keeping their community motivated might not only benefit from new ideas, but also from additional positive effects. Devoting time, skills and personal engagement to developing new ideas for a company favors intense relationships, and participants often become passionate brand followers. By communicating openly about their approach of open innovation, companies can also foster their innovative image.
¿Qué comen las mujeres trabajadoras en oficinas públicas? Prácticas del comer de mujeres empleadas de la Administración Pública Nacional Argentina
Authors: Boragnio Aldana
Published: May 2020

Objetivo: conocer, de modo exhaustivo, las comidas que consumen las empleadas públicas de la Administración Pública Nacional Argentina, durante la jornada de trabajo y las características principales de los menús. Metodología: la estrategia metodológica utilizada fue cualitativa. Se realizaron entrevistas en profundidad, el muestreo fue de tipo intencional, bajo el procedimiento de “bola de nieve”, y el tamaño fue determinado por la saturación teórica. Resultados: los principales resultados fueron la descripción del menú cotidiano de las mujeres entrevistadas, el cual se organiza entre sándwiches, tartas y ensaladas. Por otro lado, se conoció y profundizó en la relación que se da entre la elección de la comida, sus características y el tiempo/espacio del comer en la oficina. Limitaciones: la investigación se llevó a cabo en una Secretaría de la Administración Pública Nacional Argentina, lo que limita la posibilidad de generalización de los resultados a las empleadas de la Administración Pública y el conocimiento sobre otras oficinas geolocalizadas en otras zonas de la Ciudad de Buenos Aires. Conclusiones: se exponen las comidas que consumen cotidianamente las mujeres trabajadoras de oficina durante la jornada laboral y se sostiene que la oficina, y sus condiciones materiales de espacio/tiempo, serán las condiciones ambientales en las que se darán las prácticas del comer, conformándose una comensalidad descartable como comensalidades específica de oficina pública.
The Constitutional Difference in Canadian Asymmetry
Authors: Ibbetson Heather
Published: May 2020

This paper discusses how asymmetrical Canadian federalism contributes to neo-colonialism and therefore, also the social inequalities faced by Indigenous nations. Asymmetrical federalism has been heralded as a system that maintains a balance of power among the diverse nations that constitute Canada. However, many fail to recognize that Canadian federalism contributes to neo-colonialism, as it validates solely colonizers through the power division in the Constitution Act of 1982. Further, this power imbalance places Indigenous nations under the jurisdiction of the federal government. This greatly limits the ability of Indigenous nations to self-govern and be heard within the Canadian system of government. Through furthering neo-colonial power divisions, the Canadian federal system significantly contributes to social inequalities, such as poor healthcare coverage, faced by Indigenous nations.
Replacing FPTP
Authors: Di Candia Alberto
Published: May 2020

Canada’s use of the First-Past-the-Post electoral system has been defended due to its simplicity, constituency representation, and inherent stability. Arguments have been raised, however, that the system does not sufficiently represent Canadian demographics in parliament, it renders opposition parties ineffective, smaller parties have trouble or are unable to win seats in parliament, and regionally-concentrated parties are encouraged over national based ones. It has been suggested that adding an element of proportionality would address some of these issues. This paper seeks to consider this claim by examining the political outcomes of proportional electoral systems. The literature review outlined that the use of proportional systems increased descriptive as well as geographic representation, and was positively linked to voter turnout.
Tailor-Made for Canada
Authors: McCracken Damian John
Published: May 2020

While reform of Canada's electoral system has not yet occurred, it has been an ever-present, ever-potent topic in Canadian political science since the middle of the 20th Century. While there are aspects of First-Past-the-Post (FPTP) to be admired, its fundamental flaws cannot be ignored; the system encourages parties to exacerbate sectionalism, leaves far too many voters unrepresented, and too often allows for uncooperative governments. Mixed-Member Proportional (MMP), a form of Proportional Representation (PR), possesses the best aspect of FPTP, local representation and accountability, and amends its most serious flaws. MMP represents all votes cast, attenuates sectionalism, and creates diverse legislatures that incentivize cross-party cooperation far more than FPTP does currently. Canada is nearly a perfect country for MMP, and this system should be implemented for our federal elections.
Systemic Lupus Erythematosus associated refractory pancytopenia responding only to intravenous immunoglobulins
Authors: Iqbal Tahir , Baig Wajahat Sultan , Arshad Saamia , Awan Sara Altaf
Published: May 2020

Background:

We, here, describe the case of Systemic Lupus Erythematosus (SLE) with pancytopenia, refractory to steroids, immunosuppressive therapy, and plasmapharesis that ultimately responded to intravenous immunoglobulins (IVIG). To the best of our knowledge, very few cases of this type have been reported in literature.

Case presentation:

A 40-year-old female presented with complaints of hematemesis, hematochezia, gum bleed, epistaxis, menorrhagia, and fever. After careful examination and investigation she was diagnosed with SLE associated with pancytopenia refractory to conventional means of treatment. Pancytopenia responds normally to steroids and immunosuppressive agents in these patients however our patient responded only to IVIG.

Conclusion:

This case report highlights the fact that early use of Intravenous immunoglobulins in patients of SLE with severe and refractory pancytopenia can prevent morbidity and mortality.

Published: May 2020

Artykuł poświęcony jest niektórym aspektom substancji zapachowych pochodzenia roślinnego, stosowanych jednocześnie w przemyśle spożywczym i perfumeryjnym. Od starożytności opracowano wiele technik ekstrakcji w celu uzyskania olejków eterycznych. Niektóre z nich są nadal stosowane. Nowe ekstrakcje, takie jak: mikrofalowe lub ultradźwiękowe, są coraz bardziej popularne i pozwalają zaoszczędzić czas oraz koszty. Niezależnie od procedury powstałe olejki eteryczne są źródłem wielu związków chemicznych, tzw. izolatów. Mogą one być stosowane jako dodatki do żywności lub jako materiały wyjściowe do syntezy organicznej. Niektóre substancje zapachowe występują w bardzo małych ilościach w materiale roślinnym, dlatego ekstrakcja nie jest opłacalna ekonomicznie, ale po ustaleniu ich struktur chemicznych i opracowaniu procedur syntetycznych, w niektórych przypadkach są one pozyskiwane na skalę przemysłową. Substancje opisane poniżej to tylko niewielka część z 2000–3000 pachnących cząsteczek, które sprawiają, że nasze życie jest przyjemniejsze, zarówno w jedzeniu, jak i perfumach.
De olhos abertos, de olhos fechados
Authors: Ragazzi Alexandre
Published: May 2020

A partir de uma imagem que se encontra à venda em muitos centros urbanos brasileiros e que mostra o rosto de um Cristo crucificado ora de olhos abertos, ora de olhos fechados, apresento, neste artigo, uma análise sobre as principais alterações formais ocorridas com esse tipo iconográfico. Ao longo dessa abordagem, procurei compreender as imagens em seus contextos originais de produção, mas não isoladamente, e sim em constante diálogo, seja umas com as outras, seja com o mundo contemporâneo. Assim, foram consideradas as tipologias da cruz sem a presença do Cristo, do Christus triumphans, do Christus patiens, do Christus dolens e do Cristo agonizante, modelos cuja recepção foi avaliada com a intenção de compreender mais profundamente as representações de Bom Jesus de Matosinhos e desse Cristo crucificado que exibe alternadamente os olhos abertos e fechados. Ao final, através de métodos próprios da História da Arte, espero demonstrar como essas imagens sobrepuseram-se e até mesmo se fundiram, sendo recebidas com naturalidade pela maioria dos atuais praticantes do cristianismo.
Anticlassicismo da apropriação de imagem no tempo presente
Authors: Midlej Dilson Rodrigues
Published: May 2020

Procedimento muitas vezes visto pela historiografia da arte como marginal e periférico, a apropriação de imagem tem sido fundamental para artistas contraporem valores entre tempos históricos distintos. O artigo objetiva refletir acerca dos desvios semânticos presentes nas abordagens de produções dos artistas brasileiros Caetano de Almeida, Renato Medeiros, Alex Flemming, Odires Mlászho, Camila Soato e Calasans Neto, que utilizam a apropriação de imagem de obras classiciantes, com ênfase na francesa Orlan. As reflexões originam-se de conteúdos inicialmente abordados em pesquisa de doutoramento, agora ampliados, e utiliza uma combinação dos métodos de análise e síntese, analítico-comparativo e conhecimentos do método histórico. Os artistas enfocados evidenciam olhares críticos e anticlássicos ao contrapor culturas e tradições distintas, em especial em obras classicizantes de Ingres e David. Seus tabalhos resultam em apropriações de imagens de obras-fontes de diversas origens e tempos históricos, constituindo-se em manifestações híbridas que rechaçam valores colonialistas e eurocentristas, e trazem à luz questões pluralistas relevantes do tempo presente. O artigo conclui ser a apropriação de imagem um locus preferencial das expressões da arte contemporânea, por conferir novos e diferenciados significados à arte antiga.

Attempt of Costus arbuscular mycorrhizal inoculants association with leguminous foliage whey on chlorophyll of sunflower (Helianthus annus L.) plants
Authors: Jadhav Rajesh Khanduji , Anil Lodhi
Published: May 2020

Reporters founded that mycorrhizal association in plant kingdom improves the plant growth. The present attempt has been on the use of Mycorrhiza for Helianthus growth in stress condition of the adverse red soil of konkan region, India and other climatic factors. Earlier reporters for the purpose to avoid chemical fertilisers, founded that Deproteinised juice (DPJ) or foliage whey induces appropriate plant growth and enhance soil fertility. During present investigation, mycorrhiza from Costus sp application to soil of potted sunflower plants influence was compared with organic DPJ addition obtained from fenugreek foliage during the process of green crop fractionation (GCF) technique. This whey is randomly disposed during this technology of leaf protein preparation, so appropriate use of it is advised. Whether the mycorrhiza and DPJ combination treatment were feasible for seed germination and the seedling growth of the Helianthus plant, it was analysed and compared with control. Studies were experimented on the effect of mycorrhiza treated alone and DPJ treated alone whether improves the plant growth. DPJ if added with mycorrhiza in soil, showed significant rate of germination. In earlier research, it was elucidated that the DPJ contains phytohormones auxins, gibberellins and cytokinins in unknown quantity which boosts the plant growth comparative to mycorrhizal influence. The chlorophyll content of the DPJ treated plants enhanced as compared with control while the content showed no significant difference with mycorrhiza.

Effect of Partial Dependence of Photopeak Data on The Calculations of NaI(Tl) Detector Spectrum
Authors: Ahmad Elawi Mahmoud , Taha Ahmad Hafsa
Published: May 2020

Partial dependence of photopeak data of ɣ-ray energies is considering apart of peak channels after subtracting background (including Compton distribution) and obtaining symmetric Gaussian distribution, then considering this part to obtain other total data of peak. This was investigated by using NaI(Tl) detector with Eu-152, Ra-226 and Cs-137 point sources. For the isolated peaks of Eu-152, Gaussian shape is obtained, and the areas between ±σ and ±0.5σ were determined and efficiency is obtained. The calculated transformation to total data of peaks gave excellent agreement with the ordinary case. The overlap between the two peaks at 609.3 (Ra-226) and 661.6 keV (Cs-137) is studied with using σ values from data when sources are separated, and counts in peaks centroids. The data of each peak is "restored" and compared with that when sources are separated and gave a 98% agreement. Also the overlap between the two peaks at 1120 and 1238 keV (Ra-226) is studied with adopting the σ values from the shape calibration curve of Eu-152 and centroid counts in the same way as for the Ra-226 and Cs-137 case. The resultant peaks areas are compared with those obtained from efficiency calibration curve of Eu-152. However results here are of lower agreement.

superconductor samples with chemical composition (Hg1-xPbxBa2Ca3-yMgyCu O10+δ) were prepared by solid state reaction method. The effect of partial substitution of Pb and Mg on the structural and electrical properties of this compound were studied. The lattice parameters were characterized by using  X-ray diffraction technique and the results showed that all the samples crystallize in tetragonal crystal structure. This technique proved increase in value of lattice constant (c) with increasing in Pb concentration until 0.4 when y= 0 and decreased after this concentration. On the other hand the partial substitution of Mg in Ca showed decreasing in the value of (c) with increasing Mg concentration to (0.2,0.4,0.8,1,1.4,1.6) when the Pb is constant at (0.4), but the value of (c) increased with increasing Mg to (0.6,1.2). Standard four-probe method used in electrical resistivity measurements and the measurements showed an improvement in Tc from (0.1-0.4) and after this concentration Tc value decreased at substitution of Pb in Hg when Mg=0, where the critical temperature increases from 121K to 134K with an increase of  x from 0 to 0.4 and decreases after this concentration to 120K , but for substitution of Mg in Ca the Tc is increased to 135K,136K,139K,142K and 145K with increasing of Mg to (0.2,0.4,0.8,1,1.4) and decreased to 134K,140K and 140K with  increasing concentration of Mg to (0.6,1.2,1.6) while Pb is constant at (0.4). The surface has been investigated by using scanning electron microscope (SEM) and atomic force microscopy (AFM). These tests were shown that all specimens which tested have good crystalline and homogeneous surface .

Authors: Hammood Maytham
Published: May 2020

The huge development in the websites and continuous exchange of the information led to more consideration of the websites accessibility. There are many accessibility-based on studies conducted throughout the world. However, the existing literature lacks a study on the assessment of accessibility to the Iraqi universities websites. Accordingly, this study measured the accessibility to websites of 36 Iraqi public universities listed in the official webpage of the Iraqi Ministry of Higher Education. Furthermore, it explored the relationships among three free web accessibility tools, namely Web Accessibility Versatile Evaluator, EIII Page Checker and Access Monitor, to test their agreement in terms of the accessibility results. These three free tools were used to evaluate the accessibility of the Iraqi universities websites. Statistical Package for the Social Sciences was used to analyze the results. The results of the three tools showed that the issue of accessibility is ignored by the webmasters of websites under the study. In addition, this study presented agreement among the three tools in terms of results.

Current and prospective business characteristics enter the market climate. So today we live in four eras at the same time, the globalization of the economic period, the period of information technology, the strategic efficiency management era, and the revolutionary era in management. We must discover the characteristics of each period and bring it against management principles. Based on the results of the assessment, it is known that Kademangan Village not only has abundant natural potential, but is also supported by skilled Human Resources (HR), especially in handicrafts and food preparations. Even so the living conditions of the people, especially the economic aspects, are not sufficient. This is caused by several factors such as the still poor quality of human resources and inadequate village infrastructure. For example, the community of handicrafts and food preparations have not been able to produce different products and of good quality so that they have high selling points. Considering these various conditions, the PKM (Student Activity Center) activities are directed at the economic aspect by organizing training for community service activities with the theme "Entrepreneurship Training to Improve Community Economy in Kademangan Village, Mojoagung District, Jombang Regency". Keywords: Economy; Entrepreneurship; Society
