Authors: Doan S.I. , Malysh N.G.
Published: December 2017

Тяжесть инфекционного процесса при острых кишечных инфекциях в современных условиях в Украине изучалась согласно официальным статистическим отчетам Министерства здравоохранения Украины с использованием описательных и аналитических методов эпидемиологических исследований. Установлено, что эпидемиологическая ситуация по заболеваемости острыми кишечными инфекциями неблагоприятна. Самые высокие показатели были зарегистрированы на административных территориях, прилегающих к Черному и Азовскому морям, а также в Харьковской области. В нозологической структуре преобладают острые кишечные инфекции неизвестной этиологии и те из них, которые вызваны вирусами и условно-патогенными микроорганизмами. Эпидемиологическая ситуация по острым кишечным инфекциям осложняется вспышками, чаще всего вызываемыми сальмонеллой и возникающими на предприятиях общественного питания.

Mycobacterium bovis induce una respuesta inmune celular heterogénea en bovinos infectados naturalmente
Authors: Sánchez López Ariel Deliler , Flores Villalva Susana , Gutiérrez Pabello José Ángel
Published: December 2017

Los macrófagos son considerados uno de los principales mecanismos de resistencia a las infecciones micobacterianas. Además, datos experimentales y clínicos indican que el IFN-γ es esencial para la defensa contra Mycobacterium tuberculosis. El objetivo de este estudio fue identificar la capacidad de los macrófagos para controlar el crecimiento intracelular de Mycobacterium bovis y su relación con la producción de IFN-γ en ganado naturalmente infectado con M. bovis. Se evaluó la capacidad de los macrófagos derivados de monocitos obtenidos de sangre periférica de bovinos naturalmente infectados. Además, se midió la producción de IFN-γ producida en respuesta al Derivado proteico purificado bovino (PPDB por sus siglas en inglés) y coctel proteico ESAT-6+CFP-10. Los resultados muestran una variación en la susceptibilidad a M. bovis de los bovinos estudiados. Se observó un rango de porcentaje de sobrevivencia de M. bovis BCG del 80 a 150 % en macrófagos provenientes de bovinos naturalmente infectados, mientras que la producción de IFN-γ hacia el PPDB y coctel proteico fue de 2.5 y 2.0 índice de densidad óptica, respectivamente.  Aunque los datos no demostraron una correlación entre la susceptibilidad del hospedador a M. bovis y la producción de IFN-γ en bovinos naturalmente infectados con este patógeno, no se descarta la hipótesis de que las limitaciones en el funcionamiento de los macrófagos y los linfocitos T desempeñan un papel muy importante en la diseminación de la enfermedad.

Published: December 2017

En el presente estudio se determinó la prevalencia de endometritis subclínica y su efecto en la tasa de gestación en vacas lecheras en manejo intensivo. Entre los días 35 y 45 posparto se seleccionaron 237 vacas sin patologías uterinas (vacas con útero involucionado y sin secreciones vaginales anormales); a todas ellas se les tomó una muestra citológica de endometrio mediante la técnica de Cytobrush. Los frotis se procesaron con la tinción de Diff-Quick. Se contaron un total de 200 células y se determinó la proporción de células polimorfo nucleares (PMN). Las vacas con ≥ 6 % de PMN se consideraron con endometritis subclínica. Cuarenta y tres por ciento (103/237) de las vacas presentó endometritis subclínica. Las vacas con puerperio patológico tuvieron mayor probabilidad de padecer endometritis subclínica que las vacas con puerperio normal (60 vs 36 %, respectivamente; razón de probabilidad= 2.69). Las vacas normales tuvieron mayor tasa de gestación en el primer servicio que la vacas con endometritis subclínica (31.4 vs 20.0 %; respectivamente; razón de probabilidad= 2.02) y la proporción de vacas gestantes en el día 120 posparto fue mayor en las vacas normales que en las vacas con endometritis subclínica (51.6 vs 37.9 %, respectivamente; razón de probabilidad= 1.98). Se concluye que la prevalencia de endometritis subclínica en vacas lecheras entre los días 35 y 45 posparto es de 43 %, lo cual disminuyó en un 11.4 % la tasa de gestación en el primer servicio y en un 13.7 % la tasa de gestación acumulada en el día 120 posparto.

Incidence of middle ear barotrauma in staged versus linear chamber compression during hyperbaric oxygen therapy: a double blinded, randomized controlled trial
Authors:   Anaesthesia – Armed Forces Hospital Lumut, RMN Base, Lumut, Perak 32100 Malaysia, Ng Andrew Wei Aun , Muller Reinhold , Orton John
Published: December 2017

Context: Middle ear barotrauma (MEB) is common during chamber compression in hyperbaric oxygen therapy. However, little evidence exists on an optimal compression protocol to minimize the incidence and severity of MEB. Objective: To compare the incidence of MEB during hyperbaric oxygen therapy using two different chamber compression protocols. Design: Double-blinded, randomized controlled trial. Setting: Hyperbaric Medicine Unit, The Townsville Hospital, Queensland, Australia, September 2012 to December 2014. Patients: 100 participants undergoing their first hyperbaric oxygen therapy session. Intervention: Random assignment to a staged (n=50) or a linear (n=50) compression protocols. Photographs of tympanic membranes were taken pre- and post-treatment and then graded. Middle ear barotrauma was defined as an increase of at least one grade on a modified TEED scale. Results: The observed MEB incidence under the staged protocol was 48% compared to 62% using the linear protocol (P=0.12, exact one-sided binomial test), and thus the staged protocol did not show a significant improvement in MEB. However, the staged protocol resulted in significantly less severe deteriorations in MEB grades when compared to the linear protocol (P=0.028, exact one-sided Mann-Whitney type test). Conclusion: The use of the assessed staged compression protocol for the first hyperbaric oxygen treatment showed no significant effect on the overall incidence of MEB when compared to the gold standard linear protocol but resulted in a significant improvement in the severity of the experienced MEBs. Further studies are needed to elucidate an optimal compression protocol to minimize middle ear barotrauma.

Introduction: Acute carbon monoxide (CO) poisoning causes serious health problems such as neuropsychological sequelae. This study aimed to investigate neuronal apoptosis and the effects of hyperbaric oxygen (HBO2) on different regions of the rat hippocampus after CO poisoning. Methods: 90 mature male Sprague Dawley rats were randomly divided into three groups: the normal control group (NC group), the acute carbon monoxide-poisoned group (CO group) and the hyperbaric oxygen treatment group (HBO2 group). CO exposure included 0, 1, 3, 7, 14 and 21 treatment days, one exposure on the first day, and sacrifice on each of the following days. HBO2 exposure included treatment for 0, 1, 3, 7, 14 and 21 days, daily treatment after CO exposure, and sacrifice after the last HBO2 treatment on each of those days. Hematoxylin-eosin staining, immunohistochemical staining, immunofluorescence staining, and western blot analysis were performed to detect apoptosis in brain tissue samples. Results: MMP-9 and caspase-3 were prominently increased by CO exposure and inhibited by HBO2 in the CA3 region in the hippocampus at one, three and seven days (immunohistochemical staining [IHC]: P < 0.05). Neu N and the ratio of Bcl-2/ BAX were prominently decreased by CO exposure and rescued by HBO2 in the CA3 region after seven days of treatment (IHC: P < 0.05). Conclusion: These findings indicated that neuronal apoptosis in the rat hippocampus could be induced by acute CO exposure, especially in the CA3 region. HBO2 could effectively inhibit neuronal apoptosis, especially in the CA3 region after seven days of treatment. The application of HBO2 to inhibit MMP-9 and apoptosis may contribute to brain recovery after acute CO poisoning.

A neoprene wetsuit is widely used to reduce thermal dispersion during diving. Recent observations have pointed out that elastic recoil of the wetsuit might have significant compressive effects, able to affect water and electrolyte homeostasis during both dry and immersed conditions. The aim of this study was to evaluate the possible cardiovascular and respiratory effects of the neoprene wetsuit in dry conditions in a sample of experienced divers. Twenty-four (24) healthy divers were evaluated by Doppler-echocardiography and by spirometry in basal conditions and while wearing a full neoprene wetsuit. During wetsuit conditions, we observed a significant decrease in heart rate (-5%; p<0.05) and cardiac output (-12%; p<0.05), and a significant increase in total peripheral resistances (15%; p<0.05). Moreover, a significant reduction of right ventricular early diastolic filling was observed (-15%; p<0.05). As concerns pulmonary function, a significant reduction of vital capacity (-2%; p<0.001) and expiratory reserve volume (-25%; p<0.001), and a significant increase of inspiratory capacity (9%; p<0.001) and tidal volume (25%; p<0.05) were observed. These data support the hypothesis that neoprene elastic recoil, possibly due to a compression exerted on chest, might affect systemic circulation (decreasing cardiac output and impairing right ventricular filling) and respiratory function.
Can amputation be prevented in diabetic foot? Interdisciplinary approach to diabetic foot: a case report
Authors:   Harran University, Faculty of Medicine, Sanliurfa, Turkey, Gunes Ali Erdal , Cimsit Maide ,   Istanbul University, Istanbul Medical Faculty, Istanbul, Turkey
Published: December 2017

Diabetic foot ulcers may result in loss of an extremity and may even lead to mortality. The use of comprehensive foot care programs which include early screening and evaluation of problems, foot care education, preventive therapy and referral to specialists has been shown to reduce amputation rates by 49-85. A 51-year-old woman with Type 2 diabetes under surveillance for nine months was referred from the emergency department. She presented with an entirely inflamed right foot with ulcer covering two-thirds proximal of the foot for 30 days’ duration. There was extensive edema as well as cellulitis extending to the knee, fluctuating abscesses and lymphangitis to the ankle. Magnetic resonance imaging showed extensive abscesses and edema in foot compartments. After a further four weeks of antibiotics, 80 sessions of hyperbaric oxygen therapy shrank the wound from 15x15x2 cm to 3x3x0.2 cm. The wound was closed with a split thickness graft, and healing completed four months after presentation. Patients with diabetic foot deserve clinical evaluations of the whole body rather than a regional treatment. An interdisciplinary approach involving both medical and surgical treatment options should be conducted according to this perspective. It could be effective in lowering major amputation rates and even preventing amputations. Simultaneously administered effective debridement methods, utilization of minor amputations for necrotic tissue and lowering the infectious load with appropriate antibiotics, aggressive wound care with the appropriate wound care products, unconventional treatment methods like hyperbaric oxygen treatment and negative pressure wound care may help reduce amputation levels and save extremities.

Published: December 2017

This paper aims at providing a theoretical analysis of the existing research on corporate competition and sustainability risks that occur when companies aspire to reach maximum competitive advantages and gain competitive benefits compared to their rivals. Competitiveness has been described as a multidimensional, theoretical and relative concept linked with the market mechanism. The concept of competitiveness may refer to different levels of aggregation: national, regional, industrial and individual companies. This paper contributes to the theoretical research on corporate competitiveness by the analysis of old and new definitions of this category. It also notes that the sustainability risks connected to competition can be divided into several groups where the authors highlight environmental, legal, financial risks, behaviour risks and state-related risks as the most crucial ones. For companies to be fit for the competitive challenge, the paper identifies main characteristics of such risks and gives policy guidance for their avoidance.

Numerical study of magnetohydrodynamic mixed convective flow in a lid-driven enclosure filled with nanofluid saturated porous medium with center heater
Authors: Mahalakshmi Thangavelu , Nithyadevi Nagarajan , Oztop Hakan
Published: December 2017

This present numerical study explores the MHD mixed convective flow and heat transfer analysis in a square porous enclosure filled with nanofluid having center thin heater. The left and right walls of the enclosure are maintained at temperature T . The bottom wall is c considered with a constant heat source whereas the remaining part of bottom wall and top wall are kept adiabatic. The finite volume method based on SIMPLE algorithm is used to solve the governing equations in order to investigate the effect of heater length, Hartmann, Richardson, and Darcy numbers on the fluid-flow and heat transfer characteristics inside the enclosure. A set of graphical results are presented in terms of streamlines, isotherms, mid height velocity profiles and average Nusselt numbers. The results reveal that heat transfer rate increases as heater length increases for increasing Darcy and Richardson numbers. Among the two positions of heaters, larger enhancement of heat transfer is obtained for horizontal heater of maximum length. It is observed that, Hartmann number is a good control parameter for heat transfer in fluid-flow through porous medium in enclosure. Moreover, Ag-water nanofluid has greater merit to be used for heat transfer enhancement. This problem may be occurred in designing cooling system for electronic equipment to maximize the efficiency with active and secured operational conditions.
Ultrathin Monolithic Zirconia Veneers: Reality or Future? Report of a Clinical Case and One-year Follow-up
Authors: Souza R , Barbosa F , Araújo G , Miyashita E , Bottino MA , Melo R , Zhang Y
Published: December 2017

Yttria-stabilized polycrystalline zirconia ceramics have greatly advanced over the past few years. High-translucent zirconia is a newly introduced ceramic that affords high strength and esthetics and that has significantly increased the clinical indications of monolithic zirconia restorations. Thus, the purpose of this case report was to evaluate the performance of ultrathin monolithic zirconia veneers adhesively luted to enamel surfaces after minimally invasive preparations; in addition, we aimed at presenting a clinical protocol for zirconia surface treatment in order to promote bonding effectiveness to resin cement. This type of restoration presented very acceptable esthetic results and decreased the risk of fracturing the veneer during try-in and clinical use. The results were still satisfactory after one-year follow-up. However, randomized, prospective, controlled clinical trials are required to determine the long-term clinical durability of this treatment.
Real-time Light Transmittance Monitoring for Determining Polymerization Completeness of Conventional and Bulk Fill Dental Composites
Authors: Par M , Repusic I , Skenderovic H , Sever E Klaric , Marovic D , Tarle Z
Published: December 2017

Objectives:

To monitor the real-time changes in light transmittance during composite curing and to use transmittance data to determine the curing times required for a complete polymerization.

Methods:

Three conventional and three bulk fill composites were cured with two light-emitting diode curing units at layer thicknesses of 2 mm and 4 mm. The real-time light transmittance data were collected by a UV-Vis spectrometer in the wavelength range of 350-550 nm, plotted against time (t) and fitted to an exponential function f(t), whose first derivative ΔT(t) = df(t)/dt represented the rate of transmittance change. As the changing transmittance reflects structural changes that occur during polymerization, ΔT(t) > 0 was considered to indicate an ongoing polymerization, whereas ΔT(t) values approaching zero suggested a complete polymerization. This principle was used to determine times required for a complete polymerization (tcomplete) for each material/thickness/curing unit combination.

Results:

Light transmittance was significantly influenced by the material type, sample thickness, and curing unit, amounting to 2.9%-27.0% for the bulk fill and 0.7%-16.7% for the conventional composites. The values of tcomplete amounted to 15.3-23.3 seconds for the bulk fill composites at 2 mm, 20.2-33.3 seconds for the conventional composites at 2 mm, 26.9-42.1 seconds for the bulk fill composites at 4 mm, and 40.1-59.8 seconds for the conventional composites at 4 mm. Additionally, an exponential relationship was discovered between the light transmittance and tcomplete.

Conclusions:

Some of the tcomplete values considerably exceeded the curing times recommended by the manufacturers.

Islam as a mode of belief of the Arab peoples existed for several centuries in its original reign of the Near East. But as soon as it had a vigorous expansion, it turned to the "black countries" on the paths of Africa, first North, then South. In its desire to extend to the whole Africa, the conquering march of Islam was not smooth, it experienced many obstacles and wars. The islamization of the world took place because of many wars, but those wars did not always end with the victory of the Muslims, they sometimes led to the decline of the project of Islamization of the whole world.
EXTERIORISATION OF INTESTINAL STOMA AS A RESULT OF INTESTINAL CANCER DISEASE
Authors: Chrostkowska Iwona , Wanot Bartosz , Biskupek-Wanot Agnieszka , Matulnikova Liudmila
Published: December 2017

Among diseases of the 21st century, intestinal tumours are frequently mentioned. Colon cancer is a serious and growing health problem not only in Poland, but also in the world. As the most common result of fighting for one's own health and often even life is the consent to the intestinal stoma. Intestinal stoma is made by exteriorisation of the preserved intestinal end by abdominal incision outside the abdominal cavity, the incision of the mucous membrane and suturing it to the skin. The three main groups of indications for exteriorisation of stoma are: (a) inflammatory disease of intestines, (b) colitis, rectal and colonic trauma, (c) colorectal cancer. Properly exteriorised stoma on the large intestine should be located on the smooth surface of the skin away from the navel, hip bone, skin folds, scars and also at least 4 cm away from the main surgical cut. Patients should see the fistula well because it is the basis of proper self-care. Dermatological complications are the most common complication of stoma and occur in nearly 80% of patients. It comes to them as a result of irritation of the skin by the intestinal contents that come out of it and causes inflammation. This is usually the result of incorrect stoma care or improper use of stoma equipment. Despite medical advances towards minimizing invasive procedures and limiting the severity of the disease, the problem of the great stress experienced by every person undergoing surgical treatment is still valid and relevant to the outcome of the whole therapy. Choosing intestinal stoma is one of the most stressful treatments, so in this case, not only medical care but also psychological over the patient seems to be a priority.

Las similitudes encontradas entre los resultados del diagnóstico del riesgo y de las percepciones sobre el mismo plantean un escenario propicio para el diseño consensuado de acciones de gestión de la problemática.
La territorialidad campesina indígena y la disputa por el territorio en el Chaco
Authors: Colla Julia Lucía
Published: December 2017

El objetivo de este artículo es comprender la disputa por el territorio que mantienen los campesinos indígenas frente al capital en la provincia de Chaco (Argentina). Para ello, se reflexiona sobre la construcción de la territorialidad de estos sujetos y el papel que han ocupado en la expansión del desarrollo capitalista. Se trabaja con la comunidad del pueblo Qom que habita en los parajes rurales cercanos a la localidad de Pampa del indio, ya que allí se conformaron relaciones sociales distintas respecto a otros espacios geográficos y en cuanto a la vinculación entre indígenas, capital y territorio.                                                      

El abordaje de la investigación es cualitativo, por lo que se ha recurrido a entrevistas en profundidad, observación participante (asambleas y acciones colectivas) y notas de campo. También se utilizaron datos catastrales, periodísticos y estadísticos que permitieron profundizar el análisis.

Authors: Astana Widhi , Triyono Agus
Published: December 2017

Hati merupakan organ penting dalam tubuh manusia. Organ ini merupakan pusat metabolisme, salah satunya adalah metabolisme obat. Pengobatan konvensional yang menggunakan bahan kimia dapat menimbulkan perubahan pada fungsi hati. Sedangkan pada pengobatan tradisional, efek pengobatan pada fungsi hati masih jarang dipublikasikan. Salah satu penggunaan obat tradisional adalah jamu sebagai sedatif.  Sebuah penelitian diadakan di Balai Besar Litbang Tanaman Obat dan Obat Tradisional (B2P2TOOT) tahun 2013 untuk mengetahui perubahan terhadap fungsi hati pasien-pasien yang mendapatkan terapi ramuan jamu insomnia. Penelitian berupa  observasi  terhadap 30 pasien insomnia yang datang dan berobat di Klinik Saintifikasi Jamu Hortus Medicus. Pasien insomnia yang mendapat terapi ramuan jamu selama 14 hari diobservasi fungsi hatinya. Evaluasi dilakukan pada nilai laboratoris yang merepresentasikan fungsi hati (SGOT dan SGPT) pada hari ke-0 dan hari ke-14. Perbandingan hasil pemeriksaan sebelum dan sesudah terapi menggambarkan perbedaan yang tidak bermakna kadar SGOT dan SGPT subjek penelitian(p>0,05). Semua subjek memiliki nilai SGOT dan SGPT yang normal secara klinis dan laboratoris. Pemberian ramuan jamu untuk insomnia tidak mengganggu fungsi hati.

A Study of Telecommunication Policies and Broadband Penetration for Sweden and South Korea
Authors: Khayyat Nabaz T.
Published: December 2017

Internet broadband technology is the next phase in internet evolution. The emergence of broadband brought many options to internet users. It is evident that in the future, broadband Internet may introduce a big difference in the lives of the public, industry, and the government. However, the diffusion of Broadband is clogged at the regulation crossroads between market, government, and consumer, especially with regard to allow third parties to be involved in building the broadband infrastructure. Controlling access to the development of broadband infrastructure may produce a monopolizing market and limiting the variety and quality of available services. The current study investigates the development of broadband and its penetration in South Korea (the highest country with the access to broadband services), and Sweden (the second highest rate of internet penetration among the OECD countries). The paper overviews the broadband markets in both countries, focusing on their government policies in promoting the technology used and the growth of the market. The paper argues about the challenges facing the market for developing broadband technology, such as increase in the demand and supply for higher speed broadband, increase in the traffic congestion as users spend more time using internet and more data are transferred between individual, software, and applications, etc. the paper finally derives a number of ICT policy objectives and classifies the two countries based on their market approach into: laissez faire (free markets) and markets led by the government’s national plan, with quantified objectives and the regulators instruments strategies to meet the mentioned objectives.
ASSESSMENT OF YIELD COMPONENTS AND THEIR ASSOCIATION IN F2 POPULATIONS OF WHEAT
Authors: Iqbal Touheed , Saad Saeed Ghulam Hassan, Iqbal Hussain,
Published: December 2017

Keeping in view the role of wheat in Pakistan, the current research was conducted to compute the extent of transmissibility and to derive information on the correlation of grain yield with its component traits. Sixteen F2 populations of wheat and their eight parental lines were evaluated at the University of Agriculture, Peshawar-Pakistan during wheat season of 2013-14. Experiment was conducted in randomized complete block design with three replicates. Analysis of variance manifested significant differences among genotypes for all the studied traits. Similarly, mean squares due to parents, F2 populations and parents vs. F2`s were also significant for all the traits under study except harvest index. On the basis of mean performance, maximum grain yield plant-1 among parents was given by Fakhr-e-Sarhad (27.16 g) and PS-05 (26.06 g), while among F2 populations, maximum grain yield plant-1 was given by cross combinations Barsat / Siren (27.93 g), AUP-5008 / Siren (26.09 g) and Tatara / PS-05 (25.65 g). The assessments of heritability and genetic advance manifested that F2 populations, Saleem-2K / Janbaz, Tatara / F.S, AUP-5008 / PS-05 and Tatara / PS-05 had highly heritable characters along with high genetic advance, which offer an opportunity for earlier selection. Hence, more emphasis should be given to these crosses in future wheat breeding programs. Moreover, the perusal of correlation analysis revealed that traits like days to maturity, flag leaf area, plant height, fertile tillers plant-1, biological yield and harvest index appeared to be most essential sources of affecting the final yield, suggesting that upsurge in wheat yield could be admissible by selecting these traits.
Novas luzes sobre a Segunda Sofística
Authors: Martins Paulo , Brener Pedro Zanetta
Published: December 2017

O estudo do período conhecido como Segunda Sofística, assim denominado por Filóstrato, o Velho, tem crescido na academia. À medida que a retórica sofística é reabilitada nos estudos da filosofia e da literatura, – movimento significativo na academia desde, pelo menos, os anos 60 – a compreensão das práticas letradas dos primeiros séculos do Império Romano e de suas auctoritates vem sendo modificada, abandonando estigmas longamente perpetuados. Esse estudo visa a coligir aspectos mais relevantes da prática sofística no período, reunindo importantes contribuições a respeito, de modo a introduzir o leitor em um dos períodos mais profícuos da história romana através da abordagem minuciosa que lhe é dirigida modernamente.
A última defesa de Sócrates – O corpo como metonímia do sensível
Authors: Torrano Jaa
Published: December 2017

Sócrates defende a vida filosófica sob ameaça de pena de morte nos Diálogos de Platão: Górgias, Apologia, Críton e Fédon. Nesse último retomam-se e resumem-se as defesas anteriores. No Fédon, por uma série de reiterados e entrecruzados indícios de apropriação retórica e filosófica do imaginário mítico, a morte se torna metáfora do conhecimento, o corpo metonímia do sensível, o Deus Hades metáfora do inteligível e os Deuses antonomásia das ideias ou formas inteligíveis. Se o sentido dessa apropriação fosse levado em conta na leitura do diálogo, sua compreensão, a meu ver, sofreria uma reviravolta e se tornaria muito mais filosófica.
O onde antes do lugar: as διαστάσεις no De incessu animalium de Aristóteles
Authors: Damião Matheus Oliveira
Published: December 2017

Este trabalho tem por objetivo principal apresentar a exposição que Aristóteles faz das διαστάσεις no De Incessu Animalium (IA). Neste tratado elas são descritas através do exercício das funções anímicas específicas de cada grupo de ser vivo, estabelecendo uma relação de dependência entre as dimensões e as potências da alma que determinado ser vivo possui. Trata-se, portanto, em âmbitos mais gerais, de compreender como a função da alma de um ser vivo subordina sua estrutura, ou, em outras palavras, como a atualização efetiva de um ser vivo traz a tona a manifestação dessas dimensões. Além disso, há uma correspondência exata entre as dimensões e essas funções no corpo humano, estabelecendo-o, assim, como modelo a partir do qual os outros corpos podem ser descritos. Deste modo, os limites das dimensões são manifestos através das potências da alma, cujas distinções se encontram sobretudo no homem.
IMPLEMENTASI PROFESIONALISME GURU DALAM MEMOTIVASI BELAJAR SISWA DI SEKOLAH DASAR
Authors: Sumarwoto Vitalis Djarot
Published: December 2017

Professionalism seems to develop at all sectors in Indonesia today. Many efforts have been undertaken by the decision makers of education to pursue it. Among other efforts done by the authorities is the professional teacher certification. The implementation of professional teacher certification has basically referred to the Law No. 19, year 2005, on the National Education Standard; and the Governmental Regulation No. 74 year 2008 on Teachers, which suggest that teachers are obliged to have relevant academic qualification, competence and certification of educator. The objective of those regulations is only very prestigious i.e. to make them enhance qualified working experience within a certain interval of time. Hopefully, after they are certified professionally, they are able to encourage students to learn, especially for elementary students
An NBO-TS predictive approach for torquoselectivity of ring opening in 3-substituted cyclobutenes
Authors: Yadav Arpita , Prasad Dasari L V K , Yadav Veejendra
Published: December 2017

The torquoselectivity, the inward or outward ring opening of 3-substituted cyclobutenes, is conventionally guided by the donor and/or acceptor ability of the substituent (S). It is typically predicted by estimating the respective ring opening transition state (TS) barriers. While there is no known dissent in regard to the outward rotation of electron-rich substituents from the approaches of TS calculations, the inward rotation was predicted for some electron-accepting substituents and outward for others. To address this divergence in predicting the torquoselectivity, we have used reliable orbital descriptors through natural bond orbital theoretical calculations and demonstrated that (a) interactions nS→s*C3C4 for a lone pair containing substituent, sS→s*C3C4 for a s-donor substituent, sC3C4→p*S for a resonance-accepting substituent and sC3C4→s*S for a s-acceptor substituent constitute the true electronic controls of torquoselectivity, and (b) reversibility of the ring opening event is an additional important contributor to the observed product distribution.
