Экспериментальные исследования различных полимерных композиций для создания рельефно-фазовых дифракционных решеток для систем дополненной реальности
Authors: Соломашенко А.Б. , Красин Г.К. , Дроздова Е.А.
Published: April 2020

The possibility of copying high-frequency diffraction gratings obtained in a photoresist layer to glass substrates using polymer compositions (“OKM” and “Tekhnovit”) is shown and their comparative analysis is carried out. The mechanism of copying the relief-phase structure is based on a two-stage process consisting of the following steps: obtaining a nickel master, applying a polymer composition to it and curing under the influence of UV radiation. The copying modes were optimized (time, exposure, thickness of the polymer base), and that allowed to obtain relief phase diffraction gratings with a surface relief depth comparable with the initial structure obtained in the photoresist layer. The diffraction efficiency of the resulting gratings was estimated, as well as the change in the depth of the surface relief of polymer copies obtained from one master.

The blood serum samples from healthy rats and rats with inoculated tumors 14 and 28 days after transplantation of cholangiocarcinoma cells were studied using Raman spectroscopy. It was shown that the amide I band intensity differs in the spectra depending on tumor stage and it correlates with the serum protein concentration. The blood glucose concentration increases in some rats, leading to protein glycation and the amide 1 band change. The band at 1670 cm-1 is most pronounced in the spectra on 28 day of the experiment and may be associated with an increase of β-structural elements in protein conformation. The principal component analysis allows evaluating the differences in Raman spectra of healthy rats and rats on day 28 after tumor transplantation.

Artykuł jest krytycznym omówieniem książki Andrzeja Sionka „Charyzmaty. Aktywna obecność Boga w Kościele”. Doświadczenie charyzmatyczne darów Ducha Świętego przez miliony chrześcijan różnych denominacji we współczesnym świecie sprawia, że zagadnienie charyzmatów, w szczególności daru języków czy daru proroctwa, stało się bardzo żywe w dyskursie teologicznym. Andrzej Sionek, sam zaangażowany we współczesny ruch charyzmatyczny, odsłania przed nami teologiczne zawiłości tekstów św. Pawła 1 Kor 12–14. Charyzmaty nie należą tylko do Kościoła pierwotnego. Zielone Święta wciąż trwają, ponieważ Jezus żyje i działa w swoim Kościele.
Patients’ Use of Social Media for Diabetes Self-Care: Systematic Review
Authors: Elnaggar Abdelaziz , Ta Park Van , Lee Sei J , Bender Melinda , Siegmund Lee Anne , Park Linda G
Published: April 2020

Background

Patient engagement with diabetes self-care is critical to reducing morbidity and mortality. Social media is one form of digital health that is available for diabetes self-care, although its use for peer-to-peer communication has not been systematically described, and its potential to support patient self-care is unclear.

Objective

The primary aim of this systematic review was to describe the use of social media among patients (peer-to-peer) to manage diabetes and cardiovascular disease (CVD). The secondary aim was to assess patients’ clinical outcomes, behavioral outcomes, quality of life, and self-efficacy resulting from peer-to-peer social media use.

Methods

We conducted a literature search in the following databases: PubMed, EMBASE, Web of Science, CINAHL, and PsycINFO (January 2008 through April 2019). The inclusion criteria were quantitative studies that included peer-to-peer use of social media for self-care of diabetes mellitus (with all subtypes) and CVD, including stroke.

Results

After an initial yield of 3066 citations, we selected 91 articles for a full-text review and identified 7 papers that met our inclusion criteria. Of these, 4 studies focused on type 1 diabetes, 1 study included both type 1 and 2 diabetes, and 2 studies included multiple chronic conditions (eg, CVD, diabetes, depression, etc). Our search did not yield any individual studies on CVD alone. Among the selected papers, 2 studies used commercial platforms (Facebook and I Seek You), 3 studies used discussion forums developed specifically for each study, and 2 surveyed patients through different platforms or blogs. There was significant heterogeneity in the study designs, methodologies, and outcomes applied, but all studies showed favorable results on either primary or secondary outcomes. The quality of studies was highly variable.

Conclusions

The future landscape of social media use for patient self-care is promising. However, current use is nascent. Our extensive search yielded only 7 studies, all of which included diabetes, indicating the most interest and demand for peer-to-peer interaction on diabetes self-care. Future research is needed to establish efficacy and safety in recommending social media use among peers for diabetes self-care and other conditions.

Authors: Dubey Rupal , Pothuvan Umadoss , Bhamare Pankaj , Singh Alka , Upmanyu Neeraj
Published: April 2020

Hypertension, specifically pulmonary hypertension, is a syndromethat can affect pediatric patients as well as adults. Pulmonary arterial hypertension (PAH) in pediatric patients, while rare, can be a lifethreateningcondition. There is no cure for PAH, only treatment options forchildren that are largely based on the results of adult studies. These therapies, however, can improve quality of life and survival. Treatment can be challenging because of the less approved medications and tolerable dosage forms for pediatric patients. Pediatric pulmonary arterial hypertension (PAH) shares common features of adult disease, but is associated with several additional disorders and challenges that require unique approaches. Current classes of medications primarily used to treat pediatric hypertension include phosphodiesterase inhibitors, endothelin receptor antagonists, and prostacyclins. Additional agents that may be utilized in selected pediatric patients include calcium channel blockers, anticoagulants, and inhalednitric oxide. Updates are provided on issues related to utility of the previous classification system to reflect pediatric-specific aetiologies and approaches to medical and interventional management of PAH. Also updates are provided about currently available drug substance and their details, pharmaceutical dosage forms and their details along with the mechanism of action, pharmacokinetics of the drug. These emerging data are improving the identification of appropriate targets for goal-oriented therapy inchildren. Such data will likely improve future advanced pharmaceutical dosage development and product design to enhance outcomes in pediatric PAH.

Synthesis and Biological Evaluation of Benzimidazoles as Target for α-Glucosidase Inhibitors
Authors: Mishra Shweta , Dahima Rashmi , Sharma Rajesh
Published: April 2020

Diabetes mellitus is rising globally touching more than 180 million people worldwide. This is prevailing mostly in type 2 diabetes and according to WHO report the incidence is likely to be more than doubled by 2030. α-glucosidase inhibitors work by reducing the amount of glucose that the intestines absorb from food. In our previous work, forty-five benzimidazoles analogues were studied using 3D QSAR, HQSAR, and Pharmacophore mapping and based on their results 60 compounds were designed. Docking studies of those designed compounds showed that most of the compounds are bonding with important amino acids LEU 520, ARG 335 and ASP 69 through hydrogen bonds and steric interaction. In this work, synthesis of eleven compounds was done on the basis of molecular docking studies. Compounds containing hydroxyl and alkyl groups (compound no. 3, 9 and 10) were found to be five to eight folds more active with IC90 values in the range of 6.02 ± 1.10 to 33.25 ± 1.20 µg/ml, in comparison with the standard drug, Acarbose (IC90= 290.55 ± 0.081 µg/ml). Thus, these compounds after the toxicity studies could be of therapeutic use in treating diabetes.

Published: April 2020

Aim: The present study was undertaken to examine the effects of Chloroform extract of Argemone mexicana using the paracetamol-induced liver damage in rats as the animal model.

Materials and methods: Chloroform extract of Argemone mexicana (100 and 200 mg/kg body weight) was administered daily in experimental animals. The hepatoprotective efficacy of Chloroform extract of Argemone mexicana (100 and 200 mg/kg) was investigated against paracetamol-induced hepatotoxicity. The levels of serum glutamic oxaloacetic transaminase (SGOT), serum glutamic-pyruvic transaminase (SGPT), serum alkaline phosphatase (ALP), bilirubin and triglycerides were estimated. Moreover, chloroform extract of Argemone mexicana -aided antioxidant defense against hepatotoxic insult of paracetamol was measured by evaluating a number of anti-oxidative biomarkers including reduced malondialdehyde (MDA) in the serum.

Results: Oral administration of paracetamol (500 mg/kg b.wt.) resulted in a significant elevation of liver enzymes in serum such as SGOT, SGPT, ALP, bilirubin and triglyceride levels when compared with the results in the control group. As regards oxidative stress biomarkers, there were increased tissue levels of malondialdehyde in the group treated with paracetamol. All of these results were ameliorated by co-administration of chloroform extract of Argemone mexicana.

Conclusions: These results suggest that the protective role of Chloroform extract of Argemone mexicana in the prevention of PCM-induced hepatic toxicity in rats was associated with a decrease of oxidative stress in hepatic tissues.

A feature of financing higher education institutions is the application of a standard scheme: financing from a general fund, the expense of a special fund, sponsorship, which does not fully meet the needs of the educational and innovative model of a higher educational institution as an element of the national innovation system. The proposed mechanism of mixed educational lending provides for the deposit participation of banks in financing student education, a feature of which is the reimbursement of interest from the budget or from third parties for the use of credit. This will improve the educational process and the specialists’ professionnal level. Based on the possible ratios of excess or deficit of funds, three types of financial stability for each of two possible types of quality of financial condition are identified.

Introduction/Objective. Gunshot residue (GSR) on the skin of a victim are important evidence, with far better precision, for reconstructive questions in the forensic investigation of cases involving gunshot wounds. The aim of this experimental study was to analyze if there was any significant difference in macroscopic characteristics of wounds that were caused with different types of weapons from three different distances. Methods. This study was conducted at the Department of Ballistic and Mechanoscopic Expertise, Federal Police Directorate. Experiments were done on pigskin and 55 samples were made. Shooting was conducted using a system for safe firing. Samples of the pigskin were shot by firing projectiles from four different weapons and from three different distances, (contact wound, five centimetres and 10 centimetres). Results. At the contact range, wounds caused by automatic rifle had horizontal, vertical diameters larger than those made by pistols. Diameters on the wounds that were caused with different pistols, were similar. At the range of five centimetres, the narrowest part of contusion ring significantly differs even through pistol wounds. Diameters at the range of 10 centimetres are in favor of these results. Gunpowder residue scattering area was statistically different depending of type of weapon (p = 0.004). Conclusion. Wound diameters and surface area are useful for differentiation between pistol and rifle caused wounds. It is unsecure method for determination of pistol caliber or fire range. GSR have much greater potential for future analyses, but even GSR cannot be used to determine pistol caliber.

Authors: Kapeli Sarah Ann , Manuela Sam , Milojev Petar , Sibley Chris
Published: April 2020

Introduction: Our study investigated the development of social support experienced by Pacific men and women across the adult lifespan in New Zealand (18 to 65 years of age).   

Methods: We examined differences in social support using data from the first six annual waves of the New Zealand Attitudes and Values Study (N = 501 women and 238 men) using an age-based latent growth model.

Results and Discussion: Mean levels of social support decreased as Pacific peoples aged. More specifically, Pacific men demonstrated a significant decrease in social support and older Pacific men demonstrated the lowest levels of support of all Pacific peoples. In comparison, Pacific women maintained higher levels of social support compared to Pacific men, with social support remaining relatively stable across the lifespan of Pacific women.

Conclusion: Our research explores the importance of social support and its link to health and wellbeing among Pacific communities in New Zealand. This is important because we need to understand the factors that could buffer outcomes of low social support such as mental illness and possibly suicide among Pacific peoples.
“Não me aquenta, nem me arrefenta”: considerações a propósito da origem e evolução dos verbos terminados em -entar em português
Authors: Pereira Rui Abel Rodrigues
Published: April 2020

Os verbos terminados em -entar, como amolentar, apodrentar, avelhentar, endurentar, enfraquentar, adormentar, acrescentar ou afugentar, têm suscitado, ao longo dos anos, análises diversas no que diz respeito à sua morfologia e/ou ao seu modo de construção. Este subconjunto de verbos derivados é especialmente interessante pois não apenas nos fornece pistas sobre o processo de geração e de desaparecimento dos afixos, como também permite analisar como se desenrola o fenómeno de competição afixal (cf. amolentar vs. amolecer; apodrentar vs. apodrecer).Neste artigo, para além de apresentarmos as questões fundamentais que a descrição destes verbos suscita em termos lexicogenéticos, analisaremos o percurso diacrónico do constituinte derivacional -entar desde os primórdios da nossa língua, avaliando os efeitos do fenómeno de competição mantido com outros processos verbalizadores, especialmente com aqueles que envolvem o elemento sufixal -ecer.

Published: April 2020

La germinación in vitro de semillas de E. algibicum, especie endémica de la Sierra de Grazalema, S de España, así como la inducción de yemas múltiples y el desarrollo posterior de brotes, se consiguió en el medio de cultivo de Murashige y Skoog a mitad de concentración, con 3% de sacarosa y citoquinina (BAP) a las concentraciones de I y 2 mg l (ECH-1, ECH-2). La germinación de las semillas se incrementó significativamente de 38% a casi 100% tras la escarificación. El número medio de yemas formado después de 35-40 días fue de 8,6 y 6,9 en los medios ECH-1 y ECH-2 respectivamente. Los brotes fueron posteriormente enraizados en el mismo medio nutritivo pero sustituyendo la citoquinina por la auxina IBA (0.2 mg 1-1 ). En este medio, se consiguió un porcentaje medio de enraizamiento de 35,49 después de 25-30 días, y en algunos casos la formación de masas de callo en las zonas de los brotes en contacto con el medio nutritivo. Finalmente, se ensayó la aclimatación de estas plantas a suelo mediante reducción progresiva de la humedad relativa y tras varios tratamientos que incluyeron el uso de CO2 , la adición de inoculo de micorriza (Glomus deserticola) al substrato de cultivo, así como el uso de un medio de cultivo sin reguladores de crecimiento y mitad de sacarosa previo paso a suelo. Los porcentajes de supervivencia después de 60 días en suelo fueron mayores para la plantas sometidas a los tratamientos con CO2 , aunque los porcentajes medios fueron algo bajos.

La mayoría de los tipos aparecen en la primera mitad del año (excepto Palmae y Casuarina), produciéndose las semanas de máxima recogida de polen antes de la semana quince del año. La variación, a lo largo del año, de las concentraciones polínicas semanales se caracterizan por un perfil gráfico homogéneo, excepto Palmae y Citrus, en los que se observan continuas subidas y bajadas de las concentraciones.
Contribution à l'étude des groupements rupicoles des Bokkoya (Littoral du Rif Central, Maroc)
Authors: Deil Ulrich , Hammoumi Mohammed
Published: April 2020

Le massif calcaire des Bokkoya du littoral rifain est la partie la plus sèche des côtes méditerranéennes du Maroc. Apres une introduction aux conditions physiques et phytochorologiques de la région, les groupements rupicoles sont décrits scion la methode phytosociologique. Les falaises septentrionales sont couvertes par le Sedowilczekiani-Sonchetummasguindalii ass. nov., une association endémique du sous-secteur Nekor- Bokkoya (secteur Nekor-Triffa). Sur les pentes méridionales, on observe d' autres groupements appauvris du Poterion ancistroidis. Les fissures oinbragées et nitrifiées au pied des falaises sont colonisées par le groupement á Mercurialisambigua et Theligonum cynocrambe, les éboulis par celui á Succowia balearica. Sous des surplombs vivent des peuplements á Sarcocapnos enneaphylla. Les séries de contact sont illustrees par une figure. Un schéma syntaxonomique des groupements rupicoles du Nord du Maroc est presenté. Finalement, les associations et leurs vicariantes sont discutées dans le contexte ouest-méditerranéen.

Published: April 2020

Se ha realizado una recopilación sobre las asociaciones de la clase fitosociológica Cisto- Lavanduletea en el sur de la Península Ibérica (Andalucía, España). La gran riqueza fitocenológica viene avalada por la diversidad en Andalucía de ambientes requeridos por estas formaciones: suelos silíceos degradados, de textura compacta o arenosa, territorios desde el nivel del mar hasta cerca de los 1700 m y precipitaciones no muy escasas siempre con régimen pluviométrico y térmico de tipo mediterráneo. Las alianzas detectadas han sido Ulici argentei-Cistion ladaniferi (de suelos compactos y áreas térmicas lluviosas), Calicotomo spinosae-Cistion ladamferi (de suelos compactos y áreas térmicas secas), Coremion albi (de suelos arenosos y áreas térmicas secas), Cistion laurifolii (de suelos compactos y áreas frías) y Stahelino-Ulicion baetici (sobre rocas ígneas ultrabasicas). Se han reconocido un total de 17 asociaciones, proponiéndose 1 nueva subalianza de areal aljíhico (Ulici borgiae-Calicotomenion villosae), 2 nuevas Combinaciones (Genisto hirsutae-Cistetum ladaniferi cistetosum libanotis y Teucrio compacti-Cistetum ladaniferi cistetosum populifolii), 1 nueva subasociación (Lavandulo caesiae-Genistetum equiseliformis calicotometosum intermediae) y lectotipificándose una asociación (Teucrio mariani-Cistetum laurifolii).

Transferencia de saberes tradicionales alimentarios. El caso de las productoras de tlayudas en Tlalixtac de Cabrera, Oaxaca (México)
Authors: Vasconcelos-Ramírez Adriana , Tapia-Guerrero Luis Arturo , López-Cruz Juana Yolanda
Published: April 2020

Objetivo: el documento reporta los resultados de un estudio de caso cuyo objetivo fue analizar los factores sociales y familiares que intervienen en el proceso de transferencia de saberes alimentarios tradicionales dentro de la producción de tlayudas en el municipio de Tlalixtac de Cabrera, Oaxaca.Metodología: en el estudio se emplearon métodos mixtos que incluyeron la realización de entrevistas semiestructuradas y el levantamiento de una encuesta a 110 productoras. Resultados: se encontró que la elaboración de tlayudas en el municipio ha perdurado a lo largo del tiempo en el marco de un sistema agroalimentario localizado, en el que resulta central la transferencia de un saber-hacer tradicional. Esta “sistematización” y “localización” salvaguarda un componente cultural, social y simbólico de la actividad productiva frente a shocks externos que afectan contextualmente a los pequeños productores en el estado. Limitaciones: no se tuvo acceso a todos los agentes que participan en la cadena de valor. Conclusiones: la continuidad de la producción de tlayudas frente a shocks externos que han presionado al sistema sugiere que dicha actividad ha sido reinterpretada como un patrimonio cultural que, en el contexto de la globalización, se convierte en un recurso estratégico para el desarrollo económico, siendo la participación de la mujer fundamental como portadora del patrimonio alimentario que se concreta en un nuevo espacio de consumo.

Published: April 2020

Nghiên cứu này được thực hiện để xác định tính chất dẫn nhiệt có hiệu của vật liệu dẫn nhiệt xếp lớp khi các lớp được giả sử là có mặt phân giới nhẵn và hoàn hảo trong trường hợp các vật liệu thành phần là dẫn nhiệt bất đẳng hướng. Hai giả thuyết đó cho thấy thành phần pháp tuyến của vector dòng nhiệt và trường nhiệt độ là liên tục khi đi qua mặt phân giới giữa các lớp vật liệu. Để xác định được tensor dẫn nhiệt có hiệu của loại composite này thì ta cần phải xác định nghiệm các trường và biết rằng nó chỉ thay đổi theo phương xếp lớp. Nghiệm giải tích của bài toán sẽ được so sánh với các kết quả mô phỏng bằng phương pháp phần tử hữu hạn thực hiện bằng phần mềm Comsol Multiphysic và với các giới hạn Voigt - Reuss.

La institución del Estado como una veluti mente
Authors: Rodríguez Benavidez Iván Ramón

La exposición de los regímenes políticos del Tratado Político no es aleatoria; Spinoza expone en primer lugar el que menos conviene, esto es, el monárquico, después el que conviene más, la aristocracia, y finalmente la democracia, régimen al que concibe como el más perfecto. Este criterio de exposición no sirve de criterio para investigar cuál es el valor de la democracia para Spinoza, pero nos permite investigar cuál es el principal obstáculo o peligro que debe enfrentar la democracia para que se pueda instituir realmente por parte de los ciudadanos, y para que no sea instrumentalizada por los intereses particulares de los gobernantes y políticos de turno.

Authors: SARIDOĞAN Hasan Önder , GÜLŞEN Mustafa Alpin
Published: April 2020

Geçiş ekonomisi, merkezi olarak planlanan bir ekonomiden serbest piyasa ekonomisine dönüşmekte olan bir ekonomiyi ifade etmektedir. Geçiş ekonomileri, piyasa temelli kurumlar geliştirmeyi amaçlayan bir dizi yapısal dönüşümden geçmektedir. Bu çalışmada geçiş ekonomilerinde 1998-2017 dönemine ait kamu harcamalarının ekonomik büyümeye olan etkisi incelenmiştir. Bu kapsamda F testi ve Hausman testi uygulanmıştır. Panel veri regresyon modellerinin ele alındığı analizde, sabit etkiler modelinin uygun olduğu görülmüştür. Model, varsayımlardan sapmalara karşı geliştirilen Driscoll-Kraay dirençli standart tahmincileriyle tahmin edilmiştir. Analizde 21 geçiş ekonomisinin 1998-2017 dönemine ait kamu harcamalarının ekonomik büyümeye olan etkisi ele alınmıştır. Analiz sonucunda, 21 geçiş ekonomisinin iktisadi büyümesinde kamu harcamalarının pozitif etkisi olduğu bulgusuna ulaşılmıştır. Bu bağlamda, kamu nihai tüketim harcamalarındaki %1’lik artış reel gayri safi yurtiçi hasılayı %0,42 oranında artırmaktadır. Ek olarak bu sonuç, geçiş ekonomilerinin kamu kaynak tahsisinde etkinlik, siyasi istikrarın iktisadi istikrara olan etkisi, merkezden planlanan ekonomilerin serbest piyasaya geçişteki başarısı ve geçiş ekonomilerinin küresel rekabetteki konumu gibi hususlarda birtakım çıkarımlar yapmaya imkân tanımaktadır.
