Authors: ABIDIN Mohammad Zainal , YULIATMO Ragil , GRIYANITASARI Gresy
Published: August 2022

Bating is one of the important stages in the tanning process that has a role as a determinant of leather properties. It is commonly carried out with the assistance of protease enzymes such as papain. By using surfactants, sorbitol and Sodium Dodecyl Sulfate (SDS), it can help the penetration of enzymes into the skin or hides. Thereby, the study aimed to evaluate the use of papain on the bating process of kacang goat skin by assisted surfactants. Accordingly, three different concentrations (1, 1.5, & 2%) of enzymes were added with two different types of surfactants (SDS and Sorbitol) for the bating process. For the result, the leather was evaluated based on physical properties and histology studies. The presence of surfactant in the bating process improves the absorption of papain towards the hydrolysis of non-collagenous proteins. Based on the physical properties and histology studies, they perform better than leather without surfactant agents. Cleary, the surfactant agents can be used as bating auxiliary.

The Hall Effect on MHD 2-Fluid Unsteady Heat Transfer Flow of Plasma in a Rotating System Via a Straight Channel Between Conducting Plates
Authors: Raju T. Linga , Rao B. Venkata
Published: August 2022

Hall currents are used to investigate MHD unsteady two fluid flows and heat transport of plasma along a straight channel of conducting plates. In the two liquid zones, the velocity and temperature fields for the case of conducting side plates are obtained by solving the governing equations using a two-term series under the specified conditions. The distribution profiles are graphically resolved and examined. The distributions are thought to be dependent on the electron-to-total pressure ratio. The flow and heat transfer factors are also influenced by other parameters such as the Hartmann number, Hall parameter, rotation parameter, thermal conductivity and viscosity ratio.
Investigations of Couette Flow Unsteady Radiative Convective Heat Transfer in a Vertical Channel Using the Generalized Method of Lines (MOL)
Authors: Sowayan Ahmed S.
Published: August 2022

This study describes a very efficient and fast numerical solution method for the non-steady free convection flow with radiation of a viscous fluid between two infinite vertical parallel walls. The method of lines (MOL) is used together with the Runge-Kutta ODE Matlab solver to investigate this problem numerically. The presence of radiation adds more stiffness and numerical complexity to the problem. A complete derivation in dimensionless form of the governing equations for momentum and energy is also included. A constant heat flux condition is applied at the left wall and a transient numerical solution is obtained for different values of the radiation parameter (R). The results are presented for dimensionless velocity, dimensionless temperature and Nusselt number for different values of the Prandtl number (Pr), Grashof number (Gr), and the radiation parameter (R). As expected, the results show that the convection heat transfer is high when the Nusselt number is high and the radiation parameter is low. It is also shown that the solution method used is simple and efficient and could be easily adopted to solve more complex problems.

لاشك الحريق في الوقت الحاضر من الأخطار الشائعة التي تصيب الأشخاص والأموال،  ويكاد لا يمر يوم الا ونسمع بحريق اندلع في غابة أو ارض زراعية أو في فندق أو مطعم أو سيارة، حيث أدى تطور الحياة الأقتصادية وتشعبها وظهور الألة في الصناعات ذات التكنلوجيا الكبيرة والحديثة ، ونمو حجم التجارة وتبادلها ، وتطور وسائل النقل في هذا العصر ، وظهور الشركات والمصانع والمصالح الضخمة ذات القيمة المالية الكبيرة الى ازدياد تخوف اصحابها من خطر الحريق الذي قد يصيب ممتلكاتهم ويلحق بها عند تحققه خسائر مالية ضخمة لا تصيب الشخص صاحب المصلحة وحده وانما تؤثر على الأقتصاد القومي للدولة احيانا ، لذلك سعى الأنسان الى محاولة البحث عن طرق فعالة للمحافظة على مصلحته وتعويضه عن الخسائر والاضرار التي تلحق به عند نشوب الحريق في ممتلكاته، وقد ترعرعت فكرة المسؤولية المدنية منذ زمن بعيد وكانت هي الحل الأمثل الذي يتم اللجوء اليه لمواجهة الاخطار التي تصيب الأنسان ، ولكن لم تكن هذه الحل المناسب لمواجهة خطر الحريق، وذلك لأن المشرع العراقي لم يقم بمعالجة الأخطار الناتجة عن الحريق بنص خاص، ولكن أكتفى بالقواعد العامة والمتمثلة بالخطأ والضرر والعلاقة السببية، بكونها الحل الذي يتم اللجوء اليه في حالات الحريق، بيد أن هذه القاعدة لا تحقق الحماية المطلوبة من اخطار الحريق في جميع الحالات، الأمر الذي دفعنا للبحث عن أسس اخرى للمسؤولية المدنية الناشئة عن الحريق لعلها تكون الحل المناسب لمواجهة هذه الاخطار واعطاء كل ذي حق حقه . كما أن هناك الكثير من التطبيقات العملية للحريق حيث تكثر حالات أندلاع الحريق سواء في الاماكن العامة او الخاصة وكذلك في الاراضي الزراعية والغابات والفنادق والمطاعم وغيرها من الاماكن كما يمكن ان تحدث في السيارات ووسائل النقل الاخرى، فوجب تحديد الشخص المسؤول عن هذه الحرائق. وبناءً على ما تقدم فأننا سنسعى من خلال هذه الدراسة الى البحث عن اساس المسؤولية المدنية الناشئة عن الحريق بشكل خاص محاولين دراسة كل ما يتعلق بهذا الموضوع من أحكام، سواء تلك التي وردت في القوانين الخاصة أو القواعد العامة في القانون المدني.
مدى ملائمة عمل الدرون للمبادىء الاساسية القانون الدولي الانساني

Published: August 2022

الاسلحة ليست سوى وليدة الحروب. ومعا تطور التكنولوجيا في العصر الحديث كان هناك تطور موازي في وسائل واساليب الحرب. يضاف الى ذلك التطور في القوانين والاعراف المنظمة لها. كانت الحروب في بداياتها لاتقييد الى حد ما في وسائل القتال. لم يكن لمفهوم التمييز والتقليل من الاضرار اي اساس في القديم. انما الغاية الجوهرية للعدو كانت محو أوتدمير اكبر عدد ممكن من الامكانات العدو المادية والبشرية. لم يكن هناك مراعات في التمييز بين المقاتلين والمدنيين ولا كانت هناك قيود على نوعية الاسلحة المستخدمة. في الحقيقة الاسلحة المفضلة كانت هي التي تمتلك اكبر قوة تدميرية. لكن مع تطور القيم الانسانية ونهضات الشعوب ضد الضلم والاستبداد والحاجة الماسة لضمان حقوق الانسان في الحياة وتحديد نوعية الاشخاص الذين ممكن ان يكونو اهدافاً للقوة المعادية، ظهرت قواعد القانون الدولي الانساني. الهدف الرئيسي لهذه القواعد كانت لتنظيم القوانين المنظمة للحرب بكل جوانبها. استطاعت قواعد القانون الدولي الانساني ان تضع المبادىء الرئيسية لاعتماد واستخدام الاسلحة في المستقبل. حيث ان التطور التكنولوجي خلق نوع من الصعوبات في التكييف القانوني لبعض لاعتماد بعض الوسائل والاسلحة. الدرون او الطائرات بدون طيار هي واحدة من هذه الاسلحة التي اصبحت محل جدال ونقاش فقهاء القانون الدولي حول مدى ملائمتها لقواعد القانون الدولي الانساني وذلك لشحة القواعد والاعراف الدولية التي تنظم عملها. فانقسم الفقهاء بين مويد لاستخدامها وبين معارض لها وفي كلتا الحالتين ونظراً لقلة الحجج القانونية التي يستندون اليها لا يوجد اتجاه قانوني يلزم الدول على اتباعه. وفي رأينا فالحجج التي يستند اليها مؤيدي الدرون اكثر واقعية من حجج المناوئين لها. فهذه الوسيلة ماتم اللجوء لها الا لانها اكثرها دقة واقلها تكلفة. هذه الوسيلة انتشرت بسرعة خاصة في بدايات هذا القرن لقدراتها العسكرية واضراراً بالممتلكات المادية والبشرية والبيئية.

Authors: Castillo G. María Esther
Published: August 2022

Luis Arturo Ramos, through an argument of a police nature, highlights in Los motivos de Bayardo a series of circumstances that obey the cultural policies that the State maintains on literary art and authors. The administrative contexts of politics around the dissemination of art show that the manipulation of relationships between individuals attached to a cultural group or institution implies a form of legitimation of its leaders or of the elites who justify themselves to exercise its dominance over those who aspire to social recognition.

Ultrathin antimony trioxide (Sb 2 O 3 ) was synthesized on ITO substrate by solvothermal method using ethanol as asolvent. The structure, morphological variations and optical properties of the as-prepared sample were characterized.The results indicated that the homogeneously grown sheet of cubic phase of ultrathin Sb 2 O 3 have elliptical crosssection with thickness of 20 nm and diameter of 400-500 nm. Further, an ultraviolet (UV) performancephotodetector based on the (Au/Sb 2 O 3 /Au) was fabricated and examined. The measured Current Voltage (IV) curvesin the dark and under illumination (UV-395 nm) of different intensities indicate the presence of Schottky barrier atthe interfaces between Sb 2 O 3 and Au-electrodes. Photocurrent values of 2.32, 16.5, and 25.58 μA were obtained forintensities of 4, 8 and 12 mW/cm 2 , respectively at bias voltage of +3V, as compared to dark current of 0.78μA.Sensitivity and responsivity values of 40.04 and 6.294W/A were recorded. The current-time (I-T) graph was utilizedto derive the response and recovery times of the sensor under chopped UV-laser at different power intensities. Thesensor exhibited fast response and recovery times of 113.6 ms and 67.2 ms, respectively, making this a high-performance sensor.

ABSTRACT – The study investigated, using content analysis, the patterns of reportage of Nigeria’s Akwa Ibom State House of Assembly by Comfort 95.1 FM, Planet 101.5 FM, and Inspiration 105.9 FM between 2018 and 2019. Results showed similarities/divergences in the news coverage and reportage approach of the stations. Budget/bills/public hearings and motions dominated the news focus. Critical analysis in reportage of the House was almost non-existent. No clear case of media agenda-setting was established, as there was little or zero influence the media had on directing the course of the Assembly. Rather, the media’s focus was determined by the steps of the lawmakers. It was recommended that a weekly magazine program dedicated to the activities of the Assembly be adopted by each radio station. This would help incorporate information that a timed-news bulletin cannot accommodate and fan the flame of investigative journalism and critical analysis of the activities of the Assembly.
 
RESUMO – O estudo investigou, por meio da análise de conteúdo, os padrões de reportagem da Assembleia Estadual Akwa Ibom da Nigéria por Comfort 95.1 FM, Planet 101.5 FM e Inspiration 105.9 FM, entre 2018 e 2019. Os resultados mostraram semelhanças/divergências na cobertura jornalística e na abordagem da reportagem das estações. Orçamento/projetos/audiências públicas e moções dominaram o foco das notícias. A análise crítica na reportagem da Câmara foi quase inexistente. Não foi estabelecido nenhum caso claro de definição da agenda da mídia, pois havia pouca ou nenhuma influência da mídia na direção do curso da Assembleia. Em vez disso, o foco da mídia foi determinado pelos passos dos legisladores. Foi recomendado que cada estação de rádio adotasse um programa de revista semanal dedicado às atividades da Assembleia. Isso ajudaria a incorporar informações que um boletim de notícias cronometrado não pode acomodar e atiçar a chama do jornalismo investigativo e da análise crítica das atividades da Assembleia.

Published: August 2022

Precise and stimuli-controllable transport of charged and neutral guests is a hallmark of cellular processes. Although ion transport has been mimicked with artificial carriers, no such systems are known for electrically neutral ion pairs. We engineered an artificial carrier (1) demonstrating a regulated binding and transport of ion pairs, depending on the photo-controlled translocation of the cation and anion binding domains. The NMR and electrochemical experiments supported by the DFT calculations indicate that UVA-generated V-shaped cis-1, featuring ion binding domains close to each other, shows an unprecedented 74-fold higher extraction rate of ion pairs relative to the native trans-1.

A nickel-catalyzed reductive cross-coupling of cyclopropylamine NHP esters with (hetero)aryl halides is reported. This efficient protocol provides direct access to 1-arylcyclopropylamines, a bioisosteric motif commonly used in small molecule drug discovery. The reaction proceeds rapidly (<2 h) with excellent functional group tolerance and without requiring heat or air-sensitive reagents. The method can also be extended to the arylation of other strained rings. The NHP esters are easily obtained from the corresponding commercially available carboxylic acids in one step with high yields and no column chromatography.

For driving the (photo-) electrocatalytic water splitting reaction both efficient and photostable absorber materials and electrocatalysts are needed in order to make the technology economically competitive. The novel material class of high entropy oxides with their unique and unexpected physicochemical properties is a potential candidate for energy applications. Herein, we report for the first time about the physico- and (photo-) electrochemical properties of ordered mesoporous (CoNiCuZnMg)Fe2O4 thin films synthesized by a soft-templating and dip-coating approach. The high entropy ferrites (HEF) are composed of 15 ‒ 18 nm sized and periodically ordered mesopores building a highly accessible inorganic nanoarchitecture with specific surface areas up to 170 m2/g. The mesoporous HEF thin films crystallize in the cubic spinel structure and were found to be crack-free on the meso- and macroscale. The formation of the spinel structure hosting six distinct cations was verified by means of gracing incidence X-ray diffraction, X-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectrometry, and transmission electron microscopy accompanied with energy dispersive X-ray spectroscopy. Photoelectron spectroscopy gave insight into chemical state of the implemented transition metals supporting the structural characterization data. Analyzed as photoanode for photoelectrochemical water splitting, the HEFs showed only low photoconductivity owing to fast surface recombination as suggested by intensity-modulated photocurrent spectroscopy. When applied as oxygen evolution reaction electrocatalyst, the HEF thin films possess overpotentials of 420 mV vs. RHE at 10 mA/cm2 in 1 M KOH. The results imply that the increase of the configurational disorder within the spinel structure enhances the electronic transport properties. The evaluation of the energy band alignment by Mott-Schottky analysis allows for an estimation which redox reactions can be driven, showing that the materials are theoretically capable of promoting overall water splitting.

Protein function, in many cases, is highly related to its frustration status and hence intimately coupled to the dynamics and conformational equilibria of the protein. The environment surrounding proteins is critical for their dynamics and can dra-matically affect the conformational equilibria and subsequently activities of proteins. However, it is yet unclear how protein conformational equilibria are modulated by their crowded native environments. Here we revealed the immunity protein Im7 was less frustrated and shifted toward its ground state in OMVs than in the aqueous solution. Further experiments showed both macromolecular crowding and quinary interactions with the periplasmic components stabilized the ground state of Im7. Our studies highlight the key role of the OMVs environment played on protein conformational equilibria and subsequently conformation-related protein functions. Furthermore, the long-lasting NMR measurement time of proteins within OMVs underlies it could serve as a promising system to investigate protein structures and dynamics in situ via nuclear magnetic spectroscopy.

Objective: This descriptive and cross-sectional study was conducted to determine women’s opinions about screening tests and early detection of gynecological cancers and breast cancer during the pandemic.Materials and Methods: In this descriptive and cross-sectional study, a descriptive information form developed by the researchers through a literature review was used to collect data.Results: The study was conducted with 220 women who met the study criteria. More than half of the participants reported that they would not visit the doctor due to the pandemic even if they were faced with conditions that might be the indicators of cancer such as pain in the genital or abdominal region (56.4%), abnormal vaginal bleeding (63.2%), difficulty urinating (54.5%), pain during sexual intercourse (55%), collapsed, discolored or deformed nipples (66.8%), redness / sore on the nipple (61.4%) and long-term back pain (54.5%). Of them, 71.4% did not want to have gynecological controls, 69.5% did not want to have cervical cancer screening tests, and 59.5% did not want to have mammography and clinical breast examination.Conclusion: During the pandemic, most women choose to avoid healthcare if they experience potential breast cancer and gynecological cancer symptoms.

En la actualidad son cada vez más los niños diagnosticados con TDHA (Trastorno por déficit de atención e hiperactividad). El trastorno por déficit de atención e hiperactividad es una condición común en la infancia que se caracteriza por la dificultad para mantener la atención y puede estar asociada con síntomas persistentes de hiperactividad e impulsividad que afectan la conducta de la persona. En el caso de los niños, interfiere en el desempeño académico y en sus relaciones interpersonales. Si no se realiza ningún tipo de tratamiento a tiempo, el niño con déficit de atención puede presentar comportamientos inadecuados en la adolescencia y posteriormente convertirse en un adulto problemático, con bajo desempeño laboral y mucha frustración. Muchos de estos niños diagnosticados no poseen con herramientas para empezar su tratamiento y ver mejoras en el futuro. Los niños entre 5 a 7 años, diagnosticados, en su gran mayoría tienen problemas para seguir las normas, suelen saltarse turnos y les falta persistencia para realizar tareas.Con esta aplicación, llamada TDHAPP, se quiere presentar una serie de juegos de concentración y agilidad mental, donde el niño tenga unos pocos minutos al día para poder jugar y así centrar su atención en pasar el nivel del juego. Para esto se consultó a especialistas en el tema, donde ellos hicieron una guía para desarrollar la mejor manera del juego. Actualmente en el mercado existen 3 aplicaciones para que los niños diagnosticados con TDHA realicen distintas actividades lúdicas, sin embargo, no existe un antecedente de una aplicación o juego que tenga en cuenta mejorar su razonamiento a través de ejercicios cognitivos y lúdicos, donde el niño tenga la capacidad de desarrollar concentración unos minutos al día. Como signos de problemas atencionales a los niños con frecuencia les suceden cosas como: ●Cometer errores por descuido. ●Dificultad para concentrarse. ●Parece como que no escucharan. ●No terminar lo que tienen que hacer. ●Ser desordenados y no organizan sus actividades.●Dificultad para hacer esfuerzo mental en cosas académicas o difíciles. ●Perder sus útiles escolares. ●Olvida hacer sus deberes. En una investigación realizada por la Universidad del Rosario realizó en el año 2014 en la ciudad de Bogotá se evaluaron 1.010 niños entre los 5 y 12 años que estudian en colegios públicos y privados de la ciudad, se detectaron que 584 niños de la población analizada poseen síndrome TDHA, una cifra muy alta. Esta es una de las razones por las cuales el juego está basado en la infancia, para niños de 5 a 7 años

En este artículo se presenta la adaptación remota del laboratorio de la asignatura Control Entrada-Salida, el cual tiene como objetivo principal que el estudiante aplique los conceptos de la teoría de control, a la vez que, adquiera habilidades de lógica de programación mediante el software LabVIEW para generar soluciones propias ante un problema real de control. Para la adaptación a modalidad remota se tuvo en cuenta que: se requiere de acceso a un computador con LabVIEW para comunicarse con las plantas y se necesita de una persona que encienda las plantas. Además, dado que solo se cuenta con dos plantas HVAC(Heating, Ventilation and Air Conditioning) y dos plantas VTOL(Vertical Take-Off and Landing), no es posible que los estudiantes se lleven las plantas para sus casas. Inicialmente, se analizaron todas las sesiones de laboratorio que debían ser implementadas, para identificar las necesidades de hardware y/o software en cada una de ellas. De esta manera se realizaron los diseños e implementaciones necesarias para adecuar las prácticas existentes según los requerimientos. En cuanto a la implementación de la adaptación remota del laboratorio de Control: Entrada-Salida, se utilizó el software TeamViewer para solucionar el problema del control remoto de los computadores con LabVIEW. Las adaptaciones remotas de las siete prácticas de laboratorio se implementaron en el periodo 2020-2. Finalmente se realizó una encuesta a los estudiantes para conocer su opinión sobre el trabajo remoto. Se tabularon y analizaron los resultados para darle continuidad al trabajo remoto durante los semestres que sea necesario debido a la contingencia actual.
