Spin-Orbit Coupling corrections for the GFN-xTB method
Authors: Jha Gautam , Heine Thomas
Published: January 2023

Spin-orbit coupling (SOC) is crucial for correct electronic structure analysis in molecules and materials, for example in large molecular systems as in superatoms, for understanding the role of transition metals in enzymes, and when investigating the energy transfer processes in metal-organic frameworks. We extend the GFN-xTB method, popular to treat extended systems, by including SOC into the hamiltonian operator. We followed the same approach as previously reported for the density-functional tight-binding (DFTB) method and provide and validate the necessary parameters for all elements throughout the periodic table. The parameters have been obtained consistently from atomic SOC calculations using density-functional theory. We tested them for reference structures where SOC is decisive, as in transition metal containing heme moiety, chromophores in metal-organic frameworks, and in superatoms. Our parametrization paves the path for incorporation of SOC in GFN-xTB based electronic structure calculations of computationally expensive molecular systems.
TO PLAY OR NOT TO PLAY: THE USE OF GAMIFICATION IN THE FASHION RETAIL INDUSTRY
Authors: Goldberg Roland , Nel Valeska
Published: January 2023

The COVID-19 pandemic has devastated the world economy, affecting many industries. Given the growing inadequacies of traditional marketing communication channels in the digital age, fashion retailers are looking at innovative ways of communicating with consumers. Gamification’s efficacy as a marketing communication’s tool can be linked to its potential to satisfy users’ intrinsic needs, ostensibly through evoking a pleasurable consumer experience via autotelic use reminiscent of videogame engagement. The goal of this study was to investigate the use of gamification in the fashion retail industry. A qualitative approach was followed by means of an exploratory research design. Judgement sampling was used to identify a total of 25 participants from whom data was gathered by means of conducting three focus groups. Data was analysed by means of the Morse and Field approach using Atlas.ti. The results indicate that consumers are aware of gamification and enjoy using it, describing it as a fun and enjoyable experience. Consumers’ primary motivation for using gamification applications is to gain financial benefit in the form of discounts, vouchers, points or rewards. The dominant challenges identified with using gamification applications are that they do not provide a user-friendly interface, as well as privacy and security concerns and connection issues.
IMPACTS OF THE PUBLIC PROCUREMENT ACT 2007 ON THE PROCUREMENT OF PUBLIC PROJECTS IN NIGERIAN TERTIARY INSTITUTIONS
Authors: Maduekeh Chiedu Okwudili , Obinwa Ifeoma Nancy
Published: January 2023

Tertiary institutions often require huge investments in capital projects for effective learning to be actualized. In Nigeria, public tertiary institutions are usually funded fully by the Federal Government through interventionist institutions like Tetfund which are usually saddled with the responsibility of providing the fund required to achieve both human and infrastructure development required for effective knowledge impartation. The public procurement system in Nigeria has over the years been known for abuse which has led to a myriad of problems including inflation, delay, poor quality of work, and outright project abandonment. Before the enactment of the Nigerian public procurement act in 2007, there were no specific procedures laid down for the procurement of public goods and services in Nigeria. The implication of this was that every procurement entity in Nigeria such as Ministries, Parastatals, and Agencies of Government was at liberty to decide and adopt any procurement method and strategy of their choice to determine and award contracts to contractors of their choice. This situation was largely responsible for the observed lapses in the procurement of public goods and services. With the advent of the Public Procurement Act (PPA) in 2007, one expected these perceived lapses to abate. This study, therefore, assesses the impact of the PPA in the procurement of public projects in the Federal Polytechnic, Oko, and Nnamdi Azikiwe University Awka, both Nigerian public Tertiary Institutions in Anambra State, South-East Nigeria. Data for the study were collected using a structured questionnaire distributed to staff of the physical planning units of the two institutions, construction industry professionals in the Faculty of Environment Sciences both at the Nnamdi Azikiwe University, Awka, and Federal Polytechnic, Oko all in Anambra State as well as Quantity Surveyors in the state. In all, a total of one hundred and twenty-eight (128) structured research questionnaires were distributed; data collected were analyzed using descriptive statistics. Based on the outcome of the research, appropriate recommendations were made including a call for regular training and retraining of procurement officers to keep them abreast with global trends as well as provisions of the Nigerian procurement Act.

Bleeding is one of the most important factors affecting an operation's success. The controlled hypotension method reduces bleeding; therefore, it provides a satisfying bloodless surgical field during operation. Objective: To evaluate and compare the effectiveness of (Remifentanil, Nitroglycerin, Esmolol, and Nitroglycerin + Esmolol) on hemodynamic parameters and the effectiveness of these drugs in providing a satisfactory bloodless surgical field during rhinoplasty surgery. Patients and Methods: 200 adults aged 20 to 45 years were randomly divided into four groups: Remifentanil (R), Nitroglycerin (N), Esmolol (E), Nitroglycerin + Esmolol (N+E). Systolic blood pressure, diastolic blood pressure, mean blood pressure, and heart rate (SBP, DBP, MBP, and HR) were recorded before anesthesia induction until the operation's end. The bleeding score and the visibility of the surgical field were rated by the surgeon as follows: (0) No bleeding, (1) Mild bleeding - no aspiration required, (2) Mild bleeding - intermittent aspiration is required, (3) Moderate bleeding - frequent aspiration is required, (4) Severe bleeding-constant aspiration is required, (5) Severe bleeding, operation stopped because of surgical field invisibility. Results: As a result, during operation, decreased values of (SBP, DBP, and MBP) were statistically significant in all groups. At the same time, the value of HR showed a statistically significant decrease in the (E) and (R) groups, while there was a statistically significant increase in the (N) and (N+ E) groups. Patients in the (E) and (R) groups had a statistically significantly lower bleeding score than the patients in the (N) and (N + E) groups. Conclusion: Patients had better Hemodynamic stability and surgical field visibility after applying Esmolol and Remifentanil.

ABSTRACT           The use of distribution transformers has a very important role in the distribution of electrical energy in a distribution system. The transformer that is used must be maintained properly so that its reliability is maintained stable, so that it will avoid the form of interference. In the event of a disturbance, this will result in the interruption of the continuity of electricity distribution to consumers and also a loss for consumers and PLN itself. Some of the disturbances that often occur are due to overloads, unbalanced loads, lightning strikes and internal disturbances in the transformer (interference originating from the transformer itself). Through this research will be taken a case study on a 20 kV distribution network at PT. PLN (Persero) Rayon Medan Baru. Keywords :Distribution System, PLN, Unbalance Load.Penggunaan trafo distribusi mempunyai peranan yang sangat penting dalam pendistribusian energi listrik pada suatu sistem distribusi. Trafo yang digunakan harus dijaga dengan baik agar keandalannya terjaga stabil, sehingga terhindar dari bentuk gangguan. Apabila terjadi gangguan maka akan mengakibatkan terputusnya kontinuitas penyaluran tenaga listrik ke konsumen dan juga kerugian bagi konsumen dan PLN itu sendiri. Beberapa gangguan yang sering terjadi adalah karena beban lebih, beban tidak seimbang, sambaran petir dan gangguan internal pada trafo (gangguan yang berasal dari trafo itu sendiri). Melalui penelitian ini akan diambil studi kasus pada jaringan distribusi 20 kV di PT. PLN (Persero) Rayon Medan Baru.Kata Kunci : Sistem Distribusi, PLN, Beban Tidak Seimbang

Mediante un análisis bibliométrico y técnicas de análisis estadístico multivariado se analizó la estructura teórica del emprendimiento social a través de la exploración y determinación de la relación entre las dimensiones y variables que componen este constructo. La investigación permitió determinar las relaciones entre cuatro dimensiones con sus correspondientes variables: social, gubernamental, de fomento estratégico del emprendimiento social y dispositivo de investigación social. Se constató que, en los países con mejor desarrollo en el ámbito del emprendimiento social, existía un equilibro entre su desarrollo teórico y práctico. Se destacaron los dispositivos de investigación social para proveer una base teórica y, así, poder utilizar el marco de la gestión de la información y el conocimiento. También se reveló que las economías más desarrolladas, paradójicamente, son las que muestran mejores indicadores teóricos y prácticos de emprendimiento social, en contraposición con países en vías de desarrollo en los que es más imperioso la solución (de manera sostenible) a problemas sociales acumulados por siglos. Por otra parte, el emprendimiento social puede contribuir con los Objetivos de Desarrollo Sostenible en los países con economías más débiles, pero su impulso debe planearse y aplicarse con un enfoque práctico, basado en el desarrollo económico y comercial que sustente al ideal romántico o político.

Este trabajo tuvo como objetivo proponer parámetros de orientación a los gerentes de una pequeña empresa para la mejora de la toma de decisiones relacionada con la gestión de carteras de proyectos. El trabajo se llevó a cabo a través del establecimiento de una metodología con criterios homogéneos y claros, basada en la consolidación de los datos de las diferentes iniciativas presentes en el portafolio de la organización estudiada. La investigación exploratoria se realizó a través de un estudio de caso cualitativo y cuantitativo de una microempresa de comercio electrónico en el segmento de las artes. Se caracterizó el escenario actual de la compañía y se propuso un modelo de gestión con procesos de maximización del desempeño, monitoreo y control de la cartera de proyectos. De esta manera, se verificaron los puntos de atención en relación con los riesgos financieros de la cartera consolidada, así como las oportunidades para equilibrar líneas y tipos de productos. Para los objetivos a largo plazo también se identificó la importancia de equilibrar iniciativas financieramente atractivas con proyectos estratégicos. El principal aporte del trabajo, sin embargo, fue la propia formalización del proceso de gestión de cartera de proyectos, lo que permitirá a la empresa optimizar la asignación de sus recursos en busca de sus objetivos organizacionales.
Identificación de tendencias en investigaciones en genética en la escuela secundaria: Revisión bibliográfica 2013-2021
Authors: Hinestrosa Leidy Lorena , Cabrera Castillo Henry Giovany
Published: January 2023

Este artículo de enfoque metodológico cualitativo de tipo interpretativo, pretende identificar las tendencias con las que se ha tratado la genética en la escuela secundaria, mediante la realización de una revisión bibliográfica donde se analizaron 39 artículos; seleccionados de dos fuentes académicas reconocidas (Google Scholar y Scopus), correspondientes al periodo de tiempo comprendido entre el año 2013 y el año 2021. Los resultados obtenidos permitieron determinar que el tratamiento de la herencia biológica en la escuela secundaria se han visto influenciado por: la divulgación realizada por los medios de comunicación; la centralización en los procesos de enseñanza desde la genética clásica y la molecular (incidiendo en un determinismo genético); el diseño de recursos tecnológicos, experimentales y modelizaciones para facilitar su aprendizaje; las implicaciones previstas por la riqueza del lenguaje genético; las concepciones que presentan los estudiantes alrededor de la genética y la vinculación de las Cuestiones Sociocientificas (CSC) como una alternativa en el proceso educativo alrededor de ella. Así mismo, se evidencio la ausencia de elementos epigenéticos como componente alternativo del tema. Concluyendo, la revisión bibliográfica, además de identificar las tendencias que le dan forma al estudio de la genética en el contexto escolar permitió señalar lo inusual que es abordaje de conceptualizaciones complementarias, por ejemplo, la ausencia de reflexiones alrededor de la epigenética, impide explicaciones que indiquen la incidencia de factores ambientales (nutrición, estilos de vida y eventos traumáticos) en el genoma de los seres vivos y permitan replantar la validez del denominado hermetismo genético.
معجم الأخلاق في مدونة طه عبد الرحمن: مدخل منهجي لدراسة المفهوم الأخلاقي
Authors: هُمَام محمد
Published: January 2023

ينطلق البحث من أنَّ (المفهوم الأخلاقي) هو المادة الأساسية التي اشتغل عليها طه عبد الرحمن في مشروعه العلمي الفلسفي، ويكاد يكون حجرًا أساسًا لمدونة قائمة الذات في مجال (فلسفة الدين)، وتقوم المدونة على مجمعات مفاهيمية واصطلاحية. وسعى البحث إلى الكشف عن أصولها النظرية، وعن مقتضياتها الفكرية واللسانية والمنطقية، فعرض البحث منهج طه عبد الرحمن في وضع المفاهيم الأخلاقية من خلال استثماره لإمكانات اللغة العربية، من حيث: التراكيب والاشتقاق، والصيغ الصرفية، ومن خلال المقابلة، وتماثل الصيغ، وتماثل مقاطع الكلمات، لعكس التقارب في المفاهيم الأخلاقية، وعرض البحث خصائص المعجمية الأخلاقية في مدونة طه عبد الرحمن، من خلال نقد مجهود ابن رشد في توظيف المفهوم الأخلاقي المنقول عن النص الفلسفي اليوناني عبر آليتي (التلخيص) و(الشرح)، ومن خلال تقويم طه لأعمال الترجمة العربية للمفهوم الأخلاقي اليوناني. وقد استثمر طه في تقويمه للترجمة العربية للمفهوم الأخلاقي نظرية اللسانيات التداولية، ونظرية التخاطب الحديثة، وهو تقويم يقوم على اعتبار اللسان الطبيعي نسقًا مترابط العناصر، وليس قاموسًا للمفردات المجزأة. كما تناول مجهود طه في توفير المستند الفكري للغة الفلسفية وللمفهوم الأخلاقي، من خلال: لغة علم الكلام، ولغة التصوف، ولغة علم الأصول، ولغة علم التفسير... وخلُص البحث إلى أنَّ المفهوم الأخلاقي في مدونة طه عبد الرحمن ينشأ داخل نسق متكامل من منظور تداولي وتخاطبي وتقريبي وترجمي واصطلاحي.
هل يحتاج علم الاجتماع إلى تقويض بنية الاستعمار؟
Authors: غني هناء خليف
Published: January 2023

هذا المقالُ مراجعة لثلاثةِ كُتبٍ بحثت الأهميةَ الفكريةَ التي دفعت إلى فكّ الارتباط بالنماذج المنوطة بالمركزية الأوروبية في علم الاجتماع؛ حيث يتبنّى كُلٌّ منها، أي الكتب، مقاربةً مختلفةً. إن كتاب "النظرية الاجتماعية خارج المعتمد" لأستاذ علم الاجتماع سيد فريد العطاس (Syed Farid Alatas) وأستاذة علم الاجتماع والأنثروبولوجيا ﭭينتا سنها (Vineeta Sinha) ، يوظّفُ الدراسة الغيَرية المقارنة للمنظرين الاجتماعيين غير الغربيين المشهورين والمغمورين نسبيًا. ويطوّرُ كتاب "علم الاجتماع التاريخي العالمي"، الذي اشترك في تحريره أستاذ علم الاجتماع والدراسات الآسيوية جوليان غو (Julian Go)، وأستاذ العلاقات الدولية وعلم الاجتماع التاريخي جورج لاوسن (George Lawson) ، نموذجًا إرشاديًا ، يبتعد عن الاختزال المنهجي الذي ينطلق من "القومية المنهجية"، الذي يعرف ويحدّد علم الاجتماع المعاصر والتخصصات المتعلقة به. أما الكتاب الثالث في هذه المراجعة، والموسومُ بــــ"البدائل السوسيولوجية للدين: نظرةٌ بعيون غير غربية" لأستاذ علم الاجتماع والأنثروبولوجيا جيمس ﭪ. سبيكارد (James V Spickard) ؛ فيقلب علم اجتماع الدين التقليدي رأسًا على عقب، وذلك عبر فحصه للمسيحية، والإسلام المعاصرين، باستخدام مفاهيم تطورت في الصين القديمة وتونس خلال القرن الرابع عشر. إن تلك الكتب الثلاثة لها غايةٌ متماثلة، هي: تسليط الضوء على حدود وهفوات علم الاجتماع المعني بالمركزية الأوروبية، الذي يُركز على الأمّة ذات السّيادة المستقرّة والفرد، لكنه يفشلُ في تقديم الاعتراف الضروري بالعلاقات المترابطة، والاتكال المتبادل الذي يدفع الهويَات الاجتماعية إلى التحرك عبر الزمان والمكان.

Published: January 2023

Keberhasilan fertilisasi in vitro tidak hanya dipengaruhi oleh oosit tetapi juga kualitas spermatozoa, konsentrasi spermatozoa, dan lamanya waktu inkubasi. Penelitian ini bertujuan untuk mengevaluasi karakteristik spermatozoa domba post-thawed yang diinkubasi pada waktu dan konsentrasi yang berbeda dalam medium fertilisasi. Spermatozoa domba berasal dari semen beku domba garut dan ekor gemuk. Konsentrasi spermatozoa yang digunakan adalah 1 dan 5 juta spermatozoa/mL. Setiap kelompok spermatozoa diinkubasi dalam inkubator CO2 5% pada suhu 38,5oC selama 0, 3, dan 6 jam. Setiap akhir masa inkubasi, spermatozoa dievaluasi pola gerak, motilitas, MPU, dan TAU sebanyak tiga ulangan. Hasil penelitian menunjukkan bahwa motilitas total, motilitas progresif, MPU, dan TAU pada kedua bangsa domba dengan konsentrasi 1 dan 5 juta menurun secara signifikan dengan bertambahnya waktu inkubasi. Pola pergerakan spermatozoa kedua bangsa domba pada konsentrasi 1 juta menunjukkan hiperaktivitas pada jam ke 3 inkubasi dengan nilai STR 0,47-0,49% dan nilai LIN 0,33-0,34%, sedangkan pada konsentrasi 5 juta menunjukkan adanya hiperaktivitas pada jam ke 6 inkubasi dengan nilai STR 0,69-0,80% dan nilai LIN 0,52-0,55%. Selama inkubasi, spermatozoa menunjukkan pola renang sedang dengan nilai VCL 50,70-77,85 µ/s. Penelitian ini menyimpulkan bahwa kualitas spermatozoa setelah inkubasi menurun seiring dengan penambahan waktu inkubasi. Spermatozoa dengan konsentrasi 5 juta menunjukkan nilai motilitas total yang tinggi tetapi nilai progresifnya lebih rendah dibandingkan dengan konsentrasi 1 juta. Hiperaktivitas spermatozoa dengan konsentrasi 1 juta dapat terjadi pada jam ke 3 sedangkan kosentrasi 5 juta dapat terjadi pada jam ke 6 waktu inkubasi.

Indonesia merupakan salah satu negara dengan jumlah penduduk yang relatif tinggi, sehingga diperlukan upaya dalam menekan laju pertumbuhan penduduk seperti mengembangkan potensi obat antifertilitas berbahan dasar herbal. Daun pepaya Calina merupakan varietas tanaman pepaya di Indonesia yang memiliki beberapa kandungan fitokimia yang berpotensi sebagai agen antifertilitas. Penelitian bertujuan mengetahui potensi ekstrak etanol daun pepaya Calina sebagai agen antifertilitas terhadap Indeks Gonadosomatik (GSI) dan perkembangan folikel ovarium tikus Wistar. Penelitian dilakukan selama 30 hari menggunakan 25 ekor tikus Wistar betina umur ± 15 minggu. Perlakuan terdiri dari 5 kelompok yaitu kontrol (akuades), kontrol positif (pil kontrasepsi dosis 14,184 mg/kg BB), ekstrak etanol daun pepaya Calina dosis 200mg/Kg BB, 300 mg/Kg BB dan 400 mg/Kg BB yang diberikan secara oral gavage 1 ml. Parameter terdiri indeks gonadosomatik dan perkembangan folikel ovarium yang terdiri dari folikel primer, sekunder, de graaf, korpus luteum dan atresia. Pada hari ke 31 dilakukan pembedahan dan pengambilan ovarium pada tikus. GSI dihitung dengan membagi bobot ovarium dengan bobot badan tikus, sedangkan pengamatan folikel ovarium dilakukan dengan pembuatan preparat histologi menggunakan metode paraffin (Pewarnaan HE). Seluruh data dianalisis menggunakan One Way Anova dengan uji lanjut Duncan. Hasil menunjukan bahwa dosis 300 mg/Kg BB dapat menurunkan bobot ovarium, menurunkan indeks gonadosomatik, menurunkan jumlah folikel primer dan sekunder, menurunkan luas folikel de graaf, serta meningkatkan jumlah folikel atresia dibandingkan dengan kontrol (P<0,05). Kesimpulan penelitian adalah ekstrak etanol daun pepaya Calina dosis 300 mg/Kg BB berpotensi menjadi agen antifertilitas alami dengan cara menurunkan GSI dan perkembangan ovarium tikus Wistar.

Published: January 2023

Zeolit adalah mineral aluminosilika berpori mikro sehingga memiliki permukaan yang luas. Permukaannya yang luas menyebabkan zeolit umum digunakan sebagai adsorben. Zeolit X termasuk dalam struktur Faujasit dan biasa mengikat kation natrium. Kation yang terikat pada zeolit dapat ditukar dengan kation lainnya, seperti kation logam transisi. Kation logam transisi seperti [Ag(NH3)2]+ biasa digunakan sebagai pendeteksi gugus aldehida atau biasa dikenal sebagai pereaksi Tollens. Penelitian ini bertujuan menyintesis komposit adsorben zeolit X/oksida perak dan zeolit X/oksida tembaga melalui reaksi Tollens. Komposit dikarakterisasi menggunakan scanning electron microscope menunjukkan permukaan milik komposit lebih kasar dari pada permukaan zeolit X. Bahan yang digunakan sebagai model untuk adsorpsi ialah, gas amonia. Komposit yang dihasilkan ada tiga jenis berdasarkan tahapan penambahan zeolit pada proses sintesis, yaitu setelah penambahan prekursor (komposit 1), setelah penambahan NH4OH (komposit 2), dan setelah pemanasan (komposit 3). Komposit yang dihasilkan mampu meningkatkan adsorpsi amonia hingga 2 kali lipat daripada zeolit X.
