Published: February 2023

Proses pembuatan kerupuk kulit yang dilakukan melalui empat tahap penggorengan memberikan efek kandungan minyak yang tinggi pada produk. Hal ini menjadi kendala tersendiri bagi para pelaku usaha pembuatan kerupuk kulit. Kandungan minyak yang tinggi dapat menyebabkan ketengikan pada produk dan membutuhkan waktu yang lama untuk proses penirisan minyak pada proses produksi. Mitra IKM “Rizky” yang memproduksi kerupuk kulit di Lubuk Buaya, Kota Padang masih menggunakan proses penirisan secara manual pada setiap tahap penggorengan. Tujuan dari kegiatan ini adalah penerapan mesin peniris minyak (spinner) pada proses pembuatan kerupuk kulit di Mitra IKM “Rizky” untuk meningkatkan efisiensi produksi dan kualitas dari produk kerupuk kulit. Metode kegiatan dalam kegiatan ini dilakukan dengan pemberian mesin peniris minyak semi-otomatis diikuti dengan pelatihan dan pendampingan dalam menggunakan mesin peniris minyak serta mempraktekkan mulai dari penggorengan tahap pertama hingga tahap terakhir dalam pembuatan kerupuk kulit. Hasil dari kegiatan ini adalah penggunaan mesin peniris minyak dapat mengurangi waktu proses penirisan minyak dari 3,5 jam menjadi 15 menit tanpa memberikan efek kerusakan pada produk. Selain itu, penggunaan mesin peniris minyak memberikan hasil penirisan minyak yang lebih optimal dibandingkan dengan cara penirisan manual. Kandungan minyak pada kerupuk kulit menjadi lebih kecil sehingga bisa mengurangi potensi terjadinya ketengikan pada produk. Kesimpulan dari kegiatan ini adalah penggunaan mesin peniris minyak pada proses produksi kerupuk kulit di Mitra IKM dapat meningkatkan efisiensi produksi dan meingkatkan kualitas dari produk kerupuk kulit.

Teniendo en cuenta la amplia difusión que ha tenido la analítica de datos en diferentes ámbitos de aplicación y considerando los escases de datasets específicos asociados a los delitos informáticos dentro de las estrategias de datos abiertos en Colombia, este artículo tiene como objetivo realizar la caracterización de los delitos informáticos del departamento de Cundinamarca, mediante el uso de técnicas de análisis exploratorio y machine learning. La presente investigación fue desarrollada mediante 4 fases metodológicas: adecuación de los datos, análisis exploratorio de los datos, aplicación de modelos de machine learning y finalmente generación de información de valor agregado. Para el desarrollo del estudio propuesto, se conformó un conjunto de datos a partir del dataset de 35000 registros publicado por la Policía Nacional en el portal de datos abiertos de Colombia, el cual aborda los delitos de alto impacto dentro del departamento de Cundinamarca y ocurridos durante el primer semestre de 2021. El dataset de delitos cibernéticos conformado cuenta con un total de 1513 registros e incluye atributos tales como: día, trimestre, municipio, zona, victima, edad y delito, de tal modo que a nivel del análisis exploratorio se aplicaron métodos de estadística descriptiva sobre los diferentes atributos, mientras que a nivel de machine learning se hizo uso de los modelos de reglas de asociación y clustering con el fin de determinar de manera respectiva la relación de los atributos con el tipo de delito, y los grupos representativos que se forman al relacionar la edad con el tipo de delito y el municipio con el tipo de delito. El estudio desarrollado permitió demostrar la utilidad y potencialidad que tienen las técnicas de analítica de datos en el campo de la ciberseguridad, de cara a apoyar la toma de decisiones por parte de las autoridades pertinentes.
Desafíos y oportunidades de la Vinaza de caña de azúcar. Un análisis bibliométrico.
Authors: Ospina León Lina Julieth , Manotas-Duque Diego , Ramirez Malule Howard Diego
Published: February 2023

La vinaza de caña de azúcar (VC) es el principal subproducto de la producción de bioetanol. Esta se considera un potencial contaminante debido a su índice de acidez y a la presencia de componentes orgánicos, sólidos en suspensión y metales pesados. Los altos niveles de producción de VC son sin duda una amenaza para el ambiente y la comunidad en general. El objetivo de este estudio fue evaluar las principales disposiciones o tratamientos de VC, además de sus aplicaciones, empleando mapas bibliométricos para el análisis de metadatos. Se encontró que los principales focos de estudio con relación a la VC son: (i) digestión anaeróbica (DA), (ii) fertirrigación, (iii) coagulación/floculación, (iv) algas, microalgas y hongos, y (v) producción de hidrógeno. Adicionalmente, se determinó que el tratamiento más efectivo para VC fue la DA, alcanzando una eficiencia de 90% en la remoción de demanda química de oxígeno y una recuperación energética entre 85 y 95% como biogás. Finalmente, se abordaron los desafíos y oportunidades que enfrenta Latinoamérica con la creciente producción de VC, así como una revisión detallada de su tratamiento y/o disposición, incluyendo condiciones óptimas para la producción de productos de valor agregado.

Authors: Saavedra Robinson Luis Andrés , Quintero Camila , Pulido Velasco Juan Andres
Published: February 2023

La problemática en la producción artesanal de ladrillos en Colombia es diversa y se pueden apreciar criterios ambientales, técnicos, económicos y sociales que influyen sobre el desarrollo de esta actividad económica. Para ello, se realizó una exploración de las tecnologías de horno de ladrillos existentes mediante un análisis jerárquico de procesos, un estudio de ergonomía física, un estudio relacionado a la localización y distribución de la instalación y finalmente, una simulación del proceso productivo para generar el diseño de una nueva planta de producción que favorezca la organización productiva del sector contribuyendo a la reducción de emisiones contaminantes y mejore las condiciones laborales de los trabajadores. La simulación ha arrojado que la nueva planta estará en capacidad de fabricar 55 lotes de 12 mil ladrillos al año con ingresos anuales superiores a COP$264.000.000.
Más allá de Judith Butler: reflexiones sobre “El género en disputa. Feminismo y subversión de la identidad”
Authors: Guerra Zabala Victor Daniel , Fernández Moreno Sara Yaneth
Published: February 2023

Judith Butler es una filósofa con una creciente importancia en los estudios de género. Su obra “El Género en disputa. Feminismo y subversión de la identidad” (1990) es uno de los textos pioneros de la teoría de la performatividad y de los movimientos queer. Con una fuerte influencia del pensamiento de Gayle Rubín, Monique Wittig, Merleau-Ponty, Jacques Lacan, Simone de Beauvoir, Michael Foucault, Jacques Derrida y Friedrich Nietzsche, Judith Butler, parte de una crítica a la metafísica de la sustancia y a los hábitos académicos de reificación social presentes en las categorías de sexo, género y cuerpo. Este trabajo pretende ir más allá de Judith Butler, buscando generar mayores claridades conceptuales a jóvenes lectoras y lectores de su teoría. Entre sus conclusiones más relevantes destaca, en primer lugar, que el sexo es una construcción que se legitima ante la ley por causa de su aparente “naturalidad”, en segundo lugar, que el género es un acto performativo sostenido culturalmente e individualizado en cada ingreso subjetivo a la cultura. Su obra resulta ser una invitación importante a vivir una época y un paradigma académico y político diferente.

En las conclusiones se presentan estos ejes en conjunto y se plantea que pueden comprenderse a partir de tres tipos de interpelación: interpelación técnica, interpelación punitivista e interpelación emocional.
Comprender lo desconocido
Authors: Zunino Gabriela Mariel
Published: February 2023

La comprensión de oraciones y textos involucra fenómenos complejos en los que interviene tanto información específicamente lingüística como información extralingüística. Analizamos aquí cómo incide la ausencia de conocimiento previo sobre el mundo durante la comprensión de oraciones y, específicamente, si este factor modula el proceso en función del tipo de relación semántica: aditiva, temporal y causal. A partir de una tarea de comprensión de oraciones bajo un paradigma de lectura a ritmo propio, revisamos la Hipótesis de causalidad por defecto. Se registraron los tiempos de lectura y la precisión de respuesta a preguntas de comprensión. Los resultados muestran un efecto principal generado por la imposibilidad de involucrar conocimientos previos sobre el mundo e interacciones vinculadas con el tipo de relación semántica. Se exhibe una centralidad del eje temporo-causal también para la comprensión de información desconocida, aunque no todas las predicciones hechas por la Hipótesis de causalidad por defecto se sostienen para estos casos.

Educación de la infancia en contextos de violencia sociopolítica: una perspectiva desde la voz de mujeres líderes comunitarias de Yumbo, Colombia
Authors: Escobar-Arias Diana Morela , Molina-Mora Guiomar Patricia
Published: February 2023

Uno de los desafíos que tiene el gobierno colombiano es la construcción de una paz estable y duradera para los próximos años. Para su logro es indispensable la participación de los diferentes colectivos sociales que han sido protagonistas de la violencia social y política que por más de cinco décadas ha afectado al país. Por otro lado, la educación de la infancia es un derecho que está siendo vulnerado por las situaciones de violencia que aún presentan las comunidades locales. En el marco de esta situación el siguiente artículo recoge el análisis que 19 mujeres líderes comunitarias del municipio de Yumbo, Colombia, lograron hacer sobre la educación de la niñez en contextos de violencia sociopolítica, reconstruido a través de la aplicación de cuestionario y entrevistas semiestructuradas, en el marco de una investigación de tipo descriptivo-exploratoria. Las líderes comunitarias se consideran como actoras claves en el análisis de esta problemática, gracias a su trayectoria en los procesos comunitarios de sus barrios. Desde este lugar ellas construyen un balance de las acciones u omisiones de la familia, la escuela, el gobierno local y de otras organizaciones frente a la infancia y realizan propuestas que, desde su perspectiva, pueden contribuir al bienestar de la infancia de tal manera que los impactos de la violencia sean menores.
Problematizaciones de roles de género y estereotipos de belleza a través de cuentas de Instagram durante la pandemia en Colombia
Authors: Muñoz-Zapata Doris Elena , Estrada-Jaramillo Lina Marcela , Osorio-Franco Johanna Marcela
Published: February 2023

Este trabajo presenta una investigación cualitativa utilizando el análisis de discurso y la etnografía digital de contenidos publicados en las cuentas de Instagram @lainsumisa y @feministasenconstrucción, durante el primer año de la pandemia en Colombia (entre marzo de 2020 y marzo de 2021). Estas cuentas apuestan por la perspectiva de género y el respeto de los derechos de las mujeres. La investigación destaca que las redes sociales digitales posibilitan la propagación de estereotipos de belleza y roles de género y facilitan el surgimiento de colectivos, comunidades y redes de apoyo de mujeres que luchan por la equidad de género y sus derechos. Se concluye que en escenarios sociales físicos como digitales hay posturas, ideas y opiniones diversas, y la necesidad de educar a las mujeres desde el camino del amor por sí mismas. La importancia de este trabajo radica en el aporte de miradas alternativas, solidarias y esperanzadoras frente a los roles actuales.
Identificación de elementos asociados a la exclusión en relatos autobiográficos de docentes en formación inicial en Bogotá D.C., Colombia
Authors: Aragón-Barreto Miguel Ángel
Published: February 2023

El proyecto Pedagogía de la compasión y la ternura para la inclusión en el aula, desarrollado entre los años 2019 y 2020, en la Universidad Distrital Francisco José de Caldas, de Bogotá D.C., Colombia, se ejecutó con el objetivo de fomentar la compasión y la ternura como capacidades relevantes en la formación inicial de docentes. Para lograrlo, se propuso reconocer inicialmente el fenómeno de la exclusión social, como elemento transversal en la vida de los educandos. La propuesta fue desarrollada en el marco de una investigación de corte cualitativo, mediante el método etnográfico, utilizando el análisis de narraciones de los estudiantes y observación participante. Con la investigación, fue posible examinar procesos de exclusión atravesados por un entramado de causas, actores, contextos, emociones y consecuencias particulares, permitiendo a 19 participantes identificarse como sujetos excluidos y excluyentes al mismo tiempo. Se evidenciaron los contextos de la familia y la escuela como los principales espacios donde se lleva a cabo la exclusión y donde se presentaron actos de exclusión crueles y violentos que impactaron directamente en la personalidad de los docentes en formación; además, se evidenció un tipo de “auto-exclusión” que podría ser necesaria, como respuesta a otros actos de exclusión.

Authors: Rodríguez-Venegas Viviana , Duarte Hidalgo Cory
Published: February 2023

En octubre de 2019, Chile vivió un proceso de intensas movilizaciones sociales en todo su territorio, un estallido social que se extendió hasta el inicio de las primeras restricciones por la pandemia. En ese marco, se realiza un estudio cualitativo que pretende develar narrativas desde múltiples matices y visiones que permiten re-vivir lo vivido, para así comprender las resistencias, ilusiones, demandas y luchas en pleno proceso de protestas sociales en Chile. La investigación utiliza un diseño narrativo bajo la modalidad de entrevistas a distancia, a través de Whastapp, pesquisadas entre los meses de noviembre y diciembre de 2019. Los principales resultados arrojan la sorprendente masividad, rabia acumulada y (des)ilusiones ciudadanas, así como la necesidad de cambios profundos, demandas históricas y resistencias desde un plano emotivo y afectivo. Lo novedoso del estudio es que presenta una mirada desde las propias voces ciudadanas en distintos territorios en el contexto inmediato del estallido social.
Problems of the Formation of the Industrial Potential of Pridnestrovie as Part of Molodavia (1940 – 1941)
Authors: Kulbidiuk Ruslan Viktorovich
Published: February 2023

The author discusses the first steps of the Soviet government to restore and create the industrial complex of Moldovia after the liberation of the right-bank regions of Moldavia – Bessarabia - from the power of Royal Romania in the period from June 28, 1940 to June 1941. The purpose of the study is to characterize and evaluate the actions of central and local authorities in the first months after reunification on the nationalization of fixed assets and collectivization of agriculture, restoration, launch and establishment of industrial enterprises in the territory of the MSSR, as well as to identify the main directions of industrial development in the region during this period, the features of the formation of industrial potential taking into account the ongoing nationalization, the analysis of attracted resources and their characteristics, comparison with the industry of Royal Romania. The author presents an analysis of the main activities of local authorities on nationalization, as well as identifies the main financial sources allocated for the development of industry. The initial economic and cultural level, from which the formation of a new way of life for the Moldovan people began, after the reunification of the population of Bessarabia with the population of Transnistria (MASSR), is analyzed. The conducted research allowed us to conclude that it was the help of the peoples of the USSR that allowed the population of the republic to eliminate inequality in economic, political, cultural and other areas of life in a historically short period of time. According to the results of the study, the fundamental role of Pridnestrovie (MASSR), on whose socio-political and economic basis the reunited Soviet Moldavia was formed, also became obvious. The diverse production base created earlier in Pridnestrovie (MASSR) from scratch, together with thousands of trained highly qualified workers, provided invaluable assistance in the state, economic and cultural revival of Bessarabia. The study used such methods of historical research as retrospective analysis, comparative analysis, as well as a systematic approach and the method of expert assessments.
The Impact of World War II on the Status of European Monarchies
Authors: Shchegolikhina Svetlana Nikolaevna
Published: February 2023

World wars were the key moments that had a significant impact on the transformation of monarchical rule in the twentieth century. They served as catalysts in the process of changing the European political system, determining the direction of development. The subject of the study are the European monarchies. The object of the study is the transformation of the traditional form of government in the countries of Europe. Using the historical-anthropological method, as well as historical-systemic and historical-comparative approaches, the question of general and special in the process of transformation of monarchical rule in the middle of the twentieth century is considered. The author focuses on the question - Is the tendency of monarchies to leave the historical scene objective, colored by national peculiarities, or depends on the specific situation and the particular ruler? After World War I, the revision of government affected all parts of the world. The Second World War was a new challenge to the historic system of governance. As a result, the transformation of centuries-old interaction between the state and society has become irreversible. It has institutionalized democratic royalism as the main social and political perception of traditional forms of government. Only as long as the monarch follows the established rules will the monarchy exist. It has lost most of its key characteristics, remaining only a historical and cultural symbol - without real power or significance for political and social life, depending on social and political sentiments.
Quality assurance for non-contrast CT of the abdomen and pelvis during a period of supply chain disruption leading to iodinated contrast shortage in the emergency department setting
Authors: Calimano-Ramirez Luis Fernando , Hernandez Mauricio , Singh Anmol , Gumus Kazim Ziya , Marfori Wanda , Virarkar Mayur K. , Lall Chandana , Gopireddy Dheeraj Reddy
Published: February 2023

Objectives:

Iodinated contrast media (ICM) shortage crisis due to COVID-19 lockdowns led to a need for alternate imaging protocols consisting of non-contrast computed tomography (CT) for abdominal complaints and related trauma indications in emergency department (ED) settings. This quality assurance study aims to evaluate clinical outcomes of protocol modifications during ICM shortage and identify potential imaging misdiagnosis of acute abdominal complaints and related trauma.

Material and Methods:

The study included 424 ED patients with abdominal pain, falls, or motor vehicle collision (MVC)-related trauma who had non-contrast CT of the abdomen and pelvis in May 2022. We accessed the initial complaint, order indication, non-contrast CT results, any acute or incidental findings, and any follow-up imaging of the same body region with their results. We evaluated their association utilizing Chi-squared tests. We assessed sensitivity, specificity, and positive/negative predictive values using follow-up scan confirmation.

Results:

Across initial complaint categories, 72.9% of cases were abdominal pain, and 37.3% received positive findings. Only 22.6% of patients had follow-up imaging. Most confirmed original reports were for abdominal pain. We also found three reports of missed findings. There were significant associations between complaint categories and initial non-contrast CT report results (P < 0.001), as well as initial complaint categories and whether the patient received follow-up imaging or not (P < 0.004). No significant associations were found between follow-up imaging results and initial report confirmation. Non-contrast CT had 94% sensitivity and 100% specificity, with positive and negative predictive values 100% and 94%, respectively.

Conclusion:

Rate of missed acute diagnoses using non-contrast CT for patients presenting to the ED with acute abdominal complaints or related trauma has been low during the recent shortage, but further investigation would be needed to verify and quantify the implications of not routinely giving oral or intravenous contrast in the ED.

Published: February 2023

Penelitian ini bertujuan menganalisis politik lingkungan hidup yang terdapat di Madura. Fokus utamanya yaitu permasalahan sistem irigasi yang dikelola Panembahan dan Residen yang pada akhirnya menjadi konflik tersendiri dalam pusaran pemerintahan di Madura. Konflik ini sebenarnya akibat pengambilalihan kekuasaan penguasa lokal seperti kerajaan Bangkalan, Pamekasan dan Sumenep yang oleh Belanda sejak 1850-an terjadi sebuah peralihan sistem pemerintahan yang mengelola hajat hidup masyarakat di Madura. Dalam perkembangannya banyak terjadi berbagai perlawanan yang diinisiasi para Panembahan bersama dengan rakyat Madura dengan melakukan perlawanan dalam pembangunan irigasi yang dibangun oleh Residen di Madura. Hal ini tentu menjadi fenomena yang langka pada masa kolonial. Di satu sisi mereka membutuhkan irigasi untuk kebutuhan pokok serta mengairi sawah. Di sisi lain, sebagian dari masyarakat Madura mencoba untuk menghancurkannya. Penelitian ini menggunakan metode sejarah yang terdiri heuristik, kritik, interpretasi dan historiografi. Beberapa data di dapatkan dari Arsip Nasional Republik Indonesia, Perpustakaan Nasional Republik Indonesia dan media online yang terpercaya seperti delpher.nl dan Gahetna. Sumber yang didapatkan berupa arsip dan manuskrip. Hasil penelitian menunjukkan dinamika konflik antara Panembahan dan Residen diawali oleh pengambilalihan kekuasaan lokal oleh pemerintah kolonial sehingga menimbulkan kepentingan kekuasaan yang cukup berlawanan antara keduanya. Adapun konflik tersebut mengakibatkan kerusakan lingkungan di Madura.
Climate Change Impacts on Forests and the Livelihoods of Tribal People of Northeast India
Authors: Sarma Kiranmay , Kalita Kamaleswar
Published: February 2023

The degradation of forest lands has severe impacts on the environment and livelihoods of the people including health and socio-economic condition. One of the main drivers of forest degradation is slash-and-burn agriculture practiced traditionally in the hills of tropics and it accounts 60 percent global forest loss every year. In northeast India, this method of agriculture is practiced extensively and about 0.45 million families are involved in this activity. The forest area covered annually by this cultivation is about 10,000 km2. At present in northeast, the estimated land under shifting cultivation or jhum is estimated to be 44,000 km2. Loss of forests due to shifting cultivation has caused many problems ranging from floods to aridity and catastrophic losses to water quality. Besides, burnt practices of biomass release GHG (greenhouse gases) and this could play significant role for climate vulnerability in the region like northeast. Climate vulnerability significantly affects the traditional matriarchal society in many parts of tribal areas, socio-economic and ecological conditions, health and the livelihoods. In all these aspects, women are the most sufferers and vulnerable. The increasing numbers of flash floods in this region destroy the standing crops and damage the down slope areas with the debris carried by the flood water. This becomes a regular event during the rainy seasons. The rich customs and traditions of the tribal people help to develop some innovative strategies using locally available resources to overcome this type of unwanted situations.
An Operational Framework Model for Geospatial Business Impact Analysis in West Coast of Sabah, Malaysia
Authors: Lehan Nur Fadzlina Aini M. , Razak Khamarrul Azahari , Kamarudin Khairul Hisyam
Published: February 2023

Population expansion and rapid urbanisation rate coupled with extreme changes of weather conditions have triggered more frequent disaster occurrences resulting in bigger economic and commercial losses. Like many other economic sectors that contributed significantly towards local socio-economic development, the small and medium enterprises (SMEs) also were not spared from being affected and/or disrupted by disaster events. In 2020, SMEs in Malaysia represented 98.5% of local business establishments and contributed approximately 41% to the country’s GDP. Although Malaysia can be considered a relatively safe and stable country from a political and socio-economic tussle, as a country with tropical climate, Malaysia, is highly vulnerable to the risk of flooding, landslide and mudslide which jeopardise the sustainability of local SMEs in the long run. Unfortunately, until today, there is no locallydriven comprehensive framework for promoting SMEs resiliency that has been developed particularly in disaster-prone areas. In this light, advanced geospatial technology that has been widely used in mapping for various purposes can be utilized or integrated into mapping of disaster risk profiles and providing significant inputs for establishing Business Continuity Planning (BCP) for disaster-prone areas. Using business impact analysis (BIA) approach, this study explains the operational framework model for business continuity and recovery. The case study of local SMEs in West Coast Sabah, Malaysia was adopted to explain the impacts of the 2015 earthquake and its cascading geohazards to local SMEs including severe disruptions to the main lifeline facilities e.g. telecommunication, electricity and transportation. The research design is based on the qualitative and quantitative methods including guided interviews with the affected local SMEs groups. The proposed operational framework is a result of integrated smart geospatial solutions for advancing business continuity and resiliency for SMEs in disasterprone areas.

Published: February 2023

Disaster Risk Reduction (DRR) is one of the prioritized activities worldwide including Indonesia. To fulfill DRR in Indonesia, the National Board for Disaster Management (BNPB) issued a BNPB Head Regulation Policy No. 1 of 2012 for the general guidelines for Disaster Resilient village/sub-districts (Destana). This program aims to increase the village/sub-district’s capacity in DRR when faced with disaster. This study uses a descriptive research method with a qualitative approach. The data was collected through interviews and field observations in Sitiarjo Village, Malang Regency, East Java Province, Indonesia. This study found that the Malang Regional Disaster Management Agency (BPBD) has attempted to carry out capacity building on the dimensions of human resource, organizational strengthening and institutional reform in Sitiarjo Village through training and socialization provided by the Malang Regency BPBD and other stakeholders in the DRR Program in Sitiarjo Village. Organizational strengthening has also been carried out in Sitiarjo Village, where the Sitarjo Village Disaster Risk Reduction Forum (FPRB) has been established before Sitiarjo Village was incorporated in the Destana program and has cooperated with other stakeholders in capacity building in Sitiarjo Village. However, the institutional reform at Sitiarjo Village Destana has not run optimally as the Government has not made a policy in village/sub-district regulations specialized in the Destana program in Sitiarjo village. The main problem is the lack of community participation in capacity building carried out by Malang’s BPBD. The community perceives that capacity building in the Disaster Resilient Village/subdistricts Program (Destana) is more about meeting DRR needs. It requires an understanding of DRR and the necessary capacity building that follows the characteristics of each village/sub-district. With high awareness among all DRR Program stakeholders, each village/sub-district’s independence in dealing with threats and disaster risks can be properly realized.

Effective management system, high competitiveness and investment attractiveness of the enterprise ensure effective development of any enterprise. It is also noted that one of the ways to effectively search for directions for the development of the enterprise management system is the use of managerial diagnostics in the management system, taking into account the diagnostics of the effectiveness of the organizational structure of the enterprise management. It has been determined that today a relevant and important issue is the need to form new and improve existing provisions (both theoretical and practical) regarding the effectiveness of the organizational structure of enterprise management under risk conditions, using mathematical modeling. In view of this, the purpose of the study is to develop an economic-mathematical model for diagnosing the effectiveness of the organizational structure of enterprise management under risk conditions. Based on the results of the research, in the article proposes a new economic-mathematical model and, on its basis, optimization criteria and ratios are formed, that ensure the effective functioning and development of the enterprise, taking into account the characteristics, role and importance of the effectiveness of the organizational structure of enterprise management under risk conditions.

Airborne microorganisms have potential to cause infections and respiratory diseases like asthma. It is necessary to reduce the human exposure to such pathogens. This study was based on the determination of indoor environmental quality and the quantification of microbial load in a university premises in Karachi, Pakistan. Seven different locations with high human occupancy during office hours were sample din winter and summer. Culturable microorganisms i.e. bacteria and fungi were collected on selective media by Spin Air V2 sampler. The average bacteria and fungi concentration sin winter were133 ± 26colony forming unit per cubic meter (CFU.m-3) and 199 ± 59 CFU.m-3 respectively. In summer counts were higher than winter with bacterial and fungal count of 205 ± 39 and 306 ± 102 CFU.m-3. There was strong correlation (r = 0.8, p = 0.032) between fungal count and humidity, and between bacterial and fungal count (r = 0.802, p = 0.030). The most common culturable airborne fungi in both seasons were Aspergillus, Penicillium, Cladosporium, Fusarium, Alternaria, Stachybotrys, Candida, and Rhodoturola. Resultsindicate that the indoor environment in university premises harbours high concentrations of microorganism and needs regular indoor air quality monitoring and establish local guidelines to prevent diseases.
Complexities of the interaction of Ni(II), Pd(II) and Pt(II) pyrrole-imine chelates with human serum albumin

Human serum albumin (HSA) efficiently transports drugs in vivo: most are organic. Here, HSA binding affinity and site specificity are shown to depend on the identity of the d8 metal ion in Ni(II), Pd(II) and Pt(II) chelates of the bis(pyrrole-imine) ligand H2PrPyrr. Fluorescence quenching data for native and probe-bound HSA showed sites close to Trp-214 (subdomain IIA) are targeted. The Stern-Volmer constants, KSV, ranged from 10^4 M^(-1) to 10^5 M^(-1) while the affinity constants, Ka, ranged from 3.5 x 10^3 M^(-1) to 1 x 10^6 M^(-1) at 37 degrees Centigrade, following the order Pd(PrPyrr) > Pt(PrPyrr) > Ni(PrPyrr) > H2PrPyrr. Ligand uptake is enthalpically driven, hinging mainly on London dispersion forces. Induced CD spectra for the protein-bound ligands could be simulated by hybrid QM:MM TD-DFT methods, proving that the metal chelates neither decompose nor demetallate after uptake by HSA. Transport and delivery of the metal chelates by HSA in vivo could therefore be feasible.

Clean energy, as well as air and water pollution, have become key challenges in today's society. Photocatalysis could be one of the ways to address them. It is considered as an advanced oxidation method that involves light to activate a semiconductor. Semiconductors based on titanium dioxide (TiO2) are widely regarded as photocatalytically active materials. However, the performance of TiO2 has limitations due to its wide band gap (~3.2 eV), and a high recombination rate of the photo-generated electron-hole (e−−h+) pair. To overcome these drawbacks, TiO2 in heterojunction with tungsten trioxide (WO3) is well recognized as one of the most explored systems for photocatalytic applications. Depending on the synthesis technique, and the photocatalytic application, various yet contrasting behaviour can be found in the literature. In this work, the photocatalytic properties of the TiO2/WO3 system were thoroughly examined in the removal of gaseous benzene, and generation of H2. Graphene nanoplatelets were included into the TiO2/WO3 system to increase transport and life-time of the photo-generated exciton. The investigation of various parameters that affected the photocatalytic activity of synthesised materials were carried out, including the ratio of WO3 to TiO2, the presence of graphene, and the nature of the photocatalytic application. It has been observed that the position of the conduction bands played indeed a key-role in case of hydrogen generation. A type II heterojunction was found in the TiO2/WO3 system. Modification of TiO2/WO3 with graphene nanoplatelets improved the photocatalytic hydrogen generation, which was particularly evident in samples with higher WO3 content. The most significant increase in hydrogen production was observed with the photocatalyst with 15 mol% WO3 and 1 wt% graphene − a five-fold increase in yield, compared to its counter-part with no graphene.

Using amylin(2029) as a model system, we demonstrate that experimental constraints measured by Raman spectroscopy can be used to determine the molecular structure of amyloid fibrils. We employ both polarized and non-polarized Raman spectroscopy measurements to determine the distributions of peptide backbone amide C=O and CN bond orientations, as well as Ramachandran ψ dihedral angles, adopted by amylin(20−29) fibrils. We then use these experimentally measured distributions as structural constraints to guide molecular dynamics (MD) simulations of an amylin(20−29) fibril structure. The resulting structure indicates that amylin(20−29) fibrils adopt a antiparallel β-sheet architecture in excellent agreement with previous studies. Overall, these results demonstrate that Raman spectroscopy provides the ability to determine the three-dimensional molecular structure of amyloid fibrils in a manner that complements gold standard techniques such as solid-state NMR.

Before big data methods like machine learning and artificial intelligence methods can be used in chemistry, the digitization of chemistry and materials requires the development of a universal standard that is both affordable and broadly applicable. This has parallels with the foundations of the digital revolution which required standard architectures with a well-defined specification. Recently, we have developed automated platforms for the chemical artificial intelligence driven discovery, synthesis of molecules, materials, nanomaterials, and formulations. To avoid the use of highly expensive systems we focussed on the design and construction of standard hardware and software modules creating a road map for the digitization of chemistry across different fields. Our platforms can be divided into four different categories depending on their application: i) discovery systems for the search of chemical space and new reactivity, ii) synthesis and manufacture of fine chemicals, iii) formulation discovery and exploration, and iv) materials discovery and synthesis. We describe the evolution and convergence of these platforms in terms of, common hardware, firmware, and software along with the development of a programming language for chemical and material systems. This programming approach is not only useful for reliable synthesis, but for design of experiments, discovery, optimisation and providing new standards for collaboration. This approach is also vital for the verification of findings published in the literature, databases, to increase the reliability of experimental outcomes, and to allow collaboration across different research laboratory settings as well as the sharing of failed experiments.

Photo-assisted catalysis using Ni complexes is an emerging field for cross-coupling reactions in organic synthesis. However, the mechanism by which light enables and enhances reactivity of these complexes often remains elusive. Although optical techniques have been widely used to study the ground and excited states of photocatalysts, they lack the specificity to interrogate the electronic and structural changes at specific atoms. Herein we report metal-specific studies using static and transient Ni L- and K-edge X-ray absorption spectroscopy of a prototypical Ni photocatalyst, (dtbbpy)Ni(o-tol)Cl (dtb = 4,4-di-tert-butyl, o-tol = ortho-tolyl). We discovered that the ground state of this complex has a mixed-spin character of ~70/30% singlet/triplet. Furthermore, we confirm that the long-lived (~5 ns) excited state is a tetrahedral metal-centered triplet state. These results pave the way for the future design of Ni-bipyridine based photocatalysts by, for example, judiciously tuning the electronic and geometric properties of the ligands with the goal of increasing excited-state lifetimes and quantum yields of reactive species.

Fluorescent single wall carbon nanotubes (SWCNTs) are used as nanoscale biosensors in diverse applications. Selectivity is built in by non-covalent functionalization with polymers such as DNA. In general, fluorescence sensing with SWCNTs would benefit from covalent DNA-conjugation but it is not known how changes in conformational flexibility and photophysics affect the sensing mechanism. Recently, covalent functionalization was demonstrated by conjugating guanine bases of adsorbed DNA to the SWCNT surface as guanine quantum defects (g-defects). Here, we create guanine defects in (GT)10 coated SWCNTs (Gd-SWCNTs) and explore how this affects molecular sensing. We vary the defect densities, which shifts the E11 fluorescence emission by 55 nm to max = 1049 nm for the highest defect density. Furthermore, the difference between absorption maximum and emission maximum (Stokes shift) increases with increasing defect density by 0.87 nm per nm of absorption shift and up to 27 nm in total. Gd-SWCNTs represent sensitive sensors and increase their fluorescence >70 % in response to the important neurotransmitter dopamine and decrease 93 % in response to riboflavin. Additionally, cellular uptake of Gd-SWCNTs decreases. These results show how physiochemical properties alter with guanine defects and that Gd-SWCNTs constitute a versatile optical biosensor platform.
