Background: Behcet’s disease (BD) is a vasculitis with multisystem and multiorgan involvement. Cardiac involvement in BD is a rare complication with a poor outcome that manifests itself in different forms. In this study, we aimed to investigate cardiac involvement in BD. 
Methods: This is a retrospective study based on cardiac manifestations in BD according to the data of the Behçet’s Disease Unit, the Rheumatology Research Center, Tehran University of Medical Sciences, from registered patients from 1975 until June 2017. Cardiac manifestations consisted of pericarditis, myocardiopathy, myocardial infarction, stable ischemic heart disease, endomyocardial fibrosis, thrombosis, and valvular and coronary involvement. All the patients’ baseline and demographic data were recorded in a designed questionnaire. The laboratory workups, imaging, and pathological tests were also performed.     
Results: We studied 7650 patients with BD, of whom 51% were male. In the entire study population, 47 patients manifested cardiac involvement: valvular involvement in 6.1%, myocardial infarction in 23.4%, stable ischemic heart disease in 20%, pericarditis in 21.3%, intracardiac thrombosis in 2.1%, coronary aneurysm in 2.1%, heart failure in 12.8%, and dilated cardiomyopathy in 4.3%.
Conclusion: The prevalence of cardiac involvement in our patients with BD was 0.6%. A multidisciplinary approach can reduce mortality and morbidity rates. Consequently, we suggest that echocardiography and other cardiac diagnostic tests be routinely considered for early diagnosis and subsequent treatment.

Published: January 2022

Background: The discharge of uncomplicated patients with ST-segment-elevation myocardial infarction (STEMI) within 48 to 72 hours has been proven safe and feasible. The safety and feasibility of the very early discharge (≤48 h) of such patients, especially during the COVID-19 pandemic with limited bed availability and infection risk, have yet to be evaluated.
Methods:  In this cohort study on 108 patients with STEMI who presented to Farshchian Heart Center between February and May 2020, 30 patients received fibrinolysis and 78 were scheduled for emergent coronary angiography. One patient had no coronary obstruction, 3 underwent emergent surgery, and 3 had high-risk features mandating a prolonged stay. The remaining patients were assigned to either Group A (≤48 h) or Group B (>48 h) regarding hospital discharge. Demographic, angiographic, procedural, and outcome data were compared between the 2 groups.
Results: Group A consisted of 51 patients, including 7 women (13.7%), at a mean age of 62.74±12.35 years, and Group B comprised 20 patients, including 4 women (20.0%), at a mean age of 65.20±12.82 years. The mean hospital length of stay was 38.02±9.15 hours in Group A and 88.20±23.31 hours in Group B (P<0.001). The mean stent diameter was smaller in Group B (3.19±0.34 mm vs 2.96±0.29 mm; P=0.008). Demographic, angiographic, procedural, and outcome data, including the rates of in-hospital, 1-week, and 1-month mortality, were similar between the 2 groups.
Conclusion: This study shows that a hospital discharge in less than 48 hours in low-risk patients with STEMI is safe and feasible. The potential advantages of this approach in the COVID-19 pandemic should be balanced against its risks.

Introduction: The unique properties of nanomaterials, in addition to their applications in science and technology, can be a threat to human health and the environment. Exposure to these materials may occur in workplaces or research laboratories. It can be said that about half of people with occupational exposure to nanomaterials work in academic environments and laboratories. So, the present study was conducted to design and validate a tool to investigate the principles of working safely with nanomaterials in research laboratories.
Materials & Methods: The tool was designed using reports, instructions and articles related to " Methods of working safely with nanomaterials". The validity of the tool was assessed using Lawshe method by calculating CVI and CVR. The reliability of the instrument was evaluated using Cronbach's alpha coefficient and kappa coefficient.
Results: The tool was designed in 5 sections: "General Information", "Transportation and Storage of Nanomaterials", "Engineering Controls", "Administrative Controls" and "Personal Protection Equipment". After validation, 5 items did not get the necessary points to stay in the tool and were removed. The Cronbach's alpha value for each section of the tool was more than 0.80, indicating that the was "appropriate".
Conclusion: According to the results, it seems that the tool studied in this study is compatible for the designed purpose and is ready to be used as a questionnaire or checklist.

Published: January 2022

Introduction: Nowadays, counterproductive behaviors have become a common and costly position for many organizations, and Managers of organizations are always looking for a suitable and practical solution to reduce this type of behavior in their organization. Due to the importance of the subject, the present study aims to investigate the imbalance of effort and reward as a predictor of counterproductive behaviors.
Materials and Methods: The present study is a cross-sectional study. The target population was all nurses working in hospitals in Hamadan, and according to the simple random sampling method, 320 people were selected as the research sample. The tools used in this study were the Imbalance of Effort-Reward questionnaire and the counterproductive questionnaire. Data analysis was performed using the Pearson correlation method using SPSS18.
Results: The results showed that the effort-reward imbalance model at a significance level of 0.05 is able to predict individual counterproductive behaviors in nurses (P = 0.036). Among the studied variables, the reward variable is able to predict individual counterproductive behaviors (β = -0.179 and P = 0.006) and organizational (β=-0.171 and P = 0.009) and the over-commitment variable is able to predict individual counterproductive behaviors. (β= 0.145 and P = 0.05). According to the results, the effort-reward imbalance model could not predict organizational counterproductive behaviors.
Conclusion: Based on the results, it can be concluded that job stress is an important factor in creating Counterproductive behaviors in personnel and the components of the model used in this study can be used to reduce the incidence of these behaviors among nurses.

Purpose: In 2016 the Indian society was introduced with the regulation and development act for real eastate (RERA) to bring transparency in the dealing of real estate in terms of deals between developers and consumers taking into consideration the wellfare of the consumers. This research aims to identify and understand the extent of Arhitects role in the act focussing on punishments and arbitration for various offenses.

Methodology: An online survey was conducted with practicing architects to understand their perspective and viewpoints to identify what they feel are the biggest positives and negatives of the act.

Main Findings: The results show that 17% of the architects have faced disputes related to RERA and 60% of respondents were not satisfied with RERA's duration to resolve any of the cases, which were not resolved until the date. From the data gathered through the online survey, most of the respondents were unaware of their role they are required to perform as mentioned in the act.

Implications: To perform Architects' tasks correctly, awareness of the RERA, 2016 Act is necessary. The survey shows that many respondents thought that the act had nothing to do with architects and was solely for builders.

Published: January 2022

The study assessed expenditure on food among urban households in Benue State of Nigeria. This was done with the view to assess household food expenditure and its implications for food security status of the households; identify and assess determinants that influence household food demand; and analyze the determinants of food security of household urban population. The selection of the sample for the study involved a three-stage sampling technique. Data was collected from 150 households through a structured questionnaire. Descriptive statistics, food security index, multiple linear regression and logit regression were employed to analyze data. The results indicated a mean household expenditure on food that stands at N21,748.00 40.3 USD) per month. Based on the food security index the households that spent at least N14, 498.67 (93.5 USD) on food per month were categorized as food secure and those who spent below this value were categorized as food insecure. Furthermore, 67.3% of the households were food secure, while 32.7% were food insecure. The study revealed that size of household, income of the household head and price of food comodities were identified as major factors influencing household food demand decisions in the study area. Moreover, size of the household and income of the household head were the main determinants of food demand in the study area (F = 19.78; p ≤ 0.05) just as age and income of household head as well as household size influence the probability that a household will be food secure(χ2 = 13.77; p > 0.05). The study recommends that household heads should be educated on the need to control family size and to be self-empowered without necessarily depending on government as a way of enhancing their income to improve the household and economic conditions. The government should strengthen its policy on grain reserves in order to control food prices during scarcity and subsidize farm i nputs and availability to boost food production and thus lower food prices.
Household-food market relations and its implications for food security of farm families in Imo State Nigeria
Authors:   University of Ibadan, Nigeria, Olajide OA
Published: January 2022

The existence of markets is critical to the survival of the farm-household-family system and as such the nature of this relationship and how it affects the dietary supply of the household needs to be understood. The objective of this study is to examine the market relation of farm families by examining the degree of market orientation, the seasonal nature of market sales and purchases and their possible implications for food security. A total of 120 households were selected from the rural areas of Imo state using a multi-stage random sampling technique. The surveyed households were classified into Peri-Urban and Remote Farming Systems (PUFS and RFS) through a hierarchical clustering technique after the data were collected. Descriptive and comparative analyses were carried out using the Mann Whitney Test. The results showed that certain crops (cassava and yams) which command good prices and can yield high income were cultivated on a relatively large scale mainly for processing and consumption by the PUFS. The RFS on the other hand, did not have large outputs but sold about 40 percent of whatever they produced irrespective of its quantity in order to generate cash to meet other household needs. Farm families in the PUFS sold only 19 percent of their total output implying that they produced crops mainly for household consumption. It also showed that households in both systems had to buy food stuff from markets to meet household food supply needs at a period when they were likely to be cash strapped-the hungry season. As such, households compromised the quality of food stuff purchased during such difficult times; this was found to be particularly common in the RFS. At least 40 percent of households in both systems purchased and consumed broken or degraded items from the market during the hungry period. A seasonal intervention is required for short-term remedies while improving storage, processing and transportation facilities will in the long run improve market efficiency and give households better rewards in terms of income and purchased food prices.
Efficacy of cultural methods in the control of rhizoctonia solani strains causing tomato damping off in Kenya
Authors:   Karatina University College, Kenya, Muriungi SJ , Mutitu EW ,   University of Nairobi, Kabete Campus, Kenya, Muthomi JW
Published: January 2022

Rhizoctonia damping off of tomato caused by Rhizoctonia solani can be a serious problem in most intensive production environments. Recent increase in smallholder vegetable production of 0.5- 3.0 ha in Kenya has resulted in build up of the pathogen to above economic threshold levels. There is no effective chemical control or resistant varieties. Use of soil fumigants such as methyl bromide in the control of Rhizoctonia and other soil borne pathogens is not sustainable due to their high costs, and toxicity to ma n and environment. Cultural methods such as soil amendments, mode of planting and influencing soil moisture levels either alone or in combination with other methods are among the most likely substitute s to use of toxic fumigants for control of soil borne pathogens in agriculture. This study was undertaken to evaluate the effect s of cow manure application, transplanting , planting on raised beds and varying watering interval on Rhizoctonia damping off of tomato as measured by percent seedling survival at 5 -30 days after planting (DAP), disease severity at 30 DAP, percent crop stand at 60 DAP and fruit yield at maturity . The study was conducted in a field artificially inoculated with pathogenic strains of Rhizoctonia solani isolated from infected tomato plants and Rhizosphere soil sampled from the major production regions of Kenya. The efficacy of the various cultural strategies both singly and in combination on the Rhizoctonia damping off management was compared with the conventional disease control involving chemical fumigation with metham sodium and two chemical seed dressers (pencycuron, thiram, imidacloprid) and ( captafol) as the standard . Cow manure application and shorter watering interval when used singly or in combination with other cultural methods produced lower disease control and yield. Transplanting, planting on raised beds and medium irrigation interval when used singly or in combination with other cultural strategies produced good disease control resulting in higher yield that compared favorably with the conventional disease control involving soil fumigation and seed dressing. The various cultural disease control methods documented in this study can be used alone and in integration with other compatible Rhizoctonia damping off of tomato control strategies. Furthermore the promising non- chemical strategies may form part of the urgently sought for alternative to use of hazardous fumigants in agriculture and since they are not specific, there is low risk of resistant development over time.
Descriptive and consumer preference of omashikwa, traditional fermented buttermilk from Namibia
Authors:   University of Namibia, Bille PG
Published: January 2022

Omashikwa, traditional fermented buttermilk processed by the Owambo and Herero communities from the North and Central Namibia has become very popular among the local consumers . However, its sensory quality fluctuates from one household to the next due to poor hygiene, sanitation and the non- standardized traditional processing technologies . The raw milk from indigenous cows is fermented traditionally in calabashes without the addition of known starter cultures. Milk in the calabash is then stored in a warm place in the house for two to three days to ferment. Once it is fermented, it is shaken or agitated in the calabash for hours to churn into butter. Butter granules are removed and either made into butter or boiled to make Ghee or butter oil known as Omazeothung’ombe by the Herero community and the remaining liquid is the fermented buttermilk or Omashikwa, Consumers of Omashikwa have been complaining about it s sensory quality fluctuations. T he Department of Food Science and Technology of the University of Namibia took the initiative of finding out its problems by subjecting it to sensory evaluation in order to improve its quality. The sensory properties of two samples of fermented buttermilk ( Omashikwa ) ; the traditional and laboratory processed Omashikwa were investigated by descriptive and consumer preference analyses for improvement . Eight trained panelists using a 5- point hedonic scale were used to investigate the descriptive sensory characteristics of Omashikwa , while 45 consumers familiar with Omashikwa , determined the preference product of their choice . The results for traditional Omashikwa (TO) were compared to the laboratory made Omashikwa (LO ). The descriptive attributes scores on the levels of syneresis 3.4 (2.9) , filth 3.0 (1.8) , rancidity 3.4 (1.8) and bitterness 4.2 (2.5) , and were significantly higher for traditional omashikwa than LO. Aroma 2.6 (4.2), viscosity 2.5 (3.8) and texture 2.7 (4.2) were lower in traditional Omashikwa and this may explain the 80% consumer preference compared to the laboratory made Omashikwa . The application of good manufacturing practices (GMPs) on unit operations , particularly filtration and heat treatment of milk prior to fermentation and Hazard Analysis Critical Control Point (HACCP ) contributed significantly to the improvement and perceived sensory characteristic differences that exist between the traditional and laboratory made Omashikwa.

The study explored the e-teaching and learning experiences of lecturers amidst the COVID-19 pandemic at one of the University of Namibia satellite campuses. The study sample was 76 selected using the purposive sampling method from the population of 98. The study used a convergent parallel research design within a mixed methods research approach. A survey questionnaire and telephone interview were used to collect data. Data collected from open-ended questions and telephone interviews were analysed and categorised into themes while quantitative data were tabulated and analysed mainly by descriptive statistics with the use of Microsoft Excel. The study revealed that participants found using Moodle and other e-learning tools efficient as they save time and reduce the chances of spreading the virus since no gatherings were required. The study further revealed that participants had an opportunity to learn new skills despite not having prior experience in online teaching and learning as well as online course design. However, regular power outages and server incapacity to accommodate multiple devices caused many lecturers and students to miss virtual lessons. The study provided crucial information on the progress of lecturers and students' within the e-teaching and learning mode framework and recommended the campus server upgrading and the formal training of both lecturers and students on online teaching and learning tools to optimise learning.
El archivo musical documental: subjetividades y aportaciones al sujeto cultural

Published: January 2022

Este artículo surge de una investigación interesada en la recuperación del material documental —partituras musicales— usado por la Orquesta Sinfónica de Vientos de Boyacá, cuyo origen se remonta a finales del siglo XIX. La agrupación tuvo varias transiciones en cuanto a su función y a su pertenencia organizacional. En 2004 hubo una reestructuración interna que provocó el inicio de su decadencia. El estudio fue cualitativo-descriptivo, con un enfoque histórico-hermenéutico. Estuvo dividido en las siguientes fases: (1) diagnóstico, (2) clasificación, caracterización y valoración, (3) organización de la colección documental y (4) catalogación. Como resultado, se consolidó un catálogo de 328 compositores y 757 obras, organizado según criterios archivísticos y dispuesto para ser trasladado a un fondo documental encargado de preservar su contenido. Además, debido al vacío histórico y al limitado estado del arte para contextualizar el archivo documental, se hicieron diversas aproximaciones al ensamble y a su historia que permitieron iniciar cuatro estudios más. La importancia de este trabajo radica en el reconocimiento, en el trato y en la significación del valor cultural que supone un archivo musical y el sujeto cultural del cual parte: la banda sinfónica.
Renewable Energy Procurement in Ethiopia: Overcoming Obstacles in Procurement from Independent Power Producers
Authors: Ayele Seife , Shen Wei , Worako Tadesse Kuma , Baker Lucy H. , Hadush Samson
Published: January 2022

Developing countries are increasingly using auctions for the procurement of utility-scale renewable electricity, due to the potential for attracting private investment. However, auction design and implementation can face serious obstacles due to complex context-specific factors. In 2017, Ethiopia launched its Public–Private Partnership (PPP) policy and procurement framework to promote infrastructure development, including electricity generation. Since 2018, it has organised renewable energy auctions to procure new capacity from independent power producers (IPPs). However, the new framework faces numerous challenges. Using a literature review and primary data from more than 70 interviews and from stakeholder consultations, this study explores the political economy challenges and opportunities facing IPP project preparation, decision-making, coordination and implementation, and risks to investors. To date, Ethiopia has held two rounds of tenders to procure 1,000 megawatts (MW) of electricity from eight projects; the first tender for two solar photovoltaic (PV) projects led to the signing of Power Purchase Agreements (PPAs) and was hailed as one of the cheapest tariff rates in sub-Saharan Africa, at US$2.526 cents/kilowatt hour (kWh) over 25 years. However, none of the projects have yet become operational. This study also finds fault lines impeding the implementation of IPP projects, including the risk of foreign currency availability and convertibility of Ethiopian birr to expatriate profits. It proposes measures to overcome these obstacles and mitigate risks, to put Ethiopia on course to achieve universal access to electricity by 2030.
Measuring Carbon Emissions From Low carbon Cities in Rapidly Urbanising Countries – Nepal
Authors: Price Roz
Published: January 2022

Climate change and urbanisation are inextricably linked. With the acceleration of urbanisation in many developing countries, urban areas play a major role in energy consumption and carbon dioxide emissions. This is true of Nepal, which has experienced rapid urbanisation in recent decades. However, no studies were identified that evaluate the efforts of reducing greenhouse gas (GHG) emissions from low carbon cities in rapidly urbanising developing countries. Although, there is literature out there on this that focuses on developed countries and the Global North, this is outside the scope of this report. Given the rapid nature of this review and its limitations it was not possible to fully answer the question of whether investments in low-carbon cities reduce carbon emissions in rapidly urbanising contexts. The first section of this report looks at the theory of low carbon cities and touches on some of the methodologies for measuring carbon emissions from cities (and the complexities and difficulties with these). The second section looks at Nepal in more detail, highlighting previous literature which has attempted to quantify emissions from cities in Nepal (namely Kathmandu Valley) and the co-benefits of low carbon investment in Nepal. However, overall, literature was largely limited on these topics, and was often older being from 5 years or more ago. Of note is an emissions inventory for Nepal for 2016 by Sadavarte et al. (2019) – although other literature notes that data on emission characteristics are still limited (IMC Worldwide, 2020). ICLEI (2009) also produced city emissions profiles for 3 Nepalese cities, but these are quite outdated. There are several studies related to low carbon development pathways for major cities in developed countries or China, however such studies from the perspective of emerging cities from the developing world are limited. Research into other developing countries with similar characteristics to Nepal was briefly explored in this rapid review but there was not time to fully explore this literature base. Most of the literature explored is from academia, although some is from non-governmental organisations particularly those looking at engaging cities in climate action (such as C40). The literature explored does not look at gender issues or issues of people with disabilities.
Terrorism Eradication in ASEAN Countries: Human Rights Perspective
Authors: Satria Unggul Wicaksana Prakasa  , Al-Fatih Sholahuddin , Abdurrahman Raden Aji Haqqi
Published: January 2022

This research aims to discuss ASEAN counter-terrorism policy and its impact on human rights protection. The terrorism act of Abu Sayyaf in the Philippines, the spread of terrorism in Indonesia by JAT and JAD, and the rebellion movement in Pattani-Thailand are the most heard of terrorism cases in Southeast Asian countries. The research focused on the regulatory through comparative approaches. The result found that ASEAN has an agreement known as ASEAN Convention on Counter-Terrorism (ACCT) for combating terrorism. ACCT implementation in national legal regulations of ASEAN members in the midst of the spread of terrorism plays a crucial role in combating terrorism and its impact on human rights protection. However, the effort of eradicating terrorism in Southeast Asian countries is not in line with the principles of peace and regional integrity. The practice of authoritarianism and militarism has instead become most prominent as a result of perpetuating militarism-based legal regulations in resolving terrorism. Efforts for combating terrorism in Southeast Asia, therefore, leave a serious problem regarding the protection of human rights, the issue of impunity, attacks on civil society, and the involvement of the military which threatens territorial integrity. Those are at cross purposes with ACCT policies as well as national sovereignty, integrity, and security of ASEAN members. (Penelitian ini bertujuan membahas kebijakan anti-terorisme ASEAN dan dampaknya terhadap perlindungan hak asasi manusia. Aksi terorisme Abu Sayyaf di Filipina, penyebaran terorisme di Indonesia oleh JAT dan JAD, serta pemberontakan di Pattani-Thailand adalah kasus-kasus terorisme terpopuler yang terjadi di Asia Tenggara. Penelitian ini fokus pada peraturan perundang-undangan dengan pendekatan komparatif. Hasilnya menunjukkan bahwa ASEAN memiliki kesepakatan yang disebut Konvensi ASEAN tentang Kontra-Terorisme (ACCT) untuk memerangi terorisme. Penerapan ACCT dalam peraturan hukum nasional negara anggota ASEAN di tengah maraknya aksi terorisme sangat penting dalam upaya pemberantasan terorisme dan dampaknya terhadap perlindungan hak asasi manusia di ASEAN. Akan tetapi dalam praktiknya, pemberantasan terorisme di ASEAN masih belum sejalan dengan prinsip perdamaian dan keutuhan kawasan. Praktik otoritarianisme dan militerisme justru menjadi praktik paling menonjol yang dilakukan oleh negara-negara di ASEAN seiring dengan langgengnya regulasi hukum berbasis praktik militerisme dalam menyelesaikan kejahatan terorisme. Pemberantasan terorisme di Asia Tenggara menyisakan masalah serius terkait perlindungan hak asasi manusia, isu impunitas, serangan terhadap masyarakat sipil, dan keterlibatan militer yang mengancam integritas teritorial. Isu-isu tersebut bertentangan dengan Kebijakan ACCT serta kedaulatan, integritas nasional, dan keamanan anggota ASEAN.)

Study on Evolution of Cybercrime
Authors: VOICULESCU Robert-Cristian
Published: January 2022

In the following article we will see how cybercrime has evolved over the years, how it began from simple attacks which had no purpose other than inconveniencing those who were attacked, and led to the major crimes we see today, such as identity theft, frauds, child pornography and even terrorist attacks, that cause numerous problems for individuals, institutions and even countries. Furthemore, we will attempt to analyze the main ways in which cybercrime is realized, who are the people who engage in such activities, the means that they use in their efforts and how the authorities struggle to limit this phenomenon and put a stop to these attacks by bringing those who commit them to justice. Last but not least, we will try and comprehend how big is the threat of cybercrime at the moment and how it will threaten us in the years to come, how will the rapid advance in technology influence this relatively new type of crime and what even greater risks we will be exposed to in the future.

Igualdad y protección social: claves para un desarrollo inclusivo y sostenible
Authors: Arenas de Mesa Alberto , Cecchini Simone
Published: January 2022

Desde 2010 la Comisión Económica para América Latina y el Caribe (CEPAL) ha puesto el tema de la igualdad en el centro del debate regional y ha promovido el papel de la protección social como política pública clave para el desarrollo inclusivo y sostenible en la región. Este artículo aborda el marco conceptual de la matriz de desigualdad social y analiza las tendencias regionales de las múltiples dimensiones de la desigualdad, así como las propuestas en materia de protección y política social elaboradas por la cepal en el periodo reciente. Si bien los países de la región han tenido algunos avances en cuanto a reducción de la desigualdad del ingreso, ésta sigue siendo una de las más altas del mundo y es acompañada por desigualdades en otras dimensiones, como las de género, edad, territorio, raza y etnia, estatus migratorio, condición de discapacidad, entre otras. Para enfrentar tales desigualdades y superar la pobreza desde un enfoque de derechos, la CEPAL propone establecer sistemas universales, integrales y sostenibles de protección social. La protección social universal es necesaria para lograr los Objetivos de Desarrollo Sostenible “sin dejar a nadie atrás”, y representa una respuesta clave a la pandemia de Covid-19, la cual es necesaria para reconstruir con igualdad y sostenibilidad.

En la última década, en un proceso de producción de conocimiento que ha sido definido como continuidad con cambios, la Comisión Económica para América Latina y el Caribe (CEPAL) ha insistido en la centralidad de la igualdad y la sostenibilidad como fundamentos de un nuevo estilo de desarrollo. En este contexto se han formulado conceptos, ideas y propuestas como el cambio estructural progresivo; el gran impulso por la sostenibilidad; la macroeconomía para el desarrollo; la protección social universal y sensible a las diferencias; la autonomía física, política y económica de las mujeres; la garantía de ingresos básicos; la centralidad de la revolución tecnológica y de las políticas industriales; la desmercantilización del bienestar; la fiscalidad verde y progresiva; la sociedad del cuidado y el sistema de cuidados como pilar adicional del Estado de bienestar; el desmontaje de la cultura del privilegio en todas sus manifestaciones; la renovación de la matriz energética; la gobernanza de los recursos naturales; la economía circular; las soluciones basadas en la naturaleza; el impulso a la integración regional, y el fortalecimiento del multilaterialismo. Con base en sus propias características, prioridades y necesidades, México puede encontrar utilidad en ellas para construir y enriquecer el debate público en función de construir un nuevo estilo de desarrollo que disminuya las desigualdades, erradique la pobreza, garantice la sostenibilidad y eleve el bienestar de toda la población.
Un modelo de tres brechas
Authors: Gramkow Camila , Porcile Gabriel
Published: January 2022

Este artículo busca integrar en un marco analítico único las tres dimensiones del desarrollo sostenible, a saber, la económica, la social y la ambiental. Para ello se construye un modelo de tres brechas en la tradición estructuralista, donde se definen y contrastan tres tasas de crecimiento: la tasa máxima compatible con el equilibrio externo, la tasa máxima compatible con los compromisos ambientales asumidos por la región, y la tasa mínima necesaria para lograr niveles crecientes de igualdad. Se simulan escenarios de políticas mediante el modelo E3ME de Cambridge Econometrics, un modelo macroeconométrico de los sistemas socioeconómico, energético y ambiental. Los ejercicios de simulación confirman la importancia clave de combinar las políticas industrial y tecnológica con las de protección social a fin de promover el crecimiento y el empleo formal, junto con el desacoplamiento de las emisiones y la caída de la desigualdad. Una gobernanza internacional que favorezca la reducción de asimetrías tecnológicas y amplíe los espacios de política en la periferia es necesaria para avanzar hacia un nuevo estilo de desarrollo.

A simple model of a capsule robot is studied. The device moves upon a rough horizontal plane and consists of a capsule with an embedded motor and an internal moving mass. The motor generates a harmonic force acting on the bodies. Capsule propulsion is achieved by collisions of the inner body with the right wall of the shell. There is Coulomb friction between the capsule and the support, it prevents a possibility of reversal motion. A periodic motion is constructed such that the robot gains the maximal average velocity.
Qualitative Analysis of the Dynamics of a Trailed Wheeled Vehicle with Periodic Excitation

This article examines the dynamics of the movement of a wheeled vehicle consisting of two links (trolleys). The trolleys are articulated by a frame. One wheel pair is fixed on each link. Periodic excitation is created in the system due to the movement of a pair of masses along the axis of the first trolley. The center of mass of the second link coincides with the geometric center of the wheelset. The center of mass of the first link can be shifted along the axis relative to the geometric center of the wheelset. The movement of point masses does not change the center of mass of the trolley itself. Based on the joint solution of the Lagrange equations of motion with undetermined multipliers and time derivatives of nonholonomic coupling equations, a reduced system of differential equations is obtained, which is generally nonautonomous. A qualitative analysis of the dynamics of the system is carried out in the absence of periodic excitation and in the presence of periodic excitation. The article proves the boundedness of the solutions of the system under study, which gives the boundedness of the linear and angular velocities of the driving link of the articulated wheeled vehicle. Based on the numerical solution of the equations of motion, graphs of the desired mechanical parameters and the trajectory of motion are constructed. In the case of an unbiased center of mass, the solutions of the system can be periodic, quasi-periodic and asymptotic. In the case of a displaced center of mass, the system has asymptotic dynamics and the mobile transport system goes into rectilinear uniform motion.

Any obstacle-free path planning algorithm, in general, gives a sequence of waypoints that connect start and goal positions by a sequence of straight lines, which does not ensure the smoothness and the dynamic feasibility to maneuver the MAV. Kinodynamic-based motion planning is one of the ways to impose dynamic feasibility in planning. However, kinodynamic motion planning is not an optimal solution due to high computational demands for real-time applications. Thus, we explore path planning followed by kinodynamic smoothing while ensuring the dynamic feasibility of MAV. The main difference in the proposed technique is not to use kinodynamic planning when finding a feasible path, but rather to apply kinodynamic smoothing along the obtained feasible path. We have chosen a geometric-based path planning algorithm “RRT*” as the path finding algorithm. In the proposed technique, we modified the original RRT* introducing an adaptive search space and a steering function that helps to increase the consistency of the planner. Moreover, we propose a multiple RRT* that generates a set of desired paths. The optimal path from the generated paths is selected based on a cost function. Afterwards, we apply kinodynamic smoothing that will result in a dynamically feasible as well as obstacle-free path. Thereafter, a b-spline-based trajectory is generated to maneuver the vehicle autonomously in unknown environments. Finally, we have tested the proposed technique in various simulated environments. According to the experiment results, we were able to speed up the path planning task by 1.3 times when using the proposed multiple RRT* over the original RRT*.

Triglycerides of waste cooking oil reacted with methanol in refluxing toluene to yield mixtures of diglycerides, monoglycerides and fatty acid methyl esters (FAMEs) in the presence of 20% (w/w) catalyst/oil using the hydrophilic sulfonated silica (SiO2-SO3H) catalyst alone or with the addition of 10% (w/w) co-catalyst/oil [(Bun4N)](BF4) or Aliquat 336]. The addition of the ammonium salts to the catalyst lead to a decrease in the amounts of diglycerides in the products, but the concentrations of monoglycerides increased. Mixtures of [(Bun4N)](BF4)/catalyst were superior to catalyst alone or Aliquat 336/catalyst for promoting the production of mixtures with high concentrations of FAMEs. The same experiments were repeated using DMSO as the solvent. The use of the more polar solvent resulted in excellent conversion of the triglycerides to FAME esters with all three-catalyst media. A simplified mechanism is presented to account for the experimental results.

The recent glaciation of the southern part of the Altai is estimated (1256 glaciers with the total area of 559.15±31.13 km2), the area of the glaciers of the whole Altai mountains is evaluated by 1096.55 km2. In the southern part of Altai 2276 glaciers with the total area of 1348.43±56.16 km2 were reconstructed, the first estimate of the LIA glacial area for the whole Altai mountain system is given (2288.04 km2). Since the LIA the glaciers decrease by 59% in the southern part of Altai and by 47.9% for the whole Altai. The ELA in the southern part of Altai increased averagely by 106 m. The higher changes of ELA in relatively humid areas is probably caused by decrease of precipitation. Glaciers of Tavan Bogd glacial center degraded with higher rates after 1968 relative to the interval between 1850-1968. One of the intervals of the fastest shrinkage of the glaciers in 2000-2010 was caused by unfavorable for the glaciers dry and warm interval 1989-2004. However, the fast decrease of the glaciers in 2000-2010 was mainly caused by the shrinkage or disappearance of the smaller glaciers, large valley glaciers started fast retreat after 2010.

Published: January 2022

TP53 is a tumor suppressor gene that encodes a sequence-specific DNA-binding transcription factor activated by stressful stimuli and upregulates target genes involved in growth suppression, cell death, DNA repair, metabolism, among others. P53 is the most frequently mutated gene in tumors with mutations not only leading to loss-of-function (LOF), but also gain-of-function (GOF) which promotes tumor progression, and metastasis. The tumor-specific status of mutant p53 protein has suggested it is a promising target for cancer therapy. We summarize the current progress of targeting wild-type and mutant p53 for cancer therapy through biotherapeutic and biopharmaceutical methods for 1) boosting p53 activity in cancer, 2) p53-dependent and p53-independent strategies for targeting p53 pathway functional restoration in p53-mutated cancer, 3) targeting p53 in immunotherapy, and 4) combination therapies targeting p53, p53 checkpoints, or mutant p53 for cancer therapy.
