The Quimiag parish in Riobamba canton is purely agricultural. For this reason, this study aimed to develop sustainability strategies to strengthen its agricultural systems. 24 communities were involved in the research and 312 Agricultural Productive Units (UPAs) were surveyed. Basic information was collected and then a proposal was developed using the logical framework matrix methodology and focusing on 3 sustainability components: social, productive and economical. In terms of the social component, it was observed that producers were on average 46 years old and 65% of producers had a primary education. In terms of the production component, we found that maize, beans and potato are the main agricultural products, while dairy cattle, cuyes and pigs are the main livestock in the area. Capacity building, production technology, production credit management and the generation of partnerships with state institutions and private companies are the main sustainability strategies proposed for the Quimiag parish, and adopting these would lead to improvements in profitability rates.

El espíritu juvenil de los estudiantes de convertirse en emprendedores es notorio a simple vista. Sin embargo, el objetivo general de esta investigación fue analizar la actitud emprendedora de los estudiantes varones del Tecnológico Nacional de México campus Tepeaca. Se encuestó a ciento setenta y dos estudiantes varones. El cuestionario fue diseñado y validado por expertos en el área. La validación se llevó a cabo por un método nuevo; éste consiste en aplicar un análisis factorial de Pearson para las correlaciones lineales y chi cuadrado para las asociaciones no lineales. Se le aplican cinco postulados para depurar y validar cada ítem. Los ítems se toman como factores o variables independientes para contrastar las hipótesis de trabajo. El muestreo fue aleatorio. La matriz de resultados obtenida después de aplicar la correlación de Pearson arrojó tres correlaciones por encima de 0.7. Con estas correlaciones se validaron seis hipótesis lineales. Solo se seleccionaron ocho hipótesis no lineales validadas por chi cuadrado debido al espacio limitado de un artículo científico. En general, se diseñaron 400 hipótesis de trabajo en el orden de 20 ítems tomados en orden de dos a dos. Se concluye que los estudiantes encuestados poseen amplio conocimiento del emprendimiento. Éstos están preparados para la innovación, creación y éxito en las empresas tanto de su propiedad como las empresas donde presten sus servicios.
The youthful spirit of students to become entrepreneurs is apparent to the naked eye. However, the general objective of this research was to analyze the entrepreneurial attitude of male students from the Tecnológico Nacional de México campus, Tepeaca.

Highlight ResearchThe F2 of GH-transgenic B. imbellis was successfully producedThe transgene inheritance by the F2 fish was more than 90%The growth and body size of transgenic fish was significantly higher than controlF2 fish reached a larger body size in a shorter period compared to the F1 AbstractIn our previous research, we had successfully produced G0 and G1 Pangasianodon hypophthalmus growth hormone (PhGH) transgenic B. imbellis, native ornamental betta from Indonesia, which its giant-sized variant has valuable price for the breeders. The G0 and G1 transgenic (TG) fish showed higher growth rate and body size compared to the non-transgenic (NT) fish. The study was aimed to produce and evaluate the consistencies of transgene transmission and expression in G2 generation. The growth rate and body size between TG and NT fish was also compared. The G2 generation was produced using crosses between TG and NT G1 fish: ♂TG × ♀TG, ♂TG × ♀NT, ♂NT × ♀TG, and ♂NT ×♀ NT. Fish were reared for 12 weeks, and transgene detection was performed using the polymerase chain reaction method (PCR) on isolated DNA from the caudal fin clips. The endogenous and exogenous GH expression analysis was conducted using the quantitative real-time PCR (qPCR) method. The results showed that the inheritance of the GH transgene by the G2 fish was more than 90% in all transgenic crosses. Endogenous GH was expressed at the same levels in the brain of TG and NT fish, but the exogenous GH expression was highly detected only in the TG fish. The G2 transgenic fish had a higher specific growth rate, up to 31%, compared to the control. The body length of TG crosses were 23−35% higher and had 111−135% higher body weight compared to NT fish. These results showed a promising approached in mass-producing stable lines of giant-sized betta using the GH-transgenic technology.

Highlight ResearchThere has been a significant decrease in growth, condition factors, hepatosomatic index along viscerosomatic index with the length of time for feed restriction, although fasting for up to 28 days did not cause fish mortalityHematological parameters such as RBCs, WBCs, hematocrit, and hemoglobin decreased significantly, but after re-feeding increased significantly in consecutive timesThe blood glucose levels decreased during feed restriction and gradually increased after re-feedingFeed restriction ﬁsh gained weight continuously during re-feeding, but no displaying compensatory growthThe decrease in hematological parameters did not indicate stress levels in fish, but reflected a lack of nutrition condition AbstractThe management of red tilapia culture can be improved through restriction of feed. This study aimed to determine the impact of feed restriction time and re-feeding on the growth and hematological performance of juvenile red tilapia. This study used an experimental method with a completely randomized design consisting of five treatments with four replications, namely the fish were given food for 28 days (A), 7 days of feed restriction followed by 21 days of refeeding (B), 14 days of feed restriction followed by 14 days of refeeding (C), 21 days of feed restriction followed by 7 days of refeeding (D) and 28 days of feed restriction (E). The parameters observed were growth, biometry, and hematological values. The results showed that during the feed restriction period there was a significant decrease in growth, condition factors, hepatosomatic index along with viscerosomatic index with the length of time for feed restriction, although fasting for up to 28 days did not cause fish mortality. Hematological parameters such as RBCs, WBCs, hematocrit, and hemoglobin decreased significantly, but after re-feeding, they increased significantly in consecutive times. As for the blood glucose levels decreased during feed restriction and gradually increased after re-feeding. This study stated that feed restriction ﬁsh gained weight continuously during re-feeding, but no displaying compensatory growth. The results suggested that the decrease in hematological parameters did not indicate stress levels in fish, but reflected a lack of nutrition condition.

The quality of potato seeds is important to support increased production. The majority of farmers do not certify potato seeds, which can result in various risks for potato seed production activities. This research aims to identify the risks of potato seed production and formulate risk control strategies for potato seeds production. The research uses house of risk method. The results of this study show thirty-nine identified risk events. The most impactful risk event was rotten potato. Thirty-two identified risk agents with two priorities must be handled first. The most effective ways in handling strategy are training, the certification of potato seed breeder farmers, potato seed certification, as well as purchasing breeder seeds from vegetable crop research center and from other seed breeders. This research suggests the needs to produce quality potato seeds by certifying potato seed and to update the competency certification of potato seed breeders.

Published: September 2021

Rainfed lowland farming production is generally lower than irrigated lowland rice due to area differentiation regional features. Rainfed lowland rice farming can only produce rice during the rainy season because lowland rice cannot be planted in the dry season. The purposes of this study are (1) to analyze the risk of production and income of rice farming in rainfed lowland farming and (2) to investigate the factors influencing the risk of rice farming in rainfed lowland farming. Data were collected from 100 respondents of rice farmers in four sub-districts in Maros Regency using the multi-stage cluster random sampling technique. The analysis of production and income risks were performed using multiple linear regression with the heteroscedastic method. The results have shown that rice farming in rainfed lowland farming poses a risk to production and income. The variables that significantly influence the rainfed lowland rice farming are land area, the number of seeds, the amount of urea fertilizer and the amount of pesticide. Farmers are required to manage risk by prioritizing the effectiveness and efficiency production factors as needed. Similarly the government is expected to assist farmers in maintaining the level of rice selling prices.

Advanced Seismic Data Interpretation for Carbonate Targets Based on Optimized Processing Techniques
Authors: Fischer Klaus C. , Möller Ulrich , Marschall Roland 
Published: September 2021

ABSTRACT
Seismic data from the shelf area of the Cretaceous Shu’aiba Formation in Abu Dhabi is used to investigate stratigraphic and structural seismic anomalies. The data consists of a 2-D grid of seismic lines, acquired in the late 1980s and 1993. The data was reprocessed in several phases. The first phase consists of standard time domain processing upto final Dip Move Out stack and migration. In the second phase, a macro-velocity model for post-stack depth migration is generated and tested by the interpreters. The third phase is the interpretation of the pre-stack depth migration stack. Due to the structural irregularity of the Shu’aiba Formation, the pre-stack depth migrated data is considered the most reliable for Amplitude Versus Offset analysis. Further steps are L-1 deconvolution followed by Born Inversion. These last steps are required before the lithology can be modeled with high-resolution. The final lithological model is verified by applying forward modeling. The lithological model forms the basis for reservoir and geostatistical evaluations which account for heterogeneities.
Lipid Dyshomeostasis and Inherited Cerebellar Ataxia

Abstract
Cerebellar ataxia is a neurological disorder originating in the cerebellum and can be divided into different subtypes. The etiology of these disorders is complicated, especially in inherited disorders. Currently, nearly all disorders remain incurable. To precisely diagnose and treat these diseases, studies on their molecular mechanisms have been conducted extensively in the past. Accumulating evidence has demonstrated that some common pathogenic mechanisms exist within each subtype of inherited ataxia. However, no reports have indicated whether there is a common mechanism among the different subtypes of cerebellar ataxia. In this review, we summarize the available references and databases on neurological disorders characterized by cerebellar ataxia and show that a subset of genes involved in lipid homeostasis form a new group that may cause ataxic disorders through a common mechanism. This common signaling pathway can provide a valuable reference for future diagnosis and treatment of ataxic disorders.

Abstract
Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare yet serious adverse effect of adenoviral vector vaccines (AstraZeneca and Johnson & Johnson) against COVID-191. Anti-platelet factor 4 (PF4) antibodies are present in VITT patients2,3. Although the current view suggests that platelet activation by anti-PF4 antibodies is the cause of thrombosis there is as yet no direct evidence that the antibodies induce clot formation and thrombocytopenia (reduction in platelet counts) in VITT and the mechanisms involved remain unknown4. Here we show that VITT antibodies induce thrombosis and thrombocytopenia, and that thrombus formation is mediated by neutrophil extracellular traps (NETs). We found markers of NETosis, abundance of neutrophil/platelet aggregates and presence of neutrophils undergoing NETosis in patients with active VITT. VITT antibodies directly stimulate neutrophils to release NETs and induce thrombus formation containing abundant platelets, neutrophils, fibrin, extracellular DNA and citrullinated histone H3 using an in vitro blood flow microfluidic system. In transgenic mice expressing human PF4 and FcγRIIa, VITT antibodies lead to thrombosis, thrombocytopenia and formation of low density granulocytes. Pharmacological and genetic inhibition of NETosis prevents VITT-induced thrombosis in mice but not thrombocytopenia. In contrast, in vivo blockage of FcγRIIa abrogates both thrombosis and thrombocytopenia suggesting they are distinct processes. Our findings indicate that VITT antibodies activate cells via FcγRIIa and are responsible for thrombosis and thrombocytopenia. This study identifies NETosis as a pathogenic mechanism for thrombus formation in VITT. We anticipate our findings will motivate future development of NETosis and FcγRIIa inhibitors as potential specific therapies for VITT and consequently better patient outcomes.

Abstract
Background: Achalasia is a rare primary esophageal motility disorder disease. It is reported that the long-term effect of fully coated anti-reflux metal stent (FCARMS) implantation is satisfactory. Operated by a skilled and experienced endoscopist, the effect of POEM treatment is equivalent to that of surgical myotomy. So far, there is still few evidence to prove stent implantation or POEM which is better for achalasia. The choice of treatment for achalasia is still controversial. Therefore, the aim of this study is to find a more suitable therapy for achalasia by comparing the efficacy of FCARMS implantation and POEM.Methods: A propensity score (PS) matching (1:2) was used in this retrospective cohort study. Data collected from consecutive patients of Achalasia, receiving FCARMS implantation or POEM therapy at the department of gastroenterology, the Seventh Medical Center of the Chinese People’s Liberation Army General Hospital from May 2007 to May 2018. According to their previous treatment, they are divided into two groups, FCARMS group and POEM group. Clinical efficacy and complications were compared between the two groups.Results: A total of 166 cases were collected, including 113 cases of FCARMS and 53 cases of POEM. By PS matching, 150 patients were enrolled (100 cases of FCARMS and 50 cases of POEM). By comparison, the FCARMS group has shorter operation time, shorter fasting time and lower hospitalization costs than the POEM group (p<0.05). Common complications in the FCARMS group are nausea, vomiting, and stent shift. Repetitions of gastroscopy in the FCARMS group was more often, which were 3.8±2.4（vs 2.1±1.8 of POEM）(p=0.00<0.05) The 6-month remission rates of the FCARMS combination POEM group were 89% and 94%, respectively (p=0.39), and the 2-year remission rates were 61% and 90%, respectively (p=0.00).Conclusions: Stent placement is a cost-effective and safe treatment option for achalasia. The short-term effect (less than 6 mons) of FCARMS is similar to that of POEM, the long-term effect (more than 2 years)，POEM is better than FCARMS. HRMⅡis most suitable for POEM treatment. It indicate that Patients can choose treatment methods according to their own conditions.
Analyzing Post-Disaster Recovery Success Factors in Developing Countries Using Interpretive Structural Modeling Approach

Published: September 2021

Abstract
There remains a significant gap in emergency management efforts and governance during natural disasters in developing countries, leading to preventable losses of life and damages to properties. Recent efforts to improve disaster responses and achieve long-term post-disaster recovery are threatened by increasing frequency of natural disasters and consistent failures in managing and planning responses. This study aims to: (1) investigate current state of emergency management practices using two case studies i.e., hurricanes in South Florida, United States and earthquakes in Kathmandu, Nepal; and (2) investigate the critical success factors that foster faster post-disaster recovery in developing countries, rank them, and develop an Interpretive Structural Modeling (ISM) framework. To achieve these objectives, the study conducted a systematic literature review (SLR) and questionnaire surveys to stakeholders who reside in disaster-prone communities both in the United States and Nepal. The study results indicated that bolstering critical transportation systems is the most influential factor that impacts other success factors during post-disaster recovery in developing countries. Moreover, the study results also indicated that a significant gap exists in awareness and proactive decision-making skills among many Nepalese residents due to the lack of emergency management training, policies, and leadership in emergency situations. The findings of this study contribute to two bodies of knowledge: firstly, the construction management through embracing systematic ISM framework that bridges the gaps in post-disaster recovery efforts in developing countries; and secondly, disaster risk management by demonstrating the strengths and weaknesses of emergency management practices in disaster-prone communities of developed and developing countries.
