Integrated studies to investigate paleochannel aquifer in Dan Chang District, Suphan Buri Province, Western Thailand

Climate change is currently causing droughts in many parts of Thailand, especially in Dan Chang District, Suphan Buri Province where many areas are outside irrigation coverage and deep groundwater explorations are less successful due to groundwater shortages. Therefore, there is a need to explore other shallow groundwater (i.e. less than 15 m deep) resources to relieve the drought problems in the communities. This work uses integrated studies of remote sensing, geology and geophysics to identify the location of a paleochannel that contains shallow groundwater resources in the Nong Makha Mong Subdistrict, Dan Chang District, Suphan Buri Province. Potential sites were selected using preliminary remote sensing analysis along with field surveys. A high-resolution topography map from aerial photos was generated and 2D resistivity imaging surveys were conducted at the selected sites to delineate the location of the paleochannel. The drilled wells prove the success of the integrated study to identify the shallow groundwater in the paleochannel at a depth of 3 to 15 m with a groundwater yield of 4 m3/h. The sediments from the borehole suggest that a combination of alluvial deposits and fluvial sediments. Due to the relative lower cost of drilling shallow wells, this work could be used as a pilot project for local communities to explore shallow groundwater aquifers in paleochannels in areas that face a severe drought crisis and have very little deep groundwater potential.

ANÁLISE DA MULTIDIMENSIONALIDADE DOS CONCEITOS DE BACIA HIDROGRÁFICA

Resumo: A bacia hidrográfica (BH) é um objeto de estudo utilizado pela Geografia e pelas Ciências Ambientais, por isso novas definições foram criadas, compatibilizando essa célula de análise espacial e de planejamento com os estudos integrados. Assim, é importante averiguar se os conceitos criados sofreram adaptações e delimitações apropriadas para descreverem o objeto que definem e serem aplicados aos estudos tecnocientíficos. Nessa perspectiva, parte-se da hipótese de que os conceitos de BH, sub-bacia e microbacia hidrográficas foram adaptados, mas apresentam imprecisões nas suas delimitações conceituais. Portanto, objetivou-se identificar e analisar os conceitos mais citados na literatura, almejando aperfeiçoá-los. Para tanto, executou-se uma pesquisa bibliográfica na qual foram identificados e examinados os principais conceitos de BH, sub-bacia e microbacia hidrográfica utilizados atualmente. Posteriormente, buscaram-se características particulares de cada categoria de uma BH para distinguir as definições estudadas, bem como propor requalificações. Logo, verificou-se que os conceitos disponíveis na literatura sofreram adaptações, porém frequentemente reduzem uma BH e suas categorias hierárquicas aos seus aspectos hidrológicos ou espaciais. O sistema de hierarquização de BH e as definições analisadas apresentam falhas no ordenamento e nas delimitações conceituais de seus objetos, assim foi possível propor aprimoramentos nas definições estudadas.

ANALYSIS OF MULTIDIMENSIONALITY OF HYDROGRAPHIC BASIN CONCEPTS Abstract: The hydrographic basin (HB) is a study object used for Geography and Environmental Sciences, therefore new definitions have been created, making this cell of spatial analysis and planning compatible with integrated studies. Thus, it is important to ascertain whether the concepts created have undergone appropriate adaptations and delimitations to describe the object that they define and apply to techno-scientific studies. In this perspective, it is based on the hypothesis that the concepts of HB, hydrographic sub-basin and microbasin have been adapted, but they present naccuracies in their conceptual delimitations. Therefore, the objective was to identify and analyze the most cited concepts in literature, aiming to improve them. For this, bibliographical research was carried out in which the main concepts of HB, sub-basin and microbasin used today were identified and examined. Subsequently, particular characteristics of each category of a HB were sought to distinguish the definitions studied, as well as to propose requalifications. Therefore, it was verified that the concepts available in literature have undergone adaptations, but often reduce a HB and its hierarchical categories to its hydrological or spatial aspects. The hierarchical system of HB and the analyzed definitions present faults in the ordering and conceptual delimitations of its objects, so it was possible to propose improvements in the definitions studied.

The synergistic coordination of DNA 5-hydroxylmethylcytosine and RNA 5-methycytosine regulates human foetal development

After implantation, complex and highly specialized molecular events render functionally distinct organ formation, whereas how the epigenome shapes organ-specific development remains to be fully elucidated. Here, Nano-hmC-Seal and RNA bisulfite sequencing (RNA-BisSeq) were performed and the first multilayer landscapes of both DNA 5hmC and RNA m5C epigenome, as well as the accompanying transcriptome were obtained, in the heart, kidney, liver and lung of the human foetuses at 13 − 28 weeks with 123 samples in total. DNA 5hmC plays a consistently leading role, while RNA m5C acts as a dynamic downstream regulatory valve in regulating gene expression with a turning point of 18–19 weeks. Although, these modifications appear to coordinate in general, they also play different roles with regard to specific functions. Our integrated studies illustrate the epigenetic maps during different stages of human foetal organogenesis, which provide a foundation for understanding the in-depth epigenetic mechanisms for early development and birth defects.

Integrated studies of the physical and mechanical properties of cotton fabric

The nature of the adhesive forces of the K-4 preparation is manifested in the occurrence of hydrogen bonds between molecules, as a substance with a sufficiently developed ability to form hydrogen bonds with cellulose. By the method of a one-factor experiment, the regularities of the influence of the concentration of the preparation alkaline-hydrolyzed PAN product on shrinkage, the total opening angle and weight gain of the fabric were revealed. It was found that the concentration of the preparation, equal to 75 g/l, provides the minimum shrinkage and rinsability of the sizing, as well as at the same time the largest value of TOA.

The importance of multidisciplinary cooperation and transdisciplinary research for overcoming the crisis of social humanities

We live in an age of the rise of scientific positivism, methodological particularism, and disciplinary chaos. We are witnessing the process of fragmentation of the scientific system, partialization, dehumanization and marginalization of the social sciences. The paper discusses the importance of multidisciplinary and transdisciplinary research for overcoming the crisis of social sciences and humanities. In this context, special emphasis is placed on the importance of improving the practice of integrated studies in the education system at universities; and especially the importance of cooperation between natural / biomedical research and humanities (genetics, ecology, anthropology, demography, philosophy, ethics, history, psychology and sociology).
