The Relationship

Research about Oligo-Miocene limestones in Java has always been interesting to study in order to understand the relationship between tectonic-volcanic, sedimentation, and petroleum potential. The Lengkong limestone formation is interesting to study especially its sedimentology aspects. There is no Scientific Publication about the Lengkong Formation which discusses detailed sedimentology aspects. Those aspects are important to modify the geological map, scale of 1: 50000 which was published by the ministry of energy and mineral resources. This research was conducted to determine the sedimentology process and development of a depositional environment of the Lengkong formation in the Cimapag River. The research area is located in Neglasari, Lengkong District, Sukabumi. The method used includes field surveys and laboratory analysis. A field survey embodies sedimentology data collection and rock sampling, which was then made into a detailed stratigraphic column. Rock samples were analyzed petrographically for 12 samples to determine microfacies. The results cover three limestone facies, namely wackestone, wackestone-packstone, and packstone facies. The sedimentation of the Lengkong Formation indicates a sea-level decrease of the Interbuild Basin Floor to Deep Marine Off reef

Two level zone index system of the provincial highway geotechnical zone was established on the basis of analysis of the relationship between geotechnical elements and highway engineering. The highway rock-soil type conversion rules and the zone standard of two level zone indexes were set through comparative analysis of the characteristics of rock-soil on the engineering geological map. According to the general principles and methods of zone study, the research framework of provincial highway geotechnical zone was constructed. Under the guidance of this framework, Shandong province highway geotechnical zone was completed and the whole research area was divided into 2 grade I and 5 grade II. The results indicate that the new highway geotechnical zone can better reflect the variation of rock-soil engineering properties in Shandong province. The result verifies the scientificalness and effectiveness of the research framework of provincial highway geotechnical zone and provides basic data for research on highway geotechnical zone of nationwide.

The study area represents a small part of the Lesser Himalaya in western Nepal and lies about 346 km west from Kathmandu. It covers 250 km area representing some parts of Gulmi and Baglung districts. The area was selected for the present study on the impression from the previous geological map that has showed some metallic mineral resources like iron, copper and lead in the region. Similarly, studies reveal that there is very complicated geological structure which raised the interest for the study. Main objective of the study was to prepare a geological map of the area in a scale of 1:25,000 and study the possible mineral deposits. An extensive geological mapping was carried out in the field covering at one data within one centimetre of the map scale and large number of samples was collected for the petrographic as well as ore genesis studies. The rocks of the region were mapped under two geological units as the Nourpul Formation (older) and the Dhading Dolomite (younger).  There are a series of folds in the area. From regional to micro-scale all folds are trending towards east-west. The Badi Gad Fault and the Harewa Khola Thrust are the regional scale thrust mapped in the area. The Badi Gad is considered as a strike-slip in nature. The Harewa Khola Thrust is probably an imbricate fault. It has propagated to the north which is out of sequence in nature. Some metallic minerals like copper and iron along with old working mines were observed during the study. Occurrences of copper and iron mineralization has been mapped and described. Present study revealed that copper mineralization is limited within the veins and boudinage forms as hydrothermal deposit while the iron is tabular and syngenetic in nature.

In 1994, an article appeared in the Italian journal Archeologia Medievale, written by Chris Wickham and Riccardo Francovich, entitled ‘Uno scavo archeologico ed il problema dello sviluppo della signoria territoriale: Rocca San Silvestro e i rapporti di produzione minerari’. It marked a breakthrough in the study of the exploitation of mineral resources (especially silver) in relation to forms of power, and the associated economic structure, and control of production between the twelfth and thirteenth centuries. On the basis of the data available to archeological research at the time, the article ended with a series of open questions, especially relating to the early medieval period. The new campaign of field research, focused on the mining landscape of the Colline Metallifere in southern Tuscany, has made it possible to gather more information. While the data that has now been gathered are not yet sufficient to give definite and complete answers to those questions, they nevertheless allow us to now formulate some hypotheses which may serve as the foundations for broader considerations as regards the relationship between the exploitation of a fundamental resource for the economy of the time, and the main players and agents in that system of exploitation, within a landscape that was undergoing transformation in the period between the early medieval period and the middle centuries of the Middle Ages.

Post Disaster

After an earthquake occurs, field surveys are conducted by relevant authorities to assess the damage suffered by buildings. The field survey is essential as it ensures the safety of residents and provides the necessary information to local authorities for post-disaster recovery. In Japan, a primary (mandatory) exterior survey is conducted first, and a secondary (voluntary) interior survey is performed subsequently if the residents request a reinvestigation. However, a major challenge associated with field surveys is the substantial time cost of determining the damage grades. Moreover, an interior survey is performed only after receiving the reinvestigation request from occupants, which further delays the decision-making process. In addition, the risk of incorrect damage estimation during the exterior survey must be considered because underestimating the damage can endanger the residents. Therefore, in this study, a three-part analysis (Parts I–III), where each part corresponds to a distinct stage of the standard damage assessment procedure, was performed to characterize the relationship between the building parameters and damage grades at different stages. To further explore the possibility of accelerating decision-making, predictive modeling was performed in each part. The Part I results indicate that estimating the final damage grade for all buildings immediately after the exterior survey is similar to treating the exterior survey results as the final ones. The Part II results show that buildings that potentially require an interior survey can be predicted with reasonable accuracy after the exterior survey. In buildings for which reinvestigations have been requested, Part III demonstrates that the risk of underestimation in the exterior survey can be predicted reliably.

Cell death is a critical biological process, serving many important functions within multicellular organisms. Aberrations in cell death can contribute to the pathology of human diseases. Significant progress made in the research area enormously speeds up our understanding of the biochemical and molecular mechanisms of cell death. According to the distinct morphological and biochemical characteristics, cell death can be triggered by extrinsic or intrinsic apoptosis, regulated necrosis, autophagic cell death, and mitotic catastrophe. Nevertheless, the realization that all of these efforts seek to pursue an effective treatment and cure for the disease has spurred a significant interest in the development of promising biomarkers of cell death to early diagnose disease and accurately predict disease progression and outcome. In this review, we summarize recent knowledge about cell death, survey current and emerging biomarkers of cell death, and discuss the relationship with human diseases.

A detailed geological investigation was carried out to assess the distribution of minerals and their geological control in Bandipur-Gondrang area of Tanahu district, a part of Lesser Himalaya in central Nepal. The area is found rich in both metallic and non-metallic mineral deposits. The main metallic minerals found are iron in Phalamdada and Labdi Khola, copper in Bhut Khola and poly-metallic deposits including suspected gold in Bhangeri Khola and Jaubari Khola-Bar Khola sections. A large deposit of inorganic carbon is found around the Gondrang-Watak area. Similarly, a good quality of green marble (metabasite) is found as decorative stone in Bagar Khola area and good quality of roofing stone in Bandipur area. In addition to these economic deposits other several sub economic to non-economic mineral are also located in the geological map of the area. Categorization of these mineral deposits is based on the probable reserve and laboratory analysis of related samples. Geological control of mineral deposits is considered to be the stratigraphic, structural, metamorphic and hydrothermal. Iron mineralization of the area is found stratigraphical control, copper deposits by magmatism of basic rocks (amphibolites), and poly-metallic deposits are related to the hydrothermal processes.
