Pengkayaan Unsur Tanah Jarang Sc- Y Pada Endapan Laterit Pulau Sebuku Provinsi Kalimantan Selatan

Sebuku Island is located at the Maratus high physiography which has an ultramafic rock composition. Ultramafic rocks exposed on the surface will usually experience weathering caused by the influence of climate and rainfall such as on Sebuku Island. One of the products produced from the weathering of these ultramafic rocks is laterite deposits. Laterite contains ore minerals that have economic value including rare earth elements, especially Scandium (Sc) and Yttrium (Y). This study aims to determine the geological conditions, laterite characteristics, and the content of rare earth elements Scandium and Yttrium. The method used is a field survey using petrographic analysis, XRF (X-Ray Fluorescence), and ICP-MS (Inductively Coupled Plasma Mass Spectrometry). Based on the geomorphological analysis of the research area, there are two original forms, namely denudational origin, and fluvial origin, then this original form is divided into four landforms, namely weak undulating plains (D5), weakly wavy denudation (D6), lakes (F3). and Swamp (F4). The flow pattern that developed in the research area is Rectangular (R). The geological structure that develops in the study area is a fault with a general direction of Northwest-Southeast such as a left horizontal fault. Characteristics of laterite which has a thickness of 8-12 meters. Scandium (Sc) and Yttrium (Y) levels in the drill hole from the topmost layer from laterite (Limonite) to the bottom (Badrock), scandium are at 48-5.9 ppm and Yttrium levels are at 23-0.12 ppm and are richest in the lomonite zone.

Fertility trends in Serbia during the 1990s

The 1990s represent an exceptionally complex period for the population of Serbia. In addition to the impact of long-term factors, various tumultuous events affected its demographic development, such as breaking apart of former Yugoslavia, armed conflicts in the neighboring countries, sanctions imposed by the international community, social changes (transition transformation or regression), deep economic crisis, collapse of social stratification political problems, institutional crisis, and NATO military intervention. Maladjustment to the changed system of values and norms, lower level of personal attainment, feeling of insecurity, and living under permanent stress are the main features of life at an individual psychological level. Deprivation or living at the subsistence level are the main elements of the economic cost sustained by the majority of the population. How have these changes affected an individual's decision to have children? The analysis of futility indicators points to an obvious decline in the number of births across low fertility regions of Serbia. Also, the analysis has raised the question why the decline in population fertility in the low fertility regions was not even higher, bearing in mind the experiences undergone by the countries with economy in transition as well as the depth of the crisis in society. In that sense several factors come to mind. The most important are the universality of marriage socio-psychological investigations confirmed domination of the traditional character or mentality in Serbia during the 1990s, and the government’s approach to the issue of fertility improved during this time. Besides demographic needs were carefully taken into account in all amendments to the old and formulation of the new measures in the area of social policy. Mention should be made of measures ensuring employment rights of women and their entitlement to maternity leave, maternity pay, and provision of institutionalized care for the children. On the other hand under-reporting of live births, lack of knowledge on the size and characteristics of emigration flows limited the analysis of population fertility in Kosovo and Metohia. But, registered data as well as survey results show to the perseverance of the fertility model of transitional type displaying obvious traditional elements

A qualitative study on the educational needs of young people with chronic conditions transitioning from pediatric to adult care

The specific skills needed for the transition to help in facilitating the life plans and health of young people are still poorly understood. This study explored the educational needs of young people with diverse chronic conditions during their transition from pediatric to adult care. Methods: Qualitative semi-structured interviews were conducted with 17 young people with chronic conditions. A thematic analysis was conducted to examine the data. Results: Five themes emerged from the data, identified through the following core topics: learning how to have a new role, learning how to adopt a new lifestyle, learning how to use a new health care service, maintaining a dual relationship with pediatric and adult care, and having experience sharing with peers. Conclusion: A shift in perspective takes place when the transition is examined through the words of young people themselves. To them, moving from pediatric to adult care is not viewed as the heart of the process. It is instead a change among other changes. In order to encourage a transition in which the needs of young people are met, educational measures could focus on the acquisition of broad skills, while also being person-centered.

Analysis of Low-Density Effects in Suborbital Flight of FAST20XX

The paper studies the high altitude effects to the future hypersonic/suborbital re-entry vehicle SpaceLiner developed in the framework of EC-funded FAST20XX project. Bridging functions have been developed and validated by means of DSMC calculations. The effects of rarefaction on global longitudinal aerodynamics of SpaceLiner in the range of altitude 65÷85 km have been pointed out by comparing to the aerodatabase in continuum regime conditions. DSMC computation has been done in the higher SpaceLiner altitude point confirming the bridging function results and providing heat transfer estimations

Nitric oxide- and hydrogen peroxide-responsive gene regulation during cell death induction in tobacco

Nitric oxide (NO) and hydrogen peroxide (H2O2) are regulatory molecules in various developmental processes and stress responses. Tobacco (Nicotiana tabacum) leaves exposed to moderate high light dramatically potentiated NO-mediated cell death in catalase-deficient (CAT1AS) but not in wild-type plants, providing genetic evidence for a partnership between NO and H2O2 during the induction of programmed cell death. With this experimental model system, the specific impact on gene expression was characterized by either NO or H2O2 alone or both molecules combined. By means of genome-wide cDNA-amplified fragment length polymorphism analysis, transcriptional changes were compared in high light-treated CAT1AS and wild-type leaves treated with or without the NO donor sodium nitroprusside. Differential gene expression was detected for 214 of the approximately 8,000 transcript fragments examined. For 108 fragments, sequence analysis revealed homology to genes with a role in signal transduction, defense response, hormone interplay, proteolysis, transport, and metabolism. Surprisingly, only 16 genes were specifically induced by the combined action of NO and H2O2, whereas the majority were regulated by either of them alone. At least seven transcription factors were mutually up-regulated, indicating significant overlap between NO and H2O2 signaling pathways. These results consolidate significant cross-talk between NO and H2O2, provide new insight into the early transcriptional response of plants to increased NO and H2O2 levels, and identify target genes of the combined action of NO and H2O2 during the induction of plant cell death
