Perancangan Sistem Otomatis Update pada Aplikasi Desktop Abios

Unlike web applications easier to update the latest version, desktop applications more difficult and must involve the user in doing so. It is caused by a desktop application is an application that is installed in the computer user. The purpose of this research is to design an automatic system updates on a desktop application, an example case: Application Binus International Operational Support (ABIOS). This research used literature study and system design. In desktop applications, often there is update the latest applications that are not known to the user who sometimes fatal and disrupt business operations. Generally, developer will inform the changes version to user that they can update the application. In an update of applications, should be done by the system automatically, not manually by users. Once in a while, the user background is not from computer base. After doing the research, it can be concluded that the system automatically updates the application has benefits to users in obtaining information regarding the latest version, and can assist in automatically update the latest application is based on computerization. For further development of this system is expected to operate on multi platforms and or mobile applications

Photoelectrochemical cell for simultaneous electricity generation and heavy metals recovery from wastewater

The feasibility of simultaneous recovery of heavy metals from wastewater (e.g., acid mining and electroplating) and production of electricity is demonstrated in a novel photoelectrochemical cell (PEC). The photoanode of the cell bears a nanoparticulate titania (TiO2) film capped with the block copolymer [poly(ethylene glycol)-b-poly(propylene glycol)-b-poly(ethylene glycol)] hole scavenger, which consumed photogenerated holes, while the photogenerated electrons transferred to a copper cathode reducing dissolved metal ions and produced electricity. Dissolved silver Ag+, copper Cu2+, hexavalent chromium as dichromate Cr2O72− and lead Pb2+ ions in a mixture (0.2 mM each) were removed at different rates, according to their reduction potentials. Reduced Ag+, Cu2+ and Pb2+ ions produced metal deposits on the cathode electrode which were mechanically recovered, while Cr2O72− reduced to the less toxic Cr3+ in solution. The cell produced a current density Jsc of 0.23 mA/cm2, an open circuit voltage Voc of 0.63 V and a maximum power density of 0.084 mW/cm2. A satisfactory performance of this PEC for the treatment of lead-acid battery wastewater was observed. The cathodic reduction of heavy metals was limited by the rate of electron-hole generation at the photoanode. The PEC performance decreased by 30% after 9 consecutive runs, caused by the photoanode progressive degradation

Printed frequency selective surfaces on textiles

This letter introduces a novel technique for inkjet printing frequency selective surfaces (FSS) on textiles. The challenge of printing an inkjet layer of three micron thickness on polyester cotton with a surface roughness of the order of 150 microns is achieved with a screen printed interface layer. The conducting inkjet layer is then printed directly on top of the interface layer. A screen mask was used so that the interface layer was only printed directly below the conducting ink. A square FSS structure has been fabricated and the measured shielding has been compared to simulations

Mechanism and experimental study on the photocatalytic performance of Ag/AgCl @ chiral TiO2 nanofibers photocatalyst: the impact of wastewater components

© 2014 Elsevier B.V.The effect of the water matrix components of a secondary effluent of a urban wastewater treatment plant on the photocatalytic activity of Ag/AgCl @ chiral TiO2 nanofibers and the undergoing reaction mechanisms were investigated. These effects were evaluated through the water components-induced changes on the net rate of hydroxyl radical (•OH) generation and modeled using a relative rate technique. Dissolved organic matter DOM (k=-2.8×108M-1s-1) scavenged reactive oxygen species, Cl- (k=-5.3×108M-1s-1) accelerated the transformation from Ag to AgCl (which is not photocatalytically active under visible-light irradiation), while Ca2+ at concentrations higher than 50mM (k=-1.3×109M-1s-1) induced aggregation of Ag/AgCl and thus all of them revealed inhibitory effects. In contrast, NO3- (k=6.9×108M-1s-1) and CO32- (k=3.7×108M-1s-1) improved the photocatalytic activity of Ag/AgCl slightly by improving the rate of HO• generation. Other ubiquitous secondary effluent components including SO42- (k=3.9×105M-1s-1), NH3+ (k=3.5×105M-1s-1) and Na+ (k=2.6×104M-1s-1) had negligible effects. 90% of 17-α-ethynylestradiol (EE2) spiked in the secondary effluent was removed within 12min, while the structure and size of Ag/AgCl @ chiral TiO2 nanofibers remained stable. This work may be helpful not only to uncover the photocatalytic mechanism of Ag/AgCl based photocatalyst but also to elucidate the transformation and transportation of Ag and AgCl in natural water

Inkjet-printed microstrip patch antennas realized on textile for wearable applications

This letter introduces a new technique of inkjet printing antennas on textiles. A screen-printed interface layer was used to reduce the surface roughness of the polyester/cotton material that facilitated the printing of a continuous conducting surface. Conducting ink was used to create three inkjet-printed microstrip patch antennas. An efficiency of 53% was achieved for a fully flexible antenna with two layers of ink. Measurements of the antennas bent around a polystyrene cylinder indicated that a second layer of ink improved the robustness to bending. © 2014 IEEE

Social Support, Intimate Partner Violence and Quality of Life among Women Living with HIV in Ruili, China

Women are increasingly burdened with human immunodeficiency virus (HIV) globally at a time when the availability of antiretroviral therapy (ARV) has turned HIV and acquired immune-deficiency syndrome (AIDS) into a chronic condition. Despite a growing literature examining the life of women living with HIV/AIDS (WLHA) in Africa and the western world, much less is known about the experiences of WLHA in Asia. With quality of life (QoL) becoming one of the primary goals of long-term HIV management, data is urgently needed to understand the challenges facing WLHA in settings that differ from the existing body of research. Social support and intimate partner violence (IPV) also have emerged in the scientific literature as core factors influencing the well-being of WLHA, yet they largely remain unexplored within the context of a low resource environment. Migrant women are of special concern because they are at high risk for HIV. Despite the plethora of evidence that cross-border migration elevates the risk of adverse health outcomes among women, little is known about how migration intersects with social support, IPV, and QoL of WLHA. Social support is known to be challenged during acculturation for migrants, poses critical impact on IPV and also has proved instrumental to a better quality of life. How these intersecting outcomes play out among WLHA under the influence of cross-border migration is the question driving this study. This study set out to address the prominent gap in knowledge among a population of WLHA with male partners in Ruili, China, a location where one of the nation’s HIV epicenter meets a population flow that crosses the border from Myanmar into China. The specific study aims are: (1) to assess perceived social support among the WLHA and to see if migration status differentiates the sizes of perceived support, (2) to investigate if and how migration, social support, and a set of partnership variables predict IPV risk among these women, and (3) to evaluate the quality of life among WLHA and how it is associated with migration, social support and IPV

Natural killer T cells: Atherogenic Mechanisms and Therapeutic Targeting

Atherosclerosis is a chronic inflammatory disease of medium and large-sized arteries. The immune system, including innate and adaptive components participates in development and progression of atherosclerosis. Immune cells, including dendritic cells, monocytes/macrophages, CD4/CD8+ T cells, B cells, natural killer cells and natural killer T cells present in both human and mouse atherosclerotic lesion. NKT cells have been shown to be pro-atherogenic in many studies and our group have identified that CD4+ iNKT cells are the NKT cell subset responsible for pro-atherogenic activity. However it is not clear how exactly these NKT cells exert their pro-atherogenic effect and whether NKT cells are therapeutically targeted to improve atherosclerosis.        Adoptive transfer of CD4+ iNKT cells isolated from wild type mice into Rag2-/-Apoe-/- and Rag2-/-γc-/-Apoe-/- mice developed bigger lesions compared to vehicle control mice. It indicated that CD4+ iNKT cells can promote atherosclerosis independently of T, B and NK cells. Ja18-/-Apoe-/- mice, which are deficient only in iNKT cells, were adoptively transferred with CD4+ iNKT cells isolated from wild type or mice selectively deficient in interferon-γ, interleukin-4, interleukin-21, perforin or granzyme B. Compared to wild type and cytokine-deficient NKT cells, cytotoxin-deficient NKT cells failed to promote atherosclerosis in Ja18-/-Apoe-/- mice, suggesting that NKT cells utilise perforin and granzyme B in their atherogenic function. Moreover, smaller necrotic core area and less apoptotic cells were observed in mice that received cytotoxin-deficient NKT cells suggesting NKT cell-induced lesion cell death via cytotoxins.        NKT cells are activated via CD1d-assisted lipid antigen presentation by antigen presenting cells. DPPE-PEG350 (NKT cell antagonist) is a chemical lipid antagonist which blocks NKT cell activation via competeing with lipid antigens in CD1d binding. Thus I investigated whether DPPE-PEG350 can therapeutically prevent NKT cell activation in atherosclerosis. DPPE-PEG350 was administrated into Apoe-/- mice at the beginning of 8-week high fat diet. The lesion size decreased significantly in DPPE-PEG350-treated mice. Also, DPPE-PEG350 treatment reduced necrotic core without affecting the content of smooth muscle cells and collagen. To investigate a potential of DPPE-PEG350 in clinical translation, I designed an experiment where mice with established atherosclerosis were treated with DPPE-PEG350. Apoe-/- mice were fed a high fat diet for 6 weeks to establsih atherosclerosis and then treated with DPPE-PEG350 for another 6 weeks while fed a high fat diet. DPPE-PEG350 treatment attenuated atherosclerosis without affecting smooth muscle cells and collagen and also reduced necrotic core and apoptotic cells. To test whether atherosclerosis reduced by DPPE-PEG350 treatment is via blocking NKT cell activation, DPPE-PEG350-treated mice were challenged with α-GalCer (NKT cell agonist). Strikingly, α-GalCer failed to increase atherosclerosis in mice treated with DPPE-PEG350 compared to mice that received α-GalCer alone, confirming that DPPE-PEG350 treatment ameliorates atherosclerosis via NKT cell-dependent manner.        In conclusion, this study defines the mechanism by which CD4+ iNKT cells promote atherosclerosis. It also shed light on therapeutic potential of DPPE-PEG350 in targeting NKT cells in atherodclerosis and may lead to the finding of novel clinical treatment for atherosclerosis

Genetic diversity analysis of phenotypic traits among 37 <i>Xanthoceras sorbifolium</i> elite germplasms

Xanthoceras sorbifolium is one of the most economically important species cultivated in northern China. To analyze the phenotypic variation within X. sorbifolium, 35 phenotypic traits among 37 elite germplasms were analyzed using nested analysis of variance, coefficient of variation (CVs), principal component analysis (PCA), correlation analysis, and cluster analysis. Large variation and rich phenotypic diversity were found among and within germplasms of X. sorbifolium. The mean of coefficient of variation for 35 traits among 37 germplasms was 25.49%. It varied from 12.80% to 63.25%, and ranked as follows: branch traits (45.51%) > inflorescence traits (31.01%) > fruit traits (24.67%) > flower traits (24.35%) > seed traits (21.82%) > leaf traits (21.45%). The mean heritability (H2) of 35 phenotypic traits was 75.94%. Significant correlations were observed within and among most branch, leaf, inflorescence, flower, fruit, and seed traits. The cumulative contribution rate of the first nine main principle components reached 80.333%. The 35 phenotypic traits were classified into two main categories and five subcategories by clustering analysis of phenotypic traits. Combined result of correlation, PCA, and clustering of phenotypic traits, 18 representative traits were selected. The 37 elite germplasms were classified into two main groups and six subgroups according to their characteristics by Ward’s method and reasonable utilization of each subgroup were suggested. These results provide useful information for genetic improvement, preservation, and evaluation of X. sorbifolium germplasms.</p
