Recycling is an important tool to cope with and sustainably manage rapidly increasing waste generation, and promoting local practices such as informal recycling is vital in developing countries. is study identies determinants of informal recycling that residents of Kathmandu Valley, Nepal practice by selling the recyclable waste to scrap dealers. e data comes from a households survey conducted with around 1200 households in the Valley in 2012. Informal recycling is important because it complements inecient and expensive waste collection services, diverts waste from the landll site, and helps the city to develop sustainably. We found that people who compost are 11.8 to 12.8 percent more likely to recycle in comp

Desalination has become one of the main alternatives to compensate for water shortages. Although seawater desalination is expensive and has many environmental risks, it is still an important option to compensate for water shortages in Egypt. The discharge of liquid waste (especially heavy metals) from the station into the sea has a negative impact on the water, so the spatial distribution of heavy metals (lead, cadmium, and copper) shows high concentrations near the outlets of both AlQusayr and the port of Al-Qusayr. Hamata desalination plants in the southern Red Sea. As for higher quantities of heavy metals - higher than the standard values - such as (Cu, Pb, Cd), they are classified as seawater pollutants, whether they show evidence of toxicity or not. The study demonstrated that seaweed has bio-absorption properties and can effectively absorb heavy metals from the surrounding water, and thus it can serve as a bio-indicator in tools for monitoring the degree of pollution, as well as evaluating water desalination activities

Lung ultrasound (LUS) is reliable in detecting and quantifying of pulmonary congestion in hemodialysis (HD) patients. Pulmonary congestion holds a negative prognostic value in HD patients even when it is asymptomatic. The pathophysiology of pulmonary congestion in HD is complex and includes volume and non-volume dependant factors. We examined the impact of different inter-dialytic intervals on pulmonary congestion by studying its dynamics using lung ultrasou

Intravascular large B-cell lymphoma (IVBCL) is a rare but aggressive form of non-Hodgkin lymphoma. It is characterized by the malignant proliferation of lymphocytic tumor cells in the lumens of capillaries, small arterioles, and post-capillary venules. There exists two clinical variants: the Asian variant and the Western variant. The former is associated with neurologic and dermatologic signs and symptoms, whereas the latter often presents with splenomegaly, jaundice, and hemophagocytes. Lymphadenopathy is uncommon, and patients typically have nonspecific symptom

Anaplasma marginale is the etiological agent of bovine anaplasmosis, one of the most prevalent tick-borne diseases of cattle in tropical and subtropical regions that causes significant economic losses to cattle industry. Cattle that survive infection remain persistently infected for life. Immunity against A. marginale infection seems to require both humoral and cellular mechanisms. Antibodies against A. marginale neutralize bacteria by interacting with Major Surface Proteins (MSPs). For this reason, MSPs are believed to be one of the best candidate antigens for vaccine development. Research carried out in the last few years has helped us to understand the antigenic composition of A. marginale and to develop new potential vaccine formulations. Desirable bovine anaplasmosis vaccine must induce protective immunity as well as prevent infection and transmission

The main aim of this project is to formulate and evaluate Clindamycin peel-off gel face mask against Acne vulgaris. Peel off gel mask of Clindamycin phosphate was formulated using different excipients like Triethanolamine, Carbopol, Polyvinyl Alcohol, Glycerine, Xanthan gum, and Benzyl alcohol. Formulation of different composition of polymer was formulated and their pH, extrudability, homogeneity, spreadability, viscosity, washability and other parameters like drug content, permeability and drug release were evaluated. The result showed that the concentration of PVA and Carbopol which are the main polymers used in the formulations had effect on the drug content, drug release, permeability, spreadability and other parameters. The peel off mask prepared by using different concentration of these two polymers showed satisfactory result in all the evaluated parameters.

A trial was carried out on growing lambs to compare conventional protein supplementation of sugarcane with soybean meal with Saccharomyces cerevisiae enrichment produced by solid-state fermentation. Yeast enrichment enabled sugarcane stalks to increase their crude protein content from 4% to 12%. No difference was obtained between these two forms of supplementation on the daily growth of 80.2 and 76.8 g per day for enriched and non-enriched sugarcane respectively.

The study investigated the effects of supplementing the same level of concentrate in different seasons on the growth performance, rumen fermentation, serum biochemical index, and rumen microflora changes in yaks, to provide guidance on accurate feeding of yaks in cold and warm seasons. 12 healthy yaks weighing (124.21±15.64) kg were selected for the experiment, with a warm season group from August to October and a Cold season supplemental feeding group from October to December. The results showed that the mean daily gain was significantly higher in the warm season grazing group than in the cold season grazing group (p<0.05). Rumen fermentation, serum biochemical index, and rumen microflora changes also varied significantly between the two groups (p<0.05).

The results are presented of obtaining anodic aluminum oxide with an ordered pore arrangement by employing two anodizing modes - galvanostatic mode and combined (galvanostatic + potentiostatic) mode, at high values of the current density and voltage. Use has been made of an oxalate electrolyte and a complex electrolyte comprising oxalic acid and phosphoric acid. Scanning electron microscopy has been used to investigate the surface morphology of the barrier and porous layers and to determine pore sizes and inter-pore distance.

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.

In this paper, we report on the synthesis of BaTiO3 nanowires via the anodic aluminum oxide template method. To fill in the precursors of BaTiO3 into anodic aluminum oxide templates, the vacuum and drop loading method developed in our previous study was used. Ba(CH3COO)2 (barium acetate) and C12H28O4Ti (tetraisopropyl orthotitanate) were used as Ba and Ti sources, respectively. Anodic aluminum oxide membranes with the through-hole diameter of ~200 nm were used as the template for BaTiO3 nanowires.
