Determinants of Informal Recycling Behavior among Urban Dwellers in the Kathmandu Valley, Nepal
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
Ecological Risk Assessment of Desalination Plants Discharges on the Marine Environment Red Sea, Egypt
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
Comprehensive Study of Various Chemical Samples in Forensic Toxicology: Focus on Urine Sample
Toxicology deals with the measurement and analysis of toxins. It is itself a vast branch of science, though it has several
branches and one of these is forensic toxicology. Forensic toxicology is a branch of toxicology that lines up with other disciplines, namely clinical chemistry, postmortem forensic toxicology, human performance toxicology and forensic drug testing,
providing medical jurisprudence of adverse effects such as drug abuse, poisoning and death. The key role of forensic toxicology is to identify and analyse the toxin compounds found during adverse events. This review paper aims to draw an idea
about the toxin, in the collected biological chemical samples such as urine samples and their effects on their day-to-day life
Entomological Observations on a Decomposing Pig (Sus scrofa) in Nebraska: Late Spring to Early Summer
The determination of the postmortem interval (PMI) towards assisting in medicolegal investigations is a frequent requirement in any developed jurisdiction. Each of the latter has prevailing peculiarities, especially with many operating variables
that include seasonal changes. There is a dearth of information about the decompositional pattern and progress of cadavers
deposited on the ground in Nebraska, a jurisdiction lying within the Central Great Plains of North America. The present
study, using an experimental pig was designed to consider the entomological peculiarities within a geographical area exhibiting taphonomic characteristics, and during a defined season.

On the Self-Organization of Dielectric Barrier Discharges
The present paper contains experimental analysis of the spatiotemporal structure of atmospheric pressure dielectric barrier
discharge (DBD) in a packet-pulse excitation mode widely used as an effective tool for plasma modification of various media. The motivation is the need to optimize the conditions for DBD plasma obtaining with a homogeneous diffuse structure.
It is shown that for a discharge gap of the millimeter range (1–3 mm) in atmospheric air, under certain conditions, a number of new plasma phenomena are possible - the effects of an increase in the density (total number) of filamentary
discharges over time, both unchanged and with a decrease in the area of the filaments, as well as the formation of complex
space-time structures. An interpretation of this phenomenon is proposed. Homogeneous diffuse discharges are obtained in
a standard electrode configuration with a single dielectric
Pulmonary Congestion Dynamics According to Inter-Dialytic Intervals in Hemodialysis
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
Complex Decongestive Therapy and Additional Physiotherapy in Male Breast Cancer: A Case-Report

The Sensory Attributes Potentiating Effect of Mid-Infrared Rays on Moringa Leaf
Moringa leaf (Moringa oleifera) is referred to as the “natural nutrition of the tropics”, and in the Philippines, as “mothers’
best friend”. It possesses many health benefits and is also used in disease prevention and therapy. The enhancement of
moringa’s natural potency is a scientific challenge that has yet to be thought of. We found enhanced inherent characteristics
in the moringa leaf by irradiating using our recently invented 2-6µm mid-infrared ray generating atomizer (MIRGA). The
achieved benefits were a more desirable taste and aroma, and an enhanced shelf life, thus increasing the potential transportation distance, quality, and palatability. This scientific achievement was supported by suitable instrumentations and sensory
evaluation
Formulation and Evaluation of Clindamycin Peel-Off Gel Face Mask against Acne Vulgaris
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.
The Development of a Classification System for the Treatment of Scoliosis by the Side Shift Approach
The Side Shift approach to correction of scoliosis curves has been used by therapist at the Royal National Orthopaedic Hospital (RNOHT) for over 30 years. The Side Shift approach was developed by Mrs Min Mehta, and has been

The Impact of Seasonal Changes on Growth Performance, Rumen Fermentation, and Rumen Microbiota Structure of Yaks: An Analysis Using the Supplemented 2.5kg Concentrate Level as an Example
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).

Anodizing for Design and Function
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.
Recent Developments in Human Odor Detection Technologies
Human odor detection technologies have drawn attention due to the wide possibility of potential applications they open up in areas such as biometrics, criminal investigation and forensics, search for survivors under rubble, and security checkpoint screening. Gas chromatography/mass spectrometry (GC/MS) has been the most successful and powerful analytical approach developed to date for human odor analysis, and hundreds of human odorants have been identified using this tool.
Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath
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.

polyester, rayon and wool.
The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films
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.
Anodic Oxidation of Titanium in Sulphuric Acid and Phosphoric Acid Electrolytes
Anodisation of pure titanium has been carried out in sulphuric and in phosphoric acid solutions at potentials ranging from 50 to 150V. The SEM and AFM morphological analysis indicates that, within this potential range, oxidation in sulphuric acid solution produces better developed mesoporous oxide layers.
