Prevalence and Risk factors of Stunting and Wasting among Under-Five-Aged Children in North Gondar Zone, Northern Ethiopia
Undernutrition is a leading cause of disease susceptibility, morbidity, and mortality in children. It is manifested in the form
of stunting and wasting. Wasting is an acute form of undernutrition that indicates a recent food shortage and/or infectious
diseases that lead to rapid and severe weight loss. The current study aimed to assess the prevalence and associated factors of
stunting and wasting among under-five-aged children of displaced families in the North Gondar Zone. A cross-sectional
study design was conducted from January to March 2022 among the under-five-aged children of the displaced family. A total of 205 randomly selected under-five-aged children from the displaced families were included in the study. A structured
questionnaire was used to collect data, and the instrument was adopted from a previous study. Anthropometric measurements were carried out to determine the status of stunting and wasting. A bivariable and multivariable logistic regression
analysis was used to find the factors associated with stunting and wasting. The prevalence of stunting and wasting among under-five-aged children was 26.2% and 18.7%, respectively. Out of the risk factors considered in the present study, age (AOR
= 3.54; 95% CI: 0.2–3.54), family monthly income (AOR = 3.6; 95% CI: 1.3–7.5), eating only two meals per day (AOR = 2.8;
95% CI: 1.0–6.2), and not eating farm animal products (AOR = 2.2; 95% CI: 0.5–1.61) were important risk factors associated
with stunting. In the other way, age, family monthly income, and eating only two meals per day were significant predictors
of wasting. The result showed that the prevalence is severe in the study area. Therefore, the government should work on children under two years of age, take action to solve the nutritional issues, and encourage families with low monthly incomes to
eat animal products at least once a week and nutritious food at least three times a day
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.
Transboundary Water Pollution in Ghana: Addressing the Environmental Footprint of Illegal Mining through Legal and Policy Solutions

Sigmoid Vaginoplasty in Patient with Complete Androgen Insensitivity: Technique and Outcomes
Androgen Insensitivity Syndrome (AIS), also known as testicular feminization, is a rare medical condition that has garnered increased attention in recent years due to evolving research and therapeutic approaches [1,2], as well as the psychological repercussions it has on patients and the risk of being associated not only with sex cord–stromal tumors but also with rare mesenchymal tumors [3]. AIS results from anomalies in the X chromosome and leads individuals with an XY genotype to exhibit various degrees
of female physical traits or complete feminine characteristics
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
In-vitro Regeneration in Maize (Zea Mays L.) from Mature Embryo

high yielding and stress resistant maize varieties. To provide a future platform for maize improvement, we tested mature embryos as alternative explants for the regeneration of three economically important maize inbred lines: CML331, CML442
and CML444.
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
Haosmc Growth on Various Sustainable Nano/Micropatterned Surface Topographies Utilising Reusable Surface Templatin
The aim of controlling/regulating cellular processes by surface patterning of biomaterials is a crucial concept in emerging research fields, where the precise fabrication of micro-nano surface topographies is required at manufacturing scales to meet
consumer demand. Photolithography is typically employed for surface patterning; however, the high cost, process complexity, and lack of environmentally friendly and sustainable methodologies represent steep barriers for many researchers. Soft
lithographic methods have been utilised extensively as a potential alternative for traditional photolithography, yet a photolithographic step is still required for initial template fabrication. Here, we demonstrate the use of repurposed optical consumer items such as DVDs, diffraction glasses, and gratings that would otherwise be thrown away after their useful lives, being used here as a sustainable approach as templates for the formation of complex nano-patterns. By replicating these templates in polydimethylsiloxane (PDMS) and polylactic acid (PLA), we show the varied interactions of human aortic smooth
muscle cells (HAoSMC) to these surfaces. Notably, it was demonstrated that, in comparison to nonpatterned substrates,
HAoSMC interaction (adhesion, spreading, and viability) was higher on DVD patterned surfaces compared to diffraction
glass and grating patterned surfaces according to the results from cell metabolic activity (MTT and Alamar Blue), and proliferation (total DNA) assays. We demonstrate that a simple, reusable, inexpensive, yet robust technology could be a powerful
tool in improving our understanding of cell-surface interactions and for the potential development of medical devices with
micro- and nanoscale low or high adhesion features
Intravascular Large B-Cell Lymphoma, an Updated Review
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
Introduction to the special issue on ‘Nanostructures by Valve Metal Anodization’
With this special issue of JMSN we are pleased to present significant contributions to a fascinating topic in the field of materials nanostructing, which is the anodization of valve metals. By this treatment porous oxides of controlled geometry can be grown on the respective metal surfaces. To date, aluminum (Al) has been used most often, as confirmed in this special issue where nine out of ten contributions deals with its anodization.

Anodic Porous Alumina Array for Cyanine Fluorophore Cy3 Confinement
Self-organized anodic porous alumina films with hexagonal pore lattice have attracted a considerable attention for biological arrays and confinement of various organic probes dyes in solutions. A molecular structure with axial symmetry in bis-heterocyclic indole chains and conjugate system, such as cyanine fluorophore Cy3 dye, was investigated here with respect to its fluorescence when loaded in the anodic alumina pores.
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

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
