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.
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
Maize is an economically important crop worldwide. As the world population increases, there is a great need to develop
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.
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

Linear Support Vector Machine Myoelectric Pattern Recognition Control System Architecture for Transtibial Osteomyoplastic Amputees
The use of surface electromyography (sEMG) signals for clinical diagnosis is well appreciated in the medical
field. However, the use of sEMG signals for the control of powered prosthetic limbs is still regarded as a futuristic idea. Past
and present studies have focused more on the upper limb (hand) as compared to the lower limb (leg). The challenges associated with the controlling leg movement include designing for both balance and locomotion. After amputation, the muscle
orientation and alignments on the residual stump changes as some of the anatomical landmarks are changed during surgical
procedure. To achieve locomotion, some amputees, generally from third-world nations, use passive mechanical prosthetic
limbs with a fixed ankle.

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.

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.
