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

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

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

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

We already know a lot about the world around us and, in general terms, understand how things work. Of course, some problems have not yet been solved: the behavior of black holes, the mysteries of quantum entanglement, the transparency of dark matter. It is not clear how life arose from dust. However, we hope to eventually understand everything that we do not yet understand, because we believe in the power of our minds. But the problem of the mind itself stands apart. There is nothing more complex in the world than consciousness. Here we have to comprehend ourselves and it is not entirely obvious that this is possible. Let's say the meat grinder is quite primitive, but she doesn't know it.

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

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

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.
