Peat land covers a large portion of the total land area in Malaysia and several other countries throughout the world. The Malaysian state of Sarawak has the most peat land area nationally. Peat is ...considered a problematic type of soil due to its high compressibility, high moisture content, high organic matter and low shear strength. As a form of stabilization, it is suggested to combine palm oil fuel ash (POFA) with peat. This study investigated the engineering properties of these composite matrices in terms of the California Bearing Ratio (CBR) and Standard Proctor test values. Results showed that the dry density of the peat samples increased with the increase in POFA content. The POFA-peat composites showed an increase of 4 times the untreated peat value. Also, CBR values for these composites increased from 31 to 42 fold, in comparison with untreated peat. The peat-POFA CBR values are rated as good materials for the purpose of road base or subbase construction.

The azo reagent 3-((benzothiazol-2-diazenylnaphthalene-2,7-diol was synthesized and characterized by FT-IR, 1H-NMR and 13CNMR spectral techniques. The electrochemical behavior of the azo reagent and ...its complex with Fe (III) has been studied at glassy carbon disk GCE electrode in different supporting electrolyte at concentration (1M) and scan rate (100mvs-1). Spectrophotometric determination of Iron (III ) is based on the formation of a 2:1 complex with above reagent. The complex has λmax at (576) nm and εmax of( 1.6451*104)L.mol-1.cm-1. A linear correlation (0.1 - 4.0 μg. ml-1) was found between absorbance at λmax and concentration. The effect of diverse ions on the determination of Iron (III) to investigate the selectivity of the method were also studied. The stability constant of the product was (3.098*108 ). The proposed method was successfully applied to the analysis of blood samples
The study included follow-up of the interaction of the prepared reagent 1- (4 -Anti-pyrail-Azo) 2- naphthol (APANOL) with vanadium (V) ion, which gave a greater wavelength of absorption (533) nm as ...well as a study of the best conditions of the size and concentration of the reagent (1 × 10-3) molar and acidic function (pH = 3) and the stability of the complex for more than two hours and temperature from 10 to 40 degrees Celsius and the linearity range falls within the concentrations (0.10-4.00) ppm and correlation coefficient (R2 = 0.9945) and the value of molar absorption coefficient ε (1.02 x 104) l. Mol-1 cm-1 and sandal allergy (0.004) micrograms cm-2. And determined the accuracy and accuracy of the analytical method followed using standard solutions of ion with a standard concentration of the reagent, so the frequency (RSD %) with respect to concentrations (2.00, 3.00) ppm of vanadium ion (V) equal to (0.9 and 0.9), Erel. %) Was equal to (0.2, 0.3) %
Cross-Site Scripting (XSS) is one of the most common and dangerous attacks. The user is the target of an XSS attack, but the attacker gains access to the user by exploiting an XSS vulnerability in a ...web application as Bridge. There are three types of XSS attacks: Reflected, Stored, and Dom-based. This paper focuses on the Stored-XSS attack, which is the most dangerous of the three. In Stored-XSS, the attacker injects a malicious script into the web application and saves it in the website repository.
The proposed method in this paper has been suggested to detect and prevent the Stored-XSS. The prevent Stored-XSS Server (PSS) was proposed as a server to test and sanitize the input to web applications before saving it in the database. Any user input must be checked to see if it contains a malicious script, and if so, the input must be sanitized and saved in the database instead of the harmful input. The PSS is tested using a vulnerable open-source web application and succeeds in detection by determining the harmful script within the input and prevent the attack by sterilized the input with an average time of 0.3 seconds.

Biological contaminants refer to environmental contamination and food source with living microorganisms such as bacteria, molds, viruses, and fungi, in addition to mites, house dust, and pollen. ...Temperature, relative humidity, movement of air, and sources of nutrients have influenced the presence and spread of biological contaminants. Numerous living microorganisms can grow independently on each other, such as bacteria and fungi. Viruses (a small obligate parasite) depend on other living organisms for their development and for performing vital functions. Indoor air can contaminate with biological contaminants by a different status, including living, dead, or debris of the dead microorganisms which were transported through ventilation systems, when the microorganism components dissolve in water. They become aerosolized when the contaminants are physically disturbed, like in renovation or construction, and when the contaminants discharge harmful gases into the indoor environment. Most studies conducted in recent years agree that air pollution rates are increasing, bringing more risks to human health, as pollution is related to the risk of heart and lung disease and its effect on children, especially infants and newborns. Also, environmental pollution may have become the most dangerous disaster faced by humans, because it means environment retrogradation in which humans lives as a result of an imbalance within the compatibility of the constituent elements and loses its ability to carry out its natural role in self-removal of contaminants by the natural factors noticeable within air, land, and water. In some cases, many common infections can spread through airborne contaminated microorganisms such as Mycobacterium tuberculosis, measles virus (MV), influenza virus, Morbillivirus, chickenpox virus, norovirus, enterovirus, less commonly coronavirus, adenovirus, and respiratory syncytial virus (RSV). When an infected person coughs, talks, sneezes, has throat secretions, and releases nasal into the air, the airborne infection can spread. Bacteria or viruses spread out noticeably in the air or ground and transport to other persons or surfaces. This review provides the conception of biological contaminants and their properties, nature of the indoor environment, and adverse health effects associated with biological contaminants.
