: The recent review conversed about nano-technology. Nanotechnology is very important in the diagnosis and detection of disease, as nanotechnology is the fifth generation that appeared in the world of electronics, the first generation represented in the use of the electronic lamp, including television, then the discovery of the transistor, and the spread of its wide applications and then the use of integrated circuits, which is a very small piece. Nanotechnology today has reduced the size of many devices, increased their efficiency and numbered their functions. Then the microprocessor, which made a huge revolution in the field of electronics by producing personal computers and silicon chips, and then nanotechnology. Nano-size as the material is made by light etching, cutting, scraping and grinding.

Batch experiments were carried out for the adsorption of Janus Green B (JGB) onto walnut kernel shell particle. walnut kernel shell treated with burn in 300 C0 was tested as a low cost adsorbent for the removal of Janus Green B from aqueous solution . The effects of various experimental parameters, such as adsorbent dosage and particle size, initial dye concentration, pH and contact time, were investigated in batch mode . An amount of 1.5 g/l of (WKSC) could remove 99.36 % of the dye from an aqueous solution of 50 ppm with the agitation time 150 min and particle size 75 mm and with acid medium (pH=2) . The well Known Langmuir and Freundlich isotherm models were applied for the equilibrium adsorption data and the various isotherm parameters were evaluated. The results indicate that activated walnut kernel shell carbon (WKSC) could be employed as a low cost alternative to commercial activated carbon in wastewater treatment for the removal of color and dyes

A simple, rapid, inexpensive, and eco-friendly flow injection system is designed for the determination of Bismarck Brown R dye. The design process is included the manufactureof dual flow injection valve with the possibility of loading one solution. The flow rate of carrier stream, optimum volume of sample, repeatability, and dispersion coefficient are studied. The calibration graph is constructed for both spectrophotometric and flow injection methods. The flow rate is fixed at 2.10 mL.min-1 with optimal volume 157.00μL of Bismarck Brown R dye. The repeatability is conducted for 10 measurements (n=10) and the dispersion coefficient values are 1.75 and 1.58 for the concentrations 5.00 ppm and 7.00 ppm respectively. The linear range of calibration graph is (0.05-35.00) ppm for flow injection method and (0.10-25.00) ppm for spectrophotometric method. The flow injection method is successfully applied for the determination of Bismarck Brown R dye in standard solutions.

The research is included determination of Fe(II) via its reaction with 1,10-phenanethroline to form light-red complex which is absorbed at λmax=510 nm. Home-made flow injection valve is designed with two loading loops, L1 and L2. A series of studies are conducted represented by fixing physical and chemical optimum conditions, dead volume, repeatability, dispersion coefficient, construction calibration graph, and application of the method. The dead volume is zero for the system which it has high repeatability (n=8) with RSD and SD 0.6 and 0.05 respectively. The dispersion coefficient is 1.68 at the concentration 10 ppm. The range of measurements of calibration graph is (0.05-18.00) ppm with limit of detection (S/N=3) 0.05 ppm.

The research is included studying and designing micro flow injection system which is characterized with rapidity, simplicity, and low cost for the determination of green malachite dye. The study of flow rate of carrier stream, repeatability, dispersion coefficient, and calibration graph are conducted. It is found that the optimum conditions for the determination of mentioned dye are flow rate 4.200 mL/min, sampling rate 102 sample/h, limit of detection 0.05 ppm, linear range (0.05-18.00) ppm with linearity (R2 = 0.9700), RSD is 0.355, the repeatability for seven successive injections is studied for the two concentrations 5 ppm and 12 ppm, and the dispersion coefficient values are 1.73 and 1.28 at the two concentrations 2 ppm and 9 ppm respectively.

A safety data sheet (SDS), material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products. SDSs are a widely used system for cataloguing information on chemicals, chemical compounds, and chemical mixtures. SDS information may include instructions for the safe use and potential hazards associated with a particular material or product, along with spill-handling procedures.

The Kufa Journal for Nursing Sciences-KJNS was accepted into the WHO index of medical journals after four months of successful efforts and the approval of the WHO office in the Eastern Mediterranean Region (IMEMR) to be among 950 medical journals. Since 1986, the Regional Office for the Eastern Mediterranean aims to provide comprehensive bibliographic control, abstracting, and indexing services for all health and medical journals published in the Region. As well as access to the index, a document delivery service has also been activated which will enable any user to obtain a copy of any article included in “Index Medicus for the Eastern Mediterranean Region- IMEMR” for free.
