Study and Characterization of Non- linear Optical Properties of ZnS nanobelts

In this work, first we synthesized the nanobelts semiconductor ((ZnS manufactured through a chemical evaporation deposition (CVD). the films obtained diagnosed through x-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscope (SEM), was a study of non-linear optical properties. in comparison with the optical microscope, confocal microscope optical measurements, measurements of second harmonic generation  using Ti : Sappire laser femto second (800nm), showed that nanobelts ZnS prepared, had a  Blue emission at a wavelength 400 nm, which can be attributed to the deep-level emissions resulting from defects or impurities

Second- harmonic generation improved of hybrid nanostructures

We provide the synthesis and characterization of semiconductor nanowire attached with metallic nanoparticles. The wires consist of zinc sulfide (ZnS) attached with gold nanoparticles (Au NPs). The nonlinear optical properties of the semiconductor nanowires are combined with the plasmonic of metallic nanoparticles (Au NPs) and offer an improved optical signal in the near infrared spectral range. The plasmonic of a metallic (Au NPs) offers the effect of locally improving the electric field of the incident light on the nanowire and consequently inducing a much stronger second harmonic generation (SHG) signal. By comparing SHG signals measured from bare ZnS NWs  and  ZnS –Au hybrid nanostructures we obtain  6 time improvement of the SHG intensity It is demonstrated that is ZnS NWs is an ideal candidate for nanolasers, nanoprobes especially for the ultraviolet region, nonlinear optical microscopy and nanophotonic. Keywords: plasmonic nanostructures. Chemical synthesis, ZnS NWs,  Second - Harmonic generation (SHG)

Mismatch between school furniture and anthropometric measurements of primary school children in Mersing, Johor, Malaysia.

This study is a cross-sectional study with the objective to determine mismatch between school furniture and anthropometric measurement among primary school children in Mersing. The sample consisted of 91 primary school children (46 male and 45 female) from Year 2 and Year 5 in two schools in Mersing District, Malaysia. Seven anthropometric measurement (height, weight, popliteal height, buttock-popliteal length, hip breadth, shoulder height and elbow height while sitting) as well as 5 furniture dimensions (seat height, seat depth, seat width, backrest height and seat to desk height) were taken. Instruments used were Martyn type anthropometer set, ruler, height scale and weighing scale. Differences between genders in anthropometric measurements were also investigated in this study. Findings showed 100% high mismatch for seat height, seat depth, desk height respectively while 56% match and only 44% mismatch for backrest height among Year 2 children. Year 5 students reported contrary result with 79% mismatch for seat height, 91% for backrest height and 100% for both seat depth and desk height. There was no significant difference between genders for both age groups. In conclusion, there was a mismatch between furniture and children's anthropometric measurements. It is recommended that school furniture be redesigned so as to conform to the children's physiological measurement. The use of adjustable furniture can be taken into consideration in designing new furniture for school environments in order to meet all the differences in children anthropometry

In vitro cytotoxic study for partially purified Lasparaginase from fresh leaves, unripe and ripe fruits of Withania somnifera plant

This work aimed to study the cytotoxic effect of L-asparaginase isolated from local Withania somnifera plant on lymphocyte leukemia cells. To achieve this goal, L-asparaginase was purified from W. somnifera fruits by two purification steps, ion-exchange chromatography using DEAE-cellulose and gel filtration chromatography using Sephadex G-150, and the study utilized an in vitro evaluation for the cytotoxic effect of the partially purified L-asparaginase with concentrations ranging (12.5 to 100 μg/ml) in a two fold serial dilutions on some cell suspension culture including, acute lymphocyte leukemia and chronic lymphocyte leukemia culture at different concentrations (12.5 to 100 μg/ml) and different exposure time of treatment (24, 48 and 72 h). This two purification steps raised the specific activity from 1.73 U/mg in crude extract to 2.29 U/mg after ion-exchange and 10.5 U/mg after gel filtration; the purification fold was 1.32 after ion-exchange and 6.06 after gel filtration, the enzyme recovery was 56% after two purification steps and the results, pointed that acute lymphocyte leukemia culture showed highest sensitivity toward the cytotoxic effect (62.3±0.9%) of the partial purified L-asparaginase (100 μg/ml) than other culture after 48 h in a dose dependent manner, and highest cytotoxic inhibitory effect (73.2±1.6%) after 48 h of exposure on chronic lymphocyte leukemia culture, while healthy lymphocyte culture showed novel behavior. The lowest concentration of cell treatment gave the most significant (P&lt; 0.01) inhibitory effect. The conclusion is that there is enough evidence to support the claim that Lasparaginase from W. somnifera may be considered chemotherapeutic agent against cancer, such as acute lymphoblastic leukemia and lymphosarcoma.Keywords: Acute lymphocyte leukemia (ALL), chronic lymphocyte leukemia (CLL), L-asparaginase, cytotoxic assay

Deep Desulfurization of Diesel Fuel by Guard Bed Adsorption of Activated Carbon and Locally Prepared Cu-Y Zeolite

Desulfurization of a simulated diesel fuel by different adsorbents was studied in a fixed-bed adsorption process operated at ambient temperature and pressure.  Three different adsorption beds were used, commercial activated carbon, Cu-Y zeolite, and layered bed of 15wt% activated carbon followed by Cu-Y zeolite.Initially Y-zeolite was prepared from Iraqi rice husk and then impregnated with copper. In general, the adsorbents tested for total sulfur adsorption capacity at break through followed the order Ac/Cu-Y zeolite>Cu-Y zeolite>Ac. The best adsorbent, Ac/Cu-Y zeolite is capable of producing more than 30 cm3 of simulated diesel fuel per gram of adsorbent with a weighted average content of 5 ppm-S, while Cu-Y zeolite producing of about 20 cm3 of diesel fuel per gram of adsorbent with a weighted average content of 2ppm-S. Activated carbon breaks through almost immediately

Karakteristik sifat fisikokimia sabun cuci cair menggunakan sari lerak sebagai surfaktan alami

Lerak (Sapindus rarak Dc.) is an Asian plant that produces saponins, artificial surfactant, used as cleaning agent. Lerak has been used as traditional cleaning product because it is believed to maintain the color of the product, and also eco-friendly. The use of lerak as a traditional cleaning product is inefficient, so in this study lerak will processed as liquid laundry soap. This study conducted to determine the effect of lerak concentration (5 %, 7 % and 9 %) to the physicochemical properties of liquid laundry soap. This study used Randomized Block Design (RBD), analyzed by one way ANOVA and the next test used LSD test. Based on the research, lerak concentration were significantly different on pH, free fatty acids and clean ability of liquid laundry soap but were not significantly different on specific gravity, viscosity, foam stability of liquid laundry soap. The best treatment is liquid laundry soap with 7 % lerak concentration that have higher values of clean ability and viscosity. The addition of lerak concentration in liquid laundry is proven to increase their cleaning power and eco-friendly but will be constant at saturated level

ASPEK-ASPEK YANG MEMPENGARUHI AKHLAK SERTA AKTUALISASI DALAM KEHIDUPAN SEHARI-HARI

The importance of understanding these human factors becomes especially clear when we consider the role of humans as moral agents. Human activities are greatly influenced by the environment and surrounding conditions. Therefore, we must study the most important factors that shape and influence human behavior as well as its actualization in everyday life, such as morals towards Allah, morals towards fellow humans and morals towards the environment. The five factors discussed in this text are habits or customs, instincts or instincts, environment, education and media
