Authors: Kamil Jassim Hassan , Gassab Mohammed Mayada , Ali Eaued Hossein
Published: November 2020

In this paper, we apply a new technique, namely fractional Sumudu homotopy analysis method (FSHAM) on fractional partial differential equations to obtain the analytical approximate solutions. The fractional derivative is described in the Caputo sense. This method is the combination of the Sumudu transform (ST) and homotopy analysis method (HAM). The method in general is easy to implement and yields good results. Illustrative examples are included to demonstrate the validity and applicability of the new technique.

Review on analysis of interesting whitening agents in cosmetics products
Authors: Hameed Gatea Azhar
Published: November 2020

The skin whitening as known as skin lightening or skin bleaching is the most commonly used skincare treatment that helps to achieve a lighter and healthier skin complexion by reducing the melanin concentration in the skin in the practice of using chemical products. Several chemicals are effective in skin whitening, while some of them are toxic or have problematic safety profiles. The products requiring to contain either kind of whiting agents were seen to display labeling issues. Such an elevated number of differences suggested concerns of whether such differences between stated and revealed content of whiting agents. The Analytical chemical measurements of these objects look necessary, no reliable analytical methods have been recorded to determine most of these chemicals. Just the measurement of hydroquinone and some of its ethers is treated by a method registered by the European Commission.
Scalp hair as a screening tool for detecting trace elements concentration
Authors: Kadhim Fadhil Ayad
Published: November 2020

Health issues associated with critical trace elements that arise from insufficient (i.e. poor intake) and over-exposure. Measuring sensitivity is also a major problem for geneticists. Among noninvasive assays designed to quantify long-standing exposure to critical trace elements, scalp hair could be the most theoretically biological network. This analysis collects recent information relating to the safety of the scalp as a critical predictor of sensitivity to trace minerals such as cobalt, copper, boron, manganese, iron, selenium, molybdenum, silicon, zinc and vanadium. Particular consideration has been given to the exposure period through which the hair of the scalp is represented, and to the human variation of exposure rates over time in this matrix and the association between scalp hair and other essential markers, human characteristics and environmental influences. Where conventional and contemporary methods of washing and digesting scalp samples have been tested to train models for the measuring of trace metals in the scalp hair. The emergence of different approaches and new analytical procedures has made the usage of other less intrusive or noninvasive matrixes, for example hair. The existence of a chemical in these matrices indicates toxicity; however, associations between blood and the levels of non-invasive media must be established in order to insure that these quantities are associated to the total body load. The development of unique biomarkers which can be tested in this matrix would enhance non-invasive bio monitoring. Common spectral techniques such as inductively coupled plasma mass spectrometry "ICP-MS", plasma spectroscopy laser ablation "LA-ICP-MS", atomic absorption spectroscopy, etc. They have very good analytical performance, but the samples in them are subject to significant damage or are destroyed in addition to being environmentally hazardous because they require the use of hazardous chemicals and take a relatively long time. Compared to the laser induced breakdown spectroscopy "LIBS" process we find that this process has several advantages, such as the flexibility and smallness of the device and the convenience of sample preparation, as well as the ability to analyze samples from a distance, particularly in hazardous and inaccessible places.

In Some binary methanol mixtures, (MeOH), 1,2 dichloroethane (DCE), acetonitrile (AN), and tetrahydrofuran (THF), with dimethylformamide (DMF) at different temperatures using the conductometric process, the reaction of macrocyclic ligand to complexation, dibenzyl-14-crown-4 (DB14C4) with ZrO2+ cation was examined. The conductance data show that in all solvent systems, the stoichiometry of the complex formed between (DB14C4) and ZrO2+ cation is 1:1 (M:L). The stability order of (DB 14C4.ZrO)2+complex in pure non-aqueous solvents was found to be: [AN], [DCE], [MeOH], [THF], [DMF]. A non-linear behaviour was observed improvements in log Kf of (DB14C4.ZrO)2+ complex or Binary mixed solvent composition, It Was clarified as to the Interactions with solvents and even solvents in terms of the hetero-selective solving of the ecosystem affected by complexation response. The obtained results show that the stability of (DB14C4.ZrO)2+ complex is sensitive to the composition of the mixed solvent. The values of thermodynamic parameters ΔH°cand ΔS°c) for the formation of (DB14C4.ZrO)2+complex using van’t Hoff maps, the stability constant was obtained from temperature dependence. The results show that in most cases, the (DB 14C4.ZrO)2+complex is enthalpy destabilized but entropy balanced and the values and signs of thermodynamic parameters are often These are decided by nature and composition of the mixed solvents.

Some physical and chemical variable of this river in water (water Temp., pH, Salinity, DO, BOD5) were measured in the study area, also total organic carbon was measured and the result expressed as a percentage. The high water temperature was recorded (17.00 °C in winter to 26.33 °C in summer), pH (7.44 to 7.73) and salinity (0.66 to 1.66)ppt, DO(7.06 to 3.07), BOD5 (4.34 to 2.91). Also, all the Heavy elements recorded a significant increase in water and Ceratophyllin demersum plant samples in the winter higher than summer and in the sediments and Phragmites australis plant the rise in the winter was only in the elements nickel and zinc, but in cadmium and lead were concentration low or do not make a big difference in the winter compared to the summer. Where there is a positive relationship between the increase in concentrations of Heavy elements in the samples studied and increase in the amount of rain, speed of runoff and the rise in water level in the river in winter due to the volume of rising smoke as a result of pollution which descends during the rainfall and erosion of the edges of the river and lack of control over the domestic sewage that has been brought into the river. As well as probable cause to exist Al-Gharraf oil field that newly established and located north of Fajr city, was considered a control station and opposite to the Qal’at Sukkar city and south of Al-Rifai city we can be observed through the results which show a gradual rise in the second and third stations and the third station was higher than stations 1 and 2.

Published: November 2020

Bacterial lipases are a highly versatile class of hydrolytic enzymes which catalyze the hydrolysis of triglycerol to glycerol and fatty acids. They play an important role in biotechnological and industrial processes, including oleo chemical, food, pharmaceutical detergent formulation, cosmetic, leather, textile, and paper industries applications. Tremendous interest among scientists and industrialists has been arisen in the last decade in microbial lipases due to their versatility and ease of mass production.

In the current work, natural oils such as Triglyceride, Tween 20, Tween 80, Olive oil, Sweet almond, Celery oil, Sesame, Rosemary oils were implemented to enhance lipase production by soil and pathogenic bacterial isolates. Results revealed that triglyceride and tween 80 had the best enhancing activity for lipase production in most isolates. It was also shown that Pseudomonas and Bacillus were the most potential lipase producing bacteria.

A novel modified tributary agar was prepared by the addition of Sudan blue dye and used for the detection of lipase producers. It was shown to give a very clear zone even in the case of weak producing strains as compared to the original medium.

Specific lipase activity had been determined Staphylococcus aureus (in the present research. The highest lipase activity was demonstrated by Pseudomonas (4.5u/ml), while Staphylococcus aureus did not show any lipase activity.

However, a sharp (P < 0.0001) decline of the total serum vitamin D3 concentration were observed in those Najdi sheep per-administration (21.95 ± 1.82 ng/ml) and postadministration (22.29 ± 1.34 ng/ml) of vitamins therapy contrast to control healthy Najdi sheep (89.75 ± 6.84 ng/ml). An interaction between vitamin D3 status and the serum concentrations of calcium/phosphorus, PTH, ALP and ALT was observed. With vitamin D3-deficient Najdi sheep; values of CBC, and calcium/phosphorus concentrations were lower while PTH, ALP and ALT were higher than the healthy control Najdi sheep; thus, no significant changes (P > 0.05) of these values were recorded post treatment of (VITOL-80 C ORAL®). In conclusion, vitamin D3 deficiency threats the health of local Najdi sheep and has a potential role through suppressing their immunity. Oral administration of the commercial product as a source of vitamin D3 is not effective suggesting involvement of vitamin D receptors (VDR) and/or dysfunction of liver and kidneys.

Published: November 2020

Z-scan has been utilized for studying the non-linear properties and optical limiting behaviors of the dye Copper Phthalocyanine thin films. The refractive index is negative, which indicates a self-defocusing behavior and non-linear absorption coefficient (β) of CuPc is a positive sign is a result of RSA. The optical switching behaviors of dye have been researched with the use of the method of the pump-probe with 9ns Q-Switched Nd: YAG laser at pump beam equal to 532 nm and a probe beam equal to 630nm Diode laser. The thin films of copper Phthalocyanine also reflect a significant limiting of the optical power of CW laser with an adequate threshold of the optical limiting. The dye’s switching behavior is a result of the probe beam’s excited-state absorption (ESA) with the molecules of the dye. The modulation of the probe beam with the increase of intensity of the pump has been researched as well.

Published: November 2020

BACKGROUND: One of the most accurate and highly reproducible techniques is dual- energy x-ray absorptiometry (DXA). DXA device used to measure BMD, BMC, T-score, Z-score, and consequently used to measure fat mass (FM) and lean mass (LM) for different body sites such as arms, ribs, thoracic spine, lumbar spine, pelvis, legs and whole body. DXA technique is widely used in clinical application researches like diagnosing and treating osteoporosis in elderly men and women with different diseases and assessment of skeleton status.

METHODS: One hundred and seventy-six males and females participated in the current study consisting of 48 males and 128 females were evaluated by Dual Energy X-ray Absorptiometry (DXA).

RESULTS: The estimated correlation coefficients values were as follows: total BMD depending on segmental BMD of arms, legs were fitted with correlation coefficient of (r=0.92) and (r=0.91) respectively; also it were fitted with (r=0.85), (r=0.84), (r=0.73), (r=0.70), and (r=0.65) for head, pelvis, ribs, thoracic spine and lumber spine respectively; p<0.0001.

CONCLUSION: The mean total bone mineral density BMD of the total body for both genders shows highly significant; (p-value = 0.0001) through the ages (20-29). The same results are shown in the ages of (60-69) years with a significant relationship between males and females; (p=0.01). All the other groups (10-19), (30-39), (40-49), (50-59) and (70-80) years showed no significant relationship between both genders, where all mean total BMD amounts were small in female subgroups; p>0.01.
