Published: January 2021

Waste water from the textile industry is one of the major sources of contamination causing serious health problems. In textile waste water, dyes are the main pollutant. In this research work textile waste water was treated with various organic acid-activated clays to remove the dyes. Pink Azo dye was selected as a component to remove from waste water. Adsorbent selected was bentonite clay and was activated by acids such as phosphoric, acetic, oxalic, and citric acids. Adsorbent characteristics have been analyzed through infrared spectroscopy (FTIR) and Scanning Electron Microscope (SEM) while the removal of dye at various temperatures has been analyzed through Ultraviolet (UV) analysis. It was observed that the bentonite clay-treated with phosphoric acid had relatively maximum capacity to remove the dye while the clay treated with oxalic acid got minimum capacity to remove the dye from same waste water.

Published: January 2021

The nuclear structure of  40Ar, 112Cd, 133Cs, 151Eu, 154Sm, and 226Ra target nuclei used in nuclear battery technology was investigated. These nuclei are widely used for the radioisotope thermo-electric generator space studies and for betavoltaic battery microelectronic systems. For this purpose, some nuclear static properties were calculated. In particular, the single particle radial nuclear density distribution, the corresponding root mean square radii, neutron skin thicknesses, and binding energies were calculated within the framework of Hartree-Fock approximation with Skyrme interaction. The bremsstrahlung spectra produced by the absorption of beta particles through the betavoltaic process and backscattered photons spectrum were also studied. All the obtained results were compared with available experimental data.

Authors: Abdullah Najlaa J. , Essa Abbas F. , Hasan Salma M.
Published: January 2021

Polyaniline (PANI) polymer was successfully prepared by the chemical oxidation method at 0 oC. Polyaniline-nano grapheme (GN) powder nanocomposites were prepared by the addition of GN with different weight ratios (0.1, 1, 5, and 10 g wt. %) during the polymerization of PANI. It was found that the polymerization reaction of poly-aniline was exothermic.  The effect of adding nano-graphene powder during polymerization process on the time and temperature of the reaction was studied. The resulting polymer was diagnosed using several methods, including Fourier transform infrared spectroscopy (FT-IR) and UV-VIS spectrophotometry. The results of FTIR demonstrated a shift to higher wave numbers in the peaks of nanocomposites, due to PANI peaks, in addition to the matching between the groups of active sites of the polymer with its chemical composition. The results of the optical properties showed a decrease in the energy gap of the nanocomposite compared with that of the pure PANI sample. The morphology of the samples was studied using Scanning Electron Microscope (SEM). The increase in the concentration of GN led to a change in the surface morphology of the composites. The results predict that the PANI/GN nano-composites can be used in many applications, such as those of sensors.
Improving the Iraqi Oil Well Cement Properties Using Barolift: an Experimental Investigation
Authors: Hadi Ali M. , Al-Haleem Ayad A.
Published: January 2021

Cement is a major component in oil and gas drilling operations that is used to maintain the integrity of boreholes by preventing the movement of formation fluids through the annular space and outside the casing. In 2019, Iraq National Oil Company ordered all international oil and gas companies which are working in Iraq to use Iraqi cement (made in Iraq) in all Iraqi oil fields; however, the X-ray fluorescence (XRF) and compressive strength results in this study show that this cement is not matching with American Petroleum Institute (API) standards.

During this study, barolift was used to improve the properties of Iraqi cement used in oil wells at high pressure and high temperature (HPHT). Barolift (1 g) was added to cement admixture to evaluate its influence on improving the performance of cement, mainly related to the property of toughness. 

Primarily, the quality and quantity of cement contents were determined using X-ray fluorescence. Experiments were conducted to examine the characteristics of the base cement and the cement system containing 1g of barolift, such as thickening time, free water, compressive strength, and porosity. X-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X-ray spectroscopy (EDS) were conducted for analyzing the microstructure of cement powder.

The experimental results showed that barolift acted as a retarder and improved the thickening time, slightly increased the free water, enhanced the mechanical properties, reduced the porosity, and aided in scheming new cement slurry to withstand the HPHT conditions. Microstructure analysis showed that barolift particles blocked the capillaries by filling cement spaces and, thus, a denser and stricter cement network was achieved.

Authors: Mahmood Mohammed J. , Alwan Alwan M.
Published: January 2021

This work is related to the investigation of the effects of porous silicon (PSi) morphologies on the performance of plasmonic gold nanoparticles (Au-NPs) hot spot SERS sensors for the detection of amoxicillin molecules. Two Si wafers with different resistivity values of 10 and 100 â„¦.cm were used to synthesize a PSi layer of pores- and mud-like structures, respectively, by pulsed photo chemical etching process. The hot spot SERS sensors were synthesized by incorporating the Au-NPs within the PSi morphologies of pores- and mud- like structures which are characterized by high density of nucleation sites. Plasmonic Au- NPs with different sizes and hot spot regions were incorporated into the porous structures by the ion reduction process. It was recognized that the PSi morphologies have a considerable influence on the fabrication process of the detection sensors and, consequently, on the detection process. The plasmonic Au-NPs hot spot SERS sensor based on the PSi morphology of the mud-like structures shows higher sensitivity than that of pores-like structures, even at very low concentrations of amoxicillin solutions.
Representative Sector Modeling and Waterflooding Performance in Rumaila Oilfield
Authors: Shamkhi Mustafa Kamil , Aljawad Mohammed Salih
Published: January 2021

Rumaila supergiant oilfield, located in Southern Iraq has a huge footprint and is considered as the second largest oilfield in the world. It contains many productive reservoirs, some known but without produced zones, and significant exploration potential. A fault divides the field into two domes to the north and south. Mishrif reservoir is the main producing reservoir in the North Rumaila oilfield. It has been producing for more than 40 years and is under depletion. However, it was subjected to water injection processes in 2015, which assisted in recovery and pressure support. Thus, requirements of managing flooding strategies and water-cut limitations are necessary in the next stages of the field life.

     In this paper, sector modeling was applied to a specific portion of the field, rather than full-field modeling, to accelerate history matching strategy and correlate static to dynamic modelsâ€™ efficiently, with a minimum level of tolerance. The sector was modeled by surrounding with additional grid blocks and two pseudo wells to achieve a good matching with actual available data.

     PVT data were used for fluid modeling of a well contained in the sector, and two rock functions were inserted to the model to achieve acceptable history matching. Twelve wells were considered in this research, two of them were injectors and the remaining are producers. For future performance, some of these wells were subjected to new completion and workover processes for field development and pressure maintenance. The importance of the development plan is to represent a way for field development without new wells to be drilled. This was conducted by adding perforations to some wells, plugging the high water-cut production zones, changing production and injection rates, and converting the producers to injectors.

Authors: Akram Ghufran TH. , Kandala Nuha J.
Published: January 2021

Miscarriage is one of the fundamental complications occurring in pregnant women. Many fastidious and uncultivated bacterial species are related to miscarriage and have a significant role in the infection. The association between inverse pregnancy outcomes and infections of abnormal bacteria has been rarely investigated. Therefore, this study aimed to determine Leptotrichia amnionii and Atopobium vaginae as a risk factor for miscarriage states. A total of 80 cervical swabs and blood samples were obtained from females (34 non-pregnant with recurrent spontaneous miscarriage, 11 pregnant who had previous miscarriage, and 35 without miscarriage as control) who were referred to a hospital in Baghdad city. The relationship between demographic characteristics and miscarriage groups indicates a positive association between the age of 30 years and >45 years and miscarriage states, while no significant association (p>0.05) was found for the other parameters compared with the control. Also, no association was observed between the levels of TORCH IgM , antiphospholipid (APL) IgM, and anticardiolipidin (ACL) IgM antibodies and spontaneous miscarriage. The findings of RT-PCR detection revealed that, out of 45 samples of recurrent spontaneous miscarriage, 17 were detected with high-risk of L. aminonia compared with two samples from the control group. Also, 7 samples of recurrent spontaneous miscarriage were shown to be infected with A. vaginae compared with five samples from the control group. The adjusted odd ratios (ORs) of L. anmionii for spontaneous miscarriage and pregnancy states were 7.89 (CI 95%, 1.60 - 39.00) and 9.43 (CI 95%, 1.43 - 61.9), respectively, with highly significant difference between the study groups compared with the control. While no significant result was recorded between the adjusted ORs of A. vaginae for spontaneous miscarriage and pregnancy states, which  were 1.23 (CI 95%, 0.416 - 3.67) and 0.636 (CI 95%, 0.083 - 4.88), respectively, compared with the control.

Human Herpes Virus-8 (HHV-8) is a sexually transmitted viral infection that can infect the prostate epithelium in immunocompromised adults. Recently, HHV-8 was related to the development and progression of several human malignancies like prostatic adenocarcinoma. This retrospective research was designed to analyze the distribution and possible impact of HHV-8 infection on prostatic adenocarcinogenesis. A total number of one hundred formalin-fixed prostatic tissues were enrolled in this research; forty Prostate Adenocarcinoma (PAC) biopsies, forty biopsies from Benign Prostatic Hyperplasia (BPH), and twenty Apparently Normal Prostatic Tissues (ANPT) as a control group. Detection of HHV -8 DNA was achieved by a highly-sensitive variant of Chromogenic In Situ Hybridization (CISH) technique. In the mean age of PAC patients was 64.08Â±7.54years. Detection of CISH reactions for HHV 8- DNA was observed in tissues of 70% (28 out of 40) of PAC patients and 30% (12 out of 40) of BPH tissues, whereas no positive reactions were detected in the ANPT group. Detection of CISH reactions for HHV 8- DNA was observed in 55.6%  of tissues of PAC patients  with well grade histopathological examination,  87.5% of moderate grade, and 69.6% of poorly differentiated grade. It can be concluded that HHV-8 infection might contribute in prostate oncogenesis, together with other essential oncogenic viruses.
Why Indonesia Maintain Capital Punishment?
Authors: Fardiansyah Ahmad Irzal
Published: January 2021

The death penalty in Indonesia is still maintained to combat crime within the Indonesian criminal law reform. Although many states have it removed, Indonesia would have the sole discretion to keep it. Despite the opposition, the death penalty application still has a juridical and sociological basis, so it is still legal to be maintained. Indonesia itself has overshadowed the death penalty with a form of legality according to international law so that the position of Indonesia that still maintain the death penalty cannot be blamed. Moreover, sociologically, Indonesian people still accept those who commit an offence who may have profound implications that could lead to the death penalty. This issue is what became the basis for lawmakers in Indonesia to keep it. This research uses the doctrinal method toexamine various regulations regarding capital punishment and non-doctrinal to understand the community's situation related to the existence of capital punishment in Indonesia. The death penalty is a more effective deterrent and therefore prevents crime better. With the death penalty, others were about to commit a similar crime is expected not to commit the crime. The death penalty is more effectively immobilizing offenders. Perpetrators, in principle, still manage to have the desire to commit the crime again after release. The death penalty for perpetrators of crimes is not a violation of human rights, but rather to respect human rights itself, namely for victims of crime. The setting and the application of the death penalty in Indonesia until now is still needed. They are considering that there are still many crimes that undermine humanity's values or the crimes that harm the State and crackdown on corruption in society.

Authors: Hofmann A. , Anhaeusser C.R. , Li X-H.
Published: January 2021

Layered ultramafic–mafic complexes are a common component of the stratigraphically uppermost part of the Onverwacht Group of the Barberton Greenstone Belt. Associated with the Mendon Formation in the south and the Weltevreden Formation in the north, they represent an assemblage of thick differentiated flows and shallow synvolcanic intrusions ranging in composition from dunite to gabbro. U-Pb zircon dating of gabbro from the Sawmill and the Mundt’s Concession ultramafic complexes from the northern part of the Barberton Greenstone Belt yielded ages of 3 258 ± 8 Ma and 3 244 ± 11 Ma, respectively. The ultramafic complexes are thus regarded to have been emplaced during a magmatic flare-up in the final stage of Weltevreden Formation volcanism, post-dating ultramafic magmatism in the southern part of the belt by several millions of years and thus suggesting diachronous evolution of the Onverwacht Group in the Barberton Greenstone Belt.

The structures of new compounds were elucidated by the analysis of HRESIMS and NMR spectroscopic data, and the absolute configurations were determined by modified Mosher’s method, ECD calculation and single-crystal X-ray diffraction. Cytotoxicity and antibacterial activities of 1 were assayed and regrettably 1 didn’t display any cytotoxicity and antibacterial activity. 3 was the first phomopsiketone derivative obtaining the lactone.

A chemical investigation was carried out on a crinoid Colobometra perspinosa collected from Hengchun Peninsula in the South China Sea, which led to the isolation of five angular naphthopyrones (1–5), including one new metabolite, 8-hydroxy-5,6,10-trimethoxy-2-pentyl-4H-naphtho[1,2-b]pyran-4-one (1). Their structures were assigned based on spectroscopic methods, including UV, HRESIMS, 1D- and 2D-NMR spectra. The anti-inflammatory activity of the isolated compounds was evaluated and compound 5 was found to inhibit the accumulation of the pro-inflammatory iNOS protein in LPS-stimulated RAW264.7 macrophages.
Phytochemistry, Pharmacological Potency, and Potential Toxicity of Myoporum spp.
Authors: Musa Arafa
Published: January 2021

Genus Myoporum family Myoporaceae, includes approximately 32 species of woody small trees or shrubs, most of them are native to Australia and surrounding territories. Only certain species have been thoroughly studied and rich in flavonoids, phenylethanoids, Phenylpropanoids, terpenoids, iridoids, essential oil, and trace alkaloids. The essential oils are characterized by sesquiterpenes type components, either in ketone or alcoholic forms usually combined to a furanoid moiety. Myoporum spp. have been utilized in folk medicine for treatment of various diseases and were used as antidermatitis, antibacterial, antipyretic, anti-pulpitis, antipsychotic, anti-inﬂammatory, detoxicant, and others. Despite all these benefits, Myoporum spp. must be cautiously employed due to their potential toxicities, which arise from the presence of furanosesquiterpenoid contents, particularly in their essential oil. The toxicity influences liver and can extend to kidney and lung causing injury. The present review aims to explore the phytochemistry, beneficial uses and the toxic potentials of Myoporum spp.

Clinopodium sericeum is widely used in Peruvian folk medicine in the form of infusion to treat stomach distress, indigestion and antiflu. In this study, the essential oil from C. sericeum was obtained by hydrodistillation, analyzed by GC and GC/MS, and 73 compounds were identified. Major components of the oil were b-germacrene-D (15%), b-caryophyllene (13.8%), and sabinene (11.2%). Furthermore, we assessed the in vitro biological activities displayed by the oil obtained from the aerial parts of C. sericeum, namely the antioxidant, antimicrobial and antiproliferative activities. The antioxidant activities of the essential oil were evaluated by FRAP, CUPRAC, ABTS and DPPH radical scavenging activity. The essential oil displays antibacterial activity against Gram-negative and Gram-positive bacterial strains (MIC 50-200 µg/mL) in a dose-range close to standard antibiotics. Such activity may be related to the presence of terpene compounds. The antiproliferative activity of the essential oil was measured in vitro using the MTT colorimetric assay in healthy non-tumorigenic cells (HEK-293) and in three human cancer cell lines (T24, DU-145, and MCF-7). The calculated IC50 values were around 0.2 mg/mL. Since the essential oil was almost devoid of antioxidant activity, its anti-proliferative action is unlikely related to oxidative stress and relies on other unknown mechanisms.

The programme for combatting venereal diseases in the Soviet Occupation Zone of Germany (SOZ), the German Democratic Republic (GDR) and the Polish Peoples’ Republic (PPR) after the Second World War was adopted from the Soviet healthcare model. In order to maintain the spread of infections, both countries introduced specific legislation. The analysis of the regulations shows several similarities, such as establishment of easy access to anti-venereal health services, interruption of the chain of infection, and special treatment of individuals who constituted a danger of spreading the infection through compulsory hospitalisation. However, some differences are also visible. In the PPR, the decision about compulsory hospitalisation was left to individual evaluation of the attending physician. Closed venereology facilities or reformatories for treatment of venereal diseases, which existed in the GDR, were not established through legal regulations in the PPR. Since 1964, Polish law specifically targeted prostitutes and alcoholics as sources of spreading venereal diseases. These groups were not mentioned in the German legal acts. Analysis of praxis of compulsory commitment in the SOZ and GDR shows that mostly young women characterized as “drifters” were sent to closed venereology wards with breach of legal regulations. The number of prostitutes constituted only a very small fraction. In the PPR, the data from contemporary literature also indicates a considerable number of young women, the so-called “drifters”, committed to venereology ward.

The publication of articles by F. Steger, M. Schohow, M. Orzechowski 1 and I. Lipša 2 in the last two issues of the journal on the control of venereal diseases in the GDR, the Polish People Republic (PPR) and the Latvian SSR made it possible to expand joint academic interdisciplinary (historical, medical and socio-anthropological) research on this topic in four universities in Germany, Latvia, Lithuania and Estonia.

Objective

To determine the proportions of patients who (1) perceived their symptoms to be satisfactory, (2) perceived their treatment to have failed, or (3) perceived that they improved to an important degree at 3 months after arthroscopic meniscal surgery; and to determine Knee injury and Osteoarthritis Outcome Score (KOOS) subscale scores corresponding to the Patient Acceptable Symptom State (PASS), treatment failure, and the minimal important change (MIC) for improvement.

Design

Prospective cohort study.

Methods

Patients from the Knee Arthroscopy Cohort Southern Denmark who had arthroscopic meniscal surgery were included. The PASS, treatment failure, and MIC improvement values were calculated for the KOOS subscales with anchor-based approaches, using the adjusted predictive modeling method. Subgroup analyses were performed by stratifying by age (40 years or younger versus older than 40 years) and surgery type.

Results

Six hundred fourteen patients (44% female; mean ± SD age, 50 ± 13 years) were included. At 3 months after arthroscopic meniscal surgery, 45% of patients perceived their symptoms to be satisfactory, 19% perceived the treatment to have failed, and 44% to 60% perceived that they had improved to an important degree across the 5 KOOS subscales (for PASS/treatment failure, respectively: pain, 74 and 60 points; symptoms, 72 and 61 points; function in activities of daily living, 81 and 68 points; sport and recreational function, 43 and 26 points; and knee-related quality of life, 52 and 40 points; for MIC improvement: pain, 12 points; symptoms, 8 points; function in activities of daily living, 12 points; sport and recreational function, 17 points; and knee-related quality of life, 9 points). The PASS values were 6 to 17 points higher for patients 40 years or younger compared to patients older than 40 years.

Conclusion

At 3 months after meniscal surgery, approximately half of the patients perceived their symptoms to have improved to an important degree, 4 in every 10 patients perceived their symptoms to be satisfactory, and 2 in every 10 patients perceived the treatment to have failed.

There are presented data of the primary screening of bacterial strains antagonists from a collection of the biological methods lab of the V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK) to an aggressive isolate of the Phoma rot pathogen (Phoma macdonaldii Boerema) affecting sunflower by a method of double or crops. We estimated 27 bacterial strains of Bacillus genus on the three nutrient mediums (potato-sucrose agar (PSA), Taylon-3 and oat agar (OA). We stated 21 of them possessing antagonistic activity with a type of action mode against Phoma pathogen on sunflower named antibiosis. We determined for three strains presence of a competition for nutrient area without formation of a sterile zone with pathogen. Maximal sterile zone to Phoma rot pathogen was formed by strains: 11-3 Bacillus sp. (21.0 mm) on PSA; B-4 B. circulans (19.0 mm) on a Taylon-3 medium and D 1-1 Bacillus sp. (17.0 mm) on OA. Eight from the nine collection bacterial strains of Pseudomonas genus demonstrated antagonistic activity to Phoma rot on PSA and King’s B, and seven strains – on OA with one type of action mode – antibiosis. Maximal sterile zone to Phoma rot pathogen was formed by strains: Oif 2-1 Pseudomonas sp., 16-2 Pseudomonas sp. and 12-2 Pseudomonas sp. (12.5– 12.0 mm) – on PSA; 16-2 Pseudomonas sp. (16.5 mm) – on King’s B; Oif 2-1 Pseudomonas sp. (18.0 mm) – on ОА.
