Authors: Ismael Dalaram S. , Vollmannová Alena , Musilová Janette , Timoracká Mária 
Published: February 2022

The aim was to evaluate the influence of the grown locality on risky metal intake from the soil to the chickpea seeds. The research was realised in three different localities of Iraq (Harer, Erbil, Ankawa) using the same chicpea cultivar. In all soil samples the determined total content of Co, Ni, Cr, and Cd exceeded the limit values (by 45% - 87%, 196% - 302%, 57% - 132% and 500% - 810%, respectively). In one locality (Harer) also the Cu content by 2% exceeded maximal allowed value given by the legislative. In all sample sites also the maximal available soil content of mobile Pb forms was by 5% - 265% exceeded. Despite of extremely high soil contents of Co, Ni, and Cr the investigated chickpea seeds are from the point of these risky metal contamination safe. All determined values of heavy metal contents are lower than hygienic limits. Only Cd and Pb amounts in seeds of chickpea from Iraq exceeded the limit value given by legislative. Based on our results we could suppose that chickpea can be risky food if it is grown in the soil with enhanced amounts of Pb and Cd.

Published: February 2022

Internal corrosion of carbon steel pipes of oil and gas Companies in the Niger Delta area of Nigeria using coupons and ER probes is presented. Corrosion mechanisms for the lines vary with the fluid type and operational parameters. Aqueous corrosion with, in some cases CO2 corrosion additive, erosion corrosion and elevated temperature oxidation are corrosion mechanisms implicated in the pipes. No H2S-induced corrosion was observed for all the lines investigated. They act separately or synergistically to exacerbate the corrosion attack. Application of inhibitors of the amine group drastically lowered the corrosion rates. Effective inhibition regime had in an instance markedly lowered the corrosion rate of a line from 42.7080mpy to 1.3447mpy. The ER probes incorporation offered a comparative corrosion monitoring alternative and provided insight into the real time conditions of the lines over prolonged periods of times. The exercise proved very useful in determining the corrosion status of the pipes and helped to determine the lines that should require immediate maintenance intervention to obviate possible ugly incidents of breakouts and ruptures.

Ni-Cu-Zn ferrites are well-known technological magnetic materials used for manufacturing of multilayer chip inductor and applications in various electrical devices. The work is focused on the persuade of substitutions and sintering additive B2O3 on structural, transport and electromagnetic properties of Ni-Cu-Zn ferrites. The composition Ni0.28Cu0.10Zn0.62Fe2O4 + x wt. % where x= 0.2 to 0.8 for V2O5 was prepared by using the solid state reaction technique sintered at 1200oC with 6 hours holding time. Lattice parameters of Ni0.28Cu0.10Zn0.62Fe2O4 + x wt. % Bi2O3 are slightly decrease with increase x content. The grain growth by increasing the additives Bi2O3 content inter diffusion as results after > 0.4wt. % Bi2O3 content abnormal grain growth. Curie temperature (Tc) decreases continuously with increase of doped Bi2O3 additives in ferrite samples. The magnetization process all the samples are soft magnetic behavior of magnetic materials. Initial permeability (µi) decreases with increasing doped Bi2O3 content in ferrite samples and hence the highest value of quality factor is found for x = 0.4 within the range 20 kHz to 2MHz. The µi shows the flat profile from 1 kHz to 4MHz indicating frequency stability for all the ferrite samples. The visible grain growth indicates the improved electromagnetic properties. DC resistivity decreases with increasing temperature shows the semiconducting nature of the sample. With increasing the frequency, the dielectric constant is found to decrease continuously and remain almost frequency independent at higher frequency range.

Published: February 2022

Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones (coarse aggregate). However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials. While there is significant research on many different materials for aggregate substitutes such as granulated coal ash, blast furnace slag or various solid wastes including fiberglass waste materials, granulated plastics, paper and wood products or wastes, sintered sludge pellets and others. Recycled waste glasses were used as coarse and fine aggregates replacement in concrete. Coarse aggregates were replaced with Green Bottles coarse aggregates at third, half, two thirds, and 100% replacement ratios. The replacement of a third coarse aggregate was established as being the most suitable for retaining the properties of the concrete mix design. As for fine aggregates, in order to account for the numbers of variables and clearly establish a bench mark, the sand grading, color of glass, source of waste glass (bottles and non-bottles), and design mix strength were used as parameters. Fine aggregates from green, brown, and transparent bottles in addition to clear window waste glass were used. Concrete properties were tested in fresh and hardened states. The incorporation of glass sand regardless of the ratios of replacement showed no significant influence on fresh or mechanical properties of concrete except for the case of transparent bottles. Transparent bottles due to the wide source of obtainability have introduced a non-uniform factor that caused discrepancy compared to the rest of the group.

Published: February 2022

A novel 65nm Dynamic Random access memory (DRAM) cell, namely capacitor less RectFET based DRAM cell (CLRDC) is explored in silicon-on-insulator (SoI) wafer for embedded-DRAM (eDRAM) for system-on-chip (SoC), applications with Rectangular FET (RectFET) as its pass-transistor (PT). This CLRDC exploits its parasitic surround buried oxide capacitance (SBC) of SoI-wafer around RectFET (source) for realizing its ‘charge storage capacitance (Cs). For Cs=30fF (femtoFarad) target, it’s found to need an area factor of 4.3µm2 with 5nm thick SoI buried-oxide. This SoI wafer is explored to yield a capacitance density Cbuox=6.91 fF/µm2. The DC parameters of the PT are found to be very sensitive to process anneal temperature (Ta) and so are its DC characteristics too. A 2% increase in the Ta from a nominal 1000oC has resulted in an increase of 30% and 1.1% in the RectFET’s leakage (Idsat-off=I-off) and on-state (Idsat-on=I-on) currents respectively. The CLRDC cell transfer ratio T is also found to be a function of small signal frequency (f), Ta, and source/drain bias voltages Vs/Vd, respectively. And finally the retention characteristics of this CLRDC is again found to be a function of I-off and I-on currents of RectFET, when studied at RectFET’s (drain) supply voltage VDD=1.2V.

Published: February 2022

Ground penetrating radar (GPR) is a very effective tool for detecting and identifying objects below the ground surface. based on the propagation and reflection of high-frequency electromagnetic waves. The GPR reflection can be affected by many things like the type of objects orientation, their shapes ..ect. The purpose of this paper is to study by simulation the effect of objects orientation in two different mediums (dry and wet sand) on the GPR signal reflection using Reflexw software which is based on a numerical method known as finite difference in time domain (FDTD). The simulations that have been realized included a conductor and dielectric objects. The results obtained have led us to find that the propagation path, the reflection strength and the signal form change with the change of object orientation and nature. To confirm the validity of the results, we compared them with experimental results previously published by researchers under the same conditions.

Published: February 2022

Blends composed of styrene butadiene rubber (SBR) and acrylonitrile-butadiene rubber (NBR) were fabricated by melt blending technique using two-roll mill blend machine. Cis- polybutadiene rubber (CBR) was used as a compatibilizer for enhancing the homogeneity between SBR and NBR phases in blends. Although, no previous reports were found to discuss improving electrical properties of vulcanized SBR/NBR blends using unfilled rubber system (i.e. no fillers incorporated). Raman spectra and SEM images indicate that a significant compatibility within the rubber matrix is observed, due to using CBR compatibilizer. The effect of SBR/NBR blend ratio on curing characteristics, physico-mechanical properties, and physicochemical properties (e.g. network characteristics and thermodynamic parameters) were studied. SBR/NBR blend showed comparatively better mechanical properties, compared to each other individually rubber system. Curing parameters e.g. Mooney viscosity and hardness were increased, while a reduction in cure time and specific gravity was observed with increasing SBR ratio in blends. Results revealed that increasing SBR resulted in an enhancement of the tensile strength, modulus at 300 % and elongation at break up to 40 phr, and then gradually decreased. The TGA results indicated that SBR/NBR blends were thermally decomposed at a temperature range of 340-520°C. The notable decrease of DC conductivity (?dc) of vulcanized blends is owing to the decrease of NBR, which is a polar portion and is responsible for increasing the conductivity of vulcanized blends. This proved that the targeted industrial applications for vulcanized blends are entirely depending upon SBR/NBR blend in elastomers matrix.

A Comprehensive Review of the Diagnostic and Treatment Methods for Ovarian Cancer
Authors: Davis Michelle 
Published: February 2022

Ovarian cancer is amongst the most life-threatening malignancy of the female reproductive system, whereas 90% of those ovarian cancers are epithelial with an overall poor five-year survival rate of 44% across all stages and all races [1]–[2], [31]. This paper aims to review the current treatment and diagnostic strategies for ovarian cancer [3]. Using grounded substantial research, multiple figures were developed to show the relations of ovarian cancer diagnostics and ovarian cancer therapeutics. It is a great start to look into what may be causing most patients to become resistant to the current standard of care, platinum-based chemotherapeutics, for ovarian cancer [4]. A comprehensive literature review will be used to understand the genetic basis of the disease and possible cancer growth patterns, so we could possibly introduce better diagnostics and therapeutics [5]. The findings show that there are a variety of treatments options other than the standard of care, platinum-based therapy [6]. Nanoparticle encapsulation therapy is one way that has been approved by the FDA to therapeutically treat ovarian cancer without the platinum resistant side effects [7]. Also, the discovery of different diagnostics for ovarian cancer can help with better individualized treatments for patients with different forms of ovarian cancer [8]. Currently, the only serous diagnostic test for the detection of ovarian cancer is high levels of Cancer Antigen 125 (CA-125), which is only shown in 50% of early staged ovarian cancers [16]. The main treatment option for ovarian cancer is platinum-based drugs, in which most cases of patients with ovarian cancer will become resistant. Detecting and treating ovarian cancer while the cells are small, contained, and still in the early stages in vivo still remains to be a challenge [9]. Here, we will demonstrate the bioelectrical interactions of the ovarian cancer cells fused with the magnetic iron oxide nanoparticles with the use of an MRI. The findings demonstrate that the diagnostic method for the early detection of epithelial ovarian cancer requires the use of magnetic iron oxide nanoparticles with specific ligand external profiles as a contrast reagent to make the small-sized ovarian cancer cells appear more visible under MRI.
