Maternal Iron Deficiency and Its Effects on the Fetus and Infant
Authors: Lumbanraja Novita , Ikhssani Agung
Published: May 2023

Iron is essential for the function of all cells through its role in oxygen delivery, electron transport, and enzymatic activity. Cells with high metabolic rates require more iron and are at greater risk for dysfunction during iron deficiency. Iron deficiency is associated with adverse pregnancy outcomes, including increased maternal disease, low birth weight, prematurity, and intrauterine growth restriction. The rapidly developing fetal brain is particularly at risk for iron deficiency, which can occur due to maternal iron deficiency, hypertension, smoking, or glucose intolerance. Low maternal gestational iron intake is associated with autism, schizophrenia, and abnormal brain structures in the offspring. Newborns with iron deficiency have impaired recognition memory, slower processing speed, and poorer bonds that persist despite postnatal iron deficiency. Scientific sources were obtained from Google Scholar and Pubmed in the form of textbooks and scientific journals totaling 33 pieces. This literature review describes the neurocognitive and mental health consequences of fetal iron deficiency and emphasizes that fetal iron is a key nutrient influencing brain development and function throughout life

The Role of Vitamin C in the Prevention of Premature Rupture of Membranes
Authors: Azqinar Tiara Cornela , Ikhssani Agung
Published: May 2023

Premature rupture of membranes [PROM] is an early event in approximately one third of preterm births resulting in significant infant mortality and morbidity. The exact mechanism by which the fetal membranes weaken and rupture in term and preterm pregnancy is unknown. However, it has been hypothesized that the fetal membranes weaken and eventually rupture as a result of collagen remodeling and apoptosis. Some studies have speculated that vitamin C supplementation during pregnancy will be useful in the prevention of PROM but some studies have also shown that vitamin C supplementation does not affect normal fetal membrane remodeling processes leading to weakening and rupture of the fetal membranes. This literature review discusses the role of Vitamin C in the prevention of PROM, where the role of vitamin C can induce collagen degradation and apoptosis. The assumption that vitamin C supplementation may be a prophylactic regimen for premature PROM should be investigated further. Caution should be exercised in using vitamin C supplements to prevent PROM in pregnant women. This literature review discusses the role of vitamin C in preventing premature rupture of membranes.

Published: May 2023

Gypsum is a common interior construction material, especially when used as a finishing element. However, interest in prospective uses of gypsum as a finishing component has diminished in recent years as a result of its weak mechanical strength and brittle character, which is essential in interior construction. Therefore, to overcome this challenge, the effect of pineapple leaf fiber on gypsum was investigated. Five different composite configurations of 2%, 3%, 5%, 10%, and 20% pineapple leaf fibre (PALF) with two PALF sizes of 5 mm and 15 mm were prepared and tested after 7 and 28 days of curing. The results of the tests show that materials reinforced with 2% PALF have significantly improved mechanical properties. The compressive strength of a gypsum composite increased by 12.4% when 2% PALF was added. Flexural strength increased by 59% when 2% PALF was added to the mixture. The study provided a means of making gypsum composites having greater mechanical strength than those made from fossil oil-based polymers. It also found relevant use of pineapple leaf, an agricultural waste.

The interest in prospective uses of gypsum as a finishing component has diminished in recent years as a result of its weak mechanical strength, which is essential in interior construction. Therefore, to overcome this challenge, researchers have come up with various ways of improving the gypsum composite materials. The microstructure of the composites and the contact surface with pineapple leaf fibre were investigated by Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD). The microstructural properties of the gypsum paste changed when pineapple leaf fibre was added. These studies showed that at 2% fibre volume, a jellylike surface coating was formed around the gypsum crystals, giving the pineapple leaf fibre (PALF)-gypsum composite its high interlocking and compactness, thereby impacting high strength than the pure gypsum and this suggests its broader application in building industry for production of partition boards

A comparative study was carried out to evaluate the fatty acid profile and physicochemical qualities of oil extracted from the unfermented and fermented seeds of Annona squamosa. A. squamosa powdered, fermented and unfermented seeds were extracted using soxhlet extraction. The fatty acid composition was identified using GC-MS. The physiochemical properties were determined using standard analytical methods. Unfermented oil had a total saturated fatty acid (TSFA) of 37.41%, of which palmitic acid was the most predominant. Total monounsaturated fatty acid (TMUFA) content of the fermented oil sample was 58.48% while total polyunsaturated fatty acid (TPUFA) content was 2.76%. Total amount of unsaturated fatty acids (TUFA) found in the fermented oil was greater than TSFA. The main MUFA identified was oleic acid, which ranged from 49.12 to 55.01% for both oils. The physicochemical properties showed that fermented oil had higher free fatty acid, iodine value and peroxide value of 3.810%, 108.508 mgl2/g and 0.830 mMol/kg respectively while unfermented oil had a higher saponification value of 180.112 mg KOH/g. The results indicated that the two oils from A. squamosa contained high amounts of PUFA and MUFA but the fermented oil showed higher TUFA than SFA, indicating suitability for consumption and industrial usage.

The soil samples were collected at irregular positions within the vicinity of the two auto repair shops at 0–20 cm and 20–40 cm depth. The samples were taken for examination of polychlorinated biphenyls (PCBs) and (Polycyclic aromatic hydrocarbons) PAHs. The samples were analysed in the lab according to regular technique, and 16 US EPA priority PAHs and PCBs were then examined using a gas chromatography-mass spectrometer (GC-MS). The potential toxicities were evaluated and values obtained were compared with United States permissible limits for soil quality. The total PAH values in the soil were between 0.17 μg/m3 to 4.97 μg/m3, with the soil samples near the truck maintenance shops having the greatest PAH concentrations between 0 – 20 cm below the surface. The most prevalent PAH species in soil samples was Fluoranthene, followed by Fluorene and Indeno [1,2,3-cd] pyrene. Also, PCBs were found in the location with 1,1′-Biphenyl, 2,2′,3,4,4′,5′-hexachloro- (PCB 138) having the highest concentration value followed by 1,1′-Biphenyl, 3,3′,4,4′-tetrachloro- (PCB 77). The findings of this study showed that both of these pollutants investigated are very prevalent in these areas. There is a grave environmental concern because the discovered levels of PCBs and PAHs exceed the permissible limits set by the USEPA standards.

The flow of fluids and heat characteristics through free convection within an enclosed space has gained substantial study due to the various applications in manufacturing industries. This work examined the influence of buoyancy factors on normal convection in a heated tube filled with Copper (Cu) nanofluid. The method of finite difference was employed to characterize the regulating fluid formulae, and C++ programming language was employed to evaluate the Navier Stoke and continuity fields. This study examined Cu nanoparticles with particle sizes ranging from 1% to 10% and buoyancy values between 2.6 x 103 and 2.8 x 103 N. Cu nanofluid was used as the working fluid and the findings are presented as temperature gradient, Nusselt number, stream function, and vorticity curves. The findings revealed that an increase in the weight proportions of nanoparticles to 0.04 amplifies the buoyancy parameters to the highest value of 2.75 x 103 N; it yields a substantial enhancement in the heat transport rate by convection. Also, as the buoyancy factor increases, the temperature gradient, vorticity, and stream function of the nanofluid improve, while the local drag coefficient decreases. This study advances the understanding of buoyancy-driven convective flow and heat behavior in the technical design of floating vessels for safety and effectiveness.

Published: May 2023

To date, there has been continued demand for more effective, less expensive, and accessible coating systems for durable corrosion and wear protection of auto auto-bodies, with a research need to meet the demands. The rationale behind this study was to create a high high-quality, low low-cost bituminous paint for use in protecting the under parts of automobile chassis against corrosion and wear, particularly in Nigeria. Five paint blends containing various proportions of 70 –100% Agbabu natural bitumen, 02 02–5% kerosene, 0 0–8.5% cobalt, 0 0–1% pigment, and 0 0–2.1% lead drier were produced and characterized by their basic physicochemical properties. The blends were brush brush-coated to a 1.78 1.78-mm average thickness on plate samples of mild steel, a commonly and widely applied but highly corrosion corrosion-susceptible chassis material type. Corrosion and wear tests performed on the steel samples under 1.78 1.78-mm -thick hard hard-dried coatings of the paint blends revealed that the blend with 75% bitumen, 15% kerosene, 8% cobalt, 0.6% pigment, and 1.4% lead drier content could perform exceptionally well in protecting the steel a t the coating thickness. X X-ray fluorescence and scanning electron microscopy analyses of that paint blend were conducted to understand its distinct chemical compositions and microstructural homogeneity level. The 1.78 1.78-mm -thick coating of that paint blend’s adhesion adequacy to the steel was also investigated. Analyses of the collected data revealed that the blend contained 25 different chemical species that are benign to steel corrosion, had a more or less uniform microstructure demonstrating its homogeneity, had minimal intergranular boundaries indicating minimal ingress of corrosion corrosion-causing agents to the steel underneath its coatings, and its hard hard-dried thin coatings would have excellent adhesion to any ferrous chassis material..

Mechanical properties of particulate granite and pulverized coconut shell hybrid reinforced epoxy composites were studied in this research, with the aim of converting agro-waste and natural occurring element to develop a new composite material for engineering applications. The stir cast method was used to produce the composites. The hybrid composites were developed by adding varying weight percentage of fine granite/coconut shell particles as reinforcement to epoxy matrix and the effect of the particles on the mechanical properties of the composite produced was investigated. The result revealed that the tensile strength ranges between 14.44 – 22.78 MPa, tensile modulus ranges between 300.52 – 718.47 MPa, flexural strength and flexural modulus varies between 43.03 – 77.19 MPa and 1009.35 – 1820.81 MPa, respectively; impact strength varies between 33 – 54 Joules and the hardness varies between 30.14 – 46.14 HRC. Finally, from the investigation, it is evident that the selection of percentage of filler content suitable for the polymer composite depends on the required properties for various engineering applications.

A robotic manipulator consists of a robotic arm and an end-effector. The function of the end-effector or robotic gripper is to allow the robotic arm to grasp and manipulate objects. The traditional hard robotic grippers are prone to poor gripping ability when grasping objects with irregular shape or in-ability to passively adjust force to delicate objects. Soft Robotic grippers were purposely designed to solve these disadvantages. In this work, a novel light weight robotic gripper based on grasping action of holding an object in between two strips of in-elastic flexible material under tensile force developed when pulled is hereby presented. Force analysis of the gripper was carried out as well as validation experiments. Analysis shows that the minimum pulling force to be exerted by the gripper on the grasping strips is directly proportional to the payload mass and the strips lengths. It is also inversely proportional to the coefficient of static friction between the payload-strips interface and the horizontal extent of the payload. Experimental results supported these observations. Moreover the predicted analytical values of gripper pulling force agreed reasonably with the empirically derived values. A proof of concept model of the gripper successfully grasps a 185g object.

The epidemic model of typhoid is considered to be a control strategy for the undeviating transference of infectious disease. Due to its high accuracy and efficiency in solving nonlinear differential equations, the homotopy perturbation method is coupled with the Riemann-Liouville fractional integral operator I of order n E (0,1) to obtain the approximate analytical solution of the epidemiology model presented at different level of n. The obtained results were subjected to simulation process where the effect of the causative bacterial in the medium was studied at various level of n . The entirety of the computational procedures was conducted utilizing Maple 18, and graphical representations and tabular data were exhibited to facilitate a lucid understanding of the simulation outcomes. These findings indicate that curtailing Salmonella contamination is of paramount importance for minimizing the hazard of sickness and infection. This can be achieved through the observance of meticulous hygiene, which includes consistent hand washing with soap and water, thorough cooking of food, and appropriate storage and handling of edibles.

Thermal properties and chemical performance of newly developed Thevetia peruviana oil-based (TPO) bio-composites with short sisal fibers reinforcement were studied in this research, with the aim of producing materials derived from renewable resources for engineering applications. Three sets of TPO composites (5C, 10C and 15C) reinforced with sisal fibers 5, 10 and 15 wt% respectively were produced by compression moulding method. Thermographic analyser (TGA) was used to determine the thermal behavior of the new composites and the results showed that the composites thermal stability behavior increase with fiber loading. 5% degradation temperature (T5) and 10% degradation temperature (T10) of the new composites increased from 300 to 312 0C and from 338 to 419 0C, respectively. The char value of 8.264 of the unreinforced resin reduced on the addition of 5 wt% of fiber while there were enhancements in the char values of composites reinforced with 10 wt% and 15 wt% fiber. The chemical resistance and water absorption tests showed that the percentage gain/loss of the composites in all the reagents are negligible, with composite 5C showing superior resistance in all the media. The results showed that the newly produced bio-composites is a potential material for storage vessels production.
