Opis:
This research investigates a thermo-mechanical strength of three geometrical shape designs of an internal combustion (IC) engine piston by a finite element analysis (FEA). FEA was performed using Solidworks software for modelling geometrical piston designs, and the models were imported into ANSYS software for thermo-mechanical fatigue simulation. The work focused on predicting high stress intensity and indicated the fatigue critical regions and life of the piston shape design. AL7075-T6 aluminium alloy was used as a piston material and thermo-mechanical fatigue simulation was conducted based on the experimental stress-number of cycles recorded data from literature. Analytical results showed the similarity of the critical failure positions to some real failures in the IC engine piston, and the shape design modification of the piston. Hence, this concept can be used to satisfy the IC engine design needs at low cost.

Opis:
The current research aimed to use non traditional methods to control some stored grain insects. The effects of 180 millitesla (mT) magnetic field (MF) for six different exposure periods (3 min, 30 min, 1 h, 12 h, 24 h and 48 h) on mortality (%) of two stored grain insects, Tribolium casteneum adults and Trogoderma granarium larvae, reduction in F1-progeny (%), seeds germination (%) and seed components (%) after 8 months storage period were studied under laboratory conditions. According to results, the mortality (%) of tested insects increased with increasing of MF time exposure. Trogoderma granarium was more resistant than T. casteneum in which mortality reached 56 and 75%, respectively 14 days after from exposure period. Without any negative effect on seeds germination (%) the MF was very effective in protecting stored wheat from insect infestation up to 8 months compared to non-magnetic seeds which became infested after 3 months of storage. Furthermore, the germination (%) was accelerated by 6 h compared to non-magnetic seeds. The MF level caused a slight increase in the percent of total carbohydrate, crude protein and ash while slightly decrease the percent of moisture, total fats and crude fiber.

Opis:
This paper aimed to investigate the effect of using ductile materials in the compression zone on the flexural performance of over-reinforced concrete beams. In order to avoid brittle compression failure, partial replacement of concrete with ductile materials layer in the compression zone was used. Four over-reinforced concrete beams of size 120 × 180 × 1,300 mm were cast and tested under three-point loading conditions. The steel fibers reinforced concrete (SFRC), slurry infiltrated fiber concrete (SIFCON), and ultra-high performance fiber reinforced concrete (UHPFRC) were used as ductile materials. The flexural capacity of the beams, failure modes, crack patterns, load-deflection relationships, ductility index, and toughness were investigated. The results showed that using ductile materials in the compression zone is an effective technique to increase the ultimate load, ductility, and toughness by up to 52.46, 84.78 and 279.93%, respectively, compared to the reference beam. In addition, the failure mode changed from brittle to ductile failure. Noting that the use of SFRC layer enhanced the ductility of over-reinforced concrete beams more than using UHPFRC and SIFCON layers. Also, one of the main advantages of this technique is led to increase the tensile reinforcement ratio up to 8.548% without needing the compressive reinforcement. Thus, ductile composite beams with a high flexural capacity were generated using an economical amount of ductile materials.

Opis:
Purpose: Human bone suffered some degeneration due to age and accidents; therefore, there are many interests in the prepared synthetic bone with properties nearer to natural bone. The present study prepared a nanocomposite of polypropylene reinforced with different weight fraction of Nano hydroxyapatite (HAp) to be used as a bone replacement with good biological properties that enhanced the growth of osteoplastic cells and enhance the prevention of clots and coagulates creation. Design/methodology/approach: Nanocomposite from polypropylene reinforced with different weight fraction of Hydroxyapatite (HAp) (1,2 and 3) % prepared by first dispersion Nano hydroxyapatite insolvent and then mixing with a pellet of polypropylene by the twin-screw extrusion process, the current research study the surface properties ( atomic force microscopy (AFM), contact angle test) Moreover, it studied the characteristics of prepared nanocomposite materials (Differential Scanning Calorimetry (DSC), Field Emission-Scanning Electron Microscopy (FE-SEM) and Fourier Transform Infrared (FTIR)). Findings: The AFM results show the surface roughness decreased with increasing content of HAp, which diminished the chance of creation clots and coagulates on it. The contact angle results referred to polypropylene behaviour transformed from hydrophobic to hydrophilic with addition HAp that permission to grow the osteoplastic cell on it, so the healing process is accelerated. Moreover, the FE-SEM images revealed uniform distribution and good bonding between polypropylene and Hydroxyapatite. The thermal properties were measured by the DSC test showed the melting temperature, and the enthalpy of melting (indicated to increase the crystalline structure per cent) are increased with increasing the percentage of Hydroxyapatite. Research limitations/implications: This research studied the characteristics of nanocomposite materials prepared by three steps (dispersion by ultrasonic device, manually mixed and melting and mixing by twin extruder) which can be used as a bone replacement. However, the main limitation was the uniform distribution of nano-hydroxyapatite within the matrix. In a further study, the cytotoxic test can be tested to study the effect of prepared nanocomposite on living cells’ growth. Practical implications: The interest object is how to connect among different properties to prepared bone replacement with good properties and biocompatibility that made able to stimulate the growth and healing process. Originality/value: The nano-hydroxyapatite is a biomaterial that has a composition similar to the natural mineral phase of the bone and does not have any negative effect, which enhanced the growth of osteoplastic cells and decreased the clots and coagulates creation; therefore, nano-hydroxyapatite is used to decrease the surface roughness which decreased the chance of coagulation creation and to enhance the hydrophilic properties.

Several mixtures, based on urea, urea hydrogen peroxide complex (UHP), triacetone triperoxide (TATP) with some inorganic oxidants were studied by means of ballistics mortar with TNT as a reference standard. The detonation pressure, P, detonation velocity, D, detonation heat, Q, and volume of gaseous product at standard temperature and pressure conditions (STP condition) were calculated by the mean of Explo5 V6.3. The relatively high explosive strength of some samples relative to the TNT charge, focuses on the positive influence of hydrogen peroxide presence in these mixtures, with advantage in the form of its complex with urea (i.e. as UHP). This influence connects with hydroxi-radical in the mixture under its initiation (as the first intermediate of this initiation reaction).

The quality of the water in Iraq’s Hilla River has been severely degraded as a result of human activities and industrial development. The QUAL2K model, a widely used one-dimensional water quality model, was used to simulate the river’s water quality parameter of CBODu and DO utilizing river and point-source flows rate as well as quality of water metrics observed along the river. Despite a severe lack of data in the research region, the QUAL2K model was determined to be an adequate instrument for the evaluation of quality of water. Simulated results of DO, BOD5, and temperature for the period (October 2022) showed the robustness of the model. Results showed that the two parameters (CBOD and DO) ranged between (9.5 and 10.65) mg/L and between (1.425 and 3.075) mg/L, respectively. Based on statistics, good agreement was found between the model predictions and field data. Thus, using QUAL2K model is an effective tool to manage the river water quality.

Opis:
Malignant Ovine Theileriosis (MOT) caused by Theileria lestoquardi is considered a major constraint for sheep production in many areas of the world including Sudan. Pulmonary oedema is thought to be the main cause of animal death, but the mechanism, the cell types involved and/or the probable cause of this pneumonia has yet to be defined. The present study was carried out to investigate the pulmonary involvement post T. lestoquardi infection and to identify the cell types involved in pneumonia. Apparently healthy sheep were exposed to ticks challenge in T. lestoquardi endemic area. Lungs impression smears and tissue sections for histopathology were processed. At necropsy, fifteen infected sheep revealed severe pneumonia associated with oedema and accumulation of creamygrayish frothy exudates. The microscopic findings of examined lungs showed emphysema, congestion, collapse and proliferation of immense amount of different kinds of cells. The current study indicates that T. lestoquardi infections are accompanied with remarkable pulmonary involvements and may lead to respiratory failure and death.

Opis:
The epidemiological aspects of sheep piroplasmosis in Sudan are poorly studied, and further investigations using sensitive and precise techniques are required. In this study, the Reverse Line Blot (RLB) hybridization assay was used to detect and simultaneously differentiate between Theileria and Babesia species. DNA was extracted from blood collected on filter paper (n=219) from apparently healthy sheep from six different geographical localities in Sudan. Results indicated that Theileria ovis (88.6%), T. separata (20.1%), T. lestoquardi (16.4%) and T. annulata (16.4%) DNA could be detected in the blood samples. Single and mixed Theileria infections were detected in 74 (33.8%) and 124 (56.6%) respectively and T. ovis being the most prevalent species in the country. T. ovis and T. separata were reported for the first time in sheep in Sudan.

Opis:
The mature Raudhatain and Sabriya fields have been in production for the last six decades. Each field consists of four main reservoirs that are vertically stacked over a depth of 12.000 ft and separated by shales. The field development strategy is, to drill several horizontal wells within the individual reservoirs to maximize production. Some of these horizontal and highly deviated wells, experienced severe drilling problems, such as stuck pipe and side-tracking. As reservoir pressure changes during the life of the field, the stress state is modified. Such changes have an impact on well completions and the behaviour of faults. Therefore, the combined effect of well trajectory and in-situ stress changes on wellbore stability, should be thoroughly investigated. Not only is it important to understand the natural geomechanical behaviour of the reservoir during production, but it is also important to know, how to harness that behaviour to enhance productivity. At the same time, it is essential that the geomechanics of the field are understood to avoid costly mistakes. Therefore, a 4D geomechanical model that integrates geology, petrophysics, laboratory testing, fluid flow and geomechanics to obtain a representative equilibrated stress state prior to and during production was constructed. The results can be used to compute 3D critical drilling mud weights that provide guidelines for the placement of new wells and necessary drilling mud weights along planned wells.
Złoża Raudhatain i Sabriya są eksploatowane od sześciu dekad. Każde z nich składa się z czterech głównych horyzontów odizolowanych warstwami łupkowymi w zakresie głębokości 12 000 stóp. Strategia rozwiercania tych złóż maksymalizująca wydobycie obejmuje kilkanaście odwiertów poziomych i silnie krzywionych w obrębie poszczególnych horyzontów. Wiercenia niektórych z tych odwiertów napotykają trudności w postaci zakleszczenia przewodów wiertniczych i niekontrolowanych odchyleń. Na skutek zmian ciśnienia złożowego występują istotne zmiany w rozkładzie naprężeń skały złożowej. Zmiany te w istotny sposób wpływają na proces uzbrajania odwiertów oraz właściwości uskoków. W konsekwencji badania wymaga oddziaływanie trajektorii otworu i zmienionych naprężeń i jego wpływ na stabilność otworu. Dlatego istotnym staje się zrozumienie naturalnych procesów geomechanicznych zachodzących w złożu podczas procesu wydobycia jak również sposobów ich wykorzystania dla zwiększenia produktywności złoża. Jednocześnie pozwala ono uniknąć kosztownych błędów w procesie wiercenia i eksploatacji. W tym celu skonstruowano modele geomechaniczne typu 4D złóż obejmujące dane geologiczne, petrofizyczne, laboratoryjne oraz dotyczące przepływów i geomechaniki, które pozwoliły określić równowagowy rozkład naprężeń zarówno przed jak i w trakcie eksploatacji. Wyniki te mogą być wykorzystane dla określenia optymalnych parametrów wierceń takich jak lokalizacje i trajektorie otworów czy wymagane gęstości płuczki.

Opis:
Visible light communication based on a filter bank multicarrier holds enormous promise for optical wireless communication systems, due to its high-speed and unlicensed spectrum. Moreover, visible light communication techniques greatly impact communication links for small satellites like cube satellites, and pico/nano satellites, in addition to inter-satellite communications between different satellite types in different orbits. However, the transmitted visible signal via the filter bank multicarrier has a high amount of peak-to-average power ratio, which results in severe distortion for a light emitting diode output. In this work, a scheme for enhancing the peak-to-average power ratio reduction amount is proposed. First, an algorithm based on generating two candidates signals with different peak-to- average power ratio is suggested. The signal with the lowest ratio is selected and transmitted. Second, an alternate direct current-biased approach, which is referred to as the addition reversed method, is put forth to transform transmitted signal bipolar values into actual unipolar ones. The performance is assessed through a cumulative distribution function of peak-to-average power ratio, bit error rate, power spectral density, and computational complexity. The simulation results show that, compared to other schemes in literature, the proposed scheme attains a great peak-to-average power ratio reduction and improves the bit the error rate performance with minimum complexity overhead. The proposed approach achieved about 5 dB reduction amount compared to companding technique, 5.5 dB compared to discrete cosine transform precoding, and 8 dB compared to conventional direct current bias of an optical filter bank multicarrier. Thus, the proposed scheme reduces the complexity overhead by 15.7% and 55.55% over discrete cosine transform and companding techniques, respectively.

Opis:
Density and diversity of Fusarium species and other fungi associated with rhizosphere and rhizoplane of lentil and sesame plants at three different growth stages were investigated. Sixteen species of Fusarium were isolated from rhizosphere (13 species) and rhizoplane (11) of both plants studied. In lentil, 11 species were recorded from its rhizosphere (9 species) and rhizoplane (8). Fusarium species associated with lentil rhizoplane gave highest number of propagules at the first stage of plant growth while the ones of Fusarium associated with the rhizosphere produced the highest number at the second stage of growth. F. solani was the most common in the three growth stages. In addition, of two growth stages, F. culmorum and F. tricinctum were isolated from the rhizosphere while F. nygamai and F. verticillioides from the rhizoplane. The other species were recorded from only one growth stage of lentil plant. In sesame plants, rhizosphere yielded nine Fusarium species while rhizoplane gave only six from the three stages investigated. Stage I of sesame rhizosphere possessed the highest colony forming units of Fusarium. As the case for lentil, F. solani was the most common species in sesame rhizospere and rhizoplane. F. verticillioides and F. nygamai (in three different growth stages) followed by F. oxysporum and F. tricinctum (in two growth stages) were recorded using the dilution-plate and/or soil-plate methods from sesame rhizosphere soils. Rhizoplane Fusarium species of sesame plants were isolated at the three different growth stages with almost equal number of colony forming units. F. poae came after F. solani in its frequency since it was recovered from two growth stages. Several of the isolated species are well-known as pathogens to many cultivated plants. To the best of our knowledge, three species are recorded here for the first time in Egypt from the rhizosphere (F. acutatum), rhizoplane of sesame plants (F. longipes) and from rhizosphere of both lentil and sesame and rhizoplane of lentil (F. nygamai).
