Opis:: This work addresses to joining aluminum alloy AA6061 to carbon steel AISI 1006 sheets using the friction spot joining technique. The steel sheets were pre-holed and threaded with an internal M6 thread. The joining process was carried out by extruding the aluminum through the steel hole and thread using a rotating tool with friction between the tool and aluminum. Three process parameters were used: pre-heating time, rotating speed and plunging depth of the tool, with four levels for each parameter. The results indicated that the two materials joined by a micro-scale mechanical interlock at an interface line of a width ranged between 0.7 to ~ 2.5 mm. The joint’s shear force reached a minimum and maximum value of 2000 and 2500 N, respectively. The plunging depth was the most effective factor affecting the amount of the extruded aluminum and the joint’s shear force.

Opis:: The rapid and uncontrollable cell division that spreads to surrounding tissues medically termed as malignant neoplasm, cancer is one of the most common diseases worldwide. The need for effective cancer treatment arises due to the increase in the number of cases and the anticipation of higher levels in the coming years. Oncolytic virotherapy is a promising technique that has shown encouraging results in several cases. Mathematical models of virotherapy have been widely developed, and one such model is the interaction between tumor cells and oncolytic virus. In this paper an artificially optimized Immune-Linear Quadratic Regulator (LQR) is introduced to improve the outcome of oncolytic virotherapy. The control strategy has been evaluated in silico on number of subjects. The crow search algorithm is used to tune immune and LQR parameters. The study is conducted on two subjects, S1 and S3, with LQR and Immune-LQR. The experimental results reveal a decrease in the number of tumor cells and remain in the treatment area from day ten onwards, this indicates the robustness of treatment strategies that can achieve tumor reduction regardless of the uncertainty in the biological parameters.

Opis:: 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).

Opis:: Introduction and Objective. Interferential current IFC is one of the common electrotherapeutic modalities used in the treatment of painful conditions. Patients with musculoskeletal pain seek medical help in order to reduce their pain that could be achieved using IFC. The current review aims to analyze the recently available information regarding the efficacy of the IFC in alleviating the pain of musculoskeletal origin. State of knowledge. IFC, as one of the medium frequency currents, has the advantage of being more comfortable and deeply penetrating so that it can reach deeper painful tissues. It has been proposed that IFC can relieve pain through stimulating different body mechanisms, such as the gate mechanism and the release of body opioids. However, the evidence behind the effectiveness of IFC as a pain-relieving modality for musculoskeletal pain has been poorly studied and still not conclusive. Conclusions. This systematic review will summarize the effects of IFC on relieving musculoskeletal pain as reported through improvement in visual analog scale, numeric pain rating scale, or the McGill pain questionnaire. Through searching multiple databases and including randomized controlled trials published during the last ten years, the findings of the current systematic review and meta-analysis will establish the quality of the recently available evidence and demonstrate if there will be a need for further studies.

Opis:: A pulsation heat pipe is an efficient heat pipe used in many engineering applications. This study aims to test the effect of working fluids on the thermal performance of pulsation heat pipe. Seven turned pulsation heat pipes were designed and manufactured from a copper pipe with a 3.5 mm inner diameter. The lengths of an evaporation part, an adiabatic passage, and a condenser part were 300 mm, 210 mm, and 300 mm, respectively. In this study, three different fluids were used as the working fluid: distilled water, methanol, and binary fluid (a mixture of water and methanol) with a 50% filling ratio. Compared to water, the experimental results suggested that methanol had a better thermal performance when used as a working fluid in the PHP. On the other hand, a binary fluid enhanced the lower thermal performance of water (29% reduction in the thermal resistance and a 20% increase in the effective thermal conductivity of the PHP).

Opis:: The hospitals close to the residences can make problems for the environment as a consequence of sewage drained into the water stream. Sequencing batch biofilm reactor (SBBR) offers advantages for treating sewage; such as simple operation, flexible process, and cost-effective. The laboratory bench-scale experiments were carried out treating hospital wastewater (HWW) of one of Basrah hospital city by a fabricated SBBR reactor of 26 l working volume. The hospital wastewater has the following characteristics (average values): pH 7.3, BOD equal to 280 mg·l–1, COD equal to 550 mg·l–1, total phosphorus (TP) equal to 6.4 mg·l–1, ammonia (NH3-N) equal to 44 mg·l–1 and total suspended solid (TSS) equal to 272 mg·l–1. This research aims to estimate the performance of the SBBR system for treating hospital wastewater to enhance different effluent parameters such as COD, total nitrogen (TN), ammonia, and total phosphorous (TP) with various dissolved oxygen (DO) with range of 2.15–6.55 mg·l–1, the best DO values give these removal efficiencies for COD equal to 84.55%, NH3-N equal to 65.91% and TN between 78 and 18% for DO equal to 3.67 mg·l–1, while TP removal efficiency was 79.70% for DO equal to 6.55 mg·l–1. By comparison of the SBBR effluent with international standards for effluent sewage, it noticed COD concentration 85 mg·l–1, TN 12 mg·l–1 and TP 1.3 mg·l–1 met all standards (European, WHO, and China), while NH3-N 15 mg·l–1 was outside WHO and European standards, while satisfies only Chinese standard.

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.
