Opis:: The present research is aimed at examining the relative importance of the competing motivators of the sequencing of reason clauses in a corpus of research articles of applied linguistics. All the finite reason clauses accompanied by their main clauses in this corpus were collected. Random forest of conditional inference trees is the statistical modelling in this study. The findings showed that sentence-final reason clauses outnumber sentenceinitial ones. Moreover, subordinator choice and bridging, which are discourse-pragmatic constraints on clause positioning, emerged as the two more powerful predictors of the ordering of reason clauses in this corpus. Furthermore, the complexity of the clause turned out to be a stronger processing-related predictor than the length of the clause.

Opis:: The present work proposes several pre-injection patterns to reduce nitrogen oxides in the Wartsila 6L 46 marine engine. A numerical model was carried out to characterise the emissions and consumption of the engine. Several pre-injection quantities, durations, and starting instants were analysed. It was found that oxides of nitrogen can be noticeably reduced but at the expense of increasing consumption as well as other emissions such as carbon monoxide and hydrocarbons. According to this, a multiple-criteria decision-making (MCDM) model was established to select the most appropriate parameters. Besides, an artificial neural network (ANN) was developed to complement the results and analyse a huge quantity of alternatives. This hybrid MCDM-ANN methodology proposed in the present work constitutes a useful tool to design new marine engines.

Opis:: Traditional traffic control systems based on traffic light have achieved a great success in reducing the average delay of vehicles or in improving the traffic capacity. The main idea of these systems is based on the optimization of the cycle time, the phase sequence, and the phase duration. The right-of-ways are assigned to vehicles of one or several movements for a specific time. With the emergence of cooperative driving, an innovative traffic control concept, Autonomous Intersection Management (AIM), has emerged. In the framework of AIM, the right-of-way is customized on the measurement of the vehicle state and the traffic control turns to determine the passing sequence of vehicles. Since each vehicle is considered individually, AIM faces a combinatorial optimization problem. This paper proposes a dynamic programming algorithm to find its optimal solution in polynomial time. Experimental results obtained by simulation show that the proper arrangement of the vehicle passing sequence can greatly improve traffic efficiency at intersections.

Opis:: Antibiotics are used for postsurgical wound healing purposes but unfortunately, resistance against them demands some alternatives for quick recovery. Sepsis of wounds is a challenge for medical as well as veterinary professionals. Nanoparticles have significant advantages in wound treatment and drug resistance reversal. This study was conducted to appreciate emerging alternates of antibiotics like zinc oxide nanoparticles and plant extracts in topical application. Zinc oxide is considered a good wound healer and its nanoparticles are easy to access. So, the efficacies of zinc oxide nanoparticles and sweet flag plant extract ointments were tested to compare modern and traditional therapeutics as sweet flag is considered a pure medicinal plant. Rabbits were selected for this study due to the healing properties of their skin. Wounds were inflicted on the thoracolumbar region and treated for 29 days post-surgically daily with normal saline and the ointment of zinc oxide nanoparticles and sweet flag extract ointment, prepared in a hydrophilic solvent. Wound shrinkage was observed daily and histopathological analysis was made and results were compared. Zinc oxide nanoparticles ointment showed the most satisfactory results for every parameter included in the study. No side effects of its topical application were observed. Healing was normal without any complications. The preparations of zinc oxide nanoparticles may help in the era of antibiotic resistance as topical drugs in the future.

This study investigates the cytotoxic effect of V. iphionoides essential oil on breast (MCF7), prostate (PC3), and chronic myelogenous leukemia (K562) and normal human fibroblast cell lines using MTT assay and flow cytometric analysis. In addition, GC-MS of the oil was carried out. The IC50 values for PC3, MCF7, K562 and fibroblast were 145.3, 188.8, 87.88 and 173.3 µg/ml, respectively. V. iphionoides essential oil was most effective against K562. Flow cytometric results for IC50 dose of V. iphionoides oil on K562 cells showed 32.2 % apoptosis in 24 h. GC-MS analysis resulted in the identification of 25 compounds. 1,8-Cineole, borneol, and α-cadinol were the major constituents of V. iphionoides volatile oil. In conclusion, this study reveals for the first time the cytotoxic activity of V. iphionoides essential oil on K562 cell line which may occur through apoptosis induction.

Opis:: The Basrah province (southern of Iraq) was interested in establishing desalination plants to provide drinking water due to the high levels of salinity in its water resources. This work was carried out in order to evaluate and simulate the functionality of the reverse osmosis plant in the Al-Maqal port. From the field and laboratory measurement, this study concluded that the considered parameters of product water by reverse osmosis (RO) plant were within the Iraqi standard (IRS) limits. The calculation of operation indices showed that the recovery rate of plant (72%) and the permeate flux of plant (20 lmh) was within for limitation of brackish surface water. In turn, the plant has a low salt rejection (90.1%) and a high pressure drop (5 bar); therefore, the membranes require backwashing or chemical cleaning. Then, the performance of RO membrane was simulated by the Winflows software. The best operating parameters were identified. The coefficient of determination (R2) between simulated and measured TDS was 0.83. Therefore, the simulated TDS of permeate multiplied by 5.3 was given a good estimation for actual TDS within acceptable an error rate of 17%.

Opis:: Shatt Al-Arab River in Basrah province, Iraq, was assessed by applying comprehensive pollution index (CPI) at fifteen sampling locations from 2011 to 2020, taking into consideration twelve physicochemical parameters which included pH, Tur., TDS, EC, TH, Na+, K+, Ca+2, Mg+2, Alk., SO4-2, and Cl-. The effectiveness of multiple linear regression (MLR) and artificial neural network (ANN) for predicting comprehensive pollution index was examined in this research. In order to determine the ideal values of the predictor parameters that lead to the lowest CPI value, the genetic algorithm coupled with multiple linear regression (GA-MLR) was used. A multi-layer feed-forward neural network with backpropagation algorithm was used in this study. The optimal ANN structure utilized in this research consisted of three layers: the input layer, one hidden layer, and one output layer. The predicted equation of the comprehensive pollution index was created using the regression technique and used as an objective function of the genetic algorithm. The minimum predicted comprehensive pollution index value recommended by the GA-MLR approach was 0.3777.

Opis:: Security as one of the human's critical needs assumes importance. Security lays the ground for development in various economic, social and cultural dimensions; for this, it is of high significance to measure it. The goal of the current research was to assess sense of security and its role in the expansion of tourism with emphasis on communicative planning components in coastal cities. The research methodology used in this paper was a case study and the information gathering method was document based and it fell in survey types. In document based method, domestic and foreign credible books and researches were applied and in the survey type method, too the tool of questionnaire has been used for gathering information. The statistical population in this research consisted of all tourists who had travelled to the city of Bandar Abbas with some economic, social, political, scientific, and cultural and entertainment aims. The number of 384 tourists was selected as the sample. While analyzing data, T test statistical tests were used for examining the research hypotheses. The result arising from the examination of the research's questions and hypotheses revealed that current tourists in the city of Bandar Abbas enjoy a favorable level as to the sense of security and in comparison between female and male tourists; the latter enjoys higher average of sense of security. Of among the eight hypotheses raised in the research, sense of security of tourists is not only significantly related with age and educational degree while it has a significant relationship with other variables including, the presence of tourists in the city, later travels to the city, choosing of the place of tourism, sense of satisfaction with the travel, gender and income. This is indicative of the fact that the more sense of security increases among tourists, and the more this issue circulates among them, the more tourists' presence and their tendency to reside in the city and even their later travels to the city of Bandar Abbas will increase, because security is found to be the most fundamental factor for tourism development in each city and region that aims to conforms with the features of superior regions within the tourism industry. Development of the tourism industry in each city, though is a product of appropriate security conditions, this means stability of security of that particular in that region.
