The study involved 400 students of the engineering bachelor's degrees, one hundred and, from the second to the fifth year, which has been evaluated for the academic stress and to study skills. A random sample is used to select objects for the study of the system. Three tools were used: Tool I: Socio-demographic Profile Sheet, Tool II: Study Skills Assessment Questionnaire, Tool III: Perceived Stress Scale. The results of this study showed that the students performed well in all the subjects, except for the time-management method and writing skills. More than two-thirds of the surveyed students have a low level of stress. Academic stress is higher in senior and female students. There was a negative correlation between the students' stress and their study skills. Statistically significant relationships were found between academic performance, study skills, and the stress level of the students surveyed.

Abstract: Audiovisual language is a more abstract and vivid way of thinking and emotional expression than written language. It requires the subject to see with eyes, listen with ears, feel with heart, act on the brain and sublimate perceptions An abstract language of intuition. The communication medium of this language is sound and light. It is an artistic language, a language based on vision and hearing, and a sensory language form that affects the subject's psychology through the subject's physiological response. In many cases it can play a role that words can't. Susan Lange once said: "Art is the creation of human emotional symbolic form." ^[1] is more excellent in rendering attractiveness and atmosphere. The three points are: 1. It is a very standard language that is both derived from life and higher than life, and it has a good interpretation of life; 2. It is an abstraction of language, which may be a language of self-made , Is full of longing and fantasy for the future, so that people watching have a kind of confidence in life and foresight of the future; 3. Full of all kinds of exaggerations and prominence, highlighting the problems in reality. Encourage people to look at life from a new perspective, which is thought-provoking.

Abstract: The role of natural pozzolanas is considered to be important especially when the concrete is subjected to acidic, alkaline, saline or waterlogged conditions. Recently, studies on the influence of pozzolanic material on physico-chemical properties of mortar and concrete have received greater attention. Therefore, this research was carried out to evaluate the influence of natural pozzolanas used as partial substitutes for cement on the pozzolanic properties of lime mortar, cement paste, mortar and concrete. Four natural pozzolanas     (i. e., shale, slate, phyllite and volcanic ash) were used as constituent mineral additive in the mortar at the rate of 10, 15 and 20% by mass of cement. In concrete specimens, the pozzolanic replacements were adjusted to 10, 20 and 30% by mass of cement. Compressive strength of the concrete specimens was measured at 7, 14 and 28 days, and flexural strength was measured at the age of 28 days. Lime pozzolana reactivity test was carried out untill 91 days. The use of pozzolanas resulted in substantial reactivity of the limed mortars. The compressive strength of cement paste, mortar and concrete was inversely proportional to the amount of pozzolana replaced. As expected the compressive strength of all specimens increased with time.  Replacement with phyllite and shale improved the strength of pastes and mortars better than with slate and volcanic ash irrespective of the specimen type. Water absorption capacity of cement paste specimens decreased but the setting time and density were enhanced by the substitution with pozzolana.

Abstract: The creation and the operation of the underground gas storage facility (UGSF) is the important task for the reliability of operation of gas transmission systems, uninterrupted supply of consumers by gas a covering of seasonal unevenness of gas consumption at peak demand. At the most cold periods of the winter UGSF can provide to 30% of daily supply of gas for all Russian consumers. Decades of operation of the gas storages created in porous layers, allowed to reveal high heterogeneity and instability of wells’ operation. The main reasons of the heterogeneity of work of UGSF are: heterogeneity of filtration-capacitive properties of layer collector (object of operation);   the uneven drainage of layer collector;   different technical conditions of wells;  the formation of cones during the flood in the period of extraction of gas;   lateral implementation of formation water. In this case the development and the application of the methods of the determination of the effective technological mode of operation of single underground gas storage facilities is the actual task for the research activities.

Abstract: Desmoplastic fibroma (DF) of bone is an extremely rare benign intra-osseous aggressive bone tumour with high risk of recurrence. The neck of femur is an extremely rare location of such tumour. We present a case of young Omani female patient with lytic lesion over the left neck of the femur that clinical and radiological favour diagnosis of aneurysm bone cyst with the initial histopathology examination on core biopsy was insufficient bloody material. Accordingly, extended curettage and bone graft with dynamic hip screw fixation were done. The final histopathological diagnosis on the curettage material was consistent with desmoplastic fibroma of bone. Although, desmoplastic fibroma of femoral neck is an extremely rare, it should be considered in our differential diagnosis with radiological lytic soap bubble lesion especially when the initial sample is insufficient and special attention to MRI, T2 shortening is needed.

Abstract: Aircraft design is a highly nonlinear problem and inherently multidisciplinary activity that involves thousands of design variables and different models and tools for various aspects of design.  A spreadsheet based genetic algorithm (GA) approach is presented to optimize the preliminary design of an aircraft.  A domain independent general purpose genetic algorithm is proposed to implement the optimization routine.  Objective function used for the design evaluation is the Breguet.  A total of sixteen design variables are considered in the optimization process.  It has also been demonstrated that the proposed approach can be adapted to any objective function without changing the optimization routine.  The model is applicable to commercial airliner as well as a multirole jet fighter.  The proposed model has been validated against known configurations of various aircraft.
