Authors: Smyth Joshua M , Johnson Jillian A , Auer Brandon J , Lehman Erik , Talamo Giampaolo , Sciamanna Christopher N 
Published: September 2018

Background
Positive affect journaling (PAJ), an emotion-focused self-regulation intervention, has been associated with positive outcomes among medical populations. It may be adapted for Web-based dissemination to address a need for scalable, evidence-based psychosocial interventions among distressed patients with medical conditions.

Objective
This study aimed to examine the impact of a 12-week Web-based PAJ intervention on psychological distress and quality of life in general medical patients.

Methods
A total of 70 adults with various medical conditions and elevated anxiety symptoms were recruited from local clinics and randomly assigned to a Web-based PAJ intervention (n=35) or usual care (n=35). The intervention group completed 15-min Web-based PAJ sessions on 3 days each week for 12 weeks. At baseline and the end of months 1 through 3, surveys of psychological, interpersonal, and physical well-being were completed.

Results
Patients evidenced moderate sustained adherence to Web-based intervention. PAJ was associated with decreased mental distress and increased well-being relative to baseline. PAJ was also associated with less depressive symptoms and anxiety after 1 month and greater resilience after the first and second month, relative to usual care.

Conclusions
Web-based PAJ may serve as an effective intervention for mitigating mental distress, increasing well-being, and enhancing physical functioning among medical populations. PAJ may be integrated into routine medical care to improve quality of life.

Published: September 2018

Introduction: Cardiovascular disease remains the main cause of death in the world, and myocardial infarction represents the main contributor to this mortality. Timely restoration of myocardial blood flow with reperfusion therapy is crucial. Pre-hospital delay is a major obstacle for early reperfusion therapy and has negative impact on mortality and left ventricle function.
Methods: A prospective study was carried in cardiology unit of a medical college from August 2013 to December 2017. Cases of acute ST segment elevation myocardial infarction that have undergone thrombolysis were recruited.
Results: Out of 450 patients with ST Elevation Myocardial Infection (STEMI), delayed presentation was seen in 288 (64%) for >6 hrs and 108 (24%) patients for >12 hrs. The duration from onset of symptoms to the presentation in the emergency room (pre-hospital delay) was 12.66 hrs (SD=14.19, range = 30 min to 72 hrs). The door to needle time was 54 min (SD=24) The major factors for pre-hospital delay were misinterpretation of symptoms (59%) and transportation problems (31%).
Conclusion: Misinterpretation of symptoms remain the most common cause of delayed presentation. Health education for public awareness can reduce the delay. Extension of thrombolytic therapy to district hospital and primary health center level after basic training for medical officer with checklist and collaboration in form of telemedicine with referral cardiac center may have major impact on morbidity and mortality reduction in acute STEMI patients with early reperfusion therapy.

Trace elements and REE enrichment at Seboah Hill, SW Egypt
Authors: Hassan Kamaleldin M. 
Published: September 2018

Abstract
Seboah Hill - a small body of peralkaline granite (< 0.1 km2) in south-western Egypt containing aegirine minerals ± magnesiohornblende ± riebeckite, cut by dikes of riebeckite-aegirine rhyolite, and exhibiting high radioactivity in veins of K-feldspar-aegirine-chalcedony-quartz ± trace hematite ± trace goethite was sampled and analyzed using inductively coupled plasma methods. Whole-rock chemical compositions of 5 granite, 3-rhyolitedike and 10 radioactive vein samples are presented. Of special significance is the enrichment of trace elements and rare earth elements (REE) in the radioactive veins. These include up to 6081 ppm Zr, 4252 ppm Ce, 1514 ppm Nd, 1433 ppm La, 1233 ppm Nb, 875 ppm Y, 388 ppm Pr, 350 ppm Th, 222 ppm Sm, 189 ppm Gd, 159 ppm Dy, 153 ppm Hf, 83 ppm Er, 76 ppm Yb and 58 ppm U. The chondrite-normalized patterns of REE in all samples show only limited variation and have negative europium (Eu) anomalies. These findings suggest that the sources of the REE are genetically related. Values of the Eu anomalies vary from 0.38-0.41 for the radioactive veins, 0.39-0.53 for the granite and 0.31-0.44 for the rhyolite dikes. Eu variations are consistent for different paragentic stages.

Published: September 2018

Abstract
Introduction: The upper C1-C2 column is the subject of several erroneous diagnostics. The most common mechanisms of injuries include fall from high-impact skulls, car accidents, etc. Vertebra C1 can also be injured by mild trauma. The Japanese show that atlas fractures occur in about 2-13% of the cervical spine fractures and about 1.3% of the total spinal cord injuries. It is underlined that CT examination is the most useful diagnostic method. The Czechs show that the atlas lesions appear in 1-2% of the cervical spine lesions. Americans reported fracture of the atlas in 7% of the cervical spine fractures. Even if CT has shown its value, lateral radiography is recommended in C1-C2 fractures. When victims are children or people injured in high-speed car crashes, the reported mechanisms were the fall from a high level and the impact on the tip of the flexed skull. The Italians mention that the C1-C2 area is the most exposed diagnostic area with errors. Material and methods: given the difficulty of establishing a diagnosis of C1 type fractures, we present in this paper such a case. We highlight the value of a CT scan. The victim is a 26-year-old woman with a trauma from the wall. The main issue in this case is that the diagnosis made by the radiologist seems to be wrong, the electronic and imprinted copies are of inferior quality. A second opinion revealed a very fine fracture that seemed to come from an older date than the date when the victim claimed she was assaulted. The better the lesions, the more misleading the interpretations. Any imaginary imaging lesion, especially if it is obvious in electronic reconstructions, must be brought to the attention of the physician if they are taken into account by "image". The axial CT sections may omit some lesions under certain conditions, for example at the upper and lower poles of a spherical, ovoid or cubic structure, such as the atlas lateral mass. Conclusions: the diagnostic solution in this case is the reconstruction of the axial sections in several planes. The crack can be highlighted, in the case of a reconstructed image, only after stacking the axial images. The mechanism could be through sudden compression, during a sudden head movement, uninitiated and uncontrolled by the neck muscles, when a movement occurs over the degree of elasticity of the occiput-atlas joint, the occipital condyles compressing abruptly, unilaterally one of the atlas masses. In such clinical cases, we experience pain, muscle contraction and torticollis, on a normal neurological background.

Published: September 2018

Abstract
Hemangioblatomas are low grade, highly vascular tumors usually associated with VHL syndrome and most commonly occurs in the cerebellum. They very rarely occur in the spinal nerve roots and an origin in the filum terminale is exceptionl. A 47 year old man presented with low back pain, paresthesias and stiffness of the both lower limbs. He also had urinary retention and constipation. MRI showed an enhancing mass at the L5 vertebral level with multiple dilated and tortuous vessels at both poles of the tumor. Digital subtraction angiogram showed the tumor to be supplied by the anterior spinal artery and dural branches of lumbar arteries. At surgery, a well-defined tumor with orange red hue was found to be arising from the filum terminale. The tumor was excised en bloc. Histopathological examination showed hemangioblastoma which was confirmed with immunohistochemistry. Clinical symptoms improved significantly after surgery. A sporadic hemangioblastoma arising from the filum terminale should be considered as a rare cause of back pain and sciatica. Total excision of the tumor usually cures the patient.

Abstract
The problem is a continuation of the research conducted at the University of Warmia and Mazury in Olsztyn, Institute of Building Engineering. It concerns the development of methods for the interpretation of the shear modulus measurements based on the tests conducted on a torsional shear (TS) apparatus. The issue has significant importance in determining the deformation parameters, essential to perform numerical simulations of the interaction between a geotechnical structure and the subsoil. The purpose of this study was to conduct a comparative analysis of the various methods of interpretation of research results based on direct and reverse analysis, as well as automated classification of the first cycle of the relationship between the shear stress and the shear strain components obtained from the TS test. The methodology for verification of the presented interpretative methods consists in carrying out a series of laboratory tests on non-cohesive and cohesive samples of different granulation and state parameters. The course of the research includes the following steps: elaboration of the granulometric composition of several samples of soil, determination of soil index properties and execution of TS tests. Various methods of interpretation of obtained results were taken into account, in addition to conducting a comparative analysis. The study used a non-standard interpretation approach consisting of analysing one-fourth of the hysteresis loop of the first load–unload cycle of the tested samples. The obtained results confirmed the hypothesis that it is possible to estimate the degradation value of the shear modulus based on a part of the TS test results carried out under quasi-monotonic load conditions. The proposed methods of interpreting test results have confirmed their high usefulness, which is devoid of the uncertainty associated with standardised resonant column/TS testing.

Published: September 2018

Introduction. Nowadays there is sufficient number of the working bodies’ parameters, which allow performing technological operations in different conditions with minimal labor and energy resources. It is necessary to produce significant excavation during roads’ construction. Therefore, to perform such technological procedure excavation and road machinery are used. The motor grader is an earth-moving machine and is necessary for surface profiling, moving and construction materials’ level.The motor grader efficiency is determined by the performance criterion. World producers of earthmoving and road machinery associate the growth of quality and speed of work with the improvement of the executive working bodies. Moreover, new design variants of dumps are being developed, including design variants for motor graders. Such solution would allow to reduce the necessary number of passages along the construction site and to shorten the time for mounting the working body. The article presents the variant of the motor grader working equipment improving by installing the side working dump.Materials and methods. The calculated dependences of the main parameters of the motor grader are obtained, such as the coupling weight, the nominal traction force, the resistances arising in the operating mode when cutting and moving the ground, and the total engine power for the operating mode at 4 km per hour speed. Strength characteristics of the side working equipment of the motor grader are investigated. The analysis is carried out by using the Solid Software.Results. The results of the theoretical studies are presented graphically and reflected the stresses, displacements and deformations in proposed lateral working equipment of the motor grader. Using the Solid Works software product it is possible to determine the safety margin of the proposed design. The conducted research allows confirming the working capacity of the proposed technical solution.Discussion and conclusion. The proposed technical solution allows increasing the productivity of the machine while performing the planning works, while maintaining the specified accuracy of their implementation. In addition, such design allows profiling not only the horizontal surface, but also the embankment construction when the side blade is located at an angle of up to 20 degrees.

Published: September 2018

Introduction. Increased technical requirements for roads, associated with increasing axial loads, the intensity and speed of vehicles, with the actual technical condition of the roads number, engineering structures, including culverts, activation of federal and regional services to bring the parameters of road surfaces to the world standards, all listed parameters pose the task in developing the mathematical modeling methods of physical-mechanical characteristics of soils in the culverts area. Therefore, such methods allow to reduce economic costs and time for carrying out experimental research of deformations based on the monitoring results of the soil roadbed and pavement.Materials and methods. The order of technical condition of the culverts’ research, pavement and physico-mechanical characteristics of soils, methods of experimental research were discussed in the article. Moreover, the approach to carrying out experimental works on penetration of pits in places of deformations and nearby was approved. Additionally, the evaluation of the soils condition on the roadbed and the annular space of the culverts was made.Results. The schemes of deformation and elasticity, density, humidity, consistency, plasticity number, fluidity, and physical properties of the soil are determined. The engineering-geological elements, mean values of density, humidity and compaction factor are established according to the research aim. Consequently, the values of the strain modules and the modulus of elasticity are calculated on the basis of compression and stamp tests.Discussion and conclusions. The dependence of the pavement on the physic-mechanical characteristics of the soil of the roadbed is proved. The correlation-regression analysis of soil characteristics is performed on the basis of experimental research. As a result, the regression equations are obtained in the annular space of culverts and at the distance of ± 30 m nearby. As could be proved, there are irregularities in the coverage of road clothes caused by drawdown in barrier locations. The physic-mechanical characteristics of the ground and strength characteristics are increased by culverts’ transfer on distance. The application of physic-mechanical characteristics of the soil together with experimental studies makes it possible to reduce labor costs, time and cost of testing.

Authors: Ckhum A. 
Published: September 2018

Introduction. Evaluation of the influence level of the pre-organized cracks in tensile zone of the reinforced concrete beams on their crack resistance, deformability under long-term loading is investigated in the article.Materials and methods. Concrete for specimen was produced in laboratory and factory on portland cement of the 500-grade at W/C=0,71; concrete composition 1:1,9:4 (by weight); strength of cube at 28th days – 13,85 MPa; strength of prism with dimensions 10/10*40 cm – 11,48 MPa; span calculation – 78 cm; steel rebar grade – A400 with diameter of 10 mm. Organized crack was formed by installing plate with thickness of 0,5 mm and height of 30 mm on the rebar in the zone of maximum moments.Results. The experiments confirmed the hypothesis about the beams rigidity with pre-organized cracks in comparison with stochastic cracks under the influence of long-term loading. As a result, the beams with pre-organized cracks provide the smaller deflection after long-term period than the beams without organized cracks. Thus, the proposed method of the deflections calculation of the reinforced concrete beams with pre-organized cracks under the long-term loading helps to reduce deflection to 33%.Discussion and conclusion. The findings of this study suggest that the presence of pre-organized cracks reduces the beams deflections in comparison with the specimens of section, and such method actually regulates the stress-strain state of reinforced concrete structures and leads to the smooth deformation at all stages under the influence of long-term loading.

Authors: J. Alabidi Abdulkadhim 
Published: September 2018

The study area situated in the western part of Zagros fold-thrust belt, north east (NE) Iraq. Google earth image for study area was used to build up lineaments map. Studying and processing of these lineaments revealed that there are two dominant directions of lineaments northeast-southwest (NE-SW) and northwest- southeast (NW-SE), compatible with the main regional stress direction and Zagros belt direction respectively. It was found that there is no significant change of lineaments density in different tectonic zones and there is no obvious effect of lithology on lineament density in the study area. Length rose diagrams showed an obvious increase in the value of NW-SE lineaments direction, starting from low folded zone toward NE, despite frequency rose diagrams of different tectonic zones showed no significant change of the main prevailing direction. It is found that some lineaments shifted or bended some folds or ridges in the study area. Field observations demonstrated that some lineaments of study area had field criteria of faults while they did not described in tectonic map.

Published: September 2018

Abstract
In VVER-1000/1200 type reactors much higher and geometrically more complex assemblies are applied compared to the VVER-440 design. Additionally, assembly shrouds are not used in the improved reactor types. This implies that the existing sub-channel wise models and hot channel calculation methodologies used in the safety assessment of VVER-440 reactors have to be improved. For this purpose a full core thermal hydraulic model was developed. In the first part of the paper the new model and its connections with the reactor physics of KARATE-1200 code system are demonstrated with results regarding the sub-channel outlet temperature and DNBR. In the second part of the paper the hot channel calculation methodologies to be used in the transient safety analyses of VVER-1200 type reactors are discussed. The appropriate frame parameter concept concerning the limitation of the heating up of the coolant and the single closed sub-channel approach vs. the multi-channel approach are studied, as well.
