Authors: Dhia Ahmed Alazawi
Published: July 2019

The inherent characteristics of electrochemical machining (ECM) have large scale of advantages over the traditional machining technologies. ECM has been employed in this work to machining low carbon AISI1005 steel. Such technique is used to remove the electrical conductive material via a controlled electrochemical anodic reaction regardless of the metal mechanical properties. The considered experiments were conducted to study the effects of process parameters such as applied voltage, electrolyte flow rate, current density on all of weight loss, dissolution rate and material removal rate (MRR) in sodium chloride aqueous solution. The results stated that, the weight loss is in general increased with the voltage and the flow rate as its maximum value was 9.23 g and 5.35g respectively. Increasing the current density has led to obtain maximum MRR and dissolution rate of 0.248g/min and 1.59 mm/min respectively. The results showed that there was an enhancement in the MRR and the dissolution rate so as to be 66.8% and 3.94% respectively.

Published: July 2019

Blue methylsalicylatocopper(II) complex with picolinamide Cu(3-Mesal)2(pnia)2 has been prepared and characterized by elemental analysis and spectral methods. Based on the infrared spectra, monodentate coordination of 3-methylsalicylate anion has been assumed and the coordination variability of the anion has been shown. By determination and refinement of the unit cell from powder diffraction data, the existence of a monomeric Cu(II) complex can be anticipated. EPR spectrum of the complex is in good agreement with these results. The g-factors fulfil the relation g
|| > g
┴ > 2.0023, which is consistent with the dx2 – y2 ground electronic state and indicates coordination sphere of distorted tetragonal symmetry {CuN2O2O2

Published: July 2019

Nonwoven geotextiles are often used in road construction as a separation layer. They consist of the web of fibers with different orientations. The orientation of fibers has an important influence on physical and mechanical properties of nonwoven geotextiles. The production of nonwoven geotextiles is cheaper in comparison to woven or knitted fabrics which can also be used as separation geotextiles. The purpose of this research was to study the influence of structural properties of nonwoven geotextiles, namely the diameter of fibers and mass and thickness of nonwoven geotextiles, on their mechanical and hydraulic properties. Six types of nonwoven geotextiles were used in the research. They were produced by the drylaid process (carded) using mechanical bonding technique and also with the combination of mechanical and thermal bonding technique. The research confirmed that the bonding technique and structural properties significantly influence the separation and filtration properties of nonwoven geotextiles, such as opening size and water permeability. It was also found that there are no significant differences in mechanical properties, such as viscoelastic properties and compression creep, between the samples in the dry and wet conditions.

Published: July 2019

This study was conducted to determine the effects of a low-protein diet supplemented with synthetic amino acids on the biochemical parameters in the blood serum, the indicators of fermentation processes, and nitrogen excretion in 12 crossbred piglets. The piglets (weaned at 28 days of age) were divided into two groups with 6 piglets each. The control group had an initial average body weight of 8.8 ± 0.6 kg and the experimental group with an average initial body weight of 8.6 ± 0.7 kg. The control diet contained 210.8 g.kg−1 crude protein and the experimental diet contained 186.4 g.kg−1. The experimental diet was supplemented with lysine, methionine and threonine to achieve a more ideal amino acid pattern. The blood collections from the sinus ophthalmicus for the determination of the biochemical parameters were performed 4 times at weekly intervals in the control and experimental groups 4—5 hours after feeding. The faeces were taken from the rectum at the end of the study period. The decrease in the dietary crude protein content of the experimental group was manifested by a significant decrease of the blood urea level (2.61 mmol.l−1 average concentration) compared to the control groups (4.21 mmol.l−1 average concentration) (P < 0.001). The other serum component concentrations (total protein, albumin, glucose, cholesterol, total lipids and selected enzymes) showed no significant statistical changes between the control and experimental groups. The results of the fermentation process analysis indicated that the butyrate concentration decreased (P = 0.0017) and the pH increased (P = 0.0180) in the experimental group compared to the control group. The levels of crude protein and ammonia in the faeces of experimental animals were significantly lower (P < 0.001) in comparison with those in the control animals.

Published: July 2019

The aim of this study was to perform an electromyography comparison of three commonly used lower limb injury prevention exercises: a single-leg squat on a bench (SLSB), a double-leg squat (DLS) and a double-leg squat on a BOSU® balance trainer (DLSB). After determining the maximum isometric voluntary contraction of the hamstring and quadriceps, eight female athletes performed 3 repetitions of each exercise, while electromyography activity of the biceps femoris (BF), semitendinosus (ST), vastus lateralis (VL) and vastus medialis (VM) was monitored. Comparisons between exercises revealed higher activation in BF (descending phase: p = 0.016, d = 1.36; ascending phase: p = 0.046, d = 1.11), ST (descending phase: p = 0.04, d = 1.87; ascending phase: p = 0.04, d = 1.87), VL (ascending phase: p = 0.04, d = 1.17) and VM (descending phase: p = 0.05, d = 1.11; ascending phase: p = 0.021, d = 1.133) muscles for the SLSB compared to the DLSQ. Furthermore, higher muscular activation of the ST (ascending phase: p = 0.01, d = 1.51; descending phase: p = 0.09, d = 0.96) and VM (ascending phase: p = 0.065, d = 1.03; descending phase: p = 0.062, d = 1.05) during the SLSB with respect to the DLSB was observed. In conclusion, the SLSB elicits higher neuromuscular activation in both hamstring and quadriceps muscles compared to the other two analysed exercises. Additionally, the higher muscle activation of both medial muscles (ST and VM) during the SLSB suggests that single leg squatting exercises may enhance lower limb medial to lateral balance, and improve knee stability in the frontal plane.

The aims of this study were to assess bone mass in children and adolescent soccer players and to evaluate the influence of both gender and pubertal status on bone mass. A total of 110 soccer players (75 males / 35 females; 12.73 ± 0.65 / 12.76 ± 0.59 years) participated in this cross-sectional study. They were divided into two groups according to their pubertal status. Bone and lean masses were measured with Dual-energy X-ray Absorptiometry. An independent t-test and an adjusted by subtotal lean and training experience multivariate analysis of covariance were used to analyse the differences in bone mass values between genders and maturity status. Female soccer players presented higher bone mass values than their male counterparts in most of the measured weight-bearing sites. Moreover, when stratifying by pubertal status, peripubertal and postpubertal females had higher subtotal body and lumbar spine bone mass than males. Comparing between pubertal status groups before adjustment, both male and female postpubertal players showed higher bone mass than their pubertal counterparts. After adjusting, these differences disappeared and, in fact results were inverted as bone mass at the femoral neck was higher in both male and female peripubertal soccer players than in postpubertal players. Bone mass seems to be more intensely stimulated by playing soccer in female than male players, particularly in the lumbar spine. The results of peripubertal players showing higher bone mass at the femoral neck after adjusting suggest that playing soccer during the peripubertal stage could be an effective activity to achieve optimal bone mass values.

Published: July 2019

Sensing carbohydrates via the oral cavity benefits performance outcomes during brief high intensity bouts of exercise. However, the extent to which carbohydrates need to be present in the oral cavity to influence sprint performance is less understood. The purpose of this study was to determine if serial increases in carbohydrate rinse time across sprint sets attenuates increases in sprint time compared to no serial increases in carbohydrate rinse time across sprint sets. Fifteen sprint trained participants completed three repeated anaerobic sprint tests (RAST), 3 sets of 6 x 35-m sprints, under two different carbohydrate mouth rinsing (CMR) conditions; (1) rinsing for only 5 seconds (s), and (2) rinsing for 5 s, 10 s and 15 s (serial rinse). Prior to a RAST, participants provided perceived recovery status (PRS) and perceived feeling of arousal (FAS). Upon completion of each individual sprint, participants gave a rating of perceived exertion (RPE). A lactate sample was taken upon completion of each individual sprint set and after all 3 RASTs a session rating of perceived exertion (S-RPE) was measured. There were no significant differences in peak (p = 0.18) and average sprint time (p = 0.41). There were no significant differences in perceptual measures: RPE, PRS, FAS, S-RPE or for blood lactate concentration between CMR conditions. Overall, serial rinsing resulted in changes that were most likely trivial, but showed a 50% chance in perceiving a sprint session as less difficult. Rinsing carbohydrates in a serial manner between repeated sprint sets produces trivial changes of sprint speed and perceptual measures from sprint performance.

Published: July 2019

This study assessed gross efficiency (GE) during a single competitive season and determined the relationship between GE and maximum oxygen uptake (V̇O2max) in young elite cyclists (n = 15, 20.1 ± 1.4 yrs, 177.5 ± 5.7 cm, 68.3 ± 6.2 kg, 45.2 ± 7.5 mm of six skinfolds) during a competitive season. Participants completed at two occasions (T1 = April; T2 = July), a progressive bike protocol (initial intensity = 100 W, 35 W increments every 3 min) until volitional exhaustion to assess V̇O2max and submaximal variables. A single capillary blood sample was drawn from the left earlobe immediately after completion of each exercise load to determine lactate thresholds. Cyclists’ GE was calculated as ([work accomplished/energy expended] x 100). No significant differences were obtained in GE at any workload between T1 and T2 or in the mean GE between T1 (19.3%) and T2 (19.4%) testing (p = 0.93). No significant association was found between mean GE and V̇O2max at either T1 (r = -0.28, p = 0.30), or T2 (r = -0.27, p = 0.32). GE of young elite cyclists might not vary during the most important phase of the training season and GE was not related to V̇O2max. A lower accumulated volume and intensity of training of these cyclists may account for their lower GE in comparison to older professional cyclists and might not have been enough to foster higher increases of GE in cyclists with lower V̇O2max.

Published: July 2019

This study aimed to compare the perceived training load (session-RPE) and wellness status (muscle soreness, stress, fatigue, and sleep quality) within and between regular (one-match) and congested (two matches) weeks. Fifteen professional basketball players from a European First league club participated in this study. Wellness status (Hooper’s questionnaire) and perceived training loads (session-RPE) were measured for each training session and matches over a full season. Regular weeks presented moderately greater session-RPE than congested weeks (p = 0.201; d = 2.15, moderate effect). Both regular and congested weeks presented a decrease in perceived training load before matches, which was accompanied by improved wellness status on a match day. Congested weeks presented moderately lower sleep quality (p = 0.421; d = 1.320, moderate effect) and moderately greater fatigue (p = 0.468; d = 1.401, moderate effect) than regular weeks. Regular and congested weeks presented minimum differences for DOMS and stress. Lower wellness in congested weeks may be associated to an accumulative effect of training and match loads. Tapering phases before matches seem to play an important role for improving athletes’ wellness and preventing overtraining.

Published: July 2019

Background: Acute ST-elevation myocardial infarction (STEMI) is an uncommon diagnosis in patients less than 40 years of age. Over the last two decades, there is an increase in the frequency of cardiovascular events among young adults. However, at present there is only limited clinical data on the clinical characteristics and outcomes of STEMI in young patients who were treated with primary percutaneous coronary intervention (pPCI). Plaque erosion is the underlying pathological mechanism leading to STEMI in the vast majority of young adults. Thrombi that complicate superficial erosion seem more platelet-rich than the fibrinous clots precipitated by plaque rupture. Mean platelet volume (MPV) is recognized as a marker of the platelet activation process and may be a better indicator of short-term prognosis than the inflammatory markers in young patients with STEMI. Therefore, we aimed to investigate clinical and angiographic characteristics, risk factors and the independent value of MPV on predicting short-term major adverse cardiovascular events (MACEs) in young adults with STEMI. Methods: A total of 349 patients aged 40 years or younger who underwent pPCI at our center between 2010–2015 with the diagnosis of STEMI were retrospectively analyzed. Results: The mean age of the patients was 36.4 ± 3.6 years and 90% of them were men. Smoking was by far the most frequent cardiovascular risk factor. MACEs were observed in 23 patients (6.6%), and according to the multivariate regression analysis, Killip IIIIV (OR 7.52, 95% CI 1.25–45.24, p = 0.03), lower admission SBP (OR 0.94, 95% CI 0.90–0.98, p <0.01) and increased MPV (OR 1.67, 95% CI 1.05–2.67, p = 0.03) were found to be independently correlated with MACE in the study population. Conclusion: Our results indicate that MPV is an independent predictor of MACEs at the short-term follow-up in young patients with STEMI undergoing pPCI. Accordingly, we suggested that MPV, a marker of platelet activation, could play a significant role in predicting clinical evolution in young patients with STEMI.

Published: July 2019

An assessment of Varuna river basin of India was performed to study the various drainage parameters in GIS platform. The delineation of drainage network is possible either physically from topographic sheets or with the help data of Digital Elevation Model (DEM) by methods for calculation techniques. Extraction of the basin and sub-basins, stream network has been produced to evaluate the drainage characteristics in the study zone. The entire Varuna river basin has been subdivided into 3 sub-watersheds and 41 morphometric parameters have been computed under four broad categories i.e. drainage network, basin geometry, drainage texture, and relief characteristics. The morphometric analysis has been performed and different parameters have been correlated with each other to understand their underlying connection and their role over the basin hydro geomorphology. The study discloses different types of morphometric analysis and how they influence the soil and topography of the basin. The investigation and estimation of basin morphometry and relief parameters in GIS will be of massive utility in catchment area advancement, understanding the watershed for natural resource evaluation, planning and administration at any scale. The outcomes thus generated equip us with significant knowledge and may also provide an input that are essential in decision making for watershed planning and drainage development of the watershed.

Authors: Shpak Nestor , Seliuchenko Nadiya , Kharchuk Viktoriya , Kosar Nataliya , Sroka Włodzimierz
Published: July 2019

Background and Purpose: The existing frameworks provide a superficial approach to the evaluation of product competitiveness which reveals the linkage between the level of product competitiveness and quantitative as well as qualitative factors that have the most significant impact thereon. Given this fact, the purpose of this paper is to elaborate a model for evaluating the competitiveness of sunflower packaged oil, considering both quantitative and qualitative factors that may alter it. Further, this model is being implemented to examine the most demanded Ukrainian sunflower oil brands in order to reveal possibilities for enhancing competitiveness.

Design/Methodology/Approach: The general methodology of the research includes elements of theoretical, empirical, qualitative and quantitative analyses. The theoretical analysis aims to shed light upon a different understanding of “the evaluation of competitiveness”, as well as approaches and tools for analysing it. Empirical analysis focuses on observing official statistical data of the export of sunflower oil and future trends. Qualitative analysis consists in the identification, systematization and description of factors that affect the competitiveness of sunflower oil packaged. In turn, quantitative analysis is based on usage of the Fuzzy logic tool in order to evaluate the impact of complex and partial factors on the level of product competitiveness.

Results: This paper provides a business case for product competitiveness evaluation of a particular sunflower oil brand. Based on usage of the Fuzzy logic toolkit, the impact of complex and partial factors on competitiveness level was analysed. As a result, simulation of the competitiveness sensitivity of a particular oil brand on relevant complex factors that determine it competitiveness level was presented. This business case may help managers to channel their efforts and resources in the proper particular direction to increase product competitiveness and product positioning on the market.

Conclusion: The results of this research would be useful to practitioners in their assessment of product competitiveness, modelling future levels, and understanding hidden possibilities for enhancing product competitiveness. The framework offered might be adopted for other types of products.
American Indian Languages in the Eyes of 17th-Century French and British Missionaries
Authors: Kilarski Marcin
Published: July 2019

This paper examines 17th-century descriptions of Algonquian and Iroquoian languages by French and British missionaries as well as their subsequent reinterpretations. Focusing on such representative studies as Paul Le Jeune’s (1592–1664) sketch of Montagnais, John Eliot’s (1604–1690) grammar of Massachusett, and the accounts of Huron by Jean de Brébeuf (1593–1649) and Gabriel Sagard-Théodat (c.1600–1650), I discuss their analysis of the sound systems, morphology, syntax, and lexicon. In addition, I examine the reception of early missionary accounts in European scholarship, focusing on the role they played in the shaping of the notion of ‘primitive’ languages and their speakers in the 18th and 19th centuries. I also discuss the impressionistic nature of evaluations of phonetic, lexical, and grammatical properties in terms of complexity and richness. Based on examples of the early accounts of the lexicon and structure of Algonquian and Iroquoian languages, I show that even though these accounts were preliminary in their character, they frequently provided detailed and insightful representations of unfamiliar languages. The reception and subsequent transmission of the linguistic examples they illustrated was however influenced by the changing theoretical and ideological context, resulting in interpretations that were often contradictory to those intended in the original descriptions.
Transnationalism as a Decolonizing Strategy? ‘Trans-Indigenism’ and Native American Food Sovereignty
Authors: Kruk-Buchowska Zuzanna
Published: July 2019

The aim of this paper is to analyze how Indigenous communities in the United States have been engaging in trans-Indigenous cooperation in their struggle for food sovereignty. I will look at inter-tribal conferences regarding food sovereignty and farming, and specifically at the discourse of the Indigenous Farming Conference held in Maplelag at the White Earth Reservation in northern Minnesota. I will show how it: (1) creates a space for Indigenous knowledge production and validation, using Indigenous methods (e.g., storytelling), without the need to adhere to Western scientific paradigms; (2) recovers pre-colonial maps and routes distorted by the formation of nation states; and (3) fosters novel sites for trans-indigenous cooperation and approaches to law, helping create a common front in the fight with neoliberal agribusiness and government. In my analysis, I will use Chadwick Allen’s (2014) concept of ‘trans-indigenism’ to demonstrate how decolonizing strategies are used by the Native American food sovereignty movement to achieve their goals.
Employee as a Subject of Sustainable Management
Authors: Zadros Katarzyna
Published: July 2019

In modern companies, an employee is perceived as a particularly valuable asset whose importance increases as the company enters the path of sustainable development. This situation means that a new role is assigned to the employee, he becomes an element of human capital, or the intellectual capital of the organization; he is a stakeholder. What does this actually mean for companies and how can this situation be assessed from the employee‘s perspective? Does the concept of sustainable development influence changes in human resources management, and if so, in which areas are these changes visible in particular? Searching for the answers to these questions will be the goal of the article presented below.
The Effect of Coconut Fibres, Banana Trunk Peel and Baggasse on the Lost Circulation of the Drilling Mud
Authors: Akbar Rizki , Hamid Abdul , Sitaresmi Ratnayu
Published: July 2019

Lost Circulation Materials (LCM) are specially designed not to damage the penetrating formation during handling of loss circulation problems and are very effective for drilling operations worldwide. Optimization of LCM composition may stop loss circulation effectively and protect the production zone from the invasion of mud filtrate. The concentration of lost circulation  materials (LCM) is a key parameter to determine the effectiveness of LCM. In this study, laboratory equipment such as the Hamilton beech mixer, Fann VG meter and API filter press are used to evaluate the effectiveness of various LCMs in dealing with loss circulation. In this research, coconut fibre, banana tree skin, and bagasse are used as LCM in various concentrations. The mud losses were simulated using an 80 mesh shaker. The quality of the muddy rheological properties wasthe basic parameters to be evaluated. The test was carried out at 80oF and 200oF. The experimental results show that bagasse has the best performance both at 80oF and 200oF as LCM compared withcoconut fibres and banana trunk. The lost circulation of  mud filtrate at 80oF and 200oF due to the addition of 2 gram bagasse is 34 ml and 40 ml, respectively.
Optimization of Drillstring Design to Produce More Stable Dynamic Drilling on Horizontal Drilling by Applying Different Stiffness Combinations
Authors: Prasetyo Dundie , Sitaresmi Ratnayu , Prakoso Suryo
Published: July 2019

Horizontal drilling technique is one of the methodologies that have been widely implemented recently to improve the production of oil and gas wells. Several directional drilling technologies can be utilized to drill the horizontal wells, vary from the simple mud motor technology to Bottom Hole Assembly (BHA) with the advanced motorized rotary steerable system. The most common challenges that are faced on horizontal drilling process are on the torque and the stick-slip throughout drilling process, which can be a technical limiter for the length of horizontal section that would be achieved. Stick-slip is the vibration that occurs due to cyclical rotation acceleration and deceleration of the bit, BHA or drill string. This speed fluctuation can be zero to rate of penetration (ROP) or far in excess of twice the rotational speed measured at the surface. Stick-slip can significantly decrease the ROP, increases tool failures and damage, affects borehole quality, and impacts the data acquisition. Several studies had been done on the stick-slip prevention and mitigation throughout creation of new technology and drilling parameters envelope throughout drilling operation, however no study has ever been done on the modification of the design and arrangement of the BHA itself to produce more stable BHA. Drill pipe is the longest component of the drill string and hence it has biggest contribution towards the drill string dynamic. This study will focus on the analysis of the combination of several designs of the drill-pipe and heavy weight drill-pipe (HWDP) that has different stiffness and characteristic to produce less vibration, more efficient drilling operation and to create zero impact on the data acquisition measured while drilling. FEA drilling dynamic simulator was used to optimize the drill sting configuration. The calculation is made from the depth of 750 m to 2801 m. Based on the drilling simulation results of FEA modeling, it is concluded that the minimum stiffness ratio to give stability of the drill string of Well-Z7 BHA and Well-Z6 BHA is 0.012175272 and 0.07366999, respectively.
RESULTS OF STAGED ENDOVASCULAR MYOCARDIAL REVASCULARISATION IN PATIENTS TREATED FOR ACUTE CORONARY SYNDROME WITH ST-SEGMENT ELEVATION AND MULTIVESSEL DISEASE
Authors: Bocharov Alexander V. , Popov Leonid V.
Published: July 2019

Aim. To evaluate the results of complete functional endovascular myocardial revascularisation which is performed early after stenting the culprit artery (within 90 days) with third-generation sirolimus-eluting stents in patients treated for acute coronary syndrome (ACS) with ST-segment elevation and multivessel disease. Materials and methods. We analysed the results of a 2-year follow-up treatment period of patients suffering from ACS with ST-segment elevation and multivessel disease who had undergone urgent stenting of culprit artery. Within 90 days after stenting, a complete functional endovascular myocardial revascularisation was performed using third-generation sirolimus-eluting stents. The efficacy and safety of the procedure was evaluated according to the non-inferiority criteria in comparison with the literature data on myocardial revascularisation by coronary artery bypass surgery. Results. In the course of follow-up treatment, 1 lethal myocardial infarction (after 18 months from complete revascularisation) and 2 non-lethal myocardial infarctions were registered. The symptoms of angina returned in 7 patients, 6 of whom had undergone unplanned re-revascularisation within 6 to 12 months following complete revascularisation. The MACCE rate was 0.143 [95% confidence interval: 0.0770; 0.2497]. Conclusion. In patients having ACS with ST-segment elevation and multivessel disease, endovascular myocardial revascularisation performed early after stenting the culprit artery is equivalent to coronary artery bypass surgery in terms of cardiovascular mortality rates, as well as incidence of non-fatal cardiovascular events. However, such an approach underperforms compared to coronary artery bypass surgery in terms of a composite endpoint of MACCE and the number of required re-interventions.

Monitoring of the circulation of the pathogen shows the presence of serotypes A and B in the region of inﬂuenza viruses. Among hospitalized adult patients, young people, women, with a moderate course of the disease predominate. The highest incidence and severity of inﬂuenza was observed in 2016, when pandemic A(H1N1)pdm09 virus prevailed. There has been an increase in the complicated course of the ﬂu since 2016, despite the diversity of the dominant species of the virus. The leading position among the complications is pneumonia. Conclusion Epidemiological monitoring is the basis of anti-epidemic and preventive measures. In connection with the marked tendency to an increase in the incidence and an increase in the complicated course of the ﬂu, its rapid diagnosis in the outpatient setting for early etiotropic treatment is necessary.

Aim. To study the crystallogenic and initiating potential of biological ﬂuids in rats under normal conditions and when modeling a contact thermal injury. Material and methods. To this end, we used our own model of contact thermal burn. This experiment involved the impact of a hot plate on the back of the animal, with the lesion area amounting to 20% of the body surface (3rd degree burn). This model of thermal injury was reproduced in 30 Wistar rats. 24 hours after the burn experiment, the animals were subjected to blood tests. Subsequently, an evaluation of the blood crystallogenic and initiating properties was performed. The range of basic substances used in teziographic tests was rather conventional and included 0.45, 0.9 and 3% sodium chloride solutions, as well as 0.1 N hydrochloric acid and sodium hydroxide solutions. The results of own and initiated crystallization of biological ﬂuids were evaluated using the authors’ system of semi-quantitative indicators. Results. It is found that, in comparison with intact animals, micro-preparations of dried blood serum from rats after thermal trauma demonstrate a significant inhibition of both own crystallization and that initiated by various basic substances. This phenomenon is manifested in a significant decrease in the index of structural facies (in a crystalloscopic test), the main teziographic coefficient and the belt coefficient. The pathological nature of the observed shifts in the crystallogenic properties of biological ﬂuids emphasizes a sharp increase in the degree of destruction demonstrated by the crystalline elements of the blood samples of rats in the main group. Conclusion. The conducted research shows that a model thermal injury in rats is accompanied by significant shifts in the crystallostasis of an animal organism, which are manifested in a significant change in the crystallogenic and initiating properties of the blood serum.

Identifying the Competence Components of the Construction Project Managers in the Palestinian Construction Industry
Authors: Abdelnaser Omran  , Akram Subhe Hardam Suleiman
Published: July 2019

This study aimed at identifying competency components of project managers of small to medium-sized firms in the Palestinian construction industry and ranking them according to their degree of importance. A postal questionnaire survey was administered to 150 construction companies in Nablus, Tulkarm, and Jenin, which are located in the West Bank. A total of 109 questionnaires were returned, and the response rate was 73 percent. The respondents were project managers. The study identified four competence dimensions, namely, knowledge competence, functional competence, personal/behavior competence, and value/ethical competence. Each dimension is measured by several constituents. Knowledge dimension includes technical knowledge, management knowledge, general knowledge, communication knowledge, computer knowledge, financial knowledge, and legal knowledge constituents. Functional competence dimension includes seven constituents, namely, organizing project initiations, developing a project plan, managing human resource functions, managing project quality health safety and environment, managing design development and contract administration, tracking and controlling system, and administering project close out. Personal competence dimension has two constituents, namely, social-vocational and intraprofessional. Values/ethical competence dimension consists of two constituents, namely, personal values and professional values. Thus, personal competence is in the top ranking followed by functional competence, knowledge competence, and values competence. Finally, a mixture of knowledge, functional, personal, and values competences must be considered to produce a competent project manager in the Palestinian construction industry. This study recommends that the Palestinian Contractors Union and the Palestinian Engineers Association improve the competencies of their members by conducting continuous and up to date construction management training programs by targeting competencies included in this research.
Alternative approach using miniscrew-anchored sliding jig to correct maxillary midline deviation in a patient with unilateral missing premolar
Authors: Shimazaki Kazuo , Kanno Zuisei , Ono Takashi
Published: July 2019

This case report describes the use of a miniscrew-anchored sliding jig (SJ) to distalize molars in a patient with maxillary midline deviation. A 41-year-old female presented with a chief complaint of maxillary midline deviation toward the left caused by prior orthodontic treatment involving unilateral extraction of a maxillary left premolar. Clinical examination revealed facial symmetry and a straight profile. The maxillary midline was deviated 2.5 mm to the left. The patient was treated with molar distalization using miniscrew-anchored SJs. Midline correction and alignment were obtained with maxillary unilateral distalization and mandibular full-arch distalization. The total active treatment period was 32 months. Appropriate occlusion and centered midlines were maintained after 29 months of retention. Our results suggest that the treatment method described herein is effective to distalize the unilateral posterior segment in either arch.

Published: July 2019

Objective

The aim of this study was to assess the effect of fixed orthodontic treatments with steel-ligated conventional brackets and self-ligating brackets (SLBs) on periodontal clinical parameters.

Materials and Methods

Seventy-seven patients (24 male and 53 female) aged between 18 and 30 years were enrolled in the study. Periodontal parameters including plaque index (PI), gingival index (GI), and bleeding on probing (BOP) index were obtained from all the bonded teeth.

Results

When the effect of bracket type and duration of treatment on gingival tissues was examined, there was no statistically significant difference between the treatment times (P = 0.670) and bracket types (P = 0.596) in terms of PI. The GI was significantly different between the different treatment durations (P = 0.045); it was higher in patients with a treatment duration of 18–36 months. However, the GI did not change according to the bracket types (P = 0.270). This result was not significantly different between different treatment durations (P = 0.270). There was no significant difference between the treatment periods (P = 0.189) in terms of BOP index, and this result did not change according to the bracket types (P = 0.621).

Conclusion

SLBs do not require ligatures, which may facilitate plaque accumulation. However, our results showed that SLBs were not advantageous over CBs in terms of periodontal health.
INTRA-SPECIES GROUPINGS OF CHUM SALMON ONCORHYNCHUS KETA (SALMONIDAE) OF THE AMUR RIVER AND THEIR DISTRIBUTION WITHIN THE BASIN
Authors: Zolotukhin S. F.
Published: July 2019

Chum salmon in the Amur River basin are represented by two races: summer and fall ones. For the summer race, one population with specific type of spawning grounds is known, but the fall race includes three populations with different types of spawning grounds. In total, four eco-geographical groupings of the species are separated in their reproduction by geographical boundaries of geomorphological zones, as well as temporally and ecologically. Chum salmon do not spawn in the Chinese part of the Amur basin in more than 50 years. In the Russian part, the summer chum salmon spawn completely in the hyporheic waters in late July — August, the major grouping of fall chum (77.1 %) spawns in the spring waters in September-November, other two groupings spawn in the hyporheic waters of the lower Amur in September (20.4 %) and in the spring waters of the lakes near the Amur mouth in October-November (2.5 %).
A Transferable, Polarisable Force Field for Ionic Liquids
Authors: Goloviznina Kateryna , Canongia Lopes José N. , Costa Gomes Margarida , Padua Agilio
Published: July 2019

A general, transferable polarisable force field for molecular simulation of ionic liquids and their mixtures with molecular compounds is developed. This polarisable model is derived from the widely used CL\&P fixed-charge force field that describes most families of ionic liquids, in a form compatible with OPLS-AA, one of the major force fields for organic compounds. Models for ionic liquids with fixed, integer ionic charges lead to pathologically slow dynamics, a problem that is corrected when polarisation effects are included explicitly. In the model proposed here, Drude induced dipoles are used with parameters determined from atomic polarisabilities. The CL\&P force field is modified upon inclusion of the Drude dipoles, to avoid double-counting of polarisation effects. This modification is based on first-principles calculations of the dispersion and induction contributions to the van der Waals interactions, using symmetry-adapted perturbation theory (SAPT) for a set of dimers composed of positive, negative and neutral fragments representative of a wide variety of ionic liquids. The fragment approach provides transferability, allowing the representation of a multitude of cation and anion families, including different functional groups, without need to re-parametrise. Because SAPT calculations are expensive an alternative predictive scheme was devised, requiring only molecular properties with a clear physical meaning, namely dipole moments and atomic polarisabilities. The new polarisable force field, CL\&Pol, describes a broad set set of ionic liquids and their mixtures with molecular compounds, and is validated by comparisons with experimental data on density, ion diffusion coefficients and viscosity. The approaches proposed here can also be applied to the conversion of other fixed-charged force fields into polarisable versions.
Steady-State Kinetics of the Autocatalytic Zymogen Activation: A Comparison with the Michaelis-Menten Reaction Mechanism
Authors: Tyczynska Malgorzata , Eilertsen Justin , Schnell Santiago
Published: July 2019

A zymogen is an inactive precursor of an enzyme, which needs to go through a chemical change to become an active enzyme. The general intermolecular mechanism for the autocatalytic activation of zymogens is governed by the single-enzyme, single-substrate catalyzed reaction following the Michaelis-Menten mechanism of enzyme action, where the substrate is the zymogen and product is the same enzyme catalyzing the reaction. In this article we investigate the nonlinear chemical dynamics of the intermolecular autocatalytic zymogen activation reaction mechanism, and compare it to that of the Michaelis-Menten reaction mechanism. We show that the intermolecular autocatalytic zymogen activation exhibits significant changes in reaction dynamics relative to the Michaelis-Menten reaction mechanism. These changes include differences in the number of conservation laws, number and stability of equilibrium states, altered structure of the invariant set that influences the long-time rate of the reaction, and qualitative evolution of the reaction depending strictly on the choice of initial conditions. We find a rate law, homologous to the Michaelis-Menten equation, to estimate the kinetic parameters of the intermolecular autocatalytic zymogen activation reaction mechanism, and derive the conditions for the validity for this rate law. Finally, we derive analytical expressions to estimate the timescale for the completion of the zymogen activation, which could have a practical application to calculate the molar enthalpy of the autocatalytic zymogen reaction in calorimetry assays.
