Abstract
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

Abstract
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

Abstract
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.

Abstract

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.

Abstract
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.

Published: July 2019

Abstract

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

Abstract
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

Abstract
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

Abstract
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.

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.

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.
