Abstract
Coetzee, B, and Malan, D. Laboratory-based physical and physiological test results that serve as predictors of male, amateur road cyclists' performance levels. J Strength Cond Res 32(10): 2897–2906, 2018—The purposes of this study were first, to determine the practical significant differences of laboratory-based physical and physiological test results between a selected group of successful and less successful amateur, male road cyclists from Africa; and second, to determine the significance, adequacy, accurateness, and usefulness of laboratory-based physical and physiological test results to serve as predictors of these amateur, male road cyclists' performance levels. Male road cyclists, identified as the top amateur road cyclists of the cycling federations of 13 African countries, were subjected to a test battery for the measurement of lower-body flexibility, abdominal strength, peak and average anaerobic power output as well as maximum aerobic power. Practical significant differences between the successful and less successful road cyclists were found for almost all the Wingate related variables, some of the sub-maximum parameters, and most of the maximum physiological variables. Finally, the abdominal muscle strength test value, vertical jump distance, Wingate relative peak power, and respiratory compensation point expressed as percentage of V̇o
2max and as relative power output were the physiological components that acted as adequate, accurate, and useful predictors of performance levels. Coaches and sport scientists should therefore include these components in testing protocols that are aimed at evaluating and improving cyclists' physical conditioning programs.

Abstract
Caterisano, A, Hutchison, R, Parker, C, James, S, and Opskar, S. Improved functional power over a 5-week period: Comparison of combined weight training with flexible barbell training. J Strength Cond Res 32(8): 2109–2115, 2018—Previous studies demonstrated increased power development with various resistance-training modes over short training periods of 4–7 weeks through neuromuscular adaptations. The purpose of this study was to compare 2 different power-training regimens over a 5-week period: combined weight training program (CT) using speed-lifts and plyometrics vs. flexible barbell (FB) training. College football players (n = 28) were randomly assigned to either FB or CT training groups. The CT group followed a combined weight training program using 45–65% of 1 repetition maximum, and the FB group used an FB with a fixed mass of 56.82 kg for all lifts. Both groups performed similar lifts 4 days per week in a split routine, alternating muscle groups. Subjects were tested before and after the training period by the vertical jump (VJ), long jump, medicine ball (MB) throw, and Margaria-Kalamen stair power test. Pre- to post-tests, both groups experienced significant increases in VJ (CT: 57.9 ± 8.9 to 64.5 ± 7.9 cm, FB: 68.1 ± 6.9 to 74.9 ± 6.6 cm) and MB (CT: 513.3 ± 69.3 to 594.9 ± 78.2 cm, FB: 510.0 ± 41.4 to 613.9 ± 52.6 cm) that were not significantly different between training modes. Long jump improved significantly only in FB (248.4 ± 23.1 to 254.3 ± 24.6 cm) and not in CT. The Margaria-Kalamen stair power test result improved in both groups but FB improved at a significantly higher level than CT (CT: 40.6 ± 2.3 to 44.3 ± 2.2 W, FB: 41.0 ± 1.7 to 48.8 ± 1.8 W). The results suggest that both FB and CT training improved power over a 5-week training period, but that FB training may be more effective than CT in lower-body power development.

Abstract
Comfort, P, Dos'Santos, T, Thomas, C, McMahon, JJ, and Suchomel, TJ. An investigation into the effects of excluding the catch phase of the power clean on force-time characteristics during isometric and dynamic tasks: an intervention study. J Strength Cond Res 32(8): 2116–2129, 2018—The aims of this study were to compare the effects of the exclusion or inclusion of the catch phase during power clean (PC) derivatives on force-time characteristics during isometric and dynamic tasks, after two 4-week mesocycles of resistance training. Two strength matched groups completed the twice-weekly training sessions either including the catch phase of the PC derivatives (Catch group: n = 16; age 19.3 ± 2.1 years; height 1.79 ± 0.08 m; body mass 71.14 ± 11.79 kg; PC 1 repetition maximum [1RM] 0.93 ± 0.15 kg·kg−1) or excluding the catch phase (Pull group: n = 18; age 19.8 ± 2.5 years; height 1.73 ± 0.10 m; body mass 66.43 ± 10.13 kg; PC 1RM 0.91 ± 0.18 kg·kg−1). The Catch and Pull groups both demonstrated significant (p ≤ 0.007, power ≥0.834) and meaningful improvements in countermovement jump height (10.8 ± 12.3%, 5.2 ± 9.2%), isometric mid-thigh pull performance (force [F]100: 14.9 ± 17.2%, 15.5 ± 16.0%, F150: 16.0 ± 17.6%, 16.2 ± 18.4%, F200: 15.8 ± 17.6%, 17.9 ± 18.3%, F250: 10.0 ± 16.1%,10.9 ± 14.4%, peak force: 13.7 ± 18.7%, 9.7 ± 16.3%), and PC 1RM (9.5 ± 6.2%, 8.4 ± 6.1%), before and after intervention, respectively. In contrast to the hypotheses, there were no meaningful or significant differences in the percentage change for any variables between groups. This study clearly demonstrates that neither the inclusion nor exclusion of the catch phase of the PC derivatives results in any preferential adaptations over two 4-week, in-season strength and power, mesocycles.

Abstract
Williams, MR Jr, Hendricks, DS, Dannen, MJ, Arnold, AM, and Lawrence, MA. Activity of shoulder stabilizers and prime movers during an unstable overhead press. J Strength Cond Res 34(1): 73–78, 2020—Overhead reaching is a common movement that relies heavily on muscles for dynamic stability. Stabilizer muscle activation increased during squatting and bench pressing with an unstable load, but the overhead press (OHP) has yet to be examined. The purpose of this study is to compare muscle activity of the shoulder stabilizers and prime movers and excursions of the center of pressure (CoP) during the OHP in 2 unstable and one stable conditions. Twelve men (aged 25.3 ± 2.7 years, mass: 91.5 ± 8.4 kg, height: 1.81 ± 0.06 m) pressed 50% of their 1 repetition maximum for 10 repetitions over 3 conditions: a straight stable barbell (SS), a straight unstable (SU) barbell with kettlebells suspend by elastic bands, and an unstable Earthquake (EU) bar with kettlebells suspended by elastic bands. Activity of the shoulder stabilizers and prime movers were measured via surface and indwelling electromyography. Center of pressure excursion of the right foot was also measured. A multivariate analysis was used to determine significant differences between conditions. Pressing with the EQ increased activation of the biceps brachii, erector spinae, latissimus dorsi, pectoralis major, rectus abdominus, rhomboids, and serratus anterior over the SS condition, whereas only the SU condition increased activation in the erector spinae and latissimus dorsi muscles. The EQ condition produced greater CoP excursion (35.3 ± 7.9% foot length) compared with the SU (28.0 ± 7.2% foot length) and SS (22.2 ± 6.3% foot length) conditions. Therefore, the EU condition may be an effective exercise to activate scapular stabilizers.

Abstract
Botonis, PG, Toubekis, AG, and Platanou, TI. Physiological and tactical on-court demands of water polo. J Strength Cond Res 33(11): 3188–3199, 2019—The purpose of the present review is to provide a quantification of the specific game's activities performed by elite water polo players and a comprehensive overview of the physiological requirements reflecting physical and tactical on-court demands in water polo. Game analysis demonstrates that various swimming movements occur throughout a match play, although approximately 50% of these are recorded in horizontal body position. The various offensive and defensive tactical actions transiently modify the playing intensity, which overall corresponds to the players' lactate threshold. Even play corresponds to 60% of total game actions, whereas the respective percentage of power-play and counterattacks may exceed 30%. The ability to perform high-intensity activities with short recovery periods is critical for water polo players. Elite water polo players present a high level of aerobic power and endurance as indicated by their maximal oxygen uptake and speed at the lactate threshold. Depending on the positional roles, outfield players are characterized as centers or peripherals. The overall physiological load seems to be similar between players at various positions, despite that centers execute more dynamic body contacts, whereas peripherals more swimming bouts. Despite limitations concerning the experimental setting, the current findings indicate that the incidence of fatigue deteriorates playing intensity and performance. Nonetheless, data from the reviewed studies should be cautiously interpreted because in some of the studies, players' substitutions were not allowed. A high conditioning level is essential for water polo, as it is associated with superior technical and tactical efficacy and lower decline of physical or technical performance within the game.

Abstract
McGhie, D, Østerås, S, Ettema, G, Paulsen, G, and Sandbakk, Ø. Strength determinants of jump height in the jump throw movement in women handball players. J Strength Cond Res 34(10): 2937–2946, 2020—The purpose of the study was to improve the understanding of the strength demands of a handball-specific jump through examining the associations between jump height in a jump throw jump (JTJ) and measures of lower-body maximum strength and impulse in handball players. For comparison, whether the associations between jump height and strength differed between the JTJ and the customarily used countermovement jump (CMJ) was also examined. Twenty women handball players from a Norwegian top division club participated in the study. Jump height was measured in the JTJ and in unilateral and bilateral CMJ. Lower-body strength (maximum isometric force, one-repetition maximum [1RM], impulse at ∼60% and ∼35% 1RM) was measured in seated leg press. The associations between jump height and strength were assessed with correlation analyses and t-tests of dependent r's were performed to determine if correlations differed between jump tests. Only impulse at ∼35% 1RM correlated significantly with JTJ height (p < 0.05), whereas all strength measures correlated significantly with CMJ heights (p < 0.001). The associations between jump height and strength were significantly weaker in the JTJ than in both CMJ tests for all strength measures (p = 0.001–0.044) except one. Maximum strength and impulse at ∼60% 1RM did not seem to sufficiently capture the capabilities associated with JTJ height, highlighting the importance of employing tests targeting performance-relevant neuromuscular characteristics when assessing jump-related strength in handball players. Further, CMJ height seemed to represent a wider range of strength capabilities and care should be taken when using it as a proxy for handball-specific movements.

Published: June 2018

Abstract
The membrane-forming performance of emulsified wax curing agent (EWCA) and the mechanical properties of the ice layer atop the cement concrete surface were explored via a series of tests in the research of this article. First, the tests for the membrane-forming performance of EWCA atop the glass plates or the cement concrete test blocks were conducted; the thermal endurance of the formed EWCA membrane, its performance against water erosion, the observation of its appearance, and the microstructure were the primary areas of focus in the research. These tests were performed to determine an optimized formula for EWCA and a practical product of EWCA with high performance. This kind of EWCA product was used in the tests for the mechanical properties of the ice layer atop the cement concrete test blocks. The results of these tests indicated that the EWCA product sprayed on the cement concrete surface reduced the sheer bond stress between the ice layer and the cement surface by 62 %, reduced the pull-out bond stress of the ice layer by 38 %, and reduced the impact resistance of the ice layer by 60 %. Thus, it can be concluded that spraying EWCA atop the cement concrete surfaces might improve the efficiency of removing the ice layer from the cement concrete surface.
On the Intensification of Natural Gas-Based Hydrogen Production Utilizing Hybrid Energy Resources
Authors: Pichardo Patricia A. , Manousiouthakis Vasilios I. 
Published: June 2018

Abstract
In this work, parametric studies are carried out for natural gas-based hydrogen production systems utilizing hybrid energy sources, such as natural gas and concentrated solar power (CSP). The main technologies utilized in the considered networks consist of steam methane reforming, reverse water-gas shift, high-temperature shift, and low-temperature shift reactors; ideal hydrogen and carbon dioxide separators; water flash separators; pressure changing devices; and a heat exchange network (HEN). A broad search of the design space is carried out within the Infinite DimEnsionAl State-space conceptual framework, which allows for the simultaneous synthesis of the hydrogen production process and its associated HEN using linear programming. The identified designs minimize the total cost of three hot utilities and one cold utility, subject to bounding constraints on the work of separation and the HEN area. The level of exothermicity of the reforming operations, and the extent of CSP use, are shown to depend on the employed utility cost ratios and the aforementioned work and area bounds.

Analysis of teaching resources used in EFL classes in selected Ecuadorian universities
Authors: Acosta Hazel , Cajas Diego 
Published: June 2018

This study looks at how Communicative Language Teaching (CLT) is implemented in Ecuadorian universities through analysis of teaching resources that teachers use in classes. A survey was conducted through the administration of a questionnaire. A total of 65 teachers responded to the survey. The results indicated that in developing productive skills, group-oriented activities such as pair-and-share scheme and role-plays are frequently conducted, and the use of worksheets, translator applications and audio materials were often used in developing students’ receptive skills. Teachers did not often use resources on pronunciation activities, direction-oriented tasks and translation using Spanish. Analysis of frequently used resources showed that teachers tried to develop students’ communicative competence, one of the core principles of CLT, however, most of these resources were not teacher-made but support materials of textbooks produced by publishing houses abroad. Too much dependence on these resources influences teacher interaction with students and also diminishes the role of the teacher as the frontline source of language use especially in listening and speaking when audio materials and worksheets replace the teachers’ voice. Indeed, the selection of a teaching resource is as crucial as the method employed in CLT implementation in EFL classroom.
COMPARISON OF 14C-UREA BREATH TEST WITH GASTRIC HISTOLOGY FOR DIAGNOSIS OF HELICOBACTER PYLORI INFECTION AMONG PATIENTS WITH PEPTIC ULCER DISEASE
Authors: Alkarboly Taha , Husein Hiwa , Faraj Heero 
Published: June 2018

Background
Helicobacter pylori infection is common among patients with peptic ulcer disease. The definitive means of diagnosing infection being histology requires endoscopy and sedation making it invasive and expensive. The carbon urea breath test is generally considered to be a simple, non-invasive and accurate test for the detection of Helicobacter pylori infection both before and after treatment.
Objectives
Our objective was to compare histology with a less invasive and safer method, the 14C-urea breath test.
Materials and Methods
After approval of Ethical committee of the Iraqi Board for Medical Specialties, informed consent were taken from every patient before esophagogastroduodenoscopy. Fifty patients with peptic ulcer disease diagnosed by endoscopy were evaluated by 14C-urea breath test. Four biopsies were taken for histology. After endoscopy, each patient was evaluated by both tests for diagnosis of Helicobacter pylori infection
Results
50 patients with peptic ulcer disease Helicobacter pylori infection was diagnosed in 35 patients (63.45%), while in 15 patients (36.55%) were negative for Helicobacter pylori infection using gastric histology and urea breath test. Compared with histology, the diagnostic values of the 14C-urea breath test were: sensitivity 94%, specificity 87%, positive predictive value 94%, and negative predictive value 87%.
Conclusion
The 14C-urea breath test is a noninvasive diagnostic tool for Helicobacter pylori infection. It’s a sensitive and specific test with excellent positive predictive value and its good negative predictive value guarantee its usefulness in clinical practice.
LAPAROSTOMY USING URINE BAGS AS A CONTAINER, CASE SERIES STUDY IN SULAIMANI EMERGENCY AND SULAIMANI TEACHING
Authors: Arif Sarmad 
Published: June 2018

Background
Laparotomy wound is usually closed at the end of the operation. However, in certain occasions, it is undesirable, difficult or even imapossible to do so. The abdomen may be left open for a while; a situation called (contained laparostomy).
Objectives
The aim of this paper is to describe a simple and cheap method of temporary abdominal closure.
Patients and Methods
Over a 7-year period (2008-2015), 11 patients underwent emergency laparotomy for trauma, abdominal sepsis or intra-abdominal compartment syndrome in Sulaimani, Iraq, after which the abdomen was temporarily, closed using a sterile urine bag. Daily change of dressing and irrigation of the wound with saline was performed until the time of definite closure of skin and fascia.
Results
There were nine males (82%). Age ranged from 21 to 72 years with a mean of 43±15 year. Six patients (55%) had penetrating trauma, 4 (36.4%) had abdominal sepsis and one (9.1%) had abdominal compartment syndrome. The urine bag was kept for 7 days in 8 patients (72%), 12 days in 2 patients (18.2%) and 32 days in one patient (9.1%). Two patients (18.2%) had disruption of bag to skin sutures and another two (18.2%) had superficial wound infection. Two patients (18.2%) died due to multiple organ failure and pulmonary embolism.
Conclusion
Laparostomy management using a urine bag is cheap, simple, effective and easy to perform with minimal morbidity.
