Abstract

Background
Fish oil contains polyunsaturated fatty acids including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) which were considered as essential fatty acids. The purpose of present study was to evaluate the effects of fish oil supplementation on maternal serum fasting blood sugar (FBS), oral glucose tolerance test (OGTT), hemoglobin (Hb), and hematocrit (Hct).

Methods
In this randomized triple-blind clinical trial, 150 pregnant women were allocated into two groups randomly. In the intervention group, women received one fish oil capsule daily (1,000 mg consisted of 120 mg DHA and 180 mg EPA), and control group received placebo from the end of twentieth week of pregnancy until delivery (140 capsules). FBS, 2-hour 75 g OGTT, Hb, and Hct were measured at 6–10 and 26–30 weeks of pregnancy. Analysis was based on intervention to treat.

Results
At the weeks 26–30, mean FBS in the intervention and control groups were 76.92 (9.8) and 75.64 (8.2) mg/dl, respectively [adjusted mean difference (aMD) (95% CI):1.46 (−2.13 to 5.05)]. Also, there was no significant difference between two groups in 2-hour OGTT [aMD (95% CI): −4.69 (−13.75 to 4.52)]. Mean (SD) Hb was 11.8 (1.1) versus 11.8 (0.7) g/dl in the intervention and control groups, respectively [aMD (95% CI): 0.001 (−0.328 to 0.330)], mean (SD) Hct were 36.12% (2.8%) and 35.84% (2.3%), respectively [aMD (95% CI): 0.25 (−0.65 to 1.14)].

Conclusions
Based on the findings of present study, fish oil supplementation has no significant effect on Hb, Hct, FBS and 2-hour OGTT of pregnant women.
A review on mechanical and water absorption properties of polyvinyl alcohol based composites/films
Authors: Jain Naman , Singh Vinay Kumar , Chauhan Sakshi 
Published: February 2018

AbstractPolyvinyl alcohol (PVA) is a nontoxic and thermoplastic polymer which is completely biodegradable. PVA shows excellent mechanical and thermal properties due to better interfacial adhesion with reinforcing material such as fibers, particles or flakes because of which it can be used for fabrication of composite. PVA based fiber or particle reinforcing composites have gained interest in many applications in different fields. This paper reviews the mechanical and water absorption properties studied by different researcher and some of them were discussed here. The article also focused on the effect on the mechanical properties on PVA based composites with particle or fiber used as reinforcing material at nano/micro level and different polymers used to prepare PVA blend films. The major disadvantage of PVA based composites/films is higher water uptake or solubility in water. To over this negative aspect, many researchers studied crosslinking of PVA based composites/films, which are also discussed in the article. This review concludes that PVA has the potential for use in the synthesis of composites/films with their abundant applications.
The adventure of the deceitful numbers
Authors: Andrade-Molina Melissa 
Published: February 2018

AbstractThis article addresses access to high-quality education under a neoliberal mentality. It engages at both the discursive and material levels, by mapping how taken-for-granted truths about neoliberal policies circulate through the media. The media—newspapers, network channels, and news websites—have correlated quality education with socioeconomic status, which have effects of power in the fabrication of the productive citizen and low-performer, and in the perpetuation of the “class/room”.The unexpected deceitfulness of numbers operates as a rhizomatic regime of truths, conducting our ways of being and acting in the world. This analysis takes numbers as an actor to challenge the apparent representative and descriptive nature of standardized assessment outcomes, and the idea that competition, freedom of choice, and accountability are a means of securing equity, inclusion, and economic growth. The novels of Sir Arthur Conan Doyle, particularly those featuring the fictional character Sherlock Holmes, and the Sherlock Holmes adaptations portrayed by Benedict Cumberbatch in the TV series “Sherlock” have inspired the narrative of this story. Sherlock’s mind palace—a feature added to Holmes’ personality in the TV series—is put to great use in the narrative of this article.

Primary pleomorphic liposarcoma of fallopian tube with recurrence: a case report and review of the literature
Authors: Wang Lianwei , Luo Runlan , ZumingXiong  , Xu Jinming , Fang Dengyang 
Published: February 2018

Abstract

Background
Liposarcoma, which develops in adipose tissue, is one of the most common soft tissue sarcomas. It appears mostly in the lower limbs, particularly in the thigh and limb girdles, followed by the upper extremities, thoracoabdominal wall, and the internal trunk and retroperitoneum. Pleomorphic liposarcoma (PLS), a rare subtype of liposarcoma is considered a highgrade malignancy.

Case presentation
We present a case of primary PLS in the left fallopian tube of a 47-year-old female. Ten months previously, she was diagnosed with PLS of the left fallopian tube in another hospital and had a wide excision of left fallopian tube mass, including total abdominal hysterectomy and bilateral salpingo-oophorectomy for left fallopian tube PLS. Presently, she has developed a recurrence and metastasis of PLS in the pelvic and abdominal cavities.

Conclusion
This may be the first case of primary fallopian tube PLS, wherein the prognosis of this patient was poor due to the high-grade malignancy of PLS.

Application of ANNs approach for wave-like and heat-like equations
Authors: Jafarian Ahmad , Baleanu Dumitru 
Published: February 2018

AbstractArtificial neural networks are data processing systems which originate from human brain tissue studies. The remarkable abilities of these networks help us to derive desired results from complicated raw data. In this study, we intend to duplicate an efficient iterative method to the numerical solution of two famous partial differential equations, namely the wave-like and heat-like problems. It should be noted that many physical phenomena such as coupling currents in a flat multi-strand two-layer super conducting cable, non-homogeneous elastic waves in soils and earthquake stresses, are described by initial-boundary value wave and heat partial differential equations with variable coefficients. To the numerical solution of these equations, a combination of the power series method and artificial neural networks approach, is used to seek an appropriate bivariate polynomial solution of the mentioned initial-boundary value problem. Finally, several computer simulations confirmed the theoretical results and demonstrating applicability of the method.

Authors: Saygin Ali , Kerem Alper 
Published: February 2018

Abstract
This paper presents speed control analysis of an induction motor by a 6-switched 3-level inverter. In the analysis of topology, the study used the field oriented control technique which is widely used in the literature, easy and stable for operating systems. The field weaking technique was used for speeds exceeding nominal speed to reduce magnetic saturation and thermal losses. At the end of the process, it was observed to increase motor torque and inverter efficiency. Instead of using 12 switches in conventional 3-level inverters, 6 switches are used in this topology. Reduced number of switches is the greatest contribution of this study.
Analysis of the process influences on injection molded thermosets filled with hollow glass bubbles
Authors: Hopmann Christian , Theunissen Matthias , Haase Stefan 
Published: February 2018

Abstract
Thermoset molding compounds have a wide range of beneficial properties such as easy handling, high temperature, chemical resistance, low shrinkage as well as low electrical conductivity. However, these properties come at the cost of a higher density than technical thermoplastic materials and thus the potential for lightweight applications is reduced. Due to the low viscosity of the resin within thermoset molding compounds a wide variety of filler materials can be used. The addition of low density hollow glass bubbles as a filler material in thermoset molding compounds offers the opportunity to decrease the density of the molding compound. At the same time the stiffness of the micro glass bubbles is expected to increase the stiffness of the material. In the present study, a thermoset molding compound was filled with different quantities of hollow glass bubbles and the effects of the filler content as well as the processing parameters were investigated regarding their effect on the weight and mechanical properties of the parts. Based on the results, significant weight reductions up to 5% were achieved. Furthermore, a significant impact of the process parameters on weight reductions was found. The results indicate that higher shearing reduces the weight. This can also contribute to damaging of the glass bubbles during the injection molding process. Similar results were found regarding the effect of process parameters on the mechanical properties.
Hydrogenation of carbonyl compounds of relevance to hydrogen storage in alcohols
Authors: Suárez Andrés 
Published: February 2018

Abstract
Alcohols are a promising source for the sustainable production of hydrogen that may also serve as rechargeable liquid organic hydrogen carriers (LOHCs). Metal-catalyzed acceptorless dehydrogenation of alcohols produces carbonyl derivatives as H2-depleted by-products, which by means of a hydrogenation reaction can be reconverted to the initial alcohols. Hence, reversible H2-storage systems based on pairs of secondary alcohols/ketones and primary alcohols/carboxylic acid derivatives may be envisaged. In this contribution, the hydrogenation of carbonyl derivatives, including ketones, esters, amides and carboxylic acids, is reviewed from the perspective of the hydrogen storage in alcohols.

Abstract
Vigotsky, AD, Bryanton, MA, Nuckols, G, Beardsley, C, Contreras, B, Evans, J, and Schoenfeld, BJ. Biomechanical, anthropometric, and psychological determinants of barbell back squat strength. J Strength Cond Res 33(7S): S26–S35, 2019—Previous investigations of strength have only focused on biomechanical or psychological determinants, while ignoring the potential interplay and relative contributions of these variables. The purpose of this study was to investigate the relative contributions of biomechanical, anthropometric, and psychological variables to the prediction of maximum parallel barbell back squat strength. Twenty-one college-aged participants (male = 14; female = 7; age = 23 ± 3 years) reported to the laboratory for 2 visits. The first visit consisted of anthropometric, psychometric, and parallel barbell back squat 1 repetition maximum (1RM) testing. On the second visit, participants performed isometric dynamometry testing for the knee, hip, and spinal extensors in a sticking point position-specific manner. Multiple linear regression and correlations were used to investigate the combined and individual relationships between biomechanical, anthropometric, and psychological variables and squat 1RM. Multiple regression revealed only 1 statistically predictive determinant: fat-free mass normalized to height (standardized estimate ± SE = 0.6 ± 0.3; t(16) = 2.28; p = 0.037). Correlation coefficients for individual variables and squat 1RM ranged from r = −0.79 to 0.83, with biomechanical, anthropometric, experiential, and sex predictors showing the strongest relationships, and psychological variables displaying the weakest relationships. These data suggest that back squat strength in a heterogeneous population is multifactorial and more related to physical rather than psychological variables.

Abstract
Nikolaidis, PT and Knechtle, B. Performance in 100-km ultramarathoners—At which age, it reaches its peak? J Strength Cond Res 34(5): 1409–1415, 2020—The number of those participating in 100-km ultramarathon has increased over the past years; however, we have limited knowledge about performance trends in this sport, and particularly, the effect of age. The aim of this study was to analyze the age when women and men runners achieve their peak performance considering 1- and 5-year age group intervals, and examining all or the fastest (i.e., top 10) participants in each age group. We analyzed 370,051 athletes (i.e., 44,601 women and 325,450 men) who finished a 100-km ultramarathon between 1959 and 2016, and studied the age of peak performance using a second-order nonlinear regression analysis. The age of peak performance was 40–44 years in women and 45–49 years in men when all finishers were analyzed, whereas it was 30–34 years in women and 35–39 years in men when the top 10 finishers were considered in 5-year age groups. When we analyzed finishers in 1-year age groups, we found the age of peak performance at 41 years in women and 45 years in men considering all finishers, and at 39 years in women and 41 years in men considering the top 10 finishers. In conclusion, the age of peak performance was younger in women than in men, which might reflect the overall younger age of women participants than men. Compared with previous studies, we observed the peak performance at an age older by ∼10 years, which could be attributed to an increase of finishers' age across calendar years. Because the knowledge of the age of peak performance is unique for each sport, coaches and fitness trainers might benefit from the findings of this study in the long-term training of their athletes.

Abstract
Boucher, BK, Rich, AJ, Gobert, D, Gardner, B, Metzner, P, King, C, and Buse, M. The effectiveness of a functional movement assessment and 4-week exercise training program for female high school athletes. J Strength Cond Res 35(1): 102–110, 2021—The extent to which young females participate in school-sponsored athletics has grown significantly over the past 2 decades. The number of females in high school sports increased for the 25th consecutive year in 2012–2013, reaching an all-time record. Unfortunately, sports-related injury rates for female athletes have also continued to rise. A body of research exists to suggest that dysfunctional movement may be linked to increased risk of injury, and training programs designed to improve movement patterns are effective to both enhance performance and reduce the risk of injury. Effective training programs incorporate corrective exercises to retrain dysfunctional movement patterns. The Functional Movement ScreenTM (FMSTM) is a tool developed to assess 7 fundamental movement patterns. The FMSTM has been used extensively with a wide range of athletes at various levels of performance. The aim of this study was to investigate the effectiveness of a movement-training program with female high school athletes using the FMSTM. The overall purpose was to assess the effectiveness of a 4-week corrective exercise-training program at improving FMSTM scores. Data analysis using Wilcoxon signed-rank test revealed a statistically significant change in total group FMSTM scores (Z = −2.214, p = 0.027) after the corrective exercise-training program. Mean total group FMSTM scores increased from 14.43 ± 1.90 (pretest) to 17.29 ± 1.38 (posttest). Findings suggest that positive outcomes to a corrective exercise-training program, which targets specific movement impairments, can be achieved in a relatively short period of time.

Abstract
Byrd, MT, Wallace, BJ, Clasey, JL, and Bergstrom, HC. Contributions of lower-body strength parameters to critical power and anaerobic work capacity. J Strength Cond Res 35(1): 97–101, 2021—This study examined the contribution of lower-body strength and isokinetic peak torque measures to the prediction of critical power (CP) and anaerobic work capacity (AWC). Fourteen recreationally trained males (mean ± SD age: 22.4 ± 2.5 years; height: 177.9 ± 7.7 cm; body mass: 84.2 ± 12.4 kg) with anaerobic training experience participated in this study. The lower-body strength measures included 1 repetition max bilateral back squat (BSq), isokinetic peak torque at 30°·s−1 [PT30], and isokinetic peak torque at 240°·s−1 [PT240] of the dominant leg. The CP and AWC were determined from the 3-minute all-out CP cycle ergometer test (CP3MT), with the resistance set at 4.5% of the total body mass. The CP was defined as the mean power output over the final 30 seconds of the test, and the AWC was calculated using the equation, AWC = 150 seconds (P150 − CP), where P150 equals the mean power output for the first 150 seconds. Stepwise regression analyses indicated that only BSq contributed significantly to the prediction of AWC (AWC = 0.0527 [BSq] + 8.094 [standard error of estimate = 2.151 kJ; p = 0.012]), with a correlation of r
2 = 0.423. None of the strength parameters significantly predicted CP. These findings indicated that BSq strength accounted for 42% of the variance in AWC, but lower-body strength was not related to CP. The current results indirectly support the unique metabolic characteristics of both CP and AWC in providing separate measures of an individual's aerobic and anaerobic capabilities, respectively.

Abstract
Mock, MG, Hirsch, KR, Blue, MNM, Trexler, ET, Roelofs, EJ, and Smith-Ryan, AE. Postexercise ingestion of low or high molecular weight glucose polymer solution does not improve cycle performance in female athletes. J Strength Cond Res 35(1): 124–131, 2021—The current study sought to evaluate the effects of postexercise ingestion of a high molecular weight (HMW) glucose polymer solution compared with an isocaloric low molecular weight (LMW) solution or placebo (PLA) on subsequent cycling performance in female athletes. In a randomized, double-blind, placebo-controlled, cross-over design, 10 competitive female cyclists (Mean ± SD; Age = 25.7 ± 5.0 years; V̇o
2peak = 49.7 ± 4.3 ml·kg−1·min−1) completed 3 testing sessions separated by 7–10 days. Visits consisted of a ride-to-exhaustion (RTE) at 75% V̇o
2peak, followed by immediate consumption of 700 ml containing either: 1.2 g·kg−1 LMW (maltodextrin/dextrose/fructose); 1.2 g·kg−1 HMW (Vitargo); or 0.066 g·kg−1 PLA (noncaloric flavoring). After 2 hours of rest, subjects performed a 15-minute time trial (TT). Respiratory exchange ratio (RER) was assessed via indirect calorimetry during exercise. Total body water (TBW) was measured using bioelectrical impedance to assess fluid balance. When covaried for estrogen, there was no treatment effect on distance (km; p = 0.632) or power output (watts; p = 0.974) during the 15-minute TT. Respiratory exchange ratio was not significantly different during the LMW and HWM TTs (p > 0.999), but both were significantly higher than PLA (p = 0.039, p = 0.001, respectively). Changes in total body water pre-exercise to postexercise were not significantly different between trials (p = 0.777). Despite benefits of HMW on cycling performance previously reported in males, current results demonstrate no ergogenic effect of HMW or LMW in females. Sex differences in substrate utilization may account for the discrepancy, and further research involving performance nutrition for female athletes is merited.

Published: February 2018

Abstract
In the study presented herein, a simple method for laboratory calcite cementation of a reconstituted gravelly sand was presented. This method was used to prepare cemented gravelly sand specimens, which have similar natural characteristics to alluvial deposit of the city of Tehran. The formation and distribution of calcite bonds, as well as the effectiveness of the presented calcite cementation method in increasing interparticle cohesion, as observed in weakly to moderately cemented soil in Tehran, were evaluated by means of chemical analysis, X-ray diffraction technique, and unconfined compressive strength tests. The cementation technique was used to prepare triaxial specimens with calcite contents ranging from 1.5 to 6 %. Then, a series of monotonic and cyclic undrained triaxial tests was performed to characterize the behavior of calcite-cemented gravelly sand with different calcite contents under different loading conditions. In comparison with the specimens with zero calcite content, the cemented specimens exhibited a distinctly different behavior in terms of static stiffness and strength, cyclic pore pressure generation, and cyclic strength. Results of the monotonic triaxial tests indicated an increased shear strength with an increase in calcite content and confining pressure in the tested soil. Because of the presence of interparticle cohesion, cemented soils behaved less compressive during cyclic loading, and accordingly, the rate of positive pore pressure generation in these specimens was lower during loading with smaller induced plastic deformations.
