Authors: Sutkowska Edyta , Konieczny Grzegorz , Wrzosek Zdzisława , Sutkowski Krzysztof 
Published: July 2016

AbstractObesity is an independent risk factor for a number of diseases. Inadequate weight makes post-operative rehabilitation more difficult. It is not uncommon that at the post-operative stage many abnormalities, often ignored by the patient, are discovered. For this reason, the recovery takes longer and its results are not always satisfactory for patients and physicians. Adequate preparation of obese patients for the procedure and awareness of potential difficulties that may arise during post-operative rehabilitation are essential requisites for effective cooperation with the patient and safe recovery. The paper describes the most frequent problems experienced by obese patients during rehabilitation.

Published: July 2016

AbstractAim of the study. The aim of this study The aim of this study was to assess the impact of the six-week therapeutic exercise program on the risk of falls in women with type II diabetes.Material and methods. The study included 15 women suffering from type II diabetes for more than 10 years. The patients have participated in a six-week non-public physiotherapy programme in the Private Outpatient Therapeutic and Rehabilitation Clinic “ZDROWIE” in Oława. To assess the risk of falls, we used the short form of The Falls Risk Assessment System.All participants were subjected to two series of measurements, before and after treatment, during which we examined the rate of falls by five functional tests. In addition, women have evaluated their own subjective assessment of the balance by means of a numerical ten-point visual analogue scale.Results. The therapeutic exercise programme used contributed significantly to reducing the rate of falls (with Z-score =1.14 on the Z-score = 0.09) by improving the performance of quadriceps muscle strength, balance, reaction time and proprioception. There was also an increase in the subjective assessment of self-sustainability.Conclusions. Regular exercise aimed at improving sensorimotor function reduces the impact of falls risk in women with type II diabetes. Physical activity has a positive effect on the stability of posture.
Children’s perception of human body
Authors: Nitecka-Walerych Anna 
Published: July 2016

AbstractThe subject of this article is the perception of the modern human body by young people, more specifically pupils of primary school. I based my research on the assumption that the human body, like the entire human being, is the result of a certain stage in the evolutionary process and it is entangled in social relationships. One may define it as nature functioning within culture. Throughout the centuries, various assets of the human body have been held in high esteem, according to the demands of the natural world and social norms imposed in a given society, arising out of the aesthetic canon. But the closer we get to the modern times, the less important is the value of the natural factor, and the more important is the cultural creation. The aim of my research was to answer the following questions: How do ten-year-olds perceive the modern human body of a woman and of a man, how do they describe it, what features do they pay attention to and in what order, and additionally, does this image correspond to the image of “ideal” body pursued by post-modern society and promoted in the mass media. The research encompassed 124 pupils.

Published: July 2016

Abstract
Amino-functionalized Fe3O4@SiO2 nanoparticles (Fe3O4@SiO2–NH2 NPs) were prepared by treating Fe3O4@SiO2 NPs with (3-aminopropyl)-triethoxysilane. They have been characterized by powder X-ray diffraction, vibrating sample magnetometer, scanning electronic microscopy, energy dispersive X-ray, thermogravimetric analysis and FT-IR spectroscopy. A neat, atom-economical, environmentally benign one-pot multicomponent synthetic route for the synthesis of furo[3,2-c]coumarins in good yields has been devised using the Fe3O4@SiO2–NH2 NPs. The present methodology can be used for the design of libraries and diversity-oriented synthesis, and has potential for biological applications and drug discovery.

Abstract
Ramírez-Vélez, R, Correa-Bautista, JE, Lobelo, F, Cadore, EL, Alonso-Martinez, AM, and Izquierdo, M. Vertical jump and leg power normative data for Colombian schoolchildren aged 9–17.9 years: the FUPRECOL study. J Strength Cond Res 31(4): 990–998, 2017—The aims of the present study were to generate normative vertical jump height and predicted peak power (Ppeak) data for 9- to 17.9-year-olds and to investigate between-sex and age group differences in these measures. This was a cross-sectional study of 7,614 healthy schoolchildren (boys n = 3,258 and girls n = 4,356, mean [SD] age 12.8 [2.3] years). Each participant performed 2 countermovement jumps; jump height was calculated using a Takei 5414 Jump-DF Digital Vertical (Takei Scientific Instruments Co., Ltd.). The highest jump was used for analysis and in the calculation of predicted Ppeak. Centile smoothed curves, percentiles, and tables for the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles were calculated using Cole's LMS (L [curve Box-Cox], M [curve median], and S [curve coefficient of variation]) method. The 2-way analysis of variance tests showed that maximum jump height (in centimeters) and predicted Ppeak (in watts) were higher in boys than in girls (p < 0.01). Post hoc analyses within sexes showed yearly increases in jump height and Ppeak in all ages. In boys, the maximum jump height and predicted Ppeak 50th percentile ranged from 24.0 to 38.0 cm and from 845.5 to 3061.6 W, respectively. In girls, the 50th percentile for jump height ranged from 22.3 to 27.0 cm, and the predicted Ppeak was 710.1–2036.4 W. For girls, jump height increased yearly from 9 to 17.9 years old. Our results provide, for the first time, sex- and age-specific vertical jump height and predicted Ppeak reference standards for Colombian schoolchildren aged 9–17.9 years.

Abstract
Brandt, R, Bevilacqua, GG, and Andrade, A. Perceived sleep quality, mood states, and their relationship with performance among Brazilian elite athletes during a competitive period. J Strength Cond Res 31(4): 1033–1039, 2017—We described the perceived sleep quality and mood states of elite athletes during a competitive period, and clarified their relationship to athletes' sport performance. Participants were 576 Brazilian elite athletes (404 men and 172 women) of individual and team sports. Mood states were evaluated using the Brunel Mood Scale, whereas perceived sleep quality was evaluated using a single question (“How would you evaluate the quality of your sleep in the last few days?”). Evaluations of mood state and sleep quality were performed up to 60 minutes before national and international sports competitions began. Descriptive and inferential statistics (including logistic regression) were used to evaluate the relationship of sleep quality and mood states with performance (i.e., winning or losing). Athletes typically had good sleep quality and mood states similar to the Iceberg profile (i.e., high vigor and low tension, depression, anger, fatigue, and mental confusion). The Wald test revealed that sleep, anger, tension, and vigor predicted athletes' performance. Specifically, poor sleep quality and low vigor and anger decreased the odds of winning, whereas higher tension increased these odds. The Hosmer–Lemeshow test indicated that the results were sufficiently generalizable. Overall, we observed a significant relationship between sleep and mood states, which in turn both significantly influenced athletes' sports performance. Thus, coaching staff and athletes should monitor athletes' sleep quality before competitions to ensure athletes are in the optimal condition for performance.

<p>El territorio que une las dos metrópolis de Buenos Aires y Rosario está sometido a fuertes procesos metropolitanos, que nunca se han estudiado con precisión. Uno de estos procesos es la actividad productiva, cuyos dos actores principales son los grandes establecimientos industriales y las terminales portuarias. Su coexistencia en un espacio de metropolización precoz da lugar a un modelo original: un territorio a la vez fordista y post-fordista, que cuestiona la figura de la postmetrópolis propuesta por la Escuela de Los Ángeles.</p>
Peer- and self-assessment: A Case Study to Improve the Students’ Learning Ability
Authors: Li Ying , Chen Liping 
Published: July 2016

Current assessment practices in college English in China do not develop students’ abilities to reflect on their own learning. Peer- and self- assessment, the self-reflection phrase, can be seen as a means to tackle this problem. The purpose of the study was to explore the potential to take Peer and self-assessment as an effective method to change the way of students’ learning. An analysis of 60 students from Lanzhou University of Finance and Economics showed that peer and self- assessment can change the way the students’ learning. These two forms of assessment are often used in combination with each other. Implementation of these forms of assessment can involve the development of a learning teaching environment and shift the students’ learning methods from surface approaches to learning to deep approaches to learning gradually.

Published: July 2016

Background.Shoulder joint injuries and shoulder instability often occur in adolescents.Materials and methods. During a 3-year period, we performed arthroscopic surgery on 42 patients with shoulder joint injuries.Results and discussion. The majority (76.2%) of the patients on whom we performed arthroscopic shoulder joint surgery were male. This is likely due to more aggressive physical activity among males. Most of the patients were injured during exercise (n = 27, 64.3%). Arthroscopy is a highly effective surgical method for the treatment of shoulder joint injuries. Prolonged non-operative treatment with no well-established indications and an incorrect diagnosis can lead to rapid progression of degenerative and dystrophic changes of the shoulder joint and may result in shoulder joint dysfunction.

Published: July 2016

Background. Transposition of the acetabulum after pelvic osteotomy is the most effective surgical method to treat dysplastic hip joint disorders in patients of different ages. According to Salter, iliac osteotomy of the pelvis is the main surgical method used to correct dysplastic acetabulum in 7- and 8-year-old children. In older patients, the pubic symphysis and pelvic ligaments become more rigid, which significantly limits the degree of rotation of the acetabulum. In these cases, a triple pelvic osteotomy is performed to enhance the mobility of the acetabular fragment. This pubic bone osteotomy is performed near the femoral neurovascular bundle, which may be damaged during the procedure.Aim. To describe a technique for transposition of the acetabulum after iliac and ischial osteotomy of the pelvis, which was developed to reduce trauma, prevent vascular complications, and increase postoperative stability of the pelvic ring.Materials and methods. A method developed by the authors for transposition of the acetabulum after iliac and sciatic pelvic osteotomy is described in detail. The surgical method was performed 99 times on 89 children with dysplastic hip joint disorders, and the results are presented.Conclusion. Transposition of the acetabulum after iliac and ischial pelvic osteotomy is an effective treatment for dysplastic instability of the acetabulum in children aged 9–16 years. The procedure is indicated when it is necessary to rotate the acetabular fragment by more than 25°, and there is no need for hip medialization.

Published: July 2016

➢ Osteolysis is a process mounted by the host immune system that relies on several variables, including patient-related factors, type of insert material, modes of wear, and implant design.➢ Imaging techniques such as radiography, computed tomography (CT) scans, magnetic resonance imaging (MRI), and tomosynthesis aid in diagnosing osteolysis.➢ Surgical options for the treatment of osteolysis include the insertion of bone grafts, bone cement, and prosthetic augmentation.➢ Although no approved pharmacological therapies for the specific treatment of osteolysis exist, the use of bisphosphonates and statins decreases the risk of osteolysis.
The Use of a pH-Triggered Polymer Gelant to Seal Cement Fractures in Wells

Summary
The potential leakage of hydrocarbon fluids or carbon dioxide (CO2) out of subsurface formations through wells with fractured cement or debonded microannuli is a primary concern in oil-and-gas production and CO2 storage. The presence of fractures in a cement annulus with apertures on the order of 10–300 µm can pose a significant leakage danger with effective permeability in the range of 0.1–1.0 md. Leakage pathways with small apertures are often difficult for conventional oilfield cement to repair; thus, a low-viscosity sealant that can be placed into these fractures easily while providing a long-term robust seal is desired. The development of a novel application with pH-triggered polymeric sealants could potentially be the solution to plugging these fractures.
The application is based on the transport and reaction of a low-pH poly(acrylic acid) polymer through fractures in strongly alkaline cement. The pH-sensitive microgels viscosify after neutralization with cement to become highly swollen gels with substantial yield stress that can block fluid flow. Experiments in a cement fracture determined the effects of the viscosification and gel deposition with real-time visual observation and measurements of pressure gradient and effluent pH. Although the pH-triggered gelling mechanism and rheology measurements of the polymer gel show promising results, the polymer solution undergoes a reaction caused by the release of calcium cations from cement that collapses the polymer network (syneresis). It produces an undesirable calcium-precipitation byproduct that is detrimental to the strength and stability of the gel in place. As a result, gel-sealed leakage pathways that were subjected to various degrees of syneresis often failed to hold backpressures.
Multiple chemicals were tested for pretreatment of cement cores to remove calcium from the cement surface zone to inhibit syneresis during polymer placement. A chelating agent, sodium triphosphate (Na5P3O10), was found to successfully eliminate syneresis without compromising the injectivity of polymer solution during placement. Polymer-gel strength is determined by recording the maximum-holdback pressure gradients during liquid-breakthrough tests after various periods of pretreatment and polymer shut-in time. Cores pretreated with Na5P3O10 successfully held up to an average of 70 psi/ft, which is significantly greater than the range of pressure gradients expected in CO2-storage applications. The use of such inexpensive, pH-triggered polyacrylic acid polymer allows the sealing of leakage pathways effectively under high-pH conditions.
A Recycle Analysis for Converting Used Oil into Diesel to Support the Power System During the Drilling Process
Authors: Kasozi Anthony 
Published: July 2016

Abstract
The primary goal is to convert the used oil into valuable diesel to run the heavy engines of the power system at the drilling rig. A separate heat generating system will generate enough heat to the thick-walled containing tank known as a boiler. The used oil is sent through a boiler at very high temperatures and then into a distillation column. At various temperatures, various products are produced. But for the purpose of attaining diesel, more attention is put on a temperature range of 482 to 662°F. When the used oil is heated within the boiler, it produces vapors that are sent into a distillation column. As the vapor rises up the distillation column, it cools at a certain temperature into a liquid and this is the diesel required. The end product works in most diesel engines and mainly the heavy diesel engines of the power system to a drilling facility. This kind of diesel produces less smoke and less noise than regular diesel fuel.
The recovery of valuable diesel shows advantage over the highly costly refined diesel. This is because several gallons per hour of valuable diesel can be produced from this process. There is no wastage in this case because all the kinds of used oil are recycled into very useful diesel to re-benefit the oil and gas sector. This in turn helps to reduce the environmental threat due to pollution by the waste oil. This recycling technique is generally known as pyrolysis. It breaks down the waste oil into a mix of gases, liquids, and a small amount of solids. The gases and liquids are then converted into gasoline or diesel fuel. The source of the waste or used oil is growing in volume as millions of people are adopting fuel driven machines, like cars and generators.
