A study of deterioration of cement paste due to acid attack using X-ray computed micro-tomography
Authors: Ramaswamy Koodalloor P. , Santhanam Manu
Published: October 2017

Cementitious materials are highly vulnerable to rapid and serious deterioration in aggressive acidic environments. The aim of this paper is to understand the microstructure deterioration of cement paste due to acid attack using the non-destructive technique called X-ray computed micro-tomography (micro-CT). To investigate this deterioration, an accelerated static immersion based leaching test with periodic abrasive action was performed on cement paste specimens of size 10 × 10 × 60 mm, prepared using ordinary Portland cement with a water-to-cement ratio of 0·40. After 28 d of initial curing in saturated lime water, specimens were exposed to 1% sulfuric, 1% hydrochloric, 0·5 M acetic and 0·5 M citric acid solutions for a maximum period of 6 weeks. X-ray micro-CT was used for imaging the deteriorated specimens to investigate the changes in microstructure. Various parameters related to degradation were also deduced based on the image analysis performed on the CT images in order to evaluate the performance of the cement paste in various acid solutions. Parameters such as altered depth/area could be considered as primary indicators of attack, which can be best captured and analysed using X-ray CT.
Influence of triethanolamine on cement pastes at early age of hydration
Authors: Jachiet Marie , Azéma Nathalie , Le Saoût Gwenn , Garcia-Diaz Eric , Kocaba Vanessa
Published: October 2017

Accelerators (or activators) are commonly used as additives in cement to advance setting and/or hardening. Activation is often associated with the favoured hydration of particular cementitious phases, which can be induced by complexation mechanisms. However, the dispersion state of pastes with admixtures may also influence hydration rates. The aim of this paper is to highlight the correlation between mesostructural organisation and chemical reactivity of cement pastes with an additive. The affinity of triethanolamine (TEA), an activator molecule, with cement grains was assessed by measurement of total organic carbon. Moreover, the influence of the amine on the dispersion state, sedimentation kinetics and rheological behaviour was studied. Finally, X-ray diffraction, aluminium nuclear magnetic resonance spectroscopy and isothermal calorimetry were used in order to study the chemical reactivity of cement in the presence of the admixture. The combination of these granular and chemical characterisations helped to understand the mode of action of TEA.
The effects of admixtures of inorganic hydrates on the hydration hardening of magnesium potassium phosphate cement
Authors: Zhao Sixie , Yan Hua , Zhang Hansong , Wang Hongtao , Li Yuntao , Hu Zhide , Sun Huaqiang
Published: October 2017

Admixtures of Na2B4O7·10H2O (NB), Ca(NO3)2·4H2O (CN) and Na2SO4·10H2O (NS) are studied to discover how they affect the work performance, hydration-induced increases in temperature and mechanical performance of magnesium potassium phosphate cements (MKPCs). Analytical methods such as X-ray diffraction spectroscopy, eight-channel microcalorimetry and thermogravimetric-differential scanning calorimetry are used to investigate the underlying mechanisms of these changes. Incorporation of a single retarder (NB) results in short MKPC hardening times and low early strengths. Admixture with 1·5% or more NB and CN effectively lengthens the hardening time of MKPC, but greatly decreases its fluidity. Incorporation of NB, CN and NS in the ratios 1·5%:1·5%:5% results in an initial hardening time of 37·02 min and the appearance of two temperature peaks in the hydration temperature curve. The resulting cement mix has fluidity of 115 mm and strength of 52·56 MPa after 12 h of hydration. Reaction between NB and CN creates a calcium borate film that envelopes magnesium oxide particles, preventing dissolution of magnesium oxide and generation of the hydrated product MgKPO4·6H2O (MKP), thus slowing down the hydration process. Incorporation of an appropriate quantity of NS endows fluidity of MKPC that can reach 125 mm, owing to crystal waters released during solvation and changes in phase.
International Transfer Pricing and Tax Avoidance: Evidence from Linked Trade-Tax Statistics in the UK
Authors: Liu Li , Schmidt-Eisenlohr Tim , Guo Dongxian
Published: October 2017

This paper employs unique data on export transactions and corporate tax returns of UK multinational firms and finds that firms manipulate their transfer prices to shift profits to lower-taxed destinations. It uncovers three new findings on tax-motivated transfer mispricing in real goods. First, transfer mispricing increases substantially when taxation of foreign profits changes from a worldwide to a territorial approach in the UK, with multinationals shifting more profits into low-tax jurisdictions. Second, transfer mispricing increases with a firm's R&amp;amp;D intensity. Third, tax-motivated transfer mispricing is concentrated in countries that are not tax havens and have low-to-medium-level corporate tax rates.

Authors: Ahumada Tello Eduardo
Published: October 2017

La competitividad es un tema de estudio que afecta a diferentes aspectos del individuo y de las organizaciones. La exigencia del ambiente moderno sobre la adquisición de habilidades y capacidades impulsa diversos estudios sobre la satisfacción que se logra al intentar cumplir con todos los requerimientos en el proceso de desarrollo. En esta investigación se busca encontrar una relación entre competitividad y las variables de felicidad, bienestar y educación para validar la existencia de influencia significativa entre ellas. Para estos efectos se utilizó un análisis de correlación y de ecuaciones estructurales tipo cuantitativo en un estudio de caso con una muestra de 106 personas egresados universitarios. Los hallazgos principales indican que la felicidad es una percepción que puede presentarse como independiente de la competitividad. En cambio, el bienestar y la educación mantienen una relación más significativa entre los encuestados.ABSTRACTCompetitiveness is a subject of study that affects different aspects of the individual and of the organizations. The demand that the modern environment towards the acquisition of skills, abilities and capacities impels diverse studies on the satisfaction that is obtained when trying to fulfill all the requirements in the process of development. In this research, we try to find a relation between competitiveness and the variables of happiness, welfare and education to validate the existence or significant influence among them. For these effects a correlation analysis and quantitative structural equations were used in a case study with a sample of 106 university graduates. The main findings indicate that happiness is a perception that can be presented as independent of competitiveness. In contrast, welfare and education have a more significant relationship among respondents.

Authors: Naik Meena , Ratnani Rekha , Thaore Swati
Published: October 2017

Background: Abnormal uterine bleeding is the most common gynecological problem comprising more than 30-50% of gynecological OPD patients. There are various causes of AUB from hormonal dysfunction to endometrial cancer. In order to manage effectively it is important to diagnose accurately the cause of abnormal bleeding. This study outlines the place of hysteroscopy and its role in evaluation of intrauterine causes of AUB.Methods: This is a Retrospective cross sectional observational study conducted in department of Obstetrics and Gynaecology at CCM Medical College, Durg, Chhattisgarh. 350 Patients between 20-70 years age presenting to general gynae OPD with abnormal uterine bleeding at CCM medical college over a period of 2 years between 1st January 2015 to December 2016 were studied. All patients were subjected to thorough clinical evaluation followed by sonography and hysteroscopy. Data collected from medical records, analysed and various intrauterine causes of AUB were studied.Results: Mean age of patients in our study was 45 years with majority of patients in 40-50 year age group. predominant complaint reported was menorrhagia (52%) followed by menometrorrhagia (18.86%) and polymenorrhoea (18.58%). USG detected abnormality in 65.6 % of cases and 34.4% were normal on USG but majority of these were fibroids and ovarian cysts. However, diagnosis of specific intrauterine pathology was made in only 12.8%. Hysteroscopy detected intrauterine abnormality in 60% cases. Most common being polyp in 94 patients (26.8%) followed by hyperplastic endometrium in 74 (21.1%). 18 (5.1%) patients had polypoidal endometrium which is also type of hyperplastic endometrium. 17 (4.85%) had submucous fibroid, 4 (1.1%) had atrophic lining and 3 (0 .85%) had intrauterine adhesions. Diagnostic accuracy of hysteroscopy was found better in polyps and submucous myomas which were missed by usg and also can be missed by traditional D and C only.Conclusions: Hysteroscopy allows exclusion of intracavitary pathology as well as treatment of them in same sitting with proper tissue biopsy from the abnormal area which can be of help in proper treatment planning. Though hysteroscopy helps in diagnosing cause of AUB their proper management will depend on final histology, age of patient and fertility goals.

Authors: Bedi Upneet , Kaur Dang Bavneet
Published: October 2017

Background: Type 2 diabetes mellitus has deleterious effects on brain resulting in loss of short term memory and working memory in elderly and poorly controlled diabetic patients. Less attention has been given to the effect of diabetes on cognitive functions. Hence, the study was undertaken to study the status of short term and working memory in type 2 diabetes mellitus and to correlate it with the duration of diabetes.Methods: Study was conducted in Punjab Institute of Medical Sciences, Jalandhar, India, on 100 diabetic patients in the age group of 40-60 years. Short term memory and working memory was assessed using 4 memory tests. AVLT and VFT for short term memory and WDST and VST for working memory. The results expressed in average of total scores. One-way ANOVA followed by post hoc (t) test were used for statistical analysis.Results: Short term memory and working memory status was negatively correlated with duration of diabetes. Diabetics more than 55 years showed greater cognitive decline compared to younger age group.Conclusions: The short term and the working memory status decreased significantly in diabetic patients, which may be due to age of onset, duration, vascular dementia, hyperglycemia or hypoglycemia. These effects observed that duration, sex, age and blood glucose levels are of clinical importance as short term and working memory loss could have important practical implications for daily activities.

MicroRNAs in neuroblastoma differentiation and differentiation therapy
Authors: Sousares Michaela , Partridge Veronica , Weigum Shannon , Du Liqin
Published: October 2017

Neuroblastoma is one of the most common and aggressive types of pediatric cancers, making up about 7% of all childhood cancers. Neuroblastoma arises from the failure of neural crest cell precursors to differentiate, and inducing cell differentiation is one of the most important treatment approaches for neuroblastoma. MicroRNAs regulate gene expression by performing post-transcriptional gene modification by mainly translational suppression and mRNA degradation. The dysregulation of these molecules has been shown to be related to tumor development, tumor metastasis and drug resistance, and the promise of developing microRNA-based therapeutics for cancers has been demonstrated. Many recent studies have also provided evidence for the involvement of microRNAs in differentiation of neuroblastoma cells, suggesting the potential of developing microRNA-based differentiation therapies for neuroblastoma. Here we review the recent findings on the role of microRNAs in regulating cell differentiation, with a main focus on neuroblastoma cells. The investigations on the therapeutic potential of microRNAs in neuroblastoma therapy and differentiation therapy are also reviewed.

Body image is a dynamic entity that includes three components: perceptive, cognitive-affective and behavioral; It is constructed of characteristics such as age, sex and educational level, as well as the ideas established by the context. The interaction between the psychological and the social can lead to the development of clinically relevant behaviors. Thus, the objective of the present investigation was to know the perceptions on the male body ideal of the college students of nutrition. Through a focus group, since the qualitative-phenomenological approach and based on the participants discourse, four categories of analysis were derived. It was found that media (including social networks), cultures, stereotypes and beliefs are predominant factors in the construction of the male body ideal, which is reflected in self-esteem, health, economic, occupational or professional opportunities, and to achieve it, can be developed eating disorders symptoms or muscular dimorphic disorder symptoms. It is conclude that the focus group allows knowing the perceptions related to male body ideal by college students of nutrition, where it was showed that, also the society pressures to achieve that ideal, for example, participants express body satisfaction, but wish to modify their composition, so their beliefs determine what must be done to reach such ideal. Therefore, it is evident the importance of carrying out intervention programs at the primary level in college students, from health psychology.

The purpose of this current research is to make and implement a didactic guide based on playful activities called “Aprendo Jugando”. This is in a bid to develop the gross motor skills on the first year basic education of boys and girls at Santa Mariana Educational Unit in Riobamba. The guide was organized through a schedule, and it contains games to influence the big muscles movements. The games are intended to reinforce the basic motor skills to evaluate the coordination of the body movements such as jump, match, and jumping on one foot. The sample incorporated 20 children chosen at random. The results were obtained through a direct observation and they were registered with an observation card that was applied before and after the development of the guide. An indicator table was used. Here, the indicators were statistically analyzed, especially the ones that allowed evaluating the hypothesis significance with the use of the students test. At the end of the research, it was concluded that the application of the didactic guide develops the gross motor skills. These evidences play an essential role in the child´s life. As a result, it is recommended to use the guide in a permanent and continuous way because if a child develops the gross motor skills in an appropriate way, he would have confidence on himself. Above all, it will be easier for him to assimilate the basic fine motor skills.

Influence of Social Capital on Livelihood Outcomes for the Internally Displaced Persons in Kenya: A Social Capital Approach
Authors: Kiboro Christopher Nkonge
Published: October 2017

Social capital is increasingly recognized as important in influencing economic development, establishment of safe neighborhoods and wellfunctioning communities. There is growing evidence that communities with relatively higher stocks of social capital in form of grassroots associations appear to achieve higher levels of growth compared to societies with low stocks of social capital. This study sought to investigate the influence of social Capital on the livelihood outcomes for the internally displaced persons in Kenya. Membership to local level associations was used as a predictor of social capital. The study revealed that majority of the households that were affiliated to local level associations obtained essential services that influenced their livelihoods positively. Overall, the findings reveal that memberships in local associations (social capital) tend to insulate households from risks and other exigencies. The study recommends that government and other stakeholders such as non-governmental organizations should formulate projects and programs that seek to promote wider participation in local level associations particularly by the poor and those whose livelihoods are vulnerable.
The Impact of Computer on the Deviant Behaviors Exhibition of Teenagers : A Case Study of Albania
Authors: Brahja Eljana
Published: October 2017

Technology is placing teenagers in front of diverse choices that the virtual world enables. The purpose of this study is to explain how technology affects relationships that teenagers have with other individuals in the real world. The study's research question is: Does the use of computers affect the exhibition of deviant behaviors among teenagers? The research method used for the findings of this study is the quantitative method. Data was collected using a questionnaire. The population of the study was 1,680 teenagers from Sander Prosi and Myslym Keta high schools located in Tirana, Albania. The sample selected according to the defined criteria for completing the questionnaires is 453 students from the 10th, 11th and 12th grade. Based on the Positive Paradigm, the quantitative research method will serve to recognize the reality. Research data is processed through the SPSS statistical method and the result with the Cronbach alpha validation coefficient, α = 0.852. Based on the Interactional Theory (Thornberry, 2015), it is aimed to shed light on the behavioral patterns exhibited by teenagers who are computer users. From the research findings, students who used computer to play, and not for scientific research, were more involved in deviant behavior. They were predisposed to conflict with friends, dim relationships with people surrounding them in the real world, dropping out of school, etc. To avoid such a situation, it is recommended to strengthen the cooperation in the real world amongst parents, students, and teachers.
Diseño Y Desarrollo Metodológico Del Funcionamiento Del Nicho Ecológico De La Demanda Del Sistema Turístico
Authors: Zaquinaula Manuel Antonio Abarca
Published: October 2017

This study was designed and developed methodologically based on the operation of the ecological niche of the demand of the tourist system (based on the models of Roberto Boullón, Neil Leiper, and the World Tourism Organization). It was carried out from a systemic-mechanical approach that revolves around the well-being, health, and the decision of the demand when traveling to a tourist destination. This study however stresses that one of the main causes of mortality in the world is stress. As a result, many tourism modalities should be recipes that mitigate and/or regulate the different levels of global tourism demand. In the present essay, it was clearly explained that the faster the rotation of the two rotors of the ecological niche of the demand, the more stress accumulate their bodies. As a result of this, the acceleration will bring about the tastes, preferences, needs, demands, and tendencies of the tourists. Necessary inputs facilitates the operation and development of a destination and/or tourism system. Additionally, it allow the servers of the supply engine to adapt and/or mold to these demand inputs to achieve their satisfaction to the fullest, and also mitigates the stress that haunts them.
The Role of Extra-Articular Tenodesis in Combined ACL and Anterolateral Capsular Injury
Authors: Guenther Daniel , Irarrázaval Sebastián , Bell Kevin M. , Rahnemai-Azar Amir Ata , Fu Freddie H. , Debski Richard E. , Musahl Volker
Published: October 2017

Background:

The “gold standard” treatment of anterolateral capsular injuries in anterior cruciate ligament (ACL)-deficient knees has not been determined. The purpose of this study was to determine the effects of ACL reconstruction and extra-articular reconstruction on joint motion in the ACL-deficient knee and in the combined ACL and anterolateral capsule-deficient knee.

Methods:

An anterior tibial load of 134 N and internal tibial torque of 7 Nm were applied to 7 fresh-frozen cadaveric knees using a robotic testing system continuously throughout the range of flexion. The resulting joint motion was recorded for 6 knee states: intact, ACL-deficient, ACL-reconstructed, combined ACL and anterolateral capsule-deficient, ACL-reconstructed + anterolateral capsule-deficient, and ACL-reconstructed + extra-articular tenodesis.

Results:

Anterior tibial translation of the ACL-reconstructed + anterolateral capsule-deficient knee in response to an anterior tibial load was restored to that of the intact knee at all knee-flexion angles (p > 0.05). However, for this knee state, internal tibial rotation in response to internal tibial torque was not restored to that of the intact knee at 60° or 90° of knee flexion (p < 0.05). For the knee state of ACL-reconstructed + extra-articular tenodesis, internal rotation in response to internal tibial torque was restored to the motion of the intact knee at each of the tested knee-flexion angles (p > 0.05). Compared with the intact knee, 2 of 7 specimens showed decreased internal tibial rotation with ACL reconstruction + extra-articular tenodesis.

Conclusions:

In this study, an extra-articular tenodesis was necessary to restore rotatory knee stability in response to internal tibial torque in a combined ACL and anterolateral capsule-deficient knee. The amount of rotatory knee instability should be carefully assessed to avoid over-constraint of the knee in these combined ligament-reconstruction procedures.

Clinical Relevance:

On the basis of our findings, the surgical procedure needs to be personalized depending on the amount of rotatory knee instability in the injured knee and the amount of rotation in the contralateral knee.

Background:

The rational design and optimization of tissue engineering strategies for cell-based therapy requires a baseline understanding of the concentration and prevalence of osteogenic progenitor cell populations in the source tissues. The aim of this study was to (1) define the efficiency of, and variation among individuals in, bone marrow aspiration as a means of osteogenic connective tissue progenitor (CTP-O) harvest compared with harvest from iliac cancellous bone, and (2) determine the location of CTP-Os within native cancellous bone and their distribution between the marrow-space and trabecular-surface tissue compartments.

Methods:

Eight 2-mL bone marrow aspiration (BMA) samples and one 7-mm transcortical biopsy sample were obtained from the anterior iliac crest of 33 human subjects. Two cell populations were obtained from the iliac cancellous bone (ICB) sample. The ICB sample was placed into αMEM (alpha-minimal essential medium) with antibiotic-antimycotic and minced into small pieces (1 to 2 mm in diameter) with a sharp osteotome. Cells that could be mechanically disassociated from the ICB sample were defined as marrow-space (IC-MS) cells, and cells that were disassociated only after enzymatic digestion were defined as trabecular-surface (IC-TS) cells. The 3 sources of bone and marrow-derived cells were compared on the basis of cellularity and the concentration and prevalence of CTP-Os through colony-forming unit (CFU) analysis.

Results:

Large variation was seen among patients with respect to cell and CTP-O yield from the IC-MS, IC-TS, and BMA samples and in the relative distribution of CTP-Os between the IC-MS and IC-TS fractions. The CTP-O prevalence was highest in the IC-TS fraction, which was 11.4-fold greater than in the IC-MS fraction (p < 0.0001) and 1.7-fold greater than in the BMA fraction. However, the median concentration of CTP-Os in the ICB (combining MS and TS fractions) was only 3.04 ± 1.1-fold greater than that in BMA (4,265 compared with 1,402 CTP/mL; p = 0.00004).

Conclusions:

Bone marrow aspiration of a 2-mL volume at a given needle site is an effective means of harvesting CTP-Os, albeit diluted with peripheral blood. However, the median concentration of CTP-Os is 3-fold less than from native iliac cancellous bone. The distribution of CTP-Os between the IC-MS and IC-TS fractions varies widely among patients.

Clinical Relevance:

Bone marrow aspiration is an effective means of harvesting CTP-Os but is associated with dilution with peripheral blood. Overall, we found that 63.5% of all CTP-Os within iliac cancellous bone resided on the trabecular surface; however, 48% of the patients had more CTP-Os contributed by the IC-MS than the IC-TS fraction.

Approximately 5,168 large animals (pigs, sheep, goats, and cattle) were used for intervertebral disc research in identified studies published between 1985 and 2016. Most of the reviewed studies revealed a low scientific impact, a lack of sound justifications for the animal models, and a number of deficiencies in the documentation of the animal experimentation. The scientific community should take suitable measures to investigate the presumption that animal models have translational value in intervertebral disc research. Recommendations for future investigations are provided to improve the quality, validity, and usefulness of animal studies for intervertebral disc research. More in vivo studies are warranted to comprehensively evaluate the suitability of animal models in various applications and help place animal models as an integral, complementary part of intervertebral disc research.

Published: October 2017

➤ Technical errors such as nonanatomic tunnel placement are some of the most common causes of graft failure after primary anterior cruciate ligament reconstruction (ACLR).

➤ When considering a revision ACLR in a patient with ACL graft failure, it is crucial to perform preoperative imaging, which should include an initial radiographic series, magnetic resonance imaging, and possibly computed tomography for further assessment of tunnel locations.

➤ Revision ACLR may be performed in a 1 or 2-stage procedure depending on the size and location of the existing tunnels, bone stock, existing hardware, and infection status.

➤ Use of autograft ligament tissue for revision ACLR has been shown to correlate with higher patient-reported outcomes and a significantly lower risk of subsequent graft rupture in comparison with allograft use.

➤ Multiple studies have shown that the rate of return to the preinjury level of sport is significantly lower following revision ACLR than following primary ACLR procedures.
How CO2-Storage Mechanisms Are Different in Organic Shale: Characterization and Simulation Studies
Authors: Pu Hui , Wang Yuhe , Li Yinghui
Published: October 2017

Widely distributed organic-rich shales are being considered as one of the important carbon-storage targets, owing to three differentiators compared with conventional reservoirs and saline aquifers: (1) trapping of a significant amount of carbon dioxide (CO2) permanently; (2) kerogen-rich shale's higher affinity of CO2; and (3) existing well and pipeline infrastructure, especially that in the vicinity of existing power or chemical plants. The incapability to model capillarity with the consideration of imperative pore-size-distribution (PSD) characteristics by use of commercial software may lead to inaccurate modeling of CO2 injection in organic shale. We develop a novel approach to examine how PSD would alter phase and flow behavior under nanopore confinements. We incorporate adsorption behavior with a local density-optimization algorithm designed for multicomponent interactions to adsorption sites for a full spectrum of reservoir pressures of interests. This feature elevates the limitation of the Langmuir isotherm model, allowing us to understand the storage and sieving capabilities for a CO2/N2 flue-gas system with remaining reservoir fluids. Taking PSD data of Bakken shale, we perform a core-scale simulation study of CO2/N2 flue-gas injection and reveal the differences between CO2 injection/storage in organic shales and conventional rocks on the basis of numerical modeling.
The Optimization of Capital Structure in Maximizing Profit and Corporate Value
Authors: Effendi Kharisya Ayu
Published: October 2017

The purpose of this research was to determine the optimal capital structure which could maximize profits and corporate value. The used method was quantitative descriptive analysis. Moreover, the data used was secondarydata in the Jakarta Islamic Index (JII) from 2011 to 2015. The results of this research show that companies which have optimal capital structure are in line with the trade-off theory models. The capital structure is optimal if thedebt levels are to a certain extent so that the corporate value will increase. However, if the debt limit passes the certain degree, profit and corporate value will decrease. Meanwhile, pecking order theory in this research doesnot conform and cannot be said to be optimal because of the low debt level describing the opposite result with the theory as low profits.
