Authors: Gómez-Mármol Alberto , Sánchez-Alcaraz Martínez Bernardino Javier , Bazaco Belmonte María Jesús
Published: September 2017

El objetivo de esta investigación ha sido conocer la relación entre los hábitos sedentarios, la práctica de actividad física extraescolar y el índice de diversión en las clases de educación física. La muestra participante estuvo compuesta por 317 adolescentes (158 chicos y 159 chicas) con edades comprendidas entre los 11 y los 16 años (M = 12,65; DE = 0,98) que estudiaban en dos centros públicos de enseñanza secundaria. Como instrumentos de recogida de información se administraron los cuestionarios Test Corto Krece Plus y Escala de Diversión de la Actividad Física (PACES). Los resultados mostraron niveles superiores de la diversión frente al aburrimiento en las clases de Educación Física y niveles de diversión similares en chicos y en chicas mientras que, a medida que los alumnos pertenecen a cursos superiores, perciben que sus clases son más aburridas. Por otro lado, los datos mostraron que los escolares dedican más de tres horas a la semana para actividades físico-deportivas y más de una hora diaria a actividades sedentarias, así como una mayor prevalencia de la inactividad física en chicas respecto a chicos. Finalmente, un menor aburrimiento hacia las clases de Educación Física se asoció con mayores niveles de actividad físico-deportiva semanal.

El judo de alto rendimiento se encuentra en continua evolución, explorándose nuevas formas de enseñanza y entrenamiento, que faciliten conducir al judoca hacia el éxito.
El objetivo del presente trabajo fue analizar las relaciones que se establecen entre los diferentes tipos de motivación autodeterminada, necesidades psicológicas básicas, ansiedad cognitiva, ansiedad somática y autoconfianza en judocas competidores.
Se analizó una muestra de 124 judocas competidores, 36 mujeres y 88 hombres pertenecientes a 16 clubes de toda España, cuyas categorías iban desde infantil hasta senior, con edades comprendidas entre los 12 y los 37 años.
Para llevar a cabo dicho estudio, se pasaron los cuestionarios de Behavioral Regulation in Sport Questionnaire, para medir el nivel de motivación autodeterminada; el Psychological Need Satisfaction in Exercise Scale, para medir la satisfacción de las necesidades psicológicas básicas y el Revised Competitive State Anxiety Inventory, para medir el estado de ansiedad.
Los resultados mostraron que la motivación intrínseca, correlacionó de forma positiva y significativa con la necesidad psicológica básica de competencia además de la autoconfianza en su dimensión intensidad. Por otro lado, la desmotivación, la regulación externa y la ansiedad somática en su dimensión intensidad, correlacionaron negativa y significativamente con la motivación intrínseca.
Por consiguiente, los entrenadores tendrían que satisfacer las necesidades psicológicas básicas de los judocas, con el fin de provocar un aumento de las formas de motivación más autodeterminadas, pudiendo originar ello una mejora de la autoconfianza y una reducción de los niveles del estado de ansiedad.

Authors: Aramide Fatai Olufemi , Popoola Patricia Abimbola
Published: September 2017

The effects of the additives (silicon carbide and titania) and sintering temperatures on the phases developed, physical and mechanical properties of sintered mullite-carbon ceramic composite produced from kaolin and graphite was investigated. The kaolin and graphite of known mineralogical composition were thoroughly blended with 5 and 3 (vol.) % silicon carbide and titania respectively. From the homogeneous mixture of kaolin, graphite and titania, standard samples were prepared via uniaxial compaction. The test samples produced were subjected to firing (sintering) at 1300˚C, 1400˚C and 1500˚C. The sintered samples were characterized for the developed phases using x‐ray diffractometry analysis, microstructural morphology using ultra‐high resolution field emission scanning electron microscope (UHRFEGSEM). Various physical and mechanical properties were determined. It was observed that the addition of SiC/TiO2 additives to the samples made them to possess very low oxidation indices .This also resulted in improvement in the bulk densities and cold crushing strength of the sample when compared with those without additives. It was concluded that the addition of SiC/TiO2 additives improves on the high temperature oxidation resistance of the mullite-carbon ceramic composite sample.

Quantitative Measurement of Osseous Pathology in Advanced Glenohumeral Osteoarthritis
Authors: Iannotti Joseph P. , Jun Bong-Jae , Patterson Thomas E. , Ricchetti Eric T.
Published: September 2017

Background:

Osteoarthritis of the glenohumeral joint has typical patterns of deformity as described by Walch et al. However, more severe glenoid pathology may be difficult to classify. The purpose of this study was to use 3-dimensional computed tomography (3-D CT) imaging analysis to define common pathologic subtypes that can be differentiated from the current Walch classification.

Methods:

We performed quantitative measurements of premorbid and pathologic anatomy using preoperative 3-D CT scans from 155 cases of advanced glenohumeral osteoarthritis that underwent anatomic or reverse total shoulder arthroplasty. We defined premorbid glenohumeral anatomy on the basis of previously validated methods using 3-D glenoid vault and humeral best-fit circle models including the premorbid glenoid version, joint-line medialization, and humeral-glenoid alignment (HGA). We determined the anatomic features that differentiate new glenoid morphologic subtypes from the existing Walch classification both qualitatively and quantitatively.

Results:

We defined 2 new glenoid subtypes (B3 and C2) for which the glenoid pathology and humeral alignment were not defined in the original Walch classification. The B3 glenoid has high pathologic retroversion, normal premorbid version, and acquired central and posterior bone loss that, on average, is greater than that of the B2 glenoid. The C2 glenoid is dysplastic with high pathologic retroversion, high premorbid version, and acquired posterior bone loss, giving it the appearance of a biconcave glenoid with posterior translation of the humeral head. This C2 glenoid can be confused with the B2 glenoid.

Conclusions:

The B3 and C2 patterns have qualitative and quantitative differences that may result in different clinical outcomes than classic B2 or C types; therefore, our findings suggest that these new subtypes should be included in a new or modified classification system.
In-Hospital Complications Following Ankle Arthrodesis Versus Ankle Arthroplasty
Authors: Odum Susan M. , Van Doren Bryce A. , Anderson Robert B. , Davis W. Hodges
Published: September 2017

Background:

Ankle arthrodesis has been the traditional surgical treatment for end-stage hindfoot arthritis. However, utilization of total ankle arthroplasty (TAA) is increasing as surgical techniques and implants have substantially improved. The purpose of this study was to compare the U.S. national rates of perioperative (in-hospital) complications between a statistically matched cohort of patients who underwent either an ankle arthrodesis or a TAA.

Methods:

Data from the 2002 to 2013 Nationwide Inpatient Sample releases were analyzed. The International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) procedure codes were used to identify 4,192 patients treated with TAA (ICD 81.56) and 16,278 treated with ankle arthrodesis (ICD 81.11). ICD-9-CM diagnosis codes were utilized to identify major and minor in-hospital complications, and mortality was determined using the Uniform Bill patient disposition. The arthrodesis and TAA groups were matched with regard to age, sex, race, surgery year, hospital type, comorbidities, adjunctive procedures, and surgical indication. Unadjusted and adjusted in-hospital complication risks were compared between groups using the Fisher exact test and multiple logistic regression analysis.

Results:

We were able to statistically match 1,574 patients who underwent a TAA (37.5%) with a patient who underwent arthrodesis. A major in-hospital complication occurred in 8.5% (134) of the 1,574 patients in the ankle arthrodesis group compared with 5.3% (84) of the 1,574 in the TAA group (p < 0.001) whereas a minor complication was found in 4.7% (74) in the ankle arthrodesis group compared with 5.9% (93) in the TAA group (p = 0.14). There were no deaths in either group. After adjusting for case mix, we found that ankle arthrodesis was 1.8 times more likely to be followed by a major complication (odds ratio [OR] = 1.78, 95% confidence interval [CI] = 1.32 to 2.39) whereas the minor complication rate was 29% lower in that group (OR = 0.71, 95% CI = 0.45 to 1.13).

Conclusions:

In a matched cohort of 3,148 patients treated with either TAA or ankle arthrodesis, ankle arthrodesis was associated with a 1.8 times higher risk of a major complication but a 29% lower risk of a minor complication. Our findings are consistent with other studies that have shown TAA to be a safe procedure in the inpatient environment.

Flexion-Type Supracondylar Humeral Fractures
Authors: Flynn Kelly , Shah Apurva S. , Brusalis Christopher M. , Leddy Kelly , Flynn John M.
Published: September 2017

Background:

The vast majority of displaced pediatric supracondylar humeral fractures can be treated successfully with closed reduction and percutaneous pinning. The need for open reduction is difficult to determine a priori and is typically due to the failure of closed reduction attempts or persistent limb ischemia. The aims of this study were to determine the prevalence of flexion-type supracondylar humeral fractures, the rate of open reduction for flexion-type fractures, and the predictive impact of ulnar nerve injury on the need for open reduction for flexion-type supracondylar humeral fractures.

Methods:

We developed a database of consecutive pediatric supracondylar humeral fractures treated operatively at a tertiary care pediatric trauma center from 2000 to 2015. Data recorded included age, mechanism of injury, fracture type (open or closed), fracture pattern (flexion-type or extension-type), concomitant skeletal injury, neurovascular injury, treatment, and surgeon. Radiographs of all flexion-type supracondylar humeral fractures were reviewed in order to confirm the classification of the injury pattern. The rate of open reduction for fractures with a flexion-type injury pattern and for such fractures with and without ulnar nerve injury at presentation was assessed.

Results:

Of 2,783 consecutive pediatric supracondylar humeral fractures treated by surgeons at our center, 95 (3.4%) were flexion-type fractures. Ulnar nerve injury was noted for 10 (10.5%) of the 95 flexion-type fractures. Open injuries were identified at presentation in 3 (3.2%) of the 95 cases. Among closed fractures, 21 (22.8%) of 92 flexion-type fractures required open reduction compared with 50 (1.9%) of 2,647 extension-type fractures (odds ratio [OR] = 15.4; 95% confidence interval [CI] = 8.8 to 27.0; p < 0.001). Among closed flexion-type fractures, open reduction was performed in 6 (60%) of 10 fractures with associated ulnar nerve injury and in 15 (18.3%) of 82 fractures without ulnar nerve injury (OR = 6.7; 95% CI = 1.7 to 26.7; p = 0.003).

Conclusions:

Among closed supracondylar humeral fractures, the flexion-type injury pattern was associated with a 15.4-fold increase in the odds of open reduction. The presence of an ulnar nerve injury at presentation resulted in an additional 6.7-fold higher risk of open reduction among flexion-type supracondylar humeral fractures. Patients and families should be counseled regarding the high rate of open reduction for flexion-type supracondylar humeral fractures, particularly those with an associated ulnar nerve injury.

Improved Safety and Cost Savings from Reductions in Cast-Saw Burns After Simulation-Based Education for Orthopaedic Surgery Residents
Authors: Bae Donald S. , Lynch Hayley , Jamieson Katherine , Yu-Moe C. Winnie , Roussin Christopher
Published: September 2017

Background:

The purpose of this investigation was to characterize the clinical efficacy and cost-effectiveness of simulation training aimed at reducing cast-saw injuries.

Methods:

Third-year orthopaedic residents underwent simulation-based instruction on distal radial fracture reduction, casting, and cast removal using an oscillating saw. The analysis compared incidences of cast-saw injuries and associated costs before and after the implementation of the simulation curriculum. Actual and potential costs associated with cast-saw injuries included wound care, extra clinical visits, and potential total payment (indemnity and expense payments). Curriculum costs were calculated through time-derived, activity-based accounting methods. The researchers compared the costs of cast-saw injuries and the simulation curriculum to determine overall savings and return on investment.

Results:

In the 2.5 years prior to simulation, cast-saw injuries occurred in approximately 4.3 per 100 casts cut by orthopaedic residents. For the 2.5-year period post-simulation, the injury rate decreased significantly to approximately 0.7 per 100 casts cut (p = 0.002). The total cost to implement the casting simulation was $2,465.31 per 6-month resident rotation. On the basis of historical data related to cast-saw burns (n = 6), total payments ranged from $2,995 to $25,000 per claim. The anticipated savings from averted cast-saw injuries and associated medicolegal payments in the 2.5 years post-simulation was $27,131, representing an 11-to-1 return on investment.

Conclusions:

Simulation-based training for orthopaedic surgical residents was effective in reducing cast-saw injuries and had a high theoretical return on investment. These results support further investment in simulation-based training as cost-effective means of improving patient safety and clinical outcomes.

Trunnionosis in Total Hip Arthroplasty
Authors: Weiser Mitchell C. , Lavernia Carlos J.
Published: September 2017

➤ The etiology of clinically relevant trunnion corrosion remains to be fully understood, but appears to be multifactorial with synergy among implant-based, surgeon-based, and patient-based factors.

➤ Trunnion corrosion causing an adverse local tissue reaction (ALTR) typically manifests as delayed onset of groin, buttock, or thigh pain after primary total hip arthroplasty.

➤ Trunnionosis is probably underreported since it often causes osteolysis and loosening, and the awareness of the problem, although increasing, is not universal.

➤ Measurement of serum cobalt and chromium ions and advanced cross-sectional imaging, including metal artifact reduction sequence magnetic resonance imaging, can aid in diagnosis.

➤ Revision for trunnion corrosion-induced ALTR can often be accomplished with a head and liner exchange, with retention of the acetabular and femoral components.

➤ The surgeon should be aware of implant recalls and be cognizant of ongoing litigation against implant manufacturers.

➤ The surgeon should strive to preoperatively identify the angle and type of taper in the well-fixed stem and request that the proper implants are available for the revision total hip arthroplasty.
Optimal Implementation Strategy of Carbon Emission Reduction Policy Instruments in Consideration of Cost Efficiency
Authors: Li Xiangfei , Qin Qin , Gao Yang
Published: September 2017

In this paper, regulatory and optimum programming model has been adopted. Considering the costs of emission reduction, supervision and penalty, we went all out to analyze the optimal decision of cost efficiency of regulators when implementing these three policy instruments: carbon emission standards, carbon emission trading permissions, and carbon taxes as well. Its result has indicated: In strict accordance with control target of total carbon emissions, regulators are willing to render social and economic cost able to achieve the goal of optimal cost efficiency by regulating carbon emission standards and supervising marginal cost caused by variations in the probability; fortunately, under the conditions of low supervisory cost and certain criteria which is met, the implementation of carbon emission trading permissions could provide social and economic cost with opportunities to realize that objective; through comparative analysis, carbon emission trading permissions have the advantages of higher efficiency than carbon emission standards on the premise of incomplete information. During the implementation of carbon taxes strategy, when there exists uncertainty information in the enterprises reduction behaviors, the condition which enterprises can fully comply with is the tax rate level is not higher than marginal penalty function; the tax rate level of enterprises perfect compliance ought not to be lower than the division of marginal penalty cost and marginal supervisory cost. The optimal strategy of enterprises imperfect compliance is that regulators varying the marginal cost of emission standards is equal to varying that of supervisory probability.
On Consistency in AHP and Fuzzy AHP
Authors: Liu Fang , Peng Yanan , Zhang Weiguo , Pedrycz Witold
Published: September 2017

The analytic hierarchy process (AHP) is used widely for analyzing decisions made in various real-world applications. Its basic idea is to construct a hierarchy of concepts encountered in a given decision problem and to choose the best alternative according to pairwise comparison matrices given by the decision maker. Under the assumption of fully rational economics, a reasonable decision should be consistent. It becomes an important issue on how to analyze and ensure the consistency of comparison matrices together with the judgments of the decision maker. The main objectives of the present paper are threefold. First, we review the basic idea and methods used to define the consistency and the transitivity of multiplicative reciprocal matrices, additive reciprocal matrices and comparison matrices with fuzzy interval and triangular fuzzy numbers. The existing controversy behind the applications of fuzzy set theory to the AHP in the literature is presented. Second, the consistency of the collective comparison matrices in group decision making based on AHP and fuzzy AHP is further analyzed. We point out that the weak consistency of preference relations with fuzzy numbers in fuzzy AHP and group decision making should be investigated comprehensively. Third, under the consideration of the vagueness in the process of evaluating the judgements, a new concept of fuzzy consistency of comparison matrices in the AHP is given.
Bioelectrochemical nitrogen removal as a polishing mechanism for domestic wastewater treated effluents
Authors: Sander E. M. , Virdis B. , Freguia S.
Published: September 2017

Addition of an external carbon source is usually necessary to guarantee a sufficiently high C/N ratio and enable denitrification in wastewater treatment plants (WWTPs). Alternatively, denitrification processes using autotrophic microorganisms have been proposed i.e., with the use of H2 as electron donor or with the use of cathodic denitrification in bioelectrochemical systems (BES), in which electrons are transferred directly to a denitrifying biofilm. The aim of this work was to investigate and demonstrate the feasibility of applying an easy-to-operate BES as a polishing mechanism for treated secondary clarified effluent from a municipal WWTP, containing low levels of organic matter, buffer capacity and low concentrations of remaining nitrate. In the proposed system, nitrogen removal rates (0.018–0.121 Kg N m−3 d−1) increased with the nitrogen loading rates, suggesting that biofilm kinetics were not rate limiting. The lowest energy consumption for denitrification was 12.7 kWh Kg N−1, equivalent to 0.021 kWh m−3 and could be further reduced by 14% by adding recirculation circuits within both the anode and cathode.

Authors: Espana-Sanchez Beatriz Liliana , Avila-Orta Carlos Alberto , Padilla-Vaca Luis Felipe , Barriga-Castro Enrique Diaz , Soriano-Corral Florentino , Gonzalez-Morones Pablo , Ramirez-Wong Diana Guadalupe , Luna-Barcenas Gabriel
Published: September 2017

Background:

Propagation of pathogens has considered an important health care problem
due to their resistance against conventional antibiotics. The recent challenge involves the design of
functional alternatives such as nanomaterials, used as antibacterial agents. Early stages of antibacterial
damage caused by metallic nanoparticles (NPs) were studied by Transmission Electron Microscopy
(TEM) and combined Scanning Transmission Electron Microscopy with High Angle Annular
Dark Field (STEM-HAADF), aiming to contribute to the elucidation of the primary antibacterial
mechanism of metallic NPs.

Methods:

We analyze the NPs morphology by TEM and their antibacterial activity (AA) with different
amounts of Ag and Cu NPs. Cultured P. aeruginosa were interacted with both NPs and processed
by TEM imaging to determine NPs adhesion into bacteria wall. Samples were analyzed by combined
STEM-HAADF to determine the NPs penetration into bacterium and elemental mapping were done.

Results:

Both NPs displays AA depending on NPs concentration. TEM images show NPs adhesion
on bacterial cells, which produces morphological changes in the structure of the bacteria. STEMHAADF
also proves the NPs adhesion and penetration by intracellular localization, detecting Ag/Cu
species analyzed by elemental mapping. Moreover, the relative amount of phosphorus (P) and sulfur
(S) increases slightly in P. aeruginosa with the presence of NPs. These elements are associated with
damaged proteins of the outer cell membrane.

Conclusions:

Combined microscopy analyses suggest that the early stages of antibacterial damage
caused by alteration of bacterial cell wall, and can be considered a powerful tool aiming to understand
the primary antibacterial mechanism of NPs.
Islamic Scientific Epistemology in Al-Jabiri Perspective
Authors: Zohdi Ahmad
Published: September 2017

After Europe experienced renaissance period, it seems that Arab or Islamic countries till now have difficulty to achieve the glory like the era of prophet Muhammad (Rasulullah), Umayyah, Abbasid to the glory of Islam in the Spanish. As one of Islamic thinker (expert), Al-Jabiri arguing that the solutions offered by many experts were not appropriate with the nature concept. Furthermore, He then proposed a critical construction of Arabian epistemological knowledge by analyzing critically the process of Arabian cultural formation. He concluded that the Islamic reasoning had been "dead" because there are no more innovations given since the codification period (ashr at-tadwin) of various scientific fields (tabwib al-ilm) in the middle of 2ndcentury and 3rdcentury of hijri. Since the period, all Islamic epistemologist concept that was born at that time used as a theoretical framework (al-ithar al-marji'i) for the Islamic reasoning until now. Al-jabiri concluded the mainstream Islamic epistemology have existed in the era has three typologies, namely bayani, irfani and burhani. However, ironically the bayani epistemology much more about the Arabian reasoning, so that it created one civilization that is called fiqh civilization (hadlarahfiqh). However, irfani epistemology tends to bring Islamic view into irrational reason. While burhani epistemology is very lacked attention on Islamic view. This thing becomes stumbling to create modern Arab or Islamic era.

The study was a qualitative research. The subjects in the study were kindergarten principals, kindergarten teachers and parents. The data were gathered by means of observation, interview and documentation. For the data analysis, the researcher selected the qualitative descriptive data analysis method. The results of the study were as follows. First, the concept of educational quality improvement in the early childhood mentoring institutions/ kindergarten has been improveed from the vision, the mission and the objectives and the concept includes the aspects of planning, process and output which has synergy from one to another. The planning has been formulated in the curriculum, the syllabus and the daily activity plan. Second, the approach, the strategy and the technique of quality improvement has maximized the well-qualified schools’ resources, have been supported by the sufficient facilities and have been funded by the sufficient budget. Third, the supporting factors within the quality improvement of early childhood mentoring institutions/kindergarten have been the increasing awareness within the society toward the significance of early childhood mentoring institutions, the massive socialization conducted by the Office of Education through the provision of training programs in relation to the early childhood mentoring institution/kindergarten management and the human resources empowerment toward developing the quality of early childhood mentoring institutions. Fourth, the inhibiting factors within the quality improvement of early childhood mentoring institutions have been the lack of society care and participation, the less quality human resources that early childhood mentoring institutions have, the fund limitation, the facility limitation and the lack of program management effectiveness.Keywords: development, educational quality, kindergarten

Objetivo. El objetivo evaluar la ocurrencia de protozoos gastrointestinales en terneros lecheros y de identificar posibles factores de riesgo para infección. Materiales y métodos. Se recogieron 243 muestras de heces de terneros de hasta 60 días de edad en 43 granjas lecheras ubicadas en la región del oeste del estado de Santa Catarina, Brasil. Las muestras fueron examinadas por la técnica de centrifugación-flotación. Resultados. Como resultado, Giardia estaba presente en 26.75% (65/243) de todas las muestras, Eimeria en 21.81% (53/243), y Cryptosporidium en 20.99% (51/243). Además, 46.50% (113/243) de las muestras fueron negativas para cualquier protozoos, mientras que 39.10% (95/243) y 14.40% (35/208) mostraron infecciones simples y mixtas, respectivamente. Hubo una mayor asociación entre Cryptosporidium y Giardia (6.99%) en los casos de infecciones mixtas. Sin embargo, la asociación de triple protozoos tenía la menor prevalencia de infecciones mixtas (2.06%). Epidemiológicamente, se aplicó un cuestionario para determinar los factores de riesgo para estas infecciones parasitarias. Se han identificado algunos factores de riesgo de infecciones por Cryptosporidium, destacando manejo de la alimentación, periodo de tiempo que los terneros permanecieron con sus madres (vacas), y el contacto con los perros; el riesgo de contraer Giardia incrementado en función de la fuente de la leche, mientras que el tipo de suelo de las camas, y la edad fueron nombrados como los riesgos de factores de Eimeria. Conclusiones. Es posible confirmar que Giardia, Cryptosporidium y Eimeria pueden infectar a terneros lecheros, y el conocimiento de algunos factores de riesgo asociados a la infección en terneros.
ENTRE VÍNCULOS E VEÍCULOS: a representação da mulher rural a partir da apropriação das TICs
Authors: Silva Marcela Guimarães e
Published: September 2017

Este estudo tem como objetivo apresentar alguns apontamentos sobre o processo de representação da mulher rural na gestão da propriedade familiar a partir da convergência de políticas públicas no âmbito da extensão rural brasileira com recorte direcionado ao acesso às tecnologias da informação e comunicação (TICs). Para tanto, apresenta brevemente a trajetória das políticas públicas de assistência técnica e extensão rural, que encontra-se historicamente entrelaçada aos processos comunicativos e aos meios de comunicação, para situar o papel da mulher rural nesse contexto. Posteriormente, propõe uma reflexão sobre as implicações das políticas de reconhecimento da agricultura familiar e de acesso às TICs como uma convergência possível para promover a participação da mulher rural. Na sequência aborda questões de gênero a partir da realidade de mulheres agricultoras do município de São Borja, estado do Rio Grande do Sul, Brasil, atendidas pela Emater/RS – Ascar e as suas relações com esta e outras instituições por meio da apropriação das TICs em seu cotidiano. E por fim, apresenta algumas reflexões sobre a convergência entre as políticas e, consequentemente a inclusão dessas mulheres no contexto do desenvolvimento rural no qual estão inscritas as TIC.

The aim of the study was to determine the effect of diesel fuel (ON) on the germination of seeds and seedlings condition of Festuca rubra L. ssp. commutata variety Musica and naphthalene (Nf) on the same characteristics of the variety Nimba. It was concluded, the test parameters were significantly different in comparison to the control, but in most cases, there was no difference between them. Naphthalene caused more root embryo growth limitation, but less than diesel, inhibited the growth of aboveground parts. Germination capacity tested varieties were similar and were as follows: for Musica and ON 23 and 21% respectively to doses, and to Nimba variety and Nf – 25 and 23%.

Published: September 2017

This paper addresses the mechanical behavior and permeability characteristics of the unloading coal under different water pressures in the TOP2518-comprehensive- rock-testing system. With the use of the computed tomography scan tests, the 3-D crack distribution characteristics of the fractured coal are obtained and reconstructed. The difference in the 3-D crack distribution of unloading coal induced by different water pressures is also analyzed in detail. The results show that, as the water pressure changes from 0 MPa to 8 MPa, the peak stress of unloading coal gradually decreases, and that the variation degree of permeability of the coal samples increases significantly comparing with the initial permeability.

For the investors, financial statement is a benchmark of investors in assessing the company's performance. In fact, investors are not always receiving the accurate company's financial statements information and its levels of fairness are in doubt. The financial statement analysis with using financial ratios is not enough. The investors may need to use alternatives financial statement analyses techniques that reflect the actual company's performance. Therefore, both of the investors and the prospective can use Economic Value Added (EVA) and Market Value Added (MVA) analysis. With these technical analyses, the investors may know the company's performance where they are invested or to be used as a place to invest whether it has value added or not. With the results of these analyses, it is the expected for the investors to be more confident in making decision whether to buy, sell or hold the ownership in the company.
A Phenomenological Study of the Lived Experiences of the Generation X and Y Entrepreneurs
Authors: Khor Patrick
Published: September 2017

This qualitative phenomenological approach examined the Generation X and Y cohorts in terms of their lived experience towards the  entrepreneurial journey in Singapore, which can consequently fill empirical gap on entrepreneurship among generational cohorts of Asian entrepreneurs.  The study sample comprised  15 generation X and 15 Y Singaporean entrepreneurs from 30 companies who identified their involvement in starting a business venture and in the day-to-day running of the business. Using NVIVO to cull down key components and ideas from the data, the study revealed that Generation X and Generation Y to have similar work attitudes, values and behaviours. The differences between the generations include differences in age, experience as well as obligations in life such as to one’s family. Further studies are needed to examine the differences of these cohorts in terms demographic, psychological and social variables to provide additional insights and identify contributing factors to successful entrepreneurial venture.

Paper presented to the Special Libraries Association, 83rd Annual Conference, San Francisco, Ca., on June 10 1992. Defines, discusses and lauds new technology for research and pedagogy in the electronic age in the near future both nationally and internationally. Gives examples of usage ranging from reconstruction of Dead Sea Scrolls to planning baseball strategy to answering medical questions in Africa. Alerts both teachers and librarians to expect change and maintains that librarians will not be passive consultants but knowledge managers. Discusses the concept that lecturing is an unnatural act and predicts that within next two years automated instructional systems will be implemented. Says that delay is caused not by lack of machinery but lack of courseware. Discusses limits of present software such as CD-ROM. Advocates networked, digital video for future educational technology, i .e. Computer-Mediated Learning Systems, although concedes that technology cannot meet all instructional needs.
