Investigación concluida sobre la incorporación de la innovación en la PYMES de las regiones Pachuca, Tula y Tepeji del Estado de Hidalgo
Authors: Hernández Gracia José Francisco , Avendaño Hernández Venancio , Carranza Sevilla Juan Alberto
Published: January 2018

En décadas pasadas, las empresas de cualquier país se desarrollaban dentro de un ambiente relativamente proteccionista, donde las exigencias del mercado interno eran mínimas y con un ambiente global de baja competición. Para lograr el desarrollo de nuevos productos en un mercado globalizado, las empresas requieren de la implementación de la innovación como una estrategia empresarial. Sin embargo, resulta demasiado difícil implementar un proceso de innovación en las distintas actividades empresariales, especialmente para las Pequeñas y Medianas Empresas (Pymes), que tienen poca experiencia y recursos limitados (Hadjimanolis, 1999).

Adicionalmente, las Pymes de los países con un bajo desarrollo industrial tienen aún serias limitaciones, pues tienen una inadecuada infraestructura y escasos apoyos gubernamentales, lo que obstaculiza la ejecución de la innovación (Hadjimanolis, 1999). Por ello, la mayoría de los estudios sobre este constructo se han realizado en los países industrializados y en un contexto de grandes empresas, ya que la mayor innovación ha sido tradicionalmente asociada con las grandes multinacionales (Vossen, 1998). Sin embargo, el interés por estudiar la innovación en las Pymes es relativamente reciente (Hadjimanolis 2000), aun cuando Schumpeter (1934) en sus primeros estudios ya reconocía la importancia de la innovación en las Pymes.

Por ello, la sobrevivencia y desarrollo de las Pymes en las regiones de Pachuca, Tula y Tepeji del estado de hidalgo dependerá en gran medida, del grado en que incorporen a la innovación dentro de sus estrategias empresariales.

La innovación en los productos y/o servicios es importante para mantener la cuota de mercado, la innovación en los procesos es importante para mantener un nivel de precios competitivos y la innovación en la gestión es importante para mantener una organización flexible (Heunks, 1998; van Auken et al., 2008).

Esta clasificación de innovación en productos, procesos y gestión será utilizada en este trabajo de investigación.

Impact of the degree of relative risk aversion, the interest rate and the exchange rate depreciation on economic welfare in a small open economy
Authors: Soriano-Morales Yazmín Viridiana , Vallejo-Jiménez Benjamín , Venegas-Martínez Francisco
Published: January 2018

This paper is aimed at assessing the impact of the degree of relative risk aversion on economic welfare for different levels of the interest rate and the exchange rate depreciation in a small open beconomy. To do this, a representative consumer-producer makes decisions on consumption, money balances, and leisure. In order to find a closed-form solution of the household’s economic welfare, it is assumed that individual’s preferences belong to the family of Constant Relative Risk Aversion (CRRA) utility functions. Several comparative statics graphical experiments about the effects of the degree of relative risk aversion on economic welfare for different levels of nominal variables are carried out. Finally, we find that, under the stated assumptions, household’s economic welfare seen as a function of the degree of relative risk aversion is responsive to different values of nominal variables.

Published: January 2018

Due to rapid urbanization, Metro Manila is facing many environmental challenges with its continuous accelerating urban growth rate. According to 2010 census of population Metro Manila accounts about one-third of the total urban population and about 13% of the total national population of Philippines. The impact of urban growth of the Metro Manila to its urban environment relating on demography, solid wastes problem and problems in water bodies as well as air pollution and greenhouse gas emissionis emphasized here in this study. The flood prone areas within the Metro Manila is about 31%, most of the risk areas located along creeks, river banks or coastal areas. Metro Manila produces total garbage equivalent to 25% of the national waste generation in which about 17% is paper wastes and about 16% are plastics. In terms of water quality classification the upper reaches of the Marikina River is of Class A, but all remaining river systems are of Class C. Accordingly, the classification of Manila Bay is of Class SB. Similarly, the quality of ambient air of the Metro Manila is also poor. Using 2010 as base year, the major contributor to greenhouse gas is from vehicular emissions followed by the stationary sources. An urgent need is felt to incorporate environmental issues into planning its urban area to reduce the risks of further environmental degradation.

Successful Information and communication technology (ICT) can cause rapid development in administrative processes. ICT strategies and ICT plans should be evaluated to align with organization visions and missions in order to achieve effective use of ICT in their organizations [1]. Efficient Software and Hardware together play a vital role giving relevant information which helps improving ways we do business, learn, communicate, entertain and work. This exposes to an environment with significant risks which are vulnerable to inside or outside attacks [2,3]. Security is a degree of protection or resistance from harm. Security can also be defined as a layer created to separate assets from threats [4]. In order to understand clearly about security, it is very important to understand important terminologies [5]. This research paper talks about important terminologies, concerns and challenges on Information System and Security Audit. This research seeks explanation from the observed phenomena, problems or behavior and thus exploratory research is used. The outcome of this research is an overview of different security concerns that must be sincerely addressed in any Information System and Security Audit.

On the Unicity Conjecture for Generalized Markoff Equation
Authors: Gaire Youb Raj
Published: January 2018

The Markoff equation x2 + y2 + z2 = 3xyz is introduced by A.A. Markoff in 1879. A famous conjecture on the Markoff equation, made by Frobinus in 1913, states that any Markoff triples (x, y, z) with x ≤ y ≤ z is uniquely determined by its largest number z. The complete solution of this equation is still open however the partial solution is given by Barager (1996), Button (2001), Zhang (2007), Srinivasan (2009), Chen and Chen (2013). In 1957, Mordell developed a generalization to the Markoff equation of the form x2 + y2 + z2 = Axyz + B where, A and B are positive integers. In 2015, Donald McGinn take a particular form of above equation with A = 1 and B = A and gave a partial solution to the unicity conjecture to this equation. In this paper, the partial solution to the unicity conjecture to the equation of the form x2 + y2 + z2 =3xyz + A where A is positive integer with A ≤ 4(x2 –1) is given.

Significant enhancement of bond strength in the roll bonding process using Pb particles
Authors: Vini Mohammad Heydari , Zadeh Omid Hossein
Published: January 2018

Composite materials and layered alloys have become an interesting topic in materials development. The roll bonding (RB) process as a solid phase method of bonding has been widely used in the manufacturing of layered strips. The poor bond strength is one of the major drawbacks of the RB process. In the present study, Pb particles were used to enhance the bond strength between aluminum strips as filler material. AA1050 particle-reinforced sheets with different contents of interlayer Pb particles were fabricated at various rolling temperatures and thickness reduction ratios. Effects of roll bonding parameters that create successful bonds such as amount of Pb particle content, plastic strain from rolling process and rolling temperature were investigated. The bond strength was evaluated by the peeling test. It was found that by increasing the rolling temperature, thickness reduction ratio and Pb content, successful bonds with higher strength were created. Scanning electron microscopy was utilized to characterize the peeled surface of AA1050/Pb samples.

Authors: Cvetković Marija , Dinkić Nikola , Djukić Aleksandra , Joković Jugoslav
Published: January 2018

This paper explores the built environment of a shopping mall and considers the perceptions of its users, measuring the intensity of users both in open public spaces and shopping malls. This paper aims to compare the concentration of users in the selected shopping malls built in New Belgrade and open public spaces in the city centre. It considers the preferences consumers have towards shopping malls and public spaces, by determining their opinion on the (dis)advantages of the shopping malls over features of the city centre. The methodological frameworks of the research are questionnaires, surveys and a method of mapping users on social maps (via social networks). The identity of shopping malls versus public places in Belgrade is observed through technical analyses and qualitative surveys using online and on-site questionnaires, as well as the study of social media (twitter). A structured questionnaire was developed to measure customers’ shopping motivation, preferences, as well as the demographic information of respondents, questions about the identity of the shopping mall and the city centre, and the connection between them. The research also used the newly developed software application - Twitter search engine. The aim was tracking and measuring the intensity of users in the monitored territory, and testing their latest behavioural patterns. Summarizing and interpreting the collected data provided three groups of results: competitiveness of the shopping mall with open public space with the focus on the main qualities; measuring the concentration of users both in shopping malls and open public spaces, and suggestions for improvement of open public spaces.

Authors: Begum Shamim MF , Sultana Nasreen , Jabin Zeenat , Parveen Rahima , Sarker Azmal Kabir , Banu Layla Saroware
Published: January 2018

Osteoporosis and scoliosis are encountered concurrently. Scoliosis predisposes to osteoporosis but degenerative scoliosis could falsely elevate lumbar bone mineral density measurement leading to discordance. This study was conducted to determine the prevalence of discordance between lumbar spines and hip bone mineral density in patients with lumbar scoliosis and to evaluate the risk factors of discordance. The prevalence of osteoporosis and discordance was determined as major and minor discordance. Old age, age at menopause, sex and BMI were considered as possible risk factors for discordance and were used in multivariate logistic regression analysis.   Discordance between lumbar spines and hip was found in 55 (78.6 %) patients and among them major and minor discordance of T-scores were seen in 18 (25.7%) and 37 (52.9%) respectively. Concordance of T scores was seen in 15 (21.4%). In multivariate logistic regression analysis female sex, age older than 60 years and BMI less than 30 kg/m2 was identified as risk factors for T-score discordance.In lumbar scoliosis the overestimation of lumbar spine may lead to diagnostic dilemma, whereas hip DEXA appears to be more reliable in these cases. In such cases it is in the jurisdiction of the physician to look for possible underlying causes of discordance of T score.Bangladesh J. Nuclear Med. 18(2): 121-124, July 2015

Published: January 2018

A rapid, accurate, precise, stability indicating and enantioselective chiral HPLC method was developed and validated for the quantitative (S)- and (R)- omeprazole in omeprazole formulations along with determination of enantiomeric purity of (S)- omeprazole in esomeprazole formulations according to the guidelines of the United States of Pharmacopeia (USP) and International Conference on Harmonization (ICH). The chromatographic separation was achieved with n-hexane/ 2-propanol/ acetic acid/ triethylamine (100 : 20 : 0.2 : 0.1, v/v) at a flow rate of 1.2 ml/min on Chiralcel OD-H and detected at 300 nm. The method showed good linearity, high sensitivity with detection limit (LOD) of 0.71 and 1.16 μg/ml and quantitation limit (LOQ) of 2.16 and 3.51 μg/ml for (S)- and (R)- omeprazole, respectively. The average percentage of recovery was found to be 100.85% to 101.36% for (S)- and 99.81% to 101.62% for (R)- omeprazole. The average percentage of relative standard deviation (% RSD) for intra- and inter- day precision were found to be 0.05% and 0.19% for (S)- and 0.03% and 0.13% for (R)- omeprazole, respectively. Stability study was performed under stress conditions. Microthermal analysis of omeprazole was also performed by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM) to assess the physical and chemical behavior of the drug. The method was successfully applied to the quantitation of (S)- and (R)- omeprazole for omeprazole and as well as determination of (S)- omeprazole purity for esomeprazole formulations.Dhaka Univ. J.

Published: January 2018

The study was aimed to characterize bacterial isolates from respiratory tract infections (RTI) and   investigate their antibiotic sensitivity profile. Selective media and biochemical tests were used to characterize 40   bacterial isolates. Antibiotic sensitivity testing was conducted using Kirby-Bauer disc diffusion method. About   42.5% (17) RTI patients were infected by Klebsiella pneumoniae, 30% (12) by Escherichia coli and 27.5% (11) by   Pseudomonas aeruginosa with no significant gender variation (p-value <0.578). Overall, 47% (out of 20) antibiotics   were sensitive, whereas 48% were resistant. Surprisingly, 18% P. aeruginosa and 20% K. pneumoniae were   carbapenem-resistant and 4 out of 7 cephalosporin antibiotics were highly resistant irrespective of pathogens. E. coli   showed better sensitivity to nitrofurantoin (78%) and levofloxacin (89%), while K. pneumoniae was insensitive to   cotrimoxazole (88%), gentamycin (77%) and piperacillin/tazobactam (66%). On the other hand, P. aeruginosa did   not respond to P. aeruginosa to nalidixic acid (60%) and ciprofloxacin (60%). This study concludes that   nitrofurantoin, levofloxacin, cotrimoxazole, gentamycin and piperacillin/tazobactam antibiotics could be better   alternative in treating bacterial RTIs.Dhaka Univ. J.

Synthesis and Application of Cerium-Incorporated SBA-16 Supported Ni-Based Oxygen Carrier in Cyclic Chemical Looping Steam Methane Reforming

Published: January 2018

Hydrogen, as a clean energy carrier, could be produced aided by cyclic oxidation-reduction of oxygen carriers (OCs) in contact with carbonaceous fuel in chemical looping steam methane reforming (CL-SMR) process. In this study, the cerium was incorporated into the SBA-16 support structure to synthesize the Ni/Ce-SBA-16 OC. The supports were synthesized using hydrothermal method followed by impregnation of Ni and characterized via low and wide angle X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM), coupled with energy dispersive X-ray (EDX) spectroscopy, and transmission electron micrograph (TEM) techniques. In addition, the effect of various Si/Ce molar ratios (20–60) in the support structure, Ni loading (10–30 wt %), reaction temperature (500–750 °C), and life time of optimal oxygen carrier over 16 cycles were investigated. The results of wide angle XRD and SEM revealed that the incorporation of CeO2 in the channels of SBA-16 caused the formation of nickel metallic particles with smaller size and prevents the coke formation. The results showed that OC with 15 wt % Ni and Si/Ce molar ratio of 40 (15Ni/Ce-SBA-16(40)) has the best performance when compared with other OCs in terms of catalytic activity and structural properties. The methane conversion of about 99.7% was achieved at 700 °C using 15Ni/Ce-SBA-16(40) OC. We anticipate that the strategy can be extended to investigate a variety of novel modified mesoporous silica as the supporting material for the Ni based OCs.

Classical-Equivalent Bayesian Portfolio Optimization for Electricity Generation Planning
Authors: Takada Hellinton , Stern Julio , Costa Oswaldo , Ribeiro Celma
Published: January 2018

There are several electricity generation technologies based on different sources such as wind, biomass, gas, coal, and so on. The consideration of the uncertainties associated with the future costs of such technologies is crucial for planning purposes. In the literature, the allocation of resources in the available technologies has been solved as a mean-variance optimization problem assuming knowledge of the expected values and the covariance matrix of the costs. However, in practice, they are not exactly known parameters. Consequently, the obtained optimal allocations from the mean-variance optimization are not robust to possible estimation errors of such parameters. Additionally, it is usual to have electricity generation technology specialists participating in the planning processes and, obviously, the consideration of useful prior information based on their previous experience is of utmost importance. The Bayesian models consider not only the uncertainty in the parameters, but also the prior information from the specialists. In this paper, we introduce the classical-equivalent Bayesian mean-variance optimization to solve the electricity generation planning problem using both improper and proper prior distributions for the parameters. In order to illustrate our approach, we present an application comparing the classical-equivalent Bayesian with the naive mean-variance optimal portfolios.

Authors: Benato Roberto , Balanuye İbrahim , Köksal Fatih , Ozan Nurhan , Özdemirci Ercüment
Published: January 2018

This paper describes the 400 kV AC submarine link under the Dardanelles Strait composed of 12 submarine armoured single-core cross-linked polyethylene (XLPE)-insulated cables (plus a back-up power cable). The link consists of two parallel-operated double-circuit links named Lâpseki–Sütlüce I and Lâpseki–Sütlüce II. The transmissible power is 4000 MW (1000 MW per circuit) and the average length for a single-core cable is about 4.6 km: the submarine cables are part of overhead lines. This paper gives a wide account of the cable installations and, chiefly, of the cable protections on the seabed: different protection choices were extensively used (i.e., water jetting and mattressing).

STI Knowledge in Berlin Adolescents
Authors: Von Rosen Frederik , Von Rosen Antonella , Müller-Riemenschneider Falk , Damberg Inken , Tinnemann Peter
Published: January 2018

Sexually transmitted infections (STIs) pose a significant threat to individual and public health. They disproportionately affect adolescents and young adults. In a cross-sectional study, we assessed self-rated and factual STI knowledge in a sample of 9th graders in 13 secondary schools in Berlin, Germany. Differences by age, gender, migrant background, and school type were quantified using bivariate and multivariable analyses. A total of 1177 students in 61 classes participated. The mean age was 14.6 (SD = 0.7), 47.5% were female, and 52.9% had at least one immigrant parent. Knowledge of human immunodeficiency virus (HIV) was widespread, but other STIs were less known. For example, 46.2% had never heard of chlamydia, 10.8% knew of the HPV vaccination, and only 2.2% were aware that no cure exists for HPV infection. While boys were more likely to describe their knowledge as good, there was no general gender superiority in factual knowledge. Children of immigrants and students in the least academic schools had lower knowledge overall. Our results show that despite their particular risk to contract an STI, adolescents suffer from suboptimal levels of knowledge on STIs beyond HIV. Urgent efforts needed to improve adolescent STI knowledge in order to improve the uptake of primary and secondary prevention.
