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.

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

<p>The Markoff equation x<sup>2</sup> + y<sup>2</sup> + z<sup>2</sup> = 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 x<sup>2</sup> + y<sup>2</sup> + z<sup>2</sup> = 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 x<sup>2</sup> + y<sup>2</sup> + z<sup>2</sup> =3xyz + A where A is positive integer with A ≤ 4(x<sup>2</sup> –1) is given. </p><p><strong>Journal of Advanced College of Engineering and Management,</strong> Vol. 3, 2017, Page : 137-145</p>
Significant enhancement of bond strength in the roll bonding process using Pb particles
Authors: Vini Mohammad Heydari , Zadeh Omid Hossein 
Published: January 2018

Abstract
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.

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

Authors: Promite Shukla , Saha Sajal K , Ahsan Sunjukta , Akhter Marufa Zerin 
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. Pharm.

Effect of Limb Position at the Time of Skin Marker Application on Sagittal Plane Kinematics of the Dog
Authors: Kim Sun-Young , Torres Bryan , Sandberg Gabriella , Budsberg Steven 
Published: January 2018

Abstract
Objectives To evaluate the effect of limb position during initial skin marker application on sagittal plane kinematics of the hindlimb.
Methods Six healthy dogs (20–30 kg) were evaluated. An established two-dimensional kinematic model of the pelvic limb was utilized to describe sagittal plane motion. Kinematic markers were applied separately for each dog while standing in three different positions: (1) the limb extended cranially, (2) a normal standing limb position and (3) the limb extended caudally. Following marker application at each of the three positions, dynamic gait was recorded at a walk (velocity, 0.9–1.2 m/s; acceleration, 0.5m/s2). Five valid trials were used for comparison. Complete waveform analysis was performed with generalized indicator function analysis (GIFA). Maximum and minimum joint angles and joint range of motion were compared with a one-way repeated measures ANOVA with significance at p < 0.05.
Results Significant differences were found between stifle waveforms. No differences were found between the hip or tarsus waveforms. Minimum and maximum joint angles were significantly different for the hip and stifle but not for the tarsus. No differences were found between ranges of motion for any joint evaluated.
Clinical Significance Limb position at the time of skin marker application affects gait data and is an important consideration for kinematic analysis of the hindlimb in dogs.

Published: January 2018

Abstract
Objectives This study aims to quantify numbers of elastic fibres in cranial cruciate ligaments from a dog breed at high risk of cranial cruciate ligament disease.
Methods Macroscopically normal cranial cruciate ligaments were harvested from six Labrador retrievers. Sequential histological sections were assessed for extracellular matrix degeneration (haematoxylin and eosin stain) and elastic fibre staining (Miller’s stain). Elastic fibres were semi-quantified using previously published scoring systems. Each section was scored twice by two observers.
Results Increased numbers of elastic fibres were seen with increasing cranial cruciate ligament degeneration (p = 0.001). Labrador retriever cranial cruciate ligaments had lower elastic fibre staining when compared with previous published findings in the racing greyhound.
Clinical Significance The cranial cruciate ligaments from a dog breed at high risk of cranial cruciate ligament disease vary in the quantity of elastic fibres in association with ligament degeneration. Breed variation in the quantity of elastic fibres may reflect differing risk of cranial cruciate ligament disease.
The Taurus Boundary of Stellar/Substellar (TBOSS) Survey. II. Disk Masses from ALMA Continuum Observations

Published: January 2018

Abstract
We report 885 μm ALMA continuum flux densities for 24 Taurus members spanning the stellar/substellar boundary with spectral types from M4 to M7.75. Of the 24 systems, 22 are detected at levels ranging from 1.0 to 55.7 mJy. The two nondetections are transition disks, though other transition disks in the sample are detected. Converting ALMA continuum measurements to masses using standard scaling laws and radiative transfer modeling yields dust mass estimates ranging from ∼0.3 to 20 M
⊕. The dust mass shows a declining trend with central object mass when combined with results from submillimeter surveys of more massive Taurus members. The substellar disks appear as part of a continuous sequence and not a distinct population. Compared to older Upper Sco members with similar masses across the substellar limit, the Taurus disks are brighter and more massive. Both Taurus and Upper Sco populations are consistent with an approximately linear relationship in M
dust to M
star, although derived power-law slopes depend strongly upon choices of stellar evolutionary model and dust temperature relation. The median disk around early-M stars in Taurus contains a comparable amount of mass in small solids as the average amount of heavy elements in Kepler planetary systems on short-period orbits around M-dwarf stars, with an order of magnitude spread in disk dust mass about the median value. Assuming a gas-to-dust ratio of 100:1, only a small number of low-mass stars and brown dwarfs have a total disk mass amenable to giant planet formation, consistent with the low frequency of giant planets orbiting M dwarfs.
Cosmic Microwave Background Mapmaking with a Messenger Field
Authors: Huffenberger Kevin M. , Næss Sigurd K. 
Published: January 2018

Abstract
We apply a messenger field method to solve the linear minimum-variance mapmaking equation in the context of Cosmic Microwave Background (CMB) observations. In simulations, the method produces sky maps that converge significantly faster than those from a conjugate gradient descent algorithm with a diagonal preconditioner, even though the computational cost per iteration is similar. The messenger method recovers large scales in the map better than conjugate gradient descent, and yields a lower overall χ
2. In the single, pencil beam approximation, each iteration of the messenger mapmaking procedure produces an unbiased map, and the iterations become more optimal as they proceed. A variant of the method can handle differential data or perform deconvolution mapmaking. The messenger method requires no preconditioner, but a high-quality solution needs a cooling parameter to control the convergence. We study the convergence properties of this new method and discuss how the algorithm is feasible for the large data sets of current and future CMB experiments.

Abstract
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) provides spectroscopic information of regions of the inner Milky Way, which are inaccessible to optical surveys. We present the first large study of the metallicity distribution of the innermost Galactic regions based on high-quality measurements for 7545 red giant stars within 4.5 kpc of the Galactic center, with the goal to shed light on the structure and origin of the Galactic bulge. Stellar metallicities are found, through multiple Gaussian decompositions, to be distributed in several components, which is indicative of the presence of various stellar populations such as the bar or the thin and the thick disks. Super-solar ([Fe/H] = +0.32) and solar ([Fe/H] = +0.00) metallicity components, tentatively associated with the thin disk and the Galactic bar, respectively, seem to be major contributors near the midplane. A solar-metallicity component extends outwards in the midplane but is not observed in the innermost regions. The central regions (within 3 kpc of the Galactic center) reveal, on the other hand, the presence of a significant metal-poor population ([Fe/H] = −0.46), tentatively associated with the thick disk, which becomes the dominant component far from the midplane (

kpc). Varying contributions from these different components produce a transition region at +0.5 kpc

, characterized by a significant vertical metallicity gradient.
Circumnuclear Multi-phase Gas in the Circinus Galaxy. I. Non-LTE Calculations of CO Lines

Published: January 2018

Abstract
In this study, we investigate the line emissions from cold molecular gas based on our previous “radiation-driven fountain model,” which reliably explains the spectral energy distribution of the nearest type 2 Seyfert galaxy, the Circinus galaxy. Using a snapshot of the best-fit radiation-hydrodynamic model for the central

pc, in which non-equilibrium X-ray-dominated region chemistry is solved, we conduct post-processed non-local thermodynamic equilibrium radiation transfer simulations for the CO lines. We obtain a spectral line energy distribution with a peak around

and

), which can be directly obtained from the results and is not a constant, depends strongly on the integrated intensity and differs from the fiducial value for local objects.

exhibits a large dispersion of more than one order of magnitude, reflecting the non-uniform internal structure of a “torus.” In addition, we found that the physical conditions differ between grid cells on a scale of a few parsecs along the observed lines of sight; therefore, a specific observed line ratio does not necessarily represent a single physical state of the interstellar medium.
