Un modelo de finca integrada orientada a contribuir a la seguridad alimentaria de comunidades indígenas de Talamanca (Artículo informativo)
Authors: Salazar-Díaz Ricardo
Published: November 2015

Este proyecto se lleva a cabo en el marco del Programa de Regionalización Interuniversitaria dentro de la iniciativa denominada Fortalecimiento de los sistemas de producción y comercialización de las unidades productivas y de servicios indígenas respetando la cultura Bribri y Cabécar con un enfoque ambientalmente sostenible. El proyecto consiste en un modelo de finca integrada orgánica, orientada a contribuir a la seguridad alimentaria y al fortalecimiento agroecológico y cultural de comunidades indígenas de Talamanca. 

El proyecto es liderado por tres jóvenes hermanos de la comunidad de Shuabb, distrito Telire, cantón de Talamanca, Costa Rica. En un área de cuatro hectáreas se estableció un modelo de producción agropecuaria, que consiste básicamente en la diversificación productiva de cultivos agrícolas, forestales y pecuarios de especies menores. 

Más de 20 diferentes especies cultivadas, entre raíces, tubérculos, granos básicos, vegetales, hortalizas, frutales y forestales; módulos de gallinas y cerdos en pastoreo y dos estanques de peces hacen de esta finca familiar un modelo alternativo de desarrollo socioeconómico, que contribuye al autoconsumo y fomenta el mercado local. 

A pesar de que los sistemas agrícolas tradicionales talamanqueños provienen de la relación continua y equilibrada con su medio natural, existe una evidencia del deterioro de esta relación. Como un resultado de esta iniciativa, se pretende que esta propuesta de sistema productivo sea un modelo a replicar en comunidades vecinas y de esta manera contribuir al desarrollo humano sostenible de la región de Talamanca.

Published: November 2015

En el presente trabajo, experimentalmente se demuestra que las valoraciones potenciométricas usuales en química analítica (acido-base, redox, complejométricas y de halogenuros) pueden llevarse a cabo utilizando como sistema indicador de punto de equivalencia, un multímetro en vez del potenciómetro, mediante la prueba estadística de t de Student; y se posibilita con esto que los laboratorios de docencia se puedan equipar mejor y a bajo costo, con multímetros en vez de potenciómetros.

Published: November 2015

El Caribe costarricense es importante como sitio de alimentación, copulación, anidación y desove de las tortugas marinas, por lo que el presente trabajo pretendió actualizar el patrón de anidación en las tortugas marinas Dermochelys coriacea y Eretmochelys imbricata en el sector Gandoca, del Refugio Nacional de Vida Silvestre Gandoca Manzanillo, Limón, Costa Rica, para proponer medidas de manejo. Se realizaron recorridos nocturnos entre las 8:00 p. m. y 4:00 a. m., la playa se dividió en cinco sectores, en estos se realizaron observaciones directas y de rastros, de las tortugas que elaboraron el nido, entre febrero y agosto del 2011 y 2012. Se registraron tres especies de tortugas marinas, Dermochelys coriacea, Eretmochelys imbricata y Chelonia mydas. La anidación de tortugas baula tuvo su punto máximo entre marzo y julio; por su parte, las carey, entre mayo y junio (2011), y junio hasta agosto en el 2012. Se observó preferencia en la posición de la playa utilizada para construir sus nidos; la baula utiliza principalmente la parte media, mientras que la carey utilizó mayormente la parte baja para anidar (t = 17.2525). Se observó que la baula utilizó frecuentemente el sector C; sin embargo, no se encontraron diferencias en el uso de los sectores. Se concluye que ambas especies tienen preferencias en la selección de la zona de playa en que anidan; la carey en la parte baja cerca de la línea de costa y la baula en la parte media. Además, las tortugas baula utilizan indistintamente los diferentes sectores de la playa estudiada.

Authors: Karadzic Jelena , Kovacevic Igor , Ljikar Jelena , Grgic Zorka , Devecerski Gordana
Published: November 2015

Introduction. Macular edema is the main cause of visual loss in patients with
branch retinal vein occlusion. Macular edema is initially reversible, but
over time, permanent loss of vision occurs from structural damage to the
macula. For this reason, there is a need for more rapid and effective
treatments than laser photocoagulation which has been established as a gold
standard. There are several pharmacologic agents which have changed the
management of macular edema. Material and Methods. Twenty eyes of 20
consecutive patients of the Department of Eye Diseases, Clinical Center of
Vojvodina, in Novi Sad, were enrolled in this prospective, randomized and
consecutive study conducted from January 2012 to January 2013. The patients
were randomly assigned into two treatment groups, and they were given an
intravitreal injection of bevacizumab 1.25 mg/0.05 mL (Avastin?), or
triamcinolone acetonid injection 4 mg/0.1mL (Kenalog?). Reinjections were
performed according to the following retreatment criteria a loss of visual
acuity or increase in central retinal thickness. Results. Both intravitreal
bevacizumab and triamcinolonacetonid were very effective in reducing macular
edema and improving visual acuity in the eyes with macular edema secondary to
retinal vein occlusion. The effect of the treatment was more pronounced if it
started early after the onset of macular edema. The reported temporary
effects of intravitreal triamcinolon- acetonide and bevacizumab could be
explained by their clearance from the eye. Conclusion. The short-term results
of our clinical trial showed that pharmacological intravitreal agents, such
as bevacizumab and triamcinolon-acetonid, lead to rapid resolution of macular
edema and significant improvement of visual acuity.

Authors: Brdaric Dragana , Jovanovic Veljko , Gavrilov-Jerkovic Vesna
Published: November 2015

Introduction. Excess bodyweight and obesity are widespread health problems
throughout the world. In Serbia, over 50% of the adult population is
overweight and the Province of Vojvodina is one of the regions with the
highest percentage of obesity. The relationship between obesity and health
complications has been consistently demonstrated. However, research on the
relationship between obesity and subjective well-being has not provided clear
results. Body dissatisfaction is considered to be an important factor for
understanding this relationship. The main objective of this study was to
investigate the moderating effect of body dissatisfaction in the relationship
between body mass index and subjective well-being. Material and Methods. The
study sample included 731 respondents (72.6% women), with the mean age 28.93
years (SD = 8.47) from the Province of Vojvodina who had completed an online
set of tests consisting of Body Shape Questionnaire, Depression Anxiety
Stress Scale-21, Satisfaction with Life Scale, Scale of Positive and Negative
Experience and a self-assessment of bodyweight and body height. Results. The
results indicate that the moderating effect of body dissatisfaction in the
relationship between body mass index and indicators of subjective well-being
is statistically significant in both sexes. Specifically, the women with
higher body mass index values who expressed lower body dissatisfaction
reported lower levels of emotional distress and higher levels of pleasant
emotions than those with lower body mass index. On the other hand, the men
with higher bodyweight preoccupation and low body mass index reported
significantly higher levels of pleasant emotions than those with higher body
mass index values. Conclusion. These results suggest the necessity of a more
detailed study of this relationship on both clinical and general population
samples from Serbia.

Authors: Stosic Maja , Lazarevic Natasa , Kuruc Vesna , Ristic Lidija
Published: November 2015

Introduction. At the onset of the 21st century, tuberculosis is still a
public health problem. Due to the implementation of tuberculosis control
program in Serbia, there is no fear of an epidemic. Within the reform of the
health care system, the service for pulmonary diseases is being restructured,
calling for strengthening the role of primary health care. This study was
aimed at analyzing the current role of primary health care in tuberculosis
control. Material and Methods. A cross-sectional study was conducted between
the 12th and 30th September, 2010. For evaluating the current role of primary
health care in tuberculosis control, four questionnaires were designed based
on the ?Performance assessment questionnaire regarding TB control for use in
PHC?, Journal Brasileiro de Pneumologia, print version ISSN 1806-3713 (vol.
35, no 6, Sao Paulo, June 2009). The following methods were used to analyze
the results: descriptive statistical analysis, Student?s T-test, Fisher?s
analysis of variance. The reliability of the results was tested with
Cronbach?s alpha and factor analysis. The level of significance in all the
methods bordered 0.05. Results. Primary health care does not participate in
tuberculosis control in line with the possibilities of the existing legal
framework. Although the paper proves that tuberculosis notification rate is
higher in the areas less covered by the pneumophysiological service, the role
of primary health care does not differ from the areas fully covered.
Conclusion. There is a need for strategic empowerment of the primary health
care system to be actively involved in the diagnostics, treatment and follow
up of tuberculosis in Serbia.

Introduction. Osteoporosis is the most frequent metabolic disease of bones.
Early detection of pathological loss of bone mineral density represents the
first step in prevention, treatment and rehabilitation of osteoporosis. This
study was aimed at establishing the correlation of T-score values obtained by
ultrasound osteodensitometry of calcaneus with dual-energy x-ray
absorptiometry scan. Material and Methods. The study was conducted on the
sample of 569 female patients from September 13, 2010 to March 10, 2011.
Measurement was made with ultrasound osteodensitometry of ACHILLES make.
Quantitative ultrasound method revealed that 77 female patients had a lower
value of T-score (osteopenia with risk factors or osteoporosis) and they were
referred to T-score measurement with dual-energy x-ray absorptiometry scan.
Dual-energy x-ray absorptiometry scanning was performed using LUNAR DPX
scanner and 49 female patients were examined. Results. It was concluded that
there was no statistically significant difference between T-score values
obtained by quantitative ultrasound and dual-energy x-ray absorptiometry
scanning. Conclusion. According to this study, it is necessary to provide a
greater number of scanners for ultrasound osteodensitometry of calcaneus in
order to secure prevention and to refer the patients to further diagnosing on
time.

Published: November 2015

History of marital infertility is as long as the history of human
civilization. Becoming aware about the importance of procreation, as well as
the problems with which people may confront, has been the subject of interest
since the moment of the first human community creation. Historically, each
stage of social development, hence the development of science, has carried
within itself certain findings more or less acceptable from today?s point of
view. The development of human awareness and acquisition of findings based on
empirical evidence have contributed to understanding and solution of the
problem which was considered to be a result of force majeure until that
moment and therefore could not be influenced. This paper deals with the
previously mentioned issues through the review of historical development of
assisted reproductive technology and its importance. The authors? intention
was to present the developmental road of assisted reproductive technology
through history succinctly with a special emphasis on the moments which have
been of the crucial importance and which have marked certain stages of its
development.

Generalization of Helmholtz coil problem
Authors: Petkovic Dejan , Radic Milica
Published: November 2015

The primary intent of this work is to propose a simple analytical method for
designing coil systems for homogeneous and gradient magnetostatic field
generation. Coil system consists of two identical coaxial (regular) polygonal
current loops. In the space between the loops, there is nearly homogeneous or
nearly linear distribution of the magnetic field along the axes depending on
the currents' direction. First, we derived a suitable, simple and general
expression for the magnetic field along the axes due to a polygonal current
loop. We emphasize the importance of the role of this expression for further
analysis. The total on-axes magnetic field is the result of superposition of
the magnetic fields that each loop generates separately. The proper distance
between the loops and the current orientation make the system to become
either Helmholtz coil or anti-Helmholtz coil. In this paper we give exact,
analytical and general expression for this optimal distance that provides the
magnetic field to be homogeneous (linear) as much as possible. We based our
study on Taylor series expansion of the total magnetic field, demanding that
the first contaminating term must be canceled, in both, symmetric and
asymmetric case.

Numerical prediction of cavitating flow around a hydrofoil using pans and improved shear stress transport k-omega model
Authors: Zhang De-Sheng , Pan Da-Zhi , Wang Hai-Yu , Shi Wei-Dong
Published: November 2015

The prediction accuracies of partially-averaged Navier-Stokes model and
improved shear stress transport k-? turbulence model for simulating the
unsteady cavitating flow around the hydrofoil were discussed in this paper.
Numerical results show that the two turbulence models can effectively
reproduce the cavitation evolution process. The numerical prediction for the
cycle time of cavitation inception, development, detachment, and collapse
agrees well with the experimental data. It is found that the vortex pair
induced by the interaction between the re-entrant jet and mainstream is

Published: November 2015

The unsteady cavitating flow and pressure fluctuation around the 3-D NACA66
hydrofoil were simulated and validated based on detached eddy simulation
turbulence model and a homogeneous cavitation model. Numerical results show
that detached eddy simulation can predict the evolution of cavity inception,
sheet cavitation growth, cloud cavitation shedding, and breakup, as well as
the pressure fluctuation on the surface of hydrofoil. The sheet cavitation
growth, detachment, cloud cavitation shedding are responsible for the

achieve homeostasis. Compared with random graph, the biochemical reaction
network has larger information capacity and is more efficient in information
transmission. This is consistent with theory of evolution.

Effects of supercritical carbon dioxide on morphology of apocynum venetum fibers
Authors: Gao Shi-Hui , Yu Chong-Wen
Published: November 2015

This paper investigated the structures and compositions of apocynum venetum
fibers treated with pectinase and mixture of sodium hydroxide and hydrogen
peroxide in supercritical carbon dioxide fluid. The apocynum venetum fibers
were analyzed by Fourier transform infrared spectrometry, X-ray diffraction,
and scanning electron microscopy. Fourier transform infrared analysis
indicated that pectinase could remove the pectin and hemicellulose and the
mixture of sodium hydroxide and hydrogen peroxide could extract the lignin in
supercritical carbon dioxide. Meanwhile, the results of X-ray diffraction
showed that cellulose crystallinity index and crystallite sizes of treated
fibers increased in comparison with that of untreated fibers. The studies of
scanning electron microscopy also revealed a complete removal of
non-cellulosic gummy material from surface of treated apocynum venetum
fibers. Small gummy on the surface of apocynum venetum fibers would be
removed by supercritical carbon dioxide, which can be verified by bubble
dynamics.

Boundary effect on liquid invasion in tight gas reservoirs
Authors: Li Gao , Ren Wen-Xi , Meng Ying-Feng , Yi Feng , Sun Ai-Sheng , Chu Heng-Zhi
Published: November 2015

Liquid invasion is an important transport phenomenon in many geophysical and
environmental applications. A new capillary model considering boundary effect
is proposed to reveal its mechanism. The boundary fluid layer not only
reduces the effective flow radius, but also changes the viscosity of fluid.
Thus the capillary force and viscosity resistance increases, however, the
increase of capillary force is faster than that of viscosity resistance,
therefore the invasion front arrives at the critical distance earlier.
Comparison of heat transfer efficiency between heat pipe and tube bundles heat exchanger
Authors: Wu Zhao-Chun , Zhu Xiang-Ping
Published: November 2015

A comparison of heat transfer efficiency between the heat pipe and tube
bundles heat exchanger is made based on heat transfer principle and the
analysis of thermal characteristics. This paper argues that although heat
pipe has the feature of high axial thermal conductivity, to those cases where
this special function of heat transfer is unnecessary, heat pipe exchanger is
not a high efficient heat exchanger when it is just used as a conventional
heat exchanger in the industrial fields. In turn, there are some deficiencies
for heat pipe exchanger, such as complicated manufacturing process, critical
requirements for manufacturing materials, etc. which leads to a higher cost
in comparison to a tubular heat exchanger. Nonetheless, due to its diverse
structural features and extraordinary properties, heat pipe exchanger still
has wide applications on special occasions.

Numerical approach to the top coal caving process under different coal seam thicknesses
Authors: Yu Bin , Zhang Ru , Gao Ming-Zhong , Li Guo , Zhang Ze-Tian , Liu Qian-Ying
Published: November 2015

Numerical study of mining-induced stress evolution of coal during the top
coal caving process under different coal seam thicknesses is carried out, and
the numerical prediction agrees well with the field test data. Main
characters on stress distribution and dangerous area are elucidated. For the
same coal quality, coal layers under 7 m thick fail earlier than thicker coal
layers; correspondingly, the internal fracture networks of thin layers are
more easily developed. During the mining of a coal layer less than 7 m thick,
stress monitoring of the ?dangerous area? in the middle of the top coal
should be emphasized, whereas during the mining of coal layers less than 11 m
thick, stress monitoring of the ?dangerous area? at the bottom of the top
coal should be highlighted. The research is to optimize caving technique and
extraction process.

Transverse vibration of an axially moving slender fiber of viscoelastic fluid
is studied. The governing equations are derived under the assumptions of
onedimensional steady and incompressible flow and linear Euler-Bernoulli
bar. Effect of the moving velocity of the liquid fiber on natural
frequencies is discussed, and the critical velocities of moving fibers are
derived, below which transverse vibration is exponentially damped.

Published: November 2015

Bubbfil spinning is used to fabricate micro/nanofibers with hierarchical
structure. The wall of a polymer film is attenuated unevenly by a blowing
air. The burst of the bubble results in film fragments with different
thickness, as a result, different sizes of fibers are obtained.
Effects of the conduit geometry on the air flow field in the spunbonding process
Authors: Wu Li-Li , Sun Hong-Mei , Chen Ting
Published: November 2015

In the spunbonding process, the air flow field of the drawing conduit affects
the polymer drawing and therefore the filament diameter greatly. Effects of
the conduit parameters on the air flow field are studied using the previously
established air flow field model. The results show that longer narrow
section, longer contracting section and larger height of narrow entry are of
benefit to increasing the air velocity, thus helpful for decreasing the
filament diameter.

Published: November 2015

In February 2015, an outbreak of recently acquired HIV infections among people who inject drugs (PWID) was identified in Dublin, following similar outbreaks in Greece and Romania in 2011. We compared drug and risk behaviours among 15 HIV cases and 39 controls. Injecting a synthetic cathinone, snow blow, was associated with recent HIV infection (AOR: 49; p = 0.003). Prevention and control efforts are underway among PWID in Dublin, but may also be needed elsewhere in Europe.

Published: November 2015

Increased febrile reactions in Australian children from one influenza vaccine brand in 2010 diminished confidence in influenza immunisation, highlighting the need for improved vaccine safety surveillance. AusVaxSafety, a national vaccine safety surveillance system collected adverse events in young children for 2015 influenza vaccine brands in real time through parent/carer reports via SMS/email. Weekly cumulative data on 3,340 children demonstrated low rates of fever (4.4%) and medical attendance (1.1%). Fever was more frequent with concomitant vaccination.

Authors: Rajkumar Kalyan , Radera Shruti , Agarwal Jyotsna , Singh Mastan
Published: November 2015

Aims and Objectives: Increase in the incidence of Escherichia coli and Klebsiella pneumoniae carrying New Delhi metallo beta lactamase-1 (NDM-1) gene are called superbugs is of great concern as presence of blaNDM-1 gene makes E.coli and K.pneumoniae highly resistant to most of currently available antibiotics. This study was planned to observe the burden of blaNDM-1 gene carrying E. coli and K.pneumoniae at a tertiary care hospital in northern India. Materials and Methods: A total of 1709 E. coli and 327 K. pneumonia nonrepitive isolates were taken from various clinical samples received in a tertiary care hospital in northern India Lucknow during the period from May 2012 to April 2013. Carbapenemase production was phenotypically detected in all the carbapenem resistant isolates by modified Hodge test. Metallo-β-lactamase production was detected by using meropenem and imipenem discs with and without EDTA and blaNDM-1 gene was detected by polymerase chain reaction. Results: Over all metallo β- lactamase production was found in 82% and 88.89% of carbapenem resistant E.coli and K. pneumonia respectively. Out of 366 carbapenem resistant isolates, 102 were found positive for blaNDM-1 gene out of which 89 were E.coli and 13 were K. pneumoniae. Conclusions: With limited treatment options left for this crisis situation like the pre-antibiotic era; it is an alarm for rational antibiotic therapy usage and intensive education programs.Asian Journal of Medical Sciences Vol.7(2) 2015 76-79

Published: November 2015

Aims and Objectives: To assess the effect of Cobb angle and body mass index (BMI) on surgery recovery outcomes in Adolescent Idiopathic Scoliosis (AIS) patients.Materials and Methods: A retrospective study of 79 Adolescent Idiopathic Scoliosis patients who underwent corrective operations, at King Khaled University Hospital, Riyadh, Saudi Arabia was carried out in 2014. The patients were divided according into Cobb’s angle (mild, moderate and severe) and as per weight (healthy weight and overweight). Data of preoperative, intra-operative and postoperative information as well as measures of daily-living activities were collected.Results: The mean age of 79 patients (70females) was 16.6 years. Cobb angle assessment was mild in 41 (51.9%), moderate in 24(30.4%) and 14(17.7%) were severe. Mean surgery and recovery time of patients is statistically significantly different in relation to severity of Cobb’s angle (mild, moderate and severe). There is highly statistically significant difference in mean ranks of days taken for different measures of daily living in relation to severity of Cobb’s angle. The mean values of body mass index have significantly reduced after surgery, when compared with mean values at before surgery. The mean surgery time was statistically significantly higher in over weight patients (5.33 hours).Conclusions: The results show an effect of severity of Cobb angle on recovery measures of patients with AIS, but no effect of BMI. BMI was corrected in these patients after surgery. Prospective studies are required to assess clinical outcomes of post-operative surgery, satisfaction of patients towards their body image and quality of life.Asian Journal of Medical Sciences Vol.7(2) 2015 28-33

Authors: Rohil Vishwajeet , Rahman Mujeeb Ur , Beetan Neetu , Sharma Anju , Sharma Karuna , Kumar Ajit
Published: November 2015

Objective: Role of Polyphenolic acetates (PAs) was studied to explore their ability to impart acetylation of histone protein by the novel mechanism of acetylation in Ehrlich Ascites tumour (EAT) mice model. Effect of HDAC inhibitor Valproic acid (VA) alone and in combination with Polyphenolic acetates and also Polyphenolic acetates along with Calreticulin (CAL) induced hyperacetylation causing modulation of apoptosis was also investigated in view of possibility to develop target oriented combination therapy in cancer.Materials and Methods: EAT mice model was established. EAT mice were treated with different PAs, VA and purified, recombinant calreticulin and their combinations by Intra peritoneal route (I.P) which induced transacetylation of histones resulting in apoptosis. After 26 hrs of the above treatment, 2ml of peritoneal fluid was aspirated from mice of all the above groups. The peritoneal fluid was studied for the amount of acetylated histone proteins by Western blotting using commercially available specific Anti- Acetyl Histone (Ac-Lys) Antibodies and extent of apoptosis in peritoneal cells by Flow-Cytometry and fluorescence microscopy.Results: The number of apoptotic cells were represented by the Median (25th, 75th percentile) clearly illustrates significant increase in the no. of apoptotic cells in both PAs viz. 7,8-Diacetoxy-4-Methyl Coumarin (DAMC) and 6-Acetoxy Quinolone (6-AQ) and their combinations with CAL and VA as compared to DMSO control group and the maximum no. of apoptotic cells were observed in Group DAMC+CAL+VA. Increased extent of histone protein acetylation was observed by Western blotting using specific Anti- Acetyl Histone (Ac-Lys) Antibodies.Conclusion: PAs alone and also synergistically with CAL and VA are potential drug candidates for Cancer therapy.Asian Journal of Medical Sciences Vol.7(2) 2015 13-20
Using Mobile Phone Location Data to Develop External Trip Models
Authors: Huntsinger Leta F. , Ward Kyle
Published: November 2015

This paper explores the use of passively collected data on the location of mobile phones in the development of external travel models, which capture trips to, from, and through an area. The data were collected 24 h a day for 1 month during May 2013 for the North Carolina Department of Transportation. The data cover the French Broad River Metropolitan Planning Organization and surrounding counties in North Carolina. This paper details the format of the data collected and the required processing and cleaning to support the development of the external trip models. The process for developing a through-trip table and estimating external trip interchanges in the region is presented, along with validation techniques for both. The results of this effort show that passively collected mobile phone data can be a good source of local information for developing external trip models.
