Published: March 2019

Desde el momento en que surge la ayuda internacional al desarrollo, investigadores y donantes se cuestionan si la misma es realmente eficaz. Actualmente este asunto sigue siendo objeto de investigación y controversia; concretamente en la relación entre ayuda, crecimiento, alivio de la pobreza y otros conceptos de más reciente aparición, como el buen gobierno. En este artículo se profundiza en el origen y los cambios experimentados por la noción de buen gobierno; se analizan los constituyentes y determinantes del mismo, su relación con conceptos cercanos como el de calidad institucional, y sobre todo las ideas y la evidencia creada sobre las relaciones entre el buen gobierno y la efectividad de la ayuda al desarrollo. La propia rúbrica de eficacia de la ayuda es objeto de revisión, debido a la notable diversidad de enfoques sobre los objetivos ante los que en última instancia debe rendir cuentas.
La cuestión de si es el buen gobierno el que atrae y hace más efectiva la ayuda, o si es esta última la que favorece la transición de los países a mejores niveles de gobernanza, sigue planeando en la actualidad sobre el debate de académicos y expertos. En este artículo se presenta el debate en torno a la eficacia de la ayuda. Se da cuenta de que no existe, nuevamente, un consenso general en cuanto a que la ayuda haya sido eficaz para promover el crecimiento económico, y existen tanto defensores como detractores de esta idea.
THE IMPACT OF EXCHANGE RATE VOLATILITY ON EXPORT FLOWS IN DEVELOPING COUNTRIES
Authors: TUMTURK Oğuz 
Published: March 2019

This article investigates the long run impacts of exchange rate
volatilities on export volumes in six developing countries, Turkey, Indonesia,
Brazil, Mexico, Poland, and Chile. The exchange rate volatility is estimated by
both ARCH/GARCH and moving sample standard deviation-based volatility proxies.
Error correction representation of the long run export model reveals that there
is not cointegration relationship for Brazil, Indonesia, and Chile while the
results support the cointegration relationship for Turkey, Mexico, and
Poland. Second, world income is major
determinant driving export volumes in Turkey, Mexico, and Poland. Third, there
is a significant negative relationship between exchange rate level and export
volumes in Turkey and Mexico in line with theory. Finally, the measure of
exchange rate volatility carries a significant negative coefficient in the case
of Poland but a significant positive coefficient in the case of Turkey.

hukuku alanında modern hukuk dünyasında hakim olan bir anlayışın sonucu olup,
Anayasamızın 48. ve 167. maddelerine de uygundur. Ancak ülkemiz uygulamalarında
art niyetli uygulayıcılar yüzünden önce iflas erteleme süresi kısaltılmış, daha

Published: March 2019

O objetivo geral deste trabalho consiste em analisar o processo de envelhecimento populacional nos municípios do Conselho Regional de Desenvolvimento do Litoral e seu potencial impacto sobre as políticas necessárias para o atendimento das demandas desse segmento. A metodologia utilizada foi um levantamento de dados junto ao Instituto Brasileiro de Geografia e Estatística (IBGE) e ao Programa das Nações Unidas para o Desenvolvimento (PNUD). A abordagem de análise foi quantitativa. No que se refere aos resultados, constatou-se inicialmente que no período de 2000-2010 esta foi a região do estado com maior destaque no aumento populacional. Com relação à população acima de 60 anos, este aumento foi de 75% superando as médias estadual e nacional. Por um lado, tem-se o aumento da população idosa nos balneários com pessoas provenientes de regiões metropolitanas do estado, que após a aposentadoria buscam um lugar tranquilo que propicie lazer e maior qualidade de vida. Por outro lado, nos municípios rurais verifica-se os fenômenos do êxodo juvenil, da masculinização e do envelhecimento do campo. Ou seja, embora os balneários apresentem expressivo aumento da população idosa por atrair aposentados, os municípios rurais destacam-se pelo intenso processo de envelhecimento daqueles que permanecem no campo. Em suma, os municípios precisam estar empenhados em atender as deliberações da Política Nacional do Idoso no que se refere à garantia de direitos e à inserção dos idosos no espaço público enquanto sujeitos sociais e coletivos. Os resultados desta pesquisa evidenciam que a população idosa do COREDE Litoral apresenta demandas segundo as especificidades de cada município, o que requer cautela na implementação de políticas públicas, pois estas não podem ser racionalmente planejadas para uma determinada categoria, englobando um universo de indivíduos que na prática não são homogêneos.Palavras-chave: Corede Litoral, Envelhecimento Populacional, Políticas Públicas

Published: March 2019

Objective: to propose a procedure for analyzing the X-ray image of the temporomandibular joint (TMJ) through the automated calculation of linear and angular measurements from craniometry points in comparison with the reference values.Material and methods. Fifty TMJ cone beam computed tomography images were analyzed in 25 volunteers aged 18-25 years with orthognathic bite and physiological occlusion. All the tomography images were analyzed from craniometric points, by using a section corresponding to the midsagittal plane of the TMJ. Angular and linear measurements characterizing the functional capacities of the TMJ were determined. A statistical analysis involved descriptive methods and was carried out by the IBM SPSS 21 statistics.Results. The introduction of automated estimation of TMJ functional capacities from angular and linear measurements made it possible to obtain the following data: the α-angle was 11.99±2.44° for the right TMJ and 12.12±2.78° for the left one; the β-angle was 11.58±2.31° for the right TMJ and 12.42±2.81° for the left one; the γ-angle was 156.41±4.57° for the right TMJ and 155.46±5.50° for the left one. A descriptive statistics checking revealed no gross errors.Conclusion. It is expedient to take into account the findings as reference values to characterize the anatomical and functional state of the TMJ on the x-ray image.
Axial dispersion in aeration tanks
Authors: Murphy Keith L. , Timpany Peter L. 
Published: March 2019

Abstract
The primary function of an aeration tank is to provide sufficient time, and a suitable environment for the assimilation of organics by micro-organisms. Initally assimilation occurs by a rapid absorption or adsorption process. After this initial contact-phenomena between the waste and micro-organisms, the biochemical reactions predominate, but at a decreased rate of organic removal. In any event the extent of treatment may be related to the retention period in the aerator.
Kinetics of Biological Oxidation
Authors: Jank B.E. , Drynan W.R. 
Published: March 2019

Abstract
The future development of the activated sludge process depends to a large extent upon a basic understanding of the kinetics of the biological processes involved and an evaluation of the effects of various factors on these kinetics. A realistic evaluation of the effects of such variables as influent quality and quantity, presence of toxic materials, shock loads, sludge age, pH, etc., on the activated sludge process can be made only if the kinetics of biological oxidation are well defined and reproducible under normal conditions. In addition, a knowledge of the kinetics for a given waste and sludge, particularly in the case of industrial wastes, should provide a more meaningful approach to process design.
Physical Activity as a Moderator of Alzheimer Pathology: A Systematic Review of Observational Studies
Authors: Frederiksen Kristian Steen , Gjerum Le , Waldemar Gunhild , Hasselbalch Steen Gregers 
Published: March 2019

Introduction:
Observational studies have found that physical activity is associated with a
reduced risk of cognitive decline and dementia. Whether physical activity may also reduce the level of
AD pathology, remains undetermined.

Objective:
To examine the relationship between physical activity and AD biomarkers (beta-amyloid1-
42, total tau and phosphorylated tau in CSF, amyloid PET, hippocampal atrophy on MRI and parietotemporal
hypometabolism on brain 18F-FDG-PET).

Methods:
We carried out a systematic review of the observational studies of physical activity and AD
biomarkers in healthy subjects, subjective cognitive complaints, mild cognitive impairment (MCI) and
AD dementia.

Results:
We identified a total of 40 papers, which were eligible for inclusion. Thirty-four studies were
conducted on healthy subjects, 3 on MCI and healthy subjects, 1 on MCI, and 2 on AD and healthy
controls. Six studies reported on CSF biomarkers, 9 on amyloid PET, 29 on MRI and 4 on brain 18FFDG-
PET. The majority of studies did not find a significant association between physical activity and
AD biomarkers

Conclusion:
The quality of included studies with only a few longitudinal studies, limits the conclusions
which may be drawn from the present findings especially regarding the biomarkers other than hippocampal
volume. However, the majority of the identified studies did not find a significant association.

Published: March 2019

Background:
Recent studies have demonstrated the role of micronutrients in the manifestation
of comorbidities associated with obesity. Vitamin D deficiency, in particular, appears to be associated
with increased levels of inflammatory markers, which may lead to chronic low-grade inflammation,
elevating the risk of chronic diseases such as diabetes, metabolic syndrome, and cardiovascular
disease. The objective of this study was to perform a systematic review of observational
studies conducted to investigate the effect of vitamin D deficiency on inflammatory markers in obese
subjects.

Methodology:
This systematic review was conducted in accordance with the “STROBE” and PRISMA
recommendations. Observational studies that evaluated the effect of vitamin D status on inflammatory
markers in obese subjects were selected and reviewed. Searches were conducted in the
PubMed, SciVerse Scopus, and Web of Science databases from February 21 to 22, 2018.

Results:
After the selection and removal of duplicate articles, 10 eligible articles were identified. Results
from eight observational studies showed an association between vitamin D deficiency or insufficiency
in the body and increased concentrations of inflammatory markers in obese individuals. On
the other hand, two of the studies did not demonstrate any correlation. With regard to the inflammatory
markers evaluated, eight studies showed high concentrations of ultra-sensitive C-reactive protein,
five studies found an increase in interleukin-6 concentrations, and two studies noted increased
levels of tumor necrosis factor.

Conclusion:
The data presented in this systematic review provide evidence of the association between
vitamin D deficiency and increased inflammation in obesity.

Authors: ROHMAN ABDUL , CHE MAN YAAKOB BIN , ALI MD. EAKUB 
Published: March 2019

Objective: The objective of this study was to develop Fourier transform infrared (FTIR) spectroscopy in combination with chemometrics of multivariate calibration and discriminant analysis (DA) for the authentication of virgin coconut oil (VCO) from grape seed oil (GSO) and soybean oil (SO).
Methods: FTIR spectra of VCO, GSO, SO and its binary mixture of VCO-SO, and VCO-GSO were scanned at mid-infrared region (4000-650 cm-1) using attenuated total reflectance technique. The wavenumbers were selected based on its capability to provide the best prediction models for quantification and classification of adulterants in VCO assisted by multivariate calibrations and DA, respectively.
Results: The results showed that partial least square (PLS) calibration using absorbance values at combined wavenumbers of 1200-900 and 3027-2985 cm-1 revealed reliable method for quantification of GSO in VCO, as indicated by high value of coefficient of determination (R2) and low value of root mean square of calibration (RMSEC) and root mean square error of prediction (RMSEP). PLS using FTIR spectra at the combined wavenumbers of 1200-1000 and 3025-2995 cm-1 was suitable for quantitative analysis of SO in VCO. DAwas also successfully used for classification of VCO and VCO added with adulterants of GSO and SO.
Conclusion: FTIR spectroscopy in combination with chemometrics of multivariate calibration and DA offered effective tools for the authentication of VCO
