Authors: Wei Wycliffe Enli , Fook-Chong Stephanie , Chen Wen Kai , Chlebicki Maciej Piotr , Gan Wee Hoe 
Published: August 2019

Abstract
Background

To protect hospitalized patients who are more susceptible to complications of influenza, seasonal influenza vaccination of healthcare workers (HCW) has been recommended internationally. However, its effectiveness is still being debated. To assess the effectiveness of HCW influenza vaccination, we performed an ecological study to evaluate the association between healthcare worker influenza vaccination and the incidence of nosocomial influenza in a tertiary hospital within Singapore between 2013-2018.Methods

Nosocomial influenza was defined by influenza among inpatients diagnosed 7 days or more post-admission by laboratory testing, while healthcare worker influenza vaccination rate was defined as the proportion of healthcare workers that was vaccinated at the end of each annual seasonal vaccination exercise. A modified Poisson regression was performed to assess the association between the HCW vaccination rates and monthly nosocomial influenza incidence rates.Results

Nosocomial influenza incidence rates followed the trend of non-nosocomial influenza, showing a predominant mid-year peak. Across 2,480,010 patient-days, there were 256 nosocomial influenza cases (1.03 per 10,000 patient-days). Controlling for background influenza activity and the number of influenza tests performed, 10% increase in vaccination coverage corresponded to 11% decrease in nosocomial influenza incidence rate (IRR 0.89, 95%CI:0.69-1.15, p =0.37).Conclusion

We observed a negative association between influenza vaccination rates and nosocomial influenza incidence rates, although statistical significance was not reached. Aligning local HCW vaccine timing and formulation to that of the Southern Hemisphere may improve effectiveness. HCW vaccination remains important but demonstrating its effectiveness in preventing nosocomial influenza is challenging.
Linearization of the sensors characteristics: a review
Authors: Islam Tarikul , Mukhopadhyay S. C. 
Published: August 2019

Abstract
Today, the sensing devices play an important role for various system automation and monitoring of different physical and chemical parameters. Nonlinearity is an important long-time issue for most of the sensors, so to compensate nonlinearity, various linearization schemes are reported in the literature. The accuracy of linearization schemes depends on the type and the nonlinearity value of the sensor output. Since it is difficult to find an exact polynomial equation or other functions to represent the response curve; it gives more error when the measurement parameter is determined from the inverse approximation functions. As many sensors are used for different applications, the linearized characteristics will simplify the design, calibration, and accuracy of the measurement. This paper presents a review of different methods applied to linearize sensor characteristics reported in the literature. Due to availability of high-performance analog devices, analog methods are still popular among many researchers. However, due to the advancement of IC technologies, hardware implementation of the software methods can be done easily with reduced time, cost, and more accuracy, so the digital methods combined with software techniques perform the job with better flexibility and efficiency.
Integrated numerical model for irrigated area water resources management

Published: August 2019

Abstract
The likelihood of future global water shortages is increasing and further development of existing operational hydrologic models is needed to maintain sustainable development of the ecological environment and human health. In order to quantitatively describe the water balance factors and transformation relations, the objective of this article is to develop a distributed hydrologic model that is capable of simulating the surface water (SW) and groundwater (GW) in irrigation areas. The model can be used as a tool for evaluating the long-term effects of water resource management. By coupling the Soil and Water Assessment Tool (SWAT) and MODFLOW models, a comprehensive hydrological model integrating SW and GW is constructed. The hydrologic response units for the SWAT model are exchanged with cells in the MODFLOW model. Taking the Heihe River Basin as the study area, 10 years of historical data are used to conduct an extensive sensitivity analysis on model parameters. The developed model is run for a 40-year prediction period. The application of the developed coupling model shows that since the construction of the Heihe reservoir, the average GW level in the study area has declined by 6.05 m. The model can accurately simulate and predict the dynamic changes in SW and GW in the downstream irrigation area of Heihe River Basin and provide a scientific basis for water management in an irrigation district.
A hybrid optimization approach for parameter estimation of confined and leaky confined aquifers
Authors: Ayvaz M. Tamer , Gurarslan Gurhan 
Published: August 2019

Abstract
The main objective of this study is to propose a linked simulation–optimization approach for solving aquifer parameter estimation problems from pumping test results. In the simulation part of the proposed approach, the drawdowns at given monitoring points and times are calculated by considering the Theis and Hantush approaches for confined and leaky confined aquifers, respectively. This simulation part is then integrated to a newly proposed hybrid optimization approach, namely DE–Solver, which integrates the differential evolution (DE) algorithm and generalized reduced gradient (GRG) method of the spreadsheet Solver add-in. The performance of the proposed approach is evaluated by considering two pumping test data for confined and leaky confined aquifers. Identified results indicate that the proposed approach provides better results than those obtained by using different approaches in the literature.
Constraints, performance and perspectives of anaerobic sewage treatment: lessons from full-scale sewage treatment plants in Brazil
Authors: Bressani-Ribeiro T. , Chamhum-Silva L. A. , Chernicharo C. A. L. 
Published: August 2019

AbstractThere are hundreds of full-scale upflow anaerobic sludge blanket (UASB) reactors in operation in various parts of the tropical world, notably in India and Latin America, Brazil being the holder of the largest park of anaerobic reactors for sewage treatment in the world. Despite the recognized advantages of UASB reactors, there are problems that have prevented their maximum operational performance. Neglecting the existence and delaying the solution of these challenges can jeopardize the important advances made to date, impacting the future of anaerobic technology in Brazil and in other countries. This work aims to evaluate the operational performance of five full-scale UASB reactors in Brazil, taking into account a monitoring period ranging between two and six years. The main observed design, construction, and operational constraints are discussed. Some outlooks for important upcoming developments are also provided, considering that most of the observed drawbacks can be tackled without significant increases on reactor costs.

Published: August 2019

Background::Vitamin C (VC) is believed to enhance immunity and is regularly integrated as a supplementary agent during several treatments.Objective::The green (GC) and roasted (RC) coffee (Coffea arabica) aqueous extracts (0, 125, 250 and 500 μg/ml) combined with VC (50 μg/ml) were examined on the cancerous MCF-7 cell line and normal human lymphocytes.Methods::Neutral red uptake assay, comet assay, immunocytochemical reactivity for protein expression and mRNA expression of apoptosis-related genes were performed.Results::A significant (P< 0.05) concentration-dependent increase of apoptotic features, such as morphological changes, and abundant nuclear condensation, altered the expression of p53 and caspase-3 mRNA, down-regulation of Bcl-2 protein as well as the acidic autophagosomal vacuolization in treated cells. The oxidative stress and DNA single-strand breaks were noticed too.Conclusion::These results suggest that coffee in combination with VC undergoes apoptotic anticancer pathway. This supports the integration of coffee and VC as a valuable candidate for anticancer research and treatments.

Published: August 2019

Background:
Numerous causes of infection in arthroplasties are related to biofilm formation
on implant surfaces. In order to circumvent this problem, new alternatives to prevent bacterial
adhesion biosurfactants-based are emerging due to low toxicity, biodegradability and antimicrobial
activity of several biosurfactants. We revised all patents relating to biosurfactants of applicability
in orthopedic implants.

Methods:
This work aims to evaluate the capability of a lipopeptide produced by Bacillus subtilis
ATCC 19659 isolates acting as inhibitors of the adhesion of Escherichia coli ATCC 25922 and
Staphylococcus aureus ATCC 29213 onto titanium and stainless steel surfaces and its antimicrobial
activity.

Results:
The adhesion of the strains to the stainless-steel surface was higher than that of titanium.
Preconditioning of titanium and stainless-steel surfaces with 10 mg mL-1 lipopeptide reduced the
adhesion of E. coli by up to 93% and the adhesion of S. aureus by up to 99.9%, suggesting the
strong potential of lipopeptides in the control of orthopedic infections. The minimal inhibitory
concentration and minimum bactericidal concentration were 10 and 240 µg mL-1 for E. coli and
S. aureus, respectively.

Conclusion:
The lipopeptide produced by Bacillus subtilis ATCC 19659 presented high biotechnological
application in human health against orthopedic implants infections.
Cost-effective Heuristic Workflow Scheduling Algorithm in Cloud Under Deadline Constraint
Authors: Meena Jasraj , Vardhan Manu 
Published: August 2019

Background:
Cloud computing is used to deliver IT resources over the internet. Due to
the popularity of cloud computing, nowadays, most of the scientific workflows are shifted towards
this environment. Many algorithms have been proposed in the literature to schedule scientific workflows
in the cloud, but their execution cost is very high as they are not meeting the user-defined
deadline constraint.

Aim:
This paper focuses on satisfying the user-defined deadline of a scientific workflow while minimizing
the total execution cost.

Methods:
So, to achieve this, we proposed a Cost-Effective under Deadline (CEuD) constraint
workflow scheduling algorithm.

Results:
The proposed CEuD algorithm considers all the essential features of the Cloud and resolves
the major issues such as performance variation and acquisition delay.

Conclusion:
We compared the proposed CEuD algorithm with the existing literature algorithms for
scientific workflows (i.e., Montage, Epigenomics, and CyberShake) and obtained better results for
minimizing the overall execution cost of the workflow while satisfying the user-defined deadline.
Social Media Use and HIV Screening Uptake Among Deaf Adults in the United States: Cross-Sectional Survey Study
Authors: Argenyi Michael , Kushalnagar Poorna 
Published: August 2019

Background
About 46% of US adults obtain recommended HIV screening at least once during their lifetime. There is little knowledge of screening rates among deaf and hard-of-hearing adults who primarily use American Sign Language (ASL), or of social media as a potentially efficacious route for HIV prevention outreach, despite lower HIV/AIDS-specific health literacy and potentially higher HIV seropositivity rates than hearing peers.

Objective
We investigated both the likelihood of HIV screening uptake among deaf adults in the past year and over one year ago, and the relationship between social media use and HIV screening uptake among deaf adult ASL users.

Methods
The Health Information National Trends Survey in ASL was administered to 1340 deaf US adults between 2015-2018. Modified Poisson with robust standard errors was used to assess the relationship between social media usage as a predictor and HIV screening as an outcome (screened more than one year ago, screened within the past year, and never been screened), after adjusting for sociodemographics and sexually transmitted disease (STD) covariates.

Results
The estimated lifetime prevalence of HIV screening uptake among our sample was 54% (719/1340), with 32% (429/1340) in the past year. Being of younger age, male gender, black, lesbian, gay, bisexual, or queer, or having some college education or a prior STD were associated with HIV screening uptake. Adjusting for correlates, social media use was significantly associated with HIV screening in the past year, compared to either lifetime or never.

Conclusions
Screening falls well short of universal screening targets, with gaps among heterosexual, female, Caucasian, or older deaf adults. HIV screening outreach may not be effective because of technological or linguistic inaccessibility, rendering ASL users an underrecognized minority group. However, social media is still a powerful tool, particularly among younger deaf adults at risk for HIV.

La Organización Mundial del Comercio (OMC) y la reducción del espacio para la política: El caso argentino ante el resurgimiento de la restricción externa durante la posconvertibilidad
Authors: Padín Juan Manuel 
Published: August 2019

La creación de la OMC a mediados de los años ´90 limitó el espacio para la política comercial. Un ejemplo concreto de esta situación lo ofrecen los reducidos márgenes de acción disponibles con los que contó la Argentina para administrar el flujo de divisas por la vía comercial ante la reaparición de la restricción externa a partir del año 2011. En tal sentido, el presente trabajo se propone examinar los alcances de las reglas de la OMC evaluando las alternativas que ofrece esta Organización para enfrentar una situación crítica en la balanza de pagos a partir del análisis del caso argentino.

Published: August 2019

Background:The aim of this study is to highlight the importance of cryptococcosis as one of the most common fungal infections of the central nervous system, stressing the consideration of a cryptococcoma within the list of differential diagnosis of intraventricular masses in immunocompetent hosts.Case Description:We present the case of an immunocompetent 41-year-old female from Philippines with an intraventricular cryptococcoma due toCryptococcus neoformans, mimicking an intraventricular primary brain tumor, who had hydrocephalus. She was approached as having a neoplastic lesion and underwent surgical resection plus third ventriculostomy through endoscopy. Later in her evolution, we realized the infectious nature of the lesion, and antifungal systemic therapy was initiated. In the end, she needed the placement of a ventriculoperitoneal shunt to maintain a good neurologic status. Despite all our efforts, she had a fatal outcome due to various complications.Conclusion:Our case is the first intraventricular cryptococcoma due toC. neoformans, as far as we know, to be reported in English, German, or Spanish literature. Our report stresses the importance to consider this kind of infection in immunocompetent patients, to raise the level of suspicion of this diagnosis, and to know the complications and management options.
