Published: August 2018

The rise of the opioid epidemic and the increasing rate of suicides have drawn attention to mental health and addiction and have highlighted the need for collaboration between public health and behavioral health. However, these 2 fields have had limited engagement with one another. The introduction of Public Health 3.0 and population-based financing models that promote prevention and value in health care have created opportunities and incentives for local health departments and behavioral health agencies and providers to work together. New undertakings include the creation of accountable care organizations, community health needs assessment requirements for all non-profit hospitals, local health department requirements to conduct community Health Assessments (CHA), and increasing numbers of public health departments that are pursing accreditation. We argue that by taking advantage of these opportunities and others, local health departments can play a vital role in addressing critical challenges in mental health and addiction facing their communities.

A novel system for the treatment of wastewater from a tomato processing plant with UV light
Authors: Mahoney Laura , Younis Bassam A. , Simmons Christopher W. 
Published: August 2018

Abstract
In tomato processing plants, the production of paste involves the use of heat to evaporate water to concentrate the tomato juice. The hot water isolated from the juice is then passed through cooling towers to cool it sufficiently before discharge. Recovery of excess and blowdown water from the cooling towers would decrease the net water demand of the plant and improve water efficiency. However, since this water has been exposed to the open air, it must be disinfected before reuse. This research investigated the use of a novel ultraviolet (UV) system to disinfect water from the cooling tower basins located at an industrial tomato processing facility. The objective was to assess, in situ, the disinfection system's performance with regards to its utility, and its ability and to treat wastewater generated in an operational, industrial-scale setting. Beyond typical wastewater microbial assays, 16S rRNA gene sequencing was employed to understand the bacterial communities present in the wastewater, and to screen for microorganisms that may pose a risk for water reuse in food processing facilities.

Abstract
Application of membrane technology for water reclamation has grown significantly in recent years due to reduced footprint size and more consistent product water quality. For a membrane bioreactor (MBR) system, it is critical for it to be robust to allow membrane systems to operate at higher flux without significant increase of trans-membrane pressure (TMP). A full-scale ceramic MBR system was installed at Changi Water Reclamation Plant (CWRP) as part of an MBR retrofit project to increase treatment capacity without expanding the plant's footprint. The nominal capacity of the ceramic MBR system is 15,000 m3/d. The system has been successfully operating since January 2017 with a net flux of 30–60 L/m2-hr (LMH). Stable operation was observed at nominal production capacity for more than 3 months. During that period, the TMP was stable in the range of 9–14 kPa for Tank A and 10–17 kPa for Tank B. Permeate turbidity was recorded in the range of 0.04–0.06 NTU for both Tank A and Tank B.
Sulfate reducing bacteria applied to domestic wastewater

Published: August 2018

Abstract
The application of sulfate reducing bacteria (SRB) to treat municipal wastewater is seldom considered. For instance, due to low sludge yield it can reduce the amount of excess sludge produced significantly. Several studies, mainly at laboratory-scale, revealed that SRB can proliferate in artificial wastewater systems at temperatures of 20°C and lower. So far, the application of SRB in a domestic wastewater treatment plant has been limited. Therefore, this study evaluates the proliferation of SRB at pilot-scale in a moderate climate. This study revealed that SRB were present and active in the pilot fed with domestic wastewater at 13°C, and outcompete methanogens. Stable, smooth and well-settled granule formation occurred, which is beneficial for full-scale application. In the Netherlands the sulfate concentration is usually low (&lt;500 mg/L), therefore the application of SRB seems challenging as sulfate is limiting. Additional measurements indicated the presence of other sulfur sources, therefore higher sulfur levels were available, which makes it possible to remove more than 75% of the chemical oxygen demand (excluding sulfide) based on SRB activity. The beneficial application of SRB to domestic wastewater treatment might therefore be valid for more locations than initially expected.
NOM-removal by the SIX®-process
Authors: Galjaard G. , Koreman E. , Metcalfe D. , Moore G. , Ericsson Per 
Published: August 2018

Abstract
Some waters can have elevated concentrations of dissolved organic carbon (DOC), especially sources like surface waters that are under the influence of secondary effluent, recreation, heavy population, farming and industry. In a number of locations in north-west Europe, for example the United Kingdom and Scandinavia, DOC levels are increasing over time, most likely due to climate change effects and changes in land use. For these types of water, ion exchange (IX) is of interest as a pre-treatment option because the removal of colour and DOC by IX will increase the efficiency of all downstream processes, including: coagulation, membrane filtration, advanced oxidation processes (AOP) and granular activated carbon filtration (GAC). It will also lead to improved water quality (i.e., less by-product formation) and most likely improvements in biostability within the distribution network. Surface waters also contain suspended and colloidal matter, making it nearly impossible to use standard state-of-the-art, fixed bed IX columns. This is because these beds will foul quickly (i.e., head loss build-up) with suspended matter. When this happens, the IX bed starts to function as a filtration bed rather than as an adsorption media. The newly developed suspended ion exchange process SIX® (suspended ion exchange, PWN Technologies, Netherlands) presents an advanced solution for a world-wide challenge: how to remove natural organic matter (NOM/DOC) as a first step in surface water treatment to improve the efficiency of downstream processes and water quality. In addition to the possibility to treat water that contains suspended matter, another advantage is that the process has advanced to an economically and technically feasible process, requiring low contact times and small resin inventories, with a large tolerance for flow fluctuations. Depending on the water source, adding a relatively low concentration of coagulant after IX removes even greater quantities of DOC, especially in the fraction of the high molecular weight organic carbon (whilst the IX primarily removed the humic and fulvic organic fractions). The most important advancement is that almost any commercially available resin can be used, creating the desired flexibility in resin suppliers for water supply companies. This paper describes the process and its advantages and disadvantages compared to conventional technologies. NOM-characterisation with size exclusion chromatography, liquid chromatography – organic carbon detection (SEC/LC-OCD) before and after this process showed the outstanding performance of the process, especially on water types which contain high colour/DOC-concentrations and low total dissolved solids, which are typical of the majority of the surface waters in the north-west of Europe.

Abstract
High concentrations of fluoride in drinking water are reported to be hazardous to human health. This study was conducted to assess the efficiency of mechanochemically-activated aluminosilicate clay soil in removing fluoride from groundwater. The soil was subjected to physicochemical transformation through mechanochemical activation for different time intervals (5, 10, 15 and 30 min). The highest specific surface obtained was about 50 m2/g, with the sample activated for 30 minutes. Fourier Transform Infrared (FT-IR) analyses of samples showed an increase in absorbance by Si-O-H groups at 510 cm−1 with increasing milling time. X-ray diffraction (XRD) analyses revealed that, at 30 minutes milling time, peak broadening was intensified while reflection peak intensities decreased. X-ray fluorescence (XRF) spectrometry showed that silica and alumina were the major clay soil components. Using a dosage of 0.6 g/100 mL of activated clay, a maximum fluoride removal of 41% was achieved using the batch activated for 30 minutes on water spiked with 9 mg-F/L at pH 2.41. The adsorption data fitted both the Langmuir and Freundlich isotherms, but only the pseudo-second-order kinetic, showing chemisorption fluoride removal.
Potential of efficient toilets in Hanoi, Vietnam
Authors: Otaki Yurina , Otaki Masahiro , Aramaki Toshiya 
Published: August 2018

AbstractMany water authorities have promoted the installation of water-saving devices as an effective way of managing residential water demand. However, there has been some controversy about the effectiveness of such devices in studies in developed countries, and few studies have considered the use of water-saving devices in developing countries, where a rapid increase in water demand is expected. This study focused on toilet replacement and the residential water-saving potential in urban Hanoi, Vietnam – a country presently enjoying remarkable economic growth and increasing water demand – using the Monte Carlo simulation, i.e., stochastic, approach. We surveyed the toilets of 134 households. Annual water savings were not large – 2.2 liters per person per day (1.9% of total residential consumption) – despite the assumption that all toilets would be replaced with efficient ones within three years. Based on this study, a rebate to encourage toilet replacement would have limited effect for saving water, contrary to experience in developed countries. Comparing the volume of water saved, the simple analytical model, i.e. the deterministic approach, under-estimated the water-saving potential.
Water quality in earthen dams and potential health impacts: case of Nadosoito Dam, Tanzania

Published: August 2018

Abstract
The aim of the study was to assess seasonal water quality variations in an earthen dam and their potential impact on the health of those using the water for domestic purposes. High values of chemical oxygen demand, from &lt;0.7 to 87 mg/l, and turbidity, from 204 to 53,300 NTU, were reported. Turbidity and total suspended solids were the highest at the onset of rainfall, and generally declined from the wet to the dry season. Ammonia concentrations ranged from 0.14 to 270 mg/l and nitrate from 0.6 to 1,715 mg-N/l, and were highest towards the end of wet season, while NO2-N was highest (290 mg/l) in the dry season. There were some notably high phycocyanin (PC) pigment values (19.9 to 495 μg/l) unique to cyanobacteria, well above the WHO alert level of 30 μg/l. PC is associated with a variety of toxins affecting humans and animals. Possible sources of pollutants include animal droppings/urine and runoff from farms applying fertilisers. A further aim was to assess water treatability with a pilot inclined plate settler system for pollutants and microbial removal. The results of this study suggest that water treatment systems must be designed to take care of the worst influent water quality conditions.
Comparison Between 3D Echocardiography and Cardiac Magnetic Resonance Imaging (CMRI) in the Measurement of Left Ventricular Volumes and Ejection Fraction
Authors: Benameur Narjes , Arous Younes , Ben Abdallah Nejmeddine , Kraiem Tarek 
Published: August 2018

Background:
Echocardiography and Cardiac Magnetic Resonance Imaging (CMRI) are
two noninvasive techniques for the evaluation of cardiac function for patients with coronary artery
diseases. Although echocardiography is the commonly used technique in clinical practice for the
assessment of cardiac function, the measurement of LV volumes and left ventricular ejection fraction (LVEF) by the use of this technique is still influenced by several factors inherent to the protocol acquisition, which may affect the accuracy of echocardiography in the measurement of global
LV parameters.

Objective:
The aim of this study is to compare the end systolic volume (ESV), the end diastolic
volume (EDV), and the LVEF values obtained with three dimensional echocardiography (3D echo)
with those obtained by CMRI (3 Tesla) in order to estimate the accuracy of 3D echo in the assessment of cardiac function.

Methods:
20 subjects, (9 controls, 6 with myocardial infarction, and 5 with myocarditis) with age
varying from 18 to 58, underwent 3D echo and CMRI. LV volumes and LVEF were computed
from CMRI using a stack of cine MRI images in a short axis view. The same parameters were calculated using the 3D echo. A linear regression analysis and Bland Altman diagrams were performed to evaluate the correlation and the degree of agreement between the measurements obtained
by the two methods.

Results:
The obtained results show a strong correlation between the 3D echo and CMR in the
measurement of functional parameters (r = 0.96 for LVEF values, r = 0.99 for ESV and r= 0.98 for
EDV, p < 0.01 for all) with a little lower values of LV volumes and higher values of LVEF by 3D
echo compared to CMRI. According to statistical analysis, there is a slight discrepancy between the
measurements obtained by the two methods.

Conclusion:
3D echo represents an accurate noninvasive tool for the assessment of cardiac function. However, other studies should be conducted on a larger population including some complicated diagnostic cases.

Published: August 2018

Background:
The time and frequency responses of Multiple Quantum Barrier (MQB)
nano-scale Avalanche Photodiodes (APDs) based on Si~3C-SiC material system have been investigated
in this final part.

Methods:
A very narrow rectangular pulse of pulse-width of 0.4 ps has been used as the input optical
pulse having 850 nm wavelength incidents on the p+-side of the MQB APD structures and corresponding
current responses have been calculated by using a simulation method developed by the
authors.

Results:
Finally the frequency responses of the devices are obtained via the Fourier transform of
the corresponding pulse current responses in time domain.

Conclusion:
Simulation results show that MQB nano-APDs possess significantly faster time response
and wider frequency response as compared to the flat Si nano-APDs under similar operating
conditions.

Published: August 2018

This paper emphasises significantly on public relations strategic planning in public participation to gain organisational effectiveness. Grunig (1992) describes organisation's decision affects public and in turn the public affect the organisation's decision. This paper discusses the Situational theory of publics (Grunig, 1992) and highlights communication programmes for public participation in the development of slope area in Bukit Antarabangsa, Selangor. This paper suggests a framework of public relations strategic planning for public participation in MPAJ based on findings obtained from multiple methods of data collection.
