Authors: Alim Nor Shuhada , O. Lintang Hendrik , Yuliati Leny 
Published: October 2019

In this study, a metal-free carbon nitride (CN) was investigated for the first time as a potential fluorescence sensor for detection of nitrate ions (NO3-). The CN was prepared through thermal polymerization of urea precursor at 823 K and characterized by diffuse reflectance ultraviolet-visible (DR UV-Vis), Fourier transform infrared (FTIR), and fluorescence spectroscopies. The DR UV-Vis spectrum confirmed that CN could absorb light up to 450 nm. On the other hand, the FTIR spectrum revealed the presence of graphitic CN single and double bond characters in the 800-1700 cm-1 region. From the fluorescence spectroscopy, three excitation peaks at 278, 310 and 369 nm were observed due to the presence of N=C, C=O and N-C groups, respectively. The fluorescence sensor capability of the CN was then investigated using concentrations of NO3- in the range of 300-1800 mM. It was confirmed that the intensities of the emission sites were quenched linearly with the concentrations of the NO3-. The CN showed good reproducibility with relative standard deviation (RSD) values were 1.5-7.2%. These results suggested that CN can act as the fluorescence sensor for NO3-.

The suitability of product attributes forsuccessful VMI program has been discussed by numerous authors and but not concluded yet. This study is to explain the moderating effects of product attributestoward VMI performance. The data was gathered from 101 of suppliers in manufacturing companies. Data analysis was conducted by employing factor analysis, reliability test, and hierarchical multiple regressions. The findings show that only level of demand visibility is the main predictor of service performance. While, replenishment decision and inventory ownership were predictor to cost performance. The innovative product moderates the relationship between level of demand visibility and VMI performance. The functional product moderates the relationship between replenishment decision and service performance; and the relationship between inventory ownership and cost performance. Suppliers in manufacturing companies should urge their customer to share demand information when engaging in VMI program.However, supplier should give less authority in replenishment decision for functional product to increase the service performance. Supplier also should have low ownership of inventory to ensure better cost saving for functional product.

This paper presents the design process of a synchronous motor of crane system using vector control of line starting [1]. The preliminary design is d-q model armature rotor line start synchronous motor with vector control for decreasing a starting current and torque. The design allows the synchronous motor to operate at both starting and synchronous speed. The basic equations for park transformation of the rotor-stator for proposed vector control to synchronous motor are presented [2]. The starting performance of synchronous motor, for example in crane application, requires rapid dynamics and precise regulation; hence the need of direct control is becoming an urgent demand. This type of control providesanindependent vector control of torqueand current, whichis similar to a separatelyexcited synchronous motor and offersa number ofattractivefeatures.

In the development of Brain Computer Interface (BCI), one important issue is the classification of hand grasping imagination. It is helpful for realtime control of the robotic or a game of the mind. BCI uses EEG signal to get information on the human. This research proposed methods to classify EEG signal against hand grasping imagination using Neural Networks. EEG signal was recorded in ten seconds of four subjects each four times that were asked to imagine three classes of grasping (grasp, loose, and relax). Four subjects used as training data and four subjects as testing data. First, EEG signal was modeled in order 20 Autoregressive (AR) so that got AR coefficients being passed Neural Networks. The order of the AR model chosen based optimization gave a small error that is 1.96%. Then, it has developed a classification system using multilayer architecture and Adaptive Backpropagation as training algorithm. Using AR made training of the system more stable and reduced oscillation. Besides, the use of the AR model as a representation of the EEG signal improved the classification system accuracy of 68% to 82%. To verify the performance improvement of the proposed classification scheme, a comparison of the Adaptive Backpropagation and the conventional Backpropagation in training of the system. It resulted in an increase accuracy of 76% to 82%. The system was validated against all training data that produced an accuracy of 91%. The classification system that has been implemented in the software so that can be used as the brain computer interface.

Phyllanthus gomphocarpus Hook. F is a herb found in tropical rainforest countries and has been widely used in traditional medicine especially in Peninsular Malaysia to treat male infertility problems and increase human health. Ten percent aqueous extraction of PGR was prepared by heating in 40º C for 12 hours and its decoction were freeze dried to obtain crude extract. Total numbers of 24 male rats were randomly divided into 4 groups which NEC, POC, PGR50 and PGR800. Except for NEC group, other groups were induced genitotoxicity by oral supplementation of 200 mg/kg of BPA for 21 consecutive days. For PGR50 and PGR800 groups, the animals were concomitantly supplemented with 50 mg/kg and 800 mg/kg of PGR extracts respectively. Blood and testes sample were collected for hormonal and testes morphometric analysis. Results clearly showed that that testosterone (T), the most important hormone in spermatogenesis process were significantly increased in PGR supplemented groups (p<0.05) compared to NEC and POC groups. For the level of DHT, FSH, and LH hormonal level, the results were varies and can be explained with the deterioration effects of BPA and the hormonal regulations itself. Testes morphometric study showed no significant difference in the seminiferous tubule diameter in each groups but was significantly increased (p<0.05) in the epithelium height, which indicates higher rate of spermatogenesis process. In addition, PGR possessed a protective effect against the toxicity effects of BPA. In conclusion, PGR was suggested to enhance male fertility through improvement of androgenic hormones and possessed a protective effect against genitotoxicity of BPA.

Published: October 2019

In today’s competitive market of manufacturing industry, shorter machining time is one of important factor for reducing the manufacturer’s cost. This paper presents the minimisation of machining time of computer numerical control (CNC) by eliminating the uncut region of sharp corner based on contour parallel milling method. Each uncut region at sharp corner is represented by uncut line which consists of two nodes in x and y directions. An Ant Colony Optimisation (ACO) method is used to optimize the tool path length because of its capability to find the shortest tool path length. The optimisation of tool path length based on ACO algorithm ascertained that the cutting tool remove the uncut line once and able to eliminate the uncut region in the shortest tool path length. To observe the effectiveness of the ACO performance, the simulation results are compared with the results obtained by the previous method. Finally the simulation results show the reduction of 5% machining time compared to previous method.

Key points
Maternal obesity predisposes to metabolic dysfunction in male and female offspring
Maternal high‐fat diet consumption prior to and throughout pregnancy and lactation accelerates offspring metabolic ageing in a sex‐dependent manner
This study provides evidence for programming‐ageing interactions
AbstractHuman epidemiological studies show that maternal obesity (MO) shortens offspring life and health span. Life course cellular mechanisms involved in this developmental programming‐ageing interaction are poorly understood. In a well‐established rat MO model, female Wistar rats ate chow (controls (C)) or high energy, obesogenic diet to induce MO from weaning through pregnancy and lactation. Females were bred at postnatal day (PND) 120. Offspring (F1) of mothers on control diet (CF1) and MO diet (MOF1) delivered spontaneously at terms. Both CF1 and MOF1 ate C diet from weaning throughout the study. Offspring were killed at PND 36, 110, 450 and 650. We determined body and liver weights, liver and serum metabolite concentrations, hormones and oxidative stress biomarkers. Male and female CF1 body weight, total fat, adiposity index, serum leptin, insulin, insulin resistance, and liver weight, fat, triglycerides, malondialdehyde, reactive oxygen species and nitrotyrosine all rose with differing ageing trajectories. Female CF1 triglycerides were unchanged with age. Age‐related increases were greater in MOF1 than CF1 in both sexes for all variables except glucose in males and females and cholesterol in males. Cholesterol fell in CF1 females but not MOF1. Serum corticosterone levels were higher in male and female MOF1 than CF1 and declined with age. DHEA serum levels were lower in male and female MOF1 than CF1. Liver antioxidant enzymes decreased with age (CF1 and MOF1). Conclusions: exposure to the developmental challenge of MO accelerates progeny ageing metabolic and endocrine profiles in a sex specific manner, providing evidence for programming‐ageing interactions.

ABSTRACT
We used geologic mapping, tephrochronology, and 40Ar/39Ar dating to describe evidence of a ca. 3.5 Ma pluvial lake in Eureka Valley, eastern California, that we informally name herein Lake Andrei. We identified six different tuffs in the Eureka Valley drainage basin, including two previously undescribed tuffs: the 3.509 ± 0.009 Ma tuff of Hanging Rock Canyon and the 3.506 ± 0.010 Ma tuff of Last Chance (informal names). We focused on four Pliocene stratigraphic sequences. Three sequences are composed of fluvial sandstone and conglomerate, with basalt flows in two of these sequences. The fourth sequence, located ~1.5 km south of the Death Valley/Big Pine Road along the western piedmont of the Last Chance Range, included green, fine-grained, gypsiferous lacustrine deposits interbedded with the 3.506 Ma tuff of Last Chance that we interpret as evidence of a pluvial lake. Pluvial Lake Andrei is similar in age to pluvial lakes in Searles Valley, Amargosa Valley, Fish Lake Valley, and Death Valley of the western Great Basin. We interpret these simultaneous lakes in the region as indirect evidence of a significant glacial climate in western North America during marine isotope stages Mammoth/Gilbert 5 to Mammoth 2 (MIS MG5/M2) and a persistent Pacific jet stream south of 37°N.

ObjectivesDisparities in the global burden of breast cancer have been identified. We aimed to investigate recent patterns and trends in the breast cancer incidence and associated mortality. We also assessed breast cancer-related health inequalities according to socioeconomic development factors.DesignAn observational study based on the Global Burden of Diseases.MethodsEstimates of breast cancer incidence and mortality during 1990–2016 were obtained from the Global Health Data Exchange database. Subsequently, data obtained in 2016 were described using the age-standardised and age-specific incidence, mortality and mortality-to-incidence (MI) ratios according to sociodemographic index (SDI) levels. Trends were assessed by measuring the annual percent change using the joinpoint regression. The Gini coefficients and concentration indices were used to identify between-country inequalities.ResultsCountries with higher SDI levels had worse disease incidence burdens in 2016, whereas inequalities in the breast cancer incidence had decreased since 1990. Opposite trends were observed in the mortality rates of high and low SDI countries. Moreover, the decreasing concentration indices, some of which became negative, among women aged 15–49 and 50–69 years suggested an increase in the mortality burdens in undeveloped regions. Conversely, inequality related to the MI ratio increased. In 2016, the MI ratios exhibited distinct gradients from high to low SDI regions across all age groups.ConclusionsThe patterns and trends in breast cancer incidence and mortality closely correlated with the SDI levels. Our findings highlighted the primary prevention of breast cancer in high SDI countries with a high disease incidence and the development of cost-effective diagnostic and treatment interventions for low SDI countries with poor MI ratios as the two pressing needs in the next decades.

Published: October 2019

IntroductionProstate cancer is one of the most frequent cancers among men. However, screening for prostate cancer carries many risks and a small benefit. Thus, based on the available evidence, most medical organisations advocate a shared decision-making process, in which decision aids may play an important role. Nevertheless, to date there is no such instrument to be used by Portuguese men. Our goal is to translate and perform the cultural adaptation of an English language prostate cancer screening decision aid called ‘Making the best choice’, in web and printed formats, which has been developed and tested by a workgroup from Georgetown University (USA).Methods and analysisCulturally and technically inappropriate recommendations in the original decision aid will be reviewed by the process coordinator and a linguistic expert. Two forward translations from English to Portuguese will be done, followed by a back-translation and an independent expert review. We will further improve the decision aid through an iterative process of data collection, data analysis and decision aid review. Individual semistructured cognitive interviews will be conducted and audiotaped with 55–69-year-old men recruited from the local community (urban and suburban) of Oporto district. We plan a total sample size of 30 participants (15 interviews per format). All participants will receive written information about the study and will sign individual consent forms. After verbatim transcription of the audiofiles, a thematic categorical analysis will be conducted using Ligre Software.Ethics and disseminationThe study protocol was approved by the Health Ethics Committee from Centro Hospitalar de São João/Faculdade de Medicina da Universidade do Porto. Results from this study will be disseminated in peer-reviewed publications and the Portuguese decision aid will available to Portuguese men.

ObjectiveTo explore healthcare providers’ perspective on non-communicable disease (NCD) prevention and management services provided through the NCD corners in Bangladesh and to examine challenges and opportunities for strengthening NCD services delivery at the primary healthcare level.DesignWe used a grounded theory approach involving in-depth qualitative interviews with healthcare providers. We also used a health facility observation checklist to assess the NCD corners’ service readiness. Furthermore, a stakeholder meeting with participants from the government, non-government organisations (NGOs), private sector, universities and news media was conducted.SettingTwelve subdistrict health facilities, locally known as upazila health complex (UHC), across four administrative divisions.ParticipantsParticipants for the in-depth qualitative interviews were health service providers, namely upazila health and family planning officers (n=4), resident medical officers (n=6), medical doctors (n=4) and civil surgeons (n=1). Participants for the stakeholder meeting were health policy makers, health programme managers, researchers, academicians, NGO workers, private health practitioners and news media reporters.ResultsParticipants reported that diabetes, hypertension and chronic obstructive pulmonary disease were the major NCD-related problems. All participants acknowledged the governments’ initiative to establish the NCD corners to support NCD service delivery. Participants thought the NCD corners have contributed substantially to increase NCD awareness, deliver NCD care and provide referral services. However, participants identified challenges including lack of specific guidelines and standard operating procedures; lack of trained human resources; inadequate laboratory facilities, logistics and medications; and poor recording and reporting systems.ConclusionThe initiative taken by the Government of Bangladesh to set up the NCD corners at the primary healthcare level is appreciative. However, the NCD corners are still at nascent stage to provide prevention and management services for common NCDs. These findings need to be taken into consideration while expanding the NCD corners in other UHCs throughout the country.

Published: October 2019

ObjectivesTo investigate whether the rate of spend on child and adolescent mental health is influenced by demand for other competing services in local commissioning decisions.DesignAnalysis of spend data by Clinical Commissioning Groups (CCG), including other publicly available data to control for variation in need.SettingLocal commissioning decisions in the National Health Service.ParticipantsCommissioning of health services across 209 CCGs.Main outcome measuresAssociation between the rate of child and adolescent mental health spend and demand for child and adolescent mental health services (CAMHS), adult mental health services and physical health services after adjusting for confounding factors.ResultsAn additional percentage point in the proportion of children in care is associated with 4% higher child and young person mental health (CYP MH) spend per person aged 0–18 (ratio of means: 1.04; 95% CI 1.00 to 1.07). Spending £100 more on physical health services was associated with 9% lower spend in CYP MH per person aged 0–18 (ratio of means: 0.91; 95% CI 0.84 to 0.99).ConclusionsHealthcare commissioners in England face a challenge in balancing competing needs. This paper contributes to our understanding of this by quantifying the possible extent of the trade-off between physical health and CYP MH when allocating budgets. Any attempt to explain the variation in CAMHS spend must also take account of demand for other services.
