Published: June 2019

The fungus Fusarium graminearum is the causative agent of economically significant plant diseases such as Fusarium Healed Blight (FHB) of cereals, its mycotoxins as deoxynivalenol (DON), Nivalenol (NIV) and Zearalenone (ZEN) contaminate wheat and other grains. The objectives of the present study were to determine the mechanism by which the bacterium Pseudomonas aeruginosa inhibits the growth of F. graminearum. Our results indicate that P. aeruginosa metabolites as pyocyanin has effective antifungal properties. Pyocyanin was produced by P. aeruginosa when cultured on mineral salt medium and reached a maximum concentration after 72 h. Pyocyanin significantly decreased mycotoxins of F. graminearum, a 25 mg/ml of pyocyanin for 72 h decreased DON by 68.7% and NIV by 57.7%.

Real-Time PCR analysis demonstrated that the antifungal effect is mediated by downregulation of the Pleiotropic Drug Resistance (PDR) subfamily FgABC3. 25 mg/ml of pyocyanin decreased FgABC3-mRNA by 60%, inhibited the fungal growth and decreased the area of mycelial growth at 12, 24, 36 and 72 h post incubation by 40–50%. Deletion of FgABC3 led to enhanced accumulation of DON and NIV by 40 and 60%, respectively.

The data presented in this report may have significance in understanding mechanism by which certain bacterial metabolites exert a beneficial effect and for developing antifungal drugs.

Diabetes management should focus on biopsychosocial aspects and comprehensive care. The philosophical tenets of Buddhism can be a source of inspiration for both the individual with diabetes and health care provider. Buddhism preaches the immutable relationship between action and outcomes. This has a corollary in diabetes care; optimized metabolic control in diabetes is associated with improved short- and long-term outcomes and a legacy effect. Buddhism emphasizes on maintaining a “middle path.” When applied to diabetes care, this would mean avoiding both extremes of hyperglycemia and hypoglycemia and optimization of metabolic health while minimizing treatment-emergent adverse events. Mindfulness meditation-based stress reduction strategies may further improve not only psychological health but also biophysical outcomes in diabetes and merit further research.
Microlitiasis testicular como factor de riesgo de Cáncer testicular - Estudio de casos y controles
Authors: López-Ramos Hugo , Medina-Rico Mauricio , Manjarrés Sofía , Usubillaga Maria Camila , Sierra Daniela
Published: June 2019

Introducción Con una prevalencia entre el 1,5% y el 5,6%, la microlitiasis testicular es un hallazgo incidental. Aunque se ha propuesto una posible asociación entre la microlitiasis testicular y el cáncer testicular dicha relación no ha sido comprobada.

Objetivos Establecer la relación entre microlitiasis testicular y cáncer testicular.

Métodos Se realizó un estudio de casos y controles con la base de datos de un hospital de la ciudad de Bogotá de pacientes atendidos entre 2007 y 2017. Tanto casos como controles debían tener entre 5 y 35 años de edad, sin otros antecedentes que aumentaran el riesgo de cáncer testicular (criptorquidia, antecedente de cáncer testicular contralateral). Los casos debían tener reporte ecográfico y patológico del cáncer testicular así como una historia clínica completa de valoración por Urología. Los controles fueron pacientes que consultaron por otros cuadros de molestia testicular a quienes se les descartó ecográficamente la presencia de cáncer.

Resultados Se identificaron 24 casos y 96 controles. Al momento de calcular los riesgos relativos indirectos, se obtuvieron un OR crudo de 7,86 (95% CI 2,3 - 26,86) y un OR ajustado por tabaquismo de 10,66 (95% IC 3,29 - 34,55). Al ajustar por edad, historia de cáncer familiar y antecedente de varicocele, no se encontraron diferencias.

Conclusión Existe una aparente asociación entre microlitiasis testicular y cáncer testicular. A pesar de eso, estudios con tamaños de muestra más grande serían beneficiosos. Así mismo, al no poder determinar la existencia de una asociación temporal que permita hablar de causalidad entre las dos condiciones, esos resultados deben tomarse con cautela.

Published: June 2019

Introduction Metabolic syndrome (MetS) is a combination of abdominal obesity, atherogenic dyslipidemia, elevated blood pressure, and elevated plasma glucose. MetS patients have higher chances of developing insulin resistance, visceral adiposity, atherogenic dyslipidemia, and thus coronary artery disease and stroke. Alteration of platelet indices in diabetes mellitus, atherosclerosis, and other proinflammatory states has been described in multiple studies. Thus, this study was carried out to assess platelet indices in MetS.

Objectives This study was carried out to assess platelet indices in MetS.

Methods A cross-sectional study was carried out at Acharya Vinoba Bhave Rural Hospital, a tertiary care center over a period of 2 months from June 1, 2018 to July 31, 2018. Fifty patients diagnosed as having MetS, and 50 healthy controls were chosen. Estimation of anthropometric parameters including waist circumference; measurement of blood pressure; biochemical parameters including lipid profile; and platelet indices including plateletcrit, mean platelet volume (MPV), and platelet distribution width (PDW) were carried out.

Statistical Analysis Statistical analyses were carried out using inferential statistics, including chi-square test and Student's unpaired t-test, and software SPSS version 22.0 (IBM Corporation, Armonk, New York, United States) with GraphPad Prism version 6.0 (Informer Technologies, Inc. Los Angeles, California, United States) was used, with p < 0.05 being considered as significant.

Results A statistically significant, positive correlation was found between the waist circumference, systolic blood pressure, serum triglyceride levels, and plateletcrit, with the MetS status of patients (p < 0.05).

Conclusion This study revealed that MetS is a proinflammatory and prothrombotic state, characterized by alteration of platelet indices. Plateletcrit was shown to be a statistically significant biomarker along with other parameters such as waist circumference, systolic blood pressure, and serum triglyceride levels. Early detection and follow-up of patients using these markers can lead to an overall decline in morbidity and mortality owing to MetS.

Published: June 2019

Introduction Pulmonary embolism (PE) is a relatively common cardiovascular emergency. It can lead to a variety of outcomes, from potentially reversible right ventricular failure (by occluding the pulmonary arterial bed) to eventual death. The diagnosis of PE is often missed due to its nonspecific clinical presentation.

Materials and Methods This is a descriptive cross-sectional study conducted at tertiary care center in India from October 1, 2016 to September 30, 2018, which includes 36 cases of PE. Institutional ethics committee clearance was obtained before start of the study. Written and informed consent was obtained from all patients. Patients were informed regarding purpose, procedures, risks, and benefits of the study in their own vernacular language.

Results The age-wise distribution of patients in this study showed that most patients were up to 40 years amounting to 58.4% of cases. Sex-wise distribution also showed that most patients were male (66.7%). Fifty percent of the patients had no thrombosis on Color Doppler findings of the involved limb, and 31.25% had superficial venous thrombosis. Blood investigation revealed that 94.4% patients had troponin negative and 94.4% had D-dimer positive. This study also attempted to correlate the D-dimer findings and Well's score. It can be seen that as per Well's score, 13 patients were with high probability, 18 with moderate probability, and 5 with low probability.

Conclusion This study states that D-dimer assays are highly sensitive and have a low rate of false-negative results. The assays have been found safe and effective when the clinical probability of PE is low. When the D-dimer result is negative in patients with low clinical probability of having PE, the presence of acute PE can be safely ruled out without diagnostic imaging.

Published: June 2019

We report studies on the photocatalytic formation of C–S bonds to form benzothiazoles via an intramolecular cyclization and sulfenylated indoles via an intermolecular reaction. Cyclic voltammetry (CV) and density functional theory studies suggest that benzothiazole formation proceeds via a mechanism that involves an electrophilic sulfur radical, while the indole sulfenylation likely proceeds via a nucleophilic sulfur radical adding into a radical cationic indole. These conditions were successfully extended to several thiobenzamides and indole substrates.
Is Endothelial Neoplastic Implantation the Reason for the Intravenous Leiomyomatosis in the Heart without Direct Growth from Vena Cava? A Report of Six Cases
Authors: Li Yunzhu , Miao Qi , Cheng Ninghai , Liu He , Ma Guotao
Published: June 2019

Intravenous leiomyomatosis (IVL) with intracardiac involvement is a rare condition. Previous case reports have described direct tumor extension into the vena cava and cardiac chamber. Six patients with intracardiac lesion without direct growth from the IVC were admitted. Surgical resections were performed including total hysterectomy and bilateral salpingo-oophorectomy. Post-operative pathology revealed intravenous leiomyomatosis. The endothelial neoplastic implantation of IVL is a possible reason for the disseminated lesions of IVL within venous system. Awareness of this entity helps clinicians avoid misdiagnosis and take appropriate treatment.
The Health Educator Changing Times, Changing Needs: The Evolution from Instructor to Facilitator
Authors: Jalang'o Atieno G.
Published: June 2019

The health scene is undergoing numerous transitions worldwide. Among the forefront health issues are the escalating incidence of noncommunicable and chronic diseases. The nature of these conditions imposes a significant burden on health resources. However, the greater and often silent brunt is borne by the people afflicted by them. They are charged with making lifelong, daily decisions that significantly bear an impact on their care. The health educator workforce is dwindling, but the need for health literacy is on the rise. It is therefore critical that health educators need to be trained in a way that ensures their performance in imparting health-related knowledge and skills is maximized to ensure optimal outcomes in persons living with chronic disease. Patient empowerment is key, and embracing the patients as partners in the education process rather than recipients is advocated by numerous authors. It is also important to ensure we embrace evidence that have proven useful in other areas such as HIV/AIDS management. Last, it is useful to embrace the changing role of the health education, not merely as instructor charged to deliver health information but rather as a facilitator of behavior change.

PMOXA/PAA brushes toward on-line preconcentration for BSA in capillary electrophoresis
Authors: Liu Xiao-ru , Pan Chao , Wang Yan-mei
Published: June 2019

In this work, a binary-mixed-brushes-coated (BBC) capillary with switchable protein adsorption/desorption properties was developed and applied for on-line preconcentration of proteins. Firstly, amine-terminated poly(2-methyl-2-oxazoline) (PMOXA-NH2) and thiolterminated poly(acrylic acid) (PAA-SH) were synthesized by using cationic ring-opening polymerization (CROP) and reversible addition fragmentation chain transfer (RAFT) polymerization, respectively. Then, the BBC capillary based on poly(2-methyl-2-oxazoline) (PMOXA) and poly(acrylic acid) (PAA) was prepared by sequentially grafting of PMOXA-NH2 and PAA-SH onto fused-silica capillary inner surface through poly(dopamine) (PDA) as an anchor. The obtained PMOXA/PAA coating formed on the capillary or capillary’s raw material was characterized in terms of the thickness, surface chemical composition by using scanning electron microscope (SEM) and X-ray photoelectron spectrum (XPS). The switchable protein adsorption/desorption performance of the BBC capillary was investigated by using fluorescence microscope under different solutions with certain pH and ionic strength (I). The results showed that bovine serum albumin (BSA) could be adsorbed on BBC capillary at pH=5.0 (I=10−5 mol/L), and then the adsorbed BSA could be released at pH=9.0 (I=0.1 mol/L). This switchable protein adsorption/desorption property of coated capillary was then used to preconcentrate proteins on-line for increasing the detection sensitivity of BSA in capillary electrophoresis (CE). With this method, a sensitivity enhancement factor (SEF) more than 5000 for BSA detection was obtained.
Role of reduced defects for coupling reactions of acetaldehyde on anatase TiO2(001)-(1 × 4) surface
Authors: Ji Yuan-yuan , Zheng Yi , Ma Xiao-chuan , Cui Xue-feng , Wang Bing
Published: June 2019

The chemistry of acetaldehyde (CH3CHO) adsorbed on the anatase TiO2(001)-(1×4) surface has been investigated by temperature-programmed desorption (TPD) method. Our experimental results provide the direct evidence that the perfect lattice sites on the anatase TiO2(001)-(1×4) surface are quite inert for the reaction of CH3CHO, but the reduced defect sites on the surface are active for the thermally driven reductive carbon-carbon coupling reactions of CH3CHO to produce 2-butanone and butene. We propose that the coupling reactions of CH3CHO on the anatase TiO2(001)-(1×4) surface should undergo through the adsorption of paired CH3CHO molecules at the reduced defect sites, since the existing reduced Ti pairs provide the suitable adsorption sites.

Authors: Fang Li-zhi , Zhou Xiong , Xia Hai-ping , Hu Jian-xu , Zhang Jian-li , Chen Bao-jiu
Published: June 2019

High quality LiLuF4 single crystals doped with various Pr3+ ions were synthesized by a vertical Bridgman method in completely sealed platinum crucibles. The excitation spectra spans from 420 nm to 500 nm. The prepared single crystals exhibit a blue band at 480 nm (3P0 → 3H4), a green band at 522 nm (3P1 → 3H5), and a red band at 605 nm (1D2 → 3H4) when excited at 446 nm; their corresponding average lifetimes are 38.5 µs, 37.3 µs, and 36.8 µs, respectively, which are much longer than those in oxide single crystals. The effects of excitation wavelength and doping concentration on emission intensities and chromaticity coordinates are investigated. The optimal Pr3+ concentration is confirmed to be 0.5%. The temperature dependent emission shows that the emission intensity constantly decreases with the increase of temperature from 298 K to 443 K due to the enhancement of non-radiative quenching at high temperature. The 3P0 → 3H4 transition is the most vulnerable to temperature, followed by the 3P1 → 3H5 transition and 1D2 → 3H4 transition.

Authors: Chen Xue-fei , Fan Wei , Zhou Xiao-guo , Liu Shi-lin
Published: June 2019

Raman spectra of 1,2,4-triazole-3-carboxylate (TC− anion) and its ring-deprotonated derivative (dpTC2− dianion) in aqueous solutions were measured respectively. The density functional theory calculations were performed using MN15 functional and PCM solvent model to investigate their structures, as well as the vibrational frequencies and Raman intensities. With the aid of the calculated spectra, all the observed Raman bands of dpTC2− were clearly assigned, with taking into account the deuteration shifts. Moreover, various protonic tautomers of TC− anion were compared in the present theoretical calculations, and 2H-tautomer was found more stable. The experimental Raman spectrum of TC− solution was roughly consistent with the calculated spectrum of the monomeric 2H-tautomer of TC−, but some splits existed for a few bands when compared to the calculated spectra, which might be contributed by the hydrogen-bonding dimers of TC−.
Surface modification of (001) facets dominated TiO2 with ozone for adsorption and photocatalytic degradation of gaseous toluene
Authors: Yang Yue , Wang Zhi-yu , Zhang Fan , Fan Yi , Dong Jing-jing , Sun Song , Gao Chen , Bao Jun
Published: June 2019

This study investigated the positive effect of surface modification with ozone on the photo-catalytic performance of anatase TiO2 with dominated (001) facets for toluene degradation. The performance of photocatalyst was tested on a home-made volatile organic compounds degradation system. The ozone modification, toluene adsorption and degradation mechanism were established by a combination of various characterization methods, in situ diffuse reflectance infrared fourier transform spectroscopy, and density functional theory calculation. The surface modification with ozone can significantly enhance the photocatalytic degradation performance for toluene. The abundant unsaturated coordinated 5c-Ti sites on (001) facets act as the adsorption sites for ozone. The formed Ti–O bonds reacted with H2O to generate a large amount of isolated Ti5c-OH which act as the adsorption sites for toluene, and thus significantly increase the adsorption capacity for toluene. The outstanding photo-catalytic performance of ozone-modified TiO2 is due to its high adsorption ability for toluene and the abundant surface hydroxyl groups, which produce very reactive OH· radicals under irradiation. Furthermore, the O2 generated via ozone dissociation could combine with the photogenerated electrons to form superoxide radicals which are also conductive to the toluene degradation.
Defining 'specialist palliative care': findings from a Delphi study of clinicians
Authors: Forbat Liz , Johnston Nikki , Mitchell Imogen
Published: June 2019

Objective
This study aimed to achieve consensus regarding what distinguishes specialist from non-specialist palliative care to inform service organisation and delivery to patients with life-limiting conditions.

Methods
A three-phase Delphi study was undertaken, involving qualitative interviews and two questionnaire cycles. Thirty-one clinicians (nurses, doctors and social workers) working with a wide range of patients participated in interviews, of whom 27 completed two questionnaire cycles.

Results
Consensus was gained on 75 items that define specialist palliative care and distinguish it from non-specialist palliative care. Consensus was gained that specialist palliative care clinicians have advanced knowledge of identifying dying, skills to assess and manage complex symptoms to improve quality of life, have advanced communication skills and perform distinct clinical practices (e.g. working with the whole family as the unit of care and providing support in complex bereavement). Non-specialist palliative care involves discussions around futile or burdensome treatments, and care for people who are dying.

Conclusions
Areas of connection were identified: clinicians from disease-specific specialties should be more involved in leading discussions on futile or burdensome treatment and providing care to people in their last months and days of life, in collaboration with specialists in palliative care when required.

What is known about the topic?
At present there is no evidence-based definition or agreement about what constitutes specialist palliative care (as opposed to palliative care delivered by non-specialists) in the Australian Capital Territory. An agreed definition is needed to effectively determine the workforce required and its clinical skill mix, and to clarify roles and expectations to mitigate risks in not adequately providing services to patients with life-limiting conditions.

What does this paper add?
This paper offers, for the first time, an evidence-based definition that distinguishes specialist palliative care from non-specialist palliative care. End of life care and bereavement support are not just the remit of specialist palliative care clinicians. Clinicians from beyond specialist palliative care should lead discussions about futile or burdensome treatment.

What are the implications for practitioners?
The findings of this study can facilitate implementation of palliative care strategies by enabling practitioners and patients to distinguish who should be delivering what care.
‘Get off your arse’
Authors: Henderson Barbara
Published: June 2019

Although the UK has a centuries-old history of subversive singing, since the election of a
Conservative-led government in 2010 and imposition of austerity-based economic and social policies, the number
of choirs with a political philosophy and mission has grown. The website CampaignChoirs lists around thirty
political choirs committed to a left-wing, green or anarchist agenda, which is reflected in the music and
related actions. This paper takes as its case study the Leeds-based Commoners Choir and considers how its
musical decisions enable it to communicate protest politics. Using critical discourse analysis, this study
adds to the dialogue on musical discourse by focusing on the speech acts contained within the lyrics; the
social impact of the Commoners’ performances; and the use of dialect to root the works within a distinctly
northern culture. It concludes that careful consideration of discourse can demonstrate a more measurable
authenticity in an artistic act of protest.
Crack deflection in the nonlinear zone of ultra-high-strength steel fatigue crack growth curve
Authors: Xie Xing , He Weiping , Li Guangming , Ke Rui , Wang Yachao , Wu Kaiming
Published: June 2019

The fatigue crack growth rate (FCGR) of 10Ni5CrMoV steel under variable load ratios was investigated. The microscopic observations of growth direction and microstructural analysis were conducted by means of electron backscatter diffraction and transmission electron microscopy. The results showed that FCGR of 10CrNi5MoV steel increased with the increasing load ratio in the mid-growth rate regime; however, it did not completely conform to the Paris Formula. A nonlinear zone existed in the logarithmic coordinate system of the FCGR curve and was unaffected by load ratio. The main impact factors for the appearance of the nonlinear zone were grain size and the size of the plastic zone surrounded fatigue cracks. In the nonlinear zone of the FCGR curve, an apparent crack deflection phenomenon occurred.
The 1968 years: revolutionary politics in Senegal
Authors: Bianchini Pascal
Published: June 2019

In tune with the atmosphere of the ‘global 60s’, Senegal experienced a major political crisis in May 1968 that began with a student strike, followed by the workers in a general strike. May ‘68 in Senegal was both global and local, and these aspects are not in opposition as has sometimes been the case in political and academic debates. The article goes beyond the events themselves and attempts to shed light on a period of ‘revolutionary politics’ that was triggered by the revolt of 1968. This has scarcely been documented, but has had a real influence on contemporary Senegalese politics.
Higher-order assembly of Sorting Nexin 16 controls tubulation and distribution of neuronal endosomes
Authors: Wang ShiYu , Zhao Zechuan , Rodal Avital A.
Published: June 2019

The activities of neuronal signaling receptors depend heavily on the maturation state of the endosomal compartments in which they reside. However, it remains unclear how the distribution of these compartments within the uniquely complex morphology of neurons is regulated and how this distribution itself affects signaling. Here, we identified mechanisms by which Sorting Nexin 16 (SNX16) controls neuronal endosomal maturation and distribution. We found that higher-order assembly of SNX16 via its coiled-coil (CC) domain drives membrane tubulation in vitro and endosome association in cells. In Drosophila melanogaster motor neurons, activation of Rab5 and CC-dependent self-association of SNX16 lead to its endosomal enrichment, accumulation in Rab5- and Rab7-positive tubulated compartments in the cell body, and concomitant depletion of SNX16-positive endosomes from the synapse. This results in accumulation of synaptic growth–promoting bone morphogenetic protein receptors in the cell body and correlates with increased synaptic growth. Our results indicate that Rab regulation of SNX16 assembly controls the endosomal distribution and signaling activities of receptors in neurons.

Mapping tree species diversity is increasingly important in the face of environmental change and biodiversity conservation. We explore a potential way of mapping this diversity by relating forest structure to tree species diversity in Gabon. First, we test the relation between canopy height, as a proxy for niche volume, and tree species diversity. Then, we test the relation between vertical canopy structure, as a proxy for vertical niche occupation, and tree species diversity. We use large footprint full-waveform airborne lidar data collected across four study sites in Gabon (Lopé, Mabounié, Mondah, and Rabi) in combination with in situ estimates of species richness (S) and Shannon diversity (H′). Linear models using canopy height explained 44% and 43% of the variation in S and H′ at the 0.25 ha resolution. Linear models using canopy height and the plant area volume density profile explained 71% of this variation. We demonstrate applications of these models by mapping S and H′ in Mondah using a simulated GEDI-TanDEM-X fusion height product, across the four sites using wall-to-wall airborne lidar data products, and across and between the study sites using ICESat lidar waveforms. The modeling results are encouraging in the context of developing pan-tropical structure-diversity models applicable to data from current and upcoming spaceborne remote sensing missions.

Published: June 2019

This study was conducted to examine well water quality in areas of different land use in Pasir Puteh, Kelantan, Malaysia. A total of four water sampling locations were selected to represent specific land use types, including Pasir Puteh town (urban land use), Padang Pak Amat (industrial land use), Bukit Gedombak (landfill site) and Kampung Jelor (agricultural land use). Well water sampling was carried out twice, in March 2018 and April 2018. Water quality samples were analysed both in-situ and in the laboratory based on the Water Quality Index (WQI) as determined by the Malaysian Department of Environment (DOE). Water quality parameters analysed included Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammonia Nitrogen (NH3N), pH and Total Suspended Solids (TSS). The findings showed that although values of the six parameters observed did not exceed the specified standards, well water quality in all four types of land-use areas belonged to WQI Class III, with values ranging between 61.5 and 74.5. Class III quality indicates that the water should be treated first if it is to be used as drinking water supply. Well water quality in the area subject to agricultural land use exhibited the lowest WQI value of 61.5, reflecting the influence of local rice paddy activities. Continuous monitoring and immediate measures must therefore be undertaken, as these water sources remain exploited by locals for everyday use.

Published: June 2019

Globalization and needs development have provided spaces for women to participate in an economic movement, including those women of fishery laborer families. They perform their roles in order to help the economy without any burden, like the so-called double burden, which is often associated with them since they have to both do households duties and earn money as well. Background and impetus of female economic movement among fishery labour families are the focus of this research. By applying qualitative technique using in-depth interview this study shows that women have a distinct power in a further empowerment of their families. Low education level of these women is not an obstacle in actualizing themselves in the public sectors. In fact, this economic movement had been socialized to them even when they were children. While these women are traditionally restricted within domestic space, they have proved to be a saviour in their families by fulfilling the families’ basic needs, which are often not provided by their husbands. In fact these female fishery workers in Indramayu are the breadwinners for their families. However, the social construct is not fair to them as the society views them merely as freelance workers.

Eastern Bandung Region including Cileunyi, Jatinangor and Rancaekek is a suburb area of Bandung, which has gone through many changes in land use from agrarian to non-agrarian, also the population density and urban growth rate have increased. This phenomenon can lead to urban sprawl and potentially lead to a negative spatial transformation and inefficient resource allocation. This research objectives are to identify the characteristics of urban sprawl development and the pattern of urban sprawl in Eastern Bandung area in 2002, 2010 and 2017. This study uses quantitative approach with descriptive method also spatial analysis technique, scoring, and descriptive analysis. The spatial data that was used are Google Earth image data in 2002, 2010 and 2017. The results of this study show that the characteristics of urban sprawl development that consist of physical and social dimension is high with a score of 2.46. The pattern of urban sprawl can be identified as the combination of ribbon and leap frog development. Ribbon development can be seen in Cileunyi and Jatinangor, meanwhile leap frog development occurs in Rancaekek. The results of this study hopefully can help improve the understanding about urban sprawl and encourage the policy makers in controlling the spatial transformation wisely.

Authors: Dziauddin M F
Published: June 2019

This paper aims to investigate the impact of proximity to the nearest light rail transit station on the value of condominium properties in Greater Kuala Lumpur, Malaysia. The paper utilizes a data set of 476 condominium sales occurring in Greater Kuala Lumpur between January 2017 and the second quarter of 2018. Using a hedonic pricing model, housing price was modelled as a function of proximity to the nearest light rail transit station and with regard to other structural and locational attributes. The results suggest that condominium units located within 800 m to the nearest light rail transit station can earn a premium of MYR 172,904 (US$43,226), or 30% of the city’s average home value. The results of this study also indicate that in determining property values, proximity to the nearest light rail transit station is the second-most influential variable compared to other variables. This paper represents an original contribution to the literature in that there has been limited research on the impact of proximity to light rail transit stations on condominium prices in developing countries.

The using of online transportation application was necessity on urban community. This research aimed at analyses the Influence of the online transportation to the mobility and economic of society, particularly in urban communities such as Bandung, Indonesia which were using GRAB and GO-JEK as online transportation application. The research focus on the existing of GRAB and GO-JEK as the most popular alternative online transportation application for the society compared to the other application, how they affect to the community especially for mobility and economic, and analyses what are the shortcomings of GRAB and GO-JEK that need to be addressed and developed. The method used descriptive and analyzed by using survey and questionnaire, which was distributed directly to the public. Based on the results, GRAB and GO-JEK was the most popular online transportation used by the people of Bandung. The response of the community with the GRAB and GO-JEK was quite good because of the cheap of price, the mobility and economic of society was also increased, people move more often and economic cycle level tend to increase significantly.
Customary Land and the Indigenous People of Sabah: A Case Study of Sinumagang-Tinuman Toki
Authors: Nuar E , Lunkapis G J
Published: June 2019

Customary land is a land that has been inherited from the ancestors and has been cultivated since time immemorial. Customary land is also the foundation of the life of the indigenous communities, and it is governed in accordance with their customs, known as adat. Unfortunately, the customary practices of the indigenous communities are often neglected and are not recognised by the state. This is due to opposing opinions and interpretations of customary land ownership and statutory land tenure as practised by the state. This study was mainly conducted to understand the differing perceptions, with the hope that the findings may provide a enlightenment on how these two opposing systems can be uniformized. A qualitative research method was used involving interviews with key informants from among the indigenous peoples living in Sinumagang and Tinuman Toki, Sabah, Malaysia. The preliminary findings revealed that the current state system does provide a window of opportunity to accommodate input from the customary practices of the indigenous communities to make it a part of the reformed land administration system of the state.

This paper is presented to document a development process of automated system for the spray-painting process and for the purpose of advantage of implementation of automation to the production line instead of manual spray process and know-how of thickness control when applying three spray guns compared to single gun as normally implemented in automated spraying system. Three spraying could reduce the process time to spray the workpieces, in this case, is airplane wing’s parts built from composite material. But these three guns automations system comes with challenging tasks in order to find an even thickness of overlapping spray pattern coming from these three separated guns. Ultimately, various studies on atomization parameters and other factors resulted in successful mass production.

Electromyography is a study of muscle function through the analysis of electrical signals emanated during muscular and muscle contractions. In the post-stroke rehabilitation process, monitoring of muscle activity is very important to know the developments of muscle strength. EMG signals, which produced by muscle activity have information such as muscle contractions, muscle strength and muscle weakness. Rehabilitation process that takes a long period of time can cause muscle fatigue, and the rehabilitation becomes inefficient. The objective of this research is to analyze the muscle fatigue during arm movements by using EMG signals. In this study, deltoid and biceps are monitored by using EMG and the signal are analyzed by using MATLAB. Five healthy subjects are selected to perform the rehabilitation in the experiments. Functional and fundamental movements are used in the data collections. The mean as a feature from a frequency domain is proposed to be used in the analysis. The results show that the signal contractions from deltoid and biceps muscles decreased constantly by the time. In the process of rehabilitation, the stroke sufferers should not do the exercise in a long period of time.

Malaria is a plasmodium parasite disease that affects millions of people in the world every year. Hence, early detection tests are needed to prevent the malaria parasites spread throughout the body. For centuries, manual microscopic blood test remains as the most common method that still being used for malaria detection. However, this procedure contains the probability of miscalculation of parasites due to human error. Computerized system is recognized as a quick and easy ways to analyze a lot of blood samples images by providing direct visualization on the computer screen without the need to examine under the microscope. Therefore, this paper aims to analyze different colour components for improving the parasites counting performance based on thick blood smear images. In this study, five different colour spaces namely YCbCr, RGB, CMY, HSV and HSL have been analyzed and eight colour components which are Y, Cb, R, G, C, M, S and L have been extracted in order to determine which colour component is the best for malaria parasites counting. Overall, experimental results indicate that segmentation using Y component of YCbCr proved to be the best with average counting accuracy of 98.48% for 100 images of malaria thick blood smear.

Published: June 2019

In this paper, a novel method to reduce the number of EEG channels for a Motor Imagery-based Brain Computer Interfaced (BCI) system without compromising its performance is proposed. By reducing the number of EEG channels, the number of features can be reduced and this has to be achieved without sacrificing the classification accuracy and computational time of the BCI. EEG signals were recorded from 10 subjects using a 19-channel EEG amplifier. Higuchi Fractal features were extracted from the recorded signals and modelled using Neural Networks (NN). A simple statistical analysis based on standard deviation was then used for the channel reduction process. The classification accuracy of the NN model formulated with the 19 channels features were compared to that of the model with features selected using statistical method. From the results it was observed that using this approach, the number of EEG channels can be reduced up to 30% without sacrificing its classification performance.
