Published: May 2020

The cause of most projects experiencing delays is the poor quality of the design. One indication of the low quality of design is the change in design at the construction stage. Changes in design at the time of construction cause a decrease in time performance. There have been many studies related to the quality of design, but no one has specifically linked the quality of design to the time performance of project implementation. On the other hand, indicators for measuring the quality of the design have not been the same among the researchers, so it is necessary to re-examine the indicators to measure the quality of the design so that the results reflect the quality of the design that should be. The research was carried out by combining various design quality indicators that had been used by the researchers before, which allegedly influenced the time performance of building construction. The hypothesis proposed was "Improving the Quality of Design will Improve the Performance of the Implementation of Buildings". The object of research is buildings completed in the last 10 years in Indonesia. The data obtained is then tabulated and performed correlation analysis, intercorrelation, factor analysis, determinant analysis, multiple regression analysis, model test and validation. The result is that improving the quality of design will improve performance time and as a design quality determinant is design compatibility.

Published: May 2020

Most of the river in Indonesia has a meander area especially located at the lower reach. Since the pattern of the community behaviour in Indonesia, people live in surrounding or along the river while the river plains and delta consist of alluvial soils, thus, meander migration usually occurs as a response to natural or manmade disturbances of the fluvial system. Meander River in urban area usually encourage sediment transport problem such as riverbed aggradations at the area surrounding inside of the bank then will decrease the river capacity in retaining flood while simultaneously eroding on the outer banks of meander bends. Regarding velocity distribution at the channel cross section, the minimum velocity is occurring on the inside of the meander, therefore some of the sediment loads is deposited. Related with the phenomena, protection against sedimentation and erosion along meandering river extremely needed. Previously, river adjustment within meander area are continually being made, therefore, eventually the gradient of a stream is altered to accommodate the volume of water and the velocity necessary to transport the sediment load. In this paper,understanding of various phenomenon’s in the meander area due to the sedimentation processes are described and propose the new concept of protection with low impact development (LID) approach.

Published: May 2020

Damage to irrigation areas in Indonesia covering an area of 0.37 million hectares for severe damage and an area of 1.25 million hectares for moderate and mild damage, has an impact on Indonesia's ability in rice production; rice imports were almost half a century, and only the adequacy of rice was 2 X, i.e. 1984 and 2009. This was due to low irrigation services which resulted in less optimal carrying capacity of food security. The deterioration in the function of irrigation services can be grouped into 5 causes of low irrigation pillars, namely: vulnerability of water sources, lack of irrigation infrastructure, low irrigationwater management, weak management institutions, and low human resources. The cause will be eliminated by the irrigation modernization program by working on these five pillars. One of the pillars in the modernization of irrigation that needs to be improved is the irrigation management system. The purpose ofthis paper is to contribute ideas in improving the irrigation management system in Indonesia. The author has conducted observations and research on several irrigation areas, both the authority of the Central, Provincial and District Governments, especially visits to DI Wadaslintang, Central Java and DI Bondoyudo, East Java concerning irrigation water management systems. What stands out is the low level of irrigation services due to the inefficient irrigation water management system in Indonesia, in addition to the nature of service-based provision and not service-oriented based on farmers' needs. Identification wascarried out on the DI to find out the reasons for the low irrigation water management system, namely: orientation to water supply, calculation of irrigation requirements, water allocation method, irrigationwater distribution schedule, irrigation water loss, irrigation operational steps, irrigation water productivity measurement This study analyzes the factors causing the low irrigation water management system while making a formula for the improvement proposal in the form of 7 steps.

The foundation of the raft post is the bottom structure of a building that channeled the load from the structure over the soil under it. Carrying capacity of drill pile foundation is influenced by the capacity of the pole tipand bearing capacity of the pole blanket. The decline in this area can be an immediate decline and a decrease in consolidation. This study aims to analyze the decrease of raft poles and the proportion of load bearing in the bogie area of the Kelapa Gading LRT warehouse depot - Jakarta. From the analysis of theNSPT test results in the field, the ultimate carrying capacity and the decrease that occurred on the raft poles were obtained. Based on the results of calculation of the ultimate carrying capacity of a single drill pole of 1.1 x 104 kN and the carrying capacity of the group is 1.1 x 108 kN. Calculation of group efficiency with the Feld method is obtained at a value of 0.588. In the calculation of the immediate decline of the pole, a value of 5 cm is obtained and a decrease in consolidation of 7 cm. From the calculation of the proportion of raft poleload bearing the value of Pr = 6 x 10-6 is obtained, which means that load bearing can be said to be dominated by rafts.

The data that has been collected is then analyzed using descriptive analysis techniques that describe the behaviors that arise during observation. The results showed that the behavior that is often performed by crickets is sounding, eating, climbing, mating and attacking other crickets. Crickets perform sounding behavior to attract the attention of female crickets, show their existence and to defend their territory and food sources. crickets also often climb, to escape from the container because crickets want to live freely. Crickets perform eating behavior to maintain life and will show aggressive behavior when fighting over food and when maintaining their partners. Female crickets will mating if captivated by male crickets.

The development of time-resolved in situ approaches for monitoring mechanochemicaltransformations has revolutionized the field of mechanochemistry. Currently, the established insitu approaches greatly limit the scope of investigations that are possible. Here we develop a newapproach to simultaneously follow the evolution of bulk atomic and electronic structure during amechanochemical synthesis. This is achieved by coupling two complementary synchrotron-basedX-ray methods: X-ray absorption spectroscopy and X-ray diffraction. We apply this method toinvestigate the bottom-up mechanosynthesis of technologically important Au nanoparticles in thepresence of three different reducing agents. Moreover, we demonstrate how X-ray absorptionspectroscopy offers unprecedented insight into the early stage generation of growth species (e.g.monomers and clusters), which lead to the subsequent formation of nanoparticles. Theseprocesses are beyond the detection capabilities of diffraction methods. The approach is general,and not limited to monitoring NP mechanosynthesis. This combined X-ray approach paves theway to new directions in mechanochemical research of advanced electronic materials.
Reaction Landscape and Bioconjugation Profile of Tyrosinase Generated Quinones
Authors: Holder Patrick , ElSohly Adel M.
Published: May 2020

We describe a class of bioconjugation reactions thatenables site-specific modification of proteins throughenzymatic generation of o-quinone from either tyrosineresidues or phenol reagents. The enzymatically generatedo-quinone rapidly reacts chemically with numerouscommon nucleophiles and dienophiles, including thiols,anilines, alkoxyamines, cyclooctynes, and cyclooctenes.Nucleophilic chemoenzymatic reaction with engineeredtyrosine residues creates a hydroxytyrosine (HOT)bridge; a similar reaction with phenols creates a hydroxyphenol(HOP). Diels-alder cycloaddition followingo-quinone generation results in an arylbicyclodiketone (ABCD). The stability of each conjugate againstphysiological pH and temperature varies from less than one day to multiple months in vitro.

Published: May 2020

We synthesized protein-coated gold nanoparticles using green and chemical reduction routes for cellular uptake study. In the current work, we coated gold-aryl nanoparticles of the type AuNPs-C6H4-4-COOH with BSA, collagen, zein and lysozyme proteins. Both routes were carried out without phase-transfer catalysts or extraneous stabilizing agents. High crystallinity of the AuNPs synthesized by the green route can be seen in the transmission electron microscopy images. Osteosarcoma cancer cells are malignant bone tumors with abnormal cellular functions. Studies using MG-63 cells will provide mechanistic suggestions on the details of the amplification in tumors. We studied the cellular uptake of the bioconjugates by MG-63 osteosarcoma cells using laser confocal fluorescence microscopy (LCFM) and flow cytometry. In the LCFM study, BSA-AuNPs was uptaken most efficiently of all protein-coated gold nanoparticles synthesized by the green route. Zein and lysozyme coated nanoparticles, though small sizes, prepared by the green method were not efficiently uptaken by MG-63. The two nanoparticles are negatively charged and zein is also a hydrophobic coat. The difference in hydrophobicity and charge might have affected the internalization. All of those coated nanoparticles that were efficiently uptaken can potentially be used as diagnostic and therapeutic agents for osteosarcoma.

Published: May 2020

Lack of quality data and difficulty generating these data hinder quantitative understanding of reaction kinetics. Specifically, conventional methods to generate transition state structures are deficient in speed, accuracy, or scope. We describe a novel method to generate three-dimensional transition state structures for isomerization reactions using reactant and product geometries. Our approach relies on a graph neural network to predict the transition state distance matrix and a least squares optimization to reconstruct the coordinates based on which entries of the distance matrix the model perceives to be important. We feed the structures generated by our algorithm through a rigorous quantum mechanics workflow to ensure the predicted transition state corresponds to the ground truth reactant and product. In both generating viable geometries and predicting accurate transition states, our method achieves excellent results. We envision workflows like this, which combine neural networks and quantum chemistry calculations, will become the preferred methods for computing chemical reactions.

© 2019, The Author(s). Continental rift systems form by propagation of isolated rift segments that interact, and eventually evolve into continuous zones of deformation. This process impacts many aspects of rifting including rift morphology at breakup, and eventual ocean-ridge segmentation. Yet, rift segment growth and interaction remain enigmatic. Here we present geological data from the poorly documented Ririba rift (South Ethiopia) that reveals how two major sectors of the East African rift, the Kenyan and Ethiopian rifts, interact. We show that the Ririba rift formed from the southward propagation of the Ethiopian rift during the Pliocene but this propagation was short-lived and aborted close to the Pliocene-Pleistocene boundary. Seismicity data support the abandonment of laterally offset, overlapping tips of the Ethiopian and Kenyan rifts. Integration with new numerical models indicates that rift abandonment resulted from progressive focusing of the tectonic and magmatic activity into an oblique, throughgoing rift zone of near pure extension directly connecting the rift sectors.

Published: May 2020

Cardiovascular diseases are the first cause of death globally: more people die annually from these diseases than from any other causes. These diseases are a group of disorders of the heart and blood vessels that appears silently but lead to many serious consequences for life. Vascular diseases including atherosclerosis, aneurysm, peripheral artery disease... affect the arteries, veins, or capillaries throughout the body and around the heart. Therefore, assessment of the quality of blood vessels early is extremely necessary in order to prevent cardiovascular diseases. Bioimpedance analysis is a non-invasive, safe, and low-cost technique that is widely used for diagnosing various diseases. This study conducts a novel method to evaluate the status of the blood vessels in two cases: stenosis and aneurysm based on bioimpedance signals. A 3D model of the forearm with several layers (skin, fat, muscle, bone, and blood vessel) and electrodes is simulated by using Comsol Multiphysics software. The electric impedance in different vascular conditions is examined. The results show that vessel impedance changed substantially because of vascular disorders. The bioimpedance signals vary according to the sizes of plaque and aneurysm wall. Consequently, bioimpedance analysis is reliable to detect vascular diseases and able to be applied in the near future.

Published: May 2020

Cancer can be regarded as a rising threat to modern societies. Detecting cancer at an early stage significantly improves the durability of the disease; unfortunately, currently available methods for early diagnosis of cancer are scarce and inefficient. In fact, the concentration of Volatile Organic Compounds (VOCs) in cancer patients in the breath is different from that in normal people. Therefore, the development of new sensors that can detect VOCs with low concentrations at the early stage of cancer, is desirable. 2D materials are expected as attractive materials for these sensors due to their large surface area to volume ratio. In this work, we investigated the adsorption mechanism of some small-to-medium VOCs on the surface of silicene by the quantum simulation method. The images of the potential energy surfaces for different positions of the adsorbate on the silicene surface were explored by Computational DFT-based Nanoscope for the determination of the most stable configurations and diffusion possibilities. The adsorption energy profiles were calculated by three approximations of van der Waals interaction: revPBE-vdW, optPBE-vdW, and vdW-DF2. It is found that the adsorption energies of the VOCs in question vary in the range of 0.6-1.0 eV, which indicates that silicene is considerably sensitive with these VOCs. The charge transfer between the substrate and VOCs was also addressed.

Published: May 2020

The early diagnosis benefits the greater efficiency of the curing of breast cancer. One of the modalities for the detection of abnormal tissue in the present day is electrical impedance myography (EIM). EIM is a noninvasive electrophysiological technique, using a high frequency, low-intensity electrical current to derive voltage at the positions of sense electrodes. A Comsol Multiphysics-based finite element model was carried out in order to build the 3D model of breast tissue for computational simulation of the mentioned technique. EIM parameters of breast tissue involving resistance, reactance, phase angle in case of malignant tissue were calculated and compared with parameters of normal tissue. The results of the study showed some remarkable effects of tumor sizes, tumor positions, and electrode positions on the EIM parameters, which can be considered for potential early detection.

Published: May 2020

This present work aims to reduce the color of biodiesel from crude palm oil through the application of activated carbon prepared from chili stem waste. Chilli stem was converted into activated carbon using 30 wt% KOH at a ratio of 1:2 for 1 h, followed by carbonization at 500 oC under an N2 atmosphere for a further hour. Physico-chemical characteristics of the raw material and activated carbon were analyzed including thermogravimetric analysis, proximate analysis, and porosities. The results demonstrated that the activated carbon was a porous material with a highly mesoporous structure (84.5%). The surface area of activated carbon was 10.6 m2/g and it exhibited an average pore diameter of 27.25 nm which was suitable for the removal of large highly colored molecules. Batch adsorption experiments were performed to investigate the reduction in color of the biodiesel. Ratios of activated carbon to biodiesel of 0.002 and 0.1 w/v were used in the study. For comparison, the adsorption was also tested against a commercial activated carbon with a surface area of 1,130 m2/g, but lower average pore size of 3.72 nm. The chili stem activated carbon can reduce color by approximately 15% within 24 h and the maximum color reduction was 95% after 96 h for both activated carbon to biodiesel ratios. The color of biodiesel changes from dark red to yellow and eventually resulted in a pale yellow color with longer adsorption times and was deemed more attractive for use. Moreover, commercial activated carbon with its small pore size could not reduce the color, with a maximum reduction of only 3%.

This study examines the: Sleep plays an important role in adjusting the balance of a stressful day since it helps to eliminate toxins and regenerating body energy. However, stressful life leads to sleeping disorders in many people. Lacking sleep causes dangerous health conditions such as cognitive decline, depression, and the most important one is a myocardial infarction. This study aimed at analyzing the sleep of healthy and insomnia subjects based on the characteristics and properties of brain signals. The power spectrum of the Alpha wave and the Delta wave was calculated and demonstrated on the graph for analyzing purposes. Based on the correlation between Alpha and Delta dual wave power spectrum, the condition of subjects was determined. Particularly, for insomnia subjects, the power spectral of Alpha and Delta correlated positively and vice versa. This research had successfully built a user interface for sleep detection using Brain mapping to visualize the power spectrum.

Published: May 2020

Background

In an effort to decrease teenage pregnancies and sexually transmitted diseases, there are discussions on the implementation of a school-based condom availability and distribution policy. However, there is a dearth of information on the extent and range of the empirical evidence supporting this policy initiative. Hence, this study aimed to identify enablers and deterrents of the program to serve as groundwork for health professionals and policy makers toward a more comprehensive adolescent program in the country.

Methods

A scoping review of literature based on the five-stage framework by Arskley and O’Malley was utilized in the study. Two researchers performed a comprehensive search of peer-reviewed literature through PubMed, ScienceDirect, EBSCOhost and ProQUEST published from 1985 to 2016. Inclusion criteria for records were: i) Original research published in a peer-reviewed journal; ii) Focused on school-based condom availability and distribution; iii) Study participants were students in a secondary public or private schools; iv) Published in English language. Two researchers independently appraised each record against the set inclusion criteria. Likewise, independent abstraction of data from selected studies were performed. Disagreements in screening, selection, and abstraction were settled through consensus.

Results

A total of 2,114 records were initially screened for eligibility, of which eight met the inclusion and exclusion criteria. Seven of the studies were conducted in the USA and one study was carried-out in Mexico. Notably, none of the published papers originated in Asia. Four essential themes emerged that reinforces the program: i) establishment of state-level policy; ii) engagement of stakeholders and parents on public dialogue: iii) empowering activities in schools; and iv) increasing condom reach and coverage. On the other hand, four significant barriers were recognized; i) assumption that condom availability and distribution to adolescents promote sexual promiscuity; ii) lack of parental support due to religious and moral concerns and the acceptance of the students to certain programs; iii) discomfort and embarrassment felt in general by the students towards acquiring condoms in schools; and iv) structural barriers such as poor coverage and gender differences among male and female students.

Conclusions

These findings suggest that there have been limited studies conducted on the success and challenges of school-based condom availability program. Although study results have shown substantial benefits of the program, emergence of thematic insights relating to parental support, sexual attitude and behavior, program coverage and structural implications acted as major enablers and deterrents on condom availability and distribution program. It is crucial to recognize these existing issues to generate strategic recommendation and action for improvements of the program.
Supporting the role and enabling the potential of community health workers in Bangladesh’s rural maternal and newborn health programs: a qualitative study
Authors: Adams Alayne M , Vuckovic Myriam , Graul Emily , Rashid Sabina F , Sarker Malabika
Published: May 2020

Background

In the global journey towards Universal Health Coverage (UHC), strong primary healthcare systems are essential. This includes the frontline health workers, the bedrock of which are community health workers (CHWs). In Bangladesh, this largely female workforce plays a critical role in health promotion and linking communities with the formal health care system. With the launch of the new national strategy on CHWs, and its ambitions around the implementation of harmonized systems of financing, certification, job harmonization, performance assessment and supportive supervision, it is important to reference the perceptions, experiences, needs and aspirations of CHWs themselves.

Methods

This qualitative exploratory study examines three UNICEF supported maternal and newborn health (MNH) programs in rural Bangladesh, with two districts sampled for each program. In-depth interviews were conducted with CHWs, community members, other health workers, and program managers. Data were analyzed using a thematic analysis approach, with a particular focus on the voice and experience of CHWs and the programmatic features that support them in serving their communities.

Results

Across all three programs, CHWs function as critical local agents for health promotion and referral whose recruitment from and support by the community, enhances their effectiveness. Regular communication and collaboration between CHWs and public-sector frontline workers were perceived as important in enabling their role in increasing the coverage of essential services. Support for structured systems of training, supervision and monitoring which encompass the support of referral decisions, was also apparent. Of particular note were the needs and aspirations of CHWs regarding work-life balance, job satisfaction and desire for professional development. These concerns emphasize the importance of flexibility in how the CHW workforce is configured such that roles, responsibilities and remuneration are keyed to experience and qualifications, and the dynamic needs and aspirations of CHWs over the life course.

Conclusions

As Bangladesh pursues its UHC agenda, CHWs are pivotal in linking underserved communities to the formal health system. Flexibility in the scope of CHW roles and responsibilities, as well as supportive supervision, regular training and fair remuneration, will optimize their contributions towards UHC and better MNH outcomes.
