Electrochemical Biosensor for Detecting both Pb2+ and Hg2+ in Human Blood
Authors: Sun Chenxi 
Published: October 2024

Many studies have demonstrated that lead ion ( Pb2+ ) and mercury ion ( Hg2+ ) are harmful to human health. Lead was found to accumulate in the kidney, leading to oxidative stress, apoptosis, and inflammation in the nephrons, and possess marked testicular toxicity. Mercury is well-known to produce nephrotoxicity, inflammatory responses and induce oxidative stress and apoptosis. These heavy metals can enter the human body in various ways, such as through skin or inhalation routes, or contaminated drinking water and food. But heavy metal poisoning is not easy to diagnose because existing detecting measures has many disadvantages cause them can’t widely spread. So, seeking an easy way to detect them in human blood to discover lead or mercury poisoning is an unmet need. This paper develops a new reusable biosensor for detecting both Pb2+ and Hg2+ in human blood. This work is based on the reaction between guanine and Pb2+ form of G-quadruplex and Hg2+ connect two thymines together cause the variation of electrochemical signal. The signal is magnified by methylene blue-gold nanoparticles (MB-AuNP) to increase the limit of detection Although the reuse part of sensor is still in theory, but this approach can make the cost of sensor low and create the feasibility of recycle. Overall, providing a new idea to make contributions to the prevention of heavy metal poisoning is the reason why this study is conducted.
Welder Work Position Planning with the REBA Method: Rapid Entire Body Assessment
Authors: Hamzah Hamzah 
Published: October 2024

Welding is a job with a high risk of danger for the welder, such as a hot working environment, dehydration, eye complaints, and uncomfortable working positions. One of the conditions that often occur in welding workers when carrying out work is the position of the welder's body when carrying out welding, which is required to stand. This condition will cause complaints that the welder feels because carrying out the welding process takes a long time. This causes the welder to experience pain in the legs and back and, if done continuously, will trigger long-term illness. The method used in this research is method Rapid Entire Body Assessment (REBA). From the results of manually calculating the REBA method, a score of 2 is obtained, which can be interpreted according to the REBA Classification and Risk Level as low risk. Based on the results of work posture testing on the welding section, the workload of the workers has been reduced from 5 to 2. Therefore, the best position is welding while standing with the body upright; this will help the welder work without injury and has been tested using the REBA method.

Authors: Dyah Auliah Rachma Ruslan  
Published: October 2024

Dalam masyarakat hukum adat Bugis Makassar, terdapat kepercayaan bahwa seorang anak yang lahir dengan wajah sangat mirip dengan salah satu orang tuanya dianggap kurang baik, karena dipercaya dapat membuat anak tersebut sering sakit atau bahkan cepat meninggal. Oleh karena itu, menurut kepercayaan masyarakat Bugis, anak yang sangat mirip dengan orang tuanya harus dijual kepada orang lain untuk menghindari hal-hal buruk. Penulisan jurnal ini bertujuan untuk menganalisis lebih lanjut dari sudut pandang hukum nasional terkait tradisi menjual anak dalam masyarakat Bugis, khususnya apakah makna "menjual" dalam tradisi tersebut sama dengan konsep jual beli sebagaimana diatur dalam Pasal 1457 KUH Perdata, dan apakah ada implikasi hukum dari tradisi tersebut. Penelitian ini menggunakan metode penelitian hukum normatif dengan pendekatan undang-undang. Sumber bahan hukum yang digunakan meliputi bahan hukum primer dan sekunder, yang dikumpulkan melalui studi pustaka dan dianalisis secara kualitatif serta disajikan secara preskriptif. Dalam tradisi menjual anak di masyarakat Bugis Makassar, tidak ada transfer tanggung jawab, karena anak tetap berada di bawah asuhan orang tuanya. Tradisi ini tidak dapat dianggap sebagai perjanjian jual beli yang sah menurut hukum, karena bertentangan dengan ketentuan objek perjanjian. Tradisi ini hanya merupakan bagian dari adat istiadat setempat yang dipercaya dapat mencegah hal-hal buruk, tanpa menimbulkan akibat hukum.

Service quality has been one of the important parameters when we try to achieve the patient satisfaction index. Organizations imparting services particularly related to patient care majorly focus on its quality. Quality of delivery of services is an utmost important tool. Every patient or an attendant of the patient has some perception in his mind or expectation when he visits a hospital regarding the treatment and care provided. If there is a major gap between the service delivery and quality of services, the outcome of the services will be dissatisfaction. If there is no major gap between the two or the quality of services provided meets more than their expectations, the outcome of the services will be highly satisfactory. In this study, a comparative analysis has been done between the two major private hospitals of the Raipur City of Chhattisgarh. The data is primary, and it is collected from the OPD follow-up, indoor patients, and the attendants who visited the hospitals and stayed at least three days for their treatment. (Word count: 170).

Published: October 2024

Although rоutinе pesticide analysеs are mostly performed using GC-MS, GC-MS/MS and/or LC-MS/MS, some pesticides especially those with relatively high MRLs and good detector response could also be precisely quantified with less sensitive equipment which gives the opportunity to some laboratories to expand their scope of work. The study focuses on HPLC-DAD method development for detection of folpet in barley grain. QuEChERS method was performed for extraction after which, additional clean-up was performed using PSA and polypropylene filtration. Pesticide separation was achieved using mobile phase of acidified CAN (pH 2.5) and water. The initial mobile phase was 60:40% (v/v), the elution gradient starts from 80:20% (v/v) to 100:0% (v/v) in 7 min and holds 100:0% (v/v) up to 8.5 min at a flow rate of 1 ml/min after which in the next 6.5 min the column was re-equilibrated to 40% phase-B.
Calibration was performed using matrix-matched calibration standards. The obtained limits of detection (LOD) and quantification (LOQ) were 0.18 and 0.55 mg/kg, respectively, and the linear regression coefficient was 0.9973. Recovery, repeatability and reproducibility were investigated at three fortification levels (0.1 mg/kg, 0.6 mg/kg, and 1.6 mg/kg) and were found acceptable with relative standard deviation less than 10%. The method was applied for the analysis of three barley grain samples obtained from different producers and showed that folpet was present in one sample below the LOQ. Overall, the developed method is suitable for the determination of folpet in barley grains at levels below the established MRL of 1 mg/kg.

While studies on the incidence of flooding exist in several parts of Cameroon, very little empirical evidence has been reported for highly dynamic and urbanizing landscapes in Cameroon. Yet, micro level evidence on flooding and their development planning implications are required to advance theory building in the frame of development planning and hazard mitigation in rapidly urbanizing contexts. This paper bridges the knowledge gap by using the case of Santchou, a highly dynamic landscape, to: (a) analyse the spatio-temporal variations in flood incidence, (b) determine the drivers of flood occurrence, and (c) examine their sustainable development planning implications. To achieve these objectives, a representative sample of 141 households was conducted in five communities within the study area. This was complemented by key informant interviews (n=8) and field observations. Data was collected using the Kobo Collect tool. The collected data was analysed descriptively and presented as tables and bar charts, with the aid of the Statistical Package for Social Sciences (SPSS version 25). Cartographic data was analysed spatially and presented using maps. Based on the findings, the following conclusions were derived: Firstly, flood occurrence vary spatially in terms of severity, with very high intensity in the south east; this decreases towards the north west and western sections of the study area. Flood occurrence also vary over time with the peak of occurrence observed in the month of July and August which corresponds to the peak of the rainy season. Secondly, the most significant effects of floods include; the destruction of physical installations such as houses, household items. Floods equally affect human activities through the destruction of crops, livestock and the disruption of transport circulation. Furthermore, flood effects are less severe in Santchou Ville and Albatross neighborhoods compared to neighborhoods such as; Madagascar, Bessouck and Kassala Farm. Thirdly, while planning approaches exist at household, neighborhood and municipality levels, the most effective involves the use of sandbags and the cleaning of water channels. This study recommends that, sustainable development planning measures currently implemented at the household, neighborhood and municipal levels should be encouraged by the state and civil society organizations such as NGOs. Additionally, sustainable development planning measures should be implemented alongside proactive measures such as; flood alert signals, and the resettlement of inhabitants to safer areas. Future studies should assess the effectiveness of flood management approaches in the study area.

Aims: This study aimed to study the resistance profile of Klebsiella species to antibiotics, highlighting their resistance phenotypes at the Yaoundé University Teaching Hospital (YUTH).
Study Design: We carried out a retrospective and prospective study.
Place and Duration of Study: Bacteriology unit, Yaoundé University Teaching Hospital, from January 2010 to December 2020.
Methodology: Antibiotic susceptibility testing (AST) was performed using the Kirby-Bauer disc diffusions method on Muller Hinton agar according to the AST committee of the French Society of Microbiology (CASFM, 2020). The data was digitized and analyzed using descriptive statistics to understand the antibiotic resistance patterns of Klebsiella species.
Results: During this study, we identified 589 strains of Klebsiella species. Klebsiella pneumoniae pneumoniae was the most frequent sub-specie identified (64.69%). Blood and urine specimens were the samples that were frequently encountered. Children under 10 and adults over 60 were the most infected groups of patients. The majority of the samples analysed came respectively from the Intensive Care Units (21.22%), Paediatrics (14.60%), and Medicine (12.56%). The Klebsiella species isolated showed a high resistance rate to beta-lactams (72%), phenolics (62.30%), and quinolones (60.41%). Over the years, we have observed a gradual decline in the resistance rate to aminoglycosides, going from 87.80% in 2010 to 11.11% in 2020 with amikacin, which remains the most active. Resistance to colistin, which is one of the last therapeutic resort antibiotics, showed very alarming resistance rates of 63.63% with low rates in 2016 (0%) and 25% in 2018. Klebsiella species retained good sensitivity to the piperacillin-tazobactam, as well as to imipenem and nitrofurantoin with low resistance rates for these last two antibiotics (8.33% and 15% respectively).
Conclusion: Based on our findings, which indicate a significant level of resistance among Klebsiella species to commonly prescribe antibiotics, it is crucial for both the health authorities in Cameroon and specifically at the YUTH to take prompt actions.

AbstractThe Interior Exploration using Seismic Investigations, Geodesy and Heat Transport mission, to be launched in 2018, will perform a comprehensive geophysical investigation of Mars in situ. The Seismic Experiment for Interior Structure package aims to detect global and regional seismic events and in turn offer constraints on core size, crustal thickness, and core, mantle, and crustal composition. In this study, we estimate the present‐day amount and distribution of seismicity using 3‐D numerical thermal evolution models of Mars, taking into account contributions from convective stresses as well as from stresses associated with cooling and planetary contraction. Defining the seismogenic lithosphere by an isotherm and assuming two end‐member cases of 573 K and the 1073 K, we determine the seismogenic lithosphere thickness. Assuming a seismic efficiency between 0.025 and 1, this thickness is used to estimate the total annual seismic moment budget, and our models show values between 5.7 × 1016 and 3.9 × 1019 Nm.
Geoelectrical Signatures of Reactive Mixing: A Theoretical Assessment

Published: February 2018

AbstractCharacterizing the effects of subsurface fluid mixing on biogeochemical reactions is a key step toward monitoring and understanding a range of processes and applications in which fluids of different chemical compositions mix, such as aquifer remediation, CO2 sequestration, or groundwater‐surface water interactions. Yet the development of noninvasive methods to monitor mixing processes remains an outstanding challenge. Mixing processes are controlled by concentration gradients that develop at scales below the spatial resolution of hydrogeophysical imaging techniques. To overcome this difficulty, we propose to focus on the geoelectrical response of mixing‐driven chemical reactions, for which the products are electrically more conductive than the background solution. For such reactions, we investigate the impact of reactive mixing on the resulting effective electrical conductivity. The transport equations are solved using the Lamellar Mixing Theory for a range of velocity gradients representative of the stretching rates experienced by mixing fronts in heterogeneous porous media. Focusing on simple shear flows, we demonstrate that such reactions may result in substantial changes (several orders of magnitude) in the effective conductivity over time, thus providing geoelectrical signatures of reactive mixing dynamics. The temporal evolution of the effective conductivity depends on the relative orientations of the applied electrical potential gradient, mean flow, and velocity gradient, yielding different sensitivities to dispersion processes, stretching rates, and reaction kinetics. These results suggest that the use of chemical reactions with electrically conductive products could help to overcome present limitations of time‐lapse geophysical imaging in the monitoring of the spatiotemporal dynamics of subsurface reactive mixing processes.
Vulnerability of Southeast Greenland Glaciers to Warm Atlantic Water From Operation IceBridge and Ocean Melting Greenland Data

Published: February 2018

AbstractWe employ National Aeronautics and Space Administration (NASA)'s Operation IceBridge high‐resolution airborne gravity from 2016, NASA's Ocean Melting Greenland bathymetry from 2015, ice thickness from Operation IceBridge from 2010 to 2015, and BedMachine v3 to analyze 20 major southeast Greenland glaciers. The results reveal glacial fjords several hundreds of meters deeper than previously thought; the full extent of the marine‐based portions of the glaciers; deep troughs enabling warm, salty Atlantic Water (AW) to reach the glacier fronts and melt them from below; and few shallow sills that limit the access of AW. The new oceanographic and topographic data help to fully resolve the complex pattern of historical ice front positions from the 1930s to 2017: glaciers exposed to AW and resting on retrograde beds have retreated rapidly, while glaciers perched on shallow sills or standing in colder waters or with major sills in the fjords have remained stable.
Wettability and Flow Rate Impacts on Immiscible Displacement: A Theoretical Model
Authors: Hu Ran , Wan Jiamin , Yang Zhibing , Chen Yi‐Feng , Tokunaga Tetsu 
Published: February 2018

AbstractWhen a more viscous fluid displaces a less viscous one in porous media, viscous pressure drop stabilizes the displacement front against capillary pressure fluctuation. For this favorable viscous ratio conditions, previous studies focused on the front instability under slow flow conditions but did not address competing effects of wettability and flow rate. Here we study how this competition controls displacement patterns. We propose a theoretical model that describes the crossover from fingering to stable flow as a function of invading fluid contact angle θ and capillary number Ca. The phase diagram predicted by the model shows that decreasing θ stabilizes the displacement for θ≥45° and the critical contact angle θc increases with Ca. The boundary between corner flow and cooperative filling for θ < 45° is also described. This work extends the classic phase diagram and has potential applications in predicting CO2 capillary trapping and manipulating wettability to enhance gas/oil displacement efficiency.
Autocorrelation of the Seismic Wavefield at Newberry Volcano: Reflections From the Magmatic and Geothermal Systems
Authors: Heath Benjamin A. , Hooft Emilie E. E. , Toomey Douglas R. 
Published: February 2018

AbstractWe show that seismic autocorrelations provide new depth constraints on upper crustal magmatic systems. Autocorrelations of both ambient noise recorded on seismometers and geophones and teleseismic earthquake coda recorded on seismometers elucidate the structure of Newberry Volcano. These autocorrelations result in the two‐way, body wave Green's function beneath a station. Within the caldera, a reproducible, coherent P wave reflection is inferred to come from the top of a magma body at ~2.5 km depth and maps with the lateral extent of an anomalously low‐velocity body imaged tomographically. On the west flank of the volcano, a reflection that deepens with distance from the caldera is inferred to result from a temperature‐dependent change in metamorphic facies and may map the thermal structure of the edifice. Our results show that the autocorrelation of diffuse seismic energy reconstructs reflections from seismically sharp boundaries associated with the upper crustal magmatic structure.
Relation of Field‐Aligned Currents Measured by the Network of Iridium® Spacecraft to Solar Wind and Substorms
Authors: McPherron R. L. , Anderson B. J. , Chu Xiangning 
Published: February 2018

AbstractThe strength of field‐aligned currents coupling the magnetosphere to the ionosphere was obtained by the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) using the network of Iridium® spacecraft. The distribution of current was integrated giving total current in and out of the ionosphere on the dayside and nightside of the Earth in both hemispheres. The onset of auroral zone negative bays and midlatitude positive bays corresponds to an increase in nightside upward current. The total outward current tends toward saturation with increasing solar wind driver strength. The optimum solar wind coupling function for AL index predicts ~73% of the variance in nightside upward current. The dayside and nightside predictors of upward current rise to a peak at 30–45 min and decay slowly over 2.5 hr. Nightside response is delayed relative to dayside.
Multiscale Dynamics of Aseismic Slip on Central San Andreas Fault
Authors: Khoshmanesh M. , Shirzaei M. 
Published: February 2018

AbstractUnderstanding the evolution of aseismic slip enables constraining the fault's seismic budget and provides insight into dynamics of creep. Inverting the time series of surface deformation measured along the Central San Andreas Fault obtained from interferometric synthetic aperture radar in combination with measurements of repeating earthquakes, we constrain the spatiotemporal distribution of creep during 1992–2010. We identify a new class of intermediate‐term creep rate variations that evolve over decadal scale, releasing stress on the accelerating zone and loading adjacent decelerating patches. We further show that in short‐term (<2 year period), creep avalanches, that is, isolated clusters of accelerated aseismic slip with velocities exceeding the long‐term rate, govern the dynamics of creep. The statistical properties of these avalanches suggest existence of elevated pore pressure in the fault zone, consistent with laboratory experiments.
