Authors: Napisah Khairatun , Annisa Wahida 
Published: June 2020

<strong>Abstrak</strong>. Lahan rawa pasang surut merupakan salah satu agroekosistem potensial untuk pengembangan pertanian, khususnya tanaman pangan. Kendala yang dihadapi antara lain yaitu: kemasaman tanah yang tinggi, ketersediaan unsur hara dalam tanah yang relatif rendah serta kandungan unsur beracun seperti Al, Fe dan H<sub>2</sub>S. Purun tikus (<em>Eleocharis dulcis</em>) merupakan tanaman hiperakumulator lahan rawa pasang surut yang memiliki kemampuan dalam menyerap atau menetralisir unsur-unsur meracun. Purun tikus memang memiliki kemampuan menyerap logam berat sebanyak 1% dari bobot keringnya atau setara dengan 1,560 mg kg<sup>-1</sup> Fe. Secara umum tanaman hiperakumulator mampu mengakumulasi logam mencapai 11 % dari berat kering. Pada kondisi tergenang logam Fe dapat hilang dari larutan tanah melalui beberapa cara antara lain dengan pengendapan, terjerap pada permukaan liat atau Fe<sup>3+</sup> oksida, teroksidasi menjadi Fe<sup>3+</sup>dan terbawa bersama air drainase.<p> </p><p><strong>Abstract</strong>. Tidal swamp land is one of the potential agroecosystem for agricultural development, especially food plants. The found obstacles here are: high acidity of soil, the availability of nutrients in the soil is relatively low and the content of toxic elements such as Al, Fe and H<sub>2</sub>S. Purun tikus (<em>Eleocharis dulcis</em>) is a tidal swamp hyperacumulator plant that has the ability to absorb or neutralize poisonous elements. Purun Tikus has the ability to absorb heavy metals as much as 1% of the dry weight or equivalent to 1.560 mg kg<sup>-1</sup> Fe. In general, hyperacumulator plants are able to accumulate metals reached 11% of dry weight. In the inundated conditions, Fe metal can be lost from the soil solution in several ways, among others by precipitation, absorbed on the clay surface or Fe<sup>3+</sup> oxide, oxidized to Fe<sup>3+ </sup>and carried along with drainage water.</p>

Authors: Rachman Achmad 
Published: June 2020

The main challenge for cultivating upland in semi arid environment as in West Nusa Tenggara, Indonesia is the limited availability of water resources and accelerated deterioration of soil quality. This study evaluated changes in selected soil properties and soil quality 4 years after the implementation of conservation agriculture (CA) practices. The study was conducted at the CA demonstation plots in Gunung Malang Village, Pringgabaya District, East Lombok Regency, West Nusa Tenggara Province. The surface soil texture was loam with slope ranging from 5 to 10%. Two CA Models and one farmer practice (LP) were compared. Within each model three sampling positions were sampled: within the corn planted area (Position A), 0-10 cm from the edge of the corn planted area (Position B), and 10 – 20 cm from the edge of the corn planted area (Position C). Intact soil samples (76 by 40 mm) were taken from the three positions at two depths (100-mm increments) to determine soil physical properties and bulk samples from the surface soil (0 – 15 cm) to determine soil chemical properties in the laboratory. The CA Model had significantly (<em>P</em> &lt; 0.01) lower bulk density (BD), and increase soil organic carbon (SOC) and available P (Av P), while Position had significantly affect only BD. The lowest BD (0.87 ± 0.07 Mg m-<sup>3</sup>) and the highest SOC (1.51± 0.05%) and available pore water (AWC; 18.06 ± 0.76% vol) were found at Position A in CA with permanent pit (PIT). The highest soil quality index was found in Position A followed by Position B and the least was in C indicating that the crop rotation component in CA had relatively small effect on improving soil quality. These results suggested that there is a gradual improvement on soil quality after 4 years of the implementation of conservation agriculture and require longer time than 4 yr to achieve the best soil quality for this semi arid environment

Published: June 2020

As a rule, the wastewater treatment system is not designed to filter substances formed, as a result of beyond design basis accident. The nature of the beyond design basis accident is associated with the shortterm appearance of a clot of these substances in wastewater, determined by the volume of the substance storage tank. Therefore, a rational approach is to divert this portion of the formed substances into a separate branch of the sewage system or sedimentation tanks. The aim of the work is to implement this approach by creating a laser monitoring system for water pollution.The article proposes a system for automatic detection of a clot of emergency discharge of pollutants into the wastewater of an industrial enterprise. The structural diagram of the system and the purpose of its main elements are given. The system should provide clot detection in real time. To ensure this function, a preliminary study is made of the spectral characteristics of all substances that may appear in wastewater in the event of an emergency.Based on these data, the wavelengths of laser radiation in the system are selected. The obtained measurement data from several probes are presented in the form of a lattice function, which is translated into a relative description representing the order relationship matrix on the set of lattice function components. The relative description is invariant to linear changes in the lattice function. The decision to detect any substance from emergency discharges is made based on a comparison of the relative description of the measurements with the standards prepared at the stage of system setup.The article provides an example of the formation of standards for emergency clots from glycerin and allyl alcohol. The graphs of the lattice functions obtained from the IR spectra of emergency discharges of these substances are given; algorithms for constructing a lattice function and comparison of lattice functions. Thus, using the developed mathematical description of the shape of digital signals based on the relative description, the signal of the monitoring curve can be described in the form of a curve of the optical density change of an aqueous medium.

Abstract
Background: Plasmodium falciparum resistance to antimalarial drugs remains to be a major threat to the control of the disease globally. After the deployment of artemisinin-based combination therapy (ACT), there have been reports of reduced sensitivity of the drug to parasite clearance. In Kenya, artemisinin-lumefantrine (AL) is the recommended first-line drug in the treatment of uncomplicated malaria. This study sought to assess the efficacy of AL after its reintroduction in Kenya, a decade later. We assessed clinical and parasitological responses of children under five years in May and November 2015 in Chulaimbo sub-County, Kisumu, Kenya. Method: Patients of ≥6 and ≤60 months of age with confirmed Plasmodium falciparum mono-infection were enrolled in the study. The children were inpatient for close monitoring, they were treated with a standard dose of AL under supervision of a qualified nurse and followed up for 28 days. We monitored treatment adherence and responses. Efficacy of artemether lumefantrine on Plasmodium falciparum was determined.Results: Of the 90 patients enrolled, fourteen (14) were lost to follow-up, with 76 completing the study period. Seventy-five patients 75 (98.7%) cleared the parasitemia within 48 hours while one (1.3%) cleared on day 3. There was 100% clinical and parasitological parasite clearance. Conclusion: Artemisinin lumefantrine was found to be highly efficacious to plasmodium falciparum parasites in children aged ≥6 and ≤60 months. The results reported here indicate that the drug can be used to treat uncomplicated malaria in the study population. However, there is need for continued monitoring of its effectiveness in children and adults to counter the threat of resistance.

Abstract
Background

Uterovaginal prolapse is a significant public health concern in developing countries like Ethiopia where access to health care is limited. It significantly affects women’s health and productivity. Thus, it is very important to identify determinant factors and take preventive actions.
Methods

A hospital based unmatched case-control study was conducted on 86 cases and 258 controls who attended gynecologic outpatient departments in Nekemte town, from May 1 to July 30/2019. Cases were women with utero-vaginal prolapse while controls were women free from utero-vaginal prolapse but with other gynecologic diseases. Data were collected using pretested structured questionnaires and measurement on height and weight were taken to calculate body mass index of women. Data were entered using Epi Data version 3.1 and analysis was carried out by SPSS version 24.0. Descriptive, bivariate and multivariable logistic regressions were performed. Adjusted odds ratio with 95% confidence interval was used and statistical significance was declared at p < 0.05.
Results

This study revealed, age ≥ 40 years (AOR = 10.49; 95%CI: 4.03, 27.35), duration of labor ≥ 24 hours (AOR = 8.32; 95%CI: 3.58, 19.33), instrumental delivery (AOR = 7.40; 95%CI: 1.21, 45.28), non- utilization of family planning (AOR = 3.14; 95%CI: 1.32, 7.47) and underweight (BMI < 18.5 kg/m2) 5.30 (AOR = 5.30; 95%CI: 1.83, 15.33) were determinants of utero-vaginal prolapse.
Conclusion

Age ≥ 40 years, prolonged labor, instrumental delivery, non-utilization of family planning and underweight were identified as determinant factors of utero-vaginal prolapse. Thus, family planning service utilization and appropriate and timely obstetric care are advisable.

Published: June 2020

Abstract
Due to the high stress of Faizabad ridge close to Allahabad city and the absence of strong-motion records for any engineering studies, it is essential to use a stochastic model to study the deterministic earthquake scenario of Allahabad city. The work investigates the effect of stress drop for an earthquake on 30 sites (83 boreholes) located across the city using 1-D seismic site response analysis. The ground motion has been simulated for Allahabad fault using stochastic finite fault model for stress drop ranges from ~70 bar to ~200 bars. Simulation results show the Peak Ground Acceleration (PGA) value of 0.026 g and 0.085 g at 70 and 200 bars stress drops, respectively. Site response results reveal that Indian Standard IS: 1893-2002 underestimates the PGA at higher stress drop compared to the estimated spectral acceleration values. Further, the lower stress drop can give a higher mean spectral acceleration at a long-period. Contour plot of surface-level PGA, low and high period spectral acceleration with response spectra for Allahabad city shows the variation with stress drop.

Abstract
Background: Symptomatic lumbar disc herniation is rarely seen among adolescents. Adolescent lumbar disc herniation (ALDH) accounts for 0.5% to 6.8% of all those treated. Evidently, to our knowledge, no studies have emphasized the operative technique to treat two contiguous level adolescent lumbar disc herniation simultaneously. In this study, we aim to investigate the feasibility and advantages of one-stage full-endoscopic lumbar discectomy（FELD）for two contiguous level ALDH. This is the first paper, to my knowledge, dealing with two contiguous level ALDH simultaneously with one-stage full-endoscopic lumbar discectomy.Methods: Between January 2014 and December 2019, patients received FELD surgery for lumbar disc herniation (LDH) in 2 main minimally invasive spine center of China were selected for screening of this study. Data of 5877 cases were retrospectively analyzed (2780 cases and 3097 cases, respectively). The inclusion criteria were patient under 21-year old, two contiguous level symptomatic lumbar disc herniation received one-stage 2 level PELD surgery. Visual analog scale (VAS) scores and modified Macnab criteria were used to assess the preoperative and postoperative clinical results.Results: 11 patients were enrolled in this study (0.19%,11/5877), 8 patients were male and 3 were female. 9 patients with LDH in the same side underwent single-incision 2 level FELD surgery via transforaminal approach. 2 patients with LDH in different side underwent FELD surgery via combined transforaminal and interlaminar approach. There were no immediate perioperative complications. The visual analog scale (VAS) decreased significantly in both early and late follow-up evaluations and these score demonstrated significant improvement in late follow-up (P <0.01). For the modified MacNab criteria, the final outcome results were excellent in 9 patients (81.8%), good in 1 patients (0.9%), fair in1 patients (0.9%), and the overall success rate was 90.9%.Conclusion: One-stage full-endoscopic lumbar discectomy for 2 level symptomatic ALDH is an effective and less invasive method, which can be considered as an alternative good technique for selected adolescent patients.

Abstract
Background:SARS-Cov-2 infection or COVID-19 is a global pandemic. From the time of identification to till, multiple clinical symptoms and parameters have been identified by the researchers of various countries and regions regarding the diagnosis and presentations of COVID19 disease. In this manuscript, we investigated the primary symptoms and basic hematological presentations of SARS-CoV-2 infection among the Bangladeshi patients. Methodology: We have collected the disease history of mild to moderate degree of COVID19 patients; hematological and biochemical on admission reports of moderate degree COVID19 patients. All of them were tested positive for SARS-CoV-2 by RT PCR in different institutes in Bangladesh. Results: According to this study though COVID19 patients in Bangladesh commonly presented with fever, cough, fatigue, shortness of breath, and sore throat, but symptoms like myalgia, diarrhea, skin rash, headache, Abdominal pain/cramp, nausea, vomiting, restlessness, and a higher temperature of >1000F have a greater presentation rate and more frequent than other published studies. CRP and Prothrombin time was found to increase in all the patients. Serum ferritin, ESR, SGPT, and D-Dimer were found increased among 53.85%, 80.43, 44%, and 25% patients respectively. 17.39% of the patients had leucocytosis and neutrophilia. 28.26% of patients presented with lymphocytopenia. 62.52% of patients had mild erythrocytopenia. Conclusion: Despite some similarities, our study has evaluated a different expression in presenting symptoms in the case of COVID19 patients in Bangladesh. CRP, Prothrombin time, serum ferritin, ESR, SGPT, D-Dimer, erythrocytopenia, and lymphocytopenia can be initial diagnostic hematological findings and assessments for prognosis COVID19 disease. Also, Gender variation has a different scenario of clinical and laboratory appearance in this region.
