MATERIAL FLOW ANALYSIS DALAM EVALUASI KUALITAS AIR BUDIDAYA IKAN NILA DENGAN 1 TEKNIK AKUAPONIK
Authors: Suciati Fuzi , Aviantara Dwindrata 
Published: February 2021

Pertambahan populasi penduduk menyebabkan pengurangan lahan pangan. Namun kebutuhan pangan semakin meningkat dengan pertumbuhan populasi manusia. Situasi tersebut diperparah dengan kegiatan antropogenik yang berdampak kepada penurunan kualitas lingkungan yang pada akhirnya menurunkan kualitas pangan yang dihasikan. Pendekatan Material Flow Analysis (MFA) digunakan untuk memperkirakan pengaruh pengelolaan pakan ikan nila (P0 = Pemberian setiap hari pakan, P1 = Pemberian satu hari pakan – satu hari puasa, P2 =Pemberian dua hari pakan – satu hari puasa dan P3 = Pemberian tigahari pakan – satu hari puasa) terhadap mutu air bekas budidaya. Darihasil perhitungan diperoleh skenario P3 memberikan rasio terkecilkebutuhan pakan terhadap bobot ikan total saat panen. Hal inimenyebabkan penurunan mutu air kolam budidaya ikan lebih lambat daripada skenario lain sehingga kekerapan pergantian air menjadi lebih jarang. Kebutuhan volume air budidaya ikan nila dengan skenario P3 adalah paling sedikit, yakni 25% dari kebutuhan air yang menggunakan teknik business as usual, yakni P0. Dengan skenario P3 air bekas budidaya ikan nila memiliki potensi untuk digunakan dalam budidaya tanaman tomat secara hidroponik. Potensi panen tomat adalah dua kaliberdasarkan konsentrasi fosfor. Meski demikian, dari sudut pandang perolehan biomassa ikan pada saat panen, terdapat kelemahan skenario P3. Dalam hal ini skenario P1 memberikan bobot ikan total paling besar pada saat panen.

Published: February 2021

Kegiatan yang berkembang di sepanjang Sungai Batang Toru akan berpengaruh terhadap kualitas air sungai, karena limbah buangan dari kegiatan tersebut sebagian besar langsung dibuang disungai dan hanya sedikit yang mengolah air limbah sebelum dibuang di sungai seperti air limbah dari Perusahaan tambang emas Martabe. Penelitian ini bertujuan untuk analisis kualitas air di ruas Sungai. Batang Toru dengan metoda STORET dan Indeks Pencemaran (IP) seperti yang tercantum dalam Keputusan Menteri Negara Lingkungan Hidup No. 115 tahun 2003. Data parameter kualitas air berasal PT Agincourt Resources (PTAR) yang merupakan hasil pemantauan terhadap 6 lokasi dengan pengambilan data pada periode tahun 2017-2019. Parameter yang dipantau dalam penelitian ini sesuai dengan Keputusan Menteri Lingkungan Hidup Nomor 202 Tahun 2004 yaitu pH, TSS, CN free, As, Cd, Cr, Cu, Fe, Pb, Hg, Ni dan Zn. Data hasil analisis kualitas air di laboratorium akan dibandingkan dengan baku mutu di PP Nomor 82 Tahun 2001 untuk peruntukan air kelas II dan hasilnya menunjukkan bahwa 11 parameter memenuhi baku mutu dan hanya konsentrasi TSS yang sebagian besar tidak memenuhi baku mutu tersebut. Berdasarkankan perhitungan dengan metodeSTORET didapat skor bernilai – 8 di semua lokasi sampling maka disimpulkan di ruas sungai Batang Toru lokasi BT1, BT2, BT3, BT4, BT5 dan BT6 tercemar ringan. Perhitungan dengan metode IP terhadap kualitas air di ruas sungai Batang Toru lokasi BT1, BT2, BT3, BT4, BT5 dan BT6 adalah cemar ringan. Kedua metode ini mempunyai kesamaan hasil yaitu kualitas air di ruas sungai Batang Toru telah tercemar ringan.
Production of Culex pipiens in Stormwater and Combined Sewer Catch Basins

Published: February 2021

ABSTRACT
Man-made stormwater and sewage infrastructure, particularly roadside catch basins, provides widespread habitats for immature mosquitoes in urban and suburban environments. Historically, throughout much of the USA, stormwater, sewage, and industrial wastewater were conducted together through “combined” sewer systems, discharging a combination of stormwater and wastewater into streams. Within recent decades, many cities have replaced these combined sewers with “stormwater only” systems that separate stormwater from wastewater. The objective of this research was to evaluate the implications of this infrastructure conversion for production of Culex pipiens, a primary vector for West Nile virus. On a weekly basis over 14 wk, 20 catch basins (10 combined sewer and 10 stormwater only) were sampled for mosquito larvae and emerging adults using the dipping collection method and floating emergence traps. Abundance of larval Cx. pipiens was higher in combined sewer compared with stormwater-only catch basins, while to the contrary, abundance of adult Cx. pipiens was lower in combined sewer compared with stormwater-only catch basins. This study is the first to reveal that habitat attractiveness and quality for Cx. pipiens may vary between combined sewer and stormwater-only catch basins, and our results contribute to a growing body of research to inform vector management and urban planning efforts as municipalities consider the environmental and public health implications of conversion from combined sewage management to separation of stormwater and wastewater.

Published: February 2021

ABSTRACTThe shape and color of an ovitrap affect the sampling efficiency of mosquitoes. We examined the effect of perforated lids of different colored cups on the preference of Aedes aegypti and Ae. albopictus for oviposition containers. The mosquito species were collected from Tuy Hoa City, Phu Yen Province, Vietnam in April 2016. Females of both species laid eggs in cups without a lid in the order of black, red, and green. However, the number of eggs laid by both species was not different between the black cups with a perforated lid and those without a lid. Aedes aegypti females laid more eggs in red cups with a perforated lid than cups without a lid. Green cups with a perforated lid were not preferred by Ae. aegypti and Ae. albopictus. Our results showed that the effect of perforated lids on oviposition preference was dependent on cup color and that it differed between the mosquito species. Out study provides valuable insights for the development of more effective ovitraps for Aedes mosquito surveillance and control.
Aeromobilities of Student Newcomers in Francophone African Fiction
Authors: Toivanen Anna-Leena 
Published: February 2021

Abstract
In the field of postcolonial literary studies, representations of concrete forms of mobility have not received the critical attention they deserve. This is partly due to the field's reductive understanding of “mobility” as a synonym for migration. In order to enhance dialogue between postcolonial literary studies and mobilities research, this article focuses on representations of aeromobility in the context of Afroeuropean student mobilities in a set of Francophone African novels from the 1980s to the 2010s. My reading of scenes of aeromobility in the text corpus draws attention to the anxious aspects of the air travel of unaccustomed travelers and African newcomers traveling to the former colonial center, and explores the formal functions of representations of aeromobility in terms of narrative structures and tropes.

Authors: Mishra Monika 
Published: February 2021

Background: The nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most frequently used drugs to treat pain and inflammation. Although NSAIDs are having enormous clinical use, but are not devoid of adverse drug reactions (ADRs) as peptic ulcer, gastritis, renal, neurological reactions etc.
Methods: Total 500 Orthopaedic out-patients of SIMS, Hapur were enrolled in the study to observe the risk of ADRs due to NSAIDs. All the ADRs were further analysed in relation to age, sex, types of drug and its pattern etc. The causality was analysed by using Naranjo’s Algorithm and severity was analysed by using the Hartwing and Siegel scale.
Results: In this study the incidence rate of the ADRs was around 5.6%. Among the 28 patients who had developed ADRs, a total 10 kinds of ADRs were observed. The reactions that affected the study subjects were gastritis, nausea, vomiting, abdominal Pain, diarrhoea, urticaria, pruritus, headache, rash, ankle oedema and dizziness. Majority (23 cases) of ADRs were mild in their severity and that 5 cases ADRs were moderate in nature. All the ADRs were treated symptomatically by using standard treatment protocols.
Conclusion: In this study, incidence of adverse reactions to nonsteroidal anti-inflammatory drugs was 5.60% and the most common implicated drug for the ADRs were Diclofenac sodium. Most of the adverse effects were mild and tolerable.

Evaluating the Effect of Asymmetric Cross-section in Free Vibration and Bending Analysis Results of FG Sandwich Beam by Proposing Simple Efficient Element
Authors: Yaghoobi Majid , Sedaghatjo Mohsen , Alizadeh Reyhaneh , KARKON Mohammad 
Published: February 2021

In this paper, the asymmetric effect of the cross-section on the free vibration and bending analysis of FG sandwich beams are evaluated. For this purpose, a simple, efficient element is formulated. The new element is created based on the Timoshenko beam theory. The third- and second-order polynomials will be used for vertical displacement and rotation fields, respectively. The proposed formulation will be written based on satisfying the equilibrium equation. Satisfying the equilibrium equation of the Timoshenko beam, in addition to increasing element efficiency, will reduce the number of nodal unknowns. Several benchmark tests with different boundary conditions are used for thin and thick beams to prove the efficiency of the proposed element. The responses of the good elements of other researchers have been used for comparison. Numerical tests prove the rapid convergence rate and high accuracy of the proposed element in free vibration and bending analysis of the beams with various cross-section types and different boundary conditions. The pinned-sliding support conditions for the beam are used to evaluate the asymmetric effect of the cross-section. The use of asymmetric cross-sections creates additional axial displacements and intensifies the deflection of the beam under the lateral load. By increasing the asymmetry, the additional axial displacement and vertical displacement increase. These additional deflections for thin beams are more than thick ones. Also, asymmetry results in increasing the natural frequencies of beams. In the free vibration analysis, the effect of asymmetry on thick beams is more than thin ones.

Published: February 2021

PurposeCraniopharyngiomas (CPs) are benign tumors, complete tumor resection is considered to be the optimal treatment. However, although histologically benign, the local invasiveness of CPs commonly contributes to incomplete resection and a poor prognosis. At present, some advocate less aggressive surgery combined with radiotherapy as a more reasonable and effective means of protecting hypothalamus function and preventing recurrence in patients with tight tumor adhesion to the hypothalamus. Hence, if a method can be developed to predict the invasiveness of CP preoperatively, it will help in the development of a more personalized surgical strategy. The aim of the study was to report a radiomics-clinical nomogram for the individualized preoperative prediction of the invasiveness of adamantinomatous CP (ACPs) before surgery.MethodsIn total, 1,874 radiomics features were extracted from whole tumors on contrast-enhanced T1-weighted images. A support vector machine trained a predictive model that was validated using receiver operating characteristic (ROC) analysis on an independent test set. Moreover, a nomogram was constructed incorporating clinical characteristics and the radiomics signature for individual prediction.ResultsEleven features associated with the invasiveness of ACPs were selected by using the least absolute shrinkage and selection operator (LASSO) method. These features yielded area under the curve (AUC) values of 79.09 and 73.5% for the training and test sets, respectively. The nomogram incorporating peritumoral edema and the radiomics signature yielded good calibration in the training and test sets with the AUCs of 84.79 and 76.48%, respectively.ConclusionThe developed model yields good performance, indicating that the invasiveness of APCs can be predicted using noninvasive radiological data. This reliable, noninvasive tool can help clinical decision making and improve patient prognosis.

Published: February 2021

Background: Birth cohorts provided essential knowledge for clinical and public health decision-making. However, little is known about retention and determinants of attrition in these specific longitudinal studies, although characterizing predictors of attrition sets the path to mitigate its occurrence and to promote valid inferences. We systematically reviewed retention in follow-ups of birth cohorts of very preterm or very low birth weight infants and the determinants of attrition. PROSPERO registration number: CRD42017082672.Methods: Publications were identified through PubMed®, Scopus, Web of Science, and Cochrane Library databases from inception to December 2017. Studies were included when reporting at least one of the following: retention at follow-ups, reasons for attrition, or characteristics of non-participants. Quality assessment was conducted using the completeness of the report of participation features in the articles. Non-participant's characteristics were presented using descriptive statistics. Local polynomial regression was used to describe overall retention trends over years of follow-up.Results: We identified 57 eligible publications, reporting on 39 birth cohorts and describing 83 follow-up evaluations. The overall median retention was 87% (p25–p75:75.8–93.6), ranging from 14.6 to 100%. Overall, retention showed a downward trend with increasing child age. Completeness of retention report was considered “enough” in only 36.8% of publications. Considering the 33 (57.9%) publications providing information on participants and non-participants, and although no formal meta-analysis was performed, it was evident that participants lost to follow-up were more often male, had foreign-born, multiparous, and younger mothers, and with a lower socioeconomic status.Conclusion: This systematic review evidenced a lack of detailed data on retention, which may threaten the potential use of evidence derived from cohort studies of very preterm infants for clinical and public health purpose. It supports the requirement for a standardized presentation of retention features responding to current guidelines.

Numerical simulation of the piezoresistive effect of βGa2O3 in the <010> direction
Authors: Takahashi Naoki , Sugiura Takaya , Sakota Ryohei , Nakano Nobuhiko 
Published: February 2021

Abstract

β-Ga2O3 has a high potential for power device applications because of a high Baliga’s figure and the availability of large-scale wafers. However, the piezoresistive effect of β-Ga2O3 has not been investigated in detail, and its piezoresistive coefficient has not been reported. This study evaluates the piezoresistive coefficient of β-Ga2O3 in the <010> direction using a mechanical stress simulator and a device simulator, which includes our piezoresistive effect model. In this study, the piezoresistive effect model and simulation method are applied to β-Ga2O3 for the first time. The piezoresistor model of β-Ga2O3 is simulated to evaluate the piezoresistive coefficient of β-Ga2O3. The experimentally obtained gauge factor with and without the contact effect is −5.8 and −3.6, respectively. The piezoresistive coefficient with and without the contact effect is −2.0 × 10−11 Pa−1 and −1.2 × 10−11 Pa−1, respectively. The piezoresistive coefficient is used to evaluate the piezoresistive effect at 1000 °C through thermal analysis.
