Arsenic as an Indicator of Black Shale Assimilation by Nickel-Bearing Mafic-Ultramafic Intrusions, Muremera-Rujungu, Burundi
Authors: Evans David M. , Songore Tharcisse , Ntungwanayo Joël 
Published: March 2022

Abstract
The Muremera-Rujungu Ni-Cu sulfide mineralized chonolithic bodies are part of the well-endowed East African nickel belt of mafic-ultramafic intrusions in central-east Africa, dating from 1390 ± 10 Ma. Associated with the small, pod-like to tubular mineralized mafic-ultramafic intrusions is a suite of thin but extensive mafic sills that have geochemical patterns very similar to those of the marginal rocks of the chonolithic bodies (and are therefore assumed to be cogenetic) but that are generally unmineralized. The sills intrude pyrrhotite-rich phyllites (metasiltstones) that overlie a thick package of graphitic andalusite mica schists and quartzites (carbonaceous mudstones and sandstones) that are regionally enriched in As and Sb. The studied sills vary from 1 to 12 m thick, and they are distinctly differentiated into a coarse acicular-textured upper part of broadly gabbroic to quartz gabbroic composition and a granular, melanocratic pyroxene cumulate lower part, containing trace amounts of blebby sulfide and euhedral chromite. The geochemistry of the sills is typical of crustally contaminated high-Mg basaltic magma and is notable for the depletion of all chalcophile elements relative to primitive mantle melts. The chalcophile metals can be divided into two groups showing different behaviors: Cu, Bi, and Te follow S, which is preferentially concentrated in the upper, fractionated part of the sills, whereas Ni, Pt, and Pd follow As and Sb in being concentrated in the lower, cumulate part. Comparison of Ni/Cr and Ni/Mg ratios shows that this concentration of Ni exceeds that expected from accumulation in cumulus pyroxenes or chromite. The strong correlation of Ni (and to a lesser extent Pt and Pd) with As in the sills suggests a primary control by accumulation of small amounts of Ni-S-As liquid in the basal parts of the sills. We conclude that the parental magma of the sill became saturated in an immiscible S-As liquid by passing through the As-rich carbonaceous shales below and had most of its chalcophile elements stripped out by accumulation of this liquid at lower levels in the mineralizing system. Some of this early, As-rich mineralization was then reentrained by later batches of magma and incorporated into larger, composite chonolith-hosted mineralization such as at Kabanga North in Tanzania. This finding may have relevance for the methodology of future exploration in the East African nickel belt.

The specific location fertilization or in situ fertilization rate is a dynamic application and management method dynamically adapted to the plant’s need according to location and season related to soil chemical properties and aims to increase farmer profit. This greenhouse experiment aimed to evaluate the NPK fertilizer dose based on in situ soil chemistry of tidal swamp compared to NPK recommendation combined with cow manure from the local farm. These pot experiments were conducted from June to October 2019 in a Greenhouse of Soil Science Department, Faculty of Agriculture, Sriwijaya University, Indralaya, Ogan Ilir of South Sumatra. This experiment used a factorial completely randomized design with two factors and three replications. The first factor was NPK fertilizer rate consisting of two levels (200 kg ha-1 Urea, 100 kg ha-1 SP-36, and 100 kg ha-1 KCl) from recommended fertilizer, and (102 kg ha-1 Urea, 0 kg ha-1 SP-36, and 66 kg ha-1 KCl) from the in situ soil analysis. The second factor was cow manure with four levels (2, 6, 8, and 10 Mg ha-1). The result showed that recommended NPK combined with 10 Mg ha-1 cow manure was the best for rice production in tidal lowland and produced 2.5 Mg ha-1. However, this result was not significant compared to NPK specific locations combined with the same rate of cow manure.

The purpose of this study was to evaluate the application of biocompost and mycorrhizae fungi on chemical properties of inceptisol soil and root infection on purple corn plants. This research was conducted in October-December 2020 at Experimental Garden, Faculty of Agriculture, Universitas Malikussaleh in Reuleut Village, Muara Batu District, Aceh Utara, employing Randomized Block Design (RBD) Factorial with 2 factors observed. The first factor observed was different doses of biocompost: B0 (0 ton/ha, 0 g/plot), B1 (5 tons/ha, 1500 g/plot), B2 (10 tons/ha, 3000 gr/plot) and B3 (15 tons/ha, 4500 gr/plot). The second factor was M0 (0 ton/ha, 0 gr/plot, 0 g/plant), M1 (0.25 tons/ha, 75 g/plot, 5 g/plant) dan M2 (0,5 ton/ha, 150 g/plot, 10 g/plant). The results indicated that the application of biocompost together with mycorrhizae has increased soil pH from 5.0 to 5.5 and the application of biocompost alone has improved the organic C (1.58% to 2.98%) and the application of mycorrhizae improved the root infection by 90%. The application of 5 ton/ha biocompost and 0.5 ton/ha mycorrhizae were to be found to be the best doses to improve the chemical properties of inceptisol soil and mycorrhizal infection.Keywords: biocompost, inceptisols, purple corn, mycorrhizal fungi

Sustainable forage production is needed to meet animal feed needs as the livestock industry increases. The purpose of this study is to evaluate the effect of liquid and solid carrier material on the effectiveness and infectivity of Bradyrhizobium sp. strain PZS_A08 on the growth of Indigofera zollingeriana (I. zollingeriana). The two carrier materials used were zeolite (solid) and molasses (liquid). This study used two carrier materials consisting of zeolite (solid) and molasses (liquid). The five treatments given were P0 (50% NPK), P1 (50% NPK+liquid biofertilizer), P2 (50% NPK+sterile liquid biofertilizer), P3 (50% NPK+solid biofertilizer), P4 (50 % NPK+sterile solid biofertilizer), P5 (100% NPK). Observations were made on the plant's height, number of leaves, number of nodules, upperparts and root wet biomass, root and upper parts dry biomass, root length, and microbial population). The use of liquid and solid carrier materials effectively affected the effectiveness and infectivity of Bradyrhizobium sp. strain PZS_A08 on I. zollingeriana. Inoculants Bradyrhizobium sp. strain PZS_A08 significantly increased plants' growth and reduced the use of 50% NPK fertilizer. Cold storage temperature (5ºC) effectively maintained Bradyrhizobium sp. strain PZS_A08 on liquid and solid carriers, while solid carriers showed better effectiveness at room temperature storage (30oC). Through this research, solid carriers such as zeolite are recommended as carriers for Bradyrhizobium sp. filter PZS_A08.

Objectives: Familial Mediterranean Fever (FMF) is a self-limiting autoinflammatory disease. In order to better understand the prognosis of diseases, disease severity scores are used. The aim of this study is to determine the effect of genetic mutations on disease severity scores in children with FMF.
Methods: 303 patients between the ages of 0-18, who were diagnosed with FMF according to Yalçınkaya-Özen diagnostic criteria and whose gene analysis was studied, were evaluated retrospectively. Pras et al's scoring system, Mor et al's scoring system and International severity score of FMF (ISSF) scoring system were applied to all patients. Genotypes were compared according to disease severity scores.
Results: When the patients were divided into 4 groups as M694V homozygous, heterozygous, M694V/other allele combined heterozygous and other mutations, according to the score of Pras et al., the frequency of mild disease tended to be less in the M694V homozygous group. When the patients divided as homozygous M694V, heterozygous M694V, heterozygous E148Q, heterozygous M694V/M680I combined mutations, according to the score of Pras et al., mild disease was found to be less common in the homozygous M694V group. When patients were divided into homozygous and heterozygous M694V groups, the disease was more severe in the homozygous M694V group according to the three scoring systems.
Conclusions: Based on the scoring system described by Pras et al., the rate of severe disease was higher in patients with homozygous M694V allele, whereas the rate of mild disease was statistically significantly higher in the heterozygous group compared with homozygous group.

Published: March 2022

Aim: This study aimed to evaluate the effectiveness of ultrasound-guided transversus abdominis plane (TAP) block in patients diagnosed with chronic pain after undergoing lower abdominal surgery.
Methods: Patients who were admitted to the pain medicine clinic between January 1, 2016, and January 1, 2020, and underwent TAP block with the diagnosis of chronic pain after undergoing lower abdominal surgery were retrospectively analyzed. The visual analog scale (VAS) score was measured before the procedure and at the 1-month and 3-month follow-ups.
Results: The proportion of patients with a reduction in VAS scores of >50% after TAP block application was 50% at the 1-month follow-up and 72.5% at the 3-month follow-up. The changes in the VAS score was found to be statistically significant (p < 0.05).
Conclusion: Although ultrasound-guided TAP block seems to be an effective treatment method for chronic pain after lower abdominal surgery, further studies and clinical trials investigating different types of surgeries and including a larger number of patients are warranted.

Pediatric Basic Life Support is the initiation of cardiopulmonary resuscitation (CPR) until advanced life support is available. The American Heart Association (AHA) 2015 guideline recommend the people to perform CPR.
YouTube is a video sharing site where internet users can learn about many topics, including health. Everyone can upload videos easily. Therefore, there is no control mechanism for the accuracy and up-to-dateness of the videos. Thus, there is a risk of spreading incorrect or inaccurate information.
After the pediatric CPR and BLS guidelines were updated in 2015, we aimed to evaluate the quality and content of the videos published in English on YouTube.
The YouTube website was searched in 15th June, 2020, using the terms “pediatric cardiac massage” and “pediatric BLS”. A total of 200 videos were evaluated.by two anesthetists in terms of instructional, content, up-to dateness and resource.
33 videos included in the study were evaluated according to Azer SA criteria. 14 videos were found to be useful and 19 of them as misleading. The average total viewing times and daily viewing numbers of useful videos were found to be higher. When evaluated in terms of content, similar results were obtained in both groups. This shows that viewers value videos more being educational than content. For this reason, we think that while editing videos, Azer criteria should be taken into account as an objective criterion and their content should be prepared according to current guidelines.

Published: March 2022

Introduction:
Many studies track outcomes after procedures, such as posterior lumbar fusion (PLF), for only 30 days because of database limitations. However, adverse events may not have plateaued by this time. Thus, this study used an alternate database to evaluate the timing of adverse events for 90 days after PLF.

Methods:
Adult PLF patients were identified from the 2010 to 2020 Q2 M53Ortho PearlDiver administrative data set. Ninety-day rates of multiple adverse events were determined. The time of diagnosis for each event in the 90-day postoperative period was determined. Data were dichotomized by occurrence in days 0 to 30 and 31 to 90. Median, interquartile range, and middle 80% for the time of diagnosis were determined for each adverse event.

Results:
Of 51,915 patients undergoing PLF, 7,141 (13.8%) had an adverse event within 90 days of PLF. Of these, 5,174 (72.5%) experienced an event within 30 days and 2,544 (35.6%) after 30 days. For individual adverse outcomes studied, the percent that occurred 31 to 90 days after surgery ranged from 9% to 42%. The time of diagnosis (median; interquartile range; middle 80%) for each adverse event was as follows: transfusion (2 days; 2 to 5 days; 1 to 26 days), acute kidney injury (9; 2 to 29; 1 to 60), hematoma (9; 4 to 20; 3 to 39), cardiac event (11; 3 to 43; 1 to 71), pneumonia (12; 4 to 38; 2 to 68), venous thromboembolism (15; 6 to 33; 3 to 62), sepsis (19; 9 to 39; 4 to 63), surgical site infection (21; 14 to 34; 8 to 48), urinary tract infection (22; 8 to 49; 4 to 72), and wound dehiscence (27; 17 to 39; 9 to 54).

Discussion:
This study highlights the importance of looking past the 30-day mark for adverse events after PLF because approximately one-third of adverse events in this study were diagnosed 31 to 90 days after surgery. This can affect research studies, patient counseling about the incidence of specific adverse events, and the development of mechanisms for surveillance at key time points.

Issue yang berkembang dalam pemberlakuan tariff angkutan wisata di sungai musi belum menggali aspek social ekonomi maupun financial harga(tariff) angkutan yang di gunakan atau diberlakukan pada saat ini. Pada penelitian ini dilakukan analisis dengan melakukan survai dan kajian perhitungan tariff yang ber indicator pada harga dalam rupiah perkilometer( KM 73 Tahun 2004), namun dilain pihak dilakukan juga kajian bagaimana share tariff yang diinginkan penumpang/wisatawan serta operator kapalnya sendiri.
Dan sesungguhnya antara share harga yang ditawarkan operator bila dibandingkan dengan kemampuan membayar dan keinginan membayar penumpang (Willingness to pay and ablity to pay) bahwa nilai deviasi harga keduanya hamper tidak jauh berbeda atau sekitar 2,5-3,0 persen.
Tetapi bila dibandingkan dengan hasil perhitungan yang berdasarkan tariff jarak(KM 73/2004), bahwa getek harganya Rp 192.600/kapal/trip dan speedboat Rp 179.760/kapal/trip. Harga ini lebih rendah sekitar 50 persen dari harga yang ditawarkan operator maupun keinginan dan kemampuan membayar penumpang wisata. Mengingat tingkat kesenjangan perhitungan yang cukup tinggi, maka perlu dikaji lagi ketentuan khusus untuk tariff kapal wisata.
