Chalcophile Element Heterogeneity in Ni-Cu-(Platinum Group Element) Orebodies of Raglan Horizon in Cape Smith Belt: Implications for Ore-Forming Processes
Authors: Li Ying Zhou , Mungall James E. 
Published: March 2022

Abstract
The komatiitic Raglan Horizon in northern Quebec hosts one of the largest komatiite-associated magmatic sulfide deposits in the world. Several studies have suggested that the sulfide ores were formed by melting and transporting sedimentary sulfides from upstream after the komatiite melt had assimilated a large amount of S-rich country rocks. In this study, we report new compositional data of the sulfide ores in Zones 5-8 and 13-14 along with the legacy assay database to investigate variability of the ore-forming processes at Raglan at the camp scale. More than 90,000 drill core samples were selected, and the rocks are categorized into disseminated, net-textured, and massive sulfide based on their sulfide abundance. We demonstrate that the majority of the compositional variability of the sulfide-bearing rocks can be attributed to the difference in the mass ratio between silicate and sulfide melts (R factor), by applying thermodynamic modeling of silicate and sulfide magma evolution. The massive sulfides display depletions in Cu, Pd, and Pt that are best explained by sulfide liquid fractionation, which differentiates the residual Cu-, Pd-, and Pt-rich sulfide liquid from the Ni-rich monosulfide solid solution (MSS) cumulate now preserved within the massive sulfide ores. A small population of sulfide-bearing samples that is strongly depleted in all the economically important metals has been interpreted to represent externally derived xenomelts that were poorly equilibrated with the metal-rich host magma due to low residence time. A portion of massive sulfides has been found to be depleted in Pd and Cu but not Pt. This decoupling of these metals can be well explained by a postmagmatic process that persisted to temperatures as low as 300°–350°C. Similar depletions of Pd have also been observed in the Expo Intrusive Suite immediately to the south. The regional variations in the compositions of individual orebodies suggest that they occurred in highly localized environments that record only local magmatic conditions and that the sulfide mineralization did not reach equilibrium with a single regionally continuous silicate magma system. Each zone preserves a unique signature of assimilation, sulfide segregation, and sulfide crystallization; hence, they likely represent separate magmatic pulses within the larger Raglan system. Lastly, based on the spatial locations of the low tenor sulfides, we tentatively suggest that Zone 2 and the Katinniq zone are more proximal to the as-yet-unidentified eruption site of the Raglan komatiite lava flow field.

Rangarajan (1952) studied fogs that occurred at Santacruz airport during the period 1942 to 1951. In the present study cases of low visibility at Santacruz airport due to thick mist or fog during the period January 1952 to April 1959 have been examined taking into account conditions at the surface as well as in the upper air. An unusual case of fog which occurred on 16 October 1960 has also been examined.
Mean Meridional air-motion and associated transport process in the atmosphere
Authors: RAO M. S. V. 
Published: March 2022

Eliassen's equation of quasi-static balance has been rederived in a more suitable frame of co-oridinates and, by making certain simplyfying assumptions, rendered into a form which lends itself easily to solution by relaxation. The differential equation thus obtained is solved for extended sources of heat and momentum similar to those actually encountered in the troposphere. The results show a mean meridional circulation consisting of a strong direct cell in low latitudes and a week indirect cell in the middle latitudes.
In section 3 of the paper, starting from the idea that the mean meridional circulation is split up into cells and making use of the values of the strength of the circulation deduced by Tucker and Mintz, the sources and sinks of heat and momentum necessary to maintain such mean motion are evaluated. Further, an attempt is made to infer what the character of eddy motion in the meridional plane has to be in order to satisfy balance requirements.

Published: March 2022

Introduction:
Cephalomedullary nail (CMN) length for intertrochanteric femur fractures without subtrochanteric extension has been an ongoing debate. The authors hypothesize that increasing nail length would result in increasing surgical time, greater incidence of acute kidney injury (AKI), postoperative anemia, and blood loss requiring transfusion due to increased intramedullary reaming and pressurization of the canal with nail insertion.

Methods:
A retrospective chart review of patients aged 65 years or older who underwent CMN for low-energy intertrochanteric femur fractures from 2010 to 2018 was undertaken. Patient demographic data, comorbidities, case duration, postoperative hospital length of stay (LOS), and laboratory data, including serum creatinine, hemoglobin, and hematocrit, were collected for analysis. The following outcome measures were compared: postoperative pneumonia, cardiac complications, sepsis, reintubation/intensive care unit stay, pulmonary embolism, stroke, postoperative AKI, 30-day hospital readmission, 30-day return to operating room, 30-day mortality, 1-year mortality, postoperative anemia (hemoglobin <7 g/dL), and blood transfusion.

Results:
A total of 247 patients were analyzed (short = 48, intermediate = 39, and long = 160). No notable difference was observed in postoperative pneumonia, cardiac complications, sepsis, reintubation/intensive care unit stay, pulmonary embolism, stroke, mean total hospital LOS, mean postoperative hospital LOS, rate of postoperative AKI, 30-day readmission, 30-day return to operating room, 30-day mortality, or 1-year mortality. Patients receiving long nails had significantly higher rates of postoperative anemia (P = 0.0491), blood transfusion (P = 0.0126), and mean procedure length (P = 0.0044) compared with the two other groups.

Discussion:
Patients receiving long nails had markedly higher rates of postoperative anemia and blood loss requiring blood transfusion with markedly longer mean procedure length than patients receiving short and intermediate CMNs. Long nails did not result in an increase in other complications evaluated.

Published: March 2022

Introduction:
The toy industry has grown substantially over time, with billions of dollars of toys sold each year in the United States alone. Even after safety considerations, injuries can result. This study examined toy-related fractures in the US Emergency Departments (ED).

Methods:
The 1999 to 2018 National Electronic Injury Surveillance System from the US Consumer Product Safety Commission was examined data for fractures involving a toy-related injury. The incidence, trends, and anatomic locations for such fractures were assessed.

Results:
In total, 347,135 toy-related fractures were identified, of which 237,754 (68%) were in patients younger than 18 years, 182,516 (53%) were sustained by male subjects, and a 95% yearly incidence increase was observed over the years of the study. Anatomically, 37% were shoulder/arm/elbow, 24% wrist/hand/finger, 19% ankle/toe/foot, 10% leg/knee, 6% face/neck/head, and 4% trunk/pubic region.

Discussion:
Despite safety considerations with toy design, more than a third of toy-related fractures were seen in the ED, with a nearly doubling yearly incidence over the study period. This could be contributed to by increased production and prevalence of toys and/or rougher play and increased overall violence. These results are important not only for patient safety but also for orthopaedic surgeons, EDs, toy manufacturers, and policymakers.

Published: March 2022

ZTP (Zero Touch Provisioning) adalah sebuah inovasi dalam dunia IT, yang merubah cara melakukan konfigurasi perangkat yang sebelumnya manual menjadi otomatis. Inovasi ini tercipta dikarenakan semakin banyaknya kebutuhan akan perangkat jaringan. Tantangan tersendiri bagi perusahaan jaringan untuk mengelolanya baik dari sisi waktu dan biaya. Pada metode tradisional, Administrasi perangkat jaringan harus masuk ke setiap perangkat jaringan satu persatu untuk melakukan konfigurasi. Hal tersebut tentunya tidak efisien. Disinilah kelebihan dari otomasi, konfigurasi perangkat jaringan menjadi lebih efisiensi, ditambah pekerjaan yang sifatnya repetitive seperti backup konfigurasi, monitoring, bisa dilakukan dengan otomatis. Pada penelitian ini penulis akan menguji sebara efisien penggunaan dari ZTP dengan cara membandingkan waktu konfigurasi dengan cara manual dan otomasi dengan ztp. Konfigurasi yang akan di lakukan pada penelitian ini adalah konfigurasi IP Address, membuat DHCP server, dan membuat hotspot pada MikroTik. Untuk memudahkan melakukan manajemen jaringan penulis membuat dashboard untuk mengetahui perangkat mana yang sudah dikonfigurasi. Sistem otomasi sendiri dibuat dengan menggunakan pemrograman Python yang memanfaatkan library utama Paramiko sebagai penghubung antara perangkat jaringan dengan server otomasi melalui protokol SSHv2.

Published: March 2022

This study aimed to determine the effect of different solvents and temperatures on the citral concentration and antioxidant properties of freeze-dried lemongrass powder extract. Freeze-dried lemongrass powder was extracted using three solvent extractions of hexane, petroleum ether, and methanol at three different temperatures of 27°C, 40°C, and 60°C. Citral concentrations of lemongrass extract were identified and quantified by gas chromatography and flame ionization detector (GC-FID) while antioxidant properties were determined using analysis of total phenolic content, DPPH radical scavenging activity, and ferric reducing antioxidant power (FRAP) assay. Results from this study show that the methanol extract at 40°C obtained the highest total yield (37.70 ± 1.78%). Hexane was found to be the most effective solvent to extract citral compound from freeze-dried lemongrass powder with 239.08 ± 1.28 mg/mL of concentration at temperature extraction of 27°C. However, the efficiency of hexane decreasing upon heating. This study suggested that the solvent extraction using methanol at 40°C is the efficient extraction for total phenolic compound (7419.33 ± 110.78 mg GAE/L), DPPH radical scavenging activity (87.45
± 2.70%), and FRAP assay (52.11 ± 0.07 TE/mL) of freeze-dried lemongrass powder.

Published: March 2022

Sindrom Eisenmeger adalah kelainan jantung dengan karakteristik hipertensi pulmonal yang disertai pirau kanan ke kiri ataupun dua arah, akibat jangka panjang defek septum interventrikel atau patent ductus arteriosus (PDA) yang tidak diterapi. Kehamilan sulit ditoleransi pada pasien dengan sindrom Eisenmenger dimana mortalitas ibu mencapai 30-50%. Perubahan fisiologis menurunkan tahanan vaskular sistemik yang memperburuk pirau. Seksio Sesarea merupakan pilihan teknik persalinan pada kondisi tersebut. Kami melaporkan dua pasien dengan sindrom Eisenmenger yang berhasil menjalani seksio sesarea dengan anestesi umum. Anestesi umum dilakukan dengan teknik titrasi dan menggunakan obat dengan pengaruh minimal terhadap sistem kardiovaskular. Selama operasi pasien diberikan milrinon yang dikombinasikan dengan agen katekolamin. Pascaoperasi pasien dirawat di ICU. Selama perawatan di ICU tidak ada komplikasi signifikan yang terjadi. Pasien pertama berhasil pindah ke ruang rawat pada hari ke-3 pascaoperasi, sedangkan pasien ke-2 pindah pada hari ke-7 pascaoperasi. Tujuan manajemen anestesi pada pasien sindrom Eisenmenger adalah mempertahankan SVR, menjaga kecukupan volume intravaskular dan mencegah peningkatan lebih jauh PVR. Penggunaan milrinon yang dikombinasikan dengan agen katekolamin dapat membantu tercapainya tujuan tersebut sehingga dapat memperbaiki oksigenasi dan mempertahankan hemodinamik pasien. Walaupun kehamilan pada pasien Eisenmenger tidak dianjurkan, namun persalinan melalui seksio Sesarea masih dapat dilakukan dengan manajemen yang baik.
Comparison of C-MAC® Video Laryngoscope and Macintosh Conventional Laryngoscope for Nasotracheal Intubation Convenience in Adult Malay Race Population
Authors: Heriwardito Aldy , Rahendra  , Wicaksono Ananto Wiji 
Published: March 2022

Background: Nasotracheal intubation is a widely used airway management method, especially in oral surgeries. Various devices were found to perform intubation techniques, such as video laryngoscopes. C-MAC® video laryngoscope enables better glottis visualization compared to the Machintosh conventional laryngoscope. C-MAC® demonstrates higher success rates of orotracheal intubation especially in difficult airway cases. However, this device has not been commonly used in nasotracheal intubation yet.
Methods: A single blinded randomized clinical trial study of 86 subjects were done to compare the use of C-MAC® video laryngoscope and Macintosh conventional laryngoscope with reference to their success rates of intubation and duration of nasotracheal intubation in adult Malay patients. Patients with difficult airway, pregnancy, acute ischemic heart disease, heart failure, second- or third-degree block, uncontrolled hypertension, Guillen Barre syndrome, Myasthenia Gravis, and contraindications to nasotracheal intubation were excluded.
Results: C-MAC® demonstrated a higher success rate at first attempt of intubation (RR 1,265, 95% CI (1,084-1,475)) and required a shorter duration of intubation (p value <0.001) compared to the Macintosh conventional laryngoscopes in adult Malay.
Conclusion: In adult Malay patients, nasotracheal intubation is better performed with the C-MAC® video laryngoscope compared to the Macintosh conventional laryngoscope. High rate of successful first attempt and shorter duration of the process indicate more convenient and easier intubation.
