Published: June 2021

Penyaluran tenaga listrik baik dari Pembangkit sampai ke Gardu induk sampai ke konsumen harus diperhatikan keandalan dan efisiensinya, agar tenaga listrik yang tersalurkan berkualitas dan memiliki kontinuitas yang baik. Guna menjaga kualitas tenaga listrik agar tetap andal dan efisien serta agar kontinuitas penyaluran tenaga listrik tetap terjaga dengan baik, beberapa komponen peralatan penyaluran tenaga listrik harus menjadi perhatian untuk mencegah terjadinya gangguan terhadap peralatan tenaga listrik. Salah satu gangguan pada peralatan tenaga listrik adalah titik panas (hot point). Seringnya terjadi gangguan tersebut pada titik pertemuan antara klem dan konduktor pada peralatan listrik menjadi tolak ukur pemeliharaan dalam penyediaan tenaga listrik. Tindakan pencegahan agar tidak terjadinya hot point disebut thermovisi, dengan menggunakan alat ukur thermal imagers. Prinsip kerja thermal imagersadalah merefleksikan cahaya infrared terhadap peralatan kemudian menangkap suhu peralatan tersebut dan menampilkannya pada sebuah display. Kegiatan thermovisi dilakukan secara rutin sebagai kegiatan monitoring pemeliharaan tenaga listrik yang kemudian dilakukan analisa hasil thermovisi tersebut dengan melakukan perhitungan emisivitas melalui pendekatan selisih suhu klem dan konduktor (∆T) agar didapatkan nilai emisivitas yang sesuai.Selanjutnya dilakukan uji validasi untuk menguji keakuratan dan presisi dari hasil thermovisi tersebut.Penelitian yang dilakukan di GI 150 kV Glugur bertujuan untuk merekomendasikan hasil uji analisa matematis terhadap tindak lanjut kondisi peralatan. Hasil dari kondisi peralatan pada analisa 30 sampel menunjukan bahwa peralatan masih dalam kondisi baik dan masih layak digunakan, dengan nilai akurasi sebesar 98,02% dan presisi sebesar 0,25% pada peralatan bay penghantar Glugur - Paya Geli 1 serta nilai akurasi pada bay penghantar Glugur – Paya Geli 2 sebesar 97,9% dan 0,24% pada nilai presisinya.

OBJECTIVE
Cortical screw–rod (CSR) fixation has emerged as an alternative to the traditional pedicle screw–rod (PSR) fixation for posterior lumbar fixation. Previous studies have concluded that CSR provides the same stability in cadaveric specimens as PSR and is comparable in clinical outcomes. However, recent clinical studies reported a lower incidence of radiographic and symptomatic adjacent-segment degeneration with CSR. No biomechanical study to date has focused on how the adjacent-segment mobility of these two constructs compares. This study aimed to investigate adjacent-segment mobility of CSR and PSR fixation, with and without interbody support (lateral lumbar interbody fusion [LLIF] or transforaminal lumbar interbody fusion [TLIF]).

METHODS
A retroactive analysis was done using normalized range of motion (ROM) data at levels adjacent to single-level (L3–4) bilateral screw–rod fixation using pedicle or cortical screws, with and without LLIF or TLIF. Intact and instrumented specimens (n = 28, all L2–5) were tested using pure moment loads (7.5 Nm) in flexion, extension, lateral bending, and axial rotation. Adjacent-segment ROM data were normalized to intact ROM data. Statistical comparisons of adjacent-segment normalized ROM between two of the groups (PSR followed by PSR+TLIF [n = 7] and CSR followed by CSR+TLIF [n = 7]) were performed using 2-way ANOVA with replication. Statistical comparisons among four of the groups (PSR+TLIF [n = 7], PSR+LLIF [n = 7], CSR+TLIF [n = 7], and CSR+LLIF [n = 7]) were made using 2-way ANOVA without replication. Statistical significance was set at p < 0.05.

RESULTS
Proximal adjacent-segment normalized ROM was significantly larger with PSR than CSR during flexion-extension regardless of TLIF (p = 0.02), or with either TLIF or LLIF (p = 0.04). During lateral bending with TLIF, the distal adjacent-segment normalized ROM was significantly larger with PSR than CSR (p < 0.001). Moreover, regardless of the types of screw-rod fixations (CSR or PSR), TLIF had a significantly larger normalized ROM than LLIF in all directions at both proximal and distal adjacent segments (p ≤ 0.04).

CONCLUSIONS
The use of PSR versus CSR during single-level lumbar fusion can significantly affect mobility at the adjacent segment, regardless of the presence of TLIF or with either TLIF or LLIF. Moreover, the type of interbody support also had a significant effect on adjacent-segment mobility.

OBJECTIVE
Adjacent-segment disease (ASD) requiring operative intervention is a relatively common long-term consequence of lumbar fusion surgery. Although the incidence of ASD requiring reoperation is well described for traditional posterior lumbar approaches (2.5%–3.9% per year), it remains poorly characterized for stand-alone lateral lumbar interbody fusion (LLIF). In this study, the authors report their institutional experience with ASD requiring reoperation after LLIF over an extended follow-up period of 4 years.

METHODS
Medical records were reviewed for 276 consecutive patients who underwent stand-alone LLIF by a single surgeon for degenerative spinal disorders. Inclusion criteria (single-stage, stand-alone LLIF without posterior supplementation, with no prior lumbar instrumentation, and a minimum of 4 years of follow-up) were met by 182 patients, who were analyzed for operative ASD incidence (per-year rate), demographics, and Oswestry Disability Index (ODI) score. Operative ASD was strictly defined as new-onset pathology following index surgery at directly adjacent levels to the prior construct. Operative, rather than symptomatic or radiographic, ASD was analyzed to provide a consistent and impactful endpoint while avoiding retrospective diagnosis.

RESULTS
The study cohort of 182 patients had an operative ASD rate of 3.3% (n = 6 procedures) over 4 years of follow-up, for an incidence on Kaplan-Meier survival analysis of 0.88% (95% CI 0.67%–1.09%) per year. In comparing patients with operative ASD with those without, there were no significant differences in mean age (53.7 vs 56.2 years), male sex (33.3% vs 44.9%), smoking status (16.7% vs 25.0%), or number of levels fused (mean 1.33 vs 1.46). The operative ASD cohort had a greater mean BMI (37.3 vs 30.2, p < 0.01). Operative ASD patients had lower baseline ODI scores (33.8 vs 48.3, p = 0.02); however, no difference was observed in ODI at 6 weeks (34.0 vs 39.0) or 3 months (16.0 vs 32.8) postoperatively.

CONCLUSIONS
The incidence of ASD in LLIF for degenerative lumbar etiologies in this cohort was 0.88% (95% CI 0.67%–1.09%) per year. Meanwhile, the reported reoperation rates for ASD in posterior spinal approaches was 2.5% to 3.9% per year, which implies that LLIF may be preferable for well-selected patients.
A Greek Source for the Treatise on the Composition of Man Attributed to Aḥūdemmeh Anṭīpaṭrōs?
Authors: Benfey Thomas 
Published: June 2021

Abstract
Here I establish the close relationship between a large portion of the Syriac Treatise on the Composition of Man attributed to Aḥūdemmeh Anṭīpaṭrōs, originally published by Chabot in 1943, and the Greek pseudo-Hippocratic treatise originally published as On the Formation of Man by Jouanna in 2006, arguing that one of these texts must be a translation of the other. While firm conclusions about the direction, place and time of this translation must await an improved edition of the Syriac text, I make several suggestions on these points as well. I also show that the Greek pseudo-Hippocratic text may need to be revised, since certain manuscripts consistently agree with the Syriac against others.
From Tigris to Jerusalem: East Syriac Poetic Notes from the Ottoman Time
Authors: Pritula Anton 
Published: June 2021

Abstract
The poems published and studied here - most of them for the first time - represent literary tastes of East Syriac educated circles of the Ottoman period. These text collections appeared as later additions in the manuscripts written by ʿAbdīšōʿ of Gāzartā, the Uniate East Syriac Church poet and the second patriarch (1555-1570). These small texts, usually having very little or even nothing to do with the main manuscript text, represent a kind of verse notes made by different pilgrims, and reflect popular poetic tastes of the period. Short poems, especially quatrains, are an ideal form for such poetic activities. Judging from their great number, the spread of short poems was constantly increasing since the time the Syriac Renaissance, when they were first borrowed from Arabic and Persian poetry. Apparently, the multi-lingual poems of the Mongol period (second half of the 13th-early 14thcentury) - the heyday of the Syriac tradition in the Islamic period - were treated as appropriate models to portray contemporary cultural life of the multi-lingual Christian communities in the Ottoman Empire.

Published: June 2021

BACKGROUND: Strawberry fruits are perishable with a short post-harvest life. Cinnamyl alcohol dehydrogenase (CAD) is the key enzyme for lignin biosynthesis strengthening plant cell wall. A systematic characterization of strawberry CAD family is absent and their involvement in fruit firmness is largely elusive. OBJECTIVE: Current work aims for a genome-wide identificationof CAD family and its expression correlation with fruit firmness in strawberry varieties. METHODS: A genome-scale identification and molecular characterization for CADs were performed in the commercial strawberry ( Fragaria× ananassa) and woodland strawberry ( F. vesca). qPCR analysis of CAD homoeologs in three cultivars varying with fruit firmness revealed candidate CAD members positively correlated with lignin content and fruit firmness. RESULTS: A total of 14 and 24 CAD loci were identified in the genomes of F. vesca var. Hawaii4 and F. × ananassa cv. Camarosa, respectively.Phylogenetic analysis supported a division of this family into three classes. Class I FvCAD each has four homoeologs in commercial strawberry, while those of Class II and Class III have only one or two homoeologs. Except for FvCAD2 and -6, there exits at least one pair of CADs sharing ∼97% or above amino acid identity between F. vesca and F. × ananassa.The flesh firmness and lignin content varied greatly among strawberry germplasm. Distinct dynamic changes in fruit lignin content were observed before the large green stage, but fruit firmness displayed a similar decrease profile during fruit development in three varieties. Of the eight genes detected in F.× ananassa, FvCAD3 and -12 did not display a F. vesca-biased expression pattern during fruit development. FvCAD4 of Class I was expressed at levels positively correlated with variation in fruit lignin content at white stage.Transcript abundance of five Class IIgenes including FvCAD3, - 8, - 10, - 11, and - 12 was positively correlated with lignin content and fruit firmness, with FvCAD10 and - 11 ( FaCAD in previous publication) reaching an extremely significant correlation with the genetic variation in fruit firmness across three varieties. CONCLUSION: Strawberry Class II CADs were significantly correlated with the genetic variation in fruit firmness, which might expand the potential choices for improving strawberry shelf life.

Published: June 2021

BACKGROUND: One key factor proven to increase quality of pregnancy outcome has been antenatal care (ANC) service. The perinatal triad of mother, placenta and fetus becomes functionally complete with a functional umbilical cord. The objective of the study was to establish mathematical models to predict the outcome of umbilical cord morphometric parameters using maternal first antenatal care visit biometric indices. METHOD: This analytical descriptive cross-sectional study was conducted on 240 pregnant women who attended antenatal care for the first time in their first trimester at the Victory Maternity Home and Clinic in the Kumasi Metropolis, between April 2016 and October 2019. Umbilical cord length, diameter, area, volume and weight were measured after delivery. Maternal first antenatal care visit blood pressure was taken and their non-fasting blood samples were collected and lipid profile done. RESULTS: Mean values for umbilical cord measurements were; cord length, 38.10±7.86 cm; diameter, 1.04±0.17 cm; area, 66.10±24.49 cm2 and volume was 34.02±11.16 cm3 respectively while mean cord weight was 65.01±21.35 g. The study found that a unit increase in total cholesterol led to an increase of 2.33 units in umbilical cord length, high-density lipoprotein also resulted in 0.06 units increase in cord diameter while low-density lipoprotein decreases cord length by 3.31 units. Also, a unit increase in maternal booking total cholesterol resulted in 2.33 units increase in umbilical cord length. CONCLUSION: Maternal first antenatal care visit total cholesterol, high-density lipoprotein and low-density lipoprotein could influence the outcome of umbilical cord length, diameter and area.

BACKGROUND: Impaired upper extremity function due to muscle paresis or paralysis has a major impact on independent living and quality of life (QoL). Assistive technology (AT) for upper extremity function (i.e. dynamic arm supports and robotic arms) can increase a client’s independence. Previous studies revealed that clients often use AT not to their full potential, due to suboptimal provision of these devices in usual care. OBJECTIVE: To optimize the process of providing AT for impaired upper extremity function and to evaluate its (cost-) effectiveness compared with care as usual. METHODS: Development of a protocol to guide the AT provision process in an optimized way according to generic Dutch guidelines; a quasi-experimental study with non-randomized, consecutive inclusion of a control group ([Formula: see text] 48) receiving care as usual and of an intervention group (optimized provision process) ([Formula: see text] 48); and a cost-effectiveness and cost-utility analysis from societal perspective will be performed. The primary outcome is clients’ satisfaction with the AT and related services, measured with the Quebec User Evaluation of Satisfaction with AT (Dutch version; D-QUEST). Secondary outcomes comprise complaints of the upper extremity, restrictions in activities, QoL, medical consumption and societal cost. Measurements are taken at baseline and at 3, 6 and 9 months follow-up.
АНАЛІЗ НАДІЙНОСТІ ШАСІ РЕГІОНАЛЬНОГО ПАСАЖИРСЬКОГО ЛІТАКА АН-140 НА ПОЧАТКОВОМУ ЕТАПІ ЕКСПЛУАТАЦІЇ

The article presents an analysis of the reliability of the chassis of the regional passenger aircraft AN - 140 at the initial stage of operation, as well as general information about the aircraft, front and main supports of its landing gear. The average failure rate and the total number of failures over a period of time are used as reliability indicators. The calculation of reliability indicators is based on failures detected during periodic maintenance (PM) of aircraft on planned forms 1H - 4H in the maintenance organization Part - 145 and entered into defective statements in accordance with the Management Maintenance Organization. These forms are made in accordance with the Aircraft Maintenance Manual of AN - 140 with a frequency of 500±50 flight hours. To analyze the reliability of the chassis selected a fleet of six aircraft AN - 140 and AN - 140 - 100 with a total flight of 12,000 hours and is divided into three groups by the date of their manufacture and the improvements made on them - "Leader Planes," "Refined Aircraft" and "Serial Aircraft". The condition of sampling the fleet of aircraft is the flight time of 2000 hours for each instance and the execution of four forms of PM on a swoop to form 4N. The dependence of the number of failures of the landing gear of each aircraft on the shape of the PM, the average flight of failure of the fleet and each aircraft individually, the total number of failures of the landing system for each instance of the aircraft, the most denied elements of the main and front landing gear of the aircraft are presented.Based on the results of the analysis of these reliability indicators, both generalized conclusions on the distribution of the number of failures by groups and aircraft instances, and on the specific most denied elements of the chassis system as a whole are presented. The tendency to reduce the number of failures and increase the average flight to failure, depending on the duration of aircraft operation and the manufacture date, has been revealed.
