An Innovative Solution for Type Testing of Power Transformers
Authors: Singh Manohar , Telukanta Vishnuvarddhan , Meera K S
Published: February 2019

Type tests are essential to assess the short circuit withstand capabilities of transformer windings. The mechanical durability of power equipment are checked against the mechanical forces developed during making/breaking short circuit operations. These type tests are generally carried out in indoor transformer test laboratories. Testing of Power Transformer for size more than 200 MVA in 765/400 kV voltage class in an indoor laboratory is not economically feasible. Now a days, power transformer manufacturers are fabricating single phase auto- power transformers of size up to 630 megawatt volt ampere (MVA) rating. Type testing of these transformers in indoor laboratories is not feasible. In view of this, strong short circuit fault feeding capabilities of the national grids can be utilized for type testing of these power transformers in an online manner. However, this may affect the grid operation/control during weak grid operating conditions. Recently, National High Power Testing Laboratory is established for testing of power transformer upto of 630 MVA. This is a unique online transformer test facility for testing of 765/400/220/132 kV class power transformers. An offline simulation has been carried out in this article, to assess the impact of online type testing on the Indian National grid. In this article, an online testing scheme has been presented which enables the national grid operator to analysis the prevailing grid condition & subsequently to decide the safe rating of the power transformer for online testing. The simulated results are cross checked with field results and it is found that simulated results are close to actual field results. The concurrence of simulated and field results helped in successfully commissioning of the testing laboratory.
Temperature Effects on Thermodynamic Parameters and Solubility of Curcumin O/W Nanodispersions Using Different Thermodynamic Models
Authors: Sayyar Zahra , Jafarizadeh-Malmiri Hoda
Published: February 2019

Solubility of curcumin at different temperatures is of great importance in subcritical water extraction systems. We newly developed an approach for the solid–liquid equilibrium under subcritical condition to determine the solubility of curcumin. The experimental results were correlated successfully with thermodynamics models such as Van’t Hoff, modified Apelblat equation, Wilson, non-random two-liquid (NRTL) and λh equation and the interaction parameters’ values of curcumin-water were acquired. Good agreement between the experimental and calculated values with λh equation was observed at different temperatures (373.15–433.15 °K) at 1.5 bar. The obtained value of the relative average deviation was 2.29 × 10–5. The molar enthalpy (ΔH
0), entropy (ΔS
0), Gibbs energy (ΔG
0) and their relative fraction of the total process were calculated. The calculated enthalpy with the Van’t Hoff equation (25.32 kJ/mol) agreed well with the differential scanning calorimetry analysis data (26.15 kJ/mol).
The language of an inanimate narrator

Published: February 2019

We show by means of a corpus study that the language used by the inanimate first person narrator in the novel Specht en zoon deviates from what we would expect on the basis of the fact that the narrator is inanimate, but at the same time also differs from the language of a human narrator in the novel De wijde blik on several linguistic dimensions. Whereas the human narrator is associated strongly with action verbs, preferring the Agent role, the inanimate narrator is much more limited to the Experiencer role, predominantly associated with cognition and sensory verbs. Our results show that animacy as a linguistic concept may be refined by taking into account the myriad ways in which an entity’s conceptual animacy may be expressed: we accept the conceptual animacy of the inanimate narrator despite its inability to act on its environment, showing this need not be a requirement for animacy.
Extraordinary Bulging Mass in the Foetus - A Case Report of Bladder Exstrophy
Authors: Łosińska Joanna , Respondek-Liberska Maria
Published: February 2019

INTRODUCTION: Prenatal diagnosis of bladder exstrophy is extremley rare and difficult. BACKGROUND: Due to abnormal development of the cloacal membrane there is an incomplete closure of the lower abdominal wall, absence of the anterior wall of the bladder and external exposition of the posterior wall. The pubic bones are usually separated, the umbilical cord low inserted and there is abnormal external genitalia development. CASE REPORT: At 21st week of gestation of 39-year-old multigravida multipara referred by a primary care obstetrician to high-specialised centre for a detailed ultrasound examination with a suspicion of bladder absence and inferior umbilical localisation. At 29 weeks of gestation presence of bulging mass of 2 cm, between the umbilical outlet and labia was detected. At 31 weeks of gestation previously detected structure among thighs had 3 cm diameter with lateral umbilical outlet. Major labia were prominent and minor labia were within normal limits. Between two umbilical arteries with an appropriate intraabdominal course there were no transsonic area corresponding to the urinary bladder. The newborn baby was born at term in a good condition, but with an exposed bladder of 4 cm in diameter. The urethral outlet was not visualised and the female genitals were abnormal. After a month the girl underwent primary bladder exstrophy closure. Although she suffers from recurring urinary tract infections, she is in a good general condition. CONCLUSIONS: Due to prenatal diagnostics it was possible to detect and make an initial diagnosis of severe malformation. Early diagnosis allowed to prepare parents for a newborn with a defect and teach them how to take care of the baby.

Published: February 2019

Objective To investigate the predictive value of serum neopterin for multiple organ dysfunction syndrome (MODS) in severe burn patients. Methods Seventy-six severe burn patients with burns covering a total body surface area (TBSA) above 70% were included in this study. Of the 76 patients, 29 cases developed MODS (MODS group) and the remaining 47 subjects did not (non-MODS group). From the MODS group, 12 patients died (Death group) and 17 patients survived (Survive group). The serum level of neopterin in the MODS and non-MODS groups were examined by radioimmunoassay on following 1, 3 , 7 , 14 , 21 and 28 post-burn days (PBDs). A receiver operating characteristic (ROC) curve was used to analyse the predictive value of serum neopterin for MODS and death. Results The serum neopterin level in the MODS group was significantly higher than that of non-MODS group between 3~28 PBDs (p<0.001). However, the serum neopterin levels between the MODS and non-MODS groups following 1 PBD were not statistically significant (p>0.05). The best diagnostic performance of serum neopterin for MODS occurred 14 PBDs with the prediction sensitivity and specificity of 75.86% (56.46%~89.70%) and 85.11% (71.69%~93.80%) respectively. However, serum neopterin levels had no clinical value in predicting the death of MODS patients. The area under the ROC curve (AUC) was 0.72 (0.58~0.85), 0.81 (0.71~0.92) and 0.83 (0.72~0.94) for serum neopterin as biomarker in the prediction of MODS after 3, 7 and 14 PBDs, respectively. The AUCs were 0.50 (0.27~0.73), 0.53 (0.30~0.76) and 0.56 (0.33~0.79) for serum neopterin as biomarker in prediction of death for MODS patients after 3, 7 and 14 PBDs, respectively. Conclusion The persistent and significant increase of serum neopterin level is closely related to the development of MODS in patients with severe burns. Serum neopterin is therefore a promising serological marker for MODS early diagnosis, but has little efficacy in the prediction of the likelihood of death in severe burn patients with MODS.
Trimmed Whittle estimation of the SVAR vs. filtering low-frequency fluctuations: applications to technology shocks
Authors: Lovcha Yuliya , Perez-Laborda Alejandro
Published: February 2019

This paper shows that the trimmed Whittle estimation of the SVAR is superior to filtering (or differencing) undesired, low-frequency fluctuations that may arise in macroeconomic data. Pre-filtering destroys the low-frequency range of the spectrum, thus biasing the estimated parameters and the responses of the variables to shocks. The proposed method, by contrast, accounts for the undesired fluctuations while overcoming these drawbacks. Furthermore, the method remains reliable even when the observed low-frequency variability has been incorrectly considered as external to the SVAR. An empirical application that examines the effect of technology shocks on hours worked is provided to illustrate the results. We find the response of hours positive and similar using both long and short-run identification restrictions, thus providing a solution to a wide debate in the business cycle literature.

Published: February 2019

Road bicycles form an intrinsic part of economic transportation. The overall efficiency and performance depend solely on the weight and frame structure. The benchmarks for an innovative frame design are kept in terms of lightweight, fatigue failure, lateral stiffness, torsional stiffness, impact forces and loading capabilities. The deformation and propulsion of bicycle consume rider’s energy, a reduction in deformation and mass of the frame is therefore necessary. In the present work, the structural design and a quasi static vertical load analysis of the bicycle frame are presented using finite element analysis. Corrugated tubes are introduced into the main triangle with different sets of combination and the numerical result thus obtained was compared against the standard tubular bicycle frame.

Published: February 2019

We are in an era of MEMS and NEMS, to be precise a product with lean and an integral of ‘n’ number of electromechanical elements. For example, nearly 80% of components are electrical/electronics in an automobile unit. This leads to think on the future market, that would witness a paradigm shift from Mechanical centric systems to Mechatronics systems. An approach was implemented in this paper to see through how a measurement of physical parameter can be dealt with principles of Mechatronics. Measurement of heavy duty vehicles payload is a concern, as there exists a difficulty in identifying the location and capacity of weigh bridge units. To address this issue an experimental and simulation approach was adopted to quantify/correlate the results.
Performance of UWB-WBAN System Over Awgn Channel
Authors: Abdulhamid Mohanad F. , Ben Sewe Onyango
Published: February 2019

The major constraints in the design of Wireless Body Area Network(WBAN) can be attributed to the battery autonomy, need for high data rate services and low interference from the devices operating within the industrial, scientific and medical (ISM) bands. To meet the demand for high data rate services and low power spectral density to avoid ISM band interference, an ultra-wide band(UWB) system based technology has been proposed. This paper focuses on the design and demonstration of an UWB modem to be used in the WBAN applications and the evaluation of its performance in a near-real world scenarios affected by additive white Gaussian noise(AWGN) interference. The modem is tested with different values of signal to noise ratio(SNR). Results show that the performance of the modem degrades as the value of SNR decreases.

Authors: King Oluwatosin Damilola , Oke Sunday Ayoola
Published: February 2019

Quality improvement research in aircraft maintenance as well as our knowledge of the methods in the course of which enhancement is achieved and managed is disoriented and deficient. Current preventive maintenance practices are usually based on the number of flight cycles, flight hours or calendar time. Such PM activities are technical programme-oriented without any consideration for customer requirements are expectations. The unfortunate issue is that the results provided by these technically-oriented decisions are usually sub-optional. After characterised by poor customer satisfaction, requiring repeat services in some cases. A worse situation may even result such that total customer dissatisfaction may trigger out souring maintenance services despite having resources for repairs and services. In this communication, a complete departure from current practice in preventive maintenance of pure technical content to technical plus customer focused practice is adopted. This innovative approach involves obtaining customer requirements and translating them into design requirements in the house of quality of the quality function deployment (QFD). Questionnaire were developed and administered while the results were coupled with interviews to obtain the desired model validation of the QFD structure formulated. The results indicated feasibility of the proposed approach in practice. With thus novel contribution to literature, preventive maintenance managers in airline could confidently schedule services for success with a customer orientation.

Authors: AL-Rawi Muhanned , AL-Rawi Muaayed
Published: February 2019

Two detectors are presented in this paper which are used to handle intersymbol interference introduced by the communication channels. These two detectors are based on combination of nonlinear equalizer and Viterbi detector. The first detector, which was previously developed, is named Combined Detector1(CDR1), while, the second detector, which is the contribution of this paper, is named Combined Detector-2(CDR2). CDR2 is similar to CDR1 but with retraining data sequence. These detectors are tested beside nonlinear equalizer using data transmission at 9.6kb/s over telephone channel. Simulation results show that the performance of CDR2 is better than the performance of CDR1 while the performance of CDR1 is better than the performance of nonlinear equalizer.

Authors: Tas Ezel Ozge , Pala Elif , Ercan Ilker , Sag Sebnem
Published: February 2019

Objectives

Since studies regarding the effect of polysomy 17 (P17) in breast cancer cases with some specific clinical findings are few in number and are in small sample sizes, meta-analysis was implemented to exhibit the effects of P17 in patients with Human Epidermal growth factor Receptor 2 (HER2) amplification on lymph node involvement and tumor grade.

Materials and methods

Pubmed literature database was scanned up to June 2017 by using the keywords “polysomy 17 breast cancer” and 141 studies were accessed. Ultimately four of the reviewed papers have been found to be appropriate for examining the effect of P17 on lymph node involvement and tumor grade. Prior to meta-analysis, publication bias and heterogeneity of the studies was examined.

Results

Meta-analysis in the examining the effect of polysomy 17 on lymph node involvement (OR=1.708, 95% CI: 1.068–2.733), on grade [3]/[3,1] (OR=3.402, 95% CI: 1.726–6.707), on grade [3]/[3, 2] (OR=2.581, 95% CI: 0.778–8.559) and on grade [2]/[2,1] (OR=1.854, 95% CI: 0.531–6.468) was determined in those with HER2 amplification.

Conclusion

It was observed that in terms of lymph node involvement, P17 was a risk factor in patients and with regard to tumor grade, P17 was a risk factor when grade increased in patients with amplification.

Whitehead, S, Till, K, Weaving, D, Dalton-Barron, N, Ireton, M, and Jones, B. Duration-specific peak average running speeds of European Super League Academy rugby league match play. J Strength Cond Res 35(7): 1964–1971, 2021—This study aimed to quantify the duration-specific peak average running speeds of Academy-level rugby league match play, and compare between playing positions. Global positioning system data were collected from 149 players competing across 9 teams during 21 professional Academy (under-19) matches. Players were split into 6 positions: hookers (n = 40), fullbacks (n = 24), halves (n = 47), outside backs (n = 104), middles (n = 118), and backrow forwards (n = 104). Data were extracted and the 10-Hz raw velocity files exported to determine the peak average running speeds, via moving averages of speed (m·min−1), for 10- and 30-second, and 1- to 5- and 10-minute durations. The data were log transformed and analyzed using linear mixed-effect models followed by magnitude-based inferences, to determine differences between positions. Differences in the peak average running speeds are present between positions, indicating the need for position-specific prescription of velocity-based training. Fullbacks perform possibly to most likely greater average running speeds than all other positions, at each duration, except at 10 seconds vs. outside backs. Other differences are duration dependent. For 10 seconds, the average running speed is most likely greater for outside backs vs. the hookers, middles, and backrow forwards, but likely to most likely lower for 10 minutes. Hookers have possibly trivial or lower average speed for 10 seconds vs. middles and backrow forwards, but very likely greater average running speed for 10 minutes. The identified peak average running speeds of Academy-level match play seem similar to previously reported values of senior professional level.

Heilbronn, BE, Doma, K, Gormann, D, Schumann, M, and Sinclair, WH. Effects of periodized vs. nonperiodized resistance training on army-specific fitness and skills performance. J Strength Cond Res 34(3): 738–753, 2020—This study investigated the effects of periodized resistance training (PRD) and nonperiodized resistance training (NPRD) on army-specific fitness and skills performance measures. Forty-nine serving members of the Australian Army were randomly assigned to 1 of 3 training groups: PRD, NPRD, or no-resistance training (NRT). Resistance training (RT) was performed during PRD and NPRD twice a week for 9 weeks, over a 15-week period, as part of a structured strength and conditioning program. Baseline, mid- and post-testing measures included anthropometric, strength, and army-specific outcome measures. Results indicated that participants who undertook RT significantly improved in 3 repetition maximum (3RM) squat, deadlift, and floor press for both RT groups, at mid- and post-testing (p < 0.05), when compared with NRT. Significant improvements were also observed in 5-km weight load marching postintervention similarly for PRD (p < 0.05) and NPRD (p < 0.01) and simulated fire and movement for both RT groups at both time points (p < 0.01), compared with the NRT group (p > 0.05). Although little difference was observed between periodization models, the current findings suggest greater advantage in developing army-specific performances if a structured RT protocol is included in a generic physical training program compared with a NRT protocol. Therefore, a structured RT program should be considered for military personnel aiming to optimize army-specific fitness and skills performance.

Soria, M, Ansón, M, Lou-Bonafonte, JM, Andrés-Otero, MJ, Puente, JJ, and Escanero, J. Fat oxidation rate as a function of plasma lipid and hormone response in endurance athletes. J Strength Cond Res 34(1): 104–113, 2020—Plasma lipid changes during incremental exercise are not well known. The aim of this study was to investigate the relationship among fat oxidation rate, plasma lipids, and hormone concentrations in well-trained athletes. Twenty-six trained triathletes completed a graded cycle ergometer test to exhaustion increasing by 0.5 W·kg−1 every 10 minutes. Fat oxidation rates were determined using indirect calorimetry. For each individual, maximal fat oxidation (MFO), the intensity at which MFO occurred (Fatmax), and the intensity at which fat oxidation became negligible (Fatmin) were determined. Blood samples for lipids and hormones analysis were collected at the end of each stage of the graded exercise test. All variables studied except insulin showed an increase at the end of incremental protocol with respect to basal levels. Free fatty acid reached significant increase at 60%Vo
2max and maximal levels at 70%Vo
2max. Low-density lipoprotein (LDL) and triglycerides (TG) decreased and showed lowest levels at 60%Vo
2max and reaching significant increases after 80%Vo
2max. High-density lipoprotein reached significant increase at 60%Vo
2max. Adrenaline and noradrenaline increased until the end of the incremental exercise, and significant differences were from 50%Vo
2max. These results suggest that exercise intensities are related to plasma lipids levels. In the zone when lipids oxidation is maximal, plasma LDL and TG variation differs from other lipids. These results may have application for the more adequate exercise intensity prescription to maximize the beneficial effects of exercise.

Ross, R, ALDuhishy, A, and González-Haro, C. Validation of the cosmed K4b2 portable metabolic system during running outdoors.J Strength Cond Res34(1): 124–133, 2020—The aim of this study was to determine the agreement of the K4b2metabolic system in comparison with the Douglas bags (DB) method for determining gas-exchange variables during both indoor treadmill and outdoor running. Nineteen endurance-trained males undertook 3 maximal incremental running tests, separated by at least 2 days: K4b2indoor test (K1), K4b2outdoor test (K2), and DB indoor test. Gas-exchange parameters (Vo2, Vco2, VE, VI, Respiratory Exchange Ratio, FEO2, and FECO2) and heart rate were measured during K1, K2, and DB tests. For most of the variables (Vo2, %Vo2, %Vco2, VE, and VI), the agreement was better for K2 when compared with DB than for K1 when compared with DB. For Vco2, FEO2, and FECO2, the agreement was better between K1 when compared with DB than for K2 when compared with DB. Respiratory Exchange Ratio showed a similar agreement between both conditions (K1 vs. DB and K2 vs. DB). K4b2seems valid for measuring gas-exchange variables during submaximal and maximal running velocities in an outdoor environment. Although K2 mean systematic error (bias) was low, the aleatory error was moderate. These considerations should be taken into account when using K4b2to measure gas-exchange parameters both during indoor and outdoor activities.

Bin Naharudin, MN, Yusof, A, Shaw, H, Stockton, M, Clayton, DJ, and James, LJ. Breakfast omission reduces subsequent resistance exercise performance. J Strength Cond Res 33(7): 1766–1772, 2019—Although much research has examined the influence of morning carbohydrate intake (i.e., breakfast) on endurance performance, little is known about its effects on performance in resistance-type exercise. Sixteen resistance-trained men (age 23 ± 4 years, body mass 77.56 ± 7.13 kg, and height 1.75 ± 0.04 m) who regularly (≥3 day/wk−1) consumed breakfast completed this study. After assessment of 10 repetition maximum (10RM) and familiarization process, subjects completed 2 randomized trials. After an overnight fast, subjects consumed either a typical breakfast meal (containing 1.5 g of carbohydrate/kg; breakfast consumption [BC]) or a water-only breakfast (breakfast omission [BO]). Two hours later, subjects performed 4 sets to failure of back squat and bench press at 90% of their 10RM. Sensations of hunger, fullness, desire to eat, and prospective food consumption were collected before, as well as immediately, 1 hour and 2 hours after BC/BO using 100-mm visual analogue scales. Total repetitions completed were lower during BO for both back squat (BO: 58 ± 11 repetitions; BC: 68 ± 14 repetitions; effect size [ES] = 0.98; p < 0.001) and bench press (BO: 38 ± 5 repetitions; BC: 40 ± 5 repetitions; ES = 1.06; p < 0.001). Fullness was greater, whereas hunger, desire to eat, and prospective food consumption were lower after a meal for BC compared with BO (p < 0.001). The results of this study demonstrate that omission of a pre-exercise breakfast might impair resistance exercise performance in habitual breakfast consumers. Therefore, consumption of a high-carbohydrate meal before resistance exercise might be a prudent strategy to help maximize performance.

J Strength Cond Res 34(7): 2071–2075, 2020—This study aimed to determine the validity of real-time ultra-wideband data generated by a wearable microtechnology unit during rugby league training sessions using a repeated-measures crossover study. Twenty-four semiprofessional rugby league players wore a commercially available microtechnology device (StatSports Apex, Newry, Northern Ireland) during 10 training sessions. Total distance; moderate-speed running (3.6–4.9 m·s−1); high-speed running (5.0–6.9 m·s−1); very high-speed running (≥7 m·s−1); maximum velocity (m·s−1); the number of high-intensity accelerations (≥2.78 m·s−2) and decelerations (≥−2.78 m·s−2); dynamic stress load (AU); and high metabolic load distance (m) were recorded in real time through an Apex beacon over a secured wireless network before being exported to a csv file at the end of the session. The data were then downloaded to a computer after event. To determine the validity of the real-time data, they were compared with the postevent downloaded data using coefficient of variation and Pearson's correlation coefficient. There was almost perfect agreement between real-time and postevent downloaded data for all variables reported. The overall bias effect size scores were all trivial, ranging from 0.00 for total distance and high-speed running up to −0.12 for maximal velocity; Pearson's correlations were either perfect or nearly perfect (r = 0.98–1.00). Irrespective of the movement speed, the data collected by these devices in real time show excellent levels of agreement with postevent downloaded data.

Fairbank, M, Highton, J, Twist, C. Passive heat maintenance after an initial warm-up improves high-intensity activity during an interchange rugby league movement simulation protocol. J Strength Cond Res 35(7): 1981–1986, 2021—This study examined using passive heat maintenance (PHM) to maintain core temperature after a warm-up and its effect on simulated first half running performance in rugby players. Thirteen male rugby players completed this randomized crossover study. Tympanic temperature was taken before a warm-up and then after a further 15 minutes of passive recovery either with (PHM) or without (CON) a PHM garment. Subjects then completed 23 minutes of the rugby league movement simulation protocol (RLMSP-i). Differences in tympanic temperature were unclear between CON and PHM before (35.7 ± 1.3 cf. 36.0 ± 1.1° C; effect size [ES] = 0.20) and during exercise (34.5 ± 0.1 cf. 35.2 ± 0.1° C; ES = 0.26–0.35). High-intensity running (ES = 0.27) and peak sprint speed were higher (ES = 0.46–0.56) during the PHM compared with the CON trial. Time spent above 20 W·kg−1 also increased in the first quartile of the PHM compared with the CON trial (ES = 0.18). All other between trial comparisons of performance were unclear. HRmean (ES = 0.38) was higher in PHM compared with CON, while differences in RPEmean (ES = −0.19) were unclear. There are small to large increases in high-intensity activity performed during a playing bout when rugby players wear a PHM garment after a warm-up. Rugby players should consider PHM during extended periods between a warm-up and starting a match.
Bidirectional Selection for Body Weight on Standing Genetic Variation in a Chicken Model
Authors: Lillie Mette , Honaker Christa F , Siegel Paul B , Carlborg Örjan
Published: February 2019

Experimental populations of model organisms provide valuable opportunities to unravel the genomic impact of selection in a controlled system. The Virginia body weight chicken lines represent a unique resource to investigate signatures of selection in a system where long-term, single-trait, bidirectional selection has been carried out for more than 60 generations. At 55 generations of divergent selection, earlier analyses of pooled genome resequencing data from these lines revealed that 14.2% of the genome showed extreme differentiation between the selected lines, contained within 395 genomic regions. Here, we report more detailed analyses of these data exploring the regions displaying within- and between-line genomic signatures of the bidirectional selection applied in these lines. Despite the strict selection regime for opposite extremes in body weight, this did not result in opposite genomic signatures between the lines. The lines often displayed a duality of the sweep signatures, where an extended region of homozygosity in one line, in contrast to mosaic pattern of heterozygosity in the other line. These haplotype mosaics consisted of short, distinct haploblocks of variable between-line divergence, likely the results of a complex demographic history involving bottlenecks, introgressions and moderate inbreeding. We demonstrate this using the example of complex haplotype mosaicism in the growth1 QTL. These mosaics represent the standing genetic variation available at the onset of selection in the founder population. Selection on standing genetic variation can thus result in different signatures depending on the intensity and direction of selection.

Deplesi sumber daya dihitung melalui perkiraan stok dan tingkat hasil lestari dengan menggunakan model produksi surplus dan estimasi parameter menggunakan metoda Clarke Yoshimoto Pooley (CYP). Nilai deplesi diperoleh dari perkalian volume deplesi dengan unit rent. Hasil penelitian menunjukkan bahwa volume rata-rata deplesi sumber daya ikan tuna dan cakalang pada periode 1992-2015 adalah (-) 2.828 ton per tahun. Rata-rata nilai deplesi sumber daya ikan tuna dan cakalang menunjukkan angka negatif, yaitu (-) Rp131,89 miliar per tahun. Nilai negatif ini menunjukkan bahwa selama periode 1992-2015, stok sumber daya ikan tuna dan cakalang mengalami penurunan sebesar 2.828 ton per tahun dengan nilai potensi kerugian atau kehilangan akibat penurunan stok yang mencapai Rp131,89 miliar per tahun.Title: Tuna And Skipjack Resources Depletion In IndonesiaABSTRACTTuna and Skipjack has a great economic potential in Indonesia. Several studies have shown that these commodities have symptomed of over-fishing in the world, including Indonesia. This study aims to estimate the extent of tuna and skipjack depletion in Indonesia. Resource depletion is calculated through stock estimates and sustainable yield levels using surplus production model and parameter estimation of Clark Yoshimoto Pooley (CYP) method. Depletion value is obtained from multiplication of depletion volume with unit rent. Results of the study showed that the average volume of depletion of tuna and skipjack resources in the period 1992-2015 was (-) 2,828 tons per year. The average value of tuna and skipjack resource depletion showed negative numbers, ie (-) IDR 131.89 billion per year. This negative value indicates that during the period 1992-2015, the stock of tuna and skipjack fish resources decreased by 2.828 tons per year with the potential value of loss or loss due to a decrease in stock which reached IDR131,89 billion per year.

Archaeologies of the Present and Sedimented Futures
Authors: Roddick Andrew
Published: February 2019

In this article, I argue for the merits of a future-oriented ethnoarchaeology that engages recent critiques of ethnoarchaeology and underscores the material traces of our own practices. I develop such an approach by discussing the recent work of the Proyecto Ollero Titicaca Sur, an archaeological, ethnographic, and historic project that explores ceramic craft production in the Lake Titicaca basin, Bolivia. This research was originally framed as an analogy-driven ethnoarchaeological project, connecting dynamics of pottery production with research into crafting communities in the deeper past. However, ongoing work has revealed a community defined not just by the material traces of a historical tradition but also by differential and “arrested” futures. This plurality of futures includes the often-unacknowledged relationship of the ethnoarchaeologist to a larger landscape of development.
METODE PENETAPAN KAFA’AH DALAM ‎JUKLAK NOMOR 1/II/1986 PERSPEKTIF ‎HUKUM ISLAM ‎

Abstract: This study discusses the background of kafa’ah determination method in the Guideline No. 1/II/1986 and how the Islamic legal analysis against the method of kafa’ah determination in the guideline. Method of collecting data is done by the engineering study of documents and interviews. The data are collected through the descriptive method and deductive mindset. At first glance, the kafa’ah determination in this guideline is not in line with Islamic law, but most of the Muslim scholars allow it since the work is also considered in kafa’ah criteria. The determination of kafa’ah in this guideline is on the reason of maslahah, namely being more selective in choosing a partner, maintaining the honor and dignity of a good husband in the family and neighborhood unity of the military, avoiding strife in the household as well as making the vision and mission in the line of duty. In Islamic kafa’ah concept, the assignment of job as a kafa’ah criteria, according to majority the Muslim scholars, is allowed. It is because in addition to religion, the work also needs to be considered as a kafa’ah criteria for the purpose of benefit, namely the creation of sakinah, mawaddah and rahmah family. Based on the above conclusion, it is expected that Army members really need to be selective in choosing a husband/wife by harmonizing with the vision and mission in order to maintain harmony.Abstrak: Penelitian ini membahas tentang apa yang melatarbelakangi adanya metode penetapan kafa’ah dalam Juklak Nomor 1/II/1986 dan bagaimana analisis hukum Islam terhadap metode penetapan kafa’ah dalam juklak nomor 1/II/1986 tersebut. Metode pengumpulan data dilakukan dengan teknik studi dokumen dan wawancara. Data yang telah dihimpun dianalisis menggunakan metode deskriptif  analisis dengan pola pikir deduktif. Jika dilihat sekilas, metode penetapan kafa’ah dalam juklak tersebut terkesan tidak sesuai dengan hukum Islam, tetapi menurut jumhur ulama diperbolehkan, karena pekerjaan juga dipertimbangkan dalam kriteria kafa’ah. Penetapan kafa’ah dalam juklak tersebut dimaksudkan untuk kemaslahatan, yakni agar kowad lebih selektif dalam memilih pasangan, menjaga kehormatan dan harga diri suami baik dalam lingkungan keluarga maupun lingkungan kesatuan TNI, menghindari percekcokan dalam rumah tangga serta untuk menyamakan visi dan misi dalam menjalankan tugas. Dalam konsep kafa’ah dalam perkawinan Islam, penetapan pekerjaan sebagai kriteria kafa’ah, menurut jumhur diperbolehkan, karena selain agama, pekerjaan juga perlu dipertimbangkan sebagai kriteria kafa’ah dengan tujuan untuk kemaslahatan, yaitu terciptanya keluarga yang sakinah mawadah dan rahmah. Berdasarkan kesimpulan di atas, maka diharapkan bagi anggota TNI benar-benar harus selektif dalam memilih calon suami/istri  dengan menselaraskan visi dan misi demi menjaga keharmonisan dalam rumah tangga.Kata Kunci: kafa’ah dan Juklak Nomor 1/II/1986

Published: February 2019

Abstract: This bibliographical research aims to answer the questions of how the determination of the heirs as receivers of Jasa Raharja compensation stated in PP (Peraturan Pemerintah/Government Regulation) No. 18 Year 1965 and how the Islamic law perspective against the determination of the heirs as receivers of Jasa Raharja compensation. The data that obtained by documentation technique are further analyzed by descriptive method and deductive mindset. The research concludes that according to PP No. 18 Year 1965, the heirs are children, widow/widower, and/or the parents of the victim died of road traffic accident with the rule of the receipt and payment of compensation starting from the legitimate widow/widower, legal children, and legal parents. Thus, it can be said that the determination of the heirs within such regulation does not fully implement the provision of the Islamic inheritance system since it only provides Jasa Raharja compensation as a part of estate to the heirs who cannot be stunted (mahjub hirman), such as widow/widower, children, and parents.  However, if it is viewed from the origin compensation of Jasa Raharja that is not coming from the victim but gathered from the owners of the transport equipment, it can be quite fair when the compensation is only given to the nearest heirs.Abstrak: Tulisan ini merupakan hasil penelitian pustaka (library research) yang bertujuan untuk menjawab pertanyaan tentang bagaimana penetapan ahli waris penerima santunan Jasa Raharja dalam PP No. 18 Tahun 1965 dan bagaimana analisis Hukum Islam terhadap penetapan ahli waris penerima santunan Jasa Raharja tersebut. Data penelitian dihimpun dengan menggunakan teknik dokumentasi yang selanjutnya dianalisis menggunakan metode deskriptif analisis dengan pola pikir deduktif. Hasil penelitian menyimpulkan bahwa menurut PP No. 18 Tahun 1965, ahli waris hanyalah anak-anak, janda/ duda, dan/ atau orang tua dari korban mati kecelakaan lalu lintas jalan dengan aturan penerimaan pembayaran santunan dimulai dari jandanya/ dudanya yang sah, kemudian anak-anaknya yang sah dan diakhiri orang tuanya yang sah. Dengan demikian, dapat dikatakan bahwa penetapan ahli waris dalam peraturan tersebut tidak sepenuhnya menerapkan ketentuan hukum kewarisan Islam karena hanya memberikan santunan Jasa Raharja yang merupakan bagian harta waris kepada golongan ahli waris yang tidak bisa ter-hijab hirman, yaitu janda/ duda, anak-anak serta orang tua. Meskipun begitu, jika dilihat dari asal santunan Jasa Raharja yang bukan dari korban, namun terhimpun dari para pemilik/ pengusaha alat angkutan lalu lintas jalan, maka dapat dikatakan cukup adil jika santunan tersebut hanya diberikan kepada ahli waris sedarah yang terdekat saja.Kata Kunci: ahli waris, santunan Jasa Raharja, PP No. 18 Tahun 1965
