Authors: Arshad Abdul Rehman , Khan Tayyaba , Siddiqi Fuad Ahmad , Tahir Shabana , Ahmad Shahid , Qayyum Mohsin
Published: February 2023

Objective: To study electrocardiographic changes during haemodialysis and determine the relationship between electrolyte alterations and acid-base balance.Study Design: Cross-sectional analytical study.

Place and Duration of Study: Haemodialysis Unit, Combined Military Hospital, Peshawar Pakistan, from Jun to Jul 2022.

Methodology: Adult patients with end-stage renal disease on maintenance hemodialysis were selected by convenience sampling. Exclusion criteria included current hospitalization, chest pain during haemodialysis, intra-dialytic hypotension,atrial fibrillation, pericardial effusion, shortening of haemodialysis sessions and unwillingness to participate in the study.Twelve lead electrocardiograms were recorded immediately before the start and end of haemodialysis sessions. At the same time, serum urea, creatinine, potassium, calcium and phosphate were measured. Bicarbonate levels were assessed by venous blood gas analysis. In addition, measurements for heart rate and durations of the PR interval, QRS complex, QT interval andcorrected QT interval reported by ECG machine software were recorded.

Results: There were 35 patients with a mean age of 48.69±11.39 years. Duration of QRS complex increased from 92.83±9.98 to 100.00± 17.94 seconds after haemodialysis (p=0.017). Changes in other parameters were insignificant. QT/QRS and QTc/QRS ratios reduced by 0.27±0.62 and 0.31±0.62 after haemodialysis (p=0.014 and 0.005, respectively). Changes in none of the biochemical parameters during haemodialysis could predict the reduction in QT/QRS or QTc/QRS ratios.

Conclusion: The reduction in the index of cardiac electrophysiological balance during hemodialysis was not related to intradialytic changes in different electrolytes or base content.

Authors: Tao Yu , Tantular Racheline
Published: January 2023

The war in Ukraine has triggered varying responses from people with Chinese heritage worldwide. These responses to the war highlight the diversities within global Chinese communities. They also serve as a lens through which we can observe how different Chinese communities intersect and interact through the internet and social media in a globalised world. This paper creates a few snapshots of juxtaposing opinions on the war in Ukraine among global Chinese communities. It identifies three preliminary patterns underlying these diverse opinions, pointing to directions for subsequent empirical studies. It also discusses how opinions toward the war in Ukraine expose the complex and complicated diversities and connections among global Chinese communities, calling for more scholarly efforts to situate Chinese studies within the global context.

"The study investigates asymmetric impact of government expenditure on the economic growth of Nigeria using secondary data that spans through 1981 through 2018. In capturing the asymmetric impact, the study adopted the Non-Linear Auto-regressive Distributed Lag (NARDL) model. Government expenditure components (recurrent and capital expenditure) were decomposed to positive and negative changes due to government review. From the result, it was confirmed that in the short-run, both positive and negative changes in recurrent and capital expenditure had a significant positive impact on economic growth in Nigeria at different time lag. In the long-run, positive changes in recurrent expenditure have a negative impact on economic growth, while negative changes have a positive significant impact on economic growth in Nigeria. Positive changes in capital expenditure have a positive impact on economic growth, while negative changes has a negative 5% significant impact on economic growth. It was concluded from the findings that government expenditure plans has a significant impact on the economic growth of Nigeria in the short-run and long-run. Therefore, it is recommended that government should rebalance its plans between capital and recurrent expenditure to enhance its growth target."

Published: January 2023

Abstract. Aerosol-cloud interaction is considered one of the largest sources of uncertainties in radiative forcing estimations. To better understand the role of black carbon aerosol as cloud nucleus and the impact of clouds on its vertical distribution in the Arctic, we report airborne in-situ measurements of refractory black carbon aerosol particles (rBC) in the European Arctic near Svalbard during the ACLOUD campaign held in summer 2017. rBC was measured with a single particle soot photometer on board of the research aircraft “Polar 6” from the lowest atmospheric layer up to approximately 3500 m asl. During in-cloud flight transects, rBC particles contained in liquid droplets (rBC residuals) were sampled through a counterflow virtual impactor (CVI). Overall, the presence of low-level clouds was associated with a radical change in the concentration and size distribution of rBC particles in the boundary layer compared to the free troposphere. Four flights conducted in the presence of inside-inversion, surface-coupled, mixed-phase clouds over sea ice, were selected to address the variability of rBC particles sampled above, below and within the cloud layer. We show that the properties of rBC such as concentration, size and mixing state drastically changed from the above to the below cloud layers, but also within the cloud layers from cloud top to cloud bottom. Our results might suggest the occurrence of a cloud-mediated transformation cycle of rBC particles in the boundary layer which includes activation, cloud processing, and sub-cloud release of processed rBC agglomerates. In the case of persistent low-level Arctic clouds, this cycle may reiterate multiple times, adding one additional degree of complexity to the understanding of cloud processing of black carbon particles in the Arctic.
Unique benthic foraminiferal communities (stained) in diverse environments of sub-Antarctic fjords, South Georgia
Authors: Majewski Wojciech , Szczuciński Witold , Gooday Andrew J.
Published: February 2023

Abstract. Sub-Antarctic fjords are among the environments most affected by the recent climate change. In our dynamically changing world, it is essential to monitor changes in these vulnerable settings. Here, we present a baseline study of “living” (rose-bengal-stained) benthic foraminifera from fjords of South Georgia, including fjords with and without tidewater glaciers. Their distribution is analyzed in the light of new fjord water and sediment property data, including grain size and sorting, total organic carbon, total sulfur, and δ13C of bulk organic matter. Four well-defined foraminiferal assemblages are recognized. Miliammina earlandi dominates in the most restricted, near-shore and glacier-proximal habitats, Cassidulinoides aff. parkerianus in mid-fjord areas, and Globocassidulina aff. rossensis and an assemblage dominated by Ammobaculites rostratus, Reophax subfusiformis, and Astrononion echolsi are in the outer parts of the fjords. Miliammina earlandi can tolerate strong glacial influence, including high sedimentation rates in fjord heads and sediment anoxia, as inferred from sediment color and total organic carbon / sulfur ratios. This versatile species thrives both in the food-poor inner reaches of fjords that receive mainly refractory petrogenic organic matter from glacial meltwater and in shallow-water coves, where it benefits from an abundant supply of fresh, terrestrial, and marine organic matter. A smooth-walled variant of C. aff. parkerianus, apparently endemic to South Georgia, is the calcareous rotaliid best adapted to inner-fjord conditions characterized by moderate glacial influence and sedimentation rates and showing no preference for particular sedimentary redox conditions. The outer parts of fjords with clear, well-oxygenated bottom water are inhabited by G. aff. rossensis. Ammobaculites rostratus, R. subfusiformis, and A. echolsi dominate in the deepest-water settings, with water salinities ≥ 33.9 PSU and temperatures 0.2–1.4 ∘C, characteristic of winter water and Upper Circumpolar Deep Water. The inner- and mid-fjord foraminiferal assemblages seem specific to South Georgia, although with continued warming and deglaciation, they may become more widespread in the Southern Ocean.

Published: February 2023

Abstract. Anaerobic microbial sulfate reduction and oxidative sulfur cycling have been studied in long sediment cores mainly acquired as part of IODP explorations. The most remarkable observation in many of these studies is the existence of an active sulfur cycle in the deep subsurface sediments that have very low organic carbon content and are presumably refractory. Here we investigate the interstitial sulfate concentrations and sulfur isotope ratios in a 290 m long core collected from the eastern Arabian Sea at a water depth of 2663 m. Continuous decrease in pore water-sulfate concentrations with depth (up to 75 mbsf) coupled with enrichment in δ34SSO4 values suggests organoclastic sulfate reduction (OSR) processes attributed to the activity of sulfate-reducing bacteria (SRB) and retention of labile organic substrates amenable to the SRBs. Below a depth of 75 mbsf, the absence of a further reduction in sulfate concentrations indicates insufficient labile substrate to drive SRB. An increase in sulfate concentrations at the deeper subsurface (below 128.5 mbsf) coupled with decreasing δ34SSO4 values may be attributed to a ferric-oxyhydroxide driven oxidation of Fe-sulfide. This study reveals that even under deep aerobic water columns, organic matter may continue to be a source of labile organic substrates at significantly deeper subsurface. Enhanced sulfate concentrations in the deeper depths may be attributed to the oxidation of sulfides via ferric-oxyhydroxides buried deep within the sediment. A microbiological investigation may reveal further details of the sulfur cycle at the deep surface.
Causes of the weak emergent constraint on climate sensitivity at the Last Glacial Maximum
Authors: Renoult Martin , Sagoo Navjit , Zhu Jiang , Mauritsen Thorsten
Published: February 2023

Abstract. The use of paleoclimates to constrain the equilibrium climate sensitivity (ECS) has seen a growing interest. In particular, the Last Glacial Maximum (LGM) and the mid-Pliocene warm period have been used in emergent-constraint approaches using simulations from the Paleoclimate Modelling Intercomparison Project (PMIP). Despite lower uncertainties regarding geological proxy data for the LGM in comparison with the Pliocene, the robustness of the emergent constraint between LGM temperature and ECS is weaker at both global and regional scales. Here, we investigate the climate of the LGM in models through different PMIP generations and how various factors in the atmosphere, ocean, land surface and cryosphere contribute to the spread of the model ensemble. Certain factors have a large impact on an emergent constraint, such as state dependency in climate feedbacks or model dependency on ice sheet forcing. Other factors, such as models being out of energetic balance and sea surface temperature not responding below −1.8 ∘C in polar regions, have a limited influence. We quantify some of the contributions and find that they mostly have extratropical origins. Contrary to what has previously been suggested, from a statistical point of view, the PMIP model generations do not differ substantially. Moreover, we show that the lack of high- or low-ECS models in the ensembles critically limits the strength and reliability of the emergent constraints. Single-model ensembles may be promising tools for the future of LGM emergent constraint, as they permit a large range of ECS and reduce the noise from inter-model structural issues. Finally, we provide recommendations for a paleo-based emergent constraint and notably which paleoclimate is ideal for such an approach.
An improved Approximate Bayesian Computation approach for high-dimensional posterior exploration of hydrological models
Authors: Liu Song , She Dunxian , Zhang Liping , Xia Jun
Published: January 2023

Abstract. The Approximate Bayesian computation (ABC) methods provide a powerful tool for sampling from Bayesian posteriors for cases where we can simulate samples, but we have no access to an explicit expression of the likelihood function. The Simulated Annealing ABC (SABC) algorithm has been proposed to achieve a fast convergence to an unbiased approximation to the posterior by adaptively decreasing an initially coarse tolerance value. However, this algorithm uses a rather simplistic random walk Metropolis (RWM) sampler to generate trial moves in a Markov chain and always requires an excessive number of model evaluations for approximating the posterior, which inevitably lowers the sampling efficiency and limits its applications in more complex hydrologic modelling practices. Inspired by the advances made in Markov Chain Monte Carlo (MCMC) methods, we incorporated an adaptive Differential Evolution scheme to enhance the efficiency of SABC sampling. This scheme has its roots within Differential Evolution Markov Chains (DE-MC), and additionally utilizes a self-adaptive randomized subspace sampling strategy to optimally select the dimensions of parameters to be updated each time a proposal is generated. The superiority of the modified SABC (mSABC) over the original SABC algorithm was demonstrated through a SAC-SMA application to the Danjiangkou Reservoir region (DRR). The case study results showed that mSABC was far more efficient with lower computation costs and higher acceptance rates, and achieved higher numerical accuracy than the original SABC algorithm. mSABC also resulted in a better overall prediction of streamflow time series and signatures. The introduction of more advanced MCMC sampler into SABC helps to speed up convergence to the approximate posterior while achieving better model performance, which significantly widens the applicability of SABC to complex posterior exploration problems.
Detecting anomalous sea-level states in North Sea tide gauge data using an autoassociative neural network
Authors: Wahle Kathrin , Stanev Emil V. , Staneva Joanna
Published: February 2023

Abstract. The sea level in the North Sea is densely monitored by tide gauges. The data they provide can be used to solve different scientific and practical
problems, including the validation of numerical models and the detection of extreme events. This study focuses on the detection of sea-level states with anomalous spatial correlations using autoassociative neural networks
(AANNs), trained with different sets of observation- and model-based data.
Such sea-level configurations are related to nonlinear ocean dynamics;
therefore, neural networks appear to be the right candidate for their
identification. The proposed network can be used to accurately detect such
anomalies and localize them. We demonstrate that the atmospheric conditions
under which anomalous sea-level states occur are characterized by high wind
tendencies and pressure anomalies. The results show the potential of AANNs
for accurately detecting the occurrence of such events. We show that the
method works with AANNs trained on tide gauge records as well as with AANN
trained with model-based sea surface height outputs. The latter can be used
to enhance the representation of anomalous sea-level events in ocean models. Quantitative analysis of such states may help assess and improve numerical model quality in the future as well as provide new insights into the nonlinear processes involved. This method has the advantage of being easily applicable to any tide gauge array without preprocessing the data or
acquiring any additional information.
The Impact of Climate Change on Extreme Winds over Northern Europe According to CMIP6
Authors: Larsén Xiaoli Guo , Imberger Marc , Hannesdóttir Ásta , Hahmann Andrea N.
Published: January 2023

Abstract. We study the possible effect of climate change on the extreme wind over Northern Europe using data from 18 models of the Sixth Phase of the Coupled Model Intercomparison Project (CMIP6) and the high-emission SSP585 scenario. We use the spectral correction method to correct the 6-hourly wind speeds and calculate the 50-year wind at an equivalent temporal resolution of 10 minutes, consistent with the International Electrotechnical Commission (IEC) standard. We assess the quality of the CMIP6 wind data during the historical period through comparison to the spatial patterns of the extreme wind in three reanalysis data. We obtain the possible effect of climate change through the comparison of the extreme wind parameters, including the 50-year wind and the 95 %-percentile of the wind speed, and the change in turbine class at 50 m, 100 m and 200 m, between a near future period (2020–2049) and the historic period (1980–2009). The analysis shows an overall increase in the extreme winds in the North Sea and the southern Baltic Sea, but a decrease over the Scandinavian Peninsula and most of the Baltic Sea. However, the analysis is inconclusive to whether higher or lower classes of turbines will be installed in this area in the future.

We discuss the best methods available for computing the gamma function Γ(z) in arbitrary-precision arithmetic with rigorous error bounds. We address different cases: rational, algebraic, real or complex arguments; large or small arguments; low or high precision; with or without precomputation. The methods also cover the log-gamma function log Γ(z), the digamma function ψ(z), and derivatives Γ⁽ⁿ⁾(z) and ψ⁽ⁿ⁾(z). Besides attempting to summarize the existing state of the art, we present some new formulas, estimates, bounds and algorithmic improvements and discuss implementation results.
Blends have decent numerical properties
Authors: Corless Robert
Published: February 2023

A "blend" is a two-point Hermite interpolational polynomial, typically of quite high degree. This note shows that implementing them in a double Horner evaluation scheme has good backward error, and also shows that the Lebesgue constant for a balanced blend or nearly balanced blend on the interval [0,1] is bounded by 2, independently of the grade or degree of the approximation. On [-1,1], which is a more natural interval for comparison, it is of course unbounded, but grows only like 2√(m/π) where 2m+1 is the grade of approximation. I also show that the quadrature schemes for balanced blends amplify errors only by O( ln(m) ).
Daytime Napping Benefits Passing Performance and Scanning Activity in Elite Soccer Players
Authors: Nishida Masaki , Okano Shuta , Ichinose Atsushi , Suyama Shutaro , Youn Sumi
Published: January 2023

The present study explored the effect of a daytime napping opportunity on scanning activity, which is an essential component of successful soccer performance. Fourteen male elite collegiate soccer players performed the Trail Making Test (TMT), which was used to assess complex visual attention. In addition, a soccer passing test, modified with reference to the Loughborough Soccer Passing Test, was used to evaluate passing performance as well as scanning activity. A cross-over design was applied to examine nap and no-nap interventions. Participants (N = 14, mean age: 21.6 SD = 0.5 years, height: 1.73 ± 0.06 m, body mass: 67.1 ± 4.5 kg) were randomly allocated to a midday nap (40 minutes) or no-nap group. Subjective sleepiness was measured using the Karolinska Sleepiness Scale, and perceptive fatigue was evaluated by the visual analog scale. There were no significant differences in subjective measurements or TMT between the nap and no-nap groups. However, the performance time for the passing test and scanning activity was significantly shorter (p < 0.001) and scanning activity was significantly more frequent in the nap condition than in the no-nap condition (p < 0.00005). These results suggest that daytime napping is beneficial for soccer-related cognitive function, represented by visuospatial processing and decision-making, and particularly as a potential countermeasure to mental fatigue. Considering that inadequate sleep and residual fatigue are commonly observed in elite soccer, this finding may have practical implications for the preparation of players.

In this research, it was aimed to examine the relationship between the effective leadership characteristics perceived by teachers working in private educational institutions towards their managers and their work motivations. In this context, regression analysis was carried out to determine the effect of the perceptions of teachers working in special education institutions about effective leadership characteristics on job motivation. In addition, some findings have been reached based on the data obtained about whether the perception of effective leadership characteristics in private educational institutions is a significant predictor of extrinsic motivation. The current situation of teachers working in special education institutions related to excitement has been examined in this context. Being excited; It means approaching life with energy and excitement, a lively and active life. It has been determined that the ability of educational administrators to produce alternative solutions when faced with any problem and the energy they need to solve the problem depends on being excited and positive.

HEAD-TOE DISTANCE AS A SIMPLE MEASURE TO EVALUATE AMPLITUDE OF CIRCLES ON POMMEL HORSE
Authors: Fujihara Toshiyuki , Gervais Pierre , Irwin Gareth
Published: January 2023

To develop scientifically-valid tools to monitor performance in practice, a critical question is what to measure. On pommel horse, the importance of fundamental skills called circles is uncontroversial, and one of the key performance qualities of circles is the amplitude of the movement. Previous studies have used joint angles or the magnitude of a body part’s trajectory to evaluate the amplitude, but we hypothesized that the distance between two points, namely a head and toes might be substituted despite its relative simplicity. This study examined the use of Head-Toe Distance (HTD) normalized by the gymnast’s body height as a simple variable to potentially evaluate the amplitude of circles. The kinematic data of circles performed by 18 elite gymnasts were collected with a Qualisys motion capture system operating at 100 Hz. HTD and its horizontal component, HTDh, were computed along with their relationships to the outcome scores given by the official judges, as well as the other amplitude variables: the horizontal diameters of shoulder and ankle trajectories; the body flexion angle; and in the rear support position, the shoulder extension angle and the head position. The results supported HTDh, rather than HTD, for its potential usage as a single variable to evaluate the amplitude of circles. The benefits of HTDh compared to the other variables lies in its potential validity despite its relative simplicity in assessment. Because computing HTDh requires only the positional data of the head and toes, it may have greater practical applications as an evaluative tool in gymnastics.
Fas cell surface death receptor/Fas ligand genetic variants in gastric cancer patients: A case control study
Authors:   Department of Biology, Faculty of Sciences, Razi University, Kermanshah, Iran., Bidmeshkipour Ali
Published: January 2023

Background & objectives: Various studies have suggested a correlation between Fas Cell Surface Death Receptor/Fas Ligand (FAS/FASL) variants and multiple types of cancers. The present study aimed to investigate the association between FAS-670A/G and FASL-844C/T and the synergistic effects of both variants on the risk of Gastric Cancer (GC) in the Kurdish population of West of Iran. Methods: This study was conducted by polymerase chain reaction-restriction fragment length polymorphism technique using MvaI and BsrDI restriction enzymes in 98 GC patients and 103 healthy control individuals. Results: According to the obtained results, a significant association (P=0.008) of FASL polymorphism among GC patients and the control group was detected. Furthermore, no significant differences were found in the FAS polymorphism frequencies between GC patients and the control group. Codominant and dominant models in FASL polymorphism showed significant protective effects against GC [odds ratio (OR) =0.307, 95% confidence interval (CI) (0.134-0.705), P=0.005; OR=0.205, 95% CI (0.058-0.718), P=0.013 and OR=0.295, 95% CI (0.129-0.673), P=0.004 for models of codominant CC vs. CT, codominant CC vs. TT and dominant, respectively]. Furthermore, the presence of both FAS-670G and FASL-844T alleles represented a significant protective effect against GC occurrence [OR=0.420, 95% CI (0.181-0.975), P=0.043]. Interpretation & conclusions: So far, we believe this is the first study the results of which suggest that FASL gene variation and its synergistic effects with FAS gene could be associated with the risk of GC in the Kurdish population in the west of Iran.
In-stent stenosis of the internal carotid artery
Authors:   The American British Cowdray Medical Center, General hospital in Mexico City, Mexico, Hayashi Mercad Cesar
Published: January 2023

At present, the treatment of internal carotid artery stenosis has been extensively modified, passing from endarterectomy to balloon plasty and stent placement, generating a significant reduction in surgical risk [1]. In-stent stenosis is reported in up to 30% of cases and patients generally present with a transient ischemic attack or stroke [2]. Doppler ultrasound is an excellent tool for the evaluation of this pathology, accurately monitoring the percentage of in-stent stenosis and the hemodynamic repercussion it represents. In-stent stenosis of 50% correlates with velocities of up to 225 cm/s and greater than 70% correlates with velocities of up to 350 cm/s [3].
Incorporation of research curriculum in specialty training: The need for a paradigm shift

Published: January 2023

Residents are the backbone of every large medical center that aims to strengthen and nourish the upcoming crop of medical personal. The professional prospect of a resident is largely based on their core subject knowledge, the tenacity to practice these core principles and their ability to add to it by academic activities and didactic thinking. Academic and research activities bear the brunt of spillover from clinical and surgical responsibilities of a residents, and this must be curtailed to maximize the involvement of residents in research activities. A possible con of these activities can be the deduction of these academic hours from the surgical training and eventual compromise. Some would argue that research activities can be a double edged sword, but in order to cultivate progressive thinking amongst the newer generation and to improve the quality of care of our patients, these didactic activities should be made a priority rather than a privilege. Moreover, it should be encouraged and controlled at a national level to ensure the availability of resources and curriculum to strengthen this practice.

Günümüzde artan banka ve kredi kartı kullanımı tüketicilerin nakit harcama eğilimini de değiştirmiştir. Mevcut ekonomik koşullar ve gelecek ekonomik beklentiler doğrultusunda şekillenen tüketici güven endeksi ile fiyatlar genel seviyesinde yaşanan sürekli artış olarak ifade edilen enflasyonun banka ve kredi kartı harcamalarıyla ilişkisi çalışmanın motivasyonunu oluşturmaktadır. Türkiye’de banka ve kredi kartı harcamaları ile tüketici güven endeksi ve tüketici fiyat endeksinin uzun dönemli ilişkisi 2014 Mart-2022 Kasım dönemi için ARDL analizi ile incelenmiştir. Aralarında uzun dönemli eşbütünleşme ilişkisi bulunan serilerin uzun dönem katsayıları tespit edilmeden önce modelin kararlılığı tanı testleri ile sınanmıştır. Uzun dönem katsayı sonuçlarına göre tüketici fiyat endeksinin istatistiki olarak anlamlı olmadığı sonucuna ulaşılırken, tüketici güven endeksinin istatistiki olarak anlamlı ve negatif ilişkisi olduğu tespit edilmiştir. Kısa dönemli ilişki ise hata düzeltme modeli ile incelenmiş, cari dönemde bank a ve kredi kartı harcamalarında yaşanan kısa dönemli bir sapmanın uzun dönemde %23,73 oranında düzeltildiği anlaşılmıştır.

Published: February 2023

PT XYZ memiliki bisnis seperti halnya Integreated Supply Chain (ISC) yang berperan penting dalam menjaga operasional supply minyak mentah, bahan bakar minyak (BBM), dan liquified petroleum gas (LPG) nasional dengan tetap mengedepankan keekonomian. Dalam proses pengangkutan produk (BBM), ISC menggunakan sarana transportasi kapal yag sesuai dengan kondisi geografis di Indonesia. Namun, pemilihan transportasi kapal ini justru menjadi tantangan tersendiri bagi PT XYZ mengingat pemetaan kegiatan yang terkait proses loading dan discharge di dermaga belum mencakup target waktu yang ditentukan, hingga masih banyak waktu yang kurang optimal. Kondisi existing loading dan discharge BBM di Terminal BBM XYZ Kepulauan XYZ menggunakan selang dan Marine Loading Arm (MLA) dengan salah satu produknya adalah Pertamax Turbo. Kondisi existing untuk discharge produk Pertamax Turbo di Jetty 5 masih menggunakan selang (cargo hose) 4” dengan maksimal Flow rate 350 kl/jam, dengan mobilisasi manual oleh tenaga manusia dan crane. Di jetty 5 sendiri terdapat MLA (Marine Loading Arm) yang digunakan untuk operasional produk Premium dan Pertamax 92. Dikarenakan sama-sama merupakan produk light oil, sehingga ada peluang dimanfaatkan untuk operasional produk Pertamax Turbo. Berdasarkan data jetty limitation penggunaan MLA (Marine Loading Arm) untuk operasional discharge produk light oil, kemampuan flow ratenya maksimal 1000 kl/jam. Sehingga peluang peningkatan kemampuan discharge secara operasional lebih cepat. Berdasarkan identifikasi aspek dampak lingkungan dan bahaya resiko pekerjaan pemasangan hose/selang di Terminal BBM XYZ Kepulauan XYZtermasuk dalam kategori resiko tinggi. Namun, saat ini masih menggunakan selang untuk discharge/bongkaran Pertamax Turbo maka waktu yang dubutuhkan adalah 13 jam 20 menit. Jika kedepannya menggunakan Marine Loading Arm (MLA) untuk discharge/bongkaran Pertamax Turbo maka waktu yang dubutuhkan adalah 4 jam 13 menit. Sehingga, dapat menghemat waktu sebanyak 9 jam 6 menit untuk tiap kali discharge/bongkaran. Jika menggunakan selang biaya charter kapal untuk discharge/bongkaran Pertamax Turbo tiap kali bongkarannya adalah Rp 80.802.131,32, sedangkan jika menggunakan Marine Loading Arm (MLA) biaya charter kapal untuk discharge/bongkaran Pertamax Turbo adalah Rp 25.362.319,29. Sehingga biaya charter kapal yang dapat dihemat jika kedepannya discharge/bongkaran Pertamax Turbo menggunakan Marine Loading Arm (MLA) adalah Rp 55.439.812,03.
