Published: August 2022

Cumi-cumi (Loligo sp.) merupakan binatang lunak dengan tubuh berbentuk silindris. Sirip-siripnya berbentuk triangular atau radar yang menjadi satu pada ujungnya. Pada kepalanya disekitar lubang mulutnya terdapat 10 tentakel yang dilengkapi dengan alat penghisap (sucker) dan merupakan sumber protein hewani yang mana komponen utama penyusun proteinnya adalah asam amino. Penelitian ini bertujuan untuk mengetahui pengaruh lama waktu penggaraman yang berbeda pada proses pengolahan cumi-cumi terhadap kadar protein dan profil asam amino. Hasil penelitian menunjukkan bahwa perlakuan lama waktu penggaraman yang berbeda memberikan pengaruh yang tidak berbeda nyata terhadap kadar protein berdasarkan hasil Analysis of Variance (ANOVA) α 5%.  Kesimpulan dari penelitian ini adalah pengaruh lama waktu penggaraman cumi yang berbeda tidak berpengaruh terhadap kadar protein, Hasil analisa kadar protein tertinggi ada pada perlakuan C yaitu penggaraman selama 5 hari sebesar 15,09% sedangkan untuk profil asam amino lisin  sebesar 1,38% dari perlakuan 0 yaitu cumi-cumi segar merupakan jenis asam amino esensial tertinggi dari profil asam amino penyusun protein cumi, sedangkan jenis asam amino non esensial tertinggi adalah asam glutamat sebesar 2,79% dari perlakuan 0 yaitu cumi-cumi segar.

Ikan sepat rawa merupakan salah satu bahan makanan yang memiliki sumber protein relatif murah dibandingkan dengan sumber protein lainnya. Sebagai salah satu pengawetan dari ikan sepat rawa, teknik penggaraman digunakan karena kebanyakan bakteria, fungi dan organisme patogenik lainnya tidak dapat bertahan hidup dalam sebuah lingkungan dengan kadar garam yang tinggi. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi garam yang berbeda terhadap prosil asam lemak ikan sepat rawa. Rancangan penelitian ini bersifat eksperimental dengan penambahan konsentrasi garam yang berbeda memberikan pengaruh terhadap prosil asam lemak ikan sepat rawa. Hasil menunjukkan bahwa konsentrasi garam yang berbeda memberikan pengaruh yang berbeda nyata terhadap profil asam lemak ikan sepat rawa. Jumlah kadar asam lemak tertinggi yaitu B dengan konsentrasi garam 10% sebesar 65,74 % dan untuk profil asam lemak terdapat 29 jenis dengan asam lemak terbanyak yaitu asam palmitat (asam lemak jenuh) sebesar 20,89 %, asam oleat (asam lemak tak jenuh tunggal) sebesar 17,86% dan asam linolenat (asam lemak tak jenuh jamak) sebesar 3,70%.
 
Sepat rawa fish is a food that has a relatively cheap source of protein compared to other protein sources. As one of the preservation of three sepat rawa fish, the salting technique is used because most bacteria, fungi and other pathogenic organisms cannot survive in high salinity environments. This study aims to determine the effect of different salt concentrations on the fatty acid prosyl of three sepat rawa fish. The design of this research was experimental with the addition of different salt concentrations to affect the fatty acid prosyl of sepat rawa fish. The results showed that the difference in salt concentration had a significant effect on the fatty acid profile of three sepat rawa fish. The most fatty acid content is B with a salt concentration of 10% of 65.74% and for the fatty acid profile there are 29 types with the most fatty acids, namely palmitic acid (saturated fatty acid) of 20,89%, oleic acid (monounsaturated fat acids) by 17,86% and linolenic acid (poly unsaturated fatty acid) by 3,70%.

Self-care is often lacking in nursing students worldwide. The objectives for this study were to discover the current self-care practices of one group of entry level undergraduate nursing students, the students’ understanding of self-care, and the students’ preferences for self-care interventions aimed at improving self-care. Quantitative and quantitative measures were used to measure the students’ current self-care practices, needs, and recommendations for interventions to be used in future semesters to improve nursing student self-care. The students were found to generally be deficient in areas related to nutrition, obtaining healthcare information or guidance, pacing themselves to avoid exhaustion, and performing relaxation exercises. They scored well on areas related to psychosocial self-care, such as believing their life has meaning or having meaningful relationships. Several suggestions were made by the students for encouraging nursing student self-care. Nursing students are often lacking in self-care. It is important for nursing programs worldwide to develop and encourage student self-care.

On 11 July 2019, during the Rodent Eradication Program on Lord Howe Island using aerial and ground rodentbaiting, the recovery of dead non-target birds included a recently dead boobook Ninox sp. found on a resident’s property. Two Tyto species were also recovered. Despite automated sound-recording equipment stationed within the forests of the Island, no records of Ninox vocalisations were made before discovery of the boobook specimen; however, two instances of Ninox owl calls were reported anecdotally within The Settlement. There was speculation from some Island residents that the recovered boobook could have been an individual of the extinct endemic subspecies, the Lord Howe Boobook N. novaeseelandiae albaria. The boobook was forwarded to the Australian Museum for further visual scrutiny, collection of morphometric data, DNA analysis, and preparation for the Australian Museum collection. There was overlap in plumage and morphological measurements between both the Tasmanian Boobook (N. leucopsis) and the nominate Tasman Morepork from New Zealand (N. n. novaeseelandiae), but the specimen was distinct from the larger Australian mainland N. boobook. DNA analysis provided conclusive evidence that the bird was a male N. leucopsis, exhibiting an overall clean-white spotted pattern and darker brown coloration. The occurrence of a Ninox species on Lord Howe Island is the first record in more than 50 years and should prompt further exploration of the dispersal and possible migration of boobooks from Tasmania.

Kamu Harcamalarının İnsani Gelişme Üzerindeki Etkisinin Westerlund (2005) Panel Eşbütünleşme Testi ile Analizi
Authors: ERGEN Eren
Published: August 2022

Ekonomik birimlerin birlikte yaşaması toplumsal ihtiyaçları ortaya çıkarmıştır. Toplumsal ihtiyaçların karşılanması ise devletin kamu harcamalarını gerçekleştirmesiyle mümkün olmaktadır. Ekonomi literatüründe kamu harcamaları hakkında iki temel görüş bulunmaktadır. Bunlardan ilki kamu harcamalarının minimum düzeyde olmasını savunmaktadır. İkinci görüşe göre ise devletin böyle bir sınırlaması olmaması gerekmektedir. 1929 krizinden sonra ikinci görüş ağırlık kazanmıştır. Dolayısıyla devlet, kamu harcamalarını eğitim ve sağlık gibi alanlara da yöneltmeye başlamıştır. Böylece ülkelerin insani gelişimi de desteklenmiştir. Kamu harcamalarının insani gelişme üzerindeki etkisine yönelik literatürün yoğun ilgisi bulunmaktadır. Nitekim artan insani gelişim neticesinde ekonomik büyüme de hızlanabilmektedir. Çalışmanın amacı kamu harcamalarının insani gelişim üzerinde etkisinin olup olmadığının analiz edilmesidir. Bu doğrultuda çalışmada 1996-2019 dönemini kapsayan yıllık veriler kullanılmış ve üst orta gelir grubunda yer alan 30 ülke ele alınmıştır. Analizde Westerlund (2005) panel CUSUM eşbütünleşme testi kullanılmıştır. Katsayıların tahmin edilmesi için FMOLS ve DOLS katsayı tahmincileri hesaplanmıştır. Elde edilen bulgulara göre kamu harcamaları ve insani gelişim endeksi arasında eşbütünleşme ilişkisi bulunmuştur. Ayrıca katsayı tahminlerine göre kamu harcamalarında yaşanılan artışın insani gelişim endeksini olumlu yönde etkilediği görülmüştür. En iyi bilgimizle üst orta gelir grubunda yer alan ülkeler için kamu harcamalarının insani gelişim endeksi ile ilişkisini analiz eden çalışmanın bulunmaması ise bu çalışmanın literatürde katkısı olarak ifade edilebilir.
Importance of Real-Time Acquisition of Casing Gas Rate, PIP, and Fluid Level Data on Maximizing Drawdown in Highly Dynamic Horizontally Produced Wells
Authors: Pons Victoria , Hovakimyan Robert
Published: August 2022

Longer laterals, better perforations and larger frac jobs have all enabled increased production capabilities. However, production optimization practices, which were developed decades ago, are still in use today, and severely limit the ability to aggressively draw wells down. The data provided in the most common fluid level processes does not meet the challenges generated by fluctuating well dynamics and conditions. The irregularity and inconsistency of current fluid level measurement systems and downhole cards provide an incomplete snapshot of the well conditions when a more complete solution is needed for optimization. Moreover, pump-off controller technology cannot discern gas interference from pumped-off scenarios resulting in unplanned shutdown and lost production.

A growing number of wells being produced on sucker rod pump are offering high PIP and high fluid levels above pump, yet production is being limited due to gas interference caused by reservoir dynamics. Pumping through these ever-changing scenarios more aggressively is often the solution, yet this change in optimization practices cannot take place without ensuring the system is not overloaded and rod buckling is not taking place. To have this conversation, casing gas rates, accurate PIP and fluid levels must be acquired and automatically analyzed at a much higher frequency. With a permanent, automated fluid level system, reservoir and fluid data is continuously attained.

Paired with properly tuned algorithms and current optimization practices, these data points give a clearer and more complete story of what rod pumped wells experience continuously throughout the day. Additionally, more information about the reservoir is produced than previously available.

This paper offers insight on current shortcomings in optimization logic for highly dynamic unconventional wells and introduces a proposed methodology to improve runtimes in high gas interference and high fluid level scenarios while extending the life of the installation and equipment. Results showing the methodology's effectiveness at improving production and enhancing drawdown over time are presented.

Published: August 2022

Sciatic notch tumours of the intra-pelvic variety are rare lesions and commonly arise from the sciatic nerve. These are usually benign neurogenic tumours and the most common of them is schwannoma. Conventional laparotomy techniques have associated surgical morbidity and significant blood loss. The advent of robotic systems and refinement in robotic-assisted surgical techniques to access deep lying pre-sacral lesions has offered a novel way to surgically handle such lesions thereby reducing morbidity, hospital stay and blood loss. Here we are presenting a case of non-discogenic sciatica which was attributed to superior gluteal nerve tumour and was surgically resected using robotic-assisted technique.
Application of tunnel mathematics for solving the steady Lamé and Navier-Stokes equations.
Authors: G. Shvydkyi O.
Published: August 2022

The theory of functions of a complex variable is a hybrid of vector algebra and ordinary algebra. It makes it possible to work with vector quantities as with algebraic ones. The modern theory of functions of a complex variable was created by the French mathematician Augustin Cauchy (1789–1857), later it was rapidly developed and found its application in solving various problems of physics - in aerodynamics, hydrodynamics, elasticity theory, etc. However, this theory is used exclusively for solving problems on the plane. Therefore, the next natural step is to extend this theory into space, so that we could obtain the solution of physical problems directly in space. The creation of such a theory is associated with some serious problems, for example, the appearance of so-called zero divisors, spatial complex numbers that are not equal to zero but when multiplying for some reason give zero. There is also a Frobenius theorem which prohibits the propagation of complex numbers into a space without abandoning some ordinary algebraic operations (for example, commutative multiplication). In this article an attempt is made to construct a theory of spatial complex functions (shortly, tunnel mathematics) in which zero divisors do not appear and all the usual algebraic operations are preserved. The possibility of applying this theory to some problems of the theory of elasticity and hydrodynamics (the steady Lamé and Navier-Stokes equations) is also considered.

Owing to the importance gained by the Nile tilapia (Oreochromis niloticus) in recent years, it is necessary to use tools for the control and management of finishing fish farms. The work was conducted with the objective of developing a bioeconomic simulator for use as a tool to assist finishing fish farms and support the management decisions taken. One tool was developed through the combination of spreadsheets that align the centers of technical and economic control, making it possible to obtain economic and financial results by filling in data (inputs), which is real or can be simulated. The spreadsheets are interconnected, and after the data are inserted, the results are automatically generated. Data from its performance indicators and technicians were used for the creation of four scenarios: Monophase x Nursery (MonoN), Monophase x Cage (MonoC), Multiphase x Nursery (MultiN), and Multiphase x Cage (MultiC). The MultiC system had the highest revenue (US$288,996.16) and net income (US$72,563.52), resulting in a better use of resources, with high density, reaching productivity of 283.41 kg/m³. In the financial evaluation, all systems were acceptable to investors, with MultiC presenting the best results, with an Internal Rate of Return of 20.41% and a six-year payback. The simulator was able to carry out the calculations and present results close to those found in the finishing fish farms, being able to be used with other combinations of data. The simulator proved to be an efficient and easy-to-use tool, providing several automatic analyses aimed at assisting producers and researchers.

Broiler meat is known for its nutritional value, availability, and low price. Although, broilers are more sensitive to environmental conditions and need a specific environment for optimum production. However, global warming and natural disasters are important obstacles to broiler production. Therefore, we conducted this study to reveal the broiler production status throughout the year in a subtropical region. In our study, we selected the years 2019, 2020, and 2022. The study area included Noakhali and Lakshimpur, located in the southern part of Bangladesh. We selected 10 smallholder broiler farms following specific conditions and collected information at the end of each month for analysis. The body weight of broilers was significantly lower in July than in other months. However, the mortality was significantly lower in July than in other months of the year. Nonetheless, the prevalence of viral disease was higher in the winter season (January, February, and December). Although, the metabolic disease prevalence was higher in October, a high prevalence of bacterial disease was found in April. These results suggest that high temperatures decrease broiler production while broilers are more susceptible to viral disease in the winter season.

The bay of Port-Bouët is threatened by extreme sea level (ESL) events, which result from the combination of storm tide, wave runup and sea level rise (SLR). This study provides comprehensive present-day and future ESL elevation scenarios at local scale along the bay, to understand the evolution of the phenomenon and promote adaptation at neighbourhood level. The methodological steps involve firstly, a reconstruction of historical storm tide and wave runup data using respectively a hydrodynamic model (D-flow FM) and the empirical model of Stockdon et al. Secondly, the generalised pareto distribution (GPD) model fitted to the peaks-over-thresholds (POT) method is applied on the data to calculate their extreme return values. Thirdly, we combine extreme storm tide and wave runup through the joint probability method to obtain present-day ESLs. Lastly, the present-day ESLs are integrated with the recent SLR projection to provide ESL estimates for the years 2030, 2050 and 2100. Results show that the present-day ESL are relatively high with the 100-year return levels being 4.37m, 4.97m and 4.48m at Vridi, Petit-Bassam and Sogephia respectively. Future SLR is expected to increase the current ESL elevations by 0.49m, 0.62m or 0.84m by 2100 depending on the climate change scenarios. The developed ESL scenarios can be used to assess potential coastal flood risk in the study area for sustainable and effective coastal management and future planning.

Background: Hereditary haemochromatosis is the most common known inherited disease in Caucasians. Pathological iron accumulation in tissues is known to cause cirrhosis, hepatocellular carcinoma and other manifestations. While early diagnosis and treatment can prevent the consequences of this disease, reports of this disorder suggest that it is underdiagnosed. Aims: The purpose of the current study was to compare the expected prevalence of hereditary haemochromatosis, based on the positive predictive values of increased transferrin saturation, to the actual number of patients that have been diagnosed.Methods: Medical record data of 362,275 adult patients were collected at one tertiary care center. An increase in transferrin saturation (above 50% for women and 60% for men) is a marker for hereditary haemochromatosis with 86% positive predictive value.Results: 1597 patients from the cohort had increased transferrin saturation. Considering the positive predictive values, the expected number of patients having hereditary haemochromatosis would be 1377 (0.38% of the cohort). 74 patients from the cohort were previously diagnosed with haemochromatosis or iron overload. The expected prevalence of hereditary haemochromatosis in the cohort is at least 18.6 times higher than that was actually diagnosed. Conclusion: Hereditary haemochromatosis is an underdiagnosed disease. We found that the expected prevalence in our cohort is comparable with reported population data. The discrepancy between the number of actually diagnosed patients and the expected number is enormous. Increasing the awareness for the diagnosis of this disorder and potentially changing the current recommendations for screening are necessary towards improving the clinical outcomes in these patients.

The Henon Map forms one of the most-studied two dimensional discrete-time dynamical system that exhibits chaotic behavior. The Hénon map takes a point (xn, yn) in the plane and maps it to a new point (xn+1, yn+1). In this paper, a pulse generator based on chaotic Henon map is proposed. It consists of a Henon map function subcircuit to realize the Henon map and a subcircuit to carry out the iterative operation. The Henon map subcircuit comprises of operational amplifiers, multipliers, delay elements and resistors whereas, the iterative subcircuit is implemented with a simple design without any clock control. The proposed design can be used to realize Henon map and also to generate chaotic pulse train, with a controllable time interval and pulse position. The proposed circuit is designed and implemented using Multisim. The chaotic nature of the generated pulse train and also the time interval between the consecutive pulses can be verified by the calculation of its Lyapunov Exponents.

Background: Medical education increasingly relies on digital learning materials. Despite recognition by the Association of American Medical Colleges Institute for Improving Medical Education, medical education design often fails to consider quality multimedia design principles. Further, the AAMC-IIME issued a call to study the role of design principles in medical education. Thus, the current study investigated the cognitive and affective effects of redesigning PowerPoint slides used to support pharmacology content during the preclinical years of medical school training.Methods: Researchers implemented a quasi-experimental design, using traditionally-designed slides with a Control group (n=32) and slides redesigned to follow principles from the Cognitive Theory of Multimedia Learning with an Experimental Group (n=28). Participants completed a post-survey incorporating the Situational Interest Survey for Multimedia to indicate motivational engagement with the media. Students in the Experimental group also responded to additional preference questions. Researchers analyzed survey responses and students’ scores in pharmacology-related coursework across the preclinical Foundations Phase of training to determine impact on achievement and motivation.Results: Findings related to learner achievement showed a modest but significant increase at the Experimental site compared to the Control site (101%, p = 0.043). Additionally, participants in the Experimental group (M=4.85, SD=0.25) indicated a significantly higher average triggered situational interest than the Control group (M=3.23, SD=1.40, t=-6.33, p<0.001). Similarly, the interest rating of the Experimental group (M=4.87, SD=0.24) was significantly greater than that of the Control group (M=3.89, SD=0.86, t=-6.824, p<0.001). Moreover, results further indicated significant differences in the maintained-feeling and maintained-value constructs, and all participants in the Experimental group indicated a preference for the redesigned slides.Conclusions: The findings provide strong evidence in support of using the Cognitive Theory of Multimedia Learning design principles to intentionally design media in medical education. In addition to increased achievement scores, students in the Experimental group demonstrated significantly higher levels of situational interest, especially triggered interest and maintained-feeling interest. Medical education learning designers should seriously consider redesigning media to achieve similar results.

PurposeFocal lesions of the liver are usually detected by enhanced CT and further diagnosed by enhanced MR in clinical practice. The harmful effects of repeated contrast use in CT and MR, and the subjectivity of conventional imaging increase the risk of misdiagnosis. Our aim is to establish a radiomics nomogram based on T2-weighted imaging for differentiating hepatocellular carcinoma and benign liver lesions with rich blood supply and to estimate the enhancive value to the traditional imaging diagnosis.MethodsThe retrospective study analyzed the imaging and clinical data of 144 patients with hepatocellular carcinoma (n=101) and benign blood-rich lesions of the liver (n=43) pathologically confirmed. These patients were randomly assigned to the training cohort (n=100) and the validation cohort (n=44). We developed three prediction models - a radiomic model, a clinical model, and a fusion model that combined radiomics score (Rad-score) with clinical factors. Comparing the predictive performance of three models, we obtained the best prediction model, which was then compared with the diagnostic efficacy of junior and senior radiologists. The efficacy was evaluated using the area under receiver operating characteristic curve (ROC).ResultsFour radiomics features and three clinical factors (age, sex, lesion location) were chosen for construction of the radiomics model and the clinical model, respectively. Comparing to the radiomics model and the clinical model, the fusion model showed significant discrimination capability in the training set (AUC, 0.972; 95%CI 0.918 - 0.995) and the validation set (AUC, 0.943; 95%CI 0.829 - 0.990). And it was statistically better than the junior radiologist and the senior radiologist in the training cohort (p=0.007 and p=0.005, respectively).ConclusionsThe T2WI-based radiomics nomogram greatly complements the flaw of traditional imaging diagnosis and avoid the reuse of contrast agents. It might facilitate early clinical diagnosis and precision treatment with performed exceedingly favorable predictive efficacy in differentiating HCC and BLLs with rich blood supply.
Training Interdisciplinary Statistical Collaborators: A Comparative Case Study

Published: August 2022

Statistics is an inherently collaborative discipline as individuals across academia, government, and industry all rely on data to answer relevant questions and innovate in their fields. As a result, there is a growing body of research regarding how to teach interdisciplinary collaboration skills to statistics students. However, much of this work relies on data that do not objectively assess collaboration. Additionally, prior research lacks detailed evidence of how to assess quality of collaboration skills. In this case study, we compare the statistical collaboration skills of both a team of students and an expert collaborator on two components of effective statistical collaboration: structuring a statistical collaboration meeting and communicating with a domain expert during a statistical collaboration meeting. We find that students can facilitate meetings and communicate comparably well to an expert statistical collaborator, but that expert collaborators may be better able to facilitate meetings and communicate to develop strong relationships with domain experts, an important element for high-quality and long-term statistical collaboration projects. Further work is needed to generalize these findings to a larger population, but these results begin to inform the field regarding effective ways to teach specific statistical collaboration skills.
