Efektifitas Proses Ozonisasi Studi Kasus: Sungai Cikapundung
Authors: Maudila Dwinda
Published: June 2020

ABSTRAK Kualitas air permukaan biasanya didominasi oleh kandungan bahan organik. Hal yang dapat mempengaruhi kandungan bahan organik salah satunya adalah perubahan tata guna lahan. Apabila kandungan bahan organik tinggi maka DO akan menurun, sehingga memungkinkan adanya degradasi bahan organik oleh bakteri anaerob pada sungai. Ozon merupakan oksidator kuat yang dapat mengoksidasi bahan organik dan anorganik dalam air, hasil dekomposisinya dapat menghasilkan OH radikal yang bersifat tidak selektif. Penelitian ini bertujuan mengetahui karakteristik bahan organik di Sungai Cikapundung serta mengetahui penyisihan kekeruhan dan BOD dengan menggunakan proses ozonisasi. Proses ozonisasi dilakukan pada reaktor batch selama 60 menit dengan interval kontak waktu 10 menit pada ozon kontaktor yang bervolume 1,5 liter. Parameter yang diukur meliputi pH, suhu, DHL, kekeruhan, COD, BOD, alkalinitas, UV254 dan KSO yang didasarkan pada SNI dan SMWW. Hasil yang didapatkan pada karakteristik yaitu dengan adanya perubahan tata guna lahan dari daerah yang belum terbangun menjadi daerah terbangun menyebabkan kualitas air Sungai Cikapundung mengalami penurunan dari Hulu menuju Hilir, hal ini dapat dilihat dari adanya peningkatan kekeruhan pada Sungai Cikapundung Hulu, Tengah Hilir berturut-turut adalah 1,97 NTU, 19,33 NTU dan 20 NTU. Peningkatan BOD pada Sungai Cikapundung Hulu, Tengah dan Hilir adalah 2,38 mg/L, 26,72 mg/L dan 35,68 mg/L. Proses ozonisasi menyebabkan penurunan nilai kekeruhan pada Sungai Cikapundung Hulu, Tengah, Hilir sebesar 35,02%, 38,84% dan 34,16% serta peningkatan nilai BOD sebesar 57,97%, 63,53% dan 60,23%. Karakteristik bahan organik pada Sungai Cikapundung semakin hilir semakin meningkat, dengan adanya proses ozonisasi dapat menurunkan nilai kekeruhan dan meningkatkan konsentrasi BOD yang menunjukkan adanya perubahan senyawa organik komplek menjadi senyawa organik sederhana.

Authors: Matkovskyi Andrii , Skryl Vitaliia , Shtanko Ruslana
Published: June 2020

Financial inclusion of the region is a means of making full use of the financial services industry's tools, which ultimately contributes to the long-term economic growth of the region, as it stimulates innovation, mobilizes savings and supports investment. The paper analyzes the current level of financial inclusion of the Poltava region. The study showed that the current level of financial inclusion of the Poltava region is low. Surveys of the respondents showed that there is a large disproportionate level of financial inclusion among urban and rural population. The rural population is limited in financial services. There is still a significant lack of confidence in financial institutions. All this slows down the processes of full involvement of the population in financial inclusion and creates a shadow sector. However, remediation is observed in urgent action by both the state and local authorities and financial institutions. Continuous information in the media and social networks in the future will be able to restore confidence in financial institutions and thus increase not only the level of financial inclusion, but also every inhabitant of the Poltava region.

Authors: Vereshchagin Alexander , Reznichenko Irina , Bychin Nikolay
Published: June 2020

The article concerns the research specificity of model systems such as cocoa butter – palm olein, cocoa butter – sucrose and cocoa butter – glucose syrup by the differential scanning calorimetry (DSC) method. The researchers run experiments in the temperature range from –100 to –50°C at a heating rate of 10 °C/min. In the cacao butter – palm olein system an eutectic occurs with a palm olein content of 30.0 % indicating the limited solubility of palm olein in cocoa butter. In the cocoa butter – sucrose system, cocoa butter crystallizes as in the α-form (10,0– 30,0; 60.0–90.0 % MK), and as a mixture of α-and β-forms of MK (40.0; 50,0; 70,0 and 80.0 %). Sucrose stabilizes low-temperature polymorphic modifications of cocoa butter. In the cocoa butter – glucose syrup system, temperature of samples melting is 21-22 °C. This composition is promising for use as a filling of confectionery products and glazes production. In this regard, a man can use glucose syrup only in the candy cases production. The role of surfactants used for the formation and stabilization of cocoa butter polymorphs and increasing the thermal stability of the shock-lad without the introduction of palm stearin requires separate consideration.

Screening for hepatocellular carcinoma in chronic liver disease: a systematic review and meta-analysis of randomized controlled trials comparing screening methodologies
Authors: O'Connell James , Rooney Siobhan
Published: June 2020

Background

Globally, hepatocellular carcinoma (HCC) is the fifth most prevalent cancer and the second most common cause of cancer-related mortality. HCC is often asymptomatic until an advanced stage. Current guidelines recommend ultrasound surveillance with or without measurement of serum alpha-fetoprotein. Our objective was to determine if screening for HCC is beneficial or harmful in patients with chronic liver disease. Primary outcomes were all-cause mortality and quality of life. Secondary outcomes were mortality due to HCC, the number of cases of HCC detected, and adverse events.

Methods

This is a systematic review and meta-analysis of data from randomized controlled trials. To be included trials had to randomize patients to either an HCC screening group or non-screening group, randomize patients to different screening frequencies or randomize patients to different screening methods. All published reports of randomized trials on screening for HCC were eligible for inclusion, irrespective of the language of publication. Studies had to include patients with chronic liver disease. Data extraction were performed independently by two reviewers.

Results

When screening with six-monthly alpha-fetoprotein and ultrasound abdomen was compared to no screening there was no evidence of difference in HCC related mortality when adjusted for clustering across a range of intracluster correlation coefficients (Intracluster coefficient (ICC) 0.02, odds ratio (OR) 0.60, 95% confidence interval (CI) 0.31-1.15). Screening with six-monthly alpha-fetoprotein when compared to a single alpha-fetoprotein check did not result in a statistically significant difference in all-cause mortality (OR 1.02, 95% confidence interval (CI) 0.65-1.60), mortality due to HCC (OR 1.01, 95% CI 0.57-1.78) or the number of HCC detected (OR 1.11 95% CI 0.64-1.92). There was no evidence of difference in all-cause mortality (OR 0.81, 95% CI 0.26-2.53), mortality due to hepatocellular carcinoma (OR 0.81, 95% CI 0.26-2.53) or the number of patients with HCC detected (OR 1.09 95% CI 0.40-2.99) when twice-a-year ultrasound was compared with annual CT. There was no statistically significant difference when screening more frequently was compared to less frequently in terms of all-cause mortality (OR 0.86, 95% CI 0.56-1.32), mortality due to hepatocellular carcinoma (OR 1.42, 95% CI 0.55-3.64) and the number of cases of hepatocellular carcinoma detected (OR 0.90 95% CI 0.47-1.71).

Conclusion

There is currently insufficient evidence from randomized controlled trials to support routine screening for HCC in patients with chronic liver disease.
Impact of Corporate Social Performance on Financial Performance: Case of Firms Listed on the Stock Exchange of Casablanca
Authors: Jamel Lamia , Ben Ltaifa Monia , Elnagar Ahmed K , Derbali Abdelkader
Published: June 2020

This paper examines empirically the impact of corporate social performance (CSP) on financial performance (FP). The study relates to a panel of 32 firms listed on the Stock Exchange of Casablanca during the period of study from 2011 to 2017. The empirical findings obtained, by linear regressions on panel data, clearly find the lack of impact of the corporate social performance on the financial performance measured by the Return on Investment (ROI), Return on Equity (ROE) and Earnings Per Share (EPS) ratios. The influence of corporate social performance on financial performance is statistically insignificant. The financial performance of firms classified or not socially efficient are almost identical. Finally, the results obtained clearly show the absence of this causal link between corporate social performance (CSP) on financial performance (FP), which confirms the research hypothesis. Finally, since the relationship between these two performances could be non-linear, we can deepen this article using econometric methods that can analyze the non-linear effect such as quantile regression and the regime-change model.

Orphan Heritable Thoracic Aortic Diseases and Pregnancy. Modern Outlooks and Guidance
Authors: Siromakha S. O.
Published: June 2020

Pregnancy is a period of high risk for all patients with aortic pathology. Heritable thoracic aortic diseases (HTAD) refer to aortopathies with a high risk of formation and dissection of thoracic aortic aneurysm (TAA). HTAD are caused by a mutation of a certain gene. This paper reviews current perceptions of manifestations of rare hereditary diseases of the thoracic aorta during pregnancy and general recommendations for the medical care of these patients. To date, 16 genes (or loci of unidentified genes) are known to be associated with the development of thoracic aortic aneurysm, and since many families with a history of TAA (about 70%) have no pathogenic changes in any of these 16 genes, additional genes associated with HTAD have not yet been identified.

In this paper, HTAD are considered which occur (or are identified) quite rare but provide a significant risk for patients, which is significantly increased during pregnancy (multisystemic smooth muscle dysfunction syndrome, Meester Lois syndrome, LOX and PRKG1 genes mutations, vascular Ehlers-Danlos syndrome, mutations in TGFB2, TGFBR1, TGFBR2, SMAD3 loci, Loeys-Dietz syndrome). The article analyzes the frequency of occurrence of the most threatening complication of HTAD – acute aortic dissection – in various syndromes, defines general recommendations for the examination of patients with HTAD, recommendations for conservative treatment of these patients. Recommendations for the patients (especially fertility women) concerning the preventive cardiac surgery are also summarized in the paper. These principles of pregravidary preparation and multidisciplinary medical support during pregnancy are the most effective prophylactic measures for major cardiac events and maternal death. Pregnancy heart team that has been working in Ukraine since 2013 does all its best to organize medical support for every pregnant woman with suspected HTAD. In this context, it is very important to collaborate with general practitioners and genetics to “catch” such patients before they become pregnant or in very early terms.

Поставлено і розв’язано для деяких окремих випадків, важливих в практичній діяльності, обернену задачу побудови толерантних інтервалів. Розв’язок отримано для планування експерименту в непараметричному випадку, а також для рівномірного розподілу, показникового розподілу, розподілу Вейбулла, нормального розподілу, логарифмічно нормального розподілу. Запропоновано чисельні методи розв’язання поставлених задач, доступних для найбільш поширених програмних продуктів. Прямою задачею побудови толерантних інтервалів в параметричному випадку названо задачу, в якій при заданому об'ємі вибірки, відомому закону розподілу і його параметрів, визначених за вибірковими даними, заданому рівні довіри (статистичній надійності) необхідно визначити межі можливих значень випадкової величини, в яких може знаходитися задана частка вибірки. За відсутності відомостей про вид закону розподілу вибірки розглянуто розв’язок задачі в непараметричному випадку. При виконанні розрахунків чисельних прикладів прийнято наступні умови. Для частки генеральної сукупності прийнято стандартні умови: 0,75; 0,90; 0,95; 0,99; для заданої статистичної надійності прийнято значення: 0,90; 0,95; 0,99. Прийнято, що вибірка містить не менш ніж 30 спостережень. Обмеження на об'єм вибірки обумовлені тим, що, по-перше, при меншому об'ємі вибірки необхідне створення спеціалізованих програмних продуктів, по-друге, обробка даних, отриманих по вибірках меншого об’єму, не завжди має змістовний сенс. При розв’язанні задачі в непараметричному випадку отримано таблицю, яка дозволяє обрати розв’язок поставленої задачі для заданих умов. Показано, що вибірки більше, ніж 300 спостережень не дають істотних змін у розв’язку задачі. Для всіх перерахованих розподілів визначені, для нижнього і верхнього значень меж толерантних інтервалів, об'єми вибірок, що забезпечують необхідні ймовірнісні характеристики: частку вибірки в генеральній сукупності і її статистичну надійність. Для нормального розподілу поставлена задача вирішена для варіанту двостороннього толерантного інтервалу.

Одне із основних завдань техніки зв'язку – це забезпечення високої якості передачі інформації в умовах дії завад. У випадку, що розглядається, досліджується завадостійка передача числової вимірювальної інформації при передачі показів вимірювальних приладів обліку, наприклад, кількості спожитої води, електроенергії, тощо. В такому випадку важливим фактором підвищення якості передачі інформації є використання завадостійких кодів для кодування десяткових цифр, з допомогою яких передається інформація з вимірювальних приладів. В даній роботі використовуються рівноважні коди, які прості за своєю структурою і в той же час мають непогану завадостійкість як в симетричних каналах передачі інформації, так і в несиметричних. Кодові комбінації цих кодів складаються з п’яти розрядів, два з яких одиничні, а три нульові. Порушення кількості одиниць і відповідно кількості нулів в кодовій комбінації є ознакою її помилки. Однак оцінка рівня завадостійкості двійково-десяткових рівноважних кодів не має на сьогодні закінченого вигляду і тому потребує подальших досліджень. Робота, що розглядається, спрямована на проведення такої оцінки. Вона дозволить в кінцевому підсумку оцінити ефективність роботи системи передачі числових даних, яка використовує двійково-десяткові рівноважні коди. Ця оцінка підтверджується програмним моделюванням системи передачі двійково-десяткових цифр, результати якого надані в вигляді графіків. Таке моделювання потрібно проводити для кожної системи передачі вимірювальної інформації окремо, тому що ймовірність помилкових переходів для них різна. У роботі розглянута математична модель визна чення ймовірності помилкового переходу рівноважної кодової комбінації, що передається. При створенні математичної моделі враховані особливості, які притаманні рівноважному коду. Побудовані алгоритми і програма для здійснення оцінки завадостійкості кодів та її відповідності різним класам достовірності, з допомогою якої проведена оцінка завадостійкості двійково-десяткових рівноважних кодів. Аналіз результатів дослідження показав, що застосування рівноважних кодів забезпечує необхідний рівень захисту вимірювальної інформації у відповідності до вимог стандартів при введенні мінімального рівня надлишковості. За результатами дослідження зроблено висновок, що надана методика оцінки завадостійкості та ефективності кодування двійково-десяткових чисел рівноважними кодами дає можливість ефективно використовувати її на практиці.
