PenentuanKoefisienPelimpah Untuk Perhitungan Debit Air Yang Lewat Di Bendung Way Umpu
Authors: Sidik Budi sayogyo
Published: April 2022

Jumlah debit yang bisa dialirkan dari suatu bending sangat dipengaruhi oleh koefisien pelimpah yang ditentukan oleh bentuk pelimpah bending itu sendiri. Bentuk pelimpah sangat dipengaruhi oleh tinggi air diatas pelimpah serta jari-jari kelengkungan pelimpah. BendungWay Umpu merupakan bending Teknis yang mengairi sawah pada Daerah Irigasi (D.I) Way Umpu di kecamatan Banjit dan Baradatu, Kabupaten Way Kanan. Daerah Irigasi (D.I.) Way Umpu dibangun Pemerintah pada tahun anggaran 1976–1977 dan 1980–1981 menggunakan sumber dana APBN dan Loan OECF yang mempunyai luas layanan 7.500Ha.Dengan kondisi bendung yang sudah teknis pembagian air menjadi lebih akurat dan ketinggian air bisa diatur sesuai dengan kebutuhan para anggota Perkumpulan Petani Pemakai Air (P3A). Semenjak pembangunan sampai sekarang koefisien pelimpah Bendung Way Umpu belum pernah dilakukan analisis penyesuaian(kalibrasi). Penentuan debit dihitung berdasarkan perkiraan angka koefisien pengaliran(c) dikalikan dengan tinggi air diatas mercu dan lebar bending efektif. Dari gambaran ini menunjukkan bahwa angka koefisien pengaliran yang pasti tidaklah dilakukan berdasarkan penelitian/kalibrasi yang mendalam melainkan berdasarkan perkiraan dari bentuk pelimpah bending sebesar 0,97. Dalam operasi dan pemeliharaan khususnya dalam pembagian debit air perlu sekali dilakukan analisis nilai koefisien limpasan yang sesuai dengan karakteristik yang ada di lapangan untuk memberikan kepastian dalam hal pemberian air. Terlebih lagi beberapa bagian pelimpah telah mengalami perubahan kecil seperti plesteran yang lepas dan permukaan yang lebih kasar. Dari hasil penelitian didapatkan besarnya angka kalibrasi pelimpah sebesar 0,747 sedangkan besarnya koefisen pada pintu penguras sebesar 0,64 dan koefisien pada pintu intake sebesar 0,85.

Peran Insinyur dalam Rangka Menaikan Daya Saing Industri Karet dalam memanfaatkan Sumber Daya Alam Indonesia
Authors: Wema Augustia Ermalasari
Published: April 2022

Pada Industri Karet khususnya pada Industri Ban yaitu menggunakan 75% bahan baku yang mengandung kimia karet Import (BR,ZNO,Stearic Acid, N330, Accelerator, MBTS, MBT, Wax, RPO, Pine Tar Oil, Homogenizing Agent, Antioxidant TMQ/I, Antioxidant SPC, Antioxidant 6PPD) dan 25% mengandung bahan baku local 9karet alam, kaolin & sulfur) sehingga harga yang tertekan adalah harga bahan baku local ini tidak dapat diupgrade karena 75% cost produksi bahan baku import. Bahan baku ini terkait dengan dollar maka selalu ada kenaikan harga. Oleh karena itu kami menanfaatkan Sumber Daya Alam Indonesia untuk memproduksi Karet Antioksidan (Antiox-TMQ) yang mengganti produk import. Yang mana karet antioksidan ditentukan oleh nilai Aktifitas Antioksidan (IC50) yaitu konsentrasi antioksdian yang dibutuhkan untuk meredam 50% radikal bebas, DPPH dalam pengujian berlaku sebagai radikal bebas. Aktifitas Antioksidant semakin kecil (Nilai IC50) berarti semakin bagus karena dalam penggunaannya hanya sedikit sudah mampu meredam radikal bebas, sehingga produk yang dihasilkan dalam kondisi stabil. Antioksidan merupakan molekul yang mampu memperlambat atau mencegah proses oksidasi. Oksidasi adalah reaksi kimia yang dapat menghasilkan radikal bebas yang dapat merusak produk. Karena radikal bebas dapat merusak dan terjadinya perubahan properties seperti (Hardness, Tensile Strength, Elongation dan blooming(jamur).

Authors:   Department of Automation, North China Electric Power University, Baoding, Hebei, China, Chen Wenying , Li Jingyu
Published: April 2022

For a class of network control systems with both data packet dropout and network communication delay problems, a new robust model predictive control method with compensation function is proposed. Considering that the system has interference problems, in the two cases of long-delay and short-delay, the packet loss problem is established as a Bernoulli sequence, and then a discrete NCS model based on the state observer is obtained. The state observer in the model can deal with the data packet dropout compensate and predict the state of the long-delay problem. Through linear matrix inequality and Lyapunov method, the controller is designed to obtain sufficient conditions for the closed-loop system to be exponentially stable and meet the specified performance indicators. Finally, compared with the method without any compensation measures, the method in this paper can get better control effect.

Authors: Vorobyeva IV , Bulava EV , Moshetova LK , Pinchuk AV
Published: April 2022

Simultaneous pancreas and kidney transplantation (SPK) provides effective treatment in patients with type 1 diabetes mellitus (T1DM) and end-stage renal failure (ESRF), mitigating the hyperglycemia and uremic syndrome. The study aimed at the assessment of morphofunctional status of the macula and macular hemodynamics in patients with T1DM after SPK. The study enrolled 45 patients subdivided into three groups: Group A — patients with T1DM after SPK; Group B — patients with T1DM and ESRF, maintained on programmed hemodialysis (PH), on waiting list for SPK; and Group C — individuals without ophthalmic or systemic pathologies. All patients were subject to the standard ophthalmological examination complemented by measurements of the central retinal thickness (CRT) and the average perfusion density (PD) in four vascular layers: superficial capillary plexus of the retina (SCP), deep capillary plexus of the retina (DCP), choriocapillaris, and choroid. The patients after SPK had significantly lower CRT (241 ± 33 µm in Group A, 309±10 µm in Group B; p < 0.05) and significantly higher PD of the macular region in both the retina (Group A: SCP — 19.0 ± 1.6%, DCP — 10.7 ± 1.3%; Group B: SCP — 11.7 ± 0.8%, DCP — 4.8 ± 0.8%; p < 0.05) and the choroid (Group A: choriocapillaris — 28.1 ± 1.8%, choroid — 31.3 ± 1.6%; Group B: choriocapillaris — 20.4 ± 1.6%, choroid — 21.8 ± 1.3%; p < 0.05), as well as significantly higher visual acuity (Group A: 0.7 ± 0.1; Group B: 0.5 ± 0.1; p < 0.05) and macular light threshold (Group A: 25.9 ± 1.4 dB; Group B: 22.3 ± 1.1 dB; p < 0.05) compared with the patients on PH. Thus, the normalization of carbohydrate metabolism and the mitigation of uremic syndrome in patients with T1DM and ESRF after SPK favorably affect the functional condition of the macular area, as indicated by the improvement in macular blood flow and visual functions.
Hysteresis and stochastic convergence in Eurozone unemployment rates: evidence from panel unit roots with smooth breaks and asymmetric dynamics
Authors: Corakci Aysegul , Omay Tolga , Hasanov Mubariz
Published: April 2022

Research background: Studying the dynamic characteristics of unemployment rate is crucial for both economic theory and macroeconomic policies. Despite numerous research, the empirical evidence about stochastic behaviour of the unemployment rate remains disputable. It has been widely agreed that most economic variables, including unemployment rates, are characterized by both structural breaks and nonlinearities. However, a little work is done to examine both features simultaneously.
Purpose of the article: In this paper, we analyse the stationarity properties of unemployment rates of Euro area member countries. Also, we aim to test stochastic convergence of unemployment rates among member countries. Our empirical procedures explicitly allow for simultaneous gradual breaks and nonlinearities in the series.
Methods: This paper develops a new unit root test procedure for panel data, allowing for both gradual structural breaks and asymmetric adjustment towards equilibrium. We carry out Monte Carlo simulations to examine small sample performance of the proposed test procedure and compare it to the existing test procedures. We apply the newly proposed test to examine the stochastic properties of the unemployment rates of Euro-member countries as well as relative unemployment rates vis-?-vis the Eurozone unemployment rate.
Findings & value added: We find that the newly developed test procedure outperforms existing tests in highly nonlinear settings. Also, these tests reject the null hypothesis of unit root in more cases when compared to the existing tests. We find stationarity in the series only after allowing for structural breaks in the data generating process. Allowing for nonlinear and asymmetric adjustment in addition to gradual breaks provides evidence of stationarity in more cases. Furthermore, our results suggest that relative unemployment rate series are stationary, providing evidence in favour of stochastic convergence in unemployment rates. Overall, our results imply a limited room for coordinated economic policy to fight unemployment in the Eurozone.
How do SMEs from different countries perceive export impediments depending on their firm-level characteristics? System approach
Authors: Civelek Mehmet , Krajčík Vladimír
Published: April 2022

Research background: The differences in the legal structures, tax rates, and cultural-linguistic issues of various countries have always been a significant concern for SMEs in their exporting activities and internationalization processes. However, since firm-level characteristics might provide some advantages or disadvantages in their operations, their perceptions of export impediments might vary across size, age, and sector groups.
Purpose of the article: This paper investigates the perceptions of export impediments by 408 larger-smaller, older-younger, and manufacturing-nonmanufacturing Czech, Slovakian and Hungarian SMEs in a country-based perspective.
Methods: The researchers use the random sampling method to create research samples and employ an internet-mediated questionnaire to collect the research data. The researchers use both Independent Sample T-test and ANOVA analyses to find differences between size, age, and sector groups.
Findings & value added: While the differences exist between the perceptions of Slovakian larger-smaller and manufacturing-nonmanufacturing SMEs regarding cultural differences, the perceptions of legal and tax-related export impediments by SMEs do not differ depending on their age, size, and sector. This paper contributes to the literature by confirming various perceptions of SMEs in different countries and different characteristics regarding export obstacles and providing an entity-specific and international scope that policymakers and SMEs can benefit from. Awareness of the policymakers regarding the results of this paper that includes differences and similarities in SMEs? perceptions of export barriers might make them have close interactions with SMEs to reduce SMEs? concerns regarding their export risks. On the other hand, SMEs that are aware of the results of this paper can be more interested in having a broader network that includes close relationships not only with intermediary firms, but also with governments to overcome the export impediments.

Published: April 2022

In this study, the effects of spray drying parameters on organic blueberry extract were investigated. High amounts of bioactive compounds were extracted from blueberry by solvent extraction. Response surface methodology was applied for the optimization of spray drying conditions. Extract mass percentage of feed mixture (m/m in dry basis 15-50%), air inlet temperature (120-150°C) and solid content of feed (20-40°Brix) were independent variables. Operational efficiency (yield) and phenolic retention were responses. Maltodextrin was used as an encapsulating agent. The optimum extract mass percentage, temperature and solid feed content were estimated as 19.51% (m/m) extract, 120°C and 20.03°Brix, respectively. The maximum levels of responses under optimum conditions were obtained as operational efficiency of 91.20% and phenolic retention of 87.12%. It was found that the most important variable for bioactive compound retention was the extract mass percentage. Encapsulated powder had 3.19% moisture content, and contained 5.54 mg gallic acid equivalents (GAE), 1.52 mg cyanidin-3-glucoside (C3G), and 46.41 μmol Trolox equivalents (TE) per gram dry powder. DPPH free radical scavenging activity value (EC50) of powder was 8.14 mg soluble solids/mL. Bioactive powder obtained could be considered as a possible functional food ingredient. In conclusion, blueberry extract powder could be efficiently produced by spray drying.

Authors: ATAMER Zeynep
Published: April 2022

In this study, different adhesives manufactured by using various casein powders (micellar casein, αS-, β- and ĸ-casein fractions, sodium caseinate and calcium caseinate) were investigated for their properties and potential application in the food industry. Casein-based adhesives using different sources of caseins were produced and the differences in their adhesive strength were determined. For the isolation of casein fractions, the methods of selective solubility, precipitation and a decanter centrifuge (for separation of precipitated casein and supernatant) were used. Achieved purities of αS-, β- and κ-casein fractions were higher than 25, 91 and 54%, respectively. Results showed that the type of casein raw material used in the production of adhesives had an influence on the adhesive properties and the highest adhesive strength was achieved with the enriched αS-casein fraction and micellar casein.

Published: April 2022

Genetics, the biology of heredity provides a unifying conceptual framework linking all the life sciences and has been identified as one of the difficult concepts in biology to teach and learn. The presence of terminologies with meanings different from common usage and the teaching strategies employed by teachers have been identified in the literature as influencing student performance. The study adopted a quasi-experimental design of pre-test, post-test and non-randomized control group. The study sample was 119 senior school students from two intact classrooms. Data were collected using the Genetic Achievement Test, and Group Embedded Figure Test.Data collected was analyzed using descriptive and inferential statistics, hypotheses were tested using ANCOVA at0.05 level of significance. The results of the study revealed that students exposed to MIS performed better than their counterparts in the control group. It was also revealed that there was no significant difference between the results of the students according to their cognitive styles. Therefore, it was recommended that teachers could adopt the use of MIS in teaching genetics and other hard-to-teach biological concepts.
Veterinary antimicrobial prescribing practices for treatment of presumptive sporadic urinary tract infections in dogs examined at primary care practices in the United States (2010–2019)
Authors: Bloch Rebecca A. , Papich Mark G. , Stürmer Til
Published: April 2022

OBJECTIVE

To describe patterns of antimicrobial prescriptions for sporadic urinary tract infections (UTIs) in dogs in the United States from 2010 through 2019, including times before and after publication of International Society for Companion Animal Infectious Disease (ISCAID) guidelines.

SAMPLE

461,244 qualifying visits for sporadic UTIs.

PROCEDURES

Veterinary electronic medical records of a private corporation consisting of > 1,000 clinics across the United States were examined to identify canine visits for potential sporadic UTI between January 1, 2010, and December 31, 2019. Proportions of antimicrobial prescriptions were graphed by month and year to identify changes in prescription patterns over time. Interrupted time series analysis was performed for the aminopenicillins.

RESULTS

A total of 461,244 qualifying visits were examined, with 389,949 (85%) of these resulting in at least 1 antimicrobial prescription. Over the 10-year period, the proportion of visits resulting in no antimicrobial prescription increased (14% in 2010 to 19.7% in 2019). Proportions of prescriptions for amoxicillin (38% to 48%) and amoxicillin–clavulanic acid (2.5% to 10%) also increased. Log-linear regression supported that changes in proportions of amoxicillin and amoxicillin–clavulanic acid prescriptions occurred following the 2011 ISCAID guidelines publication, with the proportion of amoxicillin prescriptions increasing by 13% per year (95% CI, 12% to 14%; P < 0.01) and the proportion of amoxicillin–clavulanic acid prescriptions increasing by 0.5% per year (95% CI, 0.2% to 0.8%; P < 0.01). Use of fluoroquinolones and third-generation cephalosporins remained constant.

CLINICAL RELEVANCE

Results suggest that efforts to guide antimicrobial use in veterinary clinical practice are having positive effects in this private veterinary company, though continued efforts are warranted.
Expression and biochemical significance of Piwil2 in stem cell lines
Authors: Kaan Dilek
Published: April 2022

Introduction

P-element induced wimpy testis-like 2 (Piwil2) is in the Piwi gene family. Piwil2 has important roles in the self-renewal mechanism of stem cell induction and progression of numerous types of human malignancies such as lung, breast, colon, prostate, and cervical cancers. Glutathione S-transferase (GST) acts as detoxification in cancer metabolism. This study aimed to investigate the effects of the stem cell protein Piwil2 on MCF10A and MCF-7 at the GST activity levels.

Materials/Methods

MCF-7/Piwil2 and MCF10A/Piwil2, transfected with a plasmid carrying the Piwil2 gene, and non-transfected MCF-7 and MCF10A were cultured in a complete DMEM/F12 medium. GST A1 and P1 activity was determined in these cell lines using as substrates CDNB, EA respectively.

Results

According to experimental results, GST P1 activity decreased in the MCF-7/Piwil2 cells as compared with the non-transfected MCF-7 cells, however, MCF-7/Piwil2 cells demonstrated increases in GST A1 (total GST) activity. The statistically significant differences were found for the comparison of non-transfected MCF-7 and MCF-7/Piwil2 (p<0,0001), for GST enzyme activities by using CDNB and EA as substrates. These results were the same for the MCF10A cell line.

Discussion

It is shown for the first time that transfection studies may affect GST activity at the cellular mechanism level. The study contributes to determining the effect of transfection on GST isoenzymes and also how the Piwil2 gene may affect GST activity in the stem cell line.

Identification of contractions from Electrohysterography for prediction of prolonged labor
Authors: Vasist Santosh N , Bhat Parvati , Ulman Shrutin , Hebbar Harishchandra
Published: April 2022

The analysis of the uterine electrical activity and its propagation patterns could potentially predict the risk of prolonged/arrested progress of labor. In our study, the Electrohysterography (EHG) signals of 83 participants in labor at around 3-4 cm of cervical dilatation, were recorded for about 30 minutes each. These signals were analyzed for predicting prolonged labor. Out of the 83 participants, 70 participants had normal progress of labor and delivered vaginally. The remaining 13 participants had prolonged/ arrested progress of labor and had to deliver through a cesarean section. In this paper, we propose an algorithm to identify contractions from the acquired EHG signals based on the energy of the signals. The role of contraction consistency and fundal dominance was evaluated for impact on progress of the labor. As per our study, the correlation of contractions was higher in case of normal progress of labor. We also observed that the upper uterine segment was dominant in cases with prolonged/arrested progress of labor.
Advances in the application of regenerative medicine in prevention of post-endoscopic submucosal dissection for esophageal stenosis
Authors: Wang Jiaxin , Zhao Yan , Li Peng , Zhang Shutian
Published: April 2022

Endoscopic submucosal dissection (ESD) is a curative treatment for superficial esophageal cancer with distinct advantages. However, esophageal stenosis after ESD remains a tough problem, especially after large circumferential proportion of esophageal mucosa is removed, which limits the wide use of ESD, especially in circumferential lesions. In this scenario, preventive procedures are highly recommended against post-ESD esophageal stenosis. However, the efficacy and safety of traditional prophylactic methods (steroids, metal and biodegradable stents, balloon dilation, radial incision, etc.) are not satisfactory and novel strategies need to be developed. Regenerative medicine has been showing enormous potential in the reconstruction of organs including the esophagus. In this review, we aimed to describe the current status of regenerative medicine in prevention of post-ESD esophageal stenosis. Cell injection, cell sheet transplantation, and extracellular matrix implantation have been proved effective. However, numerous obstacles still exist and further studies are necessary.

Kualitas telur dapat menentukan fertilitas dan efisiensi reproduktif ayam.  Pemuliabiakan selektif ayam hibrida Kambro diduga mempengaruhi kualitas telur. Studi ini bertujuan untuk menentukan pengaruh pemuliabiakan selektif terhadap kualitas telur dua generasi ayam hibrida F1 Kambro (F1K)-biak silang dan F2 Kambro (F2K)-biak dalam. Nilai koefisien (F) dan laju biak-dalam (Fx) ayam F2K dihitung. Rekam data telur ayam dianalisis berdasarkan produktivitas, fenotipe, berat, indeks, dan parameter kualitas eksterior telur. Parameter kualitas eksterior telur dianalisis dengan formula matematis. Produktivitas telur dalam hen day production (HDP) ayam F1K dan F2K selama 270 hari secara berurutan yaitu 24% dan 16,5%. Heterosis pada F2K sebesar -31,25% menunjukkan terdapatnya tekanan biak-dalam terhadap produktivitas telur. Fenotipe telur ayam F2K terbagi empat yaitu light-brown, cream, brown, dan white. Rerata berat telur (EW) ayam F1K dan F­2K secara berurutan yaitu 53,34 ± 2,34-gram dan 54,92 ± 9,25-gram, maka tergolong ke dalam kategori small egg. Indeks bentuk telur ayam F1K dan F2K secara berurutan didominasi oleh sharp egg dan round egg. Parameter kualitas eksterior telur ayam F1K dan F2K berdasarkan GMD dapat digunakan sebagai variabel prediktor, sementara Sp (r = 1, p<0,001) tidak menggambarkan pengaruh pergeseran kurva regresi. Nilai Fx dan F ayam F2K secara berurutan yaitu 4,925% dan 25% tepat pada batas ambang toleransi biak-dalam inbred line. Tekanan biak-dalam berhubungan dengan depresi produktivitas dan karakter telur antara ayam F1K dan F2K. Pemilihan indukan pada pemuliabiakan selektif wajib memperhatikan faktor tekanan biak-dalam, nilai koefisien, lajunya, dan kualitas telur. Penerapan seleksi genomik berpeluang dalam meminimalisir pengaruh dan lonjakan nilai Fx dan F.

At the beginning of 2020, the world was shocked by the emergence of a virus that attacks humans and spreads very quickly between humans. This virus is known as the Covid-19 virus. Various efforts have been made, such as by urging the public to comply with health protocols. Over time, the handling of the Covid-19 virus in several countries was followed by efforts to restore economic and social aspects that were hampered, leading to policies taken by the government called the new normal. The existence of this new normal condition certainly causes a new change and adaptation. Changes in work behavior can occur due to the implementation of a number of new rules and the work environment. The design of this study was carried out using qualitative methods. The informants selected in this study were four informants who worked in Badung Regency. This study found that changes in employee work behavior in the new normal era included: (1) The work environment, changes from the Covid-19 virus related to work habits, while the impact of these changes led to additional things that must be paid more attention to, namely health protocols. (2) Communication between employees in this new normal era runs as usual and is fairly smooth. (3) The absence of serious conflicts during the implementation of the new normal era. Conflicts that arise are usually related to misunderstandings.

Contamination of heavy metals on agricultural soil can have an impact on the quality of agricultural crops. This study aimed to determine the effect of the addition of cow manure on the bioavailability of heavy metals, Cu and Pb in agricultural soil and the content of those metals in spinach plants produced from the soil. The metals contents were obtained through the sequential extraction and wet digestion methods, followed by the measurement of metal concentration using an AAS tool (Shimadzu A 7000). In this study, it was found that the metal content of Cu and Pb in spinach plants whose soil was given fertilizer of cow manure was lower than that of the soil without fertilizer. The average content of Cu and Pb in all parts of the spinach plant without fertilizer application was 53.5985 ± 0.3943 and 59.7982 ± 2.8389 mg/kg, while those given the fertilizer were 41.7626 ± 1.3590 and 52.4335 ± 0.8434 mg/kg, respectively. The level of Cu and Pb bioavailabilities also decreased with the addition of the fertilizer. The number of Cu and Pb metals being bioavailable have decreased, while the metals which were potentially bioavailable have increased significantly. Therefore, the application of cow manure as fertilizer to the agricultural soil could reduce the bioavailability of Cu and Pb metals, and their accumulation in spinach plants, as well.
