Authors: Hayder A. Naser  , Aseel I. Mahmood  , Sawsan K. Fandi  
Published: April 2021

In this work, linear and nonlinear optical properties of two types of Iraqi heavy crude oil extracted from fields in southern Iraq were determined. The nonlinear optical properties were measured utilizing Z-scan technology with He-Ne laser at 632.8 nm. It was found that nonlinear refractive index (NLR) values for the Basra and Kut heavy crude oil samples are 6.34381×10-4 and 8.25108×10-4 cm2/mW, respectively, while those for the nonlinear absorption coefficient (NLA) are 2.68942×10-5 and 2.58874×10-5 , respectively. These results showed that the two samples with linear and nonlinear optical properties can be used in optics field applications as optical limiter devices at a wavelength of 632.8 nm.
Dielectric Study of PVC-LiF Composites Films
Authors: Ahmad A. Hasan  
Published: April 2021

PVC-LiF composites films with different lithium fluoride (LiF) concentrations (0, 30, 50, and 70 weight %) were prepared by using the casting method. This research deals with the investigation of dielectric properties for PVC-LiF composite films as a function of frequency and temperature in the ranges of 100 to 107 Hz and 293 - 370 K, respectively. The A.C activation energy values estimated from Arrhenius equation were 0.03820, 0.3174, 0.2009, and 0.1845 eV for the different PVC-LiF films with different LiF concentrations, respectively. It was found that the activation energy decreases by increasing LiF concentration and frequency. The exponent (s) showed a progressive increase with LiF for PVC-LiF films, while it showed a non-systematic sequence with the increase of temperature. The dependence of the dielectric constant (εr) and dielectric loss (εi) on temperature and frequency was investigated for PVC-LiF films with the different LiF concentrations. The dielectric spectrum showed a strong dispersion when LiF was added to the polymer matrix (PVC) in the whole range of frequency and temperature. The results were interpreted in terms of structural differences caused by the effect of thermal treatment.

Published: April 2021

This study investigates load frequency control based generalized extended state observer (GESO) for interconnected power systems subject to multi-kind of the power plant. First, the mathematical model of the interconnected power system is proposed based on the dynamic model of thermal power plant with reheat turbine and hydropower plant. Second, the GESO is designed to estimate the system states and disturbances. In addition, the problem of unmeasurable system states in the interconnected power network due to lack of sensor has been solved by using the proposed load frequency control based GESO. The numerical experiments are carried out by using MATLAB/ SIMULINK simulation. The simulation results point out that the proposed control approach has the capacity to handle the uncertainties and disturbances in the interconnected power system with better transient performances in comparison with the existing control approach. The relevant dynamic models have already been used for the simulation of the physical constraints of the governor dead band (GDB) and generation rate constraint (GRC) effect in the power plants. It is evident that the robustness of the suggested controller in terms of stability and effectiveness of the system.

Published: April 2021

Studi ini bertujuan untuk mengetahui determinan pengangguran terbuka di Daerah Istimewa Yogyakarta. Penelitian ini menggunakan data sekunder yang diterbitkan oleh Badan Pusat Statistik tahun 2010-2018. Data tersebut mencakup tingkat pengangguran terbuka, pertumbuhan ekonomi, upah minimum kabupaten/kota, dan modal manusia. Penelitian ini menggunakan regresi panel berdasarkan Fully Modified Ordinary Least Square (FMOLS) dan Dynamic Ordinary Least Square (DOLS). Hasil penelitian menunjukkan bahwa pertumbuhan ekonomi berdampak negatif, sedangkan upah minimum kabupaten/kota berdampak positif terhadap pengangguran terbuka. Peningkatan pertumbuhan ekonomi mendorong penurunan pengangguran terbuka, sedangkan kenaikan upah minimum kabupaten diikuti oleh kenaikan tingkat pengangguran terbuka. Sementara itu, modal manusia tidak berpengaruh pada tingkat pengangguran terbuka akibat rendahnya rata-rata lama sekolah. Untuk itu, pemerintah perlu meningkatkan sumber daya manusia melalui wajib belajar 12 tahun.
Rotator Cuff–Related Shoulder Pain: Is It Time to Reframe the Advice, “You Need to Strengthen Your Shoulder”?
Authors: Powell Jared K. , Lewis Jeremy S. 
Published: April 2021

Synopsis Progressive resistance exercise, in isolation or in combination with other noninvasive therapies such as therapeutic touch, is the first-line approach to managing nontraumatic rotator cuff–related shoulder pain (RCRSP). Resistance exercise may be effective for people with RCRSP secondary to improving mechanical features of the shoulder, including strength, kinematics, and muscle timing and activation. However, strength gains are often small and clinically unimportant when measured during clinical trials. In this Viewpoint, we argue that clinicians should (1) continue to prescribe resistance exercise when managing RCRSP, and (2) embrace the broad biological mechanisms underpinning the efficacy of resistance exercise. Any benefit is governed by more than simple mechanical changes. The clinical message must go beyond the idea that the patient's weak, deconditioned, or frail shoulder is the basis of his or her pain, and all the patient needs to do is to get strong.

Published: April 2021

The purpose of this work was to determine the C. albicans protein concentration at the subcutaneous introduction. The therapeutic effect of C. albicans proteins has been studied in white mice. Animals were injected intraperitoneally with a suspension of C. albicans fungus. After five days and repeatedly, after 14 days, mice were infected subcutaneously with proteins of Candida cells of volume 0.2 mL. Fourteen days after each injection, the determination of the protective functions of the animal body has been carried out by the titer of specific C. albicans antibodies. According to the data obtained during studies on the treatment of candidiasis, it was found that in the subcutaneous administration after the first and second injection with a concentration of low molecular weight fraction of the C. albicans protein of 1, 2, 3, 4, and 5 mg/mL antibodies titers have doubled, indicating a lack of activation of the body's protective functions. Proteins of low molecular weight fraction of C. albicans with concentrations 1, 2, 3, 4, and 5 mg/mL do not activate the body's defence mechanisms.

Sosiologi Spiritualitas & Kesalehan Sosial
Authors: Romadhon Sukron 
Published: April 2021

Spirituality and a new religious awakening, are seen by religious elites as a stage of religious directness in carrying out religious traditions and rituals. New civilizations can instead be a threat to conventional religious traditions and rituals. Without the willingness of religious elites to criticize and re-interpret conventional ritual traditions and patterns, the functions of the world's major religions could fade. The world's major religions are increasingly alienated from the objective world and awareness of the lives of the people and their people. It seems that there will be a new form of religion or a new religion that is completely different from the tradition of religious rituals that have been carried out by the major religions of the world. While the religious elite is still attached to classical religious interpretations. But on the other hand, the emergence of modern society, encouraging the argument of secularization is part of modernization. The values underlying socio-political and economic relations also appear to be beginning to enter an irregular stage, when viewed conventionally, the spiritulitas of global civilization, rather than lies in the format of values, traditional systems and structures or modern rationality. New civilizations in social systems and Science and Technology (SCIENCE AND TECHNOLOGY) began to be directed at a more intuitive spirituality stage. Then came the act of social piety that proved impartiality over the duafa wal mustad'afin, workers and the poor who were oppressed by the economic system. The emergence of the term left theology only wants to explain about righteousness and belief based on the ability to perform acts of liberation of the proletariat. This action is not only done after the reality of the proletariat appears, but creates a social and economic system that has impartiality towards the proletariat.
PENGARUH INFLASI TERHADAP PROFITABILITAS BANK
Authors: Insyiroh Ika Insyiroh 
Published: April 2021

Inflation is defined as the general price trend. The tendency here is that the rise is not a momentary one. High inflation and uncontrollable rate can disrupt banking efforts in mobilizing public funds. This is because the high inflation rate causes the real interest rate to decrease. Such facts will reduce the public's desire to save so that the growth of banking funds sourced from thecommunity will decline. This study aims to determine the effect of inflation on the profitability of Bank Syariah period 2012-2014. The results of this study indicate that inflation has no significant effect on the profitability of Sharia Banks in the period 2012-2014. It can be seen from the hypothesis test where tcount is smaller than ttable and Sig> 0,05. No significant effect is because Islamic banks are not obliged to pay returns in a fixed amount, but based on the percentage of profits earned. Also supported by the correlation value of 0.161 which means the relationship can be ignored. The coefficient of determination between inflation onROA with a value of 2.6%. The rest, profitability is influenced by other factors namely CAR, Operational Efficiency, FDR, NPF and Exchange Rate (Exchange Rate)

Abstrak
Inflasi didefinisikan sebagai kecenderungan kenaikan harga secara umum. Kecenderungan yang dimaksudkan disini adalah bahwa kenaikan tersebut bukan terjadi sesaat. Laju inflasi yang tinggi dan tidak terkendali dapat mengganggu upaya perbankan dalam mengerahkan dana masyarakat. Hal ini disebabkan karena tingkat inflasi yang tinggi menyebabkan tingkat suku bunga riil menjadi menurun. Fakta demikian akan mengurangi hasrat masyarakat untuk menabung sehingga pertumbuhan dana perbankan yang bersumber dari masyarakat akan menurun.Penelitian ini bertujuan untuk mengetahui pengaruh inflasi terhadap profitabilitas Bank Syariah periode 2012–2014. Hasil penelitian ini menunjukkan bahwa inflasi berpengaruh tidak signifikan terhadap profitabilitas BNI Syariah pada periode2012-2014. Hal tersebut terlihat dari uji hipotesis dimana thitung lebih kecil dari tabel dan Sig > 0,05. Tidak signifikan pengaruh tersebut karena bank syariah tidak berkewajiban membayar return dalam jumlah tetap, melainkan berdasarkan prosentase dari keuntungan yang didapatkan. Selain itu didukung oleh nilai korelasi sebesar 0,161 yang artinya hubungan dapat diabaikan. Adapun koefisien determinasi antara inflasi terhadap ROA dengan nilai sebesar 2,6 %. Sisanya, profitabilitas dipengaruhi oleh faktor lain yaitu CAR, Efisiensi Operasional, FDR dan NPF dan Exchange Rate (Nilai Tukar).Kata Kunci : Inflasi, Profitabilitas, Bank Syariah.
