Authors: Ouyang Ping , Wang Chao , Wang Peifang , Gan Xiaorong , Wang Xun , Yang Chaohui
Published: June 2020

The inhibition of cyanobacteria growth by allelochemicals, which controls harmful algal blooms has been examined in many studies. The objective of this work was to compare the efficiencies of different allelochemicals and determine a mixing proportion corresponding to the highest algae inhibiting activity and smallest adverse effect. The obtained results demonstrated that artemisinin, nonanoic acid, malonic acid, and ethyl acetate inhibited algal growth more efficiently than D-menthol and lactic acid. Synergies were observed in five groups of allelochemical combinations with inhibition ratios exceeding 80%, and the concentrations of extracellular microcystin-LR in the groups with high algal inhibition ratios were lower than that in the control group on the 7th day. No changes in extracellular polymeric substances compositions were detected after treatment. The permanganate indices of the treated groups were higher than that of the control group; however, this disparity gradually decreased with time. In addition, a sharp decrease in the concentration of dissolved inorganic phosphorus was observed for all treated groups. From the obtained data, the optimal proportion of mixed allelochemicals corresponding to 3.94 mg L−1 of artemisinin, 6.27 mg L−1 of nonanoic acid, 8.2 mg L−1 of malonic acid, and 6.38 mg L−1 of ethyl acetate was suggested.
Comparative Study on Numerical Calculation of 2-D Random Sea Surface Based on Fractal Method and Monte Carlo Method
Authors: Wu Gengkun , Liu Chuanxi , Liang Yongquan
Published: June 2020

Based on fifty one groups of data on direction distribution measured from buoy sites, several important spectrum parameters including distribution characteristics of the measured data’s spectrum, the Wen’s direction spectrum and the Donelan function are analyzed from the perspectives of standard deviation of directional distribution function and statistical results. Then, a numeric calculation model based on the Monte Carlo method is proposed in this work. At the same time—based on Weierstrass self-affine fractal function—numeric simulation of random sea surface is conducted by modifying the bilateral power law. The analysis of the numeric calculation results under different wind directions, speeds and fetches proves that both methods can be adopted for different water directional distributions and target spectrum models. In addition, this study compares the characteristic wave within different distribution frequency domains in the main wave direction and in its orthogonal direction. It is proved that the fractal method cannot fully reflect the anisotropy of gravity wave and tension wave in the superposition direction, however, it can maintain the similarity of overall energy part with the rough length of the waves. Moreover, there are still limitations of the fractal method in the numeric modeling of undeveloped sea surface.

Published: June 2020

The impact of economic growth on natural resources and the environment constitutes a fundamental topic in current research. In particular, water, a fundamental resource for human beings, has been subject to intense pressure in recent decades. Within this context, this article examines the growth of the blue water footprint of the Spanish wine industry and its environmental impact. In order to do this, we will first calculate the blue water footprint of wine, using a bottom-up methodology. Our methodology introduces certain advances with respect to those usually used. Our results show a very fast increase of the blue water footprint from 1995, which has multiplied six-fold in twenty years with an extreme concentration in the region of Castilla-La Mancha, which accounts for 70% of this increase. The expansion of irrigated vine growing in this region has played a relevant role in the serious problems suffered by its aquifers.
Water and Energy Demand Management in Pressurized Irrigation Networks
Authors: Pardo Miguel Ángel , Riquelme Adrián J. , Jodar-Abellan Antonio , Melgarejo Joaquín
Published: June 2020

Minimizing energy expenditure is one of the main purposes of the managers of pressurized irrigation systems. From the energy consumption standpoint, they can reduce energy consumption by supplying a constant flow into the system (a scheme different from urban water pressurized networks in which water demands depend on users). Managers can keep energy demands (opening and closing valves) while meeting pressure restrictions. We developed a computer application in MATLAB containing a genetic algorithm to find the best moment to open and to close valves to minimize an objective function which measures the differences between the objective and the real injected flows. We tested this program in the pressurized irrigation network of the San Vicente Campus, University of Alicante (Southeast Spain) and we calculated the water and energy balance (from the later and present irrigation network) and the carbon credits not emitted to the atmosphere.
Thermodynamic model of cryogenic fuel tank processes

Published: June 2020

A new procedure is created for the calculation of heat and mass transfer processes in a cryogenic rocket tank. This simplified method is based on the assumption about homogeneity of temperature in liquid and vapor phase of a fuel component. This assumption made this model useful for such regime as refueling, self-pressurization, pressurization during engine working and other.
As the example of method applicability, some calculation is made for refueling of KVTK upper stage to estimate component losses. For the self-pressurization regime, the results of the calculation is compared with experimental data for one cylindrical and one spherical hydrogen tanks. This comparison is shown that pressure rise rate in a full tank several times upper than in the calculations. But for the low level of liquid hydrogen the accuracy of this method is significantly increased. As the result, this procedure is recommended as a lover score of pressure rise during self-pressurization.
Key words: cryogenic propellant tank, cryogenic fuel storage, cryogenic tank processes, mathematical modelling, calculation method, refueling, mass-average temperature.
Study of radial burning of holes in titanium shells of high-pressure tanks with oxygen containing gas
Authors: TUPITSYN Nikolay N.
Published: June 2020

The paper presents the results of the experimental study of radial burning of holes in titanium samples simulating a fragment of the shell of a high-pressure tank filled with gaseous oxygen or oxygen-containing gas. The tests revealed the possibility of a large increase in the orifice area (140–2 250 times compared with the initial value) as a result of the burning of small through-holes when oxygen-containing gas of the increased pressure flows through them and allowed us to determine the apparent radial burning rate at various oxygen concentrations.
The proposed mathematical dependence of the hole size in the titanium shell after their radial burning on the process parameters may be of interest for the analysis of processes occurring in engineering systems in case of some off-nominal and emergency situations.
Key words: radial burning of holes, titanium tank, oxygen-containing gas, off-nominal and emergency situations.

A phenomenon (failure) is considered as the change of state of the system (structure) between the origin (hazard threshold) and the destination (failure) points. The survive and the lost ratios of the system characteristics (stiffness) are defined in this paper in terms of stiffness, and the survive and failure (phenomenon) functions. The phenomenon functions are defined (in turn) in terms of the system identification parameter (state variable) and two control parameters. These parameters were calibrated by mapping them on four selected key points including origin, quarter point, middle point and end points in the system behaviour space. The failure function was used as fragility function. The validity of the work was verified by comparing the results with the fragility curves of four nuclear power plant containment vessels.

Published: June 2020

Keberadaan Undang-Undang Negara Republik Indonesia Nomor 5 Tahun 2014 tentang Aparatur Sipil Negara berbeda dengan undang-undang kepegawaian sebelumnya. Perbedaan tersebut terletak pada adanya pegawai pemerintahan lain selain PNS, yaitu Pegawai Pemerintah dengan Perjanjian Kerja (PPPK). Apabila kita kaitkan dengan bentuk pengangkatan PPPK adalah dengan perjanjian kerja untuk waktu tertentu, maka secara tersirat kedudukan PPPK adalah pegawai pemerintah yang memiliki kekuatan hukum pada perjanjian kerja. Perjanjian kerja bagi PPPK merupakan pengikat hubungan hukum antara pegawai pemerintahan Non-PNS dengan instansi pemerintah yang mempekerjakannya. Perjanjian kerja tersebut berakibat hukum lahirnya hubungan hukum keperdataan. Mengikatnya hubungan hukum keperdataan ditunjukkan melalui kesepakatan kedua pihak untuk mengikatkan diri dalam suatu perjanjian berimplikasi terhadap perlindungan hukum hak-hak pekerja. Perlindungan hukum sebagai suatu gambaran dari fungsi hukum, yaitu konsep dimana hukum dapat memberikan suatu keadilan, ketertiban, kepastian, kemanfaatan dan kedamaian. Mengingat pentingnya hal-hal tersebut diatas, Penulis mengkaji dengan metode yuridis normative tentang pelaksanaan pengangkatan PPPK berdasarkan Undang-Undang ASN dan pengangkatan PPPK yang memberikan perlindungan hukum bagi calon pegawai pemerintah di institusi perguruan tinggi. Analisa permasalahan dikaitkan dengan asas-asas umum pemerintahan yang baik, sehingga dapat menggambarkan tentang pelaksanaan pengangkatan PPPK di institusi perguruan tinggi dapat memberikan perlindungan hukum.

Abstrak Penelitian ini mengungkap asal mula sumber hukum Islam selain dari yang baku (Alquran dan hadis) yang belakangan ini menjadi perdebatan sangat serius antara ulama tradisional dan revisionis Barat, antara keduanya bersikeras mempertahankan pendapatnya masing-masing. Penelitian ini menggunakan metode kualitatif yaitu dengan cara menelusuri sumber-sumber tertulis yang berkaitan dengan permasalahan tersebut. Pemikiran Yasin Dutton mengenai asal mula sumber hukum Islam sebagaimana yang dituliskan oleh Imam Malik dalam kitab al-Muwatta’-nya, tidak hanya bersumber pada Alquran dan Hadis yang diperdebatkan oleh kedua kubu di atas. Akan tetapi, di samping itu ada ‘amal atau tradisi masyarakat Madinah yang bisa dijadikan sebagai sumber hukum Islam. Karena Madinah pada waktu itu merupakan sumber ilmu pengetahuan Islam dan juga Madinah sebagai tempat di mana para tabi’in yang banyak berguru kepada sahabat Nabi Muhammad saw. Meskipun demikian, posisi Alquran tetap menempati sumber utama yang dijadikan sebagai sumber hukum Islam dan Alquran sendiri menjadi motor bagi sunnah Nabi. Kata Kunci: Al-Muwatta’, Imam Malik, Yasin Dutton

AbstrakPenelitian ini bertujuan mengurai konsep dan muasal teori al-s}arfah, perbedaan padangangan para ulama terkait teori al-s}arfah serta perkembangan teori al-s}arfah dalam kajian kemukjizatan al-Qur’an kontemporer. Penelitian ini merupakan penelitian pustaka (library research), dengan cara mengumpulkan literatur terkait kemudian disajikan secara deskriptif kualitatif, yaitu menampilkan data sebagaimana adanya kemudian dianalisis (content analysis). Teori al-s}arfah merupakan konsep dalam kemukjizatan al-Qur’an yang menyatakan bahwa ketidakmampuan manusia menandingi al-Qur’an karena Allah swt. mencegah manusia untuk menandinginya dengan mencabut kemampuan, motivasi, ilmu, serta pengetahuan manusia untuk menandingi al-Qur’an. Terdapat dua pendapat mengenai muasal teori al-s}arfah. Pertama, teori ini berasal dari konsep yang ada di dalam Agama Hindu, sedangkan pendapat kedua memandang, al-s}arfah berasal dari pemikiran Islam yang disebabkan kesalahpahaman terhadap al-Qur’an disertai akidah yang salah. Tokoh yang dianggap pertama kali melontarkan teori al-s}arfah adalah tokoh Muktazilah, Abu Ish}aq Ibrahim al-Naz}z}am. Ulama berbeda pendapat terkait teori al-s}arfah dalam kemukjizatan al-Qur’an, pada umunya ulama yang pro terhadap teori ini dari kalangan Muktzilah dan Syi’ah. Sementara, yang kontra dari kalangan Sunni.  Di era kontemporer ini, diskursus kemukjizatan al-Qur’an makin berkembang dan mencakup berbagai aspek, tidak seperti dahulu yang masih didominasi pada aspek kebahasaan. Sementara teori al-s}arfah hanya berlaku pada aspek kebasahaan dan sistematika susunan al-Qur’an, sehingga teori ini tidak relevan dalam konteks kemukjizatan al-Qur’an kontemporer yang cenderung mengungkap isyarat ilmiah dari al-Qur’an.Kata Kunci: Al-S}arfah, Kemukjizatan, al-Qur’an, Muktazilah.

Fryums, a popular Indian snack item prepared using white rice (Oryza sativa) as a main ingredient, was used as a base for developing black rice fryums. In this study, the white rice was replaced by Burma black rice (Oryza sativa) to the extent of 50 per cent (variation one), 75 per cent (variation two) and 100 per cent (variation three). Sensory evaluation of the three variations was done using 9 point hedonic scale and food action rating scale (FACT). One way ANOVA and Least Significant Difference (LSD) post hoc test were used to analyse the results. Variation one and two which used a combination of white rice and black rice received low sensory scores compared to variation three. The difference in amylose and amylopectin ratio of white rice and black rice which directly influences the cooking properties of rice may be responsible for this. Variation three was found to be closest to the basic recipe in terms of sensory properties. The sun dried hundred per cent Black rice fryums provide 290.5 kcals of energy, 72.25 g of carbohydrates and 8.71 g of protein per 100 g. The evaluation by Food Action Rating Scale, revealed that it was overall acceptable. There are hardly any studies on black rice fryums. This study is an attempt to extend the benefits of the black rice, which is known to have many functional properties, to the non consumers of black rice and to add variety to the diets of black rice consumers.

A field experiment was conducted at Tamil Nadu Rice Research Institute, Aduthurai to assess the land use efficiency and productivity of rice under intercropping system. Treatments consisted of six irrigation regimes viz., IW (depth of irrigation water) / CPE (Cumulative pan evaporation) ratio 1 up to harvest, IW/CPE 0.75 up to 60 days thereafter IW/CPE 1, IW/CPE 0.75 up to 60 days thereafter IW/CPE 1.25, IW/CPE 0.75 up to 60 days thereafter IW/CPE 1.50, IW/CPE 1 up to 60 days thereafter IW/CPE 1.25 and IW/CPE 1 up to 60 days thereafter IW/CPE 1.50 and three cropping system viz., Rice alone, Rice + Blackgram and Rice + Greengram. Results revealed that application of irrigation water at different levels and cropping systems markedly influenced the growth, yield components and yield of rice. The maximum value of growth and yield components were recorded with the application of irrigation IW/CPE ratio of 1 up to 60 days thereafter IW/CPE ratio of 1.50 and among the cropping systems aerobic rice alone showed significantly higher growth and yield. Water productivity is higher in irrigation with IW/CPE ratio of 1 up to 60 days thereafter 1.50. The land equivalent ratio (LER) also revealed both the intercropping systems were advantageous. The results encourage the options of pulses could be grown as inter crop in rice.

Essential plant nutrient elements are generally applied to crops through soil to achieve more economic yields. Of the methods followed soil application is common and efficient for nutrients required in large quantities. However, under some situations crop responds better to foliar application along with blanket doses of fertilizers. Foliar application of urea phosphate (UP), an acidic nitrogen (N) and phosphate (P) nutrient fertilizers, along with blanket fertilizer doses can influence the yield as well as nutrient uptake and grain quality characteristics of the crop rice. A field experiment was conducted to study the impact of urea phosphate on yield, nutrient uptake and grain quality of rice (Oryza sativa L.) in acid Inceptisols of Odisha, India. Different treatments were thus framed to test the hypothesis as T1-control (no nutrient); T2- 50% recommended dose of fertilizer (RDF); T3 -75% RDF; T4 -100% RDF; T5 -50% RDF + twice foliar spray (FS) of 1% UP; T6 -50% RDF + twice FS of 2% UP; T7 -75% RDF + twice FS of 1% UP; T8 -75% RDF + twice FS of 2% UP; T9 -100% RDF + twice FS of 1% UP and T10 -100% RDF + twice FS of 2% UP. Growth parameters like plant height (107.60 cm), panicle length (25.72 cm) and number of effective tillers per hill (13.58) were found to be highest in the plots where twice FS of 2% UP along with 100% RDF was applied. The grain (4579.33 kg ha-1) and straw yield (5121.90 kg ha-1) of rice were also observed highest with T10 over T9, where 100% RDF + twice FS of 1% UP was applied. Uptake of nutrients like N (63.45 kg ha-1), P (18.36 kg ha-1 ) and K (96.85 kg ha-1) were found to be numerically higher in T10 where 100% RDF + twice FS of 2% UP was applied. The grain quality parameters of rice like protein content (R² = 0.624), alkali value (R² = 0.622) and amylose content (R² = 0.618) were significantly varied among the treatments.

A field experiment was conducted at the Agricultural College farm, Bapatla, during kharif and rabi 2017-18 and 2018-19. The experiment was conducted with variety BPT-5204 in a randomized block design with ten treatments and three replications. The maximum Number of panicles m-2, total filled grains panicle-1, test weight, grain yield, straw yield, harvest Index and return per rupee investment were recorded with soil test based fertilizer recommendation with 10 t ha-1 FYM application which was at par with soil test based fertilizer recommendation alone and 7.5 t ha-1 targeted yield recommendation along with FYM (T5 and T10) and RDF with FYM (T6). Grain yield of rice was significantly higher with soil test based fertilizer recommendation with 10 t ha-1 FYM application which was statistically at par with soil test based fertilizer recommendation alone (T2) and 7.5 t ha-1 targeted yield fertilizer recommendation with FYM (T10) compared to the rest of the treatments.
Strategi Pemerintahan Erdogan dalam Menghadapi Ancaman Politik dan Militer Suku Kurdi 2015-2019
Authors: Nabiyyin M. Hafizh
Published: June 2020

Pada tahun 2015, konflik antara pemerintah Turki dengan suku Kurdi –  terutama yang tergabung dalam Partai Pekerja Kurdistan (PKK)– kembali mengalami eskalasi. Eskalasi konflik antara kedua belah pihak ini terjadi akibat pelarangan terhadap militan-militan PKK yang berbasis di Turki untuk membantu mempertahankan Kota Kobane di Suriah –yang merupakan kawasan Kurdi Suriah– dari serbuan pasukan ISIS. Sebagai konsekuensi, kota-kota di Turki menjadi target serangan sporadis yang dilakukan oleh milisi PKK. Semangat kemerdekaan dan membentuk teritori dengan pemerintahan sendiri dari Turki kembali mengemuka. Apabila dilihat dari perspektif keamanan Barry Buzan, hal ini merupakan bentuk ancaman militer dan ancaman politik terhadap kepada Turki. Oleh karena itu, tulisan ini bermaksud untuk mengelaborasi strategi-strategi yang diambil oleh pemerintah Turki dalam mengatasi ancaman-ancaman suku Kurdi dengan menggunakan teori Masyarakat Internasional. Penulis menyimpulkan bahwa pemerintah Turki mengambil beberapa kebijakan untuk mempertahankan integritas teritorial dan legitimasi kedaulatannya, yaitu: (1) menjalin kerja sama dengan aktor negara dan aktor non-negara; (2) melakukan operasi militer internal dan eksternal; dan (3) melakukan represi terhadap jurnalis dan politisi pro-Kurdi.

Background: The individual effects of nicotine and caffeine have been reported in previous studies but their combined effect on tooth movement needs to be elucidated. The objective of this study was to evaluate the combined effect of nicotine and caffeine on the magnitude of orthodontic tooth movement (OTM) in rats.

Material and Methods: This experimental study was conducted on Sprague-Dawley rats (Animal House and Pathology Laboratory; Post Graduate Medical Institute, Lahore) in the department of Orthodontics, de’Montmorency College of Dentistry, Lahore from 8th July 2014 to 8th January 2015. Forty male Sprague-Dawley rats were divided into four equal groups: Control group (CR), nicotine group (NT), caffeine group (CF) and combined nicotine and caffeine group (CNC). Closed coil nickel titanium (NiTi) spring was placed between incisor and maxillary molar. Nicotine group (NT) was treated by intraperitoneal injections of nicotine. Caffeine was given to caffeine group and Combined nicotine and caffeine group (CNC) was treated in the same way as individual nicotine and caffeine groups daily for 14 days. All the rats were sacrificed on 15th day. Magnitude of the orthodontic tooth movement was measured using digital Vernier caliper. Means and standard deviation were calculated for orthodontic tooth movement. One-way ANOVA was used to determine the mean difference in OTM. Post hoc Tukey test was used for multiple comparisons among the groups.

Results: The mean orthodontic tooth movement (OTM) was 0.32 mm ± 0.05 in control group, 0.56 mm ± 0.04 in nicotine group, 0.52 mm ± 0.034 in caffeine group and 0.8 mm ± 0.06 in combined NC group, respectively. The difference between mean OTM among the groups was statistically significant (P-value <0.001). The mean OTM in CNC group was significantly higher as compared to other groups (CR, NT, CF, NT) (P-value <0.001).

Conclusions: In rats, the combined use of nicotine and caffeine results in greater orthodontic tooth movement as compared to their individual use.
