Authors: Rasooli Samaneh , Yousefirad Mojtaba , Taghavi Lobat
Published: February 2021

With the growth of industry and the increasing consumption of chemicals, their entrance into water, soil and air results in the contamination of environment and consequently the danger that humans face, resulting from heavy metals, is felt more than ever before. Phytoremediation is an environmentally friendly method employing plants for removing pollutants from contaminated soils. The present study was carried out under greenhouse conditions using factorial experiment based on the randomized complete blocks design in three replications in order to analyze the phytoremediation ability of Vetiveria zizanioides and Medicago sativa in soils contaminated with selenium. Five-kilogram pots of Vetiveria zizanioides and Medicago sativa with 0, 10 and 20 mg/Kg selenium in the soil were treated. Sixty days after the treatments, the plants were harvested. The results showed that in both Vetiveria zizanioides and Medicago sativa the effect of selenium in all the studied traits was significant (P<0.01). In both plants, with an increase in the amount of selenium in the soil, the dry weights of the organs decreased and the concentration of selenium in different organs increased. At every level of soil contamination the concentration of selenium in the different organs of Vetiver were higher than alfalfa. Since the transfer and absorption factors in the root and aerial parts of Vetiver were greater than that of Medicago, Vetiver has great ability in absorption and transfer of selenium from soil to shoot in comparison with alfalfa and is a more suitable plant for phytoremediation.

Drilling operations, like any other industrial activity, at the end of the operation employed dumps waste, wastewater to the environment, and if there is no planning for treatment and their elimination, in long-term this can have adverse effects on the environment. Assessment and recognition of the effects of drilling fluids is an acceptable and logical method for making a suggestion to reduce the probable injuries and damages resulting from the disposal and the drilling to the environment. In addition, one of the most important factors in reducing the negative environmental effects of waste is correct management. So that sometimes the cost required for the removal of pollution or controlling emissions of waste significantly decreases with proper and innovative management, and all the waste caused by the washing of the reservoir, well reservoirs, adjacent area of pumps and equipment related to wells enter water run-off and after entering into the storage basin, the solid settles there and its liquid phase enters dewatering to do operations and water treatment units. Moreover, at a later stage to decide whether dewatering water is appropriate for dilution or making clay or not, depends on the results of rheological water mixture and drilling fluid (1). If the desired mixture had appropriate rheological properties after treatment, dewatering water can be used.  (According to the environmental standards of water reuse and wastewater returned in accordance with the agenda of the Technical Office of the Executive Vice President of Strategic Planning and Monitoring, suitable Dewatering Water is the one that does not make rheological change properties more than 50% in the of the fluid). In this study, a number of drilling machines will be used in defined projects to the amount of waste in order to make use of the standards and to improve the rheological properties of the fluid examine (Islamic Republic of Iran Iran's vice president of strategic planning and monitoring, the Office of Strategic Technical Assistance Administration, 2010).

The Theory Of Constraints: A Comparative assessment
Authors: Mikaeeli Ali Reza , Fahkravar Mostafa , Esfahani Meysam , Fadaei Salman , Karimi Ali
Published: February 2021

The worldwide economic reorganisation of the last decade has regularly been accompanied by appeals to concepts of lean manufacturing and flexible systems. These generally imply a scaling of productive and operating capacity to match demand and current throughput levels. The issue of how to manage scarce capacity has risen in priority both because of a constant search for greater efficiency and because of imbalances between the supply and demand of many resources. Multiple constraints have emerged throughout the Irish economy for individual firms, and for entire sectors. In “The Goal” Eli Goldratt reinvigorated traditional optimisation insights by presenting them in the repackaged form of the Theory of Constraints (Goldratt and Cox ,1993). This management best seller took the form of a thriller following the struggle of plant manager with 90 days to save his loss making operation from shutdown. In it Goldratt and Cox attack cost accounting as the “enemy number one of productivity” and instead called for a holistic process of ongoing improvement integrating techniques such as MRP, Just in Time and Statistical Process Control. This paper examines in detail the relative utility of the Theory of Constraints compared to traditional management accounting approaches to resource utilisation in aiding decisionmaking. It also considers the propagation and evolution of the Theory of Constraints and critically examines the response it has generated in the accounting and management literature. The continuing survival of cost accounting in the face of frequent assaults similar to Goldratt’s may in part be due to the ability of the discipline to adapt its practices to integrate the mandated improvements into practice and educational curricula. The paper reflects on the process by which new ideas are assimilated into the conventional management wisdom based on this example.

Listeria and Salmonella species are high risk for human through contaminated foods; these bacteria are psychrophilic and could grow at low temperature even at refrigerator. Fish and shrimp and other aquatic organisms are very good resources for these kinds of bacteria. These bacteria are known as food-borne bacteria because infected of human by foods. These bacteria have been isolated from fresh and processing aquatic foods in the most countries. In this research, two different organs including intestines and gills from each fish were prepared at sterile condition for isolation of salmonella and Listeria. Listeria was indentified according to FDA and also salmonella was characterized according to impedance method. From total examined 60 fish, 18 fish was contaminated to salmonella and 3 fish was contaminated to Listeria respectively. The frequency of Salmonella and Listeria in Mahshahr fish was 0.30 and 0.05 and in Hendijan fish contamination with salmonella was 0.05 and contamination with Listeria was not reported. S. paratyphi, S. typhimurium B and S. cholera-suis C were identified in Mahshahr fish, but in Hendijan, fish was characterized S. paratyphi and S. typhimurium B. L. murrayi was only isolated specie from Mahshahr fish. These two pathogenic bacteria have contaminated Khuzestan coastal zone through human resources, animal waste, waste water and chemical industries. Therefore people receive these kind bacteria through consumption of aquatic contaminated marine foods.

Published: February 2021

The most important feature of architecture at Islamic age has been regarded as strengthening the human history from plurality and unity that such architecture from the artistic dimension and world structure goes beyond the time and place.  Dome has been regarded as the major element in Islamic-Iranian architecture that there is no doubt on continuity and evolution of domical buildings since Sassanid age till current age. Mosques with Arabic or column design in Umayyad dynasty have been mentioned as the early styles in Islamic architecture. These mosques follow a square or rectangular map with walled garden and roofed nave. Since 7th century, domes have been the major element in Islamic architecture. By the passage of time, dimensions of domes at mosque developed, occupied a small part of the ceiling in proximity of Mihrab to the entire ceiling above nave. According to the existing texts, the oldest dome which is referred relates to Parthian and early Sassanid era. This dome has been built in Firuzabad to the dimension of 10.16 meter and evolved at Sassanid age, after which construction of domes is exploited as a general pattern. Domical buildings in west differ from domical buildings in Iran.  Interesting difference lies on transfer of dome from cylindrical buildings to square buildings in Iranian architecture. Creation of dome and formation of hollow spaces have raised creation of spiritual spaces together with sense of comfort, under which the most important phenomenon of Islamic-Iranian architecture, holy shrines and sacred places have raised. In this research, firstly we will reach to a model of construction of main dome by overview of literature at architecture of domical buildings pre Islam in Iran and formation of them with an emphasis on domical buildings especially at Firuzabad, Fars and Bishapur, then we will review the domical buildings at Islamic age especially mosques and scared places, ultimately the evolution stages of dome design is examined in Islamic-Iranian architecture.

Nowadays, organizations conduct change projects based on reengineering processes because business processes reengineering (BPR) methodologies implement process-oriented approach. By this view governmental organizational also utilizes such methodology. One of the main practical issues of such implementation is about using BPR methodology in relief organization. On the other hand, Iran has been faced with an increase of accidents in various forms. Thus having more efficiency in relief agencies to deal with these accidents and maintain readiness in the face of threats is essential. Relief agencies should be covered by the Unexpected Disasters Center in order to carry out their missions and duties perfectly. Therefore, familiarity with the tasks of each group is inevitable. Given the foregoing, the main objective of this study is to investigate how we can develop a reengineering project based on BPR approaches in Iran relief agencies. By this we propose a new model for reengineering which has the main capabilities of general models in BPR methodology. In addition, we show the prerequisites of implementing new model in Iran Unexpected Disasters Center.

Namun, dalam implementasinya ternyata tampak belum efektif dan masih banyak ditemui pelanggaran. Hal ini terbukti dengan masih banyaknya ditemukan keramaian di tempat-tempat umum di Surabaya. Keinginan masyarakat yang membutuhkan kebijakan dan tindakan yang pasti oleh pemerintah menjadi salah satu penyebab ketidakpatuhan masyarakat terhadap kebijakan PSBB karena pemerintah dianggap kurang serius dalam mengangani pandemik saat ini. Artikel ini bertujuan untuk mengkaji, membahas dan menganalisa efektifitas peraturan perundang-undangan yang ideal dan mengidentifikasi peran pemerintah pusat maupun daerah guna memutus mata rantai penyebaran Covid 19 melalui kebijakan PSBB di Kota Surabaya.
ENHANCEMENT OF MECHANICAL PROPERTIES OF UHMWPE POLYMER BY NITROGEN ION IMPLANTATION
Authors: Kishore N Venkat , M Nagendra , Rao T Venkateswara
Published: February 2021

The use of ion implantation as a surface treatment technology has been conquered by its applications to prevent wear and oxidation in metal alloys, even though some early works already pointed out that ion implantation could also be effective as a surface treatment for other materials, including polymers. Further research has shown that low dose implantation of energetic light ions could be very effective for improving properties such as wear resistance and hardness in many different polymers. Cross linking of polymeric chains due to ionization energy provided by the stopping process is the main mechanism to explain the changes in mechanical properties. According
to this model the lighter the ion is, the stronger is the effect. This thesis presents the results obtained by nitrogen implantation in ultra-high molecular weight polyethylene (UHMWPE). N+ ions were implanted at 80 keV, 100 keV and 120 keV energy levels which are maintained at a fluencies or dose of 5×1015 ions/cm2 . Wear resistance was measured using pin-on-disc wear testing machine at a constant load of 18 kg or 177N with a sliding speed of 2 m/s for about 1000m sliding distance. The results clearly show a lower weight and volume loses for samples implanted with nitrogen, in comparison to those implanted with untreated samples. Hence from the results of weight and volume
loses of the treated or implanted samples with nitrogen ion, gives very good wear resistance than untreated samples.

Perbandingan Hukum terkait Pembentukan Pasal Penghinaan terhadap Peradilan, Perzinahan, dan Santet dalam RKUHP Indonesia
Authors: Fitrah Farrel Alanda
Published: February 2021

Penelitian ini bertujuan untuk menganalisis aspek perbandingan hukum terkait pembentukan pasal penghinaan terhadap peradilan, perzinahan, dan santet dalam RKUHP Indonesia. Penelitian ini menggunakan metode penelitian yuridis normatif dengan spesifikasi bersifat deskriptif. Adapun metode analisis yang digunakan dalam penelitian ini adalah analisis perbandingan hukum. Perbandingan hukum dilakukan untuk mengetahui persamaan dan perbedaan unsur dari setiap sistem hukum, sehingga dapat menjadi alternatif dalam menyikapi persoalan-persoalan tertentu. Hasil penelitian menunjukkan bahwa Indonesia menganut civil law system sebagai warisan dari Belanda. Akan tetapi, tidak ada lagi negara yang murni menganut civil law system atau common law system. Perpaduan antara civil law system dan common law system di Indonesia disertai pula dengan perpaduan antara unsur hukum agama dan hukum adat. Hal ini dapat diketahui dari aspek perbandingan hukum terkait pembentukan pasal penghinaan terhadap peradilan, perzinahan, dan santet dalam RKUHP Indonesia. Tindak pidana penghinaan terhadap peradilan atau contempt of court dirumuskan dalam Pasal 302-325 RKUHP, dimana muatan dari Pasal tersebut merupakan perpaduan dari common law system. Tindak pidana perzinahan dirumuskan dalam Pasal 418 RKUHP, dimana muatan dari Pasal tersebut merupakan perpaduan dari hukum agama yang ditransformasikan ke dalam sistem hukum Indonesia yang menganut civil law system. Tindak pidana delik santet dirumuskan dalam Pasal 252 RKUHP, dimana muatan dari Pasal tersebut merupakan perpaduan antara sistem hukum adat dengan sistem hukum agama yang berusaha diterapkan ke dalam sistem hukum Indonesia. Olehnya itu, disarankan agar peran perbandingan hukum dalam menelaah proses pembaharuan hukum harus terus dilakukan, sehingga sistem hukum di Indonesia terus bergerak ke arah yang lebih baik.

Komunikasi non verbal menjadi bahasa yang sering digunakan dalam menyampaikan pesan  atau informasi. Publik memahami bahwa bahasa verbal tidak selalu dapat mewakili maksud dan tujuan si pemberi informasi. Bahasa tubuh membantu khalayak dalam memahami ekspresi yang tidak diucapkan. Bahasa non verbal dapat berupa kinesik atau gerakan tubuh, sentuhan,  intonasi suara, gerakan mata, sikap diam dan postur tubuh. Bahasa tubuh dirasa amat penting eksistensinya dalam setiap aspek kehidupan, termasuk di bidang politik. Komunikator politik menggunakan bahasa tubuh untuk menyampaikan pesan melalui saluran-saluran tertentu untuk mempengaruhi target politiknya. Aktor politik dapat mempengaruhi khalayak dengan pesan- pesan politik yang persuasif sekaligus memberikan pencitraan yang baik melalui bahasa tubuh yang positif. Karenanya gerakan tubuh, kontak mata dan fisik, irama suara, bahkan bentuk  tubuh dapat mempengaruhi konstituen untuk percaya dan akhirnya menjatuhkan pilihan terhadap kandidattertentu.

Kondisi remaja saat ini sangat memprihatinkan, degradasi moral seperti tawuran pelajar, seks bebas, aborsi, narkoba dan lain sebagainya seakan menjadi suguhan sehari-hari. Salah satu upaya yang dilakukan oleh para pakar pendidikan untuk menangani permasalahan tersebut adalah dengan pendidikan berkarakter. Pendidikan berkarakter adalah Pendidikan untuk pembangunan karakter yang mencakup pengembangan substansi, proses dan suasana atau lingkungan yang menggugah, mendorong, dan memudahkan seseorang untuk mengembangkan kebiasaan baik dalam kehidupan sehari-hari. Agar terwujud pendidikan yang berkarakter maka peran negara sangatlah penting. Kebijakan- kebijakan yang di terapkan oleh Negara haruslah mendukung pembentukkan karakter yang baik pada remaja. Akan tetapi pada kenyataannya dalam sistem demokrasi sekuler kebijakan-kebijakan yang diambil sarat dengan berbagai kepentingan. Beberapa kebijakan yang tidak mendukung pembentukkan karakter antara lain; dalam menyikapi tawuran remaja diatur dalam Pasal 170 KUHP. Pasal ini mengandung kendala dan kontroversial tanpa memberikan efek jera. UU No 8/1992 tentang Perfilman, UU No 36/1999 tentang Telekomunikasi, UU No 40/1999 tentang Pers dan UU No 32/2002 tentang Penyiaran, yang mempermudah praktik seks bebas pada remaja dan RUU Kesetaraan dan Keadilan Gender (KKG) yang mempermudah praktik aborsi. Dan semua itu akan membuat pendidikan karakter di Indonesia hanya pada tataran teori dan sulit dalampengaplikasiannya.
