Authors: Muthipeedika Nibin Joy , Yadav D Bodke  , Sandeep Telkar  , Vasily A Bakulev  
Published: January 2020

A series of coumarin derivatives linked with 1,2,3-triazoles has been synthesized by utilizing the copper catalyzed azide-alkyne cycloaddition reaction and were screened for their antimicrobial and antioxidant properties. Some of the compounds displayed promising antibacterial activities (MIC ranging from 5-150 µg/mL) and moderate antifungal activities as compared to the respective standards. The compounds 4k and 4g displayed good antibacterial activity when compared with the standard, Ciprofloxacin, and 4n exhibited better antifungal activity when compared to other synthesized compounds. The in silico docking studies of the active compounds were carried out against the gyrase enzyme and from those studies, it was acknowledged that 4k possessed significant hydrogen bonding and hydrophobic interactions which could be the plausible reason for its superior activity as compared to the other synthesized compounds. The compounds 4h and 4q showed promising antioxidant activity when compared with the standard, BHT, which could be attributed to the presence of electron donating substituents.

Resumen. Una serie de derivados de cumarina enlazados con 1,2,3-triazoles fue sintetizada empleando la reacción de cicloadición azida-alquino catalizada con cobre y fue evaluada en sus propiedades antimicrobianas y antioxidantes. Algunos de los compuestos exhibieron actividad antimicrobiana promisoria (intervalo MIC de 5-150 µg/mL) y actividad antifúngica moderada con respecto a los estándares respectivos. Los compuestos 4g y 4k mostraron buena actividad antibacterial con relación al estándar. Fluconazole y 4n exhibieron mejor actividad antifúngica en comparación con el resto de los compuestos. Se llevaron a cabo estudios in silico de modelado molecular e interacción de los compuestos activos con la enzima girasa ADN. De estos estudios se observó que 4k posee enlaces puentes de hidrógeno e interacciones hidrofóbicas significativos, los cuales podrían ser una causa plausible de su actividad mayor a aquélla mostrada por los otros compuestos sintetizados. Los compuestos 4h y 4q mostraron una importante actividad antioxidante comparada con el estándar (BHT), lo cual podría atribuirse a la presencia de sustituyentes electro-donadores

Penelitian ini adalah penelitian lapangan dengan menggunakan study perbandingan. Sedangkan, tujuan desain penelitian adalah untuk membandingkan, meringkaskan berbagai kondisi, fenomena realitas sosial yang ada di masyarakat yang menjadi obyek penelitian, dan berupaya menarik realitas atau kenyataan yang sebenarnya mengenai bagaimana pelaksanaan perkawinan poligami yang terjadisekarang ini khususnya di Kec. Mare.Hasil penelitian menunjukkan. Poligami yang dipraktekkan di Kecamatan Mare Provinsi Sulawesi Selatan, adalah poligami (sirri) atau perkawinan yang tidak dicatatkan. Bila dipandang dari sisi agama sah karena pernikahannya dilakukan sesuai dengan tata cara pernikahan dalam Islam yaitu terpenuhinya rukun dan syarat sahnya pernikahan. Akan tetapi jika dipandang dari sisi undang-undang Negara pernikah mereka itu tidak sah karena tidak memenuhi syarat-syarat poligami dalam agama yang di syari’atkan oleh Allah swt. Faktor- faktor yang menyebabkan maraknya praktek poligami pada masyarakat Kecamatan Mare yaitu karena poligami bukan hal yang asing di lingkungan masyarakat desa mereka. Mereka tetap mempercayai bahwa poligami itu merupakan ajaran agama dan sunnah Nabi dan adanya anggapan masyarakat bahwa perkawinan tetap di pandang sah walaupun tidak dicatatkan. Yang penting sudah sesuai aturan agama. Dalam praktek poligami yang terjadi sekrang ini hanya semata-mata demi kepentingan pribadi tanpa melihat tujuan hakiki dari poligami itu sendiri, selain itu praktek poligami yang terjadi tidak memberikan sisi kebaikan atau kemeslahatan bagi pasangan yang melakukan poligami.

An experiment was conducted to study the application of alternative treatments to control postharvest fungal infection and shelf life extension of papaya under different maturity stages at the Laboratories of the Department of Horticulture and Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh during the period from August to October, 2018. The two factor experiment (maturity stages and postharvest treatments) was laid out in a completely randomized design (CRD) with three replications. Four postharvest treatments viz., control, hot water treatment (Fruits treated at 50±2ºC for 10 minutes), chitosan coating (2000ppm chitosan solution) and hot water+chitosan coating were assigned to papaya fruits which were maturity stage I or maturity stage II. Significant variations were observed between maturity stage I (green mature) and maturity stage II (0-10% yellowing of fruits) in relation to most of the parameters studied. Results showed that most of the parameters studied were significantly influenced by the afore-mentioned factors. Longer shelf life (12.64 days) was observed in maturity stage I fruits than maturity stage II fruits (12.18 days). Significant reduction in disease incidence and severity was noticed in the maturity stage I fruits as compared to maturity stage II fruits. The longest shelf life (15.20 days) was found in hot water treated and chitosan coated fruits of maturity stage I, whereas the shortest shelf life (8.52 days) was observed in control of maturity stage II fruits.

Authors: Bethe SS , Haque MN , Islam MR 
Published: January 2020

This study was aimed to determination of appropriate dosage of selected chemical admixtures to reduce water cement ratio for mortar mix also to determine its effects on physical and mechanical properties of cement mortar. Amount of water used in concrete is very important for the physical and mechanical properties. Less amount of water increase the strength but reduce the workability. Water retarding admixture can reduce the water cement ratio with desired workability. In this experiment plasticizer (master pel 707) and super plasticizer (master polyheed 8632) was used. The used dosages of admixture were 0.5%, 1% and 1.5% according to cement weight. The test was done at 3 days, 7 days, 28 days and 91 days. 2.76″ cube mold was used for the work. The experiment was done to find the difference between with and without admixture used in mortar. Water used reduced with add of plasticizer and super plasticizer. In the experiment the workability of normal mortar and admixture used mortar remain same. The compressive strength is high for 1.5% super plasticizer used sample. So 1.5% super plasticizer is recommended for high strength.

Published: January 2020

The practicality and the engineering properties of portland cement concrete (PCC) and three types of rubberized PCC mixes prepared by partially replacing the conventional coarse aggregate with rubber were examined. The rubberized PCC mixes contained 5%, 10% and 15% waste tyre rubber chips as replacement of conventional coarse aggregate. Different physical and mechanical properties of the control (0% rubber chips) and the rubberized concrete samples were determined. A 5% replacement of conventional aggregates resulted in a 5% reduction of compressive strength, a 10% replacement resulted in a 26% reduction and a 15% replacement resulted in a reduction of 47%. A 5% replacement of conventional aggregates resulted in a 6% reduction of tensile strength, a 10% replacement resulted in a 33% reduction and a 15% replacement resulted in a reduction of 53%. A 5% replacement of conventional aggregates resulted in a 13% reduction of flexural strength, a 10% replacement resulted in a 33% reduction and a 15% replacement resulted in a reduction of 42%. Although concrete made from tyres had lower strength than the normal concrete, rubberized concrete can find its use in landscaping, sports field ground, architectural finishing, lightweight concrete walls etc.
