Title : A Non-Automatic Step Elution Chromatography for Purification of Recombinant Papain-like Protease from SARS-CoV2
Epi Taufik, , Cahyo Budiman, , Muhamad Arifin,
Abstract : The papain-like protease (PLpro) of SARS-CoV2 is an attractive target for the development of novel drugs to combat COVID-19. However, discovering effective drug candidates often requires the production of recombinant PLpro with high purity and yield. Unfortunately, this process often involves automated chromatography systems that require expensive and sophisticated equipment. This study aimed to purify recombinant PLpro using a manual Ni-NTA chromatography system with a step elution approach. In

Title : Adaptive Approach towards Effect of Process Variations Applicable to Digital and Analog Circuits
KUMARASWAMY K V, , Vijayaprakash A. M,
Abstract : In present day almost all FPGA and ASIC in every application PLL are the part of the chip. With any variation in PLL frequency the complete performance of the design would be affected. At Deep Submicron technology nodes threshold voltage Vth shift will happen at different corners due to manufacturing process. When designer squeezes to achieve maximum performance and low voltage, the shift in Vth impacts the complete circuit/chip performance in addition to temperature variation. Present day appli

Title : Design And Devlopment Of Circular Inspired Uwb-Mimo Patch Antenna
vishal mishra, , Dr puneet khanna, , Priyadarshi Suraj,
Abstract : In The present work a circular inspired dodecagon shaped monopole patch antenna having a compact size of 30x22mm2 in MIMO configuration has been proposed. The proposed antenna is covering entire UWB band (2.-11 GHz) having a better isolations approx. -25 dB in the entire operating band, also it exhibits a better performance in terms of ECC and Diversity gain. The simulated and measured response are in a very close agreement to each other.

Title : Indicator of Economic Reliability of Land Equivalent Ratio Based Dry Matter Yield of Intercropped Indigofera (Indigofera zollingeriana) and Brahum (Brachiaria humidicola)
Tilly F. D. Lumy, , Franky N. S. Oroh, , Jemmy E. O. Rawis, , Nontje J. Kumajas, , Wilhelmina B. Kaunang, , Malcky M. Telleng,
Abstract : This decision was made in order to choose between the got crops leguminosae Indigofera zollingeriana (Iz) and Brachiaria humicola (Bh), a tropical grass. The purpose of this consideration was to investigate the apparent magnitude of this received change in light of bearing limit and abandonment. The plan for this test was completely random, and for combination planted (C), it used a combination of four drugs from the planted area: C1, Iz, with dimensions of 1.0 m x 1.0 m and Bh, with dimensions

Title : The Effect Of The Combination Of Material Composite From Coconut Fiber and Banana's Mid Rib As A Sound Absorber
Laily ulfiyah,
Abstract : In this research, natural fibers are used as composite materials as sound absorbers because they can reduce noise. Sound absorbers from natural fibers can reduce noise. It consists of a combination of coconut fiber and banana midrib as a filler and PVAC glue as a matrix. The variations of ratio of the coconut fiber and banana’s mid ribs are 1:1, 2:1, 1:2. To bind the material, PVAc glue was implemented, with its thickness ratio= 2 mm, 3 mm, and 4 mm. The sound-absorbing coefficient value refers
