The problem of food security has always been an important and urgent concern for Indonesia. greater uncertainty in production, price volatility, increased demand due to population growth rising incomes, uncertain climate change, natural disasters are still latent problems. Strategic, sustainable, comprehensive efforts that can overcome these challenges must be immediately carried out ensure the...

Reversible operation of a microtubular solid oxide fuel cell SOFC with high electrochemical efficiency is reported. These devices can ideally produce hydrogen from electricity and steam solid oxide electrolyser SOE and then use the stored hydrogen to generate electricity and heat SOFC , acting as a storage device for the electrical energy. A fuel-electrode-supported Ni–yttriastabilized zirconia...

Over the past years, new memory technologies such as RRAM, STT-MRAM, and PCM have emerged. These technologies employ devices located within the metal layers of the chip, which are relatively fast, dense, and power efficient and can be considered as 'memristors'. To date, research in these devices has primarily focused on memristors as flash, DRAM, and SRAM replacement. In this presentation, we ...

Pitch period and amplitude perturbations are widely used parameters to discriminate normal and voice disorder speech. Instantaneous pitch period and amplitude of glottal vibrations directly from the speech waveform may not give an accurate estimation of jitter and shimmer. In this paper, the significance of epochs (glottal closure instants) and strength of excitation (SoE) derived from the zero...

objective: rna interference (rnai) is the most potent technique for gene silencing in eukaryotic cellular system at transcriptomic level. genetic disorders and cancers are important targets for therapeutic development of this technique. in order to bypass the temporary dpwnregulation by sirna, a new generation of shrna named shrnamir has developed. silencing construct with structure similar to ...

In the current economic context, enterprises are struggling to obtain competitive advantages on the market, by exploiting the opportunities offered by information technology. The research in this paper aims to encourage the use of modern approaches in order to increase enterprise agility, through the transition to Service-Oriented Enterprise (SOE). The proposed solution is based on reaching a s...

A novel HCPV nonimaging concentrator concept with high concentration (>500x) is presented. It uses the combination of a commercial concentration GaInP/GaInAs/Ge 3J cell and a concentration Back-Point-Contact (BPC) concentration silicon cell for efficient spectral utilization, and external confinement techniques for recovering the 3J cell’s reflection. The primary optical element (POE) is a flat...

Following previous research on management efficiency of state-owned enterprises (SOEs) in Lithuania, this paper continues discussion via extension the observed time period seeking to continuously analyze impact corporate governance principles effectiveness Lithuanian SOEs.For purpose study, elements established initial reform SOEs Lithuania are used as key dependent variables measure and quanti...
