Conservation of energy usage is essential in chemical process plants due to the expanded users and demands alongside carry-on hike prices. This study analyzed performance savings a heat exchanger network (HEN). It based on decreasing utility while increasing process-to-process exchange HEN using path combination approach at different recovery temperatures (HRATs). The generates combined options...

This work considers improving the heat recovery of an existing heat exchanger network (HEN) while minimizing the total annualized cost of the retrofit design. The focus is on stepwise approaches that generate, starting from the base case network, a candidate retrofit HEN at each step in order to sequentially retrofit the HEN topology while permitting user intervention during the resolution proc...

The study was conducted to determine the effect of varying protein levels and preservation method on external egg qualities of Japanese quails. A total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (CRD) replicated six times. A factorial arrangement of 3 × 4 × 4 which involves 3 protein levels (15, 20 and 25% crude protein), 4 storage method...

A study was conducted to evaluate the effects of two laying systems (floor versus cage) on egg production, egg quality, and microbial safety. One hundred and eighty 42 wk old laying hens were separated into two groups of 90 hens each, and housed in laying cages and a floor laying system. Eggs from the hens were collected for 2 weeks, and hen-day egg production, egg quality (whole egg, albumen, ...

Peneliti melakukan penelitian ini karena masih banyak yang belum tau apakah dalam proses pembentukan kata bahasa Indonesia takarir anime Jepang Kimetsu No Yaiba Movie Mugen Ressha-Hen itu sesuai apa tidak dengan ranah morfologi khususnya pada morfofonemik, maka hal tersebut fokus terletak pada: 1. Bagaimana jenis morfofonemik saja terdapat Ressha-Hen? 2. Ressha-Hen?. Tujuan penelitian: Mengetah...

Free-energy landscapes decisively determine the progress of enzymatically catalyzed reactions [Cornish-Bowden (2012), Fundamentals of Enzyme Kinetics, 4th ed.]. Time-resolved macromolecular crystallography unifies transient-state kinetics with structure determination [Moffat (2001), Chem. Rev. 101, 1569-1581; Schmidt et al. (2005), Methods Mol. Biol. 305, 115-154; Schmidt (2008), Ultrashort Las...

Alternative hen housing is becoming more commonplace in the egg market. However, a complete understanding of the implications for alternative housing systems on egg safety has not been achieved. The current study examines the impact of housing Hy-Line Brown, Hy-Line Silver Brown, and Barred Plymouth Rock hens in conventional cage, cage-free, and free range egg production systems on shell microb...

The paper presents a Process Integration application for waste heat utilisation from exhaust gas streams with partial condensation. It is based on the hot composite curve construction representing gaseous mixture cooling accounting condensable vapour part's gas–liquid equilibrium. With cold requiring heating, Pinch Point determined. On this basis, exchanger network (HEN) structure utilised inte...

Heat inactivation was studied at 45, 50, 55, and 60 degrees for all of the phenyl valerate hydrolases (PVase), including neurotoxic esterase (NTE) and inhibitor-resistant esterase (IRE), in homogenates of hen or rat brain or in preparations of hen brain microsomal membranes. Hen and rat brain homogenates were prepared in buffer (50 mM Tris/0.20 mM EDTA, pH 8.00, at 25 degrees). Hen brain micros...

A strategy is proposed for the synthesis of a flexible heat exchange network (HEN) that involves specified uncertainties in the source-stream temperatures and flow rates. The problem is decomposed into three main iterative steps: (1) the simultaneous HEN synthesis to attain a network configuration with a minimum total annual cost (TAC); and (2) the flexibility analysis to test the feasible oper...
