Structural Design Optimization for Pedal Operated Paddy Thresher using Response Surface Methodology CIGR Journal
Khayer, Shadad Md; Patel, Thaneswer; Dewangan, Krishna Narayan.
Paddy is the main crop in India grown in about 44 million ha area. Threshing of paddy is one of the most widely used practice in India. Traditional methods of threshing are still prevalent in most of the parts of North-Eastern region. The farming community of the North-Eastern region faces some difficulties in adoption due to low productivity, inadequate design, and injuries during threshing.This study made an attempt to optimize the most significant design parameter of pedal operated paddy thresher (POPT) such as loop spacing, tip height, drum peripheral speed and number of the strip in the periphery of drum to achieve the optimum threshing capacity using Response surface methodology (RSM) in Design Expert v7 tool. From the analysis of variance (ANOVA),...

Lalitendu Das; North Carolina State University Biological and Agricultural Engineering; Praveen Kolar; North Carolina State University; Jason Osborne; North Carolina State University Department of Statistics; John Classen; North Carolina State University Biological and Agricultural Engineering.
Swine farming emit several odorous volatile organic compounds, one of which is p-cresol. Considering the layout of a swine barn, adsorption is one of the most suitable technologies for mitigating organic pollutants. In this study, commercial granular activated carbon (GAC) was tested as an adsorbent for removing p-cresol from aqueous solution. The objectives were to: 1) determine the combined effect of temperature, pH, and adsorbent dose on adsorption, (2) investigate the effect of volatile fatty acids and aldehydes on adsorption of p-cresol, (3) determine adsorption kinetics and isotherms, (4) study the effect of solvent on adsorption, (5) propose a possible mechanism of adsorption, and (6) discuss practical implications and design calculations for...

Beneficial effects of bio-controlling agent Bacillus cereus IB311 on the agricultural crop production and its biomass optimization through response surface methodology Anais da ABC (AABC)
BANERJEE,GOUTAM; GORTHI,SRIKANTH; CHATTOPADHYAY,PRITAM.
ABSTRACT Disease in agricultural field is a big problem that causes a massive loss in production. In this present investigation, we have reported a soil-borne bacterium Bacillus cereus IB311 which is antagonistic to plant pathogens (Pseudomonas syringae and Agrobacterium tumefaciens), and could make a substantial contribution to the prevention of plant diseases. To prove the practical application, the strain was directly applied in agricultural field. The results demonstrated that B. cereus IB311 has increased the production (20% and 26% in term of average pod number per plant, average seed number per pod, and seed yield per experimental plot) in ground nut (Arachis hypogaea var. Koushal, G201) and sesame (Sesamum indicum var. Kanak), respectively. To...

Response surface methodology to evaluation the recovery of amylases by hollow fiber membrane BABT
Severo Júnior,João Baptista; Oliveira,Laura Sampaio de Sá; Sardeiro,Fernanda Silva; Souza,Roberto Rodrigues de; Lopes,Francisco Luiz Gumes; Santana,José Carlos Curvelo; Tambourgi,Elias Basile.
This work aimed to study the pH and the transmembrane pressure effects during the recovery of alpha and beta amylases enzymes from corn malt (Zea mays) by hollow fiber membrane. The optimal condition was obtained for a statistical model, established by response surface methodology (RSM). The response surface analysis showed that the best operation condition for amylolitics enzymes recovery by hollow fiber membrane was 0.05 bar and pH 5.00, while the enzymes were purified about of 26 times.

Optimization of the production of extracellular α-amylase by Kluyveromyces marxianus IF0 0288 by response surface methodology BABT
Stergiou,Panagiota-Yiolanda; Foukis,Athanasios; Theodorou,Leonidas; Papagianni,Maria; Papamichael,Emmanuel.
The aim of this work was to study the production of extracellular α-amylase by Kluyveromyces marxianus IF0 0288 using optimized nutritional and cultural conditions in a complex yeast medium under aerobic batch fermentation. By applying the conventional "one-variable-at-a-time" approach and the response surface methodology, the effect of four fermentation parameters (type of carbon source, initial culture pH, temperature, and incubation time) on the growth and α-amylase production was evaluated. The production of α-amylase during 60 h of fermentation increased 13-fold under optimized conditions (1% starch, pH 6.0, 30ºC) in comparison to the conventional optimization method. The initial pH value of 6.13 and temperature of 30.3ºC were optimal conditions by...

Microencapsulation and Storage Stability of Lycopene Extracted from Tomato Processing Waste BABT
Ranveer,Rahul C.; Gatade,Abhijeet A.; Kamble,Harshwardhan A.; Sahoo,Akshya K..
ABSTRACT The aim of this study was to optimize the encapsulation of lycopene using response surface methodology and to determine its stability. The lycopene was extracted from tomato processing industry waste. The extracted pigment was purified by crystallization method. The effect of different process parameters, viz, core to wall ratio, sucrose to gelatin and inlet temperature on encapsulation efficiency (EE) and encapsulation yield (EY) were studied. Structural study of encapsulated material was carried by using scanning electron microscope (SEM). The samples with and without encapsulation were stored under different conditions such as the presence and absence of air, sunlight, at room temperature and under refrigeration. Highest EE (92.6 ± 0.86) and EY...

Yu,Ying; Zhou,Xiaoyu; Wu,Sheng; Wei,Tiantian; Yu,Long.
Background Lysozyme plays a crucial role in innate immunity with its well-recognized bacteriolytic activity. In this study, the influence of expression parameters (inoculation volume, culture volume, growth time, induction temperature and time, initial pH and methanol concentration) on human lysozyme (HLZ) production in recombinant P. pastoris SMD1168 was investigated through Plackett-Burman (PB) design and response surface methodology (RSM). Results It was revealed that induction temperature, induction time and culture volume had significant influence (P < 0.01) on HLZ expression level, which were elected for further optimization with three-dimensional response surface designs for enhanced HLZ production. The highest lysozyme activity reached 3301 U/mL...

Khusro,Ameer; Kannan Kaliyan,Barathi; Abdullah Al-Dhabi,Naif; Valan Arasu,Mariadhas; Agastian,Paul.
Background: Xylanase from bacteria finds use in prebleaching process and bioconversion of lignocelluloses into feedstocks. The xylanolytic enzyme brings about the hydrolysis of complex biomolecules into simple monomer units. This study aims to optimize the cellulase-free xylanase production and cell biomass of Bacillus tequilensis strain ARMATI using response surface methodology (RSM). Results: Statistical screening of medium constituents and the physical factors affecting xylanase and biomass yield of the isolate were optimized by RSM using central composite design at N = 30, namely 30 experimental runs with 4 independent variables. The central composite design showed 3.7 fold and 1.5 fold increased xylanase production and biomass yield of the isolate...

New marketing strategies in the development of regions, cities and settlements (villages) AgEcon
Vinarne Bellasz, Zsuzsa.
Regional- and settlement marketing (in the following: RSM) is a relatively young but dynamically developing branch of the science and practice of marketing. On the basis of the experience of the international as well as national regions and cities producing successful and impressive development it is often referred to as "wonder weapon" in the field of rural development. The task of RSM - to cut it short - is nothing else but the exploring of the competitiveness, comparative advantages and attraction of the region, the settlement, as well as the supporting of their realization and communication in the interest of the multifold aims concerning development, economics and lifestyle. In Hungary, RSM has been established by the increase of the self-governing...
