This study was conducted to evaluate the effects of raw and autoclaved Amaranth grain on the performance and egg quality of layer hens. For this purpose 168 Leghorn laying hens strain Hy-line W36 at 67 weeks of age were allocated in completely randomized design with 7 treatments and 6 replicates of 4 birds. Treatments include raw and autoclaved Amaranth each at 0, 5, 10 and 15%. The egg exte...
BACKGROUND The spread of antibiotic-resistant pathogens represents an increasing threat in healthcare facilities. Concern has been expressed that the use of surface disinfectants and antiseptics may select for antibiotic-resistant pathogens. OBJECTIVE To review the scientific literature on whether there is a link between use of germicides (ie, disinfectants and antiseptics) and bacterial resi...
Organic-inorganic perovskite (CH3NH3PbI3), due to an appropriate energy gap to absorb sunlight, is used as an absorbent layer in third generation solar cells. Crystallinity of light absorbing layer plays an important role in the performance of perovskite solar cells and substrate plays an important role on crystallinity of light absorbing layer. In superstructure solar cells, alumina (aluminum ...
Background and purpose: In recent decades, various efforts have been made to replace synthetic materials with natural disinfectants that have less disadvantages and lead to similar or even better results. The present study was conducted to compare the effect of Artemisia aucheri and Zataria multiflora as natural disinfectants with those of Deconex and sodium hypochlorite as two industrial disin...
introduction: induced molting is a process that stimulates natural molting events. when birds return to full feed, a new plumage develops and the birds resume egg peroduction at a higher rate with better egg quality. induced molting extends the productive liffe of commercial chicken flocks and results in substantial reduction in the number of chickens needed to produce the nation's egg supply. ...
in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
In an effort to evaluate and control the potential hazard and inherent risk of environmental transmission and spread of nosocomial infections by contact with hitherto “non-critical” inanimate/environmental surfaces in the hospital and healthcare facilities (commode, bed, bowl of toilet etc.), the microbicidal efficacies of six disinfectants products commonly used in local hospital facilities wa...
Theexperiment was conducted to investigate the growth performance and feed conversion efficiency of crossbred heifer at different age level in Government Dairy Farm in Bogra, Bangladesh. Twelve female crossbred heifers were equally distributed (n=3) into four groups [Group A: (7±2 months), B: (12±2 months), C: (15±2 months) and D: (20±2 months)] according to age and fed concentrate mix, rice st...
Polyamide (PA)-based membranes are widely used in reverse osmosis (RO) and nanofiltration (NF) but can react with chlorine-based disinfectants (free chlorine chloramines) applied for biofouling control. This study examined how chloramines affected PA layer reactivity performance when individual mixed halides (Cl − , Br I ) were present, since these reactants form a host of different halogenatin...
