Comparative study on phase changing material for refrigeration effect for milk chilling CIGR Journal
Sharma, Amandeep; Gupta, Silvy; Kaur, Kulwinder.
 In developed countries the milking collection is done to process in various diary plants situated far away from production areas.  There is a problem of cool chain management, which, generally is absent at farm levels.  To manage the cool chain in milk transportation system right from farm level it is required that some locally available techniques/materials should be selected and used for milk chilling.  The objective of current study is to ascertain mechanism for chilling of milk at farm immediately after milking.  The experiments were conducted and the cooling performance was evaluated by noting down the drop in temperature with respect to time using mercury thermometer.  The respective regression equation and R2 value were obtained for every run of...

Expanded perlite/cork fillers applied to aerospace insulation materials Anais da ABC (AABC)
PINTO,JULIANO R.A.; SANCHES,NATALIA B.; DINIZ,MILTON F.; SANTOS,RÉGIS S.; OLIVEIRA,JOSÉ I.S. DE; DUTRA,RITA DE CÁSSIA L..
Abstract Insulations for rocket motors such as Flexible Thermal Protections (FTPs) and Rigid Thermal Protection (RTPs) act as thermal barriers against the hyperthermal environment from the solid propellant combustion. FTPs present dual function: to extend RTPs performance, and to attenuate the propellant contraction. FTPs used in the Brazilian Space Program have asbestos in their composition since the 70´s; however, they are hazardous for human health. In this context, a mixture of Expanded Perlite (PExp) and Cork Powder (CP) was investigated as a replacement for asbestos. Results showed reduction about 21 % in density and an increase of 13 % in the ablative properties. The low mechanical properties not interfere in this type of FTP due to your function of...

Sperm Morphological Characteristic and Mating Behaviour of Proviron® Treated West African Dwarf Bucks with Testicular Degeneration International Journal of Morphology
Adeniji,Deborah Adejoke; Oyeyemi,Matthew Olugbenga; Olugbemi,Joshua Bolaji.
This study was conducted to determine the effect of scrotal insulation and post insulation Proviron® treatment on sperm morphological characteristics and mating behavior. Twelve healthy WAD bucks, free from any clinical or andrological disorder were used. Scrotal insulation was done using insulating bags for 30 days. After insulation, the bucks were divided into two groups. The treatment group received 100mg/head /week of Proviron® for 3 weeks. Semen collection was done using the electroejaculation method in all phases of the study. The proviron® treated bucks, when compared with insulation and post insulation untreated phases, showed significant reduction (p<0.05) in sperm cell abnormalities which reduced from 15.89±22.89 in post insulation untreated...
