the objective of this study was to compare different antigen preparations to produce monoclonalantibodies against bovine leukaemia virus gp51su. the four antigen preparations for immunization ofbalb/c mice were: cl: blv-flk cell lysate, uf: a fraction of cl (between 30 and 100 kda), wvp: wholevirus particles and sp: with ion exchange chromatography, gp51su was semipurified. a total of ninesucce...

The active emulsified blend films based on gelatin-pectin (5% w/w) containing virgin olive oil (VOO) (0.1–0.3 g/g biopolymer) and grape seed (GSO) were prepared by casting method. GSO showed slightly more decreasing effect than VOO ultimate tensile strength (UTS) strain at break (SAB) of however; had reducing the water vapor permeability (WVP). scanning electron microscopy (SEM) images that inc...

The combination of natural environment changes and human activities affects the growth grasslands. In order to quantitatively assess causes spatial temporal variation grasslands in Xilingol, this study assessed evolution patterns grassland health based on MOD13A1 long time series Normalized Difference Vegetation Index (NDVI) data from 2000–2019 using trend analysis. geodetector model was used e...

Edible packaging materials have widespread applications in pharmaceutical industries. In this study, the physical, thermal, colour, mechanical, and water barrier properties of a novel edible film based on pullulan (PUL) carboxymethyl cellulose (CMC) were investigated. The blend films made by solution casting method with 3 g total solid content. following percentages 100/0, 75/25, 50/50, 25/75, ...

Abstract Poliblend edible coating of suweg starch-chitosan (SSC) was prepared as a package with the addition essential oil from sweet orange peel antibacterial because high limonene content (95%) to increase shelf life malang’s apples. There are 6 variations formulation starch: chitosan, namely 10: 0, 9: 1, 8: 2, 7: 3, 6: 4 and 5: 5 in total volume 60 mL. Essential added concentration is 0%; 2%...

in the past decades, environmental pollution caused by plastic packing materials, restrictions of petroleum resources and their high price attracted many researchers to produce biodegradable packaging materials. poor mechanic properties and high water vapor permeability are two main defects of biodegradable polymers. nanotechnology is a modification method in this case. in the current study, th...

To better understand the effects of ambient relative humidity (RH) on physiological variables and the implications of RH-correcting evaporative water loss (EWL) data for marsupials, we examined the effect of RH on EWL, body temperature (Tb), metabolic rate (MR) and thermal conductance (C) of the brushtail possum (Trichosurus vulpecula), a medium-sized marsupial. Correcting EWL data for 27 speci...

Biofunctional quadripartite films were developed by adding trans-Cinnamaldehyde (CIN) (0.4, 0.8, and 1.6% w/v) into chitosan (CH)/poly(vinyl alcohol) (PVA)/fish gelatin (FG) matrices. Rheological data revealed that all solutions exhibited shear-thinning typical entangle polymers behavior. Mechanical results showed the incorporation of CIN caused a significant increase (p < 0.05) in tensile stre...

Eco-friendly and greener barrier materials are required to replace the synthetic packaging as they produce a threat environment. These can be fabricated by natural polymers such cellulose nanofiber (CNF). The sustainability of CNF was so amazing due its potential for circular economy provides alternative platform plastics. challenging task fabricate films still existed also current methods have...
