Several variables affected the production of catalase by members of the "Bacteroides fragilis group" of anaerobic bacteria. Both media yielded higher catalase levels than the respective agar media. Addition of hemin to media after autoclave sterilization, rather than before, significantly increased production of catalase. Both of these variables could be related to the available hemin concentr...

We provide simple and unified indifferentiable security analyses of choppfMD, chopMD, a chopMDP (where the permutation P is to be xored with any non-zero constant.), chopWPH (the chopped version of Wide-Pipe Hash proposed in [16]), chopEMD, chopNI, chopCS, chopESh hash domain extensions. Even though there are security analysis of them in the case of no-bit chopping (i.e., s = 0), there is no un...

 Background: The manufacturing of frozen shrimp is an important industry for the economy of Thailand. The objective of this study was to use Near-Infrared (NIR) spectroscopy to determine the freshness quality, including Total Volatile Basic Nitrogen (TVB-N) and Water Holding Capacity (WHC) of white shrimp (whole and chopped shrimp) and phosphate residues of shrimp. Methods: Sixty white shrimp ...

The light-supported component of (36)Cl uptake from 5 mM K(36)Cl by green laminae, either chopped or vacuum-infiltrated, of Triticum aestivum L. seedlings has been determined by subtraction of dark uptake values from light uptake values and the energy sources for the uptake elucidated on the basis of the effects of 3-(3,4-dichlorophenyl)-1,1 dimethylurea (DCMU), carbonyl cyanide p-trifluorometh...

Large-format imaging arrays are best operated in scanning observing modes rather than traditional positionswitched (chopped) modes. The choice of observing mode is critical for isolating source signals from various types of noise interference, especially for ground-based instrumentation operating under a bright atmosphere. Ideal observing strategies can combat 1/f noise, resist instrumental def...

The article presents research results of a machine-tractor unit that performs two technological operations simultaneously: (i) chopping plant residues (sunflower stubble); (ii) covering the chopped stubble with soil. first operation is carried out front-mounted chopper, and second one rear-mounted plough. chopper’s working devices are rotated by tractor’s front power take-off (PTO), which has o...

There is inconsistency between current in vitro digestion methods with regard to accommodation of a (salivary) α-amylase exposure during the oral phase. The effect of a salivary α-amylase pre-exposure on subsequent in vitro starch digestion curve profiles for various foods was investigated. Foods were chewed, expectorated and the boluses left to rest for 0-15 min. During pancreatic digestion, a...

BACKGROUND Almond processing has been shown to differentially impact metabolizable energy; however, the effect of food form on the gastrointestinal microbiota is under-investigated. OBJECTIVE We aimed to assess the interrelationship of almond consumption and processing on the gastrointestinal microbiota. DESIGN A controlled-feeding, randomized, five-period, crossover study with washouts bet...
