Three different methods of estimating airborne bacteria were compared. An Anderson sampler, a slit sampler, an impinger, and filter samplers with gelatine filters or membrane filters were tested for collection efficiency. The comparisons were made in laboratory experiments with an aerosol of Staphylococcus epidermidis or Serratia marcescens, in field experiments in two different industries, i.e...

The treated and untreated effluent sample from Sir Shadi sugar mill Ltd. Shamli Distt Muzaffarnager of Western Utter Pradesh India during 2011-12 were collected and brought into laboratory for studying Physico-chemical parameters like Color, temperature, pH, DO, BOD, COD, TDS, TS, TSS, Chlorides, Sulphate and Oil & grease, heavy metals seed germination pattern of some important cereal crops. Un...

Chemical analyses of iron ore samples are crucial to identifying the characteristics being mined and processed by mining industries. Moreover, reliable content results fundamental optimizing plant operation correctly pricing final product. An industrial laboratory usually performs hundreds per day requires a certain amount equipment increase capacity. However, parallel chemical approach demands...

Cereal Chem. 84(3):271-275 Wheat protein quantity and composition are important parameters for wheat baking quality. The objective of this study was to use fractionation techniques to separate the proteins of flour mill streams into various protein fractions, to examine the distribution of these protein fractions, and to establish a relationship between protein composition and breadmaking quali...

Ceramic passive samplers or toximeters (packed with active carbon 1%, w/w, on celite), in combination with the CALUX bioassay have been used as a time-integrated monitoring technique for dissolved dioxin-like PCBs in urban and industrial wastewaters. The technique showed to be reliable during laboratory experiments: (1) PCB-126 amounts extracted from the passive samplers increased linearly with...

Many procedures have been described (Umbreit et al., 1957) for the mechanical rupturing of yeast and bacterial cells. These techniques vary from simple hand grinding with abrasives to the use of extrusion or high speed shaking devices. These techniques, although generally satisfactory when dealing with small quantities of cells, are unsuitable for breaking larger quantities of cells required in...

Formation of substituted lithium ferrite Li0.5SmxFe2.5–xO4 (where x = 0.06 and 0.2) from Sm2O3/Fe2O3/Li2CO2 precursors was studied by X-ray diffraction analysis, thermogravimetry, differential scanning calorimetry, electron microscopy. The mixture powders subjected to preliminary mechanical activation in a planetary mill. We analyzed samples based on the synthesized at 900 °C for 4 h laboratory...

It has long been known that gastric mill network activity (cycle period 5-10 s) alters pyloric network output (cycle period approximately 1 s), but these effects have not been quantified. Many pyloric muscles extract gastric mill timed variations in pyloric motor neuron firing, and consequently produce gastric mill timed movements even though no gastric mill neurons innervate them. Determining ...

who by the time he had passed his final medical examination at the age of 40 had been a steel mill melter, a locomotive fireman, a barman, an insurance salesman, and a whisky pedlar, and also a medical student (off and on) for 18 years. After obtaining his qualification in 1948 he spent some time working at a general hospital, and this was followed by a highly successful period as a family doctor.

Simultaneous endoscopic and electrophysiological recordings were used to observe the behavior of the gastric mill complex while recording the motor output of the stomatogastric ganglion (STG) in intact crabs. In the crab STG, many pattern-generating neurons are able to fire in several distinct rhythmic motor patterns. Specifically, many neurons can switch between firing in time with the rapid p...
