The influence of the method of barley inclusion(fine,coarse and whole barley)in a wheat-based diet and protease supplementation(0 and 0.20 g/kg)on growth performance,nutrient utilisation and gastrointestinal tract development of broilers(d 1 to 21)was evaluated in a 32 factorial *** barley(WB)grains were ground in a hammer mill to pass through the screen sizes of 2.5 and 8.0 mm to achieve fine(FB)and coarse(CB)barley particle sizes,respectively.A total of 288,one-day-old male broilers were allotted to 36 cages(6 cages/treatment;8 birds/cage).There was no significant(P>0.05)interaction between barley inclusion method and protease for any growth performance or nutrient utilisation *** fed diets containing CB and WB showed higher(Pht gain,and digestibility of dry matter,nitrogen,calcium,gross energy,and ileal digestible energy compared to those fed FB *** to the birds fed FB diets,feed per gain was lower(Pmade of *** digestibility of the birds fed CB was higher(Phan those fed FB and WB *** to FB and CB diets,inclusion of WB resulted in heavier(Phowever,had no effects(P>0.05)on growth performance and nutrient utilisation,most likely due to the well balanced digestible amino acids and high inherent digestibility of protein in the basal diet,and/or the presence of exogenous carbohydrase and *** conclusion,the present results showed that the inclusion of coarsely ground and whole barley in a wheat-based diet can enhance nutrient and energy utilisation and is beneficial to the growth performance of young broilers.

The controls of soluble Al concentration were examined in three situations of acid sulfate conditions: 1)experimental acid sulfate conditions by addition of varying amounts of Al(Oh)3 (gibbsite) into a sequenceof h2SO4 solutions; 2) experimental acid sulfate conditions by addition of the same sequence of h2SO4solutions into two non-acid sulfate soil samples with known amounts of acid oxalate extractable Al; and3) actual acid sulfate soil conditions. The experiment using gibbsite as an Al-bearing mineral showed thatincrease in the concentration of h2SO4 solution increased the soluble Al concentration, accompanied bya decrease in the solution ph. Increasing amount of gibbsite added to the h2SO4 solutions also increasedsoluble Al concentration, but resulted in an increase in solution ph. Within the h2SO4 concentration rangeof 0.0005～0.5 mol L-1 and the Al(Oh)3 range of 0.01～0.5g (in 25 mL of h2SO4 solutions), the input ofh2SO4 had the major control on soluble Al concentration and ph. The availability of Al(Oh)3, however, wasresponsible for the spread of the various sample points, with a tendency that the samples containing moregibbsite had a higher soluble Al concentration than those containing less gibbsite at equivalent ph *** experimental results from treatment of soil samples with h2SO4 solutions and the analytical results ofacid sulfate soils also showed the similar trend.

In this paper we describe a route to produce crystalline mg（Oh）2 nanopowders from serpentinite ore distributed in the halilovskiy array （Russia, Orenburg region）. An efficient extraction route consisting of treatment on serpentinite in 40% hNO3 at 80 ℃followed by Nh4Oh titration for mg（Oh）2 precipitation was demonstrated. In this study, crystalline mg（Oh）2 nanopowders have been synthesized by solvothermal reaction method using （mg（NO3）2·6h2O） which were obtained from serpentinite, Nh4Oh as a precipitator, and hydroxyethylated nonylphenol as surface-active substance. microstructure and phase composition of samples were investigated employing scanning electron microscopy （SEm） and transmission electron microscopy （TEm）, X-ray phase analysis （XRD）, and inductively coupled plasma optical emission spectroscopy （ICP-OES）. XRD reveals that mg（Oh）2 nanopowder with high purity has the brucite structure. It was found that crystalline mg（Oh）2 nanopowders exclusively consist of lamellar-like structures and the sizes of mg（Oh）2 are 30-265 nm length or width.

Taxonomic placement of genera have been changing rapidly as taxonomists widely use DNA sequence data in phylogenetic and evolutionary studies. It is essential to update existing databases/outlines based on recent studies, since thesesources are widely used as a foundation for other research. In this outline, we merge both asexual and sexual genera intoone outline. The phylum Ascomycota comprises of three subphyla viz. Pezizomycotina (including 13 classes, 124 ordersand 507 families), Saccharomycotina (including one class, one order and 13 families) and Taphrinomycotina (five classes,five orders and six families). Approximately, 6600 genera have been listed under different taxonomic ranks includingauxiliary (intermediate) taxonomic ranks.

high resolution (4 mm) tof PET-CT (positron emission tomography-computed tomography) from Philips of model Ingenuity TF is newly installed at Institute of Nuclear medical Physics (INmP). 128 slice CT component incorporated with PET provides comparatively lower dose than the 511 keV annihilation photons associated with positron decay from PET scan. So, for designing shielding in our PET-CT facility, only 511 keV annihilation photons energy has been considered. The main objective of this paper is to show what measures have been taken to protect patients, occupational workers as well as environment from PET-CT radiation hazard through a cost effective design that satisfy the national regulatory demand. In this paper, AAPm (American Associations of Physicists in medicine) Task group 108 analysis for PET and PET-CT shielding requirements is followed for our PET-CT facility shielding design. From theoretical calculation as shielding requirement, 1.1 cm Pb thickness or, 13 cm concrete thicknesses are found. Practically, all walls and ceiling are of 30.48 cm (1 foot) thick made of concrete with density 2.35 gcm-3 for more safety. As x-ray from CT is not taken into account for shielding analysis, Bangladesh Atomic Energy Commission (BAEC) conducted an extensive radiation survey at controlled, supervised and public area for CT. The report that is found meets the national regulatory requirements.

Dry milling followed by ultrasonic irradiation in the presence of small amounts of aqueous NaOh, was used to synthesise ZnAl-layered double hydroxide （LDh）. The synthetic conditions were optimised and the Zn（Oh）2, ZnO, and AI（Oh）3 contaminants were removed by rinsing with aqueous Nh3 solution from the sample prepared in the optimum conditions. Thus, phase-pure ZnAl-layered double hydroxide was obtained with high crystallinity. All materials produced during the syntheses were characterised by X- ray diffractometry, and a rose-like morphology was observed by scanning electron microscopy in the phase-pure sample. By changing the initial Zn/Al ratio, it was revealed that an LDh with low zinc content was always formed, probably through substitution of some of the Zn2. ions by AI3. ions in the gibbsite lattice.
