Changes in soil organic matter (SOM) content and carbon (SOC) stock the 0–30 cm 30–100 layers between 1998 2018 Netherlands were estimated by repeated sampling of 1152 locations Soil Sampling Programme (SSP). These selected following a stratified simple random design. We discuss various barriers we met: restricted accuracy information on bulk density, uncertainties due to positional errors, dif...

the effects of a multi enzyme were evaluated on performance and nutrient digestibility in african domesticated ostrich at 14 months ages. there were three treatments as; common diet (1), common diet plus multi enzyme (0.350 gkg -1) (2) and common diet plus multi enzyme (0.700 gkg -1) (3). 18 ostrich were used in this experiment (6 birds per treatment). there was significant effect of enzyme sup...

Among other results, we rationally calculate the algebraic K-theory of any discrete cocompact subgroup of a Lie group G, where G is either O(n, 1), U(n, 1), Sp(n, 1), or F(4), in terms of the homology of the double coset space Gamma\G/K, where K is a maximal cocompact subgroup of G. We obtain the formula K(n)(ZGamma) [unk] [unk] congruent with [unk](i=0) (infinity)H(i)(Gamma\G/K; [unk](n-i)), w...

A study was conducted in the alluvial soils located in Oko-anala in Delta State, Nigeria. These alluvial soils are primarily used for intensive vegetable production for commercial purposes. The total land area of about 3.34 Square kilometer was divided into three consociations and composite soil samples collected from pre-determined depths of 0-15 and 16-30cm. The samples were routinely prepare...

Rice is the major staple food in a large part of the world, especially in Asia. Hypersensitivity reactions to rice are rare. Moreover, cases of occupational allergies induced by inhalation of rice powder are uncommon. We report a 31-year-old male with work-related rhinitis and conjunctivitis symptoms caused by occupational exposure to rice powder in the grain industry. He showed positive respon...

Pollen substitute diets are a valuable resource for maintaining strong and health honey bee colonies. Specific diets may be useful in one region or country and inadequate or economically unviable in others. We compared two artificial protein diets that had been formulated from locally-available ingredients in Brazil with bee bread and a non-protein sucrose diet. Groups of 100 newly-emerged, adu...

BACKGROUND AND AIMS Eryngium alpinum (Apiaceae) is an endangered perennial, characteristic of the Alpine flora. Because the breeding system influences both demographic (reproductive success) and genetic (inbreeding depression, evolutionary potential) parameters that are crucial for population maintenance, the reproductive ecology of E. alpinum was investigated. Specifically, the aims of the stu...

This study was done to investigate the effects of varying dietary protein levels (DPLs) and season on fecal microbes and odorous compounds in growing and finishing pigs. Thirty-six Landrace pigs were blocked based on their body weight and within each block assigned to one of the three dietary treatments (3 replicates (pens) per treatment). The DPLs used in the growing stage were 142.7, 155.4 an...

weed pollen grains belonging to  the  asteraceae  family contain  a variety of  allergens inducing type i  and iv allergies in susceptible people. the  aim of this research was to compare  the  allergenic properties  of  immature  and  mature  shasta  daisy pollen  grains (chrysanthemum maximum ramond) to define the potential role of the maturation process on the allergenicity of asteraceae pol...

Consider a study where the times of occurrences of a recurrent event for n units are monitored. For the ith unit, T(i1), T(i2), …, denote the successive event interoccurrence times and this unit is monitored over a random period [0, τ(i)] with τ(i) independent of the T(ij)s. Over this monitoring period, [Formula: see text] is the random number of event occurrences. The T(ij)s are independent an...
