Two studies were conducted to examine the blood composition of cattle of different breed types. The first study involved 357 crossbred cows of Hereford × Angus, Charolais × British breed, Simmental × British breed and Limousin × British breed crosses, ranging in age from 12 to 14 yr. Sixteen blood characteristics were measured from the June and September blood samples. The second study used 23 Shorthorn cow-calf pairs from a line selected for yearling weight and 25 cow-calf pairs from a corresponding unselected control line of Shorthorns. These cow-calf pairs were bled 11 times, starting at ca

Abstract:

We propose a rich foundational theory of typed data streams and stream transformers, motivated by two high-level goals. First, the type of a stream should be able to express complex sequential patterns of events over time. And second, it should describe the internal parallel structure of the stream, to support deterministic stream processing on parallel and distributed systems. To these ends, we introduce stream types , with operators capturing sequential composition, parallel composition, and iteration, plus a core calculus λ ST of transformers over typed streams that naturally supports a num

How many bits or numbers are needed to characterize a typical composition? Can the rules of a composition type be expressed in the language of the computer? If distinct composition types require different computer programs, can these be based on a common frame-work, a mechanism, perhaps?

Three polygenic and polychronous siderite mineralizations were established in Kremikovci deposit: syn-diagenetic, hydrothermal and supergenetic, represented by 7 mineralogicalgenetic types of siderite. The syn-diagenetic siderites (I-III types) are micro- to fine-grained, with massive and rare finely-banded and organogenic structures. They are distinguished for relative uniformity and wide variations in grains' composition. They pertain to the magnesian-manganoan (I-II types) and manganoan-magnesian (III type) varieties. During the process of diagenesis the MgC03 content increases. Siderite II

Abstract:

Charcoal briquettes can be an alternative energy and can be produced from Gerunggang and Tumih types of wood. These two types of wood are commonly found in Kalampangan Village as pioneer plants on burned peatlands. The research objective was to determine the chemical properties of charcoal briquettes produced from biomass waste from land processing without burning with several compositions of Gerunggang wood and Tumih wood. The chemical properties of charcoal briquettes refer to the Indonesian National Standard (SNI 01-6235-2000) and Standard Permen ESDM No. 047 of 2006. The results showed tha

Abstract:

Abstract The study describes main biotopes of Socotra Island. The biotopes were distinguished and described during complex field observations on more than 250 localities of Socotra between years 1999-2004. Classification of biotopes is based on differences in physiognomy, structure and species composition of the vegetation component of present biocoenoses. Groups of biotope types differ, above all, in the physiognomy and structure of vegetation. Biotope types are divided according to composition of dominant species. In this manner, 13 groups of biotopes and 39 biotope types were distinguished

The relevance of the work is due to the importance of metasomatic rocks associated many ore and non-metallic mineral resources. Purpose of the work: study of temperature conditions of formation, the characteristics of the chemical and mineral composition, the mineralogy of metasomatites. Results. The extended classification of the main types of metasomatic rocks (alkaline, basic, acidic) formed in the early alkaline and acid stages of the hydrothermal process is given. Temperature conditions of formation, features of chemical and mineral composition and metasomatite mineralogeny are considered

Abstract:

Abstract Ancient Chinese glass is susceptible to weathering by environmental influences, and its chemical composition has changed considerably thus affecting the category judgment. The classification of ancient glass is mainly divided into two types: high potassium and lead-barium. In this paper, in order to determine the type of ancient glass according to its chemical composition, the multicollinearity phenomenon of many chemical compositions is reduced by using LDA model and then the parameters of XGBoost and RF models are optimized by using GA algorithm and the five-fold cross-validation of

Abstract:

Oases of Antarctica are unique landscape compositions located within the continent and, at a considerable distance from the coast. These are areas of glacier-free rocks and lakes that are free from snow in the summer and are characterized by a high peculiarity of conditions for the formation of communities of living organisms. Our studies performed on a wide variety of biotopes of Bunger Hills revealed the composition and structure of algocenoses of these habitats, as well as to establish their common features and characteristic differences.

Abstract:

The size and floristic composition of soil seed banks under four adjacent, unlogged and structurally different rainforest types were assessed by exposing 17 surface soil samples (to 40mm depth) to germination-house conditions. The mean size of the seed bank in the undisturbed forest types was 240 seeds m-2 (s.d. 139). Seeds of secondary species dominated the soil seed banks in all forest types, although weed seeds constituted only 0.6-4.0%. Some forest types had characteristic component secondary species in the buried seed bank. Agglomerative classification and multidimensional scaling analysi
