Business Rationale for Investment on Power Operated Maize Sheller in Bangladesh CIGR Journal
Swapan K Roy; Mike Albu; Abdur Rob.
A study was carried out to investigate the investment of a selected agro-machinery power operated Maize Sheller in the course of mechanization of Bangladesh. The analysis considers different types of Maize Sheller, and inter-regional differences in agro-economic factors that influence the business rationale for investment. Maize Shellers are increasingly needed to serve demand from poultry sector because manual shelling is very laborious. Comparing with manual shelling, results indicate that power operated Maize Shellers look like a wise investment (5 – 8 acres for 25% internal rate of return or IRR). However, it makes economic sense to operate shellers at higher capacities, and along with the high capital cost (Tk1 18,000 – 22,000) to save large numbers...

Carbon Dioxide Production in Animal Houses: A Literature Review CIGR Journal
S. Pedersen; V. Blanes-Vidal; H. Joergensen; A. Chwalibog; A. Haeussermann; M. J. W. Heetkamp; A.J.A. Aarnink.
This article deals with carbon dioxide production from farm animals; more specifically, it addresses the possibilities of using the measured carbon dioxide concentration in animal houses as basis for estimation of ventilation flow (as the ventilation flow is a key parameter of aerial emissions from animal houses). The investigations include measurements in respiration chambers and in animal houses, mainly for growing pigs and broilers.Over the last decade a fixed carbon dioxide production of 185 litres per hour per heat production unit, hpu (i.e. 1000 W of the total animal heat production at 20 oC) has often been used. The article shows that the carbon dioxide production per hpu increases with increasing respiration quotient. As the respiration quotient...

Carboniferous Productidina and Chonetidina of the Cantabrian Mountains (NW Spain): Systematics, stratigraphy and palaeoecology Naturalis
Winkler Prins, C.F..
The Carboniferous sediments of the thrust structures between the Porma and Bernesga rivers (map 2) and the headwaters of a tribuary of the Luna River (map 3) are described. In the lithostratigraphic chapter, the Vegamián, Alba, Escapa and San Emiliano formations are described, ranging in age from the Tournaisian to the lowermost Westfalian. The Alba and Escapa formations are subdivided into three and two members, respectively. An attempt has been made to reconstruct the palaeoecological conditions during sedimentation. The palaeoecological interpretation is based mainly on the productoids and chonetoids, but other palaeontological and lithological evidence has also been used. Many faunal assemblages have been found, which are comparable to those described...

Carboniferous Sphinctozoa from the Cantabrian Mountains, Spain Naturalis
Graaff, W.J.E. van de.
In Westphalian strata of the Cantabrian Mountains, northern Palencia, Spain, the sphinctozoan sponges Amblysiphonella and Cystauletes are quite common; Sollasia is much rarer. This is the first occurrence of Cystauletes in Europe. The great variability of Amblysiphonella barroisi and Cystauletes mammilosus is demonstrated with abundant material. One new species Cystauletes maior is described. All three genera are associated with Dasycladaceae, which indicates a very shallow water environment.

Caribbean Bomolochidae (Copepoda: Cyclopoida) Naturalis
Vervoort, W..
The material on which the present report is principally based, was collected by Dr. J. H. STOCK, Zoological Museum of the University, Amsterdam, in Piscadera Bay, Curaçao, in 1958 and 1959, and kindly placed at my disposal some time ago. In the course of my study of this highly interesting material it became necessary to redescribe some of C. B. WILSON’S fragmentarily known species of Bomolochidae. A re-inspection of some of WILSON’S types has been made possible thanks to the generous co-operation of Dr. THOMAS E. BOWMAN, Associate Curator, Divison of Marine Invertebrates, and Dr. ROGER F. CRESSEY, Associate Curator, Division of Crustacea, both of the Smithsonian Institution (United States National Museum), Washington, U.S.A. The bulk of the Piscadera Bay...
