Determinación del costo del beneficio húmedo del café, en el departamento de Nueva Segovia, durante el ciclo agrícola 1965/66

El presente trabajo sirve como una modesta contribución a los estudios que sobre el cultivo del café y su beneficio deben todavía hacerse en Nicaragua y como tema de tesis para el autor. El objetivo fue investigar el costo de la fase húmeda del beneficio húmedo, conocida también con este ultimo nombre, en el departamento de Nueva Segovia. Para ello se elaboro una boleta con 7 secciones en base a las diferentes operaciones que se suceden durante el beneficio y los gastos variables y fijos que ellas ocasionan. Se determinaron los centros productores de café y se estimo encuestas del 10 al 20% de la superficie departamental sembrada con café, agrupando todas las explotaciones que siembran café en tres stratos: de 1 a 100 manzanas, de 100 a 500 manzanas y 500 y mas manzanas, de los cuales al primero correspondería el mayor porcentaje de la muestra, al segundo el porcentaje intermedio y al tercero, el menor. La encuesta se realizo del 23 de enero al 9 de febrero inclusive de 1966, actuando de empadronador único el autor del trabajo. Se obtuvo como muestra el 16.1% del área sembrada con café en el departamento y la información obtenida se vació en una manta-cartulina preparada al efecto. por municipio. Por aparte se obtuvo la misma información, por strato. La encuesta abarco un total de 34 productores propietarios de 42 fincas en las que se siembra café, las que se encuentran agrupadas en 36 unidades de explotación. Los datos recopilados convenientemente dieron como resultado que en el departamento de Nueva Segovia el costo del beneficio húmedo de 1 quintal oro de café en el ciclo agrícola 1965/66, fue de C$35.60 (Treinticinco córdobas y sesenta centavos de córdobas). La proporción en que los stratos se acercan o se alejan del promedio departamental se atribuye a la eficiencia o deficiencia de las técnicas administrativas empleadas.

The 66 k-Da protein identified as a light meromyosin is involved in the setting of surimi

The 66 kilo-Dalton (k-Da) protein split off from the cross linked myosin heavy chain (CMHC) formed due to the setting of Alaska pollack surimi, frozen-storage of Pacific cod flesh, and vinegar-curing of Pacific mackerel mince was identified as a light meromyosin (LMM). Puncture and stress-relaxation tests showed that the actomyosin subunits (AMS) of Alaska pollack surimi, upon setting at 30°C, transformed into gel, although the elasticity of this gel was very low when compared to the gels from surimi or actomyosin (AM). Electrophoretic studies showed that the band due to LMM in the gel from AMS gradually disappeared with the progress of setting but higher molecular weight polymer did not form. The intensity of the bands due to other myosin sub-fragments decreased a little. The findings suggest that at setting temperature, LMM of MHC molecule leads to an unfolding resulting in an intramolecular aggregation through non-covalent interactions, and thus plays a significant role in the crosslinking of MHC.

On the troll line investigations off Cochin during five fishing seasons. Pt. 3. Investigations during 1965-66 and 1966-67 seasons

During these two seasons investigations were carried out with a view to exploring the possibility of this operation on commercial basis and to study the effect of certain meteorological factors on catch.

A review of the fisheries of the Uganda waters of Lake Albert East Africa, 1928-1965/66, with catch data mainly from 1953

An historical account is given of the development of the Lake Albert fisheries since Worthington's survey in 1928. It is noted that the development of the fisheries was related to, and dependent upon, improvements in the type of gear and canoes, an incFease in the number of canoes and outboard engines in use, improved marketing facilities and better road communications. Summarized data, collected mainly since 1954, has been analysed and tabulated to show annual exports to the Congo, total annual catches 'and annual catches of individual species. A change in the relative abundance of the various species in the annual catches is described. It is noted that this change was caused by a change-over from large to small mesh size gill-nets, and that it was associated with an increased demand within Uganda for the smaller species of fish, such as Aleste's baremose and Hydrocynus forskahlii. A brief description of fish processing and marketing in the Lake Albert region is given, which emphasizes the suitability of salt-cured fish to the social and physical environment of the area. Finally, a summary of a recent survey of the potential fish resources of the lake is given in the discussion, and estimates of the 1965 catch at the north and south ends of the lake are compared with the findings of the survey. This showed that there is little danger of overfishing the Alestes baremose stocks of the Wanseko area at the 1965 rate of exploitation of the species, and that the total catch for 1965 at the south end of the lake was well below the estimated annual sustainable yield from the area.

Phase transition in polyamide-66/montmorillonite nanocomposites on annealing

The crystalline-phase transition in polyamide-66/montmorillonite nanocomposites before melting was investigated by in situ X-ray diffraction and is reported for the first time in this work. The phase-transition temperature in the nanocomposites was 170 degreesC, 20 degreesC lower than that in polyamide-66. The lower phase-transition temperature of the nanocomposites could be attributed to the gamma-phase-favorable environment caused by silicate layers. Meanwhile, the addition of silicate layers changed the crystal structure of the polyamide-66 matrix and influenced the phase-transition behavior.
