CONSIDERATIONS ON THE TECHNOLOGIES FOR SEPARATING FRUIT SEEDS WITH APPLICATIONS ON THE SEPARATION OF SEABUCKTHORN PULP FROM SEEDS

Sea-buckthorn is a shrub fruit whose benefits have been known since antiquity. The whole plant is considered medicinal by specialists in the field, but the most active part is the sea-buckthorn fruit because it has a beneficial effect on the entire human body and more recently on animal breeding. A high-value by-product is sea-buckthorn oil, which is currently gaining traders’ attention at international level and which is obtained from both fruit and pomace resulting from the extraction of juice (shells and seeds). This paper presents some representative technolo-gies and installations used for fruit processing in general, technologies that will be the basis for the realization by INMA Bucharest of a technical equipment for separating sea-buckthorn pulp from the seeds

STUDIES AND RESEARCH REGARDING THE UNITARY ENERGY CONSUMPTION OF A RECIRCULATING AQUACOL SYSTEM

This paper aims to highlight the consumption of electricity and caloric energy consumed by a recirculating aquaculture system for the growth of aquatic life. The energy needed to operate a recirculating aquaculture system for fish farming is divided into two categories, namely the electricity needed to operate various technological equipment, the main equipment in a recirculating aquaculture system that uses electricity being recirculation pumps, mechanical filters (some types), UV sterilization facilities and aeration systems. The second category of energy consumed is the caloric energy required for heating / cooling the water in the system and the hall

Auguste Bravard y su contribución al desarrollo de las Ciencias de la Tierra en la Argentina

Contratado por Justo José de Urquiza, llega al país en 1853 el ingeniero francés Pierre Joseph Auguste Bravard, cuya misión era realizar un relevamiento de los recursos minerales. Bravard fue nombrado director del Museo de la Confederación en 1857. Ese mismo año se publican sus “Observaciones geológicas sobre diferentes terrenos de transporte en la hoya del Plata» y, en 1858, la “Monografía de los terrenos marinos terciarios de las cercanías de Paraná». A ellos se agrega un catálogo enumerativo: “Catalogue des especes d’animaux fósiles recueillies dans l’Amerique du Sud de 1852 a 1860” (1860), el “Mapa geológico y topográfico de los alrededores de Bahía Blanca”, y “Estado físico del territorio.

Effect of Leaf Phosphorus and Potassium Concentration on Chlorophyll Meter Reading in Rice

Chlorophyll meter (SPAD) is a convenient tool to estimate leaf nitrogen (N) concentration of rice plants. There is no information on the effects of leaf phosphorus (P) and potassium (K) concentration on SP AD readings and on the relationship between SPAD values and leaf N concentration in the literature. In 1996 dry season, cv IR72 was grown at the International Rice Research Institute (IRRI) and the Philippine Rice Research Institute (PhilRice) under various N, P and K fertilizer combinations. SPAD measurements were made on the topmost fully expanded leaves at mid-tillering and panicle initiation. The leaves were then detached, dried and analyzed for N, P and K. The SPAD values were highly correlated with leaf N concentration (r = 0.93 to 0.96). Fertilizer-K application did not affect SP AD values, leaf N concentration, or the relationship between the two. Phosphorus deficiency reduced leaf N concentration at mid-tillering, but increased leaf N concentration at panicle initiation when the same amount of N was applied. The SPAD values were 1 to 2 units greater for zero-P plants than P-treated plants at a given leaf N concentration at mid-tillering. At panicle initiation, the relationship between SPAD values and leaf N concentration was not significantly affected by leaf P status. These results suggest that a different regression equation between SP AD values and leaf N concentration should be used to estimate leaf N concentration of P-deficient and P-sufficient rice leaves at vegetative stage using a SPAD

GENERAL ASPECTS REGARDING THE GROWTH FRESHWATER FISH IN CUBES, AN ALTERNATIVE FOR AQUACULTURE IN ROMANIA

Due to the increased consumption of fish, as an alternative to achieving healthy population nutrition, the development of European aquaculture also shows an increasing trend. At present, freshwater culture is about 42% of total European fish production. Valuable species, from an economic point of view, can be reared in intensive systems in cages on running waters or ponds, combined with less valuable species. There are also new species that are gradually becoming increasingly important for the fish industry in Europe. Freshwater aquaculture in Romania is based on rainbow trout and carp which are still predominant species, but there is significant demand for valuable fish species [11,12,16]. Â

Rice yields decline with higher night temperature from global warming

The impact of projected global warming on crop yields has been evaluated by indirect methods using simulation models. Direct studies on the effects of observed climate change on crop growth and yield could provide more accurate information for assessing the impact of climate change on crop production. We analyzed weather data at the International Rice Research Institute Farm from 1979 to 2003 to examine temperature trends and the relationship between rice yield and temperature by using data from irrigated field experiments conducted at the International Rice Research Institute Farm from 1992 to 2003. Here we report that annual mean maximum and minimum temperatures have increased by 0.35°C and 1.13°C, respectively, for the period 1979–2003 and a close linkage between rice grain yield and mean minimum temperature during the dry cropping season (January to April). Grain yield declined by 10% for each 1°C increase in growing-season minimum temperature in the dry season, whereas the effect of maximum temperature on crop yield was insignificant. This report provides a direct evidence of decreased rice yields from increased nighttime temperature associated with global warming

Costochondral graft with green-stick fracture used in reconstruction of the mandibular condyle : experience in 13 clinical cases

Since its publication in 1920 by Gillies, costochondral grafts have been used by surgeons to replace an injured mandibular condyle and to reconstruct the temporomandibular joint. This procedure is currently applied in cases of congenital dysplasia, developmental defects, temporomandibular ankylosis, neoplastic disease, osteoarthritis and post-traumatic dysfunction. Over the years, various procedures for the reconstruction with this type of graft have been described. In 1989, Mosby and Hiatt described a technique for setting the graft securely, reducing the space between the graft and the mandibular area. In 1998, Monje and Martín-Granizo developed a variation of this method, enabling a precise adaptation of the costochondral graft to the remaining mandibular ramus. The aim of this study is to evaluate the functional and anatomic results of the costochondral graft treatment by green-stick fracture for reconstruction of the TMJ in the 10 years following the description of this technique. We carry out a retrospective study of thirteen cases of temporomandibular pathology (tumors, ankylosis and hypoplasia) treated during a period of ten years from 1998 to 2008. In all these cases, the technique described by Monje and MartínGranizo was used: removal of the sixth rib, fixation to a titanium mini-plate using screws, making an internal corticotomy in order to obtain a green-stick fracture of the outer cortex, providing adequate adaptation of the graft to the mandibular ramus. The graft was then set in place, attaching it with titanium screws. This technique was successful in achieving optimal ossification, a good interincisal opening and satisfactory cosmetic results. In conclusion, according to our experience, the green-stick fracture for the adaptation of costochondral grafts to the remaining mandibular ramus has presented outstanding results in the surgical treatment of temporomandibular pathology
