Andiroba (Carapa Procera Aubl) belongs to the Meliaceae family and is a plant of great importance for the traditional medicine in the Amazon. Also, the oil obtained from its seeds is widely used in the cosmetics industry. The following study was carried out at the Tropical Silviculture Experimental Station of the National Institute of Amazon Research (EEST/INPA), where the growth of andiroba seedlings was evaluated using three types of substrates which received daily irrigation, according to...

Single cell protein SCP also referred as microbial protein is defined as protein derived from cells of microorganisms such as yeast, fungi, algae, and bacteria, which are grown on various carbon sources for synthesis. The dried cells of microorganisms or the whole organism is harvested and consumed. In this work SCP was produced from different agricultural waste substrates like food and vegetable waste, rice husk, pulses husk, bagasse and wheat straw using Aspergillus niger. These substrates...

Year 2000 has been an active one for large-scale propulsion testing at the NASA John C. Stennis Space Center. This paper highlights several of the current-year test programs conducted at the Stennis Space Center (SSC) including the X-33 Aerospike Engine, Ultra Low Cost Engine (ULCE) program, and the Hybrid Sounding Rocket (HYSR) program. Future directions in propulsion test are also introduced including the development of a large-scale Rocket Based Combined Cycle (RBCC) test facility.

With the aim of improving the growth of plants of Aloe barbadensis and A. arborescens and improve the content of sugars and minerals, several experiments were conducted replacing chabazitic-zeolites with normal inorganic substrates and adding the effective microorganisms (EM) to assess whether they affected plant development. The experiment on both Aloe species involved three treatments: 1) soil; 2) soil with addition of chabazitic-zeolites; and 3) soil with addition of chabazitic-zeolites...

Since the advent of meteorological satellites in the 1960's, numerous experiments have been conducted in order to evaluate the impact of these and other data on atmospheric analysis and prediction. Such studies have included both OSE'S and OSSE's. The OSE's were conducted to evaluate the impact of specific observations or classes of observations on analyses and forecasts.

In this study, we aim to understand how S. shibatae copes with high temperatures. In particular, we investigated the role of the 60 kDa heat shock protein (HSP60 or chaperonin) with the hypothesis that chaperonin stabilizes the cell membrane under stressful conditions. To prove the hypothesis, this year two questions were addressed: (1) Is the chaperonin localized in the cytoplasm or on the cell membrane (2) Does the chaperonin show affinity to lipid in vivo In addition to those, we intensively...

We describe the design of a new type of two-stage pulsed electromagnetic accelerator, the gallium electromagnetic (GEM) thruster. A schematic illustration of the GEM thruster concept is given. In this concept, liquid gallium propellant is pumped into the first stage through a porous metal electrode using an electromagnetic pump. At a designated time, a pulsed discharge (approx. 10-50 J) is initiated in the first stage, ablating the liquid gallium from the porous electrode surface and ejecting a...

The perpendicular and parallel multilayer relaxations of fcc (210) surfaces are studied using equivalent crystal theory (ECT). A comparison with experimental and theoretical results is made for AI(210). The effect of uncertainties in the input parameters on the magnitudes and ordering of surface relaxations for this semiempirical method is estimated. A new measure of surface roughness is proposed. Predictions for the multilayer relaxations and surface energies of the (210) face of Cu and Ni are...

Aerodynamic calibration and physical measurement have shown that the flexible steel plates which form two walls of the throat and test section of the 1- by 3-foot supersonic wind tunnels have surface irregularities of great enough magnitude to cause sizable flow disturbances. Since some of the surface irregularities are as large as 0.020 inch, it was felt that simply remachining the 0.250-inch-thick steel plates would not be advisable for several reasons, one reason being that thinning the...

Recently substantial progress has been made towards design building and testifying remotely piloted Micro Air Vehicles (MAVs). This progress in overcoming the aerodynamic obstacles to flight at very small scales has, unfortunately, not been matched by similar progress in autonomous MAV flight. Thus, we propose a robust, vision-based horizon detection algorithm as the first step towards autonomous MAVs. In this paper, we first motivate the use of computer vision for the horizon detection task by...

Cooling flows in clusters of galaxies occur when the cooling time of the gas is shorter than the age of the cluster; material cools and falls to the center of the cluster potential. Evidence for short X-ray cooling times comes from imaging studies of clusters and X-ray spectroscopy of a few bright clusters. Because the mass accretion rate can be high (a few 100 solar mass units/year) the mass of material accumulated over the lifetime of a cluster can be as high as 10(exp 12) solar mass units....

Application of the logic of inference to this set of assertions allows one to derive the logic of inquiry among questions. There are interesting symmetries between the logics of inference and inquiry; where probability describes the degree to which a premise implies an assertion, there exists an analogous quantity that describes the bearing or relevance that a question has on an outstanding issue....

Theory of near-field thermal coupling between a nanocarbon material and various substrates was derived. Models were developed to cover a range of nanocarbon dimensions (1D, 0D and 2D), from nanotube films to forests and to graphene layers. A broad range of semiconductor, insulator and metal substrate materials was numerically studied. Materials parameters for optimization of QED Kapitza conductance were determined, including: optimal distance which in turn depends on the frequency of the...
