Expressions with an aspectual variant of a light verb, e.g. take on debt' vs. have debt', are frequent in texts but often difficult to classify between verbal idioms, light verb constructions or compositional phrases. We investigate the properties of
such expressions with a disputed membership and propose a selection of features that determine more satisfactory boundaries between the three categories in this zone, assigning the expressions to one of them.
The paper reports on a corpus study of German light verb constructions (LVCs). LVCs come in families which exemplify systematic interpretation patterns. The paper's aim is to account for the properties determining these patterns on the basis of a corpus study on German LVCs of the type stehen unter' NP' (stand under NP').
In this research we have studied the absorbance of some zinc alloys. These alloys were
manufactured in the local market, and these alloys can be used as absorber plate in the
manufacture of solar collectors. We conducted this study in the laborator
y, first (using
tow light sources, 100W and 30 W), and Second in the external medium using direct solar
radiation. Our research provides important information that could be used in improving the
efficiency of solar collectors using absorbent surfaces that has a higher absorbency.
We have also studied the relationship between the absorbance and the atomic number of
the studied alloys. This study showed that the absorbed energy by these metals increase
with their atomic laboratory number Z.
This study was performed in order to determine the temperature
rise under human dentin discs of different thicknesses of primary teeth
during the light curing process with conventional halogen lamp and
LED.
The purpose of this research to control LED Lamps lightintensitydependent ofoutside
light intensity using electronic board Arduino Uno. control LED lamps analog voltage
achieved by pulse width modulation (PWM) digitally, studying LDR sensorspecific
ation,
designing light meter after founding the relationship between light dependent resistance
and light intensity measured by Lux,constructing a program using Arduino IDE for
microcontroller onArduino Uno that will maintain the desired light intensity selected.
Testing finally all the circuits after it has been completed circuit design and data are
collected. proving that it is possible to maintain the desired intensity of light and calculated
the average power consumption taking into consideration heat loss of LED lamps for 12
hours for tow values of light intensities 200,300 lux with outside light intensity and heights
1m and 1.5 m.It found that when the outside light intensity increases thecurrent intensityis
decreasing through LED lamps automatically and reduce power consumption. Thus, it can
be concluded using this board that it conserves energy.
The present study aimed to assess the influence of curing
distance on the loss of irradiance and power density of two curing
light devices of two different systems.
Two dental curing devices were used in this study,
Halogen unite (Chromalux 75) and light emitting diodes (LED)
(Bluedent smart),
In this work, the UV-Visible photolysis aqueous ferrioxalate
complexes has been studied kinetically and
mechanistically, in the absence and presence of molecular oxygen.
Species of the genus Campylobacterare recognized as the main cause of foodborne disease in both developing and developed countries. They are main causative of diarrhea and gastroenteritis worldwide. Staphylococcus bacteria especially S. aureus are re
sponsible of food poisoning due to their ability to produce enterotoxins.
Traditional methods which are used to identify bacteria are time-consuming and labor intensive and very expensive.
Thirteen isolates of Campylobacter and twenty-two isolates of Staphylococcus were isolated from a variety of foods. Traditional methods based on biochemical tests were used for identification in addition to laser light-scattering technique to discriminate isolates.
Laser light-scattering technique showed the ability to distinguish all isolate in high accuracy, rapid and low costs manner, thus it may represent a potential alternative to traditional methods to identify these bacteria.
So it is a very important issue to find new alternative methods characterized by high accuracy, low costs and rapidity in results achievement, to replace traditional methods, thus laser light-scattering may be a possible alternative
The effect of the reversible photo-orientation of the Solvent Red 23 dye
incorporated in Poly (methyl methacrylate) thin films has been investigated. A
probe-pump optical system was used to investigate the dichroic behavior of the
samples. Orthogo
nal polarized laser light induces a smaller increase in the
transmitted beam intensity. A stronger polar order was induced using a
parallel pump-probe laser light compared to that of the perpendicular state. It
was found that the dichroic ratio value of the Poly (methyl methacrylate) /
Solvent Red 23 thin film is 4.952, which indicates that the net orientation of
Solvent Red 23 molecules is orthogonal to the applied beam field. The dynamic
evolution of the dichroic ratio showed that the relaxation is rather slow, and it
deteriorates in a slow logarithmic fashion, which may take a very long time in
order to reach the isotropic state.
Effect of different degrees of temperature, different levels of pH , different periods of
light and four media (PDA, OMA, MEA, CzA) was studied in vitro against the growth of
C. gloeosporioides causing anthracnose disease of citrus fruits. The resu
lts indicated that
the growth of fungus was maximum at temperature 30°C and at pH = (5.5,6,6.5), and Light
was unnecessary for the growth of C. gloeosporioides. Among the different media tested
PDA and OMA supported the maximum growth of fungus.
