In this research we are Studying the improvement of the thermal
conductivity of The 6063 aluminum alloys by Alloy elements
Adding such as (Boron & Titanium) .
In this Study we used (6063) aluminum alloy as a base metal
because it using of the fab
rication of Central Processing Unit(CPU)
heat sinks . First, we brought casting mold. We melted Aluminum
after weighting it ,and we adding Alloy elements (Boron &
Titanium), we selected the temperatures of the furnace at 1000 ℃
,for period 60 minute.
the experiment was conducted under Syrian coastal conditions to investigate (Vicia
fabaL.), the effect of boron and zinc foliar fertilization on faba bean,either individually or
in combination, by increased rates (0, 0.25, 0.50, 0.75, and 1 kg boro
n / has boric acid, and
zinc at a rate of 0, 0.375, 0.750, 1.125, and 1.5 kg / ha as zinc sulfate). where fababeans
were plantedin plastic pots(15L) in )2013/11/10(and )2014/11/10(.The soil in pots has high
content of calcium carbonate, low boron and zinc content, with pH slightly basic
(representative of the region's soils).
Half boron and zinc fertilizer rates were sprayed after 33 days of germination and the
other half ,after 65 days of germination. The results showed significant responses in all
studied parameters (number of branches,number of pods / plant, weight of 100 seeds, and
seed yield (Kg. / ha) on faba bean plant, as a result of foliar fertilization by boron and zinc.
Fababeans response to boron is higher than to zinc fertilization in all studied
indicators. However,the treatmentB75Zn75(0.75 kg boric acid and 1.125kg of zinc sulfate)
is the best, as compared to others. Also, the driedseeds yield was increased by about
17.66%.
Strawberry plants of Oso Grande variety has been treated with three types
of foliar fertilizers containing (Nitrogen, Boron, Manganese) individually and
combined, in addition to treating some of them using urea as soil fertilizer.
Some plants were untreated to be used as a control. Three concentrations were
used.
