Opis:
Zinc oxide thin films was deposited by chemical spray pyrolysis (CSP) at 400 °C substrate temperature and different thickness (60, 80, and 100) nm on the texturized p-Si wafer to fabricate ZnO/p-Si heterojunction solar cell. Structural, optical, electrical and photovoltaic properties are investigated for the samples. XRD analysis reveals that all the as deposited ZnO films show polycrystalline structure, without any change due to increase of thickness. Average diameter calculated from AFM images shows an increase in its value with increasing thickness, ranging from 59.82-95.7 nm. The optical reflections for samples are measured using UV-Vis spectrophotometer. Photoluminescence (PL) spectra of (CSP) grown ZnO/p-Si with different thickness were used to study the energy gap. The electrical properties of heterojunction were obtained by I-V (dark and illuminated) and C-V measurement. I-V characteristic of the ZnO/p-Si heterojunction shows good rectifying behavior under dark condition. The ideality factor and the saturation current density was calculated. Under illuminated the photovoltaic measurements (open-circuit voltage (Voc), short-circuit current density (JSC), fill factor (FF), and quantum efficiencies are calculated for all samples. The built- in potential (Vbi), carrier concentration and depletion width are determined under different thickness from C-V measurement.

This work involves synthesis of activated carbon from Iraqi date palm seeds as agricultural wastes using kehdrawy palm seeds. The preparation was conducted by chemical activation method using ZnCl2 as an activator. The synthesized activated carbon (AC) was characterized by different analytical and spectroscopic methods. This involves using scanning electron microscopy (SEM), flourier transformation infrared (FTIR), ash content, adsorption capacity, the percentage of humidity and the point zero charge (PZC). The activity of the prepared activated carbon was investigated by following the removal of reactive yellow 145 dye (RY 145) from the aqueous solutions. For a comparison a sample of non- activated carbon (NAC) was used in the same process. From the obtained results it was found that AC was more efficient in dye removal in comparison with NAC under the same conditions

Opis:
A field experiment was conducted from June to March in years 2013/2014 and 2014/2015 at the Research Farm, University of Agriculture, Makurdi, Nigeria, to evaluate the yield response of cassava-okra intercrop as influenced by population densities and time of introducing okra, as well as assessing the yield advantages of the intercropping system. The experiment was a 3 x 3 factorial combination of treatments, fitted in a randomized complete block design, with four replications. The population densities of okra (33,333, 40,000 and 50,000 plants ha-1 equivalent) into cassava constituted the main plots, while the time of introducing okra into cassava (okra sown at the same time with cassava in mid June; okra introduced into cassava in mid July and okra introduced into cassava in mid August) were assigned to the subplots. Results of study showed that sowing okra at the same time as cassava in mid June, at the population density of 33,333 plants ha-1 produced the highest yields of cassava (46.8 t ha-1 and 39.2 t ha-1 respectively in years 2013 and 2014) and okra (7.7 t ha-1 and 7.5 t ha-1 respectively in years 2013 and 2014) in a cassava-okra intercrop. This level of interaction also gave the highest total intercrop yields, highest land equivalent coefficient (LEC) values, highest land equivalent ratio (LER) values of 1.86 and 1.84 and highest percentage (%) land saved (46.2 % and 45.7 %) respectively recorded in years 2013 and 2014. The implication of study showed that it is most advantageous having both crops in intercrop when okra was sown at the same time as cassava in mid June, at the population density of 33,000 plants ha-1. This should therefore be recommended for Makurdi location, Nigeria.

The study was conducted at Akpehe poultry farm, Makurdi. The objectives of the study were to assess the additive genetic effects of dam-sire, dam and maternal effects on clutch traits with the aim to apply these to selection and breeding in order to improve these traits.120 birds were used for the study, 60 each for the Fulani and the Tiv ecotypes. The birds were housed singly in identified cages and hand mated in the pen. Data were collected on clutch size, clutch number, pause length and number, month, sire, dam and ecotype. Ecotype significantly affected clutch size and clutch number. Pause length and number were not affected by ecotype. The additive genetic effect of the sire and dam significantly affected clutch size and clutch number. Heritability estimates due to sire on pulse length and pulse number were very low, while the heritability estimates for clutch number and clutch size were moderate. Non additive genetic effect of the dam ,other maternal environment as well as month significantly affected clutch number, pause length and number. Selecting superior birds based on clutch size and number due moderate heritability estimates will lead to genetic improvement in egg number especially when dam conditions and management employed are improved.

Opis:
The solar flares are generated from electromagnetic radiation which is sudden oscillation of the stored energy in the magnetic field of the sun. Flares are categorized according to their brightness as C, M and X, where X is the brightest. The X class flares caused a long-time solar storm and ionospheric radio waves sparkling. The moderate level M class flares mostly effect polar cups and cause short-time radio sparkling. However, the C class flares are weaker than the X and M flares. In this work, we present an active region from the disturbance of magnetic field on the area of the Sun and may lead to powerful event if the magnetic field become stronger. The CALLISTO system network that has been installed in Gauri, India observed data that contain Solar Radio Burst Type II (SRBT II) occurred on 22nd December 2009 at 04:57 UT to 05:02 UT. Five active regions were obtained from online data via internet from the Space Weather website and the Solar Monitor website. All data and information from these sources assist in analyze of the phenomena. The magnetic field and X-ray flux, proton density increase the possibilities that SRBT II observed by CALLISTO network to generate powerful solar flare. When X-ray flux level was at maximum, then solar flare was at peak point. However, solar activity level was low because among of five active regions present, only one C-class flare event occurred. The most active region that contributes this event is an AR11036 with C-class flare.

Opis:
During 13th of May 2015, the solar wind is very high velocity, which is 733 kms-1 as compared to 367.5 kms-1. It is believed that the plasma–magnetic field interactions in the solar corona can produce suprathermal electron populations over periods from tens of minutes to several hours, and the interactions of wave-particle and wave-wave lead to characteristic fine structures of the emission. An intense and broad solar radio burst type II was recorded by CALLISTO spectrometer from 20-85 MHz. Using data from a the Blein observatory, the complex structure of solar burst type III can also be found in the early stage of the formation of type III solar burst type event due to active region AR 12339. The drift rate of solar burst type III exceeds 1.0 MHz/s with 6.318 x1012 e/m3 a density of electron in the solar corona. There were also 2 groups of solar radio burst type III were observed. This CME was detected at 08:36 UT which is 1and ½ hour after the solar burst detected. This event shows a strong radiation in radio region, but not in X-ray region.

Opis:
The advent of British Colonial rule in Nigeria transformed the traditional African society in a number of ways, some positive others negative. The initial policies adopted to integrate Nigerian into the British colonial system, however, proved a catalyst that triggered mass movement of people from rural to urban centers thereby creating as it were unexpected demographic dislocation. British development of communication and infrastructures such as railways and the network of road system was part of a deliberate policy to foster the growth of “legitimate trade” in the interior. The early imposition of tax regime in the Northern Protectorate induced people from the zone of taxation to migrate to tax free zones. The combination of abiding peace, agricultural export and modern communication system stimulated migration during British colonial administration in Nigeria. It is the conviction of the author that establishment of British rule had fundamental far-reaching effect on inter-ethnic mingling and migration. The paper examines the various policies of the British at the onset of colonial rule and the effect of these on inter-ethnic migration and mingling. Attempt is made to briefly define the two key words, migration and colonialism, in order to give better understanding to the work. The paper concludes that British colonial policies had profound effect on the people’s decision to leave home and migrate to zones of administrative and economic activities.

This Radio Frequency Interference (RFI) study is currently one of a main sub-research in radio astronomy in Malaysia. The main objective of this monitoring is to test and qualify the potential of radio astronomical sources that can be observed in Malaysia generally. Analysis process focuses at indoor and outdoor of Faculty of Applied Sciences, UITM Shah ALAM, Malaysia (latitude: 03°06.534’N, longitude: 101°50.396’E). There are three mobile network communications that operate at the upper band frequency of 1800MHz, which are Maxis (1805-1830 MHz), Celcom (1830-1855 MHz) and Digi (1855-1880 MHz) for GSM/LTE network. We observed that both sites having the highest and second highest peak at the same frequency of 420 MHz and 1835 MHz with the same source, which were due to mobile application followed by the lowest peak due to radio navigation satellite. We verified that the source of RFI of 1835 MHz at the Faculty of Applied Sciences may come from Celcom mobile telecommunication network signal because there is transmitter on top of two Celcom towers. This observation must be continuously done to ensure that RFI level does not increase drastically and to ensure that allocation spectrum band that was reserved for radio astronomy activities was always protected.

Corn stands at the center of Mankind, providing Humanity with raw materials for further survival and development. As the need for corn doubles, and as science further widens knowledge on the use/utilization of the crop, creating more avenue and approaches where corn grains, leaves, silk, stem, root and other parts of the plant can be transformed into countless products, then the need to devote more hectares of land to Corn production becomes imperative. Corn has been shown to have the potential to be used in combating global food insecurity, as an indicator-crop for soil fertility assessment and as a commercial cash crop for income generation. Production of Corn has reduce poverty rate and raise standard of living of farmers, especially in the poor/developing countries.

A ten-week experiment using twenty four (24) weaner rabbits (Chinchila x New Zealand White) aged 8 to 9 weeks with an average initial body weight of 431.20+0.74g were randomly allocated to four treatment diets of T1(control), T2(5% NLM), T3(10% NLM) and T4(15% NLM) in a completely randomized design. They were fed for 10 weeks during which data on growth and haematology were collected and analysed using analysis of variance (ANOVA) and means separated using Duncan Multiple Range Test. The results showed that the average total body weight gains were 739.60g (T1), 717.85g (T2), 740.18g (T3) and 729.45g (T4).There was no significant difference (p>0.05) when T1 and T3 as well as T2 and T4 were compared but significant (p<0.05) when T1 and T2 as well as T3 and T4 were compared. Also the average weekly feed intake showed that T1, T2, T3 and T4 consumed 313.91g, 313.24g, 312.48g and 314.69g respectively. However, there was significant difference (p<0.05) when all the treatments were compared in this respect. The feed conversion ratio (FCR) showed that T3 (4.22) was the best followed by T1 (4.24), T4 (4.31) and T2(4.36) with significant differences (p<0.05) among them except (p>0.05) between T1 and T3. The haematological indices showed that though all the parameters fell within the normal physiologic ranges, the PCV was 37.62% (T1), 38.42% (T2), 39.60% (T3) and 39.03% (T4) and when compared, were all significantly different (p<0.05) except (P>0.05) for T3 and T4 while the haemoglobin concentration showed that T1(13.47g/dl) was significantly different (p<0.05) from T2(14.18g/dl), T3(14.34g/dl), and T4(13.97g/dl). The white blood cell count showed that T3 (10.62 x109/L) had the highest value followed by T1 (10.12 x109/L), T4 (9.34 x109/L) and T2 (9.18 x109/L) with a significant difference (p<0.05) occurring when T1 and T3 were compared to T2 and T4 while the red blood cell counts indicated that T1 had the highest value of 4.92 x106/L followed by T3(4.89 x106/L), T2(4.73 x106/L) and T4(4.65 x106/L) without any significant difference among the treatments. All the values fell within the normal range. It is therefore recommended that inclusion of neem leaf meal in the diets of rabbits up to 10% is not detrimental since it improved feed conversion ratio (FCR), growth performance and had no negative effect on haematological values.

The effect of plant population on the growth and yield Mucuna flagellipes (Vogel ex Hook) was conducted for two cropping seasons (2013 and 2014) in the Teaching and Research farm, Department of Agronomy, Cross River University of Technology Obubra, Cross River State. The experimentwas laid out in a randomized complete block design (RCBD). Treatments comprised four plant populations of 33,333, 16,666, 10,000 and 8,333 plants/ha and there were three replications. Data collected were statistically analyzed using Analysis of Variance (ANOVA) procedure for a randomized complete block design. Close spacing with high plant population significantly (p < 0.05) reduced the number of leaves, branches and dry matter of plant fractions per plant.
