Solar Radiation Enhancement

Tom R.C. Boyde*

Mostly, gardens and greenhouses do not lack for light, but it can happen. This brief note is to introduce an innovative, low-cost means of increasing the intensity of solar radiation when and where it is a serious limiting factor for plant health and growth. Obviously, reflected light can be part of the solution and it has been deliberately so used for well over two hundred years. More recently-published means include providing surfaces that reflect light inwards from outside a greenhouse  or redistribute light within the structure, and another is an elaborate system for illuminating the space under an elevated roadway.

Thermal Properties and X-Ray Diffraction (XRD) Results for Carboxymethyl Cellulose /Polyvinyl Alcohol /Clay Nanocomposite Packaging Films

Behjat Tajeddin*, Najmeh Ramedani

The use of natural polymers is increasing in food packaging applications in order to reduce the consumption of nondegradable synthetic polymer materials. However, due to some poor characteristics of natural polymers, recently, nanotechnology has been employed in various applications like food packaging. Therefore, to use the nanomaterials as a constituent in the packaging material structure, in a research project, the CMC/PVA/nanoclay films were prepared by casting method and their properties were evaluated.

Effects of Amprolium (Anticoccidial) on Some Productive and Reproductive Parameters of Rabbit Doe (Oryctolagus cuniculus)

Ferdinand Ngoula*, GR Kagou Ndonfack, A Kenfack, MM Momo Chongsi, VH Goumtsop A Téguia, P Kamtchouing, J Tchoumboué

This study was designed to study the effects of Amprolium (anticoccidial drug) on some productive and reproductive parameters in female rabbit. For this purpose, 24 nulliparous local breed rabbits, aged 7 months on average were divided into four groups of 6 animals each, and randomized into 24 cages. Amprolium was administered at doses of 0.00, 0.20, 0.32 and 0.80 g/L of drinking water for 8 weeks (4 weeks before and after mating). The average Amprolium intake from the calculated water consumption was 0.00, 32.00, 69.00 and 136.00 mg/kg body weight.

Effects of Impoundment on Land Resources, Population, Agricultural Production and Immigrants Living Environment in the Three Gorges Reservoir, China

Li Ma*, Li-zhong Xia, Lin-zhang Yang, Yun-dong Li

Little information on the influences of impoundment and resettlement on population, agricultural production and farmers living environment in rural areas is available after of the Three Gorges Project (TGP) was built for ten years. Based on the investigation to immigrant households in the areas of head part of the Three Gorges Reservoir (TGR) including Zigui, Xingshan, Badong County and Yiling District, the effects of impoundment on cultivated land resources, population, agricultural production and ecological environment were analyzed in this paper.

Analysis of Genetic Components of Resistance to Ascochyta rabiei in ChickpeaReservoir, China

Mohamed Labdi, Nadira Labdi, Nadia Belhacene, Othmane Merah*

Blight caused by Ascochyta rabiei is one of the most devastating diseases of chickpea that causes yield losses over 80% in some years and may induce total failure to the crop under epidemic conditions. In this study, we tried to understand the role of epidemiological factors of chickpea blight such as incubation and latent periods under greenhouse conditions. A principal component analysis (PCA), hierarchical and multiple regression analyses were performed. The overall analyses of the results revealed that incubation and latent period explain very well the intensity of the disease in the tested lines.

Agro-Geology and CHD in Finland

Timo Toysa*, Osmo Hanninen

Exceptional general and cardiac mortality of eastern Finland has been in focus of international interest, but not entirely explained. In environmental sciences the role of calcium (Ca), magnesium (Mg) and silicon (Si) in coronary heart disease (CHD) has been obscure. We compared CHD with groundwater (gw) Si (Si.gw), and variables associated with Si uptake: soil age, approximated by longitude (Long), temperature (Temp), soil type distribution and soil acidity (pH) in Finnish provinces (N = 11). Soil type proportions we assayed with proportions of coarse and finer mineral soils of cultivated fields (CoMS and FiMS, respectively) and effective cation exchange capacity of soil (CECe). Additionally we assayed soil and timothy (tim) Mg/Ca, gw hardness as (Ca+Mg) and latitude (Lat).
