α- Zirconium Titanium Phosphates - Fibrous Cerium Phosphate Composite Membranes and Their 1,10- Phenanthroline Cu(II) Pillared Materials

Abstract Nanosized fibrous cerium phosphate, Ce(HPO4)2.2.9H2O(nCePf), and α- Zirconium -Titanium Phosphates, ZrxTi1-x(HPO4)2.H2O(α-ZTP), where x = 0.9, 0.8, 0. 67, 0.34, were synthesized. Novel composite membranes [ZrxTi(1-x)(HPO4)2]0.25 [Ce(HPO4)2]0.75 .3.3H2O were prepared. Reactions of the resulting composite membranes with 1,10-phenanthroline in ethanol, followed by the addition of 0.1M CuCl2.2H2O, in (1:1) ethanol: aqueous solution, lead to the formation of novel pillared materials: [(H1.16) Zr0.9Ti0.1 (PO4)2]0.25[(H1.16 ) Ce (PO4)2]0.75(PhenCu)0.42.2.25H2O, [(H1.5)Zr0.8Ti0.2 (PO4)2]0.25 [( H1.5)Ce (PO4)2] 0.75 (Phen Cu)0.25.1.77H2O, [(H0.3 ) Zr0.67Ti (PO4)2] 0.25 [(H 0.3) Ce (PO4)2]0.75.(Phen Cu)0.85. 4H2O, [(H1.6)Zr0.34Ti0.66 (PO4)2]0.25 [(H1.6) Ce (PO4)2]0.75.(PhenCu)0.2. 2.22 H2O, respectively. They were characterized by chemical, X-ray diffraction (XRD) and thermal analysis (TGA), accordingly were formulated. XRD patterns of the composite materials retain (d) spacing reflection of α-ZTP and nCePf, where d001 = 7.58 Å and 11.38 Å, respectively, The resulting composites are thermally stable and can be considered as novel ecofriendly solid acid catalysts, Ionex changers and ionc conductance materials

Optimization of Central Patterns Generators (CPGs)

The issue of how best to optimize Central Patterns Generators (CPG) for locomotion to generate motion for one leg with two degrees of freedom has inspired many researchers to explore the ways in which rhythmic patterns obtained by genetic algorithms may be utilized in uncoupled, unidirectional and bidirectional two CPGs. This paper takes as its assumption that the focus on stability analysis to decrease variation between steps brings about better results with respect to the gait locomotion, and argues that controlling the amplitude and frequency may lead to more robust results viz., stimulation for movement

Livestock Hydatid Disease (Cystic Hydatidosis) in Libya: A Review (2016). Mostafa M. Abdorrahem and Kawther M. Ibrahem Mohamed M. Ibrahem, Wafa M. Ibrahem. American Journal of Animal and Veterinary Sciences 11 (2), 70-84

Cystic hydatid disease is an infection caused by the larval stage of a cestode parasite called Echinococcus granulosus. Hydatid cysts are one of the major parasitic infections in Libya that causes many health problems to human and responsible for economic losses because of the condemnation of the slaughtered animals infected viscera as well as reducing the quality and quantity of the livestock other productions such as milk, wool and meat. Many abattoir investigations in Libya have revealed that, cystic hydatidosis is a disease which infect a wide range of animal species with variable rates of infection, for example, sheep (1.6 to 40%), goats (5.6 to 70%), cattle (2.7 to 56%) and camels (2.7 to 48%). Based on the available abattoirs data, cystic echinococcosis in livestock can be classified as hyper endemic in the country as the infection rate in all animal species reached almost 50% or over which fulfill the WHO criteria. Because of the absence of accurate and updated government records in all abattoirs, it is difficult to estimate the exact economic losses due to cystic hydatidosis in livestock. Diagnosis of the parasite larval stage (hydatid disease) in the living intermediate hosts (ante mortem) is basically by using imaging and serological methods, while after slaughtering the animals (post mortem), the examination of hydatid cysts can be by inspection of several expected infected organs mainly liver and lungs and to some extent other organs including spleen, kidneys, heart, brain and bones of the animal carcasses. Prevention of cystic hydatid disease primarily focusing on veterinary investigations for controlling the extent and the intensity of echinococcosis in the definitive host populations, which indirectly may lead to control the prevalence of hydatid disease in the intermediate host animals. Treatment of cystic hydatidosis in livestock is still under investigation but anti-helminthes drugs can be used. Regular treatment, taking high degree of precautions when handling pets or dealing with animal meat must be taken into consideration to minimize the level of infection and egg excretion as well as the vaccination of ruminant intermediate hosts, are all in evaluation.
