Comparative Effects of Drip and Furrow Irrigation with Saline Water on the Yield and Water Use Efficiency of Potato (Solanum tuberosum L.) in Arid Conditions of Tunisia
K. Nagaz,I. Toumi,M.M. Masmoudi,N.B. Mechlia
Agricultural Journal , 2013,
Abstract: Field experiment was conducted on a sandy soil during spring of 2005 in southern Tunisia for evaluating the effects of drip and furrow irrigation methods on soil salinity, yield and water use efficiency of potato (Solanum tuberosum L.). For both irrigation methods, irrigations were scheduled when readily available water in the root zone (35% of the total available water) was depleted. Well water with an ECi of 3.25 dS m 1 was used for irrigation. Growth, yield, yield components, water supply and soil salinity were measured. Results show that higher soil salinity was maintained in the root zone with furrow than drip irrigation. The growth and yield of potato irrigated through furrows were significantly lower when compared with drip irrigation. Potato yield was increased 11% relative to that for furrow irrigated potato. Under drip irrigation, 20.8% of the irrigation water was saved in comparison with furrow irrigated potato; and irrigation water use efficiency increased by 29% compared with that of furrow irrigation. Drip irrigation method provides significant advantage on yield and WUE, compared to furrow irrigation in potato production under experimental conditions. Therefore, the drip irrigation method is recommended to optimize the use of saline water in potato production under the arid mediterranean conditions of southern Tunisia.

Aflatoxin B1 contamination in papaya fruits (Carica papaya L.) during post harvest pathogenesis
Indian Phytopathology , 2011,
Abstract: An investigation on post-harvest diseases of papaya fruits at Udgir fruit market showed association of nine fungi. These nine fungi were isolated from papaya fruits showing rotting symptoms that are displayed for sale in retail shops. The fungi isolated from decayed papaya fruits were: Gloeosporium papaya, Fusarium solani, F. moniliforme, Rhizopus stolonifer, R. nigricans, Botrydiplodia theobromae, Curvularia lunata, Aspergillus flavus, and A. niger. All these fungi were found to be highly pathogenic leading to rapid deterioration of papaya fruits. A detailed investigation was carried out only on Aspergillus flavus producing aflatoxin B1. Fifteen isolates of Aspergillus flavus obtained from decayed papaya fruits were screened for aflatoxin B1 production in naturally spoiled and artificially inoculated fruits. Nine isolates were found to produce aflatoxin B1 in naturally spoiled as well as in artificially inoculated fruits. Aflatoxin B1 produced by these isolates in naturally spoiled fruits ranged from 97.5 to 553.1μg/kg of fruit pulp, while aflatoxin B1 production by these nine toxigenic isolates in artificially inoculated fruits ranged from 37.3 to 613.1μg/ kg of fruit pulp. Results of this investigation lead to two important points: firstly, nine fungi found to be associated with post-harvest rots of papaya fruits and had many fold effects on fruits nutritional value; secondly the quantity of aflatoxin B1 produced by Aspergillus flavus isolates was very high, which is a great concern to the health of consumers.

Spin models of quasi-1D quantum ferrimagnets with competing interactions
N.B. Ivanov
Condensed Matter Physics , 2009,
Abstract: We present a brief survey of the recent theoretical work related to generic Heisenberg spin models describing quasi-one-dimensional quantum ferrimagnets. The emphasis is on quantum chains and ladders with strong competing interactions, such as the frustrated J1-J2 chain with alternating (1, 1/2) spins, the spin-1/2 diamond chain with four-spin cyclic couplings, and some generic types of mixed-spin ladders with geometric frustration. As a rule, the discussed models exhibit rich quantum phase diagrams and provide some interesting examples of one-dimensional magnetic-paramagnetic quantum phase transitions. A number of open problems in the reviewed research area are discussed.

Abstract: Progeria is a progressive disorder that causes children to age rapidly beginning in two years of life. The children with Progeria also known as Hutchinson - Gilfold Progeria Syndrome (HGPS) generally appear normal at birth. Progeria was first described in an academic journal by Dr. Jonathan Hutchinson in 1886, and Dr. Hastings Gilfold in 1897 - both in England. It is a rare disorder with a reported incidence of one in 8 millions births. It occurs sporadically and is believed to follow an autosomal recessive inheritance. Progeria signs include growth failure, loss of body fat and hair, aged - looking skin, stiffness of joints, hip dislocation, generalized atherosclerosis, cardiovascular disease and stroke. This review summarizes the clinical characteristics and the underlying mutation in the Lamin A gene, diagnostic methods and management and future directions of this disease.

Abstract: There is described a case of correction of skeletal forms of malocclusions with an orthodontist and orthognathic surgeon participation. The observation emphasizes the necessity of team approach to solve esthetic and functional defects in dentition in marked forms of pathological occlusions.
Combining Ability and Heritability of Callus Induction and Green-Plant Regeneration in Rice Anther Culture
N. Bagheri,N.B. Jelodar
Biotechnology , 2008,
Abstract: This study was conducted to determine the inheritance of callus induction and plant regeneration in rice anther culture. Low efficiencies of callus induction and green-plant regeneration have limited the application of anther culture in plant breeding programs. Four parents along with six F1 genotypes derived from a four-parent incomplete diallel mating set of two commercial lines (Amol2 and Amol3) and two local cultivars (Ghasroddashti and Rashti) were evaluated for their callus induction and plant regeneration abilities. The results showed that the callus induction, green-plant regeneration and the effects of genotype and genotypexmedium interaction were significant (p<0.01). The local cultivars generally had a higher percent callus induction, plant regeneration and number of calli producing green plants than the commercial lines. The parents showed significant difference in anther callus formation, from 4.01% (Amol2) to 22.26% (Rashti). Combining ability analysis demonstrated the predominance of additive gene effects in the control of both characters with the local cultivars having higher combining ability for green-plant regeneration. Also gene action to be partially dominant for both characters. Combining ability analysis revealed that both additive and dominant gene effects are important in controlling callus induction and green-plant regeneration in rice.

Journal of the Brazilian Society of Mechanical Sciences and Engineering , 2009, DOI: 10.1590/S1678-58782009000100004
Abstract: in this paper, a theoretical analysis of the effects of couple stresses on the squeeze film lubrication between circular stepped plates is presented. modified reynolds type equation is derived for the couplestress fluids. closed form solution is obtained. according to the results obtained, the influence of couple stresses enhances the squeeze film pressure, load carrying capacity, and decreases the response time as compared to classical newtonian-lubricant case. the load carrying capacity decreases as step height increases.
New Method to Generate Reversible Hydrophobic and Hydrophilic Surfaces
V. Mittal and N.B. Matsko
The Open Surface Science Journal , 2009, DOI: 10.2174/1876531900901010007]
Abstract: 7-12 Designer particles synthesized by surfactant-free emulsion polymerization were adsorbed successfully on the sapphire discs. The particles carried a thin layer of an atom transfer radical polymerization (ATRP) initiator on the surface and were subsequently successfully used to graft PNIPAAM brushes from the surface. The surface coverage of the discs by these particles could be improved by heat treatment of the discs which fused the particles with each other but keeping the initial ATRP layer on them. The reversible wetting characteristics of the surfaces as a function of temperature could be established by studying the behavior of water droplets placed on the PNIPAAM modified discs. The heat treated discs improved the reversible behavior further, though no superhydrophobic and superhydrophilic behavior could be achieved. The reversible temperature responsively makes these surfaces tremendously important for the commercial separation and filtration processes.
