Logistics Regression of Parents’ Raising Style on Marital Harmony

This study analysed demographically the logistic regression of parents’ raising style on marital harmony among members of Yabatech community of Yaba, Lagos State, Nigeria. The objectives of this study were to determine whether parents’ child raising style influence marital harmony among married couples and to determine whether socio demographic factor like age, educational status, gender and marital status influence marital harmony among married couples. A cross-sectional survey of 206 Yabatech community members aged 20-40 years who are married and have at least a child purposively selected was doneusing an adapted questionnaire. The data was analysed using Chi-square test andLogistics Regression. The result revealed that all the sociodemographic factors were significantly associated with marital harmony (p <0.05). The Logistics Model fitted is ln(Marital Harmony) = 1.258 + 1.331 APS1 -1.667 APS2 + 1.319 PPS. It was therefore concluded that while the three parental styles have significant impact on marital harmony (p < 0.05), authoritative parental style (APS1) and permissive parental style(PPS) have positive impact and authoritarian parental style(APS2) has negative impact. It was recommended that parents should adopt authoritative and permissive parental style of raising children since it has a better chance of giving marital harmony.
Application of mtDNA Sequencing Method for Individual Identification in Rustling

Abstract Liu, Y. , Zhao, X. Zhang, N. , Luo, X. and Tong, Z. 2007. Application of mtDNA sequencing method for individual identification in rustling. J. Appl. Anim. Res., 32: 77–80. The mitochondrial DNA (mtDNA) sequencing has extensive use in human forensics particularly for identification of individuals. In this case report a cattle was being claimed by two owners. Using this technique the disputed cattle was compared with purported mothers, brother, sister and son and the real relatives were identified. However, it has the limitation of being used only in case of different maternal lineages.
Identification of Soil Enriched Microorganisms using 16S rDNA analysis for Crop Prodctivity

In the present study, occurrence of cultivable bacteria in the soils of Chandan plant (Santalum album) and Bamboo plant (Bambussa bambus) was investigated. Soils are likely to include species of various bacterial phyla, so different colony characteristics isolates were selected and 16S rDNA sequences were amplified from the samples. Five genera (MS2) and 3 genera (MS1) were identified by 16S ribosomal RNA gene sequence analysis (similarities to known 16S rDNA sequences). The majority of bacteria were Bacillus belonged to Firmicutes in MS2. While the presence of Pseudomonas, Micrococcus and Enterobacter were less. The endophytic bacterial community was also present in MS1 sample. In addition, phylogenetic analyses were also used to infer the makeup of bacterial communities in the soil samples. As a result, our isolates (from both soil) nicely clustered with reference sequences (16S rDNA sequences). Our results show that the population diversity of cultivable bacteria is abundant in the both soil types. These cultivable bacterial consortium may be used in crop production.
COMPARATIVE STUDY BETWEEN PSPWM AND SVPWM TECHNIQUES BASED ON MLI FOR INDUCTION MOTOR DRIVE

Multi-level inverters (MLIs) are recently the promising converters for high-power medium-voltage AC drives due to their superior characteristics over conventional 2-level converters. This paper presents a study for the performance of Induction Motor drive using different modulation techniques based on Multi-level cascaded inverter topology. The applied pulse width modulation (PWM) techniques are Phase shifted PWM which is the preferred Sinusoidal PWM for this topology and space vector PWM. A simple space vector modulation algorithm is introduced for this comparison. A passive filter is carefully designed in order to reduce the distortions of the resulted voltage and current waveforms to safe limits. Experimental setup is implemented for this study using DS1104 control unit. In this paper, simulation and experimental results are carried out to investigate the differences between the modulation techniques for these drives.
Detection of sub-tidal mussel beds on rocky reefs using acoustics

The collection of recently settled wild mussels from beach-cast seaweed provides the seed for a large and rapidly expanding mussel aquaculture industry in New Zealand, but the locations of adult populations producing this seed are unknown. Traditional methods of assessing sub-tidal habitats of rocky reefs (diver census, video camera drops) are neither cost-effective nor practical for the relatively large spatial scales involved. Remote sensing tools offer solutions to this problem. We tested the ability of the acoustic seafloor classification system, Quester Tangent Corporation (QTC) Impact, to detect the presence of green-lipped mussel (Perna canaliculus) populations on sub-tidal rocky reefs. Acoustic data were collected from a range of visual subtidal habitats, combined, and analysed using QTC Impact's principal component analysis and clustering software. Discriminant function analysis assessed whether visually distinctive habitats could be correctly classified using this acoustic data only. Consistent and reliable classifications were found for continuous mussel beds (100% correct, 0% misclassification from other habitat types), and sand, while the other various classes of rocky reef habitats (i.e. reef with varying levels of biological cover of kelps and encrusting invertebrates, including occasional mussel patches at one site) were identifiable to a general class of rocky reef, without significant mussel cover. These results demonstrate that QTC Impact can reliably discriminate subtidal mussel beds on rocky reefs from other habitats, making it feasible to proceed with large-scale mapping.
High speed imaging and analysis of turbulent flames

The study of time-dependent phenomena in turbulent flames requires detailed knowledge of both the chemistry and flowfield interactions that are present in regions of localized extinction or ignition. Recent developments in burst-mode laser technology, coupled with high-speed CMOS detectors, allow imaging at rates sufficient to resolve small-scale variations in highly turbulent flows. The pulse-burst laser systems employed in the current work are capable of achieving pulse burst lengths in excess of 30 ms (with all-diode pumping), and in excess of 10 ms (with flashlamp pumping). Pulse-burst laser systems consist of a pulse sliced continuous-wave or pulsed oscillator which is subsequently amplified through an Nd:YAG amplifier chain. This design allows great flexibility in the pulse repetition rate, burst duration (or total number of pulses), and the energy per pulse. The long pulse duration and high repetition rate ensures that a large range of important temporal frequencies ranging from 100 Hz to 50 kHz can be captured in a single burst. The system design targets >200 mJ/pulse at 20 kHz, with >35 mJ/pulse at 355 nm. The efficient frequency conversion of these laser systems allows investigation of UVaccessible transitions of OH, CH2O, CH, NO, and acetone for planar laser-induced fluorescence (PLIF), as well as scattering experiments in the visible range. This paper discusses the current capabilities for planar imaging of combustion species and mixture fraction. The data are also evaluated to determine the requirements for sufficiently resolving spatio-temporal dynamics in turbulent flows. In particular, the application of wavelet analysis to nonlinear time series generated from the two-dimensional data is investigated. The wavelet transfom is complimented through an investigation of the energetic modes for example, in mixing, by proper orthogonal decomposition of the image series. In these analyses, it is of interest to determine the experimental requirements to accurately capture local turbulent combustion phenomena.
Intelligent virtualization of crane lifting using laser scanning technology

Background This paper presents an intelligent path planner for lifting tasks by tower cranes in highly complex environments, such as old industrial plants that were built many decades ago and sites used as tentative storage spaces. Generally, these environments do not have workable digital models and 3D representations are impractical. Methods The current investigation introduces the use of cutting-edge laser scanning technology to convert real environments into virtualized versions of the construction sites or plants in the form of point clouds. The challenge is in dealing with the large point cloud datasets from the multiple scans needed to produce a complete virtualized model. The tower crane is also virtualized for the purpose of path planning. A parallelized genetic algorithm is employed to achieve intelligent path planning for the lifting task performed by tower cranes in complicated environments taking advantage of graphics processing unit technology, which has high computing performance yet low cost. Results Optimal lifting paths are generated in several seconds.
Frequency of Injuries in Three Raptor Species Wintering in Northeastern Arkansas

Abstract It may be reasonable to assume that raptors would likely perish as the result of an injury that potentially impaired their ability to capture prey. We present results from 98 wild-caught raptors that support the converse claim: raptors can and do survive with many types of injuries. We report a conservative injury estimate of 14% for wintering populations of Red-tailed Hawks (Buteo jamaicensis), American Kestrels (Falco sparverius), and Cooper's Hawks (Accipiter cooperii) in northeastern Arkansas. Injuries in these species included broken or missing talons, ulcerative pododermatitis (bumblefoot), missing toes, healed wing fractures, and iris damage.
Studies on ozone initiated inactivation of pathogenic bacteria in aqueous systems

The effect of ozone on the inactivation of two Gram -negative strains ( Escherichia coli and Pseudomonas aeruginosa) and one Gram-positive endospore ( Bacillus subtilis) bacteria, often present in water and the cause of s ome waterborne diseases was investigated as a function of ozone concentration a nd ozonation duration. Ozone was generated in situ using corona discharge methods where the ozone con centration ranged from 0.906 4.724 mg/L and the inactivation of the ree microbes followed pseudo-first order kinetics with respect to the microbes. Three microbes were cultured and the influence of temperature and pH of the aqueous syst ems on the ozone initiated inactivation rate of the three microbes was also in vestigated. This study reports that molecular ozone is more effective than hydroxyl rad ic ls initiated by the ozone chain reactions. Two suggested mechanisms for the antimi crobial effectiveness of ozone in water systems from the literature is discussed. The study also found that ozonation significantly decreased the Biological Oxygen Deman d (BOD) value of natural water.
Design and Analysis of Optimal Threshold Offloading (OTO) Algorithm for LTE Femtocell/Macrocell Networks

LTE femtocells have been widely deployed to increase network capacity and to offload mobile data traffic from macrocells. While cellular users' mobility behaviors are taken into consideration, a dilemma is formed: Should a User Equipment (UE) either handover into a femtocell or keep the current connection with a macrocell? Indeed, various user mobility behaviors may incur significant signaling overhead and degrade femtocell offloading capability due to frequent handover in/out femtocells. To address this dilemma, in this paper we propose an Optimal Threshold Offloading (OTO) algorithm considering the tradeoff between the signaling overhead and femtocell offloading capability. We develop an analytical model and define two performance metrics to quantify the tradeoff. The proposed model not only models user mobility behaviors but also captures femtocell offloading benefits, and shed light on their fundamental relationship. The correctness of analytical model and simulation model are cross-validated by extensive ns2 simulations. Both analytical and simulation results demonstrate that the OTO algorithm can significantly reduce signaling overhead at the minor cost of femtocell offloading capability. The results enable wide applicability in various scenarios, and therefore, have important theoretical significance. Moreover, the analytical results provide a quick way to evaluate signaling overhead and offloading capability in LTE networks without wide deployment, saving on cost and time.
BIOLOGICAL CONTROL OF THE RED PALM WEEVIL

This work has been carried out in Saudi Arabia through the project of “Transfer of bio-control techniques to management of the red palm weevil in Middle East” a project conducted by “Arab Organization for Agricultural Development” (AOAD). The overall objective of this work was to contribute to the decision makers a program for the biological control of the red palm weevil (RPW) with entomopathogenic nematodes (EPN). This biological control program is ready to be transferred into IPM program of the pest in our Arabic region. The specific objectives were (1) isolation and identification local entomopathogenic nematodes from Saudi Arabia and Qatar, (2) Laboratory evaluation of the nematodes against adults of the RPW, (3) studying the suitability of new nematodes to mass production, (4) semi field evaluation of the nematodes against adults of RPW in date palm trees, and (5) field application of local nematodes against natural population of RPW in date palm farms. Tow isolates of EPN of genus Steinernema had been discovered. It was the first record of Steinernema from Saudi Arabia and Qatar. Laboratory studies showed that the two new isolates were highly virulent to the RPW. They had high reproductive potential producing 400000600000 nematodes/Galleria mellonella larva. The studies showed differences between the two isolates in their values of lethal concentration MME Saleh Pests and Plant Protection Department, National Research Centre, Elbehooth Street, Dokki, Cairo, Egypt.

Persistence of Maternally-Derived Antibody in Selected Group of Chicks to Fowl Pox Virus

The investigation was conducted to determine the persistence of maternally derived antibody as well as its influence on vaccination programme against fowl pox infection. A total of 60-day-old chicks divided into four groups such as A, B, C, D. Chicks of Group A and B were used for the detection of persistence of maternally derived antibody which are originated from fowl pox virus-vaccinated and non-vaccinated parent stock respectively. For the detection of antibody level after vaccination with live fowl pox and pigeon pox virus vaccine following two vaccination schedules, chicks of group C and D were subdivided into group C 1 , C 2 and D 1 , D 2 originating from fowl pox virus vaccinated and non-vaccinated parent stock. It is found that maternally derived antibody passed over from the parents to progeny chicks and remains protective level for the chick of group A until day 4 of age and the chicks of group B which are originated from non-vaccinated parent stock remains protective level only at day 1. Chicks of subgroup C 2 and D 2 produce higher antibody titre, which were boosted at 15 days interval. Frequent out breaks of fowl pox infection in chicks of Bangladesh either from fowl pox virus-vaccinated and non-vaccinated origin may be avoided by vaccination with pigeon pox virus vaccine at day 5 followed by a secondary vaccination with fowl pox virus vaccine at day 21.

Identification of intrinsic dimer and overexpressed monomeric forms of γ-tubulin in Sf9 cells infected with baculovirus containing the Chlamydomonas

γ-tubulin polypeptide from the complex in the presence of MgATP. The released γ-tubulin monomers were capable of binding to microtubules in vitro and biochemical quantities of active monomers were further purified using a combination of size-exclusion and ion-exchange column chromatography. The endogenous Sf9 cell γ-tubulin migrated faster than Chlamydomonasγ-tubulin with an apparent molecular mass of 49 kDa on gels. Analyses on gel filtration and sucrose density gradient centrifugation showed that, while overexpressed Chlamydomonasγ-tubulin was present in a monomeric form, endogenous γ-tubulin from Sf9 and HeLa cells exists as a dimer. These results may suggest the possibility that γ-tubulin could form a heterodimer with hitherto unknown molecule(s). SUMMARY
Minimizing Stem Elongation During Spray Applications of Gibberellin4+7 and Benzyladenine to Prevent Leaf Chlorosis in Easter Lilies

Several experiments were conducted to find effective ways of utilizing gibberellin 4+7 (GA 4+7 ) and benzyladenine (BA) to prevent leaf chlorosis during greenhouse production of Easter lilies (Lilium longiflorum Thunb.) while minimizing the undesirable side effects on stem elongation. On an absolute concentration basis, GA 4+7 was much more effective than BA in preventing leaf chlorosis. Excessive levels of GA 4+7 , however, tended to cause stem elongation. When applied at around the visible bud stage, if the foliage was well covered with the spray solution, 25 mg.L -1 of GA 4+7 was adequate for maximum protection against leaf chlorosis. Increasing the GA 4+7 concentration above 25 mg.L -1 gave no additional benefit on leaf chlorosis. Two possible modes of GA 4+7 uptake during a foliar spray application (absorption through leaves and stems, and root uptake of the extra run-off) were studied in terms of their relative contribution to leaf chlorosis and stem elongation. Although both modes of uptake prevented leaf chlorosis, foliar uptake was much more effective than root uptake. However, GA 4+7 taken up by the roots contributed mainly to stem elongation. When sprayed to leaves on only the lower half of the plant, a 10-mL spray of either 25 or 50 mg.L -1 of each GA 4+7 and BA was enough for complete protection against leaf chlorosis. Increasing volumes had no additional benefit on leaf chlorosis, but increased the chances of unwanted stem elongation.
Cloning and characterisation of a novel cry1H gene effective against lepidopterous larvae from a Bacillus thuringiensis strain

We characterised a novel holotype cry gene (cry1Hc1) harboured in BN23-5 Bt strain which was isolated from soil samples in Sichuan, China. In this study, the full length of the cry1Hc1 gene was cloned from the strain. The cry1Hc1 gene was inserted into a shuttle vector (pSTK) and expressed in an acrystalliferous mutant Bacillus thuringiensis HD73−. In this transformant, cry1Hc1 was expressed and diamond-shaped parasporal crystals were formed. The resulting insecticidal activity showed that the Cry1Hc1 protein exhibited high larvicidal activity against larvae of Plutella xyllostella and Ostrinia furnacalis with lethal concentration 50 of 55.21 and 118.44 μg/ml, respectively. Sequence analysis of the gene was also performed; the Cry1Hc1 protein retained eight conserved regions commonly found in the existing Cry proteins.
A Natural Hybrid Between Ligularia paradoxa and L. duciformis (Asteraceae, Senecioneae) From Yunnan, China1

Abstract A putative natural hybrid in Ligularia Cass. , which is morphologically intermediate between L. paradoxa Hand. -Mazz. and L. duciformis (C. Winkl.) Hand. -Mazz. , was found on Mt. Maoniu in northwestern Yunnan, China. We employed analyses of morphology, seed vigor, somatic chromosome numbers, meiotic behavior of chromosomes, inter-simple sequence repeat (ISSR) markers, and trnL-F sequencing to test the hypothesis that the unidentified taxon is a natural interspecific hybrid between L. paradoxa and L. duciformis. Examination of morphological characters demonstrated the intermediacy of the putative natural hybrid between L. paradoxa and L. duciformis. Seed germination of the putative natural hybrid was absent, and no embryo was found in seeds of the putative natural hybrid. The meiotic behavior of the putative natural hybrid was abnormal. Among 10 ISSR primers that we tested in all three taxa, four primers produced different ISSR markers between the putative parents. The putative natural hybrid shared all ISSR markers of the putative parents. However, no taxon-specific band existed in the samples of the putative natural hybrid. The data from ISSR markers are concordant with morphology in implicating L. paradoxa and L. duciformis as parents of the putative natural hybrid. Ligularia paradoxa was determined as the female parent of this natural hybrid by nucleotide sequence from the chloroplast trnL-F region. Therefore, this taxon is confirmed to be a natural hybrid between L. paradoxa and L. duciformis and is described herein.
Oxidative and genotoxic effects of Thymoquinone, Nigella sativa active compound, in Balb/c mice

Nigella sativa has been traditionally used for the treatment of many ailments. Experimentally, it has been demonstrated that N. sativa extracts and Thymoquinone (TQ), the main compound of their volatile oil, possess several biological activities such as antioxidant, anti-inflammatory and hepato-protective properties. To further evaluate the oxidative damage and genotoxicological properties of TQ in vivo, this compound was injected with increasing doses by intraperitoneal route to Balb/c mice, and both oxidative and genotoxic effects were tested. Malondialdehyde (MDA) levels and catalase (CAT) activity in liver and kidney were determined as endpoints of oxidative damage, while chromosomal aberrations and the DNA damage index in liver and kidney served as endpoints of genotoxicity. These experiments showed that TQ demonstrated oxidative and genotoxic effects in a concentration dependent manner by inducing significant increase of MDA level and CAT activity from 40 mg/kg body weight (b.w). At high dose (80 mg/kg b.w.), TQ significantly increased chromosomal aberrations and the DNA damage index in liver and kidney. These results contradict the reports indicating antioxidant and anti-genotoxic effects. Key words: Nigella sativa, Thymoquinone, Malondialdehyde (MDA), catalase, comet test, chromosomic abberations.
