Flea Bite Dermatitis in a Herd of Dairy Calves in Vom Nigeria
SJ Shaibu, IL Oyetunde, LD Jwander, JT Tanko, LT Ikpa, JJ Adamu
Nigerian Veterinary Journal , 2011,
Abstract: Fleas are parasitic insects which are found all over the world. They are wingless insects 1.5-4.0mm long, have a laterally compressed body and are different from lice in they are flattened dorso-ventrally, and are covered with a hard, shiny coating, like an external skeleton, which helps them to move through an animal's fur. There are more than 2,200 species of fleas recognized worldwide (Anon, 2006). Adult fleas are usually red-brown in color and have three pairs of legs, the last pair being quite large and well-adapted for jumping. They have piercing and sucking mouth parts which are specially designed for injecting into a host and sucking blood. They feed on the blood of cats, dogs and other animals, including humans (Lyon, 1997; Kramer and Mencke, 2001). Flea infestation in cattle and other ruminants is rare; it has been more commonly reported in cats and dogs. Infestations of calves with Ctenocephalides felis felis have been reported in Israel (Yeruham et al.,1989), the USA (Dryden et al., 1993) , Japan (Otake et al., 1997) and Brazil (Araujo et al., 1998). Kraal et al. (2006), in a survey of flea infestation, reported the infestation of calves and other domestic animal species in Libya. They reported that of the 1861 fleas recovered, 1857 were Ctenocephalides felis strongylus and 4 were Pulex irritans. Yeruham and Braverman (2004) reported Seasonal allergic dermatitis in sheep associated with Ctenocephalides and Culicoides bites. Ctenocephalides felis felis is a flea of cats and dogs, which is responsible for skin irritation and anaemia (Dryden and Rust, 1994) and transmission of the tape worm Dipylidium caninum (Pugh, 1987). This flea can also infest other mammals including humans (Genchi, 1992).
Approximate indicators for closed subgroups of locally compact groups with applications to weakly amenable groups
Zsolt Tanko
Mathematics , 2015,
Abstract: We generalize the notion of an approximate indicator for a closed subgroup $H$ of a locally compact group $G$ introduced by Aristov, Runde, and Spronk and extend their characterization of the existence of such nets in terms of the approximability of $\chi_{H}$ in an appropriate ${weak}^{*}$ topology. We find that this equivalent condition is satisfied whenever $H$ is weakly amenable and $\chi_{H}$, considered as acting on $\ell^{1}(G)$ by multiplication, extends to a bounded map on $VN(G)$. This occurs in particular when a natural projection $VN(G)arrow I(A(G),H)^{\perp}$ exists. Applications are obtained to the existence (and non-existence) of natural and invariant projections onto $I(A(G),H)^{\perp}$ and $I(A_{cb}(G),H)^{\perp}$ and to the existence of ($\Delta$-weak) bounded approximate identities in ideals of $A(G)$ and $A_{cb}(G)$. In particular, we exhibit a locally compact group without the invariant complementation property.
Rhotrix Linear Transformation  [PDF]

Advances in Linear Algebra & Matrix Theory (ALAMT) , 2012, DOI: 10.4236/alamt.2012.24007
Abstract: This paper considers rank of a rhotrix and characterizes its properties, as an extension of ideas to the rhotrix theory rhomboidal arrays, introduced in 2003 as a new paradigm of matrix theory of rectangular arrays. Furthermore, we present the necessary and sufficient condition under which a linear map can be represented over rhotrix.

INVESTIGATION ON THE EFFECT OF SOME PLANT GROWTH REGULATORS ON SUNFLOWER ( HELIANTHUS ANNUUS L.)
Nurettin Tahsin,Tanko Kolev
Journal of Central European Agriculture , 2006,
Abstract: With a view to establish the effect of some plant growth regulators on sunfl ower (Helianthus annuus L.) production and oil content was made an experiment. The investigation was made on Bulgarian sunfl ower hybrid Super Start, treated during pinhead and fl owering stages. The effect of the tested plant growth regulators on the quantity of yield and some structural elements (sunfl ower heads number, seeds number, seeds mass, mass/ 1000 seeds, oil content % and oil yield kg/da) was reported in the process of investigation. The effect grade of growth regulators is fi xed due to non-treated control. By the dispersal analysis method it is made mathematics processing of the values of received data. The investigation showed that there is not mathematically proved difference between the seed yield kg/da and oil content l/da in pinhead period by the use of plant growth regulators - ‘‘31’’ (1cm3/l water) and ‘’Agat 25 EK’’ (2.5 g/ da). In the fl owering period when treated with the same plant growth regulators seed yield is 15.3 % increased and the oil content -18.6 % (with “31’’) and 16.4 % (with’’Agat 25 EK’’).

Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.32028
Abstract: This study examines the effect of agrochemical used for faming in the Galma Dam area on the quality of water in the reservoir and well water around the reservoir. Nine sampling points upstream of the Galma Dam were randomly se- lected for the study. Also, six hand dug wells in use by adjacent communities were identified for ground water samples. The study covered the period July to September 2011. All measurements were in accordance with the Standard Methods for the Examination of Water and Wastewater. The parameters measured and their mean concentrations from the reser- voir are in the order of: Chlorides (0.600 - 0.900 mg/l); Nitrates (0.009 - 0.019 mg/l); Bicarbonates; 0.444 - 1.900 mg/l); Total Phosphates (0.173 - 3.077 mg/l); Sulphates (0.617 - 3.587 mg/l); and pH (6.4 - 7.5). For the well water samples, the results ranged from 1.58 - 3.10 mg/l; 0.14 - 0.03 mg/l; 0.60 - 2.73 mg/l; 0.08 - 1.89 mg/l; 0.33 - 2.66 mg/l and 6.05 - 7.0 respectively in the order previously listed. The results were statistically analyzed using ANOVA at 95% confidence level. Chlorides showed no significant variation between sampling points but significant variation with dates of sam- pling for surface and well waters. Nitrates variations with both sampling points and dates of sampling were insignificant. Bicarbonates variations with sampling points and dates of sampling were highly significant. Total Phosphates and Sul- phates variations with sampling points and dates of sampling were insignificant and significant respectively. pH values variations with sampling points and dates of sampling were insignificant and highly significant respectively. Generally, the mean concentrations are within the WHO maximum limits of the parameters in drinking water and recommenda- tions were made regarding the use of agrochemicals for farming in the area.

Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.52026
Abstract:

This paper assessed some of the reported cases of building failures and their possible causes in Nigeria between 1977 and 2011. The reported major failure causes are structural failure (SF), Carelessness (CLSS), poor workmanship (PW), poor supervision (PS), poor materials (PM), and quackery (Q).These causes of failure were subjected to Chi-Square statistical test at 5% significant level and 4 degree of freedom to know the most common cause of failure in Nigeria. The analysis showed quackery as the principal culprit in the reported building failures in Nigeria with prevalence of 8 over poor supervision being the minimum in occurrence. Structural failure occurred 5 times, while poor materials, carelessness and poor workmanship occurred 4, 2 and 2 respectively. The Council for the Regulation of Engineering in Nigeria (COREN) with Engineering Regulation and Monitoring (ERM) as her arm as a technical professional group discouraging quackery and failures generally in Engineering Practice. The holistic approach needs effective training of Engineers starting with strong mathematical and scientific background at the secondary and tertiary education levels in conjunction with rigorous field and Industrial training exercises. There after effective scrutiny, professional registration process of competent engineers is followed.

Abstract: Numan is an urban center in Adamawa State North-Eastern Nigeria. Its waste characteristics are similar to other places in sub-Saharan Africa. In this paper, the physico-chemical characterization of municipal solid waste generated in Numan Town was carried out to estimate the electrical power to be generated from it. The solid waste types were observed to comprise of polythene (27%), organic waste (24.1%), plastic (10.2%), textile (13.2%), paper (9.8%), glass (9.3%) and metals (6.4%). The moisture content as discarded and daily average solid waste generation rate are 16.49% and 0.583 kg/sec respectively. The chemical formula with and without water was determined as C923.28H1632.60O258.28N12.89S and C923.28H2099.70O494.16N12.89S respectively. The suitability of the municipal solid waste as a possible source of electrical power was also considered. The energy content of the solid waste on ash free dry-basis was determined as 20861.48 kJ/kg. The estimated power generation per day using incinerating plant at an assumed efficiency of 25% was 3031.5 kW.
Linguistic Choices and Gender Roles in New Nigerian Literature: An Examination of Alpha Emeka’s The Carnival and Razinat Mohammed’s A Love Like a Woman’s and Other Stories
JT Dooga
African Research Review , 2009,
Abstract: This paper is premised on the Systemic Functional approach to text analysis, which considers a work of art as a consequence of the social milieu (Senkoro, 2005). Specifically, it takes Hasan’s (1985) view that without linguistics, the study of literature remains a series of personal preferences. It examines how power is invested along gender lines through language choice in two works of fiction, both by new Nigerian writers: Emeka’s novel The Carnival and Mohammed’s short story collection A Love Like a Woman’s and Other Stories. It seeks to achieve two objectives. The first is to evaluate whether, and to what extent new Nigerian writing is holding onto, or shifting from established ideologies regarding the portrayal of women in fiction, especially by male writers. The second is to compare the two works, The Carnival, by a male writer, with A Love Like a Woman’s written by a female, to see whether and to what extent the two differ in their portrayal of characters of the two sexes. The final part of the paper draws conclusions on the basis of the evidence from the two books that would help in validating the notion of gender positioning in Nigerian fiction, or re-assessing same. The paper argues that such an examination of broader contextual properties oftexts affect their description and interpretation, and concludes that by thus determining positions available within texts, we can make a proper evaluation of how gender is grounded in new Nigerian writing.
Unlearning as a Process of Learning: Practical Aspects in Teaching English in a Second Language Setting
JT Dooga
African Research Review , 2010,
Abstract: This paper addresses pedagogic issues relating to the teaching of English in a second language setting. It argues for a descriptive and functional approach to language teaching and learning and insists that traditional approaches, which tend to be mainly prescriptive, are no longer adequate for addressing the communicative needs of today’s language learners. Specifically, it opines that learning English entails “unlearning” the discomfort we are taught about such things as double negatives. It proposes a dynamic, interactive and collaborative approach to English language teaching and learning. Results of actual classroom experiments are presented to illustrate how instructors can determine the actual language needs of students and thus tailor their instructions to address these. The experiments also support the central argument in this essay that predetermined department-based syllabi might need to be regulated to make them functional to the needs of specific students. As the results of the experiments show, a failure to make such functional alignments could produce students who are only notionally educated but functionally empty.
