Lactational Estrus in Sows, a Way to Increase the Number of Farrowings Per Sow Per Year
M. Alonso-Spilsbury,L. Mayagoitia,M.E. Trujillo,R. Ram?rez- Necoechea,D. Mota-Rojas
Journal of Animal and Veterinary Advances , 2012,
Abstract: During lactation the sow generally remains anestrus. However, lactational estrus and ovulation sometimes occurs under unusual circumstances. Practical outcomes of lactational estrus are reducing the interval between weaning and estrusand therefore the non-productive days in the herd. Although various techniques to induce lactational estrus have been performed through natural management of the animals or the use of exogenous hormones during lactation, induction of estrus during lactation has not been recommended for commercial use. The objective of this study was to review and analyze the basic lactating sow physiology and the different methodologies to induce lactational ovulation, in order to improve her reproductive and productive performance, as a possible alternative to the early weaning system, especially in those cases where lactation length is determined by welfare constraints.
Electrochemical Behaviour Of Carbon Dioxide On Platinum And Rhodium
Anales de la Asociaci?3n Qu?-mica Argentina , 2005,
Abstract: the electroadsorption and electroreduction of carbon dioxide, and the subsequent electrooxidation of reduced carbon dioxide was studied on polycrystalline and electrofaceted pt and on polycrystalline rh electrodes. the influence of the adsorption potential and the adsorption time was established. combining voltammetric charge measurements and differential electrochemical mass spectrometry (dems) analysis, three adsorbates were tentatively identified, namely cooh and co in bridge and linear configurations on pt, and coh in triple and single adsorption configurations on rh. by applying medium frequency potential routines on the pt-adsorbate/sulphuric acid interface, the existence of equilibrium between adsorbates was demonstrated.
The effect of Diazepam in pain reduction following mandibular impacted third molar surgery
Daneshvar M.E
Journal of Dental Medicine , 2004,
Abstract: Pain control is of high importance in dentistry. Prescribing sedatives such a"nDiazepam, as an anti-depressant and pain threshold elevator drug is able to influence the patient's reaction to"npain and reduce it."nPurpose: The aim of the current study was to evaluate the effect of Diazepam in pain reduction following"nmandibular impacted third molar surgery."nMaterials and Methods: In this study, which was conducted in the department of Oral and Maxillofacial"nsurgery Faculty of Dentistry, Tehran University of Medical sciences. The patients were divided into two equal"ngroups (n=30). For controls, antibiotics and analgesics were prescribed after surgery. However, except the"naforementioned drugs, Diazepam (5mg), three times per day, was prescribed for the experimental group. The"namount of mouth opening was also measured as an auxiliary sign after one week. The data were compared by"nX2 test after one week."nResults: 60% of the experimental group and 13.8% of the control group felt a weak pain. Statistically"nsignificant differences were observed regarding pain feeling between two groups (P<0.001). Severe pain"nfeeling was 34.5% and 10%, for control and experimental groups, respectively."nConclusion: It is suggested that Diazepam is an effective pain reduction drug following third molar surgery."nThis drug has also a relative effect on temporary trismus resulting probably from muscle trauma or pain.
Metaphors, domains and embodiment
M.E. Botha
Koers : Bulletin for Christian Scholarship , 2005, DOI: 10.4102/koers.v70i3.277
Abstract: Investigations of metaphorical meaning constitution and meaning (in-) variance have revealed the significance of semantic and semiotic domains and the contexts within which they function as basis for the grounding of metaphorical meaning. In this article some of the current views concerning the grounding of metaphorical meaning in experience and embodiment are explored. My provisional agreement with Lakoff, Johnson and others about the “conceptual” nature of metaphor rests on an important caveat, viz. that this bodily based conceptual structure which lies at the basis of linguistic articulations of metaphor, is grounded in a deeper ontic structure of the world and of human experience. It is the “metaphorical” (actually “analogical”) ontological structure of this grounding that is of interest for the line of argumentation followed in this article. Because Johnson, Lakoff and other’s proposal to ground metaphorical meaning in embodiment and neural processes is open to being construed as subjectivist and materialist, I shall attempt to articulate the contours of an alternative theory of conceptual metaphor, meaning and embodiment which counteracts these possibilities. This theory grounds metaphorical meaning and meaning change in an ontological and anthropological framework which recognises the presence and conditioning functioning of radially ordered structures for reality. These categorisations in which humankind, human knowledge and reality participate, condition and constrain (ground) analogical and metaphorical meaning transfer, cross-domain mappings, and blends in cognition and in language, provide the basis for the analogical concepts found in these disciplines.
Clusters, roots and hierarchies of metaphors in Scripture and the quest for Christian scholarship
M.E. Botha
Koers : Bulletin for Christian Scholarship , 2004, DOI: 10.4102/koers.v69i3.315
Abstract: This article explores how the confessional thrust of Scriptural and root metaphors relates to the Christian scholar’s quest and how choices for hermeneutical keys to Scripture relate to metaphorical keys chosen as means of access to reality. With respect to Biblical interpretation it is argued that the text of Scripture itself provides the theologian or reader with leads concerning the kind of metaphorical access that functions as its hermeneutical key. I argue that there are clusters or hierarchies of metaphors, central and root metaphors, that regulate the interpretation of Scriptural texts and that a redemptive historical reading of Scripture as a confessional text guides the meaning of such clusters and hierarchies of metaphors. I argue that root metaphors in Scripture set the certitudinal parameters for the metaphors chosen and utilised in the disciplines. Regarding reality I argue that the recognition of the multidimensionality of reality and the plurivocity of meaning and signification on which we rely in both literal and metaphorical language use and reference assumes the existence of non-linguistic and preconceptual bases that guide the recognition of similarities, differences and analogies in reality. They in turn are pointers to a design plan for reality which one could call a God-given order of creation. Metaphorical meaning appeals to and presupposes such an ordered and categorised world to which language and texts refer and which provides limits and boundaries to the multiplicity of deferrals of meaning that intertextual relationships seem to imply. In disciplines concerned metaphorical models play a hermeneutical role in the understanding and interpretation of reality. In these metaphorical models, control beliefs steer, guide and condition the access of the discipline to reality. For Christian scholars the ultimate presuppositions embedded in control beliefs need to comport with the thrust of Scripture and its root metaphors. Scholars are at work in God’s creation and their metaphorical approximations of the structures of this creation are guided by the contours of created reality. These approximations in turn are influenced and constrained by what they attribute ultimacy to in the process of attempting to understand this reality. Stable God-given order provides the conditions and parameters for the common differentiation of contexts within which the interpretation of God’s Word in creation is to take place.
Discipling scholars and teaching teachers – towards a Biblically-based understanding of faculty development
M.E. Botha
Koers : Bulletin for Christian Scholarship , 2004, DOI: 10.4102/koers.v69i4.321
Abstract: Faculty development is often a life-long process which does not bear fruit in one tenure-track term. Christian colleges and universities need to recognise that more factors contribute to faculty development than only those added to faculty development programmes on university campuses. Challenging university lecturers and academic teachers to change, even to cumulative change over the span of a lifetime, is what faculty development is all about. In order to achieve this goal we need, however, to develop an atmosphere and an ethos on campus that is conducive to such growth and change. Such an ethos should be rooted in an integral Biblical view of the world, but primarily in a world view that sees both professors, lecturers and students as gifted and unique beings called to be followers of Christ – also in an academic environment
Acta Medica Iranica , 1983,
Abstract: The present work with consideratlon to the autoradiographic pictures, suggests that cholinergic receptors are located at the gate of a channel originating from synaptic cleft coming to lie within the muscle fibre. AChE molecules stand at the gate of this channel,controlling the entrance of different cholinergic agents. It was report- ed previously that dtc molecules s t.abD ;:.2e the AChE rnolecules and will obstruct the gate. This blocks the acess of ionic flux within the channel thus producing a non-depolarizing neuromuscular paralysis.The presented experiments imply that depolarizing agent will bring a considerable change in conformation of AChE mole cule and this causes the opening of the gate allowing ioni flux and depolarization .In case of ACh this process is repeated in a fraction of milli second, due to rapid regeneration of AChE while in case of suxamethonium and neostigmine(given in high dose), the regeneration of AChE takes much longer time thus will produce a depolarizing blockade. In this hypothepis the main responsa~ility of AChE"nis confined to identification of cholinergic agents and Cooperation in their function so,it can be accepted as Cholinergic receptor. In regard to clinic, this work suggests that only the use of minimum effective dose of neostigmine is advisable, in reversing curarisation. In contrast to general belief , the dose of neostigmine should be s elec t ed in relation to r eceptor dtc occupation and not depending on pati ent 's weight . As it was demonstrated , the early use"nof high dose o f neostigmine may a lso potent i a te curar i s a tion
Of light and limits: Philosophy matters
M.E. Botha
In die Skriflig , 2002, DOI: 10.4102/ids.v36i2.505
Abstract: The deepest religious or faith commitments of a scholar enter into her theoretical work through the mediation of a (scientific) world view with its embedded philosophical assumptions about the subject matter. These philosophical assumptions are about the fundamental structure (order) of the world and imply assumptions about the nature of this order or structure. They are often embedded in theoretical notions that purport not to require any further grounding. As such they are thoroughly “religious”. Metaphorical language and models often mediate these religious convictions. Christian scholarship implies critically weighing and assessing such assumptions and exposing their ideological or mythical nature. The pivotal issue at the centre of the historical “turns” in philosophy of science appears to be diverse articulations of this locus of order. It is this perennial search for the elusive universal that surfaces in each of the “turns” in either philosophy or science which “turns” up with monotonous regularity in subject-related literature. All these “turns” seem to be bound in their point of departure to an epistemological position which could best still be described as that of modernity, i.e., anchored in the Enlightenment ideal of the subject-object divide and the belief that objective rational knowledge can be acquired, yet attempting to approach this rational objective knowledge via the medium of the knowing subject. This perennial search for the elusive universal reaches a dead-end in post-modernism. If Christian philosophy wants to shed light on this issue so central to the heart of theorizing, it needs to develop a dynamic understanding of the notion of law, order, limits and boundaries and the way such an understanding could inform the discussions concerning scientific realism and the end(s) of philosophy.
Pastoral care and the agony of female singleness in the African christian context
M.E. Baloyi
In die Skriflig , 2010, DOI: 10.4102/ids.v44i3&4.169
Abstract: In our society the norm is thatevery adult should get married one day. This could imply thatunmarried people do not feel welcome either in the community or the church. They may feel neglected or even like outcasts. It is a pity that the church, which also finds itself within the community, is composed of people who still continue to havethe kind of attitude that excludes singles, even inside church circles. While churches run programmes that have a strong emphasis on marriage and family life, nothing is being doneto address singleness and its related problems. As a result, singles often regard themselves as unimportant and worthless. This article is aimed at un-covering the role of the church through its leadership (pastors in particular) to assist and helpto redeem the damaged image and self-esteem that singles may have in their respective communities and churches. The article focuses on singles in the African church and society. It is crucial that a church programme of care and counselling be structured in order to minister to persons who are separated, divorced, widowed or never married for whatever reason.
