    A Study to Assess the Effectiveness of Oral Sucrose on Level of Pain during DPT Immunization among Infants at a Selected Hospital, Salem. Objectives:To assess the level of pain during DPT immunization among infants in experimental and control group. To determine the effectiveness of oral sucrose on level of pain during DPT immunization among infants in experimental and control group. To associate the level of pain during DPT immunization among infants in experimental and control group with their selected demographic variables. Operational Definitions Effectiveness Effectiveness refers to the reduced level of pain among infants in experimental group when compared to control group as measured by modified REILY infant pain Assessment Scale. Oral sucrose Oral sucrose refers to 24% sucrose solution (2ml) given to infants prior to administration of DPT immunization. DPT Immunization It is a vaccine administered intra muscularly in vastus lateralis to prevent DPT. Pain Pain refers to an unpleasant experience observed in the infant during injection as measured by using modified REILY infant pain assessment scale (facial expression, body movement, activity, cry, consolability). Infants Infants refer to the babies of 6 - 14 weeks of age receiving DPT immunization. Hypotheses H1: There will be significant difference in level of pain among infants in experimental and control group after oral sucrose administration during DPT immunization at P < 0.05 level. H2: There will be significant association between the level of pain during DPT immunization among infants in experimental and control group with their selected demographic variables at p<0.05 level. Delimitations: The study was limited to the infants receiving DPT immunization. The study period was limited to only 4 weeks. The sample size was limited to 60 samples. Projected Outcome This study was conducted to determine the effectiveness of oral sucrose on level of pain during DPT immunization among infants. Findings of the study will enable to administer oral sucrose in the way of pain management

    Roman and inverse roman domination in network of triangles

    Get PDF
    In graph G (V, E), a function f : V → {0, 1 2} is said to be a Roman Dominating Function (RDF). If ∀u ∈ V, f(u) = 0 is adjacent to at least one vertex v ∈ V such that f(v) = 2. The weight of f is given by w(f) = P v∈V f(v). The Roman Domination Number (RDN) denoted by γR(G) is the minimum weight among all RDF in G. If V −D contains a RDF f 1 : V → {0, 1, 2}, where D is the set of vertices v, f(v) > 0, then f 1 is called Inverse Roman Dominating Function (IRDF) on a graph G with respect to the RDF f. The Inverse Roman Domination Number (IRDN) denoted by γ 1 R(G) is the minimum weight among all IRDF in G. In this paper we find RDN and IRDN of few triangulations graphs.Publisher's Versio

    Thin bed masonry system: review and future prospects

    Get PDF
    Masonry is one of the most ancient construction materials in the World. When compared to other civil engineering practices, masonry construction is highly labour intensive, which can affect the quality and productivity adversely. With a view to improving quality and in light of the limited skilled labour in the recent times several innovative masonry construction methods such as the dry stack and the thin bed masonry have been developed. This paper focuses on the thin bed masonry system, which is used in many parts of Europe. Thin bed masonry system utilises thin layer of polymer modified mortars connecting the accurately dimensioned and/or interlockable units. This assembly process has the potential for automated panelised construction system in the industry setting or being adopted in the site using less skilled labour, without sacrificing the quality. This is because unlike the conventional masonry construction, the thin bed technology uses thinner mortar (or glue) layer which can be controlled easily through some novel methods described in this paper. Structurally, reduction in the thickness of the mortar joint has beneficial effects; for example it increases the compressive strength of masonry; in addition polymer added glue mortar enhances lateral load capacity relative to conventional masonry. This paper reviews the details of the recent research outcomes on the structural characteristics and construction practices of thin bed masonry. Finally the suitability of thin bed masonry in developing countries where masonry remains as the most common material for residential building construction is discussed

    MOMP from Campylobacter jejuni Is a Trimer of 18-Stranded ÎČ-Barrel Monomers with a CaÂČâș Ion Bound at the Constriction Zone

    The Gram-negative organism Campylobacter jejuni is the major cause of food poisoning. Unlike Escherichia coli, which has two major porins, OmpC and OmpF, C. jejuni has one, termed major outer membrane protein (MOMP) through which nutrients and antibiotics transit. We report the 2.1-Å crystal structure of C. jejuni MOMP expressed in E. coli and a lower resolution but otherwise identical structure purified directly from C. jejuni. The 2.1-Å resolution structure of recombinant MOMP showed that although the protein has timeric arrangement similar to OmpC, it is an 18-stranded, not 16-stranded, ÎČ-barrel. The structure has identified a CaÂČâș bound at the constriction zone, which is functionally significant as suggested by molecular dynamics and single-channel experiments. The water-filled channel of MOMP has a narrow constriction zone, and single-molecule studies show a monomeric conductivity of 0.7 ± 0.2 nS and a trimeric conductance of 2.2 ± 0.2 nS. The ion neutralizes negative charges at the constriction zone, reducing the transverse electric field and reversing ion selectivity. Modeling of the transit of ciprofloxacin, an antibiotic of choice for treating Campylobacter infection, through the pore of MOMP reveals a trajectory that is dependent upon the presence metal ion
