The effects of mixing slurry water with type III gypsum on setting time, compressive strength and dimensional stability

Background: Type III gypsum is a material used to make dental master casts. It may be added to an accelerator, such as slurry water, to shorten setting time. Calcium sulphate in slurry water may affect setting time, compressive strength and dimensional stability. Purpose: The study evaluated the effect of slurry water on the setting time, compressive strength and dimensional stability of type III gypsum. Methods: Eighty-one samples were made of type III gypsum, divided into three groups: group A was gypsum mixed with 1% slurry water, group B, gypsum mixed with 2% slurry water and group C, gypsum mixed with distilled water. Each sample was formed using a standardised master mould. For testing setting time, a cylindrical mould 25 mm in diameter and height was used; for compressive strength testing, the cylindrical mould was 20 mm in diameter and 40 mm in height; and for dimensional stability testing, a pair of cylindrical, ruled block and mould were used. Setting time was tested using Vicat’s apparatus; compressive strength was tested using a universal testing machine; and dimensional stability was tested using digital callipers. The data were analysed by one-way analysis of variance (ANOVA) and least significant difference (LSD) tests. Results: One-way ANOVA and LSD tests showed significant differences in the effect of slurry water on the setting time, compressive strength and dimensional stability of type III gypsum (p<0.05). Conclusion: The use of slurry water can shorten setting time, decrease compressive strength and increase dimensional change of type III gypsum.

THE MAIN DIRECTIONS OF THE EVOLUTION OF EAST EUROPEAN SPIRIFERIDS FOR CARBONIFEROUS AND MODERNIZATION OF FAMILY GROUP SYSTEM

The short review of the history of the Order Spiriferida system have been done. The leading directions of evolutions of the majorgroups of Carboniferous spiriferids of Eastern Europe were determined. The main changes in the content of SuperfamiliesMartinioidea and Spiriferoidea were substantiated by the author. The family Brachythyrididae containing the subfamiliesBrachythyridinae and Skelidorygminae was included in Superfamily Martinioidea. The Family Angiospiriferidae according to author’sopinion contains the Subfamilies Angiospiriferinae Legrand-Blain, Brachythyrininae Waterhouse, Choristitinae Waterhouse, andwere included in Superfamily Spiriferoidea. The new Superfamily Neospiriferoidea containing the families Imbrexiidae Carter,Neospiriferidae Waterhouse, Trigonotretidae Schuchert, Spiriferellidae Waterhouse was established. The evolution of morphologyspiriferids and manner to fix the shells to ground were associated with change of type of sediments in Carboniferous.

Risk Assessment of Unusual Transactions in Internal Control Procedures

Th e article deals with the problems associated with assessing the risks of unusual operations in the internal control procedures of an economic entity. Th e author analyzes such concepts as «termination of activity», «change of type of activity» and «bankruptcy» as unusual operations, which, when certain conditions occur, can have a negative impact on the achievement of the goals of an economic entity.

<p>Copyright is a high reality of various values, including economic value, this is because copyright that is born of copyright, taste, and intention is able to color the development of human life through objects born from the copyright process.

Change in biomarkers of type-2 inflammation following severe exacerbations of asthma

We investigated the time course of change of type-2 asthma biomarkers after a severe asthma exacerbation. Blood eosinophils were lowest immediately after treatment was initiated (0.07 vs 0.33×109/L, p<0.001) while serum IgE levels were at their highest (339 vs 249 U/L, p<0.001). Fractional exhaled Nitric Oxide levels were lowest 2 weeks after treatment (23 vs 33 ppb, p=0.06) and serum periostin levels were lowest 1 week after treatment (45·9 vs 50·9 ng/mL, p<0.001). A delay of 4–8 weeks following a severe exacerbation is required if these biomarkers are used to guide the ongoing management of patients with asthma.Trial registration numberPost-results; The Australia New Zealand Trial Registry, >ACTRN12614000443695.

Nisan Plakpling, Tipe Nisan Peralihan dari Pra- Islam ke Islam

The plakpling gravestone type spreaded a lot in Aceh, which is quiet possible that it’s a change of type from pre Islam to Islam era. From the inscriptions on it’s surface, this gravestone was assumed that it’s older than other gravestones.
