Experimental Study on the Mechanical Properties of Concrete using Iron Waste as Partial Replacement of Fine Aggregate

Plenty of Iron waste is available from steel plant, Sohar and it will affect the environment when it is dumped in soil. Also, every year huge quantity of concrete is used for building construction in Oman. In this project work, iron waste was collected from Sohar steel plant and was mixed with concrete. The aim of this study is to determine the mechanical properties of concrete with iron waste to be compared with normal concrete. The percentages of iron waste can be added to concrete as 0%, 10%, 15% and 20% were based on literature review. For experimental work, cubes were casted with iron waste. Also, slump test was conducted to measure the workability of fresh concrete. Furthermore, density of concrete with and without iron waste was determined. Finally, compressive strength test of concrete cubes was done for C30 grade concrete. Test result shows that compressive strength is reducing by increasing iron waste percentage

A Viewpoint on Accent Services: Framing and Terminology Matter

Purpose: The purpose of this article is to offer a contemporary viewpoint on accent services and contend that an equity-minded reframing of accent services in speech-language pathology is long overdue. Such reframing should address directly the use of nonpejorative terminology and the need for nurturing global linguistic diversity and practitioner diversity in speech-language pathology. The authors offer their perspective on affirmative and least-biased accent services, an in-depth scoping review of the literature on accent modification, and discuss using terms that communicate unconditional respect for speaker identity and an understanding of the impact of accent services on accented speakers. Conclusions: Given ongoing discussions about the urgent need to diversify the profession of speech-language pathology, critical attention is needed toward existing biases toward accented speakers and how such biases manifest in the way that accent services are provided as well as in how clinicians conceptualize their role in working with accented speakers. The authors conclude with discussing alternate terms and offer recommendations for accent services provided by speech-language pathologists

A Feasibility Study on Using Gfrp Composites Bar in Rc Flexural Member

Steel reinforcements are commonly used for Reinforced Concrete (RC) beams all around the world to take flexural tension. But, the durability of the structure is reduced due to reinforcement steel corrosion. Avoiding reinforcement corrosion and finding alternative material to take flexural tension is the contemporary research work in the field of structural engineering. In the present study, RC beams are reinforced with Glass Fibre Reinforced polymer (GFRP) composites bar at tension zone and flexural test was carried out to determine the bending moment resistance of the beam. GFRP bars were prepared in the industry with the help of pultruded U-section box formwork. GFRP bars were coated with sand using epoxy resin to increase the bond between bars and the RC beam. Three GFRP reinforced concrete beam specimens of size 700 mm × 200 mm × 200 mm were prepared. Also, same size of normal steel reinforced cement concrete beam member was prepared. After 28 days curing, three point bending test was carried out for all the four beams. Flexural capacity of beams with GFRP bars were compared with RC beam with steel bars. The results revealed that the flexural capacity of RC beams with GFRP bars is more than that of RC beam with steel bars. Also, theoretical analysis was carried out to determine the flexural strength of RC beam with steel and GFRP bars and compared with experimental results

Consonantal and vocalic gestures in the articulation of italian glide /w/ at different syllable positions

Glides have been a challenging sound category from both a phonological and phonetic perspective and this is especially true for Italian. In this language four different glides can be distinguished based on their position in a syllable (pre or post-vowel), grouped together as either "semi-consonanti" (/j/ and /w/) or "semi-vocali" (/i̯/ and /u̯/). As most studies on Italian glides have utilized acoustic data, there is little information on actual articulatory characteristics. In this paper, we present a detailed kinematic analysis of both consonantal and vocalic gestures involved in the production of one specific glide (/w/) using 3D electro-magnetic articulography (EMA). The findings allow us to distinguish between different theoretical frameworks on the nature of glides and interpret possible changes in their pro-duction in relation to variations in speech rate and position in the syllable

Treatment intensity and childhood apraxia of speech

BackgroundIntensive treatment has been repeatedly recommended for the treatment of speech deficits in childhood apraxia of speech (CAS). However, differences in treatment outcomes as a function of treatment intensity have not been systematically studied in this population.AimTo investigate the effects of treatment intensity on outcome measures related to articulation, functional communication and speech intelligibility for children with CAS undergoing individual motor speech intervention.Methods &amp; ProceduresA total of 37 children (32-54 months of age) with CAS received 1x/week (lower intensity) or 2x/week (higher intensity) individual motor speech treatment for 10 weeks. Assessments were carried out before and after a 10-week treatment block to study the effects of variations in treatment intensity on the outcome measures.Outcomes &amp; ResultsThe results indicated that only higher intensity treatment (2x/week) led to significantly better outcomes for articulation and functional communication compared with 1x/week (lower intensity) intervention. Further, neither lower nor higher intensity treatment yielded a significant change for speech intelligibility at the word or sentence level. In general, effect sizes for the higher intensity treatment groups were larger for most variables compared with the lower intensity treatment group.Conclusions &amp; ImplicationsOverall, the results of the current study may allow for modification of service delivery and facilitate the development of an evidence-based care pathway for children with CAS.</p
