The Appropriateness in Advice-Giving From a Cross-Cultural PerspectiveYasser Al-Shboul
This cross-cultural study investigates the differences in the perceptions of the appropriateness in advice giving in English between American English native speakers (AEL1) and Jordanian learners of English as a foreign language (JEFL). Data were collected using an adopted version of a Multiple Choice Questionnaire (MCQ) by Hinkel (1997). The questionnaire consists of eight situations that required advice giving or opting out to a peer acquaintance (equal status) and an instructor (higher status). Each situation was accompanied by three MC selections in random order: direct advice, hedge advice, and indirect comments. The fourth selection was an explicit choice for opting out that remained constant for all selections. Results revealed that both groups have the same perception of the social distance in the situations involving peer acquaintance and instructor. They, however, differed in the types of advice they showed as the appropriate choice. JEFL participants considered direct advice or hedge advice as appropriate option to be used with peer acquaintance and with instructors where in American culture the AEL1 participants found these strategies as least likely appropriate. The paper suggests EFL programs that promote awareness for JEFL on various appropriate conversational strategies in English. The results are expected to be useful information in cross-cultural comparison studies and other related areas.

This is a great guide to surge protection from Hager and if you would like Hager Surge Protection fitted to your Bypass Switches Input for mains one or two please call us on 0800 978 8988 or email sales@criticalpowersupplies.co.uk
Critical Power Supplies provide a range of surge protection kits that can be fitted to any of our bypass switches or consumer units to meet Amendment 1 of the 17th Edition.
The surge protection devices in the kit offer type 2 protection to the BS EN 61643 standard, to ensure conformity with the current edition of BS 7671.
Amendment 1 of the 17th Edition requires electricians to conduct a risk assessment of properties to see if they require surge protection.
When you consider that many homes have a lot of sensitive electronic equipment, such as TVs, Hi-Fis, PCs and printers that would be adversely affected by a voltage surge, then the need for such devices increases.
Transient overvoltages are not just caused by a direct lightning strike, a nearby strike, within a kilometre, can cause substantial damage. Other causes can be fluctuations in the power supply or from equipment such as microwaves or showers being switched.
Our surge protection kit can prevent the spread of overvoltages in electrical installations and protect the equipment connected to it. It is characterised by an 8/20us current wave.
To gain a greateer understanding of Surge Protection and our Surge Protection Kit & Devices download a copy of our Guide to Surge Protection Devices.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
