Yes / All neophyte contact lens wearers require training on how to handle contact lenses. Currently, almost no published information exists describing the most common approaches used by those involved in such training in soft contact lens wearers. This study aimed to gather information on the approaches taken by those conducting this training worldwide. An online survey was created in English and translated to Spanish and distributed internationally via social media, conference attendees, and professional contacts. The anonymous survey included information on workplace setting of respondents, information about the typical approaches used for application and removal of soft contact lenses, length of the appointment, and success rate with their approach. Survey responses were received between May 2021 and April 2022. A total of 511 individuals completed the survey and responses were received from 31 countries with 48.7% from the UK. The most common approach taught for application was to have the patient hold the upper eyelashes (84.7%) and to hold the lower eyelid with the same hand as the lens (89.4%). Lenses were applied directly to the cornea by 57.7% of the respondents. The most common approach taught for lens removal was to drag the lens inferiorly from the cornea prior to removal (49.3%). Most respondents did not use videos to aid the teaching appointment (62.0%); however, they felt that their approach was successful in most cases (90). Application and removal training sessions lasted a median of 30 min and contact lenses were typically dispensed after the instructor witnessing successful application and removal three times. Various methods are adopted globally for training of application and removal of soft contact lenses, with many advising a patient-specific approach is required for success. The results of this survey provide novel insights into soft contact lens handling training in clinical practice. / British & Irish University and College Contact Lens Educators (BUCCLE) receives sponsorship from CooperVision, Alcon, Bausch + Lomb and Johnson and Johnson.

Uppsatsens syfte har varit att utreda hur 3 kap. 3 § Ärvdabalken bör tillämpas. En efterlevandemake får inte genom gåva eller jämförlig handling utan tillbörlig hänsyn orsaka en väsentligminskning av den andel som kommer utgöra efterarv – om så har skett ska vederlag utgå tillefterarvingarna. Genom tillämpning av rättsdogmatisk metod har det framkommit det att enjämförlig handling exempelvis kan vara att sälja något till ett underpris, men att det finns fåexempel på jämförliga handlingar att hitta i rättskällorna. En handling har skett utan tillbörlighänsyn när en efterlevande make inte beaktat efterarvingarnas intresse fastän denne borde hagjort det. Av rättspraxis framkommer det att en väsentlig minskning i vart fall ska vara minst enfjärdedel av den andel som utgör efterarv. Om vederlag inte kan utgå till efterarvingarna kanåterbäring av gåvan eventuellt aktualiseras, men här finns en preskriptionstid som skulle kunnaförlängas för att stärka skyddet för efterarvingarna. Även ett stärkt skydd för testamentstagaresom efterarvingar har diskuterats i uppsatsen.

Thesis (MBA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Mobile lifter (ML) is a product that is used to lift loads or materials ranging from 20–600 kilograms (kg), and to move the loads to anywhere within the factory up to a height of 2.3 metres (m). The ML is ideal for loads heavier than human comfort, dangerous to touch by hands, requiring repetitive moving and not heavy enough for a forklift. As the need for labour rises and manufactures want to increase productivity, the ML becomes the solution. Currently, there is no company that specialises in ML, and that provides good service to the customers. HELM intends filling that gap in the markets. HELM plans to acquire exclusive distribution rights with a European base supplier of MLs. HELM will become the distributor of MLs in Southern Africa. HELM will have its base or office in Cape Town (CT), but also secure subcontractors in three other provinces, namely Gauteng, KwaZulu- Natal (KZN), and the Eastern Cape (EC). HELM will sell products from its supplier partner and it will offer services and a maintenance plan to its clients at a competitive rate. The ML can be used in manufacturing, wholesale, the retail trade and motor trade, and transport and storage. The three sectors account for over 35 percent of South Africa’s gross domestic product. The manufacturing sector is the largest sector with many industries. The most attractive industries are the fast moving consumer goods, automotive, pharmaceutical and chemical manufacturing industries. Although the industry or market is fragmented, Gauteng has the largest target market with over 9000 registered manufacturing enterprise. It is followed by KwaZulu-Natal, then the Western Cape and finally the Eastern Cape. The ML industry is still in its infancy, and HELM Solutions intend to sell 25 units in the first year, 33 in the second and then 36 in the third year. The current distributors of MLs only have one point of service per distributor in South Africa and MLs are non-core products for them. HELM also intends differentiating itself from other distributors by being a solution provider to clients, and not a product distributor. HELM wants to understand the clients’ business, understand their needs, and provide them with solution that will also increase their profit. This should give HELM a competitive advantage and make it difficult for clients to substitute the HELM products and service. Franck Tshilombo is one of the three entrepreneurs who will be directly involved in the business. He will start as the only employee of the business. He has been working with MLs for the past four years. His experience ranges from selling and marketing to ordering, assembling, service and maintenance of MLs. Kevin French brings experience in the financial field of investments. He holds a B Com degree and is a CFA charter holder. He has 25 years combined experience in financial services at large corporates and smaller entrepreneurial start-ups. He owns an investment management business and two paint distribution businesses. His experience includes starting new businesses, takeovers and turnarounds in financial services, and construction and electrical engineering. Collin Ramukhubathi who has a mechanical engineering degree and is an MBA candidate, has 15 years working experience in general management in construction and the mining sector. HELM Solutions require funding for fixed assets and working capital. The fixed asset will be funded by shareholders in the form of assets worth R30 000 and cash of R15 000. The amount of external funding required is R154 000. The desired funding should be in the form of an overdraft loan, as not all the funds will be needed in the beginning. This funding will be used towards the monthly expenses for the period of three months and towards increases in sales within the first five months. The funds will be needed during sales growth as the cash conversion cycle of the business is long. The overdraft loan is based on the interest rate of 12 percent. Based on these estimates, the loan will be fully repaid within 11 months.

Aim: More and more organizations worldwide want to develop products for global markets. At the same time, they need to make their products available in the global market to be competitive. One of today's trends to solve this problem of making products in the global market is by involving logistics to manage complex distribution requirements. Organizations have developed strategic alliances with companies all over the world to manage their logistics operations network. (www.chrobinson.com). My research was aimed at understanding the coordination of logistics activities at the terminal.   Method: I based my study on a combination of descriptive and exploratory type. As regards descriptive I presented my data collected in a descriptive analysis. Also I used the exploratory research to know exactly the implementation of logistics activities at Schenker's terminal and also to observe the activities, conduct interviews and administer questionnaires.   Result &amp; Conclusions: The major results of my findings revealed that the existing management procedure of the outbound logistics system at Schenker terminal which involves material handling, transportation, distribution, cross-docking, customer service and information systems could not be seen as lean and agile. This is because of the existence of many problems faced by the terminal such as congestion, flows inefficiencies, excess scrap, too much manual documentation,  delays in deliveries, damages, poor customer service, return goods, idle equipment (forklift and trucks) and personal and high cost of operations.   Suggestions for future research: The study is limited in the sense that it does not include the whole supply chain; the terminal is just a part in the supply chain and whatever problems that are encountered are not experienced in the whole supply chain. This could lead to a broader basis of a future research project.

A sociedade está cada vez mais dependente de sistemas embarcados, sendo que na grande maioria das vezes eles operam de maneira invisível aos seus usuários. Essa dependência torna esses usuários vulneráveis a riscos, devido às falhas que podem ocorrer. Essas falhas podem provocar perdas de vidas ou sérios danos materiais e financeiros. Devido a estes fatos, a qualidade destes produtos torna-se um ponto essencial para se ter um sistema estável, livre de erros e com todas as suas funcionalidades sendo executadas. De encontro a isso, a etapa de teste apresenta-se como indispensável e de relevada importância para a obtenção de um produto com uma boa qualidade. Devido ao alto custo de produção e energia gasto com testes, surge a necessidade de novos estudos, sobre diversificados métodos, para se testar um sistema embarcado. Neste contexto, este trabalho tem como objetivo apresentar os estudos iniciais do teste de um Sistema Operacional Embarcado (SOE), através de um estudo de caso focado na rotina de tratamento de exceção do eCos (Embedded Configurable Operating System), pois ela apresenta uma forte interação entre software e hardware, sendo que esta interação é um dos principais desafios encontrados no teste de um software embarcado. Com isso, este trabalho pretende dar o passo inicial para pesquisas relacionadas aos testes de um Sistema Operacional Embarcado. Após a análise dos experimentos, pôde-se notar que a principal característica do Sistema Operacional Embarcado eCos, a configurabilidade, é um ponto de dificuldade extra para a realização dos testes, pois exige um estudo detalhado do código do SOE, o qual é totalmente genérico, antes do planejamento dos testes, podendo ser gasto muito tempo nessa atividade. Outro ponto é que o teste torna-se totalmente dependente do hardware. Entretanto, os resultados experimentais apresentados para o estudo de caso do presente trabalho foram satisfatórios. / Society is increasingly dependent on embedded systems, which in most cases operate in an invisible manner to its users. This dependence makes the user vulnerable to risks due to failures that may occur. These failures can cause loss of lives or serious property and financial damage. Because of these facts, the quality of these products becomes a key point to have a stable system, free of errors and with all the features running. This testing is of essential importance to obtain a product with good quality. Due to the high cost of production and energy spent on tests, there is a need for further studies on different methods, to test an embedded system. In this context, this work aims at presenting the initial studies as the testing of the Embedded Operating System. The case study was focused on the exception handling routine of the eCos (Embedded Configurable Operating System), because it has a strong interaction between software and hardware, and this interaction is one of the main challenges encountered in testing embedded software. Therefore, this work aims at taking the first steps towards research related to testing an Embedded Operating System. After analyzing the experiments, it was noted that the main feature of the Embedded Operating System, eCos, the configurability, is an extra point of difficulty for the tests. It requires a detailed study of the code eCos, which is completely general, before the planning of tests, and could be spent much time in this activity. Another point is that the test becomes totally dependent on hardware. However, the experimental results presented for the case study of this study showed satisfactory.

The work deals with the analysis of transport and handling operations performed on specific agricultural farm. It is the handling and transport operations in the handling of grain and bulky materials. It also analyzes new trends in the marketfor transport and handling equipment. Based on these analyzes, was developed a proposal for the modernization of handling equipment and vehicles. Farm equipment was proposed appropriate means of transport and handling facilities,not only from a technical perspective, but also in terms of ecological and economic terms. For this reason, it was suggested some existing vehicles discarded, replaced with some new and straw at harvest to select a cost analysis to choose other means of transportation and handling due to changes in the way of the harvesting. In modernizing the proposed new transport and handling means for greater versatility, leading to the greater utilization, there by reducing unit costs.
