The aim of this thessis is heat treatment and choice of material for Woodworking optimalization. Industrial Knives in conjunction with company Pilana Tools Knives. Knives of this company are used in different parts of the world, among others in northern states too, where are working in extreme conditions about temperature low below of freezing point. That’s why was tested many samples in another working conditions.

ABSTRACT Comparative study of established test methods for aggregate strength and durabilityof Archean rocks from Botswana In the current situation, river sand is used for building of roads and as raw material forconcrete in Botswana. River sand is a finite resource and important to preserve as itacts as natural water purification, groundwater aquifer and protection against soil erosion.Mining of bedrock may be a good alternative to replace the river sand with crushed rock(aggregates) in concrete and as road materials.The main purpose of this thesis was to determine if the rock grain size can be usedas a parameter to indicate durability and rock strength. It was also of interest to find outif the grain size correlates with established technical analysis and strength test methods.This knowledge can be used as a prospecting tool when searching for new quarry sites inthe future.In this master’s thesis, rock samples from the Gaborone granite complex have beenanalysed to examine how established test methods and the mineral grain size correspondswith the rock strength. By comparing technical properties (Los Angeles (LA) value ,aggregate crushing value (ACV), aggregate impact value (AIV) and 10 percent fines aggregatecrushing test (10 % FACT)) with quantitative analysis (mineral grain size andmineral grain size distribution), it is possible to determine the mineral grain size correspondenceto rock strength. Generally the result show that more fine-grained granitesshow better technical properties than more coarse-grained granites. The calculated meangrain size show weak negative correlation to ACV value, and a positive correlation to LA-, AIV- and 10 % FACT values. Best correlation can be seen between mean grain size andLA values (R2= 0.61) and AIV values (R2= 0.58). Low mean grain size tend to give bettertechnical properties in form of lower LA- and AIV values. The cumulative distributioncurve show that a high concentration of very fine material or fine material tend to contributeto a lower LA value. The results indicate that equigranular rocks with low meangrain size contributes to good technical properties, but when it comes to uneven grainedrock more factors must be taken into account to estimate technical properties.

Social Entrepreneurship and Social Enterprises are an emerging trend. An increasing number of individuals are finding ways to address a social issue through their entrepreneurial skills. As well as increasing number of corporations and investing organizations are looking for ventures that address a social issue to fulfil their social responsibility. Thus, it is increasingly becoming important for the social entrepreneurs to measure and report their impacts to society in an accurate way. This research seeks to find out the challenges faced by social entrepreneurs while setting up social impact measurements in their ventures and the solutions adopted by them. Through a series of semi‐structured interviews with successful social entrepreneurs, this research collects qualitative data that increases the knowledge in this area and contributes in a better understanding of the challenges faced by social entrepreneurs. This research found that Theory Of Change is the most commonly used method and is preferred by practitioners as it is easy to implement. The research summarises the efforts it takes to implement the measurements, recommends best practices or advice to make impact measurement easier and useful. Also, a framework is developed that can be used in setting up measurements in a social venture.

Background - For the retail industry, the increasing adoption of e-commerce solutions have brought opportunities, but also challenges. As physical stores have to varied extent lost their importance, they can no longer solely compete on price or quality but can instead benefit from adopting an experiential marketing strategy. Experiential marketing acknowledges the consumer as rational and emotional, and focuses on how to engage the customer through value adding experiences. Swedish retailers face these challenges right now as an increasing share of all Swedish retail sales are made online. The body cosmetics industry makes up the second largest segment of Swedish e-commerce sales, but also holds some of the most prominent brands in offering store experiences, making it a competitive and interesting industry to explore from an experiential marketing perspective. Purpose - The purpose of this thesis is to explore how experiential marketing strategies impact customers’ perception of value within the body cosmetics retail industry in Sweden. The research fills a gap since no previous qualitative study has been made connecting experiential marketing with customer perception of value within this industry. Method - An exploratory study with and inductive research approach has been conducted to answer the research question. A multi-method qualitative research design, where the methodological triangulation builds on company and customer interviews, as well as observations to explore the topic and fill the research gap. The findings were analysed with an thematic analysis, in which the authors identified four themes. Findings and Conclusion - The findings result in four themes essential when using experiential marketing strategies to impact the customer’s perception of value; staff interaction, value co-creation, a unified strategy and a higher purpose. It is concluded that experiential marketing is a way in which companies positively can impact customer perception of value.
