Knowledge Sharing Processes within a Women Empowering Network : A case study of Uganda
Boundaries in the growth of women entrepreneurship, in general, are for example family responsibility, gender discrimination, missing networks and the lack of interaction with other successful entrepreneurs. This is especially critical in developing countries where the women have to face additionally barriers. The existence of supportive organizations is crucial in creating opportunities for female entrepreneurship. One example of a female entrepreneurial network that supports women doing business is GSWIM (Grooming a Successful Woman with an Intellectual Mind), operating in Kampala, Uganda. This thesis will study the knowledge sharing behaviour within the organization. The main data collection has been retrieved through interviews held with five business women, members of GSWIM. A developed version of the MOA framework (Motivation, Opportunity, Ability) have been used to analyse the collected data. It is shown that there are a lot of things in GSWIM that facilitate the knowledge sharing behaviour. GSWIM motivate, inspire and are proficient in communicating the value of sharing knowledge. However, there are some crucial aspects for improvements related to increased ability, belongingness of members and decentralization. The long-term orientation is along with team cohesiveness, probably two of the networkâs major assets. By providing a network for women, and a platform for knowledge sharing, GSWIM has reduced some barriers to entrepreneurship in Uganda
Grid connection of a future electric road
The transport sector accounts for a third of Swedenâs total greenhouse gas emissions where cars and heavy trucks dominate the use of fossil fuels. The Swedish government is now intensifying the work for an electrified transport sector where electric roads could be an important part. Electric roads enable heavy vehicles to charge their batteries while driving, which is expected to contribute to environmentally friendly and time-efficient freight transports. To implement electric roads, availability of electric power along the electric roads will be required. This study presents a plan for connecting an electric road to the electricity grid in the electricity network area of Vattenfall Eldistribution. From the results, the idea was to present general conclusions from the experiences of the study, that could contribute in further implementation of electric roads. The road that has been selected for the study was the E4 between GaÌvle and Stockholm. A model for calculating the power demand along the electric road has been modeled and connection possibilities to transformer stations has been investigated. The analysis was based on three scenarios where different degrees of strengthening of the existing electricity network were assumed. In addition, a forecast for 2030 and a cost estimation for each scenario has been carried out. The result of the study indicates that for road sections close to larger cities, there are a larger number of connection options in comparison to rural areas. Furthermore, the designed solution in the study required strengthening of the electricity grid and the investment cost was 362 million Swedish crowns.

Electric vehicle charging in parking lots of multi-family houses
This bachelor thesis examines the possibility for electric vehicle charging in parking lots of multi-family houses. A case study is performed on two different housing areas located in Uppsala,Sweden. The capacity of the electric cables supplying the housing areas with power and the installation costs for the charging points is studied. The thesis is written in collaboration with Uppsalahem, which owns and maintains the housing areas. The areas have different parking possibilities. The investigated alternatives for charging are modifying internal  combustion engine pre-heating stations to charging points and building new charging points. The investigation is performed using a model made in MATLAB. The results show that for the first housing area, Sala Hage, it is possible to supply the parking lots, 60 in total, belonging to the area with charging points with the power of 2.3 kW or 11 kW. For installing 22 kW chargers, the capacity of the cable is sufficient for only 30 parking lots. For the other housing area Kastanjen, the required capacity of the cable for installing charging points on the 60 parking lots in the garage is 106.6 kW for the charging power 2.3 kW, 266.3 kW for the power 11 kW, and 460.2 kW for the power 22 kW. A sensitivity analysis on the results of the MATLAB model is made by changing the input parameters. The cost for upgrading the 43 parking lots in Sala Hage from the already installed internal combustion engine pre-heating stations to charging points is 292 400 SEK. To install 60 new charging points, the cost would be 4 920 000 SEK, a cost which is valid for both the housing areas

FemtoMAX - An X-ray beamline for structural dynamics at the short-pulse facility of MAX IV
The FemtoMAX beamline facilitates studies of the structural dynamics of materials. Such studies are of fundamental importance for key scientific problems related to programming materials using light, enabling new storage media and new manufacturing techniques, obtaining sustainable energy by mimicking photosynthesis, and gleaning insights into chemical and biological functional dynamics. The FemtoMAX beamline utilizes the MAX IV linear accelerator as an electron source. The photon bursts have a pulse length of 100fs, which is on the timescale of molecular vibrations, and have wavelengths matching interatomic distances (Ă
). The uniqueness of the beamline has called for special beamline components. This paper presents the beamline design including ultrasensitive X-ray beam-position monitors based on thin Ce:YAG screens, efficient harmonic separators and novel timing tools.The FemtoMAX beamline facilitates studies of the structural dynamics of materials on the femtosecond timescale. The first commissioning results are presented
Genome-wide association study of classical hodgkin lymphoma and epstein-barr virus status-defined subgroups
Background Accumulating evidence suggests that risk factors for classical Hodgkin lymphoma (cHL) differ by tumor Epstein-Barr virus (EBV) status. This potential etiological heterogeneity is not recognized in current disease classification. Methods We conducted a genome-wide association study of 1200 cHL patients and 6417 control subjects, with validation in an independent replication series, to identify common genetic variants associated with total cHL and subtypes defined by tumor EBV status. Multiple logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) assuming a log-additive genetic model for the variants. All statistical tests were two-sided. Results Two novel loci associated with total cHL irrespective of EBV status were identified in the major histocompatibility complex region; one resides adjacent to MICB (rs2248462: OR = 0.61, 95% CI = 0.53 to 0.69, P = 1.3 Ă 10(-13)) and the other at HLA-DRA (rs2395185: OR = 0.56, 95% CI = 0.50 to 0.62, P = 8.3 Ă 10(-25)) with both results confirmed in an independent replication series. Consistent with previous reports, associations were found between EBV-positive cHL and genetic variants within the class I region (rs2734986, HLA-A: OR = 2.45, 95% CI = 2.00 to 3.00, P = 1.2 Ă 10(-15); rs6904029, HCG9: OR = 0.46, 95% CI = 0.36 to 0.59, P = 5.5 Ă 10(-10)) and between EBV-negative cHL and rs6903608 within the class II region (rs6903608, HLA-DRA: OR = 2.08, 95% CI = 1.84 to 2.35, P = 6.1 Ă 10(-31)). The association between rs6903608 and EBV-negative cHL was confined to the nodular sclerosis histological subtype. Evidence for an association between EBV-negative cHL and rs20541 (5q31, IL13: OR = 1.53, 95% CI = 1.32 to 1.76, P = 5.4 x 10(-9)), a variant previously linked to psoriasis and asthma, was observed; however, the evidence for replication was less clear. Notably, one additional psoriasis-associated variant, rs27524 (5q15, ERAP1), showed evidence of an association with cHL in the genome-wide association study (OR = 1.21, 95% CI = 1.10 to 1.33, P = 1.5 Ă 10(-4)) and replication series (P = .03). Conclusion Overall, these results provide strong evidence that EBV status is an etiologically important classification of cHL and also suggest that some components of the pathological process are common to both EBV-positive and EBV-negative patients
