The question why the PLR was not introduced on a copyright basis is also discussed. The focus of this study is during the period of 1934-1956 and it is a literature-study.

Feromoninnehållande substansers inverkan på hjärtfrekvensen hos tjur :

During the last 50 years the production of milk per cow has increased. This has, however, been followed by a decreased reproductive performance. Shorter and more indistinct signs of oestrus make it harder for the Swedish farmers to discover when the cows are in oestrus. There is a need for ways to control reproduction. The use of pheromones could possibly provide means to satisfy this need.

A First Effort to Visualize Knowledge of a Region? A visualization of Öresund & Shenzhen in the perspective of Knowledge Innovation Zone

We have through our theoretical framework been able to create a simplified measuring tool for a KIZ; the S-TKL. We have found that the S-TKL is possible to implement on the Öresund Region but with some flaws. Even though the Öresund Region has implemented the mindset of a KIZ, accurate statistics are in some areas hard to find. We can also through our empirical findings say that it is difficult to use the S-TKL on Shenzhen. The data we have found gives a good indication of both of the regions.

Retentionsr?tt och Legal Pantr?tt: Tv? Rigida Begrepp i ett Flexibelt R?ttssystem? En studie om hur retentionsr?tt och legal pantr?tt kan hanteras med hj?lp av ett funktionalistiskt angreppss?tt

Possessory liens and legal liens are two securities that has been the subject of debate from legal scholars for quite some time. Possessory liens are often viewed as a weaker security compared to legal liens. However, upon closer examination it turns out that possessory liens in most cases provide the the same opportunity to sell the property withheld as security. This possibility makes possessory liens resemble, if not be identical to, legal liens. Both securities arise by operation of law and grant the right to both withhold and sell property in the event of non-payment.

Nominalfrasers inverkan på återvinningseffektiviteten i ett probabilistiskt IR-system

The purpose of this study is to examine the difference between three query strategies with respect to retrieval effectiveness. The thesis aims at examining how two types of noun phrases containing a modifier to the head word, which is a noun affect the retrieval performance with regard to recall and precision. The noun phrases in the thesis are of two types: 1) noun phrases containing a modifier to the head word (which is a noun) and which are not dictionary phrases (NF) and 2) dictionary phrases. Both types of noun phrases in this thesis contain at least two words. The queries were executed in Query Performance Analyser, QPA, containing the InQuery system and a sub collection of TREC-Uta documents with its topics.

To be able to respond to these questions, the pupils and the staff have been handed surveys and the principal has been interviewed.

Social fildelning på arbetsplatsen : Traditionell och social fildelning

This paper describes how files and information can be shared in organisations and workplaces. We studied and compared the traditional file sharing in Microsoft Active Directory and the Social file sharing that comes with Microsoft SharePoint Sites. We used qualitative studies based on interviews with system administrators, management and by our own observations to acquire the necessary data. Using independent research, we were able to analyze the data and show the general difference between the traditional and the social file sharing systems. Social file sharing enables the user to easily store and share files in a flexible online environment.

Tankar kring informationssökning: hur ser uppsatsstudenter på BHS på sin egen informationssökning?

The result was analysed with Roger Säljö?s theory about the sociocultural perspective about how individuals learn in relation to their context and the social practice that they act in. The following conclusions were drawn from analysing the result. The students didn?t really reflect over their information seeking behaviour.

En studie om införandet av expected loss model : - En mer tillförlitlig och relevant metod för nedskrivning av finansiella tillgångar?

Accounting has been critized for being one of the leading factors in the latest financial crisis. One of the primary problem areas was identified as delayed recogonition of losses on financial instruments. Consequently, a new impairment model is being developed and is to be namned expected loss model. The difference from the present model, incurred loss model, is that it takes losses into consideration on an much earlier level. Even though the model may be theoretically feasible, in practice it may implicate a number of issues.

Expansion av sökfrågor med Svenskt OrdNät som termkälla

The purpose of this Masters thesis is to examine the performance of queries that are expanded by synonyms and hyponyms from Svenskt OrdNät, the Swedish version of the Princeton WordNet. Four different types of queries were constructed: a baseline query S1, the baseline query expanded with synonyms S2, the baseline query expanded with hyponyms S3 and finally the baseline query expanded with the synonyms and hyponyms used in S2 and S3. The terms for expansion were picked by hand. The queries were executed in the Query Performance Analyser QPA, a tool used in IR education and in experimental IR research for analysing and comparing the performance of individual queries. 20 topics from the test collection GP_HDINF were chosen for the experiment.

En retorisk provokation : Om förolämpningar, satir och karikatyrer

When is it acceptable to make fun of religion, and when does it become disrespectful? On January 7, 2015, the headquarters of the French satirical news paper Charlie Hebdo was subjected to a terrorist attack that claimed the lives of 12 staff members, due to the publishing of caricatures picturing the prophet Muhammed. The reactions that followed the attack circled around two perspectives; the importance of freedom of expression and the obligation to show respect for certain institutions and traditions in society. How come the caricatures can elicit such completely different reactions? This is the question that this thesis uses as a starting point for the examination of the subject caricatures and satire.

In my resault is also evident thatthere is a big difference between the teachers at the schools how much time you devoteto xenophobia and right-wing extremism in teaching.The conclusions show that these differences largely depend on which group of students thatteachers have.The conclusions will also be that there are great similarities between the way teachers reasonabout how to deal with xenophobia and the means to do, they also are relatively similar..

Äggstockens normala storlek och struktur hos tik :

There are only a few published studies on the normal variation in ovary size in bitches. All of the previous studies have been made on the beagle breed. This study was performed on indian street dogs with the objective to measure ovaries and structures in the ovaries after ovariehysterectomy to decide if smaller dogs have smaller ovaries and how small and big they can be in the normal dog. The structures (follicle and corpus luteum) where also measured to get a maximum size for normal structures in the bitch. This information can be valuable when examining the ovaries of the bitch with ulstrasound.
