Jordbruk är avgörande för människans överlevnad och idag står det inför många problem relaterade till både klimatförändringar och en ökande befolkning. Medan ökande totalskördar under 1900-talet har skapat förutsättningar både för global ekonomisk tillväxt och för befolkningstillväxt, har de jordbruksmetoder som används ofta fört med sig negativa konsekvenser både för ekosystem och människor. JordAgriculture is essential for human survival and today it faces many problems related to both climate change and an increasing population. While increased total yields during the 20th century have created the conditions for both global economic and population growth, the agricultural practices utilized have often had detrimental consequences both for ecosystems and people. The agricultural sector i

Nigeria is, by population, the largest country in Africa and their economic growth will be a key part in the world reaching the goals of eradicating poverty. This paper investigates the economic growth performance of Nigeria and the relationship between oil and the GDP performance by using growth accounting, ARIMA, VAR and VEC models. Through the ARIMA and VAR models, the GDP is forecasted until 2

Alla fastigheter är unika, framförallt i avseendet att de inte är flyttbara och att de investeringar som görs är bestående. Trots de unika karaktärsdrag som följer med en fastighet sker de flesta värderingar med schabloniserade marknadsantaganden baserat på typ av fastighet, läge och värdeår. Följden blir att fastigheter med hållbara och miljövänliga lösningar värderas på samma sätt, och med likarAll real estates are unique, especially based on the fact that they are non-moveable and investments are long lasting. Despite the unique traits of character, most of the valuations are made using average market data, based upon the type of property, the location and the year of value. The consequence of using market standards is that properties with sustainable and environmentally friendly soluti

Aims: In a population of middle-aged women a survey was carried out to ascertain the prevalence of mental symptoms and psychotropic drug use, and further to investigate whether severe mental symptoms are associated with social situation, alcohol consumption, smoking, and physical health. Methods: All women (n510,766) aged 50-59 years and living in the Lund area were invited to the WHILA study, a h

BACKGROUND: The gold standard to reconstruct a nerve defect is a conventional autologous nerve graft. There may be a lack of such grafts in severe nerve injuries. Alternatives to autologous nerve grafts are needed. METHODS: We have developed a technique where mainly Schwann cells are acutely dissociated from the ends of the severed nerve trunk after nerve injury. The technique does not require lon

Heterocyclic amines are mutagenic/carcinogenic compounds that are found in cooked meat and fish. These compounds are of concern in the aetiology of human cancer and therefore it is important to minimise their formation during cooking, and their intake. PhIP (2-amino-1-methyl-6-phenylimidazo[4,5-b]-pyridine, CAS no: 105650-23-5) is one heterocyclic amine that is found at high levels in cooked chick

The entire cDNA corresponding to the C-terminal cysteine-rich domain of the human MUC2 apomucin, after the serine- and threonine-rich tandem repeat, was expressed in Chinese-hamster ovary-K1 cells and in the human colon carcinoma cell line, LS 174T. The C-terminus was expressed as a fusion protein with the green fluorescent protein and mycTag sequences and the murine immunoglobulin K-chain signal

Seventeen ETV6/RUNX1-positive pediatric acute lymphoblastic leukemias were investigated by high-resolution array-based comparative genomic hybridization ( array CGH), gene expression profiling and fluorescence in situ hybridization. Comparing the array CGH and gene expression patterns revealed that genomic imbalances conferred a great impact on the expression of genes in the affected regions. The

Objective: Individual-based studies on restricted geographical settings have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs) may precipitate congestive heart failure. As NSAID use is very extensive, it might increase the occurrence of symptomatic heart failure in the general population. Therefore, in order to study the impact of NSAID utilisation (prescribed and over the counter) on h

To study whether antibodies to glutamic acid decarboxylase (GADab) are associated with subclinical beta-cell damage and impaired insulin secretion, we screened 441 nondiabetic patients with autoimmune thyroiditis (AT) for GADab, and 15 (3.4%) were found positive. Antibodies to IA-2 were found in two GADab+ and one GADab- patients. We matched 11 GADab+ and 13 GADab- AT patients who were euthyroid o

Previous studies have suggested that depression increases the risk for diabetes and that this may be mediated through insulin resistance. The study aimed to analyze if self-rated symptoms of depression are related to insulin resistance among middle-aged and older Swedish women with features of the metabolic syndrome and being at risk for type 2 diabetes mellitus. We analyzed data from 1047 Swedish

OBJECTIVES: To assess the coexistence of hypertension and diabetes, associations with cardiovascular risk factors and the achievement of current treatment goals. DESIGN: A community-based, cross-sectional, observational study. SETTING: Hypertension and diabetes outpatient clinics in primary health care, Skara, Sweden. SUBJECTS: All patients (n = 1116; 488 men, 628 women) who performed an annual fo

The purpose of this study was to qualitatively examine, from a legal aspect in relation to the young persons protection needs, and analyze how the youth clinic staff handles their discretion regarding the contradiction between their duty to report and confidentiality in contact with young people under 15 who are sexually active. In the Sexual Crimes Act, it appears in several places that a child u

Enligt svensk familjerätt är syskons rätt till varandra varken en fastslagen lag eller utvecklad i förarbeten och doktrin. Trots detta föreligger det ett starkt skydd av syskon enligt praxis, vilken har sin grund i begreppet kontinuitet. Begreppet kontinuitet är ett resultat av främst praxis, men har sin grund i förarbeten. Denna har till syfte att behålla all slags pågående kontinuitet för barnetAccording to Swedish family law, the right for siblings to each other is not a stated rule, nor well developed in preliminary works or doctrine. However, there is a higher level of protection of siblings according to case law, which is anchored in the concept of continuity. The concept of continuity is mainly a result from case law, but has its ground in preliminary work. It aims to maintain all c

This report summarizes the advantages and disadvantages of organic and conventional farming from an environmental and sustainable perspective. A sustainable agriculture system needs to be able to meet a higher demand for food due to a growing population and minimize the damage of the environment at the same time. The main critic to the organic farming system is that it produces lower yields than

In this master thesis, combinations of noise-canceling LNA and harmonic-rejection mixers are investigated and compared to find an optimal inductorless receiver front-end for low-band (600-960MHz) FDD LTE-A network. The work was carried out in a modem development project at Ericsson Modems, Lund. Three receiver versions with different harmonic rejection techniques are compared in terms of noise fig

The factors behind the struggle for women’s empowerment in Iran are a combination of social, religio-cultural and traditional constraints. These have been institutionalized through the legal and legislative system, as well as the informal traditional practices in the public and private spheres. The Iranian legislative apparatus which directly and indirectly poses constraints on women’s presence in

Following a long-standing sociolinguistic pursuit to investigate language policy through complex non-linear models that analyze historical, structural, political and social processes that produce, contextualize, circulate and negotiate particular ideologies, beliefs and myths about languages and their values through meaning-making activities, this master’s thesis aims to apply an interpretive appr

Background: The rapid increase in type 2 diabetes worldwide has mainly been attributed to lifestyle factors, including poor eating habits and physical inactivity. Type and quality of diet is a key factor in both prevention and treatment of type 2 diabetes. Aim: To investigate the association between diet quality and risk of type 2 diabetes. Methods and Subjects: This prospective study in the M
