Abstract (sommario):

The objectives of this study were to evaluate the alleviating effects of the isoquinoline alkaloid berberine (BBR) on the energy balance (EB), glucose and insulin metabolism, and liver functionality in transition dairy goats, as reflected by blood metabolites and enzymes. Twenty-four primiparous Saanen goats were randomly allocated to four groups. Goats in each group received, ad libitum, the same basal diet during the pre- and post-partum periods of evaluation. Goats received daily0, 1, 2, or 4 g BBR (coded as CON, BBR1, BBR2, and BBR4, respectively). Dry matter intake (DMI) and milk yield were recorded daily. Blood samples were collected on days −21, −14, −7, 0, 7, 14, and 21 relative to kidding, and individual body condition scores (BCSs) were also recorded. Supplementation with either BBR2 or BBR4 increased (p < 0.05) pre- and post-partum DMI, increasing (p < 0.05) the intakes of net energy for lactating and metabolizable proteins. BBR2 and BBR4 increased (p < 0.05) post-partum milk production as well as fat-corrected milk (FCM), energy-corrected milk (ECM), and feed efficiency, indicating the alleviating effect of BBR on the negative energy balance (NEB) in transition goats. The daily ingestion of either 2 or 4 g BBR reduced (p < 0.05) plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) and increased (p < 0.05) the dynamic change in the liver activity index (LAI) and liver functionality index (LFI), implying its hepatoprotective effect on transition goats. Overall, the results suggest that BBR supplementation of at least 2 g/d may help to ameliorate insulin resistance (IR) and fat metabolism disorders initiated by the NEB in transition dairy goats.

Abstract (sommario):

The aromatic hydroxyaldehydes 3a-3g, 5a-5f, 8 , 10 can be prepared by the action of BCl3, BBr3 or trifluoromethanesulfonic acid, on the aryl formates 1a-1f, 4a-e, 7, 9 via Fries rearrangement. BBr3 is more effective than BCl3. The activating ability of BBr3 can be improved by addition of FeCl3. Rearrangements which are induced by trifluoromethanesulfonic acid can give rise to the formations of regioisomers, which might be different from the products formed when the reaction is performed with Lewis acids. The yields of the aldehydes are lowered by subsequent condensation reactions. This view was confirmed by the isolation of a condensation product, which was characterized as a dibenzo[a,j]xanthene derivative 6 by crystal structure analysis. For the Fries rearrangement of formyl groups a new mechanism is proposed. 2-Hydroxy-1-naphthaldehyde 5c can be obtained in good yield from formic acid, BBr3, and 2 -naphthol.

Abstract Peralkylated 2,3,4,5-tetracarba-mdo-hexaboranes(6) 1 react with boron tribromide, BBr3, via selective exchange of the alkyl substituent in 6-position to give the corresponding new 6- bromo derivatives 2 in quantitative yield. The 6-iodo derivatives 2(1) can be prepared in the same way using BI3. Treatment of the carbaboranes 2 with Li Et3BH leads to the 1,2,3,4,5- pentaalkyl-2,3,4,5-tetracarba-inido-hexaboranes(6) 3. 1,3,4,6-Tetraethyl-2,3,4,5-tetracarbaw do-hexaborane(6) 4 reacts with BBr3 via degradation of the carbaborane cage to give EtBBr2, and (Z)-1,4-bis [bis(dibromoboryl)]-3-hexene 5. A new bis(diethylboryl)-substituted dialkenyl(bromo)borane 8 was prepared, but attem pts failed to convert it into a 1-bromo- or 6-bromo-mdo-C4B2-carbaborane. Treatment of 1,1-dialkyl-3-diethylboryl-4-ethylstannoles 9 with a large excess of BBr3 also affords 5, whereas 6-bromo-l,3,4-triethyl-2,3,4.5-tetracarbamdo- hexaborane(6) 11 was isolated in low yield (<5%) from the reaction between 9 and BBr3 (slight excess)

Abstract (sommario):

An extremely bulky secondary amine, HN(Ar†)(SiPr3i) HL† (Ar† = C6H2{C(H)Ph2}2Pri−2,6,4) has been synthesised and deprotonated with KH in toluene, to afford the potassium amide [KL†(η6-toluene)], which was structurally authenticated. Reaction of this with BBr3 and AlBr3, reproducibly gave the crystallographically characterised amido bromo-borane, [L†B(H)Br], and aluminacycle, [AlBr2{κ2-C,N-N(H)(SiPr3i){C6H2[CPh2][C(H)Ph2]Pri-2,6,4}}], respectively, via ligand C–H activation processes. The known secondary amines, HN(Dip)(Mes) (HLMes) and HN(Dip)(Trip) (HLTrip) (Dip =2,6-diisopropylphenyl, Mes = mesityl, Trip = 2,4,6-triisopropylphenyl), have been structurally characterised, and deprotonated to give the in situ generated lithium amides, [Li(LMes)] and [Li(LTrip)]. Reaction of these with BBr3 and AlBr3 has given the amido group 13 element halide complexes, [LMesBBr2] and [LAlBr2(THF)] (L = LMes or LTrip), the crystal structures of all of which have been determined. Synthetic routes to two new bulky amidine pro-ligands, ArN = C(But)-N(H)Ar, Ar = C6H2{C(H)Ph2}2Me-2,6,4 (Piso*H) or C6H2Pr2i(CPh3)-2,6,4 (Piso″H), have been developed, and the compounds crystallographically characterised. Deprotonation of Piso″H gave the potassium amidinate, [K(Piso″)], which was reacted with BBr3 to give [(Piso″)BBr2]. Reaction of Piso″H with AlMe3 afforded [(Piso″)AlMe2], which, when treated with I2 yielded [(Piso″)AlI2], the crystal structure of which was determined. Reductions of all of the prepared amido and amidinato group 13 element(iii) halide complexes were attempted using a variety of reducing reagents, with a view to prepare boron(i) or aluminium(i) complexes. While these were not successful, this study does offer synthetic inorganic chemists a variety of new very bulky anionic N-donor ligands, and boron/aluminium halide complexes thereof, for use in their own research.

Abstract (sommario):

Dopant induced grain growth in LPCVD polysilicon films has been investigated using BBr3 as the diffusion source at 900 and 950 °C. TEM and sheet resistance measurements indicate rapid growth under such doping conditions. Results are compared with the grain growth observed during (a) PBr3 doping of similar films, and (b) during anneals in ambients containing 1% oxygen in nitrogen, similar to that used during BBr3 or PBr3 doping. The results clearly demonstrate the rapid grain growth induced by both types of dopants, although phosphorus is more effective in inducing this grain growth.

Abstract (sommario):

4,22-Dimethoxy[2.10]metacyclophan-1-yne was prepared by bromination of [2.10]metacyclophan-1-ene followed by the dehydrobromination of the bromine adduct with KOBu-t. Treatment of 4,22-dimethoxy[2.10]metacyclophan-1-yne with BBr3 in CH2Cl2 at room temperature led to the demethylation and a successive intramolecular cyclization reaction to afford a novel [10](2,9)-5a,11a-benzofuro-5a-bora-11-bromochromenophane in good yield. Similar treatment of a mixture of the corresponding meso- and dl-1,2-dibromo-4,22-dimethoxy[2.10]metacyclophane with BBr3 in CH2Cl2 under the same conditions described above afforded cis-4b,9b-dihydro[10]benzofuro[3,2-b]benzofuranophane in 83% yield.

Abstract (sommario):

This thesis undertakes the development, characterization and optimization of boron diffusion for silicon solar cells. Heavy diffusions (sheet resistance < 40 Ohm/square) to form a back surface field, and light diffusions (sheet resistance > 100 Ohm/square) to form oxide-passivated emitters were developed. Test structures and solar cells were fabricated to assess uniformity, lifetime and recombination effects due to the light and heavy boron diffusions. It was found that the growth of a thin ~200 ??, thermal oxide, during stabilization ??? immediately prior to the boron diffusion - was required to maintain high lifetime and reduce surface recombination (reducing the emitter saturation current density) for all boron diffusions. The heavy boron diffusion process was incorporated into the single side buried contact solar cell processing sequence. The solar cells fabricated had both boron diffused and Al/Si alloyed P+ regions for comparison. This research conclusively showed that boron diffused solar cells had significantly higher open circuit voltage compared to Al/Si alloyed devices. Fabrication of n-type solar cells, and their subsequent characterization by overlayed secondary electron image and the electron beam induced current map showed that the Al/Si alloy varied in depth from 5 to 25 micrometers deep. Methodology and characterization for light, oxide-passivated boron diffusions are also presented. This study yielded boron diffused emitters (sheet resistance > 100 Ohm/square) with low emitter saturation current. It was observed that this was possible only when the thermal oxidation after the boron diffusion was minimal, less than 1,000 ??. This was due to the segregation effect of boron with oxide, decreasing the surface concentration that in turn decreased the electric field repulsion of electrons from the surface. Device modelling of n-type solar cells is presented where the parameters of the modelling include the results of the light, oxide-passivated boron diffusions. This modelling shows n-type-base material with light oxide-passivated boron diffusion has higher potential conversion efficiency than forming a solar cell from phosphorous diffused p-type material.

Abstract (sommario):

Nitrogen containing heterocycles have always constituted a subject of great interest due to their wide presence in biologically important compounds so the development of efficient methods for the preparation of pyrrole derivatives and formation of new pyrrole-based heterocyclic compounds are an attractive goal in heterocyclic chemistry. In this study, starting from dimethoxytetrahydrofurane and amino acid esters, unsubstituted pyrrole derivatives, and treatment of amino acid esters with convenient chloroenones 1,2-disubstituted and 1,2,4-trisubstituted pyrrole derivatives were synthesized without racemization. Reaction of unsubstituted pyrrole derivatives with norephedrine toward inter- and intramolecular cyclizations give new interesting heteropolycylic compounds with oxazole-pyrrole-pyrazine structures. Study continued with cyclization reaction of these synthesized substituted and unsubstituted pyrrole derivatives with BBr3 and new bicyclic pyrrole derivatives were obtained in moderate yield.

Abstract (sommario):

Boverkets Byggregler, BBR, reglerar hur byggnader får utformas. Regelverket uppdateras med jämna mellanrum för att fortsatt hållas modernt i det förändrande landskapet inom byggindustrin. Rapporten fokuserar på denna förbättringsaspekt och har närmare studerat två regler inom BBR. Dessa är paragraferna 5:561 som innefattar de kriterier som följs vid brandsektionering och 5:61 vilket handlar om att motverka brandspridning mellan byggnader igenom att byggnader kan byggas på 8 meters avstånd. Urvalet av regler gjordes via intervjustudier med sakkunniga inom brandingenjörsverksamheter samt genom litteraturstudier av framförallt Syfteshandboken. För att få en förståelse av styrkor och svagheter inom BBR utfördes litteraturstudier av Modernare byggregler samt Framtidens byggregler. Genom analys av dessa publikationer visades det hur analytisk dimensionering är en positiv och önskvärd metod att bevara, det finns väldigt många olika typer av tillämpare med skilda kunskapsnivåer gällande brandreglerna, samt att det fanns en del missledande passager i BBR som gör det förvirrande för tillämpare att urskilja mellan föreskrift och allmänna råd. Tillämpare som saknar specifik utbildningen eller information gällande byggreglerna har nästintill inga andra alternativ än att hänvisa till experter inom branschen för att tillämpa analytisk dimensionering. Då det vid många tillfällen inte finns möjligheter att följa de allmänna råden och förstå vilka aspekter av föreskriften som ska täckas igenom att tillämpa dem för specifika byggen. Fokus i detta arbete därför varit att undersöka möjlighet till analytisk dimensionering för de utvalda reglerna och sedan ge förslag på förtydliganden och utökade möjligheter för att förenkla för tillämpare av regelverket. Från undersökningen framkom det att föreskrifterna för 5:561 och 5:61 främjar användningen av analytisk dimensionering då de inte innehöll detaljlösningar men det fanns vissa aspekter av de allmänna råden som kunde förbättras. Genom att undersöka historiken gällande reglerna och identifiera anledningarna till tidigare revideringar och syftena bakom dessa revideringar, kunde nya välgrundade förändringsförslag tas fram. Ett av dessa förslag är att öka förståelsen för tillämpare genom att introducera fler förklarande exempel som kan presenteras som en lista till paragraf 5:61 för att lättare förstå vilka gränser och möjligheter som kan appliceras för att upprätthålla lämpligt brandskydd mellan byggnader. För paragraf 5:561 har det vid många tidigare utgåvor av byggreglerna funnits en större tabell med fler val av brandtekniska installationer för att upprätthålla lämpligt brandskydd, medan dagens allmänna råd har en mindre lista med färre valmöjligheter. Detta innebär en reduktion av angivna alternativ och variationer av tillgängliga brandtekniska installationer. Det rekommenderas att återinföra en mer utförlig lista för att utöka valmöjligheter och förståelse för tillgängliga brandtekniska installationer. Rekommendationerna som anges måste testas för att påvisa konsekvenserna och fördelarna ifall dessa träder i kraft. Speciellt gäller detta värmestrålningsberäkningar för listan inom 5:61 sedan brandgasventilering för paragraf 5:561.
The focus and goal of the thesis were to establish how and what in the current regulations, BBR, of Boverket (The Swedish National Board of Housing, Building and Planning) should be revised in order to increase understanding or give more choices to the person trying to apply the rules. BBR is today the set of rules used when designing a building. These rules are repeatedly revised in order to be kept up to date with modern building standards. The report applied literature and interview studies in order to identify some of the many different rules in BBR, which was interesting to research further. The chosen rules were 5:561 and 5:61, and by mapping previously made changes and compare today's iterations of the rules to the previous ones, some stark differences between the rules could be noted. In order to know what to be revised in the chosen rules, specific aspects must be identified as beneficial or hampering. For specified aspects to be identified as beneficial and as such being kept for future editions of BBR, also finding what are the adverse aspects of the rules in order to change them. To do this, an analysis of the publications “Modernare byggregler” and “Framtida byggregler” was made. The outcome of this analysis resulted in the strong support for an aspect of the rules called “analytisk dimensionering” (performance-based design). This aspect is the ability for someone trying to apply the rules to be able to make alternative solutions instead of following the given examples. In conclusion, the report found both rules 5:561 and 5:61 to have flaws that could mainly be solved by making the rules easier to follow without opting for “analytisk dimensionering”. This could be achieved with the inclusions of more examples and extending the available options a user of the rules would have. For these changes to be applied correctly more research must be done in these specific applications, in order to reassure what the consequences would be.

Abstract (sommario):

Hundreds of individually rare, but collectively common Mendelian disorders result in visual impairment. One of these disorders is a heterogeneous syndromic form of retinal degeneration, Bardet-Biedl Syndrome (BBS). This disease is an autosomal recessive disorder characterized by retinal degeneration, obesity, learning disabilities, congenital anomalies, and an increased incidence of hypertension and diabetes. Typically, individuals with BBS experience vision loss during childhood leading to blindness by the third decade of life. At least fourteen genes (BBS1-BBS14) are reported to individual cause BBS. This thesis focuses on one of these genes, BBS3, with the overall goal of characterizig the function of BBS3 in terms of both syndromic and non-syndromic retinal degeneration using the zebrafish and mouse model systems. A member of the Ras family of small GTP-binding proteins, BBS3 is postulated to play a role in vesicular transport. A second highly conserved transcript of BBS3, BBS3L, has been identified and is expressed predominantly in the mouse and zebrafish eye. The eye-specific expression of BBS3L facilitates the dissection of BBS function in the retina independent of alterations to other tissues. To this end a Bbs3L knockout mouse was generated and histological analysis at 9 months reveals disorganization of the inner segments, indicative of retinal degeneration. To further evaluate the functional effects of BBS3 deficiency in the eye, an antisense oligonucleotide (Morpholino) approach was utilized to knockdown bbs3 gene expression in zebrafish. Consistent with an eye specific role, knockdown of bbs3L results in mislocalization of the photopigment green cone opsin and reduced visual function, but not abnormalities of the Kupffer's vesicle or delays in intracellular trafficking of melanosomes, both cardinal features of BBS in the zebrafish. To dissect the individual functions of BBS3 and BBS3L, in vitro transcribed wild-type human BBS3 or BBS3L RNA was co-injected with the bbs3 morpholinos. BBS3L RNA, but not BBS3 RNA, restores green opsin localization and vision. Moreover, only BBS3 RNA is sufficient to rescue melanosome transport, a cardinal feature of BBS in the zebrafish. Bbs3L knockout mice as well as a zebrafish bbs3 knockdown model demonstrate that BBS3L is both necessary and sufficient for retinal function and organization. This work was extended to humans by characterizing the A89V missense mutation in BBS3 that results in non-syndromic retinal degeneration. To evaluate the in vivo function of the A89V missense mutation in non-syndromic retinal degeneration and BBS, rescue experiments were performed in the zebrafish. Unlike wild-type BBS3L RNA, BBS3L A89V RNA does not rescue the vision defect seen with loss of bbs3 in zebrafish; however, BBS3 A89V RNA is able to suppress the cardinal zebrafish BBS phenotype of melanosome transport, similar to wild-type BBS3 RNA. These data demonstrate that the BBS3L A89V mutation identified in patients with non-syndromic retinal degeneration is critical and specific for the vision defect.

Abstract (sommario):

Byggbranschen står idag för 40 % av landets totala energianvändning varav 85 % av energin förbrukas i bruksskedet. Med hänsyn till den omfattande energianvändningen inom byggsektorn har branschen ett stort ansvar för att minska landets totala energiförbrukning. Teknik för att bygga energisnåla byggnader är långt framme, men används inte i så stor utsträckning som man borde. En anledning till detta kan vara att man bygger med en kortsiktig syn på investeringar och att den som bygger och förvaltar inte är samma part. Verktyg för att ta riktiga beslut ur ett långsiktigt ekonomiskt och miljömässigt perspektiv finns i form av livscykelkostnadskalkyler (LCC). Byggnader har lång livslängd och det är viktigt att man i ett tidigt skede vid projektering använder sig av de hjälpmedel som finns att tillgå.

Koldioxid är en stor bidragande orsak till den ökade växthuseffekten, för att byggbranschen i framtiden skall kunna minska de bidrag den genererar till atmosfären så är det viktigt att man tar fram metoder för hur man på ett riktigt sätt mäter koldioxidutsläpp från byggnader i bruksskedet.

Byggherren har en nyckelroll för vår samhällsutveckling varför det är viktigt att han/hon har kompetens för att fatta riktiga beslut ur ett hållbarhetsperspektiv. Idag kan i princip vem som helst vara byggherre oavsett kompetens.

Ett steg mot ett klimatsmartare byggande vore att ställa krav i Boverkets byggregler på att man vid projektering skall utföra en LCC kalkyl. Ett större individuellt ansvar för de faktiska koldioxidutsläpp som man bidrar med genom de beslut man tar vid en byggnation skulle kunna regleras i BBR genom att man utformade metoder för att mäta de faktiska koldioxidutsläpp en byggnad ger. Ett system med avgifter på de utsläpp man bidrar med skulle säkert medföra att man tänker till ordentligt innan man fattar beslut om hur en byggnad skall utformas. Ett krav på certifiering av landets byggherrar är rimligt med tanke på den betydelse han/hon har för samhällsutvecklingen.
