Abstract:
Aim. To conduct a detailed analysis of the causes of development of late stomal complications, to determine the indications for surgical correction, to evaluate the effectiveness of new methods of surgical treatment. Methods. Conducted was an analysis of the causes of late stomal complications in 141 patients with a stoma of the colon. Results. A parastomal hernia was diagnosed in 44 (31.2%), prolapse - in 29 (20.6%), stricture - in 9 (6.4%) patients. Introduced into practice were new methods of surgical correction of complicated stomas. Parastomal hernia was detected in 44 (31.2%) patients - 26 (59.1%) females and 18 (40.9%) males, all patients with this complication were older than 50 years, the age group 71-80 years included 43.5% of patients. Since 2005 performed were 17 reconstructive operations for parastomal hernias (Russian Federation patent №2406454 and №2395238). Stoma prolapse was observed in 29 (20.6%) patients, 10 cases - in patients aged 71 to 80 years. Most often this complication developed in patients with double-barreled transverse stomas - in 10 (76.9%) of 13 patients. 4 patients underwent surgery due to prolapse. Stoma stricture was diagnosed in 9 (6.4%) patients. In 7 patients with a stoma stricture in the early postoperative period registered was festering of the parastomal wound (4 cases), marginal necrosis of the stoma (2 cases), and stoma retraction (1 case). Correction with the use of stents for the prevention of recurrence (Russian Federation patent №2357681) was conducted in all cases. The so-called «lock-stoma» was diagnosed in 16.3% of cases (23 patients). Although this condition does not belong to stomal complications in its pure form, however in most cases it causes the inability to use the incontinence bag, reducing the quality of life. Conclusion. Despite the inevitability of the development of parastomal complications, provided proper surgical techniques can either prevent or delay their appearance; reconstructive operations for complicated stomas, conducted by moving the stoma to a new place with retroperitoneal conduction makes it possible to obtain satisfactory results, significantly improve the quality of life that promotes full social adaptation of stomal patients.

Abstract:
AbstractIleostomy or colostomy formation is an important component of many surgical procedures performed for a wide range of disorders of the gastrointestinal tract. Despite the frequency with which intestinal stomas are created, stoma-related complications remain common and are associated with significant morbidity as well as cost. Some of the most prevalent complications of stoma formation which will be detailed in this article include peristomal skin complications, retraction, stomal necrosis, stomal stenosis, prolapse, bleeding, dehydration from high ostomy output, and parastomal hernia. The authors will review these common complications, detail means to avoid or prevent them, and outline recommendations for management.

Abstract:
Background: Intestinal stoma is an opening for fecal diversion. The purpose of the present study was to identify indications for emergency laparotomy, commonly performed intestinal stomas and to study complications related to it.Methods: This is a prospective study was carried out in a surgical unit of Saveetha Medical College & Hospital, Chennai, Tamilnadu, from August 2012 to August 2013. Data was collected by meticulous history taking including age, gender, indication, type of stoma, type of surgery, careful clinical examination, appropriate operative findings and follow up of the cases. The results were collected, analyzed and compared.Results: A total of 74 patients were evaluated age ranged between 16 to 78 years. Male to female ratio was 7:2. The most common type of stoma made was loop ileostomy (60%) followed by end ileostomy (30%) and loop colostomy (9%). Main indication for emergency laparotomy was intestinal obstruction (44%). The most common type of stoma performed was loop ileostomy (60%). The most dreaded complication of stomal closure is anastomotic leakage.Conclusions: Early referral to the tertiary hospital, early diagnosis, proper preoperative management like intravenous fluids, antibiotics, etc., early detection and prevention of hypotension, reduction of time duration for emergency laparotomy, close post-operative monitoring definitely reduce the morbidity and mortality of stomal closure, when intestinal stomas kept for emergency cases.

Abstract:
Aim. To find an optimal way of end colostoma formation in patients with colorectal cancer following abdominoperineal extirpation of the rectum. Methods. Results of surgical treatment (rectum extirpation ended with sigmoidostomy) of 142 patients with malignant tumors of lower part of rectal ampulla treated from 2005 to 2012 are presented. Data of 101 patients (comparison group) were retrospectively analyzed, in whom the same approach of choosing the colostomy technique was applied. The main group consisted of 41 patients in whom the efficacy of authors-introduced technique of colostomy with alloplasty for colostomal wound consolidation from the abdominal cavity side was prospectively defined. Results. The prevalence of early post-operative stomal complications was 18,8% (in 19 out of 109 patients) in comparison group. Ileum volvulus around the stoma causing bowel obstruction was diagnosed in 2 cases, necrosis of stoma wall - in 2 patients, evisceration around stoma site - in 3 patients, perforation of sigmoid stoma - in 1 patient, stoma retraction - in 1 patient, bleeding at stoma site - in 3 patients, paracolostomal mass - in 1 patient. 14 patients from comparison group developed late post-operative stomal complications, including parastomal hernia - 8 patients, stoma prolapse - 3 patients, colostomal fistula - 1 patient, stomal stenosis - 2 patients. Treatment results in the patients from the main group were satisfactory. Early complications included 1 case of bleeding from stoma site, 1 case of partial necrosis of stoma wall. No late complications were registered. The gained data allows to provide successful rehabilitation to patients who underwent colorectal cancer surgery. The described technique is contraindicated in case of infected peritoneal effusion. Conclusion. The use of the method proposed by authors not only significantly improves colostomy results, but significantly decreases the rate of both early and late post-operative complications of stomas compared to standard methods.

Abstract:
Background: This study aims to provide an overview of all complications that may occur after construction of an ileostomy or colostomy (loop or end) for obstructing distal colorectal malignancy in emergency setting.Methods: It was a prospective observational study. Forty-eight patients were included in this study. Patients were divided into two groups, group (A) included patients with ileostomies (number of patients=24) and group (B) included patients with colostomies (number of patients=24).Results: Most common age group in both groups was >60 years, Peristomal skin irritation occurred in 33% of patients who have undergone ileostomy and 13% of patients who had undergone colostomy. 4% of patients who had undergone ileostomy developed retraction of the stoma. None of the patients who underwent colostomy developed retraction of stoma, 17% of patients who had undergone colostomy developed stomal prolapse; Stoma prolapse was seen in only 5% of patients who had undergone ileostomy.Conclusions: Stoma formation is a frequently performed surgical procedure. Ileostomy and colostomy are the most commonly made stomas in surgical practice. Ileostomies have slightly higher complication rate than colostomies. Peristomal skin irritation is the most common complication among all the complications. The second most common complication is stomal prolapse.

Abstract:
e15132 Purpose: Purpose is to prevent infection and subsequent complications following construction of either an Ileostomy or a colostomy in an elective or emergency operation. Technique is based on delayed-primary wound healing and established principles of basic sciences. Methods: Discovered by serendipity in 1986 during an Ileostomy, procedure was used for all stomata. Stomal (proximal) end of bowel (small/large) was left obstructed with staples and brought out at proposed site of stoma. Mesenteric corner was brought above skin opening. A cone was formed by lifting anti-mesenteric corner of bowel as apex of the stoma by pulling anti-mesenteric surface of bowel. Length of the stoma was determined by thickness of the abdominal wall. Serosa was sutured circumferentially to a round opening in rectus sheath starting below the mesenteric corner leaving an arc to accommodate the mesenteric vessels. This neutralized pulling effect of peristalsis on mesenteric corner of stoma and protects mesentery under skin reducing the chances of thrombosis of mesenteric vessels. Stoma was covered in OR using an appliance with transparent pouch. Obstructed stoma prevented immediate contamination of stomal and main wounds by feces. Postoperatively, serosal surface was covered by angiogenesis, making the stomal wound refractory to infection. When peristalsis returned, bulging stoma was opened using electro-cautery as a bedside procedure. Mucosal cuff protrudes and everts on angiogenesis over a single layer of serosa. Cuff progresses with peristalsis and grafts over a bed of granulation tissue. Margins of cuff adhere with dermis of skin opening completing self-maturation of stoma. Absence of sutures reduced tissue trauma and eliminated foreign body reaction resulting in better wound healing. This new scientific technique was named “DELAYED-PRIMARY SELF-MATURATION (DPSM)”. Results: 63 Colostomies and 17 Ileostomies were performed using DPSM. Infection in stomal and/or main wound was prevented. Subsequent complications were prevented. Conclusions: DPSM prevents infection and complications associated with Ileostomy and Colostomy operations. It is technically easier and more scientific than a conventional stoma. This technique is recommended for all cases requiring end/loop, temporary/permanent types of intestinal stomas. No significant financial relationships to disclose.

Abstract:
Patients in whom fistula speech has developed after laryngectomy usually have to occlude their stoma with a finger to talk. This prevents the air that is needed to activate the fistula from being exhaled through the stoma. In order to free the hand, Blom and Singer devised a diaphram-valved stomal device known as the tracheostoma valve. This device snaps into a flexible retention housing that must be carefully cemented to the skin. Some patients who have undergone near-total laryngectomy (and others with tracheo-esophageal voice prostheses) are unable to use their devices because the moisture and pressure around their stomas break the seal. Since air that is used to produce voice with the valve tends to lift the housing away from the stoma, a better housing design would assure that this motion would improve the seal.

Abstract:
Introduction Creation of gastrointestinal stomas is a common colorectal procedure associated with early or late complications, some of which demand advanced technical skills and expertise for optimal management. Case History A 63-year-old male underwent a defunctioning loop colostomy for locally advanced rectal cancer with liver metastasis. Three months later, he had developed a skinfold over his stoma that resulted in a horizontal skin crease traversing through the stoma, causing the stoma to ‘sink’ leading to obliteration of the stomal opening. This scenario led to ineffective attachment of a stoma appliance, resulting in painful peristomal ulcers. After excision of the anterior abdominal wall, assessment of colostomy opening was carried out, followed by closure of the subcutaneous tissues and drain fixation. An elevated colostomy with an adequate functional opening was seen after wound closure. The patient made an uneventful recovery and was discharged home. After 3 weeks, he had a fully opened, normally functioning colostomy and peristomal ulcers were almost healed. Conclusions This case highlights the challenges of stoma management, its related risks, avoidance of delay in chemotherapy, a patient wish for early return to work, and the novel approach we adopted to deal with these issues.

Abstract:
e20745 Background: Ileostomy/Colostomy operations are associated with a high rate of infections and complications resulting in increased morbidity, mortality and litigation. Pathogenesis of each complication and role of Nature was observed. Technique of stomal maturation was modified. Surgeon must maintain control over the stoma at all times. Primary maturation of stoma is unnecessary and potentially harmful. Opening stomal lumen in O.R. is unscientific and allows bacteria to contaminate stomal and main wounds. Methods: Concept was evolved by serendipity in April 1986. Since then it has been used on all patients requiring an Ileostomy or Colostomy. Bacterial migration is prevented by keeping the lumen obstructed. Iatrogenic obstruction of small/large intestine has no deleterious effect on post-operative course. Obstructed bowel is brought out of opening at proposed site of stoma. Mesenteric corner of obstructed stoma is always above the skin. Anti-mesenteric surface is pulled out till the anti-mesenteric corner becomes the apex of a conical stoma. Serosa is sutured to a round opening in the rectus sheath. Stoma is covered by an appliance with a transparent pouch. Peristalsis starts in about 48–72 hours. When obstructed stoma bulges, it is opened with electrocautery as a minor bedside procedure. Diet is started. Peristalsis pushes mucosal cuff which protrudes, everts and auto-grafts over angiogenesis. This is based on Delayed-Primary (DP) wound healing. Mucosal cuff comes in contact with dermis of skin opening at stomal site completing Self-Maturation (SM). During SM, mucosal tube separates from serosal tube. Peristalsis continues to exert its effect on serosal tube but not on mucosal tube. Lumen of stoma remains concentric. Results: 65 Colostomies and 15 Ileostomies were performed using DPSM technique. Infection and complications were prevented. Minor complications were handled easily. Patient satisfaction was excellent. Conclusions: Primary maturation of stoma is unnecessary and potentially harmful and should be replaced by DPSM. It can be performed in all types of stoma construction, end or loop, temporary or permanent. It prevents infection and complications in all patients.

Abstract:
Background: To find out a practicable, cost effective and easily available alternative of commercial stoma care devices for pediatric patients in a developing country.Methods: The study was conducted in the department of Pediatric Surgery in Dhaka Medical College Hospital, Bangladesh, during two years period from May 2009 to April 2011. Number of patients was 162 with age range 2 days to 7 years, mean age 2.3 years. As early as a colostomy or ileostomy had started functioning, a central hole was made in a betel leaf. The hole could just snugly accommodate the stoma. After applying a layer of zinc oxide paste over the peristomal skin the leaf was placed as such the stoma rotrudes through the hole. The smooth shiny surface of the leaf would face upwards and rough surface downwards. Another intact betel leaf with the shiny surface also facing upwards would cover the stoma. The leaves did not act as a reservoir rather simply acted as a barrier between the effluent and the peristomal skin. Fifty seven patients with colostomy and 11 with leostomy used stoma appliances (wafer with bag). Eighty six patients with colostomy and 8 patients with ileostomy used betel leaves and zinc oxide paste. Mean length of time between creation and closure of a colostomy was 9 months and that of an ileostomy was three months. It was ensured that each individual patient had used his or her respective stoma care method till closure of the stomas. Two parameters were used to evaluate the outcome of the above mentioned stoma care methods: (a) peristomal skin excoriation and (b) insultto the stomal mucosa in the form of ulceration.Results: Among the patients who used stoma appliances 21.53% developed peristomal skin excoriation, 7.69% developed mucosal ulceration and 6.34% patients developed local hypersensitivity reaction to stoma adhesive. On the contrary, patients who were managed with betel leaves 20.93% developed peristomal skin excoriation and 8.13% developed mucosal ulceration. No incidence of allergic reaction to local application of betel leaf and zinc oxide occurred. Average cost for betel leaves was less than 0.50 US$ per month in comparison to about 30 US$ for ostomy appliances.Conclusion: Betel leaves may be used as a cheap, easily available, non irritant and effective alternative of commercial appliances to protect the stomas and peristomal skin in pediatric patients.DOI: http://dx.doi.org/10.3329/jpsb.v1i2.19534

<p>Sammanfattning</p><p>Detta arbete baseras på nybyggnationen och ombyggnationen av skolan i Hagfors som NCC gör för Hagfors kommun. Uppgiften är att göra en jämförelse av olika stomalternativ; platsgjuten betong, prefabricerad betong och stålstomme på nybyggnationen med hänsyn till tid, ekonomi och miljöpåverkan. Den nybyggda delen kommer att bli ca 7000 m2 fördelat på tre plan och stommen utgörs i dagsläget till största del av prefabricerad betong.</p><p>De frågeställningarna som behandlas i arbetet är</p><p>• Vilket material är mest fördelaktigt utifrån ett tidsperspektiv?</p><p>• Vilket material/stomlösning är ur ett ekonomiskt perspektiv att föredra?</p><p>• Hur påverkas miljön av de olika stomsystemen?</p><p>Målet med examensarbetet är att välja den mest lämpliga stomlösningen för nybyggnationen av Visa Bildningscentrum i Hagfors på uppdrag av NCC, ur ett ekonomiskt och tidsmässigt perspektiv. De alternativ som ska undersökas och jämföras är stålstomme, prefabricerad betongstomme och platsgjuten stomme.</p><p>Syftet med arbetet är att kunna få en inblick i hur olika stomsystem utformas, vilka byggmetoder som används, samt göra en jämförelse av stomsystemen som kan generera en relevant slutsats. Vi ska studera ett objekt där stommen redan är vald för att på så sätt få en mer verklighetsanknuten förståelse för problematiken vid val av stomme.</p><p>Problemlösningen baseras på laster, pelardimensioner, balkdimensioner, antal pelare och balkar. Dessa har tillhandahållits av NCC. Beräkningar genomfördes för att specificera armeringsmängd i betongstommarna och för att dimensionera stålstommen. För att se vad de olika stomalternativen kostade användes BidCon för att få fram en kalkyl på stommen, inklusive material och arbetskostnader. Resultatet av detta blev att den platsgjutna betongstommen kostar 4 104 000 kr, stålstommen kostar 5 835 000 kr och den prefabricerade betongstommen kostar 4 558 000 kr.</p><p>Om man ska se till tiden är det den prefabricerade betongstommen som tar kortast tid vid förutsättningen att leveranser och samordning sker planenligt. Den platsgjutna stommen är den mest tidskrävande bland annat beroende på långa uttorkningstider och faktumet att platsgjuten betong är mycket väderberoende.</p><p>Sett utifrån ett miljöperspektiv föll valet på att använda betong på grund av lägre energiförbrukning och utsläpp vid tillverkning, jämfört med stål, samt att en byggnad i betong har en stor värmetröghet vilket skapar förutsättningar för ett lägre och jämnare energibehov i den färdiga byggnaden. Transporter till byggplatsen har även betydelse på grund av att de prefabricerade betongelementen i detta fall tillverkas i och levereras från Tyskland.</p><p>Vid tillverkning av prefabricerade element minimeras de flesta problem som väder orsakar vid användning av platsgjuten betong. All produktion sker inomhus i fabriker och förutom att problem på grund av väderförhållanden försvinner så minskas även olycksrisken. Prefabricerat byggande har dock nackdelen att det är mycket störningskänsligt på grund av att det förlitar sig helt på att logistiken fungerar utan några förseningar. Problem med arbetsmiljö, exempelvis belastningsskador och olycksrisker, kan man flytta från byggarbetsplatsen till en fabrik där arbetsmiljön kan kontrolleras på ett bättre sätt genom att välja en prefabricerad stomme, även om man inte helt kan undvika dem.</p><p>I rapporten finns exempel på hur beräkningar genomförts, kalkyler på stålstommen och den platsgjutna betongstommen och ritningar på nybyggnationen.</p><p>Arbetet utförs på uppdrag av NCC med Bo Rom och Thomas Boman som externa handledare.

Abstract:
The objective of this report is to evaluate why wooden frameworkis not used more frequently in larger buildings when both contractors and clients profile themselves as environmental friendly, with future goals of becoming neutral to the environment. The biggest incentive to build more with a wooden framework is how the choice of material impacts the climate and work environment at the construction site. It is hard to put a financial value on the benefits for the climate and work environment that a wooden framework provides. This is one of the reasons why the wooden frame is being neglected in the bidding process because it is often more expensive at that point in the construction process. Construction industries around the world has a large negative impact on the climate and greenhouse effect and contributes to 40 % of the global carbon emissions. Statistics show that the manufacturing of concrete and steel products used in constructionemits more than twice as much carbon dioxide as wood-based materials. Wood-based materials binds carbon dioxide during its life span and releases it when the product is obsolete. Many consider the healthier work environment as a very significant benefit of building with a wooden framework, especially theconstruction workers themselves. A healthy work environment forthe construction workers increase well-being and efficiency at the construction site. Project management is easier when the work situation for the construction workers is prosperous. The wooden framework contributes to a healthier workplace and reduces dust, vibrations from machines and noise considerably, the air is also cleaner and it has a better smell to it. Buildings with wooden framework is often being built under a tentof some sort to prevent moisture and rain to penetrate the building causing damage. The tent itself is very expensive tobuild under, and it’s a major reason why framework made of wood is more expensive in the bidding process. Contractors supplying framework-systems made of wood are constructing the building in the same way a steel and concrete frame would be constructed, without materials sensitive to moisture. The wooden frame dries out faster than a frame made of steel and concrete. If the two prefabricated systems are assembled in a similar way the wooden framework can better compete on equal terms with other framework systems in the bidding process. The crucial part for an increased usage of wooden frameworks in commercial office buildings is that the contractors and clientsreach a turning point. A turning point in which they accept that the wooden framework appears more expensive in the bidding process but yet they choose it because of the benefits it provides. Only then can the right circumstances be achieved, which leads to an increased use of wooden frameworks in the market.<br>Målet med den här studien är att göra en utvärdering på varför det inte byggs fler större projekt med en trästomme när både entreprenörer och beställare har högt uppsatta framtida miljömål och vill profilera sig som miljömedvetna. De starkaste incitamenten för att bygga mer i trä är hur materialvalet påverkar klimatet och arbetsmiljön på arbetsplatsen. Det är svårt att sätta ett värde i pengar på miljö och arbetsmiljö, vilket är en av anledningarna till att ett stomsystem i trä ofta väljs bort i anbudsskedet då kalkylen för en trästomme ofta påvisar att trästommen är dyrare i den delen av byggprocessen. Världens byggindustrier har en stor negativ klimatpåverkan på växthuseffekten och står idag för 40 % av de globala koldioxidutsläppen. Statistik visar att framställningen av betongprodukter och stålarmering står för mer än dubbelt så stora utsläpp koldioxidutsläpp som träbaserade material. Träbaserade material binder koldioxid under sin livstid och avger det när produkten är förbrukad. Ett träbaserat material avger aldrig mer koldioxid än den binder under sin livscykel och har därmed en neutral påverkan på klimatet. Många upplever arbetsmiljön som en stor fördel med arbetet i en trästomme, framförallt yrkesarbetarna. En sund arbetsmiljö för yrkesarbetare ökar trivsel och effektivitet i projekt. Projektstyrningen underlättas när yrkesarbetarnas välmående och arbetssituation är så bra som möjligt. Att bygga hus med trästomme medför färre arbetsmoment och är förebyggande mot vibrationsskador orsakade av förborrning och användande av hårt vibrerande maskiner som slagborrar och bilmaskiner. En trästomme minskar damm och buller avsevärt, samt att luften är renare och det luktar fräscht. Trähus byggs ofta under väderskydd eller tält för att förebygga mot regn och byggfukt som kan medföra fuktskador. Det är dyrt att resa stomme under tält med traverskranar och det är en stor anledning till att trästommar är dyrare vid stomresning. De träentreprenörer som levererar och monterar trästommar har börjat resa trästommen till byggnader utan fuktkänsliga trämaterial till att huset är tätt. När huset är tätt torkar byggnaden ut fortare än ett hus av betong och invändiga arbeten med fuktkänsliga material kan påbörjas. När en trästomme monteras på samma sätt utan tält som en stålstomme med betongbjälklag blir den mer konkurrenskraftig i anbudsskedet. Det som är avgörande för utökat användande av trästomme i kommersiella kontorsbyggnader är att entreprenörer och beställare kommer till en brytpunkt. En brytpunkt där de accepterar att trästommen ser dyrare ut i anbudsskedet men ändå väljer den på grund av de positiva effekterna på arbetsmiljö, brukarupplevelse och långsiktig hållbarhet. Först då kan rätt förutsättningar skapas för att trästommen ska bli mer konkurrenskraftig mot övriga marknaden.

SÄBO AB will construct a sports Centre in Säffle municipality, the sports Centre will be used for football practice and the outer dimension of the sports Centre was determined to be 40x70 m.   The purpose was to demonstrate price and carbon dioxide emissions for the production of glulam and steel frames, the cross-laminated timber, CLT, and Paroc curtain wall. This was done by dimensioning the frames according to the Eurocodes and generate producing prices for the materials, also a calculation was made for carbon dioxide emissions for the alternatives in terms of transport and production. To calculate a key figure for earned carbon dioxide per invested capital, the differences could be more clearly demonstrated. Another aim was to produce a design proposal.   The glulam frame consists of glulam columns with three-joint truss in glulam, drawstick and windstrut in round steel. The roof trusses have a span of 40 m and the ceiling height indoors is 7.5 m. This frame became the most expensive but more beneficial in terms of carbon dioxide emissions for production.   The steel frame consists of HEA columns and saddle framework as roof, the roof trusses have a span of 40 m and the ceiling height indoors is 7.5 m. This frame was the cheapest but has the largest emissions of carbon dioxide from the production.   The curtain wall of CLT released the least carbon dioxide but became the most expensive alternative, the curtain wall of Paroc became the cheapest option but released most carbon dioxide from these two alternatives.<br>SÄBO AB skall uppföra en hallbyggnad i Säffle kommun, hallbyggnaden ska användas till fotbollsutövning och storleken på fotbollsplanen kommer vara en 7-mannaplan. Yttermåttet på bollhallen bestämdes till 70 x 40 meter.    Målet var att påvisa pris och koldioxidutsläpp för framställning av limträ- och stålstomme, och utfackningsvägg av KL-trä samt av Paroc. Detta gjordes genom dimensionering av stommarna enligt eurokoderna och genom att priser togs fram för materialen, även en beräkning gjordes för koldioxidutsläpp för alternativen vad gäller transport och framställning. Genom att ett nyckeltal för tjänad koldioxid per investerat kapital togs fram kunde skillnaderna påvisas på ett tydligare sätt. Ett ytterligare mål var att ta fram ett gestaltningsförslag.    Limträstommen består av limträpelare med treledstaktolar i limträ, dragband och vindstag i rundstål. Takstolarna har en spännvidd på 40 m och den fria takhöjden inomhus är 7,5 m. Denna stomme blev dyrast men mer fördelaktig vad gäller koldioxidutsläpp för framställning.    Stålstommen består av HEA-pelare och sadelfackverkstakstolar, takstolarna har spännvidden 40 m och den fria takhöjden inomhus är 7,5 m. Denna stomme blev billigast men har det största utsläppen av koldioxid från framställningen.    Utfackningsväggen av KL-trä släppte ut minst koldioxid men blev det dyraste alternativet, utfackningsväggen av Paroc blev således det billigaste alternativet men släppte ut mest koldioxid av dessa två alternativ.

Abstract:
Idag förbrukas jordens resurser i högre takt än vad jorden klarar av att bearbeta. Byggbranschen tillhör en av de sektorer som har högst klimatpåverkan, främst i form av koldioxidutsläpp. Därför pågår ett kontinuerligt arbete med att ta fram byggnadsmaterial som skall minska belastningen på miljön.  I byggbranschen kan man se en trend att korslimmat trä (KL-trä) blir allt mer efterfrågat som stommaterial. Det sägs ge upphov till mindre miljöpåverkan samt ge ett bättre inneklimat än vad andra stommaterial gör.   Denna studie visar en teoretisk jämförelse av klimatpåverkan samt av inomhusmiljön mellan en KL-trästomme och en kombinerad stål- och betongstomme. Båda stomalternativen har projekterats av ByggDialog tillsammans med deras samarbetspartners. Referensbyggnaden är Regnbågens förskola i Årjängs kommun. Syftet med denna studie är att uppmärksamma, skapa en medvetenhet samt ge verktyg till ByggDialogs kunder för att göra ett klimatsmart stomval, vilket i sin tur också kan bidra till att de svenska hållbarhets målen uppnås till 2030. Klimatpåverkan beräknades under produktskedet vilket innebär råvaruförsörjning, transport och tillverkning för ingående material (modul A1-A3) med hjälp av ett Global Warming Potential-värde (GWP-värde). Vilket är ett värde på hur stor klimatpåverkan ett material ger upphov till i form av utsläpp av koldioxidekvivalenter. För att undersöka hur stomval påverkar inomhusmiljön gjordes en litteraturstudie.   Resultatet visade att KL-trä som stommaterial gav upphov till cirka hälften så stor miljöpåverkan vad gäller koldioxidutsläpp men var cirka 12% dyrare att uppföra jämfört med en kombinerad stål- och betongstomme. Vid beräkning av koldioxidutsläpp per SEK visade det sig att en stomme av KL-trä hade cirka 67% lägre koldioxidutsläpp per SEK än vad en kombinerad stål- och betongstomme hade.  Litteraturstudien visade att KL-trä som stommaterial gav en jämnare luftfuktighet men sämre värmelagringsförmåga och ljudabsorption i form av steg- och stomljud jämfört med en kombinerad stål- och betongstomme. Forskning visade att synligt trä till exempel KL-trä, ger en upplevelse av trygghet, avkoppling och allmänt välbehag för människor som vistas i byggnaden.<br>Today, the Earth's resources are used at a higher rate than the Earth can manage. The construction industry is one of the sectors that have the greatest negative climate impact, mainly related to high carbon dioxide emissions. This industry continuously strives to develop building- and construction materials resulting in an as low  environmental footprint as possible. Recent trends, in the construction industry, shows an increase in the use of cross-limbed timber (CLT) for frame material. The claim is lower environmental footprint at the same time as it gives a better indoor climate compared to other frame materials.  This study will be a theoretical comparison of the climate impact as well as the indoor environment between a CLT frame and a combined steel and concrete frame. Both frame alternatives have been designed by the construction company ByggDialog together with their partners. The reference building for this study is Regnbågens Preschool in Årjäng Municipality. The purpose of this study is to raise and create awareness and also provide tools for ByggDialog and their customers enabling a climate-smart frame selection. This will most likely also  contribute to achieving the Swedish sustainability goals by 2030. By using data from the Global Warming Potential (GWP) for the input materials, the climate impact was calculated. Each construction frame type data was analyzed during the product phase which include raw material supply, transport and manufacturing (module A1-A3) in the form of emissions of carbon dioxide equivalents. A literature study was also conducted to analyze how a frame of CLT affects indoor environment.  The result showed that by using a CLT frame material versus a combined steel and concrete-frame the environmental reduction was about 50% and about 12% increase in cost. When calculating the carbon dioxide emissions per SEK, it was found that the CLT frame construction had about 67% lower carbon dioxide emissions per SEK compared to a combined steel and concrete frame. The literature study showed that a frame material of CLT provides a more evenly distributed humidity, poorer heat storage capacity and less sound absorption capacity in the form of step- and frame sound compared to a combined steel and concrete frame construction. Further research in this field indicates that by having visible wood, for example a CLT frame provides an experience of safety, relaxation and general well-being for people in the building.

Abstract:
Stomata are pores found on the epidermis of most aerial parts of plants and are formed by a specialized pair of cells, the guard cells. Stomata enable the uptake of CO2 in expense of water vapour release and therefore optimize the trade-off between transpirational water loss and carbon gain. Regulation of gas exchange is achieved by controlling the stomatal pore aperture involving the osmotic solute accumulation. Fluxes of K+ are mediated by the plasma membrane inward and outward rectifying K+ channels (KIN and KOUT), while the anion channels enable Cl- fluxes. Stomata in most plants follow the �one cell spacing rule� implying that the separation of stomata by at least one epidermal cell. However, there are several genera exhibiting stomata clusters, such as the genus Begonia. In this study I have used two Begonia species as well as Arabidopsis stomatal patterning mutants to explore the impact of stomatal clustering in plant physiology. In the tmm1 mutants the stomatal movements suppressed gas exchange responses when plants were exposed to light and darkness. Kinetic analysis of the K+ channels uncovered changes in the gating characteristics that affected the activity of KOUT channels as well as the voltage-dependence of KIN channel opening. Tail current analysis of K+ channels demonstrated that the effect was to reduce accumulation of K+ ions in the cytosol of guard cells from tmm1 plants. Raising light intensity and lowering evaporative demand enhanced WUE and growth of plants exhibiting single stomata, albeit the tmm1 mutant plants failed to respond likewise. Astonishingly, the tmm1 mutants were more resilient to prolonged drought stress via minimizing the transpirational water loss. Phenotypic analysis also revealed that the impaired stomatal behaviour of the tmm1 plants attenuated root growth under sucrose abundant conditions. I have also made use of the novel gasotransmitter hydrogen sulfide (H2S) to examine its effect on stomata. H2S-induced stomatal closure in both Arabidopsis and tobacco plants was dependent on the exclusive inhibition of KIN channels. The data implied a partial sensitivity of H2S effect to the intracellular Ca2+ levels, and modelling also suggest a role for pH in the H2S-mediate response. The tmm1 mutants did not respond to H2S in a wild type fashion, indicating that stomatal movements are altered irrespectively to the nature of stimuli. Collectively, my data suggest that stomatal spacing and their associations with neighbouring epidermal cells is important for the K+ relations of guard cells and their capacity to drive stomatal movements. The role of spacing was crucial for gaseous exchange as well as plant growth under favourable conditions. The data also provided novel insights into the network governing stomatal behaviour and positioned H2S to an independent branch of the ABA pathway. Finally, the data suggested an adaptive role for stomatal clustering under water-limited habitats and a potential use of H2S as a tool to minimize transpirational water loss.

Abstract:
The benefits of physical activity for cancer survivors are numerous and well-substantiated. However, it is unclear how to accommodate specific cancer treatments, such as a stoma as part of treatment for rectal cancer, in order to be physically active. To bridge this gap, this study undertook an interpretive phenomenological analysis to explore the experience of 15 rectal cancer survivors' engagement in physical activity with a stoma. Overall, three themes were found: 1) understanding the drive and the motivation to be physically active, 2) despite being motivated to be physically active with a stoma it can be challenging, and 3) how to be physically active with a stoma: lessons learned. The findings suggest rectal cancer survivors with a stoma require motivational support and enhanced competence and self-efficacy in order to engage in greater physical activity. Incorporating these skills into current information and supportive services targeting rectal cancer survivors with a stoma may help promote physical activity in this population.

Abstract:
(1) What is the relationship between stomatal responses and the rate of photosynthesis? The COa flux density and stomatal conductance are closely correlated, but there is not a simple causal link between them. This relationship is complex, and depends on both parallel but independent responses to light of stomata and photosynthesis, and indirect response of stomata mediated by photosynthesis. This indirect response occurs through CO2 depletion in the air spaces of the mesophyll and stomatal response to CO2- No evidence was found in favour of the proposed effect of photosynthesis on stomata through an unknown messenger. (2) What is the nature of the interaction between stomatal responses to humidity and temperature? The hypothesis that these responses are brought about by a single response to relative humidity at the leaf surface was tested, and shown to be incompatible with the responses of Hedera helix. It is suggested that the most appropriate variable for expressing humidity is, in this context, the water vapour deficit at the leaf surface. (3) What is the role of the boundary layer in the control of stomatal opening? Real world and simulation experiments were used to show that responses to bulk air vapour and COa mol fractions are both dependent on stomatal responses to CO2 and humidity. It is also shown that a feedforward response to humidity requires feedback through another variable for stability under natural conditions. Response to wind speed is due to changes in humidity and CO2 mol fraction at the leaf surface. (4) Are our current knowledge, and the resulting models, good enough for predicting short-term stomatal responses to changes in the environment? The need for a careful analysis of simulation models is stressed. Ball's empirical model of stomatal conductance was analysed. The original interpretation was found to be flawed, and a new one was proposed. The new interpretation views the model as a description of the relationship between COj flux rate and stomatal conductance, rather than of stomatal conductance alone. It is shown that this model is useful for describing the behaviour of the intercellular COj concentration. The model, was tested against data from the experiments. It was found that the responses to temperature and humidity are not treated in a satisfactory way. The response of the model to other variables is realistic. A modification to the model is described and tested. It is concluded that the model is a good starting point for the development of simulation models to be used as submodels in canopy and regional models.

Abstract:
Development is the result of a series of division, expansion and differentiation events, and the relationship between these events drives characteristics such as organ size and shape, patterning of tissues, and placement of specialised cells. Varying the rates of division, expansion and differentiation allows for plasticity in development. This plasticity means that there are often several routes to the same developmental outcome: for example, increasing cell division will increase the distance between specialised cells or increase organ size, and so will increasing cell expansion. Hence, a question arises: why do plants maintain a certain size or cell placement through a specific route, such as increasing cell expansion? The reason for this could be that one route is more energetically favourable than another, and so a calculation of economy is responsible for certain developmental decisions. Stomata are pores on the surface of the leaf which, in their opening and closing, regulate gas exchange and the movement of water vapour between the interior of the leaf and its environment. Stomatal development is a plastic developmental process which is governed by a series of specific cell division and differentiation events, and therefore provides a suitable model for exploring the relationship between changes in plastic developmental processes and energetic cost to the plant. The work described in this thesis uses a combination of experimental and theoretical methods to further understand the range of cell division, expansion and differentiation events which result in the spacing of stomata within the abaxial epidermis of the model plant Arabidopsis thaliana and the economic costs of those processes, to develop an understanding of the economics of stomatal development.

Abstract:
Guard cells controls the stomata through which exchange of gas takes place by balancing between CO2 uptake for photosynthesis and water loss through transpiration leading to ultimate plant water use efficiency (WUE). Climate change is predicted to lead to greater temperatures and reduced water availability resulting in adverse effect on plant productivity. Sustainable agriculture will therefore require a major reduction in plant water use hence stomata have become potential target for manipulation. Understanding the signal mechanisms of stomata in response to these changing environmental conditions is therefore critically important. In order to facilitate an understanding of stomatal regulation and how it is influenced by the surrounding mesophyll cells, we have used two approaches to find a possible coordination that links mesophyll and guard cell metabolism through the use of stomatal physiology and genetic engineering. The first approach used a novel epidermal mesophyll transfer experiment to monitor stomatal responses to dynamic environmental changes with and without the mesophyll present. The second approach used new molecular tools and techniques to manipulate chloroplast metabolism specifically in the guard cells to elucidate mesophyll-derived signals that coordinate mesophyll CO2 demands with stomatal behaviour towards crop improvement. The results presented have shown guard cells plays a role in stomatal function even though the degree of responsiveness is slower than when the mesophyll is present. Furthermore, the molecular approach demonstrated using Arabidopsis plants overexpressing Rieske and SBPase resulted in substantial and significant impacts on plant development coupled with increases in photosynthetic efficiency of photosystem II in the early stages of seedling development. The result obtained proves more opportunities await the exploitation of guard cells metabolism towards the improvement of plants.
