On the formation of oxalic acid in bleaching.
- 1996
-
Konferensbidrag (refereegranskat)abstract
- In modern pulp mills with prodn. of bleached chem. pulp the increased closure of the bleach plant effluent water system will lead to increased concns. of a variety of dissolved org. substances. Among these oxalic acid is one of the most detrimental due to the facile formation of insol. calcium oxalate once the pH-value is low enough to liberate calcium ions from the pulp. The ppt. may cause severe prodn. problems. Therefore, the formation of oxalic acid from the bleaching of kraft pulps with a variety of bleaching agents have been analyzed. Two methods of anal. have been employed, viz. ion chromatog. and enzymic oxidn. to hydrogen peroxide. The former is a std. method requiring a certain sample treatment whereas the latter may be used on line. Anal. of the aq. phase after each bleaching stage in a O D EO D sequence reveals that oxalic acid can be formed in all stages with the oxygen stage being the predominant contributor. A comparison between different bleaching agents applied to the same pulp again reveals oxygen as a major producer of oxalic acid. The oxalic acid can be formed from both lignin and polysaccharides but expts. with isolated lignin indicates that the predominant part of the oxalic acid is formed from carbohydrates.

Oxalic acid formation during ECF and TCF bleaching of kraft pulp

Konferensbidrag (refereegranskat)abstract
- The formation of oxalic acid (I) during bleaching of softwood kraft pulp was studied. Bleaching agents used were O, H2O2, ClO2, peracetic acid (II), and O3. The formation of I acid increased linearly with the decrease in kappa no. II bleaching gave less I than the other bleaching agents. In O3 bleaching ∼1/3 of the formed I was adsorbed on the pulp and not released until a later stage.

- The aim of this study was to examine possible causes of malnutrition in geriatric patients on admission to hospital by evaluation and comparison of their meal pattern between periods of working, retirement and hospitalization, respectively. Forty-five consecutive patients aged 60 years or older participated. By use of modified dietary history interviews, a retrospective assessment of food intake was carried out. A qualitative system for meal classification was then applied. In the retirement period there was a strong reduction in daily eating frequency when compared to working and hospital periods. Thus, the daily intake and also distribution of energy and nutrients seem to be reduced during retirement, which might lead to nutritional deficiency.

- Recent studies have indicated deteriorated working conditions of health care personnel. To have an efficient health care organization requires good working conditions and the well-being of the personnel. Today there are no 'gold-standard' assessment tools measuring psychosocial working conditions. The aim of this study was to develop two valid and reliable questionnaires, one generic and one specific, measuring psychosocial working conditions for general practitioners (GPs) and district nurses (DNs) in Sweden, with a special emphasis on organizational changes. The construction of the questionnaires were made after a stepwise developing phase including literature review, interviews, and a pilot study. The pilot study included GPs n = 42 and DNs n = 39. The questionnaires were later on used in a main study (GPs n = 465, DNs n = 465). A factor analysis was carried out and showed that there were fewer items in the main study that had factor loading ≥ 0.40 in more than one factor, compared to the pilot study. The factors from the main study were easier to label and had good correspondence with other studies. After this stepwise development phase good construct validity and internal consistency were established for the questionnaire.

Monitoring of dietary quality in outpatients by qualitative meal classification method

Tidskriftsartikel (refereegranskat)abstract
- Background: The aim of this study was to evaluate whether qualitative meal-classification used as a dietary evaluation tool reflects eating frequency and key nutrients in the diet, and whether it could be used to monitor the dietary quality in elderly outpatients. The qualitative meal-classification tool used was based on eight food categories combined into four types of meals: Complete, Incomplete, Less Balanced and Vegetarian Meals, and three types of snacks: High-, Mixed- and Low-Quality Snacks.Methods: Dietary intake was assessed during 7 consecutive days by use of an estimated food record in nine elderly women with leg ulcers. Mean 7-day dietary intakes of energy, macronutrients, beta-carotene, retinol, vitamin E, ascorbic acid, calcium, iron, zinc and dietary fibre were calculated. Each eating event was classified in accordance with the food-based classification method. The frequency of the four types of meals and three types of snacks, their energy content and nutrients, and their contribution to total intake were subsequently analysed.Results: Meals were associated with a higher energy, vitamin and mineral content than were snacks. Complete Meals were the major source for beta-carotene and ascorbic acid. Intakes from Low-Quality Snacks were relatively high in energy, fat and sucrose.Conclusion: The qualitative meal-classification tool was found to be simple to use and useful for reflecting meal order and the nutritional roles of different types of meals and snacks in the diet. This method is recommended for dietary monitoring.

- The aim of the study was to describe the nutritional intake, meal patterns, physical activity and need for help in nine women living in their own homes and being treated for venous leg ulcers. Food habits were identified by use of interviews and food diaries completed by the women during a period of seven days. The intake of energy and nutrients from 304 eating events during seven days was calculated and meal patterns were evaluated using a qualitative system for meal classification. Physical activity and the degree of need were identified with the help of interviews. The intakes of energy and key nutrients for wound healing, such as protein, vitamin C and zinc, were not optimal according to the Swedish nutrition recommendations, although food habits were well organized. Most of the women had hardly any physical activities and the need of help and support varied, from daily visits to visits every second week.
