1. 31. INVESTIGATING THE TOXIC AND ACIDIFYING EFFECT OF SCRUBBER EFFLUENT ON STRONGYLOCENTROTUS DROEBACHIENSIS LARVAE

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Ida Vartia; [2022-09-28]
   Keywords : ;

   Abstract : To meet the new environmental requirements of reduced sulfur emissions from ships, many shipowners have installed an open-loop scrubber to clean the exhaust. In this scrubbing process, seawater is pumped from the ocean and combined with the emission gas, creating an acidic and toxic effluent that is directly discharged into the ocean, potentially damaging the marine environment.

3. 32. Fluctuating pH simulating natural variability modulates larval growth for Strongylocentrotus droebachiensis

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Bryn Anderson; [2022-08-05]
   Keywords : ocean acidification; global change; sea urchin; duration; intensity; biological response;

   Abstract : Ocean acidification (OA) is the downward trend of ocean pH mainly resulting from the absorption of carbon dioxide (CO2) emissions from anthropogenic sources. pH of the open ocean is expected to drop to 7.7 by the end of the century. READ MORE

4. 33. Impact of storage at freezing temperatures on casein micelle size, coagulation properties and curd yield in bovine milk

   University essay from SLU/Department of Molecular Sciences

   Author : Ebba Bondesson; [2022]
   Keywords : Casein micelle size; milk coagulation time; gel strength; curd yield; freezing; freeze drying;

   Abstract : Frozen storage is an efficient and convenient way to preserve and transport milk, but the effect from frozen storage needs to be further researched. The objective of this study was to investigate how storage at freezing temperatures (-80°C and -20°C) of frozen and freeze-dried bovine milk samples, respectively, affects pH, casein micelle size, ethanol stability, rheological properties and curd yield.

5. 34. Study of yield variation in a pharmaceutical manufacturing process and optimization of purification subsection : By a design of experiments study of the production parameters and a laboratory study of the purification step

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Sandra Lord; [2022]
   Keywords : Yield variations; activated carbon; pharmaceutical industry; purification; design of experiments; optimization; Utbytesvariation; aktivt kol; läkemedelsindustrin; reningssteg; experimentell design; optimering;

   Abstract : The product R1-MR2E is an ester formed from an esterification of a carboxylic acid and an alcohol at Cambrex Karlskoga AB. The production of the intermediate R1-MR2E is a large-scale production and there are two main objectives and two sub-objectives that this project aims to study of the manufacturing. READ MORE

6. 35. Coacervates as a subcutaneous drug delivery system

   University essay from Uppsala universitet/Institutionen för läkemedelskemi

   Author : Dania Elkhalifa; [2022]
   Keywords : ;

   Abstract : Subcutaneous administration of biological drugs has become highly attractive as it offers the possibility for patient self-administration. Coacervates as a subcutaneous drug delivery system provide a way to decrease injection volumes thereby reducing the risk of injection site pain. READ MORE
