Icare ONE handheld rebound tonometry versus goldmann applanation in children with known and suspected glaucoma

Purpose: The Icare ONE (Icare Finland Oy) handheld rebound tonometer, designed for adult home self-tonometry, is a less expensive, computer-linkable version of the original Icare device. No studies have compared Icare ONE to conventional tonometry. The purpose of this study is: 1) to compare Icare ONE tonometry by clinic examiner and parent/guardian to Goldmann applanation tonometry(GAT) in children with known or suspected glaucoma; 2) to use Icare ONE for home tonometry in selected children.

Software project effort assessment

AbstractSoftware project assessments and postmortem analyses can increase the success of future projects and forthcoming project phases. However, although assessments and analyses are well‐presented in the software engineering literature, they are short of descriptions to assess effort. This paper proposes a stepwise effort assessment method that strives to facilitate learning from past experiences and to increase effort estimation accuracy by exploring realized project effort. The proposed method can be used either to assess the realized project effort of a time span from project's lifecycle or as a part of the whole project postmortem analysis in producing effort information for the project iteration assessment, final report, and annual project portfolio report. In addition, the effort information increases the project team's knowledge on realized activity sets and their relationships, and the information can be utilized in estimation method and model calibration for both re‐estimations and future estimations. The method was evaluated with case projects, a sample supplied by Tieto Finland Oy. Copyright© 2010 John Wiley & Sons, Ltd.

UNIQUE LIQUID CARGO HANDLING SIMULATOR IN FINLAND

ABSTRACT Most of the hazardous incidents and accidents in liquid terminals occur during the cargo handling operations, i.e. tanker loading and discharging. The main reason of these incidents is lack of cooperation and communication between the terminal and the ship. Kymenlaakson ammattikorkeakoulu, University of Applied Sciences (UAS) and the Kymenlaakso Region in Southeast Finland aim to improve the operational safety in tanker terminals. One example of this is the Liquid Cargo Handling Simulator located in Kotka in the Seafaring and Logistics Department of Kymenlaakso UAS. The simulator unit consists of two parts, the tanker and the terminal simulator, which are integrated together. In case of oil spill accidents it is possible to train oil combating with the help of PISCESII Oil Spill Management Simulator which is also on part of this unit. The simulator enables the practice of the loading and discharging of different types of tankers and railway wagons. The training aims to teach routine practises as well as safety practises in certain risk situations. It includes also the theoretical part and it is directed at all personnel and students of the field who deal with liquid cargoes in ports. The simulator will be used in the basic studies of Kymenlaakson ammattikorkeakoulu UAS, as part of course activities, and in the training of its personnel and interest groups. The production of the Kymenlaakso University of Applied Sciences’ simulator programme is carried out by Transas from St. Petersburg, a world-leading developer and supplier of Information Technology solutions for the maritime industry. Neste Oil, Port of Porvoo, also contributed to the project. The liquid terminal simulator project is financed by European Union, State Provincial Office of Southern Finland, Kymenlaakson ammattikorkeakoulu, Crystal Pool Ltd, Port of H amina Ltd, Vopak Chemicals Logistics Finland Oy, Neste Oil Oy, Kauko-Telko Oy, SGS Inspection Services Oy, and Baltic Tank Oy.

SU-FF-T-227: Extra-Focal Analytical Source Model for the Radiation Output From a Linear Accelerator

Purpose: To describe in detail the recently improved extra-focal photon source component of an accurate analytical source model for the radiation output from a linear accelerator. Method and Materials: In the Anisotropic Analytical Algorithm used in the Eclipse™ Integrated Treatment Planning System (Varian Medical Systems Inc.) the radiation output from a linear accelerator is modeled using a multiple-source model with separate sub-sources for primary photon radiation, extra-focal photon radiation and electron contamination. Closely related to this, analytical models for accessories such as hard wedges and dynamic wedges are included. We describe in detail the extra-focal photon source component. A recent improvement to the extra-focal source leading to enhanced accuracy in cases of small MLC apertures that are common during IMRT treatments is discussed. Another related improvement significantly improves the modeling of the Varian Enhanced Dynamic Wedge (EDW). Results: The new extra-focal source model significantly improves the modeling of small MLC apertures that occur during dynamic IMRT treatments. In our test case to water phantom the maximum error (disregarding the buildup region) in depth dose curves has been reduced to 1% of dose maximum. Modeling of the Varian Enhanced Dynamic Wedge has been significantly improved also: in our example dataset the worst case deviation of local value at CAX has been reduced by more than 50%. Conclusion: The analytical source and accessory models used in the Anisotropic Analytical Algorithm in combination with a scheme to optimize the free parameters of the model has been already shown to be clinically acceptable. In this work we discuss two improvements related to the extra-focal source model which further improve its accuracy.

The effect of Trichoderma cellulases on the fine structure of a bleached softwood kraft pulp

The mode of action of several Trichoderma reesei cellulase preparations was investigated in relation to their effect on the crystallinity and degree of polymerization of a fully bleached softwood kraft pulp. One complete (Celluclast 1.5L, Novo Industri) and six modified cellulases (Rohm Enzyme Finland Oy, former Primalco Ltd. Biotec) were used under a relatively low enzyme loading of 40 mg protein g −1 cellulose in a reaction mixture in which an excess of exogenous cellobiase activity was added (Novozym 188). This enzyme loading was used to assess the mode of action of the enzymes under both non-saturating and non-inhibitory conditions. The modified cellulase preparations were obtained from T. reesei by deleting the following components of the cellulase system: EG I and/or EG II or CBH I and/or CBH II. Characterization of hydrolysates by gel permeation chromatography (GPC) showed that short incubation times of 4 h with CBH I-deficient enzymes (CBH I− and CBH I/II−mutants) resulted in the highest shifts in the molecular weight distribution of cellulose. Compared to EG-deficient enzymes (EG I−, EG II− and EG I/II−mutants), the lack of CBH II resulted in equivalent changes in both polydispersities and average degrees of polymerisation of cellulose. This suggested that the role of CBH II in hydrolysis was similar to that of both endoglucanases I and II. The effectiveness of all mutant enzymes in hydrolysing cellulose was much lower than that obtained when a complete cellulase system such as Celluclast 1.5L was used. Our results also indicated that the lack of CBH I was very detrimental to hydrolysis and depolymerization of cellulose and that EG I has a greater effect on the substrate than EG II. However, there were no detectable changes in the degree of crystallinity of partially hydrolysed pulps, regardless of the enzyme system used.

Updraft gasification of peat and biomass

The Technical Research Centre of Finland and Bioneer Oy have developed the Bioneer updraft fixed-bed gasifier for peat and biomass. The use of low-Btu gas has reached a commercial level, and there are ten operative gasifiers in Finland and Sweden. The thermal output of these unitsranges 2–6 MW. Recent development work has focused on gasifying low-grade fuels, such as different wood wastes and straw, and on purification of tars from the gas.
