Thermal and sound insulation performance assessment of vacuum insulated composite insulation panels for building façades

Composite insulation panels (CIPs) currently used in building façades require significant design changes e.g. increased thickness to realise higher thermal and sound insulation performance. This study deals with the manufacturing and characterisation of smart façade panels for achieving higher thermal and sound insulation dual characteristics in one panel without a significant increase in thickness. Prototype panels were manufactured using vacuum insulation core (VIC) combined with mass loaded vinyl (MLV) layers. Thermal transmission and weighted sound reduction index (R_w) was experimentally measured in the laboratory. The results were compared with a control panel made with extruded polystyrene (XPS) core. The VIC panel showed a 51% improvement in the centre of panel U-value compared to control XPS core panel of the same thickness. Integrating the two MLV layers inside of aluminium skins either side of the vacuum insulation panel led to 3dB improvement in R_w from 32 dB to 35 dB which could be further improved by optimising the MLV layer positioning in the CIP and better bonding between the MLV and the vacuum insulation panel. This shows that vacuum insulation core panels combined with MLV offers a solution to achieve smart building façade with excellent thermal and sound insulation performance

Interpretation and parameterization of dynamic trunk isoinertial movements using an ensemble-averaging technique.

A procedure for averaging trunk dynamometric positions, velocities, and torques is described which enables identification and parameterization of kinematic movement patterns. This technique is accurate and presents the data in a very compact way, which is ideal for storage and analysis. It can be applied to many types of movement analyses. Application of the technique to the analysis of flexion-extension movement patterns in two low back pain patients is described.Journal Articleinfo:eu-repo/semantics/publishe

Familial trisomy 11p resulting from a balanced paternal translocation: 3 new cases including first trimester diagnosis.

Three related new cases with almost complete trisomy 11p due to paternal balanced translocation 46, XY, t(7; 11) (q36.1; p11.1) are reported. The proband (Case 1) was a malformed stillborn with exomphalos, case 2 was diagnosed in the first trimester by direct chromosome preparations from chorionic villi, and confirmed on fetal products after termination of pregnancy. Case 3, a cousin to cases 1 and 2, was a 29-weeks-old fetus with omphalocele discovered at ultrasound. Literature reports of trisomy 11p are reviewed with regard to those new cases, and the possible relationship of this chromosome imbalance with the Beckwith-Wiedemann Syndrome is discussed.Case ReportsJournal Articleinfo:eu-repo/semantics/publishe

Antenatal diagnosis of congenital diseases through cultured amniotic cells :results of 149 amniocenteses

After discussing the main technical problems related to prenatal diagnosis the authors report on their results with 149 amniotic cell cultures. In 5 of them examination was requested for a suspected inborn error of metabolism. In 6 cases a risk of a severe X linked familial disease led to antenatal sex determination. In the great majority of the cases foetal caryotype was required. Four cases of trisomy 21 and one case of trisomy 13 were detected. All prenatal diagnoses could be confirmed in the foetus or the newborn.info:eu-repo/semantics/publishe
