Real-time process monitoring of Spark-Assisted Chemical Engraving (SACE) machine with data-driven techniques
Spark-Assisted Chemical Engraving (SACE) is a promising technique for glass microfabrication, offering good surface quality and machining speed. However, inherent uncertainties arising from gas film instability and the stochastic nature of the process lead to inconsistencies and reduced …

The role of N-linked glycosylation on the structure and function of somatic angiotensin-converting enzyme
… and function of the full-length somatic ACE (sACE) has remained elusive. A novel MG-sACE mutant, comprised of previously characterized MG N- and C-domains was generated. Unfortunately, the protein was susceptible to limited proteolysis in the interdomain linker region, suggesting that key …

Discourses of professionalism and the production of teachers' professional identity in the South African Council for Educators (SACE) Act of 2000 : a discourse analysis
… in the South African Council for Educators (SACE) Act of 2000. These identifies are located in the context of their social impact on, and in the actualisalion of the political roles of teachers in post-apartheid South Africa. Central to the study is the conceptualisation that discourses …

Investigation of signal shape effects on the gas film in spark-assisted chemical engraving
Spark-Assisted Chemical Engraving (SACE) is a promising method for machining glass micro-parts and devices. However, intricate control requirements linked to the gas film surrounding the tool present a significant challenge in SACE. While several studies have explored the influence of SACE …

Investigating the effects of AC voltage signals on micro-channels machined with the Spark Assisted Chemical Engraving process
Spark-Assisted Chemical Engraving (SACE) is a non-conventional method for microfabrication in glass. The process relies on multiple parameters for machining, but its stochastic nature often reduces the predictability of machining outcomes. While prior work has studied various individual parameters, …

Mechanisms of chloride modulated activity in the C-domain of angiotensin-converting enzyme
… isoform of angiotensin-converting enzyme (sACE), a key regulator of blood pressure and electrolyte fluid homeostasis, primarily cleaves the hypertension-associated angiotensin-I (AngI) and bradykinin peptides, as well as a number of other physiologically relevant peptides in vitro. sACE …

A Molecular Basis for the C-Domain Selectivity of Angiotensin-Converting Enzyme
… disease. Two isoforms exist,somatic ACE (sACE) consisting of two homologous domains, N- and C-domain, and testisACE (tACE), corresponding to the C-domain of sACE. Despite a high degree of sequenceidentity, these two domains display marked differences in substrate and inhibitor …

The design and development of a Spark Assisted Chemical Engraving system with force feedback control
… system for precision manufacturing using SACE technology. The setup consists of a machining head and a processing cell. The electronics of the system are implemented on printed circuit boards and embodied in a well-ventilated box that connects the different components of the system. A …

Angiotensin-converting enzyme cleavage of the Alzheimer's beta-amyloid peptide
… In contrast to Aβ(1-16) and Aβ(410)Q, both sACE and the double C-domain (CC-sACE) construct showed positive domain cooperativity towards Aβ(4-10)Y. The high-resolution crystal structures of the N-domain in complex with five Aβ peptide fragments provided an overlapping, conserved, molecular …

Murder Scenes: Criminal Violence in the Public Culture and Private Lives of Weimar Berlin
"This dissertation is a study of criminal violence and urban culture in Berlin during the Weimar period. Based on police and court documents and newspaper accounts, it examines how Berliners experienced and made sense of homicidal violence within their urban communities. Criminal violence occupied …

A study of factors contributing to underachievement in exponential and logarithmic functions in the Further Education and Training school phase
… with the South African Council for Educators (SACE), their performance on the same test taken by their learners was only marginally above the performance of their learners. The educators’ responses to the question about their readiness to teach exponential equations and logarithmic functions …

Development of N-domain selective Angiotensin-I Converting Enzyme (ACE) inhibitors using Computer Aided Drug Discovery (CADD)
… the regulation of blood pressure. Somatic ACE (sACE) consists of two structurally homologous yet distinct catalytic sites termed the N- and C-domains. The two catalytic domains of ACE have distinct substrate affinities and play different regulatory roles. The antifibrotic tetrapeptide Ac-SDKP is …
