The CSTI Document Delivery Service (DDS) of the South African Council for Scientific and Industrial Research (CSIR) was compelled to examine alternative systems for request handling, record keeping and invoicing when its manual system could no longer cope with the ever increasing volume of requests. A fully computerised system on microcomputer was chosen and developed by a senior programmer in the Institute. It is now possible for a relatively small staff to handle the large and increasing volume of requests routinely and with ease. The system is also used for in‐house invoicing, accounts queries, credit control and automatic generation of statistics for record keeping and forward planning. This system has proved to be very flexible and it has led to a number of initially unforeseen advantages. One such advantage is electronic request transmission to the British Library Lending Division (BLLD) on its Automatic Request Transmission (ARTTel) system. Another is the possibility of using a similar system for the transmission of requests to the CSIR's Scientific Liaison Offices overseas. The link to the CSIR computer network also presents the possibility of using the DDS microcomputer as a terminal on the mainframe for archival purposes and for accessing the electronic mail service.

Discusses why interlibrary loan (ILL) has not been the subject of substantial automation and briefly discusses the current state of ILL automation in the UK. Suggests that the Library and Information Co‐operation Council (LINC) is uniquely placed to monitor developments. Recommends further action for LINC including its role in collection and dissemination of information and influencing developments in ILL automation.

This study employs the social ecology model to comprehensively explore the complex challenges young Black men face in South Africa and aims to highlight the importance of collaboration in addressing these multifaceted issues.

A multidisciplinary approach combines insights from sociology, education and the health literature with regard to government reports and academic data, and provides a holistic analysis of challenges faced by young Black men. Furthermore, it emphasises formal and informal learning, social and environmental influences and health disparities.

Young Black men in South Africa encounter complex challenges throughout their developmental journey, including limited family support, educational barriers, financial constraints, societal expectations and health disparities. Therefore, collaboration among stakeholders is essential for creating an equitable and inclusive environment that supports their development.

This research provides a comprehensive understanding of the challenges faced by young Black men in South Africa by emphasising the interconnectedness of informal education, economic empowerment and healthcare. Future research should focus on longitudinal studies, cultural influences and international comparisons, informing evidence-based interventions for a more equitable society.

Media power plays a role in determining which news is told, who is listened to and how subject matter is treated, resulting in some stories being reported in depth while others remain cursory and opaque. This chapter examines how domestic violence and abuse (DVA) is reported in mainstream and social media encompassing newspapers, television and digital platforms. In the United Kingdom, newspapers have freedom to convey particular views on subjects such as DVA as, unlike radio and television broadcasting, they are not required to be impartial (Reeves, 2015).

The gendered way DVA is represented in the UK media has been a long-standing concern. Previous research into newspaper representations of DVA, including our own (Lloyd & Ramon, 2017), found evidence of victim blaming and sexualising violence against women. This current study assesses whether there is continuity with earlier research regarding how victims of DVA, predominantly women, are portrayed as provoking their own abuse and, in cases of femicide, their characters denigrated by some in the media with impunity (Soothill & Walby, 1991). The chapter examines how certain narratives on DVA are constructed and privileged in sections of the media while others are marginalised or silenced. With the rise in digital media, the chapter analyses the changing patterns of news media consumption in the UK and how social media users are responding to DVA cases reported in the news. Through discourse analysis of language and images, the potential messages projected to media consumers are considered, together with consumer dialogue and interaction articulated via online and social media platforms.

Aluminum tripolyphosphate was used as a corrosion inhibitor in a simulated concrete pore solution. For studies of the inhibition mechanism of aluminum tripolyphosphate on the carbon steel, its influence on the pitting initiation on the carbon steel in a Cl⁻ containing pore solution were investigated.

Potentiodynamic polarization curves, Mott–Schottky plots and potentiostatic polarization of the carbon steel in the pore solution with different content of aluminum tripolyphosphate were measured, as well as the optical micrographs of pitting on the carbon steel was observed.

The metastable pitting potential and the stable pitting potential increased, while the donor density and the flat band potential decreased with the concentration of aluminum tripolyphosphate in solution. Furthermore, the initiation of pitting was suppressed, as well as the transition from metastable to stable pitting was hindered by the aluminum tripolyphosphate. The scale parameter (a), in the extreme distribution of the maximum current peak, could be used to predict the transition from metastable to stable pitting.

The inhibition mechanism of aluminum tripolyphosphate on carbon steel in pore solution was revealed. It suppresses the initiation of pitting and hinders the transition from metastable to stable pitting. Furthermore, a parameter defined as the scale parameter (a) in the extreme distribution of the maximum current peak was introduced to predict the transition from metastable to stable pitting.

Clinical professionals working with psychologically traumatised children in the care system can experience potential challenges maintaining their own positive psychological health, and when repeatedly being exposed to the traumatic histories of those in their care. The purpose of this paper is to increase the understanding of vicarious trauma and provide a guide for focussing on future research.

This is a systematic literature review, considering 13 articles that met the criteria and identified five main themes linked to secondary traumatic stress/vicarious trauma in staff.

Five main themes were noted. These are: lack of organisational support; lack of health work-life balance; lack of appropriate training; failure to use self-care techniques; and staff failure to share when they are experiencing symptoms.

Various implications are noted from this review. These include: the importance of education and support for staff, to be mindful that newer staff may be considered an “at risk” group for the negative impact of such trauma, and to encourage staff in achieving an effective work-life balance.

This is a focussed systematic review on secondary and vicarious trauma on staff working with children exposed to psychological trauma, such as sexual and physical abuse.

Low nickel austenitic stainless steel (ASS) has attracted much attention worldwide because of its economical price. This study aims to investigate the effect of different corrosive environments on the corrosion behavior of chrome-manganese (Cr-Mn) ASS. The tests were carried out as a function of H₂SO₄ concentrations, temperature and addition of ammonium thiocyanate (NH₄SCN) (0.01 M). Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques were used to study the corrosion behavior of Cr-Mn ASS. It was observed that with increasing H₂SO₄ concentration, temperature and with the addition of NH₄SCN solution, icorr, icrit and ipassive values increased. EIS data show decreasing charge transfer resistance value with increasing concentration and temperature. Higher corrosion rate with increasing temperature and concentration of H₂SO₄ is related to the anions (SO₄²⁻), which is responsible for reducing the stability of passive films. With the presence of 0.01 M NH₄SCN thiocyanate (SCN⁻ anion), there is a higher dilution of the passive film resulting in a higher corrosion rate. Energy-dispersive spectroscopy (EDS) analysis reveals the adsorption of sulfur on the surface in NH₄SCN containing a solution. The significant presence of counter ions and the adsorbed sulfur species on the steel surface play a vital role in corrosion behavior.

All the experiments were performed on a 3 mm thick sheet of Cr-Mn ASS (202 ASS) in hot rolled condition. The samples were then annealed at 1,050°C for 1 h, followed by water quenching. For microstructural examination, they were electrochemically etched in 10 Wt.% oxalic acid solution at 1 amp for 90 s. A computer-controlled Potentiostat (Biologic VMP-300) was used. After the cell was set up, the working electrode (WE) was electrostatically cleaned at −1 V vs saturated calomel electrode (SCE) for 30 s to remove the air-formed film. Then, WE were allowed to attain stable open circuit potential (OCP) for 1 h, following by the EIS test and potentiodynamic polarization test. The polarization test was started from a cathodic potential (−1.2 V vs SCE) and continued up to an anodic potential (1.6 V vs SCE) a scan rate of 0.1667 mV/s. EIS experiment was conducted on the same instrument by using a sinusoidal AC signal of 10 mV in a frequency range of 1,000,000 to 0.01 Hz at OCP.

Potentiodynamic polarization graph shows that with the increase in sulphuric acid concentration. Increasing temperature from 20°C to 80°C in 0.5 M H₂SO₄ solution increases the corrosion rate (icorr) of Cr-Mn ASS. On the addition of 0.01 M NH₄SCN to the sulfuric acid solution (0.1, 0.5 and 1 M) the corrosion rate increases drastically almost four to five times. EDS and XRD analysis shows the presence of sulfur over the oxide film and preferential site for dissolution of Cr and Mn at the steel surface when NH₄SCN is added to the sulfuric acid solution.

A study on the corrosion behavior of Cr-Mn ASS is scanty according to the author’s knowledge. Therefore, the present study will investigate the corrosion behavior of Cr-Mn ASS on SO₄⁻² anions, temperature and the addition of SCN⁻ ion in sulfuric acid.

The purpose of this paper is to quantitatively assess the pit growth rate on AISI 304L and AISI 316 austenitic stainless steels in natural seawater and 3.5 wt.% NaCl solutions through electrochemical measurements during the potentiostatic growth of pits.

A quantitative characterisation was carried out based on chronoamperometric measurements. The volume of dissolved metal per pit was calculated from the charge registered and Faraday's law, considering both, hemispherical and semi‐elliptical pit shapes and the density of the steels. Empirical growth laws for maximum pit depth as a function of polarisation time were obtained and compared with pits volumetric profile obtained from optical microscopy analysis and mechanical removal of material on both steels.

Electrochemical‐based calculations of localised metal dissolution per pit present acceptable fit with the real volume of dissolved metal on hemispherical pits.

The paper presents the quantitative relationship of the corrosion pit growth rate of stainless steels in chloride containing solution determined by chronoamperometry (electrochemical technique) through the Faraday law's, with the mechanical removal of material (pit profile) through the density of metal.
