The purpose of this paper is to study thickness dependent variation in microwave properties of the Mg_xMn_(0.9−x)Al_0.1Zn_0.8Fe_1.2O₄ (x=0.8, 0.9) thick films and enhancement of power efficiency of Ag thick film EMC patch antenna.

X‐band microwave properties of the Mg_xMn_(0.9−x)Al_0.1Zn_0.8Fe_1.2O₄ (x=0.8, 0.9) thick films were measured by superstrate technique using Ag thick film EMC patch antenna as the resonant element. The complex permittivity and permeability of these thick films were also measured by this technique. The microwave response of the EMC patch, complex permeability and permittivity of Mg_0.8Mn_0.1Al_0.1Zn_0.8Fe_1.2O₄ and Mg_0.9Al_0.1Zn_0.8Fe_1.2O₄ thick films and their thickness dependency were investigated.

The XRD patterns reveal the cubic spinel crystal system was obtained for both compositions. The crystallite size obtained was 134.68 nm for Mg_0.8Mn_0.1Al_0.1Zn_0.8Fe_1.2O₄ and 155.99 nm for Mg_0.9Al_0.1Zn_0.8Fe_1.2O₄ The superstrate technique has been used successfully to evaluate the complex permittivity and permeability of the ferrite thick films in the X band. The EMC patch also show thickness and composition dependent frequency agility and enhancement of power efficiency.

The complex permeability of Mg_xMn_(0.9−x)Al_0.1Zn_0.8Fe_1.2O₄ (x=0.8, 0.9) thick films measured by superstrate technique is reported in this paper. The superstrate of Mg_xMn_(0.9−x)Al_0.1Zn_0.8Fe_1.2O₄ (x=0.8, 0.9) thick films makes the Ag thick film EMC patch antenna frequency agile and power amplification is obtained.

THE major problems connected with the development of satisfactory structural strength requirements have long since been solved. We have, in this country, an empirical system of specification which fulfils the fundamental criterion of any strength system, namely, that failures in the air through lack of adequate strength of any component of an aircraft are extremely rare. An analysis of civil accidents (Ref. 1) shows that about 6 per cent are due to this cause. This does not imply any reason for regarding even this small number with complacency, rather the reverse.

Despite significant investments in efforts to broaden participation, the number of women in science, technology, engineering, and mathematics (STEM) fields who leave the academy is disheartening. Some reports suggest half of women STEM faculty will leave tenure track positions within 10 years after hire (Kaminski & Geisler, 2012). For women of color, the data are equally bleak (Ginther & Kahn, 2012) and affirm the need for continuously evolving practices and policies to retain underrepresented faculty in STEM and ensure career satisfaction and success. Unfortunately, current programs for career development and mentoring largely promote rigid conformity to traditional performance expectations, which enable the persistence of narrow departmental norms regarding markers of success. By drawing on person–environment (PE) fit theory, and combining data from our own institution with evidence-based practices from others, the authors have created a faculty development program designed to upend this practice. The objective of this program is to help faculty advance their careers in the academy while staying true to what they value, while simultaneously helping departments reflect on how they can create more inclusive and supportive environments for all faculty. The authors describe the program in detail and provide initial assessments of impact on faculty participants as well as departmental and institutional practice.

This paper summarises three empirical studies investigating staff attitudes towards client sexuality, with special consideration of issues surrounding HIV infection. A questionnaire survey design was employed, with 585 participants completing three separate questionnaires. Between 1990 and 1998 staff attitudes towards client sexuality became more positive, with a significant reduction in the number of staff agreeing with mandatory HIV testing over the three studies. In the final study, a significant number of staff Reported being unaware of, or uninfluenced by, organisational sexuality policy. The interaction between policy, staff beliefs and practice is discussed. When staff are aware of the policies on sexuality, their beliefs and attitudes appear to filter these policies, with staff behaviour influenced by an interaction between policies and beliefs. In conclusion, policy development needs to involve inter‐agency collaboration, as well as staff and client user input, for best practice in sexuality.

The factors which influence costs of production of food and the prices to the consumer have changed dramatically during this century, but especially since the establishment of trading systems all over the world. Gone are the days when the simple expedients of supply and demand alone governed the situation. The erosion of these principles began at the turn of the century, mainly as a result of the introduction by the rapidly developing industrial power of the USA to protect her own industries against the cheaper products of European countries. They introduced the system of tariffs on imported manufactured goods; it grew and eventually was made to apply to wide sectors of industry. European countries retaliated but the free trade policy of Britain's Liberal government was making the country a dumping ground for all other country's cheap products and surpluses.

Identified risk factors and clinical experience suggest that self‐harm is a common and very significant problem in forensic psychiatric settings. Sparse training on self‐harm given to staff throughout professional development is a concern for staff who can be left feeling dissatisfied and powerless as how to manage the patient who self‐harms. Consequently, staff often have to rely on idiosyncratic beliefs about self‐harm and its management to guide their practice. This survey investigated staff attitudes towards self‐harm in a forensic psychiatric service. The results highlight much variation in attitudes and a sub‐population of staff holding relatively more punitive/negative beliefs. In addition, the survey drew attention to the difficulty of managing self‐harm in forensic settings‐especially in relation to issues around facilitating safe self‐harm.

This register of current research in social economics has been compiled by the International Institute of Social Economics. The register does not claim to be comprehensive but is merely an aid for research workers and institutions interested in social economics. The register will be updated and made more comprehensive in the future but this is largely dependent on the inflow of information from researchers in social economics. In order to facilitate this process a standardised form is to be found on the last page of this register. Completed forms, with attached sheets as necessary, should be returned to the compiler: Dr Barrie O. Pettman, Director, International Institute of Social Economics, Enholmes Hall, Patrington, Hull, N. Humberside, England, HU12 OPR. Any other comments on the register will also be welcome.

The purpose of this paper is to report the effect of bismuth oxide thick films of various thicknesses on the X band (8‐12 GHz) response of Ag thick film microstrip rectangular patch antenna.

The effect of bismuth oxide thick film overlay of different thickness on Ag thick film microstrip rectangular patch antenna was investigated in the X band (8‐12 GHz). The change in the resonance frequency, amplitude, band width, quality factor, and input impedance of the antenna were studied. Using the resonance frequency the permittivity and conductivity of bismuth oxide thick film was measured.

Thickness of Bi₂O₃ thick film overlay dependent changes in the patch antenna characteristics is obtained. The resonance frequency shifts to higher frequency end due to overlay. The input impedance decreases due to the overlay. The dielectric constant of bismuth oxide thick film calculated from shift in resonance frequency shows thickness dependent values.

The microwave permittivity and conductivity of Bi₂O₃ thick film have been reported for the first time using overlay on thick film patch antenna. Thickness of overlay dependent tuning of the antenna has been achieved.

The purpose of this paper is to compare thick and thin film microstripline response to conducting overlay.

Study changes in transmission and reflection of both thick and thin film microstripline due to overlay of polyaniline (PANI) thin film on stainless steel and silver. PANI was deposited by electropolymerisation method using HCl and H₂SO₄.

Transmittance of both the thick and thin film microstripline decreases due to the PANI overlay and reflectance increases. Thin film microstripline is more sensitive to the type of conducting overlay than thick film microstripline. PANI deposited on silver is more absorbing than PANI deposited on stainless steel using HCl acid. The overlay makes the response of the microstripline more dispersive.

The increase in reflectance and decrease in transmittance can provide information about the type of overlay materials. There is need for newer materials which can replace traditional metals for microstrip components. PANI might serve this purpose.
