The main aim of this study was to improve current efficiency and to obtain thicker coatings via aluminum oxide (Al₂O₃) addition to the chromium (Cr) (III) bath.

Pure Cr and nanocomposite Cr–Al₂O₃ coatings were electrodeposited from Cr (III) bath onto cathode copper substrates by conventional method. Dependence of current efficiency to current density, Al₂O₃ content and particle size were investigated.

Current efficiency increased with Al₂O₃ amount and decreased with Al₂O₃ particle size. Maximum current efficiency was achieved at 25 A/dm₂ for pure Cr and 30 A/dm₂ for composite coatings. Al₂O₃ bath content, current density and stirring rate increased the coating Al₂O₃ weight per cent significantly. Addition of Al3+ bath composition inhibited nanoparticle agglomeration, increasing film homogeneity. Cr–Al₂O₃ nanocomposites showed higher microhardness and better corrosion resistance than pure Cr layer.

Cr (III) is not as toxic and as carcinogenic as Cr (VI) which is widely used for Cr electroplating these days. Low current efficiency and poor product quality are, however, major drawbacks of the former. This paper describes significant improvements obtainable by addition of Al₂O₃ nanoparticles to the Cr (III) bath for increasing the microhardness, the corrosion resistance and the current efficiency of the deposition.

The nature and purpose of the catalogue has been the focus of considerable and vigorous debate during the past decade. This article attempts to identify those topics which have been the most significant causes of the debate and discusses: the need for catalogues; users and non‐users; the nature of the bibliographic record and catalogue entry; the development of UK and LC MARC; standards, including exchange formats, the development of the ISBD, and the concept of UBC (Universal Bibliographic Control); the Anglo‐American Cataloguing Rules and the controversy over the implementation of AACR2; COM catalogues; subsets of the MARC record; co‐operatives, networks and resource sharing; and the development of subject access methods better suited to COM and online catalogues. The relevance of catalogue research activities at Bath University and elsewhere is highlighted.

This paper aims to develop a simple and efficient shell element for large strains hyper‐elastic analyses.

Based on the classical MITC4 shell element formulation a 3D shell element with finite strain kinematics is developed. The new quadrilateral shell element has five dof per node and two global dof to model the thickness stretching. The shell element is implemented for hyperelastic material models and the application of different hyperelastic constitutive relations is discussed.

The results obtained considering three of the hyperelastic material models available in the literature are quite different when the developed strains are relatively high; this indicates that, for analyzing actual engineering examples, experimental data should be used to decide on the most suitable constitutive relation.

The 3D version of the MITC4 element was developed.

The purpose of this study is simultaneous dyeing and mordanting of wool yarns with extracted cochineal dye and aluminum sulfate to the reduction of consuming energy, water and time.

The dyeing process was optimized using the response surface methodology (RSM) approach. pH, dyeing duration and the presence of additives were chosen as variables and the color strength of samples as a response. The color characteristics and fastness attributes of samples dyed in the best condition were evaluated and compared to pre-mordant dyeing outcomes on wool yarns.

The best conditions for deep dyeing wool with cochineal dye were as follows: pH 2.5, time 110 min and the ratio of aluminum: additives 1:0 at 100 °C. Color strength of dyed wool yarns by one-bath and pre-mordant dyeing methods were approximately the same. Wool yarns can dye to the on-bath dyeing method such that the dyed samples have similar color strength and fastness properties to pre-mordant dyeing.

Wool dyeing processes that use one-bath dyeing consume less water and produce fewer effluents. As a result, this strategy conserves water and energy for a higher quality of life. The findings of this study, in general, aid environmental protection.

A novel one-bath process for dyeing wool with cochineal dye at heavy depths is introduced. RSM was used to optimize the procedure and determine effective parameters on the color strength of dyed wools. Using extracted cochineal dye and aluminum sulfate in a simultaneous dyeing technique, good color fastness qualities on wool fibers were achieved.

The corrosion of Zn in both aerated by air (O₂ + N₂), and deaerated by N₂, solutions of KNO₃ at concentrations largely varying, 10^‐5‐1 M, is studied. The corrosion process is followed in time by potentiometry and the potential of Zn electrode (vs. calomel) vs. time plots is derived. In both cases, a transition period is observed until a steady state is achieved where the rate of Zn²⁺ and OH^‐ production becomes equal to the rate of Zn(OH)₂ precipitate formation. In the aerated solutions the potential and corrosion rate decrease with time while in the deaerated solutions they pass successively through a minimum and a maximum before a steady state is achieved. By a suitable potentiometric analysis the results are explained. The most important factors found to be affecting the mechanism of corrosion process are presented. From the discovery of the mechanism and the factors affecting the Zn corrosion, predictions for promoting or slowing down the corrosion process may be derived.

ON MAY 1ST, 1766, diligent newspaper readers, perusing the front pages of their favourite journals over breakfast, noticed a brief announcement amongst the plethora of advertisements for miracle cures and infallible nostrums. It read: ‘This day is published: elegantly printed on fine medium writing‐paper, in quarto, price five shilings, The New Bath Guide: or Memoirs of the B—n—r—d family. In a series of poetical epistles … Sold by J. Dodsley in Pall Mall’.

THE Librarian faces one of the turning times in library history. The flow of progress has not yet begun, the shortages and consequent imperious demands for food, housing and clothing stand in the way of the beginning, except on paper. How long the interregnum will last none can say. The authorities, which are a reflection in some ways of the Parliamentary party in power, are well‐disposed towards libraries; the official handbook of the Labour Party proves that; but the clamour of the needs we have mentioned deafens everybody to library needs—except in certain instances. For example, the rebuilding and enlarging of the staff at Holborn is an encouraging sign. Of more potential significance is the working out of the so‐called National Charter. It has involved many towns in the task of creating an establishment for each public department. Thus, in one library system we hear that each branch or department may claim a librarian and a deputy both on the A.P.T. scale, but all the assistants are either general or clerical. Some assistants we hear have applied to be of clerical grade as the maximum salary is greater than in the general. This we suggest is putting cash before status because it is accepted as an axiom that a clerk has only clerical qualifications and potentialities, while a general assistant may aspire, when there is a vacancy and if he have certificates, to the professional status. The grading in the particular library mentioned has rather a petrifying effect in that no assistant can get into the professional grade unless his librarian or deputy departs. Possibly this sort of thing may alter, but the fact remains for good or ill—it is not all ill by any means—that no library is able to attract men from another except to a definitely higher post.

This work aims to increase the dyeability of nylon 6 with basic dyeing through the treatment of the fibre with available and cheap nanomaterials, namely; nano bentonite using an economic and simple method.

Different amounts of nano clay, namely, nano bentonite were dispersed in distilled water using an ultrasonic homogenizer for 1 h. Nylon fabrics were treated with different concentrations of dispersed nano bentonite (1%, 2%, 3%, 4%, 5% wt/v). After half an hour, the samples were padded using SVETEMA laboratory padding system. The padding pressure was adjusted at 3 bar to allow a pickup of 100%. The padded samples were dried at 80°C for 5 min and cured at 160°C for 3 min using ROACHES laboratory thermos-fixation. The cured samples were then washed with running water and left to dry at room temperature.

The obtained results indicated that the modification of polyamide 6 fibres with nano bentonite had a great impact on their dyeing properties. The obtained shades, absorption behaviour and fastness properties were significantly enhanced. Based on these results, it was concluded that polyamide fabrics could be successfully dyed with basic dyes using economical dyeing conditions.

This paper introduces a new method the loaded the nano-clay on the synthetic fibres, which are nylon 6 to enhance the dyeability with cationic dyes using the physical method without changing the structure of the fibres.

A number of approaches have been developed in recent years to try effectively to engage service users in the process of planning and delivering health‐care services. The consumerist methodology for the strategy described in this paper was designed to maximise staff involvement in capturing user views, in order to develop services at a district general hospital. This strategy – the Patient Care Development Programme (PCDP) – provides a framework for both staff and patient involvement in shaping and influencing the development of health‐care services. Uses the findings from applying the strategy to modify care packages, roles, skills, layouts, protocols and procedures, in response to both the “shortfalls” and the service strengths that the patient’s view uncovers. Discusses the results of an evaluation of the programme which has been replicated in another part of the UK. The PCDP now forms part of a clinical governance framework and is being used to develop multi‐agency integrated care pathways.

EVERY librarian in his inmost heart dislikes newspapers. He regards them as bad literature; attractors of undesirable readers; a drain upon the limited resources of the library; and a target against which the detractors of public libraries are constantly battering. From the standpoint of the librarian, newspapers are the most expensive and least productive articles stocked by a library, and their lavish provision is, perhaps, the most costly method of purchasing waste‐paper ever devised. Pressure of circumstances and local conditions combine, however, to muzzle the average librarian, and the consequence is that a perfectly honest and outspoken discussion of the newspaper question is very rarely seen. In these circumstances, an attempt to marshal the arguments for and against the newspaper, together with some account of a successful practical experiment at limitation, may prove interesting to readers of this magazine.
