Abstract

Purpose

Herein, the authors report the effects of printing parameters, joining method, and annealing conditions on the structural performance of fusion-joined short-beam sections produced by additive manufacturing.

Design/methodology/approach

The authors first identified appropriate printing parameters for joining segmented short beams and then used those parameters to print and fusion-join segments with different configurations of stiffeners to form a longer section of a wing or small wind turbine blade structure.

Findings

It was found that the beams with three lateral and three base stiffening ribs give the highest flexural strength among the three beams investigated. Results on joined beams annealed at different conditions showed that annealing at 70 °C for 0.5 h yields higher performance than annealing at the same temperature for longer times. It is also found that in the case of the hot-plate-welded three-dimensional (3D)-printed structures, no annealing is needed for reaching a high strength-to-weight ratio, but annealing is helpful for maximizing the modulus-to-weight ratio. Both thermal buckling and edge wrapping were observed under annealing at 70°C for 0.5 h for 3D-printed beams comprising two lateral and four base stiffening plates.

Originality/value

Fusion-joining of additively manufactured segments is needed owing to the constraint in building volume of a typical commercial 3D-printer. However, study of the effect of process parameters is needed to quantify their effect on mechanical performance. This investigation has therefore identified key printing parameters and annealing conditions for fusion-joining short segments to form larger structures, from multiple 3D-printed sections, such as wind blade structures.

Abstract

Purpose

The objectives of this study were to compare the hygiene standards and food handling practices between sole-proprietor and the corporate-managed restaurants in Lebanon and to determine whether the variations between both groups are explained by and directly related to the type of management.

Design/methodology/approach

An in-depth observation assessment of food safety environment and practices was conducted on a convenient sample of 50 food businesses in Beirut, which are typical of foodservice outlets in Lebanon and in many countries of the Middle East. The observation assessment checklist comprised six constructs of 2–7 components for analysis. It covered all areas including documentation and record-keeping requirements, which are crucial parts of a food safety system.

Findings

There was a significant difference in the visual assessment score between sole-proprietor (77.9 ± 18.4) and corporate group (48.5 ± 12.8). Food handlers' behavior and hygiene standards were significantly associated with the type of management. However, there were still critical gaps in the food safety performance of the corporate group suggesting other underlying factors than the type of management.

Practical implications

Additional elements were drawn from this study for future food safety culture research. Understanding the food safety attitudes and perception of risks of the management representatives, leaders, or food business owners is vital to develop appropriate food safety interventions and foster a positive food safety culture in the foodservice industry.

Originality/value

To the authors’ knowledge, this is the first study not only in Lebanon (or MENA) but also in other regions to measure the association of management type, that is, sole-proprietor management and corporate management, with the food hygiene standards and food safety practices in the foodservice establishments. This paper presents new findings that will be of value for researchers in food safety and will complement the existing literature on food safety culture in the foodservice industry.

Abstract

Sane and civilised people, capable of thinking clearly, now recognise that if the peace of the world is to be secured, and that if another and even greater cataclysm is to be prevented, the Huns and their accomplices must be crushed, and crushed so completely that their recovery of the power to do evil shall be rendered utterly impossible. The persons who are “Pro‐German” for reasons at present best known to themselves, and the peace‐at‐any‐price cranks, may be left out of consideration except in so far as the advisability of placing the former under lock and key and the latter in lunatic asylums demands attention. A premature and inconclusive peace which would make it possible for our abominable enemies to rise again and threaten civilised mankind is unthinkable, and the Allied Powers must of necessity carry on the war until the Thugs of Europe have bitten the dust and have been compelled to sue for peace without terms or conditions. When the “Central Powers” have been forced to their knees, and the Allied armies of occupation have made them taste the bitterness and humiliation of invasion, the surviving criminals will be placed at the bar to receive the sentence of their judges, while the populations who have approved and applauded their hideous acts must also have adequate punishment meted out to them. What form is that punishment to take? The long and ghastly account has got to be read out and settled—so far as it can be settled in this world. What is to be the settlement?

Abstract

The State of Delaware recently passed a new banking law that allows banks and bank affiliates chartered in Delaware to sell and underwrite insurance nationwide. The new laws provide two potential benefits to banks; (1) increased profits from selling insurance and (2) reduced interest rate risk exposure from underwriting insurance. We find support for increased profit potential to banks from the law, but we fail to find a reduction in the interest rate risk exposure of the banks.

Abstract

Since their creation through the Industrial Training Act 1964 to hear appeals against levies, the jurisdiction of industrial tribunals has grown considerably. One aspect of this jurisdiction, unfair dismissal, is examined here. Basic principles related to the law of unfair dismissal are examined. The practice and procedure of an industrial tribunal solely in connection with unfair dismissal cases are examined in greater detail. A case study is used to illustrate the important aspects of procedure. Appendices give relevant forms and extracts from the appropriate Code of Practice.
