Information serves as an essential intermediate input in decision-making for any business process. It is an essential requirement not only for effective and efficient management but also for medium and long term planning. In this era of technological advancement the rapid growth of information flow has contributed significantly in the expansion of business, commercial, industrial, financial, educational and research organisations. Electronic communication provides the ability to overcome many organisational problems. In recent years, an easy and inexpensive access to information through the Internet and e-mail has created an atmosphere of strong competition among organisations. In this competitive environment, the organisations need an efficient, productive and competent internal set-up based on a well-informed workforce. In the absence of effective co-ordination, the expansion of an organisation may result in inter-group conflicts, unhealthy bureaucratic activities, and various complexities in decision-making [Telleen (1996)]. This applies even more to organisations in developing countries such as Pakistan that are in need of efficient ways to improve governance and enhance institutional reforms.

Penelitian ini bertujuan untuk mengidentifikasi faktor dominan yang menyebabkan turunnya produktivitas pada proses produksi Busana Muslim Rabbani Line 4A di CV. Y. Metode yang digunakan pada penelitian ini yaitu metode OMAX (Objective Matrix), FTA (Failure Tree Analysis) untuk mengidentifikasi faktor dominan yang meyebabkan turunnya produktivitas karena adanya pergantian desain produk, dan perbaikannya dengan metode SMED (Single Minute Exchange Of  Die). Hasil dari penelitian ini didapatkan faktor dominan penyebab turunnya produktivitas yaitu faktor jam kerja, dimana karena adanya pergantian desain menyebabkan semua mesin harus ada proses set-up. Berdasarkan metode SMED sebagai metode untuk perbaikan diketahui waktu set-up setiap mesin pembuatan busana muslim mengalami penurunan sebesar 7 menit/mesin dengan memisahkan internal set-up (kegiatan yang hanya dilakukan pada saat mesin berhenti)  dan eksternal set-up (kegiatan set-up yang dapat dilakukan saat mesin berjalan), waktu set-up sebelum penerapan SMED sebesar 551 menit/line (19 mesin), sedangkan waktu set-up sesudah penerapan SMED dapat diturunkan sebesar 133 menit/line, maka penurunan waktu set-up sebesar 24% setiap ada proses set-up mesin.

The Eu

The EU legal system, with its many hands and complex architecture, in which national and European powers are closely interwoven, requires a particular form of cooperation. This delicately developed cooperation may be influenced by the EU's ambition to take a statelike role in international relations. Indeed, the basic assumption underlying this Article is that it is not only the EU's complexity that influences the EU's external actions—usually seen as limiting the EU's capacity to speak with one voice—but also that the EU's external actions influence its internal set-up and cooperation practices. As a result of the EU's participation in international legal regimes, established organizational principles might come under pressure. Furthermore, within the complexity of the European legal order, the potential consequences could be more disturbing for stability than within the—monolithic, in comparison—structure of states.

Education Initiative

This article considers the ideational and political contexts in which Project 5-100, the Russian excellence in higher education initiative emerged, as well as the specificities of its organisational and behavioural model. While Project 5-100 has been studied in the academic literature as regards its efficiency and how it affected the performance and inner workings of the participating universities, the question of how the project came about and the characteristic traits of its internal set-up still remain largely overlooked. The study focuses on the involvement of local and international players, arguing that their successful and organic cooperation influenced both the architecture and the implementation of the project. This paper contributes to the literature on policy networks by showing that transnational actors do not necessarily undermine or challenge state power and can on the contrary help governments implement systemic change. Inspired by the international experience of establishing world-class universities, Project 5-100 was conceived and lobbied by a small but influential group of visionaries pushing for change who – acting in a concerted and purposive manner – acquired a novel and powerful capacity to use international expertise for the development of a key national project, capable of deeply transforming the country’s higher educational system.

Wave set-up is generally considered for the stability analysis of beaches, but not or not explicitly for the design of revetments. Based on large-scale model results with regular and irregular waves, it is shown in this paper that this is not justified. For this purpose, the wave set-up on a porous bonded revetment and the related internal set-up in the sand foundation below the revetment are analysed for different breaker types. The results particularly show that (i) considerable set-up values are obtained for almost all breaker types, (ii) a good correlation exists with the deep water wave length for both external and internal set-up and (iii) the internal set-up is significantly affected by the wave set-up on the slope. Empirical formulae for the prediction of the external and internal set-up are also proposed for both regular and irregular waves.

This paper discusses work done to find an estimate of the maximum achievable discharge burnup in an open cycle molten salt reactor (MSR). An in-development deterministic code (WIMS11) is used to create a model of a simple generic MSR, and the methodology employed is discussed. Some experimentation is done with regards to the internal set-up of the ‘unit cells’ within the core, which shows there is a strong link between this geometry and the achievable burnup. Work is done to quantify the effects of removing volatile fission products and implementing a two-batch refuelling scheme. Finally, an optimization process is carried out whereby the optimal proportion of graphite moderator within the core is found which balances power across the regions while maximising discharge burnup. Two fuels are tested, one which carries only 235U and 238U, and another which also carries 232Th. It is found that the maximum achievable discharge burnup is approximately 155 MWd/kg, which is considerably higher than modern PWRs, despite a lower enrichment and only two batches of fuel being used.

CNC machines have become popular in the manufacturing sector in the last three decades. It is still expensive to afford all aspects related to the operations of these machines. One important aspect is the programming stage, which requires a skilful programmer and an appropriate programming media. Hiring a good programmer is not the cheap and the best solution, while having a commercial programming media is also not affordable for SME in Indonesia. This research is focusing on the design and development of a program checker to see whether the program for a CNC turning machine is correct and ready to be fed to the machine. At once, this program is also capable of displaying cutting simulation of how the product is to be cut in the machine. Therefore, this program will help a small manufacturing company to avoid hiring an expensive expert or buying special programming media. This program is specifically developed for a CNC Okuma Howa ACT 3 turning machine. Some results show that the program can easily point out error location if there is a logical or syntax error in the NC program. Moreover, the simulation can be executed only if all errors have been corrected. This feature ensures that the simulation can run properly. To run the simulation, one has to set up some variables such as workpiece dimension, tool position with respect to the machine, and cutter dimension.

The authorization procedure required by law in Switzerland and the internal set-up at Roche for acquiring experimental animals has made a computerized system for monitoring authorizations and animal deliveries essential. The INQUIRE software program, which can be run on the central computer, was used to set-up databases with information on all personnel who place orders and perform experiments (PERI), authorization matters (BEWI), orders (ORDR), deliveries (SPED), animal species (SPEC), animal strains (STRE), populations (POPU) and the management of various data (BARA). The authorizations database (BEWI) permits sequential searches on specific questions. The animals ordered in the ORDR database are constantly updated in BEWI, thus ensuring that the authorized animal quotas are not exceeded. Expiry of an authorization or an unregistered experimenter will come to light in the course of the plausibility study. Through ORDR the experimenter has a good overview of the animals that he has ordered or have been ordered for him, and he can select the most appropriate strain or population for his studies in STRE or POPU, which contain data on the genetic and physiological characteristics as well as the breeding and keeping of all sublines and stocks. Realization of the IFIS project has made it a simple matter to keep a check on the legal requirements pertaining to animal experimentation and to update the information and evaluate the entire stock of data at any time.

Three techniques were incorporated for drying clay-rich specimens: air-drying, freeze-drying and critical point drying. In air-drying, the specimens were set out for several days to dry or were placed in an oven (80°F) for several hours. The freeze-dried specimens were frozen by immersion in liquid nitrogen or in isopentane at near liquid nitrogen temperature and then were immediately placed in the freeze-dry vacuum chamber. The critical point specimens were molded in agar immediately after sampling. When the agar had set up the dehydration series, water-alcohol-amyl acetate-CO2 was carried out. The objectives were to compare the fabric plasmas (clays and precipitates), fabricskeletons (quartz grains) and the relationship between them for each drying technique. The three drying methods are not only applicable to the study of treated soils, but can be incorporated into all SEM clay soil studies.

Freeze-etching electron microscopy is currently one of the best methods for studying molecular organization of biological materials. Its application, however, is still limited by our imprecise knowledge about the perturbations of the original organization which may occur during quenching and fracturing of the samples and during the replication of fractured surfaces. Although it is well known that the preservation of the molecular organization of biological materials is critically dependent on the rate of freezing of the samples, little information is presently available concerning the nature and the extent of freezing-rate dependent perturbations of the original organizations. In order to obtain this information, we have developed a method based on the comparison of x-ray diffraction patterns of samples before and after freezing, prior to fracturing and replication.Our experimental set-up is shown in Fig. 1. The sample to be quenched is placed on its holder which is then mounted on a small metal holder (O) fixed on a glass capillary (p), whose position is controlled by a micromanipulator.
