The language was designed to be as similar to BASIC as it could be and still incorporate special functions that can be used by the user. The compiler is a two-pass compiler that generates intermediate code which is executed on the PCL processor task. The main part of the system is the Intel 310-35 microcomputer system. The language used to develop the PCL compiler was PL/M-86; the operating system is iRMX-88 Intel. The authors explain the design and implementation of the PCL language and the compiler for the language

This was done using a sample database which would realistically contain ordalt data, casrep data, and ship locations. The database was interfaced to a computer graphics program which monitored ship movement throughout the world and supplied information from the database whenever requested. The authors discuss the hardware and software used to implement the project. In particular, the IBM color/graphics adapter and the Paradox relational database software are described in some detail

Methods: Postswim blood lactate concentration, V O 2 , and rating of perceived exertion were measured. Average stroke length and rate, and breakout distance were determined for each swimming trial. Passive drag and buoyant force were also determined on swimmers while wearing both suits. Results: Swimmers swam at a higher mean velocity while wearing the FS (pooled mean % difference ϭ 2%), but this was accompanied by a significant increase in V O 2 (4% difference, P Ͻ 0.05) and blood lactate concentration (10% difference, P Ͻ 0.05). Comparison of physiological responses at standardized freestyle swimming speeds of 1.4 and 1.6 m·s Ϫ1 revealed no significant difference between the two suit conditions. Passive drag of the swimmers while being towed was not significantly different between the suits. Swimmers were significantly more buoyant while wearing the brief-style suit than the FS suit (P Ͻ 0.05). Conclusion: These findings provide no evidence of either physical or physiological benefits of wearing these suits during submaximal freestyle swimming.

This is possibly achieved through an interaction between HPV oncogenic proteins and some cell cycle regulatory genes. However, the exact pathogenetic mechanisms are not well defined yet.METHODS: We investigated 110 subjects (43 invasive squamous cell carcinoma (ISCC), 38 CIN III, 11 CIN II, 18 CIN I) confirmed to be positive for HPV16 and/or 18 as well as 20 normal cervical tissue (NCT) samples for abnormal expression of cyclin D1, cyclin E, CDK4, cyclin inhibitors (p21 (waf), p27, p16 (INK4A)) and Ki-67 using immunohistochemistry and differential PCR techniques.RESULTS: There was a significant increase in the expression of Ki-67, cyclin E, CDK4, p16 (INK4A) (p=0.003, 0.001, 0.001) and a significant decrease in p27 (Kip1) from NCT to ISCC (p=0.003). There was a significant correlation between altered expression of p27 (KIP1) and p16(INK4A) (p<0.001), cyclin D1 and CDK4 (p=0.001), cyclin E and p27 (Kip1) (p=0.011) in all studied groups. In ISCC, there was significant relationship between standard clinicopathological prognostic factors and high Ki-67 index , increased cyclin D1 and cyclin E, reduced p27 (Kip1) and p21 (waf).CONCLUSION: 1) Aberrations involving p27 (KIP1), cyclin E, CDK4 and p16 (INK4A) are considered early events in HPV 16 and 18-associated cervical carcinogenesis (CINI & II), whereas cyclin D1 aberrations are late events (CINIII & ISCC) 2) Immunohistochemical tests for p16 (INK4A) and cyclin E could help in early diagnosis of cervical carcinoma 3) Only FIGO stage, cyclin D1, p27 (Kip1) and Ki-67 are independent prognostic factors that might help in predicting outcome of cervical cancer patients.

Many problems and challenges still exist in distributing and executing applications in NHW such as: a. Creating and developing a programming environment that allows a single application task to be efficiently executed, shared, and ported among the various computers in the heterogeneous suite. b. A suitable mapping technique in which one can map an arbitrary heterogeneous tasks onto an arbitrary heterogeneous suite. c. Tasks need to be assigned so that the overall execution time is minimized, load imbalance is avoided, and accuracy of the result is maintained. d. Since the users can select a group of computers to run their own applications, the load on some machines can vary and an intelligent technique is necessary for migrating tasks between machines. In this paper, most of the problems of programming in a NHW will be addressed and a new approach that overcomes some of these problems will be explained. The new approach supports parallel programming on top of the clusters of NHW where some of the clusters are running a shared memory technique and others do not. The approach uses a messagepassing paradigm to communicate between machines of different clusters.

The PC serves as the data acquisition controller of a polled multidrop network that retrieves information from input terminals. The PC server simultaneously receives data from any combination of terminals on the network. It then updates a local SQL database, prompts the operator at the terminal for the next bit of information, while allowing access to the database from users connected to the server via a local area network. This system was developed to replace an out dated inventory tracking and control process which is currently in use by a local manufacturing company. The system presented will provide greater efficiency and productivity to the company by allowing its employees access to an inventory database that is updated in real-time. The use of a multitasking operating system and modern networking methods are the tools that will provide the company with the ability to keep its employees on top of inventory issues. This paper illustrates the practicality and benefits of taking advantage of the multitasking, networking, and processing capabilities of modern computers and operating systems
