BACKGROUND The paca is a South American rodent with potential as a commercial food animal. We examined paca placenta as part of a wider effort to understand the reproductive biology of this species. METHODS Thirteen specimens between midgestation and term of pregnancy were studied by light and transmission electron microscopy. RESULTS The placenta is divided into several lobes separated by ...

A dacryolith was discovered in the lacrimal sac during a dacryocystorhinostomy for chronic dacryocystitis in which there was mucocele formation. Morphological examination confirmed the presence of an eyelash at the centre of the stone and electron microscopy demonstrated the presence of fungi (Candida sp.) in a matrix which was of markedly vairable morphology. The mechanism by which a hair ente...

the main purpose of this research was to investigate the factors influencing on computer attitudes of agricultural extension agents. the target population consisted of all extension agents of agricultural engineering and council services companies in kermanshah township (n= 85).  a sample of 70 agents was selected through a stratified random sampling. based on the results, the majority of agent...

A complete complementary/prime/shifted prime (CPS) code family for the optical code-division multiple-access (OCDMA) system is proposed. Based on the ability of complete complementary (CC) code, the multiple-access interference (MAI) can be suppressed and eliminated via spectral amplitude coding (SAC) OCDMA system under asynchronous/synchronous transmission. By utilizing the shifted prime (SP) ...

: Optical code division multiple access OCDMA is one of the promising optical technologies due to its worth-mentioning features, such as asynchronous access, and high security. In this paper, author performed an analytical-based comparison between three commonly used spectrum amplitude coding SAC-based codes, namely: Modified Frequency Hopping MFH, Hadamard, Enhanced Double Weight EDW. The was ...

THE USUAL approach to the lacrimal sac and the area around is through the standard curved incision, with the centre of the concavity about 2-3 mm. from the inner margin of the inner canthus. It can be termed "adequate", although, to get a good view and to have freedom of manoeuvre, the incision has often to be widely stretched in all directions. Even then, one is often working in a fairly deep ...

background: initiating a national poisoning information centre (pic) in estonia took about 12 years of challenging work on research, training and attracting governmental support and funding. in this study we described the establishment process and the profile of phone calls in the first year which the pic started to be available full time (24h/day 7days/week).  methods: this was a descriptive r...
