The caridean shrimp Ogyrides wickstenae sp. nov. is described from Mazatlán, Pacific coast of Mexico. The new species is most closely related to O. tarazonai Wicksten & Méndez, 1988 and O. hayi Williams, 1981, sharing with them a single spine on the dorsal midline of the carapace. However, the new species can be distinguished from the two allied species by the presence of a single small spine o...

Are pelagic species such as sharks and tuna distributed homogenously or heterogeneously in the oceans? Large assemblages of these species have been observed at seamounts and offshore islands in the eastern tropical Pacific, which are considered hotspots of pelagic biodiversity. Is the species distribution uniform at these hotspots or do species aggregate at a finer spatial scale at these sites?...

(1) The mathematical calculations relating spectrophotometric data with the data of Allard et al. (4, 5) on mitochondrial counts, is presented. Such a calculation indicates that an "average mitochondrion" from rat liver would contain about 17,000 molecules of each cytochrome pigment. (2) Hematocrit determinations relating respiratory pigment content for mitochondria isolated from a variety of t...

SCguin, Allard and Bhargava [ 1,4] have recently introduced a class of codes (hereafter called SAB-codes) providing error protection in byte-oriented information systems. In the case of bytes of 8 bits, these authors have proposed a l-error correcting, 2-error detecting linear code of length 8 x 24 and dimension 7 x 23 with one parity byte which may correct any double error affecting two differ...

this is a commentary on gilbert and colleagues’ (1) paper on morality and markets in the national health service (nhs). morality and values are not ephemeral qualities and universal healthcare is not simply an aspiration; it has to be enshrined in law. the creation of the uk nhs in 1948 was underpinned by core legal duties which required a system of public funding and delivery to follow. the mo...

A 22 year old patient with severe aplastic anaemia responded to antilymphocytic globulin but developed recurrent fever despite treatment with steroids and then antibacterial, antifungal, and antituberculous drugs. There was progression, with severe joint pains and immobility associated with radiological evidence of a symmetrical destructive process. A bone marrow specimen showed no evidence of ...

External noise paradigms are widely used to characterize sensitivity by comparing the effect of a variable on contrast threshold when it is limited by internal versus external noise. A basic assumption of external noise paradigms is that the processing properties are the same in low and high noise. However, recent studies (e.g., Allard & Cavanagh, 2011; Allard & Faubert, 2014b) suggest that thi...

Four new species of Tambinia Stål (Hemiptera: Fulgoromorpha: Tropiduchidae), Tambinia conussp. n. (Papua New Guinea), Tambinia maculasp. n. (Malaysia: Borneo), Tambinia robustocarinasp. n. (Malaysia: Sabah) and Tambinia sexmaculatasp. n. (Australia: Kuranda) are described and illustrated from the Pacific region. The diagnostic characters of this genus are redefined. A checklist and a key to the...

– Every student and staff member authorized as an IS MU user can participate in enhancing the system and contribute to analysis of new applications. The system is to provide something interesting or useful for everyone. The access to the system must be transparent, i.e. all applications have web interface. Apart from around 15 thousand students (who use the system at least occasionally), IS MU ...
