On convergence of generators of equilibrium dynamics of hopping particles to generator of a birth-and-death process in continuum

We deal with two following classes of equilibrium stochastic dynamics of infinite particle systems in continuum: hopping particles (also called Kawasaki dynamics), i.e., a dynamics where each particle randomly hops over the space, and birth-and-death process in continuum (or Glauber dynamics), i.e., a dynamics where there is no motion of particles, but rather particles die, or are born at random. We prove that a wide class of Glauber dynamics can be derived as a scaling limit of Kawasaki dynamics. More precisely, we prove the convergence of respective generators on a set of cylinder functions, in the $L^2$-norm with respect to the invariant measure of the processes. The latter measure is supposed to be a Gibbs measure corresponding to a potential of pair interaction, in the low activity-high temperature regime. Our result generalizes that of [Finkelshtein D.L. et al., to appear in Random Oper. Stochastic Equations], which was proved for a special Glauber (Kawasaki, respectively) dynamics

Dal Cassiodoro dell’Historia Gothorum a quello delle Institutiones

L’autore esamina la presenza di Virgilio in Cassiodoro. Cassiodoro esprime una dinamica di appropriazione ambivalente: mentre nei suoi testi di esegesi cristiana le sue allusioni a Virgilio sono intenzionalmente vaghe, nella sua opera storiografica l’auctoritas di Virgilio è ripetutamente insistita. Infatti, in quest’ultima Cassiodoro cerca di raggiungere un diverso obiettivo: Virgilio serve da fonte autorevole per presentare i Goti sia come una razza che condivide un comune lignaggio divino con i romani, sia come un popolo di antiche tradizioni le cui origini sono nobilitate dalla loro menzione nell’Eneide 3.35 [Gradivus] Geticis qui praesidet arvis.The author discusses the presence of Vergil in Cassiodorus. Cassiodorus displays an ambivalent dynamic of appropriation: whereas in his texts on Christian exegesis his allusions to Vergil are intentionally vague, in his historiographical works the auctoritas of Vergil is repeatedly stressed. Indeed, in the latter Cassiodorus seeks to attain a different goal: Vergil serves as the authoritative source in order to present the Goths both as a race sharing a common divine lineage with the Romans and as people of ancient traditions whose origins were ennobled by a mention at Aeneid, 3.35 [Gradivus] Geticis qui praesidet arvis

Monsoon fishery of juvenile ginger prawns at Little Rann of Kutch, Gujarat in relation to environmental parameters

Juveniles of ginger prawn, Metapenaeus kutchensis (George, George and Rao, 1963), form monsoon fishery in shallow estuarine waters of the Little Rann of Kutch. The catch data were collected from Tikar, Mandrakhi, Cherowari and Surajbari landing centres during 2004 to 2009. The annual average catch was 2406 t, of which the bulk was contributed by Mandrakhi and Tikar. The catch correlated well with the amount of rainfall (r = 0.97). The length-weight relationships were expressed as: Log W = -2.367 + 3.1204 log TL for males (r = 0.81) and Log W = -2.868 + 3.7098 log TL for females (r = 0.88). All the water quality parameters including ammonium nitrogen, nitrate nitrogen and phosphate phosphorus were within safe limits and congenial for growth of ginger prawn juveniles and post-larvae. The water and sediment bacteriology revealed that both proteolytic and lipolytic bacteria were present in considerable quantities for efficient recycling. The chemical and biological parameters of water apart from monsoon rains, appear to contribute to the rapid growth of this species from post-larvae to juveniles

Rare record of rainbow runner Elegatis bipinnulata in trawl catches of Veraval

A small quantity of the carangid rainbow runner Elegatis bipinnulata which can easily be mistaken to be a longer mackerel or seer fish was landed on 23.11.2000 at Bhidia trawl landing centre. This species had no scutes on the lateral line, instead had pored scales with rainbow like colour pattern over the body, shape very much resembled to that of Sconiberomoras guttatus

Bumper landings of Abalistes stellatus (Lacepede. 1798)

Although trigger fishes are obtained in stray numbers during trawl catches, unusually large specimens are observed in the long trip trawlers operating at 60-100 mts depth. The size ranged from 38 to 43 cm and the catch from 50 to 100 kg/boat. A record landing of about 185.5 tonnes was estimated during the year 2000 at Veraval. The samples collected on 24.11.2000 were identified as the starry triggerfish, Abalistes stellatus (Lacepede, 1798)

Improved mechanisation in dolnetting along the Saurashtra coast

The dolnetters of Jaffrabad, Rajapara and Nawabunder until 2000 were using engine drive for transport and other fishing operations (shooting, piling and hauling). This was done manually and required 6-9 persons per trip with increased effort and reduced catches which necessitated multiday operations and multinet/multihaul operations

On the unusual landing of juvenile black pomfret at Veraval and Mangrol landing centre of Gujrat

Pomfrets form an Important component in the fishery off Mangrol and Veraval. They are landed by trawl nets and monofilament gill nets. The silver pomfret Pampas argenteus Is locally called "Vichhuda" and the black pomfret, Formio niger is called "Halva". The former dominates the pomfret fishery with peak landings in the monsoon and post monsoon period. The black pomfret does not show any regular pattern of landing

The unusual landings of Juveniles of Decapterus russelli and Rastrelliger kanagurta in trawl catches of Veraval

Caputre of fish Juveniles in trawl nets is a common and regular phenomenon ever since the cod end mesh size has been reduced to less than 10 mm. Generally the cod-end catches are a mixture of juveniles of several species of finflshes and shellfishes, along with a host of inedible benthic biota. The occurance of a single species in significantly large quantities is seldom found or reported

COMBINATION THERAPY: DUAL DRUG-LOADED SUPERPARAMAGNETIC IRON-OXIDE NANOPARTICLE FOR TARGETED DRUG DELIVERY AND TREATMENT OF CANCER

Lung cancer is the most occurring form of cancer of all ages in the United States after breast cancer. Many treatments are currently available in the market to treat cancer, but they all have some side effects. The concept of nanomedicine-based targeted drug delivery has been developed to overcome the limitations of current treatment. The advantages of this method of treatment include biocompatibility, significant toxicity towards cancer cells, immediate drug response, and fewer side effects. For the specific treatment of A549 lung cancer cells, polyacrylic acid (PAA) coated Iron Oxide Nanoparticle (IONP) were introduced for magnetic resonance imaging (MRI) of lung cancer. To make these nanoparticles specifically target A549 cells, a folate receptor targeting ligand was conjugated on the surface through carbodiimide chemistry. The novel approach of combining two drugs, doxorubicin and fingolimod, was designed for this study. Drugs were co-encapsulated within the PAA coating of Magnetic Nanoparticles (MNPs) by the solvent diffusion method. Doxorubicin was encapsulated with MNPs to target the tumor cells to compare the synergistic effect of combination therapy on a tumor site at different time-points. Significant synergistic cell killing was accomplished in doxorubicin and fingolimod dual drug-loaded vesicles in lung cancer cells. This combination therapy\u27s therapeutic efficacy over a single drug usage was confirmed using several cell-based assays such as a comet, ROS, cell migration, and apoptosis

Mediterranean visceral leishmaniasis in immunocompetent children. Report of two cases relapsed after specific therapy

Visceral leishmaniasis (VL) is endemic in areas bordering the Mediterranean Sea (Spain, Italy, France, Greece, Morocco, Tunisia) where it is caused by Leishmania infantum and is transmitted by the bite of a hematophagous sandfly belonging to Phlebotomus spp.; the dog constitutes the main reservoir of infection. Two cases of VL in immunocompetent children are described. Both patients lived in endemic areas for leishmaniasis (Sicily) and at admission were febrile, pale and had splenomegaly. In both patients anti-leishmania antibodies were present and a definitive diagnosis was confirmed by demonstration of leishmania parasites by microscopy or polymerase chain reaction (PCR) in the bone marrow aspirates. The use of PCR performed on peripheral blood has been reported to be highly sensitive for the diagnosis and follow-up of children with VL. One patient was treated with N-dimethylglucamine, Glucantim, the other one with liposomal Amphotericin B (AmBisome). Both had symptomatic relapses 3 months later, and recovered following re-treatment with AmBisome administered intravenously at a dosage of 3 mg/Kg for ten consecutive days. The patients were monitored for one year after treatment was complete
