Zeta Functions and Asymptotic Formulae for Preperiodic Orbits of Hyperbolic Rational Maps
Authors: Waddington Simon 
Published: July 2010

AbstractFor a hyperbolic rational map R of the Riemann sphere of degree d ≥ 2, restricted to its Julia set J(R), we define a zeta function ζR(s), which counts the prepenodic orbib of R, according to the weight function |R'| : J(R) → C. An analysis of the analytic domain of ζR(s), using techniques from symbolic dynamics, yields weighted asymptotic formulae for the preperiodic orbits of R. We describe an application to diophantine number theory.

AbstractWe investigate under which conditions an algebraic group G defined over a locally compact field k admitr a subgroup Γ⊂ G(k) which is dense in the Zariski topology, but discerte in the topology induced by the locally compact topology on k. For non—solvable groups we provide a complete answer.
Deep brain stimulation for essential tremor: A systematic review
Authors: Flora Eliana Della , Perera Caryn L. , Cameron Alun L. , Maddern Guy J. 
Published: July 2010

AbstractDeep brain stimulation (DBS) is a neurosurgical treatment, which has proven useful in treating Parkinson's disease. This systematic review assessed the safety and effectiveness of DBS for another movement disorder, essential tremor. All studies concerning the use of DBS in patients with essential tremor were identified through searching of electronic databases and hand searching of reference lists. Studies were categorized as before/after DBS or DBS stimulation on/off to allow the effect of the stimulation to be analyzed separately to that of the surgery itself. A total of 430 patients who had received DBS for essential tremor were identified. Most of the reported adverse events were mild and could be treated through changing the stimulation settings. Generally, in all studies, there was a significant improvement in outcomes after DBS compared with baseline scores. In addition, DBS was significantly better in testing when the stimulation was turned on, compared with stimulation turned off or baseline. Based on Level IV evidence, DBS is possibly a safe and effective therapy for essential tremor. © 2010 Movement Disorders Society

AbstractWe delineated the effects of magnetic field strength on signal intensities to facilitate the specific findings of multiple system atrophy (MSA). Fifteen patients with probable MSA were imaged by 0.35T fast spin‐echo (FSE), 1.5T FSE, and 3.0T FSE using a consistent protocol, testing all field strengths on the same day. Sixty patients with probable Parkinson's disease (PD) also underwent imaging. Moderate or marked hyperintensity at the dorsolateral outer putaminal margin, hyperintensity of the putaminal body, hypointensity relative to the globus pallidus at the dorsolateral putaminal margin, and infratentorial signal changes were evaluated as specific findings for MSA. As the field strength increased, the occurrence of hyperintensity both at the dorsolateral outer putaminal margin and of the putaminal body decreased, while the occurrence of hypointensity at the dorsolateral putaminal margin increased in MSA. The occurrence of uniform mild hyperintensity of the outer putaminal margin was evident in 7% at 0.35T, 40% at 1.5T, and 47% at 3.0T in MSA and in 5% at 0.35T, 60% at 1.5T, and 75% at 3.0T in PD. However, no PD patients showed hyperintensity at the dorsolateral outer putaminal margin and that of the putaminal body. Putaminal magnetic resonance imaging (MRI) findings in MSA were altered considerably by magnetic field strength. The severity and distribution of signal changes are important for assessing putaminal MRI findings in MSA. © 2010 Movement Disorders Society
Effects of certain dietary regimes and exteroceptive factors associated with the developing pupa of Tribolium castaneum (HBST.) on the insect's reproductive programming
Authors: Narayan Singh R. , Krishna S. S. 
Published: July 2010

AbstractThe reproductive ability of female Tribolium castaneum to lay more eggs, all fertile, when reared on whole wheat flour than on semolina remained unaffected despite various types of situations — solitary, single paired (1 male, 1 female) and grouped (5 females per group) — experienced by the beetle during its pupal stage. However, single paired pupal condition, maintained with or without their concerned larval food (whole wheat flour or semolina), produced females yielding maximal egg output.

Authors: Lieder Ulrich 
Published: July 2010

The Life‐work of F. E. Rühe and his Contributions to CladocerologyFRIEDRICH EDUARD RÜHE (born Febr. 9, 1888, died by war Sept. 22, 1915) was one of the most outstanding cladocerologists of the so‐called Berlin School of Cladocerology. In the years 1909–1915 RÜHE published 10 papers, exclusively on Crustacea, in the majority on the bosminid species, arranged in the subgenus Eubosmina today (Crustacea: Cladocera, Bosminidae). Side by side with the papers by G. O. SARS and W. LILLJEBORG the main paper by RÜHE (1912a) on Bosmina coregoni in the Baltic Lake District is a milestone in the research in bosminids. 75 years after he has published his papers they are quoted frequently in the international literature – an evidence for the great and unchanged importance of his work. It is the aim of the present paper to appreciate the papers and the thoughts of RÜHE in a present day view on occasion of his centenary.
Effect of Different Varieties of Gram on Growth, Development and Reproduction of Heliothis armigera (Hübner) (Lepidoptera: Noctuidae)
Authors: Tripathi Shri Rang , Singh Rajesh 
Published: July 2010

AbstractHeliothis armigera was reared on four varieties of gram, namely Radhe, Desi, K168 and K4. Growth was studied under laboratory conditions from January to March 1986. The weight acquired by the mature larvae showed variation among the tested food plants. Weight of the pupa also varied in response to rearing on different varieties of gram. Radhe induced the quickest pupation. The emergence of the insect varied from 61–92% among the tested varieties of gram. Fecundity also differed markedly from variety to variety.

Effect of Larval Crowding on Development, Growth and Reproduction of Earias vittella (F.) (Lepidoptera: Noctuidae)
Authors: Tripathi Shri Rang , Singh Arti 
Published: July 2010

AbstractEffects of different levels of larval density (1, 5, 10, 15, 20, 25 larvae/container) on development, growth and reproduction of Earias vittella were examined under laboratory conditions when the temperature ranged from 22–33°C and R. H. varied from 57–91%‐Larval survival was found to be negatively correlated to the level of density. However, it reduced the larval and pupal weights. Crowding also decreased the fecundity of adults. Hatching of the eggs laid by the females was not affected by the larval crowding.

Camouflaging Behaviour and the Effect of Decamouflaging on Behaviour and Development of Acanthaspis pedestrisStål in Solitary and Crowded Conditions (Insecta, Heteroptera, Reduviidae)
Authors: Ambrose Dunston P. , Sahayaraj K. 
Published: July 2010

AbstractThe present investigation deals with the camouflaging behaviour and its effect on the biology and the behaviour of Acanthaspis pedestris Stål in solitary and crowded conditions. The effect of crowding is observed in 3 categories, such as, (a) one individual, (b) two individuals and (c) four individuals under two different conditions (a) camouflaged and (b) decamouflaged. A. pedestris exhibits both natural and corpse camouflaging. The camouflaging efficiency is greater in the I instar and gradually diminishes in the older instars and it totally disappears in the adults. Crowding causes a decrease in the body weight and the particle carrying capacity. Both crowding and decamouflaging affects the ethology of camouflaging and the prey capturing time. Increased nymphal mortality and decreased stadial period are observed as functions of crowding and decamouflaging. Decamouflaging increases the adult longevity of A. pedestris in 1 individual male and 2 individuals female. Crowding causes an increase in the adult longevity of male in the 2 individuals group and causes a decrease in the 4 individuals group of decamouflaged individuals. Sex ratio of camouflaged individuals is biased. But in the decamouflaged one individual group the sex ratio is unbiased. The male biased sex ratio of the normal individuals becomes female biased as a function of crowding.
Prey Influence on the Laboratory Mass Rearing of Rhinocoris kumarii Ambrose & Livingstone, a Potential Biological Control Agent (Insecta, Heteroptera, Reduviidae)
Authors: Ambrose Dunston P. , Roseline Rani M. Sahaya 
Published: July 2010

AbstractThe relative importance of 6 different types of preys, viz., 1. Chrotogonus sp. 2. Musca domestica, 3. Bruchus theobromae, 4. Odontotermes obesus, 5. Camponotus compressus and 6. the mixture of above said five preys in the laboratory mass rearing of R. kumarii, a biological control agent, is assessed. Taking into consideration the development, fecundity and hatchability, B. theobromae is found to be the most suitable prey among all the test preys.The shortest stadial period is recorded for the nymphal instars fed with O. obesus and the longest stadial period is recorded for the nymphal instars fed with B. theobromae. The highest nymphal mortality is observed among the individuals fed with M. domestica and the lowest among the individuals fed with O. obesus. The adults emerged from the nymphal instars fed with Chrotogonus sp., B. theobromae, C. compressus and the mixture of preys are of male biased, whereas the adults emerged from the nymphal instars fed with M. domestica and O. obesus are of female biased. The longest adult longevity is observed among the individuals fed with B. theobromae and the lowest among the individuals fed with O. obesus. The shortest preoviposition period is observed among the individuals fed with B. theobromae and the longest preoviposition period is observed among the individuals fed with the mixture of preys. Regarding the fecundity, the highest fecundity is observed among the females fed with B. theobromae. The shortest incubation period is observed among the females fed with the mixture of preys. Maximum number of nymphs hatch from the eggs laid by the individuals reared on B. theobromae. B. theobromae, a pest of pulses, is found to be the most suitable prey for the laboratory mass rearing for the conservation and augmentation of R. kumarii.

Effects of Odours of Certain Plant Oils/Leaves on the Egg Hatchability in Corcyra cephalonica (Stainton) (Lepidoptera: Pyralidae)
Authors: Pathak P. H. , Krishna S. S. 
Published: July 2010

AbstractThe hatchability of eggs of Corcyra cephalonica, exposed during embryogenesis to the odours of certain selected plant oils (cedarwood, clove or eucalyptus) or leaves (eucalyptus or neem), was always less and it was minimal in an environment laden with clove oil aroma. Interaction of these eggs with eucalyptus oil odour for 12 hours daily between 6.00 hand 18.00 h instead of between 18.00 h and 6.00 h in a 4‐day experimental schedule led to a significant reduction in hatchability when compared with control data.
