Study of Noise pollution during Deepawali festival in Kolhapur city of Maharashtra, India
Lad R.J,Patil V.N,Raut P.D
Review of Research , 2012,
Abstract: Kolhapur city is a district place in the state of Maharashtra with population of 4,93,167. It is one of the emerging industrial and commercial city of Western Maharashtra. Problems of pollution along with noise pollution are increasing with time especially during the festival period. In the present study, continuous monitoring of noise levels was carried out during the three festive days of Deepawali in the month of November, 2009 at ten different sites within the Kolhapur city. On the basis of location these sites were grouped into industrial, commercial, residential and silent zones respectively. The results showed that there is an enhanced pressure of noise at all sites during the festival of light due to bursting of loud noise firecrackers. All the sites under study showed higher sound levelthan the prescribed limits of Central pollution Control Board (CPCB).

Abstract: A continental European earthworm, Kenleenus armadas sp. nov., is newly described from an introduction to a farm in Dublin, Ireland. Previously recognized as Aquitainian Prosellodrilus amplisetosus Bouché, 1972, the morphology and molecular characteristics rather indicate it as a taxon new to science. Its description has required revision of all prosellodrilid genera including Algerian subgenus Maghrebiella Baha & Bera, 2001 that is a permanently invalid homonym, here replaced with Cadanera nom. nov. A revised checklist is appended that holds Allolobophora festae Rosa, 1892 as a species incertae sedis pending review of the Cadanera type. This report brings the total earthworms known from Britain & Ireland to 72 species, including a new record of cosmopolitan Pithemera bicincta (Perrier, 1875) (Megascolecidae) from Dublin’s Botanic Gardens
Review of Criodrilidae (Annelida: Oligochaeta) including Biwadrilus from Japan.
Blakemore, R.J.
Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis , 2008,
Abstract: Palaearctic family Criodrilidae Vejdovsky, 1884 is briefly reviewed and revised to reabsorb Biwadrilidae Brinkhurst & Jamieson, 1971, monotypic for lacustrine/limnic Biwadrilus bathybates (Stephenson, 1917) based on examination of new Lake Biwa material from recent earthworm surveys. Comparison is with type species: Criodrilus lacuum Hoffmeister, 1845. Synonymy in Criodrilus of monotypic genus Hydrilus Qiu & Bouché, 1998 from Algeria is accepted but with provisional restoration of its type as Criodrilus ghaniae (Qiu & Bouché, 1998) comb. nov., if indeed it belongs in the Criodrilidae. Another recent taxon Guarani camaqua Rodríguez & Lima, 2007 from rice fields of Rio Grande do Sul, Brazil is syn. nov. of Criodrilus lacuum at species and genus level since its characteristics are easily embraced within interspecific variability. Moreover, the prior taxon, C. lacuum, was already known from its type-locality. Distribution, ecology and species associations of the criodrilids are briefly summarised including a report of C. lacuum maintained in a laboratory culture for >42 years (T. Timm pers. comm.). A key to species is provided.
Unravelling some Kinki earthworms (Annelida: Oligochaeta: Megadrili: Megascolecidae) - Part II
Blakemore, R.J.
Opuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis , 2010,
Abstract: Metaphire tanbode sp. nov. is found in rice paddy in Kinki plain at Lake Biwa and Amynthas yamade sp. nov. isfrom Hira range to the West. M. tanbode belongs to the M. hilgendorfi / A. tokioensis species-complex, while montane A. yamadeis comparable to both Amynthas aeruginosus-group and Duplodicodrilus schmardae-group. Genetic barcoding (mtDNA COI) viatypes is attempted. Taxonomic ‘housekeeping’ requires replacement of invalid homonyms: e.g. Pheretima montana Ishizuka, 1999(non type-species P. montana Kinberg, 1867) is renamed Amynthas nonmontanus; others are A. nonsilvestris, A. noninvisus, A.nonmonticolus and A. nonsetosus, noms. et combs. novae. Thus Pheretima Kinberg, 1867 s. stricto remains unrecorded from Japanwhile prior Amynthas Kinberg, 1867, and its derivative Metaphire Sims & Easton, 1972, are abundant and diverse. Family andgeneric level definition and placement of Oriental pheretimoids are restated for the benefit of current workers and for novicefield-ecologists. Surveys of below-ground biodiversity of rice paddy in Lake Biwa is compared to more natural habitats aroundLake Pedder in Western Tasmanian Wilderness Area, and co-incidentally, both have 21 recorded earthworm species. Thus claimsfrom various countries of less than six species per location are contraindicated by thorough eco-taxonomic methods yieldingmore representative results.
Geology of the Sabie River Basalt Formation in the Southern Kruger National Park
R.J. Sweeney
Koedoe : African Protected Area Conservation and Science , 1986, DOI: 10.4102/koedoe.v29i1.523
Abstract: The Sabie River Basalt Formation (SRBF) in the central Lebombo is a virtually continuous sequence of basaltic lavas some 2 500 m thick that was erupted 200 - 179 Ma ago. Flows are dominantly pahoehoe in character and vary from 2 m to 20 m in thickness. Dolerite dykes cross-cutting the basalt sequence probably represent feeders to this considerable volcanic event. Volcanological features observed within the SRBF are described. Two chemically distinct basaltic magma types are recognised, the simultaneous eruption of which presents an intriguing geochemical problem as to their origins.
Prey selection of lions Panthera leo in a small, enclosed reserve
R.J. Power
Koedoe : African Protected Area Conservation and Science , 2002, DOI: 10.4102/koedoe.v45i2.32
Abstract: Annual trends in numbers of ungulate species on a 15 km2 reserve from 1993 to 1998, were evaluated in the context of lion Panthera leo reintroduction during 1996, and subsequent predation by them. The ungulate prey base was enumerated annually by aerial counts and a road count that took place during 1998. The lion prey record was obtained from direct observations of a radio-located pride of eight lions and daily reserve management records. All ungulate species that underwent precipituous declines were also the most important prey to lions, comprising over 80 % of their prey, and they were preyed upon according to their availability. Lion predation was causal for the declines in wildebeest Connochaetes taurinus, Blesbok Damaliscus pygargus phillipsi and Warthog Phacochoerus africana, while the decline in Kudu Tragelaphus strepsiceros was only partly ascribed to lions, as other non-lion related mortality sources were identified. The only ungulate species to increase subsequent to lion reintroduction was the Impala Aepyceros melampus, which was furthermore under-selected by lions. The uncontrolled population growth of Impala could have elicited ecological degradation, and it was advised to either not stock Impala, or otherwise control their numbers if lions are unable to do so. Lion hunting success and kill rate, were 21 % (n = 63) and 1 kill/4.4 days, respectively. Three bushpigs Potamochoerus larvatus were killed but not utilised,and this finding is corroborated by an intensive study in Kwazulu-Natal, and this aversion is discussed. Predators can cause unprecedented declines of their prey where the prey are confined to small reserves that have no refuge from predation. On an annual basis, prey may need to be augmented to sustain predators on small reserves

Abstract: ENGLISH ABSTRACT: OThe World Health Organization (WHO) lists noise-induced hearing loss (NIHL) among the most critical global health concerns, given the high NIHL compensation statistics and a figure of up to 10,000 noise-related deaths each year. Industrial engineers / operations managers are now confronted with a serious challenge to control firstlevel noise in a modern engineering context to ensure that machines are quiet and administrative controls are well maintained. While noise continues, however, second-level noise control (hearing conservation) needs to be effective. To this end, a new management approach, re-engineering, redesign, and new hearing conservation programme (HCP) technology are required. The focus of this report is on an HCP model based on new HCP technologies (and management approaches) and a quality management method referred to as ‘verification methodology’. AFRIKAANSE OPSOMMING: Die wêreldgesondheidorganisasie (WHO) lys NIHL (geraasdoofheid) onder die mees kritieke globale gesondheidsprioriteite, gegewe die ho NIHL kompensasiestatistiek en die ongeveer 10,000 geraasverwante sterftes per jaar. Bedryfsingenieurs en operasionele bestuurders word nou gekonfronteer met hierdie ernstige uitdaging wat beteken dat eerste vlak geraasbeheer in die konteks van moderne ingenieurswese gedoen moet word sodat masjiene gestil word en administratiewe beheermaatre ls goed in stand gehou word. Terwyl geraas voortduur, moet tweede vlak geraasbeheer (gehoorkonservering) effektief wees, wat ‘n nuwe bestuursbenadering, heringenieuring (“re-engineering”), herontwerp, en nuwe gehoorkonserveringsprogramtegnologie vereis. Die fokus van hierdie artikel is op ’n gehoorkonserveringsmodel gebaseer op nuwe gehoorkonserveringstegnologie (en bestuurs-benaderings) en ’n gehaltebestuur-metode wat as ’n verifikasiemetodologie verwys word.
Sphincter repair: Its present place
Nicholls R.J.
Acta Chirurgica Iugoslavica , 2004, DOI: 10.2298/aci0402027n
Abstract: Faecal incontinence has become a condition of interest only in the last 30 years. In 1970 at St Mark’s Hospital, there were four admissions and over the next 20 years this had risen to 55 per year. Today faecal incontinence forms a significant part of colorectal practice. The original approach in the 1970s over a 20 year period was sphincter repair. Gynaecologists and general surgeons had for many years been occupied in the reconstruction of the anal sphincter after localized traumatic injury. In the 1970s, diffuse weakness of the pelvic floor was identified and characterized by neuromuscular histology to show evidence of denervation.
Salvage surgery after restorative proctocolectomy
Nicholls R.J.
Acta Chirurgica Iugoslavica , 2004, DOI: 10.2298/aci0402023n
Abstract: Restorative proctocolectomy is now the elective surgical procedure of choice for most patients with ulcerative colitis or familial adenomatous polyposis. There are four causes of failure including acute and chronic sepsis, poor function for mechanical or functional reasons, mucosal inflammation (including pouchitis and retained rectal mucosa) and neoplastic transformation. Failure rates themselves range from 5% to nearly 20%. Followed over a period of 20 years, the failure rate can be summarised approximately as 5% at five years, 10% at ten years and 15% at 15 years.
