- Description:
- Cucolepis gen. n. is erected as monotypic for Cucolepis cincta sp. n., a new species of cyclophyllidean cestode of the family Paruterinidae. The new species is described from the squirrel cuckoo, Piaya cayana Lesson (Aves: Cuculiformes), taken from two localities in Paraguay in 1984 and 1985. This new genus is most similar to the genus Triaenorhina Spasskii et Shumilo, 1965 in terms of the hook morphology and large epiphyseal structures extending from both the handle and guard, but differs in several aspects of the strobilar morphology, such as the shape of the cirrus sac, genital atrium, uterus and paruterine organ. The strobilar morphology of the new genus strongly resembles that of the genus Francobona Georgiev et Kornyushin, 1994, especially the shape of the cirrus sac and genital atrium, yet Francobona spp. lack the developed epiphyseal structures observed in species of Cucolepis and Triaenorhina. Previous records and the nature of parasite-host associations between cuculiform birds and their cestode parasites are discussed.

- Language:
- English
- Description:
- A new species of parasitic nematode, Cucullanus oceaniensis sp. n., is described from the intestine of the giant mottled eel Anguilla marmorata (type host) from Futuna Island (Wallis and Futuna Islands, Polynesia) and from A. marmorata and Anguilla sp. (cf. obscura) from Fiji Islands (Melanesia, South Pacific). The main distinguishing characteristics are the length of spicules (668-1,020 µm), situation of deirids (slightly anterior to the oesophago-intestinal junction) and the excretory pore (some distance posterior to the end of oesophagus), and the arrangement of caudal papillae in the male. It is the third known species of Cucullanus from Oceania and the first one reported from freshwater eels in the region of South Pacific. Cucullanus faliexae Morand et Rigby, 1998 is considered a junior synonym of Cucullanus australiensis Baylis, 1927.

- Language:
- English
- Description:
- A new nematode species, Cucullanus pargi sp. n., is described from the intestine and pyloric caeca of the grey snapper, Lutjanus griseus (Linnaeus), off the southern Quintana Roo coast, Mexico. This species shows similar morphological features as cucullanids occurring in marine and brackish-water fishes; however, it differs from all other species in the length of spicules, arrangement and number of caudal papillae, position of the excretory pore and deirids. Cucullanus pargi is the third species of this genus described from fishes in Mexico and the second one from Mexican marine fishes.

- Type:
- model:article and TEXT
- Subject:
- chlorophyll, grain, irradiance, net photosynthetic rate, photooxidation, photosynthetic characteristics, photosystems 1 and 2, ribulose-1,5-bisphosphate carboxylase, shoot dry mass, and superoxide dismutase
- Language:
- Multiple languages
- Description:
- Forty-four genotypes from the rice germplasm were identified under photoinhibition/photooxidation and shade conditions and divided into four basic types: (1) cultivars tolerant to both photooxidation and shading, (2) cultivars tolerant to photooxidation but sensitive to shading, (3) cultivars tolerant to shading but sensitive to photooxidation, and (4) cultivars sensitive to both photooxidation and shading. Photosynthetic characteristics of a cultivar tolerant (cv. Wuyugeng 3) and a cultivar sensitive (cv. Xiangxian) to photooxidation and shading were compared. The photochemical efficiency (Fv/Fm) of photosystem 2 (PS2) and the content of PS2-D1 protein in the tolerant cultivar Wuyugeng 3 decreased less under photooxidative conditions as compared with Xiangxian. Under similar conditions, superoxide dismutase was induced rapidly to a higher activity and the active oxygen (O-) built up to a lower level in Wuyugeng 3 than in Xiangxian. Net photosynthetic rate (PN) decreased by 23 % in Wuyugeng 3 vs. 64 % in Xiangxian. Shading (80 %) during the booting stage caused only small decreases (7-13 %) in ribulose-1,5-bisphosphate carboxylase activity and PN in Wuyugeng 3 but severe decreases (57-64 %) were observed in Xiangxian which corresponded to the decreases in grain yield of the two cultivars (38 and 73 %, respectively). We described a simple and effective screening method and physiological basis for breeding crops for enhanced tolerance to both high and low irradiance. and Demao Jiao, Xia Li.

- Description:
- Cotton (Gossypium hirsutum L.) yields are impacted by overall photosynthetic production. Factors that influence crop photosynthesis are the plants genetic makeup and the environmental conditions. This study investigated cultivar variation in photosynthesis in the field conditions under both ambient and higher temperature. Six diverse cotton cultivars were grown in the field at Stoneville, MS under both an ambient and a high temperature regime during the 2006-2008 growing seasons. Mid-season leaf net photosynthetic rates (PN) and dark-adapted chlorophyll fluorescence variable to maximal ratios (Fv/Fm) were determined on two leaves per plot. Temperature regimes did not have a significant effect on either PN or Fv/Fm. In 2006, however, there was a significant cultivar × temperature interaction for PN caused by PeeDee 3 having a lower PN under the high temperature regime. Other cultivars' PN were not affected by temperature. FM 800BR cultivar consistently had a higher PN across the years of the study. Despite demonstrating a higher leaf Fv/Fm, ST 5599BR exhibited a lower PN than the other cultivars. Although genetic variability was detected in photosynthesis and heat tolerance, the differences found were probably too small and inconsistent to be useful for a breeding program., W. T.

- Subject:
- body, philosophy of dance, gesture, plane of immanence, metalanguage, Merce Cunningham, and Giles Deleuze
- Language:
- Czech
- Description:
- An essay by the contemporary Portuguese philosopher José Gil addresses the prominent American choreographer and dancer Merce Cunningham’s conception of dance. Gil emphasizes that Cunningham approaches dance in a way that is fundamentally different from the traditional mimetic and expressive paradigm. With the help of Giles Deleuze’s observations, Gil proves that even in the case of dance shorn of the faculty to represent and express emotional contents, we can talk about units of dance, about their meaning and unity, and thus about the language of dance. Gil spells out this idea by showing a parallel between dance, in Cunningham’s conception of it, and modern painting. and Esej současného portugalského filosofa Josého Gila se zabývá pojetím tance u významného amerického choreografa a tanečníka Merce Cunninghama. Gil zdůrazňuje, že Cunningham pojímá tanec způsobem, který se zásadně odlišuje od tradičního mimetického a expresivního paradigmatu. Za pomoci úvah Gilese Deleuze Gil dokazuje, že i v případě tance zbaveného schopnosti reprezentovat a vyjadřovat emocionální obsahy můžeme hovořit o jednotkách tance, o jejich významu a jednotě, tedy o jazyku tance. Tuto myšlenku Gil upřesňuje pomocí paralely mezi tancem v Cunninghamově pojetí a moderním malířstvím.

- Description:
- The aim of this paper is to present the results of an investigation of induced seismic events which occurred during mining in the coalfields of Plants Paskov and Staříč of the Paskov Mine which belong to the southern part of the Ostrava-Karviná coal mines. Some results obtained in the time period January 1992 - December 2002 have already been published, and therefore, are mentioned here only briefly. The paper is based on new results of seismological observations at the OKC, KLOK, STEB seismic stations operated by the Institute of Geonics AS CR and stations of the Green Gas DPB, a.s., Paskov. A total of 26 seismic events were monitored from January 2008 to February 2012, most of them were localized into the area under study. As for the energy span of individual events according to the energetic classification of the Geophysical Centre of the Green Gas DPB, a.s., Paskov, all seismic events in Table 1 were estimated within the limits E(J) <5.0 ×102 ÷ 2.0 × 104>., Karel Holub, Jana Rušajová and Josef Holečko., and Obsahuje bibliografii

- Description:
- Jako dobový dokument zde nejdříve přinášíme podstatné části Šafránkova vlastního životopisu, jež vydal vlastním nákladem v roce 1936. Tato, dnes naprosto běžná sebeprezentace vyvolala u starší generace univerzitních fyziků podrážděnou reakci. Důkaz o tom nalezeneme v příslušné (zde rovněž přetištěné) autobiografie Vladimíra Nováka. Je velmi pravděpodobné, že Novák na Šafránka přenesl svou averzi k některým fyzikům starší generace, jmenovitě profesorům Felixovi a Posejpalovi. Třetím dokumentem je ukázka z knihy právě vydané nakladatelstvím Academia, v niž autorka líčí události provázející Šafránkovy přednášky ve Společnosti pro šíření vědeckých a politických znalostí v padesátých letech., Jaroslav Šafránek ; úvod redakce společný dalším dvěma článkům je uveden na straně 318., and Části Šafránkova vlastního životopisu [Curriculum vitae. Vlastním nákladem, Praha 1935, s. 5-8, 13-28]
