Differential diagnosis Size and habitus very close to B. phaeax, differing from it by the colour of the metasoma and pattern of mesoscutal sculpture. The sculpture of the mesoscutum and the colour of the body suggest the Australian species Baeoneurella cf. nigra, but the shape of the fore wings (lanceolate vs rounded apically), the development of the postmarginal vein, the structure of the antenna and the sculpture of T2 clearly separate these two species. The colour of the body in B. maceki suggests B. mirabilis, but the pattern of mesoscutal sculpture clearly separates these two species. Distribution Palaearctic species (Figure 17d). Biology Unknown, but seems to be close to B. phaeax, both of them being present in the same samples and being relatively close in size and habitus. The maximum flight period is June – July, but specimens can be found in samples even to the end of August. Specimens from France (Gers, and Lot-et-Garonne) were aspirated in fields infested with Ischnodemus sabuleti (Fallen) (Blissidae) (Elias de Bree pers. comm.).

Type habitat and locality: Peat bog of Lucina natural reservation, Suceava District, North Moldavia, May 1972. Differential diagno.ri.r: Enchodelus lucinensis n. sp. comes closest to E. hopedoru. r (Thorne, 1929) Thorne, 1939, from which it differs by a more slender body, a shorter tail, a different number of supplements and vulva position; a shorter odontostyle with a longer aperture (1/ 10 in E. hopedorus); tail shorter than anal body diameter. The new species differs also from E. laevi.r Thorne, 1939 in having a more slender body and a shorter tail, a longer odontostyle (only one lip region in E. laevis), with a shorter aperture (1/4 odontostyle length in E. laevis). From E..rignyen. ri.r Loof, 1975 the new species is separated by a longer odontostyle, shorter aperture, tail, and the presence of vaginal sclerotization. By the form of the lip region (not angular) and fewer "saccate bodies" on tail, the new species can be distinguished from E. teres Thorne, 1939.Published as part of Popovici, Iuliana, 1978, New Nematode Species (Dorylaimoidea) From Romania, pp. 404-411 in Nematologica 24 (4) on pages 408-410, DOI: 10.1163/187529278X00533, http://zenodo.org/record/812265

Type habitat and locality: Type population collected in June, 1987 from a subalpine grassland on limestone, under Saxifraga moschata Wulf., at 1950-2000 m altitude, in the Retezatul Mic Mountains (Piatra Iorgovanului and Albele) (the Southern Carpathians), Romania. Type specimens: Holotype and two paratypes (female, male) on slides no. 49997 and 49998 deposited in the Collection of the Natural Historical Museum " Gr. Antipa " Bucharest, Romania. One female and one male in the Nematology Department, Agricultural University Wageningen, the Netherlands; two males at Rothamsted Experimental Station, Harpenden, England; other specimens deposited in the Department of Ecology, Biological Research Institute, Cluj-Napoca, Romania. Diagnosis: The species Enchodelus saxifragae sp. n. is distinguished by its long body, about 2 mm, lip region distinctly set off, lips rounded, odontostyle fairly long, 1.6-2 head-widths long, vulva pre-equatorial, tail short, smoothly rounded. Males have long spicules (56-70 pm) and 13-16 ventromedian supplements. Differential diagnosis: Enchodelus saxifragae sp. n. is close to E. distinctus Ahmad & Jairajpuri, 1980, E. hopedoroides Altherr, 1963 and E. ponorensis sp. n. by having lip region distinctly set off from body. It differs from E. distinctus by its longer body (L = 1.85 mm, only one female, in E. distinctus), longer odontostyle (37.5-40 pm vs 36 gm), lack of oesophago-intestinal disc (present in E. distinctus), vulva pre-equatorial vs post-equatorial, and by the presence of male (not found in E. distinctus). The new species differs from E. hopedoroides by its longer body (1.42-1.85 mm in E. hopedoroides), hemispheroidal lips (angular in E. hopedoroides), longer odontostyle (37.5-40 vs 33 J. 1 m) and odontophore (45-52.5 vs 43 pm) and by the presence of male (not found in E. hopedoroides). E. saxifragae sp. n. can be distinghuised from E. ponorensis sp. n. by its longer body (L = 2.03-2.35 mm vs L = 1.65-2.07 mm), odontostyle and odontophore (37.5-40 vs 23-25 Ujn, respectively 45-52.5 vs 32.5-37.5 J. 1 m), wider and more set off lip region, a more posterior position of fixed guiding ring (see Tables II and III) as well as shorter and smoothly rounded tail (25-32.5 vs 35-45 J. 1 m), and in the presence of male (absent in E. ponorensis sp. n.). Remarks: Enchodelus saxifragae sp. n. was found together with E. macrodorus (de Man, 1880) Thorne, 1939, but it could be easily distinguished from this cosmopolitan species by its longer body, distinctly set off lip region and males with more numerous ventromedian supplements.Published as part of Popovici, Iuliana, 1995, New Species Of Tubixaba And Enchodelus (Nematoda: Dorylaimida) From Romania, pp. 435-448 in Nematologica 41 on pages 442-445, DOI: 10.1163/003925995X00396, http://zenodo.org/record/812558

The species is distinguished by its medium size, odontostyle 20-23 gum long, shape of tail, presence of saccate bodies and males with numerous (22-28) regularly spaced ventromedian supplements. Differential diagnosis: Tubixaba saccata sp. n. is close to T. minima Botha & Heyns, 1990 and T. parva Pretorius, Kruger & Heyns, 1987 (Syn. T. tswanorum Nell & Heyns, 1987). It can be distinguished from T. minima by longer body (2.13-2.74 mm vs 1.72-2.12 mm), longer odontostyle (20-23 J. 1m vs 16.5-19 Jl.m) and tail (33-47.5 gum vs 23-31 1 pm),by the shape of tail and lack of male in T. minima. T. saccata sp. n. can be distinguished from T. parva by its shorter body size (2.13-2.74 mm vs 3.27-4.97 mm), longer odontostyle (20-23 pm vs 14-19 gum) and larger number of supplements (22-28 vs 14-19). From the type species, T. tuxaua Monteiro & Lordello, 1980, the new species can be separated very easily by smaller size ofbody, odontostyle and spicules (L = 9.44-11.66 mm, odontostyle 29-33 pm, spicules 195-206 pm in T. tuxaua), by thinner cuticle (4 J. 1 m vs 12-14 pm at midbody, 10-15 pm vs 18-20 gm on tail) and by larger number of supplements (22-28 vs 10- 13). Type locality and habitat: The type population, consisting of six females and 13 males, was collected in September, 1975 from an alluvial typic vermic soil (Pop & Postolache, 1987) of a montane grassland situated at 1000 m altitude, in the Poiana Ponor, Padis karstic region of the Bihor Mountains (Western Carpathians), Romania. Type specimens: Holotype female and one paratype male on slide no. 49994 deposited in the Collection of the Natural Historical Museum " Gr. Antipa ", Bucharest, Romania; two slides with two paratype females and respectively three paratype males in the Nematology Department, Agricultural University Wageningen, the Netherlands. Other paratypes deposited in the Department of Ecology, Biological Research Institute, Cluj-Napoca, Romania.Published as part of Popovici, Iuliana, 1995, New Species Of Tubixaba And Enchodelus (Nematoda: Dorylaimida) From Romania, pp. 435-448 in Nematologica 41 on pages 435-439, DOI: 10.1163/003925995X00396, http://zenodo.org/record/812558
The modernity of the research of Romanian astronomer Constantin Popovici
No full textWe present the model of the photogravitational field proposed by the romanian mathematician Constantin Popovici, basic equations. We give the variation of orbital energy in the photogravitational two bodies problem and energy integral. In this case the orbital energy is not conserved.The author is grateful to Dr. T. Oproiu for valuable comments which helped in improving the text
Liberalism and Conservatism in the Writings of Aurel C. Popovici
No full textIn our study we wanted to analyze how the Romanian political activist and ideologist Aurel C. Popovici (1863-1917) perceived liberalism and conservatism, two of the most important ideologies of the nineteenth century. For this purpose, we studied three of his main writings: Principiul de naţionalitate (The Nationality Principle), Statele Unite ale Austriei Mari (The United States of Great Austria) and Naţionalism sau democraţie: o critică a civilizaţiunii moderne (Nationalism or Democracy: a Critical Approach to Modern Civilization). We studied the way in which the renowned Banatian author perceived liberalism, but also the way he percieved several main principles of this ideology: the defense of liberty, the sovereignty of the people, representative government, the refusal of absolutism and pluralism. By analyzing these topics in Aurel C. Popovici’s writings, we identified several paradoxes of his thinking, which we tried to explain by appealing to other sources, like personal letters or memoirs belonging to friends or admirers.
Rezumat: În studiul nostru am dorit să analizăm modul în care activistul politic şi ideologul român Aurel C. Popovici (1863-1917) a perceput liberalismul şi conservatorismul, două dintre cele mai importante ideologii ale secolului al XIX-lea. Astfel, am studiat trei dintre principalele sale scrieri: Principiul de naţionalitate, Statele Unite ale Austriei Mari şi Naţionalism sau democraţie: o critică a civilizaţiilor moderne. Am studiat modul în care renumitul autor bănăţean a perceput liberalismul, dar şi modul în care a realizat mai multe principii importante ale acestei ideologii: apărarea libertăţii, suveranitatea poporului, guvernarea reprezentativă, refuzul absolutismului şi pluralismul. Analizând aceste subiecte în scrierile lui Aurel C. Popovici, am identificat mai multe paradoxuri ale gândirii sale, pe care am încercat să le explicăm apelând la alte surse, precum scrisori personale sau memorii aparţinând prietenilor sau admiratorilor.
