Abstract Angiostrongylus cantonensis has been found in Florida, USA, from the panhandle in the north to Miami and surrounding areas in the southern parts of the state, in both definitive and intermediate hosts in a limited studies completed in 2015. Additional studies have identified this parasite in a variety of intermediate hosts, both native and non-native gastropod species, with new host species recorded. Many areas in Florida with higher A. cantonensis prevalence were those with a high human population density, which suggests it is a matter of time before human infections occur in Florida. Case reports in the state currently involve non-human primates and include a gibbon and orangutan in Miami. Here, we report the current status of A. cantonensis in the state, as well as the infection in a capuchin monkey and presumptive infection in a red ruffed lemur in Gainesville, Florida.

Abstract Angiostrongylus cantonensis (rat lungworm) is a tropical and subtropical parasitic nematode, with infections in humans causing angiostrongyliasis (rat lungworm disease), characterized by eosinophilic meningitis. Hawaii has been identified as a global hotspot of infection, with recent reports of high infection rates in humans, as well as rat definitive and snail intermediate hosts. This study investigated variation in A. cantonensis infection, both prevalence and intensity, in wild populations of two species of rats (Rattus exulans and R. rattus) and one species of snail (Parmarion martensi). An overall infection prevalence of 86.2% was observed in P. martensi and 63.8% in rats, with R. exulans (77.4%) greater than R. rattus (47.6%). We found infections to vary with environmental and host-related factors. Body mass was a strong predictor of infection in all three species, with different patterns seen between sexes and species of rats. Infection prevalence and intensity for R. exulans were high in May 2018 and again in February 2019, but generally lower and more variable during the intervening months. Information on sources of variability of infection in wild host populations will be a crucial component in predicting the effectiveness of future disease surveillance or targeted management strategies.

Rat Lungworm

Like many pest and disease problems, rat lungworm has been slowly spreading around the world. First described by Chen from rats in China, the medical significance of this parasite was overlooked until 1944 when it was found infecting humans in Taiwan. Even then, because the report was published in Japanese, its importance remained largely unknown. In 1955, Mackerras and Sandars found this nematode among rats in Brisbane, Australia, and described its life cycle, including the importance of its molluscan intermediate hosts.

The Impact

Nghi Son is an economic zone oriented to developing heavy industry and petrochemicals and has potential to become the most substantial economic zone in the North Central region. The zone is also one of the potential waste sources polluting Thanh Hoa coastal waters. Numeric modeling using Delft3D software package with different scenarios: Current status scenario, controlled discharge scenario, and incident scenario was developed to simulate states of some pollutants of organics and nutrients from the zone to Thanh Hoa coastal waters in different periods. The simulation results show that under controlled discharge (increasing pollutant concentration with the control of waste discharge), the concentration of pollutants was increasing and high around discharging points. In contrast, in incident case from the zone, pollutant concentrations increase markedly both in the magnitude and in the impact range to surrounding areas. When an accident happens, the influence scale will be expanded significantly, especially in the rainy season.

Tellervotrema Gibson & Bray, 1982 (Digenea: Opecoelidae) was erected for Podocotyle-like species that possess asymmetrical pair of isolated groups of vitelline follicles in the posterior forebody, lack them dorsal to the caeca andparasitize archybenthal macrourid fishes. Tellervotrema armstrongi Gibson & Bray, 1982 is redescribed from the typehost, the common Atlantic grenadier, Nezumia aequalis (Günther), N. cyrano Marshall & Iwamoto, and from anunidentified macrourid collected from the northern Gulf of Mexico. Tellervotrema beringi (Mamaev, 1965) is redescribedfrom the giant grenadier, Albatrossia pectoralis (Gilbert), and Coryphaenoides sp. obtained from off Oregon. Thefollowing six features are suggested to distinguish T. armstrongi and T. beringi: egg size; position of the genital pore;posterior extent of the cirrus-sac relative to the ventral sucker; testes volume relative to hindbody size; anterior extent ofthe paired vitelline groups in the forebody; and geographic locality. The generic diagnosis of Tellervotrema is amended toinclude circumcaecal vitelline follicles, and the presence of the vitelline gap itself was found to be a more consistentdiagnostic generic character than the location of the resulting pair of distinct, isolated groups of vitelline follicles createdby the gap. A neotype and paraneotypes are designated for T. beringi. The following new host and locality records areestablished: first original report of T. armstrongi from N. cyrano; first report of a member of Tellervotrema from the giantgrenadier, A. pectoralis; and the waters off Oregon are a new locality record for Tellervotrema, a genus in the North PacificOcean known only from the Bering Sea and off Japan. A comprehensive listing of all parasites previously reported fromthe four macrourid species examined herein is given and intermediate hosts are postulated through which species of Tellervotrema may complete their life cycles in the deep.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.

Abstract In the article is analyzed own field data of the authors and scientific publications on the wintering of Anserinae in the Azov-Black Sea region of Ukraine in 1900–2017, but the main data was obtained in frame of international mid-winter counts (IWC) in 2005–2017. It was found that 9 species of Anserinae occur in this region during the different seasons of the year: Anser anser — nesting, wintering and migrating; Rufibrenta ruficollis, A. albifrons, A. erythropus, A. fabalis — migrating and wintering; Branta canadensis, Branta leucopsis, Branta bernicla, Chen caerulescens — vagrant or birds which flew away from captivity (zoo etc.). Eulabeia indica — is possible vagrant species. The most numerous wintering species is A. albifrons, common — Rufibrenta ruficollis, not numerous — Anser anser, the other species are not met annually and registered in a very small number. There was almost tenfold drop in number of wintering geese in the Azov-Black Sea region of Ukraine during the period of counts. The main reasons of such reducing of geese amount are the followwing: weather and climate conditions, changes in the forage acessibility, hunting and poaching pressure, poisoning as a result of deratization of agricultural lands, and from 2014 — the militarization of the Syvash area and stop of water supplying of Crimea through the North Crimean channell. It is likely that the factors mentioned above led to relocating of wintering areas of Anserinae, and resulted in decreasing of their amount in this region.

In het tweede deel van zijn bijdrage 1830: van de Belgische protonatie naar de natiestaat, over de gebeurtenissen van 1830-1831 als slotfase van een passage van de Belgische protonatie doorheen de grote politiek-maatschappelijke en culturele mutaties na de Franse Revolutie, ontwikkelt Lode Wils de stelling dat de periode 1829-1830 de "terminale crisis" vormde van het Koninkrijk der Verenigde Nederlanden. Terwijl koning Willem I definitief had laten verstaan dat hij de ministeriële verantwoordelijkheid definitief afwees en elke kritiek op het regime beschouwde als kritiek op de dynastie, groeide in het Zuiden de synergie in het verzet tussen klerikalen, liberalen en radicale anti-autoritaire groepen. In de vervreemding tussen het Noorden en het Zuiden en de uiteindelijke revolutionaire nationaal-liberale oppositie vanuit het Zuiden, speelde de taalproblematiek een minder belangrijke rol dan het klerikale element en de liberale aversie tegen het vorstelijk absolutisme van Willem I en de aangevoelde uitsluiting van de Belgen uit het openbaar ambt en vooral uit de leiding van de staat.________1830: from the Belgian pre-nation to the nation stateIn the second part of his contribution 1830: from the Belgian pre-nation to the nation state, dealing with the events from 1830-1831 as the concluding phase of a transition of the Belgian pre-nation through the major socio-political and cultural mutations after the French Revolution, Lode Wils develops the thesis that the period of 1829-1830 constituted the "terminal crisis" of the Kingdom of the United Netherlands. Whilst King William I had clearly given to understand that he definitively rejected ministerial responsibility and that he considered any criticism of the regime as a criticism of the dynasty, the synergy of resistance increased between the clericalists, liberals and radical anti-authoritarian groups in the South. In the alienation between the North and the South and the ultimate revolutionary national-liberal opposition from the South the language issue played a less important role than the clericalist element and the liberal aversion against the royal absolutism of William I and the sense of exclusion of the Belgians from public office and particularly from the government of the state.

The article assesses the state of the heat economy of the Northern region. The purpose of the article is to reveal the reasons for chronic backwardness of the region's industry from the average Russian indicators. To achieve the goal, solved the following problems: the features of heat economy in the North, analyzes the housing development, production and consumption of heat energy, as the sources of heat energy and heat networks, and also reforms in the heat economy of the region, based on which conclusions on assessment of the heat economy of the region. In recent years, there has been a twofold decrease in the rate of renewal of fixed assets of the heat economy against the norm, low rates of introduction of the resource-saving technologies in the heat economy, and in general, in the housing and communal services of the region. The level of marginal balance of supply and demand in the heat energy market is determined. The article is written to correct the decisions of the Federal and regional Executive authorities in terms of ensuring the reliability of heat economy of the Northern region.
