    Soil samples were collected from the feet of Marsh Warblers Acrocephalus palustris and Reed Warblers Acrocephalus scirpaceus caught soon after crossing the Sudan Red Sea coast of Africa. We measured carbon  (δ13Csoil_feet) and deuterium (δDsoil_feet) isotope ratios in these soils with the objective of identifying possible take-off sites of these birds. We collected soils from three sites in the Caucasus region, a potential refuelingarea for the flight to Sudan, and from the Sudan Red sea coast, and compared their deuterium (δDsoil) with δDsoil_feet. There was a strong relationship between the arrival date of the birds and the isotope  signatures (δ13soil_feet and δDsoil_feet) of the soil they carried. Results suggest that warblers from different geographical regions or of differentage groups might use different staging sites before reaching the Sudan. Data for precipitation deuterium (äDprec) together with äDsoil and δDsoil_feet suggest that while early arriving birds had taken off from southeast Europe (picking up soil from this region), those arriving later had stopped off in Arabia. This indicates an intrinsic difference in strategy  between birds migrating at different times of the season. The isotopic compositions of biological tissues such as feathers have commonly been applied to track animal movement. But this is the first report of analysis of soil from birds’ feet: a novel approach to isotopic study based on material picked up and carried by an animal externally

    The study was conducted at Tselemti Woreda, Tigray region, Northern Ethiopia, some 1200 kms away from the capital, from November 2002 to April 2003. In the first phase of this study, questionnaire survey was carried out to assess livestock production constraints. Subsequently, a study on the occurrence of drug resistance to diminazene aceturate and isomethamidum chloride of Trypanosoma vivax isolate in artificially infected goats were conducted. Results of the questionnaire survey revealed that 95.7% of the interviewees replied that trypanosomosis is a series problem in their areas. Apart from this, under dosing of trypanocidal drugs appeared a common practice in the areas surveyed. Drug sensitivity test conducted on 18 artificially infected goats revealed that T. vivax developed resistance to the curative doses of diminazene aceturate (3.5 mg/kg b.wt) and isomethamidum chloride (0.25 mg/kg b.wt). No relapses were seen for those animals treated with diminazen aceturate at a dose of 7 mg/kg b.wt and 0.5 mg/kg b.wt of isomethamidum chloride. Sanative pair between diminazene aceturate and isometamidum chloride was also confirmed by the occurrence of no relapses after first treatment with diminazene aceturate (at 3.5 mg/kg) and isomethamidum chloride (0.25 mg/kg) and a second treatment with 0.25 mg/kg isomethamidum chloride and 3.5 mg/kg diminazene aceturate, respectively. During the 90 days of trial period there was no statistical significant difference (P>0.05) in mean PCV of the five groups before and after treatment: (26+1.23), (27.5+1.33), (26.5+2.03), (29.8+2.12) and (25.5+ 3.06) for groups I, II, III, IV and V respectively. Generally diminazene aceturate at dose of 7 mg/kg and isomethamidum chloride at dose of 0.5 mg/kg b.wt were most effective in terms of curing infections as well as improving PCV and body weight. It was concluded that where there are indications for drug resistance against isomethamidum and diminazene aceturate the use of trypanocidal drugs should be supervised, the principle of sanative pairs has to be applied and chemotherapy needs to be integrated with other methods like vector (tsetse and biting flies) control.

    The coolant mechanism of SBWR is similar with the Dodewaard Nuclear Power Plant (NPP) in the Netherlands that first went critical in 1968. The similarity of both NPP is cooled by natural convection system. These coolant concept is very related with same parameters on fuel bundle design especially fuel bundle length, core pressure drop and core flow rate as well as critical power bundle. The analysis was carried out by using COBRAG computer code. COBRAG computer code is GE Company proprietary. Basically COBRAG computer code is a tool to solve compressible three-dimensional, two fluid, three field equations for two phase flow. The three fields are the vapor field, the continuous liquid field, and the liquid drop field. This code has been applied to analyses model flow and heat transfer within the reactor core. This volume describes the finitevolume equations and the numerical solution methods used to solve these equations. This analysis of same parameters has been done i.e.; inlet sub cooling 20 BTU/lbm and 40 BTU/lbm, 1000 psi pressure and R-factor is 1.038, mass flux are 0.5 Mlb/hr.ft2, 0.75 Mlb/hr.ft2, 1.00 Mlb/hr.ft2 and 1.25 Mlb/hr.ft2. Those conditions based on history operation of some type of the cell fuel bundle line at GE Nuclear Energy. According to the results, it can be concluded that SBWR critical power bundle is 10.5 % less than current BWR critical power bundle with length reduction of 12 ft to 9 ft

    Spring weights of some Palaearctic passerines in Ethiopia and Kenya: evidence for important migration staging areas in eastern Ethiopia

    Palaearctic migrants were trapped in late April and early May at a passage site near Jijiga in eastern Ethiopia. Willow Warblers Phylloscopus trochilus and Spotted Flycatchers Muscicapa striata were predominant, while Red-backed Shrikes Lanius collurio, Sedge Warblers Acrocephalus schoenobaenus, Reed Warblers A. scirpaceus, Garden Warblers Sylvia borin and Common Whitethroats S. communis also featured prominently. Weights were high in all species, and over 70% of the birds caught were extremely fat. Spring weights and fat scores at Jijiga were compared with those found in the same species in Kenya, and the difference was striking. In Kenya, most species had mean spring weights 10–20% above lean weight; at Jijiga, species’ mean weights ranged from 30% to 55% above lean weight. Whereas the reserves of most migrants departing from Kenya would have supported flights only as far as Ethiopia, the fat loads of birds at Jijiga indicated a potential for crossing Arabia with little need to feed. This suggests important staging and fattening grounds between these two areas, perhaps in the Acacia–Commiphora bushlands drained by the upper Juba and Shebelle rivers and their tributaries

    Perancangan Resor di Kampar Kiri Hulu dengan Pendekatan Arsitektur Posmodern

    Full text link
    Tanjung Belit village in Kampar Kiri Hulu subdistrict has been transformed to be tourism object and it is passed through by a river (Sebayang River). This place does not provide adequatefacility for accommodation. That is the reason why there has to be a temporary accommodation, such as resort. Buildings with the characteristics of rumah lontiok still stand in this region.However, the villagers had not used those characteristics. The villagers focus more on maximizing the function of the shapes and space of their house. To reflect characteristics of the place where the resort is built, Postmodern Architecture is the suitable theme for this resort design. By using Postmodern Architecture topic as design approach, hence we get the Compound of Composure andGregarious concept. Composure is interpreted as modern architeture which emphasizes on function and simple form, and Gregarious is interpreted as Lontiok Architecture which has more shapes and carved objects. The compatibility of the concept is applied on site pattern and building form including zoning, mass order, outdoor planning, mass formation, indoor planning, and interior

    On Active Surge Control of Compression Systems Via Characteristic Linearization and Model Nonlinearity Cancellation

    Get PDF
    A simple approach of active surge control of compression systems is presented. Specifically, nonlinear components of the pressure ratio and rotating speed states of the Moore-Greitzer model are transferred into the input vectors. Subsequently, the compressor characteristic is linearized into two modes, which describe the stable region and the unstable region respectively. As a result, the system\u27s state and input matrices both appear linear, to which linear realization and analysis are applicable. A linear quadratic regulator plus integrator is then chosen as closed-loop controller. By simulation it was shown that the modified model and characteristics can describe surge behavior, while the closed-loop controller can stabilize the system in the unstable operating region. The last-mentioned was achieved when massflow was 5.38 per cent less than the surge point
