    Notes:
    Field-grown spring wheat (Triticum aestivum L. cv. Dragon) was exposed to ambient and elevated CO2 concentrations (1.5 and 2 times ambient) in open-top chambers. Contents of non-structural carbohydrates were analysed enzymatically in leaves, stems and ears six times during the growing season. The impact of elevated CO2 on wheat carbohydrates was non-significant in most harvests. However, differences in the carbohydrate contents due to elevated CO2 were found in all plant compartments. Before anthesis, at growth stage (GS) 30 (the stem is 1 cm to the shoot apex), the plants grown in elevated CO2 contained significantly more water soluble carbohydrates (WSC), fructans, starch and total non-structural carbohydrates (TNC) in the leaves in comparison with the plants grown in ambient CO2. It is hypothesised that the plants from the treatments with elevated CO2 were sink-limited at GS30. After anthesis, the leaf WSC and TNC contents of the plants from elevated CO2 started to decline earlier than those of the plants from ambient CO2. This may indicate that the leaves of plants grown in the chambers with elevated CO2 senesced earlier. Elevated CO2 accelerated grain development: 2 weeks after anthesis, the plants grown in elevated CO2 contained significantly more starch and significantly less fructans in the ears compared to the plants grown in ambient CO2. Elevated CO2 had no effect on ear starch and TNC contents at the final harvest. Increasing the CO2 concentration from 360 to 520 μmol mol−1 had a larger effect on wheat non-structural carbohydrates than the further increase from 520 to 680 μmol mol−1. The results are discussed in relation to the effects of elevated CO2 on yield and yield components.

    Description / Table of Contents:
    Zusammenfassung Ägyptische Dattelkerne wurden thermisch untersucht, um die Möglickkeit einer Verwendung als Quellen für wertvolle Verbindungen zu ergründen. Außerdem wurden technische Daten ermittelt, die zur Festlegung der Optimumtemperatur für die Gestaltung und den Betrieb der Geräte zur pyrolytischen Behandlung von Dattelkernen benötigt werden. Es wurden zwei Versuchsreihen durchgeführt, bei denen einerseits Thermogravimetrie (TG) und andererseits Differentialthermoanalyse (DTA) Anwendung fand. Die TG Ergebnisse eröffnen eine rein kinetisch kontrollierte Reaktion erster Ordnung. Die Aktivierungsenergie und die Arrheniuskonstante betrugen 8,17 kJ/mol bzw. 0,0115 min−1. DTA Resultate gaben Auskunft über den Charakter und Reaktionsprodukte der Reaktionen bei der Pyrolyse.

    Резюме С целью оценки продук тов, как возможных источников полуения различных соединений, проведен термический анализ е гипетских финиковых косточек. П риведены также технические данные, н еобходимые для опред еления оптимальной темпера туры созданной пиролитической уста новки для обработки ф иниковых косточек. Проведено д ве различные серии экспериментов, включ ающих ТГ и ДТА. Результ аты ТГ показали чисто кинет ические контролируемую реак цию первого порядка. Э нергия активации и аррениус овская константа равнялись, соответст венно, 8,17 кдж-моль−1 и 0,0115 ми н−1. Результаты ДТА показ али характер реакций, про текающих в процессе п иролиза и соответствующие про дукты реакций.
    Notes:
    Abstract Thermal analyses was performed on Egyptian date kernels to assess the value of the products as possible sources of valuable compounds. It also furnished technical data necessary for determination of the optimum degree of temperature for the design and operation of units for the pyrolytic processing of date kernels. Two different sets of experiments were carried out, involving thermogravimetry (TG) and differential thermal analysis (DTA). The TG results revealed a purely kinetically controlled, first-order reaction. The activation energy and the Arrhenius constant were 8.17 kJ/mol and 0.0115 min−1, respectively. The DTA results indicated the nature of the reactions involved in the pyrolysis and the corresponding products.

    Description / Table of Contents:
    Résumé La parvaquone a été essayée pour le traitement de bovins infectés parTheileria annulata lorsqu'ils étaient présentés aux cliniques des environs de Bagdad. Sur plus de 200 cas présentés pour suspicion de theilériose entre juillet 1984 et juillet 1985, le médicament a été utilisé dans 45 cas où la theilériose était confirmée par l'examen microscopique du sang et de biopsies de ganglions lymphatiques, 27 cas étaient considérés comme des atteintes modérées et 18 comme des cas graves. Les poids des animaux étaient estimés à l'oeil et la parvaquone administrée par voie intra-musculaire à la dose normale de 20 mg/kg (soit 16 à 35 mg/kg). Un traitement unique à la parvaquone a été pratiqué dans 25 cas et il a du être renouvelé dans 20 cas mais il n'y avait pas corrélation entre la gravité des symptômes et le nombre de traitements requis. Dans 12 cas (27%) une thérapie antibactérienne a également été mise en oeuvre. Tous les malades étaient des animaux importés ou issus d'animaux importés et dans 64% des cas les animaux étaient âgés de moins de 6 mois. Les températures ont chuté immédiatement après le traitement et, pour la plupart, étaient normales (moins de 39°5) deux à trois jours après le traitement—sur 45 animaux traités, 43 ont guéri. Ces résultats apparaissent très favorables par rapport à la mortalité de 66% rapportée antérieurement et affectant les bovins non traités en Irak.
    Abstract:
    Resumen Se trató ganado infectado conTheileria annulata en forma natural con parvaquone, en clínicas veterinarias localizadas en la vecindad de Baghdad. De 200 casos admitidos con sospecha de theileriosis, entre julio 1984 y julio 1985, la droga se usó en 45 casos confirmados mediante el examen microscópico de frotis de sangre y biopsias de ganglios linfáticos. Veintisiete de los casos se consideraron moderados y 18 casos severos. Se estimaron los pesos de los animales enfermos, suministrandoles parvaquone vía intramuscular en dosis nominales de 20 mg/kg (rango 16–35 mg/kg). Se utilizó un solo tratamiento con parvaquone en 25 casos clínicos, mediante la aplicación de una sola inyección y se aplicaron dos inyecciones en 20 casos (doble tratamiento), sin que se encontrara correlación alguna entre la severidad de la enfermedad, recuperación y número de tratamientos. Doce casos (27%) recibieron también algún tratamiento antibacteriano. Todos los casos de theileriosis se presentaron en ganado exótico o nacido de ganado exótico (importado) y 64% de los casos ocurrieron en ganado bajo los seis meses de edad. La temperatura bajó inmediatamente después del tratamiento, normalizándose dos o tres días después de tratamiento (bajo 39.5°C). De los 45 casos tratados 43 se recuperaron. Se informa una mortalidad previa de 60% en ganado importado no tratado contra theileriosis en Iraq.
    Notes:
    Summary Parvaquone was tested in cattle infected withTheileria annulata when they were presented at clinics in the vicinity of Baghdad. Out of over 200 cases presented with suspected theileriosis between July 1984 and July 1985, the drug was used in 45 cases where theileriosis was confirmed by microscopic examination of blood and lymph node biopsy smears. Twenty seven of the cases were considered mild and 18 cases severe. Weights of the cattle were estimated and parvaquone was administered by intramuscular injection at a nominal dose of 20 mg/kg. A single treatment with parvaquone was used in 25 cases and 20 cases were treated twice but there was no correlation between severity of disease and the number of treatments given. Twelve cases (27%) also received antibacterial therapy. All cases were in exotic cattle or cattle born from exotic (imported) cattle and 64% of the cases were in cattle under six months of age. Temperatures dropped immediately after treatment and the majority were normal (below 39.5°C) by two to three days after the first treatment. Of the 45 cases treated 43 recovered. This compares very favourably with a previously reported mortality of 66% in untreated imported cattle in Iraq.
