far, no studies have been conducted to determine the serum concentration of manganese in dogs with babesiosis. Manganese (Mn) is neurotoxic when present in excessive concentrations ( Racette et al., 2017 ). The mechanism of neurotoxicity appears to be
Pure silica zeolite ZSM-5 has been synthesised in a slightly acidic aqueous fluoride medium which produces the protonated
form of the zeolite ZSM-5 . Tetrahalometallate  species of cobalt and manganese have been synthesised and increasing
mole fractions incorporated into the zeolite synthesis gel. The products have been analysed and characterised using simultaneous
thermogravimetric-derivative thermogravimetric analysis (TG-DTG). The thermal decomposition, under nitrogen of the associated
tetraethylammonium (TEA+) and tetrapropylammonium (TPA+) cations occluded within the zeolite channels is indicative and characteristic of the incorporation of the heteroatoms into
the zeolitic framework. Analysis by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray fluorescence (XRF),
and Fourier transform infrared spectroscopy (FTIR) has confirmed the reliability of thermogravimetric (TG) and derived thermogravimetric
analysis (DTG) as a diagnostic tool.
Keggin ion-pillared buserite was prepared by ion-exchanging the hexylammonium ion-expanded buserite with Keggin ions, [Al13O4(OH)24(H2O)12]7+. The starting material was synthetic Na-buserite, which is a layered manganese oxide of composition Na4Mn14O26xH2O. The thermal and redox properties of this oxide and its pillared derivative were compared in O2, N2 and H2 environments using TG, DSC and XRD. The results indicated an improvement in thermal stability of pillared compound relative
to Na-buserite in all gaseous environments. By using these compounds in catalysing the oxidation of ethane, it was found that
they were very active for complete oxidation.

The nuclide53Mn was produced by the following three nuclear reactions,52Cr(d, n)53Mn,51V(3He n)53Mn and50Cr(α, n), (α, p)53Mn. Enriched52Cr and50Cr metal targets were prepared on copper plate holder by electrodeposition. The commercially available natural vanadium foil
was used for the51V(3He, n)53Mn reaction. Each target was bombarded in a cyclotron. Manganese was extracted and purified without using carrier from the
bombarded targets by anion and cation exchanges and solvent extraction. The isotopic ratio53Mn/55Mn was measured by mass spectrometry and the amount of55Mn was determined by neutron activation analysis. The activity of53Mn obtained was 7 dpm by 750 millicoulombs in3He bombardment (E3He=20 MeV). The activity due to by-product54Mn was about several thousands times higher than that of53Mn in3He and deuteron bombardments, which were produced through51V(3He, γ)54Mn and53Cr(d, n)54Mn. In alpha bombardment (Eα=15 MeV), the activity of53Mn produced was 8 dpm by 95 millicoulombs. The activity ratio, dpm54Mn/dpm53Mn, was about 3, and this ratio was the best one among the results so far obtained.

Increased rates of P and K (monoammonium phosphate and potassium chloride) were applied in four replicates on two soils in spring 2001 as follows: a) standard fertilization (kg ha
: 177 N + 100 P
+ 150 K
O); b) a + 1500 kg P
; c) a + 1500 kg K
; d) = b + c. Residual effects of the fertilization were tested in the next year. Maize (OsSK552 hybrid) growing on Luzani soil resulted in 15% lower yield compared to the Kobas soil (7.75 and 9.06 t ha
, respectively). Mean the leaf (the ear-leaf at silking) concentrations (mg kg
) were 41.8 (Zn), 14.1 (Cu) and 131 (Fe), respectively. The leaf Mn was by 60% lower and the leaf Zn by 16% higher in 2002 compared to 2001. Maize grown in the Luzani trial had by 9% lower the leaf Zn, 10% lower the leaf Cu and by 37% higher the leaf Mn compared to the Kobas soil. Under the influence of P fertilization, the leaf Zn decreased by 37% compared to the control. Application of both P and K resulted in decreases of leaf Zn by 30%. However, P fertilization, alone or in combination with K, increased the leaf Mn for 111% and 72% respectively. Significant difference the leaf Cu (by 9% lower) was found under influences K fertilization only. The leaf Fe was independent on these factors.
