Stringy E-functions of hypersurfaces and of Brieskorn singularities

We show that for a hypersurface Batyrev's stringy E-function can be seen as a residue of the Hodge zeta function, a specialization of the motivic zeta function of Denef and Loeser. This is a nice application of inversion of adjunction. If an affine hypersurface is given by a polynomial that is non-degenerate with respect to its Newton polyhedron, then the motivic zeta function and thus the stringy E-function can be computed from this Newton polyhedron (by work of Artal, Cassou-Nogues, Luengo and Melle based on an algorithm of Denef and Hoornaert). We use this procedure to obtain an easy way to compute the contribution of a Brieskorn singularity to the stringy E-function. As a corollary, we prove that stringy Hodge numbers of varieties with a certain class of strictly canonical Brieskorn singularities are nonnegative. We conclude by computing an interesting 6-dimensional example. It shows that a result, implying nonnegativity of stringy Hodge numbers in lower dimensional cases, obtained in our previous paper, is not true in higher dimension.Comment: 21 page

Experimental control strategies reducing the fungicide input at a practical scale

Phytophthora infestans is the most devastating disease in potato cultivation. Chemical control is necessary to ensure a healthy crop. At the same time Dutch governmental policy asks for a reduction of the environmental impact of potato late blight control by 75% in 2012 as compared to 1996-1998. The aim of the experiments was to compare Decision Support Systems with different approaches to blight risk management for their ability to reduce the fungicide input without compromising control efficacy. Considerable savings, up to 81% when compared to weekly, full dose rate, spray schedules, can be achieved by using information on cultivar resistance, length of the critical period and disease pressure to decide whether or not to spray. The subroutine calculating the potential for viable transport of spores is only effective on resistant varieties as the threshold was exceeded with every critical period on less resistant cultivars. Implications of the experimental control strategies for agricultural practise are discusse

Inventarisatie omstandigheden optreden zwarte vlekken in peen : analyse praktijkmonsters 2008

De gegevens van het teeltjaar 2008 zijn in opdracht van het Productschap Tuinbouw geanalyseerd. Agrifirm heeft een lijst van teeltgegevens van peen partijen van hun klanten verzameld en bij het uitschuren de peen beoordeeld op ziekte. PPO-AGV heeft de schimmels gedetermineerd en een analyse van de teeltgegevens uitgevoerd

Het klieven van de buigpees bij ulcera van de tenen

Meer dan 25% van alle diabetische voetproblemen wordt veroorzaakt door ulcera. De genezingskans met een conservatief beleid is laag, waarbij ruim tweederde van de ulcera na twintig weken nog niet genezen is. Ondanks dat de recidiefkans en de amputatiekans afnemen bij een multidisciplinaire aanpak van diabetische voetulcera, worden voor beiden nog percentages van boven de 80% gerapporteerd. Meer dan 50% van alle diabetische voetulcera bevindt zich ter hoogte van de tenen. Bij een groot deel hiervan ligt een anatomische standsafwijking (klauw- of hamerteen) aan ten grondsla

Rate of information processing and reaction time of aircraft pilots and non-pilots.

Reaction time and rate of information processing are cited as critical components in the make-up of pilots. A need was identified to establish the validity of various chronometric measures in the selection of pilots. Fifty-eight military and commercial pilots and twenty non-pilots were subjected to Schepers’ Computerised Information Processing Test Battery, which measures reaction time, form discrimination time, colour discrimination time, rate of information processing(perceptual) and rate of information processing (conceptual). Five hypotheses and one postulate were formulated and tested. The results indicate that pilots could be differentiated from non-pilots with 92,3% accuracy. However, the results need to be cross-validated before they are used for selection

Minutes of the Classis of Holland

Albertus C. Van Raalte informed the Classis of Holland on April 29, 1852, that he had received a letter from the Rev. J. J. Schepers written on February 18 which requests that the Classis install Schepers as pastor of the congregation. However, the congregation does not promise to unite with the Albany denomination. But Van Raalte and the Classis feel that this congregation had no right to leave the congregation in Graafschap and without authorization appointed Schepers as pastor.https://digitalcommons.hope.edu/vrp_1850s/1223/thumbnail.jp
