Studis on the climatological aspects of air pollution potential over trivandrum

The deteriorating air quality especially in urban environments is a cause of serious concern. In spite of being an effective sink, the atmosphere also has its own limitations in effectively dispersing the pollutants being dumped into it continuously by various sources, mainly industries. Many a time, it is not the higher emissions that cause alarming level of pollutants but the unfavourable atmospheric conditions under which the atmosphere is not able to disperse them effectively, leading to accumulation of pollutants near the ground. Hence, it is imperative to have an estimate of the atmospheric potential for dispersal of the substances emitted into it. This requires a knowledge of mixing height, ventilation coefficient, wind and stability of the region under study. Mere estimation of such pollution potential is not adequate, unless the probable distribution of concentration of pollutants is known. This can be obtained by means of mathematical models. The pollution potential coupled with the distribution of concentration provides a good basis for initiating steps to mitigate air pollution in any developing urban area. In this thesis, a fast developing industrial city, namely, Trivandrum is chosen for estimating the pollution potential and determining the spatial distribution of sulphur dioxide concentration. Each of the parameters required for pollution potential is discussed in detail separately. The thesis is divided into nine chapters.

Median Sets and Median Number of a Graph

A profile is a finite sequence of vertices of a graph. The set of all vertices of the graph which minimises the sum of the distances to the vertices of the profile is the median of the profile. Any subset of the vertex set such that it is the median of some profile is called a median set. The number of median sets of a graph is defined to be the median number of the graph. In this paper, we identify the median sets of various classes of graphs such as Kp − e, Kp,q forP > 2, and wheel graph and so forth. The median numbers of these graphs and hypercubes are found out, and an upper bound for the median number of even cycles is established.We also express the median number of a product graph in terms of the median number of their factors.

Mathematical Morphology on Hypergraphs Using Vertex-Hyperedge Correspondence

The focus of this paper is to develop computationally efficient mathematical morphology operators on hypergraphs. To this aim we consider lattice structures on hypergraphs on which we build morphological operators. We develop a pair of dual adjunctions between the vertex set and the hyperedge set of a hypergraph , by defining a vertex-hyperedge correspondence. This allows us to recover the classical notion of a dilation/erosion of a subset of vertices and to extend it to subhypergraphs of . This paper also studies the concept of morphological adjunction on hypergraphs for which both the input and the output are hypergraphs

Morphological filtering on hypergraphs

The focus of this article is to develop computationally efficient mathematical morphology operators on hypergraphs. To this aim we consider lattice structures on hypergraphs on which we build morphological operators. We develop a pair of dual adjunctions between the vertex set and the hyper edge set of a hypergraph H, by defining a vertex-hyperedge correspondence. This allows us to recover the classical notion of a dilation/erosion of a subset of vertices and to extend it to subhypergraphs of H. Afterward, we propose several new openings, closings, granulometries and alternate sequential filters acting (i) on the subsets of the vertex and hyperedge set of H and (ii) on the subhypergraphs of a hypergraph

On The Center Sets and Center Numbers of Some Graph Classes

For a set S of vertices and the vertex v in a connected graph G, max x2S d(x, v) is called the S-eccentricity of v in G. The set of vertices with minimum S-eccentricity is called the S-center of G. Any set A of vertices of G such that A is an S-center for some set S of vertices of G is called a center set. We identify the center sets of certain classes of graphs namely, Block graphs, Km,n, Kn −e, wheel graphs, odd cycles and symmetric even graphs and enumerate them for many of these graph classes. We also introduce the concept of center number which is defined as the number of distinct center sets of a graph and determine the center number of some graph classes

Fair Sets of Some Classes of Graphs

Given a non empty set S of vertices of a graph, the partiality of a vertex with respect to S is the di erence between maximum and minimum of the distances of the vertex to the vertices of S. The vertices with minimum partiality constitute the fair center of the set. Any vertex set which is the fair center of some set of vertices is called a fair set. In this paper we prove that the induced subgraph of any fair set is connected in the case of trees and characterise block graphs as the class of chordal graphs for which the induced subgraph of all fair sets are connected. The fair sets of Kn, Km;n, Kn e, wheel graphs, odd cycles and symmetric even graphs are identi ed. The fair sets of the Cartesian product graphs are also discussed

Die Wirkungen von Extensivierungs- und Vertragsnaturschutzprogrammen auf die Entwicklung einer "gerade noch aktuellen Agrarlandschaft"

Erfolgskontrollen für Agrarumweltprogramme bezogen sich bisher meistens auf einzelne Flächen oder auf programmbezogene, großräumige Evaluationen. Es wurde jedoch kaum untersucht, wie sich die Maßnahmen auf die Entwicklung einzelner Naturräume auswirken. Auch gab es keine Studien, welche die Wechselwirkungen zwischen den Beweggründen der Landnutzer auf der ei-nen- sowie Landnutzung und Vegetation auf der anderen Seite interpretierten. Die Dissertation Wirkungen von Extensivierungs- und Vertragsnaturschutzprogrammen auf die Entwick-lung einer »gerade noch aktuellen Agrarlandschaft« hat diese Lücke geschlossen. Sie erklärt, welche Bedeutung die hessischen Programme HELP und HEKUL für den hohen Anteil naturschutzfachlich wertvollen Grünlands im Rommeroder Hügel-land westlich des Meißner haben. Untersuchungsgegenstand waren die Grünlandvegetation und die landwirtschaftlichen Betriebe mit ihren Menschen und deren Beweggründen. Diese Inhalte er-forderten eine Vorgehensweise, die sowohl sozialwissenschaftliche als auch naturwissenschaftliche Methoden einbindet, um Bezüge zwischen Betrieben und Grünlandvegetation zu er-kennen. Umfangreiche pflanzensoziologische Untersuchungen und Interviews der Betriebsleiter waren Grundlage für eine Schlagdatenbank und weitergehende Auswertungen. Die Interpretation vegetationskundlicher Erhebungen im Kontext betrieblicher Entscheidungen und Beweggründe erforderte es, althergebrachte Ansätze in neuer Form zu verknüpfen. Die Bewertung der Programmwirkungen stützte sich auf die Schlagdatenbank und auf vier Szena-rien zur zukünftigen Gebietsentwicklung bei unterschiedlichen Programmfortschreibungen. Zur Darstellung von Erhebungen und Ergebnissen entstand eine Vielzahl thematischer Karten. Der überdurchschnittlich hohe Anteil naturschutzfachlich bedeutsamer Grünlandtypen auf den Programmflächen und die Interpretation der Szenarien belegten eine hohe Wirksamkeit von HELP und HEKUL im Gebiet. Nicht nur auf den Vertragsnaturschutzflächen des HELP, sondern auch auf dem HEKUL-Grünland sind naturschutzfachlich bedeutende Vegetationstypen überproportional vertreten. Die vier Szenarien ließen erkennen, dass eine Beschränkung des HELP auf Schutzgebiete, eine Abschaffung der HEKUL-Grünlandextensivierung oder gar eine ersatzlose Strei-chung beider Programme zu erheblichen Verschlechterungen der naturschutzfachlichen Situation führen würde. Gleichzeitig war festzustellen, dass es ohne die landwirtschaftlich schwierigen natur-räumlichen Verhältnisse sowie eine eher großteilige Agrarstruktur mit überdurchschnittlich flächen-starken und wirtschaftlich stabilen Vollerwerbsbetrieben keine so deutlichen Programmwirkungen gegeben hätte. Auch die Tatsache, dass viele Landwirte eine intensive Landwirtschaft aus innerer Überzeugung ablehnen und mit einer erheblich geringeren Stickstoffintensität wirtschaften als es HEKUL verlangt, wirkte verstärkend. Die große Bedeutung individueller Beweggründe einzelner Betriebsleiter wurde auch in den engen Beziehungen einzelner Grünland-Pflanzengesellschaften zu bestimmten Betriebstypen und sogar einzelnen Höfen sichtbar, deren Beschreibung und Interpretation wichtige Erkenntnisse zu den so-zioökonomischen Voraussetzungen verschiedener Vegetationstypen lieferte. Für die zukünftige Entwicklung der hessischen Agrarumweltförderung empfiehlt die Dissertation eine Einführung und bevorzugte Anwendung ergebnisorientierter Honorierungsverfahren, eine bessere Berücksichtigung des gering gedüngten Grünlands über eine differenzierte Förderung sehr extensiver Düngeregime, eine stärkere Modularisierung des Gesamtprogramms und eine Durchführung aller Maßnahmen im Vertragsverfahren. Die betriebszweigbezogene Grünlandextensivierung sollte zukünftig in Kulissen angeboten werden, in denen ein verstärktes Wechseln von Betrieben in die Mindestpflege nach DirektZahlVerpflV zu erwarten ist.

Heat stress response for physiological traits in dairy and dual purpose cattle populations on phenotypic and genetic scales

The main objective of this thesis was to determine the potential impact of heat stress (HS) on physiological traits of lactating cows and semen quality of bulls kept in a temperate climate. The thesis is comprised of three studies. An innovative statistical modeling aspect common to all three studies was the application of random regression methodology (RRM) to study the phenotypic and genetic trajectory of traits in dependency of a continuous temperature humidity index (THI). In the first study, semen quality and quantity traits of 562 Holstein sires kept on an AI station in northwestern Germany were analyzed in the course of THI calculated from data obtained from the nearest weather station. Heat stress was identified based on a decline in semen quality and quantity parameters. The identified general HS threshold (THI = 60) and the thermoneutal zone (THI in the range from 50 to 60) for semen production were lower than detected in studies conducted in tropical and subtropical climates. Even though adult bulls were characterized by higher semen productivity compared to younger bulls, they responded with a stronger semen production loss during harsh environments. Heritabilities (low to moderate range) and additive genetic variances of semen characteristics varied with different levels of THI. Also, based on genetic correlations genotype, by environment interactions were detected. Taken together, these findings suggest the application of specific selection strategies for specific climate conditions. In the second study, the effect of the continuous environmental descriptor THI as measured inside the barns on rectal temperatures (RT), skin temperatures (ST), vaginal temperatures (VT), respiration rates (RR), and pulse rate (PR) of lactating Holstein Friesian (HF) and dual-purpose German black pied cattle (DSN) was analyzed. Increasing HS from THI 65 (threshold) to THI 86 (maximal THI) resulted in an increase of RT by 0.6 °C (DSN) and 1 °C (HF), ST by 3.5 °C (HF) and 8 °C (DSN), VT by 0.3 °C (DSN), and RR by 47 breaths / minute (DSN), and decreased PR by 7 beats / minute (DSN). The undesired effects of rising THI on physiological traits were most pronounced for cows with high levels of milk yield and milk constituents, cows in early days in milk and later parities, and during summer seasons in the year 2014. In the third study of this dissertation, the genetic components of the cow’s physiological responses to HS were investigated. Heat stress was deduced from indoor THI measurements, and physiological traits were recorded on native DSN cows and their genetically upgraded crosses with Holstein Friesian sires in two experimental herds from pasture-based production systems reflecting a harsh environment of the northern part of Germany. Although heritabilities were in a low range (from 0.018 to 0.072), alterations of heritabilities, repeatabilities, and genetic components in the course of THI justify the implementation of genetic evaluations including heat stress components. However, low repeatabilities indicate the necessity of using repeated records for measuring physiological traits in German cattle. Moderate EBV correlations between different trait combinations indicate the potential of selection for one trait to simultaneously improve the other physiological attributes. In conclusion, bulls of AI centers and lactating cows suffer from HS during more extreme weather conditions also in the temperate climate of Northern Germany. Monitoring physiological traits during warm and humid conditions could provide precious information for detection of appropriate times for implementation of cooling systems and changes in feeding and management strategies. Subsequently, the inclusion of these physiological traits with THI specific breeding values into overall breeding goals could contribute to improving cattle adaptability by selecting the optimal animal for extreme hot and humid conditions. Furthermore, the recording of meteorological data in close distance to the cow and visualizing the surface body temperature by infrared thermography techniques might be helpful for recognizing heat tolerance and adaptability in cattle.
