La ricerca analizza l’assetto delle necropoli romane di Aquileia, dal punto di vista dell’organizzazione spaziale, delle tipologie monumentali e della committenza delle tombe. Si prendono in considerazione le evidenze di carattere funerario di cui sia noto il luogo di provenienza. Si evince che i monumenti si disponevano lungo le sei strade principali in uscita dalla città, ma anche presso la viabilità secondaria a nord-est di Aquileia. In tutti i casi il tratto più vicino alle mura (entro 0,5-1 km) risulta il più ricco di testimonianze. La monumentalizzazione di questo settore va ascritta omogeneamente all’inizio dell’età imperiale, quando lo spazio viene occupato da ampi recinti con tombe erette in posizione di massima visibilità. A tale dinamica si accompagna una razionale divisione degli spazi lungo tutto il tracciato, disciplinata apparentemente con più rigore nella misura in agro, in particolare nel tratto più vicino alle mura. Si è notata la concentrazione di tombe monumentali in corrispondenza di ponti (necropoli della via Annia) e incroci stradali (necropoli nord-orientali). Monumenti di alto livello di età tardo-repubblicana e primo-imperiale (mausolei, edicole con statue) si sono osservati in località a circa 1-1,5 km dalla città lungo la viabilità nord- e sud-occidentale. Lo sfruttamento più intenso è riconoscibile nella necropoli lungo la strada verso la Pannonia, dove si registra un alto numero di altari funerari monumentali databili tra i primi decenni del I sec. d.C. e l’età traianea. I committenti sono soprattutto soldati e commercianti, che lungo questa direttrice svolgevano le loro attività professionali. Lo sfruttamento delle necropoli è diversificato nel tempo: quelle settentrionali mostrano una flessione delle testimonianze dopo i primi due decenni del II sec. d.C., mentre la via Annia (restaurata da Massimino il Trace) e la via meridionale (forse legata allo sviluppo di Grado) conservano abbondanti tracce di frequentazione fino al IV secolo, con numerose attestazioni di stele, ampiamente utilizzate fin dal I sec. d.C., oltre che di sarcofagi. / In this work we analyse the organisation of the Roman necropolis of Aquileia, by considering both topographical and monumental aspects. We consider spatial organisation of the sepulchral system, typology of the monuments, social status of the owners. Only attestations with a certified location are taken into account. The tombs are found to be positioned along the six main ways leading out from the city, but also along a secondary road, north-east from the city walls. All necropolis show a larger density of monuments within the first km from the city gates. The monumental development of these areas has to be ascribed to the beginning of the Imperial age. Wide sepulchral enclosures spread out in that period, with great tombs built up in a preminent and visible location. At the same time, most of space dedicated to burial purposes is partitioned in regular plots: near city walls this mainly concern the in agro dimension. A concentration of noteworthy monuments is observed in the vicinity of bridges (via Annia necropolis) and crossroads (north-eastern necropolis). Several aediculae and mausoleums of late Republican age and early Imperial age are found in areas at about 1-1,5 km from the city along north- and south-west ways. The largest number ot attentations is found in the necropolis along the road to Pannonia. Hence, we infer that this necropolis was the most exploitated one from the first decades of I century A.D. up to Trajan’s age. Great funerary altars with depictions at their sides are raised especially by soldiers and traders, whose professional activities gravitate around this road. Concerning the period of exploitation, we note differences between necropolis. The north- and north- eastern ones show a decrease of attestations after first two decades of II century A.D., maybe related to the changed political situation of the northern provinces. On the contrary, necropolis of via Annia (restored by Maximinus Thrax) and along southern ways (probably as consequence of the increasing importance of the neighboring town of Grado) appear to be used up to the beginning of IV century A.D. The most common types of monuments in this period are stelae (that were widely used in Aquileia from I century A.D.) and sarcophagi.

At various intervals there have appeared on the American scene unique individuals whose ideals and principles have shaped the course of American history and the destiny of the American people. More often than not, they have appeared, as if providentially, in times of stress and turmoil, or at the least, during periods that were particularly decisive to the nation's history.Such individuals have always had certain characteristics in common. They were men of integrity and principle. They had a deep and abiding love for their country and an unfaltering faith in her future under a democratic system of government. They were men of vision whose ideas were usually far ahead of the times in which they lived. And they were not content merely to espouse their particular principles in theory alone, they also had the necessary devotion to duty to work tirelessly to make those ideals a reality, and the courage and fortitude to remain constant in the face of the adversity which they encountered in the process. Most of them had an empathy for the common man which transcended the normal sphere of interpersonal relationships and elevated it to the plane which recognizes the human kinship and brotherhood of all men. And finally, all of them left a legacy of ideas which are universally viable, and which serve as a constant source for the renewal of those ideals which are the foundation and supporting strength of the nation.In the days when the Republic was new, America was fortunate in having more than a few men of this caliber--men like Thomas Jefferson, James Madison, Alexander Hamilton. And later, at decisive moments when the need was great, other men like Abraham Lincoln, Theodore Roosevelt, and Woodrow Wilson arose to lead their country and to plead the cause of liberalism and humanitarianism. Wendell Willkie was another such man. He believed in the integrity and worth of the individual, in his right to the basic human freedoms regardless of race, creed, or color, and in the ability of an enlightened citizenry to govern itself politically under a democratic system of government, and economically under the free-enterprise system.His contributions reflected these basic beliefs. At home he strove to lift American politics out of the realm of narrow, petty partisanship and expediency, and to elevate it to a system, regulated by high moral conduct, which would be responsive to the needs of the American people. In a broader sense, he fought imperialism both at home and abroad by working to establish those civil liberties which guarantee freedom, equal opportunity, and dignity to all human beings. He worked to rally the free world against the perils of a totalitarianism which threatened to destroy that freedom, and above all, to rally it in support of a system of international cooperation which not only would keep world peace, but also provide a forum where the brotherhood of man could become a reality.It is the purpose of this dissertation to examine the principles and ideals which guided Wendell Willkie's thinking and motivated his actions, to note the nineteenth-century background which fostered them, to follow the active crusade he made in their behalf, and finally, to summarize briefly the contribution of those ideals and principles to the American democratic system and to the concept of "one world."

En cette fin du XXe siècle où les faillites de l'environnement nous interpellent; alors que la diminution de la couche d'ozone, la pollution urbaine et la perturbation des conditions climatiques hypothèquent l'existence biologique de l'humanité, on parle de plus en plus de lois applicables à la gestion de l`environnement. Leur contexte appartient à des cadres spatiaux et juridiques qui se calquent sur les limites politiques, administratives des états et regroupements régionaux. Là où existent les lois sur la gestion de l'environnement, leur application intégrale n'est point garantie. De puissants groupes de pression et des influences politiques complaisants imposent volontiers un silence destructeur. On constate par ailleurs que l'approche qui inspire le pluralisme politique ainsi reconnu se voulant répressive, soulève des interrogations. Qu'est-ce que 'environnement et comment fonctionne-t-il? N'est-il pas important de reconsidérer le cadre théorique des rapports entre l'homme et l'environnement? Pourquoi parler de la gestion de l'environnement dans un contexte juridique? La loi Naturelle structure les géosystèmes environnementaux. Lorsqu'ils connaissent la moindre rupture d'équilibre, un processus de recherche de l'équilibre perdu se déclenche. Ainsi se comprend le principe de l'interpellation de la Terre, planète vivante, à l'endroit de l'humanité.

Cold-formed steel framing of residential and light commercial buildings continues to grow in popularity due to its structural and material advantages. The North American steel industry is actively performing research studies and developing design standards to assist in the cost-effectiveness of cold-formed steel in these markets. Cold-formed steel L-headers are structural components used over wall openings to transfer the loads to adjacent king studs. Recently, there has been an increased interest in L-headers among homebuilders primarily due to their ease of installation and low material cost. Design of the L-headers in North America is currently governed by the North American Standard for Cold Formed Steel Framing – Header Design, in combination with the North American Specification for Design of Cold Formed Steel Structural Members. However, the design provisions in the AISI - Header Design Standard are particularly limiting. For instance, the method for evaluation of span deflections for both single and double L-headers, and uplift flexural strength for single L-headers is currently not available primarily due to lack of research on the issues. Presented in this thesis are the findings from an extensive laboratory testing program of full-scale single and double cold-formed steel L-headers. The objective of the research was to investigate the structural behavior of L-headers under both gravity and uplift loads. From the analysis, improved ultimate flexural strength design expressions and new vertical deflection expressions for single and double L-header assemblies were developed. The concept of semi-rigid members was introduced to evaluate the flexural behavior and deflection performance of L-header assemblies.

Let K be the function field of an irreducible, smooth projective curve X defined over Fq. Let [lemniscate] be a fixed point on X and let A [a subset of or is equal to] K be the Dedekind domain of functions which are regular away from [lemniscate]. Following the work of Greg Anderson, we define special polynomials and explain how they are used to define an A-module (in the case where the class number of A and the degree of [lemniscate] are both one) known as the module of special points associated to the Drinfeld A-module [rho]. We show that this module is finitely generated and explicitly compute its rank. We also show that if K is a function field such that the degree of [lemniscate] is one, then the Goss L-function, evaluated at 1, is a finite linear combination of logarithms evaluated at algebraic points. We conclude with examples showing how to use special polynomials to compute special values of both the Goss L-function and the Goss zeta function.

ABSTRACT In this thesis, we investigate the amplification characteristics of gain-flattened L-band (1570-1600 nm) erbium-doped fiber amplifier (EDFA) by employing the 1480 nm bi-directional pumping configuration. L-Band EDFAs are attractive because the use of L-band and C-band (1530-1560 nm) EDFAs in parallel greatly expands the amplification wavelength region. We adjusted the length of erbium-doped fiber (EDF) to achieve the flat amplification characteristics in the 1573-1600 nm wavelength region without using gain equalizers. The L-band EDFA exhibited a signal gain of 23 dB with good uniformity (less than 1 dB) and a noise figure of 6.9 dB for a 1580 nm signal of 16-channel WDM system. We also used the simulation tools to investigate the characteristics of L-band EDFA with the same configuration. The simulation results quite agree with the experimental data.

Calophyllum inophyllum is a medicinal plant that is rich in bioactive natural products. Calophinone¡]29¡^¡Bcaloxanthone I¡]30¡^¡Bbrasilixanthone B¡]31¡^¡Bpyranojacareubin¡]32¡^ and osajaxanthone¡]33¡^are five compounds which were isolated from the bark in this experiment. It is the first time to isolate calophinone¡]29¡^ from a matural source. In order to identify calophinone¡]29¡^, 6-acetylcalophinone¡]34¡^ was prepared via acylation. All structures were determined primarily on the basis of 1D, 2D NMR¡BUV¡BIR and Mass spectral analyses. Besides, biological studies don¡¦t reveal that Calophinone¡]29¡^¡Bcaloxanthone I¡]30¡^¡Bbrasilixanthone B¡]31¡^¡Bpyranojacareubin¡]32¡^¡Bosajaxanthone¡]33¡^and 6-acetylcalophinone¡]34¡^, exhibited in vitro cytotoxicity against human liver carcunoma¡BHuman oral epidermoid carcunoma and Human cervical epidermoid carcunoma. In addition, four new Taxoid derivatives that were 13-O-camphanyl-7-O -nicotinoylbaccatin III¡]34¡^¡B13-O-camphanyl-1-deoxybaccatin VI¡]35¡^¡B13-O-¡]4-chlorobenzoyl¡^-7-O-nicotinoylbaccatin III¡]36¡^and 13-O-benzoyl-7-O -nicotinoylbaccatin III¡]37¡^have been prepared via esterification under sonication starting from 13-deacetyl-7-O-nicotinoylbaccatin III¡]32¡^ and 13-deacetyl-1-deoxybaccatin VI¡]31¡^. All the structures were established primarily on the basis of 1D and 2D NMR techniques including DEPT, COSY, HMBC experiments, as well as comparison with known related compounds. It was deemed quite promising to investigate the structure-activity relationship ( SAR ) for the C - 13 side chain analogues of Taxol with some modification of the baccatin III¡]30¡^ moiety in order to discover more effective anticancer agents with better pharmacological properties. Compounds 34 and 35 showed significant cytotoxicity against prostate cancer cell line¡]PC-3¡^. Under concentration of 10£gM, the cell survival percent was 76% and 65% in case of compounds 34 and 35 compared to 60 % in case of Taxol. According to the structure-activity relationship, nicotinoyl and camphanic acyl group should be the source of activity in compounds 30 and 31. Consequently, it is necessary to introduce nicotinoyl chloride and camphanic acyl chloride groups via chemical reaction to improve the bioactivity.
