Selecting an appropriate size domestic rainwater tank for Colombo
No full textBoth India and Sri Lanka have experienced rapid population growth and migration to the major cities in the past decade. This rapid urbanisation has resulted in overstressing of existing water supply systems, with a loss of recharge areas and an increased depletion of groundwater. These effects have further aggravated the urban water crisis. During the monsoons, the existing drainage systems are overloaded and overflow thereby resulting in flooding causing severe damage to property. Sewage overflows often lead to the outbreak of epidemics and occasionally to the loss of life. Rainwater harvesting systems serve the dual purpose of water storage to reduce urban runoff peak flows as well as augmentation of the existing water supply systems. To achieve minimum costs while optimising the security of supply, rainwater tanks need to be sized taking the local rainfall conditions into consideration. This paper presents a methodology to determine the optimal size of rooftop storage based on historical rainfall data. Annual savings of in-house demand as well as the security of rainwater supply are discussed. The methodology is applied to Colombo in Sri Lanka. A case study is based on 150lpd household demand with 25m2 of roof area in Colombo. The appropriate rainwater tank is determined to be 2000 L in capacity. The resulting water saving is 54% of annual in-house demand and more importantly, zero supply from the tank happens during only one third of the year

LA FEDE È E SI FA CULTURA: LA PROPOSTA AMBROSIANA DEL CARD. GIOVANNI COLOMBO E DELLA CHIESA MILANESE
No full textLa riforma del rito ambrosiano e le’dizione bilingue dell’Opera omnia di sant’Ambrogio sono atti magisteriali e pastorali, ma anche due tra i più importanti atti culturali della storia recente di Milano e d’Italia, perché hanno plasmato l’identità della società milanese nei difficili anni dell’immigrazione e, ancora oggi, contribuiscono a caratterizzare la personalità di Milano, rendendola capace di coniugare nel presente tradizione e innovazione.
Da questo contesto storico si evince la fecondità del metodo della fede, che è e si fa cultura.The reform of the Ambrosian rite and the bilingual edition of Ambrogio’s Opera Omnia not only are magisterial and pastoral deeds, but are also among the most important cultural acts of recent Italy and Milan’s history. Together they shaped the identity of Milanese society in the hard times of immigration; today they still distinguish Milan’s character enabling the City to blend its traditions with innovation.
In such historical environment the “Faith method” shows its fertility by becoming and being itself cultur
Short Notes on Kinematic Analysis
No full textThis chapter presents a short overview on the main concepts related to the kinematic analysis of frame structures
Solution of Simple Reference Cases
No full textThis chapter presents the solution of simple reference cases of frame structures with the use of force method, displacement method or mixed method. The presented cases consider different loading condition (distributed loads, concentrated loads, thermal actions), different boundary conditions (rigid and/or elastic constraints), different geometrical configuration of frame and load (inclined rods, symmetrical and anti-symmetrical load and frame) and different mechanical behaviour of rods (elastic, axially deformable, infinitely rigid in bending)
Solution of Complex Frames
No full textThis chapter presents the solution of complex examples mixing the simple cases presented in the previous chapter. The worked examples are solved with the use of force method, displacement method and/or mixed method
Enzymic Acylation of Methyl D- and L-Glucopyranosides and 6-Deoxy-glucopyranosides
No full textMethyl 6-O-butyryl-alpha-D- and L-glucopyranosides and methyl 6-deoxy-alpha-D- and L-glucopyranosides have been submitted to lipase catalyzed butyrylation, using porcine pancreatic, Candida cylindracea, and Pseudomonas cepacia lipases in organic solvents. The influence of the orientation of the secondary hydroxyl groups on the regioselectivity of the butyrylation is discussed
Don Carlo Colombo e padre Agostino Gemelli: scienza, politica, teologia
No full textCarlo Colombo è stato un punto di riferimento per l’Università Cattolica sin dai tempi di padre Gemelli, che ha visto in lui una sorta di “coscienza” teologica cui l’ateneo poteva far riferimento. In Colombo il rettore scorgeva una sponda teologica sicura con cui rimediare alla mancanza di un contesto universitario capace di confrontare le acquisizioni teologiche con gli scottanti problemi della contemporaneità scientifica e sociopolitica. Tramite l’analisi di documentazione inedita e lo studio degli interventi del teologo di Venegono nelle pubblicazioni dell’Università Cattolica, il saggio permette di cogliere l’importanza di questa collaborazione, sinergica ad alcuni punti nodali della prospettiva ideologica di Gemelli e decisiva per divulgare l’interpretazione del magistero pontificio che era avallata dal gruppo direttivo dell’ateneo. Ne risultano nuovi acquisizioni anche su Carlo Colombo, nel suo affrancarsi da schemi ideologici e storiografici che sono inadeguati a spiegarne la figura. Si fa poi nuova luce sull’Istituto Giuseppe Toniolo di studi superiori, ente fondatore e finanziatore dell’Università Cattolica, sulla questione della Facoltà di Teologia, sull’apertura a sinistra e sui rapporti di Giovanni Battista Montini con l’ateneo milanese.Carlo Colombo has been a key figure for the Catholic University ever since Father Gemelli saw in him a theological conscience to which the University could refer. It was this conscience that, according to him, could lead the University in the confrontation with the most relevant contemporary scientific and socio-political issues. The importance of this collaboration is highlighted through the analysis of unpublished documentation and through the study of the theologian’s contributions to the University’s publications. This relevance was further reinforced by the synergy with Gemelli’s ideological perspective. Furthermore, the partnership with Colombo was decisive in order to divulge the Directive Board’s interpretation of Pontifical teaching. Through new acquisitions on Colombo’s figure, the essay reveals the inadequacy of ideological and historiographical schemas used to portray him in the past.
Finally the essay casts new light on the Giuseppe Toniolo Institute for Higher Education, the University’s founding and financing institution, as well as on some controversial issues such as the relations between Giovanni Battista Montini and the Milan campus
