Critically narrating some impacts on the civitas and urbs of the pandemic, the paper argues how the relative pathos of death and poverty unleashed on Milan is, in fact, a contingency on the endless flux of the urban body in the long history of the city. The text, divided into five paragraphs - then (May 2019), yesterday (March 2020), today (April 2020), tomorrow (May 2020) and later (May 2030) -, in addition to the bibliography, develops as in a Gaussian curve, the two extremes being (“then” and “later”) in points before and after the beginning of the curvature, respectively (i.e., describing situations “at full throttle”), the centre (“today”) the peak of the curve and the two intermediates (“yesterday” and “tomorrow”) in its ascending and descending sections, respectively. The style varies from calmness at the extremes (with mainly hypotactic periods) to the unease of the intermediates, namely, at its peak (with mainly paratactic periods)., TeMA - Journal of Land Use, Mobility and Environment, 2020: Special Issue.

Herbicides classified as synthetic auxins have been most commonly used to control broadleaf weeds in a variety of crops and in non-cropland areas since the first synthetic auxin herbicide (SAH), 2,4-D, was introduced to the market in the mid-1940s. The incidence of weed species resistant to SAHs is relatively low considering their long-term global application with 29 broadleaf weed species confirmed resistant to date. An understanding of the context and mechanisms of SAH resistance evolution can inform management practices to sustain the longevity and utility of this important class of herbicides. A symposium was convened during the 2nd Global Herbicide Resistance Challenge (May 2017 in Denver, CO, USA) to provide an overview of the current state of knowledge of SAH resistance mechanisms including case studies of weed species resistant to SAHs and perspectives on mitigating resistance development in SAH-tolerant crops. The authors are arrayed in alphabetical order because each made substantive contributions to the success of the Weed Resistance to Synthetic Auxin Herbicides symposium convened on May 15, 2017 during the Global Herbicide Resistance Challenge meeting in Denver, Colorado,USA. The symposium organizers and speakerswould like to thank the Global Herbicide Resistance Committee (www .hracglobal.com) for their financial support that made the symposium possible.

Nella scuola bresciana di urbanistica da più di un ventennio l’attenzione scientifica è incentrata sull’elevazione della qualità della vita, cui sono primariamente riconducibili sia le tematiche ambientali che quelle della sicurezza orientata alla socialità. Il trinomio ambiente, sicurezza e società induce a riflettere sulla ricchezza e centralità del concetto di luogo. A tal fine il dottore di ricerca in “Luoghi e tempi della città e del territorio” ha acquisito una formazione e una competenza nella progettazione architettonica e urbana con approccio spazio-temporale e interdisciplinare, finalizzata a valutare la qualità urbana su una combinazione equilibrata di valori integrati, Territorio della Ricerca su Insediamenti e Ambiente.

The issue of the safety of mobility in the urban environment has been emerging as a primary social topic for some time now due to the number of casualties and, more generally, due to the impact on living conditions in the city. If correctly formulated, in fact, this subject has implications primarily and fundamentally with regard to the quality of urban life, as the citizen, and the vulnerable road user in particular, is severely restricted in their use of urban public paces. Consequently, an increasingly greater focus is being placed on acquiring methods, techniques and strategies for addressing the issue of planning, constructing and managing roads, squares and urban green spaces (and above all, applying the logic of reclaiming the historic and consolidated city) in order that the city can be used to its full potential by the citizen. The subject itself therefore presents an opportunity to re-establish urban planning regulations (and, more generally, city regulations) in accordance with the renewed interest in public spaces. The article discusses this matter and includes supporting elements and examples, also referring to the implications on the urban landscape., Tema.

As populações de plantas daninhas suscetíveis a um determinado herbicida são totalmente controladas quando a dose recomendada é corretamente aplicada. No entanto, há uma evolução contínua na sobrevivência e crescimento das plantas em resposta a baixas doses dos herbicidas como resultado da presença de características que podem causar um baixo nível de resistência a estes produtos. Estudos de seleção recorrente podem revelar se a variação fenotípica em resposta a uma dose baixa do herbicida é hereditária e pode conduzir à resistência ao herbicida. Estudos de seleção recorrente de plantas alógamas de Lolium rigidum sobreviventes baixas doses de herbicidas mostraram rápida evolução da resistência a herbicidas em apenas três gerações por intensificação progressiva de características de resistência a herbicidas inicialmente pouco relevantes. Em um estudo de campo, populações autógamas de Avena fatua foram submetidas a um processo de seleção recorrente resultante da aplicação de baixas doses do herbicida diclofop-methyl (inibidor da ACCase) ou o glyphosate (inibidor da EPSPS). As aplicações sucessivas de diclofop-methyl induziram o desenvolvimento de progênies distintas da população original em termos de resistência a este herbicida, com o aumento de duas vezes na LD50. As progênies selecionadas pelo uso de diclofop-methyl também mostraram-se mais resistentes a herbicidas inibidores da ALS indicando sugerindo a ocorrência de resistência cruzada. As aplicações sucessivas de glyphosate não induziram a formação de progênies mais resistentes. A capacidade da A. fatua para responder à pressão de seleção imposta por baixas doses de herbicidas é limitada e muito mais baixa ... Herbicides when applied at the correct stage and dose are highly toxic to plants. Herbicide-susceptible weed populations are completely controlled at the recommended herbicide label dose. However, there is continuous variation in plant survival and growth in response to herbicide low doses (below-label) because specific plant traits can confer some low level resistance. Recurrent (directional) selection studies can reveal whether such a phenotypic variation in response to a herbicide low dose is heritable and can lead to herbicide resistance. Recurrent selection studies with allogamous cross-pollinated Lolium rigidum plants surviving at a low herbicide dose showed rapid evolution of herbicide resistance in three generations by progressive enrichment of minor herbicide resistance traits. In a common experimental garden study, we have subjected to low-dose recurrent selection a susceptible population of autogamous self-pollinated Avena fatua with the ACCase-inhibiting herbicide diclofop-methyl or the EPSPS-inhibiting glyphosate. Significant differences in response to selection between the selected progenies and parents were evident in the lines selected by low-dose diclofop-methyl, whereas glyphosate selection did not results in significant shifts. A two-fold diclofop resistance was quantified by comparison of estimated LD50 values and a significant increase in survival to ALS-inhibiting herbicides suggests cross-resistance. Importantly, the capacity of A. fatua to respond to low-dose herbicide selection is marginal and much lower than in L. rigidum. The dynamics of selection and the factors driving the evolution of resistance to herbicides in plants are discussed with particular emphasis on the implications of low-dose herbicide use weed management of autogamous self-pollinated vs allogamous cross ...
