“I Wanna Be Your Dog” (The Stooges, 1969): Sottoculture giovanili, scoperta dell’erotismo e proto-punk
“I Wanna Be Your Dog” degli Stooges era un brano che già dal titolo proponeva una
provocazione esplicita e ammiccante. Questa canzone del 1969 omaggiava il boogie pianistico in una struttura molto più hard, radicale e graffiante, perfettamente in linea con le altre incisioni prodotte da una delle band più radicali e iconoclaste della storia del rock, cronologicamente in anticipo sulle sonorità selvagge della sottocultura punk.
“I Wanna Be Your Dog” è ancora oggi una canzone iconica nella sua evocazione cross-mediale.n
Household Consumption and Food Insecurity in Mexico: Covid19 and Sustainable Development
Attaining a lower level of food insecurity is crucial for developing countries as its consequences spread wide and deep into specific communities. Covid-19 has magnified the adverse effects of several problems worldwide, including food security. This study investigates the Mexican Households' four food security thresholds using the 2018 and 2020 waves of the National Household Income and Expenditure Survey (ENIGH), which contains the Latin American and Caribbean Food Security Scale (ELCSA). In this research, we assess the differences in the four food security categories with reference to both individual and household variables as well as contextual factors.2s

Influence of the ventilation strategy on the respiratory droplets dispersion inside a coach bus: CFD approach
The airborne transmission of the COVID-19 virus was considered the main cause of infection. The increasing concern about the virus spread in confined spaces, characterized by high crowding indexes and an often-inadequate air exchange system, pushes the scientific community to the design of many studies aimed at improving indoor air quality. The risk of transmission depends on several factors such as droplet properties, virus characteristics, and indoor airflow patterns. The main transmission route of the SARS-CoV-2 virus to humans is the respiratory route through small (<100 μm) and large droplets. In an indoor environment, the air exchange plays a fundamental role on the dispersion of the droplets. In this study, an integrated approach was developed to evaluate the influence of the ventilation strategy on the dispersion of respiratory droplets emitted inside a coach bus. There are no specific guidelines and standards on the air exchange rate (AER) values to be respected in indoor environments such as coach buses. The aim of this work is to analyse the influence of ventilation strategy on the respiratory droplet concentration and distribution emitted in a coach bus. Ansys FLUENT was used to numerically solve the well-known transient Navier-Stokes equations (URANS equations), the energy equation and using the Lagrangian Discrete Phase Model (DPM) approach to construct the droplet trajectories. The geometry is representative of an intercity bus, a vehicle constructed exclusively for the carriage of seated passengers. The 3D CAD model represented a coach bus with an HVAC system, within which an infected subject was present. The positions of exhaust vents and air-conditioning vents were chosen to ensure complete air circulation throughout the bus. The infected subject emitted droplets with a well-defined size distribution and mass through the mouth. The air exchange is provided in two different ways: general ventilation (from air intakes positioned along the bus windows and top side of central corridor) and personal ventilation (with air intakes for each passenger). For the general ventilation a single AER value was set (0.3 m3 s-1). The first results obtained showed a slight particle dispersion in the computational domain due to the airflow rate entered through the HVAC system, but a still elevated level of particle concentration tended to accumulate on the area near to infected subject. Additional analysis was executed to evaluate the beneficial effects linked to further addition of airflow through personal air-conditioning vents placed above every passenger's head. The results show the importance of the use of the ventilation system inside a coach bus, highlighting how the contribution linked to of the personal air exchange rate can lead to a significant reduction of droplet concentration exposure and consequently a reduction of the risk of infection from airborne diseases
Which tools are needed to implement Lean Production in an Industry 4.0 environment? A literature review
The Industry 4.0 revolution has been introduced for the first time in Germany in 2011 and, during last decade, it has introduced several technological innovations, such as novel information and communication systems in different business sectors, rising the attention of practitioners and scholars worldwide. Lean Production (LP) refers to a wide-ranging set process that improve mass production techniques to reduce cost, quality, reduce time to produce, and better react to market demands. The aim of this research study is to understand, through a comprehensive literature review, the relationship between LP practices and Industry 4.0 enabling technologies, as well as to understand which Industry 4.0 tools are currently implemented in LP by companies and main advantages derived from their use

Exogenous miRNAs from Moringa oleifera Lam. recover a dysregulated lipid metabolism
A balanced diet is critical for human health, and edible plants play an important role in providing essential micronutrients as well as specific microRNAs (miRNAs) that can regulate human gene expression. Here we present the effects of Moringa oleifera (MO) miRNAs (mol-miRs) on lipid metabolism. Through in silico studies we identified the potential genes involved in lipid metabolism targeted by mol-miRs. To this end, we tested the efficacy of an aqueous extract of MO seeds (MOES), as suggested in traditional African ethnomedicine, or its purified miRNAs. The biological properties of MO preparations were investigated using a human derived hepatoma cell line (HepG2) as a model. MOES treatment decreased intracellular lipid accumulation and induced apoptosis in HepG2. In the same cell line, transfection with mol-miRs showed similar effects to MOES. Moreover, the effect of the mol-miR pool was investigated in a pre-obese mouse model, in which treatment with mol-miRs was able to prevent dysregulation of lipid metabolism.1
