Goat kids carcasses fed with three milk replacers
Se evaluó y comparó las características
de carcasas de cabritos cruza Saanen y
Criollo alimentados durante 60 días con tres
sustitutos lácteos diferentes: sustituto formulado
en la unidad experimental FCA, sustituto
comercial para terneros COM y leche
de vaca LEC. Se evaluó la aceptación de la
carne obtenida por parte del consumidor de
Mendoza, Argentina, y la composición
acídica de las carcasas. Las diversas dietas
provocaron diferencias significativas
(p < 0.05) en el contenido de grasa intramuscular
de las carcasas: 8.08; 6.27 y
13.45 % respectivamente para FCA, COM y
LEC. También se encontraron diferencias
(p < 0.05) en la composición acídica, principalmente
en la proporción de ácido linoleico
(C18:0) en los cabritos FCA respecto de los
otros, resultado de la incorporación de una
alta proporción de aceites vegetales en su
fórmula. No obstante los distintos contenidos
grasos y composición acídica no hubo
diferencias significativas de aceptación por
parte del consumidor (p < 0.05).Carcasses characteristics of Criollo-
Saanen goat kids fed during 60 days with
three different milk replacers (goat kids
replacer developed by us FCA, comercial
replacer COM, and cow milk LEC), were
evaluated and compared. Meat acceptability
was tested and correlated with fat level and
fatty acid composition of carcasses.
Differences were detected in the amount of
intramuscular lipids (p < 0.05) for carcasses
of kid goats differently fed (8.08, 6.27 y
13.45 % for FCA, COM y LEC), and also in
fatty acid composition. FCA kid goats had
higher content of linoleic acid than the others,
as a result of the high proportion of vegetal
oils in this replacer. Although, these
differences in fat content and fatty acid
composition did not produce differences in
the acceptance of the meat (p < 0.05).Fil: Rebora, Cecilia.

Augmented Reality to Engage Visitors of Science Museums through Interactive Experiences
In the last years, interactive exhibitions based on digital technologies have become widely common, thanks to their flexibility and effectiveness in engaging visitors and creating memorable experiences. One of the topics in which digital technologies can be particularly effective is the communication of abstract concepts that are difficult for the human mind to imagine. An emblematic example is the astronomy discipline, which requires us to imagine and understand phenomena far away from our everyday life. In this paper, the authors present a research project, MARSS, in which digital technologies are used effectively to enhance the Users’ Experience of the Museo Astronomico di Brera located in Milan. Specifically, the MARSS project aims at designing and developing a new digital journey inside the museum to allow different categories of visitors to enjoy the exhibition in an engaging and interactive way. The paper presents the design and development phases of the experience and its evaluation with users. The results of the evaluation indicate that the digital interactive experience is appreciated by users and is successful in translating the content of high scientific value into more engaging and easily understandable elements
Il riallestimento del Museo Astronomico di Brera
Grazie a uno stanziamento della Regione Lombardia ottenuto tramite il bando “Progetti di valorizzazione e promozione di Istituti, Luoghi della cultura, siti UNESCO, itinerari culturali e di catalogazione del patrimonio culturale - ambito museo 2019” tra il maggio e il dicembre 2020 è stato realizzato il nuovo allestimento della galleria del MusAB.
Il MusAB ha in questa nuova esposizione l’ambizione di rispondere alla domanda “Cosa fa l’astronoma/o”? “Osservare, scoprire, misurare, rappresentare, sono queste le operazioni che compiono gli astronomi; noi cercheremo di illustrarle con l’aiuto degli antichi strumenti della Specola di Brera.” Così si legge nella rinnovata pannellistica del Museo mentre il telescopio Gualtieri, il Magnetometro, Boscovich e Napoleone ci guidano in prima persona alla scoperta di questa straordinaria disciplina. Van Gogh, Shakespeare, Tomasi di Lampedusa fanno da cornice alla visita e ci conducono fino a Marte dove il ricco patrimonio archivistico dell’INAF – Osservatorio Astronomico di Brera viene illustrato grazie alle riproduzioni digitali
Shelf-life prediction: A comparison of methods
The shelf-life assessment of a product is essential to ensuring its safety and integrity. Shelf life is the period of time during which the product retains its required quality level under well-defined storage conditions. To assess the stability of a generic product, a stability test is required: the product is kept under di↵erent storage conditions and the performance of characteris- tics used to assess the quality of the product is monitored. Data collected through stability tests are then used to predict the product’s shelf life under further storage conditions a applying the calculated degradation rate. Ki- netic models, such as the Arrhenius equation, are usually applied for this purpose. Since humidity can accelerate product degradation, it may be of interest to consider methods which quantify the e↵ect of humidity. This pa- per proposes a comparison of several methods used to predict shelf life: the Bracket method, Eyring method, Peck method, Klinger method and Q-rule. Two case studies are performed to compare the performance of the applied methods, in order to determine the most accurate method

Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy
IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical
attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced
colorectal cancers at diagnosis.
OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced
oncologic stage and change in clinical presentation for patients with colorectal cancer.
DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all
17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December
31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period),
in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was
30 days from surgery.
EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery,
palliative procedures, and atypical or segmental resections.
MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer
at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as
cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding,
lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery,
and palliative surgery. The independent association between the pandemic period and the outcomes
was assessed using multivariate random-effects logistic regression, with hospital as the cluster
variable.
RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years)
underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142
(56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was
significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR],
1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P < .001), and stenotic
lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03).
CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the
SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients
undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for
these patients
Extended reality in industry: past, present and future perspectives
The industry’s interest in Virtual and Augmented Reality (VR and AR) technologies started from the beginning of their appearance in the research world. Over the years, scholars observed ups and downs, to which various factors contributed. In recent years these technologies, now known as eXtended Reality (XR), have returned to fascinate the industrial world, mainly because most of the related enabling technologies have improved to the point of pushing companies to re-invest in them. The introduction
of approaches such as the digital twin one and the recent hype on the metaverse is also a push in this direction. A few questions arise: what are the benefits of such technologies in the industry today, and what are the unexplored possibilities? Starting from a systematic literature review and exploring the practical implications of integrating technologies in the industrial field, the paper tries to answer these questions. The paper is not intended as a technological forecast but as a stimulus for future research
Impact of multisensory XR technologies on museum exhibition visits
The use of digital technologies in museums is becoming increasingly popular, with a growing trend towards using multisensory eXtended Reality (XR) technologies to enhance visitor engagement and involvement. XR technologies like Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) have the potential to bring numerous advantages to museums, including increased accessibility and inclusivity. By allowing visitors to experience a sense of immersion and actively engage with cultural artifacts, XR technologies can improve emotional engagement and learning activities. However, the integration of these technologies is often related to temporary exhibitions, and there are concerns about the costs associated with implementation and the potential for technology to negatively impact the visitor experience. Despite these challenges, evaluating the impact of multisensory XR technologies on visitor experience is difficult. This paper outlines a laboratory-based research activity that compares the impact of traditional exhibitions and XR technologies on visitor experience and learning performance. The study simulates a museum exhibition and allows the user to interact with different paintings using different XR technologies in a controlled environment
