Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
La maturazione delle mele: i processi che la caratterizzano e le metodiche di monitoraggio
No full textMele Red Delicious: la qualità dipende dalla conservazione
No full textDalla prova svolta su mele raccolte a Mezzolombardo nel 2018 si evidenzia che la combinazione dell’impiego di gas 1-Metilciclopropene (1-MCP) sulle mele raccolte e la DCA (Dynamic Controlled Atmosphere) in cella di conservazione consente di attendere qualche giorno in più nella raccolta, con importanti benefici in termini di qualità, senza compromettere la conservabilità del prodotto, e inoltre consente un allungamento della vita del prodotto, riducendo in modo evidente la presenza di riscaldo a fine conservazion
New scientific knowledge in kiwifruit storage using sanitization systems (Ionny®) avoiding postharvest chemical treatments
No full textLoss of produce during commercial kiwifruit storage is so high as to require the
adoption of specific techniques and preventive measures. Postharvest curing
techniques alone are not sufficient to guarantee valid economic results, particularly
when fruits are harvested in high-humidity environmental conditions due to rain or
heavy dew. The incidence of rot due to Botrytis spp. penetrating the pulp at the
detachment point of the stalk can reach high percentages (10-20% of damaged fruit),
and specific postharvest chemical treatment known as drenching is required. As
verified in the past, an alternative to the use of chemicals, with air sanitation of the
storage environment using an ionizer (Ionny®), is possible. Tests carried out during
the 2016-17 season have confirmed the validity of this technique in CA storage
conditions (-0.5/-0.7°C, RH>90%, CO2 3-4%, O2 2.5-3%, C2H4<0.02 ppm) alongside
curing, with results comparable to those obtained using the chemical treatment
fenhexamid in a drencher. A batch of ‘Hayward’ kiwifruit produced in the Trentino
(Italy) area was divided into three groups: 1) treatment with fenhexamid + curing +
CA; 2) curing + CA in an ionized environment; and 3) no treatment + curing + CA
(TEST). The trial found over 15% of fruits infected with Botrytis spp. in group 3, and
100% healthy fruits in groups 1 and 2. These results, as well as confirming the
outcome of previous trials, have also highlighted that group 2 (CA storage with air
sanitized by Ionny®) produced the best results (firmness, total acidity) both at the end
of storage and also after 8 d shelf-life at room temperatur
Effect of postharvest treatment on physiological disorders of new apple cultivars
No full textTraditional cultivars are still in demand, but growers are weeding them out in favor of cultivars with a better taste, crunchier texture and/or higher sales prices. The success of new cultivars will depend on its distinctiveness, on the consistence over years of quality, and on the growing, packing and marketing resources needed for their commercialization. New cultivars can offer an enhanced quality often coupled with unique attributes, however, less is known about their storage features and the influence of the storage protocols. The storability of new introduced cultivars is limited by physiological disorders naturally occurring during storage which seem to cause the main postharvest fruit losses. The present work focused on new promising apple cultivars developed in different countries and grown in the Trentino Alto Adige region (northern Italy). The trials were conducted in 2019 and 2020, during which a complex of different physiological disorders was observed, among which, soft scald represented the most common. The soft scald incidence was studied under different cooling protocols. The fast cooling determined a higher soft scald incidence on the tested cultivars, with a mean disease incidence ranging between 23.8 and 32.1% after storage with a highest value on cultivar ‘PRE03’. The two-step cooling allowed to reduce the incidence during short-term storage by more than four times. 1-methylcyclopropene (1-MCP) application showed a limited effect on soft scald incidenc
Effect of postharvest treatments on physiological disorders of ‘Galant’: a new scab resistant apple cultivar
No full textThe present work focuses on the promising scab resistant apple cultivar ‘Galant’ (Lumaga A 913) which shows great interest as a suitable cultivar for organic production but little is known about its postharvest storage. Experiments performed by the Fondazione Edmund Mach (FEM) from 2015 to 2017 show a complex of different physiological disorders affecting this apple: superficial scald, flesh browning, browning of the skin and underlying flesh (soft scald and soggy breakdown). Here, we present the results of different postharvest treatments applied in order to avoid fruit injury, including initial low oxygen stress conditions (ILOS) and 1-methylcyclopropene (1-MCP) application. Superficial scald symptoms commonly appeared on less mature fruits but the production of α-farnesene and its volatile oxidation products which are involved in the process are inhibited by using ILOS technology which kept the disorder under 4% disease incidence in comparison with controlled atmosphere (CA) with 35% after 180 d storage and 15 d shelf life. On the other hand, both ILOS and CA storage do not affect the incidence of internal browning and the incidence rates were always >60% after 14 d shelf-life. Based on the flesh browning disorders, the storability of ‘Galant’ was always limited to <180 d. The incidence of superficial scald and flesh browning were similar in both 1-MCP treated and untreated apple
Rehabilitation after wrist fracture: A narrative review of outcome measures and protocols
No full textINTRODUCTION: Wrist fractures represent the commonest fractures of upper limb. After the orthopedic surgical or conservative management, patients usually experience decrease of mobility, strength and function of wrist and hand, with consequent reduction of independence in daily life activities. For the management of the rehabilitative phase, a multitude of therapeutic approaches have been proposed, but a consensus on the program for rehabilitation of wrist fracture still lacks. Aim of this review was to describe the current literature evidence for rehabilitation after wrist fracture. EVIDENCE ACQUISITION: A search was performed using PubMed, Pedro and Scopus electronic databases for peer-reviewed literature related to rehabilitation of wrist fractures in adults published between January 2005 and April 2020. Only studies in English with participants older than 18 years were included and all types of study design were selected, except for systematic reviews, single case reports and congress proceedings. For each publication included, we reviewed the outcome measures and the rehabilitation program. EVIDENCE SYNTHESIS: We included 49 studies, reporting different rehabilitative protocols which integrate various approaches: advice, passive and active exercises, manual therapy and instrumental physiotherapy, sensorimotor and pharmacological interventions. We observed variability in terms of application (therapist-supervised versus self-administered home protocols), rehabilitation timing and outcome measures (objective measurement, evaluator-based scales, patient-reported outcome measures). CONCLUSIONS: After a wrist fracture, numerous rehabilitative approaches may be applied to reduce pain, enhance motility, increase strength and improve function of upper limb. On the basis of the current literature, we show a possible rehabilitative protocol after wrist fracture
