Life Cycle Impact Assessment applied to cactus pear crop production for generating bioenergy and biofertiliser

2020

Among the potential uses of cactus pear, the generation of bioenergy (biogas) and biofertiliser (digestate), from the Anaerobic Digestion (AD) of cladodes and fruits, is surveyed in this paper. Data for Life Cycle Impact Assessment (LCIA) was drawn from a farm located in Roccapalumba (Palermo, Sicily, Italy), where three cultivars were cultivated: 1) yellow pulp cultivar; 2) red pulp cultivar; 3) white pulp cultivar. LCIA was applied to six scenarios: 1) current dry crop; 2) current irrigated crop; 3) dry crop for fruit and bioenergy production; 4) irrigated crop for fruit and bioenergy production; 5) dry crop for bioenergy production; 6) irrigated crop for bioenergy production. According t…

Cactus pear (Opuntia ficus-indica) productivity, proximal composition and soil parameters as affected by planting time and agronomic management in a …

2021

Study of appropriate planting time and response to agronomic management practices is imperative for the newly introduced cactus pear (Opuntia ficus-indica (L.) Mill.) into a semi-arid region of India. Responses of cactus pear to agronomic practices (planting time and irrigation and fertilizer application) were evaluated to determine the potential for fodder production and livestock feed in a semi-arid environment of India. We assessed four planting times (February, March, July and October) and two agronomic managements (with and without irrigation and fertilizer application) during 2016–2020 at Jhansi, India. Cactus pear establishment and growth improved with planting time in July and Octob…

EVOLUTION OF ENDOGENOUS GIBERELLINS AT DIFFERENT STAGES OF FLOWERING IN RELATION TO RETURN BLOOM OF CACTUS PEAR (OPUNTIA FICUS-INDICA (L.) MILLER)

1998

Abstract The effect of flower emasculation, flower injection with paclobutrazol and the complete removal of the spring flush of flowers and cladodes on the changes in GA 3 concentration at different stages of bloom in flowers and fertile cladodes of Opuntia ficus-indica has been determined. Throughout the bloom period, the concentration of GA 3 was higher in intact flowers and the cladode than in flowers emasculated or injected with paclobutrazol. With the onset of blooming, GA 3 started to accumulate both in the flower and in the fertile cladode, and the highest concentration was measured at full bloom in the flower and in the cladodes whose flowers were not removed. Flower emasculation or…

Effect of surround WP (a Kaolin-based particle film) on Ceratitis capitata infestation, quality and postharvest behavior of cactus pear fruit cv Gial…

2021

ABSTRACT A Kaolin-particle film (Surround WP) was applied at 3% to cactus pear (Opuntia ficus-indica cv Gialla) to assess its capacity to Control medfly (Ceratitis capitata Wiedemann) infestation and to evaluate its effects on the quality and postharvest behavior of treated fruit. In the first trial, Kaolin was applied at the end of July when fruit were green and about two weeks later, at color breakage. Its efficacy was compared with a standard organophosphate insecticide (Phosmet). The experiment was conducted in two locations in 2014 and 2015. Kaolin application was very effective in preventing medfly attacks until natural fruit drop in November. Kaolin treated fruit were harvested at th…

Quality Perception and Consumer Choice of Cactus Pear: Results of Direct Survey in Italy

2015

Today, alongside the traditional search and experience quality attributes, credence attributes increasingly affect individual consumption. The aim of this paper is to identify and measure the principal attributes of quality in cactus pear and their effect on consumer choice. The hypothesis underlying the study is that credence attributes have a major influence on consumer choice compared to the other quality attributes. With this in mind a questionnaire was administered to 92 cactus pear consumers in Italy, and by means of an econometric model the relationship that single attributes have on the amount of cactus pear consumption was analysed. Results confirm that credence attributes are impo…

Recovery of colorants from red prickly pear peels and pulps enhanced by pulsed electric field and ultrasound

2016

Abstract The aim of this work was to evaluate the potential of the non-conventional pre-treatments; pulsed electric fields (PEFs) and ultrasounds (USNs), to enhance the extraction of red colorants from red prickly pear ( Opuntia stricta Haw.) peels and pulps. The overall goal was to valorize the thick part of the fruit, being discarded for fruit's consumption. PEF and USN treatments were first optimized using fruit slices, followed by a supplementary aqueous extraction (+ SAE) up to 1 h. The optimal conditions were then applied for peels and pulps, separately. Results showed that PEF + SAE and USN + SAE enhanced significantly the extraction of red colorants (betanin/isobetanin), compared to…

Observations on ant-plant interactions in Pachycentria and other genera of the Dissochaeteae (Melastomataceae) in Sabah and Sarawak

1998

Summary In Sabah and Sarawak (Malaysia) ant-plant interactions of Dissochaeteae were studied in the field. Whereas some species of Dissochaeteae show only loose and fortuitous interactions with ants as the result of the provision of pearl bodies and nesting places which are used by ants facultatively, Pachycentria constricta and P. glauca show a complex relationship with ants mediated by other ant plants. Both species provide pearl bodies and potential nesting space or shelter for ants in dried out and hollow root swellings. The main characteristic which differentiates them from all other Melastomataceae interacting with ants are their particular seeds which are attractive to ants and carri…

Background and Purpose In 2007, the WHO classification of brain tumors was extended by three new entities of glioneuronal tumors: papillary glioneuronal tumor (PGNT), rosette-forming glioneuronal tumor of the fourth ventricle (RGNT) and glioneuronal tumor with neuropil-like islands (GNTNI). Focusing on clinical characteristics and outcome, the authors performed a comprehensive individual patient data (IPD) meta-analysis of the cases reported in literature until December 2012.

‘Internationalizing Pearl Craigie’

2018

International audience; My presentation focuses on Pearl Craigie (aka John Oliver Hobbes), arguably a key figure of cosmopolitan fin de siècle. Born in the U.S. but educated in Britain and partly in France, Craigie became overnight famous with Some Emotions and a Moral in 1891 although the novella was published in Fisher T. Unwin’s Pseudonymous Series. In 1892 Craigie converted to Catholicism while embarking on a series of tales, plays, journalistic contributions including travelogues, and novels with a noted internationalistic vein. If her position within British Decadence is arguably debatable, her cosmopolitanism is not: from her personal networks to her literary writings including her j…

Subjective Assessment of Head and Facial Appearance in Children with Craniosynostoses after Surgical Treatment

2018

Background: Craniosynostoses are congenital defects in the construction of the skull involving premature fusion of one or more cranial sutures. Premature fusion of sutures causes characteristic skull deformation(s). This affect the structure and thus the appearance of the entire head and face. The aim of this study was to analyze parents&rsquo
