The objective of this study was twofold: first, to investigate how fermentation treatments influence the volatile composition across different cocoa fractions, from beans to chocolate;and second, to apply and demonstrate the use of the ComDim method for analyzing multi-block datasets generated by the same analytical technique. While principal component analysis was used to provide insights into individual datasets, ComDim revealed complementary information across all data tables, enhancing data interpretation. Cocoa pulp reduction and inclusion of malt residue and banana peel partially affected the volatile composition of cocoa beans, nibs, liquor, and chocolate. The results indicated that cocoa beans and nibs were more affected by fermentation treatments than liquor and chocolate. This study not only advances the understanding of cocoa volatile chemistry but also highlights the potential of circular economy practices by incorporating valuable co-products into cocoa fermentation, thereby enhancing sustainability and adding value throughout the cocoa supply chain. © 2024

Urban in Indonesia, is no longer limited as a center of community settlement. Now the city also functions as a center of government, a central hierarchy, and a center of economic growth. As a logical consequence of the role of cities as a center of growth and economy, urban contributions to national economic growth are increasing. To overcome this problem, a portable conveyor of solar-energized drying system was designed. With the portable conveyor of solar-energized drying system, the dryer will be easily moved and flexible to use. The advantage of portable conveyor of solar-energized drying system is the drying process could be done continuously with a little human power. Therefore, this portable conveyor of solar-energized drying system is designed to use renewable energy sources. To examine the portable conveyor of solar-energized drying system, the foodstuff was used for a testing of ingredients. The portable conveyor of solar-energized drying system testing show that the amount of water content in the foodstuff reduced, the drying rate accelerate. In addition, the amount of heat energy needed for the drying process also reduced. Hence process of drying foodstuff more efficienct. © 2020 Published under licence by IOP Publishing Ltd.

This study describes the bone development during the intrauterine phase of the black agouti ( Dasyprocta fuliginosa ), discussing its relationship with the species’ adaptive strategies and comparing it with other precocial and altricial species. We analyzed 33 conceptuses (four embryos and twenty-nine fetuses) obtained through collaboration with local hunters in the Amazon. Mineralization measurements of the axial and appendicular skeletons were performed by ultrasonography using a 10–18 MHz linear transducer. The chronological order of occurrence of mineralization in relation to the total dorsal length (TDL) and to the percentage of the total gestational period (GP) was: skull, ribs, vertebral bodies, clavicle, scapula, humerus, radius, ulna, ilium, ischium, femur, tibia, and fibula (TDL = 8.2 cm, 48 % GP); metacarpi, metatarsi and pubis (TDL = 9 cm, 51 % GP); thoracic and pelvic limb phalanges (TDL = 13.2 cm, 65 % GP); carpus (TDL = 15.10 cm, 72 % GP) and distal row of tarsus (TDL = 19.6 cm, 87 % GP). Mineralization of the patella was not observed in any advanced fetus (fetus with> 80 % GP). Regarding secondary ossification centers, the first signs of mineralization were observed in the distal epiphysis of the radius, distal epiphysis of the femur, and proximal and distal epiphysis of the tibia (TDL = 13.2 cm, 65 % GP). Fetuses at birth (TDL > 21.5 cm, 93.5 % GP) showed mineralization in all primary centers, and in most secondary ossification centers. Black agouti neonates have a high level of precociality with well-developed skeletal system at birth, which promotes independent postnatal locomotion and dexterity to manipulate and forage in search of food. Our results can contribute to the monitoring of bone development in other wild species, providing parameters for the identification of gestational age and serving as a model for comparisons between precocial and altricial mammals, ultimately helping understand life history strategies in different species.

Studies of the reproductive functional morphology of chelonians are important to understand the reproductive physiology, anatomy, and endocrinology of these species. However, data on the reproduction of this group have been difficult to obtain because of their cryptic habits and as a result the consequent inefficiency of conventional field methods in detecting individuals in the wild. In this study, we obtained reproductive organs from 347 adult female yellow-footed tortoises ( Chelonoidis denticulatus ), one of the most hunted and traded land vertebrates in South America, donated by local sellers in a wild meat market in the Peruvian Amazon. We described the species’ reproductive cycle and the influence of climatic factors on reproductive performance. Of the sampled females, 116 (33.4%) were gravid and 231 (66.6%) were non-gravid, including 215 vitellogenic (62.0%) and 16 non-vitellogenic (4.6%). The mean number of ovarian follicles per female declined from 28.5 (<10 mm diameter), to 7.1 follicles (20–40 mm) to 3.2 follicles> 40 mm. Gravid females had in average 3.7 shelled eggs in the oviduct, with a mean egg diameter of 53.7 mm. The estimated annual reproductive potential in gravid females was 5.1 eggs per clutch, ranging from one to 22 eggs. There was a strong positive relationship between the diameter of shelled eggs and the straight carapace length of gravid females. The final phase of the folicular growth, the most demanding energetic process in chelonian reproduction, correlated with annual rainfall peak, while oviposition was estimated to occur in the dry season. The yellow-footed tortoise should be considered an opportunistic seasonal breeder, though capable of reproducing throughout the year. Reproductive yields are linked to climatic events that influence food availability in the environment. To improve the sustainable use of this species, adult females should be harvested primarily during reproductive quiescence, from the end of the laying period in the

This work studies physical and mechanical properties of limestone cement pastes blended by TiO2 nanoparticles (i.e., particle size less than 100 nm). Three mixtures of 5,10 and 25 wt% of limestone partially replaced cement/clinker by TiO2 nanoparticles. Fillers are carefully selected which reinforcing cement workability or water retention they could be inert or have slightly hydraulic properties. Limestone is most common filler that fills the pores between cement particles due to the formation of monocarboaluminate, while nanoparticles increase the hydration C-S-H gel product and calcium titanium silicate which hardened the cement pastes. Nanoparticles show a great effect in reinforcing the mechanical strength of cement pastes due to the fact that TiO2-nanoparticles act as active nuclei site forming C-S-H gel observed as honeycomb-like plus improving cement to water demined (W/C) ratio. SEM analysis proves that the morphology of cement structure is well arranged and compacted leads to enhance the compressive strength by 20%. © 2018 Trans Tech Publications Ltd, Switzerland.

Railway transportation is critical to the flow of goods, primarily those with low added value and high cargo volume. In this paper, we report findings from a case study featuring interviews with five companies regarding the railway situation in the state of Piauí, Brazil. The results reveal that the railway system loads adopted in Piauí are restricted due to the low availability of routes and poor-quality infrastructure, which increase lead times. Moreover, we found that since the railways are not connected along main production routes, trains cannot be used to export goods. © 2017 Kedge Business School.

The purpose of this paper is to present a multicriteria methodology with spatial visualization, in order to identify most vulnerable areas regarding violence. We used Dominance-based Rough Set Approach to aggregate social, economic, and demographic characteristics, as well to include the preferences of a decision maker. Among the multicriteria methods, this one has the advantage of do not require the establishment of parameters, such as weights and thresholds. The decision maker only needs to choose a set of reference examples that represents his opinion toward the problem. This method applies decision rules to classify the set of alternatives. In this paper, this methodology was used aiming to classify the census tracts of a city in relation to the vulnerability to homicide. The result is a classification of all 1,854 census tracts of the city of Recife (Brazil) into five vulnerability levels. Based on this application, we can conclude, therefore, that this method may be useful to define where public policies should be allocated, when it is concerned with reduction of violence. © 2016 IEEE.

The COVID-19 pandemic triggered unparalleled political, economic, and social ramifications, exacerbating global food insecurity (FI). To understand the overall impact of the pandemic and how different socio-economic groups were affected, we assessed prevalence and severity of FI in a sample of 18,997 households across seven countries in South America. We employed the Food Insecurity Experience Scale developed by the FAO. Our results showed that pre-pandemic, 4.5% of the sampled population across the entire continent faced Moderate FI, while 0.6% experienced severe FI. During the pandemic, Moderate FI increased to 16.9% (+ 12.4%), and Severe FI to 2.7% (+ 2.1%). By country, pre-pandemic households in Venezuela had the highest prevalence of Moderate FI (9.7%), with Peru experiencing the highest Severe FI frequency (1.1%). Peru had the greatest rise in Moderate (+ 23.9%) and Severe FI (+ 4.6%) during the pandemic. Low-income households, defined as those earning < 2 minimum wages per month, were most susceptible to FI. Uruguayan low-income families exhibited the most significant rise (+ 40.4%) in Moderate FI, while those in Peru experienced an increase of + 9.1% in Severe FI. This study measures the profound and far-reaching impact of the COVID-19 pandemic on FI in South America. Our findings also emphasise the critical importance of implementing effective public policy interventions to improve resilience against future shocks. This would enable policymakers to develop targeted strategies that address the immediate challenges posed by pandemics as well as laying the groundwork for a more resilient and sustainable food security landscape in the region. © The Author(s) 2025.
