Optimization of cassava dried noodle using hydrocolloid and protein isolates: a tropical noodle
(2020-11-29)
Cassava flour has the potential to be used as a substituent of flour in making dry noodles. This study aims to obtain the optimum formulation of flour, hydrocolloid content and protein isolate content. Formula optimization of cassava noodle has been done by using two types of cassava flour: native and pre-gelatinization, adding additional food additives such as hydrocolloid (xanthan gum and konjac glucomannan) and pea protein isolate. The design of the formulation and optimization is done by D-optimal combined design ...

On the Trail of Creativity: Dimensionality of Divergent Thinking and its Relation with Cognitive Abilities, Personality, and Insight
(2020-12-02)
Divergent thinking (DT) is an important constituent of creativity that captures aspects of fluency and originality. The literature lacks multivariate studies that report relationships between DT and its aspects with relevant covariates, such as cognitive abilities, personality traits (e.g. openness), and insight. In two multivariate studies (N = 152 and N = 298), we evaluate competing measurement models for a variety of DT tests and examine the relationship between DT and established cognitive abilities, personality ...

Reaction to a low-carbon footprint food logo and other sustainable diet promotions in a UK University’s Student Union ‘Living Lab’
(2021-02-21)
Purpose: Public sector catering outlets have been proposed as ideal places to try new sustainable food choice interventions. We report on promotions conducted as part of a “Living Lab” at the University of Sheffield Students Union during 2019.Methodology: Activities include 1) a survey of dietary habits, attitudes and knowledge of staff and students (n=643). 2) A low environmental impact indicator logo was created and implemented in different ways across four food outlets in the Students Union (some outlets also ...

Awareness creation of smallholder farmers on and adoption of push-pull technology reduces fall armyworm (Spodoptera frugiperda) infestation on maize in Hawzien Woreda, Northern Ethiopia
(2020-11-28)
Recently, maize (Zea mays L.) production by smallholder farmers in Ethiopia has been threatened by an exotic pest called fall armyworm (FAW) (Spodoptera frugiperda J.E. Smith; Lepidoptera, Noctuidae). Devising or adopting sustainable, effective, affordable and smallholder farmers-friendly management strategies for the control of this pest are, therefore, vital. Push-Pull Technology (PPT) is considered one of the management methods for the control of FAW in East Africa. Therefore, the aim of this study is to determine ...

Diversification of maize-based intercropping systems in tropical rainforest agroecosystem of Nigeria: productivity, profitability and soil fertility
(2021-02-07)
Monocropping of maize is becoming unsustainable in the rainforest agroecosystem of Nigeria. This is due to the adverse impact of climate change such as increasing pests and disease infestations and erratic rainfall patterns coupled with underutilization of resources. Smallholder farmers in this tropical agroecosystems are in dire need of adaptive and resilient cropping systems to ensure food, nutrition, and livelihood security. Thus, this study aims to identify adaptive maize-based systems for the rainforest agroecology ...

Evaluation of antioxidant activity of the phenolic composition of Syrian Arbutus andrachne L.
(2020-10-18)
Arbutus andrachne L. (Grecian Strawberry tree) is widespread in the Mediterranean and the Black Sea Regions. This study aimed at determining total phenolic content and antioxidant activity of Arbutus andrachne parts (flowers, leaves, bark and fruit) collected from different parts of the Latakia Province (Syria). Our work is the first to conduct this experiment on the selected plants in Syria.
The fresh samples were extracted using ethanol 50% as an extraction solution, then the total contents of the phenolic compounds ...

Food traceability system awareness and agricultural operation: A Study of tea farms in Fujian, China
(2020-10-18)
China is establishing a Food Traceability System (FTS), but the policy implementation is behind most developed countries. The lack of FTS awareness may be a factor contributing to farming practices that are not consistent with FTS policies. Furthermore, the structure of an agri-food supply chain is a factor influencing farms’ compliance with FTS. The present study focuses on pesticide residue control and traceability issues in one of the largest tea production areas in China. It aims to examine the effect of FTS ...

Farmers’ Supply Response and Perception of Rice Procurement Program in Bangladesh
(2020-10-18)
Rice farmers in Bangladesh do not get proper returns due to lower market prices and many unexpected situations that may affect the supply of rice production. To protect the farmers, the government introduced the rice procurement program. This study tried to analyse the supply response to rice production and assess the farmers’ perception of government procurement program including their financial risk of rice production. Vector autoregressive (VAR) model was employed to analyse the supply response of rice using ...

Does backyard-keeping of native sows by smallholders in Quezon, Philippines, offer sustainability benefits compared to more intensive management of exotic sow breeds?
(2020-04-03)
The present study in Quezon, Philippines, assessed the sustainability of small-scale production systems, based either on native or on exotic sow breeds, using different survey tools in a socio-economic approach. In two research periods, data sets with 49 households and 68 households, respectively, all smallholder farmers keeping ≤5 sows, were compiled. In 2016, four municipalities were purposively selected, each representing one of Quezon’s four districts. In 2017, two municipalities, both with larger populations of ...

Parameter identification of crack-like notches in aluminum plates based on strain gauge data
(2020-12-31)
The identification of crack parameters and stress intensity factors in aluminum plates under tensile loading is in the focus of the presented research. In this regard, data of strain gauges, distributed along the edges of the samples, are interpreted. In the experiments, slit-shaped notches take the role of cracks located in the interior of the specimens. Their positions, inclinations and lengths as well as the magnitudes of external loadings are identified solving the inverse problems of cracked plates and associated ...
