Functional strawberry and red beetroot jelly candies rich in fibers and phenolic compounds

Jelly candies have a poor nutritional value due to their primary ingredients, which include gelling agents and sugar. In comparison to commercial jelly candy, the aim of this study is developing a natural and healthy jelly candy using fresh fruit comparing with commercials. Three types of jelly candies were prepared (T1: 75% strawberry + 25% beetroot; T2: 50% strawberry + 50% beetroot; T3: 25% strawberry + 75% beetroot). Physico-chemical, phytochemical, microbial, and sensorial profiles of jelly candy were evaluated. The results showed the superior recipe was T1, which recorded the highest values of bioactive compound content. Therefore, it also had the highest antioxidant activity 52.55%. Otherwise, T2 was considered the most favorable recipe for sensory evaluation, which recorded the highest value of overall acceptability and other sensory properties. Decreasing moisture content in all treatments compared with control had a great effect of preventing microbial growth in all samples except control. Therefore, this study creates a new healthier alternative product with the same sensory parameters of commercial jelly candy for all consumer types, especially children. ACKNOWLEDGMENT: All authors are thankful to the Food Science Department and Food Processing Technology Program at the Faculty of Agriculture, Cairo University, Egypt for helping them for conducting a few practical experiments in their laboratories.
Influence of Etching Mode and Composite Type on Bond Strength to Biodentine Using a “No-Wait” Universal Adhesive

The purpose of this study was to compare the shear bond strength (SBS) of four resin-based composite materials to a silicate-based cement using a “no-wait” universal bond with self-etch (SE) and etch-and-rinse (ER) modes. Acrylic blocks (n=80, 2mm depth, 5mm diameter central hole) were prepared. The holes were filled with BiodentineTM (BD) and divided into 4 main groups (n=20) according to the composite resin type used: Group FZ250: FiltekTM Z250 Universal Restorative (microhybrid), Group SDR: SDR Plus U Bulk Fill Flowable (low-viscosity bulk-fill), Group FBP: FiltekTM Bulk Fill Posterior (high-viscosity bulk-fill), Group EF: EsFlow™ Universal Flowable Composite (nanohybrid). A ‘no-wait’ universal bond (Clearfil Universal Bond Quick) was used for bonding application. Then each group was divided into 2 subgroups according to the etching mode applied (ER and SE). SBSs were measured and stereomicroscope was used to identify the failure modes. Selected samples of fracture surfaces were imaged by SEM. Tukey’s post-hoc and One-way ANOVA tests were used to analyze data. There were statistically significant differences among the composite groups (p<0.05). When SDR showed the highest bond strength values in SE (17.13 ± 2.98 MPa) mode, FBP showed the lowest bond strength values in ER (8.89 ± 2.46 MPa) mode. The mean SBS was not different between the SE and ER modes (p> 0.05). The SBS of BD to the resin composites depends on the composite type but application of the ‘no-wait’ universal bond in different etching modes is regardless of the SBS of BD to resin composites.
Life Cycle Assessment on Electric Moped Scooter Sharing

Due to their small size and low energy demand, light electric vehicles (LEVs), such as electric moped scooters, are considered as a space efficient and eco-friendly alternative for mobility in cities. However, the growth of electric moped scooter sharing services raises the question of how environmentally friendly this business model is, considering the entire lifecycle. Due to the dynamic market and insufficient availability of public data on the business processes of sharing services only a few studies on the impact of shared electric mopeds are available. Especially there is a lack of research on the impacts of key operational logistic parameters of the sharing system. This paper aims to fill this gap by conducting a life cycle assessment using the example of an electric moped scooter manufactured and used in sharing services in Germany, based on different operating scenarios. The results show that e-moped sharing has a similar environmental impact on global warming potential, in terms of passenger kilometers, as public transport, especially if long product lifetimes as well as efficient operation logistics are realized.
Nacre-like alumina composites reinforced by zirconia particles

Nacre-like alumina is a class of bio-inspired ceramic composite manufactured by field-assisted sintering of green bodies made primarily of alumina platelets with an anisotropic microstructure. Here we investigate the addition of zirconia particles to enhance the mechanical properties of the composite. The resulting structure is a nacre- like anisotropic structure which features deflection and reinforcement during crack propagation. Monoclinic zirconia has no impact on the mechanical properties of the composite while tetragonal zirconia improves its fracture resistance properties. Both types of zirconia seem to slow down grain growth during sintering. The addition of zirconia stabilised in the tetragonal phase is thus a good option to obtain a composite with a fine microstructure and higher mechanical properties than a standard nacre-like alumina, with a flexural strength of 626 ± 39 MPa and a crack initiation toughness of 6.1 ± 0.6 MPa.m0. 5.
Designing an Energy-Resilient Neighbourhood Using an Urban Building Energy Model

A climate resilient city, perforce, has an efficient and robust energy infrastructure that can harvest local energy resources and match energy sources and sinks that vary over space and time. This paper explores the use of an urban building energy model (UBEM) to examine the potential for creating a near-zero carbon neighbourhood in Dublin (Ireland) that is characterised by diverse land-uses and old and new building stock. UBEMs are a relatively new tool that allows the simulation of building energy demand across an urbanised landscape and can account for building layout, including the effects of overshadowing and the potential for facade retrofits and energy generation. In this research, a novel geographic database of buildings is created using archetypes, and the associated information on dimensions, fabric and energy systems is integrated into the Urban Modelling Interface (UMI). The model is used to simulate current and future energy demand based on climate change projections and to test scenarios that apply retrofits to the existing stock and that link proximate land-uses and land-covers. The latter allows a significant decoupling of the neighbourhood from an offsite electricity generation station with a high carbon output. The findings of this paper demonstrate that treating neighbourhoods as single energy entities rather than collections of individual sectors allows the development of bespoke carbon reducing scenarios that are geographically situated. The work shows the value of a neighbourhood-based approach to energy management using UBEMs.

Hidden Mott insulator in metallic 
PdCrO2

There has been a long-standing debate on the coexistence between itinerant electrons and localized spins in the PdCrO$_2$ delafossite. By means of the charge self-consistent combination of density functional theory and dynamical mean-field theory, it is corroborated that despite overall remarkable metallic response, the CrO$_2$ layers are indeed Mott insulating. The resulting $k$-resolved spectral function in the paramagnetic phase is in excellent agreement with available photoemission data. Subtle coupling between the itinerant and Mott-localized degrees of freedom is revealed. Different doping scenarios are simulated in order to manipulate the electronic states within the inert layers. In particular, oxygen vacancies prove effective in turning the hidden Mott insulator into a strongly correlated itinerant subsystem. The present results may open a new venue in research on quantum materials beyond canonical classification schemes.
Prevalence and risk factors of Ascaris lumbricoides infection in children of Manusak Village, Kupang District, East Nusa Tenggara Province, Indonesia

ABSTRACT Worm infection is one of the health problems in all tropical countries, including Indonesia. The most frequent helminthiasis is the infection caused by the Soil-Transmitted Helminth. Primary school-age children are an age group that is susceptible to helminthiasis. Worm infections can cause a serious impact if left untreated with no clean and healthy lifestyle. This study was conducted to determine the prevalence and risk factors of STH in children of Manusak Village, East Kupang Subdistrict, Kupang District, East Nusa Tenggara Province, followed by the characterization of subjects. The analytic observational design with the cross-sectional study was applied to this research. Research subjects were 130 children aged 6-12 years old. The infection was diagnosed microscopically by the Katokatz method. Ascaris lumbricoides were the only species found infecting a total of 50 children (38.4%.). The distribution of ascariasis was higher in girls (30 or 23.08%) than in boys (20 or 15.38%), in children whose parents have no formal education (41 or 31.54%), and who their professions are a farmer. Poor hygiene and sanitation such as no washing hands with soap (27 or 20.77%) as well as the habit of not wearing footwear (47 or 36.2%) and bowel habit on the open areas (35 or 26.92%) are the risks factors causing the high incidence of A. lumbricoides in the studied area. Enlightenment to the parents regarding good personal and environmental hygiene and sanitation along with chemotherapy from the government and related agencies is needed to achieve a durable reduction of the burden of ascariasis and other STH infection.

Logistic Regression With Tangent Space-Based Cross-Subject Learning for Enhancing Motor Imagery Classification

Brain-computer interface (BCI) performance is often impacted due to the inherent nonstationarity in the recorded EEG signals coupled with a high variability across subjects. This study proposes a novel method using logistic regression with tangent space-based transfer learning (LR-TSTL) for motor imagery (MI)-based BCI classification problems. The single-trial covariance matrix (CM) features computed from the EEG signals are transformed into a Riemannian geometry frame and tangent space features are computed by considering the lower triangular matrix. These are then further classified using the logistic regression model to improve classification accuracy. The performance of LR-TSTL is tested on healthy subjects’ data set as well as on stroke patients’ data set. As compared to existing within-subject learning approaches the proposed method gave an equivalent or better performance in terms of average classification accuracy (78.95 ± 11.68%), while applied as leave-one-out cross-subject learning for healthy subjects. Interestingly, for the patient data set LR-TSTL significantly ( $p< 0.05$ ) outperformed the current benchmark performance by achieving an average classification accuracy of 81.75 ± 6.88%. The results show that the proposed method for cross-subject learning has the potential to realize the next generation of calibration-free BCI technologies with enhanced practical usability especially in the case of neurorehabilitative BCI designs for stroke patients.
Distributional impact of monetary policy in the UK: from conventional to unconventional policy

ABSTRACT We evaluate the income distributional effect of monetary policy in the UK for the period 1993–2019 using a mixed frequency approach and a high-frequency identification. Our results indicate that expansionary monetary policy increased income inequality during the unconventional policy subperiod 2009–2019. Looking at the income brackets, we find that this increase in inequality is primarily due to the positive impact of expansionary policy on the upper share of income distribution. Our counterfactual analysis reveals that unconventional monetary policy contributed to the increase in inequality and that the response to COVID-19 is likely to do the same.
The Status of the Coral Reefs of the Jaffna Peninsula (Northern Sri Lanka), with 36 Coral Species New to Sri Lanka Confirmed by DNA Bar-Coding

Sri Lanka, an island nation located off the southeast coast of the Indian sub-continent, has an unappreciated diversity of corals and other reef organisms. In particular, knowledge of the status of coral reefs in its northern region has been limited due to 30 years of civil war. From March 2017 to August 2018, we carried out baseline surveys at selected sites on the northern coastline of the Jaffna Peninsula and around the four largest islands in Palk Bay. The mean percentage cover of live coral was 49 ± 7.25% along the northern coast and 27 ± 5.3% on the islands. Bleaching events and intense fishing activities have most likely resulted in the occurrence of dead corals at most sites (coral mortality index > 0.33). However, all sites were characterised by high values of diversity (H’ ≥ 2.3) and evenness (E ≥ 0.8). The diversity index increased significantly with increasing coral cover on the northern coast but showed the opposite trend on the island sites. One hundred and thirteen species of scleractinian corals, representing 16 families and 39 genera, were recorded, as well as seven soft coral genera. Thirty-six of the scleractinian coral species were identified for the first time on the island of Sri Lanka. DNA barcoding using the mitochondrial cytochrome oxidase subunit I gene (COI) was employed to secure genetic confirmation of a few difficult-to-distinguish new records: Acropora aspera, Acropora digitifera, Acropora gemmifera, Montipora flabellata, and Echinopora gemmacea.
Determinants of Behavioral Intentions to Use Sharia Financial Technology (Fintech)

The growth of sharia fintech is not proportional to the majority of the Muslim population. There are only a few studies that discuss the behavioral intentions of consumers who use sharia fintech. This study aims to identify the factors influencing Muslim's behavioral intentions in using sharia fintech. This study conducted 400 respondents in four types of sharia fintech (digital payment, lending, crowdfunding, and risk and management). This study uses a structural Equation Modeling - Partial Least Square (SEM-PLS) approach. Variable Planned behavior (PB), Acceptance Model (AM), Use of Technology (UT), Digital Literacy (DL), and Sharia Financial Literacy (SFL) have significant positive effects on Behavior Intention (BI). This study provides recommendations to improve the distribution of internet access infrastructure and the right curriculum in increasing digital literacy, Islamic finance literacy, and also more accessible fintech services.JEL Classification: D83, D91, G2, Z1How to Cite:Setiawan, D. , Darwanto. , & Gunanto, E.

Aims: knowledge of the patient’s profile, for the evaluation and suggested behaviors, promotes a favorable outcome. Thus, the objective of the study is to analyze the socioeconomic, clinical, and immunological characteristics of patients infected by the human immunodeficiency virus in the western region of the state of Pará. Methods: were analyzed 1966 medical records of patients whose first visit to a reference center, in the municipality of Santarém-PA, was between 1998 and 2018. Socioeconomic, clinical, and immunological information was collected from patient medical records. Data were analyzed using descriptive and inferential statistics, adopting p <0.05. Results: there was a predominance of males (62.5%), aged 20-39 years (69.1%), elementary school (58.6%), single (57.3%), and employed (66.4%). Immunosuppression was present in 22% of patients and a viral load was detectable in 66%. Tuberculosis (37%) and toxoplasmosis (23%) predominated as opportunistic infections, and syphilis (62.6%) and human papillomavirus (HPV; 14%) as other infections.Conclusions: it is concluded that both opportunistic infections and other infections were present in 25-22% of the patients and that the presence of opportunistic infections favors the installation of another infection, or vice versa. Toxoplasmosis, HPV, and syphilis are positively associated with men, and toxoplasmosis and tuberculosis with age >35 years. Immunosuppression was shown to be positively associated with men and age >35 years, as well as favoring the onset of tuberculosis, toxoplasmosis, and detectable viral load.
Structural basis for the regulation of insulin-like growth factors (IGFs) by IGF binding proteins (IGFBPs)

Insulin-like growth factor binding proteins (IGFBPs) control bioavailability, activity and distribution of IGF-I and –II in the serum. The study reported in this thesis employed techniques of nuclear magnetic resonance and X-ray crystallography to gain a more detailed understanding of the IGFBPs domain organization and structural requirements for binding to IGFs. This thesis presents structures of binary complexes between IGF-I and two amino-terminal domain constructs of IGFBP-4 and a model of the ternary complex of IGF-I, NBP-4 and the carboxyl-terminal domain.

1. First, it is not very clear to me what is the nature of the nonlinearities of the chemical module. Could you clarify that aspect (maybe when discussing Eq. 12)? If there are nonlinearities, what are their impact of the presence of these nonlinearities on the emergence of different solutions (for fixed parameters)? And would you please clarify (or comment) if this chemistry module could lead to complex dynamics (e.g. chaotic dynamics)?
Lower probability and shorter duration of infections after COVID-19 vaccine correlate with anti-SARS-CoV-2 circulating IgGs

The correlation between immune responses and protection from SARS-CoV-2 infections and its duration remains unclear. We performed a sanitary surveillance at the European Institute of Oncology (IEO) in Milan over a 27 months period. Pre-vaccination, in 1493 participants, we scored 266 infections (17.8%) and 8 possible reinfections (3%). Post-vaccination, we identified 30 infections in 2029 vaccinated individuals (1.5%). We report that the probability of infection post-vaccination is i) significantly lower compared to natural infection, ii) associated with a significantly shorter median duration of infection than that of first infection and reinfection, iii) anticorrelated with circulating antibody levels.
Geographic Partitioning of Dengue Virus Transmission Risk in Florida

Dengue viruses (DENVs) cause the greatest public health burden globally among the arthropod-borne viruses. DENV transmission risk has also expanded from tropical to subtropical regions due to the increasing range of its principal mosquito vector, Aedes aegypti. Focal outbreaks of dengue fever (dengue) in the state of Florida (FL) in the USA have increased since 2009. However, little is known about the competence of Ae. aegypti populations across different regions of FL to transmit DENVs. To understand the effects of DENV genotype and serotype variations on vector susceptibility and transmission potential in FL, we orally infected a colony of Ae. aegypti (Orlando/ORL) with laboratory and wild type DENV-1 through -4. Wild type DENVs were more infectious to and transmissible by ORL mosquitoes. We used these same DENVs to examine natural Ae. aegypti populations to determine whether spatial distributions correlated with differential vector competence. Vector competence across all DENV serotypes was greater for mosquitoes from areas with the highest dengue incidence in south FL compared to north FL. Vector competence for wild type DENVs was significantly higher, revealing that transmission risk is influenced by virus/vector combinations. These data support a targeted mosquito-plus-pathogen screening approach to more accurately estimate DENV transmission risk.
