Published: October 2019

The increasing global prevalence of dementia and the lack of disease-modifying treatments give rise to the need for early detection of dementia-causing diseases to enable the development and targeted administration of preventative interventions. However, current methods that have potential for the early detection of dementia-causing diseases, such as positron emission tomography or cerebrospinal fluid sampling, are invasive and costly, which constitutes a barrier to the large-scale assessment of dementia risk. The Early Detection of Neurodegenerative diseases (EDoN) initiative was established by Alzheimer’s Research UK to address this challenge. As part of EDoN, digital data and low-burden clinical measures, such as blood tests, will be collected in thousands of people to create machine learning models that can detect specific dementia-causing diseases decades before noticeable cognitive symptoms arise. This effort will be supported by the development of a data platform and a digital toolkit (likely consisting of wearables and smartphone applications) that will collect active and passive physiological and behavioural measures (e.g. cognition, mood, heart rate, gait, sleep, and navigation). After extensive testing, EDoN aims to introduce the digital toolkit into annual health checks, which will allow for the early detection of dementia-causing diseases in a cost-effective, low-burden manner on a population-wide scale. Moreover, the information derived from the digital data will be used to inform lifestyle changes and to triage and stratify individuals into clinical trials or further targeted medical testing. As such, the outputs of the EDoN initiative will benefit the public, patients, carers, and clinicians, as well as the broader healthcare system and the pharmaceutical industry.

Relevance Is Socially Rewarded, But Not at the Price of Accuracy
Authors: Altay Sacha , Mercier Hugo
Published: October 2019

Selecting good sources of information is a critical skill to navigate our highly social world. To evaluate the epistemic reputation of potential sources, the main criterion should be the relevance of the information they provide us. In two online experiments (N = 801) we found that receivers are more thankful toward, deem more competent, and are more likely to request information in the future from sources of more relevant messages—if they know the message to be accurate, or deem it plausible. To prevent sources from presenting information as more relevant than it is in order to improve their reputation, receivers lower the reputation of sources sending messages that are more relevant-if-true, if they know the message to be inaccurate. Our research sheds light on the reputational tradeoffs involved in choosing what information to communicate, and helps explain transmission patterns such as rumors diffusion.
Translation of findings from laboratory studies of food and alcohol intake into behavior change interventions: The experimental medicine approach
Authors: Field Matt , Christiansen Paul , Hardman Charlotte , Haynes Ashleigh , Jones Andrew , Robinson Eric , Reid Allecia
Published: October 2019

Objectives: Laboratory studies have contributed important information about the determinants of food and alcohol intake, and they have prompted the development of behavior change interventions that have been evaluated in randomized controlled trials conducted in the field. In this paper we apply a recent experimental medicine (EM) framework to this body of research. Methods: A conceptual review and focused discussion of the relevant literature is presented. Results: We illustrate how it is possible to translate findings from studies of food and alcohol intake in the laboratory into interventions that are effective for changing behavior in the real world. We go on to demonstrate how systematic failures can occur at different stages within the EM framework, and how these failures ultimately result in interventions that are ineffective for changing behavior. We also consider methodological issues that may constrain the external validity of findings from laboratory studies including demand effects, participant characteristics, and the timing and dose of behavioral interventions. Throughout, we make recommendations to improve the translation of findings from laboratory studies into behavior change interventions that are effective in the field. Conclusions: Consideration of the EM framework will help to ensure that promising candidate interventions for eating and drinking that are identified in laboratory studies can fulfill their translational promise.
Solitude as an Approach to Affective Self-Regulation
Authors: Nguyen Thuy-vy Thi , Ryan Richard , Deci Edward L.
Published: October 2019

In this research we showed that solitude generally has a deactivation effect on people’s affective experiences, decreasing both positive and negative high-arousal affects. In Study 1, we found that the deactivation effect occurred when people were alone, but not when they were with another person. Study 2 showed that this deactivation effect did not depend on whether or not the person was engaged in an activity such as a reading when alone. In Study 3, high-arousal positive affect did not drop in a solitude condition in which participants specifically engaged in positive thinking or when they actively chose what to think about. Finally, in Study 4, we found that solitude could lead to relaxation and reduced stress when individuals actively chose to be alone. This research thus shed light on solitude effects in the past literature, and on people’s experiences when alone and the different factors that moderate these effects.
Taking the pulse of social cognition: cardiac afferent activity and interoceptive accuracy modulate emotional egocentricity bias
Authors: Von Mohr Mariana , Finotti Gianluca , Villani Valerio , Tsakiris Manos
Published: October 2019

At the heart of social cognition is our ability to distinguish between self and other and correctly attribute mental and affective states to their origin. Emotional egocentricity bias (EEB) reflects the tendency to use one’s own emotional state when relating to others. Although interoception underpins our emotional experience, little is known about its role on how we affectively relate to others. Here, we assessed how cardiac interoceptive impact, manipulated by presenting affective stimuli across different phases of the cardiac cycle coupled with trait-like levels of interoceptive accuracy, modulate the EEB. Individuals with higher interoceptive accuracy displayed an increased EEB when the other’s emotional state was presented at the point of maximum interoceptive impact (i.e., at systole), whereas the reverse was observed for individuals with lower interoceptive accuracy. These findings show how interoceptive activity provides the physiological context within which we process other’s emotional states in parallel to ours.
Convertible Bond Valuation Model
Authors: Xiao Tim
Published: October 2019

This paper presents a new model for valuing hybrid defaultable financial instruments, such as, convertible bonds. In contrast to previous studies, the model relies on the probability distribution of a default jump rather than the default jump itself, as the default jump is usually inaccessible. As such, the model can back out the market prices of convertible bonds. A prevailing belief in the market is that convertible arbitrage is mainly due to convertible underpricing. Empirically, however, we do not find evidence supporting the underpricing hypothesis. Instead, we find that convertibles have relatively large positive gammas. As a typical convertible arbitrage strategy employs delta-neutral hedging, a large positive gamma can make the portfolio highly profitable, especially for a large movement in the underlying stock price.
Did Austerity Cause Brexit? Evidence from Aggregate Trends in Euroscepticism
Authors: Carl Noah
Published: October 2019

Fetzer (2018) presents evidence from analyses of panel data at the constituency and individual levels, which suggest that austerity measures implemented by the Conservative-led Coalition government may have caused an increase in the Leave vote share by up to 9.5 percentage points. If Fetzer’s hypothesis were correct, one would expect aggregate Euroscepticism to increase after 2010, during the period of austerity. However, analyses of three separate polling series suggest the opposite, namely that aggregate Euroscepticism declined between 2010 and 2015. A plausible interpretation of this finding is that Euroscepticism peaked around the time of the Eurozone debt crisis, and was not strongly affected by austerity.

This study aims to get an overview of the implementation of lectures in General Biology in the Chemistry Education FKIP Unsri. The sample of this study was Chemistry Education students in the 2018/2019 academic year (n = 43). The instruments used were documentation studies to find out the achievements of students in general Biology courses and survey questionnaires to find out the concepts that were considered the most difficult, the causes of difficulties understanding the concepts, and the interest of students in the quiz held before learning. The data shows that the achievement of student learning results shows 57.45% of students are still in the "C" and "D" assessment categories. Meanwhile, the concept of human physiology (41.86%) and cells (structure, metabolism, and reproduction) (39.53%) is the most difficult concept for students to understand. The difficulty of understanding this concept is due to the large number of uses of terminology (72.1%) and the weakness of students initial knowledge from previous levels of education (51.2%). These findings indicate the importance of diagnostic tests before the lecture is done so that the lecturer knows more about the weaknesses and strengths possessed by students so that the lectures that take place become more directed.

Published: October 2019

Background: Sarkar and Rashid (2016a) introduced a geometric way to visualize the mean based on either the empirical cumulative distribution function of raw data, or the cumulative histogram of tabular data.

Objective: Here, we extend the geometric method to visualize measures of spread such as the mean deviation, the root mean squared deviation and the standard deviation of similar data.

Materials and Methods: We utilized elementary high school geometric method and the graph of a quadratic transformation.

Results: We obtain concrete depictions of various measures of spread.

Conclusion: We anticipate such visualizations will help readers understand, distinguish and remember these concepts.
A Generalised Exponential-Lindley Mixture of Poisson Distribution
Authors: Sah Binod Kumar , Mishra A.
Published: October 2019

Background: The exponential and the Lindley (1958) distributions occupy central places among the class of continuous probability distributions and play important roles in statistical theory. A Generalised Exponential-Lindley Distribution (GELD) was given by Mishra and Sah (2015) of which, both the exponential and the Lindley distributions are the particular cases. Mixtures of distributions form an important class of distributions in the domain of probability distributions. A mixture distribution arises when some or all the parameters in a probability function vary according to certain probability law. In this paper, a Generalised Exponential- Lindley Mixture of Poisson Distribution (GELMPD) has been obtained by mixing Poisson distribution with the GELD.

Materials and Methods: It is based on the concept of the generalisations of some continuous mixtures of Poisson distribution.

Results: The Probability mass of function of generalized exponential-Lindley mixture of Poisson distribution has been obtained by mixing Poisson distribution with GELD. The first four moments about origin of this distribution have been obtained. The estimation of its parameters has been discussed using method of moments and also as maximum likelihood method. This distribution has been fitted to a number of discrete data-sets which are negative binomial in nature and it has been observed that the distribution gives a better fit than the Poisson–Lindley Distribution (PLD) of Sankaran (1970).

Conclusion: P-value of the GELMPD is found greater than that in case of PLD. Hence, it is expected to be a better alternative to the PLD of Sankaran for similar type of discrete data-set which is negative binomial in nature.

Authors: Maya Arni , Ginting Nurmaini , Tuah Sahlan
Published: October 2019

The problem faced is the lack of student interest; this is because biology subjects make students easily bored and assume biology is one of the difficult subjects. At the time of observation the teacher is more dominant in the learning process, so students' creativity is lacking. Learning models are needed that are appropriate learning models so as to be able to increase student creativity in sparking ideas, answers, solving problems or questions, skills in seeing problems from different points of view, the ability to give birth to new and unique expressions and able to improve students' abilities in terms of skills or develop students' ideas in the learning process. This type of research is classroom action research with a Number Head Together (NHT) type of cooperative learning model. The results of the first cycle students' creativity test results 78.94% while in the second cycle increased 5.27% with a percentage of 84.21%, the results of observations on students in the first cycle showed the results of 65.27% experienced an increase of 10.45% in the cycle II with the results of a percentage of 75.72% and the results of observations of the activities of teachers in the first cycle obtained 72% in the second cycle increased by 16% to 88%.

Remixing and Reimagining the Early Childhood School Experiences of Brilliant Black Boys
Authors: Wright Brian L. , Ford Donna Y.
Published: October 2019

As early as preschool, Black boys face low and negative expectations that contribute to excessive subjective-based discipline, over-referrals by teachers to special education, and under-referrals by teachers to gifted education. An increasing body of research demonstrates that the predominantly White female teaching force is complicit in allowing deficit thinking to compromise their views of Black boys’ languages, literacies, strengths, and cultural ways of being. We present an overview of these issues, with most attention devoted to gifted education, as it is a neglected topic when it comes to Black boys. We also share a formula for educators to adopt that sets minimum representation percentages in order to be equitable in gifted education for Black students in general and Black boys in particular.
Comparison of the effectiveness of isokinetic exercise vs isometric exercise performed at different angles in patients with knee osteoarthritis
Authors: Kilinc Serdar , Kabayel Derya D. , Ozdemir Ferda
Published: October 2019

BACKGROUND:

Strengthening exercises help improve physical function and muscle strength in knee osteoarthritis (OA). However, optimal exercise programmes for treating knee OA remain unclear.

OBJECTIVE

: To compare efficacy of isometric exercises performed at different angles and isokinetic exercises in patients with knee OA.

METHODS:

Patients were randomly divided into two groups. For four weeks, Group I ([Formula: see text] 15) and II ([Formula: see text] 17) patients with grade 2–4 performed isokinetic and isometric exercises at several different angles, respectively. Flexor and extensor knee muscle strengths were measured. Pain and physical function were assessed using VAS, WOMAC, the Lequesne Index and SF-36. All parameters were recorded at three time points: baseline (T0), after treatment (T1) and at 10-week follow-up (T2).

RESULTS:

VAS on movement, WOMAC, Leuqesne and SF-36 physical scores improved from T0 to T2 within each group, but Grade 3 and Grade 4 patients in the Group I showed better results compared with Group II at T2. Isokinetic exercise yielded higher extensor PM values than its isometric counterpart at T2 ([Formula: see text] 0.05) at 180[Formula: see text]/s for Grade 2 and Grade 3 patients.

CONCLUSIONS:

Both isokinetic and isometric exercises were effective in the treatment of knee OA of all grades in terms of pain reduction and functional improvements. However, isokinetic exercise produced longer lasting effects than isometric exercise.

Published: October 2019

BACKGROUND:

Four hemiplegia post-stroke patients with 10[Formula: see text]–30[Formula: see text] genu recurvatum recruited for three-dimensional gait analysis to investigate optimum inclination in a Rigid Tuned Ankle Foot Orthosis (RT-AFO).

OBJECTIVE:

1) To investigate the optimum inclination in a Rigid Tuned Ankle Foot Orthosis (RT-AFO) in order to stabilize stance knee kinematics in the sagittal plane for stroke patients with 10[Formula: see text]–30[Formula: see text] genu recurvatum, and 2) to compare the effects of RT-AFO with different inclinations on spatio-temporal parameters.

METHODS:

Three dimensional gait measurements were performed in five conditions for four participants: walk without AFO (T1), walk with RT-AFO in 0[Formula: see text] inclination (T2), walk with RT-AFO in 5[Formula: see text] inclination (T3), walk with RT-AFO in 10[Formula: see text] inclination (T4), and walk with RT-AFO in 15[Formula: see text] inclination (T5).

RESULT:

Application of tibial inclination in the AFO reduced the genu recurvatum in participants who experienced stroke. Genu recurvatum was significantly reduced in conditions T3, T4 ([Formula: see text] 0.001) and in T5 ([Formula: see text] 0.05). Optimum inclination was found at 15[Formula: see text] tibial inclination measured during mid-stance. This study reported a statistically significant improvement in cadence in condition T4 (RT-AFO 10[Formula: see text]) ([Formula: see text] 0.01). There were no significant results for improvement of walking speed and stride length.

CONCLUSION:

These results highlight the potential to optimize inclination of a Rigid Tuned Ankle Foot Orthosis for patients affected by stroke and also indicate the potential clinical applications of tuning the AFO in rehabilitation treatment of stroke patients.

Arthropods Associated with Corn Planted in the Marginal Uplands of Inopacan, Leyte
Authors: Ceniza Maria Juliet , Borines Rosalyn
Published: October 2019

A study was conducted to assess and identify the arthropods associated with corn planted in the marginal uplands of Inopacan, Leyte, using pan trap and sweep net methods, done biweekly during the two cropping periods. Two major groups of arthropods were recorded which included the Arachnids and the insect group, consisting of nine (11) orders of insects represented by 59 insects species and 20 spiders. These arthropods belonged to phytophagous groups (chewing and sucking arthropods); natural enemies (predators and parasitoids) and the innocuous groups or considered “others” (scavengers and saprophagous)
The most abundant insect pest species in corn were the Chrysomelidae and Scarabaeidae beetles, while leafhoppers (Homoptera) were moderately abundant in the crop. The predators were mostly ants (Hymenoptera), the spiders (Arachnids), and coccinellid beetles. The parasitoids included the braconid, ichneumonid, and chalcid wasps. The most abundant non-pest and innocuous species are the Dipterans which are potential hosts or prey of the biotic agents in the corn ecosystem.
The abundance of pest species in corn is not yet alarming, which indicates that the pests are not attracted to the crops which were marginal in growth. The natural enemies were also occurring in moderate numbers adequate to suppress abundance of pest species. However, from the results, the corn planted in the marginal upland with chicken dung was observed to have the higher number of insect associations than the other treatments.
Chemical Composition and In Situ Digestibility of Common Feed Resources for Ruminants in Marginal Uplands
Authors: Bestil Lolito , Atole Angelo Francis , Rama Jandells
Published: October 2019

This study assessed the chemical composition and degradation of in situ predominant feed resources for ruminants in the marginal uplands of Inopacan,Leyte, Philippines. These feed resources included basal grasses such as guinea (Panicum maximum), humidicola (Brachiaria humidicola), and carabao grass (Axonopus compressus); supplemental legumes such as calopo (Calopogonium muconoides), madre de cacao (Gliricidia sepium) and centro (Centrocema pubescens); foliages of trees/shrubs such as jackfruit (Artocarpus heterophylum Lamk) and abgaw (Premna odorata); and concentrates such as rice bran (D2) and squeezed grated coconut. Chemical analyses followed standard procedures, while trial was done by in situ incubating the feed samples in rumen-cannulated steer fed 70% basal/grass and 30% of the supplements.
Crude protein (CP) contents were 15.83 to 18.23% in legumes,10.17 to 11.91% in tree foliages, 5.16 to 8.51% in grasses, and 4.84 to 6.08% in concentrates on as-fed basis. Gross energy (GE) contents were high–5097kcal/kg in grated coconut (highest) and 2931 kcal/kg in humidicola grass (lowest). Calcium (Ca) and phosphorus (P) contents were low, ranging from 0.004 to 0.189% Ca and 0.026 to 0.037% P. Considering animal requirements, these indicated a potential adequacy in GE supply but a limitation in protein and Ca and P in marginal uplands. Dry matter degradation (DMD) was high in grated coconut, abgaw, calopo and madre de cacao (77.86 to 86.51%) among the supplements and in carabao grass (71.11%) of the basal, and low in humidicola and rice bran D2 (46.52 to 47.51%). Crude protein degradation (CPD) was highest in abgaw, calopo, madre de cacao, jackfruit and grated coconut (86.87 to 90.97%), moderate in guinea and carabao grasses and rice bran D2 (61.28 to 64.01%), and low in centro and humidicola (57.46 to 59.63%). Quantitatively, and across chemical composition and in situ degradation, the feeding of humidicola grass, centro legume, and rice bran D2 is least recommended.

The sows performance on the average litter size born/Average littersize at weaning for T0 (commercial feeds) was 9.33/6.33 hds., while T1 (commercial feeds + 20 ml HMP) was 11.0/10.33 hds, and T2 (commercial feeds + 20 ml HMP + crop-silage by-products @ 0.10% BW on DM basis) 9.67/8.67 hds, and the average weaning weight for T0 = 8.61kg, T1 = 01 9.23 kgs, and T2 = 8.35kgs, respectively. However,the total number of weaned piglets for each treatment resulted to a significant profitability (given the price per weanling equivalent to Php 2,000 per head) of the treatment assigned to sows productivity performance based on these results T0 = 19 hds (Php 38,000.00), T1 = 31 hds (Php 62,000.00), and T2 = 26 hds (Php 12 48,000.00). The introduction of crop-silage plus HMP technology increases the productivity of the sows and likewise, increases the profitability in terms of peso income after weaning the piglets of marginal upland area pig raisers.

Sweetpotato is one of the predominant crops grown by local farmers in the marginal uplands of Brgy. Linao, Sitio Batuan, Inopacan, Leyte. The need to produce quality food products from sweetpotato is a continuing challenge to open new opportunities for farmers and entrepreneurs alike. This study aimed to determine the potential of sweetpotato var.SP30 for flake production and conduct moisture adsorption isotherm studies. Two screening processes were made using the 7-variable 8-run Plackett-Burman design while a face centered Central Composite Design (CCD) was employed during optimization. Sensory evaluation results were subjected to response surface regression (RSREG) analyses to generate optimum processing condition(s). Moisture adsorption studies were carried out to determine the nature of the product isotherm based on Brunauer-Deming-Deming-Teller (BDDT) classifications. Fitting of data was done using the Bruanauer-Emmettand Teller(BET) and Guggenheim-Anderson de Boer (GAB) models to determine the amount of adsorbed moisture in the product during storage at different temperature levels.
Screening results identified Drying time (Dt), Drying Temperature (DT) and Oven Toasting time (OTt) as the critical processing variables. A set of combinations of Dt (min.), DT (°C), and OTt (min.) were generated as a result of the optimization. These combinations were 75-50-20, 80-50-20, 80-50-18, 85-50-20 and 90-50-20. Calculated values for the mass fraction of adsorbed water in the monolayer (WmB and WmG) at 30°C, 40°C and 50°C are 0.0971, 0.1311, 0.0591 and 0.1046, 0.2447 and 0.2224 respectively (expresseding/100gH2O)
Sweetpotato (var. SP30) was found suitable for flake production. Moisture adsorption isotherm of sweetpotato flakes was sigmoid in shape and classified as type II in the BDDT classification. Wm values for both BET and GAB were found to follow the relationship WmB < WmG (Timmerman,2003).
From Insecurity to Secondary Migration: “Bounded Mobilities” of Syrian and Eritrean Refugees in Europe
Authors: Tuzi Irene
Published: October 2019

This paper seeks to analyse Syrian and Eritrean refugees' mobility experience across European borders, in a framework of mobility and insecurity. Drawing on the conflict model of migration, the paper focuses on the effects of migration and asylum policies when these are not in line with refugees’ needs and aspirations. We argue that when the asylum system does not meet with those expectations, insecurity brings into play secondary movements, which occur in a framework of irregularity. The considerations behind this article are motivated by the empirical evidence that both Syrian and Eritrean refugees undertake irregular secondary migration, whilst being within a protection system that most of the times satisfies their asylum claims. This paper is the result of a qualitative research conducted in 2017 through observation, in-depth interviews with Syrian and Eritrean refugees, and consultations with experts and practitioners in Italy, Greece, Germany and Lebanon.
The identity and probable origin of the Hemidactylus geckos of the Maldives
Authors: Agarwal Ishan
Published: October 2019

The Maldives are coral reef islands of Holocene origin with no endemic terrestrial herpetofauna. The few species that have been reported from the region have affinities with Sri Lanka, south and south-east Asia, and are considered relatively recent introductions by humans. Recent collections of Hemidactylus geckos from the Maldives allowed us to identify and reconstruct the probable origin of this genus on the islands. We combine mitochondrial DNA (ND2) sequence data for the new collections with published sequences to reconstruct evolutionary relationships. The two species of Hemidactylus in the Maldives are H. frenatus and H. parvimaculatus, with affinities to south-east Asia and Sri Lanka, respectively. Suggestive of multiple introductions, each species included multiple haplotypes, only one of which was previously recorded (in Sri Lanka); other haplotypes showed similarities to records from south-east Asia. Unravelling the colonisation patterns of house geckos in the Maldives requires a more complete knowledge of the natural variation across the range of the widely distributed source species.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from December 2016 to May 2017 to investigate the effect of weeding regime on the performance of boro rice cultivars. The experiment comprised of two factors, Factor A-  Rice cultivars: BRRI dhan28, BRRI dhan29, and BRRI dhan74, Factor B: Methods of weeding- no weeding, two hand weedings at 15 and 35 DATs, application of pre-emergence herbicide Commit, application of early post-emergence herbicide Pediplus, application of pre-emergence herbicide Commit followed by application of early post-emergence herbicide Pediplus, application of pre-emergence herbicide Commit followed by one hand weeding at 35 DAT, and application of early post-emergence herbicide Pediplus followed by one hand weeding at 35 DAT. The experiment was laid out in a split plot design assigning rice cultivars in the main plots and weed management practices in the sub-plots with three replications. Fourteen weed species infested the experimental field belonging to six families. Among the weed species, four were grasses, four were broad leaves and six were sedges. Cultivar exerted significant effect on weed density and dry weight. Both the highest weed density and dry weight were found in BRRI dhan28 and the lowest ones were observed in BRRI dhan29 rice cultivar. Weed density and weed dry weight were significantly influenced by weeding regime. The highest weed density and dry weight were observed in no weeding condition and application of pre-emergence herbicide Commit followed by one hand weeding at 35 DAT showed the best performance. BRRI dhan29 produced the highest grain and straw yields among the cultivars. Weed control had pronounced influence on yield of rice. The highest grain yield was obtained in application of pre-emergence herbicide Pretilachlor (Commit)followed by one hand weeding at 35 DAT and the lowest one was obtained in control (no weeding) treatment. From the results of the study it may be concluded that rice cultivar BRRI dhan29 with application of pre-emergence herbicide Commit followed by one hand weeding at 35 DAT might be the best treatment for controlling weed effectively as well as obtaining highest yield and highest economic return.

Published: October 2019

Heavy metal accumulation in environmental compartments is a potential risk to the living system because of their uptake by plants and subsequent introduction into the food chain. A study was carried out to investigate the heavy metal contents in industrially contaminated soils collected from six different locations of Dhaka and Mymensingh districts and their effects on two important vegetables namely tomato and cabbage. Pot experiment was conducted using contaminated soils at the net house of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh following completely randomized design (CRD) with three replicates. The higher level of heavy metal contents was found in the soil samples of Hajaribag and Dhaka Export Processing Zone (DEPZ). The highest Ni, Cd, Cr, Cu and Fe contents were 59.45, 18.79, 67.57, 40.81 and 1619.61 µg g−1 which were much above the recommended level except Cu contents. The highest yield of vegetables was obtained grown in Maskanda soil of Mymensingh district and the lowest from DEPZ soil of Dhaka. The highest Ni, Cr and Fe contents were 8.91, 7.22, 419.65 µg g−1, respectively in tomato fruits grown in the soil of Hajaribag whereas the highest Cu content (3.38 µg g−1) was obtained from Seedstore soil, Mymensingh and highest Cd content (2.88 µg g−1) was from Mitford ghat soil, Dhaka. In cabbage, the highest Ni (17.52 µg g−1) and Fe (411.25 µg g−1) contents were found in the soils of DEPZ whereas the highest Cr (9.17 µg g−1), Cd (3.52 µg g−1) and Cu (8.51 µg g−1) were obtained in the plants grown in the soils of Hajaribag, Mitford ghat and Maskanda, respectively. Concentrations of all the tested heavy metals except Cu in both vegetables were above the maximum allowable limit prescribed by the World Health Organization. Among the metals, the accumulation of Ni was found as higher amount (0.39 and 0.71 for tomato and cabbage, respectively) based on plant concentration factor or transfer factor. The results showed a positive correlation between concentration of the metals present in soils and in vegetables and the highest correlation was found with Cr in tomato and Fe in cabbage. However, both the soils and grown vegetables were consistently observed to pose a risk to human health. So, it can be recommended that government should take necessary action so that heavy metals used in the industries cannot come into the nearby agricultural field to ensure food safety as well as food security.
