scholarly journals Evaluation of the Nutrient Composition of Fruits Selected From Different Markets in Lagos, Nigeria Together With Their Heavy Metals Contents

Introduction: Fruits are a form of staple food for humans obtained naturally. They contain various quantities of essential nutrients in the right proportion. Intake of fruits in the diet is usually a very heathy lifestyle as fruits prevents disease and keeps us healthy. Ingestion of trace amount of heavy metals through fruits leads to bioaccumulation producing serious health hazards. The aim of the study is to investigate the amount of heavy metals in fruits obtained from different markets in Lagos, Nigeria. Materials and methods: Five trace metals and five toxic metals were analyzed in different fruit samples obtained from Lagos, Nigeria using the atomic absorption Spectrophotometer. Proximate analysis was carried out to determine the nutrient composition of the fruits. Result: The result showed that 80% of the composition of fruits is made of moisture content. The carbohydrate content in fruits is about 10% while crude fibre makes up about 2%. From the analysis of trace metals carried out, paw paw (7.71 mg/kg) had the highest amount of zinc content followed by pineapple (6.60 mg/kg). Iron is high in pears (3.12 mg/kg) and Banana (2.26 mg/kg) while it is lowest in apple (0.59 mg/kg). Copper and Mn ranged from 0.40 t0 2.20 mg/kg. Analysis of the toxic heavy metals showed that lead ranged from 0.0 mg/kg to 0.12 mg/kg in carrot. This is high. Cd range from 0.0 in orange to 0.14mg/kg in apples. Cr ranged from 0.01mg/kg in healthyto 0.07mg/kg in orange. Nickel is highest in banana (9.21mg/kg) and lowest in water melon (0.37mk/kg). Conclusion: Bioaccumulation of these heavy metals over time can be hazardous to health. It is better for the government to check the sources of these heavy metals and remediate them so as to prevent the exposure of the populace to diseases.

The proximate analysis of the fruit sample that homogenously sampled from the wild was taken and quartered to get appreciable weight fit for analysis. Due to it perishable nature the quartered sample for each of the fruit was stored in an air tight container and kept in the refrigerator at a temperature of about 4°C. For the determination of the nutritional composition, parameters which include their proximate, minerals, and vitamin C were quantitatively determined while the anti-nutrient composition were qualitatively and quantitatively analyzed. Compared to ackee’s apple, monkey cola was found to consist of 64.41% moisture content, 1.69% ash, 10.21% crude fibre, 1.25% crude fat, 4.44% crude fibre, 18.06% carbohydrates while ackee’s apple consist of 73.21% moisture, 1.49% ash, 9.38 % crude protein, 13.98% crude fat, 2.08% crude fibre, 0.86% carbohydrates and 4.45% of vitamin C. The mineral analysis for both samples was quantitatively determined using Atomic Absorption spectrophotometer (AAS). The minerals determined for ackee’s apple and monkey cola were magnesium which was 1391.65 ppm, calcium 628.23 ppm, sodium 506.96 ppm, potassium 3976.14 ppm, iron 1.0 ppm, copper 5.00, zinc 4.00, cobalt 3.0 and phosphorus 2616.90 ppm the iron however, was not detected. Ackee’s apple on the other hand, consist of magnesium 498.01 ppm, calcium 478.56 ppm, sodium 398.80 ppm, potassium 4970.18 ppm, copper 2.00, zinc 5.00, cobalt 3.0 and phosphorus 373.84 ppm. The qualitative screening of the anti-nutrients revealed the absence of phenol from both fruit samples while tannins were present only in the monkey cola. The flavonoids, phytic acid and oxalate were quantitatively determined to be 1240 mg, 625 mg and 155 mg for Monkey kola and 640 mg, 340 mg and 65 mg for Ackee’s apple.

This study was undertaken to investigate the nutrient composition and sensory properties of wheat flour bread substituted with defatted and undefatted cashew kernel flours. Cashew kernel was processed into flour and thereafter divided into two portions. One portion was left undefatted while the other portion was defatted using a hydraulic press. Bread was prepared from the blends of wheat and defatted/undefatted cashew kernel flours using 90:10, 80:20, 70:30, of wheat flour to defatted cashew kernel flour (DCF) and wheat flour to undefatted cashew kernel flour (UCF), and 100% wheat flour as control. Bread samples were subjected to sensory evaluation within 30 minutes of production. Proximate analysis and amino acid profile of the bread samples were carried out using standard methods. Result of the proximate analysis of the bread samples revealed a significant (p<0.05) increase in ash (1.05-2.19%), protein (8.46-34.22%) and crude fibre (1.85-6.20%) with a corresponding decrease in moisture (11.05-21.28%) and carbohydrate contents (57.21-36.37%) as substitution of wheat flour with DCF and UCF increased. Amino acid analysis revealed that wheat/DCF composite breads were significantly (p<0.05) higher in lysine (7.00 g/100 g), phenyl alanine (3.99 g/100 g), tryptophan (0.89 g/100 g), valine (4.33 g/100 g) and methionine (1.47g/100 g) than the wheat/UCF composite bread. Similarly, wheat/DCF composite breads were significantly (p<0.05) higher in proline (3.45 g/100 g), arginine (5.68 g/100 g), tyrosine (3.78 g/100 g), alanine (4.25 g/100 g), glutamic acid (11.81 g/100 g), glycine (3.06 g/100 g), serine (4.00 g/100 g) and aspartic acid (7.32 g/100 g) indicating higher protein quality in the wheat/DCF composite breads than in wheat/UCF composite breads. Bread samples substituted with 10% UCF and 20% DCF compared favourably with the control wheat flour bread for taste, crust, colour and general acceptability. Therefore, it is recommended to use a level of substitution of 10% UCF and 20% DCF for the production of bread of adequate nutritional and sensorial qualities.

Saint Martin’s Island is a unique coral island in Bangladesh. Locally available fish species (both fresh and dry fish) were collected from the island to study moisture, ash, fat, protein content, fatty acid compositions and heavy metals. Fish oil was extracted from samples by solid phase dispersion method and fatty acid compositions were analyzed by GC-FID. Protein content in fresh fish samples was determined by the micro-Kjeldahl method.  Homogenized samples were digested, filtered and analyzed by AAS for determining toxic heavy metals in the fish samples. The fresh fishes appear to be a good source of dietary protein. Journal of Bangladesh Academy of Sciences, Vol. 44, No. 2, 191-195, 2020

Facing the decisive struggle between Nazism and Soviet communism for dominance in Europe, in 1942/43 Polish communists sojourning in the USSR espoused anti-German concepts of the political right. Their aim was an ethnic Polish ‘national communism’. Meanwhile, the Polish Workers’ Party in the occupied country advocated a maximum intensification of civilian resistance and partisan struggle. In this context, commentaries on the Nazi judeocide were an important element in their endeavors to influence the prevailing mood in the country: The underground communist press often pointed to the fate of the murdered Jews as a warning in order to make it clear to the Polish population where a deficient lack of resistance could lead. However, an agreed, unconditional Polish and Jewish armed resistance did not come about. At the same time, the communist press constantly expanded its demagogic confrontation with Polish “reactionaries” and accused them of shared responsibility for the Nazi murder of the Jews, while the Polish government (in London) was attacked for its failure. This antagonism was intensified in the fierce dispute between the Polish and Soviet governments after the rift which followed revelations about the Katyn massacre. Now the communist propaganda image of the enemy came to the fore in respect to the government and its representatives in occupied Poland. It viewed the government-in-exile as being allied with the “reactionaries,” indifferent to the murder of the Jews, and thus acting ultimately on behalf of Nazi German policy. The communists denounced the real and supposed antisemitism of their adversaries more and more bluntly. In view of their political isolation, they coupled them together, in an undifferentiated manner, extending from the right-wing radical ONR to the social democrats and the other parties represented in the underground parliament loyal to the London based Polish government. Thereby communist propaganda tried to discredit their opponents and to justify the need for a new start in a post-war Poland whose fate should be shaped by the revolutionary left. They were thus paving the way for the ultimate communist takeover

Purpose. The purpose of the article is to analyze and systematize the views of social and political thinkers of Galicia in the 19th - beginning of the 20th centuries. on the right and manner of organizing a nation-state as a cathedral. Method. The methodology includes a set of general scientific, special legal, special historical and philosophical methods of scientific knowledge, as well as the principles of objectivity, historicism, systematic and comprehensive. The problem-chronological approach made it possible to identify the main stages of the evolution of the content of the idea of catholicity in Galicia's legal thought of the 19th century. Results. It is established that the idea of catholicity, which was borrowed from church terminology, during the nineteenth century. acquired clear legal and philosophical features that turned it into an effective principle of achieving state unity and integrity. For the Ukrainian statesmen of the 19th century. the idea of catholicity became fundamental in view of the separation of Ukrainians between the Russian and Austro-Hungarian empires. The idea of unity of Ukrainians of Galicia and the Dnieper region, formulated for the first time by the members of the Russian Trinity, underwent a long evolution and received theoretical reflection in the work of Bachynsky's «Ukraine irredenta». It is established that catholicity should be understood as a legal principle, according to which decisions are made in dialogue, by consensus, and thus able to satisfy the absolute majority of citizens of the state. For Galician Ukrainians, the principle of unity in the nineteenth century. implemented through the prism of «state» and «international» approaches. Scientific novelty. The main stages of formation and development of the idea of catholicity in the views of social and political figures of Halychyna of the XIX – beginning of the XX centuries are highlighted in the work. and highlighting the distinctive features of «national statehood» that they promoted and understood as possible in the process of unification of Ukrainian lands into one state. Practical significance. The results of the study can be used in further historical and legal studies, preparation of special courses.

Abstract: Abdul Karim Soroush judges that religious rule is incorrect assessment of the application of Islamic jurisprudence. In a religious society, Islamic jurisprudence obtains the right to govern. It is, of course, necessary to establish a kind of Islamic jurisprudence-based religious rule. Soroush firmly rejects it because such interpretation is too narrow. As for democracy, Soroush argues that the system used is not necessarily equal to that of the Western. On the contrary, Ayatollah Khomeini’s thoughts on religious rule are reflected in the so called wilayat al-faqih. It is a religious scholar-based government. Democracy, according to him, is the values of Islam itself, which is able to represent the level of a system to bring to the country’s progress. Principally, there are some similarities between the ideas of Ayatollah Khomeini and those of Abdul Karim Soroush in term of religiosity. They assume that it is able to sustain the religious system of government. The difference between both lies on the application of religiosity itself. Ayatollah Khomeini applies the concept of a religious scholar-based government, while Abdul Karim Soroush rejects the institutionalization of religion in the government or state.Keywords: Governance, democracy, Abdul Karim Soroush, Ayatollah Khomeini

This article aims to find out the developmentidea or paradigm through village financial management based on Law Number 6 of 2014 concerning Villages. In this study, the researcher used a normative research methodby examining the village regulations in depth. Primary legal materials are authoritatuve legal materials in the form of laws and regulations. Village dependence is the most obvious violence against village income or financial sources. Various financial assistance from the government has made the village dependent on financial sources from the government. The use of regional development funds is intended to support activities in the management of Regional Development organizations. Therefore, development funds should be managed properly and smoothly, as well as can be used effectively to increase the people economy in the regions. This research shows that the law was made to regulate and support the development of local economic potential as well as the sustainable use of natural resources and the environment, and that the village community has the right to obtain information and monitor the planning and implementation of village development.
