The present paper attempts to know if the confinement in Tunisia has an impact on the consumption of subsidized products and in turn on food security and on the trade balance or not. Firstly, by analyzing the place of subsidized products in Tunisian economy. Then via the determination of limits of confinement in Tunisia specially trade deficit. Finally through the analysis of different problems given by confinement on food security and increased of percentage of cancer. According to our analysis, confinement of COVID-19 pandemic has caused an unprecedented economic, food security and financial crisis in Tunisia especially on the trade deficit witch is suffer before of various difficulty. The confinement can be considred a good solution for COVID but it have many limits on food security for Tunisian and on incresed of consumption of subsidized products in Tunisia.

The fluorescence sensing properties of a naphthalene-based acetohydrazide (3) were investigated. A highly selective “turn-on” response was obtained towards Al3+ ions, and this was used for real sample analysis and development of paper test strips.

Trade balance per capita is one of the international trade indicators that experts frequently use to evaluate a country’s performance in trade and evaluate its commercial policies. Exports, imports and the trade balance per capita of the 21 APEC countries were calculated for the 2001-2014 period in order to observe and evaluate its recent evolution, especially for the Mexican case. The data used only covered merchandises according to their value in US dollars at constant prices of 2014. Results suggest the existence of trade surpluses in extractive economies such as Brunei, Papua New Guinea and Russia. The exponential growth of exports from Vietnam and China is also demonstrated as well as the outstanding international business activity in Singapore and Hong Kong (which in per capita indicators outweighed all of the other members of APEC). Conditions of trade deficit are detected for powerful economies such as United States and Japan. On the other hand, Mexico shows a balanced condition in this indicator, an important and growing automotive industry and a noteworthy dependence on the US economy.

Effective Exchange Rate

The current study empirically examines the three major approaches to trade balance for Pakistan by utilizing the yearly data from 1972 to 2016. Monetary, elasticity, and absorption approaches were tested by developing a model that incorporates all three approaches. The significant contribution of the study is that it uses only the merchandise trade deficit account, which includes trade of only physical goods. The study used time-series data; therefore, variables have been tested for the stationarity, and it is found that there is a combination of I (0) and I (1) variables, so ARDL bounds testing approach to co-integration has been employed to find the short run and long run associations among the variables. The bound test results discovered that there is a presence of stable long-term association among the merchandise trade deficit account, real broad money supply, real effective exchange rate, and real domestic absorption. The results further revealed that merchandise trade discrepancy is determined purely by the real effective exchange rate, which specifies that the exchange rate's devaluation increases the deficit in the long run whereas in the short-run increase in domestic absorption decreases the merchandise trade deficit.

Rapid Reaction

An efficient, sensitive, and low-cost method has been developed for turn-on fluorescence sensing of dopamine (DA). The method relies on the rapid reaction of DA and 3-Hydroxyphenylboronic acid (3-HPBA) via specific recognition between boronic acids and cis-diol of DA in alkaline solution. The reaction product shows an excitation wavelength of 417 nm and the maximum emission peak at 470 nm. The proposed method allows the determination of DA in the range of 50 nM–25 μM, and the whole detection can be completed within 5 minutes. Furthermore, the presented approach has good selectivity and has been successfully applied to DA sensing in human serum samples, showing great potential in clinical diagnosis.
