The creation of the Zone of Peace and Cooperation of the South Atlantic (ZPCSA) in 1986 and the Gulf of Guinea Commission (GGC) in 2001 was about changes in the distribution of world power. This article argues that though they emerged at different times, their strategic orientation converges in a number of areas related to the significant interests in the South Atlantic as an area of stability in the region to be marked by strong political, economic and military ties. They also converge on the ideal for development, security and greater projection of power and influence in international affairs. The South Atlantic being a route of passage and trade, as a means of access and flow of energy products, the region became a site for new calculations of regional strategic powers about world affairs. The article also argues that ZPCSA and GGC are therefore crucial for the regional order and the development of higher capacities for cooperation on strategic issues. The actual point of convergence extends to ensuring the sovereignty through dialogue between the states in the region that are involved.

According to judgemental forecasts, in the next few years the revolutionary changes in the energy complex both in the USA and in the world in general are hardly possible, considering the enormous inertia of the energetic system and high expenses coming from the infrastructure supersession, even in case of cost-effective alternatives to the existing energy commodities. At the same time, the sharpening of energy security problems resulting from the growth of a global demand on energy products leads to perceprion of necessity for a new approach to forming the global energy market, and to development of new stability and reliability strategies maintenance for assured supplies of energy products. In recent years, the USA as the biggest consumer of energy resources in the world worked out a new national strategy of energy security provision. Its main targets are: meeting the requirements of the American economy of its own resources, lowering the import-dependence level, high use of innovation technologies, significant increase of investments in alternative energy sources, as well as of resource-and energy-saving.

The article presents estimates of social minimum baskets for the second and third quarter of 2020, i.e. when the sanitary restrictions resulting from the COVID-19 pandemic took place. They obviously affected the functioning of households in various aspects. The presented estimates take into account the needs as foreseen in the model under normal conditions; the new circumstances of Covid-19 were not taken into account. There is lack of research data on changes in household consumption in 2020. If there will be a need to change assumptions in the model, the values of social minimum can be recalculated in the future. The value of the social minimum in the 2nd quarter increased by 2.1% in a one-person household and by 1.8% in a four -person household, with inflation by 0.3%.The increase in the subsistence minimum was mainly due to a further increase in food prices (from 4.3 to 4.5%), with the costs of housing and energy carriers rising from 1.7 to 2.0%. The very same factor contributed to a decline in the value of the minimum in the third quarter. In this period, the social minimum estimates decreased by -1% in a one-person household and by -1.1% in a four-person household, with a trace increase in CPI index (+0.1%). Seasonal decreases in food prices caused the value of food in the basket to decrease from -6.1 to -6.4%, with a CPI of -2.3% in this expenditure group. This time, expenditure on housing and energy products did not exceed 0.5%

Bulk isotropic and anisotropic Nd13.5Fe80.4Ga0.5B5.6 and Nd13.5Fe80.4Ga0.5B5.6/Fe magnets were synthesized by applying spark plasma sintering (SPS) technique. The effect of hot-pressing temperature on the magnetic properties of hot-pressed (HP) and hot-deformed (HD) magnets without additive and with 5% Fe addition was investigated. With increasing sintering temperature for HP magnets, the grain grew gradually. For HD magnets, the optimal magnetic properties could be obtained at hot-pressing temperature 680°C due to the development of desired c-axis texture and uniform microstructure, which resulted from the appropriate and uniform grain size in HP magnets. Fe addition could enhance remanence (Br) and magnetic energy products ((BH)m) of HP and HD magnets. However, the maximum magnetic energy product of HD magnets decreased when hot-pressing temperature was higher than 650°C.

Subsidizing electricity and non-electrical energy products has affected manufacturing output in Egypt, especially given the structure of Egypt’s manufacturing sector which leaning heavily towards capital- and energy-intensive products. This effect is captured in a production function estimated for the twenty industries making up Egypt’s manufacturing sector over the period 2002-2016. With homogeneous parameters, the estimated output elasticity of energy is 0.28. With panel member parameter heterogeneity, the output elasticity of energy is positive and statistically significant in ten manufacturing industries. Negative and statistically significant elasticity is however found in refined petroleum products, fabricated metal products, and electrical machinery and equipment. This indicates suboptimal energy use. Elasticity is also negative, though statistically insignificant, in: textiles, basic metals, and “other manufacturing”. Except for “other manufacturing”, industries of negative elasticity are all energy-intensive.  Moreover, refined petroleum, fabricated metals and basic metals are pollution-intensive. A priority policy measure is to remove subsidies from energy inefficient and polluting industries as opposed to mere ‘across-the-board’ removal. Keywords: energy consumption; manufacturing industries; energy- and pollution intensive; Egypt
