In order to highlight the geology of the area studied, 14 samples were taken for studies using petrographic, geochemical and metallogenic methods. The study of macroscopic and microscopic petrography made it possible to highlight two major lithological units: 1) a volcano-plutonic unit, formed of gabbros, basalt, volcaniclastics and rhyodacite;2) a sedimentary unit (microconglomerate). From a geochemical point of view, the results obtained indicate that the plutonites are gabbro and gabbro diorite while the volcanics have compositions of basaltic andesites, rhyolite and dacites. The sediments have a litharenitic to sublitharenitic character. The metallogenic study made it possible to highlight hydrothermal alterations and metalliferous paragenesis on the formations studied. Hydrothermal alteration is characterized by the presence of carbonation, silicification, sericitization, sulfidation and to a lesser degree chloritization. Metalliferous paragenesis consists of pyrite, chalcopyrite, hematite and magnetite.展开更多

These countries, located in regions prone to unpredictable temperature and precipitation changes, are facing significant challenges, particularly in climate-sensitive sectors such as mining and agriculture. LDCs need more resilience to adverse climate shocks but have limited capacity for adaptation compared to other developed and developing nations. This paper examines Liberia’s susceptibility to climate change as a least developed country, focusing on its exposure, sensitivity, and adaptive capacity. It provides an overview of LDCs and outlines the global distribution of carbon dioxide emissions. The paper also evaluates specific challenges that amplify Liberia’s vulnerability and constrain sustainable adaptation, providing insight into climate change’s existing and potential effects. The paper emphasizes the urgency of addressing climate impacts on Liberia and calls for concerted local and international efforts for effective and sustainable mitigation efforts. It provides recommendations for policy decisions and calls for further research on climate change mitigation and adaptation.展开更多

This paper firstly analyzes the condition and situation of the small and medium-sized enterprises’ strategic alliance. Then it points out that the small and medium-sized enterprises should choose a suitable alliance organization, ally themselves with big enterprises, strive for the support of the government, and develop their technology through technology unions. Finally, it suggests that the government should create better innovation environment for R&D strategic alliance. A new way is also put forward for the application and foundation of the small and medium-sized enterprises’ R&D strategic alliance in China. It is also helpful for the sustainable development of small and medium-sized enterprises.展开更多

However, with the deepening of policy implementation, the main subjects, science and technology department, tax department, and technology company, are having some problems, which has a negative impact on the implementation of the deduction policy.This paper reorganizes the main policy of enterprises' R&D expenditure deduction and analyses the reality that "three party" are facing, then gives some advice to the regulation of R&D expenditure deduction policy.展开更多
