After the presentation of “The One Belt One Road”(OBOR) initiative, China has invested more than USD 14 billion to Djibouti. However, the Sino-Djibouti cooperation is still subject to many challenges.To gain a deeper understanding of the actual situation of Chinese enterprises’ investments in Djibouti under the “OBOR” initiative, this paper intends to conduct a survey among some of Chinese enterprises involved in the “OBOR” initiative as to the overall willingness, policy support, actual condition, and investment construction of Chinese enterprises’ investment projects in Djibouti, in order to gain a further insight into the investment development of Chinese enterprises in Djibouti in the next stage:Based on the analysis, although Chinese companies have very broad development prospects in Djibouti under  the “One Belt, One Road” initiative, they still need to adopt more scientific and reasonable development proposals in order to maximize the benefits from investments in Djibouti.

In today’s world, the field programmable gate array (FPGA) technology has advanced enough to model complex chips replacing custom application-specific integrated circuits (ASICs) and processors for signal processing and control applications. This project proposes a hardware/software co-simulation methodology using hardware description language (HDL) simulations on FPGA as an effort to accelerate the simulation time and performance [1, 2]. To accelerate the computation of the gesture recognition technique, an HW/SW implementation using field programmable gate array (FPGA) technology is presented in this project. The testing part of the neural network algorithm is being hardwired to improve the speed and performance. The American Sign Language gesture recognition is chosen to verify the performance of the approach. The major benefit of this design is that it takes only few milliseconds to recognize the hand gesture which makes it computationally more efficient.

With the rapid development of science and technology, the mobile devices which we use in daily lives have integrated more and more sensors and been able to replace some of the traditional sensors to collect data, which makes the mobile crowd-sensing network to become an academic research hot spot. The users selected by the sensing tasks of the mobile crowd-sensing network are mostly distributed densely and encountered frequently, and the performance efficiency of the sensing tasks is improved by utilizing the short range wireless communication (such as Bluetooth and Wi-Fi) with opportunistic transmission. Through the research and analysis of the data collection mechanism in the mobile crowd-sensing network and aimed at the deficiencies of the ecoSense mechanism on budget control and user incentive, we proposed a CoES mechanism. In this paper, we design compensation schemes for domestic users and control the budget through compensation ratio. In the aspect of user motivation, we design IOR user incentive mechanism. According to the amount of data uploaded by the user who act as a chance really and the information of device’s power, we analyze the cooperation workload and reward. Finally, we use SWIM data set for simulation experiments, the results show that our scheme compared with the direct-assignment scheme can effectively reduce the costs to 53%, compared with the ecoSense scheme can reduce 5% of the cost, and the efficiency increased with the increment of the amount of data.

An attempt to review the milestones of Cape Verdes hospitality industry, revealed how it has been growing as well as the issues it faces the development of modern tourism in Cape Verde has been accompanied by the growth of the tourism hospitality industry in Cape Verde over the decade. However, there has been little academic research work done on Cape Verde’s hospitality industry. Cape Verde is a typical example of a quality tourist destination on the in African continent and region, and has been leading the tourism development in Africa. An attempt to review the milestones of Cape Verde’s hospitality industry, revealed how it has been growing as well as the issues it faces. Objectively, discussing the opportunities and countermeasures for its development will be crucial to the sustainable development of Cape Verde’s hospitality industry, as well as the tourism development in Africa.

EDXRF analysis on akanwu, unpurified and purified palm bunch ash (Elaeis guineensis), saw dust ash (Khaya ivorensis), plantain peel ash (Musa sapientum), pawpaw leaves (Carica papaya), bitter leaf (Vernonia amygdalina), two species ogbonno (Irvingia gabonensis), achi (Brachystegia eurycoma), ofor (Detarium microcarpum), ukpo (Mucuna flagellipes) and okro (Abelmoschus esculentus) used as local agents for Enhanced Oil Recovery beyond conventional waterflooding showed the presence of major, minor and trace elements with its oxide in varying proportions. Unpurified palm bunch ash, purified palm bunch ash, saw dust ash, plantain peel ash and akanwu contain 56.03%, 56.996%, 22.41%, 54.15%, 12.65% and 3.55%, 4.91%, 0.512%, 2.64%, 5.877% of potassium oxide and sodium oxide respectively. The Loss On Ignition (LOI) test showed the presence of carbonate ions as 42.65%, 47.44%, 37.54%, 40.33% and 30.54% in unpurified palm bunch ash, purified palm bunch ash, saw dust ash, plantain peel ash and akanwu respectively.  This analysis confirmed that the local akanwu in Nigeria is Potash and not Trona as commonly mistaken. pH is a major criteria for a successful alkaline flooding. Pawpaw leaves and bitter leaf contains 56.41%, 22.66%, 1.66%, 1.37% and 53.14%, 27.28%, 0.66%, 5.68% of potassium oxide, calcium oxide, iron III oxide and sodium oxide respectively. Aluminium and lead were absent in both unpurified and purified palm bunch ash but lead was present in plantain peel ash and akanwu sediment, though absent in extract from akanwu but silicon oxide, aluminium oxide and titanium oxide were present in akanwu. Analysis on the local polymers used as food thickeners also showed that they contain major elements like potassium, calcium, sulphur, phosphorus and sodium but the absence of magnesium except for one of the species of ogbonno. Pawpaw leaves contain vital elements and oxide that makes it nutritional rich for human consumption like other vegetables. These local materials if modified and refined can substitute synthetic chemicals used for Enhanced Oil Recovery.

Emotional intelligence is fundamental to nursing practice and it influences professional relationships, impact patient care decisions and affect healthcare workers at an intrapersonal level. Across academic disciplines, there is strong acknowledgement that understanding the effect of emotional intelligence is essential. Hence, this study intends to quantitatively investigate the effect of emotional intelligence on the job performance of nurses in Jordanian nursing hospitals. Pertaining to this, a self-administered questionnaire was used and a total of 384 nurses in Jordanian hospital were randomly selected as respondents, in which their perceptions were gathered. The hypothesis was tested by using SEM-AMOS package 22.0 and the findings have shown a direct effect of emotional intelligence on Job Performance of Nurses in Jordanian Hospitals, which is positive and significant (β=0.222, P=.001). The novelty of the research goes back to studying the concept in a developing country, i.e. Jordan. The implications of the above findings are then discussed.

The rehabilitation of semi-collective wastewater treatment plants and the construction of new ones in the city of Yaoundé are timely, in a context of general insalubrity. However, the technologies of Yaoundé’s stations are still unknown and difficult to master, causing often, damage to the environment like pollution. The studies carried out, demonstrate risks of chronic toxicities, because the excess of individual risk (EIR) are all superior to 1.10^-6 per person per year for the employees who mainly deal with the tasks of managing the sludge and the screening in the enclosure. This demonstrates a probabilistic appearance of cancers in these employees. In order to put in place an integrated risk management plan for all future stations, the concerns of local residents and wastewater treatment plant(WWTP) staff have been taken into considerations. Through the surveys carried out, it has been observed that more than 70% of the people interviewed do not know the role of the wastewater treatmentplan (WWTP) and more than 48% of the same population make poor waste management in toilets. In addition, the method of analysis of system malfunctions (MASM) and a method of scientific analysis, risk assessment, highlight sludge as the main source of danger and people as the main target source. Moreover, the physic-chemical analyzes made at the entrance and at the exit of the purification stations confirms the high risk that the surrounding population run. The process of collection of wastewater up to the purification plants presents several dysfunctions. So the results of the water samples analyzed at the exit of the treatment plants after treatment could be better. As well as before and after the outlet, we confirm the pollution of the watercourse connecting to the water leaving the stations; It should also be noted that this pollution also attacks underground flows, the surrounding wells, because people complain of diseases caused by the water they use. These results enable the implementation of an Environmental and Social Management Plan (ESMP) that does not exist in the various treatment plants studied.
