Regarding the South Caspian oil and gas province, it is concluded that the Pliocene productivity prevails in the western part of the province, and that the gas and oil prospects of the eastern land side in the Mesozoic are prioritized. A retrospective analytical review of geological and geophysical data and publications on the Mesozoic of Southwestern Turkmenistan was carried out, which showed the low efficiency of the performed seismic and drilling operations in the exploration and evaluation of very complex Mesozoic objects. A massive resumption of state-of-the-art seismic exploration and appraisal drilling in priority areas and facilities performed by leading Russian companies is proposed. For some areas, a new, increased estimate of the projected gas resources is given. An example of modern high-efficiency additional exploration of the East Cheleken, a small Pliocene gas and oil field, which turned this field into a large one in terms of reserves, is given.

INTRODUCTION: The results for the meta-analytical review, which contrasted laparoscopic or robotically assisted esophagectomy for cancer against open esophagectomy (OE), indicated feasibility and safety associated with the robotic method. AIM: The objective of this study is to review the current literature on MIE (Laparo-thoracoscopic and Robotic approach) and open approach and check the state-of-the-art of esophagectomy for cancer. MATERIALS AND METHODS: The comparison of studies which contrasted laparoscopic or robotically assisted esophagectomy for cancer against open esophagectomy (OE). RESULTS: This review represented the largest sequence of mini-invasive esophagectomy (MIE) to date and the results appear to be comparable to those attained by the traditional open approach. MIE constitutes a safe procedure with a learning curve of around 36 cases. CONCLUSION: The studies did not reveal variations in mortality and morbidity rate, conversion rate, intensive care unitstay, 1-month mortality, and post-operative complications between the mini-invasive esophagectomy cohort and OE cohort.

Image inpainting is the process of restoring missing pixels in digital images in a plausible way. A study on image inpainting technique has acquired a significant consideration in various regions, i.e. restoring the damaged and old documents, elimination of unwanted objects, cinematography, retouch applications, etc. Even though, limitations exist in the recovery process due to the establishment of certain artifacts in the restored image areas. To rectify these issues, more and more techniques have been established by different authors. This survey makes a critical analysis of diverse techniques regarding various image inpainting schemes. This paper goes under (i) Analyzing various image inpainting techniques that are contributed in different papers; (ii) Makes the comprehensive study regarding the performance measures and the corresponding maximum achievements in each contribution; (iii) Analytical review concerning the chronological review and various tools exploited in each of the reviewed works. Finally, the survey extends with the determination of various research issues and gaps that might be useful for the researchers to promote improved future works on image inpainting schemes.

This paper describes the latest advances in electric propulsion systems prepared for the new space exploration activity. Missions to the Moon and Mars will require these new thrusters to convey the huge amounts of provisions that would be expected to help changeless bases on other universes. The new advancements are likewise being utilized for unmanned investigation missions that will go to the furthest reaches of the nearby planetary group. This paper is expected to provide some insight into some ideas for electric propulsion - standards and work skills, as well as a diagram of mission applications that would benefit from these frame drives and their use with state-of-the-art control systems.

One of the most relevant issues beyond the effectiveness of etiological treatment of Chagas disease is the lack of consensual/feasible tools to identify and certify the definitive parasitological cure. Several methods of distinct natures (parasitological, serological, and molecular) have been continuously proposed and novel perspectives are currently under investigation. Although the simultaneous use of distinct tests may offer better contributions and advances, it also leads to controversies of interpretation, with lack of mutual consent of cure criterion amongst researchers and physicians. In fact, when distinct host compartments (blood/tissues) are evaluated and explored, novel questions may arise due to the nature and sensitivity limit of each test. This short analytical review intends to present a chronological and critical overview and discuss the state-of-the-art distinct devices available for posttherapeutic cure assessment in Chagas disease, their contributions, meanings, and interpretation, aiming to point out the major gaps and propose novel insight for future perspectives of posttherapeutic management of Chagas disease patients.
