The facades of a building can present more accelerated degradation than the internal parts of a building, as they are constantly exposed to the environment and atmospheric actions, leading to a deterioration throughout its useful life. In view of this, the present research aimed to carry out an inspection to evaluate the current situation of pathological manifestations found in the facades of block G of the Polytechnic School of Pernambuco and elaborate map of their damage. Bibliographical research was carried out through journal articles, books, dissertations and theses in order to address the pathological problems in facades and damage map. Due to the absence of facade plans of the chosen building, a measurement service was carried out using pocket tape and laser tape that served as the basis for the design of the same. Then, the construction of the facade designs was done using AutoCAD software. In addition, surveys were made on the 04 facades of the block that enabled the identification of their pathological manifestations, recorded through a Checklist. Finally, the damage map was created from the data obtained through AutoCAD. It was found that the most recurrent pathological problems were: dirt, cracks, vegetation and detachment of the painting. The damage map proved to be a fundamental tool for the registration of pathological manifestations of a building, as well as for the basis of use for future interventions and/or monitoring of the framework of preservation conditions.

The space launch vehicles are used to place satellites in the orbit. There are mainly three types of rocket engines classified on the basis of fuel i.e. solid, liquid and cryogenic. The performance of a rocket engine is generally analysed on four parameters namely pressure, temperature, density and velocity inside the system. A typical nuclear rocket engine operates on one of the thermodynamics cycle which vary in complexity and efficiency. The Nuclear Thermal Rocket (NTR) engines are expected to perform several times better in terms of efficiency in comparison to liquid/solid fuel engines. An NTR engine operates by using nuclear fission process to heat propellants to high temperature. The major limitation of NTR engines is the rate at which this energy can be extracted from the nuclear fuel and used for heating the propellants. This paper explores the efficiency, stability and other design challenges of a NTR engine.
