Authors: BULZAK Tomasz , PATER Zbigniew , TOMCZAK Janusz
Published: December 2022

The paper presents a new extrusion process for producing twist drills using split dies. The design of the dies is described, where the profile of the flute-forming element is the same as the profile of the flute on the plane inclined to the drill axis at an angle equal to the helix angle. The proposed method for the extrusion of twist drills by the new type of dies is verified by numerical modeling. Three cases of the extrusion process are modelled, each with a different position of the flute-forming element relative to the axis of the drill. The paper investigates the effect of the position of the flute-forming element on the angle of inclination of the flutes and the cross-section shape of the drill. Numerical modeling is performed using DEFORM-3D.

HIGH SPEED MILLING IN THIN-WALLED AIRCRAFT STRUCTURES
Authors: BAŁON Paweł , REJMAN Edward , SMUSZ Robert , SZOSTAK Janusz , KIEŁBASA Bartłomiej
Published: December 2022

Aircraft structures are designed to mainly consist of integral elements which have been produced by welding or riveting of component parts in technologies utilized earlier in the production process. Parts such as ribs, longitudinals, girders, frames, coverages of fuselage and wings can all be categorized as integral elements. These parts are assembled into larger assemblies after milling. The main aim of the utilized treatments, besides ensuring the functional criterion, is obtaining the best ratio of strength to construction weight. Using high milling speeds enables economical manufacturing of integral components by reducing machining time, but it also improves the quality of the machined surface. It is caused by the fact that cutting forces are significantly lower for high cutting speeds than for standard machining techniques.

Authors: Onozawa-Komatsuzaki Nobuko , Tsuchiya Daisuke , Inoue Shinichi , Kogo Atsushi , Ueno Toshiya , Murakami Takurou N.
Published: December 2022

Halogenated solvents (e.g. chlorobenzene and chloroform) are typically used for hole-transporting materials (HTMs) in perovskite solar cells (PSCs); however, their use should be avoided as they are known to be hazardous to the environment. Herein, we synthesized a nonhalogenated-solvent-soluble, dopant-free HTM, SF62. When depositing HTMs for PSCs, SF62 could be dissolved with a nonhalogenated and green solvent, ethyl acetate. It is one of the most common organic solvents and is known to have a low environmental impact. Non-doped-SF62-based PSCs exhibited higher power-conversion efficiency (18.6%) than doped 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamino)-9,9′-spirobifluorene (Spiro-OMeTAD)-based ones (18.3%), with enhanced stability.

Abstract: Purpose: The study examined the effects of the strategies employed by the Alliance for Democracy (AD), the main opposition party in the 1999 general elections in Nigeria, to manage its internal conflicts. Research methodology: This study is qualitative. It analyzed secondary data on Nigeria’s Fourth Republic to explain the management of intra-party conflicts in the Alliance for Democracy (AD). Results: It found that the AD was able to record remarkable successes in the 1998/1999 general elections as a result of its internal mechanism for mediation, bargaining, consultations, and negotiations among the party members. However, its inability to employ effective management strategies to settle internal crises before and after the 2003 general elections signaled the loss of its status as one of the leading parties in the country. Limitations: Despite being the main opposition party in the 1999 general elections, literature on the AD is scanty. This limited insights into events that culminated in the AD’s loss of status as a frontline political party in Nigeria. Contribution: It enriches the literature on the causes of intra-party conflicts and the effects of mismanaging such conflicts on party stability. It also provides deep insights into the reasons for AD’s loss of status from being the main opposition party in Nigeria between 1999 and 2003 to being deregistered in 2020.

MANET (Mobile Ad hoc Network) is an ad hoc network that may be constructed on demand. Due to its dynamic nature, it allows nodes in the network to communicate with each other without the use of any infrastructure. When compared to conventional wireless networks, MANET's on-demand setup makes it more popular. Conventional wireless networks require a central authority for overall system operations, while MANET is an infrastructure-less and self-organized network that is generally a wise choice when it comes to certain application areas like military operations, communication in natural disasters, man-made emergencies, rescue procedures, and vehicular ad hoc network (VANET) for sharing information among vehicles as well as providing traffic conditions and warnings. This new network, however, faces several challenges and difficulties, including compromised security, routing issues, cooperation, multicasting, power efficiency, IP addressing, QoS etc., that must be properly taken care of before it can be deployed in real-time. The current paper provides a full analysis of MANET, including its problems, concerns, and possible research topics, which will be very useful for academics who want to begin their work on this subject.
