The reprise of the spear. 1
\"Summoned to another world to serve as the Spear Hero, Motoyasu Kitamura is a pitiful young man who eventually finds himself only able to love filolials. But after being fatally injured in battle, Motoyasu wakes up yet again in the exact circumstances of when he was first summoned. It turns out that his spear possesses an ability known as Time Reversal! With his stats unaffected by the reset, Motoyasu decides to fight once more. His motivation: to once again see the smile of Filo, the filolial that he loves more than any other! Could this be considered the start of a new game in god mode?! The long-awaited otherworldly redemption fantasy begins!\"--Page 4 of cover.

Flawless polyaniline coating for preservation and corrosion protection of ancient steel spearheads: an archaeological study from military museum, Al-Qala, Egypt
The purpose of this research was to examine the viability of applying a flawless polyaniline coating on steel spearheads to preserve them and protect them from corrosion. The spearpoints, thought to be archaeologically significant, were acquired from the Military Museum in Al-Qala, Egypt. X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy were used to characterize the spearheads chemical composition and microstructure (EDX). The spearheads were determined to be constructed of steel and to have a coating of ferric oxide and other corrosion products on their exteriors. After that, a flawless polyaniline coating was electrochemically deposited onto the spearpoints in a way that was both quick and cheap. Many types of corrosion tests, such as electrochemical impedance spectroscopy and potentiodynamic polarization (PDP) readings, were used to determine the coating's effectiveness. The steel spearheads' findings revealed a significant improvement in their resistance to corrosion after being coated with flawless polyaniline. The coating served as a barrier, blocking out water and other corrosive substances and slowing the buildup of corrosion byproducts on the spearpoints. In conclusion, our research shows that a flawless polyaniline coating may be an effective anti-corrosion treatment for ancient steel artifacts. The approach is straightforward, cheap, and readily scalable for massive conservation efforts.

The Tip Cross-sectional Area (TCSA) Method Strengthened and Constrained with Ethno-historical Material from Sub-Saharan Africa
Work on large samples of southern African archaeological lithics, probably used to tip hunting weapons amongst other things, and ethno-historical bone and iron weapon tips of known use exposed limitations in the tip cross-sectional area (TCSA) method’s robustness for hypothesising about variation in ancient weapon-delivery systems. Here, we list some of the limitations and discuss a few recently published improvements in tip cross-sectional area ranges and data presentation. Our main contribution is the meaningful enlargement of datasets obtained from hafted weapon tips and/or weapon tips of known use mostly from sub-Saharan Africa. We briefly discuss why this region is relevant for studying trends in the evolution and development of hunting weapons. Our new data are used to strengthen and constrain the different TCSA ranges used as proxies for poisoned arrow tips, un-poisoned arrow tips, javelin tips, stabbing-spear tips, and to suggest a working TCSA range for thrusting-spear tips. We demonstrate that the calibrated TCSA ranges have robust statistical integrity as proxies for the different weapon-delivery systems they represent. Apart from the dart-tip category, the TCSA method has now been improved to accommodate more nuanced and accurate interpretations, while further strengthening hypothesis building about ancient weapon systems.
