Authors: Lombard Marlize , Churchill Steven
Published: April 2022

≠Gi was excavated almost half-a-century ago. Despite no formally published analyses of its lithic and faunal assemblages, the site has been important to discussions about technological development during the Middle Stone Age (MSA). Dating to ~77 ka, ≠Gi has been pitched as one of the earliest contexts in southern Africa where the spearthrower-and-dart may have been used as a mechanically projected weapon system. Here we provide a brief history of lithic-point research pertaining to the site, and report on a tip cross-sectional area (TCSA) analysis conducted on 359 Middle Stone Age points excavated from ≠Gi. Based on the TCSA approach, we hypothesise that the use of stabbing spears in ambush hunting, perhaps in tandem with lightweight javelin hunting, was the most likely scenario for the MSA hunters who used the site.

Published: April 2022

Este estudo teve como objetivo avaliar o potencial de um biorreator de membrana (MBR) piloto para a remoção de agrotóxicos, de formas individual e aliada com o uso de carvão ativado em pó (CAP). A estabilidade do MBR foi monitorada por meio dos parâmetros DQO, pH, SST e permeabilidade. A adição de agrotóxicos foi programada para gerar concentrações de 20 µg.L-1 de 2,4-D, carbendazim e diuron e 1,5 µg.L-1 de atrazina no biorreator. A remoção de agrotóxicos pelo MBR foi avaliada mediante quatro experimentos com variações de TDH (20 e 25 h) e adição de 0,5 g.L-1 de CAP. O MBR demonstrou robustez e estabilidade ao manter a qualidade do permeado mesmo sob elevadas variações de DQO e teor de biomassa. Contudo, promoveu apenas uma remoção parcial dos agrotóxicos estudados. O CAP otimizou a eficácia do sistema; no entanto, foi observada uma perda gradual das eficiências com o tempo, o que destaca a necessidade de mais estudos acerca da duração e da confiabilidade deste material.

To explore the seabed as well as the depth, to perform the various tasks in an underwater environment, to study the behavior of aquatic animals many researchers and scientists have developed underwater autonomous vehicles using different techniques. After going through all the robotic fishes developed in the last decade, we have developed a novel way and technique to enhance the speed of the robotic fishes under a certain range (30-40cm) of robotic body length. A crank-slotted slider and lever mechanism-based mechanism and fin have been designed to produce a forward thrust up to 25gmf. In the above system, the rotational motion produced by the DC motor is translated to oscillatory motion using a crank-slotted slider mechanism. The mechanical advantage is enhanced by the use of a certain length of the lever. Finally, for the given system a mathematical fin formula is introduced, tested, and implemented.

This work presents experimental investigations and parametric optimization during micro-Electric discharge Machining (EDM) drilling of Titanium alloy Ti-5.6Al-3.6V. The experiments have been designed by response surface methodology (RSM) based central composite design (CCD) taking current, pulse-on-time and pulse-off-time as input parameters; and drill rate and tool wear ratio as performance measures. After carrying out experiments, the effect of each input parameter on performance measures has been found. In order to study the microstructure of machined surface, scanning electronic microscope (SEM) has been performed. Single objective and multi-objective optimization have been done using artificial bee colony (ABC) algorithm to find the optimal combination of input parameters for the best yield of the process. Experimental verification of the obtained results has also been performed and a difference of less than 5% has been observed between experimental values and that obtained using ABC algorithm.

Suitability of material comes forth in deciding for the right material together with the shape and size of the dynamometer to support the cutting load. Role of material strength with the size of dynamometer came into decision when fixing the maximum cutting load on the assembly parts in the same way as role of shape of deforming element came into decision when setting up the maximum permissible deformation taken up by the dynamometer. Present work aims at verifying the selection of the size, shape and material under a target cutting load that are used by various researchers in designing the cutting dynamometers successfully. Research has been done to devise cutting dynamometers with varying shapes and sizes of deforming elements made with different materials. SOLIDWORKS is employed to model the material deformation and study is conducted to compare the values obtained for the maximum deflection, strain and total von-Mises stress developed at the most heavily stressed point through SOLIDWORKS with the corresponding theoretical or experimental values obtained by the researchers.

Penyebaran sindrom pernafasan virus corona (COVID-19) tidak sekadar menimbulkan implikasi di bidang kesehatan semata tetapi juga perekonomian secara global. Salah satu sektorusaha yang terkena dampak pandemi ini adalah Usaha Mikro, Kecil, dan Menengah (UMKM). Dampak dari pandemic COVID-19 yang menghantam UMKM adalah sebanyak 163.713pelaku usaha mikro kecil menengah, diantaranya usaha makanan dan minuman serta industri kreatif dan pertanian. Tujuan dari pelaksanaan penelitian ini adalah menyusun strategipengembangan Transformasi Digital yang dapat diterima oleh UMKM dengan menerapkan pendekatan Business Model Innovation, sehingga dengan pengembangan strategi tersebutdapat melihat permasalahan yang ada dengan melakukan pengembangan konsep yang dapat dibutuhkan bagi UMKM agar dapat beradaptasi dengan segala kondisi yang ada serta memiliki nilai daya saing dan dapat berkelanjutan sesuai dengan tuntutan saat ini agar memiliki keunggulan kompetitif. Transformasi digital digunakan untuk melakukan perubahan strategi bisnis yang dilakukan oleh para pelaku usaha, seperti UMKM. Produk digitalisasi yang merupakan strategi pengembangan dunia usaha UMKM, dapat dikembangkan lebih lanjut dengan bersinergi pada Business Model Innovation agar UMKM tersebut dapat beradaptif dan memiliki nilai daya saing lebih daripada lainnya. Kolaborasi keduanya tersebut dapat dilakukan dengan cara melakukan Value Creation, Value Delivery, dan Value Capture. Penerapan Business Model Innovation pada UMKM akan membantu pengembangan usaha guna meningkatkan nilai ekonomi dari masing-masing UMKM serta model bisnis ini dapat digunakan UMKM dalam menghadapi tantangan bisnis kedepan. Untuk dapat menjalankanstrategi pengembangan, dibutuhkan suatu Roadmap yang dapat menjelaskan proses digital transformation yang akan berkolaborasi dengan Business Model Innovation. Roadmap tersebut akan digunakan oleh para UMKM untuk menyelaraskan proses transformasi agar berjalan dengan konsep model bisnis yang dikembangkan. Agar hal tersebut dapat berjalan secaraberiringan, dibutuhkan suatu pengungkit (Enabler) yang dapat menjalankan pelaksanaan digital transformation pada model bisnis yang telah dikembangkan.
Pathways of CSR Perceptions of Employees: A Systematic Review
Authors: Özgoren Çagla
Published: April 2022

In this study, a systematic review of the literature on CSR-employee intersection, with a particular focus on perceived CSR from 2000 onwards, is provided. What is known about individual level antecedents of CSR perceptions, consequences for employees, with underlying mechanisms and contingencies, as well as theoretical orientations are consolidated in an integrated framework. New areas of investigation, where evidence remain inconclusive, are documented. These areas for research include the role of national/cultural context as contingencies in understanding perceived CSR, adaption of theories from diverse disciplines such sociology, in particularly, in linking micro-macro foundations of CSR, creative and pro-active behaviours of employees that are shaped by perceived CSR, with underlying mechanisms, as well as individual level antecedents of perceived CSR, among others. This review study contributes to the micro-foundations of CSR research through providing comprehensive and integrated picture on dynamics of CSR-employee research and concrete suggestions for future studies.

Bantengan in the Dutch colonial period in 1927 Claket, Mojokerto, East Java. The beginning of the formation of bantengan art begins with the establishment of martial arts whose originator named Mbah Siran. Before the existence of bantengan, Mbah Siran only trained pencak silat in the claket forest. Based on the discovery of a dead bull in the foot forest of Mount Welirang which was eventually dubbed the dead bull forest. From there it was also called Bantengan Art. Pencak silat in that year was actually not allowed by the invaders who were then colonized by the Dutch, did not abstain until there Mbah Siran and several students learned silat art silently in the forest at the foot of Mount Welirang which was to expel the invaders. When he found the dead bull, Siran got advice to take the bull's head and used it as a symbol of the bull which was also used to perform the bull's art, the bull's head was given the spirit of a dead bull to add to the attraction of bull art. The function of the banteng art in the following years is to enliven the organization such as weddings, circumcision, and other events. Bantengan art from mbah siran was named tri singly which means 3 musical instruments consisting of drums, saron, demung made into an art. However, because of this art, there is no written evidence at the present time due to damage eaten by insects and finally burned by the descendants of the second mbah siran named pak takiyat. which impact at this time is a struggle for many local and foreign parties including Malaysia.This is the cause of our burning enthusiasm to uphold the cultural values that exist in Mojokerto regency so that it can be preserved.
