Low repetition-rate, high-resolution femtosecond transmission electron microscopy
Authors: Flannigan David J. , Curtis Wyatt A. , VandenBussche Elisah J. , Zhang Yichao 
Published: October 2022

The spatial and energy resolutions of state-of-the-art transmission electron microscopes (TEMs) have surpassed 50 pm and 5 meV. However, with respect to the time domain, even the fastest detectors combined with the brightest sources may only be able to reach the microsecond timescale. Thus, conventional methods are incapable of resolving the myriad fundamental ultrafast (i.e., attosecond to picosecond) atomic-scale dynamics. The successful demonstration of femtosecond (fs) laser-based (LB) ultrafast electron microscopy (UEM) nearly 20 years ago provided a means to span this nearly 10-order-of-magnitude temporal gap. While nanometer-picosecond UEM studies of dynamics are now well established, ultrafast Å-scale imaging has gone largely unrealized. Further, while instrument development has rightly been an emphasis, and while new modalities and uses of pulsed-beam TEM continue to emerge, the overall chemical and materials application space has been only modestly explored to date. In this Perspective, we argue that these apparent shortfalls can be attributed to a simple lack of data and detail. We speculate that present work and continued growth of the field will ultimately lead to the realization that Å-scale fs dynamics can indeed be imaged with minimally modified UEM instrumentation and with repetition rates (frep) below—and perhaps even well below—1 MHz. We further argue that the use of low frep, whether for LB UEM or for chopped/bunched beams, significantly expands the accessible application space. This calls for systematically establishing modality-specific limits so that especially promising technologies can be pursued, thus, ultimately facilitating broader adoption as individual instrument capabilities expand.
The extent and protection of Australia’s deep sea
Authors: Bond Todd , Jamieson Alan 
Published: October 2022

Context Australia has the third largest exclusive economic zone in the world, but little is known about its deepest parts because, historically, research has focussed on coast regions or in the top 1000 m. Aim We aim to identify the extent of Australia’s deep sea, the deepest locations in Australian waters, and investigate how much of Australia’s deep sea is located within marine parks. Methods We use altimetry-derived water depth to calculate the total area in 1000-m bins. Key results The total area of Australian waters, excluding Antarctic waters, is 8 914 134 km2, of which, 70.4% is deep sea greater than 1000 m and 48% is deeper than the 3000-m abyssal boundary. In total, 56% of Australian Marine Parks are deeper than 3000 m and 20 of 61 marine reserves include water deeper than 5000 m. Conclusions The Convention on Biological Diversity calls for marine protected areas globally to increase from 7.7 to 30% by 2030: Australia has already placed over 40% of its waters under protection. Despite this, there are no long-term programs monitoring the deep sea and Australia has not produced a globally significant amount of deep-sea science. Implications Herein lies opportunities for Australia to understand fully its largest habitat and become the global exemplar of deep-sea science and conservation.

Published: October 2022

Abstract
IFAE is engaged in the production of linear triplet modules for the forthcoming upgrade of the Inner Tracker for the high luminosity phase of the Large Hadron Collider. The pre-production process requires the fabrication of early prototypes (the RD53A chip) to inform the assembly and electrical test methodologies. Module prototypes (also called triplets) include a set of 3 hybrids (sensors connected to readout chips), all of them are mounted in an individual flexible PCB. This document presents the assembly methodologies and main electrical tests results for the first set of 4 modules assembled at IFAE.
Mapping the Site of Biological and Ecological Interest of Rganat-Bouchkal (Tsili) Argan forest (Moroccan Central Plateau) using remote sensing
Authors: Sahel Y , Dellahi Y , Chahhou D 
Published: October 2022

Abstract
This work aims at developing a precise map of the distribution of Argan tree within Rganat-Bouchkal (Tsili) site which is considered as Sites of Biological and Ecological Interest (SBEI) with high biogeographic value. The methodological approach is based on the use of PLEIADES satellite image with a very high spatial resolution of 0.5m. A supervised classification was performed to develop an original map of the distribution of the Argan tree and the other accompanying species. The numerical method was also adopted to highlight the different factors influencing the distribution and the stat of the Rganat-Bouchkal (Tsili) SBEI stand. The results of this classification made it possible to map more than 770 feet of Argan trees located mainly on the slopes oriented South and South-East, on steepest slopes. The numerical method shows that the exposure factor and the edaphic factor explain mainly the distribution of SBEI species. Small stand either in the form of clumps or isolated feet, the Argan tree of Rganat-Bouchkal (Tsili) appears in a very degraded state, translating a massive exploitation of the tree cover and shrubby by the local population (example: abusive cutting and overgrazing).
Structural and Mining Geology of a Copper site with Epigenetic-type auriferous levels in the region of Imi Nisk in M’goun, Central High Atlas, Rural town of Abachkou, Azilal. Morocco

Published: October 2022

Abstract
Our initial intention was to use point geochemical data in relation to regional and/or local geology to identify and quantify the mineral potential of these Paleozoic formations, and the nature of the soil in relation to weathering by external climatic agents. The mineralogical study of the substrates proved to be essential to confirm the results of the spot sampling by channel sampling of the mineralized structures. From there, it was decided to focus on structural geology, regional tectonics, geochemistry, geomorphology, and the extension of veins from other deposits around this site. Because it is located at the Ordovician-Devonian contact, the copper mineralization at the future Imi Nisk mine site in the Central High Atlas has been interpreted in terms of sulfides-rich cluster deposits (Chalcopyrite, Azurite and Covellite) in Ankerite or siderite, and quartzite. The new structural and mineralogical data presented in this work favor the hypothesis of epigenetic mineralization, meaning that it was formed after the host rock. The present work consists in establishing a preliminary research in order to give a general idea and a very precise overview of the gitology, geology and geochemistry of the mineralized structures and veins located in this research permit in mining exploration of Imi Nisk. Also, no study has been published in this thematic on this site.

Published: October 2022

Abstract
The objective of the present study is to shed light on the parasitic load characterization of wastewater samples collected from four selected stations (O1, O2, O3 and O4 selected from upstream to downstream, on the bed of the Ouislane River in central Morocco. Parasite load flux (quantitative and qualitative) was determined monthly for one year, from January through December 2017, using direct spawning examination, the modified Bailenger concentration technique and the Faust flotation technique. Parasitological examination allowed the identification of helminth eggs and protozoan cysts, on the one hand, and the evaluation of the variation in the concentration of the parasitic load of this wastewater, on the other hand. The results of the present work allow the identification of 17 taxa: Ascaris lumbricoïdes, Trichuris trichiura, Capillaria sp, Ancylostoma diudinal, Enterobius vermicularis, Toxocara canis, Strongyloïdes stercolaris, Hymenolepis nana, Hymenolepis diminuta, Taenia saginata, Fasciola hépatica, Giardia lamblia, Entamoeba coli, Entamoeba histolytica, Blastocystis hominis, Balantidium coli and Cryptosporidium parvum. with a predominance of protozoan cysts over helminths eggs. The evolution of the parasitic load over time indicates the ubiquity of these parasitic species in raw wastewater at variable concentrations, which are closely related to the periods of human activities and according to the seasons. However, the high load of these intestinal parasites in the urban waters of Ouislane wadi will have a potential impact on human and livestock health. Hence the interest to prohibit their use commonly observed in the field and their practice in agriculture.

Published: October 2022

Abstract
Mass displacement to refugee camps often happens after an earthquake hits. Faecal oral transmission usually occurs causing disease outbreaks when people in mass displacement camps. Surabaya has a potential threat of an earthquake measuring 6.5 on the Richter Scale. However, equipment readiness in wastewater infrastructure is still low at 21% during the emergency response period. Therefore, this research is needed in formulating the concept of emergency wastewater infrastructure provision to minimize the side effects of disease outbreaks. This study obtained primary data from 17 respondents. The first objective uses content analysis method. Then the second objective adopted triangulation analysis derived from three types of data, respondent opinions, policies, and best practices. The first objective disclosed 46 criteria for the provision of emergency wastewater infrastructure. Meanwhile, the second objective presented 38 potential actions and 18 concepts adjusted to disaster management cycle (mitigation, preparedness, response, and recovery). The mitigation phase focuses on stocktaking materials, establishing partnerships, training for volunteers, and optimizing the existing sanitation program. The preparedness focuses on forming a team to assess the needs of post-disaster conditions. The response phases divided into acute, general, and stabilization. The general stage focuses on determining suitable infrastructure, mobilizing volunteers and materials, and coordinating between agencies or clusters to handle wastewater. The acute stage focuses on rapid assessment and procurement of materials. The stabilization stage focuses on community involvement, determining the location of infrastructure, and handling waste from wastewater treatment. Finally, the recovery phase focuses on repairing the existing affected wastewater treatment plant.

Published: October 2022

AbstractCoastal areas are one of the essential regions for the ecosystem. Consequently, monitoring and detecting the changes of coastal areas is thus necessary in order to provide valuable information for future mitigation and adaptation. Recently, the utilization of satellite images for coastal areas has been used widely and effectively as a viable alternative to in-situ observation and monitoring. In this study, multi-temporal satellite imagery data from Sentinel-2 have been used to find out the changes in the coastal area of Gianyar and Klungkung Regency - Bali, considering the capability which has good resolution with a wide swath and high revisit time. Sentinel-2 imagery data taken from 2016 and 2019 at an interval of about 4 years were collected to determine coastline changes. There are two main steps to detect the coastline. First is image classification by supervised classification where each pixel has been labeled with one or three classes. And the second is to make border segmentation between sand and water by applying the Modified Normalized Difference Water Index (MNDWI). The areas that are experiencing erosion and accretion were determined by using the overlay method between two satellite images. Results show that about 9,248 m2of coastline were eroded in Gianyar Regency and 121,000 m2in Klungkung Regency for the period of 2016 to 2019. Meanwhile, the accretion area reached 158,615 m2in Gianyar and 32,159 m2in Klungkung Regency.

Authors: Sugianto Erik , Chen Jeng-Horng , Sugiono Rohman , Prasutiyon Hadi 
Published: October 2022

Abstract
This study, the portable conveyor placement of ocean waste collection ships was numerically investigated by using computational fluid dynamics. Monohull ship models with different conveyor location variations are namely at the bow of the ship, on both sides of the ship, and on the bow and both sides of the ship. The three indicators used to assess ships in collecting ocean waste are flow patterns that indicate whether or not ocean waste is easy to get in closer to the conveyor, velocity contours that indicate whether or not ocean waste is approaching the conveyor fast, and ship resistance that affects fuel consumption. The results show that the conveyor on the bow model is the easiest to get the ocean waste closer to the conveyor. This model also produces the smallest ship resistance compared to other models. While the conveyor model on the bow and both sides is the fastest to make the waste approach the conveyor. This model also makes ocean waste that is not caught on the conveyor of the front ship can be caught by the conveyor on the side of the ship. However, this model produces the largest ship resistance compared to other models.

Published: October 2022

Abstract
Systems based on inverted theory pendulum are among the most difficult to adjust due to its instability. However, human body balances this type of system daily, from simple movements to the most complex. This paper present a type of biomechanical analysis of human gait using inverted pendulum theory. In the introduction are presented general notions used for the analysis of gait and bipodal mechanism. The next chapter presents reverse pendulum theory by means of a simple application, that of a trolley and a pendulum which seeks its equilibrium position when a force is applied on the trolley. By the action of the force, the pendulum finds its equilibrium position but which disappears when the cart stopped. Chapter three presents the experimental application of gait analysis using static images. The last chapter represents the conclusions of this type of analysis.

Abstract
In industrial engineering practice, the use of cutting tools, or those of plastic deformation (dies), is known, involves high costs of materials, and requires, at the same time, conditions of high resistance to deformation. The reduction of the mass of the parts, ie the reduction of the costs with the materials, from the composition of the tools, at the same time with the constant maintenance, or, if possible, with the increase of the rigidity, which, in turn, is identical with the decrease of the metallic materials. when trying to optimize the shape of mechanical parts. To evaluate and to study the behavior of a plate material, also, elastic deformation of a tool component part, a specialized Computer Aided Engineering (CAE) software, Ansys Academic R22, was used. The load was applied to the holes contour of the plate to simulate “action” which determines the generation of permanent plate deformation.The boundary conditions, i.e. the fixed supports, are materialized in the lateral face of the piece and the upper edge of the opposite face. Both the applied load and the limit conditions simulate real situations from industrial practice.

Published: October 2022

Abstract
With the increase in energy demand, the necessity for photovoltaic panels to be as efficient as possible has also increased. In order to achieve the highest possible performance, solar cells depend on a number of environmental elements such as: temperature, shading, cloudy weather, deposits on the surface, dust, solar irradiation, nighttime darkness, etc. All these factors ultimately result in a decline in photovoltaic panels performances. With the help of modeling and simulation programs, complex systems with high performance can be designed and realized, considering the advantage of avoiding manufacturing costs through their physical testing. Based on the electrical and thermal characteristics extracted from the Sanyo producer's data sheet, the proposed commercial photovoltaic module HIT-240HDE4, is implemented in the MATLAB environment under standard and real test conditions. The article presents the modeling and simulation in the MATLAB program of the proposed photovoltaic module, for the analysis of the electrical performances under the described conditions. Also, the article addresses the analysis issue of the operation considering the chosen module, under the same conditions.
