History of biological, mechanistic, and clinical understanding of concussion
Authors: Eaton Ryan G. , Lonser Russell R.
Published: July 2024

The history behind the biological, mechanistic, and clinical insights into concussion provides awareness of the current understanding and future areas for study. Although the initial description of concussion appeared in the 10th century, the potential long-term structural consequences were first defined by Harrison Martland, M.D., who performed a postmortem study of former boxers in 1928. He found evidence of perivascular microhemorrhage that he believed eventually evolved into a "replacement gliosis" underlying a clinical syndrome that he named "punch drunk," which was characterized by acute confusion with chronic cognitive and physical symptoms developing in those with prolonged exposure. Further research into the potential long-term consequences of repetitive concussions, particularly in athletics and the military, led to an understanding of chronic traumatic encephalopathy. To ameliorate possible long-term risks, research has been focused on preventative and therapeutic measures for concussion. In this review article, the authors present the history of concussion and the long-term sequelae of repeated head injury. Specifically, they consider how the understanding of concussion has evolved from antiquity into the modern era, and how this change in understanding of head injury has led to an appreciation of the fact that its long-term implications sometimes manifest as the clinical and histopathological entity of chronic traumatic encephalopathy.

Reakcje bernardynów na kasaty ich klasztorów w końcu XVIII i w XIX wieku – wybrane przykłady
Authors: Sitnik OFM Aleksander Krzysztof
Published: July 2024

W 1772 roku najwięcej klasztorów posiadała bernardyńska prowincja wielkopolska (37), następnie litewska (31), ruska (30) i małopolska (20). W sumie liczyły one 2359 zakonników. Z biegiem czasu wszystkie konwenty znalazły się w granicach państw zaborczych. W okresie kasat bernardyni stosowali różne strategie, aby ocalić istniejące klasztory i prowincje przed zniesieniem oraz zachować swój modus vivendi. Należały do nich: wykorzystywanie znajomości z urzędnikami państwowymi do ocalenia klasztorów skasowanych, prowadzenie przyklasztornych parafii, otwieranie szkół przyklasztornych dla młodzieży, próby zachowania przez prowincjałów i gwardianów pozytywnych stosunków z władzami zaborczymi, podporządkowywanie się nowym zarządzeniom władz państwowych, troska o nowicjaty, formację i studia, oddawanie się pod opiekę biskupom diecezjalnym, emigracja, starania prowincjałów u biskupów o nieprzyjmowanie do diecezji zakonników chcących się sekularyzować. Dzięki temu bernardyni ocalili swój modus vivendi, choć nie uchronili większości klasztorów przed kasatą. W 1900 roku, po zjednoczeniu z reformatami, funkcjonowała już tylko jedna zakonna prowincja galicyjska pw. Niepokalanego Poczęcia Najświętszej Maryi Panny. Liczyła jedynie 323 zakonników i 28 klasztorów. Stwarzała ona jednak podstawy do dalszego rozwoju bernardynów w wolnej Polsce.
Rubrycele i schematyzmy diecezji lubelskiej w okresie międzywojennym
Authors: Marczewski ks. Jarosław R.
Published: July 2024

Publikowanie rubrycel i schematyzmów w diecezji lubelskiej było standardem od początku istnienia tej struktury, a więc od pierwszej dekady XIX stulecia. Zewnętrzny kształt i porządek wydawniczy czerpał wzorce z tego rodzaju druków ukazujących się w diecezji chełmskiej, której spadkobierczynią była następnie diecezja lubelska. W okresie rozbiorów zarówno rubrycele, jak i schematyzmy ukazywały się niemal corocznie. W wyniku kwerendy udało się ustalić, że w dobie międzywojennej czyniono to już bez żadnych uchybień. Stosunkowo łatwo dostępne dzisiaj publikacje z lat 1919-1939 są zgromadzone w komplecie w kilku lubelskich bibliotekach i archiwach, ale także upowszechnione w formie online dzięki podjętej inicjatywie ich cyfryzacji. Rubrycele i schematyzmy lubelskie wydawane były wyłącznie w Lublinie. Posługiwano się w nich językiem łacińskim i polskim. W rubrycelach publikowano przede wszystkim kalendarz liturgiczny, ale także szereg innych informacji odnoszących się do sprawowania kultu, jak również niektóre częściej używane modlitwy. W schematyzmach zamieszczano przydatne w pracy kurii biskupiej i urzędów parafialnych informacje o instytucjach i duchowieństwie diecezji lubelskiej. Niezależnie od rzetelnej bazy zasobów Archiwum Archidiecezjalnego Lubelskiego, umożliwiającej pogłębione studia nad lubelską organizacją kościelną i jej życiem religijnym, rubrycele i schematyzmy pozostają ważnymi publikacjami źródłowymi, a zarazem ciekawymi obiektami badań.

Historycy interesują się m.in. jego dokonaniami jako prefekta Tajnego Archiwum Watykańskiego oraz działalnością jako nuncjusza w Warszawie i Wiedniu. W artykule przypomniano główne wątki badań związanych z życiem i dorobkiem naukowym Garampiego, szczególnie w okresie nuncjatury warszawskiej w latach 1772-1776. Jego pobyt w Warszawie jako nuncjusza apostolskiego pozwolił na organizację archiwum nuncjatury oraz ubogacenie jej obfitą dokumentacją dotyczącą historii Kościoła w Rzeczypospolitej. Garampi rozpoczął też systematyczne studia nad historią nuncjatury w Polsce, a zebrane przez siebie materiały opracowywał jeszcze po wyjeździe z Warszawy do Wiednia. Rozważania natury historiograficznej są wprowadzeniem do szczegółowego indeksu zawartości tomów 93-99 archiwum nuncjatury warszawskiej (Archivio Apostolico Vaticano, Arch. Nunz. Varsavia), zgromadzonych i uporządkowanych przez Garampiego. Oznaczone jako Miscellanee ecclesiastiche zawierają ważne materiały dotyczące m.in. jurysdykcji kościelnej i sporów w zakresie compositio inter status, ludności żydowskiej i procesów w sprawie oskarżeń o morderstwa rytualne, zamachu na Stanisława Augusta, Komisji Edukacji Narodowej i dyspens małżeńskich, żałoby po śmierci Klemensa XIV i wyboru Piusa VI, regulacji w sprawach postów i przestrzegania świąt nakazanych, spraw finansowych i podatków duchowieństwa, wreszcie spraw związanych z unitami.
ENHANCED MECHANICAL AND THERMAL PROPERTIES OF ELECTROSPUN CELLULOSE ACETATE FIBER MEMBRANES INCORPORATING PAHAE NATURAL ZEOLITE
Authors: Sihombing Y.A.
Published: July 2024

In recent decades, fiber membranes have garnered significant attention and found numerous applications across various fields. This work used the electrospinning method to create fiber membranes with cellulose acetate (CA) as a primary polymer material. The characteristics of the fiber membrane, such as mechanical and thermal properties, were investigated by incorporating Pahae Natural Zeolite (PNZ) microparticles into the CA matrix. The fiber membranes' mechanical properties are improved by adding PNZ to the CA matrix, and the CA/PNZ 10% exhibits the maximum tensile strength of 0.97 MPa and elongation at a break of 4.52%. Meanwhile, incorporating PNZ filler into CA fiber membranes significantly enhances their thermal stability. This improvement is attributed to the formation of hydrogen bonds between CA and PNZ, as evidenced by the increasing residue values with higher PNZ content. Specifically, the residue of pure CA membrane fiber is 13.46%, which increases to 44.06% for CA/PNZ 15% fiber membranes. These favorable thermal and mechanical properties of the fiber membranes indicate the promising potential of CA/PNZ based membranes for filtration applications.

Fractional-Order Total Variation Image Restoration Based on Alternating Direction Method of Multiplier Algorithm
Authors: Chen Fangfang , Hu Huashu , Tang Xingzhen
Published: July 2024

The application of computer image processing technology is more and more extensive, such as geological survey, disaster inspection, urban planning medical imaging, industry, agriculture, military and other fields. In the method of image denoising, the restoration model based on variational principle has been the focus of research in the field of digital image. In order to take into account the recovery of image edge and texture information and a more efficient optimization algorithm, a fractal-order total variational denoising method based on shearlet regularization terms is proposed in this paper. This model combines the advantages of fractional variational model and shear wave transform, which can not only effectively recover the edge and other details of the image, but also enhance the mid-frequency information of the image by using more adjacent pixel information, and retain the low-frequency component of the image nonlinearly. Thus, anisotropic features such as edges and curves of the image can be effectively preserved. In numerical calculation, by applying alternating direction method of multiplier (ADMM) to solve this model, we find that all ADMM subproblems have closed-form solutions. Finally, extensive experiments involving both denoising and texture extraction applications are employed to illustrate the validity of this model.

Authors: Zhan Zhiguo , Li Bo , Gao Jianxin
Published: July 2024

Existing transmission line monitoring has problems such as low intelligence, low efficiency, low flexibility, etc. The star-earth collaborative network specialized network has the ability to transmit large data in real time in remote, mountainous and other kinds of scenes. It can meet the transmission line area intelligent monitoring of high-definition video, images and other transmission requirements. It can solve the above problems in the process of transmission line monitoring. In view of this, we first study the functions and service characteristics of transmission line monitoring system to obtain the influencing factors of different service access users’ choices. Then, we establish the star-ground collaboration network architecture to satisfy the network scenario, and systematically model the star-ground collaboration network architecture. And then, we give the design idea of the star-ground collaboration network multiple access algorithm, and propose the deep learning-based star-ground collaboration network multiple access algorithm. The results of related simulation experiments show that our proposed multiple access algorithm is significantly better than the mainstream multiple access algorithm in terms of link resource utilization and system throughput.
Research on Trajectory Planning of Industrial Robot Based on MATLAB
Authors: Duan Chenxu , Wang Yifan , Kumari Saru
Published: July 2024

With the progress of industrial automation, industrial robots play an increasingly important role in the upgrading of the manufacturing industry. Trajectory planning is the key technology of precise motion control of industrial robots. At present, most industrial robots use the method of teaching programming for trajectory planning, which has the problems of low efficiency, long time-consuming and poor accuracy. Simulation programming overcomes many shortcomings of teaching programming. It uses information technology to program, debug and run in simulation scenarios, which reduces time costs and improves planning efficiency and accuracy. It has attracted more and more attention from manufacturing enterprises. In this paper, the trajectory planning process based on MATLAB platform is studied by taking GSK RB08A3 6-axis industrial robot as the research object. Firstly, the coordinate system of each link of RB08A3 robot is established according to the standard DH parameter method, and the mathematical model is built according to the parameters of the robot. The forward and inverse kinematics verification is completed by using the functions in the Robotics Toolbox of MATLAB, which further proves the correctness of the modeling. Then, the multi-trajectory planning problem of industrial robots in Cartesian space is studied. A continuous multi-path smooth transition algorithm is designed based on the improvement of S-shaped speed curve, and the simulation experiment is carried out on the MATLAB platform compared with the traditional S-shaped acceleration and deceleration algorithm with zero head and end speed. The results show that the execution efficiency of the algorithm is greatly improved compared with the traditional S-shaped speed curve trajectory planning, and the effect of smooth transition of adjacent trajectories is achieved, and the mechanical impact is also reduced. Finally, aiming at the problems of working efficiency, energy consumption and flexible impact during start-stop of industrial robots, a time-energy optimal 5-3-5 piecewise interpolation joint space trajectory planning method is proposed. The simulation results show that the optimized piecewise interpolation trajectory can effectively avoid the flexible impact during start-stop, greatly improve the working efficiency of industrial robots, greatly reduce energy consumption, and achieve the comprehensive optimization of time-energy consumption, which verifies the effectiveness of the trajectory planning method.

The early warning of electricity recovery risk needs to rely on a large number of data, including electricity consumption data, user information, historical arrears records, etc. However, the quality of these data may fluctuate and be unstable, which affects the accuracy and accuracy of the early warning model. Therefore, based on frequent item sets and big data, an active early-warning model of electricity bill recovery risk is constructed. Based on the power big data, the power rate recovery risk warning level constraints were determined, and the power rate recovery risk warning index weight was optimized. Considering frequent item set, the unified data model of electricity charge is constructed by distributed memory data grid technology. Through the fuzzy comprehensive evaluation, the electric charge recovery safety risk warning index is normalized to realize the active early warning of electricity charge recovery risk. The experimental results show that the model constructed in this study has a small deviation in active early warning of the risk of electricity bill recovery, and is practical.

Konstruksi Realitas Sosial Tafsir Al-Qur’an pada Unggahan @peachyfraise dalam Media Sosial X
Authors: Nugroho Ihsan , Efendi Erwan
Published: July 2024

Al-Qur’an is a text that teaches equality and justice between men and women, but the interpretations made by clerics and scholars throughout history are often considered to be influenced by their social and cultural context, which can create gender bias. This bias can occur in various aspects of life, including in the workplace, education, media, and everyday social interactions. In a media context, there was an interesting upload made by the @peachyfraise account on social media X which then received a debate response. This research aims to identify the social construction that occurs in one of the posts about the interpretation of the Al-Qur'an. This research uses a qualitative methodology by applying the social construction theory proposed by Peter L. Berger and Thomas Luchkmann. The findings of this research focus on how ready and able individuals are to face the modern world, where they must be able to make decisions regarding their attitudes based on their skills and abilities.

Published: July 2024

Salah satu parameter kimia dalam persyaratan kimia air bersih adalah kesadahan. Kesadahan merupakan  istilah yang digunakan pada air yang mengandung kation penyebab kesadahan dalam jumlah yang tinggi. Pada umumnya kesadahan disebabkan oleh adanya logam - logam atau katio - kation yang bervalensi 2, seperti Fe, Sr, Mn, Ca dan Mg. Tujuan penelitian ini adalah untuk mengetahaui efektivitas arang sekam padi dalam menurunkan kesadahan air sumur gali. Jenis penelitian ini adalah True Experimental dengan pretes-posttest design yaitu melihat penurunan kesadahan air sumur gali sebelum dan sesudah perlakuan dengan menggunakan kombinasi variasi ketebalan dan waktu kontak. Hasil penelitian menunjukkan rata - rata penurunan kesadahan air dengan variasi ketebalan media arang sekam padi dan waktu kontak. Dengan hasil yaitu pada ketebalan media 10 cm dengan waktu kontak 40 menit, 50 menit dan 60 menit diperoleh secara berturut - turut 617,5mg/l,  463,8 mg/l, dan 402 mg/l. Adapun pada ketebalan media 20 cm dengan waktu kontak 40 menit, 50 menit dan 60 menit secara berturut - turut diperoleh 434,2 mg/l, 424,7 mg/l, dan 312 mg/l. sedangkan pada ketebalan media 30 cm dengan waktu kontak 40 menit, 50 menit dan 60 menit secara berturut - turut diperoleh 208,5 mg/l, 136,4 mg/l, dan 120,3 mg/l. Kesimpulan dari penelitian ini adalah ketebalan media arang sekam padi 10 cm dengan waktu kontak 50 menit dikatakan efektif dalam menurunkan kesadahan air sumur gali memenuhi standar baku mutu yang diperbolehkan Permenkes RI No. 32 Tahun 2017 yaitu ≤ 500 mg/l. Sehingga dapat menjadi salah satu alternatif dalam menurunkan kesadahan karena bahan yang mudah dijangkau. Disarankan kepada peneliti selanjutnya agar menjadi bahan pertimbangan dalam memilih media arang sekam padi karena sifat fisik dari media yang ringan maka dapat dengan mudah mengapung sehinga diperlukan media lain sebagai penahan atau pemberat dalam proses penyaringan serta dalam pengaktivasian menggunakan bahan-bahan alternatif yang mudah dijangkau masyarakat.
