Danish Finds of Mammoth (Mammuthus primigenius (Blumenbach)) Stratigraphical position, dating and evidence of Late Pleistocene environment
Authors: Aaris-Sørensen Kim , Petersen Kaj Strand , Tauber Henrik
Published: June 2021

A catalogue of all known remains of mammoth in Denmark is presented, comprising 125 finds. Half of the mammoth material is molars, which are morphologically referred to Mammuthus primigenius (Blumenbach), a third is tusk, and the rest is bone fragments. 14 specimens of mammoth have been C-14 dated. 13 samples have ages from older than 40 000 to ca 21500 C-14 years B.P., and one sample gave an age of ca 13200 C-14 years B.P. As the skeletal material is redeposited, these dates at the same time give maximum ages of the glacial deposits in which they are found. On the basis of this evidence the glacial development during the Weichselian is reviewed. An ice-free period from before 45000 B.P. to around 20 000 years B.P. is indicated. A mammoth tusk from the Tirstrup sandur on Djursland, dated to 13240 +760/-690 B.P., marks an important stage in the ice retreat in Denmark, and shows that the mammoth re-immigrates after the maximum expansion of the Weichselian ice. Remains of other Late Pleistocene vertebrates are also mentioned. On the basis of floral and faunal remains the environmental changes during the Late Pleistocene are then reconstructed. The ice-free period in the Middle Weichselian was characterized by a steppe biome, which may appropriately be termed the mammoth steppe. This Weichselian environment seems to be incomparable to any environment known today.

In June 1989, Dansk Olie- og Gasproduktion A/S (DOPAS) sponsored a well-attended symposium on the Jurassic in the Southern Central Trough held at the DOPAS premises in Hørsholm, Denmark. The background for the symposium was a desire among geologists working in the Dutch, German and Danish sectors of the North Sea to establish a forum to discuss problems of lithostratigraphic correlation across the sector boundaries and eventually arrive at a common nomenclature. A number of lectures were held at the symposium and an informal working group was established to deal with the details of lithostratigraphic correlation. The present publication, sponsored partly by DOPAS and partly by the Geological Survey of Denmark (DGU), contains extended abstracts of the lectures.

Bài báo này ước lượng tính bị chặn bền vững của hệ điều khiển ngẫu nhiên với xích Markovian rời rạc. Bằng cách sử dụng phương pháp hàm Lyapunov và lí thuyết xác suất, chúng tôi đề xuất một số điều kiện đủ mới để đảm bảo tính bị chặn bền vững cho hệ điều khiển ngẫu nhiên. Các điều kiện trên là các bất đẳng thức ma trận tuyến tính có thể kiểm tra và dễ dàng sử dụng trong thực tế. Thật không may mắn, có nhiều khó khăn nảy sinh khi nghiên cứu các hệ này khi chúng ta phải đối mặt với các quá trình ngẫu nhiên và nhiễu không mong muốn. Thêm vào đó, phương pháp hàm Lyapunov là một công cụ đầy hiệu quả khi nghiên cứu tính ổn định của các hệ phương trình vi phân. Tuy nhiên, phương pháp này không hiệu quả khi áp dụng cho các hệ ngẫu nhiên do chúng ta không biết làm thế nào để cấu trúc các hàm Lyapunov phù hợp và làm thế nào để sử dụng các hàm này cho các quá trình ngẫu nhiên. Để vượt qua các khó khăn trên, đầu tiên, chúng tôi giới thiệu các khái niệm cơ bản của lí thuyết ngẫu nhiên. Tiếp đó, chúng tôi thiết lập một điều kiện đủ mới về tính bị chặn bền vững cho hệ ngẫu nhiên không có điều khiển. Cuối cùng, kết quả này được áp dụng cho việc thiết kế điều khiển cho hệ ngẫu nhiên có điều khiển.

Authors: Hà Nguyễn Thị Hồng , Thảo Dương Thị
Published: June 2021

Khi mọi người nói hoặc viết, họ tạo ra văn bản. Đối với một nhà ngữ pháp, văn bản là một hiện tượng phong phú, nhiều mặt, có nghĩa theo nhiều cách khác nhau. Ngữ pháp chức năng hệ thống (SFG) là một loại ngữ pháp có thể mô tả việc sử dụng ngôn ngữ để hiểu ý nghĩa của văn bản. Việc áp dụng khung phân tích của SFG để phân tích một văn bản có thể tránh được việc đánh giá một cách chủ quan. Bài báo phân tích văn bản “A grandmother with muscles” dựa trên quan điểm ngữ pháp chức năng hệ thống của Mark Haliday về chuyển tác (transitivity), thức (mood) và cấu trúc đề - thuyết (theme-rheme). Kết quả nghiên cứu cho thấy văn bản có những đặc trưng của thể loại trần thuật, mang các đặc điểm sau: tồn tại chủ yếu quá trình vật chất (material process) và quan hệ (relational process), sử dụng quá khứ đơn và hiện tại đơn, đa phần là chủ thể cá nhân và thức chỉ định (declarative), ít động từ tình thái và hầu hết chủ đề thuộc thành tố tư tưởng (ideational component), chủ đề không được đánh dấu (unmarked theme).

Published: June 2021

Over time, the CAN (Controller Area Network) communication bus has been implemented in different technological sectors, within which, depending on the application, the bus implementation may change. On the other hand, the design and implementation of digital controls based on experimental data is a well-known topic in the automation industry where the acquisition system is of great importance. In this document, a heuristic study of the behavior of a Full CAN network is reported to implement digital controllers in two interconnected control loops. This study takes into account the access time to the bus and the amount of data sent when observing the response to disturbances. The design of two digital controllers is presented based on the parametric identification of two plants: a DC motor with an electromagnetic brake and a pneumatic levitator. Using PSoC® microcontrollers, a Full CAN network is implemented, where the digital controllers exchange data by randomly accessing the bus. A specially designed interface allows visualizing the speed and amount of data transferred under different operating conditions of the control loops. At the document end, the experimental data obtained are discussed.

Finally, are presented the defined strategies for aligning manufacturing to production.
Cost analysis in reverse logistics of grade 2 asparagus
Authors: Quintero-Ramírez Juan Manuel
Published: June 2021

This investigation makes observations in the reception of raw material, warehouse and production, to define the percentage of scrap or waste that is had. It is intended to solve these losses, since the percentage of waste adds up to 10%, financially affecting the volume of production of finished product and the costs of farmers who supply said raw material. The objective is to propose an economic valuation of grade 2 asparagus, which helps to reduce monetary losses for farmers and increase profits for the collecting company. Delivery quantities of five asparagus producers are recorded during the months of May to July that supplies the collector who selects and packs the final product. With cost analysis, a comparison is made of values such as incoming kilograms, kilograms usable for export, prices at which farmers are paid and the price at which it is intended to sell in the local market in addition to presenting monetary amounts of recovery to the apply reverse logistics in the company. The result obtained represents the loss of asparagus and a proposal for use is proposed to be sold and how much it would contribute per season when implementing this proposal.
Design of a rotational type vibration absorber
Authors: Vázquez-González Benjamín , Jiménez-Rabiela Homero , Ramírez-Cruz José Luis
Published: June 2021

Mechanical vibration absorbers are mechanical subsystems capable of developing an oscillatory movement, which dynamically compensates for the vibratory motion developed by a mechanical system of interest, which is affected by an action that can produce a movement that directly affects it in a non-desirable way. The system of interest is called the primary system and the absorber is called the secondary system. The way in which both systems interact establishes the conditions in which absorption will take place. Traditional absorbers are made up of systems coupled by means of an elastic element, they can also have viscous type coupling and very complex couplings can be presented by elastic and viscous type combinations. The objective of the present work is to design a rotational type vibration absorber, in which the interaction between both mechanical systems is developed by contact by rotation without sliding and elastic coupling. Euler-Lagrange equations are used to obtain the mathematical model of the system. One of the main characteristics of the rotary absorber is that the absorber can be designed to achieve small amplitudes of the displacement of its center of mass, but large displacements. Results are presented in numerical simulation.

Published: June 2021

The agricultural sector in Mexico is vulnerable to climatic variations and the happening of natural disasters. We analyze the Component of Attention to Agricultural Incidents (CADENA in Spanish) that is focused on small peasants with low incomes, and without access to insurance coverage and the Agricultural and Rural Insurance Funds. (FAAR) they operate under the logic of mutualism, so they only offer coverage to their partners. The geographic coverage of both mechanisms is differentiated; the FAAR concentrate their operation in regions with high commercial value agriculture and the CADENA operates throughout the country promoting incentives for contracting catastrophic insurances in municipalities with high and a very high degree of marginalization. It is concluded that both mechanisms complement each other as a public policy for agricultural risk management.

Learning strategies mediated by technology: students’ perception
Authors: Flores-González Efigenia , Flores-González Norma
Published: June 2021

Nowadays, the incorporation of technology in the educational field has transformed the scenario of the teaching-learning process, generating a change in the role of its actors, where it determines the vertices of the perfect triangulation between teachers, students, and content (Coll, 2011). Therefore, it is crucial to explore the virtual universe and implement technology-mediated learning strategies that promote the appropriation of knowledge and assess students' perceptions to contribute to new virtual teaching proposals. This research aims to explore the students' perceptions of the Regional Enrique Cabrera Barroso High School, BUAP, regarding the use of strategies applied in the Schoology platform to promote Biology learning. For this, a descriptive quantitative study was carried out in a focus group using a Likert-type scale questionnaire, obtaining the following results: the students demonstrated a high level of satisfaction with the virtual course evaluating virtual strategies as an ad hoc complement to achieve the learning objectives. They also stated that the assimilation and appropriation of knowledge depend on those technology-mediated strategies, contributing to a highly positive perception.

Information Asymmetry in the Post-IFRS Adoption Period: Evidence from Developing Countries
Authors: Juniarti Juniarti , Marcellina Beatrice , Angela Alvita
Published: June 2021

Objective - The adoption of IFRS aims to reduce the level of information asymmetry. Prior studies conducted in developed countries prove that the adoption of IFRS enhances transparency and diminishes information asymmetry. However, in developing countries with a low level of openness, limited regulation, and more centralized ownership, the ability of IFRS to reduce information asymmetry remains unknown. To address this issue, this study aims to investigate whether IFRS adoption will reduce information asymmetry in some developing countries in South East Asia.

Methodology/Technique - This research is applied in three developing countries: Indonesia, the Philippines and Thailand. Information asymmetry is proxied by the cost of capital using the Easton model (2004) and a bid-ask spread. Listed firms from the three countries are selected as the research sample resulting in 5.313 firm-years for the period between 2007 and 2016.

Findings - This study concludes that the adoption of the IFRS decreases information asymmetry in developing countries. These finding confirm that the benefit of the adoption is the same as in developed countries, despite the level of law enforcement in developing countries being lower. Managers, standard authorities and investors must note that the IFRS conveys benefits to the market, which increases transparency by asking lower returns and valuing company stocks appropriately.

Novelty - This study examines the benefits of the adoption of the IFRS in reducing information asymmetry in some emerging countries to enhance the generalization of the results from prior studies that are mostly conducted in developed countries.

Type of Paper Empirical

Keywords: Bid-ask Spread; Cost of Capital; Information Asymmetry; IFRS Adoption.

Published: June 2021

Produksi buah pisang di Desa Cerme, Kecamatan Juwangi, Kabupaten Boyolali sebesar 2700 kwintal per tahun (BPS, 2019). Angka ini merupakan terbanyak diantara desa lainnya di Kecamatan Juwangi. Namun hasil panen yang melimpah masih dijual oleh petani dalam bentuk segar saja tanpa ada proses penanganan yang baik. Padahal penanganan yang tidak benar dan tidak tepat dapat mengakibatkan kerusakan yang cukup tinggi karena sifat hasil pertanian yang mudah rusak terutama untuk golongan buah dan sayuran. Oleh karena itu, penyuluh pertanian di Balai Pertanian Juwangi mengadakan program SAOSANG (Desa Olah Pisang) yaitu pelatihan pengolahan pisang menjadi kripik pisang aneka rasa serta pemasarannya. Metode pendekatan yang diterapkan dalam program ini menggunakan metode ceramah, demonstrasi mengolah aneka kripik aneka rasa, seperti coklat, balado, keju, matcha serta metode tanya jawab. Kegiatan ini diikuti oleh 10 orang anggota kelompok tani Wonotirto berjalan dengan lancar. Hasil dari kegiatan ini menunjukkan peningkatan pengetahuan yang efektif (91%). Hal tersebut ditunjukkan pada hasil pre test 8,6 dan post test 22,7 dengan selisih 14,1. Selain itu, peserta juga antusias selama mengikuti kegiatan baik praktik maupun teori. Adanya program SAOSANG diharapkan menambah wawasan, pengetahuan dan keterampilan sehingga mampu membuka usaha baru rumahan yang potensial di Desa Cerme. Pada akhirnya peningkatan pengetahuan tersebut akan berdampak terhadap peningkatan kesejahteraan keluarga petani. Kegiatan pelaksanaan SAOSANG perlu dilaksanakan dan ditingkatkan untuk kelimpok-kelompok tani yang lain dengan media pembelajaran yang menarik dan efektif.

Judging the Judges
Authors: Munir Muhammad
Published: June 2021

This work attempts to analyze what precisely is meant by judicial immunity and why is it necessary to protect judges for judging? Secondly, how did the jurisprudence of judicial immunity evolve in Pakistan? Presenting a thorough analysis of the decisions in recent cases, this article argues that although the juridical position on the question of judicial immunity has gone back and forth, the Supreme Court has finally laid down a judicial doctrine that extends judicial immunity to administrative, executive, consultative, and legislative decisions of judges of the High Court. It has also made clear that High Court is not allowed to issue a writ against administrative, executive or consultative acts of its own or another High Court for the purpose of ensuring harmony in the working of judiciary.

Malaria, a very fatal disease that is killing millions of people for over 30 years. It is being caused by the parasites termed Plasmodium. Each species
of this parasite has its own different characteristics but the major deaths due to malaria are being caused by Plasmodium falciparum and
plasmodium vivax. Nano emulsions are formed by the mixture of two immiscible liquids in which one phase is dispersed in another phase. Mostly
nano-emulsions consist of oil molecules or droplets dispersed in a watery phase of water droplets dispersed in an oily phase depending on their
method of preparation. Nano emulsions show the separation of two different layers within them that is mostly termed phase separation. Primaquine
when incorporated into oral nano-emulsion having a particle size in the range of 50–200 nm showed effective antimalarial activity. Nano emulsion
of primaquine exhibited improved oral bioavailability. Nanoparticle were evaluated for dye test, Filter paper test, microscopy, refractive index, invitro release pattern.
INSIGHTS OF SHALE GAS EXPLORATION AND DEVELOPMENT IN INDIA: REVIEW
Authors: Kumar Susheel
Published: June 2021

Encouraging results of shale gas production in different countries viz. USA, China and Australia, India is also inspired to explore shale gas resources, which may not only support meeting the growing energy demand but also assist to reduce the import of hydrocarbons. This paper aims to review the current status of shale gas exploration programs in various sedimentary basins in India for a better understanding of the prospect of shale gas. The signicant thickness of organic-rich shale deposits is reported in various Gondwana and Tertiary sedimentary basins including Damodar valley, Krishna-Godavari, Cauvery, Cambay, Assam-Arakan, Ganga and Vindhayan basins. The geochemical properties like TOC and thermal maturity, Organo-inorganic mineral compositions, pore-network system, and depth of shale deposits are favoring the potential prospect of shale gas in India. Several agencies namely EIA, ONGC, USGS, Schlumberger, and CMPDI reported enormous resources of shale gas in its various sedimentary basins.
A PROSPECTIVE STUDY OF HD LAPAROSCOPIC VARICOCELE LIGATION FOR CHRONIC SCROTAL PAIN
Authors: Kaushal Devashish , Kumar Sandeep , Makkar Arun
Published: June 2021

Introduction: The prevalence of varicocele is approximately 15% in the general population, and about 2 -10 % of them have chronic scrotal pain.
Microsurgical or Laparoscopic testicular vein ligations are preferred surgical options for the patient refractory to conservative therapy. Previous
studies have proved the superiority of microscopic surgeries in painful varicocele treatment but the newer HD endo-vision system has improved
laparoscopic vision quality signicantly and testicular veins are identied more precisely than ever before. So there is a need to relook the results of
laparoscopic varicocele ligation. We have done a prospective observational study to assess patients' perceived changes in scrotal pain scores preand-post HD laparoscopic varicocele ligation.
Materials and Methods: This prospective observational study was conducted at a tertiary care referral center. All patients with scrotal pain were
evaluated for varicocele between September 2017 and December 2018. Varicocele patients with normal semen count with chronic scrotal pain not
responding to conservative therapy were included in the study. The Laparoscopic varicocele ligation surgeries were done by HD endo-vision
system under general or spinal anesthesia. Preoperative and post-operative universal pain scores were compared by Student's pair t-test.
Result: A total of 34 patients (mean age, 26.2±3.9 years) underwent Laparoscopic varicocele ligation for scrotal pain symptoms. Thirty-two
patients (94.11%) reported complete or marked resolution of pain at 3 months follow-up. There was no early or late postoperative complication
reported in any study patient. There was a marked improvement in the mean universal pain score, from 5.6 preoperatively to 1.1 postoperatively
(p=0.00011).
Conclusion: HD Laparoscopic varicocele ligation has a very high success rate with minimal post-operative complications in painful varicocele
management.
