PCR Using Q5® Hot Start High-Fidelity DNA Polymerase (M0493) v2
Authors: England Biolabs New
Published: February 2022

Q5®Hot Start High-Fidelity DNA Polymerase is a high-fidelity, thermostable, hot start DNA polymerase with 3´→ 5´ exonuclease activity, fused to a processivity-enhancing Sso7d domain to support robust DNA amplification. The addition of an aptamer-based inhibitor allows room temperature reaction setup. With an error rate ~280-fold lower than that ofTaqDNA Polymerase, Q5 Hot Start High-Fidelity DNA Polymerase is ideal for cloning and can be used for long or difficult amplicons. Q5 Hot Start High-Fidelity DNA Polymerase is supplied with an optimized buffer system that allows robust amplification regardless of GC content. The 5X Q5 Reaction Buffer contains 2 mM Mg++at final (1X) reaction concentrations and is recommended for most routine applications. For GC-rich targets (≥ 65% GC), amplification can be improved by the addition of the 5X Q5 High GC Enhancer. Q5 Hot Start High-Fidelity DNA Polymerase is unlike typical, lower fidelity PCR enzymes. To determine the optimal annealing temperatures for a given set of primers, use of the NEB TmCalculatoris highly recommended.
Anchoring Policies, Alignment Tensions: Reconciling New Zealand’s Climate Change Act and Emissions Trading Scheme
Authors: Inderberg Tor Håkon Jackson , Bailey Ian
Published: February 2022

Climate Change Acts (CCAs) seek to anchor national climate policy by establishing long-term targets and lines of accountability that guide the development of other climate policy instruments. However, counter-pressures to modify CCAs can occur where tensions exist with the provisions of already-established policies that enjoy substantial political and stakeholder support. Such tensions can be especially pronounced where CCAs necessitate major changes to emissions trading schemes (ETSs) that have formed the mainstay of efforts to reduce national emissions. This article employs a novel anchoring policy framework to examine the dynamics of aligning ETSs with CCAs. We investigate debates on reforms to the New Zealand Emissions Trading Scheme following the introduction of the Zero Carbon Act in 2019 to examine how alignment pressures between anchoring and subordinate policies are negotiated. The analysis reveals several tactics used to increase the acceptability of reforms to the New Zealand Emissions Trading Scheme and protect the Zero Carbon Act’s integrity. The article concludes by arguing that a greater understanding of alignment pressures between anchoring and subordinate policies is essential in enabling both CCAs and ETSs to contribute to achieving decarbonisation goals.
Self-Management of Housing and Urban Commons: New Belgrade and Reflections on Commons Today
Authors: Dragutinovic Anica , Pottgiesser Uta , Quist Wido
Published: February 2022

The concepts of collective management of housing and urban spaces are being revisited within the contemporary discussions about community-driven approaches and practices and, in particular, related to the revitalization of residential neighbourhoods. This research identifies the concepts of self-management and social ownership of housing in the post-World War II period in Yugoslavia as an important legacy of Yugoslav urban planning and housing policies. Although they were subsequently neglected, these concepts can contribute to contemporary global discussions about housing affordability and the role of community in ensuring spatial and social equality. New Belgrade mass housing blocks—the main site for testing the new dwelling concepts, in terms of both policies and modernist design—are the object of this research. The article is mainly a theoretical analysis of the issues of common interest and engagement, common good, and common spaces which played a decisive role in its design. The study applies interpretative and correlational research methods in re-theorizing these concepts and their underlying narratives. It traces how the perspectives on the collective practices and spaces evolved over time, revealing a correlation between changed social practices and the spatial deterioration of the New Belgrade mass housing blocks. The study highlights the importance of both collective practices and common spaces for addressing housing issues, emphasizing their instrumentality, and potentiality for rearticulating the dialogue between public and private, engaging citizens in interactive and inclusive decision-making and co-creation of the urban reality.

VOLUNTEER ORGANIZATIONS WORK AS A DETERMINING MARKER OF CIVIL SOCIETY DEVELOPMENT IN UKRAINE
Authors:   V. I. Vernadskyi National Library of Ukraine, Matviichuk Andrii
Published: February 2022

It analyses essential indicators of volunteering, volunteer work and the features of work conducted by volunteer organizations as an index of civic society development in Ukraine. The features of volunteer movements in Ukraine have been analyzed. It has been recognized that Ukrainian volunteer movement in 2014 become an unprecedented manifestation of public self-organization in its scale. The increasing of volunteer movement had been due to two chief factors: internal political crisis, that has led to the disbalance of the public administration systems, lack of quality management decisions, lack of resources, and external aggression which deepened the disbalance between the state’s ability to perform its functions effectively and ensuring the basic needs of the citizens. The crisis in the country and external influences had endangered the existence of Ukraine as a state, which has been received by its citizens as a personal challenge, as danger to their self-identification. It has been demonstrated that volunteer organizations are an influential social institute that acts on a voluntary basis and brings the country income and also solves a number of socially important issues instead of the state administration. In conclusion, volunteering is steadily becoming a foundation for civil society development. Without the work conducted by the volunteers it is hard to imagine NGOs and charities at all, the quality control over government and business becomes virtually impossible. Without volunteers there is not enough energy to fuel societal development, there’s not enough effort and time to help people in need, not enough creative potential for solving social problems.

Published: February 2022

Este trabajo analiza la evolución vertical de facies y el contenido en Ag y Bi de un testigo continuo extraído en el estuario medio del río Tinto (S.O. España). El análisis sedimentológico y paleontológico permite definir cuatro facies sedimentarias, características de depósitos aluviales (F1: 6,5-6,2 ka BP), la presencia de facies estuarinas durante la inundación marina del sector coincidente con el máximo transgresivo holoceno y el periodo inmediatamente posterior (F2: 6,2-5,2 ka BP), el tránsito a marismas (F3: 5,2 ka BP-siglo XIX) y un relleno antrópico de finales del siglo XX. Los contenidos de Ag y Bi permiten precisar tres periodos principales de contaminación histórica: i) inicio de las actividades mineras y explotación de Ag durante la edad de Bronce (~4,5-3,2 ka BP); ii) periodo de máxima intensidad de la explotación minera romana (siglos I-II DC); y iii) minería intensiva reciente (desde 1870).
Estudio del Frente montañoso de la zona de Falla Pinar, Cuba occidental, y su relación con la tectónica reciente
Authors: Estévez Cruz Elmidio , Cueto Gil Carlos Javier , Díaz Guanche Carlos , Ramírez Hernández Robert , Ordaz Hernández Alexis
Published: February 2022

La zona de falla Pinar es una gran dislocación tectónica de compleja historia cinemática, que se localiza en Cuba occidental, al sur de la Cordillera de Guaniguanico. Su estudio reviste gran importancia dado su naturaleza sismogénica. En la investigación se aplican herramientas de la geomorfología tectónica para evaluar las deformaciones activas asociadas a esta estructura. El procesamiento del modelo digital de elevación con 25 m de resolución espacial permitió extraer la red de drenaje sintética y sus subcuencas hidrográficas, delimitar el frente montañoso y cuantificar los parámetros geométricos de sus facetas triangulares. Los modelos empíricos de Tsimi y Ganas (2015) y De Polo y Anderson (2000) se utilizaron para estimar las tasas de levantamiento vertical a lo largo del frente montañoso, a partir de las pendientes y alturas de las facetas.  Como la actividad de la falla se refleja en las cuencas hidrográficas con las cuales está en contacto, las mismas fueron estudiadas empleando índices geomórficos como factor de asimetría (AF), integral hipsométrica (HI), relieve interno (DV), y densidad de puntos de ruptura del gradiente, entre otros. El estudio demostró que el frente en la parte oriental se caracteriza por presentar facetas bien definidas y de mayor altura y pendiente. Las variaciones de los índices geomórficos del frente y de las subcuencas hidrográficas a lo largo del rumbo de la falla reflejan cambios en su actividad tectónica reciente, y permitieron dividirla en tres segmentos geomórficos que se corresponden con bloques morfoestructurales. Finalmente, se pudo establecer que la tasa de levantamiento vertical fluctúa entre 0,04-0,71 mm/año, alcanzando los máximos valores en el segmento NE de la falla, donde manifiesta su mayor potencial sismogénico.

Se lleva a cabo el estudio geoarqueológico del Perfil A de la sala del Lago de la cueva del Ocho (complejo kárstico de las cuevas de Santiago, Cazalla de la Sierra, Sevilla, SO de España), con el objetivo de caracterizar la secuencia de ocupación antrópica de este sector de la cavidad, a partir del análisis de un depósito mediante técnicas de análisis arqueológicas, edafo-sedimentarias y geocronológicas. Los resultados obtenidos han permitido identificar una serie de unidades geoarqueológicas a partir de las cuales se ha establecido la secuencia de la ocupación antrópica de este sector de la cavidad. Se trata de una ocupación Neolítico antiguo, corta pero intensa, de cronología ca. 5300 cal. BC, que se conforma en el plazo de apenas 500 años y que queda sellada y amortizada en torno al cambio de era por una colada estalagmítica. Diferentes usos antrópicos caracterizan la conformación del depósito, desde una actividad ocupacional (hábitat) y redil inicial, que se transforma posteriormente en un ámbito de vertedero, reconociéndose depósitos con características sedimentológicas similares a los de tipo fumier, aunque desplazados de su lugar original. Los altos niveles de materia orgánica presente en los sedimentos, así como, de otras variables asociadas a la presencia humana (fósforo y susceptibilidad magnética) refuerzan la idea de la génesis antrópica del depósito. En este sentido, el estudio de la cerámica muestra que no se ha registrado ningún cambio tipológico ni tecnológico a lo largo de toda secuencia, siendo su tipo y características compatibles con las cronologías radiocarbónicas aportadas en el presente trabajo. A su vez, el estudio de arqueofauna muestra unos resultados, en cuanto a la presencia y manejo de fauna doméstica, propios de yacimientos correspondientes a las cronologías y el uso ofrecidos por la cueva del Ocho.

Indoor positioning prediction system based on wireless networks and depth sensing cameras
Authors: Duque Domingo Jaime , Cerrada Carlos , Valero Enrique
Published: February 2022

This work presents a new system for predicting the movement of people in indoor user environments, based on an advanced Indoor Positioning System (IPS) developed previously by the authors. The mentioned IPS proposes the combination of WiFi Positioning System (WPS) and depth maps provided by RGB-D cameras to improve the efficiency of existing methods, based uniquely on wire- less positioning techniques. In this approach, the prediction of movements is carried out by means of a proactive strategy, delivering the next estimated position of the person. This estimation provides a richer location and context information, which is useful for ubiquitous computing purposes. For example, energy consumption can be optimized if lighting or electronic devices are turned on/off by means of the user trajectory prediction. This paper shows how several techniques, applied for the developed IPS, offer different solutions to the indoor prediction problem, and it discusses about which of them gives better results.

It was established for the first time that not only the resonance of destruction is presented in nature, but also the resonance of creation. In modern medicine, resonance and destruction resonance are widely represented. But only the first steps are being taken in describing and using the concept of “resonance of creation” for diagnostics and therapy (8-13). There is no description and physical interpretation of this concept. This review is an attempt to discuss the phenomenon of "resonance of creation" and the results of its use in the treatment of various diseases.

The use of plant materials as the source of oil and functional foods is becoming more important with the new trends and scientific research. In this study, fig (Ficus carica) seed, which is a rarely found, seed and its oil, have been studied to determine the phytochemical properties for possible applications. Fig seeds were obtained from Aydın, Turkey. The oil was extracted by the cold press method. The seeds were analyzed for oil yield, protein, ash, ash insoluble in hydrochloric acid and trace elements. The oil was evaluated for fatty acid, sterol compositions by GC and the volatiles were analyzed with GCMS, tocopherols analyzed by HPLC, total phenolic content and antioxidant activity were determined spectrophotometrically. The oil was also evaluated for free fatty acid (FFA), refractive index (RI), peroxide (PV) and p-anisidine value. The results showed that F. carica has 22.7% oil yield and was characterized by linolenic (41.27%), linoleic (30.06%), and oleic acids (18.10%). Total phenolics were 79.5 mg GAE/100 g, and nine different sterol components were analyzed and β-sitosterol was at the highest rate. Theα-β-γ-δ tocopherol content was 6.088, 0.18, 634, 18 mgkg-1, respectively. Antioxidant capacity was 52.54%. Fenchone, cymene, styrene d-limonene, linalool, camphor were found as important volatiles. Quality parameters were FFA (% oleic acid) 0.90, RI (40 oC) 1.4721, PV (meq O2/kg oil) 2.2, p-anisidine 2.22. As a result, F. carica oil can be an alternative oil source and a good option for functional foods with their rich contentof phytochemicals. For the future, more studies need to be done for both the seeds and the oil for further applications. Keywords Ficus carica seed, cold-pressed oil, fig seed, phytochemical properties

Mucormycosis, also known as Zygomycosis or Black Fungus, is an infection caused in humans via various causative agents from the Zygomycetes class. Several countries including India is afflicted by the covid-19 virus, which has infected approximately 3.7 million people across the country. Some of the corona-positive patients suffer from another fatal infection, Mucormycosis, commonly known as Black Fungus. The strategy should be to administer an effective antifungal drug as soon as possible at the optimum dose. However, India being an epicenter of Diabetes with enormous 80 million diabetics, is of particular importance in the present scenario of the COVID pandemic. COVID therapy with Steroids and immune suppressants has increased the chances of infection in various individuals within the country with weaker immune system responses. The main purpose of this paper is to enlighten the community about the involvement of mucormycosis in covid-19 affected population and basic insights of its invasion.

Combination therapy or polytherapy is that uses more than one medication to treat a single disease and associated diseases. Pharmaceutical combination therapy may be achieved by prescribing separate drugs, or, where available, dosage forms that contain more than one active ingredient. A randomized efficacy phase 4 study is going on for prednisone in the treatment of multiple sclerosis, which is a neurodegenerative disease associated with many other disorders. A novel and accurate liquid chromatography tandem mass spectrometry method using electrospray ionization mode has been developed and validated for the simultaneous determination of prednisone (PDN), pioglitazone (PGZ) and teriflunomide (TFM) using imipramine (IMP) and ibuprofen (IBP) as internal standards (IS). The separation was carried on XTerra MS C18 (100 mm x 3.9 mm, 5 µm) reversed phase column using acetonitrile and 0.01M ammonium formate as the mobile phase in gradient mode at 1.0 mL/min. The method was validated in terms of specificity, linearity, accuracy and precision over the concentration range of 1–500 ng/mL. The intra and inter-day precision and accuracy, stability and extraction recoveries of all the analytes were found in the range of 97.2-102.2%. The lower limit of quantitation was 1.0 ng/mL for all the 3 analytes and the extraction recovery values were more than 65%. The method proved highly reproducible and sensitive and was successfully applied to pharmacokinetic study after single dose oral administration of PDN, PGZ and TFM to the rats.

Authors:   Faculty of Psychology and Education Sciences Brasov, „Spiru Haret” University,  Romania, ANDRONIC Răzvan-Lucian
Published: February 2022

The participation of personnel from the defense, public order and national security structures of the Romanian state in international missions to combat terrorism, support peace or humanitarian began in 1993 and continues today (being involved so far over 55,000 soldiers, according to official sources). Only this year, the Ministry of National Defense (MApN) will participate with a staff of 1940 military and civilians in missions and operations outside the Romanian state, and the Ministry of Internal Affairs (MIA) will contribute 841 soldiers and police. In all these years, at least 1500 people / year were involved, who performed missions in at least 3 different locations around the world. Deployment in a theater of operations is equivalent to carrying out complex missions, with a high degree of risk and exposure to extreme dangers, which left wounds seen and unseen. A number of 30 soldiers fell on duty, and another 177 soldiers were seriously injured in the theaters of operations, most of them being classified as disabled. Unseen wounds acquired as a result of exposure to potentially traumatic events take the form of post-traumatic stress disorder and comorbid conditions (PTSD, which affects between 5% and 18% of those participating in such missions in partner countries).
THE ADAPTATION OF THE AIR FORCE DOCTRINE TO THE ROMANIA NATIONAL DEFENSE STRATEGY
Authors:   „Henri Coandă” Air Force Academy, Braşov, Romania, CHIOSEAUA Bogdan-Cezar
Published: February 2022

From military theorists` perspective, the airspace is an area from which objectives of strategic importance to the enemy can be effectively engaged and neutralized, in order to disorganize the command and control system at strategic level, as well as to diminish the enemy’s operational potential to develop and the tactical effort in the area / areas where military actions are carried out. From this point of view, maintaining control of the airspace is a necessary condition for providing national security, and this can be achieved by constantly updating the doctrine of the air force, the one that manages the use of airborne vectors (aviation, missiles, artillery, drones, etc.) and supports the development of specific infrastructures, research and production elements, as well as modern structures for the educational and training needs of the Air Force. The airspace and going beyond that, the circumterestrial space are areas where there are no physical limitations or obstacles, geographical or relief conditions as found in districts where land forces operate or in the areas of military operations carried out by naval forces. Given the lack of these restrictions, the branch that uses the airspace has a unique feature, namely ubiquity, a characteristic that outlines the special importance of air force and air doctrine in meeting the objectives of military strategy and national security.

Published: February 2022

Mencit dikenal sebagai salah satu jenis hewan coba yang mudah dikembangbiakan. Beberapa galur mencit telah digunakan secara luas untuk tujuan riset eksperimental maupun komparatif. Akan tetapi, kontrol genetik dan beberapa aspek pemeliharaan lainnya seringkali kurang diperhatikan terutama pada peternakan mencit tradisional. Hal ini dapat memicu kemunculan beberapa jenis penyakit yang menyebabkan kerugian ekonomi peternak. Salah satu penyakit akibat rendahnya kualitas manajemen pemeliharaan mencit adalah kemunculan massa abnormal superfisial. Studi ini bertujuan untuk mengeksplorasi variasi dan karakter morfologis dari temuan massa abnormal superfisial dari mencit-mencit di Malang Raya. Sebanyak 54 ekor mencit dengan massa abnormal superfisial dikoleksi dari tujuh peternakan mencit dan dieutanasi berdasar aturan berlaku. Pemeriksaan makroskopik dan mikroskopik dilakukan dengan prosedur standar. Pemeriksaan sitologi dilakukan dengan prosedur Fine Needle Aspiration dengan pewarnaan Giemsa. Dua jenis morfologi utama yang dapat dikenali dikategorikan sebagai massa non-neoplastik dan nonneoplastik. Pemeriksaan sitologi pada massa neoplastik menunjukkan selularitas yang tinggi didominasi sel-sel epitelial sedangkan pada massa nonneoplastik didominasi oleh leukosit dan eritrosit. Arsitektur histopatologi dari 36 massa neoplastik menunjukkan karakter adenokarsinoma mammae sedangkan pada massa noneoplastik lebih bervariasi antara lain abses subkutan (13), hematoma (1), krusta (2), dan nodul granulasi (2). Simpulannya adalah massa abnormal superfisial yang muncul pada mencit-mencit yang dibudidayakan di Malang Raya dapat berupa adenokarsinoma, abses subkutan, dan hematoma. Kejadian adenokarsinoma mendominasi jenis massa yang ditemukan disusul oleh abses subkutan dan hematoma.

Published: February 2022

The memoirs of (post-) punk musician Viv Albertine address the issue of choice or lack thereof in romantic and family relationships. They depict a world in which choice of romantic partners appears normal if often unsuccessful, whereas choice within family relationships is restricted. It is self-evident that one cannot choose one’s blood relatives. However, amplified by Albertine’s scepticism towards any social relationships, her two memoirs represent ‘negative choice’ (Eva Illouz) in heterosexual romantic relationships and the complex ways in which negative choice can change family dynamics. In her memoirs, Albertine presents loneliness as the opposite of love which aligns with her model of choice, as it is preferable to live a lonely life over being bound up in love relationships, romantic or familial, which are harmful to one’s wellbeing. This article demonstrates how the ethos of early punk is translated into an uncompromising process of life writing which presents itself as faithfulness towards the individual’s core need for self-realisation and self-expression against the backdrop of failing romantic and familial relationships, severe physical and mental health problems, a self-diagnosis of autism and a patriarchal society.

Abstract

This study aims to determine the level of student optimism and the need to develop Web-based Acceptance and Commitment Therapy (ACT) as a strategy to increase student optimism. Convenience sampling was used to collect data on 283 students. The instruments used are the Life Orientation Test-Revised (LOT-R) and the ACT Web-based media needs questionnaire. The results showed that the level of student optimism in Jakarta was moderate (16.6 out of a total score of 24). Overall 44 students (16%) had a low level of optimism, 159 students (56%) had a moderate level of optimism, 80 students (28%) had a high level of optimism. Women had higher levels of optimism than men (16.7 vs 16.3). 158 students (63%) felt the need for a self-help web to increase optimism so that students could increase their optimism. It is also known that the development of Web-based ACT is also very important to help increase student optimism.

The development of learning by involving technology is one of the impacts of the rapid development of technology. Currently educators are still determining the appropriate learning model for the teaching process, the lack of teaching time in schools is one of the problems that arise and understanding student concepts is also the reason student learning outcomes are not satisfactory. There are many challenges faced by teachers and students in learning mathematics today. Several alternative solutions to these challenges can be found in the literature, one of which is by implementing a flipped classroom. In the flipped classroom, learning activities that are usually carried out in the classroom are carried out outside the classroom. Thus, activities in the classroom can be focused on activities that can stimulate students to think at a higher level. Although it looks promising, this kind of learning does not always have a positive impact on student learning. Therefore, this flipped classroom needs to be designed in such a way that it has more value in terms of learning design. Providing flipped classroom learning design elements into this learning will have the potential to increase the quality of mathematics learning. Therefore, this article will review the literature related to the flipped classroom learning design in learning mathematics on vector material. Specifically, this article will examine the definition and design of the flipped classroom, along with the challenges of its implementation. Finally, this article will review studies that have designed and implemented flipped classrooms in mathematics learning, especially in vector material. From the results of the theoretical study, it can be concluded that the steps in the design of vector material flipped classrooms can support mathematics learning and have the opportunity to be developed in various units of education level.
