Authors: Keithley L. Amory  , John M. Gill
Published: October 2020

Los explantes de hojas jóvenes de Liriope muscari ofrecen una fuente de gran disponibilidad para propagación in vitro en países de climas cálidos donde la florecida es escasa. Se obtuvo callo de hojas tiernas colocadas en medio sólido de sales y vitaminas de Murashige and Skoog (MS), 3% sucrosa, 0.7% agar, y los reguladores de crecimiento ácido 2,4-diclorofenoxiácetico (2, 4-D) a 1 mg/L y 6-furfurilaminopunna (kinetina) a 1 mg/L. Se obtuvo callo sólo del área proximal de las hojas. Este callo produjo plántulas al ser colocado en medio de MS, 3% sucrosa, 0.7% agar y la citoquinina N6 (2-isopentenil) adenina (2 ip) a 10 mg/L. El uso de secciones de hojas como fuente de explante para la propagación en masa de Liriope es posible. Sin embargo, en variedades variegadas, sólo se obtuvieron plantas de colores verdes o blancas debido posiblemente a una quimera en el tejido original.
Concentración de inóculo adecuada para estudiar la relación entre plántulas de cafeto y Rhizoctonia solani o Myrothecium roridum
Authors: Wanda I. Mercado  , Rocío del P. Rodríguez
Published: October 2020

Se determinó el nivel adecuado de inoculo de Rhizoctonia solani y Myrothecium roridum para la inducción de síntomas en plántulas de cafeto (Coffea arabica L.) basado en el porcentaje de mortandad y la incidencia de la enfermedad. Se encontró que para R. solani y M. roridum el nivel de inoculo adecuado fue 15 y 10%, respectivamente. Myrothecium roridum fue más virulento que R. solani ocasionando mayor mortandad en las plántulas de cafeto. Para ambos patógenos, a medida que aumenta la concentración del inoculo disminuye el peso seco de las plántulas. Hay relación directa positiva entre la incidencia de la enfermedad y la concentración del inoculo, donde a medida que aumenta la concentración aumenta la incidencia de la enfermedad. Se encontró que R. solani es más persistente que M. roridum en el suelo inoculado.

Published: October 2020

Se realizó una investigación para evaluar el efecto de niveles de abonamiento con nitrógeno, fósforo y potasio en la producción, calidad y concentración foliar de nutrimentos del tangelo 'Orlando' en un suelo Corozal arcilloso. Los niveles de nitrógeno evaluados fueron 0,85.2,170 y 341 kg/ha; los de fósforo fueron 0,12.4,24.8 y 49.6 kg/ha y los de potasio fueron 0,47.8, 94.6 y 188 kg/ha. Se obtuvo una respuesta lineal entre los niveles de nitrógeno y la producción acumulativa de frutas de tangelo 'Orlando'. Según aumentaron las aplicaciones de nitrógeno aumentó la producción de frutas. Los niveles de fósforo y potasio no afectaron la producción de frutas. Los distintos niveles de nitrógeno, fósforo y potasio no afectaron significativamente el peso promedio de la fruta y su calidad en términos de pH, brix, acidez y relación brix/acidez. Las aplicaciones de nitrógeno afectaron significativamente las concentraciones foliares de nitrógeno, calcio, potasio y fósforo. Las aplicaciones de fósforo afectaron las concentraciones foliares de calcio y potasio. Las aplicaciones de potasio no afectaron significativamente las concentraciones foliares de ninguno de los elementos.
Live weight and body condition changes in dry cows at pasture and effects on subsequent performance.
Authors: Randel Paul F.
Published: October 2020

During a 720-d experiment in a Holstein and Brown Swiss herd, two feeding regimens were compared during the grazing phase of dry cow management until confinement before expected calving.The two treatments involved rotational grazing (24-d cycles) at a stocking rate of 2.5 animals per hectare in; (A) all-grass swards or (B) all-grass plus 3 h daily access to swards of Leucaena leucocephala and grasses, Large heifers were added as needed to maintain constant group size at pasture. A daily supplement of 2 kg/head of bulky concentrate was fed. During the first 19 mo of the study, while rainfall was adequate, dry cows in treatments A and B gained live weight (LW) satisfactorily (0.69 ± 0.26 and 0.67 ± 0.23 kg/d) and increased in body condition score (BCS) on a scale of 1 to 5 at rates of 0.40 and 0.34 point/100 d, respectively. During the final 5 mo, pasture conditions and LW gains were poor because of prolonged drought. Monthly rainfall of 50 mm or more maintained grazing conditions adequate for use with the present level of supplemental feeding. There were no differences (P > 0.05) between treatments. Under common postpartum management, standard 305-d lactational milk yields were unaffected by previous treatments A or B. However, a positive trend (P < 0.10) was associated with higher prepartum BCS. Cows that scored 3.5 produced 4,013; 4,111; 4,367; 4,627 and 4,450 kg, respectively. Postcalving reproductive performance was not affected by previous treatment or by BCS prepartum or BCS at 6 wk postpartum.

Authors: James R. Smith
Published: October 2020

Heterodera glycines, un patógeno destructivo de la soya (Glycine max L. Werr.), se descubrió recientemente en Puerto Rico. La habichuela común (Phaseolus vulgaris L.) también sirve como hospedero, pero todavía no se na determinado el efecto de H. glycines en el rendimiento de este cultivo. El objetivo de este estudio fue determinar el efecto de Â¡a población raza 2 de H. glycines, que se descubrió en Puerto Rico, en el rendimiento de la habichuela común. Tres líneas resistentes y tres líneas sin resistencia se infestaron con tres niveles (0, 4,000, y 8,000 huevos y jóvenes por tiesto) de H. glycines raza 2. Se utilizó un arreglo factorial de líneas y niveles de infestación en un diseño de bloques completos afeatorizados con seis replicaciones. El estudio se realizó en un invernadero en Isabela, Puerto Rico, en 2000. Se recolectaron datos para el número de semillas, número de vainas, y el peso de semillas por planta. No se observó efecto de H. glycines sobre los componentes de rendimiento. Hubo diferencias entre las líneas para loscomponentes de rendimiento, pero estas diferencias se asociaron con factores genotípicos no relacionados con H. glycines. Se concluyó, tentativamente, que H. glycines no afectará el rendimiento de habichuela común en Puerto Rico. Sin embargo, se recomendaron estudios adicionales con H. glycines y habichuela común usando suelos de textura más gruesa.

Published: October 2020

Durante 2002 y 2003 se realizaron dos experimentos de campo en la Estación Experimental Agrícola de Lajas para evaluar la fitotoxicidad y la eficacia en el control de malezas de los herbicidas oxyfluorfen [2-chloro-1-(3- ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene] y halosulfuron-methyl [methyl 5-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonylaminosulfonyl]-3- chloro-1-methyl-1-H-pyrazole-4-carboxylate] aplicados a tres diferentes tiempos y dosis después de la siembra de cebolla (Allium cepaL). En el primer experimento, las aplicaciones tempranas de oxyfluorfen a 0.13 y 0.27 kg ia/ha a los 5,10 y 15 días después de la emergencia (DDE) de la cebolla causaron menor fitotoxicidad (≤30%) que aplicaciones simultáneas de halosulfuron-methyl a 0.027 y 0.054 kg ia/ha, las cuales fueron 100% fitotóxicas. Diez días después de la aplicación (DDA) del herbicida, la menor densidad de malezas (siete plantas por 0.5 m2) se obtuvo con el tratamiento de oxyfluorfen aplicado a los 15 DDE; sin embargo, 20 DDA la densidad de malezas fue menor con la aplicación del mismo herbicida a los 5 DDE (cinco plantas por 0.5 m2). Con ambas dosis de halosulfuron-methyl se obtuvieron densidades de malezas más altas densidades de malezas más altas (≥52 plantas por 0.5 m2), irrespectivo del tiempo de aplicación. En el segundo experimento, la aplicación de halosulfuron- methyl a los 35 DDE a parcelas previamente tratadas con oxyfluorfen a los 5, 10 y 15 DDE causó daño severo (≥80%) a la cebolla. Con relación al control de malezas, la mejor combinación de ambos herbicidas fue la aplicación de oxyfluorfen a los 10 DDE seguido de halosulfuron-methyl a los 35 DDE; sin embargo, este tratamiento no fue mejor que la aplicación de oxyfluorfen solo a los 10 DDE. Con oxyfluorfen solo a los 10 DDE se obtuvo mayor rendimiento y número de cebollas que con los demás tratamientos de herbicidas. La aplicación de halosulfuron-methyl a los 35 DDE redujo el rendimiento de la cebolla en más de 97%, por lo que no se debe usar este herbicida en este cultivo.

Published: October 2020

El clon 2-4 de chironja (Citrus sinensis x Citrus paradisiaca) fue evaluado durante los primeros ocho años de crecimiento en las localidades de Isabela y Corozal, Puerto Rico. Los árboles se injertaron en los patrones 'Swingle citrumelo' (Citrus paradisi x Poncirus trifoliata), 'Naronja' (Citrus paradisi x Citrus aurantium), en las mandarinas 'Cleopatra' y 'Sun Chu Sha' (Citrus reticulata), y en el híbrido HRS 812 (Sunki x Beneck trifoliate orange). En ambas localidades, los árboles en la combinación Swingle-chironja murieron durante el primer año de injertados, posiblemente por incompatibilidad de injerto patrón. El patrón HRS 812 resultó ser uno de los mejores productores, aún cuando estuvo infectado con la cepa severa del virus de la tristeza de los cítricos (VTC) en ambas localidades. Aunque las frutas en este patrón fueron de tamaño pequeño, la cantidad de jugo que produjo fue significativamente superior a la de los demás patrones. Los árboles de Chironja injertados sobre Naronja fueron afectados por el VTC; un 38% murieron en Isabela y 25% en Corozal. Sin embargo, los árboles en este patrón crecieron vigorosos y resultaron buenos productores con frutas de buen tamaño y calidad moderada. La alta incidencia de VTC y Phytophthora spp. fue un factor limitante para los patrones susceptibles a estas enfermedades, por lo que hubo una alta mortandad de los árboles.

Dry matter yield and chemical content of forage sorghums intercropping with annual legumes.
Authors: Colbert Raphael W. , Valencia Elide , Beaver James S.
Published: October 2020

Forage sorghum [Sorghum bicolor L. Moench 'Brown midrib' (BMR)] and annual legumes lablab [Lablab purpureus L. 'Rongai' (L)] and mucuna [Mucuna pruriens L. 'Vine 90 d' (M)] are suitable fodder for the dairy industry in Puerto Rico, but BMR harvested at 90 days, usually has low crude protein (CP, 6%) content, which limits its usefulness. There is the possibility of increasing the CP by intercropping legumes with BMR, but this option has been only slightly investigated. This study proposes to compare BMR in monoculture and in intercropping with 'Rongai' (SL) and 'Vine 90 d' (SM), in addition to L and M in monoculture, in terms of total leaf mass (FM) and botanical components (sorghum, legumes and weeds) and chemical (CP and fiber fractions) at two harvest times. The experimental plots (25 m2) were sown in February and August 2008 in a randomized complete block design with five replications. At each harvest time, 2 m2 MF area was sampled 90 days after sowing. Data were analyzed by using the MIXED procedure of SAS and mean separation tests were performed by using F-protected LSD at 95% level of confidence. No significant differences (combining fodder botanical component and weeds) were detected for the total MF between BMR and BMR associated with legumes in monoculture, with mean values of 8.94, 8.81, and 8.42 Mg/ha for BMR-'Rongai', BMR-'Vine 90 d', and BMR, respectively. Overall, there was no significant difference in MF between May and August (8.1 vs. 7.5 Mg/ha). 'Rongai' yield (Mg/ha) did not change between May and August (3.6 vs. 3.0) but was lower in the intercrop (2.74) than in monoculture (3.94). 'Vine 90 d' had the lowest yield of 2.8 and 1.3 Mg/ ha in May and August, respectively. No differences (P > 0.05) in NDF and ADF content between BMR and BMR-'Rongai'-'Vine 90 d', whose values were 60.1 and 63.9% and 40.1 and 46.5%, respectively. However, differences (P < 0.05) were found in CP content between monoculture and intercropping, with values of 14.1, 11.1, and 6.0% for 'Rongai', 'Vine 90 d', and sole BMR, respectively, whereas the BMR-'Rongai' and BMR- 'Vine 90 d' CP were 9.8 and 9.1%, but these last values exceed by three units the percentage in BMR. In conclusion, BMR intercropped with 'Rongai' and 'Vine 90 d' improved the forage chemistry and helps to control weeds while favoring the performance of desirable botanical components.

Functioning of food enterprises in the context of export development policies implementation
Authors: Galeev Marat Mirsayafovich , Baleevskikh Alexander Sergeevich
Published: October 2020

The article describes the development trends of the modern poultry product subcomplex as a raw material base for food industry and state export activity. Import substitution and increasing export volumes are a priority for the federal and regional development policies of Russia. In this regard, the aim of the study was to analyze the current state of food industry in the context of policy implementation of import substitution and export development. The achievement of the set goal was disclosed by solving several interrelated tasks: 1) analysis of resources of food products (eggs and egg products) and their use; 2) identification of a hidden correlation between indicators “production” and “import”; 3) identification of a hidden correlation between indicators “production” and “export”. We hypothesized that indicators “production” and “export” of agri-food are directly correlated. Studies to identify hidden correlation dependencies have shown that there is a direct correlation between indicators “production” and “import”. Indicators “production” and “export” don’t have dependencies and influence on each other, therefore an increase in production doesn’t affect the direct export of eggs from the country.
Remote work: development of employee digital competence
Authors: Tsareva Natalia A. , Omelyanenko Sofiya Yu.
Published: October 2020

Remote work in the context of global computerization of all work processes is an integral part of the functioning of companies. With the growing number of employees working remotely, it is important to conduct correctly the adaptation period for the transition to a new communication format for both employees and the candidates for a vacancy. The aim of this article is to survey a number of classifications of employee digital competencies proposed by scientists. The study was carried out on the use of tools by employees in a stressed work format: it was revealed that when employees possess the skills to use digital tools for remote work, company managers do not use these skills when building communications and working in new conditions. The analysis of the resume base is given in order to determine the formation of digital competence among the candidates. A toolkit has been developed to determine the formation of digital competence and assess the effectiveness of an employee at remote work.

The study was carried out in the sanitary landfill of Puno, from December 2017 to January 2018 and aimed to determine the relationship between working conditions and the risk factors faced by waste pickers from the Cancharani sanitary landfill, Puno-Peru. The methodology applied corresponds to the transversal correlational design, with a census-type study sample. The statistical tests applied were the Spearman correlation test and the Mann Whitney U test. The results indicate that there is no correlation (r = 0.102; α = 0.01), between working conditions and the risk factors that workers face. With regard to gender, it was found that women admit the inadequate working conditions in which they work (U = 60.00), considering that they are the same who manipulate solid waste from dangerous places such as pharmacies and others without optimal protection. On the other hand, men are the ones who perceive more the risk factors they face (U = 50.00) and are the ones who handle the waste coming from the homes. According to the age ranges, it was obtained that those aged 18 to 29 identify and perceive the inadequate working conditions in which they work (RP = 96.50). Likewise, it is those of this age range who identify the risk factors to which they are subject (PR = 91.00). We can conclude that the work situations and the risk factors are not significantly related.

Published: October 2020

Today, the boundaries of international crime involving states and transnational organized crime are slowly blurring, and as a result, the number of international crimes is steadily growing. The article analyzes two key groups of crimes: crimes indicated in the Rome Statute and transnational crimes under international conventions. This article is based on the analysis of the main groups of crimes: the first group of international crimes committed with state actors, which includes crimes against humanity, war crimes, crimes of aggression, crimes of genocide; and the second group, crimes committed by criminal groups organized in more than one country with the "international" or "transnational" character of such acts. The authors emphasize the norms of international law, according to which the International Criminal Court, together with international criminal tribunals, have jurisdiction over a small range of key international crimes, including genocide, war crimes and crimes against humanity, aggression, committed by state officials. The main objective of this research is to compare the mechanism for investigating crimes in the jurisdiction of international criminal tribunals and the International Criminal Court, together with the national procedure for investigating transnational crimes, through the ratification of international conventions and the establishment of the International cooperation. The article was made with the following methods: induction, deduction, analogy, as well as historical, dialectical and formal legal methods.

Published: October 2020

The growing volumes of information and rapidly changing requirements of the professional training of students in higher education institutions make it necessary for students to seek internal reserves to master professional skills. In modern conditions, the process of professional self-organization of students is being updated. This is reflected in the requirements of the new Russian federal state educational standards of higher education in the form of key general competencies. One of them is "the ability to manage your time, build and implement the path of self-development based on the principles of education throughout life." The purpose of the article is to review the experience of developing professional self-organization among students. Professional self-organization can be understood as the process of mobilizing the capacities of the individual to achieve goals. Professional self-organization is a constantly evolving process of internal rationalization of educational activities. The crucial thing in the learning process must belong to the control of the student, since the learning activity is characterized by the active position of the student. The article presents the experience of developing the self-organization competence based on the example of the study of the cycle of general humanistic disciplines. Both individual and group forms of work are used in the training of students, electronic means are involved. To develop independence, students, with the advisory support of a teacher, complete projects, cases, tests, final assignments and other tasks. The training of the competence under consideration allows the future specialist to successfully analyze the task, contributes to rational planning, proper evaluation, timely adjustment and improvement of the process of educational activity and its management.

Published: October 2020

The article is devoted to the problem of transformation of family values, the emergence of new types of families in the context of modern marriage. The authors believe that in post-Soviet society in Russia, the axiological approach is the most heuristic in the study of marriage. The authors used a psychological analysis of the life-meaning orientations of spouses with a traditional type of marriage and spouses focused on voluntary childlessness. The results of the study showed that the specifics of life and life orientations of the husband and wife, their personal characteristics determine the attitudes and expectations of marital relations, the choice of the type of family. It was revealed that the life orientations of spouses who support voluntary childlessness are contradictory: men, when they are dissatisfied with their lives in the present and not confident in their abilities, focused on getting pleasure as the meaning of life here and now; and the wife, experiencing the riches of his life, demonstrating the confidence, commitment to the future, a higher meaning of life. Spouses from the traditional type of family are both happy with their lives. At the same time, husbands are characterized by an average level of meaningfulness of life, focus on the implementation of current tasks, and wives with a high sense of life are focused on the future, are confident in the possibility of building a life in accordance with their ideas about its meaning and life goals.

Authors: Abrosimova Evgenia E.
Published: October 2020

The aim of the article is to address the socialization processes of modern children and adolescents, in the context of the characteristics of the information society and the constant presence of the Internet in their lives. A new but emerging phenomenon is emerging, video blogging, which is part of Internet socialization. The main characteristic of this phenomenon is the potential opportunity that children and adolescents have to create an independent video blogging process, which affects the socialization process in general. The empirical data were collected using quantitative and qualitative sociological methods: survey and interview with children. The combination of these methods provides more complete information to understand the problem. The main result of this study is the evidence that around 30% of children and adolescents are not only viewers of videoblogs, they not only consume the information disseminated by this part of the global network, but also become independent authors of videoblogs. The study results reflect the fact that many children's authors try to imitate their favorite video bloggers. Young Internet users perceive the process of creating a video blog as a certain type of creativity.
Erken Cumhuriyet Dönemi Türkiyesi’nde Asri Ev Tartışmaları ve Elektrikli Tenvirat

Türkiye’nin ulus-devletleşme sürecinde elektrik enerjisi ve teknolojisi kullanımı endüstriyel ve kamusal mekânların yanı sıra ev içinde de teşvik edilmiş ve rasyonelleşmiş bir ev içi

kültürü oluşturulmaya çalışılmıştı. Cumhuriyet’in elektrikle aydınlatılan yeni teşhir mekânları ise yeni bir gelecek vaadiyle bu mekânlarda bir araya gelen toplum bireyleri için hayranlık, iyimserlik, aidiyet ve birliktelik ruhunu yaratmayı hedeflemişti. Bu ruhun uzandığı asri ev de yeni rejimin teşhir mekânlarından birisi olarak kurgulanmıştı. Elektrikli aydınlatma kullanımının teşvik süreci, yeni rejimin arzuladığı rasyonel, bilimsel, verimli, ölçülü, sıhhatli, hijyenik vatandaş inşası süreciyle paralel ilerlemiş, hatta bu ürünler çağdaş kadın, erkek ve çocuk imgeleri eşliğinde sunularak, rejimin “asrilik” vurgusu böylelikle pekiştirilmek istenmiştir. Elektrik ışığı, bir yandan zamanın ruhunu evlerin içine taşırken diğer yandan yeni rutinler ve yeni nesnelerin birbiriyle kurduğu işlevsel bağı tamamlayıcı bir rol de üstlenmiştir. Böylelikle yönetici iktidarın hedeflerinin de ötesinde, elektrik teknolojisinin kendisi bir tarihsel aktör olarak ev içini dönüştürmüş, Cumhuriyet’in soyut modernizasyon söylemlerinin nesnelleştirilmesinde kilit bir rol oynamış ve kendi materyal kültürünü yaratmıştı. Cumhuriyet’in ilk yıllarında ev içi mekânda elektrikli tenvirat kullanımının “asrileşme” çabalarını nasıl şekillendirdiğini söylemsel ve pratik düzeyde inceleyen bu çalışma, domestik mekânda elektrikli tenvirat kullanımını teşvik eden resmi ve popüler yayınlardan faydalanarak, uluslararası düzeyde de ilgi konusu olan fenni ve asrî ev tartışmalarına interdisipliner bir yaklaşım getirmeye çalışmaktadır.

Authors: Zeiträg Julia , Baumjohann Dirk
Published: October 2020

Follikuläre T-Helferzellen (Tfh-Zellen) sind ein spezialisierter Subtyp innerhalb der CD4+-T-Helferzellen, deren Hauptaufgabe darin besteht, B-Zell-Hilfe zu leisten. Sie sind von essenzieller Bedeutung für die Generierung hochwirksamer Antikörper und sie fördern die Differenzierung von B-Zellen in Plasmazellen und Gedächtnis-B-Zellen. Somit sind Tfh-Zellen entscheidend am Schutz vor Infektionen und deren Bekämpfung beteiligt. Geraten Tfh-Zellen außer Kontrolle, kann dies jedoch Krankheiten wie Autoimmunität, Allergien oder Krebs verursachen. Als ein wichtiger Bestandteil der adaptiven Immunantwort bilden Tfh-Zellen einen vielversprechenden Ansatzpunkt für die Entwicklung hochwirksamer Impfstoffe und neuer Therapien zur Bekämpfung verschiedener Erkrankungen

Abstract

Objective: To evaluate the success, degree of difficulty and completion time of endotracheal intubation without removing the endotracheal tube in the event of an oesophageal intubation.

Methods: The prospective, randomised crossover study was conducted at Gulhane Training and Research Hospital, Ankara, Turkey, from July 1, 2018, to August 31, 2018, and used a manikin model. Endotracheal intubation was performed using Miller, Macintosh blades and a video laryngoscope. The procedures were randomised into two groups, with group E+ being subjected to it while an endotracheal tube ETT was placed in the oesophagus (E+) simulating the oesophageal intubation, and control group E- getting the standard procedure without the endotracheal tube in the oesophagus. All methods were evaluated for their success, completion time, and degree of difficulty. Data was analysed using SPSS 22.

Results: There were 120 manikins, with 60(50%) in each of the two groups.  The mean completion time with Miller in E+ group was 19.05±9.65 and for E- it was 17.55±11.95 seconds. With Macintosh, E+ had a mean completion time of 19.85±12.66 seconds and E- had 16.75±8.66. With video laryngoscope, E+ group  had a mean completion time of 16.75±8.66 seconds, while E- had it 14.60±8.17. No significant difference was found in the paired group comparisons in terms of the degree of task difficulty (p>0.05).

Conclusion: In case of inadvertent oesophageal intubation condition, leaving the tube in the oesophagus and performing subsequent endotracheal intubation attempts was not found to decrease the rate of success regardless of the laryngoscope type.

Deep brain stimulation for Parkinson’s disease in Pakistan: current status, opportunities and challenges
Authors: Nabeel Muzaffar Syed  , John Bertoni  , Danish Ejaz Bhatti
Published: October 2020

Abstract

Parkinson’s disease is a slowly progressive neurodegenerative disease that commonly affects people aged 60 years and above. So far, no treatment has been shown to halt or slow the progression of the disease and our options are limited to symptomatic management. Levodopa is the most preferred antiparkinsonian medication that provides excellent control of symptoms early in the disease. However, in most patients the response declines over time and complications of motor fluctuations and dyskinesia arise. Other medical therapies play an adjunctive role in the management, as they are not as effective as levodopa. Advanced therapies like deep brain stimulation (DBS) can provide effective control of symptoms in moderate to advanced disease. Deep brain stimulation surgery has recently been started in Pakistan. This review provides an overview of deep brain stimulation, its indications, patient selection process and details of surgery,

Published: October 2020

Objective: To analyse the clinical features of perineal endometriosis (PEM), its treatment and outcome.
Methods: Prospective, single-centre study with 13 patients with PEM who were treated between 2011-2018
at Domingo Luciani Hospital and mean followed up for 58.4 months. Results: Mean age was 32,2 years.
All cases had a history of vaginal delivery with an episiotomy. All complained of perineal pain related to
the menstrual cycle; the perineal mass progressively increased in size and was tender during menstrual
periods. Mean VAS was 7. 69,2% with rectal bleeding. The mean size of the lesion was 3.42 cm. CA125
levels were measured in all patients, 3 (23,1%) with abnormal range; all patients were subjected to
transvaginal, endoanal ultrasonography (EUS) and FNAB before surgery. Anal sphincter (AS) involvement
was demonstrated by EUS in 46.2% (6). Mean EUS pre-treatment volume 18.98 ml. First, these 6 patients
received hormonal therapy based on GnRH and evaluated response. Mean EUS post-treatment volume
10.21 ml p < 0.05. Complete local excision was performed on all cases. Mean CCFIS preoperative was 2.46
and postoperative 3.01 p=0.01. No major complications or recurrences were noted. Conclusion: PEM
presents with typical clinical features when it involves the AS, it could benefit from first a hormonal therapy
before surgery. EUS is a useful preoperative tool to decide what we should do. The main idea at the time of
surgery is performed a complete local excision with non-touch AS, and in cases where these aren’t possible,
a sphincteroplasty is mandatory with good continence results, minor complications and no recurrences.

Authors: Bhatt Narendra , Deshpande Manasi , Chaskar Sunetra
Published: October 2020

A Kwatha, decoction, is one of the most used classical Ayurvedic dosage forms. It is a liquid preparation to be freshly consumed. For this preparation the raw material, mostly herbs or a group of herbs are extracted in water by boiling them for a specific time span. This is second part of the review paper on Ayurvedic Kwatha - herbal decoction to review and consider various approaches and their outcomes for the standardization. It provides information and reference data for the standardization of decoction across conventional methods and new techniques and explains how this classical process has evolved within new pharmaceutical developments. Many Ayurvedic production units appear to have adapted to newer manufacturing technologies including fermentation techniques. This paper explores the scope for application of newer technologies for the purpose of better standardization and novel product applications. Application of Kwatha's nano-drug delivery systems have a promising potential to enhance operation and resolve issues related to classical dosage forms. In order to tackle further chronic diseases, the incorporation of nano-carriers as NDDS in the conventional medicine system is necessary. This review examines the benefits of the nano-drug delivery system, its properties, its drawbacks, forms of nanoparticles, their preparation methods, and various herbal nano medicines. This review further explores how therapeutic benefits can be improved by reducing toxicity and increasing bioavailability.

Published: October 2020

Aristolochia indica is a plant belonging to the family Aristolochiaceae. The medicinal value of A. indica has been known in different system of traditional medicine including Ayurveda. A number of Aristolochia species has been used in herbal medicines throughout the world for the cure of several ailments including metabolic diseases to venomous bites of snake and insects. The current work was executed with an objective to explore the in vitro antimicrobial, anti-fungal and anti-oxidant activity of A. indica. The relevant literature was also pursued for the justification and comparing the resemblances in the results. Aqueous and ethanolic extracts of roots of Aristolochia indica Linn. were tested for their inhibitory effect against 6 bacterial strains [Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Salmonella typhi, Klebsiella pneumoniae & Shigella flexneri] and 3 fungi strains [Aspergillus niger, Aspergillus fumigatus, Candida albicans]. Agar-well method was used for the assessment of in-vitro antibacterial and antifungal activity of A. indica against selected standard bacterial strains. The minimum inhibitory concentration for each extract of various micro-organisms was also measured. Ethanolic extract of A. indica shows Minimum concentration (MIC) value of 50-100 μg/ml against selected bacterial strains which is better when compared to the aqueous extracts. Ethanolic extracts also showed moderate effects against the selected fungal strains, whereas the aqueous extracts failed to exhibit any effect even at higher concentrations.

Published: October 2020

A Didática Profissional teve sua origem na França, surgindo no final dos anos de 1990, tendo como finalidade a compreensão e o desenvolvimento profissional de adultos, envolvendo o ambiente de formação e o ambiente de trabalho. No Brasil, a Didática Profissional surgiu nas pesquisas de Alves (2018a; 2018b; 2018c;2018d; 2019a; 2019b). Objetivou-se com esse estudo apresentar uma breve reflexão acerca do desenvolvimento profissional, envolvendo o ambiente de formação e o ambiente de trabalho, visando avaliar a importância da DP na/para a formação do professor de matemática que atua na educação básica. Para tanto, apresentou-se uma reflexão teórica sobre a temática a partir de pesquisas já realizadas sobre o tema, e mostrou-se algumas reflexões sobre as relações da DP na prática pedagógica de sala de aula de matemática escolar. Realizou-se buscas em bancos de dados de periódicos nacionais e internacionais sobre o tema para dar maior vazão a nossa investigação. Também apurou-se depoimentos de sujeitos in lócus de formação. Os artigos selecionados, bem como, os depoimentos, proporcionaram maior reflexão sobre as análises, e possibilitaram inferir que sem a dialética entre a relação do ambiente de formação e do ambiente de trabalho, o docente se afasta da realidade de sua didática. Considerando esse tema relevante, almejou-se propor ampliar essa discussão em nível científico mais aprofundado.
Electricity savings and greenhouse gas emission reductions from global phase-down of hydrofluorocarbons

Published: October 2020

Abstract. Hydrofluorocarbons (HFCs) are widely used as cooling agents in refrigeration and air conditioning, as solvents in industrial processes, as fire-extinguishing agents, for foam blowing, and as aerosol propellants. They have been used in large quantities as the primary substitutes for
ozone-depleting substances regulated under the Montreal Protocol. However, many HFCs are potent greenhouse gases (GHGs) and as such subject to
global phase-down under the Kigali Amendment (KA) to the Montreal Protocol. In this study, we develop a range of long-term scenarios for HFC
emissions under varying degrees of stringency in climate policy and assess co-benefits in the form of electricity savings and associated reductions
in GHG and air pollutant emissions. Due to technical opportunities to improve energy efficiency in cooling technologies, there exist potentials for
significant electricity savings under a well-managed phase-down of HFCs. Our results reveal that the opportunity to simultaneously improve energy
efficiency in stationary cooling technologies could bring additional climate benefits of about the same magnitude as that attributed to the HFCs
phase-down. If technical energy efficiency improvements are fully implemented, the resulting electricity savings could exceed 20 % of future
global electricity consumption, while the corresponding figure for economic energy efficiency improvements would be about 15 %. The combined
effect of HFC phase-down, energy efficiency improvement of the stationary cooling technologies, and future changes in the electricity generation fuel
mix would prevent between 411 and 631 Pg CO2 equivalent of GHG emissions between 2018 and 2100, thereby making a significant
contribution towards keeping the global temperature rise below 2 ∘C. Reduced electricity consumption also means lower air pollution
emissions in the power sector, estimated at about 5 %–10 % for sulfur dioxide (SO2), 8 %–16 % for nitrogen oxides
(NOx), and 4 %–9 % for fine particulate matter (PM2.5) emissions compared with a pre-Kigali baseline.
