Fabrication and Characterization of Non-Conventional Starch Based Biofilms Employing Different Plasticizers
Authors: Laha Sutapa , Chatterjee Annalakshmi
Published: April 2024

Increasing stress on environmental awareness has promoted the use of alternative strategies for common petrochemical based plastic sources to environmentally friendly biofilms and packaging materials. Food by products and underutilised indigenous plants sources are rich in biopolymers which can naturally decompose. The present study focusses on preparations of bioplastics from unconventional starch sources of litchi seed and churkha tuber as novel initiative to combat environmental pollution along with valorisation of undervalued plant sources and agrobased wastes. Ternary blend films of poly vinyl alcohol, starch, plasticizers like (glycerol, sorbitol, mannitol, propylene glycol, polyethylene glycol), citric acid prepared by casting technique produced best result. Comparative study of test samples (TH11, TH12, TH13, TH14 etc) with standardized thin films (TH1, TH2, TH3 etc.) showed variation in appearance, water activity, thickness, since the starch differ in their compositions, gelatinization and gelation time and temperature. High amylose containing litchi seed starch forms firm and more flexible films in comparison to low amylose containing churkha tuber starch. Maximum hygroscopicity was recorded in case of TH1 (77.4%) while thickness was maximum in case of TH12 (0.18 mm). Micro structural analysis clearly showed the nature of crosslinking between starch molecule and different plasticizers. The sensory analysis of food packed with the best among the formularized thin films showed mild change in taste while the other parameters remain same as normal. Better acceptability was in case of TH12 wrapped food rather than TH1. Thus, fabrication of biodegradable packaging is considered as the most sustainable alternative for food preservation.

Authors: Jha Ayush , Shrestha Rima , Khadka Anupa , Wagle Ashmita
Published: April 2024

Introduction: Oral isotretinoin remains the most clinically effective anti-acne therapy. However, a myriad of adverse effects are associated with isotretinoin use. Elevated liver enzymes and an altered lipid profile are well documented side effects of prolonged oral isotretinoin usage.
Objectives: To assess the alteration in liver enzymes and lipid profiles of acne patients on isotretinoin therapy.
Materials and Methods: The current prospective hospital based study, was carried out from September 2022 to December 2023, and included 150 patients with acne vulgaris on isotretinoin therapy. All consenting patients were then subjected to a detailed history and clinical examination. Subsequently, baseline Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Triglyceride (TG), Low density Lipoprotein (LDL), and High density Lipoprotein levels (HDL) levels were measured. Patients were then started on oral isotretinoin therapy at conventional dosages. Levels of ALT, AST, TG, LDL and HDL were repeated at 3- month and 6- month follow-up visits. A self-designed proforma was used to collect all relevant data. The collected data was analyzed as per standard statistical protocol. Repeated measures analysis of variance was used to compare means between 3 groups (baseline, 3-month, and 6-month values). Results with a p<.05 were considered statistically significant.
Results: The mean age of patients was 22.31(±SD 4.44) years. Females comprised the majority of our study subjects (n = 95; 63.33%). Levels of Alanine (F2,226=30.73, p<.0005) and Aspartate transaminase (F2,232=13.13, p<.0005) were increased significantly at 3 and 6 month follow up visits. Levels of TG were, also, increased significantly at follow up visits (F2,239=14.45, p<.0005). Similarly, levels of low density lipoprotein increased significantly when compared to baseline levels (F1,215=38.43, p<.0005). High density lipoprotein levels were decreased significantly when compared to baseline levels (F1,209=105.83, p<.0005).
Conclusion: Our study has highlighted the significant alterations that occur in liver function tests and lipid profiles in patients on isotretinoin therapy.

Authors: Adhikari Prabin , Singh Rasu
Published: April 2024

Coronavirus disease 2019 (COVID-19) infection may induce thyroid dysfunction as Coronavirus 2 (SARS-CoV-2) can invade the human tissue cells through the cell receptor of angiotensin-converting enzyme 2 (ACE2), expression of which is high in thyroid tissue. The aim of the present study was to assess the subclinical hyperthyroidism post-COVID-19 effects on thyroid function in patients without history of thyroid disease after complete recovery from mild-to-severe COVID19 and find the prevalence of subclinical hyperthyroidism. A descriptive cross-sectional study was conducted in the Department of Internal Medicine, of tertiary care center from September 2022 to February 2023 after obtaining ethical approval from the Institutional Review Committee of Nepal Medical College (Ref. No.: 15-079/080). Convenience sampling method was used among patients who met the eligibility criteria. Point estimate at 95.0% confidence interval were calculated along with frequency and proportion for binary data. Out of 38 patients, 34 (89.5%) had thyroid dysfunction. Among them, 7 (20.6%) had subclinical hyperthyroidism, 2 (5.9%) had thyroiditis and 1 (2.9%) had Graves’ disease. Those who had thyroid dysfunction, 10 (29.4%) people were diagnosed with hyperthyroidism. The hyperthyroidism among COVID-19 patients is a common finding and subclinical hyperthyroidism was seen in 20.6% of patients post COVID-19. Therefore, while managing COVID-19, patients’ thyroid profile should be considered.

In patients undergoing fixed orthodontic therapy, favorable conditions for plaque stagnation as well as difficulty in performing usual oral hygiene measures have been associated with poorer periodontal health among orthodontic patients. So this study aims to assess the effect of the duration of fixed orthodontic treatment on presence of gingival enlargement in adolescents and young adults. This cross sectional descriptive study was conducted in the dental hospital of Nepal Medical College Teaching Hospital. Patients under fixed orthodontic therapy for at least 3 months were examined for the presence of gingival enlargement (GE). Demographic variables and the details of duration of the fixed orthodontic therapy was recorded along with presence of gingival enlargement and its grading. The oral hygiene habits like frequency of brushing, use of interdental cleaning aids were recorded along with plaque index. Gingival enlargement was present in 204 (63.7%) out of total 320 patients taken, among which 124 patients (38.8%) had gingival enlargement of score 1 and 80 (25.0%) patients had gingival enlargement of score 2. Gingival enlargement was observed in 101 (73.2%) in 20-30 years old patients which was more prevalent in this age group. Oral hygiene habits like frequency of brushing and use of interdental aids also seem to affect the occurrence of gingival enlargement in patients. Among those who were undergoing orthodontic therapy for more than 2 years, 48 (82.8%) had presence of gingival enlargement. Mean of plaque index was seen to be statistically associated with presence of gingival enlargement. Thus, this study showed that the duration of orthodontic treatment duration significantly influenced the occurrence of GE. Therefore, oral hygiene instructions and motivations should be reinforced for patients undergoing orthodontic treatment.

Authors: Agrawal Subhadra , Munir Shamila Ijaj
Published: April 2024

To compare the efficacy and safety of intrauterine balloon tamponade with uterovaginal roll gauze packing in patients presenting with primary postpartum hemorrhage after normal vaginal delivery. This randomized controlled trial, conducted at Department of Obstetrics and Gynecology, Lady Willingdon Hospital, Lahore, from December 2015 to November 2016. Two hundred and twelve patients presenting with primary postpartum hemorrhage who did not respond to medical treatment following normal vaginal delivery were included. They were randomly divided in two groups. The first group underwent balloon tamponade using condom and second group underwent intrauterine packing using roll gauze. Both interventions were removed after 24 hours. All females were kept under observation with antibiotic coverage in ward to prevent infection. If bleeding was stopped within 15 minutes and the patient remained hemodynamically stable, then efficacy was labeled and if no complications occur while applying or removing, safety was labeled. Mean age group of women using balloon tamponade and intrauterine packing was used was 28.25±4.672 and 28.30±4.613 years. The mean gestational age of patients using balloon tamponade and intrauterine packing was 38.57±1.36 and 38.63±0.62 years. Mean blood loss in patients using balloon tamponade and intrauterine packing was 600.28±25.338 and 699.21±70.176 ml. Efficacy of intrauterine packing was 94 (88.7%) and balloon tamponade was 104 (98.1%). Safety of intrauterine packing was 83 (78.3%) and that of balloon tamponade was 97 (91.5%). Thus, treatment of balloon tamponade was more effective and safer than intrauterine packing in female presenting with postpartum hemorrhage after normal vaginal delivery.

Authors: Ghimire Lata , Banjara Megha Raj , Hussen Abdulla Abdelkodose Mohammed
Published: April 2024

Introduction: Staphylococcus aureus, recognized as an opportunistic pathogen, is frequently implicated in diverse human infections. Managing multidrug-resistant S. aureus poses a significant challenge in the clinical sector. Beyond B-lactam antibiotics, healthcare practitioners commonly prescribe Glycopeptides, Tetracycline, Quinolones, and Macrolide-Lincosamide-Streptogramin B antibiotics as alternative treatments for such infections. Consequently, this study was undertaken to evaluate the susceptibility of multidrug-resistant S. aureus to tetracycline in clinical samples.
Methods: The study spanned 15 months, from March 2020 to May 2021, during which clinical samples were collected from three distinct hospitals in Kathmandu-Dirghayu Guru Hospital, Chabahil; Bhaktapur Cancer Hospital, Bhaktapur; and Shankarapur Hospital, Jorpati. Sample processing and laboratory work were conducted in the Microbiology Laboratory of Dirghyau Guru Hospital to assess the prevalence of different multidrug-resistant (MDR) phenotypes among S. aureus and their correlation with Methicillin resistance. The study included 266 isolates of S. aureus, and Methicillin resistance was determined using the Cefoxitin disc diffusion method.
Results: Among 2004 clinical samples processed, 266 (13.27%) isolates were S. aureus. The multidrug resistant strain isolated from Outpatient department was 56.84% (54/95) and from inpatient department, the data was 43.15% (41/95). Among the 266 S. aureus, 28.94% Methicillin resistant S. aureus (MRSA) and 71.05% Methicillin sensitive S. aureus (MSSA) isolates were detected. Tetracycline resistance was found in 9.8% of total S. aureus isolates whereas 27.36% (26/95) among multidrug resistant S. aureus isolates. Resistance to Tetracycline was higher in MRSA as compared to MSSA.
Conclusion: The detection rate of MRSA emphasizes the urgency to improve healthcare practices to control the spread of MRSA infections. Tetracycline can be used as a viable alternative antibiotic for combating S. aureus infections, particularly in Kathmandu.

Published: April 2024

The research aims to investigate how Work-Life Balance Practices act as catalysts for Job Engagement and as effective measures in reducing Turnover Intention. By examining these dynamics, the study seeks to provide insights into the mechanisms through which organizations can enhance employee commitment and well-being while mitigating turnover risks. Methodology – A quantitative study was conducted. The data was collected by distributing questionnaires to 233 executive employees in Infopark, Kochi. Research Findings - Interestingly, the study found a link between work-life issues and intentions to leave one's job and to engage in it. Employee inclination to leave is also connected with job engagement.  Originality – WLB, work engagement, and turnover intention are the three study variables that are all holistically related. Organisational inferences in the Kochi environment - Work-life balance (WLB) initiatives must be put into place inside companies in order to promote employees' well-being, which will eventually increase engagement and retention. These results, which were obtained from Malaysian executives, provide practitioners with practical advice on how to create a supportive work environment. Research Limitations and Implications - The majority of the sample population consisted of individuals from the millennial generation, potentially introducing variances in their perceptions of work-life balance compared to those of more mature adults.

As one of the most significant contributors of plastic waste in the world, plastic waste pollution in Indonesia's oceans is an example of the dangers caused by plastic waste to human health, the environment and marine biota. The aims of this research are: 1) to analyse the responsibilities of local governments regarding the management of plastic waste which damages marine biota in the Kalaki Beach Area, Bima Regency. 2) Analyzing the implementation of the Bima Bay area's implementation of plastic waste handling by the Bima Regency Government. The type of research used is empirical legal research with a legislative approach, a conceptual approach and a legal sociology approach. The technique for collecting legal materials and data was carried out using interviews and document study methods. The research results conclude that the Regional Government's responsibility is based on UUPPLH, provincial governments, and district/city governments, which have the authority to form environmental management institutions that carry out management and assessment of the environment. Two steps can be taken in handling this: preventive steps, which can be taken by managing waste, building a waste bank, planting mango trees, providing rubbish bins, and carrying out outreach activities. Repressive steps can be taken by imposing sanctions on violators of regulations and also regional cooperation.

La televisión mexicana comenzó a operar oficialmente el 31 de agosto de 1950. La primera transmisión se realizó el 1 de septiembre de ese mismo año a través del Canal 4, frecuencia concesionada a Rómulo O’Farril. Las siguientes concesiones de televisión también fueron otorgadas por el presidente de la república Miguel Alemán, una a Emilio Azcárraga Vidaurreta, el Canal 2, y otra a Guillermo González Camarena, el Canal 5. Los tres canales tenían programaciones muy similares y competían por la publicidad con contenidos de concurso, entrevistas y musicales. Cinco años después, en 1955, los concesionarios de esas frecuencias decidieron fusionarse y conformar Telesistema Mexicano (TSM), antecedente de la actual Televisa.

5. Calidad e impacto de los spots publicitarios en la contienda electoral por el gobierno de Jalisco
Authors: Becerra Zendejas José Ramón
Published: April 2024

Sobre el tema de la política mexicana, una de las discusiones más grandes en los últimos años ha sido la relación de esta con los medios de comunicación y su regulación. La indudable influencia que tienen las televisoras y radiodifusoras en el país —70% de la población se entera de las campañas políticas por televisión y radio—, ha permitido la formación de un sistema de comunicación política con base sobre todo en pequeños mensajes propagandísticos que con frecuencia no son suficientes para lograr una verdadero intercambio de información entre políticos, medios de comunicación y ciudadanos. Aprovechando la coyuntura electoral, se realizó esta investigación con la intención de poner a prueba el sistema de comunicación política y verificar si los spots publicitarios permiten un diálogo público que lleve verdaderamente hacia la democracia.

Authors: Paláu Cardona Magdalena Sofía
Published: April 2024

En 1988 las elecciones federales fueron controvertidas pues el Partido Revolucionario Institucional (PRI) mostró, por primera vez desde su conformación, posibilidades reales de perder las elecciones a la Presidencia de la República. Este hecho marcó el paso de unas elecciones en las que los resultados eran predecibles a otro donde las elecciones eran competidas e inciertas. En dicho contexto se hizo necesario conocer las preferencias de los electores y por ello surgieron los primeros estudios realizados por casas encuestadoras. Esto significa que la historia de las encuestas en nuestro país es relativamente joven, con apenas 25 años de experiencia de diversas empresas encuestadoras en este campo de la política electoral.

D. Mamin — a Siberian or Ural native? Literary evidence of Siberia’s boundaries
Authors: Korshunkov V. A.
Published: April 2024

The article by the historian and local history expert V. Korshunkov examines the Ural component of D. Mamin’s works. The writer’s pen-name (D. Sibiryak [a native of Siberia]) still causes some controversy. So far, any attempts to interpret the choice of the pseudonym have remained purely speculative. The author demonstrates that the pen-name corresponds to the old geographical delineation, almost completely obsolete during Mamin’s lifetime. Specifically, it appears that in the middle of the 19th c., the Ural region was thought to be a part of Siberia (which, in its turn, some hesitated to deem actual Russia). The locals believed that the watershed in the Urals marked the boundary between the ‘Raseya’ Russia and Siberia, effectively making East Ural a region in Siberia, with Mamin-Sibiryak’s birthplace located right by the watershed. The article cites mentions of this fact in artistic writings and memoirs of the 18th–19th cc., for example, in L. Travin’s reminiscences and works of the traveller and ethnographer V. Maksimov. The detailed historical analysis of the material helps discover new facts about Ural in the mid-19th c., as well as gain better understanding of Mamin-Sibiryak’s poetics.
Poetic imagery in L. Tolstoy’s Resurrection [Voskresenie]
Authors: Molnar A.
Published: April 2024

The article examines three principal devices of L. Tolstoy’s poetics in the novel Resurrection [Voskresenie]: metaphorization, contrasts and oppositions, and repetition and rhetorical climax. Repetition of certain fragments marks a turning point in the plot, as well as a return to the true nature of things, with multiple arrangements gradually intensifying to amplify the effect. The use of such devices can be observed in the metaphorization of nature which accompanies transformations of the male and female protagonists, for example, in the description of the garden with lilac bushes and the nightingale, the ice breaking on the river, or a sweltering day on the train and in the city. The repeated images conjure up parallels between the fragments describing the characters’ falling in love and committing a sin, as well as between the scenes of train journeys — to the army and to the prison camp. The characters’ intellectual and spiritual development is expressed through tropes and repetitions of motifs and sounds, which shifts the focus from the ideological to the poetic dimension, and helps create new images that complement the narration’s ideological foundation.
TÜKETİM KÜLTÜRÜNÜN GÖÇ ÜZERİNDE OLUŞTURDUĞU BAŞLICA FAKTÖRLERİN İRDELENMESİ
Authors: Akyıldırım Erol
Published: April 2024

Çalışmada insan olgusu ile isteğin göç etme süreci üzerindeki ilişkinin irdelenmesi amaçlanmaktadır. İnsanın biyolojik yapısı tüketime eğilimli bulunmaktadır. Bu nedenle tüketime yönelik ürün çeşitliliğin artmış olması, tüketim bağlamında ihtiyaç dairesini genişletmektedir. İnsanın tabiatında, ihtiyaç dairesinin hayal dairesi kadar geniş olduğu söylenebilir. Elde edilmeyen istek ve ihtiyaçların, hayal dairesi kadar geniş bir mekânın olduğu düşünülmektedir. Bu durum, arzu ve isteklerin peşinde koşan ve sosyal hareketlilikte bulunan bir birey profilini doğurmaktadır. Tüketim anlamında birey yapay ve yanlış tüketim bombardımanına maruz kalmaktadır. Birey ya da kitleler istek ve ihtiyaç dairelerin kötüye kullanımı hususunda, sosyal medya ve reklam gibi faktörlere maruz kalarak, ihtiyaç fazlası ürün tüketmektedir. Kitle iletişim araçlarındaki gelişmeyle birlikte globalleşen dünyada, tüketim anlamındaki ürünlerde çeşitliliğin artış göstermesi ve bireyin bu ürünlere ulaşma isteği, beraberinde bireysel ve kitlesel hareketliği doğurmaktadır. Tüketim hususunda bireyin sınırlı olmayan arzuları ve doymayan biyolojik yapısı, tüketim anlamında sürekli eylem gerçekleştirecek yapıda olduğu görülmektedir. İnsan olgusunun bu yapısı da göç sürecini sürekli tetiklemektedir. Özellikle de kent merkezlerinde tüketim mekânlarının yoğunlaşması, bireysel ve kitlesel anlamda göç hareketliğin oluşumuna yol açmaktadır. İhtiyaç alanı sosyal yapının tüm katmanları için göreceli bir kavram olduğundan, göç sürecinin de bu kapsamda değişkenlik ve süreklilik göstereceği görülmektedir. Sonuç olarak tüketim olgusu insanın hayal ve nazar dairesi kadar geniş olduğundan daima genişleyen ve kapitalist gelişmenin kötüye kullandığı bir mekân olarak görülmektedir.

Published: April 2024

Dünya ve İslâm kültür mirasında büyük bir yere ve öneme sahip olan Osmanlı Devleti’nin bu önemli varlığının sebeplerinden bir tanesi de İstanbul gibi dünya kültür tarihinde eşsiz bir yere sahip olan bir şehre sahip olmasıdır. Osmanlılar, fethettikleri andan itibaren diğer yerlerde olduğu gibi İstanbul’da da büyük bir îmar faaliyetine girişmişlerdir. Bu faaliyetin en önde gelen unsuru camiler olmuştur. Müslüman olmaları ve ayrıca İslâm hâlifeliğini üzerlerinde bulundurmaları hasebiyle Osmanlılar, camilere daha da önem vermişlerdir. Öyle ki bu önem devletin en tepesinde bulunan padişaha kadar sirayet etmiştir. Başta namaz olmak üzere dinî vecibelerin yerine getirildiği ve bunun yanında dinî, sosyal ve kültürel daha birçok uygulama için elverişli olan camilerin bu özelliğinden çok iyi bir şekilde istifade eden Osmanlı padişahları, camiyi Hz. Peygamber (SAV) zamanında olduğu gibi âdeta hayatın merkezine yerleştirmişlerdir. Dolayısıyla cami hayatla iç içe olmuş ve namaz dışındaki birçok dinî iş, işlem ve uygulama camide yapılır olmuştur. Biz de bu çalışmada öncelikle bu uygulamaların yapıldığı İstanbul’daki dört büyük selâtin camisini kısaca tanıttıktan sonra, camide yapılmakta olan bu uygulamalardan olan bazı dinî merasimleri ve bu merasimlerde uygulanan dinî mûsikî formlarını ele almaya çalıştık.

Authors: Вантеева Ю.В.
Published: April 2024

В рамках методики ландшафтного планирования впервые проведена оценка средорегулирующих функций геосистем бассейна р. Бол. Мамай (юго-восточное побережье оз. Байкал, хр. Хамар-Дабан, Бурятия). Основой для исследования послужила ландшафтно-типологическая карта на уровне групп фаций в масштабе 1: 50 000. В качестве количественных показателей климаторегулирующей функции геосистем использованы данные о запасах органического углерода в древесной фитомассе и верхних гумусовых горизонтах почв на глубине 0–5 см. Для оценки стокоформирующей и эрозионнорегулирующей функций использовались данные о запасах древесной фитомассы и рассчитанные по ЦМР показатели накопления стока и LS-фактор. С применением методов геоинформационного анализа данных и ландшафтно-интерпритационного картографирования произведена оценка рассматриваемых функций для каждого типа геосистем. Составлена матрица значимости геосистем для обеспечения средорегулирующими функциями. В результате выявлено, что наибольшее распространение (30,6 %) на территории водосборного бассейна р. Бол. Мамай получила горная темнохвойная тайга и субальпинотипные горно-луговые геосистемы (26,2 %). Долинные геосистемы занимают около 12 %. Наибольший вклад в средорегулирование вносят коренные темнохвойные (пихтовые, елово-пихтовые и пихтово-кедровые) леса, получившие распространение как в горной части бассейна, так и в предгорьях, однако в последней их доля значительно сокращена вследствие антропогенной деятельности. Разработанные критерии оценки средорегулирующих функций геосистем могут быть применены и для других территорий.

Published: April 2024

The peculiarities of origin, morphological and genetic varieties and structural and dynamic interrelations of dry valley landscapes of the Cretaceous south of the Central Chernozem Region are considered. Modern ideas about genesis, morphology, development and landscape structure of sukhodols are presented. Paradynamic interrelations of structural elements of basin landscape systems are emphasized. The necessity of taking into account landscape specificity of dry lands when solving the problems of nature management and optimization of landscape-ecological situation in the Cretaceous south of the Central Chernozem Region is emphasized. As an example, we analyzed the component, territorial and altitudinal organization of natural complexes of a large sukhodols of the Kuvshin dry valley located in the Podgorensky district of the Voronezh Region. The main factors of landscape differentiation are established, among which are peculiarities of morpholithogenic base, character of biostrom development, modern economic use. The problems of identification of local landscape boundaries and approaches to their solution have been noted. Based on the results of the research, 7 families and 45 species of landtypes, as well as altitudinal landscape layers and sub-layers were identified within the valley. Recommendations on changing the conservation status of the territory are given.

В статье приведены геохимические исследования отложений в долине р. Березовка (Красноярская лесостепь), непрерывное накопление которых происходило с конца позднего плейстоцена и весь голоцен (начиная с 20833 ± 519 кал. лет назад). Определены характер и условия формирования отложений левобережной террасы р. Енисей Красноярской лесостепи на основе анализа общей характеристики и особенностей макроморфологического строения. Приведены данные детального геоботанического описания пробной площадки лесостепных ландшафтов территории Красноярской котловины, наименее подверженной антропогенному воздействию, и спорово-пыльцевых спектров (СПС) поверхностных проб для оценки отражения состава растительности в спектрах. Для установления достоверности полученных данных использован коэффициент Дэвиса, который дает возможность рассчитать отношение процентного содержания пыльцы вида в спектре к проценту участия этого вида в составе фитоценоза. Было установлено, что между составом растительного покрова лесостепных ландшафтов и составом спорово-пыльцевых спектров существует прямая корреляция, что дает возможность интерпретировать данные спорово-пыльцевого анализа для реконструкций палеоклиматов и палеоландшафтов голоцена. Представлены результаты малакофаунистического анализа разреза поймы р. Талая, заложенного в северо-западной части Красноярской котловины (56029´с.ш., 93045´в.д., абсолютная вы-сота ― 213 м) на пойме правого берега одноименной реки, в 1 км на северо-восток от д. Талая.
Весеннее развитие черемухи обыкновенной как индикатор временных состояний ландшафтов (Свердловская область)
Authors: Янцер О.В.
Published: April 2024

В статье представлены результаты исследования весеннего развития черемухи обыкновенной при проведении Единого фенологического дня 15 мая на территории Свердловской области за 2012–2023 гг. Изучение сезонного состояния вида при помощи описательного метода позволило определить географические закономерности наступления фенологических фаз и скорости продвижения явления в пространстве в пределах природных зон и подзон в зависимости от факторов окружающей среды. Выявлено более раннее развитие черемухи на юго-востоке и юго-западе области, далее фронт явления продвигается на север и северо-запад. Различия между северными и южными районами территории, в среднем, составляют 6–7 баллов. В результате наблюдений получена характеристика сезонного развития объекта, индицирующего состояние природных комплексов в краткой математической форме. Максимальное опережение развития выявлено в лесостепной зоне Русской равнины и Западной Сибири в границах исследуемого региона. В горных районах области явления наступают с заметным отставанием в 6 баллов по сравнению с равнинными. Скорость прохождения явления в разных под зонах колеблется от 0,8 до 3 баллов/100 км. Опыт такого рода многолетних исследований для других районов страны может помочь выявить тенденции влияния изменений климата на адаптационные механизмы отдельных видов растений-феноиндикаторов.

Биологическая активность лекарственного растительного сырья и фитопрепаратов обусловлена комплексом биологически активных веществ и химических элементов. Исследование влияния условий призрастания на состав, содержание химических элементов в лекарственных растениях, лекарственном растительном сырье является актуальным. Особый интерес вызывает исследование закономерностей в распределении химических элементов в лекарственных растениях, лекарственном растительном сырье и возможность использования выявленных закономерностей для установления подлинности и чистоты сырья. Объект нашего исследования — листья березы, собранные в экологически чистой зоне и в зонах с различной степенью антропогенной нагрузки. Состав и содержание элементов анализировали методом ИСП–МС (масс-спектрометр ELAN DRC-е ICP-MS, оптико-эмиссионный спектрометр Agilent 715 ICP–OES). Статистическая обработка результатов химического анализа проведена в программе Microsoft ® Excel 2010. Сопоставление концентраций 60 элементов проводили с применением метода наименьших квадратов. Сравнительный анализ логарифмов концентраций в листьях березы, собранных из мест произрастания, различающихся по степени антропогенной нагрузки, показал сильную корреляционную связь между ними (r=0,99; R2=0,9). Диаграмма, отражающая периодическую зависимость логарифма концентраций химических элементов, представляет собой элементный профиль листьев березы и может быть использована для установления их подлинности и чистоты.

Neste estudo, relatamos a importância do controle de qualidade do leite bovino industrializado em caixinha no quesito identificação dos rótulos das embalagens quanto a porcentagem de gordura e níveis de proteínas para os tipos integral, semi-desnatado e desnatado pela Espectroscopia Raman no Infravermelho Próximo. Os espectros revelaram que o nível relativo de gorduras está de acordo com o rótulo das embalagens, mas o mesmo não ocorre com as proteínas. As bandas relativas às proteínas também decrescem do integral para o desnatado e semi-desnatado. Pode-se concluir que os processos pelos quais o leite é industrializado podem reduzir os níveis de algumas proteínas. Diversas técnicas espectroscópicas como a Técnica Raman têm sido utilizadas para a quantificação e análise de substâncias químicas, uma vez que dispensam qualquer tipo de tratamento prévio das amostras analisadas e se constituem numa ferramenta potencialmente importante para análises químicas, com as vantagens de serem não destrutivas e tornando desnecessária a separação prévia da amostra em seus componentes para posterior análise. Como resultado tem se um menor tempo de análise e redução dos custos.

Published: April 2024

O experimento foi desenvolvido na E.T.E. Dr. Luiz César Couto, localizado no município de Quatá, sendo que as análises foram realizadas no Laboratório de Nutrição Animal da Escola Superior de Agronomia de Paraguaçu Paulista-ESAPP. Os tratamentos avaliados foram quatro níveis de uréias adicionadas à cana-de-açúcar hidrolisada. O delineamento experimental utilizado foi inteiramente casualizado com cinco repetições. O acréscimo de uréia na cana hidrolisada, mostra-se uma técnica interessante, uma vez que estaremos melhorando a digestibilidade da cana-de-açúcar pela ação da cal e corrigindo o teor de proteína da cana, que é conhecidamente baixo.
