As the focus in forestry is moving from timber production to prioritized economic benefits and better integration of ecological-social functions, practical forest management is shifting towards promoting diverse stand structures. Promoting stand structural heterogeneity requires accurate and profound evaluations of spatial stand structure that are generally not provided during conventional forest inventories. In this paper, different indices describing the heterogeneity of the stand and the spatial arrangement of trees, including their size, condition and species were assessed. Indices were applied to the inventory data collected from the Estonian Network of Forest Research Plots. The results show that the studied structural indices are useful in assessment of Estonian forest stands. The practical importance of structural indices will increase in future as there will be a need for methods for characterizing forest stand structural diversity at a large scale, for example, derived from high-resolution remote sensing data.

Penelitian bertujuan untuk mengetahui pertumbuhan generatif Asystasia pada berbagai dosis dan waktu dekomposisi pupuk kotoran kambing. Penelitian menggunakan rancangan acak lengkap (RAL), pola faktorial. Faktor pertama adalah waktu dekomposisi yang terdiri dari 3 taraf, yaitu waktu dekomposisi 4 minggu, 2 minggu dan tanpa dekomposisi. Faktor kedua adalah dosis pupuk kotoran kambing dengan 4 taraf, yaitu tanpa pupuk 0 ton ha-1, 10 ton ha-1, 20 ton ha-1, dan 30 ton ha-1. Setiap kombinasi perlakuan diulang empat kali, sehingga pot yang digunakan keseluruhan adalah 48. Variabel yang diukur adalah waktu berbunga pertama kali, total produksi biji, berat biji per 100 biji, jumlah kelopak biji, dan dimensi ukuran biji (panjang, lebar dan tebal). Hasil penelitian menunjukkan bahwa tidak terjadi interaksi diantara kedua faktor pada semua variabel yang diukur. Penambahan dosis pupuk kotoran kambing sebanyak 10 ton ha-1 secara nyata memperpanjang waktu berbunga Asystasia pertama kali dibandingkan kontrol, namun demikian pengaruh waktu dekomposisi tidak menunjukkan perbedaan yang nyata. Penambahan dosis pupuk 10 to ha-1 secara nyata dapat meningkatkan jumlah produksi biji per pot, tetapi juga secara nyata menurunkan berat biji per 100 biji dibandingkan kontrol. Dimensi biji (panjang, lebar dan tebal biji) tidak dipengaruhi baik oleh dosis pupuk maupun waktu dekomposisi. Dari penelitian ini dapat disimpulkan bahwa penambahan dosis pupuk kotoran kambing 10 ton ha-1 dapat menunda waktu berbunga, meningkatkan jumlah biji, tetapi menurunkan berat biji Asystasia.

Peculiarities of the filtration process of liposomal emulsion for the production of eye drops based on a peptide complex
Authors: Kruglov Ye. M. , Borshchevskiy G. I.
Published: February 2023

Liposomes are increasingly being studied and implemented as drug delivery systems in the form of eye drops. An important stage in the production of a liposomal preparation in the form of eye drops is the stage of sterilization filtration before filling the medicinal product into a container for final dosage. It is assumed that liposome components interact with the membrane and clog it due to their unique physicochemical properties. Therefore, a deeper understanding of the sterilization filtration of liposomes is needed to make appropriate decisions regarding the choice of filters for sterilization.Resistance and permeability values calculated from the Darcy equation are well suited for comparing different filter membranes or process parameters.
Aim. To substantiate the choice of optimal brands of filter membranes and parameters of the liposomal emulsion filtration process for the production of eye drops based on a peptide complex.
Materials and methods. The study object was a liposomal emulsion for the production of eye drops based on a peptide complex. A prepared liposomal emulsion of eye drops based on a peptide complex and membrane filters of various brands were used for filtration. Filtration tests were performed on a Zero-T scaling unit manufactured by Sartorius, Germany. For all measurements, the filtrate weight was controlled using a balance. Filtration experiments were evaluated using Zero-T 2.0 software from Sartorius Stedim Biotech, Germany. At the first stage, the recorded data of the results was saved to a file. Based on the data obtained using the Excel table processor, the filtration flow J°, the initial resistance of the membrane R°zag and the throughput Ṽ were calculated according to the calculated measurement time: the beginning of T10 % and the end of T80 %.
Results and discussion. According to the results obtained, the optimal brands of sterilizing membranes were determined; it was shown that by increasing the pressure drop, the volumetric throughput was significantly improved by more than 18 times (from 0.7 to 4.1 bar), and in another experiment – by more than 10 times (from 0.3 to 2.1 bar). In addition, the benefit of using a higher pressure drop to filter liposomes through various sterilizing membranes was shown.
Conclusions. The obtained values of the initial resistance of the membrane showed that the geometrical aspects and properties of the material of the Supor® (Pall) and Sartopore 2® (Sartorius) membrane brands have a lower ability to block the membrane during filtration and provide the filtration resource due to greater throughput. It has been also shown that the use of a higher pressure drop increases the productivity of the process.
A methodical approach to the multi-criteria selection in the pharmaceutical technological research with quantitative factors
Authors: Kutova O. V. , Sahaidak-Nikitiuk R. V.
Published: February 2023

Aim. To analyze the existing methods for solving multi-criteria optimization problems with quantitative factors and consider the expediency of their application in the pharmaceutical technological research.
Materials and methods. The theoretical and empirical methods, as well as scientific data on multi-criteria optimization methods were used in the research.
Results and discussion. It has been found that when conducting the research with quantitative factors the statistical methods for processing the results of experiments are used. It has been determined that the regression analysis allows us to present the dynamics of changes in the pharmacopoeial characteristics studied from variable quantitative factors in a compact form. It has been found that regression equations enable the researcher to effectively search for optimal conditions for conducting technological operations and are local criteria for finding the optimal solution. It has been proven that the need to optimize several criteria simultaneously when developing the technology of a medicinal product allows considering the tasks of multi-criteria selection in the pharmaceutical research as a special class of decision-making problems that are on the verge between the research of operations for well-structured quantitative situations and decision-making tasks, which methods of solving differ.
Conclusions. To determine the optimal solution in the course of the pharmaco-technological development, a method for finding an ideal point has been proposed as a synthesis of mathematical calculations and decision-making procedures by a researcher. The search is conducted in the range of acceptable values of variables and determines their totality, which is able to provide a set of values of pharmaco-technological criteria that is closest to the optimal option determined by the researcher. This approach involves preliminary solution of single-criterion optimization problems for each individual criterion and reduction of all to a mathematical form that determines the minimum deviation of the objective functions obtained from the optimal values.

Authors: Vlasova I. K. , Botsula I. V. , Kireyev I. V. , Koshovyi O. M.
Published: February 2023

Inflammation accompanies huge numbers of diseases. In case of inflammation, non-steroidal anti-inflammatory drugs are used, but they have a number of side effects and disadvantages. In turn, medicines based on the medicinal plant raw material that exhibit the anti-inflammatory activity, on the contrary, are underestimated and insufficientlystudied. An interesting object in this direction is large cranberry leaves of Ericaceae family.
Aim. To study the chemical composition and the anti-inflammatory activity of extracts from large cranberry leaves to establish the prospect of creating new drugs with the anti-inflammatory activity.
Materials and methods. The study objects were dry extracts from large cranberry (Oxycoccus macrocarpus (Ait.)) leaves. The chemical analysis of the extracts was studied by TLC and spectrophotometry methods. The anti-inflammatory activity of the extracts was studied on the model of carrageenan edema.
Results and discussion. Hyperoside and chlorogenic acid were identified in the extracts. In the dry extract from large cranberry leaves, the content of the total amount of derivatives of hydroxycinnamic compounds was 11.60 ± 0.05 %, and in the modified extract – 3.09 ± 0.05 %. The anti-exudative activity was more pronounced in the group of animals that received the cranberry extract with arginine in the dose of 100 mg/kg.
Conclusions. Identification and the quantification of biologically active substances in large cranberry leaves extracts have been carried out; their anti-inflammatory activity has been determined.

Authors: Goncu Mehmet Tugrul , Pala Arda Aybars , Sunbul Sadik Ahmet , Engin Mesut , Tatli Ahmet Burak , Seker Ibrahim Burak
Published: February 2023

Objective: Pectus excavatum is a deformity that occurs at the lower part of the sternum of the thorax, including the xiphoid process. Deformity generally causes cosmetic and psychosocial problems. Life-threatening conditions may ensue in patients with severe deformities. Ravitch surgery and Nuss's minimally invasive surgical procedures are the main procedures for correcting the pectus excavatum. A rare method of pectus excavatum is the stabilization of the sternum by using sternal plates. In this report, we present a case; successful pectus excavatum repair using the sternal plate simultaneously in a 48-year-old male patient who underwent Bentall operation due to ascending aortic aneurysm and aortic valve insufficiency.

Case presentation: The patient was admitted with complaint of dyspnea. Examinations including clinical examinations, echocardiography, computed tomography  and pulmonary tests revealed pectus excavatum, with Haller index&qt;3.5,   reduced forced vital capacity 72% and ascending aorta aneurysm of 5.7 cm and moderate aortic valve regurgitation. The decision  to proceed with simultaneous aortic root and aortic valve replacement with pectus excavatum correction was taken. The operation were performed successfully under cardiopulmonary bypass without complications. Patient was discharged  on 9th postoperative day.

Conclusion: In patients with pectus excavatum deformity who undergo cardiac surgery (in our case ascending aorta and aortic valve replacement) with median sternotomy, simultaneous sternal repair using a sternal plate is safe and preferable because it positively affects cardiac and pulmonary surgical outcomes. Therefore, we recommend simultaneous sternal plate application in patients with pectus excavatum who will have a cardiac operation.

تكمن أهمية البحث في دراسة التوسع المساحي لمدينة بلد وماهي العوامل التي ساعدت على توسع المدينة في اتجاهات معينة وماهي المحددات الرئيسة لعملية التوسع في الاتجاهات الاخرى ، اذ تم التوصل الى مجموعة من العوامل الطبيعية والبشرية المؤثرة في عملية التوسع سواء اكانت عوامل مساعدة او محددة فالعوامل المحددة لنمو المدينة وتوسعها تتمثل بمشروع ري الاسحاقي من الجهة الجنوبية للمدينة ونهر الشطيطة من جهتها الغربية ومرقد الامام السيد محمد من الجهة الشرقية ، فضلاً عن دور الاراضي الزراعية  واثرها كعامل محدد يعيق عملية نمو المدينة وتوسعها ، اذ نجد في بعض الاحيان بأن هناك عوامل طبيعية او بشرية كانت مشجعة لتوسع المدينة تارة لكنها صبحت من العوامل المحددة للتوسع تارةً  اخرى كما هو الحال في وجود مرقد الامام السيد محمد (علية السلام )، كما يهتم البحث في دراسة مشكلة استنفاذ اراضي المدينة اذ لم تعد هناك اراضي خالية وغير مستغلة يمكن للمدينة ان تتوسع باتجاهها لكون اغلب احياء المدينة اصبحت من الاحياء المغلقة وغير القابلة للتوسع نتيجة للنمو العمراني والسكني الكبير للمدينة  في ظل الزيادة الكبيرة المتحققة في حجم السكان نتيجة للزيادة الطبيعية وعامل الهجرة ، اذ كان لأهمية المدينة من النواحي الدينية والاقتصادية والاجتماعية  الاثر الكبير في ذلك  فقد اصبحت من المدن الجاذبة للسكان،  كما تم التوصل الى ان توسع المدينة مر بمراحل متباينة اذ كان توسع المدينة في بداية نشأتها عشوائي ، ثم اصبح نمو المدينة وتوسعها بشكل مخطط منذ عام 1968م اذ تم وضع اول تصميم اساس للمدينة ثم أُلْحق بعدها بعدد من التصاميم والتعديلات وبذلك اصبح توسع المدينة يسير وفق ما مخطط له ، ثم عاد الى العشوائية بعد احداث عام 2003م بسبب سقوط نظام الحكم وغياب سلطة القانون وتجاوز عدد كبير من السكان على اراضي المدينة وعلى الاراضي الزراعية واراضي الاستعمالات الحضرية ، لذا ينبغي العمل على وضع تصميم اساسي جديد للمدينة يحدد الاتجاه الملائم للتوسع بعيداً عن العوامل المؤثرة والمحددات.

Reflection of Iraqi Translator's Invisibility in Translating Israeli News in Digital Journalism
Authors: Al-Jubori Gailan Mahmoud
Published: February 2023

This paper investigates the translators' invisibility in translating certain excerpts collected from a media discourse of three different Israeli digital journalisms in English language to see how the translators hide themselves in such a discourse and to what extent they are influenced by the ideological perspectives towards the Israeli practices against the Palestinians. Translator's invisibility is very significant factor to determine how he/she presents the ideas and views about certain public issue away from the ST writer, taking into account the cultural background of the Target Text (TT) readers. The invisibility is regarded as an indicator of the translator's thoughts and orientation when translates form one language into another language because of the contradictory of the views between Source Text (ST) writer or speaker and the TT reader or listener. In this paper, the invisibility is investigated according to Venuti's model which considers it as a main concern and it is reflected in the translation of the news excerpts when the writers describe the events and what is going in the area. The aim of this  paper is  to show how the translators use stetting's strategies in translating news that adopted  according to the translator's invisibility.

Covid-19 has impacted the health and well-being of children worldwide. The aim of this study was to evaluate parental acceptance of and concerns about vaccinating their children against Covid-19 in Ras Al-Khaimah, United Arab Emirates. The study adopted a cross-sectional design. Parental acceptance of and concerns about vaccinating their children were collected using a structured questionnaire. A total of 366 parents were selected, using purposive sampling from the Emirate of Ras Al Khaimah, during the period of November 2021 to February 2022. Of all, 5.3% (56) of the parents expressed a high level of concern regarding vaccinating their children against Covid-19, while 80.6% (295) expressed a medium level and 4.1% (15) a low level of concern. Parental acceptance was found to be medium and high among 71% (260) and 8.8% (69) of the parents respectively, as opposed to 10.1% (37) who were reluctant (low) to do so. The most important concerns for the low acceptance of Covid-19 vaccination were safety, side effects and effectiveness of the vaccination. The study reveals the need to initiate more targeted interventions to improve the acceptability of vaccines and the acceptance of the parents in order to alleviate the concerns of parents about vaccinating their children against Covid-19.

Published: February 2023

Orbital apex disorders (OADs) are uncommon and they include – orbital apex syndrome (OAS), superior orbital fissure syndrome (SOFS), and cavernous sinus syndrome (CSS). They all share similar etiologies, diagnostic evaluation, and management strategies. These syndromes can occur isolated or combined – where SOFS progresses and develops into OAS or CSS. Combined presentation has been reported with infective etiologies, but no literature is available for neoplasms. OAD secondary to head and neck cancer is exceptionally rare. A 44-year-old male post left hemi-mandibulectomy with modified neck dissection, radiotherapy, and chemotherapy for left retromolar trigone carcinoma presented with complaints of inability to open left eye (LE) and defective vision in the same eye. On examination of LE, visual acuity was 6/24 NIP with complete ptosis, extraocular movements were restricted in all gaze, corneal sensation was diminished, and pupil was 5 mm and not reacting to light. LE fundus examination showed blurring of disk margins. The primary diagnosis was made as OAS. Contrast enhanced-MRI neck showed features suggestive of recurrence with intracranial extend involving left cavernous sinus, orbital apex, and left orbit. Later considering the extend of spread in MRI and the clinical presentation, diagnosis was made to be OAD. The patient was given third cycle of chemotherapy – injection paclitaxel, injection cisplatin, and injection fluorouracil, along with injection dexamethasone. The patient was provided temporary eye crutch glasses and asked to review after 3 weeks for repeat assessment. Although individual syndromes of OAD are rare, they are closely related entity. Hence, it is important to know that SOFS can progress to OAS causing visual dysfunction or to CSS, leading to systemic ailments. Or else, they can present as combined syndromes also.

Published: February 2023

Tuberculous meningitis (TBM) contributes around 5% among extrapulmonary tuberculosis (TB) and it is devastating with significant morbidity and mortality. It is associated with high frequency of neurologic sequelae and mortality. TBM has a subacute presentation with non-specific clinical signs making difficulty in early diagnosis. We report a case presenting with only ocular symptoms and no typical signs of meningitis with normal brain imaging. Real time PCR and other nucleic acid amplification methods are increasingly used for detection of mycobacterium TB from cerebrospinal fluid. When recognized early and treated promptly with appropriate anti-tuberculous medication, prognosis is good.

Authors: F Afrian , Okfalisa
Published: February 2023

A Decision-Making in determining the project tender winner becomes a significant challenge in the procurement stage, thus it is very vulnerable to administrative errors, corruption, and nepotism. Therefore, a recommendation system becomes a new problem solving in order to increase the information transparency, the company’s opportunity to win, the fraud minimization, and the community complaint on the project tender. The system is developed using the analysis of Fuzzy MOORA to calculate the significant consideration of six criteria, including the administration, the qualifications, the technical experience, the proposed price, the number of projects, and the size of the project based on the winning budget. Herein, 20 companies were acted as alternatives in applying and testing the recommendation tender system. As a result, Blackbox and User Acceptance Test (UAT) of this application from ten staffs of the Working Selection Group (POKJA) at the Bureau of Procurement of Goods and Services (PBJ) of Riau Province found that the entire modules and functions of the system run well. Meanwhile, UAT scores of 87.6% states that this application can assist the POKJA’s staffs in objectively selecting the tender winner. In addition, the sensitivity test analyzes the possible increasing of the weighting criteria, viz., C3 (technical experience) and C4 (price) can improve the quality rankings of alternatives up to 79.16%. Thus, this result enhanced the efficacy of Fuzzy MOORA approach in providing a better recommendation analysis.
