Orthodontic management of anterior disc displacement without reduction
Authors: Alsulaimani Fahad F. , Alswajy Wafa A.
Published: May 2022

This article presents a novel idea for managing patients with anterior disc displacement without reduction that often develops in susceptible patients during routine orthodontic treatment. The patient was a 24-year-old male who presented with class I right molar and canine relationship and class III left molar and canine relationship on a class I skeletal base, complaining of bimaxillary crowding. The case was treated with fixed orthodontic appliance with maxillary expansion and unilateral mandibular extraction to eliminate the mandibular crowding. Due to a life crisis, the patient developed anterior disc displacement on the right joint. A maxillary occlusal splint was fabricated to reduce the symptoms and attempt to recapture the disc; however, this attempt failed. An attempt was then made to recapture the disc using occlusal pivots and elastics. The disc was eventually recaptured, and the patient resumed normal jaw function and mouth opening. This case report aims to demonstrate a new way to achieve stable occlusion in a patient who sustained disc displacement.

Published: May 2022

Ingestion is the entry of a substance into the human organism, which occurs by taking it through the mouth into the gastrointestinal tract. One of the adverse events that may happen during the course of an orthodontic treatment is the ingestion of orthodontic appliances. The present review aims to investigate the literature regarding the ingestion of orthodontic appliances. An electronic search was carried out in order to identify case reports of ingestion of foreign objects related to orthodontic treatment in PubMed, Scopus, and Web of Science until July 2019.Nineteen articles were retrieved. In these articles, ingestion had occurred inadvertently, due to patients’ or orthodontists’ errors. Some of the most commonly ingested appliances were molar bands, segments of wire, and expansion keys. It is likely that patients with a specific medical background are more prone to ingestion of orthodontic appliances. Special precautions need be taken in order to avoid such incidents. These precautions are analyzed in three categories: general, those related to fixed appliances, and those related to removable appliances.

Published: May 2022

PURPOSE:

To develop a new dry eye syndrome (DES) animal model by injecting mitomycin C (MMC) into the lacrimal glands (LGs) of rabbits evaluated by clinical examinations.

MATERIALS AND METHODS:

A volume of 0.1 mL of MMC solution was injected in the LG and the infraorbital lobe of the accessory LG of rabbits for DES induction. Twenty male rabbits were separated into three groups, the control group, and different concentration of MMC, (MMC 0.25: 0.25 mg/mL or MMC 0.50: 0.5 mg/mL) were tested. Both MMC-treated groups received MMC twice injection on day 0 and day 7. Assessment of DES included changes in tear production (Schirmer's test), fluorescein staining pattern, conjunctival impression cytology, and corneal histological examination.

RESULTS:

After MMC injection, no obvious changes in the rabbit's eyes were noted by slit-lamp examination. Both the MMC 0.25 and the MMC 0.5 groups revealed decreased tear secretion after injection, and the MMC 0.25 group showed a continuous decrease in tear secretion up to 14 days. Fluorescent staining showed punctate keratopathy in both MMC-treated groups. In addition, both MMC-treated groups demonstrated decreased numbers of conjunctival goblet cells after injection.

CONCLUSION:

This model induced decreased tear production, punctate keratopathy, and decreased numbers of goblet cells, which are consistent with the current understanding of DES. Therefore, injecting MMC (0.25 mg/mL) into the LGs is an easy and reliable method to establish a rabbit DES model which can apply in new drug screening.

Authors: Chen Ching-An , Tung Hsiao-Fan , Liu Yu-Ling , Lin Chang-Ping
Published: May 2022

We report a case of Schnyder corneal dystrophy (SCD) treated with deep phototherapeutic keratectomy (PTK). A 33-year-old man presented with a 5-year history of blurred vision and corneal haze in both eyes. Slit-lamp examination revealed needle-like subepithelial crystalline depositions and prominent arcus lipoides bilaterally. Similar clinical findings were observed in the patient’s father. A diagnosis of SCD was made on the basis of the clinical presentation. PTK was performed using a multizone, multipass, and shoot and check technique with the WaveLight EX500 excimer laser. After 22 months of follow-up, the best-corrected visual acuity had increased from 0.5 to 0.9 in the right eye and from 0.3 to 0.9 in the left eye. SCD is rare but has a unique ocular presentation, which facilitates the diagnosis. PTK can increase patients’ visual acuity and eliminate the need for aggressive management through penetrating keratoplasty or deep anterior lamellar keratoplasty.

Published: May 2022

Nowadays, the removal of toxic heavy metals from industrial wastewater is a long standing problem due to the industrial progress worldwide. This study mainly focused on the production of a novel nMgO-bentonite nanocomposite using sol–gel method to enhance Cd ions removal from industrial wastewater. The nMgO-bentonite nano-composite was characterized for structural morphology and presence of functional groups using SEM/EDS, XRD and FTIR analysis. Cadmium sorption equilibrium and kinetic data were well fitted to Langmuir and power function models respectively as confirmed by the highest R2 (0.965), and the lowest SE (38*10-6) values among other studied models. The Langmuir removal capacity of the nanocomposite is 200 mg/g which is 60 times greater than that of bentonite. Increased Cd sorption on nano-composite with increased temperature from 287 to 307K and the thermodynamic results revealed that Cd adsorption process was endothermic and spontaneous. The data also showed highly repetitive application of nano-composite during six cycles of adsorption/ desorption experiment. The final results pointed out that nMgO-bentonite nano-composite has great adsorption affinity for Cd and could potentially employ as a cost-effective, ecofriendly and efficient sorbent for Cd removal from contaminated wastewater.

Published: May 2022

Skim is a major by-product of the virgin coconut oil (VCO) industry consisting of nutrients and is currently discharged to the environment as waste. Hence, this research aimed to utilize skim as a medium for Botryococcus braunii and Chlorella vulgaris growth. The effect of organic carbon resourced from glucose and glycerol on biomass was also investigated at certain concentrations with intervals 100:0 to 0:100 (%). Results indicated that Botryococcus braunii and Chlorella vulgaris cultivated under 20% VCO mill effluent gave the highest biomass production, which accounts for 1.69 g/L and 5.34 g/L; 89.40% and 86.70% COD reduction efficiency. Whereas, mixotrophic condition showed a positive trend for Botryococcus braunii at 80:20 (glucose:glycerol) with 5.60 g/L biomass production and 97.64% COD removal efficiency. Vice versa, the addition of glucose:glycerol gave an inhibitory impact on Chlorella vulgaris as the biomass production was merely 1.66 g/L with COD efficiency 94.03%.

Por primera vez se cita la existencia de dimorfismo sexual en el colémbolo Willowsia jacobsoni (Börner). Esta es la cuarta especie de la familia Entomobryidae que presenta un dimorfismo sexual evidente. Los machos con coloración típica se diferencian de hembras típicas de su misma edad por la ausencia de pigmento en el mesotórax , menos pigmento en el cuarto segmento abdominal y por su menor tamaño. Estas diferencias, que permiten distinguir ambos sexos mucho antes de la etapa adulta, se aplican a más del 80% de los adultos; un porcentaje bajo presenta variaciones que se discuten brevemente. La especie es redescrita a base de ejemplares puertorriqueños que representan la primera cita del género Willowsia para la Región Neotropical. Se incluye y se comenta brevemente toda la literatura sobre esta especie. Se discute el status de las seis variedades de W. jacobsoni, las que se consideran como meras formas, aunque se indican algunos casos que pueden representar especies diferentes. La seda cefálica S6 puede ser una macro- o microseda o puede ser una macroseda en un lado de la cabeza y una microseda en el otro lado.
¿CÓMO LLEGAMOS HASTA AQUÍ? ORDEN SOCIAL Y CAMBIO SOCIOCULTURAL
Authors:   Universidad de Buenos Aires – Instituto Superior de Viajantes, Ciudad Autónoma de Buenos Aires, Argentina, o Dallera Osvaldo
Published: May 2022

En este artículo abordamos el problema de la relación entre orden social y cambio sociocultural. En el acercamiento a esta inquietud cobran especial relevancia los principales factores que hicieron posible las transformaciones operadas en los últimos cien años. En ese tránsito se instala el modernismo como plataforma de lanzamiento de los cambios culturales, se consolida el igualitarismo en los vínculos sociales, como reverso de las relaciones verticales rígidamente estratificadas que regularon los intercambios comunicativos en el período precedente, y esos dos factores contribuyen a darle forma al democratismo como desvío y distorsión de las expectativas democráticas que habían despertado luego de la caída de los experimentos totalitarios de la primera mitad del siglo XX. Al día de hoy, y al final de estos cambios socioculturales, estamos en presencia de los efectos psicosociales derivados: primero, el intento de los sectores medios de poner en practica la buena voluntad cultural como mecanismo de ascenso social, y luego, ante el fracaso de esa tentativa, el advenimiento de una nueva masa de excluidos que están agrupados bajo la denominación de perdedores e insatisfechos de la modernidad. Esta nueva configuración de sujetos sociales canaliza su decepción como resentimiento e incorporan a su sociabilidad (trato, presencia y expresión ante los demás) en los sistemas de interacción las nuevas formas de agresividad contemporánea y vulgaridad moderna que se fueron gestando desde aquel punto de partida que nos hizo preguntar ¿cómo llegamos hasta aquí?, y que nos permiten decir “hasta aquí hemos llegado”.
Self-Definition and Change, The Role of the Cult of the Holy King and Statehood in the Global Space
Authors:   Institute for Hungarian Studies, Budapest, Hungary, Fabó Edit
Published: May 2022

The onset of globalization is rooted mainly in the imperial aspirations that define European culture. The former Hungarian kingdom in the middle of Europe was a dominant power in Central and Eastern Europe until the period of colonization. After that, its strength and greatness were heavily battered by the changes of history. The example of the founder of the state, St. Stephen, played an important role in the survival during the ordeals. His cult was made a national holiday by Maria Theresa in 1771, and after the Compromise of 1867, his memory was important even during the formation of today’s modern – multiethnic – Hungarian state. Then, following the Trianon decision, his spirituality flourished between the two world wars, and his legacy has been cherished more and more vigorously since the regime change. Hungary does not shy away from the challenges of globalization either, but the way of accession is influenced by the leadership’s vision of the future derived from the past. The task is formulated in a self-definition adapted to the situation of change. Hungarian research on the history of memory is a case study of how the values of local communities and localities fit into globality.

O conceito filosófico-científico do Cosmos como estrutura narrativa do conto fantástico "La Biblioteca de Babel"
Authors: Lafuente Luis Antonio Mopi
Published: May 2022

As narrativas fantásticas do escritor argentino Jorge Luis Borges foram influenciadas pela leitura erudita da literatura clássica, daí que nas suas narrativas se possa detectar a presença de conceitos filosóficos usados como estruturas. O conto "La Biblioteca de Babel" é um exemplo deste tipo de procedimento, no qual o conceito filosófico-científico da Ordem do mundo, proposto pelos filósofos pré-socráticos com o nome de κόσμος (Cosmos na forma transliterada, Universo na tradição latina), não apenas funciona como estrutura do espaço ficcional da Biblioteca de Babel e proporciona o conteúdo e a forma do enredo, mas também é questionado e atacado mediante uma teoria que tem todas as aparências de um procedimento lógico correto e válido, a qual postula que a Ordem do mundo que nos rodeia é formada pela repetição cíclica da mesma Desordem. Esta teoria é um ataque fantástico ao cientificismo europeu que excluiu o sobrenatural e o irracional do mundo real, relegando-os ao campo das meras superstições e crenças populares, manifestação moderna do embate entre a razão científica e a antiquíssima razão mítica.

The Profile Matching method is a solution to help determine the best Wheat Flour Brand according. The Profile Matching process, broadly speaking, is a process of comparing individual competencies into job competencies so that differences in competencies are known (also called gaps). The smaller the resulting gap, the greater the value weight, which means it has a greater chance of occupying that position. Because the many types of Wheat Flour Brands make it possible to choose the type, nature, and quality of the Wheat Flour Brand as desired and also in accordance with purchasing power. By recognizing the physical characteristics of a high-quality Wheat Flour Brand, we can actually distinguish a good Wheat Flour Brand from its ordinary quality, namely from the shape of the texture, color, and protein. A good brand of Wheat Flour usually has a high protein content. In addition, we can judge the quality of the Wheat Flour Brand from the presentation, whether it is clean or not.

Stock is one type of long-term investment that is quite in demand by the public because this investment brings quite a large profit for its investors. However, in relation to this, stock price movements, in general, tend to be non-linear and non-stationary, this is because stock prices can be influenced by several factors whose results can change the pattern of stock price values either up or down, so this can make it difficult to stock prices prediction. In this study, a comparative analysis of prediction models was carried out in predicting stock prices using a technical approach based on past data, while the data used were historical stock prices by taking data samples from three issuers from the Indonesian capital market. There are three methods that were tested in this study, including Linear Regression (LR), Random Forest Regression (RFR), and Multilayer Perceptron (MLP). The test was carried out with two data modeling, namely partitioning which was validated with Cross-Validation, and data modeling with Cross-Validation without partitioning. In this study, the prediction model with LR is able to produce a fairly low error prediction value with the lowest RMSE score of 0.010 and the highest RMSE of 0.012, the lowest MAPE of 1.2%, and the highest of 1.9%, the lowest MAE of 0.006 and the highest. of 0.009, and the highest R2 value was 99.8% and the lowest was 99.6%. It can be concluded that in this study, the Linear Regression prediction model is able to predict historical data on stock prices better than the RFR and MLP models.

Citrus nutrition: An Indian perspective
Authors: SRIVASTAVA A.K.
Published: May 2022

Diagnosis and management of nutrient constraints are the two important pillars of sound citrus fertilizer program, although its history in India is as old as cultivation of citrus. Of the different diagnostic tools (leaf nutrient standards, soil thresholds of soil available nutrients, metalloenzyme activity, inflorescence analysis, juice nutrient standards, xylem sap analysis); leaf and soil-based nutrient standards have established their superiority over rest of the diagnostic methods. Optimum leaf nutrients standards developed for different commercial cultivars in Indiahave further warranted the necessity of identifying nutrient constraints through cultivar specific diagnostics in order to inflict precision diagnosis. Similar observations were envisaged through optimum soil fertility limits suggested for Indian citrus cultivars, primarily governed by prevailing soil fertility constraints. Multi-location nutrient specific field response studies lacked heavily on the point of uniformity in yield and quality improvements when replicated at other locations. Site-specific nutrient management studies demonstrated soil type-based fertilization, suggesting the fertilizers to be tailored as per canopy size within an orchard to derive rationality in fertilizer use within an orchard. Fertigation has further reduced the optimum fertilizer requirement by 30-40%, in addition to microbial consortium-based integrated nutrient management saving 30% cut from conventional RDF. Many other significant advances have taken place to improve the fertilizer-use-efficiency e.g. sensor-based variable rate application, fertigation using magnetized irrigation, open field hydroponics and dual purpose microbially loaded substrate (organic manure) enriched with limited inorganic fertilizers collectively known as INM a plausible alternative.

The field experiment was conducted during 2017-18 and 2018-19 at Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) to study the effect of fertilizer and soil amendment on soil fertility and yield groundnut (Arachis hypogaea L.). The experiment was laid out in randomized block design with three replications and nine treatments. The pooled data revealed that the application of gypsum and phosphogypsum did not influence significantly the soil pH, EC, organic carbon and calcium carbonate content. However, the fertility status of soil in terms of available nitrogen, phosphorus, potassium and sulfur as well as exchangeable calcium, magnesium was found significantly higher with the application of RDF-sulfur free + 400 kg phosphogypsum ha-1. The available nitrogen, phosphorus, potassium, sulfur, exchangeable calcium and magnesium contents were increased by 10, 23, 7, 122, 42, and 14% with RDF-sulphur free + 400 kg phosphogypsum ha-1 as compared to control, respectively. Significantly higher pod (2.0 t ha-1) and haulm yield (2.5 t ha-1) of groundnut was observed with RDF-sulphur free + 400 kg phosphogypsum ha-1. Similarly, the oil and protein contents were also increased with phosphogypsum level and maximum oil (51%) and protein (29.4%) contents were observed with RDF-sulphur free + 400 kg phosphogypsum ha-1 treatment. This treatment was statistically at par in terms of soil fertility, yield, oil and protein content of groundnut with RDF-sulphur free + 300 kg phosphogypsum ha-1.

Secondary soil salinization is a major issue for sustaining food grain production in arid and semi-arid region due to the use of poor quality saline water, whichneeds amelioration before to be used for crop irrigation.In this regard, totally 12 saline bacterial isolates from saline water ecosystem, of which three best isolates, namely C8, C10 and C12, identified and used for amelioration of saline water whose electrical conductivity value (EC) ranged between 0.5 and 8.0 dS m-1 over the incubation period of two, five and seven days under laboratory conditions during 2017-20. The C10 and C12 bacterial isolates were highly efficient recording more than 30 % EC value decline but microbial efficiency decreased with increased salt concentration. The five days incubation optimized with 20 % reduction of EC value. However, the biological amelioration of water salinity was highly specific that five days incubation with C12 culture recording amelioration nearly 64 % decline of EC value only in low saline water. In contrast, all the cultures were equally effective on every saline water studied lowering more than 38% in 2.0 dS m-1 saline water, more than 22 % in 4.0 dS m-1 saline water, more than 16 % in 6.0 dS m-1 saline water, and more than 12 % in 8.0 dS m-1saline water for two days incubation period. On the whole, the microbial techniques based saline water amelioration abated 30% reduction of EC value associated with declining of ionic concentrations, such as Ca2+ by 40 %, Mg2+ by 31 %, Na+ by 24 %, SO42- by 18.4 % and Cl- by 10.5 %. The reduced salt build-up and increased crop performance would be the implication and characterization of the isolates is suggested further studies.

Field experiments were conducted at Bhubaneswar, Odisha during kharif seasons of 2018 and 2019 to study the growth behavior of rice varieties under nutrient management practices. Six treatment combinations comprising of three nutrient management (100% Soil Test Based Nitrogen Recommendation (STBNR), 75% STBNR + in situ green manuring (dhaincha) and 50% STBNR + in situ green manuring of dhaincha) and two rice varieties (Manaswinee of 125d duration and Hasanta of 145d duration) were tried in randomized complete block design (RCBD) with four replications. The results showed that crop growth rate (CGR) was significantly influenced by both nutrient management practices and varieties. Pooled over the years, application of 75% STBNR + green manuring of dhaincha exhibited the maximum CGR of 11.33 and 20.80 g/m2/day during 30-60 and 60-90 DAT, respectively and which were superior to 100% STBNR and 50% STBNR + green manuring of dhaincha. Similarly, rice cv. ‘Hasanta’ recorded CGR of 10.98 and 20.42 g/m2/day during 30-60 and 60-90 DAT, respectively, which were higher over cv. ‘Manaswinee’. The maximum relative growth rate (RGR) of 23.77 mg/g/day was registered with 50% STBNR + green manuring of dhaincha, being at par with 75% STBNR + green manuring of dhaincha during 60-90 DAT. Application of 75% STBNR + green manuring of dhaincha recorded the maximum Net assimilation rate (NAR) of 3.41 and 4.26 g/m2 leaf area/day during 30-60 and 60-90 DAT, respectively. Both cultivars were equally effective for RGR and NAR. The treatment trend for physiological indices led to higher grain yield under 75% STBNR + green manuring of dhaincha among nutrient management practices and cv. ‘Hasanta’ between rice varieties. Grain yield and the three physiological indices were positively correlated, but the correlation coefficient values were significant for CGR and NAR.

This study was conducted at Engineering farm, Navsari Agricultural University, Navsari, India, during winter 2016-17 using sorghum crop (Sorghum bicolar) to examine the effect of three land leveling (control or unleveled, conventional land leveling and leveling with laser guided land leveler) and three planting systems (ridge and furrow, double row bed planting and triple row bed planting). The laser guided land leveler significantly improved the growth attributes of sorghum as compared to the control whereas the growth attributes were recorded highest under double row bed planting. The highest yield attributes were recorded in laser guided land leveler. The best results of sorghum yield attributes were recorded under double row bed planting. In land leveling, laser guided land leveler significantly improved yield of sorghum (grain and fodder) as compared to control. Whereas, maximum sorghum yield was obtained under double row bed planting over rest planting system. The soil moisture distribution, water saving and water use efficiency were improved under laser guided land leveler with double row bed planting over rest of the treatments. The highest gross return, net return and benefit: cost ratio were obtained under laser guided land leveler with double row bed planting over rest of the treatments.

Biến dạng cưỡng bức do chênh lệch nhiệt độ là một trong những nguyên nhân thường gây ra nứt cho kết cấu bê tông của công trình cầu. Bài báo trình bày một số kết quả quan trắc thực địa sự biến thiên nhiệt độ trong bê tông của một số dầm cầu dạng hộp kín bằng bê tông cốt thép trong giai đoạn khai thác ở Việt Nam. Dựa trên các kết quả quan trắc này, một số tính toán mô phỏng tác động của sự biến thiên nhiệt độ lên dầm cầu cũng đã được thực hiện. Mặc dù các kết quả này mới là bước đầu do thời gian quan trắc chưa dài nhưng chúng cũng đã phản ánh được một số tác động của nhiệt độ lên công trình cầu mà tiêu chuẩn thiết kế chưa xét đến. Cụ thể là, trong các cầu dầm hộp, gradient nhiệt dương xuất hiện cả theo phương đứng và phương ngang. Gradient nhiệt âm cũng xuất hiện trên tất cả các mặt của cầu. Trên bản nắp và thành cầu, ứng suất do gradient nhiệt có thể lớn hơn ứng suất do hoạt tải gây ra và có thể gây nứt bê tông dầm cầu.

Các nghiên cứu về bê tông geopolymer sử dụng cát biển trên thế giới mới được phát triển khoảng 10 năm trở lại đây. Ở nước ta, các nghiên cứu về bê tông geopolymer sử dụng cát mặn và nước biển hiện còn khá sơ khai, chưa đánh giá hết tiềm năng của việc ứng dụng loại vật liệu này trong xây dựng hạ tầng ven biển. Nghiên cứu này sử dụng cát và nước mặn lấy từ vùng biển Cồn Vành, Thái Bình nhằm bước đầu đánh giá khả năng chế tạo bê tông geopolymer chịu lực từ các nguồn vật liệu nhiễm mặn không qua xử lý. Mười hai cấp phối geopolymer sử dụng cát biển, nước biển hoặc cát sông và nước ngọt đã được chế tạo. Cường độ chịu kéo khi uốn và cường độ chịu nén của các mẫu kích thước 40x40x160 cm tuổi 3, 7 và 28 ngày đã được xác định theo TCVN 3121-2003. Kết quả nghiên cứu cho thấy thời gian bảo dưỡng của bê tông geopolymer có thể rút ngắn hơn so với bê tông xi măng thông thường, tạo điều kiện để rút ngắn tiến độ xây dựng công trình. Cấp phối geopolymer sử dụng cát biển đạt cường độ tốt, tương tự như các mẫu sử dụng cát sông và nước ngọt. Như vậy có thể thay thế một phần cát vàng trong việc chế tạo bê tông chịu lực bằng cát biển, góp phần sử dụng hiệu quả nguồn cát phong phú và giảm khai thác lượng cát vàng đang ngày càng cạn kiệt.
