Elektrokoagulasi merupakan salah satu metode elektrokimia untuk mengolah polutan air dan limbah. Pada penelitian ini, proses elektrokoagulasi menggunakan elektroda aluminium diaplikasikan pada limbah artistik yang mengandung karbofuran untuk melihat nilai chemical oxygen demand (COD). Proses elektrokoagulasi dipilih dalam penelitian ini berdasarkan beberapa keunggulan, seperti mudah dan sederhana untuk diaplikasikan. Beberapa parameter seperti waktu elektrolisis, konsentrasi elektrolit, dan pengaruh pH telah diteliti pengaruhnya terhadap proses elektrokoagulasi. Hasil penelitian menunjukkan bahwa proporsi penurunan chemical oxygen demand (COD) terbaik adalah 64,40%. Kondisi terbaik yang diperoleh adalah waktu elektrolisis 60 menit, konsentrasi elektrolit 0,15 M, dan pH 10. Hasil yang diperoleh juga menunjukkan bahwa penurunan chemical oxygen demand (COD) tergantung pada beberapa parameter tersebut. Hasil ini dikonfirmasi dengan karakterisasi menggunakan spektrofotometer UV-Vis dan spektroskopi FTIR. Hasil spektrum UV-Vis menunjukkan adanya penurunan intensitas pada panjang gelombang 275 nm. Analisis hasil spektrum FTIR antara sampel awal dengan hasil elektrokoagulasi menunjukkan adanya kesamaan puncak serapan namun dengan intensitas yang jauh lebih kecil hal ini menunjukkan bahwa polutan pada limbah telah terendapkan.Kata Kunci: Elektrokoagulasi, Karbofuran, Al/Graphite, COD
El estereotipo antijudío en la educación secundaria
Authors: Perednik Gustavo D. , Reich Micaela
Published: April 2023

Los estereotipos de grupo son representaciones sociales en forma de ideas o creencias, y en ellos pueden sustentarse los odios de grupo. Uno de estos odios es el antisemitismo o judeofobia que, aunque su presencia es verificable, es escasamente abordado. La razón de esta escasez puede relacionarse con la complejidad del fenómeno. En general, en todos los estereotipos ocurre que, en la medida en que sean cognitivos, constituyen un campo fértil para la educación. A fin de detectar los estereotipos de grupo, la adolescencia es una edad apropiada, porque el juicio moral ya está formado, y tratarlos podría contribuir a la educación en valores durante esta etapa evolutiva. Se administró un cuestionario de autoinforme a 321 estudiantes de entre 16 y 18 años, en cuatro ciudades de tres países sudamericanos. Asimismo, se realizaron entrevistas a especialistas. Los estudiantes consultados no habían tenido contacto directo con judíos al momento del estudio. El objetivo de la gestión del cuestionario, basada en las premisas del Test de Asociación Implícita, fue obtener palabras asociadas a la voz “judío”. Los resultados indican que casi la mitad de los términos asociados tenían una connotación negativa, vinculada con la noción del dominio. La inclusión en el currículo escolar de algunas explicaciones de este fenómeno podrá ayudar a atenuarlo.

Published: April 2023

Mexican Americans living in the Rio Grande Valley (RGV) have a high prevalence of type 2 diabetes (T2D). The US–Mexico border frontier has a unique blended culture of American lifestyle and Mexican traditions. Some examples of the cultural traditions are the food and the use of herbal medicine, but these traditions are in danger of disappearing after a very short number of generations living in the United States. This article describes the use of animal models under experimental conditions to solve practical questions (etiology or treatment). We performed studies with murine (ie, mouse and rat) models to elucidate the characteristics of medicinal plants that modulate glucose metabolism and inflammation and protect from bone loss, complications related to T2D. The University of Texas Rio Grande Valley researchers also have collaborated with the University of Texas Health Science Center at San Antonio researchers in performing studies in nonhuman primates (NHP) (ie, baboon) to understand the effect of T2D and diets on organs and tissues. With the new knowledge gained from the use of animal models (murine and NHP), new therapies are discovered for the prevention and treatment of T2D and its related complications, such as bone loss and nonalcoholic fatty liver disease, all of which the Mexican American and other human populations are at high risk of developing.

Authors: Makai Attila Lajos
Published: April 2023

Az ökoszisztéma fogalma a gazdasági, a tudományos és a szakpolitikai rendszerekben egyaránt egyre népszerűbbé válik, használata beépült a mindennapi gyakorlatba. A fogalom egyszerre biztosít elméleti keretet a szakpolitikai tervezési dokumentumoknak, az üzleti terveknek, valamint a tudományos kutatásoknak. Ezt elősegíti az a holisztikus megközelítés is, amely az ökoszisztémákat már nem csupán erőforrás-allokációs rendszerekként, hanem a kormányzást, a kognitív elemeket és az interakciókat is magában foglaló komplex struktúraként értelmezi. A népszerűség növekedésével párhuzamosan az egyes ökoszisztémák teljesítményének mérésére és összehasonlítására indexeket és rangsorokat dolgoztak ki, amelyek nem csak a kapcsolódó diskurzust, de az ökoszisztéma szereplőinek döntéseit is befolyásolják. Az innovációs és a vállalkozói ökoszisztéma keretrendszereihez képest a startup-ökoszisztéma fogalma viszonylag új kategóriának számít. Ehhez kapcsolódnak az elmúlt években megjelenő rangsorok, amelyek a startup-ökoszisztémák teljesítményének összehasonlíthatóságát hivatottak biztosítani. Ezek a rangsorok és az alapjukat képező változók eddig nem álltak a tudományos érdeklődés középpontjában, de az ökoszisztéma fogalmi keretrendszerének holisztikussá válása szükségessé teszi a terület mélyebb megértését és elemzését. Ehhez első lépésben az adekvát kutatási kérdések és a jövőbeni kutatási irányok strukturált összefoglalására van szükség. Jelen tanulmány erre vállalkozik, bemutatva a holisztikus ökoszisztéma-szemlélet sajátosságait, valamint az ebből eredő és a kérdéses rangsorokat érintő lehetséges kutatási agendát.

Background: Sleep apnea is usually associated with negative outcomes and underdiagnoses. STOP-Bang Questionnaire is a screening method for obstructive sleep apnea (OSA) that is recognized for the diagnosis of OSA in surgical and medical patients. This cross-sectional study aimed to evaluate the ability of the STOP-Bang test to predict complications after supratentorial craniotomy.
Methods: In a cross-sectional study, 200 patients who were candidates for supratentorial craniotomy surgery who were referred to Loghman Hospital from July 2019 to September 2020 were included in the study. The STOP-Bang questionnaire was completed the day before the operation or during the visit to the anesthesia clinic. Demographic characteristics, body mass index (BMI), neck and waist size, underlying disease, and airway examination were performed to assess the Mallampati score for patients. According to the STOP-Bang scoring system, patients were categorized into two groups: low risk (score less than 3) and high risk (score higher or equal to 3). Data were analyzed using SPSS software version 20.
Results: A total of 125 patients (62.5%) were low risk and 75 patients (37.5%) were high-risk. There was no statistically significant difference between the two groups of patients in terms of gender (P = 0.108). BMI over 35 kg / m2 and age over 50 years were higher in the high-risk group. The incidence of Malampati III or IV was higher in the high-risk group (29.3 vs. 6.4%). Smoking was higher in the high-risk group (29.3 vs. 16.8%). The frequency of airway obstruction, re-intubation, hypoxia, and length of hospitalization in recovery, and in the intensive care unit was significantly higher in the high-risk group. The level of the ROC curve for airway obstruction required intervention equal to 70.2% (95% confidence interval: 79.6-6.7). STOP-Bang showed good predictive power (Diagnostic power> 50percentage) for the need for nasal or oral airway implantation, re-intubation, hypoxia and hypotension of arterial blood, and difficulty in breathing or speaking. A score higher than two showed the predictive power of all evaluated outcomes.
Conclusion: Our findings showed that the occurrence of premature respiratory complications after supratentorial craniotomy surgery is more common in patients with a screening score of three or higher on the STOP-Bang test, and this test can detect adverse complications after surgery.

Published: April 2023

Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility. Herein, we aimed to screen GDF9 of mature follicles in women with differentPCOS phenotypesundergoing controlled ovarian hyperstimulation (COS) and analyse the correlation between GDF9 expression levels and the oocyte developmental ability. In this study, we compared the level of GDF9 in follicular fluid (FF) and cumulus cells(CCs) of mature follicles collecting from different PCOS phenotypes. The indenpendent effect of GDF9 on blastocyst formation and clinical pregnancy was determined by Binary Logistic Regression analysis. The GDF9 levels in FF for phenotype A and B were significantly increased, compared to the phenotype D, (P=0.019, P=0.0015, respectively). Increased GDF9 expression in CCs of phenotype A and B was accompanied by the changes of FF. The analysis of the multivariable logistic regression showed that GDF9 was a significant independent prognosticator of blastocyst formation(P＜0.001). The phenotype A had a higher percent of blastocyst formation than the phenotype B and D (P＜0.001). Taken together, GDF9 expression varied in different PCOS phenotypes. The phenotype A had a higher GDF9 level and even more ability of blastocyst formation.
Research on interactive system of Chinese-English translation model in cloud computing environment based on deep learning
Authors: Mai Yinghong , Yuan Xin
Published: April 2023

At present, human translation is characterized by low efficiency, high cost, high consumption of resources and time, so it is urgent to study automatic translation technology to meet the needs of information interaction and language communication in various countries under the background of economic globalization. This topic has also become a hot issue in the field of translation. After a long period of development, machine translation technology has gradually become popular and widely used, replacing human translation technology as the mainstream technology. Therefore, this paper implements the construction of an interactive system of English Chinese bilingual translation model based on cloud computing environment by introducing deep learning algorithm. The system can learn by itself on the basis of analyzing source documents, and predict target translation output by extracting features. The system is equipped with a translation engine based on the data source, which can realize interactive translation, and the final output can be achieved by processing the predicted translation output and based on the translator's understanding. Through the design of simulation experiments for system detection, the results show that the Chinese English translation model system has a high translation quality. By comparing it with the baseline system, it can be seen that both of them can translate sentences normally in 8 PR cycles (PR * 8, about 18% KSMR), and the data set improvement rate is about + 35 BLEU, that is, 76 BLEU is finally achieved. This proves that users can maintain the translation accuracy while reducing the number of effective interactions by using the optimized translation model to translate the target text, showing the effectiveness. In this paper, an interactive Chinese English translation system is designed by combining deep learning with cloud computing.

Published: April 2023

Background:As the number of studies investigating idiopathic pulmonary fibrosis (IPF) and lung adenocarcinoma (LUAD) continues to grow, increasing evidence supports a strong correlation between these two diseases. However, the underlying common pathophysiological mechanisms remain unclear.Objective：The objective of this study is to further elucidate potential key genes and pathological mechanisms associated with IPF and LUAD.Methods:We searched and downloaded the gene expression datasets for IPF patients and their corresponding normal tissue (GSE53845), as well as the datasets for LUAD patients and normal tissue (GSE176348) from the Gene Expression Omnibus (GEO) database. Using these datasets, we identified differentially expressed genes (DEGs) and common genes, which were subjected to gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. To further elucidate the underlying mechanisms of IPF and LUAD, we constructed a protein-protein interaction (PPI) network and identified transcription factors (TFs) that may regulate key genes.Results:Ninety-three common genes were identified in both the IPF and LUAD datasets with a significance level of P<0.05. Enrichment analysis revealed 936 GO terms and 13 KEGG pathways. Using cytoHubba and van plots, we selected the top thirteen key genes, including COL1A1, COL3A1, TIMP3, IGF1, CTHRC1, SULF1, MMP12, WNT3A, CCL5, GREM1, CCL19, HPGD, and AKR1C3, and further analysis of these genes was performed. GO analysis revealed significant enrichment in the regulation of animal organ morphogenesis, extracellular matrix organization, and extracellular structural organization. The KEGG pathway enrichment analysis showed that proteoglycans were significantly enriched in cancer, ovarian steroidogenesis, and arachidonic acid metabolism. Furthermore, we identified six TFs that may regulate the expression of these key genes.Conclusions:Our findings suggest that specific key genes and shared mechanisms play a role in the development and progression of both IPF and LUAD. These key genes and mechanisms may represent potential targets for therapeutic intervention and provide novel insights into the underlying pathophysiology of these diseases.
Electrodynamics-based Quantum Gate Optimization with Born Scattering
Authors: Gautam Kumar
Published: April 2023

In this paper, we propose employing electron scattering to realize unitary quantum gates that are controlled by three qubits. Using Feynman’s rules, we find an expression for the transition amplitude for scattering from an external electromagnetic source. In this context, the scattering amplitude is modeled as a unitary gate whose state can be regulated. The optimal value of the vector potential needed to implement the gate is obtained by minimizing the difference between the designed gate and the target gate, with the total energy consumed as a constraint. The design algorithm is obtained by discretizing the resulting integral equations into vector equations. This design algorithm can be applied in various fields such as quantum computing, communication, and sensing. It offers a promising approach for developing efficient and accurate gates for quantum information processing. Furthermore, this approach can also be extended to design gates for multi-qubit systems, which are essential for large-scale quantum computing. The use of this algorithm can significantly contribute to the development of practical quantum technologies.

Published: April 2023

INTRODUCTION
Activated coagulation time (ACT) measurement is performed to monitor the level of anticoagulation provided by heparin during cardiopulmonary bypass, coronary angioplasty and dialysis. In this study, the newly developed device and the consumable ACT tubes of this device were compared with the current methods used in hospitals and its usability as a reliable product was evaluated.
METHOD
This study was carried out in the cardiovascular surgery operating room of Gazi University Medical Faculty Hospital after the approval of the ethics committee and the approval of the Turkish Medicines and Medical Devices Agency . A total of 100 patients over the age of 18 who received heparin during cardiac surgery were included in the study. In our routine practice, Hemochron device with cuvettes (Hemochron Signature, Spain) constituted the “Hemochron cuvette” group and Hemochron device with tubes (Hemochron Response, Spain) constituted the “Hemochron tube” group. Hemonart device and tubes (CompactOne 9 and BlacT-ACT tube) constituted the “Hemonart tube” group. Measurements made with the above 3 devices simultaneously; the baseline value before heparinization was repeated at 5th minute after heparinization, after the initiation of cardiopulmonary bypass, and 5 minutes after protamine administration. The correlation of the measurements obtained with the 3 devices was evaluated.
RESULTS
When basal ACT measurements were evaluated; The mean ACT of Hemonart tube was measured as 148.54±26.54 sec and Hemochron tube (122.67±16.38) and Hemochron cuvette (117.94±15.06) values were statistically significantly higher (p<0.0001, p<0.0001, respectively). When measurements after heparin and during cardiopulmonary bypass were evaluated; Hemonart tube and Hemochron tube mean ACT values were similar in both groups (p=0.356) but statistically higher than Hemochron cuvette values (p<0.0001, p=0.003, respectively). Mean ACT values of Hemonart tube following protamine administration were statistically significantly higher than Hemochron tube and Hemochron cuvette values (p<0.0001, p<0.0001, respectively). A positive correlation was found between the values measured with different devices at all measurement time points. The strongest correlation was found between Hemonart tube and Hemochron tube values at baseline, post-heparin, during cardiopulmonary bypass and following protamin administration (r=0.546, p<0.0001; r=0.512, p<0.0001; r=0.533, p<0.0001, r= 0.407, p=0.001, respectively).
CONCLUSION
It has been concluded that Hemonart brand devices and tubes can be used safely.

Однією з важливих проблем сьогодення була пандемія Covid-19, яка сколихнула життя людей, зокрема вплинула і на навчання сту-дентів. У результаті чого студентів вишів з початком пандемії перевели на дистанційне навчання. Актуальною для нас стала проблема вивчення психо-емоційного стану студентів в умовах дистанційного навчання, соматичних і поведінкових проявів їхньої тривожності.

Метою статті є оцінити психоемоційний стан, соматичні та по- ведінкові прояви тривожності у студентів-медиків впродовж дистан- ційного навчання.

Методи дослідження. Опитано 76 студентів 2 курсу шляхом анонім- ного анкетування. Для обстеження було використано онлайн-анкету на базі Google Forms, яка включала запитання з метою вияв-лення психоемо- ційних та соматичних проявів тривожності. Для досяг-нення поставленої мети були поставлені наступні завдання: виявити емоційно-поведінкові реакції студентів та дослідити соматичні прояви тривожності за допо- могою розроблених опитувальників.

На основі аналізу результатів анкетування виявле-но, що всесвітня пандемія Covid-19 була значним соціальним фактором, який впливав на функціонування організму та поведінкові реакції сту-дентів, але більшість із них навчилися контролювати свої емоції та поведінку. Тільки 19,7% ре- спондентів повідомили про збільшення нега-тивних емоцій у повсякден- ному житті під час дистанційного навчан-ня, тоді як 40,8% повідомили про зниження інтересу до дистанційного навчання порівняно з навчанням

 

офлайн, відмічали часте відчуття тривоги та апатію. Впродовж дис- танційного навчання психоемоцій-ний стан погіршився у близько 25% респондентів.

Вивчивши прояви тривожності на соматичному рівні, ми вияви-ли, що більшість студентів не мали ознак соматичних проявів триво-жності, 63,2% студентів ніколи не відчували запаморочення чи головного болю впродовж дистанційного навчання, 75% студентів ніколи не відчували тремору. Фактично, 71,1% з них не відмічали підвищення ча-стоти серцевих скорочень або підвищеного артеріального тиску впро-довж дистанційного навчання, але більшість респондентів (56,6%) часто відчували втому або сонливість.

Наші дослідження показали, що світова пандемія мала негативний вплив на функціонування організму та поведінкові реакції студентів. Проте за період дистанційного навчання студенти вироби-ли стресостійкість і навчилися адекватно реагувати на соціальні виклики, які постають перед людством, починаючи з 2019 року.

Published: April 2023

Soil transmitted helminth infections (STHI) are prevalent among elementary school children in Indonesia. The nutritional impairments that an infection can cause have their consequences for the children’s development and health. This study aimed to determine children’s knowledge and behaviour in relation to the prevalence of STHI among elementary school children in Jepara, a rural regency in Indonesia. The study intended to evaluate the effectiveness of the current elimination program for STHI in this area. A cross-sectional study was conducted among 132 children from eight elementary schools in Mlonggo, Jepara. The research population consisted of children aged eight to ten years old. During September and October 2018, the research population was obtained by consecutive sampling. Information about the children’s knowledge and behaviour regarding STHI was collected using a questionnaire. Stool samples were collected to determine STHI prevalence. Analysis was done using chi-squared and Spearman’s rho tests. Out of 132 children examined, no children had STHI. Scores on STHI knowledge were most often low (51.5%), while scores on behaviour were mostly average (67.4%). Statistical analysis showed that residence was significantly associated with the level of knowledge about STHI (P = 0.007). Additionally, gender (P = 0.002) and a previous STHI (P = 0.041) were significantly associated with the children’s behaviour concerning STHI. This study revealed inadequate knowledge and behaviour concerning STHI in elementary school children in Mlonggo, Jepara. Even though the prevalence of STHI was 0% in the study population, a proper health education program to teach children about STHI is still necessary.

The solvents used in this study consisted of distillated water, methanol, and n-hexane solvent. The purpose of this study was to determine the secondary metabolites in Red Lemongrass (Cymbopogon nardus (L.) Rendl.) extract using different three solvents. Red Lemongrass extract was prepared by maceration method using distillated water, methanol, and n-hexane (10 gram: 100 mL) as solvents. Results of the extract were subjected to a phytochemical screening test consisting of flavonoids, alkaloids, saponins, tannins, and triterpenoids. The results of phytochemical screening showed that alkaloids, flavonoids, triterpenoids, and saponins were drawn attracted to the distillated water solvent. Meanwhile flavonoids and triterpenoids were drawn to methanol solvents. In addition, triterpenoids were drawn to n-hexane solvents. The best solvent on maceration results will be used as a reference for testing the ability of the extract as an antidiabetic agent.

Aim: This study was conducted to develop a population pharmacokinetic
(PK) model of methotrexate in Korean patients with hematologic
malignancy, identify factors affecting methotrexate PK, and propose
optimal dosage regimen for the Korean population. Methods: Data were
retrospectively collected from 188 patients with acute leukemia or
non-Hodgkin’s lymphoma who were admitted to Severance Hospital for the
period from 2005 to 2015. Using demographic factors and laboratory
results as potential covariates for PK parameters, model development was
performed using NONMEM and optimal dosing regimens were developed using
the final PK model. Results: A two-compartment model incorporating body
weight via allometry best described the data, yielding typical parameter
values of 25.99L for central volume of distribution (V_1), 18.76L for
peripheral volume of distribution (V_2), 12.9L/h for clearance (CL) and
0.646L/h for inter-compartmental clearance. Covariate analyses showed
that, at the weight of 50kg, CL decreased by 0.11 L/h for each one-year
increase in age above 14 years old and decreased to 0.8-fold when serum
creatinine level doubled, indicating the importance of age-specific dose
individualization in methotrexate treatment. Volume of distribution at
steady state derived from PK parameters (=V_1+V_2) was 0.90L/kg, which
was similar to those in the Western or Chinese population. Optimal doses
simulated from the final model successfully produced the PK measures

Methodological approaches to the formation of the pre-service Music teachers' systematic idea of the national musical culture
Authors: Shi Ma
Published: April 2023

The work is devoted to the formation of a systematic idea of the national musical culture (NMC) in the music teachers training process. The expediency and validity of four pedagogical approaches have been determined. It concerns systemic, culture-based, activity-centred and hermeneutic approaches. Based on the conceptual provisions of researchers' works, as well as the method of systemic genre modelling of musical culture, the idea of the structure of the NMC as a systemic and holistic phenomenon is accepted as a guideline. The basis of the NMC is the tradition of folk art, folklore of large and small peoples belonging to a single nation. Folklore is a complex phenomenon that should be presented and studied as a system of song, dance, and instrumental genres (mythological, ritual and magic, calendar and ritual, epic, game, etc.) The author describes that the genre model of the NMC used in the study allows to cover all the main characteristics and elements of the cultural practice of music, such as: the activities of performing musicians; functioning of theatres, concert organisations, creative unions; work of educational institutions; production and use of musical instruments, sheet music and books; media activity, etc. Therefore, the NMC can be considered not only in terms of its genre content. However, with any approach, from any point of view, the theoretical reflection of musical culture will be a multi-element, multi-faceted and multi-level unity. They are implemented through the application of a complex of pedagogical principles, methods and forms of education, such as: the principle of coordination and subordination of artistic cultures and their components; the principle of the "spiral trajectory" of the educational course thematic composition; the principle of the genre and style model of the NMC; the method of immersion in culture; the method of multi-artistic representation of educational material; the principle of establishing the level of cultures affinity, which regulates the involvement of comparative analysis methods; the principle of creative assimilation of the music-language system of the NMC; the didactic game method; the "hermeneutic circle" principle; the method of creating mnemonic symbols, etc.

Published: April 2023

El desarrollo y productividad de los cultivos agrícolas está directamente relacionado con el suministro nutricional que estos reciben. La hipótesis de esta investigación es que la concentración de iones medidos en la solución del suelo, permite evaluar la eficiencia del manejo nutricional y su efecto sobre el cultivo, así, la concentración de iones está condicionada por el aporte mineral y los procesos de intercambio iónico del suelo. El objetivo de ésta investigación, fue medir el efecto de la aplicación continua de cuatro concentraciones de solución nutritiva sobre la concentración de iones en la solución del suelo y la respuesta en el cultivo de tomate bajo invernadero. El ensayo se estableció en suelo calcáreo bajo un diseño de bloques completos al azar con tres repeticiones, con plantas de tomate indeterminado. Los tratamientos fueron cuatro concentraciones con diferente proporción de la solución Steiner modificada para el cultivo de tomate: 1) 50, 2) 75, 3) 100 y 4) 125%, que fueron aplicadas de forma continua por fertirriego. En cada tratamiento se extrajo la solución del suelo y se midió la concentración de los iones NO3-, K+ y Ca+2, el pH y la conductividad eléctrica durante 18 semanas. Al mismo tiempo, se midió la respuesta en el cultivo. La concentración de la solución nutritiva, aplicada de forma constante al cultivo de tomate, presenta una relación directa con la disponibilidad de nutrientes. La solución nutritiva al 125% generó mejor crecimiento, fisiología, calidad comercial y rendimiento agronómico. El calcio fue el único elemento que se detectó en niveles suficientes en la solución del suelo a partir de una concentración de 50% en la solución nutritiva, debido a su alta disponibilidad original del suelo.

Materials and Methods: Bauhinia variegata trees were monitored and monitored for seasons 2021-2022 in three locations in the city of Al-Bayda - eastern Libya, and flower abnormalities were documented photographically.

 Results: The results showed the registration of a new pattern of Bauhinia variegata after about 32 years of cultivation in of Al-Bayda city, libya with a clear increase in the number of petals (6-7-8 petals) superimposed (double) or contiguous, by up to 20% for each branch, with two petals often mottled, this mottled rarely disappears, the results also showed an increase in the number of stamens, and the emergence of some of them bilaterally incorporate with one of them turning into a petal.

Conclusion: The cause of this abnormality is believed to be the drop in temperature during the two study seasons.
Evidence of The Successful Conservation of Enhalus Acoroides in Terms of The Diversity of Bivalves on The Coast of East Lombok
Authors: Umami Rizal , Idrus Agil Al
Published: April 2023

The existence of seagrass in coastal areas can affect marine biota that live around it. Seagrass has an important role as an area of ​​care, spawning, and protection. This study aims to determine the success of conserving seagrass beds of the Enhalus acorodies species in terms of bivalve diversity on the south coast of East Lombok. The research was conducted using transect and observation methods. The data obtained were analyzed using evenness index, diversity index, and species richness. The results of the study found 10 types of Bivalves in Poton Bako. Bivalves diversity index is included in the medium category of 2,228. The evenness index of bivalves was 0.409 in the low category. Then, the species richness index is 1.653 in the low category. The species diversity of Bivalvia in seagrass beds in Poton Bako is still relatively moderate so that the sustainability of the seagrass species Enhalus acoroides can be said to be maintained. The existence of a feed source or substrate derived from the remains of seagrass is used as a source of feed. The conservation of Enhalus acoroides seagrass needs to be maintained so that it has an impact on the survival and diversity of Bivalves in the area.

Mules Island and its surroundings are included in the Savu Sea National Park (TNP) area and administratively included in the Manggarai Regency, East Nusa Tenggara Province (NTT). The waters of the area have a high potential for coral reef ecosystem resources and are important support for the marine life. However, the current condition of anthropogenic pressure continues to increase due to an increase in the number of people living on the coast and small islands. One of the pressures that are currently a big issue is the existence of marine debris, where studies related to its impact and distribution on coral reef ecosystems are still very few. The purpose of this study was to determine the distribution and types of marine debris in the coral reef ecosystem on Nucamolas Island and its surroundings. Observations were made on 1-3 November 2021 at 12 stations. The research method used is the belt transect method with an area of 500 m2. Data collection was assisted by SCUBA diving equipment at a depth of 5-7 m on the coral reef flat. The results of this study found that the dominant marine debris in the coral reef ecosystem was organic waste (64.3%) and a group of macro debris (71,4%). Based on the type, the dominant species found were logs (37%), which physically damaged the coral, especially when currents and waves were moving. The distribution of marine debris at the study site was only found at 8 stations while the other 4 were not found.
