Published: March 2024

Spodoptera frugiperda is an invasive pest that attacks maize throughout Indonesia. As an invasive pest, the population of S. frugiperda continues to increase exponentially, leading to outbreaks. Both internal factors (biology) and external factors (weather, host, and natural enemies) can affect the growth rate of pest populations. This research was conducted to assess the population dynamics of S. frugiperda based on the extent of its infestation and damage to maize post-invasion in Lampung Province. Observations were made in maize fields in 15 districts of Lampung Province from 2019 to 2022. Damage intensity was calculated based on the leaf damage scale. Weather data from 2019 to 2022 was obtained from the Lampung Province Central Statistics Agency. The research results indicate that upon the initial introduction of S. frugiperda to Lampung Province, the population increased exponentially, as observed based on the level of infestation and damage to maize. There was an outbreak from late 2019 to early 2020, and after that, there was a population decline. The population increase coincided with the early rainy season, which is associated with the beginning of the maize planting season. Although the level of damage to the maize is considered slight, S. frugiperda can cause anywhere between 21.94% to 51.38% of damage.

Provincializing Island Poetics: The Personal as the Spatial in N S Madhavan’s Litanies of Dutch Battery
Authors: Wadhwa Soni , Alias Jintu
Published: March 2024

Affect towards islands is a unique approach to engage with in discussions of the phenomenology of fictional islands. This affect complements the already identified tropes within island poetics: those of sensorial exploration, spatial practices, and textural detailing of islands. This article turns to a work of fiction about a fictional island based on the island city of Kochi in south India to unpack an alternative aesthetic of spatiality, the kind that changes the personal/political relationship to personal/spatial one. We argue that the novel, Litanies of Dutch Battery (the novel in question) by N.S. Madhavan, expands inquiries into phenomenology of fictional islands by making space for corporeal memory and collective memory in storytelling. These memory-oriented narrative devices, we suggest, “provincialize” island poetics to add a hermeneutic of postcolonial angst to the repertoire of formal features of literary islandness.

Published: March 2024

Phalaenopsis flowers possess extraordinary longevity. However, the changes of sugars, including glucose, fructose and sucrose, in organs of floret during different flowering stages of inflorescences attached to a plant have not been reported. To accomplish this, the sugars level in different floret organs were studied at 4 different stages (1. half open, 2. bloom 1 month, 3. bloom 2 months, and 4. wilting). Glucose and fructose were the major soluble sugars in the sepal, petal, labellum, pedicel, and remainder (including the column, anther cap, pollinia, and stigma) of a floret, but their levels decreased from stages 1 to 4. However, the amount of sucrose increased significantly at stage 4 in the sepal, petal, pedicel, and remainder, with the exception that the labellum remained constant throughout all stages. These results demonstrate that glucose and fructose are the major solutes that contribute to floret opening and blooming, and sucrose is salvaged and exported before floret senescence for opening other florets on the same inflorescence. Meanwhile, labellum possesses different sugar metabolism from other organs of Phalaenopsis floret.

Published: March 2024

Cut greens are emerging as an important constituent of the floricultural industry as they add freshness and colour to floral designs. An experiment was conducted to evaluate the effect of different coloured shade nets (black, blue, green, red, white and no shade) at 50% shade intensity on growth and quality parameters of Dianella tasmanica and Pleomele reflexa. Both species significantly responded to the change in colour of shade nets. In D. tasmanica, maximum plant height (85.66 cm), stem diameter (8.63 mm) and leaf length (68.33 cm) were recorded under red shade net, while, plant spread (63.03 cm) and leaf breadth (4.06 cm) under black shade net, however, leaf thickness (0.57 cm) and vase life (24.33 days) under white shade net. In P. reflexa, maximum plant height (63.66 cm), stem diameter (9.76 mm), leaf length (17.50 cm), leaf thickness (0.93 cm) and SPAD index (60.10) were recorded under red shade net, whereas, plant spread (36.34 cm) and leaf breadth (3.00 cm) under black shade net, and vase life (25.66 days) under white shade net. Thus, red coloured shade nets could be preferred commercially for better performance of D. tasmanica and P. reflexa.

Published: March 2024

Tomato cultivation is an important agricultural activity in northeast of Argentina, and disease control is indispensable for its production. The purpose of the current study was to identify two fungi isolated from tomato plants cultivated in greenhouses, with symptoms of leaf mould disease and a strain of the genus Cladosporium from a culture collection, and evaluate their in vitro susceptibility to four commercial fungicides. Macro and microscopic examination, molecular characterisation and sequence analysis were applied for identification. Broth dilution and spread plate methods were used to determine the minimal inhibitory concentration (MIC) and minimal fungicide concentration (MFC). The active ingredients of the products were azoxystrobin+difenoconazole, trifloxystrobin+tebuconazole, chlorothalonil and metalaxyl-M+mancozeb. The results were processed using the Kruskal-Wallis method. The isolates were identified as Cladosporium cladosporioidesa-c; consequently, lesions found on tomato plants did not corrspond to Cladosporium fulvum. There was a significant statistical difference between the obtained values. Qualitatively, the three strains had a similar behaviour for chlorothalonil (MIC values: 0.25 - 0.5 μg/ml, MFC values: 4 μg/ml). In all cases, tests with metalaxyl-M+mancozeb yielded higher values than those achieved for chlorothalonil (MIC values: 8 μg/ml, MFC values: 8- 32 μg/ml). trobilurin-formulated fungicides were less effective against C. cladosporioidesa-b (MIC values: 16-256 μg/ml, MFC values: >64 μg/ml). C. cladosporioidesc was the most sensitive isolate. The information about the presence of a non-frequent fungus and its fungicide susceptibility, would be useful for establishing control strategies and enhance production.

The Antigen-Processing Pathway via Major Histocompatibility Complex I as a New Perspective in the Diagnosis and Treatment of Endometriosis
Authors: Nowak Izabela , Bochen Patrycja
Published: March 2024

Endometriosis is a debilitating gynecological disease defined as the presence of endometrium-like epithelium and/or stroma outside the uterine cavity. The most commonly affected sites are the pelvic peritoneum, ovaries, uterosacral ligaments, and the rectovaginal septum. The aberrant tissue responds to hormonal stimulation, undergoing cyclical growth and shedding similar to appropriately located endometrial tissue in the uterus. Common symptoms of endometriosis are painful periods and ovulation, severe pelvic cramping, heavy bleeding, pain during sex, urination and bowel pain, bleeding, and pain between periods. Numerous theories have been proposed to explain the pathogenesis of endometriosis. Sampson’s theory of retrograde menstruation is considered to be the most accepted. This theory assumes that endometriosis occurs due to the retrograde flow of endometrial cells through the fallopian tubes during menstruation. However, it has been shown that this process takes place in 90% of women, while endometriosis is diagnosed in only 10% of them. This means that there must be a mechanism that blocks the immune system from removing endometrial cells and interferes with its function, leading to implantation of the ectopic endometrium and the formation of lesions. In this review, we consider the contribution of components of the Major Histocompatibility Complex (MHC)-I-mediated antigen-processing pathway, such as the ERAP, TAP, LMP, LNPEP, and tapasin, to the susceptibility, onset, and severity of endometriosis. These elements can induce significant changes in MHC-I-bound peptidomes that may influence the response of immune cells to ectopic endometrial cells.
Exploring the impact of weather patterns on exceptional flooding events in the Nekor watershed, NE Morocco
Authors: Mashoudi Ayoub Al , Akallouch Adil , Ziani Mouloud , Mousaoui Mhamed El
Published: March 2024

This study investigates the recurring floods within the Nekor Basin of NE Morocco, a phenomenon dating back to 1944. A multitude of factors has contributed to these recurrent floods, which profoundly affect the northern region encompassing the Nekor Plain. The research primarily investigates the influence of specific weather conditions on the surge of water levels in “Wadi Nekor” and the ensuing consequences when the valley veers from its primary course. The research findings strongly indicate that a significant portion of these flood events can be attributed to “Cut-Off Low” (COL) and atmospheric rivers (ARs), frequently aligning with mean sea level pressure (MSLP) systems located over, or in proximity to, the Moroccan region. This study employs a systematic classification and arrangement methodology for both upper and lower atmospheric levels in analyzing pertinent cases.
Religiosity and climate change: An eco-religious approach
Authors: Agusalim Lestari , Karim Muhamad
Published: March 2024

An eco-religious approach is one that combines religious beliefs with ecological awareness, thus giving rise to responsibility for the natural environment, such as the threat of a climate crisis due to climate change, as part of the understanding of religion itself. This approach is not universally accepted because views on climate change, and the role of humans in addressing it, can vary among different religions and religious traditions. This research explores the relationship between religiosity and climate change, with a focus on the concept of an eco-religious approach. The aim was to understand how religiosity can influence climate change using the ecological footprint as a proxy. The cross-country robust regression analysis method was employed to address this objective. Robustness and sensitivity model checks were also performed, resulting in reliable regression analysis that can be generalized to various situations. The results of the study suggest that increased religiosity is associated with a decrease in per person ecological footprint. This research suggests a transformation of religious values towards a more inclusive eco-religious perspective, encompassing bio-centric and eco-centric ethics, and not just anthropocentric views. Collaboration between religious and non-religious communities is key in addressing climate change. Religious institutions are also identified as essential agents in mobilizing environmental movements, participating in international forums, and incorporating climate change issues into educational curricula. This research supports the potential of religiosity as a positive catalyst in global efforts to preserve environmental sustainability and address the holistic challenges of climate change.

Published: March 2024

This paper considers the comparative analysis of the physical and mathematical methods of the optimal operation of aviation objects’ automatic control systems, which is an urgent scientific and technical task. The paper also represents the corresponding stability criteria, depending on the operating conditions, and the influence of external factors that allows ensuring the automatic control systems’ reliable operation not only in normal circumstances, but also in the presence of probable disagreements. The scientific novelty of the research lies in developing new stability criteria by means of synthesising the influence of different factors and also the ability to ensure optimal functioning of the automatic control systems. Corresponding mathematical and computer models have been developed. The use of these models allows to determine the optimal stability criteria for control systems with parameters of a different physical nature and ensure reliable operation of electromechanical systems for general and special applications based on the current analysis. The research results are illustrated by corresponding mathematical models, engineering calculations and modelling of the optimal control limits depending on the influence of various factors. The simulation results coincide with the theoretical calculations, which indicates the consistency between the microprocessor-based and software of automatic control systems.

Authors: Hassan Waseem , Naveed Asif
Published: March 2024

Background:
An increased incidence of vertebral artery dissection has recently become a recognized cause of acute stroke for about 1/5 of strokes in young patients.
Case Presentation:
A male in his 30s presented to the emergency department with sudden onset of severe vertigo, vomiting, and dizziness while he was playing bowling. The symptoms started when he suddenly twisted his neck while throwing the ball towards pins. Initial diagnosis of central vertigo led to performing plain CT head and CT head angiogram, which demonstrated non-occlusive extradural left vertebral artery dissection. Following CT scans, an MRI head, and MRA head and neck were performed which confirmed the CT diagnosis and also showed left posterior inferior cerebellar artery territory infarcts with micro haemorrhages. The patient was started on dual antiplatelet medications which was continued for 6 months with a follow up MRI/MRA scan of head and neck.
Conclusion:
This appears to be a unique case where sudden twisting of the neck possibly resulted in vertebral artery dissection and cerebellar infarction. Hence, it is vital to be aware of sports related presentation resulting in sudden neck movements and tear in vertebral artery causing dissection.

Kaji Teoritis Pengaruh Variasi Letak Retak Terhadap Perambatan Retak Dengan Pendekatan Double Cantilever Beam (DCB)
Authors: Dahlan Hendery , Rusli Meifal , Bur Mulyadi , Hadiguna Rika Ampuh
Published: March 2024

One of the causes of structural failure is the presence of defects in the form of cracks that appear during the manufacturing or usage process of the structure. The propagation of cracks in the structure greatly depends on the value of the energy released rate possessed by the defective structure. Therefore, it is necessary to calculate the energy released rate of a structure that has a crack. One simple approach is the double cantilever beam (DCB) method. The DCB approach is derived from the change in strain energy with respect to the change in crack length. In this study, variations in crack length and crack location will be analyzed using the DCB approach and compared with the Finite Element Method (FEM) approach. It can be concluded that the calculation of strain energy can be performed using the cantilever beam approach, where the results do not significantly differ from the FEM calculations. Additionally, the strain energy is heavily influenced by the length of the beam, as longer beams result in a significant increase in strain energy (cubic relationship). The value of Energy Released Rate (ERR) is highly influenced by the crack length; a longer initial crack length leads to a quadratic increase in the Energy Released Rate (ERR). Furthermore, the value of Energy Released Rate (ERR) is also affected by the crack location; the closer the crack is to the surface of the beam, the higher the Energy Released Rate (ERR) will be.

Penelitian tentang pengaruh waktu sonikasi terhadap struktur dan sifat magnet nanokomposit Fe3O4@GO telah dilakukan. Sintesis nanokomposit dilakukan dalam tiga tahap. Tahapan pertama, preparasi nanopartikel Fe3O4 dengan menggunakan metode kopresipitasi. Kedua, preparasi GO dari daun pisang kering menggunakan metode Liquid Sonication Exfloitation (LSE). Tahap terakhir yaitu pelapisan permukaan Fe3O4 dengan GO membentuk Fe3O4@GO menggunakan proses sonikasi dengan variasi waktu 30 menit, 60 menit, dan 90 menit. Nanokomposit dikarakterisasi menggunakan X-ray diffraction (XRD), fourier transform infraRed (FTIR), dan vibrating sample magnetometer (VSM). Ukuran kristal sampel Fe3O4, Fe3O4@GO (30 menit), Fe3O4@GO (60 Menit), dan Fe3O4@GO (90 menit) yang diperoleh dari hasil karakterisasi XRD berturut-turut yaitu 18,47 nm; 18,48 nm; 14,79 nm; dan 21,14 nm. Struktur kristal yang didapat dari semua sampel yaitu Fe3O4 berbentuk cubic dan GO berbentuk rhombohedral.. Hasil karakterisasi FTIR semua sampel Fe3O4@GO yang disonikasi menunjukkan adanya ikatan Fe O dan C C yang mengindikasikan terbentuknya Fe3O4 dan GO. Dari pengujian VSM diperoleh semua sampel bersifat superparamagnetik. Waktu sonikasi tidak mempengaruhi bentuk struktur kristal nanokomposit Fe3O4@GO, namun mempengaruhi sifat kemagnetannya. Semakin lama waktu sonikasi maka semakin besar nilai magnet saturasi dan nilai koersitivitas nanokomposit Fe3O4@GO. Berdasarkan nilai saturasinya, Fe3O4@GO dapat dikembangkan dalam aplikasi biomedis seperti diagnostik dan fototermal.

The study's focus is on Indonesia's 415 Regencies and Cities from 2015 to 2021. Certain government spending indicators are employed in panel data regression as independent variables using Eviews 9.00. Secondary data were collected from the Central Bureau of Statistics (BPS) and the Ministry of Finance (MoF). The results of model 1 show that of the eight variables used to see their effect on per capita income, there are six variables that have a favorable impact, namely health budget allocations, public service functions, social protection functions, village funds, regional independence and investment, while education fund allocations and the economic function is unable to increase per capita income in Indonesia. The outcomes of model 2 demonstrate that components of model 1's influence on per capita income have a favorable impact on Indonesia's Human Development Index.
