Signal-to-noise errors in early winter Euro-Atlantic predictions caused by weak ENSO teleconnections and pervasive North Atlantic jet biases
Authors: O'Reilly Christopher
Published: September 2024

Long-range winter predictions over the Euro-Atlantic sector have demonstrated significant skill but suffer from systematic signal-to-noise errors. In this study we examine early winter seasonal predictability in 16 state-of-the-art seasonal forecasting systems. Models demonstrate skill in the hindcasts of the large-scale atmospheric circulation in early winter, which mostly projects onto the East Atlantic pattern. The predictability is strongly tied to the ENSO teleconnection to the North Atlantic, though the models' response to ENSO is systematically too weak. The model hindcasts of the East Atlantic index exhibit a substantial signal-to-noise errors, with the models predicted signal generally being smaller than would be expected for the observed level of skill. The signal-to-noise errors are found to be strongly dependent on the strength of the ENSO teleconnection in the models, with models with a weaker teleconnection displaying a larger signal-to-noise problem. It is demonstrated that the dependency on model ENSO teleconnection strength can be explained using a simple scaling relationship derived from a toy model. Further analysis reveals that the strength of the ENSO teleconnection in the model is linked to climatological biases in the behaviour of the North Atlantic jet. Models that better represent the dynamics of the jet over the northern part of the basin - with more frequent poleward jet excursions and less frequent Greenland blocking - are better at representing the ENSO teleconnection to the North Atlantic in early winter, with lower associated signal-to-noise errors.
Humor Self-Concepts and Personality: Locating Humor Efficacy and Identity Beliefs Within Extraversion, Openness, and Imagination
Authors: Silvia Paul Joseph , Rodriguez-Boerwinkle Rebekah , Karwowski Maciej
Published: September 2024

People’s beliefs about their ability to be funny, like their creative self-beliefs more generally, are important to understanding their creative goals, actions, and achievements in the domain of humor. Paralleling general creative self-concepts, humor self-concepts consist of humor self-efficacy (“I can” confidence beliefs about one’s ability to be funny) and humor identity (“I am” beliefs about the centrality of being funny to one’s sense of self). The present research explored how these beliefs relate to Extraversion and Openness to Experience, two major traits in humor research, and to a recent model of Imagination. An online sample of adults (n = 307) completed multiple measures of the many aspects and facets of these traits along with the Humor Efficacy and Identity Short Scales. Random forest models were used to disentangle the many correlated aspects and facets and to estimate their unique predictive importance. Humor self-efficacy was primarily marked by being intellectually imaginative and socially outgoing, and secondarily by being energetic, active, and assertive. Humor identity was primarily marked by being sociable and imaginative. These profiles reinforce the social nature of humor as a creative practice and suggest differences in how personality relates to humor beliefs versus humor abilities.

Authors: Solaiman Barry
Published: September 2024

This Article considers how health technologies using Al can be used to expand access to care today within existing regulatory conﬁnes in the United States. Embedded within that discussion are legal and ethical considerations that are important to the facilitation of such technologies for providing care. There will be regulatory changes in the years to come, and it is beneﬁcial to highlight where the law currently stands. In this regard, this Article provides a modest overview of remote care solutions and a guide to three central legal considerations that arise in using AI for remote care. These considerations should form part of the criteria used to evaluate any exploratory discussions for new health devices.
Mortality Anxiety and Aesthetic Engagements: A Reading in Katherine Anne Porter's Pale Horse, Pale Rider
Authors: Bhattarai Kedar
Published: September 2024

The article analyses the effect of performance arts (dance, music, and writing) on the central character Miranda in Katherine Anne Porter's novella Pale Horse, Pale Rider. The study situates itself within the discourse of pandemics and the discourse of expressive arts. In addition to establishing the correspondence between mortality anxiety and aesthetic engagements, it explores the testimonies of performance arts in Pale Horse, Pale Rider and its impact on its central character Miranda who lives a stressful life induced by the Spanish influenza of 1918 and World War I. Dancing, singing, and writing are expressive activities that belong to the world of aesthetics and senses. Besides, as the findings of the study suggest, they are affirmative responses of Porter against the war and pandemic of 1918. They offer pleasure, ecstasy, escape, and liberty.
Rebel Body against the Caste System in Ahuti's "Gahungoro Africa"
Authors: Shah Saroj Kumar
Published: September 2024

Applying body politics, this research paper attempts to explore the rebel body against the caste system in Ahuti's "Gahungoro Africa". First published in Mulyankan monthly magazine in 2051, the poem "Gahungoro Africa" satirically airs its voice against those oppressors who exploit Dalit laborers in different ways. The poet raises the issue of Dalits considering them touched or untouched during the caste system. The researcher makes a strong argument that the so-called low-caste Dalit people should be given the right to justice and freedom at any cost by abolishing caste discrimination entirely. The speaker of this poem is a leading figure, the rebel body as well as the voice of downtrodden, underprivileged, and working-class Dalit laborers against the so-called high caste. The paper shows the conflict between the so-called high caste; the exploiter, landlords, and touchable Vedic body, and the so-called low caste; the exploited, slaves, and untouchable non-Vedic body, especially the Dalit bodies who are declared 'untouchable' by the socially construct Hindu caste system. The poem carries out a very sarcastic, challenging, and angry tone toward the so-called high caste and its agents.

Short- versus Long-Term Follow-Up Ultrasound Examinations of Biopsy-Proven Benign Thyroid Nodules
Authors: Kehoe Breanna
Published: September 2024

Background

Current guidelines suggest indefinite follow-up ultrasound examinations and repeat fine-needle aspiration biopsies (FNABs) be conducted on biopsy-proven benign thyroid nodules depending on their sonographic appearance. The current guidelines are due to the false-negative rate associated with FNABs. The purpose of this review is to determine whether short- versus long-term follow-up ultrasound examinations increase the detection rate of malignancy for individuals with biopsy-proven benign thyroid nodules.

Methods

A systematic review was conducted of retrospective studies in which the follow-up of biopsy-proven benign thyroid nodules was assessed and it was identified whether malignancy in the form of papillary thyroid carcinoma (PTC) was detected.

Results

Searches in 3 databases (using the key terms follow-up studies, ultrasonography, thyroid nodule, and biopsy), as well as 3 additional sources, resulted in 53 unduplicated articles. Six full-text articles were assessed for eligibility upon meeting the initial inclusion criteria. Ultimately, 2 studies were included in the systematic review which examined the number of, and reasons for, patients undergoing thyroidectomy or lobectomy after having repeat ultrasound examinations and repeat FNABs in short- (<3 years) or long-term (>3 years) intervals. Results showed that short-term follow-up detected 7 additional malignancies due to a variety of factors including repeat FNAB findings and suspicious ultrasound features. Long-term follow-up detected 3 additional malignancies, however, the reason for resection was largely due to symptomatology.

Conclusion

Indefinite follow-up of biopsy-proven benign thyroid nodules is costly and may be unnecessary. Short-term follow-up using ultrasound has been shown to increase the detection rate of malignancy. However, the use of ultrasound for long-term follow-up has not proven to increase the detection rate of malignancy. It may prove beneficial to review the current best practice guidelines and implement a change in practice.
A Review of the Triangular Fibrocartilage Complex Tear and its Sonographic Features
Authors: Chen Mengling
Published: September 2024

The triangular fibrocartilage complex (TFCC) serves as a major stabilizer of the ulna-carpal space, however, there is no official guideline on how to investigate a TFCC tear on ultrasound and there is little to no protocol on how to scan this structure. Although small, the complexity of the relational anatomy should not be underestimated. Hence there are several difficulties in recognizing anatomy and distinguishing the tears on Ultrasound. The use of 10-15 MHz high-frequency linear transducer is allowing sonographers to include TFCC examination as part of the wrist ultrasound. Two classification systems of TFCC tears and different treatment options will be discussed, comparing the existing treatment method and new emerging techniques.
Use of Duplex Ultrasound Imaging Post-Endovascular Aneurysm Repair (EVAR)
Authors: Gullipalli Ravindra , Hartery Angus , Martin Heather
Published: September 2024

Individuals who undergo endovascular aneurysm repair (EVAR) require annual surveillance to detect endoleaks and guide surgical management. Endoleaks are classified into five categories based on the direction of blood flow in the aneurysmal sac outside the graft, determining prognosis and management. Currently, evaluation with computed tomography angiography (CTA) is favored as the gold standard for evaluation of endoleak. However, there is associated patient exposure to nephrotoxic intravenous contrast as well as radiation. Each of the five subtypes of endoleak can be characterized and subsequently followed on ultrasound. This practice offers a safe and cost-effective alternative to CTA.

Abstract: Systematic Labeling of Twin Pregnancies on Ultrasound
Authors: Dias T. , Ladd S. , Mahsud-Dornan S. , Bhide A. , Papageorghiou A. T. , Thilaganathan B.
Published: September 2024

Objective:

Correct labeling of twin fetuses is needed for consistency in assigning and interpreting longitudinal scan and prenatal screening/diagnostic results. The aim of this study was to describe a standard method of twin labeling in the first trimester of pregnancy and to assess the robustness of such a technique in predicting the presenting twin in subsequent scans and at delivery.

Methods:

This was a retrospective first-trimester study of all twin pregnancies assessed by ultrasonography at our center between 2000 and 2010. The fetus contained in the gestational sac closer to the maternal cervix was designated as Twin 1 and the relative orientation of the fetuses to each other was then defined as either lateral (left/right) or vertical (top/bottom). In discordant-sex twins, their sex and presenting order on the final scan prior to delivery were documented and compared with the sex and birth order at delivery.

Results:

A total of 416 twin pregnancies were seen during the study period. At the 11-14-week scan 90.9% of twins were in lateral orientation while the remainder were oriented vertically. None of the vertically oriented twin pairs but 32 (8.5%) of the laterally oriented twin pairs changed their presenting order between the first and the last ultrasound scan prior to delivery. There were 108 discordant-sex twins scanned in the third trimester, of which the birth order changed in 20.3% that were delivered by Cesarean section and in 5.9% of those delivered vaginally.

Conclusion:

The study demonstrates that antenatal labeling of twins according to laterality or vertical orientation is reliable. The technique ensures continuity of biometric assessment from serial scans at each visit, and as such should be adopted as the preferred method of twin labeling. Furthermore, the use of orientation for antenatal labeling of twins rather than assignment of a number based on proximity to the cervix, precludes any misconception regarding which twin will be born first and ensures that parents and pediatricians are aware of the significant likelihood of a peripartum switch.
Sonography of Multiple Anterior Tibialis Muscle Herniations
Authors: Li Tony Y.
Published: September 2024

This article documents the first case of an ultrasound study on multiple anterior tibialis muscle herniations. The patient had multiple hernias in one leg and a solitary hernia in the other. The sonogram demonstrated a similarity between the multiple hernias and the solitary one. Power Doppler sonography revealed vascular involvement in all of the hernias or margins of the fascial defects, which provided evidence to support the postulation that the constitutional defects of the hernias might be related to fascial weakness in the vessel perforation sites.
Bilateral Ectopic Pregnancy: A Case Study
Authors: Klyn-Hesselink Heather
Published: September 2024

The incidence of ectopic pregnancy is climbing due to increasing tubal damage associated with infection, surgery, and assistive reproductive technologies. With this comes a rise in abnormal cases being presented for diagnosis and the risk of them being incorrectly handled. Bilateral ectopic pregnancies are one such abnormality, where their frequency has been so low that the differential tends not to come to mind when managing a patient with ectopic symptoms. The case study presented describes this occurrence, with the second ectopic pregnancy being missed on initial diagnosis only to be discovered when β-hCG levels failed to decline. The prognosis for a missed ectopic gestation is poor, with rupture being the most common and severe complication, making accurate diagnosis and management of bilateral ectopic pregnancy critical to patient care.
Implementing Change in a Sonography Department
Authors: Hendry Jared , Panis Chris , Frederick Krystie
Published: September 2024

Sonography departments need to implement change, although the topic has not been studied in the context of sonography. When change is well managed, employees are positively affected, leading to happier, more productive sonographers with fewer absences. This paper will examine the theories of William Bridges and John Kotter, leaders in the field of change management, and the role of the limbic brain in employee resistance to change. Bridges’ three-step model of transitions is explored, and Kotter's eight-step process for leading change is recommended as the model to implement change. If Kotter's eight-step process is used in conjunction with the understanding provided by Bridges’ model, and the limbic brain's reaction to fear, it is possible that change can be implemented more effectively in general, cardiac, and vascular sonography departments.

Published: September 2024

Out of every 100 adults living in North America, 4 to 7 will have a palpable thyroid nodule and 19 to 67 will have a non-palpable nodule demonstrated by ultrasound (US). Despite a 2.4X increase in detection of thyroid cancer over the last 30 years, the 5-year mortality rate has been stable at around 2% since 2005. This could be due to many factors, but one apparent significant contributor is the over-diagnosis of malignant nodules, likely based on better detection rates from US imaging. It has been estimated that more than half of papillary thyroid cancer nodules (the most common type of thyroid cancer) would not have resulted in clinical symptoms during the life-time of the patient if left alone. With US now able to detect cysts as small as 1mm, and solid nodules in the range of 2-3 mm, physicians are left with a difficult decision in determining which nodules require a fine-needle aspiration (FNA) and which are better left alone. To aid with this difficult decision, standardized evidenced based guidelines were developed by various groups and organizations. Of these, thyroid image reporting and data system (TI-RADS) and American Thyroid Association (ATA) 2015 guidelines are the most commonly used in our institution (The Ottawa Hospital). While these efforts to create a standardized system are helpful in determining which nodules require FNA, the basis of these decisions has to come from high-quality imaging technique. However, a retrospective study at our institution found that there was large discrepancy in imaging technique used by technologists when imaging the thyroid. We suggest, at any point of thyroid imaging (pre, during and post FNA) a standardized technique be used in assessment. Providing all necessary imaging data will allow radiologists to produce a sufficiently detailed report, synthesize the findings, and ensure the best management plan possible for each patient. Future work by technologist associations may help establish more robust imaging standards for this patient population.
Osteoarthritis and Sonography
Authors: Mavety Bridget
Published: September 2024

Osteoarthritis (OA) is described as a pathological process in which the cartilage protecting long bones degenerates. This degeneration, along with other sonographic indications of OA, are evident with sonography. Osteoarthritis is relevant to a sonographer due to its high occurrence rate in the patient population. The occurrence rate increases as age rises which is particularly relevant in recent years because of the increasing age of the baby boomers.

Although common, the etiology of OA is not fully understood. Risk factors include both systemic factors and local biomechanical factors. The degeneration of the cartilage in the affected joints is irreversible however there are methods that are believed to minimize the risk factors that may cause the OA to worsen. Signs and symptoms of OA include joint stiffness, swelling and tenderness. Although there is no treatment for OA, there are preventative measures that can be taken to prevent one's risk.

Authors: Balalaieva O. , Chychkarov Ye. , Zinchenko O. , Serhiienko A. , Kovalov O.
Published: September 2024

The paper analyzes the possibilities of using deep learning neural networks for the implementation of text processing information systems, substantiates the prospects of this technology and the possibilities of its improvement. The possibility of using the MNIST database of handwritten digits on, as well as the EMNIST database of handwritten letters and numbers, namely the EMNIST Letters set, was considered. The research object was modelled in IDEF0 and IDEF3 notations for the «AS-IS» option. It was found that «Building a dataset for model training» and «Choosing a convolutional neural network architecture» are the most frequently asked questions. Reengineering measures are proposed, namely, the expediency of using, in addition to the well-known EMNIST and MNIST sets, a set of handwritten and italic fonts with Ukrainian glyphs, additionally created as part of the work, is shown. For this purpose, modern IT tools such as the Pillow library, Image Data Generator and the Scikit-Learn package were used to select training and test samples. Also, in addition to the initially proposed simplest CNN architectures of the Lenet type, the use of more complex architectures of the AlexNet and VGG-16 types is proposed. Taking into account the proposed reengineering measures, IDEF0 and IDEF3 diagrams were constructed for the «TO-BE» option. The paper analyzes in detail the results of recognizing handwritten Ukrainian letters and Arabic numerals using 6 different CNN architectures using a synthetic data set for training. The research presented in the work was carried out using a software application developed in the Python programming language using the Scikit Learn package, which provides the user with the ability to recognize handwritten text using a multilayer perceptron. carried out precisely using the developed program. It is justified that, in contrast to simple Lenet-type architectures, it is more appropriate to use more complex options, namely the VGG-16 type architecture. Experimental studies of the influence of the number of CNN parameters of different architectures on the recognition accuracy and training time of the neural network have been carried out. Also analyzed are the results of character recognition when recognizing images that do not belong to the training or test sample
Method of determining the trajectory of seismic equipment in the stationary character of sea towing
Authors: Kalinichenko Y.V. , Postnikov Y.Y.
Published: September 2024

Over the past 50 years, the search for natural gas reserves to meet the needs of enterprises and farms has become more and more relevant. The main method of finding mineral deposits is seismic exploration. In connection with the reduction of resources on land, seismic exploration in the sea is promising, as evidenced by the high rate of development of marine seismic technology. And modern technologies in the field of seismic exploration have ensured the popularity of methods of searching for minerals both at sea and in the world as a whole. Since determining the trajectory of the movement of seismic equipment during a fast maneuver relative to the main course is a complex multidimensional task, it is advisable to use an analytical method. The analytical method will allow to study the dynamics of seismic equipment taking into account a number of assumptions and limitations. A complex of special equipment is used for conducting seismic exploration at sea, which includes on-board and off-board components. Seismic equipment should be considered as a low-sea facility. During a quick maneuver, the seismic equipment moves to a certain angle instantaneously relative to the tug, as a result, the movement of the seismic equipment should be considered non-linear. As a rule, seismic equipment is placed on ships with a wide stern, on which the suspended equipment is fixed. The research in the article is based on the use of well-known methods of scientific research: system analysis, risk management theory, mathematical modeling methods for determining maneuvering and movement indicators of the tugboat and seismic equipment. The article improves the method of determining the trajectory of seismic equipment in the stationary mode of sea towing. The peculiarity of the method is the replacement of the movement of the towing vessel and the seismic equipment with their characteristic points, which makes it possible to consider the trajectory of the movement of the seismic equipment as a gentle curve with rapid and moderate changes in the course of the tug, to determine during towing various kinematic characteristics of the shallow-water object and to take them into account when developing the towing project for a variety of environmental conditions in compliance with shipping safety standards
Determination of dynamic component reactions in support bearings of rotor saws for cutting hot rolled (message 2)
Authors: Ishchenko А.O. , Karpenko T.M. , Kapustin S.V.
Published: September 2024

For modern rolling production, the issue of strength and reliability of rotary saw designs, which are designed for cutting hot rolled products, is relevant. One of the factors that reduces the reliability of a rotary saw is the insufficient durability of the bearings of the shaft of the high-speed disk, which perceives the cutting forces. Practice shows that the applied methods of calculating the strength of support bearings do not allow taking into account all possible factors that affect the reliability of bearings in the cutting process. First, as it turned out, during operation, the saw blade has a radial beat, possibly due to an error when cutting the teeth of the blade and the eccentric landing of the blade on the seat when replacing it. Also, due to the fact that the process of cutting with a rotary saw is very short-term, the cutting force is considered to be the impact force. The purpose of this work is to determine the durability of the bearings of the disc shaft of a rotary saw, considering such factors as the radial beating of the disc and the shock load during the cutting process. As you know, during long-term operation of the object, the place for landing the cutting disc on the faceplate wears out, sometimes there is an error in the hole when making a new disc. Therefore, there is an eccentricity of the center of gravity of the disc. The presence of this eccentricity is considered in the work when determining the required forces using D'Alembert's principle of conditional balancing of forces. Given that the duration of cutting is a short-term process (lasts 0.105 sec.), when determining the reactions in the supports of the disk shaft that occur under the action of cutting forces, it is possible to consider the cutting process as an impact phenomenon. Due to the fact that the process of cutting with a circular saw is very short-term, the cutting force is considered the impact force. The magnitudes of the reaction forces in the bearings are determined during cutting using the theorems of impact dynamics: the theorem of impulses and the change of kinetic moment. For the possibility of theoretical determination of the effect of disk beating on the reaction in the bearings of the bearing shaft, experimental studies of disk beating and determined cutting forces were carried out

Published: September 2024

The article examines the optimization of high-alkaline cylinder oil consumption in lubrication systems of marine low-speed engines (MODs), as well as the peculiarities of operation of the cylinder lubrication system in view of modern trends in the development of low-speed marine engines. An overview of the lubricator lubrication systems of the cylinders of marine main engines was carried out and possible prospects for improving the lubricator lubrication systems of the cylinders of marine diesel engines were considered. Attention is paid to the causes of occurrence and methods of combating a whole range of problems, which represent the possibility of increased wear of cylinder sleeves, pistons, piston rings, this is related to the type and grade of fuel and its sulfur content. Sulfur in the fuel is neutralized with the help of cylinder oils with high alkalinity, problems arise when changing the grade of fuel, this requires changing the brand of cylinder oil (CLO BN). The possibility of using a cylinder oil mixing system (ACOM) to neutralize sulfur in the fuel and improve protection against low-temperature corrosion of MOD cylinder liners is proposed and considered. This system mixes and doses cylinder oil depending on the load of the ship's engine and the type of fuel. ACOM allows the dosing of oil on marine engines operating in dual fuel consumption (SDF) modes, where the ratio between pilot (ignition) and gas fuel is defined, the system mixes two different types of cylinder oil into one with the required BN base number, it can be determined as the oil's ability to neutralize acids produced during use. The results of optimal consumption of cylinder oil, which ensures minimal wear of cylinder liners of a diesel engine, are given. Features of lubrication regimes and control of the technical condition of the cylinder group of marine low-speed diesel engines during their operation at reduced rotation frequency are described

Hasil penelitian ini menunjukkan bahwa hubungan antara capaian siswa dalam menyelesaikan soal-soal HOTs dengan persepsi siswa terhadap kemampuan HOTs yang dimilikinya sangat lemah dengan keofisien korelasi 0,09. Hasil penelitian ini menunjukkan bahwa persepsi tentang kemampuan HOTs yang dimiliki oleh siswa tidak diikuti dengan capaian siswa tersebut dalam menyelesaikan HOTs. Hasil ini membuktikan bahwa proses pembelajaran yang dilakukan di kelas harus ditekankan pada aktivitas pembelajaran yang berfokus pada pembiasaan cara berpikit tingkat tinggi untuk siswa, sehingga siswa terbiasa menggunakan HOTs dalam menyelesaikan masalah yang dihadapinya dimasyarakat.

Los sistemas de abastecimiento de agua potable son esenciales para garantizar que el suministro de agua sea adecuado y esté en óptimas condiciones, la investigación realizada tuvo como objetivo encontrar zonas en donde se presentan fugas de agua no visibles en las redes de distribución internas y externas, mediante el uso de un geófono, para la implementación de un mapa de calor en isometría y la aplicación de medidas correctivas en base a normativas vigentes. La metodología empleada responde a un estudio de campo con el uso del geófono AquaTest T10, recogiendo datos de niveles de ruido para plasmarlos en un mapa de calor que mostró una representación visual basada en un código de colores. Se reportó que existía un incremento considerable del nivel de ruido en el baño de mujeres del primer piso y en la caja de válvulas del cuarto piso, en estas ubicaciones se presume que existen posibles fugas de agua. Existe una correlación entre el tamaño de la fuga y la dificultad para encontrarla, es decir que cuanta más pequeña sea la fuga, más difícil será su localización y viceversa, en este sentido, en el presente trabajo se realizaron la mayor cantidad de mediciones
Women Becoming Practitioner Researchers

Early career researchers (ECRs) in education bring unique histories of professional practice and development into academic research communities. Women Becoming Practitioner Researchers explores autoethnographies of twelve women who were, or still are, schoolteachers in the process of becoming researchers. Using autoethnography to disrupt the established systems that distance researchers from their research, the chapters in this volume are curated to apply theory to this important transition. This theory as method approach provides a foundation for understanding as the authors’ weave threads of identities and experiences into their roles as practitioner researchers.

Efforts to increase food security require innovation in reducing the level of use of chemical fertilizers by utilizing organic fertilizers. The aims of the research are: 1) is the application of liquid organic fertilizer from aloe vera able to increase the production of pakcoy plants, 2) is the application of liquid organic fertilizer from rice washing water effective in increasing the production of pakcoy plants, and 3) is there an interaction between the application of liquid organic fertilizer made from aloe vera? crocodiles with liquid organic fertilizer made from rice washing water on the growth rate of pak choy plants. The method used is an experimental method with a Completely Randomized Design (CRD) with two (2) factorial levels. The first factor uses liquid organic fertilizer from rice washing water with 2 doses, namely B0 (without treatment); B1 (with 12.5 ml dose of liquid organic fertilizer from rice washing water). The second factor uses aloe vera liquid organic fertilizer with doses: L0 (without treatment); L1 (5ml dose); L2 (10ml dose); L3 (15ml dose) and L4 (20ml dose). Each factorial is repeated 3 times. The results of the research found that the use of liquid organic fertilizer from aloe vera was able to increase pak choy production effectively with maximum treatment at a dose of 20 ml, apart from that the use of liquid organic fertilizer from rice washing water at a dose of 12.5 ml also has a real influence on increasing pakchoy production. However, in the interaction between the two liquid organic fertilizers, no significant interaction was found between the two types of organic liquid fertilizer during the research process.

The blood coagulation system is actively involved in the development of cancer. It is known that many solid tumors express tissue factor, a “trigger” of the cascade of plasma coagulation reactions, which leads to an increased risk of cancer-associated thrombosis and venous thrombosis in cancer patients. It has also long been known that platelets - small cellular fragments that are the basis of blood clots - play a critical role in metastasis by binding to the tumor cell after it enters the blood vessel, “shielding” it from the immune system and promoting the adhesion and extravasation of the tumor cell into tissues and the formation metastasis. In addition, platelets, being mobile “storehouses” of growth factors, are actively attracted and, in some cases, consumed by the tumor, which contributes to its development and vascularization. Platelet attraction occurs both through activation of the blood coagulation system in the tumor area and through exposure of the adhesive surface by the tumor. Activated in the tumor vicinity, platelets attract and induce neutrophil activation and the formation of neutrophil extracellular traps (NETs), thereby modulating the tumor microenvironment. When activated, platelets are known to secrete a variety of growth factors that promote both tumor development and vascularization. In addition to direct interaction, platelets and tumor cells exchange mRNA, micro-RNA and other regulatory molecules through microvesicles, while platelets are containers for the spread of tumor genetic material (circulating nucleic acids) throughout the body. In this review, we consider the molecular mechanisms of platelet participation in the development and metastasis of solid tumors, and also discuss possible options for pharmacological interruption of this interaction.

Morphological changes in the adrenal glands of male Wistar rats were studied after intramuscular injection of dalargin (a synthetic analog of leuenkephalin) in a model of post-traumatic stress disorders (PTSD). According to the results of testing in the T-maze and the elevated plus maze (ECL), the rats were divided into groups: active of the low anxiety (ALA), active of the high anxiety (AHA), passive of the low anxiety (PLA), passive of the high anxiety (PHA). In ALA rats after injection of dalargin in the PTSD model the thickness of the fascicular zone (zF) of the adrenal cortex increased by 14%, the area of nuclei in zF cells by 9.5%, and the area of the medulla by 21%. With the development of a PTSD-like state in AHA rats, the thickness of the zF increased by 10%. After injection of dalargin in the PTSD model the thickness of the zF was like control. With the development of a PTSD-like state in PLA rats, the thickness of the zF increased by 17%, and the area of zF cells nuclei, the area of the adrenal medulla and the area nucleis adrenal medulla are decrease by 10.5%, 41% and 8%, respectively. After injection of dalargin in the PTSD model area of the adrenal medullas nuclei decrease more by 7%. In PHA rats after injection of dalargin in the PTSD model the thickness zF increased by 23%. It was concluded that the effect of dalargin on the morphometric parameters of the adrenal glands in modeling PTSD is determined by individual typological features of behavior.
