A Scalable Sharding Protocol Based on Cross-Shard Dynamic Transaction Confirmation for Alliance Chain in Intelligent Systems
Authors: Sun Nigang , Li Junlong , Liu Yining , Arya Varsha
Published: November 2023

Applying sharding protocol to address scalability challenges in alliance chain is popular. However, inevitable cross-shard transactions significantly hamper performance even at low ratios, negating scalability benefits when they dominate as shard scale grows. This article proposes a new sharding protocol suitable for alliance chain that reduces cross-shard transaction impact, improving system performance. It adopts a directed acyclic graph ledger, enabling parallel transaction processing, and employs dynamic transaction confirmation consensus for simplicity. The protocol's sharding process and node score mechanism can deter malicious behavior. Experiments show that compared with mainstream sharding protocols, the protocol performs better when affected by cross-shard transactions. Moreover, its throughput has shown improvement compared to high-performance protocols without cross-shard transactions. This solution suits systems requiring high throughput and reliability, maintaining a stable performance advantage even as cross-shard transactions increase to the usual maximum ratio.

Published: November 2023

A healthy diet and daily physical activity are a cornerstone in preventing serious diseases and conditions such as heart disease, diabetes, high blood pressure, and hypertension. They also play an important role in the healthy growth and cognitive development for young and old people. Thus, this paper presents a new restaurant advisory system (RAS) using artificial intelligence (AI) techniques such as machine learning, decision tree, and rule-based methods. The proposed system makes a smart decision based on the user's input information to generate a list of appropriate meals that fit his/her health condition. For accuracy and efficiency measurement procedure in the decision-making process, a dataset from 1100 participants suffering from several diseases such as allergy, age, and body has been created and validated. The performance of the RAS was tested using Visual Basic.net Framework and prolog language. The RAS achieves an accuracy of 100% by testing 30 different live cases.
Transformaciones institucionales y currículares en la educación técnico-profesional para mujeres en la provincia de Santa Fe (1966-1983)
Authors: D'Ascanio Gabriela
Published: November 2023

En este artículo desarrollamos las ideas que orientaron los objetivos que asumió la educación técnica, profesional y artesanal femenina y la política educativa santafesina orientada a las escuelas técnico profesionales para mujeres, entre 1966 y 1983, para analizar las transformaciones y las permanencias de la oferta. Desde el origen del sistema educativo argentino, la formación para el trabajo de las mujeres en actividades productivas fue excluida de la educación secundaria. Reconocemos que en Santa Fe, se mantuvo esta característica hasta mediados de la década de 1970, cuando se comenzaron a implementar nuevos planes de estudios que vincularon los currículos profesionalistas con la enseñanza media, que se afianzaron recién al comienzo de la década siguiente aunque en un nivel de calificación inferior al de técnico.

Published: November 2023

Mucormycosis is an angioinvasive infection, especially among immunocompromised patients. There are several forms of the disease and rhino-orbito-cerebral mucormycosis is the commonest presentation globally, especially among patients with diabetes mellitus with or without ketoacidosis. We report a patient with rhino-orbito-cerebral mucormycosis involving multiple cranial nerve palsies.A 70-year-old female patient with uncontrolled diabetes mellitus presented with left periorbital swelling and reduced vision on the same side along with epistaxis. On examination, she was found to have multiple cranial nerve palsies. She was managed as rhino-orbito-cerebral mucormycosis after performing several microbiological, histological, and radiological tests. The patient was discharged after 4 months of hospital stay.Despite successful medical and surgical interventions, the patient died a week after being discharged from the hospital. Though we have no strong evidence, the disease itself, her co-morbidities, sepsis, and surgical trauma could have contributed to her death.

Published: November 2023

Leontiasis ossea (LO) in chronic kidney disease patients, also known as Sagliker syndrome, is an exceptionally uncommon uremic complication of long-lasting and severe secondary hyperparathyroidism. The prominent features of uremic LO (ULO) encompass the characteristic clinical trial of massive thickening of maxillary and mandibular bones, widening of interdental spaces, and flattening of nasal bridges and nares. Moreover, during the transformation of craniofacial architecture, significant structural and functional consequences may appear, including upper airway patency, visual and hearing acuity, oral phase of swallowing as well as various neurological and psychiatric disorders. Only few cases of ULO have been reported in the literature until now, making challenging not only the traditional diagnostic procedures but also the optimal therapeutic approach. In this narrative review, we aim to explore the underlying pathophysiological mechanisms, summarize the evidence for adverse outcomes, and highlight the current therapeutic strategies for ULO prevention and treatment, given that precise genetic determinants remain elusive.
Are Health-care Professionals Meeting Patient’s Expectations? – A Comparative Study Done in Emergency Setup of a Teaching Hospital in North India
Authors: Garg Kashypi , Nagendran Subramaiah
Published: November 2023

Background:

User satisfaction in healthcare is an important measure of the quality of services provided to the patient and their carers. Since treatment of psychiatric patients requires long follow-up periods, and this long follow-up treatment patients depends on their initial experience with health service, therefor user satisfaction is of increasing importance in the mental health field. Aims and Objectives: Assess the user satisfaction and perceptions of the attitude of emergency health-care professionals (including paramedical staff and physicians of respective specialties) toward psychiatric and nonpsychiatric patients as experienced by the patients and carers. To compare the user satisfaction and perceived attitude of emergency staff in patients with psychiatric illness and nonpsychiatric illness. To determine the service users’ decision to revisit the same health-care facility in case of the same problem.

Materials and Methods:

This study was done in the hospital wing of a tertiary care teaching university hospital in northern India, and ethics approval was obtained from the institutional ethics committee patients’ sociodemographic details and psychiatric and other relevant medical history after obtaining informed consent. The psychiatric diagnosis was made according to the ICD-10. A self-report questionnaire, comprising 9 questions, and was designed to assess the perceived attitudes of health-care workers toward the patient of psychiatric illness. The questionnaire was designed in Hindi. Descriptive statistics for categorical variables were done. Inferential statistics were calculated using the Chi-square test.

Results:

Out of a total of 95 respondents, 69 patients were diagnosed with a psychiatric disorder and the remaining 26 patients had medical illness or other non-psychiatric disorders. Females were a majority in both groups. Our study majorly showed that service users perceived the attitudes of medical and paramedical staff in emergency units mostly as satisfactory or extremely satisfactory, as well as the majority of service users reported that they were satisfied with the reaction of emergency paramedical staff towards the emotional well-being of the patient.

Conclusions:

The major strengths of this study were the quantitative analysis of health workers’ attitudes toward patients with psychiatric illnesses, which showed user-rated satisfactory attitudes. There was less stigma and more of a positive impact noted. The semi-structured questionnaire was designed in the local language and tailored to cover topics such as emotional well-being and psychoeducation that can all affect the user experience.
Covariates Associated with Mental Health Problems Faced by Undergraduate Medical Students Undergoing Competency-Based Medical Education at a Rural Institution in North India: A Cross-Sectional Exploratory Survey
Authors: Kharb Aakanksha , Garg Sunny , Yadav Akanksha , Yadav Ekta , Kumar Sumit
Published: November 2023

Introduction:

Mental health-related problems among medical students were well-researched before the era of competency-based curricula. These problems were revealed to be widespread among college students who experienced greater effort-reward imbalance and over-commitment. Such research is insufficient in the Indian context.

Aims:

The present study aims to assess the prevalence of mental health problems (stress, anxiety, and depression), and their covariates among female medical undergraduate students.

Methodology:

A cross-sectional exploratory study was conducted from March 2022 to May 2022 on 364 female medical undergraduate students in a rural institution located in Northern India. A stratified random sampling technique was used. The study included a semi-structured sociodemographic with personal and psychological domains proforma along with a Perceived Stress Scale-10, Generalized Anxiety Disorder-7 questionnaire, Becks Depression Inventory-II, Medical Students Stressor Questionnaire, and brief-coping orientation to problems experienced to assess perceived stress, anxiety, depression, stressors, and coping mechanisms, respectively. The Chi-square test and backward multivariable logistic regression analyses were used to investigate the correlates of dependent variables.

Results:

Of 364, around 40.7%, 36.5%, and 17.9% of students were highly stressed, anxious, and moderate to severely depressed, respectively, with a mean age of 20.44 ± 1.88 years. The results indicate that poor sleep and irregular exercise patterns were significant covariates of mental health problems. Respondents with interpersonal- and intrapersonal-related stressors were found to have two times (adjusted odds ratio [AOR] = 2.632; confidence interval [CI] = 1.216–5.698; P < 0.05) and four times (AOR = 4.230; CI = 1.832–9.763; P < 0.001) higher odds of perceived stress and anxiety symptoms, respectively. A personal history and family history of psychiatric illness among participants influenced perceived stress by 211%–226% while drive- and desire-related stressors influenced depressive symptoms by more than three times (AOR = 3.719; 95% CI = 1.702–8.124; P < 0.001).

Conclusions:

Findings from the present study suggest that a large number of students are suffering from mental health issues. Modifiable factors such as poor sleep and irregular exercise patterns can be addressed through various wellness programs and group sessions. Various supportive and preventive measures along with scheduled psychological interventions can be adopted by the institution to address various stressors faced by the students.
Finnish Variety of Congenital Nephrotic Syndrome in Association with Cytomegalovirus Infection
Authors: Lohia Shraddha , Jose Georgeena Elsa , Pote Prahlad D.
Published: November 2023

Background:

The term “congenital” is used for cases of nephrotic syndrome (NS) that manifests in the first 3 months of life. They are rare diseases mainly due to genetic causes but sometimes attributed to congenital infections. The prognosis depends on the type of mutation in the former and whether remission occurs with specific therapy in the latter.

Clinical Description:

We describe an 11-week-old baby who presented with generalized edema and features of septic shock that responded to antibiotics. The presence of hypoalbuminemia, proteinuria, and hypercholesterolemia completed the clinical phenotype of NS. Mesangioproliferative glomerulonephritis was confirmed on histopathology. The presence of persistent hepatosplenomegaly, neurological findings, decreased head circumference, and poor nutritional status prompted us to investigate for congenital infections. Positive antibody levels for Cytomegalovirus (CMV) and positive polymerase chain reaction confirmed CMV infection, though we were unable to establish whether it was congenital or acquired postnatally. A novel genetic mutation (c. 712+1G>C) was identified in the NPHS 1 gene.

Management:

The baby was initiated on specific antiviral therapy and attained partial remission of renal symptoms after 4 weeks. The patient was lost to follow-up after 6 months.

Conclusion:

The coexistence of the Finnish variety and CMV infection might have caused the severity of phenotype. The authors emphasize the importance of performing a genetic test in cases of congenital NS and also working up for acquired causes on an individualized basis.
Hypoparathyroidism Precipitated by Mumps
Authors: Vyas Varuna , Khera Daisy , Didel Siyaram , Yadav Taruna , Singh Kuldeep
Published: November 2023

Background:

Hypoparathyroidism is a condition characterized by hypocalcemia and hyperphosphatemia due to insufficient secretion of parathyroid hormone (PTH). The common causes of hypoparathyroidism are postsurgical and autoimmune. We describe a case of hypoparathyroidism precipitated by mumps.

Clinical Description:

A 17-year-old boy was brought to us with altered sensorium following 2 episodes of generalized tonic-clonic seizures within the last 4 h. He required mechanical ventilation, but severe laryngospasm made intubation difficult. He had been suffering from a febrile illness that appeared to be mumps for the preceding 4 days. The only salient biochemical abnormality was hypocalcemia and hyperphosphatemia. Neuroimaging and cerebrospinal fluid examination were normal. Hypoparathyroidism was suspected and confirmed by low PTH levels. He also developed secondary hypothyroidism.

Management and Outcome:

The child had no symptoms of hypocalcemia in the past. He was started on intravenous calcium and calcitriol. He showed dramatic improvement in sensorium with normalization of serum calcium levels. He was extubated after a week. At discharge, there were no neurological sequelae and the sick euthyroid syndrome had resolved. Viral serology for mumps was reactive by the 3rd week of illness.

Conclusion:

Although viral infections have been described as triggers for other endocrinopathies, we could not find any association with hypoparathyroidism. An exhaustive literature search we could not find any similar case reports of hypoparathyroidism during or following mumps. Whether mumps infection had any role in the pathogenesis of the hypoparathyroidism or only unmasked an underlying endocrinopathy remains uncertain.

Published: November 2023

Background:

Thrombotic thrombocytopenic purpura (TTP) is a rare disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, acute renal failure, and central nervous system impairment.

Clinical Description:

Although most cases of TTP are idiopathic, there are some case reports describing its association with certain infections. We report a rare case of TTP associated with tuberculosis which was confirmed by ADAMTS13 levels.

Management:

This child was managed with high-dose plasma infusion.

Conclusion:

To the best of our knowledge, this is the first case in a pediatric patient with this association and treated successfully by high-dose plasma infusion.
Chylomicron Retention Disease in an Indian Infant
Authors: Mathur Radhika , Chandane Parmarth , Shah Ira , Prabhu Sanjay , Bodhanwala Minnie
Published: November 2023

Background:

Chylomicron retention disease (CRD), or Anderson disease, is included in the familial hypocholesterolemia syndromes. Blockade of transport of chylomicron from the endoplasmic reticulum to the Golgi apparatus at the cellular level results in a total absence of chylomicron and apolipoprotein B-48 in the blood circulation following a fat meal. This is associated with a deficiency in liposoluble vitamins and essential fatty acids.

Clinical Description:

We report the clinical, laboratory, and histological details of a 7-month-old boy who presented with recurrent vomiting, steatorrhea, abdominal distension, and failure to thrive since early infancy. On examination, he had severe acute malnutrition, pallor, dry skin, and hepatomegaly.

Management and Outcome:

Investigations revealed anemia, normal liver function test, amylase, and hypocholesterolemia. Endoscopy showed fat-laden duodenal mucosa with inflammation and vacuolization of the enterocytes. This prompted genetic testing for CRD which was confirmed by a homozygous deletion encompassing exonic regions of 3–7 of SAR1B gene on chromosome 5 [c.(178 + 1_179-1)_ * 1_]. Our patient was treated with a low-fat diet, allowing only essential fatty acids, and supplementation with fat-soluble vitamins. There was a gradual improvement in weight gain.

Conclusion:

Common fat malabsorption disorders presenting in childhood have significant failure to thrive. CRD should be suspected in infants with early-onset steatorrhea, if a typical blood lipid profile and endoscopy/biopsy findings are seen. CRD is confirmed by the detection of a mutation in the SAR1B gene.
Role of Impedance Plethysmography in Detecting Dysautonomia and Vascular Changes in the Dysglycemic Milieu of Gestational Diabetes – A Case–Control Study
Authors: Bhat Smitha , Sudeep K , Jain Rajesh K.
Published: November 2023

ABSTRACT

Introduction:

Gestational diabetes, which is defined as any degree of glucose intolerance first seen during pregnancy, is increasing in prevalence in India. Gestational diabetes and Type 2 diabetes share the common pathophysiological factor of insulin resistance; mothers with gestational diabetes are more prone to developing Type 2 diabetes. The hyperglycemia and metabolic abnormalities in Type 2 diabetes are associated with microvascular complications such as, retinopathy, nephropathy, and neuropathy, including autonomic neuropathy. Autonomic neuropathy, especially cardiac autonomic neuropathy because of diabetes, is an important cause of mortality and morbidity. Impedance Plethysmography (IPG) is based on the principle that the volume of the arterial and venous pulses can be derived from the electric properties of blood. The peripheral pulse thus analysed shows morphological patterns that are specific for different diseases. Although various morphological patterns have been mapped with different diseases, the waveform of gestational diabetes has not yet been explored. Hence, this study aimed to find whether gestational diabetes affected peripheral blood flow in a way that could be detected by IPG, resulting in a specific waveform pattern. Additionally, as previous research on the effect of gestational diabetes on the autonomic nervous system shows conflicting results, this study aimed to determine whether gestational diabetes is associated with autonomic dysfunction that can be detected by IPG.

Materials and Methods:

This was is a case–control study conducted on 98 antenatal mothers. The IPG patterns of 50 mothers with gestational diabetes were compared with demographic, clinical data, and IPG waveforms of 48 age-matched controls.

Results:

We found that the heart rate variability, an indicator of autonomic nervous system function, was impaired in mothers with gestational diabetes. We did not find that gestational diabetes was associated with a specific waveform on IPG.

Conclusion:

Gestational diabetes is associated with autonomic dysfunction in the form of impaired heart rate variability that can be detected by IPG.

Authors: Bhardwaj Bikram , Kachatti Sushila S. , Singh Randeep
Published: November 2023

ABSTRACT

A malignant mixed mullerian tumour (MMMT) is a rare tumour that primarily affects the uterus. MMMT of the ovary is very rare, contributing to 1% of ovarian carcinomas. It is an aggressive cancer of the ovary with characteristics of two types of cancers—carcinoma and sarcoma. A common presentation is a postmenopausal lady with a mean age of 65 years with complaints of abdominal mass, pelvic pain, and vaginal discharge. We report here a rare presentation of abnormal uterine bleeding in a peri-menopausal woman with an abdomino-pelvic mass, abdominal distension , post-coital bleed and abdominal pain, who underwent staging laparotomy with a preoperative diagnosis of malignant ovarian lesion and was found to have a malignant mixed Mullerian tumour of the ovary on histo-pathological examination. She is doing well at present after receiving six cycles of chemotherapy for Stage 2A disease. Diagnosis of malignant mixed mullerian ovarian tumours are difficult to confirm clinically because histopathological examination reports are required. This entity is rare and has poor prognosis. However, our patient is doing well to date.

Authors: Antony Joseph T. , Sankarlingam Rajeswari , Chilukuri Balaji , Maheshwari Rashi , Chinnadurai Saranya
Published: November 2023

ABSTRACT

Background and Objectives:

Psoriatic arthritis (PsA) and gout are conditions sharing several common risk factors. Serum uric acid levels are commonly raised in both, and it is observed that many patients presenting with gout have either clinical or family history of psoriasis. There are case report of overlapping PsA and gout called “Psout.” So the objective of this study was to find out ultrasonographic features of gout in patients with PsA.

Methods:

This was a prospective observational study conducted on 105 PsA patients. Serum uric acid and ultrasonography (USG) with color Doppler of the affected joint were performed to look for the presence of the double contour (DC) sign, snowstorm sign, and erosion that is specific for gout. The sensitivity of “tophus,” “snowstorm,” and the DC sign-on USG were 46%, 30.3%, and 60.1%, while the specificity was 94.9%, 90.9%, and 91.4%, respectively, for gouty arthritis. The sensitivity, specificity, positive predictive value, and negative predictive value of hyperuricemia (uric acid levels >6.8 mg/dL) were compared with USG findings in diagnosis of psout.

Results:

The prevalence of gout in PsA was 11.4% (12/105); 10/12, 2/12, 6/12, and 1/12 had DC sign, tophi, erosions, and snowstorm appearance, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of hyperuricemia in diagnosis of gout in PsA was 33.3%, 86%, 23.5%, and 90.9%, respectively.

Conclusion:

Psoriasis and gout can co-exist or mimic each other. Good presence of DC sign-on USG is a noninvasive method to diagnose gout in PsA patients. Those patients not responding to treatment for PsA may have co-existing gout, so we recommend USG in all patients with PsA, especially if they are not responding to treatment.
A Study Towards Building Content Aware Models in NLP using Genetic Algorithms
Authors: Tank Umesh , Arirangan Saranya , Paduri Anwesh Reddy , Darapaneni Narayana
Published: November 2023

INTRODUCTION: With the advancement in the large language models, often called LLMs, there has been increasing concerns around the usage of these models. As they can generate human-like text and can also perform a number of tasks such as generating code, question answering, essay writing and even generating text for research papers.OBJECTIVES: The generated text is subject to the usage of the original data (using which models are trained) which might be protected or may be personal/private data. The detailed description of such concerns and various potential solutions is discussed in ‘Generative language models and automated influence operations: Emerging threats and potential mitigations’. METHODS: Addressing these concerns becomes the paramount for LLMs usability. There are several directions explored by the researchers and one of the interesting works is around building content aware models. The idea is that the model is aware of the type of content it is learning from and aware what type of content should be used to generate a response to a specific query.RESULTS: In our work we explored direction by applying poisoning techniques to contaminate data and then applying genetic algorithms to extract the non-poisoned content from the poisoned content that can generate a good response when paraphrased.CONCLUSION: While we demonstrated the idea using poisoning techniques and tried to make the model aware of copyrighted content, the same can be extended to detect other types of contents or any other use cases where content awareness is required.
Second class particles and limit shapes of evacuation and sliding paths for random tableaux.
Authors: Maślanka Łukasz , Śniady Piotr
Published: November 2023

We investigate two closely related setups. In the first one we consider a TASEP-style system of particles with specified initial and final configurations. The probability of each history of the system is assumed to be equal. We show that the rescaled trajectory of the
second class particle
converges (as the size of the system tends to infinity) to a random arc of an ellipse.

In the second setup we consider a uniformly random Young tableau of square shape and look for typical (in the sense of probability)
sliding paths
and
evacuation paths
in the asymptotic setting as the size of the square tends to infinity. We show that the probability distribution of such paths converges to a random
meridian
connecting the opposite corners of the square. We also discuss analogous results for non-square Young tableaux.
Poisson–Lie group structures on semidirect products

Published: November 2023

We look at the Poisson structure on the total space of the dual bundle to the Lie algebroid arising from a matched pair of Lie groups. This dual bundle, with the natural semidirect product group structure, becomes a Poisson–Lie group as suggested by a recent work of Stachura. Moreover, when we start from the matched pairs given by the Iwasawa decomposition of simple Lie groups, we find that the associated Lie bialgebra is coboundary.

Accurate P-wave reflection and transmission coefficients for non-welded interface incorporating elasto-plastic deformation
Authors: Fan Zihang , Zong Zhaoyun , Chen Fubin
Published: November 2023

P-wave reflection and transmission coefficients for non-welded interface play crucial roles in broad practical engineering productions, involving fracture properties prediction and seismic inversion. However, the existing reflection coefficient equations for non-welded interface in elasto-plastic media are seldom studied, although the elasto-plastic deformation is frequently encountered in the Earth’s subsurface due to artificial and tectonic activities. In this study, we proposed the accurate reflection and transmission coefficients equation for a non-welded interface embedded in an elasto-plastic deformed medium based on the elasto-plastic acoustoelastic and linear-slip theory. In detail, this paper uses elasto-plastic acoustoelastic theory to derive the reflection and transmission coefficients equation. The reflection and transmission coefficients matrix are solved using the linear-slip theory as the boundary condition. Moreover, we use the hardening parameter and plastic deformation to represent the plastic properties of the rock, which is a function of stress and plastic deformation. Through Numerical analysis, the deformation caused by static stress has significantly changed the amplitude and the slope of the reflection and transmission coefficients amplitude. As the stress increases, the rock’s velocity becomes higher, and all reflection and transmission coefficients (i.e., RPP, RPS, TPP, TPS) abruptly change at the critical angle. Furthermore, with the increase in plastic deformation, the critical angle of the incident P-wave and the hardening parameter becomes larger than the unstressed state. The non-welded interface exhibits a low-pass frequency filter for reflected SV-waves and a high-pass frequency filter for reflected P-waves and transmitted P and SV waves. In addition, we can observe that static vertical stress can weaken the anomalous reflections caused by non-welded formations, but the effect is insignificant. On the other hand, the effect of fracture normal compliance to reflection and transmission is detailly investigated. When N<2.5*10-10(MPa-1), The non-welded interface is close to the welded interface, while N>2.5*10-5(MPa-1), the non-welded interface is close to the solid-air interface.
Physiological processes in Phalaenopsis pulcherrima cultivated in hermetically sealed vessels
Authors: Zaimenko Natalia , Didyk Nataliya , Kharitonova Iryna , Viter Arsen
Published: November 2023

The hermetic condition is the least studied factor associated with the spaceflights. Phalaenopsis pulcherrima is promising for space farming as it can be cultivated in small substrate blocks, and its photosynthetic apparatus is well adapted to elevated CO2 concentrations and temperatures.Three-year-old meristematic P. pulcherrima plants were planted into plastic (acrylic) vessels filled with fibrous substrate. In control, vessels had an open top. The hermetic conditions were reached by sealing the vessels’ covers with a parafilm. Both control and hermetic vessels were placed in a plant growth chamber where test plants were cultivated under controlled conditions of air temperature, illumination, air humidity, and soil moisture. After 6 and 24 months of cultivation, the CO2 concentration in the hermetic and control vessels was measured, and the physiological characteristics of each test plant, such as the content of macro- and micronutrients, photosynthetic pigments, free amino acids, and content of labile carbohydrates (%) in the leaves of the test-plants were determined.It was revealed that cultivation of P. pulcherrima in hermetic conditions affected its basic physiological processes such as photosynthesis, mineral nutrition, carbohydrates, and amino acid metabolisms. The effect size of this stress factor depended on the duration of exposition period. Long-term cultivation of P. pulcherrima under hermetic conditions promoted the accumulation of nonenzymatic antioxidants (viz. chlorophyll b, carotenoids, and amino acids), which contributed to the adaptation of this orchid species to oxidative stress caused by hermetic environment.
How wrong are we in estimating the abundance of mistletoe occurring on Scots pine? – a case study from Central Europe
Authors: Piętka Jacek , Małecki Michał , Niewiński Krzysztof , Kędziora Wojciech
Published: November 2023

This paper presents data on the occurrence of the semi-parasitic mistletoe plant (Viscum album L.) in a pine stand in central Poland. The number of mistletoe bushes, the percentage of mistletoe in the crown volume, and the location of its occurrence were determined from the ground level on 193 pine trees growing in a 212c subcompartment in the Głuchów Forestry, Rogów Forest Experimental Station. In addition, 15 trees were analyzed in detail after felling to verify the previously obtained results. The age, diameter, and location (top, middle, and bottom of the tree crown) of the shrubs were measured. The study showed that the pine stand analyzed was strongly infested by mistletoe. The number of mistletoe bushes recorded on standing trees from the ground level was significantly lower than that found on trees after felling. An in-depth visibility analysis showed that in some cases, an operator assessing mistletoe bush abundance from the ground level may miss a very large number of juvenile individuals, as well as mistletoe shrubs with large diameters. This is probably related to the clumping of perennial individuals growing in proximity to a single shrub that is visible from the ground. V. album mainly colonizes the apical zone (observations from the ground) and middle zone of the host crown (detailed analysis of mistletoe abundance on felled trees). Older shrubs were most abundant at the apex of the crown, while younger shrubs were most likely to colonize the middle and bottom of the host crown. In a study of felled trees, 289 mistletoe individuals were found on the most infested trees. It was also found that the most numerous shrubs, V. album were young, aged between three and six years. The increase in mistletoe infestations in forests observed in recent years may pose a serious threat to pine stands weakened by abiotic factors.

The right to work is a historical category and institution of labor law that belongs to one of the basic human rights. From the idea of the right to work, which, in the middle of the 19th century, was highlighted by utopian socialists, through the first legal establishment to the fact that in the modern world almost all constitutions guarantee it. Nevertheless, differences still exist today and are reflected in the theoretical understanding of the right to work. On the one hand, emphasis is placed on human freedoms, and viewed in that sense, the right to work is an integral part of the values of a free society, as the freedom to work, that is, to choose an occupation. The right to work is a complex right that does not include the right to concrete employment, because the level of employment of every citizen who is able to work will depend on the level of development of a certain country. So, the right to work is not a subjective right but, first of all, it is a constitutional proclamation, which means that the state should create conditions for smooth economic development with its legal regulations, because only in this way can jobs be secured. On the basis of the Constitution, laws and by-laws were adopted that regulate work, employment, prohibition of discrimination, both when establishing and during the duration of employment relationships, prohibition of abuse at work, social security, etc.

This study aimed to evaluate the effect of the inclusion of either fresh or dried black soldier fly larvae (BSFL) in diets on the production parameters and chemical composition of Thai frogs (Rana rugosa) cultured in net cages. Frog fingerlings have an initial weight of 20.4 g and were distributed randomly into fifteen net cages (2 x 3 x 1.5 m) at a density of 240 frog.net cage-1. Including five dietary treatments named: T1 (100% commercial feed used as a control), T2 (100% dried BSFL), T3 (50% dried BSFL + 50% commercial feed), T4 (50% fresh BSFL + 50% commercial feed), and T5 (100% fresh BSFL) with three replicates for each treatment. The results showed that the survival rate of frogs ranged from 64.3% to 87.0%, improved feed conversion ratio (1.43 to 1.90%), increased live weight (194.7 – 244.6 g), daily weight gain (2.9 – 3.7 g.day-1), and frog’s yield (6.30 – 7.96 kg.m-2). The contents of crude protein (18.21 – 23.19%), ether extract (0.28 – 0.53%), and total ash (0.99 – 1.05%) of frog meat in this study were affected by the inclusion of either fresh or dried BSFL in the diets of frogs. In recommendation, the diet comprised from 50% fresh BSFL + 50% commercial feed could be applied successfully in Thai frog cage production.
