Sludge from Arapaima Gigas Culture as an Alternative Culture Medium for Lipid Production in Nannochloropsis Sp
Authors: Richarte-Enriquez Héctor Joel , Merino Fernando
Published: November 2024

Objective: The objective of this work was to evaluate the use of sludge generated during the culture of Arapaima gigas as an alternative medium for Nannochloropsis sp.
 
Theoretical Framework: Microalgae are photosynthetic micro-organisms with the ability to transform organic waste or effluents into valuable biomass. They are currently of great interest for their use in the food and pharmaceutical industry. Nannochloropsis sp. is a valuable microalga due to its excellent lipid profile.
 
Method: The sludge used was collected from A. gigas culture ponds at the CITE Acuícola Pesquero Ahuashiyacu (Tarapoto-Peru). An aqueous extract of sludge (EAL) was obtained from the sample by a thermal procedure, which was dosed into the cultures at concentrations of 100, 150 and 200 mL/L. The experimental units followed the traditional batch culture arrangement under laboratory conditions. Guillard F/2 medium was used as control treatment. The characterisation of metals in the medium was performed by coupled plasma induction (ICP) and the determination of ammonium and nitrite by colorimetric tests. In addition, population density, productivity and total lipid content were estimated.
 
Results and Discussion: Chemical analyses revealed high concentrations of calcium, sodium, magnesium, iron, potassium, phosphorus, ammonium and nitrite (655, 648, 283, 67, 32, 17, 1.5, and 10 ppm, respectively). Likewise, the best growth (3590.00 ± 91.24 x 104 cells/mL) and productivity (0.69 ± 0.01 g/L) was obtained with 200 mL/L of EAL, presenting significant statistical differences (p < 0.05) with respect to the other treatments. In contrast, the highest lipid production (29.67 ± 1.53 %) was observed in the control treatment, far exceeding the EAL cultures; however, no significant statistical difference was observed between EAL treatments.
 
Research Implications: These results demonstrate the feasibility of using EAL as an alternative medium for the production of Nannochloropsis sp. with a positive environmental and economic impact on the production of A. gigas.
 
Originality/Value: The use of sludge generated in fish culture, in particular A. Gigas, has not been reported previously. In this study, we demonstrate for the first time the feasibility of using this sludge in the culture of the microalga Nannochloropsis sp. which also has a high potential for use in fish larviculture.
Transformation of the functions of the institution of the welfare State: the evolution of views and modern challenges
Authors: Dekhanova Natalia Gennad'evna , Kholodenko Yurii Aleksandrovich
Published: November 2024

The relevance of the chosen issues is determined by the subject of research – the institution of the welfare state, which plays a crucial role in ensuring the normative order in society and the balance of interests between different social groups. It also guarantees the realization of citizens' political and social rights.The study focuses on the transformation of the welfare state's functions and priorities in social policy, influenced by a rapidly changing internal and external environment. The main methodological foundation of the study is theoretical scientific methods and a systematic approach. Due to the interdisciplinary nature of the research, the authors have drawn on both the results of sociological studies and a significant amount of data from international and domestic socio-economic statistics to address the identified issues. The authors have conducted a comprehensive analysis of the factors that contribute to socio-economic change and how these changes directly affect the functioning of the welfare state. They conclude that, despite differences in each country's stable preferences, external and internal socio-economic conditions influence the social functions of states, institutions, and the mechanisms for implementing these functions. Despite the fact that the principles and functions of the welfare state are implemented through specific measures that take into account the economic capabilities of the state, the peculiarities of state-building, national mentality, and the system of basic values, the idea of state paternalism remains at the heart of each model of the welfare state. This idea reflects the concept of state guardianship over the social sphere. In addition, there is a trend towards convergence among models of the welfare state in the modern world, which manifests itself in a steady trend towards unification of mechanisms for implementing social functions of the state and convergence in the scale of redistribution processes.
Prospects and limitations of the implementation of the University's third mission
Authors: Polezhaeva Tatiana Yurievna
Published: November 2024

Today, attention is focused on three main areas of university activity, which are called "missions". These areas include educational and research functions, as well as the transfer of innovations. The third mission of the university means its social responsibility to local communities, participation in the cultural and economic development of the state. The introduction of digital technologies and the processes of globalization have a significant impact on the fields of activity of universities, presenting both challenges and new opportunities for their development. The purpose of this article is to consider the scientific discussion about the third mission of the university, as well as to identify opportunities and limitations in its implementation. The increased use of digital technologies and globalization are leading to changes in higher education, affecting all three levels of university activity. In this work, general scientific approaches to the study of social institutions are applied, in particular, the method of comparative analysis was applied. A review of the literature on the topic is presented, the importance of involving different stakeholders in university education is revealed. Universities are facing new challenges, but there are also prospects for changing the educational process. At the turn of the century, universities were experiencing crisis and decline, and pressure was exerted on them to shift the focus of their activities from the main missions to the third mission, expressed in the wording "responsibility to local communities". Research in this field is often devoted to the traditional tasks facing the university, or they consider the third mission in a narrow sense. However, it is important to identify both the positive consequences and the contradictions that higher education faces at the stage of the emergence of new functions. The university community is also offered a number of measures that could be used to solve the problems that arise.
Soviet patriotism in the context of technological security of the USSR
Authors: Ivanov Andrei Alexandrovich
Published: November 2024

The article examines the history of socialist building in the Soviet Union through the prism of the political leaders’ search for a solution to the problem of designing a new innovation mechanism. The object of the study is the technological security of the USSR, and the subject of the study is the system of motivation for inventions in the situation of a transitional society. The author focuses on the role of various hybrid constructs – for example, «socialist patriotism» – in the formation of such mechanism. Particular attention is paid to the ideological aspects of technological security, namely, the attempts of the country's leaders to combine the doctrins of Marxism with practical steps to create a socialist mechanism for ensuring scientific and technological sovereignty. In the article, the author explains the reason for the Bolshevik leadership’s rejection of the ideas of internationalism by the need to use elements of “patriotic” motivation to intensify technological progress. In the study, the author used an institutional analysis of the development of the Soviet scientific and technological sector in the context of explaining the connections of science with other elements of the social mechanism of the USSR. The novelty of the study lies in identifying the ideological aspects of the state technological security system. The author’s special contribution to the study is in revealing the paradox between the internal structure of the Soviet innovation mechanism and the conflictual coexistence of the socialist and capitalist systems. The main conclusions of the study are the author’s statements about the inconsistency of the policy of the USSR leaders in the field of innovation management and the forced usage of state coercion instruments within the framework of prison-type scientific organizations to overcome the paradoxes of the development of the scientific sector.

Published: November 2024

Pituitary carcinoma is traditionally defined as a tumor of adenohypophyseal cells that metastasizes systemically or craniospinally. They account for approximately 0-2% of all pituitary tumors. Their diagnosis and treatment is challenging. We report the case of a woman who was initially diagnosed with adenoma and scheduled for surgery. An MRI of the brain three weeks later showed metastatic lesions. The patient died ten days after surgery due to adrenal crisis. The development of pituitary carcinoma is extremely unusual. It could be misdiagnosed with an invasive pituitary adenoma. Until recently, treatment of pituitary carcinoma was mainly palliative and did not appear to increase overall survival.

Authors:   The Korean Association of Criminal Psychology, Oh Se Yoon , Kim Sung Hwan
Published: November 2024

This study examined the effects of participation in citizen patrol activities on students' community awareness, fear of crime, awareness of community policing, and confidence in the police, as well as the moderating role of the perceived significance of volunteer activities in these relationships. The study was conducted with students from D University who participated in citizen patrol activities. The analysis model treated participation in citizen patrols as the independent variable, with community awareness (including dimensions such as belonging, interaction, and attachment), fear of crime (both general and specific), awareness of community policing, and confidence in the police as dependent variables. The significance of volunteer activities was considered a moderating variable. The findings indicate that involvement in citizen patrols significantly influences community awareness, awareness of community policing, and confidence in the police. Furthermore, the perceived significance of volunteer activities was shown to have a substantial moderating effect on the relationship between citizen patrol participation and both awareness of community policing and confidence in the police. These results suggest that enhancing the meaningfulness of citizen patrol experiences can amplify their positive impacts, even when these experiences initially appear formal or incomplete.

Authors:   The Korean Association of Criminal Psychology, Seong Gyeongjoo
Published: November 2024

The purpose of this study is to explore the factors influencing hate speech during adolescence and to examine the impact of hate awareness formed during this period on various aspects of adolescent life. For this purpose, publicly available data from the “2020 Study on the Exposure to and Countermeasures for Hate Speech among Adolescents,” conducted by the National Youth Policy Institute of Korea, was used. The analysis included data from 3,938 middle and high school students, excluding missing values. The main research findings based on the analysis are as follows. First, it was found that as experiences of hate speech victimization, the perceived social influence of hate speech, and levels of hate towards minority groups increased, the awareness of hate speech during adolescence also heightened. Second, among the risk factors influencing the awareness of hate speech during adolescence, the social influence of hate speech emerged as the most significant factor. Through this, the aim is to raise awareness among adolescents about social minorities, such as women, individuals with disabilities, and the elderly, emphasizing that they are members of our societal community with whom we must coexist.

Authors:   The Korean Association of Criminal Psychology, Youn Byoung-Hoon , Cho Jin-Kwan
Published: November 2024

Previous studies related to police body-worn cameras have discussed legal and institutional problems and issues that may cause when police officers use them at the scene. In recent years, there has been a possibility that their use will be further expanded due to the revision of related laws after the test project of the police body-worn cameras is closed. This study empirically analyzes the differences among the socio-demographic characteristics of field police officers' perceptions of police body-worn cameras using two variables: citizen/resident reaction and general perception. As a result of the research, differences are identified in the variables of citizens/residents reaction according to the socio-demographic characteristics such as age and rank of the survey subjects. On the other hand, there is no difference in general perception variables according to the socio-demographic characteristics. Based on the results of the study, domestic and international research results are different on citizen/resident reactions, and this study also suggests future discussion directions in that they differ from some socio-demographic characteristics of citizen/resident reactions. This study also differs from existing studies in that no difference is identified in general perception by the socio-demographic characteristics. Through these findings, this study suggests the expansion of empirical research related to police body-worn cameras.

Published: November 2024

Background. Expert rehabilitation assessment of premature infants in the neonatal period and the first months of life presents great difficulties; from this standpoint, it is advisable to introduce the term “habilitation prognosis” (HP) for the category of premature infants. The purpose of the study is to substantiate and develop indicators of habilitation prognosis and habilitation potential of premature infants. Materials and methods. A prospective study was performed. 212 premature newborns were included (n=212), whose data were statistically processed. Two groups were formed: 1st group of medical habilitation MH(+) n=89 patients for whom MH measures were carried out in full in accordance with the main directions of the developed methodology. The other part of the children made up the 2nd group of MH(-) n=123 patients for whom MH was not performed in accordance with the developed methodology: due to parental disagreement, or the impossibility of systematic work, or MH was not performed in full. The post-conceptual age of children at which medical habilitation of premature infants began ranged from 32 weeks to 3 months. Results. A quantitative integrated indicator of habilitation potential for premature infants HPtP (in the range of values from 7 to 35 points) was developed based on the qualitative characteristics of the rehabilitation prognosis (favorable, doubtful, unfavorable). ROC analysis was performed. It has been established that the optimal separation points are: 11 (area under the ROC curve (AUC) AUC=0.8613 95CI [0.8101-0.9124]) and, accordingly, the boundary for establishing a favorable HPtP from 7 to 11 (out of 35 maximum possible) , p<0.001, and 16 (AUC=0.998 0.8613; 95% CI [0.8101-0.9124]) with sensitivity indicators of 0.9716312 (97.2%), specificity 0.9859155 (98.6%), and, accordingly, the limit for establishing unfavorable HPtP from 17 up to 35 points, p<0.001. Conclusion. A quantitative indicator of habilitation potential for premature infants (HPtP) has been developed. For the first time, the term “habilitation prognosis for premature infants” (HPrP), referring to the possibility of realizing the habilitation potential of premature infants under the full application of medical habilitation methods in a certain premature infant was introduced.

Published: November 2024

Background. The study of the heterogeneity and plasticity of astrocytes in the brain, in particular in the peritumoral zone, at different stages of neoplasm growth will help to understand their importance in the progression of glial tumors. Aim. To perform morphometric assessment of astrocytes in the rodent brain during glial tumor progression. Material and methods. Glial brain tumor was modeled in rodents using implantation of glioma C6 cells followed by immunohistochemical assessment of GFAP+-astrocytes in the peritumoral zone in the right hemisphere and a similar zone of the left hemisphere of the rodent brain at different experimental periods. Results. In the early stages of glial tumor growth, there was a statistically significant predominance of cell density and a difference in the morphometric parameters of astrocyte cells in the peritumoral zone of the right hemisphere of the rat brain compared with a similar zone of the left hemisphere. The progression of the glial tumor was accompanied by a significant decrease in the cell density of astrocytes in the peritumoral zone with an increase in reactive changes of astrocytes in a similar zone of the contralateral hemisphere. Conclusions. The development of tumor processes in the brain of rodents is accompanied by activation of astrocytes with the acquisition of a reactive phenotype by cells in the peritumoral zone. At the same time, further progression of the neoplasm suppresses active proliferation of astrocytes.

Published: November 2024

Background. As for now, the level of C-reactive protein (CRP), which may be present in donors with traumatic and non-traumatic brain injuries, has not been reliably established, and its dynamics in patients upon the occurrence of brain death (BD) have not been studied. Objective of this study is to investigate the dynamics of CRP levels in patients with severe irreversible brain damage, which subsequently led to brain death. Material and methods. The prospective study included 106 patients with severe brain damage who were diagnosed with BD despite treatment. The CRP level was determined for patients on the 1st to 10th days of intensive therapy. Results. The CRP level upon admission to the ICU was 13.3 (3.86; 29.1) mg/l. CRP values were within normal limits only in 14 (13.2%) patients. On the 2nd day of intensive therapy, the level of CRP was higher statistically significant – 85 (45.4; 140.6) mg/l, p =0.00004 vs 1 day. On the 3rd day of intensive therapy, the level of CRP was also higher statistically significant – 135.3 (73.6; 238.2) mg/l, p =0.00001 vs 2 days. The CRP values in all patients were higher than the reference values. On the 4th day, the level of CRP in patients became 219.7 (112.7; 326.4) mg/l (p=0.00006 vs 3 days) and did not significantly change in the following days in terms of statistics. Conclusion. The dynamics of CRP levels in patients with severe brain damage can be used as a predictor of unfavorable outcome of intensive care and brain death.

Background. Pruritus is one of the most common symptoms accompanying psoriasis. Patients with pruritus report decreased quality of life, depression, anxiety, and body dysmorphic concerns, as well as reduced effectiveness of treatment. Objective. To study the intensity of skin pruritus and the level of neuropeptides in the blood serum in patients with psoriasis associated with mental disorders. Material and methods. The main methods of examination of 110 patients with psoriasis were clinical and anamnestic method as well as clinical laboratory and clinical psychopathological ones. Results. In patients with a combined variant of psoriasis and mental disorders, a significantly higher incidence of skin pruritus (p <0.001), pain (p <0.01), elevated serum levels of substance P (p˂0.001) was established; significantly more often scratching increased pruritus (p<0.05), pruritus led to depression (p<0.01), pruritus was prolonged (p<0.05) with a significant decrease in quality of life (p<0.05), mood swings were characterized as “severe"(p<0.05) and "unbearable" (p<0.001). Conclusion. Pruritus is one of the most common and bothersome symptoms of psoriasis and is often associated with psychosomatic and psychiatric comorbidities, as well as elevated blood serum levels of certain neuropeptides. This fact may indicate the role of the latter in the pathogenesis of this combined pathology. Considering the possibility of therapeutic potential on the neuropeptides production level, the obtained data on their role in the pathogenesis of psoriasis and its comorbid pathology will allow us to develop a personalized approach to therapy, taking into account the severity of the disease and concomitant pathology.

Central Mervous System involvement (CNS) in Acute Lymphoblastic Leukemia (ALL) can be present at initial diagnosis or at disease relapse and early detection is crucial for prompt intervention. Optic nerve infiltration by leukemic cells is an oncologic emergency that requires urgent therapy to spare vision along with systemic therapy, with limited data about the optimal therapeutic strategy. Isolated optic nerve Involvement at relapse is rare; described in Philadelphia chromosome negative (Ph-) ALL in 2.2% of relapses in children and exceeding rare in Philadelphia chromosome positive (Ph+) cases, particularly in the absence of systemic disease. Here we report isolated unilateral optic nerve involvement as the sole feature of early disease relapse in Ph+ ALL in the absence of systemic disease, leading to early detection of molecular relapse.

Correlation Between NMR Coupling Constants and σ-Donating Properties of N-Heterocyclic Carbenes and Their Derivatives
Authors: Gupta Radhika , Frison Gilles
Published: November 2024

Is the 1JC-H coupling constant for protonated carbene a relevant measure of its σ-donation ability? This paper addresses this question by comparing calculated 1JC-H values with various experimental and theoretical approaches across a broad spectrum of carbene compounds. We have examined not only Arduengo-type NHCs based on the 2-imidazolylidene scaffold but also many other derivatives with modified frameworks, such as carbenes with extended, saturated, or conjugated rings, those with reduced heteroatom stabilization, those stabilized by alternative heteroatoms, permanently charged carbenes, acyclic carbenes, amidocarbenes, and cyclic amino(alkyl/aryl) carbenes, as well as carbodicarbenes and carbodiphosphoranes. Our findings reveal a nuanced relationship between different parameters associated with σ-interaction, such as 1JC-H, Huynh electronic parameter (HEP), σ-donation from ETS-NOCV, and lone pair energy. Notably, the best correlation was observed between 1JC-H and the ETS-NOCV method, particularly for mono- and diaminocarbenes, highlighting the utility of 1JC-H in comparing σ-donation among structurally similar carbene types. However, the use of 1JC-H as a universal measure across all carbene classes appears limited, especially when considering carbenes with significantly different structural frameworks. While HEP is less effective for carbenes with diverse structural backbones, our study suggests that 1JC-H has potential across a broader range of systems. Additionally, the analysis demonstrates that lone pair energy reflects basicity rather than σ-donor ability.

The sulfidation of metal oxides is critical to the creation of catalyst active sites for industrially-relevant reactions, but occurs at high temperatures for refractory oxides like zirconia. Here, we investigate sulfidation of the structurally-well-defined, Zr-based metal-organic framework (MOF) NU-1000 as a model system. Sulfidation with H2S and alkane thiols occurred readily at room temperature after thermal distortion of the Zr6 clusters in NU-1000. The sulfidation occurred via heterolytic S-H bond cleavage over frustrated Lewis-acid/Lewis-base pairs in the form of under-coordinated Zr(IV) sites and a terminal O(-II) site formed during the thermal distortion. In situ synchrotron based structural analysis, spectroscopic characterization, and computational studies provide evidence that thiols react with distorted Zr6 nodes to form stable bridging Zr-S-Zr bonds and a terminal hydroxo. This study provides insight into the surface structures responsible for the sulfidation of high-valent metal oxides and also suggests a promising strategy for introducing S-bearing moieties to otherwise sulfur-resistant MOF nodes.
Minimum Energy Conical Intersection Optimization Using DFT/MRCI(2)
Authors: Wang Tzu Yu , Neville Simon P. , Schuurman Michael S.
Published: November 2024

The combined density functional theory and multi-reference configuration interaction (DFT/MRCI) method is a semi-empirical electronic structure approach that is both computationally efficient and of predictive accuracy for the calculation of electronic excited states and simulation of electronic spectroscopies. However, given that the reference space is generated via a selected-CI procedure, a challenge arises in the construction of smooth potential energy surfaces. To address this issue, we treat the local discontinuities that arise as noise within the Gaussian progress regression framework and learn the surfaces by explicitly incorporating and optimizing a whitenoise kernel. The characteristic polynomial coefficient surfaces of the potential matrix, which are smooth functions of nuclear coordinates even at conical intersections, are learned in place of the adiabatic energies and are used to optimize the DFT/MRCI(2) minimum energy conical intersection geometries for representative intersection motifs in the molecules ethylene, butadiene, and fulvene. One consequence of explicitly treating the noise in the surfaces is that the energy difference cannot be made arbitrarily small at points of nominal intersection. Despite the limitations, however, we find the structures as well as the branching spaces to compare well with \textit{ab initio} MRCI and conclude that this approach is a viable method to learn a smooth representation of DFT/MRCI(2) surfaces.
Stable ammonia synthesis at milder and intermittent conditions on laser-induced graphene supported barium promoted Ruthenium catalyst
Authors: Nowrin Fouzia Hasan , Malmali Mahdi
Published: November 2024

Graphitized carbon material derived from laser irradiation of polyimide film (PI) has been utilized for the first time to synthesize barium-promoted ruthenium catalysts for mild ammonia synthesis. The degree of graphitization was modified through thermal treatment in a reactive carbonizing gaseous environment to investigate the influence of the surface properties of laser-induced graphene (LIG) on the activity of Ru-Ba/LIG catalysts. Untreated LIG-based catalysts exhibited superior activity compared to thermally treated LIG catalysts. Particle agglomeration and removal of oxygen functional groups from treated LIGs, confirmed by characterizations, were identified as the reasons for reduced catalytic activity. The LIG-supported Ru catalyst was further tested under various operating conditions, achieving an optimal production rate of 31500 μmol g-1 h-1 for the 5 wt.% Ru-2.5 Ba (Ba/Ru molar ratio) catalyst at 400°C and 1 MPa. The catalyst demonstrated stability over a period of 25 days and maintained performance under intermittent operating and process conditions. Additionally, the catalyst exhibited resistance to hydrogen poisoning. Several characterization techniques were employed to elucidate the surface properties of the LIG-supported catalyst. The graphitic nature of untreated LIG, combined with its oxygen functional groups, fosters a strong metal-support interaction, thereby enhancing the performance of the Ru-based catalyst.

Small molecule solubility is a critically important property which affects the efficiency, environmental impact, and phase behavior of synthetic processes. Experimental determination of solubility is a time- and resource-intensive process and existing methods for in silico estimation of solubility are limited by their generality, speed, and accuracy. This work presents two models derived from the fastprop and chemprop architectures and trained on BigSolDB which are capable of predicting solubility at arbitrary temperatures for any small molecule in organic solvent. Both extrapolate to unseen solutes 2-3 times more accurately than the current state-of-the-art model and we demonstrate that they are approaching the aleatoric limit (0.5-1 logS), suggesting that further improvements in prediction accuracy require more accurate datasets. These models, collectively referred to as fastsolv, are open source, freely accessible via a Python package and web interface, highly reproducible, and up to 50 times faster than the next best alternative.
Zorlayıcı Diplomasi ve KKTC Basınında S-300 Füzeleri Krizi
Authors: Gülbay Alper
Published: November 2024

S-300 Füzeleri Krizi, Güney Kıbrıs Rum Yönetimi (GKRY)'nin Rus yapımı S-300 füzelerini satın aldığının öğrenilmesi üzerine patlak veren bir dış politika gelişmesidir. Kriz boyunca Türkiye, gücünü savaş boyutuna taşımadan dolaylı bir şekilde kullanmış, "zorlama stratejisi" izleyerek Yunanistan-GKRY ikilisinin geri adım atmasını sağlamıştır. Türkiye- Yunanistan/GKRY uyuşmazlığının ötesinde olan bu gerilimin Doğu Akdeniz'de stratejik ve askeri dengeleri sarsacağından endişe edilmiş; sorun, Amerika Birleşik Devletleri (ABD), Avrupa Birliği (AB), Kuzey Atlantik Antlaşması Örgütü (NATO), İngiltere gibi aktörlerin müdahil olmasıyla çok taraflı bir boyut kazanmıştır. 1997'de GKRY'nin AB'ye tam üye yapılmasının öngörülmesinin vermiş olduğu ivmeyle Yunanistan-GKRY ikilisi, S-300 füzeleri sayesinde adada Rus varlığına olanak sağlayarak, tırmandırma siyaseti kapsamında pazarlık gücünü artırmak istemiştir. Bu çalışma, Türkiye'nin dış politika bağlamında hangi adımları izleyerek Yunanistan-GKRY ikilisine geri adım attırdığını, bölgesel ve küresel aktörlerin sürece niçin ve nasıl müdahil olduğunu ve gelişmelerin KKTC basınında nasıl yer bulduğunu irdelemektedir.

Status of Sarus Crane (Grus antigone, Linn.) in Madhya Pradesh, India
Authors: Ghosh Suchitra , Chatterjea N. N. , Mookherjee Kushal , Poddar Adrish , Ghosh A. K.
Published: November 2024

The Sarus Crane (Grus Antigone, Linn.) is considered Vulnerable at the international level by IUCN but has been included in Schedule IV of Indian Wildlife Protection Act, 1972 amended till date. One of the largest and the most dominant species in India, which has been declared as the State Bird of Madhya Pradesh, logically deserve serious studies on its current status. In the present study, special focus was given to the preferred habitats i.e., large agricultural farmland and wetland areas, which are distributed in 26 districts of the state. In addition 07 more districts were also surveyed in two years period. During the survey, direct sightings along with geo-references have been recordedand photographed.. Additional information were collected by interacting with the local community and meticulously recorded. A total of 347 individual birds were recorded through direct sighting during the project period and if one adds the reports from the local community, the total number of birds now stands at 491 birds. But one has to remember the limitation of this methodology, which does not exclude the possibility of repeat sighting of the same bird at a different location. As such, to exclude such possibilities, same day census operation at all the selected locations, by deploying large number of ground staff, could be undertaken in future.Besides incorporating the data on the locations and sightings, suitable recommendations have been made towards its conservation action, especially focusing on the need for extensive Public Awareness Programme through appropriate visual display. It has also been pointed out that land use changes, both in case of large agricultural land and water-spread areas should be appropriately controlled as a part of State Policy for conserving the State Bird of Madhya Pradesh.
