Experimental Investigation of Heat Transfer Characteristics of Automobile Radiator using Tio2 Nanofluid Coolant
Authors: M Vijayakumar. , G Mahendra.
Published: April 2022

Abstract: The use of nanoparticle dispersed coolants in automobile radiators improves the heat transfer rate and facilitates overall reduction in size of the radiators. In this study, the heat transfer characteristics of water/propylene glycol based TiO2nanofluid was analyzed experimentally and compared with pure water and water/propylene glycol mixture. Two different concentrations of nano fluids were prepared by adding 0.1 vol. %, 0.2 vol. %, 0.3 vol. % and 0.4 vol. % of TiO2 nanoparticles into water/propylene glycol mixture (60:40). The experiments were conducted by varying the coolant flow rate between 3 to 6 lit./min. for various coolant temperatures (50°C, 60°C, 70°C, and 80°C) to understand the effect of coolant flow rate on heat transfer. The results showed that the Nusselt number of the Nano fluid coolant increases with increase in flow rate. At low inlet coolant temperature the water/propylene glycol mixture showed higher heat transfer rate when compared with Nano fluid coolant. However at higher operating temperature and higher coolant flow rate, 0.3 vol. % of TiO2nanofluid enhances the heat transfer rate by 8.5% when compared to base fluids.

Published: April 2022

Periodically-driven systems are ubiquitous in science and technology. In quantum dynamics, even a small number of periodically-driven spins leads to complicated dynamics. Hence, it is of interest to understand what constraints such dynamics must satisfy. We derive a set of constraints for each number of cycles. For pure initial states, the observable being constrained is the recurrence probability. We use our constraints for detecting undesired coupling to unaccounted environments and drifts in the driving parameters. To illustrate the relevance of these results for modern quantum systems we demonstrate our findings experimentally on a trapped-ion quantum computer, and on various IBM quantum computers. Specifically, we provide two experimental examples where these constraints surpass fundamental bounds associated with known one-cycle constraints. This scheme can potentially be used to detect the effect of the environment in quantum circuits that cannot be classically simulated. Finally, we show that, in practice, testing an n-cycle constraint requires executing only O(n) cycles, which makes the evaluation of constraints associated with hundreds of cycles realistic.

The government continues to make efforts to increase village development. This is evidenced by the implementation of one of the programs in the form of the establishment of Village-Owned Enterprises (BUMDes). BUMDes was established based on the principles that characterize this business unit. These principles is such as cooperative, balance, tranparansi and accounting. These principles must be implemented in financial management carried out by BUMDes. One of them happened at BUMDes in Bogo Village. This village has the uniqueness as a tourist village, namely kelor village. In the village, BUMDes is also established, Unit Dagang and Kelompok Wanita Tani (KWT) which has made financial statements. Through the qualitative approach used by the researcher and interviewing some of the information in this study, the results are obtained if in terms of transparency, the financial reports that have been prepared in each period have met transparency. This is evidenced by the financial statements that have been prepared and have been informed to the Village Head and local village officials. However, on the other hand, the financial statements they did are not comply with the standards that have been put in place by the Government. Therefore, the need to adjust the financial statements of BUMDes in Bogo Village to the standards set by the Government and the encouragement of cooperation conducted by bogo village with related agencies for the performance of BUMDes is getting better.

A REVIEW OF TIME MANAGEMENT FACTORS IN CONSTRUCTION PROJECT DELIVERY
Authors: Shehu Suleiman
Published: April 2022

A recurring challenge encountered by numerous stakeholders globally in the building construction sector is delay in project delivery. Time management is an indispensable chain among numerous processes required to achieve successful project delivery. In the built environment there is a common consensus that timely completion, quality criterion and completion within cost estimate are the major performance deliverables considered in appraising the successes of construction project. However, poor compliance with time management processes occasioned with paucity of information on specific principles as well as practices influencing time management seems to have contributed a lot to failure on timely delivery of construction project most especially in Nigeria. The study was conducted using qualitative research design in which information was basically obtained from available literature sources which were sorted out and categorized in to relevant factors. This paper finds out through review factors relevant to successful construction project delivery. Findings revealed that thirty-one (31) time management factors were identified and categorized in to: influencing processes, principles and practices. In conclusion, time management per se is actually managing our behaviours in relation to time. Hence, this study recommends solutions that will ensure effective and efficient construction project delivery.

Published: April 2022

The 1982 United Nations Convention on the Law of the Sea (UNCLOS 1982) adheres that a rule-based maritime order is a rudimentary concept of international law. The 2016 award by the Permanent Court of Arbitration (PCA) on the South China Sea (SCS) has led to the continuous Chinese psychological maritime warfare in the Philippine Exclusive Economic Zone (EEZ). The foreign policy of the President of the Republic of the Philippines (RP) has led to contradicting statements of Philippine government officials in protecting the West Philippine Sea (WPS) from the People’s Republic of China (PRC). With the 1992 ASEAN Declaration, the regional bloc may have its jurisdiction over the case; however, their principle of non-interference prevents any mechanism to settle the maritime dispute. While both juridical and political aspects were considered in resolving the Timor Sea case through conciliation, Article 298 of UNCLOS 1982 becomes the core legal collision in the SCS. Despite experts, organisations, and institutions proposing democratic initiatives through digital activism, securing and defending the WPS, however, the broader Indo-Pacific requires the democratic diplomacy recourse of a mini-ASEAN youth to coordinate with the youth from the Quad and the G7 countries to multilaterally raise the concern at the United Nations.
A Race to the Frontier: Invoking Peripheral Territories - Case of Sabah as a Regional Player
Authors: Anwar Ariff
Published: April 2022

This article explores how Sabah could utilise its geopolitical advantages and its challenges in doing so. Through a constructivist lens, this paper attempts to unravel Sabah’s historical and social realities, whereby this will be complemented with a Foucauldian discourse analysis to deconstruct Sabah’s dynamic relationship with its colonial British masters and subsequently with the federal government of Malaysia. This is placed in the backdrop of Sabah’s many counterparts in the region as a “peripheral territory”, which had similar pre- and post-colonial era experiences which resulted in the imposition of significant challenges from the lack of right to self-determination to form an identity, lack of formal governing system structure, and in the present day, the lack of autonomy that Sabah has been so long fighting for.
Beyond Religious Fundamentalism: Multidimensional Poverty and Boko Haram’s Appeal Among Northern Nigerian Youths
Authors: C. Njoku Ekele , Singh Jatswan
Published: April 2022

More than a decade into the self-proclaimed Jama'atu Ahlis Sunna Lidda'awati Wal-Jihad’s (Boko Haram) campaign of terror against Nigeria, local and international observers have struggled to explain the raison d'être of the emergence of the extremist group. While most scholars and researchers downplay some contextual factors in Nigeria and trace the source of the unrest to religious fundamentalism in northern Nigeria, this article argues that radicalisation and terrorists acts of the Boko Haram transcend religious fundamentalism and thus, should be seen as a product of an interplay between multidimensional poverty and failure of the Nigerian state to meet its statutory obligations to the people. It further demonstrates that widespread disenchantment and local grievances account for the Boko Haram’s success in attracting significant local support in northern Nigeria. Finally, the article concludes that since it is firmly rooted in northern Nigeria’s peculiar socio-economic environment, the unrest can only be quelled through a concerted effort to alter deep-rooted poverty ravaging the region.
A Rapid Reaction Force for the United Nations: Middle Powers, Human Security, and the Multinational Standby High Readiness Brigade (SHIRBRIG)
Authors: Saclag Daryll Edisonn
Published: April 2022

Contemporary threats to human security have prompted middle powers to call again for the establishment of a rapid reaction force even as they failed to implement the Multinational Standby High Readiness Brigade (SHIRBRIG) over a decade ago. Despite this failure, much of what has been written on middle powers simply assumed that they successfully contributed to human security. Previous studies on rapid reaction force and SHIRBRIG also lacked a theoretical examination - merely identifying lessons learned and offering policy recommendations. Utilising Ronald M. Behringer’s conceptualisation of middle power theory which posits that middle powers use the concept of human security to design instruments that address contemporary security challenges, this article attempts to bridge the gaps in the literature by arguing that middle powers were only successful in creating a rapid reaction force, but not in providing the material capabilities to implement it. Ultimately, the concept of human security was not enough to make middle powers commit vital resources to SHIRBRIG.

Published: April 2022

We have designed Ti3AlB2 and two new layered ordered double-transition
metals MAX compound Ti2ZrAlB2 based on the structure of Ti3AlC2. By
first-principles calculations with density functional theory, their
structure, phase stability, elastic properties, electronic properties
and thermal properties have been further investigated. Results show that
they are all energetic, thermodynamically and mechanically stable. The
bulk modulus, shear modulus, Young’s modulus, Poisson’s ratio and Debye
temperature were computed to discuss their elastic and thermal
properties. Results show that they are all good ductile materials with
high melting points. Density of states and electron localization
function of these three phases were presented to research the chemical
bonds and explore the reason limiting their melting points.

Published: April 2022

The impact of parasites on gut microbiota of the host is well
documented, but the role of the relationship between the parasite and
the host in the formation of the microbiota is poorly understood. Using
16S amplicon sequencing and newly developed methodological approaches,
we characterize the gut microbiota of the sympatric pair of whitefish
Coregonus lavaretus complex and the associated microbiota of cestodes
parasitizing their intestine. The essence of the proposed approaches is,
firstly, to use the method of successive washes of the microbiota from
the cestode’s surfaces to analyze the degree of bacterial association to
the tegument of the parasite. Secondly, to use a method combining the
sampling of intestinal content and mucosa with the wash-out procedure
from the mucosa to understand the real structure of the fish gut
microbiota. Our results demonstrate that the trophic diversification of
a sympatric pair of whitefish predetermines a segregation by ecological
niches of their respective microbial communities within their intestine.
Additional environmental niches for settlement of bacteria in the
intestine are formed by the parasitic helminths that caused the
restructuring of the bacterial community in infected fish compared to
those uninfected. Using the desorption method in Ringer’s solution, we
have demonstrated that Proteocephalus sp. cestodes possess their own
microbial community which is put together from “surface” bacteria
received from the host, bacteria which are weakly and strongly
associated with the tegument, and microbiota obtained after removal of
the tegument from the cestodes.

Nonprofit organizations (NPOs) play critical roles as funding sources,
research partners, and disseminators of emerging drug developments in
pediatric cancer, yet the literature offers limited understanding or
guidance of ethical best practices and processes. We conducted a
systematic search for peer reviewed articles, commentaries, newsletters,
and white papers indexed in the PubMed and Web of Science databases to
identify the ethical, legal, and social responsibilities of NPOs to i)
patients/families, ii) researchers, iii) sponsors, and iv) donors when
funding clinical trials. Fifty-four articles met the inclusion criteria.
Minimizing conflicts of interest, ensuring transparent reporting of
trial endpoints, and communicating with families about trial
opportunities emerged as key themes. We identified critical gaps in the
literature related to negotiating research partnerships, setting trial
priorities and establishing best ethical practices in the emerging field
of venture philanthropy. Results informed points to consider for NPOs
when funding pediatric cancer clinical trials going forward.

Objective: To explore the long-term effects of SARS-Cov-2 infection on
the pulmonary function in convalescent COVID-19 patients of 6 to 9
months follow-up in Beijing, China. Methods: 64 cases of COVID-19
patients were recruited for the study, discharged from the Beijing Ditan
Hospital, Capital Medical University for 6 to 9 months. COVID-19
patients were divided into mild, moderate and severe groups. The
pulmonary function tests, the novel coronavirus antibody (IgM and IgG),
chest CT and blood tests were investigated during follow-up. Results:
31.2% (20/64) patients had pulmonary ventilation dysfunction and 35.9%
(23/64) had diffusion dysfunction. In the severe group, 56.50% (13/23)
individuals showed decreased diffusion function. The diffusion
dysfunction of severe group was significant decreased than the moderate
(P=0.021). Among 56 cases, the positive rate of IgG titers was 73.2%
(41/56). The result of chest CT showed 55.4% (31/56) cases in nodules,
44.6% (25/56) in strip-like changes, 37.5% (21/56) in ground glass
shadow. Patients were tended to have ground glass changes in the severe
group, while nodules in the moderate group. Conclusion: For the 6 to 9
months in convalescent COVID-19 patients, 56.50% (13/23) severe
patients had pulmonary diffusion dysfunction. In the convalescent
COVID-19 patients, especially those with severe illness, should have
their pulmonary function tested regularly.

The losses in the power system vary the gap between energy supply and demand. Among these losses, the distribution system has major contributions compared to the transmission system. This paper thoroughly examines the PESCO distribution losses and implements a practical approach that forties in the loss’s minimization. Using the bifurcation and restoration strategies, the PESCO distribution system can be well-organized and an effective system can be designed. The proposed approach also helps in estimating the entailed capital investments and the rate of return over time. Both the HT (High Tension) and LT (Low Tension) distribution systems are considered for observation and the proposed systems are endorsed. Computer-based software, such as ELR (Energy Loss Reduction) and CADPAW (Computer-Aided Distribution Planning Work) is exploited to measure the results of both the proposed and existing system. After the restoration of a particular system, recommendations are concluded. The proposed approach applies to any existing power system.

Published: April 2022

Introduction. Severe acute respiratory syndrome coronavirus 2
infection-induced coagulopathy may be the underlying cause of acute limb
ischemia, a sudden decrease in limb perfusion. The aim of this study was to
present a case series of acute limb ischemia associated with severe acute
respiratory syndrome coronavirus 2 infection. Material and Methods. This
unicentric, observational cohort study evaluated the incidence, risk
factors, clinical, laboratory and radiological findings, problems in
diagnosis, treatment and outcome of patients with severe acute respiratory
syndrome coronavirus 2 infection-induced acute limb ischemia. Results. The
study included 14 patients with a diagnosis of severe acute respiratory
syndrome coronavirus 2 infection-induced acute limb ischemia in a 20-month
period. The majority of patients were male (78.6%), with a mean age of 67
years, body mass index > 30, and typical cardiovascular risk factors. Only
64.3% of acute limb ischemia patients with coronavirus disease 2019
underwent attempts of limb salvage; 14.3% required primary amputation; 21.4%
were treated with systemic anticoagulant therapy alone. The mortality rate
was high (42.9%). Revascularization was successful in 7 (50%) patients with
acute limb ischemia. The overall amputation rate was 28.6%. Conclusion. The
high incidence of acute limb ischemia associated with severe acute
respiratory syndrome coronavirus 2 infection, even with thromboprophylaxis,
high mortality rates and poor limb salvage outcomes, encourage clinicians to
apply individually tailored diagnostic and therapeutic approaches. Prolonged
systemic use of heparin may improve the effectiveness of surgical treatment,
limb salvage, and overall survival.
Optical coherence tomography analysis of eyes in patients with chronic chiasmal compression: A case report
Authors: Grkovic Desanka , Barisic Sava , Davidovic Sofija , Brunet Stefan , Pavin Svetlana
Published: April 2022

Introduction. Olfactory groove meningiomas cause progressive compression of
the frontal lobes with posterior projection towards the sella turcica. If
large enough, these tumors may cause optic nerve compression and optic
chiasm. The aim of this study was to determine whether optical coherence
tomography, as a method that objectively measures the thickness of retinal
nerve fiber layer and retinal ganglion cell complex thickness, provides a
realistic assessment of the postoperative visual outcome in chronic chiasmal
compression caused by olfactory groove meningioma. Case Report. A
55-year-old woman presented with an eight month history of malaise,
weakness, frontal headaches, anosmia, and blurred vision in both eyes.
Magnetic resonance imaging of the endocranium revealed a large olfactory
groove meningioma extending into the prechiasmal portion of the optic nerves
and optic chiasm with a marked compressive effect. The mean preoperative
retinal nerve fibre layer thickness was 65 ?m in the right eye and 63 ?m in
the left eye. Ten months after surgery, the mean retinal nerve fibre layer
thickness was 67 ?m in the right eye and 63 ?m in the left eye. The mean
preoperative ganglion cell complex thickness was 57 ?m in the right eye,
while it could not be measured in the left eye due to loss of fixation. Ten
months after surgery, the mean ganglion cell complex thickness was 56 ?m in
the right eye and 48 ?m in the left eye. The obtained values were
significantly lower than the physiologic thickness values. Conclusion.
Retinal nerve fibre layer thickness and ganglion cell complex thickness
measured by optical coherence tomography represent a valid prognostic
indicator of visual outcome and recovery after surgical decompression of the
optic chiasm.

Published: April 2022

?-Tricalcium phosphate/fluorapatite (?-TCP/FAp) mixed powders were prepared
in order to obtain dental root canal filling cements. Different liquids for
cement pastes have been investigated and the most suitable one for obtaining
rheologically optimal pastes was chosen for further analysis. Morphological
changes in the cement materials as a consequence of the formation of
hydroxyapatite (HAp) after the immersion in a simulated body fluid (SBF), an
influence on the cell viability, and final success of the filling were
investigated by field emission scanning electron microscopy. Treatment of
the ?-TCP/FAp mixtures in SBF at 37?C resulted in a complete transformation
of ?-TCP into HAp after 10 days, while the exposure of MRC-5 human and L929
animal fibroblast cells to the cement showed complete absence of
cytotoxicity. The root canal of an extracted tooth was filled with the
?-TCP/FAp cement containing 5 wt.% of FAp and relatively strong adhesion
between the cement and dentine was observed after 48h. The same cement
material was immersed during 10 days in SBF and after that both human and
animal fibroblast cells during in vitro MTT tests showed higher cell
viability compared to the control sample. These findings lead to a
conclusion that the ?-TCP/FAp based cement demonstrates potential for
further development towards dental cement application.

Revisiting monetary policy effectiveness in Turkey using a FAVAR model
Authors: Polat Umurcan
Published: April 2022

This study aims to perform a comparative analysis of the effectiveness of
pass-through of policy rates in Turkey. We explore monetary transmission
with different choices of instruments, i.e., the Turkish Lira Reference
Interest Rate (TRLIBOR rate), BIST overnight rate, and Divisia money, and
under different policy regimes, i.e., inflation targeting and new monetary
policy regimes. We estimate a two-stage FAVAR model to use all of the
available information set and obtain direct responses of
disaggregated/sectorial series for the period 2005:12-2018:4. We extend the
model setting proposed by Bernanke, Boivin, and Eliasz (2005) by considering
the multiple-policy environment in Turkey. Our findings promote arguments
that regard policy rate as a poor indicator of the policy stance in Turkey.

Introduction. Chest pain (CP) diagnostics accuracy remains debatable for both general practitioners (GP) or emergency department (ED) physicians for patients in HEART score (HS) low- and intermediate-risk groups which prompted us to review our electronic database for all patients admitted via our center?s ED during 2014 to 2020 for CP and suspect acute coronary syndrome. Methods. Patients were divided in function of low- or intermediate-risk HS and assessed during a three month follow up for angiogram results, major adverse cardiac events (MACE), lab results and echo parameters. Results. Of 585 patients included, low-risk HS group (21,4%, 36% were women) had significant coronary disease on angiogram in 68%, while for intermediate-risk HS group (78.6%, with 32.6% women) it was for 18.4% of patients (p < 0,0005). Area under the ROC curve of HS in detecting patients with ischemic heart disease as a cause of CP was 0.771 (95% CI: 0.772?0.820) with best cut-off point HS was calculated at 3.5. Sensitivity and specificity were 89.2% and 57.6% respectively. Adjusting for sex, lab results and HS, AUROC curve of this model was 0.828 (95% CI: 0.786?0.869; p < 0,0005) with cut-off of 77.95. Sensitivity and specificity were 84.9% and 68% respectively. In the three-month follow-up post-discharge, there was a significant difference in MACE between groups (low- vs. intermediate-risk HS was 3.4 vs. 16.7% p < 0.05). Conclusion. HS for our CP patients admitted via our ED by GP and ED physicians? referral, provides a quick and reliable prediction of ischemic heart disease and MACE.

The study aimed to observed the 3-D structure of GAPDH protein and identify the GAPDH gene sequences mutation of chicken drumstick meat (Gallus gallus). The sample of chicken meat was randomly taken in four districts in Malang city. In this study, the DNA was isolated from drumstick meat chicken samples, amplified using proper primers, and then sequenced using ABI 3730xl DNA Sequencer. The DNA sequences alignments analyzed by BioEdit software and the control sequence of GAPDH gene was obtained from NCBI GenBank (sequence Gene ID: 374193). Then, the amino acid sequence and 3D structure of GAPDH protein were determined based on the change of nucleotide sequences using Swiss model and PyMol software. The nucleotide sequence of a partially GAPDH gene of drumstick meat chicken from districts two is completely different with a 97 percent similarity level, which found twelve nucleotides’ substitutions mutation between nucleotide base number 354 until 777 and three nucleotides inserted between T753 and G754 nucleotide base. These mutations changed the amino acid sequence and 3D structure of GAPDH protein. This result suggests that the differential drumstick chicken meat GAPDH sequences and 3D structure may induce the change of protein-protein interaction and induction.

Writing is one of the most difficult skills in learning English as a Second Language (ESL) or English Foreign Language (EFL). Many language learners encountered difficulties from the writing process. At the tertiary level, students are required to produce academic essays, which are difficult and may frustrate students. The purpose of this study was to analyze factors contributing to students difficulties in an Academic Writing course based on the students perceptions. This study used a qualitative method. The instruments used were open-ended questionnaires and interview protocol. In this study, all the participants answers were coded and analyzed descriptively. The participants were 22 students who were taking Academic Writing class for repeaters in Semester I, 2018/2019 academic year, in an English Language Education Program, in a university in Central Java, Indonesia. Questionnaire data were coded and classified by the researcher. In conducting the interview, data were audio-recorded and transcribed. Those data were analyzed to answer the research questions in this study. Based on the findings, there were two factors that caused students difficulties in writing academically. The two factors were internal and external. Internal factors consisted of self-motivation, self-confidence, lack of knowledge and feeling of under pressure. External factors consisted of the teachers teaching style, classroom atmosphere, materials, and writing aspects. This research hopefully can help teachers and instructors in developing appropriate teaching techniques in Academic Writing and minimize students' difficulties in Academic Writing.

OBJECTIVE

To compare the outcome of canine pyometra surgeries performed at referral hospitals with those performed at community clinics (outpatient settings), and to evaluate factors that impact outcome.

ANIMALS

133 client-owned dogs with pyometra treated with ovariohysterectomy (OHE) at 2 community clinics or 2 referral hospitals between July 1, 2017, and June 30, 2019.

PROCEDURES

A retrospective electronic medical record search was used to identify eligible cases. Data about patient demographics and clinical characteristics were collected and analyzed for factors that could have impacted outcome.

RESULTS

Eighty-three dogs were treated at referral hospitals; 50 dogs were treated at community clinics. Survival to hospital discharge for all dogs was 97% (129/133) and did not differ between treatment facility type. Dogs treated at both types of facilities were similar in age, body weight, and clinical signs. Median duration between diagnosis and OHE was significantly shorter for dogs treated at referral hospitals (0 day; range, 0 to 0.7 days) versus community clinics (1.0 day; range, 0 to 14.0 days); however, delay was not related to survival to hospital discharge. Duration of hospitalization did not impact survival to hospital discharge nor survival for at least 1 week after surgery.

CLINICAL RELEVANCE

Results indicated that OHE for pyometra in dogs has a good outcome and that, although prompt surgical treatment remains a goal, in cases where limitations to performing surgery exist, a delay until surgery or discharging patients the same day is still associated with a high degree of success.
The multimarket model of the veterinary industry
Authors: Neill Clinton L.
Published: April 2022

Within this article, a graphical discussion of the veterinary industry is constructed and discussed. This viewpoint centers around the 4 main markets that operate in veterinary medicine: the market for veterinary education, the market for veterinarians, the market for animals, and the market for veterinary services. Moreover, how each market within veterinary medicine is interconnected is the important point of the article. The purpose of the article is to provide a mechanism for discussion on how changes in one market will affect other markets. From this view, I argue that the market for veterinary services is completely dependent on the other 3 markets in terms of defining supply, demand, and market equilibrium. The remainder of the article discusses how to use the multimarket graphical model to aid in discussions around policy changes and provides an example. Some concluding remarks about this view on the interconnectedness of markets within the industry are provided. Again, the intended purpose of this viewpoint is to provide a graphical understanding of the multimarket nature of the industry and a way to discuss any proposed changes to a market based on literature that empirically estimates many aspects of these various markets. I highly encourage any proposed changes to the industry be supported by mathematical/statistical modeling, but the graphical model can aid in a conceptual understanding of those same changes.

Authors: Mangasarov Ruslan Anatol'evich
Published: April 2022

The article examines the patterns of the spread of economic crime in the Russian Federation, as well as the law enforcement practice of combating economic and corruption crimes related to the distribution and use of budget funds allocated for the implementation of national projects and federal targeted programs. The increase in embezzlement of budget funds has a negative impact on all aspects of public life: it destabilizes the rule of law, disorganizes public relations, undermines trust in the highest state authorities, as a result of which it has a corrupting effect on the administrative apparatus, leads to budget depletion, etc. In this regard, the priority task is to organize proper control over the distribution and expenditure of budget funds in all areas of the economy. The article provides a theoretical and practical analysis of the essence of criminological, operational-investigative and criminal-legal bases for combating economic and corruption-related crimes related to the distribution and use of budget funds allocated for the implementation of national projects and federal targeted programs. The novelty lies in a number of conclusions formulated in the course of the study. In particular: a) the signs of the crimes under consideration are highlighted; b) the main directions of criminal aspirations in the field of economic activity are identified; c) the methods of committing the theft in question are highlighted, a number of signs are identified that indicate an increasing public danger of economic crime, etc.
