Objective: To reveal the morphological and anatomical structure of the nasopalatine canal (NPC) and analyze its measurements via cone-beam computed tomography (CBCT). Methods: A total of 246 CBCT images were included in the study.) NPC diameter, length, angle, distance from the IF to buccal bone (M1), distance from the NF to buccal bone (M2), and the distance from the middle of the NPC to buccal bone (M3) were measured. Statistical significance was assumed at p < 0.05. Results: There was a significant difference between gender and NPC length, M1 and M3 (p = 0.008, p = 0.019 and p < 0.001, respectively), and between the presence of teeth in the anterior maxilla and M1 (p < 0.001). There was a significant difference between the shape of NPC in the coronal plane and NPC angle (p = 0.012) and between the shape of NPC in the sagittal plane and NF diameter, IF diameter, M1 and the M3 (p < 0.001, p = 0.006, p = 0.031 and p < 0.001, respectively). Conclusion: NPC variations, gender, and the presence of teeth in the anterior maxilla could affect NPC measurements. Physicians planning surgery in the anterior maxilla should pay attention to this situation.

Dentistry is a highly stressful program; stress is associated with xerostomia and periodontal disease. Objective: This study aims to investigate the association of perceived stress, severity of xerostomia, and periodontal status in dental students. Methods: This was a two-phase cross-sectional study of 245 Universiti Sains Malaysia (USM) undergraduate dental students. Phase 1 involved administration of the Perceived Stress Scale (PSS-10) and Summated Xerostomia Inventory (SXI). In phase 2, the Community Periodontal Index (CPI) was performed on 150 students to determine their periodontal status. Results: Mean PSS-10 and SXI scores were 19.6 (SD 5.47) and 7.9 (SD 2.04), respectively. Only 7.3% students had healthy periodontium while 17.3% had gingival bleeding, 65.3% had calculus, 6.7% had shallow pockets, and 3.3% had deep pockets. The association of perceived stress, severity of xerostomia, and periodontal status was not significant. Nevertheless, a significant positive correlation was found between PSS-10 and SXI scores (r = 0.318, p < 0.01). Conclusion: Most USM dental students were affected by some degree of periodontal disease, but it was not associated with perceived stress or severity of xerostomia. Students with higher perceived stress had more severe xerostomia. Information from this study could be utilised by the dental school in planning towards providing a stress-free training environment.

Authors: Sharma Nishesh , Nishant Kumar  , James Jerin , Sonika Kalia  , Joshi Shiwani
Published: September 2023

The micropropagation technique serves as an effective approach for conserving and propagating numerous plant species. Challenges to its success encompass explant selection, media composition, hormone concentration, microbial contamination, incubation conditions, and photoperiod. Beyond these factors, the veracity of tissue culture hinges on successful acclimatization of in vitro regenerated plants to their natural surroundings. Tissue culture-derived plants exhibit characteristic variations like altered nutrition, reduced cuticular wax, non-functional stomata, etc. During transition to natural conditions, a significant portion of micropropagated plants face survival challenges. Studies propose gradual acclimatization processes for smooth adjustment. Ex vitro rooting is advocated for economic, simple, and enhanced survival outcomes. Hydroponics, photoautotrophic acclimatization, and biotization strategies also improve post-transplantation survival. This study evaluates diverse strategies for achieving successful acclimatization of in vitro regenerated plants.

Published: September 2023

To study the characteristics of sugar beet cultivars in transplanting and direct-seeding systems on three different sowing times (March 29, April 8, and April 18), a split plot experiment based on randomized complete blocks in three replications was carried out in Miandoab and Bokan regions, Northwest of Iran in 2016. The results showed that the highest nitrogen content was observed between the two test locations in the Bukan area. Results showed that the low root sodium, alkalinity, and molasses content was recorded for transplanting system. The minimum content of root sodium, nitrogen, and molasses sugar was observed in the plants sown on March 29. The Dorotea cultivar showed the highest root yield, sugar yield, and white sugar yield and the lowest root nitrogen and molasses sugar content compared to Isabella and Ekbatan. The highest white sugar content, coefficient of sugar extraction, sugar yield, root yield, and white sugar yield were recorded in the transplanting system with the sowing time of March 29; however, the highest content of root potassium and sugar content was observed in the transplanting system sown on April 18. The highest root yield was observed in the Dorotea cultivar, with a sowing time of March 29. Among the locations in the cultivar and planting system interaction treatments, the highest sugar content was found in the Bukan area's Dorotea cultivar in the transplanting system. Finally, the highest sugar yield was related to the transplanting system on March 29 in the Bukan area. It can be stated that an early sowing time (March 29), transplanting, and Dorotea variety were identified as the most appropriate treatments to improve the economic traits of sugar beet.

Published: September 2023

Alzheimer’s disease (AD) is a relatively common senile neurodegenerative disease and the main manifestation of senile dementia. In the pathological changes of AD, the asymmetry of the brain also changes. Therefore, finding an early diagnosis method of AD based on asymmetry is the key to the treatment of Alzheimer’s. Magnetic resonance (MR) imaging can quantitatively reflect the structural and functional changes of various tissues in the brain. It has the advantages of non-invasive, high spatial resolution, and non-radiation, and has been widely used in the early diagnosis of AD. In this work, asymmetric images were extracted from multiple brain MR images, and different morphological and texture features were extracted. By establishing a feature selection classification integration model, image features in the image were deeply fused to obtain higher and more stable recognition results than before. By filtering image samples, the corresponding sample feature matrix was obtained. Support vector machine was used for classification, and its classification accuracy had improved significantly compared with that before selection. In the experimental data of normal control group and AD group, the accuracy, sensitivity, and specificity of the feature selection algorithm were 93.34, 90.69, and 95.87%, respectively. In the normal control group and the mild cognitive impairment group, the accuracy, sensitivity, and specificity of the feature selection algorithm in this work were 85.31, 79.68, and 88.54%, respectively. On the whole, the classification accuracy of the feature selection algorithm in this work was much higher than that of other items. In addition, from the classification ability and distribution of asymmetric features, it can be seen that this asymmetric feature had a more significant consistent diagnostic role in clinical practice.

Authors: Gobioff Samantha , Plakogiannis Michael , Grünebaum Amos
Published: September 2023

Objectives

With increasing rates of cesarean delivery across the United States, a trial of labor after cesarean (TOLAC) is a reasonable alternative for qualified candidates. Although Müllerian anomalies are associated with a variety of adverse pregnancy outcomes, there is little existing data regarding TOLAC in these patients. We present a case of a patient with a didelphys uterus who achieved a successful vaginal birth after cesarean section (VBAC) in the setting of labor augmentation.

Case presentation

Our patient is a 32-year-old G4P1021 (Gravida 4 Para 1,021–1 term delivery, 0 preterm deliveries, 2 abortions, 1 living offspring) who presented at 8 weeks of gestation with a known history of a didelphys uterus. Her obstetrical history was significant for a prior low-transverse cesarean section at term. All four of her pregnancies were located in the right uterine horn. At 39 weeks 3 days of gestation she presented in early labor and requested a TOLAC. She received an epidural, a cervical ripening balloon was placed, and she was started on pitocin. She pushed to deliver a viable infant. The patient’s postpartum course was uncomplicated, and she was discharged home on postpartum day two.

Conclusions

Müllerian anomalies are associated with several poor pregnancy outcomes including increased rates of PPROM, preterm delivery, FGR, and malpresentation necessitating a cesarean section. Our patient required augmentation of her labor but was ultimately able to achieve a successful VBAC with a healthy neonate. She represents an understudied population of patients with uterine anomalies who not only can have favorable pregnancy outcomes but may even be able to safely achieve a VBAC.

Authors: Liu Xin , Chang Yingxian , Zhang Hao , Zhang Fangzhe , Sun Lili
Published: September 2023

The power system operation and control data are from a wide range of sources. The relevant data acquisition equipment is disturbed by the complex electromagnetic environment on the power system operation and control lines, resulting in data errors and affecting the application and analysis of data. Therefore, a power data integrity verification method based on chameleon authentication tree algorithm and missing trend value is proposed. Get 2D data from different sensors and place it in the space environment. After data conversion, convert heterogeneous data into the same structure, expand the scope of power data acquisition, and conduct power system operation and control node layout and integrity data acquisition; The chameleon authentication tree algorithm is used to deal with the heterogeneous information of the power data, and the true value of the data is determined in the heterogeneous conflict of the power data at the same site; Query the integrity data based on the power system operation and control positioning node, creatively calculate the missing trend value of power data, evaluate the importance of data integrity, obtain the priority of power data integrity verification, and complete the integrity verification of power data. The experimental results show that the optimal clustering number is 9.05, the distribution coefficient is 16.30, the absolute error of validity analysis is 2.80, all test indicators are close to the preset standard, and the trend of the validation curve is close to the trend of the set demand covariance curve. Ensuring the integrity of power data and determining the important indicators of power lines are more conducive to the safe and stable operation of the power data center.

Preparation and properties of dynamic crosslinked styrene butadiene rubber
Authors: Lu Hui , Wang Pingyin , Tian Yaozhu , Luo Zhu
Published: September 2023

As the second largest synthetic rubber after styrene butadiene rubber, cis-butadiene rubber (BR) is one of the important raw materials for automobile tires and cold-resistant products. Herein, a traditional rubber preparation process was used to introduce dynamic reversible bonds into BR based on an “imitative” click reaction. Compared with traditional complex self-healing techniques, this method is undoubtedly simpler and more efficient. Dynamic reversible bonds are able to break and recombine under the stimulation of external conditions, which endow rubber with self-healing properties. We use the small biological molecule lipoic acid (LA) as a cross-linking agent and cross-link LA and BR through mechanical compounding and hot press vulcanization to obtain self-healing butadiene rubber (BLA). In addition, BLA-(Zn2+) was further prepared by introducing Zn2+ to form metal-oxygen coordination bonds with carboxyl groups. And systematically studied the effect of Zn2+ on the mechanical properties and self-healing properties of cross-linked BR. Through the combined action of disulfide bonds, hydrogen bonds and Zn2+-O coordination bonds, BLA-(Zn2+) has better properties than BLA, the tensile strength can reach 3.76 MPa, and the repair efficiency is about 82 %. This simple preparation process is certainly more cost effective.

Published: September 2023

Proteins are the building blocks of all living things. Protein function must be ascertained if the molecular mechanism of life is to be understood. While CNN is good at capturing short-term relationships, GRU and LSTM can capture long-term dependencies. A hybrid approach that combines the complementary benefits of these deep-learning models motivates our work. Protein Language models, which use attention networks to gather meaningful data and build representations for proteins, have seen tremendous success in recent years processing the protein sequences. In this paper, we propose a hybrid CNN + BiGRU – Attention based model with protein language model embedding that effectively combines the output of CNN with the output of BiGRU-Attention for predicting protein functions. We evaluated the performance of our proposed hybrid model on human and yeast datasets. The proposed hybrid model improves the Fmax value over the state-of-the-art model SDN2GO for the cellular component prediction task by 1.9 %, for the molecular function prediction task by 3.8 % and for the biological process prediction task by 0.6 % for human dataset and for yeast dataset the cellular component prediction task by 2.4 %, for the molecular function prediction task by 5.2 % and for the biological process prediction task by 1.2 %.

Authors: Zhou Yue , Gao Haiyan , Xu Hujun , Li Ying , Zhang Hongqiang , Lu Zirui
Published: September 2023

A series of novel gemini surfactants (m-E2Ph-m) with ester groups and a benzene ring as rigid spacer were synthesized and characterized by IR, 1H NMR and Mass spectrometry. The effect of hydrophobic chain length on the surface properties and aggregation behavior of the gemini surfactants were investigated by the measurements of surface tension, electrical conductivity, fluorescence. The critical micelle concentration (CMC) of these surfactants decreases with increasing alkyl chain length. The thermodynamic parameters exhibited that the micellization was a spontaneous and exothermic process in environment. The micellization process became more beneficial with the increase of alkyl chain length and the decrease of temperature.

Authors: Somuncu Elif , Mamedov Bahtiyar A.
Published: September 2023

In this paper, a new theoretical approach is suggested for the numerical calculation algorithm of the fourth virial coefficient and its components with the Kihara potential. For the first time, this study reports the results of the fourth virial coefficient over the Kihara potential. The proposed method can be used to calculate the thermodynamics properties of gases with developed correctness. The method is tested for some molecules and as an example of application, the proposed method has been performed for gases of C3H8 and SF6. The obtained calculation results have been compared with the theoretical and experimental data and the results have been found to be consistent with the literature data. It can be seen from the application that the calculation of the fourth virial coefficient with the Kihara potential can provide important results in the calculation of the thermophysical properties of other real systems.

Published: September 2023

Inadequate wastewater treatment infrastructure is a major environmental and public health concern worldwide. Industrial effluents containing organic pollutants such as dyes constitute a severe challenge due to their toxicity. Malachite green (MG) and methylene blue (MB) are two organic dyes that are widely used in textiles but also damage the environment. Herein, we report the fabrication of bismuth ferrite-coated nickel/nickel oxide foam (BFCNF) heterojunction photocatalyst via the dip-coating approach. The point of zero charge and the estimated surface area of BFCNF was observed to be 7.5, and 213.19  m2 g−1, respectively. Energy dispersive X-ray (EDX) spectra revealed the presence of Ni, O, Bi, and Fe elements in the BFCNF. The scanning electron microscopy (SEM) analysis revealed that BFCNF has a granular coarse surface morphology. The XRD anslysis showed that the average-crystallite size for Ni/NiO, BFO, and BFCNF was found to be 28, 1.00, and 1.00 nm, respectively. The catalyst revealed outstanding performance while degrading 97 % of MG dye at pH 6, and 98 % MB dye at pH 5, under visible light irradiation of 20 min. The chemical oxygen demand (COD) studies were also performed for both of the dyes. Notably, a negligible COD was observed for both of the dyes after 80 min. In a real industrial wastewater treatment study, the catalyst almost degraded 99 % of both dyes. Further, the catalyst revealed excellent stability during four and seven consecutive recycles tests for MB and MG dyes, respectively. The degradation process follows pseudo-first-order kinetics with correlation coefficients (regression analysis, R
2) of 0.949 and 0.974 for MG and MB, respectively. To the best of our knowledge, this is the first report on utilization of bismuth ferrite-coated nickel/nickel oxide foam based heterojunction photocatalyst. This work will trigger the development of highly efficient catalysts for efficient wastewater treatment.

Published: September 2023

Objective:

The objective of the present study was to determine the prevalence, antimicrobial resistance, virulence profiles, and molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) obtained from ready-to-eat (RTE) foods in China.

Methods:

Two hundred seventy-six RTE food-associated S. aureus isolates were collected from 25 provinces across China in 2018, then characterized by antimicrobial susceptibility testing, virulence factors detecting, multilocus sequence typing (MLST), spa typing, SCCmec typing and pulsed-field gel electrophoresis (PFGE).

Results:

Two hundred fifty isolates (90.6%) were resistant to at least one antimicrobial agent; 73 (26.4%) isolates were multi-drug resistant (MDR). Thirty MRSA isolates were identified, among which nine toxin genes (sea, seb, sec, sed, seh, selk, sell, selq, and tsst-1) were detected. Sixty percent (18/30) of the MRSA isolates harbored multiple toxin genes. Four virulence gene patterns were identified, with seb-selk-selq (30/30) being the most common pattern. Thirteen sequence types, as well as 13 spa and 4 SCCmec types were found among 30 MRSA isolates. The most prevalent MRSA lineages were CC59-t437-SCCmecIV/V (23.3% [7/30]), CC398-t011-SCCmecV (23.3% [7/30]), and CC1-t114-SCCmecIV (16.7% [5/30]).

Conclusions:

Our findings highlight the importance for the identification of prevalent clones, assessment of drug-resistance and virulence, and formulation of food safety measures for public health.

Published: September 2023

The research proposes a methodical approach to the construction of complex organizational and technological systems, which implements the principle of weakening overdeveloped or weakening underdeveloped components at certain intervals of development. Based on the use of morphological synthesis in order to build a normative forecast of organizational and technological system in high-tech production requires the involvement of a wide range of specialists to solve the difficult problem of substantiating models of system components, as well as expert assessment at the stage of weakening areas of insufficient or excessive development of system components. The network state of the system is considered as the states of component balance, according to which it is still possible to ensure the fulfillment of the main task and components of the system for the maximum possible development. In this situation, both the conditions of external balance and the conditions of internal balance of the system are met, so that its components receive the maximum possible development. The state of maximum development of the components of the system in the conditions of allocation of fixed appropriations actually means ensuring the resource balance, i.e. compliance with the costs necessary for the development of the system in accordance with the appropriations provided.

O jogo é entendido enquanto um fenômeno complexo, em que a ação do jogador se caracteriza pela eticidade, uma vez que, além de expressar sua subjetividade, visa à boa vida (no caso do jogo, o prazer e a vitória). Assim, o caráter ético da ação do jogador se constitui em um ambiente de jogo, local que a imprevisibilidade, a dinâmica e as novas organizações estão presentes. Dessa maneira, faz parte da função do jogador compreender o ambiente em que ele se encontra, ou seja, entender como as organizações do jogo ocorrem. De modo semelhante, o conceito chamado de “absurdo”, criado por Albert Camus, filósofo franco-argelino, assemelha-se a essa demanda do entendimento do meio em que se vive, ao exaltar a tomada de consciência. Como consequência, segundo ele, o único movimento possível, posterior à compreensão do absurdo é a revolta, ação pautada na expressão do sujeito, com vistas à justiça, à coletividade e à unidade, baseando-se em limites que não devem ser ultrapassados. A partir disso, portanto, pensa-se na possibilidade de entender o jogador enquanto um homem revoltado no jogo, buscando, dada a identificação do meio em que se está, o sucesso de sua equipe, através de suas ações.
La relación entre la teoría de la justicia de Hume y Rousseau
Authors: Lozano-Vargas Humberto , Botero-Bernal Andrés
Published: September 2023

El presente artículo consta de tres partes. La primera consiste en analizar el concepto de justicia dentro del pensamiento de David Hume en las obras Tratado de la naturaleza humana e Investigación sobre los principios de la moral. La segunda aplica el el proceso anterior pero a las obras de Jean Rousseau Contrato Social y Discurso sobre el origen de la desigualdad entre los hombres. La tercera establece que las concepciones sobre la justicia, tanto las del escocés como las del ginebrino, poseen contextos y sentidos distintos pero que, en realidad, son posturas que tienen algunas similitudes en lo que respecta al fundamento de la propiedad.
Discontinuidad y dispositivo:
Authors: Moreno García Manuel Eduardo
Published: September 2023

El presente artículo reconoce que las dos grandes metodologías de Foucault (la arqueología y la genealogía) surgieron en dos momentos diferentes de su enfoque metodológico, y argumenta que a partir de la década del setenta se desarrolla el concepto de dispositivo en el filósofo debido a una discontinuidad en su investigación. Se sostiene que este problema surgió a raíz de una serie de situaciones: el descubrimiento de un nuevo problema de investigación y su relación con la ocurrencia de una coyuntura sociopolítica especifica (fracaso de las movilizaciones sociales del mayo francés en 1968). Lo anterior llevó a Foucault a plantear la pregunta por ¿cómo se ejerce el poder y cuál es su relación con el saber?, en lugar del antiguo interrogante sobre ¿qué es el poder? Esta transformación de la pregunta resultó fundamental en Foucault, ya que le permite concluir que todo dispositivo presupone la existencia de un poder y que todo poder se ejerce mediante la utilización de un saber. El artículo se cierra con una referencia a Jurgen Habermas, autor que precisa la crisis que generó en Foucault el fracaso de las movilizaciones sociales ocurridas durante el denominado mayo francés.  El presente trabajo se elaboró a partir de un método de investigación cualitativa y una técnica de rastreo bibliográfico.
What Causes Foreign Language Speaking Anxiety?
Authors: Qu Liaojian
Published: September 2023

As a result of the development of humanistic psychology in the 1960s, there has been a growing recognition that affective factors can significantly impact the outcomes of education (Lu, 2001). Affective factors in language learning, particularly in second language acquisition, have been reckoned as non-cognitive factors and along with cognitive factors, have sparked substantial attention among academics. Affective variables that may influence foreign language acquisition include a variety of emotions and feelings arising in foreign language classroom such as anxiety, fear, embarrassment, or sense of inferiority. Among them, second language anxiety has long been a popular topic in foreign language instruction research.
Life Education: Reshaping Education for the Sake of Life
Authors: Yao Jijun
Published: September 2023

Life is the starting point as well as the primary aim of all educative activities. The essence of education is to create conditions to support the development of individual life, as Montessori (2004) famously said that the purpose of education is to foster the healthy development of force of life in children, and that education is everything that has the potential to boost their vitality. Successful education allows students to grow in an autonomy-supportive environment and learn to appreciate, respect, and treasure life while acquiring academic knowledge. This is the fundamental responsibility of education (Lansdown, 2005). Pointless are the seemingly great accomplishments of the individual who has no idea of meaning in life; likewise, any education that fails to assure the healthy development of individual life is ineffective, no matter how advanced it appears.
Foreign Language Speaking Anxiety and its Link to Speaking Self-Efficacy, Fear of Negative Evaluation, Self-Perceived Proficiency and Gender
Authors: Okyar Hatice
Published: September 2023

This research study aimed to explore the speaking anxiety of Turkish learners of English as a foreign language (EFL) and its relation to EFL speaking self-efficacy, fear of negative evaluation (FNE), self-perceived English speaking proficiency, and gender. 293 (132 females, 161 males) university-level EFL students completed the EFL speaking anxiety scale, EFL speaking self-efficacy scale, and FNE scale. Four main findings were obtained as a result of the statistical analyses: (i) students’ speaking anxiety had a negative relationship with both self-perceived oral English proficiency and speaking self-efficacy, (ii) a positive relationship was determined between FNE and speaking anxiety, (iii) EFL speaking anxiety was found to be lower in boys than in girls, and (iv) speaking self-efficacy, FNE, and self-perceived oral proficiency were identified as meaningful predictors of students’ EFL speaking anxiety. In light of these findings, the study offers some pedagogical implications.
Ensuring the confection strength of adhesives based on SBS copolymers of various topologies
Authors: Nebratenko D Yu
Published: September 2023

This work is devoted to the improvement of a new building material for the road market - connecting bitumen-polymer tapes. The conditions for the use of such tapes have recently been significantly expanded both as a result of the harsh operating temperature conditions of the coating, and due to the need for road construction work at unsatisfactory temperature and humidity. The study attempts to assess the feasibility of using some brands of styrene-butadiene thermoplastic elastomers as a polymer base of adhesives to provide short-term increased strength of fastening of connecting bitumen-polymer tapes to the side surfaces of the crushed stone base for the period before laying a hot asphalt concrete mixture and forming a monolithic asphalt concrete coating in the seam area. The work on the study of a new type of material was hampered by the lack of appropriate technical standards for checking the quality of bitumen-polymer tapes for delamination and separation. Therefore, a high-hardness rubber compound based on styrene-butadiene rubber was chosen as a model solution. The data obtained confirmed the assumption about the effectiveness of various brands of SBS polymers to ensure the confectionery resistance of the base. The established dependencies were distributed and confirmed for highly porous concrete and embedded parts of metal fences.
Low-cost debris deorbiting plus planetary protection
Authors: J Schubert Peter
Published: September 2023

Space debris can be deorbited by a coating of volatile material that evaporates in sunlight. Consider a roque CubeSat that gets splashed with black gel while on the night side of its orbit. As it emerges into the rays of the Sun, kinetic evaporation provides a retro force relative to the orbital velocity, causing speed to diminish. At midpoint of orbital dayside, the net force is downward, towards the Earth’s atmosphere, where drag increases. If sufficient gel remains unevaporated during the transition back to nightside, there could be acceleration, but the dose of gel is limited to avoid this. Gel balls can be delivered from a standoff distance such that orbital matching need not be perfect, saving time and fuel for the debris-hunter. Larger chunks of debris can be shot with multiple gel balls designed that rupture and wet the surface, similar to a paint marking capsule (“paintball”), to provide more retroforce. For very large objects, such as earth orbit-crossing asteroids, judicious application of volatile material can provide a net force away from the Sun, altering the trajectory sufficiently to avoid impact. This work considers the velocity distribution in a liquid assuming the Maxwell-Boltzmann equation, the vapor pressure using the Clausius-Clapeyron equation, and the evaporative flux using the explicit Schrage equation to model vapor kinetics from the Knudsen layer under direct solar irradiation. A concept of operations for a notional debris-hunter satellite design allows an estimate of debris mass that can be deorbited in a given period of time. From this, and an estimate of launch mass, the number and mass of space junk that can be removed from a higher low-earth orbit (LEO) can be calculated. These expenses are sufficiently smaller than the consequence of a Kessler syndrome to compel spacefaring nations to implement this proactive approach without delay.
County lines and the impact of police response: a study of Norfolk compared with East Anglia and the nation (England and wales)
Authors: O’Hagan Andrew , Hamis Kiara M
Published: September 2023

In the region of 88% of all police forces in England and Wales have reported the operation of lines in their area. Norfolk is one of the highest ranked areas for association with county lines. The police force and government have subsequently input a number of operations, projects, and funding to tackle the issue. This study aims to utilise national data on drug offences within the UK. It will use independent studies to create an overview of county lines activity within Norfolk and East Anglia and the impact that police response has had on the issue. Graphical representation of the drug-related arrests identifies that there is no visible difference between Norfolk and other East Anglian counties (except Hertfordshire) or the Nation (England and Wales). Furthermore, the modern slavery statistics show that the Covid-19 lockdown caused an increase in the number of referrals to social services in relation to county lines. Case studies and local statistics show that there has been an impact within Norfolk and the police and government response is reducing the number of high harm lines operating within the county. The next step for the police is to collaborate with other services to work on a holistic approach to tackling the heart of the issue. The significance of this work is to highlight county lines in individual areas and whether more could be done to tackle the problem across the UK. Further study of more local areas should be carried out for comparison and to grasp an understanding of the enormity of the situation.
