Published: January 2022

This study aims to analyze the use of Incinerated Bio-Medical Waste Ash (IBWA) in reinforced concrete structural member with ground granulated blast furnace slag (GGBS) as an alternate building ingredient instead of cement. Biomedical waste was produced from various medical resources such as hospitals, medical institutes and research centres. GGBS is the waste generated from the steel plant. The climate is now being affected by the release of CO2 (global warming) from the Portland cement industries. Therefore, greater attention must be paid to study efforts to use geopolymer concrete. Geopolymer is a novel inorganic eco-friendly binding agent derived from an alkaline solution that stimulates aluminosilicate source material (GGBS, Rice Husk Ash, Quartz Powder, metakaolin, fly ash and Silica Fume). In this research, laboratory tests for Reinforced Geopolymer Concrete (RGPC) beams (deflection, ductility factor, flexural strength and toughness index) and columns (load-carrying ability, stress-strain behaviour and load-deflection behaviour) were conducted for three types of proportions using [30% IBWA – 70% GGBS Geopolymer concrete, GGBS Geopolymer concrete and Reinforced Cement Concrete. The experimental findings revealed that the performance of reinforced 30% IBWA – 70% GGBS geo-polymer beams and columns worked more effectively than reinforced cement concrete beams and columns.

Published: January 2022

Garlic is a globally used spice due to its pungent taste and a fishy deodorant and digestive stimulator. Owing to the widespread use of garlic in both Oriental and Western medicine, further investigations on garlic extracts might carry important implications in the industry. In this study, we conducted extraction of garlic extraction by two conventional methods and an ultrasonic assisted method. The processes were optimized with respect to various quality parameters including polyphenol, flavonoid content, and antioxidant activity. The results showed that extracting garlic under the ultrasonic support will show higher efficiency than the non-ultrasonic extraction. The optimal extraction parameters are: 70% ethanol solvent, 10/1 solvent / material ratio, 40 °C temperature and 40 minutes time.

Published: January 2022

The current investigation aims to synthesize MgFe2O4 magnetic nanoparticle and measure the thermal conductivity of MgFe2O4 ferrofluid. Prepared MgFe2O4 nanoparticle's structural characterization, the concentration of constituents, and surface morphology were analyzed using XRD, EDAX, and TEM respectively. This study also analyses the influence of magnetic flux on the thermal conductivity of MgFe2O4/ EG: H2O (60:40) based ferrofluids formed by the two-step method. Thermal conductivity of ferrofluid measured at different volume fractions (ranging from 0.01% to 0.20%) show that thermal conductivity augmented with an escalation in volume fraction and the highest enhancement of 10.32% was reached at 0.20% volume fraction. Results indicate that the applied magnetic flux improves the thermal conductivity of ferrofluid from 10.32% to 14.75% at 0.20% volume fraction and 350 Gauss Magnetic flux.

Published: January 2022

An electricity board acquires several transformers from a manufacturer in a belief that their advertised lifetime of the transformer thus purchased is true. However, they don’t take in the case of negligence in maintenance of transformer, which is a strenuous job. The advertised thirty-year lifetime is reduced to a mere two-year lifetime, mainly because of the degradation of the insulation medium (Transformer oil), thus increasing losses in the transformer and decreasing its efficiency. The degradation of transformer oil leads to safety hazards like transformer bursting, consequently forcing the electricity board to replace the transformer, thus incurring huge amount of costs. This is the most relatable problem faced by the electricity board in every state. This research work aims at listing out various properties of transformer oil and ascertaining major impurities in a transformer oil by testing it using various techniques. The proposed work deals with long term observation and analysis of transformer oil to determine its degradation rate. Breakdown voltage, Moisture content, Resistivity, Acidity, Furan Analysis and Dissolved Gas Analysis were done using Mushroom electrodes, Karl Fischer Titration test, Tan delta test, Potassium Hydroxide Titration, High performance liquid chromatography, and dissolved gas analyzer respectively. The results reveal that, deviation of Breakdown Voltage, Moisture content, and 2-Furaldehyde (1197ppb) from the permissible limits can indicate the aging of the transformer.

Published: January 2022

Purpose: The availability of fresh Citrus fruits is limited by their susceptibility to invasion by microbial pathogens which leads to cause serious postharvest losses. The present study was carried out to isolate and morphologically identify postharvest fungal associations from selected Citrus fruit species (C. sinensis, C. limon, C. crenatifolia and C. medica) and to confirm their identity by molecular characterization. Research method: Postharvest fungal associations of selected Citrus fruit species were isolated, and identification was done based on morphological characteristics. Confirmation of fungal associations was done through phylogenetic analysis of newly generated ITS sequencing data. Further, frequency of occurrence of each fungal isolate was calculated in three different districts in Sri Lanka. Findings: From the morphological and molecular identification, Collectrichum fructicola, Collectrichum gloeosporioides, Lasiodiplodia theobromae, Aspergillus niger and Pestalotiopsis sp. were recorded from C. sinensis. Neofusicoccum parvum, Collectrichum gigasporium and Aspergillus clavatus were isolated from C. crenatifolia. Further, Lasiodiplodia theobromae and L. pseudotheobromae were the only fungal association isolated from C. limon and C. medica fruit species, respectively. It is worthwhile noting that this is the first report of association of the C. gigasporium and Pestalotiopsis sp. from Citrus fruits in Sri Lanka. Research limitations: Since this research was mainly focused on the isolation and identification of the potential fungal associations, pathogenicity evaluation could not be carried out. Originality/Value: Findings of potential disease causative agents in citrus will be valuable for agriculture sector, to adopt and practice effective strategies to minimize postharvest losses of citrus fruits.

Published: January 2022

Purpose: Spodoptera frugiperda is a recently introduced alien invasive pest in Sri Lanka which can be a threat to many crops including maize, paddy, sugarcane, green gram, vegetables and fruits. Identification of this pest at the egg stage is important in controlling the larval stages of development. Therefore, the present study was conducted to record the morphological and morphometric characters of the eggs of S. frugiperda for accurate identification at the initial stage. Research Method: Thirty-six egg masses of laboratory reared S. frugiperda were observed and measured under a dissecting microscope. Position of the egg clusters on plant, characters of the egg cluster and eggs, number of eggs per egg cluster and diameter of eggs were recorded. Findings: The study revealed that the female S. frugiperda laid eggs mainly on the underside of the leaf blade as clusters containing 9 – 200 (73 ± 7) eggs. Eggs were mostly arranged as single layers and when arranged in multiple layers, the bottom layer had a larger number of eggs than the upper layers. Most of the egg clusters were irregular in shape and some were covered with hairs. Eggs were spherical and initially creamy white in colour that gradually turned light grey when about to hatch. The diameter of eggs ranged from 0.38 mm to 0.55 mm. Originality/ Value: The study documents the morphological and morphometric characters of S. frugiperda eggs for accurate identification. Early detection of the insect pest facilitates the management of their population before causing an economic damage.
Designs for Reliability and Failure Mode Prevention of Electrical Feedthroughs in Integrated Downhole Logging Tools

Published: January 2022

To enable an electrical feedthrough integrated down-hole logging tool to maintain high reliability during its logging service in any hostile wellbores, it is critical to apply some guidelines for the electrical feedthrough designs. This paper introduces a safety factor-based design guideline to ensure an integrated electrical feedthrough has sufficient compression or thermomechanical stress amplitude in the stress well against potential logging failures. It is preferred to have a safety actor of 1.5–2.0 for an electrical feedthrough at lowest temperature, such as −60°C, and a safety actor of 2.5–5.0 at operating temperature range of 200–260°C. Moreover, the designed ambient pressure capability should be 1.5–2.0 times higher than the maximum downhole pressure, such as 25,000–30,000 PSI. To validate this thermomechanical stress model, several electrical feedthrough prototypes have been tested under simulated 200–260°C and 31,000–34,000 PSI downhole conditions. The observed testing data have demonstrated that there is a maximum allowable operating pressure for an electrical feedthrough operating at a specific downhole temperature. It is clearly demonstrated that an electrical feed-through may operate up to 60,000 PSI at ambient temperature in a real-life application, but it may actually operate up to 30,000–35,000 PSI at 200–260°C downhole temperatures.

Published: January 2022

Objectives：MiR-140 and DNAJC3-AS1 have been proven to play critical roles in cancer biology, while their participations in acute myeloid leukemia (AML) are unclear. This study aimed to explore the role of miR-140 and DNAJC3-AS1 in AML.

Methods：Analysis of the expression of DNAJC3-AS1 and miR-140 was done with RT-qPCR. The role of DNAJC3-AS1 and miR-140 in the expression of each other was explored with overexpression assay. The direct interaction between DNAJC3-AS1 and miR-140 was analyzed with RNA pull-down assay. The subcellular location of DNAJC3-AS1 was explored with cellular subcellular fractionation assay. Cell proliferation analysis was done with BrdU assay.

Results：AML patients showed increased expression of DNAJC3-AS1 and decreased expression of miR-140. DNAJC3-AS1 was detected in both nuclear and cytoplasm samples, and a direct interaction between DNAJC3-AS1 and miR-140 was observed.  

Discussion：Reduced expression of DNAJC3-AS1 was observed after miR-140 overexpression in AML cells. DNAJC3-AS1 increased cell proliferation and inhibited the role of miR-140 in suppressing cell proliferation.

Conclusion：In conclusion, miR-140 may target DNAJC3-AS1 to suppress cell proliferation in AML.

hematopoietic clonal neoplasms. MDS occurs mainly in elderly patients. KMT2A rearrangements (KMT2A-r) are rare in MDS, so little is known about their prognostic value. The present study describes the clinical characteristics of a young adult patient diagnosed with MDS-EB-2, presenting the t(11;16)(q23;q24). The Decitabine treatment was initiated since no matching donor was found. The patient showed improved anemia and thrombocytopenia. However, he still had severe neutropenia and clonal chromosomal alteration.   Two months after the fifth cycle of Decitabine, the patient presented a worsening of the clinical parameters with increased blast and evolution to AML. He was treated with intensification chemotherapy, but despite all efforts, the patient evolved to death. Treatment refractoriness and leukemia transformation suggest that t(11;16)(q23;q24) with KMT2A-r was associated with poor prognosis. This study reinforces the importance of characterizing new chromosomal alterations and their impact on prognosis in MDS.
Microsurgical anatomy of medial temporal lobe in North-West Indian population: Cadaveric brain dissection
Authors: Patra Devi , Tewari Manoj , Sahni Daisy , Mathuriya Suresh
Published: January 2022

Aim: The medial temporal lobe (MTL) is a highly complex neuroanatomical structure of tremendous neurosurgical importance. It is a common site for epilepsy, vascular lesions, and tumors. Owing to the critical location behind the sphenoid wing, it is more prone for traumatic contusion often with surgical implications. Hence, its microneurosurgical anatomy needs to be evaluated in detail. Materials and Methods: Twelve formalin-fixed human cadaveric brains from North-west Indian population were dissected under neurosurgical microscope and various dimensions of the MTL and their distance from important neurovascular structures were measured. Results: The MTL consists of important neural structures such as parahippocampal gyrus, uncus, hippocampus, temporal horn, and choroidal fissure. The average distance of tentorium from the uncus was 1.96 mm. The temporal horn and the inferior choroidal point were located from the anterior temporal pole at 22.9 mm and 30.9 mm, respectively. Important vessels that are intimately related to the MTL were anterior choroidal artery (AchA), posterior communicating artery, the P1 segment of posterior cerebral artery, and the M1 segment of middle cerebral artery. Conclusion: Complex anatomic and cytostructural organization makes the MTL unique. In this study, along with the descriptive anatomy, morphometric measurements of various structures were performed. The uncus and its relation to other neurovascular structures is well described in literature, but its exact distance from them as determined in this study is particularly helpful in guiding the surgeons while approaching in this area. Knowledge of the distance of the temporal horn from various surfaces is important while opening the temporal horn to avoid unnecessary damage to nearby structures.

Authors: Mak Siu , Qiu Liming , Ng Yew
Published: January 2022

Introduction: Surgical oculomotor nerve palsy(ONP), defined by ptosis, ophthalmoplegia, diplopia and pupillary dilatation, is associated with intracranial aneurysms, especially posterior communicating artery (PcomA) aneurysms. Treatment of PcomA aneurysms include endovascular coiling and surgical clipping. This study retrospectively compared the recovery of ONP in patients who underwent endovascular coiling or surgical clipping. Methods: A retrospective review of patients with PcomA aneurysms who presented with ONP between 1998 and 2012 in the National Neuroscience Institute, Singapore, was performed. Inclusion criteria included adult patients of age above 21 who have radiologically confirmed PcomA aneurysms with presentation of ipsilateral ONP. The aneurysms may be unruptured or ruptured with WFNS grade 2 subarachnoid hemorrhage (SAH) or better. Only patients with completely surgically or endovascularly obliterated PcomA aneurysms with regular follow-up are included. Results: A total of 22 patients were recruited. They were treated by either endovascular coiling or surgical clipping. The two groups of patients were demographically comparable, with 11 patients in each arm. 13 (59%) patients had unruptured aneurysms and 9 (41%) had WFNS grade 2 or better SAH. 13 (59%) patients presented with complete ONP and 9 (41%) had partial ONP. 64% of patients who underwent surgical clipping had resolution of ONP completely, compared to 18% of endovascularly coiling (P = 0.03) at 1-month follow-up. Conclusion: Compared to endovascular coiling, surgically clipped PcomA aneurysms are associated with a faster rate of full recovery of ONP.

Background: Postoperative pain and cerebrospinal fluid (CSF) leak are common known complications of spinal surgery, both having a synergistic effect on each other. Thus, both need to be dealt simultaneously. Double drug impregnated autologous coagulum patch (DDIAC) is a novel method which reduced both incidences of postoperative CSF leaks as well as pain. Methodology: Twenty-seven patients undergoing lumbar disc surgery without instrumentation were included and randomized into DDIAC and single drug impregnated autologous coagulum patch (SDIAC) group. The patients were assessed postoperatively with visual analog scale (VAS). Results: There were 21 males and 6 females in the study. Seventeen (63%) patients got randomized for DDIAC patch application and other 10 (37%) patients entered the control arm group (SDIAC) patch use. Preoperative VAS was 5 in both the groups. The average postoperative VAS was 3.01 in DDIAC arm and 4.29 in control arm. The average analgesic shot required in the DDIAC group was 0.41 in 24 h and SDIAC group was 4.1 in 24 h. In DDIAC group, none of these patients had CSF leak from the surgical wound till discharge from the hospital. In the SDIAC group, one (10%, n = 10) patient had CSF leak. Conclusions: DDIAC patch was effective in controlling pain in the postoperative period; however, few patients may require analgesic shots for pain management. SDIAC patch may control some pain in the immediate postoperative period; however, this was not sufficient for a longer postoperative period.

Objective: To evaluate the effectiveness of dural venous sinus sacrifice as a treatment of aggressive type cranial dural arteriovenous fistulas (dAVFs) in terms of both clinical outcome and angiographic outcome. Materials and Methods: One hundred and twenty-eight patients with 163 aggressive type cranial dAVFs who were treated with dural sinus sacrifice were retrospectively reviewed. Clinical and angiographic outcomes were analyzed. Procedural complications were also recorded. Only 103 patients (80.5%) who had been following up for at least 90 days were analyzed for clinical outcome. Results: There were 53 males and 75 females with age ranging from 20 years to 93 years (mean age 55.44 years). The overall angiographic cure rate of dural venous sinus sacrifice as a part of the treatment of aggressive dAVFs was 81.6%. Considering clinical outcome (average duration of follow-up was 2 years and 6 months), 75 patients (72.8%) had clinical improvement and 21 (20.4%) were clinically stable. Worsening of the presenting symptoms was observed in 7 patients (6.8%). Procedural complications were found in 5 patients (3.9%). Conclusion: Dural venous sinus sacrifice is a safe and effective treatment strategy with high angiographic cure rate, good clinical outcome, and low incidence of procedural-related complication.

Authors: Houssem Abid , Helene Cebula , Francois Proust , Salvatore Chibbaro
Published: January 2022

Prostate carcinoma rarely develops intracranial metastasis. In case it does, the dura is the most affacted area. In general, brain computed tomography (CT) findings mimic subdural hematoma making surgery challenge. We report the case of a 52-year-old male, presented as an emergency with a month history of headache, progressive temporospatial disorientation, mental confusion, and abrupt consciousness deterioration up to coma occurring few hours prior admission. An urgent brain CT scan showed a subdural collection in favor of a chronic subdural hematoma. The patient underwent surgery by standard burr hole, and surprisingly, peroperatively, there was a very bloody diffuse thickening of the dura without a real hematoma obliging to switch to a large fronto-temporoparietal craniotomy revealing a subdural mass that was completely removed. Histopathology disclosed a metastatic prostatic carcinoma confirming that such a subdural collection could behave as a great simulator. A contrast brain CT scan, is advisable, even in emergency, in selected case, with atypical images finding, especially if, a malignant disease is already known; the former could be of great help in the differential diagnosis and the best prompt management.
Intracranial hypertension secondary to cervical dural arteriovenous fistula
Authors: Pulhorn Heinke , Chandran Arun , Nahser Hans , Wilby Martin , McMahon Catherine
Published: January 2022

Idiopathic intracranial hypertension (IIH) is a disease of mainly unknown etiology. Latest theories as to the pathogenesis have postulated a final common pathway of cerebral venous hypertension secondary to venous outflow impairment leading to decreased cerebrospinal fluid absorption. We present the case of a 42-year-old female who was treated for several years for headache and for approximately 12 months for IIH until appropriate imaging showed a right-sided cervical dural arteriovenous fistula (AVF) at the level of C4. The patient's IIH symptoms resolved following surgical excision of the fistula. We suggest that the cranial venous outflow impairment secondary to the cervical AVF was responsible for intracranial hypertension and that complete investigation of IIH patients should include imaging of the neck vasculature.

Authors: Kim Ji Seul , Kim Jun Ho , Lee Eun Young
Published: January 2022

Objectives : This study was conducted to investigate the applicability of plant growth promoting microorganisms during restoration through re-vegetation of damaged topsoil.Methods : As the vegetation to be applied to the restoration site, Weigela subsessilis, Spiraea prunifolia, Pine densiflora, Pennisetum alopecuroides were selected. An attempt was made to isolate plant growth promoting microorganisms from the root zone of plants of the same species inhabiting domestic park sites and hiking trails. Plant growth promoting activities such as phosphate solubilization ability, siderophore production ability, IAA production ability, and ACC deaminase production ability were examined, and the species to be finally applied was selected and then identified. Among the strains whose plant growth promoting activity was confirmed, Arthrobacter sp. 1B2 and Paraburkholderia terrae 1P2 were applied to the genitalia and pine, respectively, and a pot experiment was conducted to confirm the activity.Results and Discussion : Forty-five strains were isolated from Weigela subsessilis, Spiraea prunifolia, Pine densiflora, Pennisetum alopecuroides and the IAA-producing ability and ACC deaminase-producing ability were confirmed for 16 strains whose phosphate solubilizing ability and siderophore-producing ability were confirmed. After selecting and identifying strains with excellent plant growth promoting ability, strains such as Cupriavidus sp, Arthrobacter sp., Pseudomonas fluorescens, Pseudomonas sp., Paraburkholderia terrae were obtained. Among them, Arthrobacter sp. 1B2 and Paraburkholderia terrae 1P2 strains were applied to genitalia and pine, respectively, and it was confirmed that plant growth was promoted.Conclusions : Bioassay experiments and field applications using plant growth promoting microorganisms have been mainly studied for herbaceous species (Grandaceae, corn, oats, etc.). However, in this study, the applied plants are shrubs class, which do not significantly grow in length, targeting damaged areas with high subsoil content, which are poor in environment and insufficient in organic and inorganic matter. Therefore, it is meaningful in that the activity of plant growth promoting microorganisms focused on absorption of inorganic substances, such as phosphate solubilization activity and siderophore ability, was investigated and the activity was confirmed by performing a bioassay.

Abstract

This study aims to determine the effect of the microbiological quality of broiler chicken meat that is marinated using pineapple extracts with different storage times at refrigerator temperature (180C). The stages of this research consisted of 2 stages, namely the first stage of making pineapple extract from fresh pineapples and the second stage was the marination process in which the broiler chicken meat samples were marinated using pineapple extract with a concentration of 30%. The experimental design used in this study was a completely randomized design (CRD) with one treatment factor (0 days, 3 days, 6 days, 9 days and 12 days) with each treatment repeated 4 times, in order to obtain 5 x experimental units. 4 = 20 experimental units. The microbiological analysis observed was the inhibition zone analysis and Total Plate Count (TPC). Giving marination with pineapple extract to the storage time of chicken meat has a significant effect on the inhibition zone. The highest zone of inhibition was 3.23 mm (for 6 days) while the lowest zone of inhibition was 2.21 mm (for 0 days). Provision of pineapple extract marination on the storage time of broiler chicken has a significant effect on the TPC. The highest TPC was 2.29 (for 12 days) while the lowest TPC was 0.30 (for 0 days).

Since the Prime Minister signed the decision approving the project 32/2010 on March, 25, 2010 “Development of Social Work Profession in Vietnam in the period of 2010 – 2020”, social work has strongly developed in many different areas including the medical field. Specifically, the Ministry of Health approved the project “Development of the Social Work profession in the health sector from 2011 through 2020” and the Circular 43/2015 on “The social work activities in the hospitals and the organizational form to perform the social work activities in hospitals”. These documents are fundamental to carry out social work activities in hospitals. However, this is a new field so the implementation of these activities is still difficult and lacks detailed supporting guidelines. This study was conducted to assess the status of the five main activities of social workers in hospitals regulated under Circular 43/2015, thereby providing solutions to improve the effectiveness of social work activities.

Published: January 2022

Evidence-based cessation assistance increases cessation rates. Activating preferences during decision making could improve effectiveness further. Decision aids (DAs) facilitate deciding by taking preferences into account. To develop effective DAs, potential end users' (i.e., individuals motivated to quit) needs and experts' viewpoints should be considered. Therefore, the aim of this needs assessment was: (1) To explore end users' needs and (2) to obtain consensus among smoking cessation counsellors and scientific experts to develop a self-administered DA to support end users in choosing cessation assistance. Data was gathered via two approaches: (1) twenty semi-structured interviews with potential end users and (2) two three-round Delphi studies with 61 counsellors and 44 scientific experts. Interview data and the first Delphi rounds were analysed qualitatively, the other Delphi rounds were analysed quantitatively. Potential end users acquired information in different ways, e.g., via own experiences. Important characteristics to decide between tools varied, however effectiveness and costs were commonly reported. Experts reached consensus on 38 and 40 statements, e.g., tools should be appropriate for users' addiction level. Although some trends emerged, due to the variation among stakeholders, a 'one size fits all'-approach is undesirable. This heterogeneity should be considered, e.g., by enabling users to customise the DA.

تهدف المجتمعات خصوصا المتقدمة منها من تنظيم قوانين رعاية الحدث أو الطفل هو ضمان تحقيق أكبر قدرٍ من هذه الرعاية، ولا يمكن أن يتم تحقيق هذه الرعاية والاهتمام بالحدث أو الطفل دون ضمانات وضوابط وخطط مستقبلية ودراسات عملية تبين مكامن الخلل في الأداء والسلبيات، وتشخيص الايجابيات لغرض تبنيها وتنميتها والتي ترافق عملية الرعاية وتتزامن مع عمر الحدث أو اللاحقة بعد جنوحه، في سبيل إعادته وتأهيله ضمن المجتمع، مع تطبيق المبادئ العامة لحقوق الإنسان والمواثيق والاتفاقيات التي تحكم قضايا الطفل والأحداث، وتأتي خصوصية هذا الموضوع من كون أنَّ العناية ببرامج الوقاية والرعاية الاجتماعية الخاصة بالأحداث تساهم في التقليل من احتمالات الانحراف والإجرام، والنص على مسؤولية الأولياء في حال إهمالهم لواجباتهم تجاه الحدث إهمالا يؤدي به إلى الانحراف والتشرد أو الجنوح، وكذلك إفراد تدابير وقائية خاصة من شأنها العمل على تأهيلهم بصورة تضمن اندماجهم من جديد بين أوساط المجتمع، ولا تأتي هذه النتيجة إلا بموجب النص على نظام قانوني يتمثل في ضرورة إلزام المجتمع في المساهمة في إصلاح الحدث من خلال تضامن اجتماعي بين كل أفراد المجتمع لغرض الأخذ بيد الحدث نحو السلوك الصحيح، والعمل على معالجة ما أفسده الجنوح من سلوكيات الحدث، فالتضامن الاجتماعي بالرغم من كونه مصطلحاً يحمل بين طياته مختلف الرؤى باختلاف السياسة الجنائية الوقائية المتبعة في دولة معينة عن دولة أخرى، إلا أنه أضحى اليوم من المبادئ المتفق على ضرورة تفعيلها والعمل على إيجادها في نطاق القوانين الخاصة برعاية الأحداث.
