According to the three-layer airport runway, based on spherical cavity-expansion theory and considering interface effect of concrete-macadam-soil by analyzing kinetic energy projectile penetrating layered target of concrete-macadam-soil, penetration models of concrete cratering, concrete pore-forming, macadam pore-forming and soil pore-forming are established. In addition, numerical solution of control equations is carried out by using Runge-Kutta method. And the Time-history curve of residual velocity is obtained. The theoretical analysis shows that because of the interface effect, the penetration resistance of projectile suffered on concrete layer and macadam layer when moving , is related not only to penetration velocity, mass, projectile shape and medium character, but also to penetration depth, which is the biggest difference compared with penetrating into single layer. Finally, by means of finite element simulation, the process of oblique penetrating into multilayered medium of airport runway is simulated by three dimensional numerical analysis. Thus, the influence of the penetration velocity and the boundary of the runway on the penetration process were studied. The results show that the presence of the multi-layer media interface of the runway accelerates the attitude of the projectile body; the smaller the penetration rate is, the more obvious the phenomenon is. At the same time, the overload response of projectile body is changed. The research results have laid a foundation for the further research on the technology of the composite medium penetration into the airport runway. They also have reference value for the research on the failure of civil engineering materials under the action of dynamic loads.

In this investigation, exact displacement functions were used to analyze thick anisotropic rectangular plates of two boundary conditions; simply supported on all edges (SSSS) and clamped on all edges (CCCC). Third order shear deformation model was employed in the formulation of the total potential energy functional for thick anisotropic rectangular plate. This total potential energy functional was reduced to the governing equation and compatibility equations for thick anisotropic plate. The governing equation and compatibility equations were solved to obtain the general displacement functions. By satisfying the boundary conditions for SSSS and CCCC plates their distinct displacement functions were obtained. These displacement functions were used to obtain the stiffness coefficients (k-values) for the plates. Minimizing the total potential energy functional with respect to the coefficients of the displacement functions gives the formulas for calculating the values of the coefficients. At this point, the displacements and stresses of the plates were calculated at various angles fiber orientations (0^0, 〖15〗^0, 〖30〗^0, 〖45〗^0, 〖60〗^0, 〖75〗^0 and 〖90〗^0) and various span-to-thickness ratios, α (5, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100). The results obtained were close to the results of other scholars.
Sphingomonas are ubiquitous bacteria, widely distributed in the nature, soil and water including the water sources in the hospital environment, contains at least more than 30 species, which of only paucimobilis is an occasional pathogen.1 It is one of the non-fermenting Gram-negative bacilli that is emerging as an opportunistic pathogen [7]. S.paucimobilis is considered to be the organism of low virulence likely owing to absence of endotoxin and typical polysaccharide and thus responsible for less mortality and morbidity but sometimes can lead to septic shock. To support this, retrospective study conducted at our hospital on total 1580 inpatient (IP) blood samples for culture yielding positivity of 0.44% for the growth of S.paucimobilis, did favour the survival of the all the patients. All the blood isolates produced distinct white or off-white coloured colonies on blood and chocolate agar hence referred as “Bleached Sphingomonas paucimobilis.”

Neurodegenerative diseases (NDD) are a major global public health concern and a leading cause of disability-adjusted life-years, moreover, therapeutic options are limited. Brain targeting has always been challenging due to the presence of various physiological barriers, of which one of the most robust barriers is Blood Brain Barrier (BBB). The BBB consists of endothelial cells which are the tight layers surrounded by astrocyte foot processes, and these anatomic features together constitute a significant barrier that hampers the delivery of drugs to the central nervous system (CNS). In the past few decades, the nose-to-brain targeted delivery has received a great deal of attention because of factors like the rapid onset of action, increased bioavailability, manageable surface area and avoids the first-pass metabolism, thus considering it as a non-invasive, convenient and reliable approach that may overcome the challenges associated with nose-to-brain targeted delivery. However, this strategy still possesses significant limitations, which led to the development of nanotechnological approaches like solid lipid nanoparticles, polymeric nanoparticles, nanoemulsions, liposomes and polymeric micelles, thus circumventing these barriers. The present review article highlights a complete understanding of every aspect related to nose-to-brain delivery: mechanism involved in the transport of drugs from nose-to-brain via BBB by complex pathways, strategies to overcome the barrier-BBB, recent examples, and applications of nose-to-brain targeted delivery using nanotechnologies for brain gliomas and other neurological disorders.

This work concentrated on the analysis of thick anisotropic rectangular plate through exact approach using third order shear deformation theory. Refined plate theory assumptions were relied upon to formulate the total potential energy functional. Displacement field, kinematic relations, constitutive relations and stress displacement relations were also obtained from the assumptions. Kinematic relations and Stress-displacement relations were substituted into the universal strain energy equation to formulate the strain energy equation. Total potential energy functional for the analysis of thick anisotropic rectangular plate was obtained by adding the external work and strain energy equation together. The total potential energy functional was differentiated with respect to the out plane deflection (w), shear deformation rotation in x direction (_x) and shear deformation rotation in y direction (_y). This yielded the governing equation and two compatibility equations of thick anisotropic rectangular plate. Third order polynomial shear deformation function which was derived by Ibearugbulem et al. was relied upon to obtain the displacement functions. From these displacement functions, the unique displacement functions for the SSSS plate boundary condition were determined. Also the stiffness coefficients were calculated for the SSSS plate boundary condition. The formulas for calculating the coefficients of the displacements were combined with elastic equations to determine the novel formulas which were used in calculating for displacements (u, v and w) and stresses (σ_RR,σ_QQ,τ_RQ,τ_RS and τ_QS) at various angle fiber orientation (0^0, 〖15〗^0, 〖30〗^0, 〖45〗^0, 〖60〗^0, 〖75〗^0 and 〖90〗^0) and various span to thickness ratio, α (5, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100). These formula were used to analyze typical anisotropic rectangular thick plates. The results obtained were shown on Tables 1, 2, 3, 4 and 5. These numerical results obtained showed some level of agreement with previous works by other scholars. Hence the developed method is recommended for analyzing thick rectangular anisotropic plates.

The problem of juvenile dealing with the law is one of the problems surfaced in the effort to protect and to fulfill juvenile's rights in Indonesia. Currently, the problem is handled with Law No. 11 of 2012 concerning the Juvenile Criminal Justice System (SPPA) which regulates the judicial process for juvenile in conflict with the law, including juvenile in conflict with the law, especially regarding their assistance in the court. The existing problems show that the SPPA Law does not reflect the value of justice on the legitimacy of legal acts of juvenile in conflict with the law. This study uses a socio-legal research approach with data sources, namely primary data obtained in the field and relevant literature as a secondary data. The data analysis used was a descriptive-analytical method. The results the author's research shows that the protection of the legitimacy of juvenile's legal acts in conflict with the law in the juvenile criminal justice system in Indonesia has not shown the value of justice optimally because not all juvenile who undergo a judicial process in child criminal cases receive assistance from their parents or biological parents them, it is not uncommon for many parents to feel embarrassed to accompany the criminal justice process for their juvenile. From this, efforts are needed to reconstruct the legality of legal acts of juvenile, namely reconstructing and adding new constructs of Article 1 point 18 with new constructions and adding one new construction as point 18a.

The problem discussed in this study involves is that there is yet to be a law protection for Multiple or Separate-Editor in case if company is declared bankrupt and is unable to pay its debts as a whole that could reflect Justice Value. The method of research used in this research is juridical-empirical where the research type is qualitative research with a sociological juridical approach (Socio-Legal Approach). The results of this study indicate that the position of the separate-creditors in the company bankruptcy currently has a priority in obtaining repayment of their accounts. Manpower legal protection in the event of a debtor who has been declared bankrupt before and after the Constitutional Court decision No. 67 / PUU-XI / 2013 are as follows: prior to the Constitutional Court decision it was assumed that labor wages remained under separate-creditors, taxes, auction fees, and curator fees and were deemed not to contradict Article 28D paragraph (1) and paragraph (2) of the Indonesian Constitution Law Year 1945. After the Constitutional Court decision, the position of workers' wages according to the Bankruptcy Law and the Civil Code takes precedence. The reconstruction of the position of the separate-creditor as offered by the author is by reconstructing the decision of the Constitutional Court No. 67 / PUU-XI / 2013 to better reflect the value of justice.

The implementation of the termination of investigations by the Indonesia's Commission of the Eradication of Corruption (KPK) in Indonesia has not been able to provide justice due to the unclear regulatory factors in Law Number 19 of 2019 concerning the Amendment of the KPK Law. Based on this, the problem raised by the writer in this study is what are the obstacles that arise in in the process of investigation by the KPK in realizing the principles of fast, cheap, and simple Investigation and how to reconstruct the termination of an investigation by the KPK from the perspective of Law Number 19 of 2019. The research method used in this research is normative juridical using secondary legal materials and a qualitative analysis. The results showed that in its development, the investigation policy for suspects who died had changed since the second amendment to Law no. 30 of 2002. Several considerations behind the change in the policy of stopping KPK investigations are to provide protection for the rights of suspects. To deal with this, a reconstruction of the policy to stop investigations in the criminal justice system for corruption cases under the authority of the Corruption Eradication Commission requires reconstruction in Article 40 paragraph (1) of Law no. 30 of 2002, by adding to the provision that the KPK can stop investigating and prosecuting corruption cases where the investigation and prosecution are not completed within a maximum period of 2 (two) years or if there is not enough evidence, not a criminal act and for the sake of the law.

Background: Pre-eclampsia affects up to 10% pregnancies worldwide and is one of the foremost causes of poor maternal and foetal outcome. The situation in India is even grave with high rate of maternal mortality due to pre-eclampsia. Though multiple risk factors are associated with pre-eclampsia, it is known that first pregnancy itself is a significant pre-eclamptic risk factor. Therefore, in this study we intent to gauge the effects of low dose Acetyl salicylic acid (Aspirin) among pregnant women in prevention of pre-eclampsia. Materials and Methods: This randomized controlled study was conducted in Department of Obstetrics and Gynaecology of Mamata Medical College and General Hospital. Total 100 patients were enrolled in this study. Pregnant women with and without any other pre-eclamptic risk factor consulting before the 16th week of amenorrhea were selected in the study. One group i.e. Treatment group (n=50) was given 75mg/day aspirin orally after breakfast to one week before estimated date of delivery while the other group received no aspirin. Both groups were followed for regular antenatal check-up. Results: The treatment group who received acetyl salicylic acid (aspirin), the age ranged from 20-35 years with a mean age of 24.81±3.12 years. Maximum number of cases belonged wot age group of 26-30 years. The treatment group who received acetyl salicylic acid (aspirin), the age ranged from 20-35 years with a mean age of 25.21±4.29 years. Moreover, we found pre-eclampsia in aspirin group was of lesser severity as compared to those in control group. Further, proportion wise the risk of pregnancy induced hypertension and eclampsia were also reduced with aspirin, however, these were not found statistically significant. Conclusion: Our study highlights the beneficial effect of low-dose acetyl salicylic acid in decreasing hypertension and proteinuria. This study also confirms the efficacy of acetyl salicylic acid in decreasing caesarean section, maternal mortality and morbidity.

Antioxidant activities of some species of Mangnifera indica seed kernel (sucking mango, bush mango and opiororo mango) extracts were studied. The antioxidants capacities of the mango seed extracts were compared to some known synthetic antioxidant. Results obtained showed that the three different species of Mangnifera indica seed kernel which have 30.24+0.030%, 21.11+0.010% and 15.14+0.020% for sucking, bush and opiororo mangoes respectively had a lower scavenging capacity compared to the synthetic positive control standard (vitamin C) which recorded 32.57+0.001% in DPPH radical scavenging assay. Mangnifera indica specie B (bush mango) had the highest scavenging capacity (66.76+0.014%) compared to the synthetic positive control BHT (64.40+0.020%) in the reducing power determination assay. Mangnifera indica specie B (bush mango) and specie C (opiororo mango) had higher scavenging capacities of 14.64+0.031% and 14.29+0.019% for hydrogen peroxide scavenging capacity compared to synthetic sodium pyruvate which has 13.01+0.009%. Proximate composition of three varieties of mango seeds was also determined. The percentage moisture, ash crude fat, crude fibre, protein and carbohydrate contents was determined using A.O.A.C. method. Opiororo mango and Sucking mango had similar values for moisture content (8.00%) while Bush mango had comparable value of 8.05%. The ash content ranged between 0.40 - 1.80% and Bush mango had the highest value of 1.80±0.03%. The fat content was observed to be between 14.29±0.05% and 27.14±0.01% with sucking mango having the highest fat content (27.14±0.01%). Bush mango and Opiororo mango had similar values for crude fibre (49.50%) while sucking mango had comparable value of 49.00±0.03%. The crude protein ranged between 9.26 - 14.27%. This study suggests that the seeds may be nutritionally potent with appreciable high levels of nutrients and energy which can be incorporated into feed/food.

The habitual carriage of heavy school backpacks by scholars has been associated with a clumsy forward leaning compensatory posture that has become a concern to both parents and medical practitioners. This report documents the change in sagittal plane posture by quantifying the variation in craniovertebral (CVA) and standing pelvic angles (SPA), as well as vertex and acrominale heights during the loaded (carrying of the school backpack) versus the unloaded (not carrying the school backpack) phases. The school backpack weighed 6.8kg (20.0% of the scholar’s body mass). The scholar carried the straps of the backpack on both shoulders respectively. There was a significant difference in vertex and acrominale heights during loaded versus unloaded phases (p=0.02). A positive association was found between the anterior pelvic tilt and diminished vertex height (r=0.99) indicating that heavy backpack carriage diminishes the child’s vertex height by anteriorly rotating the pelvis. Furthermore, there was a positive association with the change in CVA and SPA (r=0.89) suggesting that carrying heavy backpacks produces a complimentary diminished CVA with an increased SPA in order to accommodate the increased load on the vertebral column.

Mercury (Hg) is a natural chemical element found in the Earth's crust in three forms, namely elemental, inorganic and organic. Mercury is formed naturally through anthropogenic activities, volcanoes or seepage of groundwater through mercury deposits. Mercury exposure cause harm to pregnant women and the fetus. Some mercury compounds bioaccumulate and cross the placenta to the fetus. They also pollute colostrum and breast milk, causing severe health problems for newborns such as, disabled and a tendency to hyperactivity or autism. High fish consumption increase mercury levels in pregnant women. Fish intake during pregnancy is associated with mercury levels in hair in pregnant women, mainly the frequency of fish intake, types of fish and the amount of fish consumed. This study aims to determine the relationship between fish consumption and mercury levels in the hair of pregnant women. Hair samples were taken from 53 pregnant women in Bulukumba district using purposive sampling technique. Hair analysis used Atomic Absorption Spectrophotometer (AAS) AMA 254 with a wavelength of 253.7 µm. This research is analytic observational with a cross-sectional study design. The results showed that were 73.6% of mercury levels in the hair of pregnant women were abnormal, then 64.2% of pregnant women who consumed fish> 3 times / week and 35.8% of fish consumption < 3 times / week It is concluded that there was a significant relationship between fish consumption and mercury levels in the hair of pregnant women, but it was not significant for total fish consumption. The community is advised to use mercury friendly materials and tools and to the government to intensify education to vulnerable communities about the dangers of mercury in pregnant women.
