Design Development and Fabrication of Soil Drilling Machine for Plants – Review
Authors: Ikhar Dr. S. R.
Published: March 2024

Abstract: Today’s era is marching towards the rapid growth of all sectors including the plantation of trees to a large extent and the agricultural sector. Conventionally digging deep holes or larger diameter holes requires more work. So to reduce these losses we are planning to design a soil drilling machine for the plantation. A soil drilling machine is used to reduce the man's work and time for digging holes. These holes can be used for fixing engines and different plantations such as rubber plants, coconut, sugar cane, etc. The Project aims to Design Development and Fabrication of Soil Drilling Machine for plants which would be modified to overcome all the shortcomings of the existing Digging Machine. The project will be useful in providing a solution for a lowcost and comparatively safe auger that can be completely used by one person. This project will be provided with a safe and costefficient alternative to use for plantation or other purposes. This project will help understand the shortcomings of manual and power-operated Digging machines and provide possible solutions. Hence, this project will reduce the chances of auger-related injuries and also increase the stability and usability of the same. This project will help people to use Soil Drilling Machines comfortably and work will be done smoothly and efficiently. Our project aims to reduce the cost of the machine and make it portable for easy carrying. So due to these reasons, we are using a petrol engine instead of a diesel engine and we attach a steel frame to it to make it portable. This project involves the design and fabrication of a soil drilling machine. The design of the soil drilling machine is done by SOLIDWORKS and the fabrication is completed employing various fabrication techniques

Published: March 2024

Abstract: However being rare in women, breast cancer can have a substantial morbidity and fatality rate. The goal of the current review is to ascertain whether breast cancer treatment and evaluation methods used on female patients are suitable for this type of cancer. In comparison to male breast cancer, female breast cancer differs biologically in that it is more common in some regions of Africa, has a higher frequency of oestrogen receptor positive, and has more aggressive clinical behavior. It reacts to chemotherapy and hormonal therapy, yet it is unknown what the best treatment plans are for female patients. Breast cancer in women is still a rare condition. The majority of what we currently know about its biology, natural history, and methods of therapy has been derived from research on its female counterpart.

jako forma praktyki pomocowej rozwija się intensywnie. Świetlice socjoterapeutyczne są miejscem specjalnie dedykowanym do prowadzenia zajęć socjoterapeutycznych dla dzieci i młodzieży. Celem prowadzonych analiz jest więc skonfrontowanie definicji socjoterapii z tym jakie informacje na temat tej formy terapii może uzyskać osoba chcąca skorzystać z pomocy w świetlicy socjoterapeutycznej ze stron internetowych, profili w serwisach społecznościowych oraz rozmów telefonicznych z pracownikami/pracowniczkami. Metodą zbierania danych w tym projekcie jest analiza danych zastanych (desk research) uzupełniona o informacje z wypowiedzi osób pracujących w badanych placówkach, natomiast metodą analizy danych jest analiza szablonowa (template analysis). Analizy dotyczyły 40 świetlic socjoterapeutycznych w Gdańsku, Katowicach i Poznaniu. Informacje o tym jak placówki komunikują o swojej pracy pokrywają się w dużej części z tym, jak definiowana jest socjoterapia w literaturze przedmiotu. Uzyskane dane wskazują jednak, że socjoterapia rozumiana jako forma pracy z małą grupą oparta na procesie grupowym, nie jest jedyną r formą pomocy ealizowaną w świetlicach (i być może nie najważniejszą) oraz, że pogłębiona praca terapeutyczna nie we wszystkich placówkach może być realizowana ze względu na sposób organizacji pracy.

Authors: Salsabila Ajeng Zulfa , Yuliani Anik , Amelia Risma
Published: March 2024

This study was intended to analyze the impact of distance learning on students' ability to solve math problems. Using the literature search method, this research was carried out by analyzing a range of types of information in qualitative and quantitative data from various texts based on previous studies. The literature exploration system uses a variety of references similar to books, exploration journals, and distance literacy operation modules that analyze studentsâ€™ mathematical problem-solving skills. The results of this study validate that distance learning can affect studentsâ€™ mathematical problem-solving skills when teachers use innovative methods and interactive learning media. In fact, students can develop their mathematical problem-solving skills through meaningful learning. This means that students can build their own knowledge with learning that requires independent study on the part of students so that they can construct conceptual discoveries from the material being taught. Students' mathematical problem-solving skills can also be affected by the active role played by students in distance learning. For this purpose, it is necessary for educational institutions to apply appropriate methods of learning and media that allow students to have an active role in the educational process. In addition, educational institutions must strive to provide effective and efficient communication, mentoring, and support services to students and parents.

Authors: Gunawan Muhamad , Yuspriati Devi Nurul
Published: March 2024

This study aims to find out how well vocational students solve mathematical problems based on the composition function material. Mathematical problem solving ability is an ability that must be mastered by students because this ability is the core of mathematics. The location of this research is at SMK TI Garuda Nusantara and the main object of research is class XI students totaling 32 people in one class. The author used a descriptive qualitative approach. Several test questions were used as data collection methods. of 32 students in one class. It can be said that only 9 people were able to complete the test questions and get a good rating on each indicator. The results show that the problem solving ability of students in class XI of SMK TI Garuda Nusantara is classified as sufficient or moderate. This is very clear from the fact that only 28% of students who achieved perfect scores in the good category. 56% were rated medium, and 16% were rated low. The acquisition of the highest indicator value is in problem solving ability, while the lowest indicator is in the indicator of understanding the problem, this is due to the lack of understanding of basic mathematical concepts in students. In order for students' problem-solving skills to improve, researchers suggest that further research should use learning models or media that can help students understand mathematical concepts.
Association between Timing of Albuterol and Care Escalation to the intensive care unit Among Pediatric Patients admitted with Status Asthmaticus
Authors: Ahmed Zoha S. , Morrison John , Fierstein Jamie L. , CPH Alexandra Miller MPH , Jabre Nicholas
Published: March 2024

Children admitted to the ward for status asthmaticus may not receive the
first albuterol treatment on schedule. We sought to determine if a
difference in timing between scheduled and actual first dose of
albuterol is associated with care escalation to the pediatric intensive
care unit (PICU). We conducted a single-center case-control study of
children 2-18 years admitted from the emergency department (ED) to the
ward for status asthmaticus. Cases required transfer to the PICU within
24 hours of admission. Groups were compared using Fisher’s exact or
Mann-Whitney U tests. Firth multivariable logistic regression
estimated the association between dose timing and odds of transfer to
the PICU. Groups did not differ by demographics, comorbidities, or
asthma severity risk factors. The median (IQR) time difference between
scheduled and administered first dose of albuterol was 0 (-14 to 63)
minutes for cases and 16 (-6 to 42) minutes for controls ( p=.4).
Fifty percent of cases received delayed treatment compared to 63% of
controls ( p=.28). The adjusted analyses demonstrated that as the
time difference between scheduled and administered albuterol increased
by 1 minute, odds of care escalation to the PICU remained the same
(OR=1.0, 95% CI: 0.9 to 1.0; p=.2). Receiving first albuterol
treatment on the ward at a time different than scheduled was not
associated with increased odds of transfer to PICU. Delayed albuterol
administration did not vary with PICU transfer. Delays in treatment,
when taken in the context of evidence-based asthma pathways, did not
significantly impact hospital course or quality of care.

Background: Several major sensitization profiles have
been described in children with asthma, but it remains unclear how these
profiles relate to asthma phenotypes. The aim of this study was to
determine allergenic sensitization profiles in a megacity cohort (SAMP).
Methods: This was a cross-sectional analysis performed
from 2011 to 2015 including preschool and school-age children with
severe and moderate asthma from the SAMP cohort. We performed ALEX
multiplex array and carried out cluster analysis. Results: Data
from 367 children were analysed: 224 of preschool age and 143 of school
age, respectively 84 (38%) and 114 (80%) presented at least one
allergic sensitization. At preschool age, three clusters were
identified: Cluster 1, Few sensitizations to inhaled allergen molecular
families and non-type 2 (T2) inflammation (n=61); Cluster 2, Predominant
sensitization to HDM molecular families. (n=16); Cluster 3, Severe
asthma with multiple sensitizations to inhaled and food allergen
molecular families (n=7). At school age, five clusters were identified:
Cluster 1, Few sensitizations to inhaled allergen molecular families and
non-T2 inflammation (n=43); Cluster 2, Predominant sensitization to HDM
molecular families (n=31); Cluster 3, Predominant sensitization to PR-10
family (n=25); Cluster 4, Severe asthma with predominant sensitization
to tropomyosin family (n=11); Cluster 5, Severe asthma with multiple
sensitizations to inhaled and food allergen molecular families (n=4).
Conclusion: These results underline the heterogeneity of
sensitization profiles in severe allergic childhood asthma. The most
severe asthma phenotypes were associated with multiple sensitizations to
both inhaled and food allergen molecular families as expected, and to
the tropomyosin molecular family, a novel finding.

The design of a wide band reconfigurable dual bandpass filter
with a wide band stop range is presented using a parallel cascaded
microstrip topology. In doing so, two cascaded cross-coupled filters are
implemented without the need to use an isolator; one quasi low-pass
filter and one quasi high-pass filter. Simulated results are presented.
A comprehensive review and side channel attack analysis on radiation-tolerant SRAM cells for aerospace, terrestrial and nuclear applications

Published: March 2024

In memory, single event upset (SEU) and single event multiple node upset
(SEMNU) have become the principal problems during the past four decades.
Significant dependability issues arise from these upsets in a variety of
applications such as space, terrestrial, military, and healthcare
sector. The use of scaled on-chip memory devices to store private and
sensitive data has grown dramatically in the last several years across
all the sectors. Memory devices are seriously at risk from non-invasive
side-channel assaults (SCAs), which extract secret and sensitive
information as well as during SEU/SEMNU, which may flip stored secret
and sensitive information. This article presents the history behind the
emergence of radiation-hardened circuits and survey of several
techniques to mitigate the impact of radiation over the past few decades
along with SCA based on leakage power analysis. By educating the
researchers on two crucial on-chip memory issues—radiation effect
SEU/SEMNU and SCA—this work seeks to accelerate co-design efforts.
The Value Expectation Bias in Test Anxiety Individuals: Test Specificity or Threat Generality?
Authors: Ou Yuhong , Zhou Renlai
Published: March 2024

The value expectation (reward or punishment) of outcomes based on
experience and current information decides whether to do and how much
effort to put into executing the current task. Individuals with test
anxiety have difficulty inhibiting test-related and test-unrelated
threat stimuli. We suggested that the excessive negative value
expectation for threat stimuli played an important role. Thus, the
current study investigated the value expectation towards test-related
and test-unrelated threat stimuli in test anxiety individuals. The ERP
results showed that, in the high test anxiety (HTA) group, compared to
neutral stimuli, test-related and unrelated threat stimuli induced more
negative FRN amplitudes following negative feedback and more positive
FRN amplitudes following positive feedback. Moreover, the FRN amplitudes
induced by negative feedback following test-related and test-unrelated
threat stimuli were significantly more negative in the HTA group than in
the LTA group. In the FRN difference wave (d-FRN) results, test-related
and unrelated threat stimuli induced more negative d-FRN than neutral
stimuli. Additionally, the HTA group showed a more negative d-FRN than
the LTA group under the test-related threat condition. No differences
were found in the LTA group. In the ERD results of the beta band, the
ERD power induced by negative feedback following test-related threat
stimuli was significantly stronger than those following test-unrelated
threat stimuli in the HTA group. However, no significant differences
were found in the average P3 amplitude and ERS results in the theta
band. These findings suggested that individuals with HTA had a negative
value expectation for threat stimuli.

Driven by the goal to achieve sustainable mobility, mitigate climate
change, and reduce greenhouse gas emissions, electric vehicles (EVs)
represent a radical paradigm shift in the automotive industry.
Significant progress has been made in electric vehicle (EV) technology
in recent times, including enhancements in battery efficiency, range,
and charging infrastructure. As the main energy storage option for
electric vehicles, lithium-ion battery technology has advanced
significantly, increasing energy density and lowering costs. Wider
acceptance of EVs has also been encouraged by the development of
fast-charging stations and smart grid integration, which have greatly
solved issues with convenience and charging time. However, lithium-ion
cells used currently have a working temperature range of 15
C to 35 C. The temperature above
or below can affect the battery performance and range of the vehicle.
Thus, implementation of proper Battery Thermal Management System (BTMS)
is required to achieve effective cooling performance and maintain the
cells within operating range of temperatures. The current study focuses
on the use of fly ash nanoparticles dispersed in base fluid
water-ethylene glycol to be used as coolant in indirect liquid cooling
system. An ANSYS FLUENT model is developed for 14 LFP cylindrical cells
having 2S7P arrangement with serpentine cooling channel in between the
cells. The current study uses 5 % particle concentration fly ash
nanofluid as coolant to understand the rise in temperature at the outlet
for different flow velocities. The better cooling performance was
observed for fluid flow rate of 0.1 m/sec with an outlet temperature
rise of 311.976 K along with rise of 4 % in temperature compared to
inlet fluid flow temperature of 300 K. The percentage difference between
the rise in temperature of the outlet for the fluid at 0.1 m/sec and 3
m/sec is 3.07 % indicating effective cooling at lower fluid flow
velocities. Thus, by the use of Fly ash as nanofluid in battery cooling
application will certainly help to reduce the temperature of battery
pack and can provide to be a sustainable solution leading to lesser
degradation of environment.

The long transmission distance in wireless power transmission(WPT)
system will lead to a sharp decline in transmission efficiency, this
paper presents a novel ortho-octagonal double helix metamaterial that
can effectively enhance the transmission efficiency of WPT systems,
theoretically derived and experimentally verified the enhancement of
evanescent wave transmission by this metamaterial dielectric plate. A
WPT simulation system operating at 10.78 MHz is constructed by HFSS
software, and the effects of adding passive relay coils and different
shapes of metamaterials on the transmission efficiency are comparatively
investigated. Both simulation and experimental results show that the
transmission efficiency of the WPT system can be improved to different
degrees after inserting different shapes of metamaterials at the
transceiver end of the system. When the transceiver coil spacing of the
WPT system is greater than 22 cm, the effect of metamaterials on the
system transmission efficiency enhancement shows an increasing and then
decreasing trend as the distance increases. The positive octagonal
metamaterial improves 12% over the circular metamaterial in the
mid-range transmission distance due to its better magnetic coupling
effect. When the transceiver coil spacing is 22 cm, the open-circuit
voltage of the receiving coil after loading the metamaterial is
stabilized to be enhanced by nearly 5 times, and it has the best effect
at 30 cm, and the transmission efficiency is enhanced from 30% to 60%,
which verifies the effective enhancement of the metamaterial on the
transmission efficiency of the WPT system.

Published: March 2024

An extremely effective and straightforward multi-component reaction
strategy for the universally highly selective synthesis of 5-CF3
pyrimidine derivatives has been established. This method employs a
distinctive trifluoromethylation-cyclization strategy, introducing an
innovative reaction mechanism and avoiding the inherent selectivity
challenges in direct pyrimidine trifluoromethylation. The no-table
advantages of this work are the exceptional selectivity, extremely short
reaction time, and convenience of a one-pot synthetic procedure.
Cryptic genetic adaptation despite high gene flow in a range-expanding population

Published: March 2024

Signals of natural selection can be quickly eroded in high gene-flow
systems, severely challenging efforts to understand how and when genetic
adaptation occurs in the ocean. This long-standing, unresolved topic in
ecology has renewed importance because rapidly changing environmental
conditions are driving range expansions that, in many cases, necessitate
rapid evolutionary responses. To test for genetic adaptation in a
coastal marine species with high dispersal potential, we performed a
series of crosses on Kellet’s whelk (Kelletia kelletii) collected from
its historical and recently colonized range, and conducted RNA-Seq on
offspring that we reared in a common garden environment. We identified
2,770 differentially expressed genes between 54 samples with
historical-range and expanded-range ancestry. Using SNPs called directly
from the differentially expressed genes, we revealed parental population
structure that enabled us to assign “unknown” samples back to their
range of origin with unprecedented accuracy for a marine species (92.6
to 94.5%). The SNP with the highest predictive importance occurred on
triosephosphate isomerase (TPI), an essential enzyme for glycolysis and
glucogenesis, which also plays a role in cold stress response. TPI is
both highly upregulated and contains a non-synonymous mutation in the
expanded range, where ocean temperatures are colder than in the
historical range. Our findings pave the way for accurately identifying
patterns of dispersal, gene flow, and population connectivity in the
ocean by demonstrating that rapid genetic adaptation can occur even in
high gene flow species and that experimental transcriptomics can reveal
mechanisms for how marine organisms respond to changing environmental
conditions.

Introduction The aims of this study were to update our
experience with biodegradable polydioxanone (PDO) airway stents in
children focusing on effectiveness and safety, and to analyse the
factors involved in the different outcomes observed. Materials
and methods Retrospective study of patients managed with PDO stents
from 2012 to 2023. Variables collected: demographics, comorbidities,
indication , clinical baseline, stent size, location, complications,
clinical outcome, and time of follow-up. Statistical analyses were
performed in order to detect the eventual contribution of variables in
the different outcomes observed. Results 54 PDO stents were
placed in 26 patients (median age, 4 m). All showed severe symptoms of
central airway obstruction due to: tracheomalacia 9 patients,
bronchomalacia 5, tracheobronchomalacia 10, and tracheal stenosis 2.
Stent placement was uneventful in every case: 29 stents in the trachea
and 25 in main bronchi. 53,8% of patients needed successive stenting
and all exhibited comorbidities. Complete clinical resolution was
observed in 8 cases (30.7%), partial improvement in 13 (50%),
unchanged in 4 (15.3%), and worsen in one. Age had a significant
positive impact in outcome (6 months vs 3 m.; p=0.024). Additionally,
smaller stents were associated with a better outcome (20 vs 26 mm;
p=0.044). Granulation tissue was the most frequent complication
(34.6%). Five patients (19.2%) died due to severe comorbidities,
follow-up was complete in survivors (median, 58 m). Conclusions
PDO stents are safe and effective when dealing with severe
tracheobronchial obstruction. Stent-related granulation tissue continues
to be a relevant matter of concern. This issue together with increased
degradation times deserve further research.
