Proposal for an ideal method for attaching animal-borne data loggers to freshwater turtles
Authors: Ohtani Kentaro , Ushimaru Atushi , Iwata Takashi
Published: May 2023

Biologging involves the use of animal-borne data loggers to investigate
behavioral ecology and physiology, and is widely used in various
taxonomic groups, including freshwater turtles. Two methods of
attachment of the logger were used in previous studies on freshwater
turtles. Technological advances have led to a variety of devices and
experimental periods and their characteristics vary depending on each
species of turtle. Thus, the ideal attachment method for each species
and experimental purpose should be considered. This study proposes a new
method that utilizes quick-setting epoxy to bond the carapace to a
basement. We conducted field experiments on a wild Reeves’ pond turtle
and a wild red-eared slider. The new method was used for the pond turtle
and the traditional approach of drilling holes in the carapace for
attaching the logger with cable ties was used for the slider. The data
logger was deployed on the pond turtle for > 3 h and on the
slider for 26 days. Results revealed that the movement speed of the pond
turtle and the dynamic acceleration of the slider tended to be small in
the periods from sunset to sunrise. Although the duration of attachment
in the new method was short compared to previous studies, results show
that the method is useful for repeatedly attaching and removing the
device from turtles, as it is simple and noninvasive.

Published: May 2023

The aim of this research work is to analyse the biomolecules of pollen
present in seven different species of Solanum L. i.e., S. erianthum, S.
indicum, S. macranthum, S. melongena, S. sisymbriifolium, S. torvum and
S. xanthocarpum. The pollen grains were collected from plants growing in
Santiniketan, Sriniketan, Prantik and Bolpur of Birbhum district. The
flowering season, anthesis time, pollen morphology, pollen protein
profile were studied and total carbohydrates, proteins, lipids, amino
acids, DNA were estimated using standard methods. The flowering season
and anthesis time vary among the studied species. The size of pollen
grains varies between 17 x 16 µm to 68 x 72 µm. The total content of
carbohydrates, lipids and proteins were highest in S. xanthocarpum
whereas total free amino acid and DNA was highest in S. erianthum. The
S. macranthum reported lowest amount of total lipids, proteins and free
amino acids among all. The proline present in all species ranging
0.59-3.00 mg/g, an essential amino acid for pollen germination. The SDS-
PAGE of pollen protein revealed 44 major polypeptide bands of different
molecular weight ranging from 19 kDa to 135 kDa and variation in
polypeptide bands observed from 7 to 13. A dendrogram was drawn based on
morphology and biomolecules of pollen found that S. macranthum, showed
less similarity with other species and it placed alone in a separate
cluster.

NAD -dependent formate dehydrogenase from the
bacterium Staphylococcus aureus (SauFDH) plays an important role
in the vital activity of these bacteria. The gene encoding SauFDH was
successfully cloned and expressed in our laboratory. Since this enzyme
has the highest k value among the described
FDHs and also has a high temperature stability compared to other
proteins, it can be considered as a promising catalyst for regeneration
of NAD(P)H. The main disadvantage of this enzyme are high K
values. In this work, the principle of rational design
was used to reduce K . As a result, 9 catalytically
significant positions 119, 194, 196, 217-219, 246, 303, and 323 were
identified, and 16 new mutant forms of SauFDH were obtained and fully
characterized. Substitutions in positions 119 and 194 lead to an
increase of K . In the
Ile-Val-Ala-Gly line, position 119 tends to improve NAD
binding. K
of SauFDH V119G decreased by 27 times compared to the wild-type enzyme.
K Phe194Val decreased by 3.5
times. The catalytic constant for this mutant form practically did not
change. The use of a complex buffer increased the catalytic efficiency 6
times for the mutant with the Phe194Val substitution compared to
wt-SauFDH in a single-component buffer.
Optimizing UAV Computation Offloading via MEC with Deep Deterministic Policy Gradient
Authors: Hadi Muhammad Usman , Abbasi Ahmed Bashir
Published: May 2023

Mobile edge computing (MEC) seems to be highly efficient to process the
generated data from IoT devices by providing computational resources
locating in close range to network edge. MEC can be promising in
reduction of latency and consumption of energy from data transmissions
from offloading computational tasks from IoT devices to nearby edge
servers. In this paper, a computation offloading optimization algorithm
is proposed which is based on deep deterministic policy gradient for
realistic Aurelia X6 Pro unmanned aerial vehicle (UAV)-assisted MEC
systems. The proposed algorithm optimizes the offloading decision for
UAVs by taking task characteristics and the communication environment
into consideration. The simulation yields outcomes indicating that the
suggested algorithm can considerably enhance the competency of MEC
systems.
Spatial scale dependency of erosive runoff and sediment flow behavior on loessial slopes: an energy perspective
Authors: Wang Qingyuan , Letao Zhang , Wei Yiyuan , He Mengzhen , Zheng Zehao
Published: May 2023

Runoff erosion response associated with sediment transport as influenced
by erosive energy variability is a highly scale-dependent process. It is
of great significance to effectively identify the spatial scale effect
on erosive runoff energy for understanding the spatial pattern of
sediment flow behavior across various sites. To address this issue,
thresholds for erosive runoff were established based on frequency
analysis and four selected threshold parameters including runoff
duration ( T), stream power ( ω), stream energy factor (
SE) and area-specific sediment yield ( SSY). Based on
these thresholds, 77 erosive events were identified and separated from
non-erosive events for further analysis. The threshold for T was roughly
constant at hillslope but rapidly increased at entire slope. Thresholds
for ω and SE was linearly and positively related to the plot
area. A general increasing trend was observed in the threshold for
SSY from the upper hillslope to the entire slope. The sediment
delivery capacity of erosive runoff varied from 0.075 to 0.115 kg·m·J
, while the sediment increments capacity of erosive
runoff ranged from 0.43 to 4.47 kg·m ·W
. The sediment reduction benefit by regulation unit
stream energy factor varied from 5% to 65%. Overall, erosive runoff
events were characterized by longer runoff duration and larger erosive
energy, as well as greater sediment delivery capacity compared to
non-erosive events. Therefore, the runoff regulation on slopes should be
mainly orientated at the erosive energy control and the conversion of
slope runoff from erosivity to non-erosivity.
A 1/f noise optimized correlated multiple sampling technique for CMOS image sensor
Authors: yalei liu , Xu Jiangtao , Zha Wanbin , Nie Kaiming
Published: May 2023

Summary: This paper proposes a 1/f noise optimized correlated
multiple sampling (NOCMS) technique based on differentiated sampling
weights for CMOS image sensor. Transfer functions of standard CMS and
NOCMS for analyzing the suppression effect of random noise respectively
are derived based on the Fourier Transform theory. NOCMS shows a
dramatic advantage in the suppression of 1/f noise. For implementing
NOCMS, the ramp generator provides multiple sets of ramps with different
slopes to quantize the reset and signal voltages. Sampling weights are
increased with the decrease of ramp slopes. The last reset and first
signal values are weighted more due to their potentially higher
correlations. Simulation results under 110nm CMOS technology illustrate
that the ADC achieves DNL of −0.80/+0.70LSB and INL of −0.70/+0.90LSB
after the NOCMS operation. The input-referred random noise is 142.9µV
under standard CMS and 120.9µV
under NOCMS when the number of samples equals 8. The noise reduction
effect is improved by 15%. NOCMS makes it possible to further reduce
1/f noise of CMOS image sensor.

Published: May 2023

An emergency occurrence is an uncertain event, and the risk of losing a
single soul or life is a concern to many health managers and other
related healthcare agencies. Over the past few years, many health
concerns have focused on bridging the gap between patients and their
caregivers. In this regard, the research interest is to perform a
survival analysis of the sick and injured in the era of pre-hospital
care in the Upper East Region, and the method used was survival analysis
for the occurrence of life events. A total of four thousand, five
hundred and sixty-two (4,562) patients were involved, covering 18
operational months. The results showed that there was a higher
probability of a patient surviving within the first ten minutes than in
the last 30 minutes to an hour. The study found that an EMS-transported
patient has a 97.58% chance of surviving given that the incident has
not occurred beyond 10 minutes of onset and a 94.53% survival rate for
persons whose incident occurred between 30 and 60 minutes from the
onset, which is below the average survival rate of 94.98%. The Gamma
AFT model fits the survival dataset well and has better predictive power
than any other distribution under the AFT model. The study concludes
that the survival of pre-hospital patients is higher within the first 10
minutes, as are patient location, incident type, age of the patient, and
other factors that affect patient survival.
Overcoming the trade-off between early flowering and high yield in wheat: Light regimens, developmental dynamics, and transcriptome landscapes
Authors: Zhang Yinghua , Guo Xiaolei , Zhang Zhen , Li Junyan , Zhang Siqi , Sun Wan , Xiao Xuechen , Sun Zhencai , Xue Xuzhang , Wang Zhimin
Published: May 2023

Early flowering is a survival strategy in wheat ( Triticum
aestivum L.) that sacrifices grain yield under long photoperiod
conditions, and this contradiction is greatly affected by floral growth
and development. However, little is known about the regulatory
mechanisms that remove the barrier between “early flowering” and
“high yielding” during floret development. Here, we showed
high-resolution analyses of the number and morphology of floret
primordia and the transcriptomes of wheat spikes in three light
regimens. The development of all floret primordia in a spike could be
divided into four distinct stages: differentiation (Stage I),
differentiation and morphology development concurrently (Stage II),
morphology development (Stage III), and polarization (Stage IV).
Compared to the controls, the long photoperiod supplemented with red
light treatment shortened the time required to complete Stage I-II, then
improved assimilates in the spike and promoted anther development,
thereby increasing fertile floret primordia during Stage III, and
maintained fertile floret primordia development during Stage IV until
they became fertile florets (grains) via a dynamic gene network centered
on ubiquitin, calcium signaling, aldehyde dehydrogenase, zinc finger
proteins, and heat shock proteins. Our findings proposed a light
regimen, critical stages, and candidate regulators that promoted early
flowering and high yield in wheat.
Herbivory and allelopathy contribute jointly to the diversity-invasibility relationship
Authors: Jiang Wang , Gao Song , Hong He-fang , Xue Wei , Yuan Ji-wei , Wang Xiao-Yan , Kleunen Mark van , Li Junmin
Published: May 2023

Although herbivory and allelopathy play important roles in plant
invasions, their roles in mediating the effect of plant diversity on
invasion resistance remain unknown. We performed a two-year field
experiment in which we manipulated plant-species richness, herbivory and
allelopathy, and then experimentally invaded the plots with the invasive
Solidago canadensis. One year after the start of the experiment, there
was no significant effect of species richness on biomass of the invader,
as a negative indirect effect of species richness via increase light
interception was compensated by a positive direct effect. However, in
the second year, the relationship was negative, in line with the
diversity-invasibility hypothesis. The negative relationship was
strongest when herbivory and allelopathy were not manipulated.
Therefore, we conclude that joint effects of herbivory and allelopathic
interactions between the native plants and the invader play a major role
in the observed species richness-invasibility relationship.

attention is paid to the surfaces with singular points of the highest order.
Two classes of such surfaces, with one and two n?fold points, are discussed
in detail. We study their properties, give their algebraic equations and
visualize them with the program Mathematica.

Minimal 3-triangulations of p-toroids
Authors: Stojanovic Milica
Published: May 2023

It is known that we can always 3-triangulate (i.e. divide into tetrahedra
with the original vertices) convex polyhedra but not always non-convex ones.
Polyhedra topologically equivalent to ball with p handles, shortly
p-toroids, cannot be convex. So, it is interesting to investigate
possibilities and properties of their 3-triangulations. Here we study the
minimal number of necessary tetrahedra for the triangulation of a
3-triangulable p-toroid. For that purpose, we developed the concept of
piecewise convex polyhedron and that of its connection graph.

This paper is primarily devoted to studying (?, ?)-derivations of
finite-dimensional Lie superalgebras over an algebraically closed field F.
We research some properties of (?, ?)-derivations and the relationship
between the (?, ?)-derivations and other generalized derivations. Under
certain conditions, a left-multiplication structure concerned with (?,
?)-derivations can induces a left-symmetric superalgebra structure. Let L be
a Lie superalgebra, we give a subgroup G of Aut(L), exploiting fundamental
properties, we introduce and analyze their interiors, especially focusing on
the rationality of the corresponding Hilbert series when G is a cyclic
group.

pseudospectrum has no isolated points, has a finite number of connected
components and each component contains an element from the generalized
Drazin-meromorphic spectrum.

Novel flat-plate solar collector with an inclined N-S axis and relative E-W tracking absorbers and the numerical analysis of its potentials
Authors: Nesovic Aleksandar , Lukic Nebojsa , Josijevic Mladen , Jurisevic Nebojsa , Nikolic Novak
Published: May 2023

The current flat-plate solar collectors perform best when their absorbers rotate around their axis. However, with their concentrators, reflectors, and tracking mechanisms, they take up a lot of space and are thus commercially speaking, not the best solutions. This paper proposes a novel solar collector design which employs the (relative) rotation of absorbers, but strives to combine the benefits of fixed and (absolute) tracking solar systems, i.e. volume occupancy from the former and thermal performance from the latter. The findings of our numerical analysis show that, the solar irradiance efficiency of this novel design is 20% higher than that of a fixed flat-plate collector during clear-sky days, and it is equally lower than that of an absolute tracking collector. This paper also introduces a new criterion for describing single-axis tracking solar collectors which should be included in the classifications of solar collectors. Finally, the article, which represents a continuation of our research in the field of solar energy utilization, can contribute to the future development of solar technologies and solve some of the current challenges.
Is There an Optimal Time of Day for Exercise? A Commentary on When to Exercise for People Living With Type 1 or Type 2 Diabetes
Authors: Riddell Michael C. , Turner Lauren V. , Patton Susana R.
Published: May 2023

Exercise is a cornerstone of diabetes self-care because of its association with many health benefits. Several studies that have explored the best time of day to exercise to inform clinical recommendations have yielded mixed results. For example, for people with prediabetes or type 2 diabetes, there may be benefits to timing exercise to occur after meals, whereas people with type 1 diabetes may benefit from performing exercise earlier in the day. One common thread is the health benefits of consistent exercise, suggesting that the issue of exercise timing may be secondary to the goal of helping people with diabetes establish an exercise routine that best fits their life.
A High-Fat Diet Attenuates Amp-Activated Protein Kinase α1 in Adipocytes to Induce Exosome Shedding and Nonalcoholic Fatty Liver Development in Vivo

Published: May 2023

Exosomes are important for intercellular communication, but the role of exosomes
in the communication between adipose tissue (AT) and
the liver remains unknown. The aim of this study is to determine the
contribution of AT-derived exosomes in nonalcoholic fatty liver disease (NAFLD). Exosome components, liver fat content, and liver
function were monitored in AT in mice fed a high-fat
diet (HFD) or treated with metformin- or GW4869
and with AMP-activated protein kinase (AMPKα1) floxed (Prkaα1fl/fl/WT), Prkaα1-/-,
liver tissue-specific Prkaα1-/-, or AT-specific Prkaα1-/-
modification. In cultured adipocytes and white adipose tissue (WAT), the
absence of AMPKα1
increased exosome release and exosomal proteins by elevating tumor susceptibility gene 101 (TSG101)-mediated exosome biogenesis. In adipocytes treated with
palmitic acid, TSG101 facilitated scavenger receptor class B (CD36) sorting
into exosomes. CD36-containing exosomes were then endocytosed by hepatocytes to
induce lipid accumulation and inflammation. Consistently, an HFD induced more
severe lipid accumulation and cell death in Prkaα1-/-
and adipose tissue-specific Prkaα1-/- mice than in WT and
liver-specific Prkaα1-/- mice. AMPK activation by metformin
reduced adipocyte-mediated exosome release and mitigated fatty liver
development in WT and liver specific Prkaα1-/- mice.
Moreover, administration of the exosome inhibitor GW4869 blocked exosome
secretion and alleviated HFD-induced fatty livers in Prkaα1-/-
and adipocyte-specific Prkaα1-/- mice. We conclude that HFD-mediated
AMPKα1 inhibition promotes NAFLD by increasing numbers of AT CD36-containing exosomes.

Authors: Saputri Oktaviana , Sukartono
Published: May 2023

One of the central issues currently being discussed in the world of education is character education. Character education is experiencing disorientation, the fading of Pancasila values, and the shifting of life values as a result of globalization. This means that character education needs to be instilled from an early age, especially in elementary schools, one of which is independent character education. The aims of this study are to analyze the implementation of strengthening independent character education through "market day" for low grade students in elementary schools. This research uses descriptive qualitative research with a phenomenological research design. The research methods used are observation, interviews, and documentation. The validity of the data using triangulation of sources and techniques. Data analysis techniques include data collection, data reduction, data presentation, inference and verification. The results showed that in the market day program there were 3 stages, namely planning by holding monthly meetings by the school to form a market day management team, the implementation stage starting from students preparing goods stands, selling merchandise to bookkeeping and the evaluation stage once a week to monitor the development of student independence. The study used 5 independent indicators including doing their own work, taking initiative, not giving up, self-confidence and self-satisfaction, all indicators were fulfilled and indicated that the market day program was successful in being able to strengthen the independent character education of low-grade elementary school students in the very good category.

Published: May 2023

Vocational education has a duty to help green industries and sustainable development in society. However, learning in vocational education still has many shortcomings that must be overcome, given the contribution of a sizable negative impact on the environment. The implementation of green skills in learning is very important as an effort to overcome these problems. This study analyzes the perceptions of teachers and students as learning practitioners towards the implementation of green skills in the form of activity behavior in learning. Ten teachers and eight students were involved as key informants in collecting data through semi-structured interview techniques. Qualitative data were analyzed thematically with the help of NVivo 12 Plus Software. The findings in this study are classified into three main aspects, namely green skills planning activities, green behavior activities during learning, and green skills implementation evaluation. Planning activities related to the formulation of green competency outcomes, infrastructure needs and student readiness. As long as its implementation is oriented towards the behavior of reuse, reduce, repair and recycle. The impact of green behavior that is generated is about student learning comfort, energy-saving behavior and the ability to develop green products. The perceived evaluation is related to improving learning methodologies and building collaboration in class or collaboration with stakeholders, including the green industry, the local green environment service. Besides that, strengthening the competence of green skills-based learning management is very important to do.
The costs of inaction
Authors: Warren Christopher
Published: May 2023

Conserving can cut energy costs by up to 50%. Sustainable behaviour isn’t a financial hit you have to take in the name of a good cause. Be it water usage or equipment repair, inaction costs you a huge amount of money. Guests and staff alike want brands who share their values, and live them. Inaction costs you the loyalty of those you need most to succeed. From retention rates to user reviews, the doers become leaders. Sustainable hospitality earns the right to charge higher premiums. The numbers are in and guests will happily pay more for an incredible green experience. Those who choose inaction have no business charging more. Your local community benefits. Conserving is good for you, and it’s good for the causes you choose to support as well. Plus, guests love knowing they’ve been a part of it.
Step 2 Designing change in your accommodation (Materials)
Authors: Warren Christopher
Published: May 2023

Integrated thinking can transform your approach to problem solving. It is how to get the most out of your audits.  Be guest-centred. Step away from one-size-fits-all approaches to hospitality and really try to put yourself in your guests’ shoes. It is ultimately people who use resources, not buildings.  Call on altruistic values. People want to help. They also want to see the benefits for themselves. Where possible, design experiences that make green benefits immediate and clear.  Look at the big picture. Think holistically and embrace the complexities when they appear. It is an intimidating task, but the best solutions come when problems aren’t isolated from one another.  Iterate, iterate, iterate. There is no shame in not getting it perfect first time. Any plan worth its salt has a strong feedback loop, allowing you to refine designs over time.
Step 5 The eco feedback loop (Skill)
Authors: Warren Christopher
Published: May 2023

Feedback is all around us. Be it through apps, fitness bracelets, websites, or bills, your guests are already used to live, granular feedback. Many may even expect it. Who are you to let them down? Guests like being trusted. There is a hesitancy about giving guests and staff eco-feedback, but done artfully the process actually enriches the hospitality experience. It can give even the most casual getaway a sense of meaning and purpose. Embrace responsible technology. The most useful, actionable feedback is delivered quickly. Energy monitoring systems are vital tools, allowing you to identify areas for improvement quickly. Gamify! Feedback can and should be fun. Gamification – the tangible sense of progress and accomplishment – hugely boosts guest engagement with your conservation efforts. Put feedback in context. There is no one-size-fits-all answer to feedback. There are so many variables at play that you have to be able to step back and separate correlation from causation.
Step 4 Persuasion (Meaning)
Authors: Warren Christopher
Published: May 2023

How is it that some tourist accommodations are able to persuade guests to happily participate in their responsible tourism actions while other properties are not? Messages on their own do not always deliver the response you want, right? Often this is because we fail to recognise the importance of interpersonal persuasion. This could be by ignoring pre-suasion (gaining staff and guest support before requesting a specific action), or allowing a mismatch between messaging directed at guests and the reality they perceive in business operations and management. All these factors have to be aligned. Managers have asked me, is it the type of accommodation that matters or is it the type of guests? If your accommodation has no contact with guests, then the relationship can be purely an economic transaction. People also behave differently due to cultural reasons, or acclimatisation where it is a business or leisure-based property. So how can you maximise your persuasive potential despite these factors so that they do not hinder you, but actively support your sustainability initiatives?
The business case for guest participation
Authors: Warren Christopher
Published: May 2023

This book is a guide to achieving your most important sustainability initiative – achieving guest participation. Guests are key. They make the purchase decision and deliver revenue. They use most of the resources, contributing heavily to our environment footprint. They can act either responsibily or irresponsibly in what they see and do, and where they spend their money in the destination. A negative review can be very harmful to sales; their purchases during their stay can provide much needed additional revenue; and their return visits are very economic from a marketing sense. Yet until now, for some strange reason, we seem to have excluded them in our quest to become more sustainable. Let us address this key challenge now.

Neste texto, apresentam-se resultados de uma investigação qualitativa colaborativa, realizada em 2020 e 2021, em um grupo de professores sobre conhecimentos necessários ao docente que vai ensinar divisão de fração por fração no ensino fundamental. A metodologia utilizada foi a reflexão sobre a prática de seis professoras acerca de seus entendimentos e conhecimentos sobre o tema em encontros semanais do grupo. Traz um diálogo entre ensino e aprendizagem, ao buscar a compreensão do conceito e sua transposição didática, com base nas reflexões do grupo e no que pensam autores de educação matemática e à luz da filosofia. Discutem-se alternativas de algoritmos para o acesso ao conceito formal e a relevância deste, ao procurar o entendimento instrumental e relacional de uma tarefa. Uma das autoras tinha usado anteriormente com estudantes de pedagogia tal tarefa avaliativa em 2021. O estudo sugere ser possível ensinar este tema com compreensão, desde que o professor tenha objetivos claros, conhecimento conceitual e pedagógico de como ensinar fração e operações com frações. Ademais, recomenda que o professor considere os limites da contextualização, mas com a consciência de que a matemática não se produz em um vácuo. Enfim, mostra como um grupo de seis professoras refletiu sobre os próprios conhecimentos, quando evidenciaram potencialidades e fragilidades no ensino de tal tema..
A transição do aritmético ao algébrico no ensino da matemática no Colégio
Authors: Chevallard Yves , Almouloud Saddo Ag
Published: May 2023

Este artigo trata da transição do currículo aritmético para o algébrico. Tentaremos destacar, de forma específica e necessariamente limitada, a extensão da convulsão que os professores tiveram que enfrentar. Mas, acima de tudo, tentaremos mostrar como as modificações estruturais feitas na época no texto didático impõem seus efeitos até hoje, de uma forma muitas vezes escondida, mas muito real, apesar da "reforma da reforma" que os programas de 1978 deveriam simbolizar para a oitava série.
transição do aritmético ao algébrico no ensino da matemática no Colégio

O objetivo do artigo é discutir as dimensões epistemológicas e didáticas das reformas curriculares realizadas nos anos 60. Entre elas, a reforma Chevènement que visava o resgate do aritmético em detrimento do algébrico. Esse olhar para o numérico era visto como algo desestabilizador do currículo no sistema de ensino francês, no fim dos anos 1960. Essa reforma compreendia o numérico como algo prático e proveniente da realidade, que não necessitava de ideias tão abstratas, conforme exigia a álgebra. A reforma Chevènement relega os aspectos algébricos em segundo plano, mas não os exclui, e o uso das letras é visto como uma generalização precedente dos estudos dos cálculos numéricos. Revelam-se as problemáticas do ensino da aritmética e da álgebra no sistema de ensino francês que envolviam o processo de transposição didática estabelecido no programa oficial dos anos finais do ensino fundamental. A transposição didática, que modifica o funcionamento dos objetos do saber, imprime certa especificidade ao programa oficial que o ensino pródigo propõe ao aluno. Esse programa oficial engendra no aluno um programa pessoal que, conforme apresentado no programa oficial, desfrutará de uma adequação limitada como o referido objeto de saber, que deixará de ser uma aposta didática pura, será apenas uma ferramenta da atividade didático-matemática do aluno: por exemplo, a fatoração de uma expressão algébrica pode deixar de ser o objetivo de sua atividade, tornando-se o meio para resolver uma equação do terceiro grau, conhecendo-se uma de suas raízes.

Este artigo analisa a coerência entre objetivos e atividades propostas em planos de aula de Matemática para o Ciclo de Alfabetização. Reconhece-se o planejamento como um importante momento do trabalho pedagógico e como sendo capaz de moldar o currículo que será desenvolvido com os estudantes. O estudo é de origem qualitativa valendo-se do delineamento da pesquisa documental. Para tal, planos de aula, do período de ensino remoto, de professoras do Ciclo de Alfabetização foram analisados de modo descritivo no que tange aos objetivos anunciados e às atividades propostas. Foi possível concluir, neste estudo, que grande parte dos planos analisados não apresentava uma coerência entre o que diziam desenvolver nos objetivos, tal qual habilidades e como operacionalizam essas intenções nas atividades. Concluiu-se, portanto, que os currículos podem perder sua força, quando o planejamento se centra exclusivamente na execução de atividades.

Salah satu pembangunan jalan Tol di Pulau Sumatera ini adalah proyek pembangunan Jalan Tol Kayu Agung – Palembang – Betung (KAPB). Secara geografis sebagian besar wilayah kota Palembang memiliki kondisi tanah dominan rawa berair yang memiliki daya dukung rendah dan kedalaman tanah lunak yang sangat dalam. Terdapat beberapa lokasi yang selain karena faktor tingginya muka air, faktor kondisi tanah di area tersebut juga mempengaruhi pemilihan metoda yang tepat. Salah satu metoda yang digunakan untuk menanggulanginya adalah menggunakan konstruksi Pile Slab pada lokasi STA 6+020 s.d STA 6+695. Struktur  pada pile slab terdiri  dari full slab, pile  head dan tiang  pancang. Secara umum pemakaian pondasi tiang pancang dipergunakan apabila tanah dasar dibawah bangunan tersebut tidak mempunyai daya dukung yang cukup untuk memikul berat bangunan dan beban diatasnya, dan juga bila letak tanah keras yang memiliki daya dukung yang cukup untuk memikul berat dari beban bangunan diatasnya terletak pada posisi yang sangat dalam. Pemilihan metode pekerjaan pemancangan dapat dilakukan dengan berbagai metoda alternatif pilihan yang sudah biasa digunakan pada proyek – proyek sebelumnya. Termasuk pemilihan metode yang tepat untuk pekerjaan pemancangan darat hanya menggunakan crane service atau pemancangan rawa dengan menggunakan ponton yang menyesuaikan kondisi lapangan.Dikarenakan kondisi lapangan saat pekerjaan pemancangan air rawa mengalami penyurutan sehingga metode pemncangan darat + penimbunan lokasi rawa lebih efektif dari pada menggunakan pemancangan rawa dengan menggunakan ponton dan secara biaya juga lebih bagus dengan catatan (timbunan untuk pembuatan platform pemncangan darat diakui untuk pembayaran.

Air Minum merupakan kebutuhan dasar dan hak bagi semua warga negara yang menjadi kewajiban oleh pemerintah pusat maupun pemerintah daerah untuk memenuhinya. Dengan semakin meningkatnya jumlah penduduk maka kebutuhan akan air minum akan terus meningkat. Ketersediaan air minum merupakan salah satu tolok ukur kesejahteraan masyarakat serta mendorong produktivitas masyarakat dan pertumbuhan ekonomi. Untuk itu, penyediaan air minum menjadi aspek yang sangat penting dalam pengembangan ekonomi wilayah.

Kabupaten Mesuji memiliki potensi sumber daya air yang tinggi yang terdiri dari Sungai (Way) Mesuji dengan panjang 220 Km (di wilayah Kabupaten Mesuji-Tulang Bawang) dan daerah alir 2.053 Km2 . Sungai Mesuji bermuara di Laut Jawa dan membentang dari Timur ke Barat Provinsi Lampung yang sekaligus menjadi batas antara Provinsi Lampung dengan Provinsi Sumatera Selatan. Daerah aliran sungai ini memegang peranan penting dalam sistem hidrologi wilayah Kabupaten Mesuji dan sekitarnya yaitu sebagai daerah tangkapan air (catchment area) dari sungai-sungai besar dan hal ini dapat dimanfaatkan sebagai bahan baku  air minum untuk pengembangan SPAM.

Proses penyusunan rencana induk pengembangan sistem penyediaan air minum (RI-PSPAM) dalam upaya pengembangan SPAM adalah merupakan tahapan paling awal dari penyelenggaraan SPAM yang harus dilaksanakan dan disusun dengan benar sesuai dengan panduan, tata cara ataupun pedoman pada Lampiran 2I dari Peraturan Menteri Pekerjaan Umum Nomor 27 Tahun 2016 Tentang Penyelenggaraan Pengembangan Sistem Penyediaan Air Minum.

Keluaran yang diharapkan dari kegiatan ini adalah Rencana Induk Pengembangan SPAM Kabupaten Mesuji yang siap ditindaklanjuti oleh penyelenggara SPAM untuk menjadi dokumen Legal Pemerintah Kabupaten Mesuji mengenai Rencana Induk Pengembangan SPAM.

Berkembang pesatnya suatu wilayah perkotaan berdampak pula pada pengembangan fasilitas umum pada masyarakat kota tersebut. Kesehatan adalah keadaan sehat, baik secara fisik, mental, spiritual maupun sosial yang memungkinkan setiap orang untuk hidup produktif secara sosial dan ekonomis (Undang Undang Republik Indonesia No. 36 Tahun 2009). Pengembangan perkotaan sangat memerlukan pembangunan di segala bidang, diantaranya pembangunan bidang kesehatan. Pembangunan itu harus didukung oleh fasilitas dan sistem zonasi dan sirkulasi rumah sakit. Semakin berkembanganya kota Metro, maka kebutuhan fasilitas kesehatan juga akan meningkat. Rumah Sakit Mardi Waluyo saat ini perlu pengembangan sarana dan prasarana karena fasilitas yang ada saat ini kurang memadai terlebih bila diprediksikan peningkatan kebutuhan di masa mendatang. Sistem Zonasi dan Sirkulasi dalam bidang rumah sakit merupakan proses pengumpulan, pengelolahan, penyajian data kegiatan pelayanan, mobiditas/mortalitas, ketenagaan, data dasar dan peralatan rumah sakit baik dilakukan secara manual dan komputerisasi. Dengan tersedianya informasi bagi masyarakat umum, baik itu informasi fasilitas layanan, zonasi dan sirkulasi yang ideal di Rumah Sakit Mardi Waluyo dapat membantu pengembangan kota Metro dalam bidang layanan Kesehatan.

Daerah Irigasi Raman Utara dibangun tahun 1959 dengan rencana luas sawah baku 6.304 ha dan luas sawah fungsional sebesar 4.207 ha, yang sumber airnya berasal dari Way Raman serta mendapat suplesi dari Way Sekampung. Terdapat alur sungai kecil pada subdas di area saluran Primer Raman Utara yang diindikasikan memiliki akumulasi debit yang cukup besar dan mempengaruhi kekuatan tanggul irigasi BRU. 1b di STA 5,375, dilokasi ini terdapat box culvert yang melintang tegak lurus di bawah Saluran Primer Raman Utara namun tidak dapat mengalirkan air sungai/alur dengan debit besar karena memiliki kapasitas kecil dan kondisi yang tidak terpelihara, sehingga tanggul dan dinding penahan tanggul diatasnya terus terkikis serta mengurangi kekuatan tanggul Saluran Primer Irigasi Raman Utara. Kapasitas box culvert eksisting mempunyai kapasitas sebesar 16.145 m3/dt. Sedangkan berdasarkan perhitungan hidrologi debit banjir rancangan yang ada adalah 23,27 m3/dt, sehingga kapasitas eksisting tidak dapat menampung debit yang ada. Maka dari itu perlu peningkatan kapasitas dengan pilihan alternatif I dengan dimensi b = 3 m dan tinggi 3 m serta kemiringan saluran sebesar 0.001833 (beda elevasi 5.5 cm panjang saluran 30 m), yang dapat mengalirkan debit maksimal 26.975 m3/dt atau alternatif II dengan dimensi 2 kali lebar 2 meter dengan tinggi 2.5 meter yang dapat mengalirkan debit banjir sebesar 28.881 m3/dt.
