Published: November 2021

Dada à crescente demanda de atividades exercidas pelo(a) Secretário(a) Executivo(a), atuante como cogestor de seus assessorados no atual cenário corporativo, é natural que muitos profissionais da área absorvam funções de cunho gerencial, dentre as quais cita-se a gestão de projetos. Para tal, é necessário que o Secretário(a) Executivo(a), além de outras capacidades, desenvolva e mobilize competências intraempreendedoras. Diante desse contexto, a presente pesquisa tem como objetivo verificar quais fatores levam profissionais de secretariado executivo a propor um projeto e, como consequência, tornarem-se responsáveis pela sua gestão na empresa em que atuam. Para contemplar tal estudo, como metodologia, foram empreendidas pesquisas bibliográficas, bem como coleta de dados a partir de entrevistas realizadas com profissionais da área secretarial que idealizaram e geriram projetos em suas organizações. Como resultado, verificou-se que os fatores motivacionais, ou seja, os fatores intrínsecos têm uma maior preponderância em relação aos fatores higiênicos (extrínsecos). Ademais, constatou-se que as competências necessárias à atuação secretarial são compatíveis com o perfil de um gestor de projetos.

ABSTRACT
Given the increasing demand of activities performed by the Executive Secretary, who is working as co-manager of your advisors in the corporate setting, it is notorious that many professionals in the area develop managerial functions, which project management can be mentioned. For this purpose, it is necessary that the Executive Secretary, in addition to other capabilities, develop and mobilize intrapreneurial competencies. In this context, this research aims to verify which factors lead secretarial professionals to proposing and managing a project and, as a result, become responsible for management in the company where they work. To behold this research, as methodology, it was applied bibliographic research, as well as data collection from interviews conducted with secretarial professionals who conceived and managed projects in your organizations. As a result, motivational factors (intrinsic factors) have a greater predominance in relation to hygienic factors (extrinsic). Furthermore, the necessary competencies required for the secretarial work are compatible with the profile of a project manager.

Authors: Al-Ghazali Ameen Saif Ali 
Published: November 2021

The subject of the research is cross-country comparisons of models of organizational and economic mechanism of regulation (OEMR) of processes of production of fundamental scientific knowledge (FSK) during the organization of basic scientific research (FSR) by academic institutions. The ultimate goal of the development of OEMR and the task of conducting FSR is formulated. The hypothesis about the possibility of effective implementation of OEMR FSR in the case of clear definition of subjects and forms of regulation is substantiated. The thesis on the expediency of structuring OEMR FSR with the separation of levels of systematization of scientific knowledge as an object of regulation, conceptual components, subject content of FSK subsystems, elements of the FSK formation cycle in the process of solving partial cognitive problems of fundamental scientific theories (FNT), functional levels principles and criteria for ensuring the effectiveness of non-monotonic abductive FSR, distinguishing tools for providing analytical and regulatory functions.
The research method is to generalize the features of national models of public regulation of FSR, which differ in proportions and combination of methods of direct administration and create conditions for independent choice of subjects of directions and options of R&D under the influence of dynamic updating of axiological concept of FSR. There are methods of using power competencies to form and use basic research competencies of FSR subjects in the field of FSR production – direct administrative influence, formal-mechanistic solidarity of subjects within the functioning of academic research networks, external value orientation and motivation of FSR subjects. The list of methods of stimulating innovative renewal of practical and transformative competencies in the field of FSK functioning includes methods of indirect regulatory influence, contractual solidarity of FSR subjects within the functioning of voluntary/temporary professional research networks, internal value and identification orientation of FSR subjects, global standards of practical and transformative competencies of FSR subjects in the field of FSK formation.
The result of the study is to identify the main types of models with a detailed description of the practical principles of the implementation of FSR in the countries that represent them. The difference in the potential of FSR implementation depends on the ability of national institutions to organize the processes of conducting cyclical program research in order to increase the background design knowledge of the most universal nature.

The Stoat occupies a wide range of habitats. It is often found in successional or forest-edge habitats, in the scrub, alpine meadows, marshes, riparian woodlands, hedgerows, and riverbanks that have high densities of small mammals, especially Microtus and Arvicola voles (KİNG, 1983). PULLİAİNEN, (1999) stated that coniferous and mixed woodlands are preferred, but that many other habitats are used including tundra and the summits of fells and mountains. Dense forests and deserts are avoided (KİNG, 1983). Although mentioned in all to-day's Laws on Hunting (1893 – 2014) in Bosnia-Herzegovina, there are not so many records of this species or official reports in hunting bag. Considering its geographic range (IUCN 2020), in Bosnia-Herzegovina, the stoat is recorded only in the western and northern parts of the country. İn this paper, we presented new localities where the stoat was observed in Bosnia-Herzegovina, as well as types of habitats where it was recorded.

Published: November 2021

The structure and construction of ships made of aluminum alloy, generally of the type of wrought aluminum alloy, when experiencing fatigue failure caused by cracking of the ship structure, is a serious problem. Judging from the ‘weaknesses’ of aluminum material for ships, this chapter will explain the use of alternative materials for ship building, namely aluminum-based composite material which is an aluminum alloy AlSi10Mg (b) ship building material based on the European Nation (EN) Aluminum Casting (AC) - 43,100, with silicon carbide (SiC) reinforcement which has been treated with an optimum composition of 15%, so that the composite material is written with EN AC-43100 (AlSi10Mg (b) + SiC * / 15p. Composite ship model using ANSYS (ANalysis SYStem) software to determine the distribution of stress. The overall result of the voltage distribution has a value that does not exceed the allowable stress (sigma 0.2) and has a factor of safety above the minimum allowable limit, so it is safe to use. The reduction in plate thickness on the EN AC-43100 (AlSi10Mg (b)) + SiC * /15p composite vessel is significant enough to reduce the ship’s weight, so it will increase the speed of the ship.

Elaeis guineensis is an alternative source of raw materials for renewable energy in Malaysia. Thus, to enhance the use of the abundant biomass generated by the oil palm industry in Malaysia, a study was conducted in view of exploring the chemical composition such as sugar potential of this industrial byproduct. In this context, oil palm trunks were separated into individual cell that are parenchyma and vascular bundle to investigate the fundamental research about oil palm trunk. The aim of this study was to examine the chemical composition of parenchyma and vascular bundle of oil palm trunk. The oil palm trunk was kept under shade at room temperature of 28–30°C for 0, 45, and 60 days. The chemical composition analysis was carried out according to TAPPI methods. Based on storage time and different part of oil palm trunk, the result has shown that the sugar content was higher in parenchyma compared to vascular bundle and increase at the storage time of 0, 45, and 60 days while amount of starch showed decrease at the same storage time. It shows that conversion or fermentation of starch to sugar occur in oil palm trunk during storage times of 0, 45, and 60 days, respectively.

Authors: Adnan Islam Rashed 
Published: November 2021

In this chapter, the piezoelectric and magnetoelectric properties of Pb (Zr0.52T0.48)O3–X NiFe1.9Mn0.1O4 (PZT-NFM, where X ranges from 3 to 10%) were investigated along with SEM and TEM analysis. Post sintering thermal treatment (annealing and aging) was introduced to enhance the piezoelectric and magnetoelectric property of the composites. The density was found around 7.6–7.8 gm/cc. The piezoelectric constant d33 and the voltage constant were found to be decreased with increasing magnetic particle from 3–10%. Experimental results indicated that the magnetoelectric voltage coefficient (dE/dH) increases with increasing percentage of Nickel Ferrite (~35 for 3% NF to 140 mV/Oe. cm for 10% NF at 1125°C). The samples, which were annealed and aged after sintering show as high as 50% (140 to 220 mV/cm Oe) increase in dE/dH coefficient. This is due to the increase in resistivity due to better homogeneity. The H-M curve of the composite powders show that the PZT-NFM is a ferromagnetic material as well. The SEM investigation shows very compact structure with average grain size around 150 nm and some areas of the NF rich phase. The X-ray mapping shows that the NF is distributed in the big grains of the matrix and after annealing it homogenizes.
Treatment of Cutaneous Squamous Cell Carcinoma with Immune Checkpoint Inhibitors in Special Populations
Authors: Bossi Paolo , Lorini Luigi 
Published: November 2021

Cutaneous squamous cell carcinoma (cSCC) may develop in patients with dysregulated immune activation (pre-existing autoimmune diseases or immunosuppression due to hematopoietic/solid organ transplant recipients), patients with a compromised immune function (long-term immunosuppression), and patients carrying chronic viral infections, or those affected by lymphoproliferative diseases. It should be also considered that patients presenting with immunosuppression have a high incidence of cSCC (65–250-times higher than general population), highlighting the central role played by the immune system in the development of cSCC. All these cases must be considered as “special populations” for treatment with immune checkpoint inhibitors (ICIs), as the safety and activity of these drugs have not been studied on these specific cases, since these patients were excluded from clinical trials leading to approval of ICIs. It is therefore important to gain as much information as possible from the analysis of real-life data, to derive an indication to be adopted in everyday clinical setting. Moreover, therapeutic alternatives other than ICIs are scarce, mainly consisting in chemotherapy and anti-EGFR agents, whose activity is lower than immunotherapy and whose toxicity (particularly with chemotherapy) are not sustainable by this frail population. Here, we describe the current evidence of treatment with ICIs in special populations and conclude that it is necessary to find a balance between treatment risks (toxicities) and benefits (efficacy), as well as engaging a multidisciplinary team of experts to thoroughly manage and treat these patients.

Background
The application of otolith-based tools to inform the management and conservation of fishes first requires taxon- and stage-specific validation. The Delta Smelt (Hypomesus transpacificus), a critically endangered estuarine fish that is endemic to the upper San Francisco Estuary (SFE), California, United States, serves as a key indicator species in the SFE; thus, understanding this species’ vital rates and population dynamics is valuable for assessing the overall health of the estuary. Otolith-based tools have been developed and applied across multiple life stages of Delta Smelt to reconstruct age structure, growth, phenology, and migration. However, key methodological assumptions have yet to be validated, thus limiting confidence in otolith-derived metrics that are important for informing major water management decisions in the SFE.

Methods
Using known-age cultured Delta Smelt and multiple independent otolith analysts, we examined otolith formation, otolith-somatic proportionality, aging accuracy and precision, left-right symmetry, and the effects of image magnification for larval, juvenile, and adult Delta Smelt.

Results
Overall, otolith size varied linearly with fish size (from 10–60 mm), explaining 99% of the variation in fish length, despite a unique slope for larvae < 10 mm. Otolith-somatic proportionality was similar among wild and cultured specimens. Aging precision among independent analysts was 98% and aging accuracy relative to known ages was 96%, with age estimates exhibiting negligible differences among left and right otoliths. Though error generally increased with age, percent error decreased from 0–30 days-post-hatch, with precision remaining relatively high (≥ 95%) thereafter. Increased magnification (400×) further improved aging accuracy for the oldest, slowest-growing individuals. Together, these results indicate that otolith-based techniques provide reliable age and growth reconstructions for larval, juvenile, and adult Delta Smelt. Such experimental assessments across multiple developmental stages are key steps toward assessing confidence in otolith-derived metrics that are often used to assess the dynamics of wild fish populations.
Adaptive attitude control for spacecraft systems with sensor and actuator attacks
Authors: Sun Haibin , Hou Linlin 
Published: November 2021

SummaryThis paper is addressed with the attitude stabilization problem for spacecraft systems with external disturbances in physical layer and sensor and actuator attacks (SAAs) in cyber layer. Some state‐dependent attacks are implanted in system measurement data channels and control input commands. Two stable adaptive backstepping controllers are constructed for two different assumption conditions with sensor attack, in which a compensation term in each controller is included to eliminate the effects of SAAs and recover the ideal system performance. Under the proposed control schemes, the system states can asymptotically converge to zero even if SAAs and external disturbances are co‐existing. The validity of the developed scheme is demonstrated via a simulation example.

AbstractAs the primary malignant tumor in the brain, glioblastoma exhibits a high mortality due to the challenges for complete treatment by conventional therapeutic methods. It is of great importance to develop innovative therapeutic agents and methods for treatment of glioblastoma. In this work, the imaging and therapy of glioblastoma are reported by using dye sensitized core‐shell NaYF4:Yb/Tm@NaYF4:Nd nanoparticles with strong up/down‐conversion luminescence, of which the ultraviolet up‐conversion emissions at 348 and 365 nm are significantly enhanced by nearly 28 times and used to control the release of SO2 from 5‐Amino‐1,3‐dihydrobenzo[c]thiophene 2,2‐dioxide prodrug for gas therapy, and the second near‐infrared (NIR‐II) down conversion emission at 1340 nm is increased five times and applied for imaging. It is revealed that the released SO2 molecules not only cause oxidative stress damage of tumor cells, but also induce their pro‐death autophagy by down‐regulating the expression of p62 and up‐regulating the ratio of LC3‐II/LC3‐I, ultimately inhibiting tumor growth. The work demonstrates the great potential of rare earth nano‐platform with functions of NIR‐II imaging and photo‐controlled gas therapy in the diagnosis and treatment of orthotopic glioblastoma.

Published: November 2021

AbstractAcoustofluidics has emerged as a promising method for submicron particle manipulation. However, ultrahigh‐frequency or focused sound waves are usually required to generate sufficient acoustic radiation force or localized streaming vortex for trapping nanoscale objects, which is more challenging in device fabrication. This work presents a novel method using a low‐frequency acoustic field actuated micro‐pillar array (APA) chip to efficiently enable programmable and parallel trapping of nanoparticles. Driven by the acoustic waves, each arrayed vibrating micropillar generates a highly localized acoustic field with enhanced acoustic radiation forces and well‐confined vortex streaming around the pillar. The APA chip is demonstrated with geometric tuning ability of regulating the trapping limit by altering the pillar size. Micropillar arrays with a diameter of 5 µm are demonstrated to trap 112 nm particles efficiently. Thanks to the convenience of using ultrasounds and arraying micropillars of different geometric sizes, the APA chip provides an alternative of submicron particle manipulation technique for programmable and high‐throughput trapping and patterning of particles, with potential for “lab‐on‐a‐chip” sample preparations.
Winter crop effect on soybean production in the Southeast United States

Published: November 2021

AbstractVarious winter crops can be produced before soybean [Glycine max (L.) Merr] in the Southeast United States, however the effect of these winter crops on soybean productivity and the optimum maturity group to use following various winter crops remains unknown. This experiment was conducted in five environments across North Carolina in 2019 and 2020 to understand the effect of winter crop and soybean maturity group (MG) on soybean productivity. Winter crops investigated included cereal rye (Secale cereale L.) as cover crop, cereal rye–crimson clover (Trifolium incarnatum L.) as cover crop mixture, May fallow, wheat (Triticum aestivum L.) for grain, rapeseed (Brassica napus L.) for grain, and June fallow. Three soybean cultivars (MGs III, V, and VII) were evaluated following each winter crop. Data collected were cover crop/residue biomass, winter crop grain yields, soybean stand, soil moisture, soil temperature, soybean chlorophyll content, and soybean yield. Across environments, winter crop did not affect soybean yield despite differences in soybean stand, soil moisture, soil temperature, and soybean chlorophyll content following various winter crops. The results indicate that across the environments evaluated in this experiment, factors such as soybean stand, soil moisture, or N availability were not limiting factors for soybean productivity and that soybean yield response is relatively insensitive to previous crops. Across winter crops, greater yields typically were achieved with a MGs V and VII cultivar than with a MG III cultivar. Results from this experiment demonstrate that the insensitivity of soybean yield to the previous crop allows for flexibility incorporating soybean into rotations and that regardless of the previous winter crop, yield is typically optimized with a MG V cultivar or later when standard management practices are employed.
