Kadri in zaposlovanje v času pandemije COVID-19
Authors: Novak Vesna
Published: February 2022

V prispevku proučujemo vpliv pandemije COVID-19 na kadre in stanje na trgu dela. Najprej opredelimo pojem kadri, ki se v slovenskem prostoru pogosto uporablja napačno in zato zamenjuje z nenatančnim ali celo nepravilnim obravnavanjem samega pojma. V nadaljevanju predstavimo različne možnosti proučevanja kadrov, bolj podrobno pa se omejimo na makrovidik proučevanja. Razpravljamo o krizi, ki jo je povzročila pandemija COVID-19 na zaposlenost in brezposelnost kadrov. Kljub dejstvu, da država s pravočasnimi ukrepi močno blaži posledice krize, pa podjetja težave rešujejo tudi z zmanjševanjem števila kadrov, predvsem tistih, ki delo opravljajo v nestandardnih oblikah dela. Posebno pozornost namenimo proučevanju zaposlenosti mladih, ki so v Sloveniji najbolj pogosto izpostavljeni začasnim oblikam dela, predvsem zaradi študentskega dela. V zaključnem delu razpravljamo o ukrepih, stanju in negotovostih, ki jih pandemija prinaša v našo družbo in delovno okolje.
Teoretične osnove kriz
Authors: Podbregar Iztok , Šprajc Polona
Published: February 2022

Krize so posledica pasivnega ali prepočasnega odzivanja na negotovosti, ki se v času hitrih sprememb nenapovedano pojavljajo v naključnih intervalih. Skupna značilnost je pomanjkanje časa in ostalih virov. Zavedanje oz. zaznavnje negotovosti narekuje tudi način poti iz neznane v znano situacijo in s tem napovemo globino krize. Percepcija negotovosti in posledično krizne situacije je pri udeležencih raznolika in je odvisna od kompetenc posameznika. Raznolikost percepcije in harmonizacija torej čas, potreben, da je percepcija udeleženih podobna, sta lahko vzrok za poglobljeno krizo oziroma ustvarjanje novih negotovosti in kriz. Na organizacijski ravni so zaznave kriz pri vodilnih zelo raznolike in se gibljejo na premici od zanikanja do hiperaktivnega nepremišljenega reagiranja. Največkrat vodstvo, ki je organizacijo pripeljalo v krizo, ni sposobno samostojno izvesti postopkov za izhod iz krize. Potrebno je uvesti vsaj zunanje svetovanje ali celo povsem novo vodstvo organizacije.

Authors:   BMSTU (Mytishchi branch), Makarenko A.V.
Published: February 2022

The method of designing variants of skidding trails nets is considered for cutting areas which has undeveloped areas (areas of young trees, swamps, territories of natural objects, etc.) when parameters are changed for slope angles of main and strip skid trails and the location of the loading point. An algorithm is developed and presented for allocation homogeneous areas where strip skidding trails are located parallel to each other and adjacent to one main skidding trail. To assess the effectiveness of variants of trail nets, the indicators were used by the average skidding distance and volume of cargo work, which are calculated directly on the basis of geometric characteristics for each of variants of trail nets. The calculation of the values of the efficiency indicators and the design of the trail nets is carried out by a developed computer program with a sequential change in the variable parameters. Graphs of the results are presented calculations of the average skidding distance and the volume of cargo work which depend on slope angles of the main skid trails and some values of the coordinates of the loading point. It was determined the ranges of variation of the efficiency parameters and the conditions under which they take the minimum values.

The study of the content and ratio of starch and fat in the shoots of the seed progeny of Siberian larch (Larix sibirica Ledeb.) shoots during its reintroduction to the Nizhny Novgorod region was carried out. The objects of the study were located in the arboretum of the Nizhny Novgorod State Agricultural Academy with geographical coordinates — 56°14'32,7"N 43°57'20,7"E and an absolute height — 178 m. The experimental site is assigned to the zone of coniferous-broad-leaved forests and is included in the area of coniferous-broad-leaved (mixed) forests of the European part of the Russian Federation. The work took into account the principle of the only logical difference, the representativeness of the samples, and the requirements for the typicality, suitability, and reliability of the experience. Ten accounting trees with modal development characteristics were examined in the field. From them, 10 normally developed shoots were harvested without signs of damage by external factors. To determine the content of spare substances, laboratory methods of histochemical analysis were used. Phenotypic differences between individuals of seed origin in the content and balance of spare substances were revealed. The highest content of starch and fat (19,20 ± 0,52 points) was observed in tree No. 2, and the lowest-in tree No. 4 (12,95 ± 0,37 points). The average value generalized for the entire data set was 15,88 ± 0,30 points. The hereditary conditionality of intraspecific variability of Siberian Larch for all tested characteristics of spare substances is established. The highest estimates of the heritability coefficient (64,12 ± 3,59 %) were observed for the total total content of starch and fat, the lowest (49,99 ± 5,00 %) — according to the estimates of the share of starch and the share of fat in the formation of their total stock. The conclusion is made about the control on the part of the genotype over the physiological state of Siberian larch trees of seed origin, and about their intraspecific polymorphism. The prospects of selection from their number of individuals whose physiological status most fully corresponds to the existing conditions of growth are proved.
Ohrid miner Cameraria ohridella Deschka & Dimic: features of invasive foci and perspectives of biological control
Authors:   BMSTU (Mytishchi branch), Bednova O.V.
Published: February 2022

The ecological mechanisms of one of the most dynamic biological invasions such as a colonization of artificial plantations of horse chestnut Aesculus hippocastanum L. by the ohrid miner, or chestnut miner Cameraria ohridella Deschka & Dimic (Lepidoptera, Gracillariidae) have been analyzed. The materials of publications on the bioecological features of C. ohridella in the conditions of native and invasive areas are summarized. The survey results of phytophage invasive foci in plantations of Moscow are presented. Particular attention is paid to the change in population characteristics (density, level of damage by entomophages) in connection with the biotopic conditions of horse chestnut plantations and meteorological features of the growing season. Measures to reduce the harm by C. ohridella by means of a biological control are considered. The information on the influence of various biotic factors on the phytophage is analyzed. Particular attention is paid to parasitoids as a means of the classical biological method. A suitable agent among parasitoids from natural foci of the miner has not yet been identified, and the level of local parasitism in European invasive foci is low. The perspective method of enhancing local parasitism through the accumulation and controlled release of parasitoids from leaf litter is substantiated. This technique makes it possible to synchronize the appearance of parasitoids with the phenology of the pest. This technology has already been tested by European researchers. Prospects are substantiated, the technology of seasonal colonization of parasits, which can be massively bred in biological laboratories such as parasitoids of Trichogramma (Hymenoptera, Chalcidoidea, Trichogrammatidae) and chrysopids (Neuroptera, Chrysopidae) is presented. Inside the invasive foci of C. ohridella, the effectiveness of seasonal colonization is proposed to be enhanced by using synthetic analogs of herbivore-induced plant volatiles (HIPV) that attract entomophages.

Strategie rozwoju i modele biznesowe największych grup stoczniowych produkujących okręty w Unii Europejskiej
Authors: Bieliński Jerzy , Bieliński Tomasz
Published: February 2022

Celem artykułu jest analiza strategii rozwoju i przyjętych modeli biznesowych w największych grupach kapitałowych zajmujących się budową i wyposażeniem okrętów w krajach Unii Europejskiej. Stwierdzono, że budowane okręty wojenne i ich wyposażenie stanowią największą część europejskiego przemysłu okrętowego. Przedmiotem oceny były brytyjska BAE Systems, francuska Naval Group, niemiecka TKMS, hiszpańska Navantia, SAAB Kockums w Szwecji, włoska Fincantieri oraz holenderski Damen.
Z analizy wynika, że jednym z podstawowych czynników kształtujących strategie rozwoju stoczni wojennych krajów UE jest polityka obronna i stworzone w ramach UE fundusze obronne. Zewnętrznymi czynnikami rozwoju jest także koniunktura na rynku statków wojennych. Czynniki te oraz przyjęte modele biznesowe znalazły swoje odzwierciedlenie w wielkości przychodów największych grup kapitałowych i marż zysku. Uzyskane dane wykazują na to, że kondycja finansowa tych firm nie jest stabilna. Modele biznesowe analizowanych przedsiębiorstw istotnie różnią się typami budowanych okrętów, strukturą własnościową i kapitałową. Wspólną cechą działania tych grup jest podejmowanie współpracy w realizacji projektów budowy okrętów w ramach UE oraz dążenie do konsolidowania tej produkcji w ramach dużych grup kapitałowych. Dynamika procesów konsolidacyjnych jest jednak stosunkowo niska i istnieje zagrożenie, że konkurencyjność stoczni wojennych może być niewystarczająca wobec agresywnych działań stoczni azjatyckich.
Wpływ turystyki na gospodarki krajów Andyjskiego Wspólnego Rynku (CAN)
Authors: Majcher Kamil
Published: February 2022

Celem artykułu jest ocena wpływu sektora turystycznego na gospodarki krajów członkowskich Andyjskiego Wspólnego Rynku – CAN (Kolumbia, Peru, Ekwador, Boliwia) w latach 2011–2019. W pracy wykorzystano metody badawcze w postaci analizy danych empirycznych udostępnionych przez krajowe i międzynarodowe jednostki badawcze, oraz analizy zależności – współczynnik korelacji liniowej Pearsona, współczynnik korelacji rang Spearmana.
Na podstawie przeprowadzonych badań można stwierdzić, że kraje CAN cechują się dynamicznym wzrostem wielkości ruchu turystycznego. Świadczy to o coraz większej atrakcyjności rynków CAN w skali międzynarodowej. Analiza zależności wskazuje jednak na to, iż wyłącznie w Ekwadorze i Boliwii zmiana wolumenu ruchu turystycznego jest silnie skorelowana z bezpośrednim zatrudnieniem w turystyce i bezpośrednim udziałem w krajowym PKB, przy czym najpopularniejsze destynacje turystyczne w CAN – Peru i Kolumbia nie wykazują silnego skorelowania z wybranymi zmiennymi, co potwierdzają estymowane współczynniki korelacji liniowej Pearsona i korelacji rang Spearmana.
Kobiety i kultura Śląska Cieszyńskiego na przykładzie Dory Kłuszyńskiej
Authors: Desperak Iza
Published: February 2022

Śląsk Cieszyński wyróżniał się na tle innych ziem będących pod zaborami rosyjskim czy pruskim. Wyróżniał się nie tylko rozwojem edukacji powszechnej, z której korzystały zarówno elity, jak i chłopskie dzieci. Charakterystyczną dla niego była również sprawa związana z pozycją kobiet. Kobiety bowiem były tam bardziej wyemancypowane i wykształcone niż w innych regionach ziem polskich. Panowała tam zasada, że w Radzie Narodowej Księstwa Cieszyńskiego (istniejącej od 1918 r.) na sześciu mężczyzn powoływano jedną kobietę. Jedną ze słynnych kobiet Śląskiego Cieszyna była m.in. Dora Kłuszyńska, działaczka socjalistyczna, feministyczna i narodowa.

The inclusion of job training and learning has recently been acknowledged as not only a key element of organizational initiatives to enhance learners' job readiness, but even as an organizational initiative to establish themselves in the marketable global education industry (Tran & Soejatminah, 2016). University students’ work-readiness continue to be a significant issue, with Mauritian industries lamenting a lack of soft skills and real-life experiences deemed necessary for recruitment. The University of Technology, Mauritius (UTM) has completely adopted the Work Placement principles since 2014 to extend numerous options to its learners to offer relevant work experiences. The present study aims at exploring the role of the Work Placement experience among the students studying at the UTM. A survey was conducted using an online questionnaire among 230 participants to measure soft-skill development. Before and after the internship, descriptive statistics such as means, standard deviations, and varying scores were investigated using SPSS. The results reveal that students have a positive attitude toward the acquired skills and abilities through Work Placement. The majority of the students asserted that through their Work Placement experiences, they have acquired important soft skills and have become excellent team players and good communicators

Osteoinduction Ability Of Human Adiposed Derived Mesenchymal Stem Cell (HADMSC) with Chitosan Scaffold Combination Towards Blood Serum Phosphorus Levels
Authors: Anjani Nindya Rizqi
Published: February 2022

Reconstruction of extensive bone tissue damage is a treatment with complication. Because moving the autologous tissue such as bone graft can cause complications that causes problems in the repair of extensive tissue damage so, the principle of tissue engineering (stem cells, bioreactor / growth factor, and scaffold) is used as an alternative to reconstruct damage to the tissue because it has many advantages. The combination of hADMSC and chitosan scaffold, is expected to trigger osteoinduction that can be expressed by osteogenic markers such as phosphorus levels in blood serum. To prove osteoinduction in a combination of Human Adiposed Derived Mesenchymal Stem Cell (hADMSC) and chitosan scaffold using blood serum phosphorus levels. This study used 12 groups with 5 sample each. Groups 1 to 4 were the negative control group at day 1,3,7, and 14. While groups 5 to 8 were the positive control group at day 1,3,7, and 14. Groups 9 to 12 were treatment groups at day 1,3,7, and 14. In the negative control group bone was only removed, in positive control group, bone was removed and chitosan scaffold was added, and in treatment group, bone was removed then, hADMSC and chitosan scaffold combination was added . Blood collection will be carried out in each group for examination of phosphorus levels in the blood serum. There were differences in phosphorus levels in blood serum in each group even though statistically there were only significant differences on day 14. The combination of hADMSC and chitosan scaffold caused a significant change in blood serum phosphorus levels on day 14 which means it triggers osteoinduction.

Mung bean (Vigna radiata) is grown throughout the world thanks to its short cycle, its great adaptability to climatic conditions and its good digestibility. In Burkina Faso, agriculture is faced with irregular rainfalls, resulting in water stress on plants causing growth and yields reduction. This study aims at identifying supplemental irrigation frequencies that help good mung bean plant to grow and yield. So, four watering schemes were applied to plants aged 26 days, grown in pots on a sandy and silty substrate, in natural conditions of light and temperature during the wet season. The watering regimes concerned a batch of plants watered only by rain (0 day scheme) and three other batches, each watered with tap water in the absence of rain respectively every 5 days, every 10 days and every 15 days. A completely randomized three-replicate block system was set up and agro-morphology parameters were measured. The study showed that the 5 days diet resulted in plants with better growth and good pod yields compared to other watering schemes. These results confirm that supplemental irrigation applied early during drought po0063kets is resilience to the irregularity of rains in the wet season, which is accentuated by climate change.

Synthetic technology application in the planting center of onion (Allium cepa L) Enrekang district, Indonesia, has passed the threshold recommendation dosage of manufacturer and agricultural extension. The synthetic fertilizer application with high dosage and inefficient nutrient absorption by plants is a problem that must be solved. So that, the proposed solution hypothesis is the application of biocompost enriched with Arbuscular Mycorrhizae (AM) as biological agents can reduce synthetic fertilizers use and absorption nutrients increase by plants. The aim of research to determine the growth of Allium cepa given dosage of biocompost enriched with AM, and research novelty are modification of innovation biocompost with AM as biological agent for growth of Allium cepa. The research was conducted for six months using model of Randomized Block Design. The treatment dosage of biocompost enriched with AM, are BM0 (control: Allium cepa planting method of local farmers); BM1 (Dosage of biocompost 100 kg.plot-1+ AM); and BM2 (Dosage of biocompost 200 kg.plot-1+AM), enrichment of biocompost with AM was carried out by mixing 2 kg of AM propagules for each treatment. The observed research variables are leaves number, root length, root diameter, root surface area, and tuber number. Observational data in the field and laboratory were analyzed using analysis of variance and Duncan's test. The results showed that the biocompost at a dose of 200 kg.plot-1 enriched with AM showed better growth in leaf number, root length, root diameter, root surface area, and the number of tubers compared to other treatments. So that the application of biocompost at a dose of 200 kg.plot-1 is the main finding in this study and can be recommended as a good dose for the production of Allium cepa which is environmentally friendly. This research supports sustainable and environmentally friendly agricultural systems which are the scope of healthy future agriculture.

Pain and Prescription Opioid Use Among US Construction Workers: Findings From the 2011‒2018 Medical Expenditure Panel Survey
Authors: Dong Xiuwen Sue , Brooks Raina D. , Rodman Christopher , Rinehart Richard , Brown Samantha
Published: February 2022

Objectives. To examine prescription opioid and nonopioid analgesic use among US construction workers and their associations with pain conditions and sociodemographic factors.

Methods. We analyzed data for about 9000 (weighted 11.5 million per year) construction workers who responded to the Medical Expenditure Panel Survey from 2011 to 2018. We applied both descriptive statistics and multiple logistic regression procedures in the analyses.

Results. An estimated 1.2 million (10.0%) of construction workers used prescription opioid analgesics annually. The adjusted odds of prescription opioid use were significantly higher for workers suffering from work-related injuries (adjusted odds ratio [AOR] = 3.82; 95% confidence interval [CI] = 2.72, 5.37), non‒work-related injuries (AOR = 3.37; 95% CI = 2.54, 4.46), and musculoskeletal disorders (AOR = 2.31; 95% CI = 1.80, 2.95) after we controlled for potential confounders. Adjusted odds of prescription opioid use were also higher among workers with poorer physical health (AOR = 1.95; 95% CI = 1.42, 2.69) or mental health disorders (AOR = 1.95; 95% CI = 1.41, 2.68).

Conclusions. Work- and non‒work-related injuries and musculoskeletal disorders significantly increased prescription opioid use among construction workers. To prevent opioid use disorders, multipronged strategies should be approached. (Am J Public Health. 2022;112(S1):S77–S87. https://doi.org/10.2105/AJPH.2021.306510 )

The ability to digitally count single molecules enables accurate and precise determination of the concentration of a disease biomarker. Owing to their intrinsic single-molecule sensitivity and fully electronic detection capability, solid-state nanopores show great promise for this task toward point-of-care diagnostic applications. Here, we describe the protocols for implementing a magnetic bead-based immunoassay strategy coupled with digital detection and downstream solid-state nanopore electrical readout. The digital scheme employs DNA nanostructures, as proxy labels for the presence (“1”) or absence (“0”) of the target protein. We provide step-by-step protocols for assembling and purifying DNA nanostructures; Preparing magnetic beads decorated with capture antibodies; Conjugating secondary detection antibodies to bind the DNA label; Functionalizing gold nanoparticles; and Running the full assay where thyroid stimulating hormone (TSH) from human serum samples is quantified down to the femtomolar range. The protocols and assay scheme presented herein are easily generalized to the quantification of a wide range of target proteins, by selecting the appropriate antibody pair.
Development of a kriging assessment framework and impact pathway for researching contamination with potentially toxic elements in urban landfill soil
Authors: Bakar Azizi Abu , Yoneda Minoru , Mahmood Noor Zalina
Published: February 2022

Landfill post-closure with contaminant concentration in soil below permissible limit assessed at limited spot does not represent the contamination issue. Therefore sizeable, qualitative, and cost-effective analysis of the concentrations of contaminants is needed and this work recommends kriging assessment and the logical impact pathway framework as factors of change in landfill aftercare management. The kriging framework is developed utilising lead (Pb) and chromium (Cr) data from inductively coupled plasma mass spectrometry (ICP-MS) analysis. The development of the kriging framework is conducted based on the observation of censored data from ICP-MS analysis. The estimation analysis involves the analysis of ordinary kriging with regression analysis, showing the interpolation of spatial correlation and regression error. Hence, ordinary kriging with regression of the variable of interest, i.e., Pb, using the data of the explanatory variable, i.e., Cr, is inappropriate. Further investigation with the utilisation of guess-field kriging analysis hypothetically exposed a potential contaminated area using an existing but limited number of explanatory variables; although, guess-field kriging may possibly result immense uncertainty at the area where the explanatory variable does not exist. Besides, this work anticipated outcomes in societal impact and sustainability practices from the proposed kriging framework by recommending a logical impact pathway. The development of the kriging framework and impact pathway reassure the necessary actions to be executed by responsible parties and act as the stimulus of a wider spectrum of improvement initiatives to oversee real issues, such as the time of occurrence, and to prevent negative impacts on the environment and humans.
How do trial teams plan for retention during the design stage of the trial? A scoping review protocol.
Authors: Murphy Ellen , Gillies Katie , Shiely Frances
Published: February 2022

Background Retention remains a major challenge for many clinical trials. The SPIRIT guidelines state the following information on retention should be included in the trial protocol “Plans to promote participant retention and complete follow up including list of any outcome data to be collected for participants who discontinue or deviate from intervention protocols”. This guidance shows the importance of planning retention methods and handling missing data as this can impact how the results of the trial are analysed and interpreted. The most recent Cochrane review of strategies to improve retention in clinical trials highlighted that some trials implemented multiple retention strategies and we questioned whether the use of multiple strategies was planned at the design stage and included in the protocol or are strategies implemented when retention becomes an issue within the trial. The purpose of our scoping review is to establish how trial teams prepare for retention at the design phase of clinical trials. Methods and analysis We will follow the methodological framework and guidelines for scoping reviews outlined by the Joanna Briggs Institute. We will search MEDLINE/PubMed, Scopus, EMBASE, CINAHL (EBSCO) and Web of Science. A comprehensive search strategy for PubMed was developed in collaboration with an experienced research librarian and the search will be adapted to each database. The screening process will involve two reviewers. EM will independently screen all titles, abstracts, and where necessary full protocol texts to determine eligibility. FS will screen 10% of the overall search output. We may purposively sample eligible protocols to ensure the protocols represent a variety of trial and intervention types. Next, data will be extracted from each protocol using the data extraction form. Once the data has been extracted the results will be synthesized. The analysis will be qualitative using a narrative summary and descriptive statistics where appropriate. DiscussionThe scoping review will help trial methodologists better understand when/if retention strategies are planned for during the design stage of the trial contributing to the PRioRiTy II unanswered question “How should people who run trial plan for retention during their funding application and creation of the trial (protocol development)?”.
A Case Study of Two Failures of a High Cut-slope in the Northeastern Area of Sichuan, China

A high cut-slope in the northeast of Sichuan Province, China failed after excavation followed by rainfall. A second slope failure occurred under heavy rainfall a few days after being reinforced with anchor cables and grid beams. In this study, the detailed information and the failure history of the cut-slope were first presented. A series of numerical simulations were then conducted using finite element method (FEM) to analyze the slope stability and explore the failure mechanism. The numerical analyses found that the slope failures should not be simply attributed to rainfall. Other lessons have been learned from these two failures. They are: mis-characterization of the geological and hydraulic conditions of the site, poor understanding of the reaction of strongly weathered argillaceous shale materials with weak interlayers to water, and failing to implement proper drainage system in the slope after placing shotcrete on the slope surface. These resulted in the wrong measures to protect the cut-slope and the improper remediation works to stabilize the failed slope. The bond section of the anchor cable should be installed in the moderately weathered rock layer rather than strongly weathered layer with weak planes. The multiple failures of the slope warned all the parties that proper understanding of the geological and hydrological conditions of the site and the material properties is the starting point of any design and construction works.

A study was conducted to investigate the effects of free-range, part-time free range, and confinement rearing systems on growth performance and slaughter traits in Lakha, Mushki, Peshawari, and Sindhi Aseel for 10-week duration (7-16 week). In total, 216 Aseel cockerels (6-wk-old), 54 from each variety, were allotted to 12 experimental groups, in a 3 × 4 (rearing system × Aseel variety) factorial arrangement under a randomized complete block design, replicated 3 times with 6 birds in each. Final body weight, weight gain, folds of increase, and mortality parameters of growth performance and carcass yield, breast, thigh, drumstick, wing, liver, gizzard, and heart parameters of slaughter traits were evaluated. Data were analyzed by using 2-way ANOVA under factorial arrangement. The results indicated increased body weight gain, folds of increase, breast and drumstick in both confinement and part-time free range (P<0.05), whereas enhanced body weight, dressing, thigh, liver, and gizzard only in confinement rearing system. Among the Aseel varieties, Sindhi showed enhanced final body weight, weight gain, thigh and drumstick yields, whereas breast and gizzard weights were found to be greater in Lakha and Sindhi. Carcass yield, however, remained higher in all varieties except Peshawari. In conclusion, indoor rearing system had positive effects on growth and carcass-related parameters. Among the varieties, Sindhi showed better growth and slaughter-related performance traits in alternative rearing systems and hence, can be used as slower growing meat chicken in the aforesaid systems of poultry production in developing countries for better livelihood.

Published: February 2022

In this paper, the concept of photonic crystals (PhCs) is fundamental to the design and simulation of an all-optical device. The proposed logic device is composed of two-dimensional (2D) photonic crystal waveguides with a central photonic crystal ring resonator (PCRR). The new all-optical NAND logic gate is composed of two linear waveguides coupled to each other through a single compact PCRR. The plane wave expansion (PWE) and finite-difference time-domain (FDTD) methods are used to analyze the behavior of the structure that is implemented on the operational wavelength of 1700 nm on an air wafer of only 12 µm × 12 µm. The simulation results show that the proposed all-optical NAND gate is a strong candidate to be used for ultrafast photonic integrated circuits (PICs) being highly advantageous with high transmitting power, simple design and without use of the optical amplifiers and nonlinear materials.
