Moist moss tundra on Kapp Linne, Svalbard is a net source of CO2 and CH4 to the atmosphere
Authors: Lindroth Anders , Pirk Norbert , Jónsdóttir Ingibjörg S. , Stiegler Christian , Klemedtsson Leif , Nilsson Mats
Published: December 2021

Abstract. We measured CO2 and CH4 fluxes using chambers and eddy covariance (only CO2) from a moist moss tundra in Svalbard. The average net ecosystem exchange (NEE) during the summer (June–August) was −0.40 g C m−2 day−1 or −37 g C m−2 for the whole summer. Including spring and autumn periods the NEE was reduced to −6.8 g C m−2 and the annual NEE became positive, 24.7 gC m−2 due to the losses during the winter. The CH4 flux during the summer period showed a large spatial and temporal variability. The mean value of all 214 samples was 0.000511 ± 0.000315 µmol m−2s−1 which corresponds to a growing season estimate of 0.04 to 0.16 g CH4 m−2. We find that this moss tundra emits about 94–100 g CO2-equivalents m−2 yr−1 of which CH4 is responsible for 3.5–9.3 % using GWP100 of 27.9 respectively GWP20. Air temperature, soil moisture and greenness index contributed significantly to explain the variation in ecosystem respiration (Reco) while active layer depth, soil moisture and greenness index were the variables that best explained CH4 emissions. Estimate of temperature sensitivity of Reco and gross primary productivity showed that a modest increase in air temperature of 1 degree did not significantly change the NEE during the growing season but that the annual NEE would be even more positive adding another 8.5 g C m−2 to the atmosphere. We tentatively suggest that the warming of the Arctic that has already taken place is partly responsible for the fact that the moist moss tundra now is a source of CO2 to the atmosphere.
SELF v1.0: a minimal physical model for predicting time of freeze-up in lakes
Authors: Toffolon Marco , Cortese Luca , Bouffard Damien
Published: December 2021

Abstract. Predicting the freezing time in lakes is achieved by means of complex mechanistic models or by simplified statistical regressions considering
integral quantities. Here, we propose a minimal model (SELF) built on sound physical grounds that focuses on the pre-freezing period that goes from mixed conditions (lake temperature at 4 ∘C) to the formation of ice (0 ∘C at the
surface) in
dimictic lakes. The model is based on the energy balance involving the two main processes governing the inverse stratification dynamics: cooling of water
due to heat loss and wind-driven mixing of the surface layer. They play opposite roles in determining the time required for ice formation and
contribute to the large interannual variability observed in ice phenology. More intense cooling does indeed accelerate the rate of decrease of lake
surface water temperature (LSWT), while stronger wind deepens the surface layer, increasing the heat capacity and thus reducing the rate of decrease
of LSWT. A statistical characterization of the process is obtained with a Monte Carlo simulation considering random sequences of the energy
fluxes. The results, interpreted through an approximate analytical solution of the minimal model, elucidate the general tendency of the system,
suggesting a power law dependence of the pre-freezing duration on the energy fluxes. This simple yet physically based model is characterized by a
single calibration parameter, the efficiency of the wind energy transfer to the change of potential energy in the lake. Thus, SELF can be used as a
prognostic tool for the phenology of lake freezing.

Abstract. Quantitative satellite observations only provide an assessment of ice sheet mass loss over the last four decades. To assess long-term drivers of ice sheet change, geological records are needed. Here we present the first millennial-scale reconstruction of David Glacier, the largest East Antarctic outlet glacier in Victoria Land. To reconstruct changes in ice thickness, we use surface exposure ages of glacial erratics deposited on nunataks adjacent to fast-flowing sections of David Glacier. We then use numerical modelling experiments to determine the drivers of glacial thinning. Thinning profiles derived from 45 10Be and 3He surface exposure ages show David Glacier experienced rapid thinning of up to 2 m/yr during the mid-Holocene (∼ 6.5 ka). Thinning slowed at 6 ka, suggesting the initial formation of the Drygalski Ice Tongue at this time. Our work, along with ice thinning records from adjacent glaciers, shows simultaneous glacier thinning in this sector of the Transantarctic Mountains occurred 4–7 kyr after the peak period of ice thinning indicated in a suite of published ice sheet models. The timing and rapidity of the reconstructed thinning at David Glacier is similar to reconstructions in the Amundsen and Weddell embayments. To identify the drivers of glacier thinning along the David Glacier, we use a glacier flowline model designed for calving glaciers and compare modelled results against our geological data. We show that glacier thinning and marine-based grounding-line retreat are controlled by either enhanced sub-ice-shelf melting, reduced lateral buttressing or a combination of the two, leading to marine ice sheet instability. Such rapid glacier thinning events during the mid-Holocene are not fully captured in continental- or catchment-scale numerical modelling reconstructions. Together, our chronology and modelling identify and constrain the drivers of a ∼ 2000-year period of dynamic glacier thinning in the recent geological past.

Published: December 2021

The objective of the research is to evaluate the quality of harvesting oil palm fresh fruit bunches (FFB) correlated to the harvest system implemented by two afdelings in the oil palm plantation company, PT. Sentosa Kalimantan Jaya. The research employs descriptive design, with qualitative approach, purposive sampling and snowball sampling using questionnaires, and documentation. The research reveals that the characteristics of harvesters from two afdelings are dominated from the productive age and educated at elementary school. The harvesters in afdeling 2 have more experience than afdeling 4. Afdeling 2 provides better quality of FFB than afdeling 4, it comprises ripe fruit was 86.91%, abnormal was 1.07% and long stalk was 0%. Meanwhile, afdeling 4 comprises raw fruit was 1.32%, ripe fruit was 79.97%, and over ripe fruit was 12.88%. Both afdelings have permanent design of harvest system comprise the percentage of loose fruit, sengkleh stems, under pruning and over pruning which are beneath the standard. The under pruning interferes the process of cutting fruit, meanwhile the over pruning would potentially be able to reduce average bunches weight and produce male flowers dominantly. As a result, it can be deduced that the main factor affects the quality of permanent design of harvest system, and the quality of oil palm fresh fruit bunches is the harvesters’ experience of work. Afdeling 2 has 6 harvesters working for >5 years or 46.2%. The overall findings reveal that the longer harvester's working period, the labor productivity of harvesting oil palm will increase.

Authors: Randi eka putra Refril dani
Published: December 2021

Penelitian ini berawal dari kenyataan di lapangan, yaitu langkanya penggunaan pendekatan dalam pembelajaran dan minimnya penggunaan sumber serta alat pembelajaran. Hal ini disebabkan oleh pembelajaran yang masih bersifat konvensional sehingga siswa kurang berminat mengikuti pembelajaran. Untuk itu penulis tertarik untuk memperbaiki proses pembelajaran membaca memindai dalam pembelajaran bahasa Indonesia melalui pelaksanaan Penelitian Tindakan Kelas (PTK) dengan menggunakan pendekatan cooperative learning tipe Jigsaw II. Pendekatan cooperative learning tipe Jigsaw II ini adalah suatu pendekatan pembelajaran yang memberikan kesempatan bagi siswa untuk berfikir dan berdiskusi dengan teman untuk menjadikan diri “ahli” sehingga mereka dapat menjelaskan materi yang mereka bahas dalam kelompok ahli kepada teman-temannya di kelompok kooperatif (asal), sehingga dalam pembelajaran siswa berperan aktif dan guru berperan sebagai fasilitator. Tujuan dari PTK ini adalah untuk mendeskripsikan bentuk perencanaan, bentuk pelaksanaan, dan bentuk penilaian belajar siswa dengan menggunakan pendekatan cooperative learning tipe Jigsaw II dalam pembelajaran membaca memindai.

Jenis penelitian ini adalah PTK (Classroom Action Research), penelitian menggunakan pendekatan kuantitatif dan kualitatif. Yang menjadi subjek dalam penelitian ini adalah siswa kelas V SDN 08 Padang Besi Kota Padang. Data penelitian diperoleh dengan menggunakan pencatatan lapangan, observasi, dan evaluasi (tes).

Hasil penelitian dari setiap siklus yang dilaksanakan dalam penelitian ini terlihat peningkatan kemampuan membaca memindai siswa dari evaluasi tindakan siklus I rata-rata persentase siswa yakni 65 %, sedangkan pada evaluasi tindakan siklus II rata-rata persentase yakni 78 %. Hasil pengamatan terlihat peningkatan keaktifan siswa dalam proses pembelajaran. Maka dapat disimpulkan pada penelitian ini adalah dengan menggunakan pendekatan cooperative learning tipe Jigsaw II dapat meningkatkan kemampuan membaca memindai siswa.

Apresentamos considerações sobre gênero e raça na Amazônia paraense, a fim de pensarmos sobre os impactos do racismo, do machismo e da misoginia na vida de mulheres negras marajoaras. Para realizarmos estas reflexões seguimos a seguinte trajetória: Primeiro, recorremos a historiografia do negro na Amazônia e os seus entrelaçamentos com o Marajó, para posteriormente nos determos conceitualmente nos termos da identidade, gênero, racismo, machismo e misogenia, para então, por fim apresentarmos os resultados da pesquisa.  Este estudo exploratório, desenvolvido a partir de levantamento bibliográfico, documental e de campo, se constitui em desdobramentos do projeto de extensão “Ser Negro no Marajó” que tem forte articulação com a pesquisa e o ensino a fim de identificarmos demandas quanto ao debate da diversidade etnico-racial na região marajoara. Desta forma, no período de agosto a setembro de 2017 entrevistamos 34 sujeitos, no total, todavia neste estudo damos centralidade às falas das 22 mulheres que participaram da pesquisa. Verificamos que estas 22 mulheres são cisgêneros, servidoras, discentes dos cursos de nível superior e professoras das escolas públicas de Breves/PA. As que se autodeclaram pardas não se percebem enquanto mulheres negras e nem identificam as situações de racismo ao longo de suas vidas, enquanto que as que se autodeclaram pretas, ao assumirem uma identidade negra, relataram diferentes situações de racismo, nos remetendo ao emergente e necessário debate sobre colorismo, mestiçagem e pigmentocracia na Amazônia e no Marajó.

Authors: K.P. Sree Vidhya. , C.S. Siji. , M Nandini.
Published: December 2021

Foreign body aspiration remains a significant cause of death in children for anatomic as well as developmental reasons. Foreign body aspiration is a potentially life-threatening event because it can block respiration by obstructing the airway, there by impairing oxygenation and ventilation. Mothers, as a primary care giver must be aware of first aid management of foreign body aspiration and measures to prevent it. Hence, the study was undertaken to assess the effectiveness of video assisted teaching programme on knowledge regarding first aid management of foreign body aspiration among mothers of under-five children in selected anganwadis under Nadathara Gramapanchayath, Thrissur. The other objectives of the study were to find out the association between level of knowledge with selected demographic variables of mothers regarding first aid management of foreign body aspiration. Quasi experimental one group pre testpost test design was conducted among 30 mothers of underfive children. Samples were selected by using purposive sampling method from 2 anganwadis. Pre test was conducted using structured knowledge questionnaire. It was followed by video assisted teaching of first aid management of foreign body aspiration with appropriate AV aids by the investigator. Post test was done after 7 days and the analysis shows that there is a significant increase in knowledge score of mothers regarding first aid management of foreign body aspiration. Also, the study findings revealed that there is no association between knowledge score of mothers with their selected demographic variables. Thus, the study concluded that the video assisted teaching regarding first aid management of foreign body aspiration was effective in improving the knowledge of mothers.

Authors: George Giby G , Joseph Jisha
Published: December 2021

Introduction: Human milk is the only recommended and complete food for newborn. The benefits of breast feeding are incalculable. It is the unique food for the healthy growth and development of infants. Positioning of the baby is very important while feeding. Correct positioning is crucial for effective breast feeding. This Study was undertaken to compare the breastfeeding self-efficacy among postnatal mother with cradle and football position. Methodology: A quasi experimental post-test only design was adopted to study the breastfeeding self-efficacy among postnatal mothers with cradle and football position. 87 postnatal mothers were enrolled on the first postnatal day using convenience sampling. The subjects were assisted in feeding their newborns in cradle hold position during morning feeds and to adopt football position during nursing in the afternoon time. This pattern of feeding was continued for three days and breastfeeding self-efficacy was assessed on the third day for both positions using breastfeeding self-efficacy scale. Data obtained were analyzed using SPSS Version 20. Result: The mean and median for breastfeeding self-efficacy for cradle position were 54.69 ±4.61and 56 respectively which were found higher than the mean (31.69±3.29) and median (31) for football position. The difference observed in the breastfeeding self-efficacy was found statistically significant (p<0.001) Conclusion: Cradle hold position was found to be effective in terms of breastfeeding self efficacy as compared to football position.

Question -Response in Online Synchronous Videoconferencing Class
Authors: Chaqmaqchee Obaida , Paramasivam Shamala
Published: December 2021

With recent developments in technology and its massive impact on the education field, videoconferencing has emerged as an effective teaching learning tool in the language classroom. It is mainly a means of communication to overcome the impediments of geographical distance and separation. However, despite the successful implementation of this technology, it has been stated that using videoconferencing for online teaching is problematic. Videoconferencing impedes instructor-learner interaction and is unable to replace the traditional face-to-face classroom. To understand online interaction from a sociocultural standpoint, this study examined the characteristics of instructor questions in terms of cognitive level so as to investigate if instructor question can function as a stimulus for interaction in the online classroom. The results show that cognitive level of instructor question can function as an effective factor to promote online classroom interaction. Conclusions and implications are drawn at the end of this paper to help understand interaction in online learning.

Many pathological conditions, like allergy, asthma, cancers, autoimmune, cardiovascular and infectious diseases were attributed to vitamin D deficiency. Could a single deficit be re-sponsible for such a lot of different illnesses? Probably, it could not. The mistake lies in the interpretation of vitamin D suggested serum level cut-off. Vitamin D Recommended Dietary Allowance (RDA) of 20 ng/dl, which is the estimated need for people at the upper limit of the Gaussian distri-bution, was considered like a cut-off. Instead, almost the entire population (97.5%) shows vitamin D needs inferior to 20 ng/ml. This way, a screening based on a wrong cut-off can lead to a useless over-supplementation.

Introduction: Little is known about the impact of enzyme-inducing antiseizure drugs (EI-ASD) on the reduction of Bone Mineral Density (BMD) in men with epilepsy (MWE). Objectives: To evaluate the BMD in MWE exposed to EI-ASDs (phenytoin, carbamazepine and phenobarbital) and its relationship with the duration of epilepsy. Methods: We evaluated BMD from 74 consecutive MWE (median age (range), 52.5 (25- 74) years) exposed to previous or current EI-ASDs, followed at UNICAMP-Brazil. Individuals were split into two groups (young-group, 31 individuals [25-49 years]; older group, 43 subjects, [50-74 years]). The BMD test evaluated t-score indexes from the femoral neck, whole femur and lumbar spine. Osteopenia was defined with t-score of - 1.0 to -2.4; osteoporosis, with T-scores lower than -2.5. Data were extracted from medical records. We analyzed data with SPSS22, performed chi-square tests for categorical variables and applied a partial correlation test (controlled for age) between BD scores and duration of epilepsy. Results: BMD was reduced in 49/74 men (66.2%). Both groups presented equivalent proportions of BMD abnormalities (p=0.087) (young-group [14/41 normal (45%), 12/31 osteopenia (39%), 5/31 osteoporosis (16%)]; older-group [11/43 normal (26%), 16/43 osteopenia (37%), 16/43 osteoporosis (37%)]. BMD did not correlate with the duration of disease or age of onset. Conclusion: BMD reduction is highly prevalent in MWE exposed to EI-ASD, including young individuals. Data suggest that exposure to EI-ASD may associate with early BMD reduction, which evolve to osteopenia and osteoporosis. BMD evaluation in MWE and appropriate treatment may be necessary to reduce fractures’ risk.
Integrative review of the use of NMDA antagonists for TBI treatment
Authors: Ribeiro Fernanda Cristina Poscai , Rodrigues Everton Lopes
Published: December 2021

Introduction: The kinetic energy of TBI generates mechanical deformation, which causes release of glutamate, activating ionotropic receptors, principally NMDA receptors, favoring the flow of Ca++ and Na+ into the cell, producing edema. Then, the neurotoxicity generated by glutamate release can be avoided by NMDA antagonists. Objectives: To define if NMDA antagonists are promising for the treatment of TBI by literature analysis and to verify if there are reports of adverse reactions. Methodology: The review utilized the Scielo and Pubmed databases and the keywords used were: NMDA antagonist, Brain edema and Brain injury. The review contains 5 animal tests and 5 clinical studies. Results: Animal tests: CP-98,133 minimized edema, motor damage and is promising in the treatment of memory dysfunction after TBI. The NPS 1506 reduced edema in 24h, without altering the necrosis significantly. Ketamine decreased the volume of necrosis without altering the edema. HU-211 reduced the edema slightly. Clinical studies: NPS 1506 showed a neuroprotective profile and no serius effects. Traxoprodil decreased the mortality rate by 7%. CP-101.606 improved the patient’s condition, without adverse effects. Conclusion: Although NMDA antagonists demonstrate effectiveness in TBI treatment, more studies about adverse effects and efficiency are still needed. Among those analyzed, traxoprodil, NPS-1506 and CP-101.606 still don’t present serious adverse effects and demonstrate effectiveness, proving promising for new studies.

Published: December 2021

Background:Moyamoya disease (MMD) is a steno-occlusive cerebral angiopathy. The incidence of intracranial aneurysms (IA) associated with MMD is high (3.4-14.8%) when compared to the general population (1-3%). IA in the middle cerebral artery (MCA) associated with MMD are rare, with only 25 cases described in the literature. Methods:Search on the PubMed platform, in English, with the MeSH terms “Moyamoya Disease”, “Intracranial Aneurysm” and “Middle Cerebral Artery”. There were 151 results, of which 7 were included in the review. Results:Sumi et al. and Larson et al. reported non-ruptured IA of the M1 segment, treated by surgical clipping and wrapping, respectively. Endo et al. chose to clip a ruptured IA in the M1 segment, followed by anastomosis between the superficial temporal artery and the MCA, excluding the IA . Liu et al. reported a non-ruptured MCA IA in a pediatric patient, treated through an encephalo-duro-arterio-synangiosis; the IA was excluded. Peltier et al. performed an indirect revascularization using the multiple bur-hole technique in a pediatric patient with non-ruptured IA in the M1 segment, excluding the IA. Rivera et al. opted for the conservative approach of a ruptured IA in the M1 segment, which was successful. Yan et al. described 19 IA in the MCA associated with the MMD, without specifying the adopted therapeutic. Conclusion:Due to the low number of cases, no recommendation can be made, and treatment should be individualized.

Published: December 2021

Background: NMO is a demyelinating autoimmune disorder of the CNS which affects the optic nerves and the spinal cord. Method: review based on papers from 2016 to 2020. Platforms used: MEDLINE and Pubmed. The descriptors: “NMO” AND “Treatment”. Objective: to review therapeutic approaches and restrictions for NMO during pregnancy. Case report: G.V.L, 17 years, 23 weeks pregnant, diagnosis of NMO in Dec/2020, with progressive loss of visual acuity and limbs paresthesia. The patient received intravenous methylprednisolone pulses 1g/5 days, followed by 7 sessions of plasmapheresis (PLEX), showing partial symptoms remission, prednisone 60 mg was maintained. March/2021: she presented symptoms reissue, cranial MRI w/o: nerves signal alteration, chiasma and bilateral optical tracts. Spine MRI w/o: slight signal alteration in the dorsal root of the spinal cord, which extends from C1 to C4. Other 5 sessions of PLEX were attempted, without improvement. Results: during pregnancy, intravenous glucocorticoid, Rituximab and Eculizumab proved to be safe in the treatment of NMO. PLEX is indicated in cases of remissions resistant to medications. The therapy with immunosuppressants, such as methotrexate, mycophenolate mofetil and mitoxantrone, isn’t recommended. These immunosuppressants can cause miscarriage or pose a risk to the fetus. However, the immunosuppressant azathioprine has a safety profile in pregnancy; furthermore, it is considered the most appropriate maintenance treatment in combination with prednisone. Conclusion: due to the risk of miscarriage and teratogenicity, NMO treatment during pregnancy is restrict to intravenous glucocorticoids, rituximab and eculizumab, and in specific cases PLEX.

Authors: Santos João Vitor Ribeiro dos , Spitz Mariana , Andorinho Ana Carolina
Published: December 2021

Introduction: Thrombotic thrombocytopenic purpura (TTP) is a hematological disease resulting from the ADAMTS 13 plasmatic protein deficit. It can be congenital or sporadic, and is usually autoimmune. Pathological platelet adhesion occurs, leading to microthrombi in capillary and arterial circulation, microangiopathic anemia and ischemia. The clinical picture includes thrombocytopenia, renal dysfunction, fluctuating neurological symptoms, microangiopathic hemolytic anemia, and fever. Methods: Case report of a 51-year-old male hypertensive patient, diagnosed with idiopathic thrombocytopenic purpura (ITP) 10 years ago and submitted to splenectomy 5 years ago, who developed acute cholecystitis. He underwent urgent colecistectomy, and on the fourth postoperative day presented sudden space and time disorientation, transcortical motor aphasia and right faciobrachial paresis, with ipsilateral Babinski and Hoffman signs. Results: Brain CT showed left frontoparietal hypodensity. During hospitalization, there was worsening of renal function, increased LDH, and thrombocytopenia. Hematoscopy identified signs of intravascular hemolysis (erythrocyte fragmentation, reticulocytosis, helmet erythrocytes). Direct Coombs was negative. There was no history of heparin use. TTP was diagnosed, and fresh frozen plasma and prednisone 1mg/kg were prescribed. There was resolution of thrombotic microangiopathy, with subsequent increase of platelet levels, decreased LDH and improved hematoscopy. Conclusions: This case illustrates a rare cause of stroke and an unusual association of two hematological conditions: ITP and TTP. The treatment of TTP consists of replacement of deficient ADAMTS13 protein through plasmapheresis or fresh frozen plasma. The use of immunosuppressants is also associated, initially with glucocorticoids, followed by rituximab or splenectomy in order to prevent recurrences.

Authors: Barrios Rada Carmen Rosa
Published: December 2021

El objetivo de la investigación fue identificar actitudes sobre igualdad de los géneros en categorías específicas: orientación sexual, simbolismo religioso, valores y estructura de pareja, ámbito privado, ámbito público y sexualidad-libertad y analizarlos en sus categorías y enlaces, para el efecto se aplicó el Cuestionario de Actitudes de Igualdad de Género (CAIG), con escala Likert, la muestra fue no probabilística con 197 estudiantes mujeres de segundo y tercer año de la Carrera de Trabajo Social, gestión 2021, de la Universidad Pública de El Alto. Se encontró, una actitud neutra, hacía cuatro categorías: Orientación sexual, Sexualidad-libertad, Valores-estructura de pareja, y Simbolismo religioso. No se tienen posiciones definidas respecto a ellas, se mantienen actitudes estereotipadas, por ejemplo, sobre la participación política o adopción de niños por parte de homosexuales, o la libertad sexual de comportamiento respecto a ambos géneros. Finalmente, las categorías de ámbito público y privado fueron reconocidas claramente como espacios donde aún existe inequidad entre géneros. La investigación visibiliza, que en este milenio las nuevas generaciones y las mujeres jóvenes mantienen actitudes poco claras respecto a la igualdad de géneros, y por tanto los espacios universitarios, deben promover actitudes proactivas, referidas a la construcción de una mentalidad de equidad con acciones positivas para el ejercicio profesional.

Authors: KORKMAZ Kübra , SAYĞILI Hasan
Published: December 2021

Bu çalışmada, toksik bir ağır metal olarak bilinen kurşun Pb(II) iyonunun, yeni bir alternatif olarak yeşil nohut kabuğu (YNK) kullanılarak sucul ortamdan giderimi araştırılmıştır. Biyosorpsiyon çalışmaları kesikli yönteme göre yürütülmüştür. Optimum Pb(II) giderimi için gerekli koşullar belirlenerek sıcaklığa bağlı kinetik ve izoterm çalışmaları yapılmıştır. Çalışmalar sonucunda elde edilen kinetik veriler, yalancı birinci, yalancı ikinci ve parçacık içi difüzyon modellerinde değerlendirilerek kinetik model tespiti yapılmıştır. İzoterm verileri ise Langmuir ve Freundlich izoterm modellerinde değerlendirilmiştir. Pb(II) iyonunun YNK ile biyosorpsiyonunda, optimum koşullar biyosorbent dozu 0,1 g ve sıcaklık 40 oC olarak saptanmıştır. Çalışmada, maksimum biyosorpsiyon kapasitesi Pb(II) iyonu için 30,8 mg/g olarak bulunmuştur. Ayrıca izoterm verilerinin Langmuir izoterm modeline uygun olduğu (R2 =0,99) bulunmuş olup, yalancı birinci derece reaksiyon modelinin ise kinetik açıdan en uygun model olduğu (R2 =0,99) tespit edilmiştir. Çalışma, YNK atığının belli bir biyosorplama kapasitesinin olduğunu ve bu atığın düşük maliyetli çevreci bir alternatif olarak kullanılabileceğini ortaya koymuştur.
