Abstract
Pasongsongan Village has various potential economic values, including natural resources, culture, and social values. One of the unique features found in Pasongsongan village that can be developed as an ecotourism is the fresh water resources on the shoreline. The fascination of fresh water sources on the shoreline or Situ Pèngghir Sèrèng in Pasongsongan Village has its own charm to be developed as an ecotourism. We believe that Situ Pèngghir Sèrèng Ecotourism will lead as a market center in promoting local products from Pasongsongan Village if managed appropriately. This study aimed to explore the tourism potential that can be developed and develop a 3D design of Situ Pèngghir Sèrèng ecotourism. Our 3D design greatly illustrates how to facilitate stakeholders in planning activities in Situ Pèngghir Sèrèng ecotourism. This 3D design, in turn, can be used as a beneficial asset for stakeholders to plan, develop and manage the area as one of an ecotourism center in East Java.

Abstract
One of the qualities of biochar is determined by the method in biochar production. The development of methods is carried out in traditional (Soil-Pit), conventional (Drum), and modern ways (Kon-Tiki). Thus, it is necessary to study the characteristics of the method in biochar production. The treatment units were allocated based on a Completely Randomized Design with three replication. The results showed that the characteristics of bamboo biochar based on the method of biochar production has a significant on the duration of firing and moisture of biochar and chemical properties of bamboo biochar on pH, EC, liming potential, proximate analysis, CEC, and cation bases (K, Ca and Na-exch), C Inorganic and C Organic. The best method of production of biochar bamboo is modern ways (Kon-Tiki) because it has effective time in the process production, high moisture, yield ratio compared to other methods, and less smoke so it can reduce air pollution.

Authors: Carvalho E F M de , Syaufina L , Hermawan D 
Published: January 2022

Abstract
Firewood has been a common traditional energy source used by communities living in villages and cities in Timor Leste. About 80 % of villagers use firewood as an energy source, which puts pressure on forest disturbance as demand increases. Therefore, energy forest plantation can be an important alternative for forest disturbance solutions and fuel reserve for the community. The paper aims to review the possibility of the development of energy forest plantations in Timor Leste. The literature review applied for publications in 2015-2021 with the keywords of Timor Leste, energy plantation forest, and firewood using the Publish or Perish tool. We found 886 publications related to the keywords, whereas only 65 publications contained the keywords. The reviews indicate that the pressure on the forest due to firewood collection has been on the increase. Therefore, energy forest plantation is a vital alternative to solve forest disturbance in Timor Leste.

Authors: Akbar A 
Published: January 2022

Abstract
Regionally, the Tumbang Nusa area consists of Tumbang Nusa village and Tanjung Taruna which also include a special research forest area under the management of the Ministry of Environment and Forestry. The area is a peatland with a peat soil depth between 2-8 meters so that is representative of the impacts of peat fire events on areas of moderate until deep peat depth. Experience from fire events at the mentions area in 2019 can be used to guide improvements in fire prevention strategies and management plans for preventing future surface and peat fires. Our research has shown that reducing the probability of a fire occurring requires an understanding of the socio-economic factors, such as human activities which ignite fires. This should be coupled with an understanding of the supporting biophysical and social factors including peatland characteristics, involvement of fire brigades, police and army, management of fuel, local fire danger rating, fire equipment, institutional capacity, suppression response, and post-fire action. All of these learning elements can improve prevention techniques at the village level.

Published: January 2022

Abstract
White oyster mushroom (Pleurotus ostreatus) is a mushroom that is often consumed by the public and cultivated because it has a high nutritional content and a wide variety of essential amino acids, proteins, fats, minerals, and vitamins. This study aims to analyze the response of several ligno-celluloses materials to the growth of white oyster mushrooms, to compare the treatment of several ligno-celluloses materials to the growth of white oyster mushrooms, and to determine the appropriate concentration on the growth of white oyster mushrooms. The experimental design used in this study was a Factorial Completely Randomized Design (CRD). As the result of the interaction test, the P-value obtained is 0.999>0,05, thus h0 is not rejected. The test of seeds obtained p-value 0.005<0,05 h0 is rejected, based on the test of the influence of planting media obtained p-value 0,000<0,05 h0 is rejected. From the graph of the average comparison, it is known that the type of F3 seed on the M4 planting medium caused the highest duration of mycelium growth compared to the influence of the type of seed and other growing media.

Abstract
The connectivity of the Peat Hydrological Unit (PHU) management through the development of multi-business based-on agroforestry landscapes has not been widely studied. Synergism in the development of PHU connectivity can be done through the determination of superior commodities in each physiography. The superior product per physiography in the PHU is an integrated cluster both vertical and horizontal value chain. This is known as a Porterian cluster. This study aims to build the concept of PHU connectivity through the development of multi-businesses based on agroforestry landscapes. The research was conducted in Tumbang Nusa Village. The study showed that natural and physical capitals in all categories of villagers of Tumbang Nusa Village are categorized as high and very high, respectively, while the availability of human capital in all categories is low. The availability of financial capital for the villagers of Tumbang Nusa Village in Category I is high, moderate for categories II and III, and low for categories IV and V. The availability of social capital for citizens in all categories is high. An important source of livelihood for the households of the villagers of Tumbang Nusa Village is natural capital, financial capital and social capital which comes in various forms. The contribution of agroforestry to the total income of farmer households ranges from 22.81% - 79.80%. The adaptation strategy that is mostly carried out by households in all levels of welfare categories is the economic adaptation strategy.
Optimal design of photon-sieve holograms for fine-line image generation
Authors: Sugisaka Jun-ichiro , Onishi Ko 
Published: January 2022

Abstract
A photon-sieve hologram (PSH) is a computer-generated hologram that can generate fine-line images. As a high-resolution image can be projected directly without using a reducing optical system, it can also be used for short-wavelength radiation, such as x-rays. We propose an optimum design method for the PSH so that a high-quality line image can be projected. We optimised straight-line and L-shaped bent-line images using numerical simulation based on vector diffraction theory and conjugate-gradient methods. This optimisation helped homogenise the intensity of the image and remove unwanted side lobes and spots around the image. We also experimentally examined the bent-line image before and after the optimisation to confirm its effect.

Published: January 2022

Abstract
Titanium alloys fabricated by selective laser melting (SLM) are typically subjected to post-treatments, such as shot peening, to improve the mechanical properties. However, the same Almen intensity may correspond to various combinations of peening parameters, which will generate different microstructures and comprehensive properties. Herein, the SLMed Ti64 alloy was treated by pneumatic shot peening (SP) and ultrasonic shot peening (USP) under the same Almen intensity of 0.2 mmA, investigating the changes of the microstructure and corrosion resistance. The average surface roughness (Ra) of the SPed sample was 1.806 μm, which was significantly higher than those of the USPed samples (0.942 μm and 0.999 μm). The USP and SP treatments led to the surface plastic deformation and grain refinement, while the SP produced a smaller crystallite size. The SP treatment led to the biggest surface and max compressive residual stress, which were −654.0 MPa and −805.5 MPa, but the USP resulted in thicker compressive residual stress layers. The USPed sample reached the highest microhardness (443.2 HV0.025) and the thickest hardened layer (247.8 μm). The USP and SP samples offered superior corrosion resistance, but the USPed samples showed higher corrosion potentials and lower corrosion current densities.

Published: January 2022

Abstract
Tumors with high mortality rates are still a major threat to human survival and health worldwide. In recent years, cancer immunotherapy has made rapid clinical progress in eliminating cancers by activating the host’s own immune system. Particularly, the use of physiological bioactive gas molecules such as nitric oxide, carbon monoxide and hydrogen sulfide have been developed as novel immunotherapeutic strategies. In this review, we have summarized the current strategies for antitumor immunotherapy via bioactive gas molecules, targeting delivery to the tumor microenvironment. We summarize the biofunctions of bioactive gases to the immune system, then gas delivery nanocarriers for antitumor immunotherapy and the current status of the platform are presented. Furthermore, since gas could specifically respond to the ultrasound, ultrasound-assisted gas delivery is generalized as a promising potential pathway for enhanced immunotherapy. Finally, we have discussed the challenges and opportunities for bioactive gas delivery and the effects of acoustic enhanced immunotherapy in future developments and possible clinical applications.

Published: January 2022

Abstract
Mature granulated trophoblast binucleate cells (BNC) have been found in all ruminant placentas examined histologically so far. BNC are normally fairly evenly distributed throughout the fetal villus and all their granules contain a similar variety of hormones and pregnancy associated glycoproteins (PAGs). Only the Giraffe is reported to show a different BNC protein expression, this paper is designed to investigate that. Gold labelled Lectin histochemistry and protein immunocytochemistry were used on deplasticised 1 μm sections of a wide variety of ruminant placentomes with a wide range of antibodies and lectins. In the Giraffe placentomes, even though the lectin histochemistry shows an even distribution of BNC throughout the trophoblast of the placental villi, the protein expression in the BNC granules is limited to the BNC either in the apex or the base of the villi. Placental lactogens and Prolactin (PRL) are present only in basally situated BNC: PAGs only in the apical BNC. PRL is only found in the Giraffe BNC which react with many fewer of the wide range of antibodies used here to investigate the uniformity of protein expression in ruminant BNC. The possible relevance of these differences to ruminant function and evolution is considered to provide a further example of the versatility of the BNC system.
Preserving Oocytes in Oncofertility
Authors: McClam Maria , Xiao Shuo 
Published: January 2022

Abstract
The prodigious rise of cancer survival rates enables many cancer survivors to live long lives. Therefore, the side effects of cancer treatments as well as the long-term quality of life after cancer have become more relevant. Ovarian toxicity is a major off-target effect of anticancer agents for childhood and young adult female cancer patients. Both chemotherapy and irradiation have been demonstrated to damage the ovary and increase the risks of premature ovarian failure (POF), early menopause, ovarian endocrine disorders, and sub- or infertility. Oncofertility is an emerging and multidisciplinary research and medical field that focuses on providing cancer patients with fertility preservation options. Oocyte quality and quantity are one of the most important factors to determine women’s fertility success; therefore, preserving oocytes is paramount for maintaining the ability of young female cancer patients’ reproduction after their recovery. This review summarizes peer-reviewed literature on current oocyte preservation options in oncofertility. We describe in-depth oocyte and embryo cryopreservation, ovarian suppression, ovarian tissue cryopreservation, in vitro maturation, ovarian transposition, and adjuvant therapy. Further, we discuss current guidelines and practices of female fertility preservation that cover preserving oocytes.
Lyme carditis manifesting with sinoatrial exit block: a case report
Authors: Büscher Antonius , Doldi Florian , Eckardt Lars , Müller Patrick 
Published: January 2022

Abstract

Background
Lyme disease is the most common vector-borne disease in North America and Europe. Infection with the spirochete Borrelia burgdorferi complex can involve cardiac tissue causing Lyme carditis (LC). Due to the infection of conductive tissue, LC typically presents with varying degrees of atrioventricular conduction block. Here, we provide the first evidence that conductive tissue of the sinus node can be involved in LC resulting in higher degree sinoatrial (SA) block with concomitant syncope.

Case summary
We report the case of an otherwise healthy 31-year-old female presenting with LC manifesting with SA exit block causing asystole over 12 s with concomitant syncope. Signs of SA block completely resolved with antibiotic treatment with a third-generation cephalosporin. The patient did not require permanent pacemaker implantation and had no sinus pauses after 12 months of follow-up as confirmed via implantable loop recorder.

Conclusion
The possibility of LC in patients with sinus node dysfunction should be considered, as adequate antibiotic therapy can spare patients from potentially unnecessary pacemaker implantation.
